A shop I worked in ages ago had a mainframe on site supporting lots of batched transactions over the course of a 24 hour period, along with the daily operations for a 35 facility logistics company, spread throughout the southeastern United States. They had a staff of 8 mainframers that ran the entire operation. All of the PCs onsite (my area of responsibility) were basically 3270 terminal clients for z/OS.

Sometime later, a connection on LinkedIn pointed out the following resources:

Also, mainframes are really good at high throughput transactional jobs. That's why you see them in banks, transportation, insurance, etc. Big Tech™ doesn't see it as "cool" and are too focused on the Next Big Thing™, so there's not a lot of attention there. Sometimes, boring just gets the job done.
Yeah, Eye-Fi (the company) doesn't exist anymore, probably because newer cameras all have wifi. But for a photobooth at a party that needs to run unattended, it's better to use an old camera you don't care about too much ;-)

Having gphoto monitor the camera constantly (my first attempt) is not a good solution, because if for whatever reason the connection to the camera is lost, gphoto just dies.

In my current setup, gphoto downloads new files at regular intervals (via cron), puts them in a directory on the pi, which is then rsynced to a server. This is very resilient: it survives rebooting the pi, turning the camera off or on, etc., with zero intervention. All it needs is a network connection to the Pi (wifi or ethernet) and nothing else. No app, no phone nearby, no bluetooth, no nothing ;-)

I use an old Pi 3 for this that's plenty fast; it would probably work on a zero (but I've never been able to buy one) or other single boards. Ideally it could be put in a small box that could be mounted on the flash shoe and that would also act as a remote...

I believe a minimalistic server framework (Flask) is an unfair comparison to what the author is complaining about, namely packages that need to integrate into an entire front end framework and ecosystem (React Native). Handling requests (Flask's primary use case) is but a small fraction, and addition to, all of the other things you need to implement and consider on devices that would run React Native.

Examples: camera roll and / or camera integration, contact listing, deep linking _into_ the app, linking _out of_ the app, foreground or background push notification display (and subsequent routing on press), the list goes on and on. IMO, native development, even if you choose to go Kotlin / Swift path instead of react native, is extremely complex.

To be brutally honest, I too can fire up a linux box or container, install flask, and have my simple REST server up in a matter of minutes. The same cannot be said for all the example native features listed above.

A good portion of the mechanical wear and tear on an engine comes from starting/stopping it.
Have you considered that most people really do not give a shit? I would much rather drive a "deathtrap" that doesn't break in 5 years than a "safe eco friendly :)" car that charges me 12 grand a year to accelerate.
Maybe I'm missing something but they look slightly out of proportion and somewhat bland. Not awful but I wouldn't bet the house on this just yet...

The future is going to be a mish-mash of the past?
> My car, for instance, turns off the engine when stopped, that can't be good for the engine and battery.

It's largely irrelevant.

More than half of the wear and tear in an engine happens during cold starts. Unless you're in utter gridlock, you won't experience them more often than when at the start of the trip.

Toyota's hybrids turn the engine off and on on a regular basis, even during cruising, and have a proven track record of reliability.
This reminds me of Linus Torvalds Subsurface project: https://subsurface-divelog.org/

Unfortunately I don't have enough domain knowledge to do a comparison.
I'm someone who is indeed struggling to find a job, and in my case salary has little to do with it since so far I've been filtered before that's been an issue. There's actually no way to compete on price even if I wanted to, since employers are looking for luxury goods and offering to work for very cheap would send the wrong signal. I understand the market is very different if you have a great resume and everything is lined up.

So I think a lower volume in the hiring thread has a stronger impact on people who are struggling, since they necessarily need to apply to a high number of places, compared to the impact on people who are going to get multiple competitive offers regardless.
Defender maybe?
You almost stumbled across the reason Toyotas are so prevalent in the third world but you missed it because it doesn't fit your biases.

A running vehicle is a hot commodity in that part of the world and with cheap labor they can fix just about anything.
So why was that Mitsubishi not fixed and running? Why is every other car in Brazil a Ford? Why do you pretty much never see a Hilux in Russia (much to the consternation of the fanboys who think it would fit well in a rural country like that)?

Supply chain.

Toyota does not make seals. They do not make bearings. They do not forge and roll their own steel. They buy the same parts everyone else in the business does. Toyota was the only major brand to pay the poor equatorial nations any attention for a long time. They were the only ones who did the hard work to establish the business relationships needed to get their service parts into the poor parts of the world. As a result of this their vehicles are the preference of the poor parts of the world, because they are the ones you can actually get the parts for.

I think it's pretty clearly feasible in the specific example GP gave, since -fwrapv does this for GCC and clang. In principle it should be do-able from code level with e.g. 'pragma gcc optimize("frapv")' (but the gcc docs for this say that this feature is for debugging only and doesn't always work).

