Idea for Guard to Prevent Robot Vacuums from Getting Stuck Under Furniture

Robot vacuums invariably get stuck under some piece of furniture (often couches). Solution--an adjustable-height "visor" along the front perimeter, to prevent the robot from going under the problem furniture that is going to get it stuck.

I guess a complication is that it is not enough for the visor to extend upwards, preventing entrance. That might just cause the unit to stall. It needs to extend down, over the bumper, which is what prompts the unit to redirect when it hits an obstacle.

Although I think there is a software fix. If the unit is not moving for 10 seconds, even if the bumper is not activated, assume it has hit an obstacle, and change direction.

Insert Hyperlink

CTRL-K seems to be pretty nearly universal shortcut functionality for editing a hyperlink. That's good, I use it a lot. The correct implementation (IMO) is for the modal dialog to place the focus into the link/address text input box. Most apps to that.

Webex Chat and Confluence are annoying outliers that place the focus on the text displayed. At least for the way I always, instinctually use CTRL-K, this is dumb and pointless. I have just typed a phrase I want to link, and have selected it before invoking CTRL-K (select-then-do UI metaphor). Or alternatively I am editing something I have written, and identify a phrase that needs a link. In either case, the display text is already written and selected--I effectively never expect to change that in the modal dialog.

Blogger lands in the middle--it doesn't default the focus anywhere. So I don't wind up typing in the wrong place without noticing, which is a small improvement.

Is this just a me thing? Are there other common use cases/workflows where the semi-standard default doesn't make sense?

Used 2019 Crosstrek PHEV vs ICE Decision

Mid-2024, we were somewhat unexpectedly in the market for a vehicle. When we bought 2 new cars almost 10 years ago, I vowed/predicted that my next vehicle purchase would plug in--possibly fully electric, and minimum plug-in hybrid. Not great timing, though,, because EVs still carry a stiff premium and have somewhat limit selection, PHEVs aren't cheap either and are less attractive now that full electric is common. And obviously terrible timing to commit to a new ICE vehicle. 

So we were definitely going the used route--about 5 years old, max 60K miles. The car would be my wife's, and she wanted a Subaru Crosstrek. She pointed out that it does have a plug-in hybrid option. I did some research. The Crosstrek seemed very solid, I couldn't come up with any reason to object to the ICE version--other than the fact that it was ICE. There are alternatives obviously, but nothing stands out, so if she wants a Crosstrek, why not?

But the reviews on the Crosstrek plug-in hybrid were very negative. So negative that I initially rejected the hybrid option it out-of-hand. But then I thought more about why the reviews were negative:

1. High cost: PHEV is only available in Limited (top) trim level, which already commanded about $10K over base. PHEV adds $7000 on top of that.
2. Worst-in-class electric range of 17 miles.
3. Battery pack eats into cargo space.

#3 was not too big a deal for us, since we don't have kids to haul around, and our other vehicle is a minivan. #2 is definitely a bummer, but 17 electric miles is better than none, so it really comes down to cost.

Regarding cost, we were already in the market for the top-line Limited trim--the only trim offered for the PHEV--so the PHEV premium new would have been $7000 (that's in 2019 dollars & prices). In researching used 2019 Crosstreks, I noticed the hybrid only cost $3000-4000 more (2024 dollars) than the ICE with Limited trim line. Quite a discount. After the requisite several days of agonizing weighing the decision, I decided rationalized going with the hybrid.

My rationale involved multiple dimensions, of which cost was only one among several.

Cost: at our annual mileage and gas/eletric costs, the annual savings would be about $300. Not compelling on its own, but worth maybe half of a $3000 premium (applying a financial discount factor for the time value of money).

Environmental: I expect the PHEV as driven by us to get 45 mpg, vs 29 for the standard ICE. That is a meaningful reduction in CO2. If gas cost what it should, I wouldn't have to think past cost, so I weight this about equal to cost.

So the first 2 factors make it a toss up. The deciding factors that pushed my rationalization engine over the finish line, to go PHEV:

Electric Niceness: for those 17 city miles, the smooth & quiet of electric is a pleasant thing.

Power: Nobody buys a Crosstrek for its power. I'm not a power guy, so that's fine. Still, the hybrid is about 10% better for pickup, so that's also a nicety, if it comes along for the ride.

Reverse Range Anxiety: the primary driver of the Crosstrek is known to be in a rush and come home with a tank run so low that it requires a separate trip, later that evening, to be sure there is enough gas to get to the destination in the morning. With the 17 magical electric miles, that concern disappears.

Fast Heatup: also a nice thing to have when you live in Minnesota.

There were a couple of negatives factors to consider for PHEV:

1. Hard to get outside of CA and the few other states they were sold new (never available new, for love or money, from MN Subaru dealers).
2. Limited color selection.

As luck would have it, a very attractive 2019 showed up in Carmax just when I had made my decision. It carried only a $250 transportation charge, which is as good as it was ever going to get. Unfortunately it was white--just about my last choice for color. I sucked it up, and white it was.

Secondary Devices A Minor Chink in the 2FA Security Armor?

Am I missing something, or are secondary devices (e.g. tablets) a bit of a 2FA weakness? E.g., if I know your phone PIN, it might still be very hard to get hold of your phone to leverage it for 2FA. But if you have a tablet that doesn't get daily use, that could be much easier to get hold of unnoticed. It's still low-percentage for most people, of course.

Barely Avoided a Car Crash

Driving on the highway through St. Paul, going low end of highway speed. Coming around a bit of a curve and all of a sudden I see a car in my lane, mostly facing forward, and a second car in front of the first car, this one at a diagonal, clearly struck by the first car. I braked hard, but realized I wasn't going to be able to stop without a collision. It wouldn't have been too bad, I would have lost a lot of speed by the time of impact, but it would have done catastrophic body damage at minimum. 

It was almost like I was in a video game. I saw that there was a comfortable car's width of room in the shoulder. And my trajectory from the curve was favorable to maneuvering in that direction. So I let up on the brake and swerved right. I was confident I would avoid a head-on collision, but I remember thinking that I would probably make contact in the rear. But to my wonder, I sailed right through, unscathed. It probably helped that I happened to be driving my son's car, a compact Ford Focus hatchback.

I was already planning to get front/rear dashcams, this is why.

Universal Dash Phone Holder Slot

I've used a number of different cradles for mounting my smart phone in the car. The CD-slot ones seem far superior--if you have an old enough car that it has a CD slot. Which makes me wonder--why isn't there a a universal phone-mount slot standard? It wouldn't have to be nearly as wide as a CD-slot. For extra credit, it could also provide a charging port or maybe even wireless charging.

I know, if you have Android Auto or Apply CarPlay, you may not need to mount your phone while driving. But not all cars have them, and there are apps that don't support them, and also there are automakers that don't support them. Also, wireless use can be iffy, and sometimes you are in a hurry on a short trip, and not interested in connecting the cable (if you don't have wireless). Or maybe a passenger is connected to the audio.

Luxury of excessive battery life

I am a super-heavy earbud user. I have a pair of SoundCore A40 earbuds that has ridiculously good battery life, both in the buds and the case. So good that I don't have to devote any time to worrying or managing the battery. In 2 years of heavily daily usage, not one time have I run out of charge or had to conserve. That is such an under-rated luxury!

Which makes me wonder--how much bigger would an iPhone have to be (for sake of argument, let's say the mainstream regular size iPhone 16) to double the battery life? I would certainly accept a 1/3 increase in volume for that!

Don’t Even Think of Using Semi vs Bi-

 As in bi-weekly or semi-weekly. Even if you are rock-solid on your usage, there is a very high chance your audience is not.

Is Denialism the Original Sin, in the Contemporary Republican Party

TL;DR I maintain that it was not just a very unfortunate turn of events that allowed the MAGA mentality to completely take over the Republican party, and that it is not so hard to imagine different circumstances leading to a left-wing version of it. 

