And wBlock on Safari.

For those needing uBlock Origin please give wBlock a try. It's also open source but uses native Safari content blocking APIs. It's faster and works and syncs with iPhones through iCloud.

I use it for new code base summary, documentation lookup, code review, improvement suggestions, security audit, everything but writing code, I still do that by hand. I'm more productive and my skills improve. Reviewing slop burns me out. I can't be the only one.

The Rust ownership model prevents use after free. This type of a bug would not compile.

Just when you think they've reached the bottom, they just keep digging.

Apple might just win the AI race without even running in it. It's all about the distribution.

New comment by rwaksmunski in "Meta’s renewed commitment to jemalloc"

rwaksmunski — Tue, 17 Mar 2026 06:41:18 +0000

jemalloc 5.2.1 vs mimalloc v3.2.8 in Rust software processing hundreds of Terabytes. Could not measure a meaningful difference, but mimalloc would release freed memory to the OS a lot sooner and therefore look nicer in top. That said, older mimalloc from default rust crate would cause memory corruption with large allocations >2Gb in about 5% of the cases. Stuck with battle hardened jemalloc for now.

AI seems to work a lot better once you acquire some AI equity, you go from not working at all to AI writing all the code. /s

I use the slice::windows for that.

Every Rust SIMD article should mention the .chunks_exact() auto vectorization trick by law.

New comment by rwaksmunski in "AI Can Write Your Code. It Can't Do Your Job"

rwaksmunski — Thu, 25 Dec 2025 06:55:32 +0000

I'm saying it's not good enough to write code yet, but good at explaining code. If it can't that means I messed up and I need to make it clearer. Once it's explanation and my meaning line up, the code is good enough and I move on. Meta point is that people are using AI for the wrong thing. It's great at consuming, not creating.

New comment by rwaksmunski in "P2B Modification Guide"

rwaksmunski — Wed, 24 Dec 2025 20:33:40 +0000

Early in 1999 my 1st build was a Celeron 300A on Asus P2B-LS overclocked to 450. Later upgraded to 1.4Ghz and 512MB ECC RAM. Much later running FreeBSD as a home server probably till 2015 when the power supply finally gave out, I wish I kept it. Got me through the capacitor plague and was competitive with Pentium 4 for a while. Absurdly stable and quite snappy with a 10k SCSI system drive. Would love to install Windows 98SE again on it and play some Unreal Tournament.

It's decent at explaining my code back to me, so I can make sure my intent is visible within code/comments/tracing messages. Not too bad at writing test cases either. I still write my code.

Been doing Rust lambdas for 4 years now, Rust is absurdly fast, especially when compared to non compiled languages. If anything, Rust is even faster than those benchmarks in real world workloads.

I got over 20 years of sane, reliable and consistent computing from the FreeBSD Project, thank you.

I prefer developing Rust on FreeBSD, memory allocator, scheduler, network stack, kqueue, dtrace and other instrumentation are all superior than the Linux counterparts. What's missing for you?

My Retina MacBook Pro lasted over a decade, that's 200$ a year plus $50 battery replacement and $8 speaker. It still runs fine. Macs are an absurd value/quality for money. If M series Macs run this well, no one else comes even close.