Taiwan is worth ending the world over. Not because Taiwan is particularly important by itself, but because expansionist dictators must be stopped at all costs. If Xi succeeds in conquering Taiwan then that would be just the first of many targets.

From a game theory perspective, being willing to end the world over Taiwan is ironically the best way to prevent the world from ending. Deterrence works.

> I sometimes come across stationary cars with a running engine, and I honestly wonder why anyone does that.

As someone who frequents very warm countries, I think most people do it because of the AC. If the engine is not on, the AC won't adjust the temperature that you've selected.
I agree. One has to ask: what is worse for the environment, a car that pollutes more but lasts 400k miles or a car that pollutes less but only lasts 200k. The cost and environmental affects of manufacturing aren't zero.
Yep, that's the big drawback. It looks rather nice, however.

Lisa Miura, Hawaii County’s real property tax administrator provided these answers:

The government does not claim ownership of all land covered by lava; the private property owner retains title even as the land’s assessed value plummets to zero.

As for that new oceanfront land? The state claims new coastal land created by volcanic eruptions. This ownership applies to lava flows extending seaward from the coastline — increasing the size of Hawaii island — not to those that cover the existing property.

There may be cases where the government eventually assumes control of private land inundated by lava, but it is not common practice. “If the property is abandoned, then eventually it could be sold at tax sale. However, we have not had a tax sale recently in this area as the values have been less than what was owed on taxes. The county and state have not been automatically assuming ownership,” Miura said in an interview with the Honolulu Star-Advertiser.

The government does not claim ownership of all land covered by lava; the private property owner retains title even as the land’s assessed value plummets to zero.

According to the county, Hawaii County does reduce or eliminate real property taxes for property owners within a lava inundation zone, and is doing so for those devastated by Kilauea’s current eruption, which has destroyed more than 500 homes in Lower Puna, Kapoho and Vacationland at this point, and made many more inaccessible.

How much is the assessed land value for fresh lava? The assessed value of the property would fall to zero for 2018, and the owner would pay no property tax, according to Miura. Any property assessed at $500 or less is exempt from property taxes, under a Hawaii County law approved last year. Presumably, such properties would continue to be assessed at $500 or less for years to come. And then, like some homeowners in Kalapana, rebuilding could begin for those residents willing to take the risk again.

Tips from GitHub, Vol 1: Customer Service Is King (2017)
I was talking about the average on average. IRL twitch streams, Jinny 6k viewers, CookSux 2-3k viewers, jaystreazy 2k viewers, robcdee 4k viewers.
Bonnierabbit does one stream every now and then 10k. Amouranth literally does nothing, streams from home and lately "dating" streams, 7k low 16k usually. Japandyjones now that he's in Tokyo 1.5k viewers. Jakenbake in Tokyo 6k.

If you're a woman in a mostly younger male audience platform you get the viewers. All you need is an attractive body and a nice dress.

Ibabyrainbow 21 year old wearing braces showing off her body 1.5k viewers.

I'm not into ASMR but holy crap licking microphones for "the ASMR" where the girls are dressed in tight dresses with perfect make up, where you can guess that the microphone is really a penis replacement. 100% female domain.
How many want to see a guy licking a microphone? 5% most likely with the odd spike for curiosity.

I'm saying on average the females have it easier to attract viewers, that is also the traditional female field. You don't have to provide content, your body is content.
Idk if you have noticed that women mostly like to film themselves on stream because they know that the males watch them for their looks. Male cameras are mostly turned away from them filming their surroundings.

As a male streamer you need special equipment, at least so they think, so you can stream in 1920×1080 with redundant modem and sim card setup, while female streamers don't bother with the weight and just use a 720p smartphone.

There are of course always exceptions and I don't claim to be an expert. I've only been watching this field since this summer and those are my observations
cold starting, actually.

Oil is viscous. It takes time for it to flow down.
Exactly. Ketamine as a "party drug" is more something taken "to get f*cked up" rather than "to feel good." I've always found it odd that it caught on as a party drug, TBH. It's likely more to do with availability.
TBH I think the answer is really quite simple and also fairly nihilistic: It's incredibly unlikely that you will personally be able to find the full truth in anything, even wildly important things like the justification of a war.

At the same time, the reason why the war justification is so notable is because it was eventually brought to light, and its unusualness of the lie made it notable enough for reporters to believe people need to hear about it.

It makes sense to me to generally conclude: liars happen, but generally dishonesty isn't something that's considered moral/ethical by society. Most people don't bald-faced lie about stuff, when they do its considered a scandal. Generally people will honestly tell some truth of what they understand from their own incomplete knowledge and that's about as good as you're going to get (there is no "objective truth").

Trustworthiness then becomes people who knowingly lie less often relative to others, or people who source their truths less often from known liars. For example, I don't believe Alex Jones on much of anything given that he's knowingly lied repeatedly, extensively, and built his career on it. But Joe Rogan I'm pretty sure just sources from liars more often than I'd like in his claims, so I don't really listen to him either. I'm more likely to believe the Slate Star Codex guy, because I don't think he knowingly lies about his analysis but he has his own biases and blindspots and so I generally don't believe what he concludes when he says things that correspond to his blindspots.

