> Perhaps try to give others a bit more benefit of the doubt.

I wonder whether you'd be willing to go into a meta-discussion on that, perhaps not public? I seem to hit this kind of stalemate too often and need someone's help to close the gap. I can see your email address in your profile.

I don't see how consistent and repeated "can't work" answers can lead to a collaboration on an actual solution. I'm not even the proposer of the optimization, but I can see it has merit and doesn't have high intrinsic complexity.

> always packing columns would turn an operation that doesn't currently rewrite into a rewriting operation

I don't think this is necessarily true. What is the operation that would rewrite that doesn't already, assuming the same shape of solutions already used?

> The per-row overhead would be too large - we already have problems with that.

I read this as "the proposal can't work because [...]", on another thing that feels like a technicality. There are likely all sorts of bit-packing and other options that would make the overhead low, and the Postgres per-row overhead is already so large that it seems doubtful that it'd be that big a deal.

(For example, if you've very few columns, you don't need much space for the counts, and if you've more columns, the extra space for a few sizes isn't going to have much impact. Also, any active transaction range isn't going to have a large number of table shapes in it, so rows could likely use a table-definition-version number in place of any column counts. Or you could probably look it up in some bookkeeping structure via xmin and drop the per-row details. The fast path would remain when there are no recent shape changes.)
The way this is phrased makes it sound unreasonably judgmental, all stick and no carrot. If anyone had spoken to me like this at 18 I'd have been furious. There's not a word of how you might help the kid be less of a hermit, lose less friends, find a job, take care of themselves. Just "some pressure". Who do you think is responsible for the kid being the way they are? Thanks for prefacing it with a warning, I'm wishing I hadn't disregarded it.
If the market were rational, I would agree with you.

But it is not, and Musk has a weird cult of personality around him.
> I suspect the massive money printing going on for years has had no impact because most of that money never actually landed in the hands of actual people and just existed to be sucked up by wall street and elites. And they dont spend in a way to impact prices.

Yes. I think we had something like monetary inflation but it was all captured by the upper 1% and 0.1%. The policies suppressed wages down the Ginni Coefficient ladder and actually contained inflation. This produced low interest rates due to low CPI inflation expectations. But it would up producing what economists call asset bubbles rather than inflation. This has also built up over the past 30-40 years ever since Volker in 1980, it goes way beyond the post-2008 recovery and the pandemic.

We're now seeing the point where this has all become unsustainable, and the masses are clamoring (rightly) to get a share of it. Either we're going to allow that inflation to run downhill now and re-price via inflating wages and suck up the smaller pain of inflation, or I think we're going to have to inflict truly severe economic pain of multiple deep recessions. Given how much people now deeply hate inflation, now that wage inflation has reached the baristas and food service people, it looks like we're going to choose recession.

Well their comment was actually interesting, had you read it.

It's one of the only ones so far, mentioning the fact of discussing with the 18 yo son, trying to find the cause(s) of his behavior.

Most of the other answers are as stupid a "blablabla when I was 18 I had a fulltime job", good for you Jake, it made you into the pretentious adult applying one solution to everyone else problems and even worse giving those advice randomly to people on in the internet.
Too bad the Nothing Phone doesn't have a headphone jack. I couldn't agree more.

For anyone else who won't even consider a phone without a jack... I'm much more excited for the upcoming Asus Zenphone 9, which is roughly Pixel 5 sized and slightly smaller than the standard iPhone size, and features a headphone jack! It's the smallest (and headphone jackiest) flagship in quite some time, slightly smaller than its predecessor.

Seems like all restaurants should charge an extra fee to delivery services they didn’t sign up for. If the policy for the driver is just to pay whatever then there is no crime here.

Restaurants use this extra fee to compensate for the bad reviews.

If the policy changes for the driver then a customer is screwed over with a canceled order, guess who gets the blame? The delivery service!
I doubt renewables are cheaper once they start making up a majority of the supply (except in small countries that can get most electricity from hydropower). Sure batteries or other storage technology may get there eventually but that's very much TBD.
Everything is a graph doesn't mean you can make a graph from other data structures, it means you have to make other data structures from a graph.

