UK expands Online Safety Bill to criminalize encouraging self harm
The biggest problem with UB, as interpreted by C/C++ compilers is the unfounded belief that the spec says that you can assume any path that leads to UB is defacto incorrect and can be ignored. That's the bogus logic required for steps 13-16 to be true.

That interpretation of the specification language is clearly bogus as that means more or less all C and C++ programs can be compiled to a single return instruction - when compiler devs introduced this new new interpretation of UB, it turned out they had to then go through and add a bunch of exceptions for basics like memset, memcpy, and memmove could work without falling afoul of their invented nonsense.
Makes sense.

One thought is, if the OS/libc was designed so that exec() always created a child process, then you could get the same functionality as fork() by creating a child process using exec() and passing along just the info that the child process needed, possibly using IPC. This seems like better encapsulation, for the same reason you wouldn't write a function which required a ton of arguments it didn't use. It also makes the issue of forking a multithreaded process irrelevant.

But I could imagine this approach being slow if there's a lot of state you want to pass, if copying entire pages of memory (the way fork does?) is significantly faster than than sending the same data via IPC.

I wonder what the most common non-exec() use of fork() is.

> Exactly. The goal is to broaden the hiring pool. Some companies are limiting their hiring pool to people close to the people already on board, their old-boys network, or to people who look like they'd fit in.

what a weird rationalization. So these companies purposefully hire someone they deem better for whatever reason and the EU decides for them that they are wrong. This has to go badly, the EU via a continent-wide policy does not in fact know better than the individual entrepreneur. To deny this is a wild theory to say the least. Also the hiring pool right now was: Everyone. Now the new mandated policy is actually limiting the pool in specific circumstances depending on who already works there. Weird how casually people choose to distort truth.
>The US owes its status as a superpower primarily to most of Europe wearing itself out in the two world wars.

Sure, but US did not start WW1 or WW2, but European powers did. In fact, US were mostly neutral for a long time in both wars, only entering last minute. Don't forget that European powers also tried to capitalize on the US civil war way back when. It's just business, nothing personal.

The EU cold have also been better prepared for this by investing more into local defense and energy sector starving Russia of any leverage.

But EU chose instead to rely on idealistic hippie dreams by halting nuclear development, lowering defense spending and suckling on the sweet Russian gas teat, letting its former leaders become highly paid lobbyists for Russian oil and gas companies when their terms were over. The situation the EU finds itself in is entirely of its own making, like that meme with the cyclist who shoves a stick in the front wheel of his bicycle while he rides it and then blames someone else for his fall. The US is not at fault here, in fact, they even warned the EU several times of over reliance on Russia for energy and Germany scoffed it off. And I say this as an European.

EU needs to snap back to reality and get its act together tackling pressing issues (Russia, China, energy, debt, housing, tech, environment, illegal migration) based on what's happening in the real world around them, not based on some hippie ideologies of the far left who live in Cloud Cuckoo Land.
They can't, because one of several YouTube competitors (Dailymotion, Vimeo, DTube, Twitch, etc...) would replace them and not force logins.

YouTube is about the content creators, and people and advertisers will go, where they are at. So if there is a mass exodus of content creators and users, YouTube is pretty much finished.

Exactly, some things are probably UB at compile time, these IMHO should by default be a compile time error.

Integer overflow is harder ofc.
> gcc screwing the developer over because it was UB when they thought it was just implementation defined

No, the developer thought "UB" produced an integer with an undefined (but still valid integral?) value. They misunderstood what UB is, not whether or not something was UB.
This is exactly why so many of us a vehemently opposed to squashing. But in case you still have the original refs for the PR you can run bisect on that to narrow it down - assuming that the individual commits are (somewhat) consistent states that can be built.

Github isn't really the issue here, because it offers the tools to make this differentiation. Maintainers just have to use it. At Github, you can use issue templates that have a set of pre-defined questions and add labels to the created issues.

Example from my own project: https://github.com/Kovah/LinkAce/tree/main/.github/ISSUE_TEM...

Users can only create bugs and have to answer some detailed questions, because I really don't want to deal with "XYZ is not working"-types of issues without any context or further information. Feature requests are redirected to the discussion forums first. It works very well for me.

While, I’ve been collecting useful one-liners for some time, there was always friction to apply them: search my notes, copy, paste, edit, etc.

As of recently, I finally landed on a solution I feel very comfortable with:

- Write templated one-liners (could be longer scripts too), automatically replacing which files to apply them to.

