Well, at least I got this paper out finally: https://thephd.dev/_vendor/future_cxx/papers/C%20-%20Restartable%20and%20Non-Restartable%20Character%20Functions%20for%20Efficient%20Conversions.html

Once I finish it I hope to return to the C++ version in "Transcoding the world". It's just been too long of a journey.

the problem with telemetry in open-source applications is that the majority of people who use them don't tell anybody about their workflow, so whenever you change something, you have to be prepared for a sudden and unexpected inflow of angry complaints about you breaking something

you could do polls, but that selects for people who would complete a poll, again excluding many who would be touchy about their workflow

krans,
@krans@mastodon.me.uk avatar

@whitequark This problem is not exclusive to open source applications. Most of our customers would have a complete meltdown at the idea of providing us with even the most simple summary of their usage of our product.

We've had the discussion and there is absolutely no way that anyone will agree to give us the kind of detail in telemetry that would be required to remove dead features.

(Anyway, no-one will authorize any work on removing features, even if confident we could do it safely).

Researching nuclear weapons for my next #shadowrun scenario. Maybe i should use a VPN?

krans,
@krans@mastodon.me.uk avatar

@kyonshi What sort of nuclear weapon do you want to detect? As I understand it, even the most radioactive nuclear weapons would be a struggle to detect from a couple of rooms away (background radiation + inverse square law).

krans,
@krans@mastodon.me.uk avatar

@kyonshi Maybe. I think the W87 has a depleted uranium nosecone, which is very good at blocking nuclear radiation while not being very radioactive (half life is 4.5 Gy). Alpha radiation is very easily blocked by air. I reckon it would be easy for a W87 to be missed by a Geiger counter held immediately adjacent to a lorry at a checkpoint.

It's only about 250 kg, so unlikely to be detectable by looking at vehicle loading. Probably doesn't emit any EM radiation and it should be non-magnetic. ๐Ÿคท

@kyonshi Here's an wild idea: use artistic license and claim that the LX-17 / PBX-9502 explosives in the warhead produce detectable outgassing of their binder chemicals, that can be picked up close to a stationary vehicle with a handheld sniffer?

Ordered back to the office, top tech talent left instead, study finds

In the months following return-to-office mandates, an increased number of senior employees departed Apple, Microsoft and SpaceX, often to work for competitors.

Gosh, at that price, I sure hope they got all that unmeasurable spontaneous innovation that can only happen via ad hoc office encounters back! But I guess that can only be confirmed by the same gut feelings that lead to RTO in the first place.

hankg, to peloton

My first thought is that no good will come of Peloton being acquired by a private equity firm. More often than not it is a vampire operation: they suck the company dry, break it up for parts, and then pockets all the cash. Sometimes they can be productive but I can't assume that.

@looopTools is a massive success story for Rust. After multiple attempts to write a multi threaded style engine in C++, and getting completely destroyed by data races on each attempt, funded Rust , and then used it to write a high performance multi threaded styling engine () with no crashes or data races on basically the first attempt.

KathyReid, to stackoverflow

Like many other technologists, I gave my time and expertise for free to because the content was licensed CC-BY-SA - meaning that it was a public good. It brought me joy to help people figure out why their code wasn't working, or assist with a bug.

Now that a deal has been struck with to scrape all the questions and answers in Stack Overflow, to train models, like , without attribution to authors (as required under the CC-BY-SA license under which Stack Overflow content is licensed), to be sold back to us (the SA clause requires derivative works to be shared under the same license), I have issued a Data Deletion request to Stack Overflow to disassociate my username from my Stack Overflow username, and am closing my account, just like I did with Reddit, Inc.

https://policies.stackoverflow.co/data-request/

The data I helped create is going to be bundled in an and sold back to me.

In a single move, Stack Overflow has alienated its community - which is also its main source of competitive advantage, in exchange for token lucre.

Stack Exchange, Stack Overflow's former instantiation, used to fulfill a psychological contract - help others out when you can, for the expectation that others may in turn assist you in the future. Now it's not an exchange, it's .

Programmers now join artists and copywriters, whose works have been snaffled up to create solutions.

The silver lining I see is that once OpenAI creates LLMs that generate code - like Microsoft has done with Copilot on GitHub - where will they go to get help with the bugs that the generative AI models introduce, particularly, given the recent GitClear report, of the "downward pressure on code quality" caused by these tools?

While this is just one more example of , it's also a salient lesson for folks - if your community is your source of advantage, don't upset them.

@msquebanh Earthquake-resilient building standards are a good thing. I don't understand what point you're trying to make.

My number one wish from the fallout of the xz backdoor is that it kills autoconf/configure/autohell. That shit is illegible and watching for compile failure is a shitty way to test for features

krans,
@krans@mastodon.me.uk avatar

@craigtimpany Most compilers lie about what features they support. What's a better way to reliably test for compiler features than to test whether the compiler has those features?

krans,
@krans@mastodon.me.uk avatar

@waldi @craigtimpany Take the Microsoft C++ compiler, for example. They say they support certain features (e.g. no_unique_address) and set the __cpp_no_unique_address macro, but their implementation of this feature doesn't actually give zero-sized initial member variables unique addresses.

You can either program a big map for every C++ compiler ร— every feature for whether each works usably for your program, or write a compile test.