That is cool. I assume that it has been tested and certified. Dive computers are critical safety gear. You really don't want them crashing on you.
I suspect a lot of mainframe development today is Java EE centered, for which there is an abundance of stuff on the web.

During my vocational training, I did a bit of work with mainframes and found a forum back then I liked, but my work (and the forum) was mostly about sysadmin-stuff, and the little coding I did was in Perl.

There is a sizable library of RedBooks on IBM's web site somewhere, but again, the stuff I was interested in was about system administration.

A lot of the culture in the mainframe world developed a long time ago, and in relative isolation from the rest of the IT world, so I suspect by the time Stack Overflow became popular, their communities had already found other ways and places to mingle and pass knowledge on and around.

With hardware, software, and support contract being so expensive, and corporate culture being what it is, I also suspect the threshold to call up the the vendor for support instead of Stack Overflow is much lower than in most other areas.

(Most of this is speculation on my part, I only spend a few months in this fascinating corner of IT. If I'm wrong, I'd love to hear to from someone with actual experience.)

Indeed, personalized advertising to match your psychological profile as much as possible, with just the right incentives/brain-hijacking. Then, why not just do this for all "ads" for all industries (politics is one of the most aggressive currently), and, then, why not all information one is exposed to? Let's get extreme, and look at the diplomacy-playing CICERO, that can employ strategic reasoning for how to best shape ads for you.

I would go one step farther: The documentation will say it is undefined behavior but the compiler doesn't have to. Here's an example from the man page for sprintf

sprintf(buf, "%s some further text", buf);

If you miss that section of the manual, your code may work, leading you to think the behavior is defined.

Then you will have interesting arguments with other programmers about what exactly is undefined behavior, e.g. what happens for

sprintf(buf, "%d %d", f(i), i++);

Apple Watch Ultra has a water resistance rating of 100 meters under ISO standard 22810.

Apple Watch Ultra may be used for recreational scuba diving (with a compatible third-party app from the App Store) to 40 meters, and for high-speed water sports.

Apple Watch Ultra should not be used for diving below 40 meters. Water resistance is not a permanent condition and can diminish over time. For additional information, see support.apple.com/en-us/HT205000.

I don't disagree in an abstract, but the issue I have is with an argument that relies on 'obvious' as a flag. Not everything is obvious ( and most things could be argued ). In fact, some things may appear obvious only to be lost in the sea of nuance. This is the reason I object to arguing along the lines of obviousness. North Korea and Sweden are very different countries in just about every way I can think of. It would take a tremendous stretch of language ( and rather ignorant audience ) to convincingly argue that Sweden is just as oppressive. With America and China it is not as straightforward a comparison, because those countries do share some interesting characteristics so less of a stretch is needed.

The issue gets muddled, however because the word lockdown is discussed without any nuance attached to it. In US, it was challenged in courts and people ( clearly ) mostly did what they wanted to do ( that said, some businesses got fined heavily ) despite heavy media shaming, whereas in China lockdowns included stories ( among others ) of sealing off entire buildings without allowing their denizens for any way out. Despite the same word, those two approaches are very different in application ( edit: and results ).

Even then the entry level full-frame cameras will shoot something like 10 photos per second in RAW which is usually sufficient for sports or motorsports photography. There is a compressed raw mode that's required to enable the fastest capture mode but when you get into more expensive cameras like the Sony A1, it can shoot full resolution (50 megapixel) raw with auto focus at 30 frames per second which is mind blowing. It costs $6,500 vs $2,000 for the A7Iv though so you're definitely paying for it.
If it’s been running safely for thirty five years, “deathtrap” seems an unwarranted epithet.
Diesel engines in particular, do not like being run under no load - it is far far better to have them switched off rather than running. Boat owners struggle with this when moored, as they can't charge their leisure batteries by just running the the engine without engaging the prop.

I don't know anyone with a stop/start engine that has ever complained to me about having to replace their battery sooner. Personally, I drive clunkers, and have never had to replace a battery on one of those, despite me turning off the engine whenever I can. I think modern batteries are pretty damn hardy.
That's why I said "falls under the hat of" :) I promise the talk is relevant.

`-fwrapv` is an attempt toward doing such a thing for signed integer overflow specifically. I bet it's a pain to maintain because it significantly increases the surface area of the compiler that needs to be tested.

I don't believe doing this for more cases is feasible at the level of the compiler. Things like CHERI where the hardware and OS help are much more viable, in my book: https://www.cl.cam.ac.uk/research/security/ctsrd/cheri/

As a general rule, most machines break during state changes like start/stop. Keeping an engine running means no piece is subjected to the extra acceleration of restarting and your starter isn't used.