In a "Beg to Differ" podcast episode (43:13) a few months ago, Mona Charen took a run at a form of half-hearted apologism for the conservative movement, by trying to make the case that the contemporary descent into MAGA madness was circumstantial, and one could imagine something comparable happening in the democratic party: 

I do think that it’s too easy to say it had to happen this way because I don’t think it did. I think the party had many more it was mostly full of normies. And then Trump came along, and he kind of stripped away the barriers, and the normal inhibitions that most people have, and suddenly people fell in line.

The "mostly full of normies" part is where I differ. Circa 1980, that was a fair statement. Where the seeds of madness were sown, in my view, is when the mainstream/secular right made an unholy strategic alliance with the emerging religious and populist right. In my view, the two camps didn't have that much in common, beyond sharing a common opponent, "big government". 

In particular, these groups were devoted to particular issues/beliefs are so utterly contrary to facts, that they can only be maintained through denial of facts. At the top of the list: Creationism, Guns Are a Positive Good run-rights maximalism. And the "no compromising" rhetoric that is the antithesis of democratic politics, but inherent to dogmatically-held beliefs. These issues were the gateway drug for Denialism, which spread and became both a habit of existing Republicans, and a draw for new ones. It was less than a generation ago, for instance, that anti-vaxism was associated with the far left, but now the right is the home of the anti-vax crowd.

(For the record, I appreciate and support both the podcast, and Mona Charen. It's just that I have to "beg to differ" on this one.)

Wine Rating Scale

I am so tired of the numeric wine-rating scale popularized by Robert Parker. It is meaningless, every bottle wants to be 89-93. Some ideas for improvement.

Overall

That would be the Robert Parker-style score. But even in this category, we need to re-calibrate. 100 points is way too many. 20 would probably suffice. 

1: Actively disagreeable.

• 2: Utterly bland and uninteresting. Someone who is utterly indifferent to wine and in the mood for an alcoholic beverage might drink it, but for anyone with even a modicum of wind appreciation, not worth the calories.
• 3: Would drink as a last choice if in the mood to drink wine and no alternative.
• 4-15: Relative ratings for wines most people are likely to drink--max price $50/bottle.
• 16-20: for the elite.

As an Exemplar of Its Category

Assuming the wine fits a well-established category (e.g., New Zealand Sauvignon Blanc), how well does it express the qualities expected of the category? Sort of like how a dog show judges an animal's features not in the absolute, but relative to its breed.

Under the Right Circumstances

Most likely factor to influence this would be food pairing. E.g., this wine is generally rough, but with really spice food, it holds up. This category is a bit loose, if not careful, it could be an excuse for grade-inflation.

Value

Graded on the curve of price.

Multi-Factor Console for Updating Critical Business Parameters Executed by Software

Major business policies, especially in financial services, are often driven by some simple parameters that are executed in software. E.g., for a lender, what interest rate is being charged.

There is typically a dashboard accessible to a small number of users with authorized elevations, to enter these values. In general, that works fine, but there may be concerns about data-entry mistakes or deliberate sabotage (less probable). I think a good solution involves:

• Purpose-built UI (console), limited of course to an appropriate, small user group.
• Require multi-factor -entry to implement a change: i.e., 2 or more members have to independently submit the update (exact number is configurable, depending on the sensitivity--but in general, I think 2 is the magic number).
• Add some UX niceties for workflow—e.g., showing pending updates where only 1 entry has been made, reminders if 2nd entry is overdue.
• Email the entire group whenever a change is initiated and completed.

Email Feature: Reply All "Discouraged"

In email,  I feel like we need a middle ground between:

1. The standard open distribution list, that tends to encourage the default behavior of Reply All;
2. The bcc technique that prevents this, but makes it impossible both to see who is copied, and to Reply All if it is indeed appropriate.

So the Reply-All-Discouraged feature I envision would operate as follows: 

1. Have to be consciously invoked. Perhaps even explicitly enabled in user settings.
2. Set explicitly on a per-email basis. Sender could optionally provide explanatory rationale for when Reply All might be appropriate.
3. When a recipient clicks Reply All, they would get a pop-up with a generic explanation of the feature, and any explanatory text from the Sender.

While making this work universally would require a formal or informal standards change, I think Gmail and Outlook have enough market share to implement independently, and get significant value out of it. For out-of-platform recipients, it would have to default to bcc. 

Brueggers Bagels Quality Control Opportunities

I love bagels, I eat one for breakfast 5 days a week (used to eat 2!). We don't have a lot of choices, Bruegger's is the best around. I mostly get Everything.

So I have been patronizing the local Bruegger's heavily for about 15 years. I buy a dozen, and freeze them for daily consumption, so I am in the store every couple of weeks. There are some significant consistency problems. Here is a sample bagel from this week:

Seed coverage very inconsistent. Sometimes it is heavy (ideal), sometimes very light (unacceptable), sometimes moderate (acceptable). In this case, the sample is the high side of moderate (less seedy underneath).

Done-ness is similarly inconsistent. I personally like my bagels on the browned side--this one is about perfect. They are often far lighter.

Handling. Bruegger's uses paper bags rather than cardboard boxes. They cram delicious, hot, fresh bagels into a small-ish bag, and they get mushed--the photo is a good example. There are easy solutions. One would be boxes, like Einstein's and Panera. The other would be much bigger bags.

Online ordering (bonus complaint). The mobile app does not allow you to create a custom dozen (and the website doesn't seem to support online ordering at all. To the credit of my local store, they are very good about actually answering the phone when I primo "3" in the IVR.

NYC Experimenting with Noise Pollution Enforcement Cameras

A small step in the right direction. I do not understand why US society tolerates such abusive, anti-social, unnecessary, deliberate noise pollution assault.

Beck and Call vs Beckon Call

I was well into my thirties before I learned that the correct expression is"beck and call", not "beckon call". In fact, the first time I encountered it, I assumed the writer (a business colleague) had made a sophomoric mistake.

In defense of my error, "beckon call" reminds me of other terms such as:

• borning cry
• siren song, swan song
• death rattle

Clearly the grammatically correct usage would be the gerund form, beckonING, as is the case with borning cry. But beckon is already a two-syllable word, and also a less-common word, which I would argue lends itself to a tendency to shorten, for metrical felicity.

My next example is "Siren song". This is not a perfect parallel example, since it does not involve a gerund, but illuminating in that it is an example of shortening for convenience (7.0M Google results for Siren, 1.4M for Siren's). Swan song is even more dramatic--"Swan's" yields very few matches.

My final example is "death rattle", which I see as being substantially parallel. "Dying rattle" barely registers in search numbers--though amusingly, the second hit is a brief poem that addresses the very point that death rattle is the more appealing phrase.

**********************************

So I think that is all a good argument that it is almost a sign of good linguistic judgment to assume "beckon call", if one has never seen the term in print. 

But the most compelling, in my mind, is the Occam's Razor take: "beck-and-call" sounds like a textbook example of the simplified, monosyllabic phonetic rendering that is the hallmark of a typical mondegreen(!)

Egg corn vs Mondegreen

I've long been a connoisseur of mondegreens. Only more recently have I become aware of a devilishly similar term, eggcorn. I just spent 15 minutes researching the compare-and-contrast, and I am not sure this is settled law. My quick take: Mondegreens completely alter the meaning of the phrase, while eggcorns keep it at least adjacent (chomping at the bit vs champing at the bit).

Some sources claim that mondegreens are distinguished by a nonsensical meaning, but I think that is a side-effect, not the main effect. I.e., very often the completely different meaning will be off-the-wall, but not always. In fact, the founding mondegreen changes the meaning substantially, but in an entirely sensible way.

Where Are the Smart Monitors?

 During daytime, I set my monitor to 100% brightness. At night, I dial it down to 70%. Why can't this be automated?

