Thank you! It seems to be what I'm looking for.

I just tried building and running it. Surprisingly many websites already load fine, though Youtube doesn't and Vimeo/Reddit comment section crashed it. Still, the results are quite encouraging! It takes ~6GB of HDD to build it.

I've recently been wondering: could you re-compress gzip to a better compression format, while keeping all instructions that would let you recover a byte-exact copy of the original file? I often work with huge gzip files and they're a pain to work with, because decompression is slow even with zlib-ng.

Thanks! Any ideas why it didn't get merged? Clearly 7-Zip has some development activity going on and so does this fork...

I worry that 7-Zip is going to lose relevance because lack of zstd support. zlib's performance is intolerable for large files and zlib-ng's SIMD implementation only helps here a bit. Which is a shame, because 7-Zip is a pretty amazing container format, especially with its encryption and file splitting capabilities.

I don't want this to sound cynical, but do we have any examples where the US government successfully got the corporations to actually increase security, as opposed to just gaming the regulations to make more money instead?

I'm surprised by the performance. Doesn't qemu have dynamic recompilation capabilities?

New comment by d33 in "Visualizing Ext4"

d33 — Mon, 08 Jan 2024 11:39:52 +0000

This inspired me to do this experiment:

dd if=/dev/zero bs=1K count=$(( 256 * 3 )) of=a.ext4

mfks.ext4 a.ext4

mkdir a

sudo mount a.ext4 a

cd a

sudo chown 1000:1000 .

python3 -c 'open("a", "wb").write(b"\xff\x00\x00" * 2000)'

python3 -c 'open("b", "wb").write(b"\xff\xff\x00" * 2000)'

python3 -c 'open("c", "wb").write(b"\xff\x00\xff" * 2000)'

cd ..

sudo umount a

(echo -n 'P6\n512 512\n255\n' ; cat a.ext4 ) > a.ppm

convert a.ppm a.png

The resulting a.png is reversible - you can convert it back to .ppm file, skip first 15 bytes and you should get a valid .ext4 back.

Previously mentioned Depthboot from Eupnea Project (https://news.ycombinator.com/item?id=36888598), while allows you to install Linux distributions on Chromebooks, requires user to generate modified images with custom kernels, which is harder to maintain than mainline/original distribution kernels. Meanwhile Chrultrabook project is actively contributing to upstream projects, allowing for installation of Linux distributions from original images thanks to proper UEFI support with Coreboot - this makes it more future proof, despite more steps required for Coreboot installation.

d33 — Thu, 27 Jul 2023 11:00:15 +0000

Timely! I just deployed it on our company server. There's a hidden gem that's not enabled by default and really helps when pair programming in Jupyter:

https://jupyterlab.readthedocs.io/en/stable/user/rtc.html

Here's a Dockerfile that enables it:

    FROM jupyter/scipy-notebook:2023-07-25
    RUN pip install jupyter-collaboration
    ENV DOCKER_STACKS_JUPYTER_CMD="lab --collaborative"

Usage:

    docker build . -t jupyter-collaboration && docker run -p 10000:8888 jupyter-collaboration

The only missing would be having more than one cursor and some convenient way to start and attach remote servers, e.g. over AWS...

Is "zstd" a typo? Couldn't find any sources on it (unless we mean the compression standard), including Wikipedia.

d33 — Mon, 12 Jun 2023 12:37:56 +0000

For that to work you have to trust the firmware. Overwriting with something random, saving what was fed and then cross-referencing that against the storage could work better, but there's still some non-zero chance that something you're looking for is in a buffer, unreachable part of the disk or the like.

Encrypting the hard drive and then removing the key has a better chance of rendering the data unusable.

Do we have a proof that this means that they're ready for the late game, as opposed to just investors being desperate?
