An RTL performance erratum in the Apple M3 Neural Engine throttles DRAM weight streaming throughput down to 17–19 GB/s from the nominal 45–60 GB/s, whenever the total weight size is an integer multiple of 1 MiB, which currently affects 7 of ANEMLL ’s 15 models. Avoiding the problematic path in the kernel DMA engine's…
If you read my recent post about Postgres you may have noted that Postgres operates primarily with fixed-size blocks of memory called “pages.” By default, Postgres pages are 8KB. This number is tuned to match operating system page sizes which are tuned to match hardware cache sizes. If you were to run Postgres on…

This week, we continue our four(and a half)-part (I, II, III, IVa, IVb, addendum) look at pre-modern iron and steel production. Last week, we looked at how a blacksmith reshapes our iron from a spo…
The internet is big. Really big . You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think the /22 you got as a LIR was big, but that’s just peanuts to the internet.
For a recent project I've been working on, I wanted to include a graph showing the relationships between different artists on Spotify. Spotify provides the data directly from their API, and I had everything set up to pull it for a user's top artists and into the browser.
Celebrating a little bit of legacy from Placemark and a new product for hydraulic simulation
Cache-Oblivious Algorithms Cache-oblivious algorithms seemed incredible to me when I first heard about it in 6.854 (Advanced Algorithms). It’s relatively straightforward to imagine algorithms that utilizes information about page size $B$ and cache size $M$ to create efficient data structures. However, cache-oblivious…
The other day Steve wanted git alchemy done on the Rust repo. Specifically, he wanted the reference and nomicon moved out into their own repositories …
It's no secret that authenticating into services is an unresolved topic. With time, we have managed
Instead of asking “Is university good?”, ask “Do I have something more compelling to do?”. Instead of “Should I do a PhD?”, ask “Where can I find the best environment to grow as a researcher?”.
Some of the world’s largest Internet firms have taken steps to crack down on disinformation spread by QAnon conspiracy theorists and the hate-filled anonymous message board 8chan . But according to a California-based security researcher, those seeking to de-platform these communities may have overlooked a simple legal…
I was looking through my iPhone device analytics as I plan my iOS 13 updates and noticed something that really jumped out at me.
You had things running with occasional glitches and there was always an excuse “It works in my machine” as there is rarely identical…
Why poker may be more instructive as a game than chess
Having a home server and a few smart plugs leads to interesting data points like this one. Well, interesting to me, at least.
I find myself telling people that they will have to pry org-mode from my cold dead hands. Which befuddles me. Why, as an ingrate software nerd who has soured on software technology — talk about biting the hand that feeds — do I evince such strong sentiment about a software program?!
After I wrote Why Zig Over Rust for Systems Programming, the obvious next question was C. The Rust question was about safety and how much ceremony I was willing to accept for it. The C question is different, because Zig and C want the same things. Both are small languages without a Garbage Collector and both stay…
I expect I'll annoy everyone with this post: the anti-JavaScript crusaders, justly aghast at how much...
There are many ways to evaluate a developer. Should we use quantitative metrics or stick to qualitative ones?
It turns out that a _very_ long HDMI cable, a Steam Controller 2 and Bazzite on a second drive was all I needed to get a comfortable couch gaming experience.
Every now and again, someone emails me and asks for very general advice. ("How do I change the world?") With the caveat that I've only lived a fraction of one life, and am still trying to figure things out, here's the advice I'd give past me.
Successful people who use to-do lists and the boring takeaway.
TL;DR: Down and to the right I wasn’t going to do this post until I learned IBM PR is out browbeating reporters (one of the rare activities where the company is still world class) for being “too ha…