Stories are dangerous

I have a longstanding fixation on the downsides of the human love of a good story. This article totally nails it.

Stories act like an anaesthetic on our sceptical, questioning faculties. It can be valuable and pleasurable to subdue that part of our brain, and immerse ourselves in an imaginary world; I love reading stories, including non-fictional ones. But if you come across a history book, or a scientific study, or a news report, which tells a great story, or which slots neatly into a master-narrative in which you already believe, you should be more sceptical of its truth-value, not less. Narrative can give an illusion of solidity. When the expert narrative about the world changes, as with China (see below), we shouldn’t just conclude that the old narrative was false, but that all such narratives are unreliable.

Scientific Explanation for Dog's "Sixth Sense"

Over the years, I have read and heard many stories of dogs seemingly supernatural ability to sense when their master is coming home, or when the mail truck is on its way, etc. I believe there is some tendency among humans to treat this as a magical "sixth sense". Or to over-credit the sense of hearing: "dogs can differentiate the sound of their owner's car/school bus from 5 miles away"--I'm definitely calling bs on that one.

But as so often is the case, there is a known or posited scientific explanation. This article focuses on the time-decay of smell, in combination with other cues, as the explanation. E.g., the family children, in this case, arrive home from school on a school bus. The departure and arrival times of school buses are pretty predictable, I bet +- 5 minutes 95% of the time. The rate at which the children's scent decays is the main clue. This signals to the dog that arrival is imminent, prompting it to lurk in anticipation near the door.

The final part of the magic trick is delivered by the acute--but not magically powerful--sense of hearing. The dog lurks near the door, and they do hear the vehicle far sooner than any human would. They react in anticipation, completing the illusion that they have a magical superpower.

Encountering scientific explanations is ultimately much more rewarding than crediting far-fetched or magical explanations of phenomena.

Apple Should Sell A Viewclix Killer

Viewclix is a popular photo-frame device whose canonical use case is to allow family members to share photos with an older relative who is not up on technology. It also has secondary uses of push teleconferencing (you can initiate the teleconference remotely, without a tech-challenged elder having to do anything), and posting reminders to your loved one ("remember, we will pick you up today at 11:00 for lunch"). 

It does work okay, but the usability, for photos in particular, is very clunky. So clunky I found myself putting off updating the photo rotation, which was the main reason for getting the device. I have since confirmed a much better solution for updating the photo frame functionality: simply deploy a spare TV or monitor, equipped with Chromecast, as a remote Google photos sharing device. Just a few, simple steps:

1. Set up a shared album(s).
2. Invite other family members to be contributors or administrators (depending if you want to let other delete, as well as add, photos) to the shared album.
3. Set Ambient Mode on the Chromecast to show the shared album(s).

Voila!

In addition to the >> UX, you also get a WAY bigger, TV-size screen. However, the roll-your-own with Chromecast does not address the other use cases. Which is why I think this is a great product opportunity for Apple (or Google, or Microsoft, but especially for Apple).

This is probably not an Airpods or Watch-sized market, but it is surely in the millions, in the US alone. Plus it would have strategic value, in strengthening the overall Apple ecosystem value proposition.

Bagel Inflation

9 years ago, in 2014, I could get a dozen bagels at Bruegger's for $6.99. Today, I am paying 14.49, including the $1 tip that didn't used to exist (at least not for me, especially paying by card). So one could say that the price has doubled in less than a decade, which seems economically shocking.

But it is intellectual malpractice to compare prices across time without factoring in the CPI. Adjust for CPI, I was actually paying $9.03 Still, that is 60% excess inflation. Granted, that was using the $2 off per dozen they had every Wednesday, since discontinued. Ignoring that, we are down to 25% excess inflation. If we also remove the tip, down to 16% excess inflation. Still quite a bit, no matter how you slice it.

Decreased Family Size & Social Class Concentration

From a purely statistical point of view, smaller family sizes decrease the likelihood of having close relatives who fall into more economically disadvantaged status. For instance, in a middle-class family of 6 siblings, it is not hard to imagine that 1 or 2 might, for various reasons, wind up experiencing substantially lower standards of living. This might tend to create empathy in more well-off layers of society, since they have close experience of those in a less-advantaged economic class.

In a family of 2 siblings, the statistics are greatly reduced. Then on top of that, there is the generational wealth factor. A comfortable family will be able to deploy more resources to help prevent or assist a child who might be in danger of slipping economically.

Bigger batteries would be so worth it

The achilles heel in the lifecycle of a lot of rechargeable devices is battery life. Lithium Ion batteries diminish steadily, often in 3 years they are about half of what they were when new. For a lot of products, I think a reasonable solution would be just provision them with a bigger battery to start. Instead of making each generation of mobile phones a bit thinner, use that space for more battery.

I was a devoted user of the Jabra Elite 65t earbuds for 5 years. The main reason I replaced them was battery degradation. When they were new, battery life was good, not great. I use them in large part for conference calls, so maybe 4 hours, with the case providing about 8 more hours. So I could often get by charging them once mid-week. By the end, I had to charge them every day, and on heavy days, they needed a top-up.

The replacement Soundcore A40 are a decent upgrade, but not all that huge, for being a 5-years-later product. The one area they really shine, though, is battery life. Out of the box, they get 6-8 hours battery life, and the case has 4X charges (vs 2X for Jabra). They almost always last all week.

Like a Kindle, even when you get the low battery warning, you probably easily have a day left (including what's in the case). It's great, more than I really need. But the beautiful thing is, even if it degrades by a full 50%, it will still be very, very good!

Google Should Buy Tile

I have been a pretty hardcore user of Tile Trackers for 7 years. At this point, I even have one in my travel kit, to attach to rental car keys. All in all, they have worked pretty well. But finding things via crowd-sourced location (leveraging all the Tile users out there as an ad-hoc mesh) has been pretty hit-or-miss, the few times I have used it. Whereas the Apple Air tags have the opposite problem--they are very good at "phoning home" to report location, and that is causing a major privacy problem.

So when I thought to use a bluetooth tracker to monitor my luggage, the Apple Air Tag was the no-brainer choice, even if it is twice as expensive. The fact that its network includes not just other Air Tags, but also iPhones, gives it an overwhelming network scale advantage.

Which got me thinking--Google should buy Tile (or, should have bought). Overnight, it could match Apple's network coverage.

Eleminate charge fouls in basketball

I totally agree with this article, assuming that it does not literally advocate abolishing the very concept of a charging foul. Growing up playing basketball recreationally, and watching as a casual fan, I thought of charging as something usually pretty clear-cut and obvious, and therefore rare. When I got back into basketball fandom after a several decades absence, I was very surprised to see how charging works--the defender races the driving offensive player to a spot, and has their feet planted a tiny fraction of a second first. They thus establish position, putting their body on the line to draw the foul from the offensive player whose momentum is unavoidably carrying them toward the contested real estate.

The same test that has been applied to offensive players aggressively courting foul calls by unnaturally contorting their bodies mid-jump-shot should apply here: his is not a basketball move.

I would not buy a new ICE vehicle

At this point, no way would I buy a new ICE (regular gas-powered) vehicle. I personally am in a good phase in the car-replacement cycle, easily 4 years from wanting (longer from actually *needing*) to replace one of ours. But if I were otherwise ready for a new car, I would either put it off, or buy something (substantially) used. I think we are at the point where ICE is a very poor investment.

I do wonder if, a few years down the line, there will be havoc in the auto market, where nobody wants to buy ICE, but EVs are still a minority of production?

Chromecast vs Viewclix

Viewclix is a popular photo-frame device whose canonical use case is to allow family members to share photos with an older relative who is not up on technology. We got one for my mother about a year ago.

It does work okay, but the usability is clunky. I have found a much better solution is to use a spare TV or monitor, equipped with Chromecast, as a remote Google photos sharing device.

