The new 'function view' in @marimo_io. Seeing this, I wonder if marimo should add smarts such that `marimo edit` is edit mode and `marimo run` renders the same py file as a docs site. Code cells interspersed with doc cells. If 'function view' can happen automatically (without…

Yet again, a little myopic take on "systems". There's prior art in the form of mainframe tech, and that certainly doesn't fit the "for decades, everything was lame" framing . Mainframes were (and are) way ahead. There are specialized processors (SAPs) for handling I/O, and there…
io_uring completely rewrote the assumptions of I/O as a syscall. It's an incredible development that's catching on quickly in distributed systems everywhere. Read this article on Systems Saturday! 🔗 Link in reply!
celebrating 25 years of Quake 3 CPMA: the most skillful, hardest, fastest, greatest FPS of all time. the world's best esport. the true start of the aim community and freeform movement. the first frag movies and the birth of montages. watch it all at once. holy shit! by entik
I think I can see the parallel to mainframe architecture, but with commodity OS & hardware. Mainframe is like pic 2 because PR/SM is a type 1 hypervisor, with z/OS being the "kernel". It's like pic 3 because PR/SM is not a thing that admins/users need to think about, as it's…

If every disagreement feels like friction instead of fuel, your team is stuck.
Look forward to discoveries from @VictoriaMetrics and other projects that care about perf.. using this.
Profiling: you are doing it all WRONG! The SHOCKING truth about CPU vs. real time Now that I get your attention :) My perf latency profiling changes merged: web.git.kernel.org/pub/scm/linux/… First profiler ever that samples realtime (not CPU time) and suitable for latency optimization
Do statins cause dementia? In this trial, elderly patients with dementia saw condition go away when taken off statins and then return when statins reintroduced. via @LDLSkeptic

Harcombe/Kendrick vs Associated Newspapers... I'm delighted to say it's finally over! 5.5 years after the articles were published, they are down and an apology has been made. Thank you SO much to everyone who made this even possible - especially Claire & Dominic at Carter-Ruck…

Sunday rant. For software engineering, my sense is that the phrase “premature optimization is the root of all evil” has massively backfired. Its from a book on data structures and mainly tried to dissuade people from prematurely write things in assembler. But the point was to…
Following the crowd and pre-established rules is often a losing strategy. Break the rules when you can, invent new ones if needed… that’s how you leave your mark and spur progress. You don’t need to cheat and lose social capital: announce what you are doing. Get allies. Just…
It’s incredible how much optimisation is possible in programming. Unless a programming language makes the most performant way the only way of doing something, this level of gainz will be limited to a few minds. developer.nvidia.com/blog/accelerat…
Wonder why IBM’s Aspera FASP tech isn’t baked into firmware on OSA Express cards, switches/routers/IPEXes, RoCE, and so on… Surely at least one of these things provides significant benefits.
Wow, NVIDIA BlueField-2 DPU is like IBM Z’s OSAExpress, FICONExpress, CryptoExpress combined!
