rwaksmunski··on Anthropic's growth just flattened
As an investor, what's the moat here? Being 6 months ahead of China's open source/weight models?
rwaksmunski··on Zero-Click Spyware Delivered via Targeted Ads: AdFection
And wBlock on Safari.
rwaksmunski··on Apple: Switch to Safari (From Chrome)
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.
rwaksmunski··on We never use AI. For anything
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.
rwaksmunski··on Stripe, Advent offer to buy PayPal for more than $53B
It's a bank in Europe
rwaksmunski··on OpenBSD has a use-after-free allowing local privilege escalation to root
The Rust ownership model prevents use after free. This type of a bug would not compile.
rwaksmunski··on VS Code inserting 'Co-Authored-by Copilot' into commits regardless of usage
Just when you think they've reached the bottom, they just keep digging.
rwaksmunski··on iPhone 17 Pro Demonstrated Running a 400B LLM
Apple might just win the AI race without even running in it. It's all about the distribution.
rwaksmunski··on Meta’s renewed commitment to jemalloc
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.
rwaksmunski··on Ask HN: Why is my Claude experience so bad? What am I doing wrong?
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
rwaksmunski··on SIMD programming in pure Rust
I use the slice::windows for that.
rwaksmunski··on SIMD programming in pure Rust
Every Rust SIMD article should mention the .chunks_exact() auto vectorization trick by law.
rwaksmunski··on AI Can Write Your Code. It Can't Do Your Job
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.
rwaksmunski··on P2B Modification Guide
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.
rwaksmunski··on AI Can Write Your Code. It Can't Do Your Job
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.
rwaksmunski··on Comparing AWS Lambda ARM64 vs. x86_64 Performance Across Runtimes in Late 2025
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.
rwaksmunski··on A Love Letter to FreeBSD
I got over 20 years of sane, reliable and consistent computing from the FreeBSD Project, thank you.
rwaksmunski··on Cloudflare Global Network experiencing issues
FreeBSD on bare metal hooked up to a nice network.
rwaksmunski··on Unofficial "Tier 4" Rust Target for older Windows versions
Tier 3 is max official
rwaksmunski··on Using FreeBSD to make self-hosting fun again
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?
rwaksmunski··on The MacBook Air 2025 Is Now Cheaper Than a Random Mid-Range Windows Laptop
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.
rwaksmunski··on MD RAID or DRBD can be broken from userspace when using O_DIRECT
This, fsync() data corruption, BitterFS issues, lack of Audit on io_uring, triplicated EXT2,3,4 code bases. For the past 20 years, every time I consider moving mission critical data from FreeBSD/ZFS something like this pops up.
rwaksmunski··on Andrej Karpathy – It will take a decade to work through the issues with agents
AGI is still a decade away, and always will be.
rwaksmunski··on Qualcomm to acquire Arduino
At least it's not Broadcom
rwaksmunski··on Deloitte to refund the Australian government after using AI in $440k report
Well, when you have a bad idea you want to implement but don't want to take responsibility for it, you keep on hiring consultants until you hear what you want to hear. Quality of the consulting is irrelevant and interns or AI will do just fine. When the project inevitably implodes, you blame the consultant. Your own employees will give you advice on what's best for the company, not necessary what's best for you so you stand on their neck until they quiet down and learn their place. By the time anyone figures out what happened you already moved on with outstanding resume bullet point.
rwaksmunski··on The Toyota Corolla of programming
If PHP is a Corolla, whats a Land Cruiser then? Rust?
rwaksmunski··on Bzip2 crate switches from C to 100% Rust
Common Crawl delivers the data as bz2. Indeed I store intermediate data in zstd with ZFS.
rwaksmunski··on Bzip2 crate switches from C to 100% Rust
I use this crate to process 100s of TB of Common Crawl data, I appreciate the speedups.
rwaksmunski··on FCC Chair Brendan Carr is letting ISPs merge–as long as they end DEI programs
[flagged]