- Wrap the one-liners with a tiny elisp function with a meaningful name.

- From Emacs, I can now easily apply these wonderful one-liners to either the current file or a list of them, without having to remember details nor tweak the commands. Fuzzy searching to apply commands works great.

GitHub wikis are already accessible over Git in a separate repo, as advertised via the “Clone this wiki locally” sidebar link: e.g. the wiki at https://github.com/swaywm/sway/wiki can be cloned from https://github.com/swaywm/sway.wiki.

(Of course, people have also made a variety of Git-based Web authoring tools spanning from CMSes to wikis, but I can’t say I’ve seen one that really worked out—Git’s capabilities seem too powerful to be tamed in a reasonable Web-based editor. The most elegant way to link from a website to its Git version history that I’ve seen is on Yannik Sander’s blog[1].)

> 14. Okay, but if the line with UB is unreachable (dead) code, then it's as if the UB wasn't there.

This one came as a surprise to me. Is this really (unconditionally) true? And if so, why? Seems trivial to me to ensure that UB that will never under any circumstance execute will not affect the functioning of an otherwise correct program.
It is not just America. The whole west is failing in differing ways, to differing degrees, and at different states; but the heading is generally the same. This is also just the start of a lagging problem. It’s civilizational cancer or HIV, not a laceration or broken bone. The whole immune system is unable to detect what is killing the body, let alone act against the threat to its existence. By the time it is obvious to the naive and short sighted that there is a problem, things will long have been terminal.
> We know that people tend to recruit people they "fit" with.

I have a really hard time seeing this as a bad thing. Recruiting people you fit with is a requirement for you to be able to work with them. And there are already laws in place that you can't define "fit with" as not being a woman, a person of color, etc.

Let people hire who they want (discrimination based on sex, race, religion, etc, not included) and if they don't hire optimally their company will be out-competed by another company who does.

The vaccines in use in China are already highly effective. The best data on this comes from Hong Kong, which uses both Pfizer/Biontech and Sinovac. Three doses of either vaccine is roughly equally effective at preventing death.

The problem isn't what vaccines they're using. The problem is that many old people don't want to get vaccinated, period.
It's apocalyptic when there's basically no immunity in a population (no prior infection and sub-par vaccination) and you have a variant that's 10x more transmissible than the original. Think of what happens when it rips through 1B+ people at the same time (think early pandemic NYC, but 10x worse). You'd end up with 1% of the population dying over the span of a month or so. That's not a desirable outcome...

Yes but what "knowledge" would be relevant at this stage? The virus has been through multiple rounds of mutation and has been well-studied. The amount of things that are a) possible to discern before it was released c) a surprise to the scientific community and c) is still applicable feels like it would be very small - barring sci-fi scenarios.

The challenge is not about getting better vaccines, but actually pushing vaccines to the older population.

The goal of a corporation is to make profit, that's all the shareholders care about. To suggest that they're hiring sub-optimal candidates, just to hire one gender over another, is a bit far-fetched.

But that's actually very likely to happen if gender discrimination is mandated by law.
The polio vaccine is different though. First it is not a mrna vaccine, second it is ~100% efficient in case of 3 doses.

In the example you've provided, it looks like the town has benefited from the money launderer buying the property, didn't it? The bad actor was the previous owner, who "wiggled through the system" (i.e. both the town and the guy were corrupt). The new owner may have been a bad guy in other parts of the world, but didn't have the connections in this town, and didn't know what strings to pull. The town condemned the house, which ended up being taken over buy some good guys, so happy end.

Did I get the story right?
Twitter in general.

I never really liked it due to the 250 character limit (used to be 150) and people insisting that it is possible to have a meaningful discussion within this limitation. Sure, you can split your post into multiple messages but the design of the site encourages short responses so no real discussion will be happening.
That's from the spec POV. On x86 for example, signed int overflow is well defined.
In the very broad sense, yes. Progress is not linear and civilizations ebb and flow. Even the Greeks had their own “dark ages” for example. Perhaps we are entering a down trend again (who knows?) but enlightened ages will spring forth again too.

I'm pretty certain that that is not true. There is no study I've seen that correlates (either positive or negative) susceptibility to COVID with general health.

Except that it may not, unless you know what you are doing and press the right button:

> With the monitor or viewfinder, you may see an image with an aperture that differs from the shooting result. Since the blurring of a subject changes if the aperture is changed, the blurriness of the actual picture will differ from the image you were viewing prior to shooting.

