Selfhosted@lemmy.world•Moving a Proxmoc 256 MB NVMe install to larger NVMeEnglish
2·7 天前This would be a great application of btrfs. Copy over the boot-partition directly via
cp /dev/nvme{0,1}n1p1or similar.
Then, simply add the data partition(s) to btrfs. You can then tell btrfs to migrate all data out of the old partition, and finally remove it. All in a running system.I have migrated the rootfs on running systems before using this method, it’s a super clean approach.
BTRFS also nicely handles the redundancy with its checksums. Usually you can’t fix bitrot between two drives, but btrfs can tell which version is correct. Makes scrubbing easier.

Privacy@lemmy.ml•Signal to Ottawa: We'll Leave Canada Before We Help You Spy on Users
3·7 天前Installing an apk, installing directly, …
As opposed to installing from Fdroid, from gplay, …You can also go by source, like with the stores. For example Signal android can be installed from their website (by downloading an apk).

1·8 天前Modern version would be a silicon device not using any metal, that has a very low power mechanism (perhaps mechanical/chemical) that wakes it up much later where it then works as a bug. For example.

Selfhosted@lemmy.world•Banned from Discord for a frog emoji (thanks "child safety"), so I bankrupted myself building FrogTalk – a self-hostable Discord/Telegram killer 🐸English
9·9 天前I checked the actual code and there is no e2ee, at all.
It has some of the basic setup stuff, like giving you a recovery file, and messages are seemingly encrypted, but everyone can decrypt everything and the platform has none of the structure to deal with all the issues proper e2e brings.As a very simple test: If you write a message in a server, close the tab. Make a new account and open that chat. You can read the message. Meaning anyone can.
The way actual e2ee does this is it signs messages for anyone in the chat at that moment. Anyone new can’t read old messages unless an old member sends them the contents.Also this stuff is buggy in the actual functioning.
Also it’s full of trackers and weirdly loads youtube for no reason.
Also it’s full of nazis, the actual state is so much worse than the screenshots shown in the post. The top channels are “4chan” and “wagnersdom”.

Linux@programming.dev•Linux 7.0.6 Released To Finish Mitigating the Dirty Frag Vulnerability
2·12 天前This one is so generic it let’s you get around any of that very easily.
You don’t even need to interact with the filesystem, you can just change a cron script or system library and let some other process execute it. Or you can change /etc/passwd to give yourself access to a root user, which iirc is what this dirtyfrag vulnerability proof of concept did.You can pretty much write to any file on the filesystem with one syscall (that is not a write syscall) and in a way that does not count as writing in any of the normal ways, so won’t even trigger file change events etc.

Linux@programming.dev•Linux 7.0.6 Released To Finish Mitigating the Dirty Frag Vulnerability
6·12 天前Sadly not, as far as I have seen all the various pagefault vulnerabilities of this wave are in obscure modules.
Desktop kernels tend to have everything installed so even unusual software will run. Android has a lot fewer modules and builtins, and also regulates what interactions can be done, usually passing such things through system components first.
None of them so far were built into android kernels. Also most of them were not in my own custom kernel either.

Linux@programming.dev•Linux 7.0.6 Released To Finish Mitigating the Dirty Frag Vulnerability
18·12 天前LTS is also patched.
In addition to Linux 7.0.6 stable, the Linux 6.18.29 LTS kernel was also released today with the sole change being this same patch from Hyunwoo Kim for resolving Dirty Frag.

Technology@lemmy.world•Kevin O’Leary’s proposed 9GW "hyperscale" AI data center in Utah will consume double the state's entire electricity usage and generate the waste heat of 23 atom bombs a day.English
5·14 天前No, 9GW of electricity, and they claim 16GW total. With a greater than 50% efficient gas plant.
Most changes are updating the copyright year.
After that, it’s pretty much (or maybe completely, I haven’t checked exhaustively) for the --help and --version flags, not for the core part of exiting with a certain exit code.

Selfhosted@lemmy.world•Serious Linux vulnerability affecting nearly every system. Patch your systems.English
3·24 天前I haven’t checked too deeply but I think fedora dropped the affected system between kernels 6.6 and 6.12 somewhere. 6.12+ appear to not have the modules.
Not too surprising given the system has been deprecated for a long time.

World News@lemmy.world•Europe—not US—first to authorize Moderna's combo mRNA flu-COVID vaccineEnglish
2·27 天前Flu and corona are both “common cold type” viruses defeating resistance in some way. For coronaviruses that method is stopping the body from building effective resistance by all means possible, so that is why vaccines tend to not work too well.
For the flu it’s the many variations and its tendency to change further and need new antibodies.
So I don’t think a specific flu strain is hard to make a very effective vaccine for, but ofc this doesn’t yet solve the flu problem.
The immense speed at which mRNA vaccines can be developed might improve that in the future, where this here could be one of many steps to get regulatory approval for blanket mrna and actually be permitted to change them at that pace.In principle mRNA should let you crank you vaccines for new diseases/flu-strains in under a week. If this can fully stop the flu?.. I doubt it. Whatever does solve it will probably make use of this tech though.

Technology@beehaw.org•Microsoft encourages chunk of experienced US staff to leave
5·29 天前Headline sounds like they want them to relocate to Europe. Bummer.
Try to log the stdout of your services, I dare you.
openrc is just missing some pretty essential things. I’m not saying to copy journalctl, but at least dump stdout into some tmpfs file by default.
To have some sane basic logging on hand if a service breaks weirdly or is misbehavingy you’d need to edit that specific service file and restart. And most of the time look up the spec of the specific service command to remove log supression.
Unlogability alone makes openrc quite a nightmare for a lot of setups. I’ve wasted hours repeadedly that would have been 5min had I gotten the log upfront.

Linux@programming.dev•Valve Developer Improves The Linux Gaming Experience For Limited vRAM Hardware
5·1 个月前GTT (gpu swap) is handled by the gpu driver, so only nvidia can see if they can add it to their closed source drivers. radv is the amd vulkan driver.


What a coincidence, I just checked and mine is 1970-01-01 01:00:00.000000
Edit: friend of mine got 1969-12-31 18:00:00.000000, we should open a club.