1. Set up a shared album.
2. Invite other family members to be contributors or administrators (depending if you want to let other delete, as well as add, photos) to the shared album.
3. Set Ambient Mode on the Chromecast to show the shared album.

Voila!

In addition to the >> UX, you also get a WAY bigger, TV-size screen.

(Granted, Viewclix has secondary use cases of teleconferencing, and posting reminders to your loved one. The Chromecast solution does not tackle those.)

Airline flight change offer

First time I have ever gotten this kind of offer to proactively re-schedule my flight, if I happen to find that convenient. If this is what I think it is, it is different than an offer to sign up to be "bumped". Those typically are on a bidding system--how much would you take in compensation to be bumped to a different flight?

If I am interpreting correctly, this is saying "hey, if you happen want to change your flight, we won't charge you for it. Do you want to take a look and see if a different flight would be an improvement?" I've thought for ages that airlines should do this kind of thing--see if there is a win-win to be had.

(I didn't pursue the offer, so I don't know for sure how it worked.)

Optional Handling of Canceled Events

Online calendar software such as Outlook and Google Calendar always removes canceled events, once you accept the cancelation notification. That's often reasonable and fine. But sometimes, especially for recurring events, it is helpful to see an explicit notice of the cancellation. E.g., I don't have to get to work early next Thursday, because the weekly coffee club isn't meeting.

It is a somewhat esoteric feature, and probably tricky to design the UI for, but it really could be nice, for some of my use cases. One way I can think of to implement it is for the calendar to ask you, when you accept the cancellation, whether to hard-delete or logical delete. And then it could include an option for "don't ask me this in the future".

EU USB-C Mandate: Compromise via a Sunset Provision

With the advent of USB-C, the device world has been approaching common-standard nirvana. To-date, Apple has remained the stubborn holdout ruining the fun. Maybe Apple would have cleaned up their act this year on their own, but it's hard to know, since the EU did it for them, with a 2024 mandate to standardize on USB-C.

Very few people, I think, disagree with the outcome of this particular regulation, but you do hear various degrees of concern about prescriptive mandates. I.e., maybe a company would innovate and produce a superior connector, better to let the market decide.

I think building a sunset provision into regulations like this would be a pragmatic compromise. E.g., let the regulation expire in 4 years. That leaves a reasonably foreseeable time horizon where USB-C is completely adequate, so by the time any hypothetical innovation is mature, the path will be clear for testing it in the market.

At the same time, the arrangement should remove any motivation to game the system. E.g., after switching to USB-C, Apple isn't likely to switch back when the regulation expires.

Podcast App Feature: Skip Intro/Outro

Some podcasts have annoyingly long intros, or ads at the beginning. Lots of podcasts are padded with ads at the end. Both are annoying. If you are in a position to fast-forward, they can easily be skipped, but if you tend to listen in "hands off" mode (driving, exercising, doing things that get your hands dirty like cooking), this isn't a good option. 

A killer feature for a podcatcher would be to allow, on a per-podcast basis, a user-configurable setting for skipping intro and outro.

Bluetooth Needs a (Don't) Connect Automatically Option

It has to be a common family scenario (in the car-centric US, anyway) for a couple to have 2 cars, with each paired to both spouses' iPhones. That's definitely the case in my household. And you know what happens? When one of us starts the car, while the other is connected to Bluetooth (Airpods, etc), the car instantly steals the connection. Super-annoying.

The solution seems so simple and obvious...Bluetooth needs an option, like wifi, where you can set whether to Connect Automatically, or not. Another approach would be a delayed connection. 

Optimized Baseball-Viewing

This past World Series, I perfected my baseball-viewing approach. Time is limited, baseball games just drag on too long. The obvious first, non-negotiable step to improved viewing, for all televised sports, is to watch on DVR. Skipping commercials, etc, cuts time drastically.

But modern baseball, more than the other big American sports, has long, boring stretches. Yes, if you are a really serious fan, maybe you want to watch each pitch of the prolonged, multi-pitcher duel. That's not me.

So what I do is leverage the YouTube TV "key plays" feature. I jump to the next key play. From there, I watch all the action. So if the key play is a double, then the next 3 batters are retired, that's what I see. So I do get plenty of the pitching drama, while saving a ton of time.

**********************

The one thing I don't like is that the software tells you how many total key plays there are--especially as you progress toward the end of the game, that can be a spoiler. The world continues to be insufficiently attuned to spoiler-avoidance.

I have no solution for futbol. If you took this approach, you would cut out 97% of the game. Futbol needs more scoring.

De Minimis Class Action - Make the Checks Worth Cashing

 I recently received this $3 check for my share of a class-action suit against Equifax. It is hardly worth the trouble it takes to cash it. Which I suspect is part of the whole, rotten, class-action game.

Here's a pro-consumer idea. Instead of sending 10 people a check for $3, have an internal lottery, and send 1 person a check for $30.

In other regulatory areas, there is the concept of a de minimis distribution amount. If the amount is so low that it is economically inefficient to distribute it to individuals, it goes instead to some alternative non-profit or regulatory recipient, with the idea that it will be put to good use, in alignment with remediation of the offense. I suppose, for all I know, that is what happens with un-cashed checks.

Order Body Parts Online and Save Big $$$

This is Part 1 of a two-parter. Part 1 lays out the facts of my consumer experience. Part 2 will have business commentary.

I hit a deer recently. Fatal for the deer, smashed up the passenger side of my front bumper cover. I have collision insurance coverage, so I filed a claim with my carrier, USAA. Because of the long wait at their preferred shop, I decided to use a local shop. I sent in photos, and USAA valued the repair at $1447. The local shop quoted me very nearly the same price (without knowing what the USAA estimate was).

However, they also told me that I could cut $1100 off the price if I could source my own bumper--e.g., find something used at a salvage yard. That's not the kind of thing you usually hear from a car repair place, but it certainly made a good impression. I think partly they are a good, honest, reputation-valuing local company, and partly the parts-finishing work is labor-intensive and tedious, and not their core value proposition, in this time of labor shortages. So they have to charge a lot for parts-finishing, and would be just as happy to forego that work.

I did some poking around the internet, and pretty quickly found MBI Auto. Reviews on their site were good, and there was also this very detailed this positive review of a prior MBI Auto customer, with many similar positive experiences by commenters. MBI's prices were absurdly low. $290, shipping included, if I was willing to let them ship the bumper folded, $450 not folded. I get why folded is cheaper (bumper covers are light but bulky), but while $450 is still a very good deal, that difference seems huge--I would have thought folding was worth maybe a ~$50 savings in shipping.

Anyway, I did some research, and it sounded like folded was a decent bet. Many people said it was 100% fine, worst case seemed like it would have a little crease and a crack in the paint. But seeing as this new bumper cover is going to be the shiniest part on an 8-year old vehicle, I wasn't after perfection at any cost. I know from prior experience that the key to affordable auto body repair is not going after perfection--85-98% perfect will often cost 1/3 as much as 100%.

The cover arrived super-fast, faster than promised, a mere 5 days from when I placed the order (the local shop would have taken longer!). It was carefully packed, and took some doing to unfold it (they include instructions). Leaving it in a warm, preferably sunny, room for a few days is part of the program.

No issues with the product quality. I even asked the local body shop if they thought the part was sub-standard in any way, and they said no, perfectly fine. So by sourcing from MBI Auto, I cut my parts cost from $1000 to $300. Quite a savings.

Dabbling with Home Automation

TL;DR

Kasa smart plugs and light switches work well and are very affordable. If you are curious about home automation, you can experiment with little effort and at a cost of $15-$100. The plugs are super-simple, the light-switches require very basic electrical wiring competency.

More

I've begun dabbling with home automation, mostly for lighting. I have purchased the Kasa EP25 smart plugs (4 for $40) and Kasa Smart light switches (<$30) that are well-reviewed by Wirecutter.

