I can admit by now: doing this blockchain stuff was not my thing. I tried it for four months and learned my lesson.

Just wanted to put this out loud for the sake of therapy... Now I know a bit of that and in long run that gives me a better perspective of the tech industry.

A non-rustianated opinion about DMA patches: it should be part of patch set that requires DMA.

I.e. I was eager to try it out but there is no payload to test. I did add lei filter to get everything from rust-for-linux matching DMA so looking forward to do this in future :-)

An Open Letter to All European Politicians and Leaders to Abandon X/Twitter:

"By abandoning X/Twitter, leaders can reduce its credibility, promote fairer alternatives, and take a stand against the spread of disinformation, ensuring democratic principles are upheld."

H/T to @everton137 for organizing this - already close to 1,000 signatures:

We meet again after three week break:

https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git/log/?h=v4l2-loopback

I collect below the top-most commits that are locked in as pretty much dead obvious changes and the top-most commit (whatever its name happens to be) is the dumpster.

I started this by unpurging the top-most just to recall where I was at. Commit ID's live as I might add a new commit in any position (as deep down in history as possible as it makes sense).

so i heard you wanted a filesystem that is copy on write, in-tree (so not zfs), does not eat your data (so not btrfs) and is not maintained by a certain person (so not bcachefs)?

i present you, ocfs2, or oracle's cluster file system version 2

you say that it's for shared network disks in clusters? here i put it as a root filesystem, on a core 2 duo thinkpad, running off a single usb stick on usb 2.0

If I want to test Ubuntu kernel in a VM what do I need to change in this old snippet of mine:

git fetch --no-tags git://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack refs/tags/cod/mainline/v6.3-rc7:refs/tags/cod/mainline/v6.3-rc7
git checkout next
git checkout -b next-test
git merge cod/mainline/v6.3-rc7
LANG=C fakeroot debian/rules clean
LANG=C fakeroot debian/rules binary-headers binary-generic

The problem: that URL no longer responds.

Venäjän sensuuriviraston johtaja on tyytyväinen siitä, miten Twitter / X on viime aikoina muuttunut

Viraston johtajan mukaan Venäjä saattaa pian taas sallia Twitterin käytön - palvelu on ollut estettynä maassa jo useamman vuoden ajan.

GNU Gold Linker Is Deprecated & Will Be Gone For Good Without New Developers

With the recent GNU Binutils 2.44 release, one of the changes is worth calling out in its own article: the GNU Gold linker is now officially deprecated and is now being segregated to its own extra Binutils package but risks being removed all together without new developer volunteers stepping up to maintain this linker...

I've said this before but if you need to test something with graphics but don't want to use GPU, try either:

1. https://github.com/emoon/rust_minifb
2. https://github.com/emoon/minifb

They give you display and 32-bit framebuffer. No bullshit. Neither is dependent on the other. They just implement same things.

Even Web is supported (in both) when compiled to wasm (I'd guess).

Sometimes using GPU can really get in the way of testing so good keep in mind :-)

Since I've said negative things about Microsoft and Windows in the past, I also have to give credit where it is due (because otherwise I would not have any integrity).

Thanks MS for taking the righteous path, my respect for the company raised by factors:

We can have our differences in tech matters but then there are things that actually matter like human rights for instance.

Packer is superb for e.g. testing kernel:

https://www.packer.io/

I like to use it together with NixOS so I end up with two files describing the operating system.
