Railroads have nearly universally lost money on the dining car. In the 1880s they did it because it was a loss leader - people choose the train (vs carriage) for the nice meals - something they could do that the other travel options could not (it isn't clear if this made a difference but they thought it did).

Station meals make far more sense in general - there is a lot more space to work with. You can also put multiple options (rent space to different restaurants) in a station. The only downside of this is you need enough flex so that people can get off when hungry eat and get on a different train (meaning both empty seats for them and multiple train options). Still trains have different economics from airplanes and should attempt to run no more than 70% full.
Oh no, 'climbing the greasy pole' takes at least three generations. The 'right neighbourhood' is itself a complicated concept, because the working and middle classes in the UK live cheek-by-jowl. I live in a street of rundown Victorian working-class houses that are so close to each other and the street that everyone has net curtains in their windows to stop passers-by from seeing in, but from my bedroom window I can see into the back gardens of the comfortable 1930s middle-class houses in the next street, which have leafy front gardens to provide privacy. As for schools, much of the middle-middle class and all of the upper-middle and upper class pay fees to educate their children at private schools, some of which charge more than a software engineer's salary in annual fees.
They could in theory but I'm dubious governments will be willing to shape their customs enforcement to accommodate this company. Best case I think they might be able to do a drop off at a place for customs inspections and pick them up again with a different craft once cleared.
Honestly, learning things and doing projects together brings memories too. If that wasn't the case, your family was doing it wrong.

Plenty of kids jam together in a garage, have awesome memories from the school band, or otherwise. Great memories are formed. Or sitting around a camp fire playing a harmonica or a guitar.

If you're learning "instead of" rather than "as a means to," well, there's your problem.
Fun fact, you cant set your microwave to 100 seconds.
The notifications feature sounds similar to what iOS 18 will have. Maybe you'll like it -- https://www.engagelab.com/blog/ios-18-priority-notifications. I find this better than having to manage your notification settings manually. With so many apps it'd be hard to keep the config up to date.

The second idea sounds very similar to just setting strict time limits to an app. I guess the hard part is finding a kind of limit that works for everyone.
The distances are so great and the duration + resources that it takes to cover that distance with high function and accuracy is so ridiculous, that it ends up being pointless to attempt it. Intelligent life expires long before it spreads widely.

The answer to Fermi is that there's no point to expanse, which culls the effort given enough time (the exploration effort is very expensive in exchange for rapidly diminishing returns for most civilizations). Intelligent life that makes it to our stage and beyond chooses to go inward long before it spreads super wide outward. There is vast, unlimited, easy, lower cost satisfaction inward (virtual space), there is nothing of great value outward at any reasonable cost of resources and time (humanity doesn't grasp this widely yet, it's still in the naive, neighborhood exploration stages). The only thing out there is disappointment, once you discover it's almost all low value repetition (extraordinarily vast repetition of very low value entities).

> I asked a few recruiters this question and was really disappointed that none of them were interested in placing a group (even just 2 developers) together.

Have you seen a recruitment agreement/contract? They're usually standardized to focus on hiring individuals, with specific roles, at a certain rate/method of payment. They want to send your resume to more than one client - how many companies want to hire a pair of people and would enter into a contract to conduct that search? Probably zero. Recruiters can lose their fee if the hires quit/fired before a certain date. What if only 1/2 or 1/3 worked out? Hiring a group would be complicated from the recruiters perspective, not worth the risk. They don't get paid unless they make the hire.

Imo, the group/pair should approach the CTO/CEO or engineering leadership and do negotiates that way instead. Recruiters take a hefty chunk of $$ and if you're trying to "market" yourself, going thru a recruiter is less professional as a small squad vs direct business development.
Your comment is quite confusing.

The observation is that the "take take take" behavior arises out of a sort of survival-of-the-fittest mechanism. Both preceding comments seem to lament this, rather than relate to it.

If you look at the history of the NAACP trying to fight legal discrimination, one of the things they were quite focused on was ensuring that the cases involved people who are as clean as possible. The messenger matters as much as the message does; the more imperfect the messenger it is, the more it allows those against the message to turn the conversation from the message to the messenger.

Stallman, even without the stuff mentioned here, was already a pretty poor choice for messenger. His tendency to focus on semantic nitpicking gave his arguments a kind of tedious quality to them (GNU/Linux, anyone?). The outspoken political views can turn off people who are not politically aligned. And he's always given off this sort of skeevy vibe to me personally--and that sentiment has seemed to be shared by lots of other people. Long before any of the stuff being complained about here happened!

The negative influence of Stallman isn't purely theoretical anymore. We now have a couple of stories of people saying that he made them personally uncomfortable with unwanted seemingly sexual advances. Apparently, these have continued after being explicitly told by several people to knock it off. Several organizations have suspended their funding and involvement with the FSF over his reinstatement. Whatever you think of the accuracy of the accusations against him, the general perception of him is clearly negative, and to be frank, it doesn't seem like he brings any positive qualities that would make letting him go be a tough call (consider Elon Musk, who is obviously a pretty effective salesman for the future and props up Tesla's share price even as his outspoken political views are causing real problems for his companies).

"Who needs extra buttons labelled things like 'Kids Meals', 'Healthy Cooking', or 'Snack'? What does that even mean?"
I've used the Braun wrist cuff, and while the heart-level feature is cool and perhaps good enough to mitigate position issues, I found that it was very unreliable vs. cuff measurements.

What do I mean by "unreliable"? Two things - (1) internally consistency for the given device and (2) not closely correlated to the arm cuff measurements.

My method: I would wear both devices and take a series of readings (like 5+ from each in a session, and did multiple sessions a day).