One of the light switches is motion-sensitive. I'm still fine-tuning it, but seems to work well. In hindsight, I would say if you think there is any possibility you want motion-detection, get it, because it doesn't cost much more, and you can turn it off if you don't want it.

Setup of the smart plugs was reasonably easy. The hardest thing is the fact that they only operate on 2.4 Ghz wifi, and require the setup device (smartphone) to be on the same band. Since phones will generally default to 5.0 Ghz, this requires going into your router control panel (not hard, but you may not remember how to access it or the password), and temporarily turning off 5.0 Ghz (don't forget to turn it back on).

Installation of the switches was not hard, and I rarely do electrical work. There is one gotcha, which is the volume of the plug is>> than a dumb plug, and you may have a hard time jamming it all back in the box.  I'm sure a pro could manage it, perhaps by trimming excess ground and neutral, but I wasn't up for that. After some searching, I came up with a pretty good work-around: these $5 box extenders.

The Kasa app is pretty good, and the plugs, though not the switches, are HomeKit-compatible.

My #1 need was to provide good & reliable wall-switch illumination of rooms that didn't have overhead lighting. Each room had the typical (1) switch-controlled outlet. So that takes care of one light, and doesn't require any smart stuff to work as expected. That was important, I don't want an over-complicated home where a guest can't turn on a light without installing an app. Then the other lights in the room are connected to a smart plug, which is triggered to go on with the smart switch. All works well, albeit with a ~3-second latency of the additional light to go on.

I also automated the fan in our bedroom that provides "white noise". It is on the floor in the corner, and my aging back dislikes stooping to turn it on and off. So I put it on a timer that corresponds to bedtime + 1 hour.

Similarly, I have a foot-warming carpet in my office that I also have to stoop to turn on. And that I sometimes forget to turn off. So I hooked that up to a smart plug, and put a turn-off schedule for the end of my workday, in case I forget.

Our Christmas tree lights are also very inconvenient to reach, so those also went on a timer (though given they are LED, I think the energy savings is negligible). On that note, these plugs include energy monitors. It is mildly interesting to see how much energy different appliances consume.

Last, I have a Corsi-Rosenthal fan setup in the basement, where the cat lives. I like to run that a couple of hours a day, not for cooling but for filtering. That was easy to put on a schedule

So that's it for implementation experience so far. In the process, I did quite a bit of research--much more than was needed for my relatively straightforward use cases--so I will document that next.

Apple & Subscriptions

I hate the fact that Apple rakes in up to 30% of subscriptions through the app. BUT--they sure do make it easy to monitor and cancel. I routinely check my subscriptions (mostly for streaming services), and set calendar reminders for when I need to cancel. Or if you are pretty sure you just need the one month already subscribed, you can proactively cancel, and you get the service till the end of what you have paid for(!) Quite a breath of fresh air in that regard.

Here's a feature idea: save me the manual step of the calendar entry--let me set reminders tied to subscriptions, by clicking on the subscription. (For extra credit--this is asking a lot probably--create calendar entries as reminders.)

I want a smart light switch that has up/down positioning

I don't live alone. It is absolutely critical that when a person stumbles into a room, when they fumble on the wall to flick the light switch, they get the expected illumination. The smart behavior can't get in the way of that.

Many of the smart switches, including the Kasa ones, don't work this way. They have a push interface that toggles between on and off. But you have no way, just by looking at the switch, to know which is on and which is off. 

This can be made to work nearly the way I want, replicating dumb switches. I simply connect the switch's ON and OFF states to the "toggle lights" scene. So the user who hits the switch to change the state of the lights gets what they expect. But it is still less elegant, and slightly less obvious, than if UP meant ON and DOWN meant OFF.

One counter-argument is that the state of the switch can become inconsistent, if the lights are turned OFF, say, via a smart app. To me, the solution is that toggling the switch DOWN and back UP will solve this problem. That is probably the most natural thing to do anyway. 

Another alternative would be to extend the behavior of the 3-pole dumb switch (2 switches controlling the same light). UP and DOWN don't necessarily correspond to state, but flipping the switch guarantees a toggle. The problematic detail here is what to do if state is mixed, for multiple connected lights.

Business idea: Customized service to notify a fan it is worth watching the game

Recording sports and watching them on my own time & terms is transformational. I think I would watch 90% less sports if I had to suffer through them in real-time.

I am also very much in the anti-spoilers camp. I know not everybody has the same viewpoint, but I am hardcore about it. The downside, though, is you lose the flexibility of entirely skipping a worthless game.

I can imagine a service that uses a combination of machine-learning and user-configuration parameters to notify a user if a given game is worth watching on the DVR. The user could set various parameters such as:

• My team wins (I personally don't include this one, but some people do).
• The score is close at the end.
• The score is close most of the game.
• The game involves a reasonable amount of scoring.
• The scoring is not all on penalty kicks (I'm looking at you, futbol) or home runs (baseball).

Also, the result wouldn't be a pure yes-no, although that would be an option. There would be an overall rating underneath the yes-no. So if you are me, a spoiler hater, you might want just the yes-no, because the score could give something away. But if you are on the fence or particularly busy, maybe you want an indication if it is a really good game, not just good enough to be a generally enjoyable watch.

Then there are all kinds of ways you could incorporate statistical and machine-learning elements, to adjust the rating. Just scratching the surface:

• Higher rating if many other people with profiles similar to yours rated the game highly.
• Lower the rating if you identify that you accidentally found out the result (lower still if you know the score).
• Use ML to adjust the rating based on your own ratings of past games.

Then also enhanced features such as telling you how far to skip ahead, or to skip to the last few minutes.

Email feature Flag R for reply expected

Sometimes when you send an email, you definitely expect a reply. But people's email habits being what they are, said reply does not always arrive. Google actually tries to use AI to remind you of emails that seem like they need a reply but haven't. That's nice, as far as it goes. I would like email to have a feature where you can set a "Reply Expected" flag.

Some E-Commerce Apps Should Be More Careful About Default Stores

Over the years, I have had a few cases where online apps wind up placing my order at the wrong location. I can't universally rule out user error on my part, but I have some clear-cut cases where the app messed up. In one case (can't remember now which app), when I identified my use case as In-Store Pickup, and an item was not available in my default store, but was available in a nearby store, it auto-switched my order to the nearby store. 

Recently with Panera, the app had a flat-out bug.

Either way, I wonder if more thoughtful preference configuration could help. What jumps to mind is asking the customer to identify which use case best describes their needs:

1. I almost always order for the same location. If an order is ever different than my default location, please ask me to confirm.

1. I order for many different locations. Do not ask me to confirm when the location changes or is new.

For extra-credit, AI could probably be brought to bear, to refine the options, or to default them.

Google Calendar Feature Idea: Filter Recurring

 I tend to use Google calendar for a lot of recurring reminders (renew drivers license, perform monthly maintenance tasks, etc, etc). I would like a UI affordance to toggle my view to show All - Recurring Only - Non-Recurring Only.

Central Mexico Trip Report

My wife, adult son and I just returned from a teriffic 11-day vacation in Mexico. Not beach Mexico, but historic, central Mexico. 6 days in Mexico City, 5 days in Morelia--an old, colonial city 4 hours west of Mexico City. We would never have chosen this vacation, if not for the opportunity to visit old friends, who were living in Morelia for 4 months, while on university sabbatical. But are we ever glad we discovered the delights of central Mexico!

First thing nobody told me about is the climate. I vaguely knew Mexico City was at a high elevation, but I never put two and two together. I dumbly looked at a map, thought to myself southern Texas is really hot, Mexico City is way south of that, it must be a blazing inferno. What a misconception! The mile-high elevation means it is very temperate, all year round. Think Hawaii or San Diego, except maybe a bit more comfortable--75-78F and very dry.

