RISC-V Testing Lapse Resulted In Wrong MIPS RISC-V Vendor ID Landing In Linux 6.18
An interesting anecdote from this week’s batch of RISC-V fixes for the Linux 6.18 kernel exposed that the MIPS RISC-V/JEDEC vendor ID was wrong for code merged at the start of the kernel cycle. The testing hadn’t caught it either as the QEMU emulation also ended up inadvertently using the wrong vendor ID too… ⌘ Read more

@movq@www.uninformativ.de That’s what tests are for. To fix them. :-D

All my newly added test cases failed, that movq thankfully provided in https://git.mills.io/yarnsocial/twtxt.dev/pulls/28#issuecomment-20801 for the draft of the twt hash v2 extension. The first error was easy to see in the diff. The hashes were way too long. You’ve already guessed it, I had cut the hash from the twelfth character towards the end instead of taking the first twelve characters: hash[12:] instead of hash[:12].

After fixing this rookie mistake, the tests still all failed. Hmmm. Did I still cut the wrong twelve characters? :-? I even checked the Go reference implementation in the document itself. But it read basically the same as mine. Strange, what the heck is going on here?

Turns out that my vim replacements to transform the Python code into Go code butchered all the URLs. ;-) The order of operations matters. I first replaced the equals with colons for the subtest struct fields and then wanted to transform the RFC 3339 timestamp strings to time.Date(…) calls. So, I replaced the colons in the time with commas and spaces. Hence, my URLs then also all read https, //example.com/twtxt.txt.

But that was it. All test green. \o/

Clang 21 Delivering Nice Performance Gains On AMD EPYC Zen 4 With HBM3
One of the areas I’ve been meaning to run more benchmarks on this season has been for the recently released Clang 21 compiler. Back in September when LLVM Clang 21 was debuting I ran some initial benchmarks and found it to deliver some nice performance gains on AMD EPYC Zen 5 but then have been busy with other benchmarks/articles for expanding that testing. Recently with having some spare cycles and gratis access still to the Microsoft A … ⌘ Read more

Linux 6.19 Slated To Land “mm/cid” Rewrite That Has Very Positive Performance Potential
A set of Linux kernel patches posted back in October for rewriting the kernel’s memory-mapped concurrency ID code for some nice performance wins looks like it will land for Linux 6.19. This is the code that prominent Intel engineer Thomas Gleixner found to yield up to an 18% improvement for the PostgreSQL database. My testing of this “mm/cid” code has also shown some nice performance wins too… ⌘ Read more

AMD ROCm 7.1 vs. RADV Vulkan For Llama.cpp With The Radeon AI PRO R9700
In the past we have seen Llama.cpp with Vulkan outperforming AMD’s ROCm compute stack in some of the large language model (LLM) AI benchmarks. Curious if anything has changed given the recent ROCm 7.1 release, I ran some benchmarks of an up-to-date Llama.cpp using the AMD ROCm back-end compared to the Vulkan back-end with the latest RADV driver. For this round of testing the Radeon AI PRO R9700 graphics card was used. ⌘ Read more

@prologic@twtxt.net no, I really meant small. I only have a handful of GiBs left of storage. If you can wait until mid-December, then no probleml. Right now it is kind of running on fumes. For testing, and to do not disturb anyone timelines, I recommend you run a small test instance. Running GtS is easier than running Yarn, by the way. Word.

@prologic@twtxt.net ah, yes, one of those, yes. Too small for testing though. 😅

First real test failed trying to lookup / follow @david@weaknotes.com

For those curious, the new Twtxt <-> ActivityPub bridge I’m building (bidirectional) simply requires three things:

1. You register your Twtxt feed to the bridge: https://bridge.twtxt.net
   
2. You verify that you in fact own/control the feed by putting the verification code somewhere on/in your feed (doesn’t matter where or how)
   
3. You proxy/forward requests for /.well-known/webfinger to the Bridge bridge.twtxt.net.
   

I’m still testing through and ironing out bugs 🐛 Please be patient! 🙏
