Interesting. Is this a full system and not just a board? This is still not quite clear to me. Hopefully, one of these systems gets produced in such large quantities that there's some pressure to add mainline Linux support.

Long before GenAI, I saw people using meme generators a lot in corporate presentations. I found that equally jarring. Replacing that with GenAI stuff is probably an improvement. At least it's reducing legal risk. It seems more understa

The article from this subthread contradicts this, though. Regarding recoverability of the situation, it says this: > By now the airspeed indications had returned to normal, but the pilots had already set in motion a sequence of events wh

What's the practical impact of choosing eMAG as the baseline CPU? Does it alter the weighing of the components in the final score?

The Arace purchase link for the Jupiter 2 kit says it's “in stock“, but it's actually for a discount coupon. The actual system can only pre-ordered. The Sipeed web site does not say anything about shipping timelines, and the produ

I'll bring it up with some folks. It probably won't change much because the z13 transition has finished by now. It's still good to know because RISC-V is in the same boat regarding Highway support today: we need scalar fallba

People reported challenges building V8 (whether upstream or the Node.js variant) on s390x with z13 support. I don't know if it was discussed on the porters mailing list because it's not public: https://groups.google.com

Does it have fallback paths for everything, though? Scalar if necessary? Projects that depend on Highway drop support for CPUs not listed in the Highway documentation, saying that they can't support these CPUs because they are incompa

As kbolino said, value objects are immutable. If you can get a reference to a value object in an array, the array has to be immutable. If you cannot get a reference, it's possible to maintain mutability, but all access would involve co

If you just want to get a bug fixed that annoys you, it's of course out of scope. If researchers want to showcase their ability (either individually or as an organization) to identify and address security vulnerabilities in complex mul

The libsanitizer library is imported from the LLVM sources into the GCC source tree. There are probably more examples of code sharing. Both projects are quite large.

You probably would prefer to use SUB with fault-checking to clear registers in general-purpose code, and only use XOR in early startup (and perhaps fault handlers), where error checking has to be suppressed. So both observations seem to al

Many of the conversions so far have been clearly faster. I don't think anything has been merged which shows a clear performance regression, at least not on CPUs with FMA support.

I find this puzzling. It does not seem to allow to stack PRs on top of other people's PRs? There is already an option to enable review comments on individual commits (see the API endpoint here: https://docs.github.com/e

While I don't disagree about (2), my experience suggests that LLMs are biased towards generating code for future maintenance by LLMs. Unless instructed otherwise, they avoid abstractions that reduce repetitive patterns and would help f

I think CC originally did have producing physical items in mind. For example, one use case for the NC licenses for photos was that you can pay someone to make a print and frame it for you. This went sideways when Flickr offered to streamlin

Employers might argue that such internal use and distribution would fall under the “exclusively under your behalf” clause in the GPLv3, which is inherited by the AGPLv3.

This procedure only applies to copyright-infringing content, not to trafficking in circumvention devices. It seems that in this case, it's the latter.

But that's a different process, not the usual notice-and-takedown notice procedure. If it's consider a circumvention device, there is no way to file a counterclaim, among other things.