The next recalibration I had to make was the Mexico City environment. I absorbed the idea, 25+ years ago, that Mexico City air quality was horrendous. I think that was true, but like LA, it has improved a lot. It isn't great, but it also isn't a smoggy hell-hole. Most days we were there the weather app rated it "acceptable".

It was also very clean for a large city. The various street vendors were always sweeping up in their downtime. Compares favorably to US cities.

Now on to the question of security and safety. We have all read the chilling tales of drug-cartel violence haunting Mexico. It is real, but it is confined to certain areas, mostly near the border. Mexico City and Morelia both seemed very safe. I am sure there are dangerous areas of Mexico City, just as there are in Chicago, but no reason to go near them as a tourist.

Cost-of-living is very favorable for rich-country tourists. We stayed in the expensive part of the biggest city in Mexico, and overall costs were maybe one-third what they would be in the US (granted, the current exchange rate of nearly 20:1 is historically favorable). 

We spoke zero Spanish, and unquestionably stood out as gringos (being of mostly northern European ancestry, and some of us being pretty tall). Nevertheless, the people were very friendly, especially by megacity standards. 

Finding English-speaking service workers was spotty, a bit more than I might have guessed. Google Translate was indispensable. Get familiar with it before you leave, and download the Spanish language pack for offline translation.

We did not even think of renting a car. In Mexico City, like Manhattan, a car is the last thing you want. Uber is as reliable as in the US, and costs maybe one-third as much. For traveling between cities, there are extremely nice first-class buses. A four-hour trip to Morelia cost $33, and the bus was shiny, new and very comfortable.

Credit cards are widely accepted. Not quite as universally as current day in the US, maybe the way it was 10 years ago (i.e., cabs and street vendors don't tend to have Stripe swipers). So you will want to carry some cash. Including 5 pesos for public toilets.

Also, on the subject of currency, be aware they use the $ symbol to denote cost in Mexican pesos. Given the exchange rate while we were there, that meant dividing by ~20.

Bottom-line, central Mexico is a vastly under-rated tourist destination. It would also be an amazing place to snowbird. Or if so inclined, even to fully retire to.

Induction ranges should have one conventional electrical burner

Induction burners are the future of stovetops. One thing that causes consumer resistance is the concern that all your cookware has to be replaced. In many cases, that concern is overblown. But to ease the transition, it could be helpful to equip the induction stove with one conventional burner.

I guess one downside is that consumers will become accustomed to the cooktop instantly cooling, and may have a mishap with the conventional burner that remains hot (hopefully not actually touching it, but maybe placing a heat-sensitive item over it).

Cut tree stumps off below ground?

Is it really worth the cost of grinding away a stump? Can't you just cut it off good and low, and then do something creative with it?

Idiomwatch: Begs the Question

In modern usage, "begs the question" is "misused" more often than used in its correct/traditional meaning. Until recently, I was among the guilty. I, too, believed it means "begs (for) the question (to be posed)." I came to know that was incorrect (though I still think it has a lot of merit and utility). But I still did not realize the correct definition. I thought the real definition was "begs (off) the question", though I see now that doesn't quite fit, since begging off is active, versus passively trying to avoid the question. Wikipedia does note this usage.

The Wikipedia examples of the logical fallacy are not usages I commonly see.

Reminder Feature for Google Calendar

When receiving notifications (especially email notifications), include an option for "terminate any more notifications for this event". 

When I was in my teens, I picked up the idea of  "triple redundancy" as the NASA standard for fail-safe systems. The idea being, your backup also has a backup, so a catastrophic failure would require 3 (hopefully) independent things to fail at the same time. Without litigating whether this was actually a NASA design principle, or whether a more apt description is "triple failure, double redundancy, I can say the concept of redundancy made an impression on my youthful self.

Think about losing or misplacing your car keys. If you lose track of your primary key one day a month (1/30), adding a backup key takes that to once in 3 years (1/30^2). Add another backup, and you are at something like once over an entire lifetime (1/30^3 = 1/27000). And that is ignoring the fact that, once down to your second backup, you are probably going to be really, really careful.

Anyway, this week I experienced a rare quadruple redundancy failure--this time related to housekeys, not car keys.

We are having our siding replaced, so the garage keypad was removed (and resting inside the garage, where the workers left it). I idly noted that, as I walked out the garage, and walked to my car. What was I getting in the car to do? I was going to drop it off for service, and bike home. So that took out another source of access, when I returned home (via bicycle--that is how I minimize the pain of vehicle drop-offs)--no garage door remote. 

But I have never been one to rely on the garage for access, since if the power goes out (relatively more likely), or the opening system has a problem (even less likely), you are SOL. I keep a housekey on our keychains. BUT, we have a new car, and I haven't installed the housekey yet.

Still, I wasn't worried, because I also have a Tailwind smart garage door opener. I can easily open the garage door from my phone. Except it was this night my Tailwind chose to fail me (I think because of a required update). So had my wife not been at home, I would have experienced 4 system failures, resulting in lockout.

(I have since placed the keypad on the back deck, as a temporary backup, until the siding work is done.)

Inflation's Distorting Effects on Taxation of Interest

We've been in the era of 2% inflation so long that many of the distortions it causes have faded from memory. While reading up on iBonds, I remembered one of them: taxes are assessed against total returns, not real returns.

High-inflation example: 

• Inflation is 8%
• Your aggregate marginal tax rate is 32%
• You earn 10% interest (2 points above inflation)

So your after-tax yield is 6.8%--somewhat below inflation, so you are not even quite preserving your capital.

Low-inflation example:

• Inflation is 2%
• Same aggregate marginal tax rate of 32%
• You earn 4% (2 points above inflation)

Your after-tax yield 2.76%--somewhat above inflation.

Ordering Wine online Vivino

TL;DR

• I placed 2 orders to Vivino, for 8 bottles per order, each a mix of 2 different wines.
• There were under-$20 wines reviewed in the New York Times, and hard/impossible to find in St. Paul, MN.
• The retail price was competitive with the price listed in the article. Shipping was free. One order evaded sales tax.
• The delivery arrived promptly and was fully satisfactory.
• My cursory investigation suggests that buying directly from the distributor, to cut out Vivino's "middleman" profits, is not an option.

My (Limited) Experience

I've used Vivino (the wine rating/discovery app) lightly for a few years. I am a wine-lover but a dabbler.  I am not building a cellar and have a modest budget ($15-20 a bottle), so I really haven't gotten that much value out of the app, in terms of curation and discovery (and like many others, I consider the ratings nearly worthless, being crowd-sourced and utterly un-calibrated).

I finally got around to using Vivino to actually order wine, and I think that might wind up being my most valuable Vivino use case. I will frequently read some article in the general press--sometimes New York Times, sometimes the local paper--reviewing and recommending wines in my price range. I'm often curious to try what is recommended. The problem is finding it. The NYT stuff is almost impossible to find locally. And even the local stuff may only be available in a wine shop across town. That's way too much friction.

So recently I ran though a NYT article with recommendations. Of the 10 I looked for, I successfully found 4 on Vivino. Not bad. The prices were competitive, if not especially a bargain--never less, sometimes 5-10% more, than mentioned in the article.

Where Vivino shines is reasonable shipping cost. It appears that for < 9 bottles, they charge $15 flat rate. That actually isn't bad, for say 6 bottles. But it seems like there is a tipping point, I believe at the odd number of 9, where shipping becomes free. That makes Vivino a very convenient, price-competitive way to try and obtain wines that are not locally available.

And here's the thing--while Vivino doesn't support pure mix-and-match to get free shipping, it also doesn't have to be 9 bottles of the same wine. The way it seems to work is that Vivino has relationships with a number distributors. I don't know what that number is, exactly, but the same few kept coming up in my query vs the NYT list.

I don't have enough data to know if each distributor has their own requirements, but the two that fulfilled my order both seemed to set 9 as a breakpoint. As far as I could tell, any 9 bottles from that shipper could be combined to get the good price. I split my orders 4-5.