I go back and forth on the headphone jack debate. But the notification LED I just don't get. They aren't large and intrusive like a jack - so it's not space saving. I like to leave my phone on my desk and only check it if I see an LED blinking. Not constantly wake it up to see if I missed something. I assume most people want that?

I came to two possible conclusions - 1) it's about engagement, and for some reason companies want you opening your phone often, or 2) so many apps notify for everything anymore, the LED would just constantly blink. At least 2 could be solved by only allowing certain apps or classes of notification (like say, phone or text) notify the LED.
Supergiant games doesn't have a publisher, they publish it themselves so they can do whatever they want. I don't really consider them indie, to me "indie" is when the people developing it are also the people funding development, meaning people make choices without worrying about what others opinions.

As for self made engines, if you make it yourself then that is a risk. If you make it in unity or unreal then the publisher knows they can easily find people to help you ship it if there are problems, but for a self made engine it could be unsalvageable.

Pretty cool that you can determine the exact probability distribution for the digits of fraction expansion of a random real number:

lim_{n->inf} Pr[k_n = k] = -log_2(1 - 1/(k+1)^2)

And this was determine already in 1929! I think fraction expansions was all the rage back then.

I agree, I know it isn’t new with Microsoft, but they sure do consistently release slow buggy software. It would seem that a company as large of Microsoft could get ahead of the issue, but perhaps it their size and beurocracy actually make it harder to quality control.
I dunno, I think I explained my position, my reasoning, my priors, and came to a reasonable conclusion. I'm certainly not insisting I'm right. But what I know I can do is install a camera in a visible location and be open to people approaching me and asking for changes.

I liked this article, and I like the cleverness of the scheme. But I wish it had offered more of an explanation about the economics of delivery. He said his friend was just figuring it out: two years later, can he offer a reason for why Doordash can be losing so much money, other than a network of pizza arbitrageurs?

One thing that bothered me a little was the "fuck Doordash" mentality as an excuse for something which may not legally be stealing, but is ethically equivalent to it. I think "fuck X, they deserve it" is an excuse a lot of people use, but obviously it's still wrong even if you don't like your victim, or if you can get away with it.
Windows NT had a fairly complete POSIX subsystem (for the time) [0] (but not virtualization layer) so you’d only be able to use Linux if it could compile as a rump kernel (it can’t).

That was followed by a replacement subsystem, Windows Services for Unix [1], which later used a “real” Unix compatible layer after their purchase of Interix.

WSLv1 was therefore the fourth subsystem available (though it couldn’t do some of what the previous ones did, and did some of what they couldn’t), and the complete rewrite as WSLv2 is at least the fifth such attempt.

I have a non-Ring doorbell camera and while I can't prove it has deterred theft, it's pretty useful in at least:

* Getting a partial face/partial vehicle ID of someone who stole our package

* Seeing the sneaky method in which they stole the package (allowing me to talk to neighbors warning them about the method used)

* Getting a private instant announcement of who exactly is at the door (if they've been here before and they're in my contacts)

* Notifying us while on vacation that someone out of the ordinary is at the door (and being able to speak to them as if we were home)

* Deterring raccoons (bright light on the front of the camera)

Not-so-useful things:

* Seeing the large number of cars that like to use our driveway to make a U-turn

> APL, Algol60, ML, Smalltalk, Simula, Prolog, Perl, Ada, Erlang and Eiffel are all extremly influential languages that all modern languages

Of course. The reason I like Common Lisp is not because it has been influential. I like it because by my personal quality metric it got more things right than any other language currently in use.

> you can actually do it better the second time

Theoretically. But in practice all modern languages suck compared to CL with respect to my personal quality metric, which is that I want a language that imposes the minimal cognitive burden on me as a programmer. To me, making programming as easy as possible is the whole point of high level languages. If I were willing to work hard, I'd just write in assembly language.