> While you press and hold the key to which you assigned the [Aperture Preview] function, the aperture is stepped down to the set aperture value and you can check the blurriness prior to shooting.

> In the same vein, you probably don't need to learn about flash guide numbers when modern continuous LED illumination covers 99% of use cases without any guesswork.

And leaving your camera in "auto" also probably "covers 99% of use cases without any guesswork"… but you give up creative control to the software. Why bother learning what aperture is at all if 99% of the time you won't ever matter to taking a photo?

The whole point of reducing the use of "auto" is to make creative choices yourself.

This doesn't make any sense; the vaccine confers immunity.

In the US, that would be inviting an age discrimination lawsuit. It's admitting that the company preferentially hires young people (which is illegal), and implying that older people wouldn't "fit in" and would thus be discriminated against.
What about the reverse osmosis filters many homes have?
Haha. It does not work that way. You have no control over recommendations or the effectiveness of the advertising it is designed to optimise.

The problem with "tech" companies is not simply advertising. It is control. If the user cedes control of their computer to the "tech" company, then the company may use it for advertising. But the user has no control over how the company exercises its control. There are no legal limits. The use being made of the computer is ultimately for the benefit of the company, not the user.

The company decides what to show the user. Given the monpolistic nature of how these companies operate, e.g., "tech" proponents will argue YouTube has no viable alternatives, if the user is not satisfied, then it's tough apples.

The company might decide the user is a sub-optimal target for advertising. Then what. This could affect what the user is sent as "recommendations".

The issue is one of control. Under the "tech" company model of computer and internet use, the user gives away control. In return, she gets "convenience". She can be passive and consume what is chosen for her, but there is no guarantee of satisfaction. The system is designed to benefit the company.

There seems an unnecessary presumption that this means 4/5th of the work hours, with an implication of 4/5ths of the output.

But a 4 day week can also be four 9 hour days. So long as management adjusts daily expectations to match, there's no need to expect lower productivity, or to demand a salary cut.

Overall though it's a fairly open secret that, especially in big companies, you can set a 40hr work week, but you're not getting 40hrs of actual work from them. And for some jobs this is just beyond people's fatigue limits anyway.

To hazard a guess, for in-office, the average would likely be around 25 to 30 hours. The rest goes into the ping pong table, chatting, morning coffee, reading HN etc.

So there's plenty of margin to lower scheduled hours and raise expectations during those hours. There's also plenty of room to give 3 days of rest in exchange for 4 days all-hands-on-deck.
Both "UB" and "IB" are terms defined in the language standards, and it's obvious that's what we're talking about here.

x86 defines what specific instructions do, nothing so crass as "signed integer overflow" - that's part of why the language standard has to define it as such.
I'm in Industrial Automation (drives and power electronics) and none of the PLC guys here use C, all ladder, sometimes ST. The B&R Acopos Test Rigs that I've built with a B&R PLC do steer towards C for the logic program (Automation studio 2.x). TBH, if I did have to do any PLC programming I'd rather use C than most of the IEC languages. Personally I love C, although I can see the advantages of Python and C++ for tools etc.
That's irrelevant. A C compiler targetting x86 has no obligation at all to handle signed integer overflow in the same way the processor natively does. Because it is not an assembler - it is compiling against the theoretical C virtual machine.

This is for the same sort of reason that unsigned overflow does have a well defined meaning in C, and will always do exactly that even for targets that do not natively do that (if necessary it would emulate that behaviour in software).
> It's even worse than that; hazard ratio increases significantly with each re-infection
https://www.nature.com/articles/s41591-022-02051-3

I don’t think this paper is a great source for that idea - the ratio of people with one infection (440,000) to people with three or more infections (1,000) is so different that I wonder if demographics or behavioral characteristics differ between the groups.

Empirically, their conclusion can’t really be true or each COVID-wave would be worse than the preceding one
It is undefined behaviour if I write GCC --hlep

Well no, it's a compilation error, you need at the very least a semicolon after hlep and from there on it depends on what GCC is. If it's a function you need parentheses around --hlep, if it's a type you need to remove the --, if it's a variable you need to put a semicolon after it,...

Because GCC is all-caps I'm guessing it's a macro, so here's an example of how you could write it (though it won't be UB): https://godbolt.org/z/dYMddrTjj
And to be useful they would have to be infected over the time the vaccine is effective to build longer-lasting immunity instead of losing the vaccine effectiveness over time completely, no? (Just a guess, I'm no expert.)