Both my shipments arrived promptly enough--4-5 business days--and were accurate. Very well-packed.

Comments About Vivino on Reddit

On Reddit, I have seen comments that put Vivino in the same category as DoorDash, and claim that they take a 15-20% cut. Given the competitive prices, I don't see how there is room for that much margin. But as a consumer, I am sympathetic to the idea that the aggregator should not eat the lion's share of the profits; I make sure to subscribe to anything I can directly, not through the Apple store.

So what I found interesting was that Vivino was absolutely transparent about who the distributor was. I looked up one of them on the web (Corkery Wine & Spirits). The price on their website was the same as Vivino, but then I noticed that they warned they only ship to 3 states (MN not one of them). I found this very curious, so I called them. I explained my situation, and they confirmed they only ship to those 3 states under their own name, but through Vivino they can ship elsewhere. I didn't try asking for a fuller explanation.

(The distributor for one of my two orders didn't charge tax for my state, giving Vivino an additional cost edge. I do not feel that this kind of online tax avoidance evasion is ethical or fair, so I don't consider this a pro for Vivino, but others may feel differently.)

Vivino vs Wine.com

Some Redditors speak more favorably of Wine.com, since they maintain inventory, rather than acting purely as a middleman. From the perspective of supporting your local wine ship, I don't see how this makes a difference. From the purpose of economic efficiency, I believe--for a highly fragmented market such as fine wine--maintaining inventory is unlikely to deliver net economic efficiency, and is instead a source of overhead and inventory limitations. The longstanding dream of online wine sales, after all, is to be able to buy any wine you hear of, for a price comparable to the normal brick-and-mortar retail price that prevails in its traditional physical distribution footprint.

In my limited experience with Wine.com, I found their inventory hit-and-miss, with a roughly similar hit-rate to Vivino (keep in mind, sample size with both is very small) . But I found their prices consistently on the high side--15-20% more than the typical retail price.

And that is before shipping. I haven't used Wine.com in a few years, so I did some quick investigation. It looks like their shipping price for 6 bottles is about $4.50 per--nearly double Vivino's $2.50. At 12 bottles, the per-bottle price decreases to about $3.25. It seems to very slowly decrease with volume from there. But clearly they are going for the Amazon Prime approach, by offering a $60 annual fee to get free shipping. Which is not a bad deal. 

Venmo Feature: Advanced Functionality for Splitting the Bill

Venmo has a split-the-bill feature, where the user can assign payment amounts. It's a good start. But a common use case is multiple people go to a restaurant, one person pays, and the payor doesn't know who ordered what. The basic functionality I would like to see:

• Attach a copy of the bill.
• Enter a total amount, invoke the split request.
• Each user examines the bill, calculates their share of the base bill. Venmo apportions tax & tip.
• Venmo keeps track of the total reimbursements received.
• Venmo provides reminders for parties who haven't responded.

Advanced functionality:

• If total is off by more than a set amount (e.g., 10%, above or below), Venmo notifies all users.
• Venmo scans receipt, and lets users click on their line-items.

I. Hate. Organized. Gambling.

Alarming and depressing article on the explosive arrival of app-based sports betting. I hate organized gambling. I hate it intellectually--it is the triumph of hope over math. I hate it aesthetically--the trappings of gambling, from garish smoke-filled casinos to grimy OTBs to convenience store lottery lines--is soul-crushing. I hate its social effects. And now, also hate it for overshadowing the sporting events themselves.

Keyless Entry Strategy for iOS or Android

I recently installed a Tailwind iQ3 smart garage door opener. It is very impressive, pretty simple to install, and downright cheap at $60. Just the fact that it will alert you if the door is left open at night, and if desired, will automatically close the door, if probably worth the price.

It also eliminates the need for a keypad. In my experience, keypads are a hassle and a bit of security risk. Because the code is typically very hard to change, people don't change it often, or use the temporary code feature. 

You can open the door remotely, which comes in handy in various situations, such as your neighbor wants to borrow some tool in the garage when you are away on vacation. Even better, you can assign opening privileges to other Tailwind app users. Great for guests, or families with more than 2-3 garage users, who would otherwise need to obtain extra garage door modules for their car.

Which brings me to my main point. While the sharing privileges feature is great, it comes with the substantial friction of each guest user having to install and provision the Tailwind app. It would be SO much better if this were nearly frictionless--i.e., if it were built into the mobile OS.

(Note: I know that a garage-oriented view of home access is a very suburb-centric viewpoint. There is a clear analog with smart door locks, more on that in a moment.)

Apple or Google should acquire Tailwind, and partner with the lock industry, to build keyless entry access-sharing into the OS. 

Apple is probably the more obvious candidate, at least in the US. If this were an Apple-only feature (think iMessage), it provides a distinct source of competitive advantage and lock-in through network-effect. Given that households in the US that have garage doors, and can afford smart locks skews upper-income, this fits well with Apple's customer base. Moreover, Apple's good image regarding security in general should transfer well to this use case.

I think the immediate first step is acquiring Tailwind (who I believe is the market leader, certainly the functional leader), and making it Apple-only going forward. The smart garage door market is new enough that I think that a play for total dominance is realistic.

The door lock market is much more established and fragmented. It also has a heavy decorative dimension. So I am doubtful that a total domination play is viable. Instead, Apple could move quickly, and leverage domination of the smart garage market, to establish its standard, open for adoption by heterogenous door lock manufacturers.  

******************

NOTES

As a consumer, I would ideally prefer to see an industry standard. But from the perspective of business strategy, it seems like a great opportunity for Apple. Also, I am doubtful about the standards-based approach happening any time soon.

A consumers should never rely solely on anything electrical, let alone "smart", for critical access. I cringe when I talk to someone whose only access to their house if via the garage door opener. So always carry a housekey--that applies to smart locks as well. But for many use cases, you can tolerate the pretty low risk of an electrical outage. E.g., if you have a weekly housecleaner for 10 years, and there is a 25% probability that once over those 10 years, the power will be out, and they won't be able to get in--that doesn't seem like a crisis (unless of course Murphy's Law strikes, and it happens to be the day before you are planning a big house party!).

My Original Covid "Modeling"

I recently came across some back-of-the-envelope modeling I did early in the Covid ordeal (05/18/2020). Conclusion was that the duration of "Flatten the Curve" was a theoretical minimum of 214 days. I didn't even bother posting it at the time, because it seemed to depressing.

The core assumption underlying the model was that a large percentage of the population was going to get Covid, it was only a question of when (my working figure was 60%). Then the next key metric requiring an assumption was--what proportion of Covid patients would require hospitalization? My guess at the time was 10%. This turned out to be way too high (by a factor ~5X), although per this paper, I think that was a figure that was circulating at the time.

Anyway, from there it was just a matter of calculating how many "inventory turns" of hospital beds would be required to cycle the entire Covid population through, and how long an inventory turn required (on average). My guess for duration (5 days), turned out to be very low, so partially offsets the high guess for proportion of population infected.

Keep in mind that 214 days is the theoretical best. It assumes the rate of Covid sickness is perfectly optimized, never exceeding hospital capacity (which would imply excess deaths), but never leaving any slack (to ensure the shortest possible duration).

Optimization is always hard, but optimizing rate of acquisition of a novel disease is impossible. So the real-world outcome probably would have been both excess deaths, and still a duration of longer than 214 days. That is, if the 10% of Covid patients require hospitalization assumption had been accurate. Thankfully that was not the case.

0.0028	Hospital beds per capita
0.5	% devoted to Covid patients
0.0014	Steady-state hospital beds
0.60	proportion of population who gets Covid
0.10	proportion of sick requiring hospitalization
0.06	Proportion of population requiring hospitalization at some point
42.9	"Turns" of beds, to cover entire hospitalized population
5	Duration of hospitalization

I Can't Help It, I Hate the Placebo Effect

I know it is wrong, but in my heart of hearts, I detest the placebo effect. I prefer a world without this kind of statistically noisy pseudo-magic. So I take guilty pleasure in reading this article, which casts doubt on the belief, developed over the last 70 years, that the placebo effect can be an important clinical tool.