There have been a few improvement on CL: T. Oaklisp. Dylan. But they have all sunk into obscurity.

> every single inspiration or language feature that is remotely related to lisp is "re-invention", with the additional implication that it's an inferior imitation.

Yeah, well, if the shoe fits. The only real innovation in programming languages since Common Lisp is static type inference.

> Ruby can redefine the base language from underneath you.

Yeah, that is not necessarily a good thing. Also, Ruby can't change its surface syntax. Common Lisp can.

Thanks for that. Having written a threaded interpreter before that immediately made sense. It does seem like you used some other hints to the compiler as well so this would fall under "experts only" type of code and that's OK. I still wonder how well good old "goto" might do, but once you move away from a huge switch/case to individual functions I can see how it might help a bit.

I still don't understand why some people seem to like the idea of iterating simpler things with recursion using a tail call.

For sure no. If you are storing a trove of copyrighted movies, revenge porn, or child porn then you would for sure not have it marked for public access. Google clearly doesn’t want their storage to be used for these nefarious purposes but anyone who has tried to train a ML algorithm knows, false positives is the name of the game so they should really only be used in places where false positives do little to no harm.

I understand your comment and I just want to say that my comment is assuming we're past that point that you're talking about. I didn't want to write an article. Some kids can be stubborn. Anecdote: My great grandma tried that with my great uncle (all carrot) and he lived in her basement playing videos games until he died of a heart attack. I thought he had the best life because he got to be lazy, but it didn't server him very well. The end. Being a pushover and being considerate is a very fine line that is easy to fuck up.
For the last 2 years that I've used teams on Linux it has had a constant issue, even across Pulseaudio and Pipewire. If a BT headset is connected when Teams starts it never shows up in the device list.

I always have to killall teams thrice, wait a while for some cache to expire , because otherwise I start Teams and it's still logged in for a few minutes and will disconnect the middle of a call just to logout, and THEN start teams.

And today was another nightmare, people complained about my mic quality, so I did a test call, sounded fine, killall teams thrice, restarted it, reconnected to meeting, sounds fine now. wtf...

And besides that today alone Teams malfunctioned in at least one other way I can't remember now.

So I love that Teams for Linux exists, but damn is it shit.

My co-worker in the same call today also runs Linux but he runs wired so he has no complaints.

The statements in this article may or may ot be true. What prevents me from engaging with the argument is that the right wing think tank universe always makes these claims, and yet always finds excuses for the blank check military budget. Its a little hard to take fiscal prudence seriously when the largest expenditure is considered sacrosanct. Secondly, these claims always vet louder during Democratic administrations. The most recent Republican administration spent (wasted) money and ran up significant debt and yet its only now that Cato wakes up? The timing is just too coincidental.

If your view of macroeconomics is essentially kitchen table "income < liabilities = trouble", fine, but at least be consistent.

I don't plan to let mine have their own cell phones (we'll probably get a dumbphone for them to share when they go out places or for their friends to call them, as they get a bit older) until they can pay for the phone and plan themselves. If they stop paying for the plan, I'll lock the MAC out of our wifi. Can't pay for it, not ready for it. 8 year olds shouldn't have a smartphone.

[EDIT] Just to back up your "if you can't pay for it, you don't get it" approach, that is. Strong agreement. Risky perks like Internet access must be earned. As for video games, the Switch is nice because you can easily physically remove it to somewhere else without having to unplug a bunch of stuff. Switch isn't there = no video games right now. Switch is there = video games are OK. Zero monitoring required.

There's not enough information here to help nor is there any leverage OP (or really the parents) could use to change their behaviour without threatening their relationship with the kid.

If it is an addiction like behaviour the person needs to see the negative impact their addiction has on their life and what they love before they are willing to change.

I bet this kid had free access to screens since they were very little.

Why doesn't this kid have a job? Why doesn't the kid have a social life or other responsibilities that takes them outside? Are they special needs, physically or mentally? Are they being solely supported by their parents?
