Security issues back in the day: by executing a specially prepared code you can place private data of some process in CPU's cache, and then predict its contents using a timing attack 💪.
Security issues today: I opened a big file and ran out of memory 😭.

As a first-year undergrad, I took intro to film. We had to write about a movie of our choice. For whatever reason, I chose "Mr. Mom." My memory of it, which I'd seen as a kid when it came out, was of playful subversion of gender conventions. Holy shit was I wrong. So I wrote a paper about sexism, with some xenophobia I'd totally missed the first time thrown in too. It probably wasn't a good paper, but writing it really helped flush my system of a certain kind of pernici…

After spending the last few weeks watching the #Artemis live stream, I brought the family to Huntsville, AL and the U.S. Space and Rocket Center. I went to Space Camp and Space Academy when I was a kid, so this whole place is a core memory for me. Time to geek out!

A person with a beard and sunglasses takes a selfie outdoors in front of a signpost on a sunny day. They are wearing a blue shirt with a partially visible yellow logo. Behind them to the right, two vertical blue banners hang from a pole. The left banner displays the NASA logo and the text "Smithsonian Affiliate". The banner next to it displays the text "U.S. Space & Rocket Center", "Home of Space Camp", and the orange "ASTC" logo. In the background, a large metal archway shows the letters "RANC…

A black‑and‑white image of a large metal public sculpture in a city plaza. The central structure is a tall, funnel‑shaped form made of intersecting metal rods, surrounded by curved wave‑like metal elements. Buildings with Chinese signage and trees frame the scene. The ground features circular patterns.

A black‑and‑white photo of a brick walkway covered with dry leaves. In the center lies a small rectangular photograph or paper, partially hidden by the leaves. The object shows a bright band at the top, as if from light exposure. The scene evokes themes of memory and time.

#Software peeps: do you still do box diagrams to work out how your structures will sit in memory?
#Lisp

A section of a design document I am working on, comprising text surrounding a box diagram. The text is:

In the beginning was the Word

My intention is that memory will be considered as an array of 64 bit words.

Each word may be considered as

1. a cons cell: two instances of object32, each having one mark bit, three tag bits and 28 payload bits;

2. a single object64, having one mark bit, seven tag bits, and 56 payload bits.

Note that, for any word, the first four bits comprise the mark and …

As part of the ongoing effort to reduce VRAM bloat in ngscopeclient I've added some nice debug tools (currently accessible by Window | Memory Analysis but that will probably get moved to the debug menu at some point) to show you the full list of AcceleratorBuffer objects along with a bunch of metadata.
Haven't figured out how to right align the column titles but this is a debug visualization so not a huge priority.
Rows with more than 10% overhead (capacity > 1.1*size)…

Great talk by @… of #GNU #Hurd fame, in a packed room, selling the the Hurd really well (in my not entirely unbiased opinion, of course) and starting with
It'…

A slide on OS support (cont'd)

* Translator records in /dev and /servers
* Used to be a Hurd-specific ext2 extensions
* Now using xattrs by default
* Can now cross-install completely from Linux

* FS JBD2 journaling support (Milos Nikic)
* In progress

* Console xkb keyboard layout (Etienne Brateau)
A slide on Current state
* Rather stable
* Have not reinstalled boxes for a decade
  * Debian buildds keep building packages
* ~75% of Debian archive builds out of tree
* XFCE, gnome, KDE, ...
* Support merged upstream
* gcc, glibc, llvm, rust, ...
* Debian distribution
* Guix/Hurd released!
Slide on Dissemination

* News coverage
* Quarter of the Hurd (QotH) (Joshua Branson) 
* Guix/hurd (Manolis Ragkousis, Janneke Nieuwenhuizen, Yelninei) 
  * https://guix.gnu.org/blog/2024/hurd-on-thinkpad/
* Alpine (Sergey Bugaev) | z | |
 Slide: So, what do we have?

* x86_64 SMP
* SATA/USB disk/cd, all in userland
* netwokr driver & TCP/IP all in userland
* kernel only manages tasks, memory, IPC
* go, rust, ocaml, ghc, some java...
* Debian (~75% packages)
* Guix
* som Arch, some Alpine
* An the usual Hurd stuff: user-controlled translators, fine grain access control, sub-hurds.

Fuck. I was wondering what was going on with my computer since it was so slow, but I assumed it was topaz AI working in the background. Then I got this alert.
Had just updated the BRAW Toolbox plug-in, and when I ran activity monitor I watched that plug-in go from single digit gigabytes of memory to over 80. Meanwhile I was wondering what on earth was causing my MacBook Pro to literally /run down the battery/ while plugged into mains power...
Seems that plugin is dodgy...

My road bike has a BB30 (press-fit) bottom bracket. Yesterday I noticed it was creaking, so I pulled out my $50 BB30 removal tool, refreshed my memory on how to remove a bottom bracket with a bit of YouTube, pulled the thing apart, cleaned and greased everything, put it back together, and now it doesn’t creak. So satisfying. #BikeTooter

So, I have an answer to my previous question about GPU transfer efficiency.
Original code: write data to staging buffer on CPU, vkCopyBuffer to GPU local memory, run int-float32 conversion on GPU out of that buffer. The copy operation shows 50% SM occupancy by compute warps, 50% unallocated warp slots in active SMs.
GPU memory write bandwidth is sitting around 2%, about 1.9 ms copy/shader run time.