The "open placebo" stuff, especially, is hard for a devout rationalist to stomach.

The reason it is a guilty pleasure is because, also in my heart of hearts, I know that I should applaud anything that helps. If placebos and open placebos improve clinical outcomes and reduce suffering, that is a good thing.

Comments on Crypto

I'm a hardcore crypto skeptic, borderline hater. Regarding digital currencies, such as Bitcoin and Ethereum, I don't see what real problem they are solving--outside of enabling criminal activity in general, and ransomware spectacularly. 

My impression is that many of the proponents fall into 2 or 3 camps. One camp is the promoters--they have something to sell. Maybe because they are also a believer (Camp 2), often because they are a huckster. Another camp is the deep believers. These seem to be libertarian types, who have some very deep-seated dislike of any form of centralization. They see currency independence a crucial step in some form of idealized, Atlas Shrugged-ish elimination of the need for individuals to have any need for government. Then the third camp are speculators. They see the meteoric rise of crypto and are drawn in by the justifications. The difference between the deep believer camp is that the financial payoff is what gets their attention; the belief follows.

So there is another strike against cryptocurrency--the company it keeps.

There are a number of crypto supporters who jump in to say that the tech is about much more than currencies. But I never hear even vaguely convincing examples(1). People talk about smart contracts, but they seem very vague, it isn't clear to me how they practically improve on "dumb" contracts (other than the satisfaction of removing a "middleman", even if that doesn't save money or have any tangible benefit), and it seems like they assume away the enforcement problem.

Then there are NFTs! The first time I read about them, I thought it was an elaborate tech in-joke. NFTs are screaming "The Emperor Has No Clothes"--setting aside extreme niche, hobbyist uses, that could probably also be accomplished with traditional commercial centralization (e.g., being able to prove were an early backer of some Indie artist). 

I've listened to podcasts on the topics, to see if I can find out what I am missing, and they usually just convince me more. I should admit, I am at some risk of "motivated reasoning", especially regarding NFTs, because their promoters talk about creating "digitial scarcity". As if scarcity can be a social good! I hate scarcity, I want abundance!!!!

Service to Facilitate Cash Offers for Houses

NPR had an interesting story on a trend where companies enable consumers to make cash offers for houses, rather than having a mortgage-approval contingency. This makes their offer more appealing to the seller, since it reduces risk. Even with a pre-approval, many things can go wrong. My mother was a real estate agent, and as a youth, hearing her stories of deals falling through due to a buyer's buyer's buyer failing to qualify for a mortgage, I often wondered that the whole system didn't wind up in gridlock. Cash offers do eliminate that problem.

I'm not sure what to think. When I evaluate a new business process innovation, I want it to make the overall system more efficient. Usually, that means taking cost out of the system. For instance, mortgage securitization adds an extra step in the process (packaging the loans), but those transaction costs are outweighed by the efficiency of capital allocation (no geographic disconnects between mortgage demand, and funds available to lend).

The question the interviewer should have asked, but didn't, is what is the net additional cost to the buyer, to get the backing of the company that "fronts" them the cash?

I can think of ways this might add efficiency. One source of efficiency is simply compressing the time-to-closing (another benefit of cash offers). The longer the time-to-closing, it could be more likely there are inefficiencies such as temporary housing, temporary storage, or the pending sale house standing empty. It's not completely obvious though--closing too fast could bring complications of its own. Of course, just because you make a cash offer doesn't mean you have to close fast--the cash buyer could offer the seller flexibility, fast or slow, whatever they want. So it seems like there is surely some efficiency there.

 The existing mortgage underwriting process is cumbersome and time-consuming. So maybe there is some efficiency through vertical integration and better sharing of information? Maybe the cash sponsor is adding value as a trusted advisor (that part in the NPR story about not letting the customer offer more than they think the house is worth).

Make Congressional Representatives Less Parochial

A few years ago, this idea came to me that the US, collectively, might get a better Congress if it were less parochial. My proposal was that some fraction of Congress should be elected by randomly assigned national constituencies.

I have a refinement, or alternative, to that idea. I would like to see some fraction of each member to be elected by a randomly assigned national constituency. Off the top of my head, 20% national constituency seems like a good number.

That would preserve local representation, while introducing a national constituency large enough to be a powerful tie-breaker.

Viruses do not necessarily evolve to be milder story

Zeynep: Viruses do not necessarily evolve to be milder...Evolution is not a teleological process, bad match for a story-telling species' brain. Things seem to make sense—the just-so story...

The whole thread is right-on, but as someone whose bete noir is the human weakness for a good story, I love the second sentence. 

Adoption of e-Delivery for Documents

Companies would like customers to opt for e-Delivery of bills, statements and other documents. It saves the company a non-trivial amount of money, and is environmentally beneficial. 

Sometimes a user concern is that they will lose access to the account, perhaps because they (unwisely) chose a work email address (don't get me started). Or the e-Delivery notifications will go into their spam folder. Or they are just bad at email.

I can think of a good mitigation. If a consumer hasn't accessed a company's online portal in, say, 6 months, that should trigger a paper delivery of the next document (bill, monthly statement). Included in the paper document should be an explanation, and the option to convert to paper by scanning a QR code. That also might be used as a way to regain access to their online account, in the event that is the problem (subject to security considerations). 

The remote-controlled assassination of Fakhrizadeh marks a scary precedent

While I don't mourn the death of a top Iranian nuclear weapons scientist on the merits, the manner of his death is deeply troubling. Mohsen Fakhrizadeh was assassinated by a remote-controlled, AI-assisted machine gun. It was undoubtedly a given that such an event would happen sooner or later, but it is nevertheless a horrifying precedent.

The advent of remote control assassinations is the immediate concern, and that is plenty bad enough. But imagine what kind of carnage could occur if one, or a few, of those were let loose in a crowded public assembly?

I always assumed respiratory viruses were primarily airborne

Must have been a case of being right by dumb luck, but my mental model of respiratory viruses (influenza, colds) was that they were primarily transmitted by inhaling particles in the air--not by having projectile droplets land on your facial orifices.

 

Tournament Codenames

I love the board game Codenames. The online version is even better, because you can add your own words. However, I have ideas for a more intense version of the game.

The normal game is a ton of fun, but the fun mostly comes just from the guessing. There are limited tactics and very little strategy. Often the margin of victory is decided by a single turn.

My solution is to make the guessing process richer. Typically in my experience, 2 word guesses dominate. I would like to see more 3's, and even the occasional 4. But the way the standard Codenames works, that is nearly impossible. So here are the changes I would make:

Expand to a 6x6 grid

This will give substantially more opportunity for finding multiple connections.

Eliminate 1 Strike You're Out

To encourage guessing higher numbers, and to counteract the increased chance for false matches that will come with more cards in the grid, tweak the rules to allow the turn to continue after a wrong guess. I think some experimentation will be necessary to find the ideal. I toyed with the idea of 1 wrong neutral guess being allowed, but I am thinking maybe it should be just 1 wrong guess (after all, a wrong guess that exposes the other teams card is worse than a neutral). It would be prohibited to guess more answers than remaining cards (e.g. if your team has 3 cards and other team has 6, you can't guess 5 to get extra bites at the apple, you can only guess 3 or lower).

In conjunction, I would eliminate the "continuation guess" that is currently allowed, if you don't successfully use all guesses from a prior turn.

Possibly Decrease the Number of Neutral Cards

I'm not sure about this one, but something to consider--will draw out the gameplay, allowing strategy and superior play to accumulate in a clear victory, rather than chance and which team happened to go first.

I am calling my proposed version "Tournament Codenames".
