We haven’t found evidence of Stingrays being used at protests in the US yet, but if you’re going to a No Kings protest this weekend, why not bring Rayhunter to be sure? Don’t forget to charge and update it, then let us know what you find! https://efforg.github.io/rayhunter/support-feedback-community.html

New C compiler dropped:
https://git.sr.ht/~jprotopopov/kefir

Looks interesting. GPLv3 for the compiler itself. Some optimizations; have not looked into them yet. only x86_64 backend so far.

X is where you find the people who think they run the Internet.

Bluesky is where you find the people who think they ought to run the Internet.

Mastodon is where you find the people who actually do run the Internet, and kind of wish they didn't.

Well, I just got laid off from my job. If anyone needs a talented embedded systems engineer or hardware engineer with strong experience in video hardware, send me a message with details of a job opening and I can provide a CV. Remote work preferred, but I can work anywhere in central Minnesota. Boosts welcome and encouraged.

My first die shots. You can see a lot more than I'd imagined without a microscope. This is a 1:1 macro lens, and just changing the angle/size of the light source gives you a ton of control.

Weekly GCC update:

Optimization improvements:
* Copy prop for aggregates improvements; now into args
* Recongize integer zero as zeroing for memset into aggregate copy or memcpy
* Improve VN support over aggregates copies
* Recongize saturation multiple more
* Allow for more mergeable constants to be placed in the mergeable section

C++ improvements/changes:
* Implement C++20 (Defect report) P1766R1: Mitigating minor modules maladies
* Fix parsing of non-comma variadic methods with default args
* Warn on #undef/#define cpp.predefined macros
* Implement C++26 P1306R5 - Expansion statements
* Implement P2036R3 - Change scope of lambda trailing-return-type
* Finish up P2115R0 implementation (unnamed unscoped enums)

Target changes:
* epiphany and rl78 are marked as obsolete targets
* LoongArch: 128bit atomics support
* LoongArch: _BitInt support
* x86: Add target("80387") function attribute
* RISCV: Add MIPS prefetch extensions
* aarch64: Fix CMPBR extension

The more I hear about RISC-V the more it it sounds like XMPP but in even worse because you can't just patch your client. Vendors implement, it doesn't match the spec, "proprietary performance extensions" and you can recompile for every different CPU because of that

Summary of last week's changes in GCC:
* Many GCCrust changes were merged in (200+)
* Improvements to diagnostics infastructure
** supporting nesting levels
* _BitInt support for s390
** changes needed to support for loongarch too
* Update versions of MPC, MPFR and GMP in contrib/download_prerequisites
* Improvments to the VN for reading past an aggregate copy
* copy prop of aggregates improvements
* Improve handling of musttail calls in C++ with -fsanitize=address and -O0
* Fix/Improve constants that are mergeable; supports non power of 2 in some cases
* Implement C++26 P1061R10 - Structured Bindings can introduce a Pack

Meet our awesome mascot in the colors of the 2025 edition!
Bringing that unmistakable French touch to the conference.:)

Feel free to download and use them – and keep an eye out, you might just spot them on some slides this September!

Remember when RFK Jr said he wanted to make lists of autistic people?

Disabled advocates warned that was just the beginning. That the violation of medical privacy would be used for nefarious purposes.

Today the regime announced it’s giving all personally identifiable information of Medicaid enrolees to ICE.

That’s right, ICE bullies will now have access to almost 80 million people’s personal info. This is an atrocious violation of privacy that will no doubt be used to target other groups as well.

It won’t stop with immigrants. It won’t stop with autistic people.

Fascists never stop and we must all fight back.

You know, I remember times where I would concede proprietary software was *better* than #floss (due to features, support or however you want to define it).

Thanks to all the AI crap, micro-optimizations, tracking and privacy/security violations and useless changes I actually think most #floss apps are much better than their proprietary alternatives now. I don't have to keep clicking "maybe later" over and over. That's worth a lot to me OK?

That talk is incredible. If you're into hardware in general, you should watch it.

🖥 This is big: Android's Linux Terminal is available on the Galaxy Z Flip 7!

You can run full Linux apps in a VM. And with DeX, on an external display!

It's the first non-Pixel device to support it. Curiously, the Z Fold 7 doesn't have it. With the Linux Terminal + Samsung DeX...the Z Flip 7 might even be a better portable PC than the Z Fold 7? At least when it's docked!