My results: while the cuff readings of course had some minor variation in of themselves, they were largely consistent with themselves (i.e. clustered around the average for the session) whereas the properly-positioned (according to the heart height feature) wrist measurements were all over the place showing big swings between readings and a wider dispersion from the mean.

Then there was the issue of did the wrist average measurements roughly correlate to the cuff averages - and not only was the answer "no", it would vary whether it was higher or lower. Which is a shame - it's ok if it was, say, overstating things by +5 mmHg but overstating at that rate consistently (because then you could mentally adjust the outputs); but when it's inconsistent you're just left scratching your head.

As I wrote about in another thread, the continuous wrist monitor Aktiia that I've been trying gets correlated explicitly to an arm cuff and seems far, far more accurate and consistent than this Braun device. It uses optical imaging of your wrist's blood vessels vs. physical pressure on a cuff.

All this to say - test for yourselves! Try multiple arm cuffs, even. While the exact numbers are less important than the trend, you need a device that you can trust w.r.t. output.
Yes, I meant PRC :)

I think those companies increased efficiency, which in general makes things better as long as there is sufficient competition in their markets... Sadly governments have failed in stopping them from hovering up startups and like. So now they in many cases have too much power.
The render thread is running an infinite loop. You need to manually drain the autorelease pool, otherwise autoreleased objects created during rendering won't be released until the thread exits (there's an implicit top-level pool in each NSThread which is drained on exit). In UIKit/AppKit, the autorelease pool is drained at the end of each NSRunLoop iteration by the framework, so you don't typically drain it yourself. Here they created their own runloop - an infinite `while` loop that calls `onRender()` - so they must drain the pool themselves.

The book uses Tk (via Python's tkinter library) for the first 10 chapters and then switches to Skia, which is used by maybe all of the browsers now (I believe Webkit on Linux just switched to it from Cairo). It seems to be by far the most common high-performance 2D graphics library.
I always hear that geometry shaders are slow. Why are they slow?
Nurses/healthcare professionals often take the patient's blood pressure and heart rate just as soon as they enter the room after walking and moving about. Wait a few minutes and the measurement changes significantly, giving you a better indication of actual heart rate at rest.
Microservices quite likely, but I'd expect browsers to get ~zero benefit from KSM; aren't browsers all thin-copy forked from a single process anyways?

And yes I sort of agree with swapping unused stuff so you have more room for cache, but that's only good for unused stuff; if you swap the programs you're actually running - even just zram swap - you're going to hurt performance.

How Dwarf Works: Debug Information Entries
You already can with X11, for example running your rogue graphical program inside a graphical virtual machine. The vm gui will filter-out the events that happen outside the window and the rogue program will think it's running alone.

It's nice that wayland makes such containerization much lighter, at least concerning the GUI (you still need to hide your filesystem, network, etc if you want to run rogue programs under wayland). But I don't see the point in enforcing it for each and every one of your programs. It's extremely unergonomic.
And the standard is CRLF, so you're either following the standard or using a mix.

they did acknowledge some alternatives, but I agree more discussion would have been nice.

FTA - Option 3: Using other existing REPL implementations: The authors looked at several alternatives like IPython, bpython, ptpython, and xonsh. While all the above are impressive projects, in the end PyREPL was chosen for its combination of maturity, feature set, and lack of additional dependencies. Another key factor was the alignment with PyPy’s implementation.
It’s not that scale ruins everything, it’s the pursuit of scale that ruins everything.

I have thought a lot about antitrust recently and realized that it’s an overlapping problem with the VC unicorn problem. People get so hung up with being bigger/biggest, faster/fastest, that they minimize or ignore pathological side effects.

What if we have a progressive tax structure on business based on scale? Partly on size, partly on market power?

For example, what if corporate income tax were tied to the logarithm of the number of employees+contractors? What if the corporate income tax increased with the market share in markets served?

These kind of ideas have very low impact at small scales, but after a certain scale they start to have such a huge effect on bottom line that they disincentive growth for its own sake.

And they’re self-regulating and largely objective, unlike our current antitrust laws in the US.

Firefox Flatpak has neither write or read permission to your home directory. At least that's my take from browsing file:///home/myuser. If you try to open or save a file using the native dialogs, you do grant the appropriate permission on demand, but that's using the xdg portal, outside the app scope, specifically designed for this.
Is the performance hit sorted yet when opening a page? For me Firefox used to hang for a second or two doing something? Just a blank screen with the progress bar paused around 20% or so and apparently nothing happening...(DNS? HTTPS handshake?) and then it would kick off and load normally. Happened on mobile(android) and desktop(windows, Linux, macros).

On chrome-based browsers the same pages on the same computers on the same network would load in within the blink of an eye, with no pause.

I eventually gave up and went back to chrome after Firefox being my daily for years. I prefer the dev tools in chrome anyway TBH

Yes, I was thinking the same. If everyone is measuring heart rate under similar conditions, and then correlating that heart rate with other factors, is that perhaps alright? Can we factor out the "error" to get a working baseline, even if the measurement isn't really heart rate at rest?

I doubt it, frankly. No one is controlling for these conditions. The easiest thing you can do is to wait a few minutes for the patient to relax after entering the examination room to get a reading at rest.
That's awful.

Reminds me of the Dutch childcare benefits scandal [0], where 26,000 families were unfairly labeled as having committed tax fraud (11,000 of which had been targeted via "risk profiling", as they had dual nationalities [1]). Bad policy + automation = disaster. The wikipedia article doesn't fully explain how some automated decisions were made (e.g. You had a typo in a form, therefore all previous benefits were clawed-back; if you owe more than €3.000,- then you're a fraudster and if you called to ask for clarification they wouldn't help you — you're officially labeled a fraudster, you see).

Edit: couldn't find a source for my last statement, but I remember hearing it in an episode of the great Dutch News podcast. I'll see if I can find it.
