About an hour ago, the sky turned blood red over Bavaria, Germany. It's the first time I've ever seen an #Aurora in my life. It was so bright to be easily visible with the naked eye. An absolutely jawdropping experience. 🖖😳✨
#polarlights #northernlights #solarstorm
cc @tagesschau @DLR @dlr_next @stim3on

at 22:29 they got a lot brighter, covering half if the sky; even some green visible at the bottom; another 10s exposure
vertical 10s exposure at 22:37
before fading again, they moved westward in front of the moon, here an 10s exposure at 22:46 showing distinct lines shaped by the magnetic field

@ProjectPhysX @tagesschau @DLR @dlr_next @stim3on yeah, it was amazing to see the lights with the bare eye down here in bavaria. I never would have imagined that it would be possible to get more than a faint green glow here. And yet, here we are... All the colors visible :)

Northern lights with green and red/violet colors. Trees at the bottom of the picture . There is a better distinction between red and violet

idk should i give in and raise the char limit? masto should shorten long toots now anyway, is this correct?

brot,
@brot@social.tchncs.de avatar

@milan 2x the current limit should be a nice middle ground. I mostly reply to posts and hate to double answer - so I kinda rewrite the reply to stay within the limits. If that is not possible, I seriously consider not replying.

Have you heard of anyone on your server that opposes a higher limit?

ich so: ach toll, ich kann ja jetzt in dem container da das ansible dings nutzen, was ich hier erfolgreich in nem linux container getestet habe

ansible so: "module_stdout": "/usr/bin/python3: can't open file '/var/tmp/ansible-tmp-1705848359.200771-14071-213516649617982/AnsiballZ_postgresql_user.py'

@milan @thomas @tpokorra schön dass du nen workaround hast, aber eigentlich komisch dass die rechte nicht passen. Der User im Container sollte ja nicht abhängig sein vom User außerhalb.

    @isotopp ich bin gespannt wie die GPU tatsächlich ausfällt. Laut https://social.treehouse.systems/@marcan/111327263751408213 sieht es ja so aus als wäre der technische Sprung nicht so groß, und als primärer maintainer vom Linux Support für die Kisten kennt der sich ganz gut aus

    Good news! My eyes are recovering and it sounds like oral steroids should prevent any recurrence. Also my retina specialist wants to see me again due to it being "an interesting case", so well done me.

    are there sata->usb adapters with full smart support (i mean i think there are but i am not sure how to look them up) or is this a limitation of my 2.5'' oem harddrives? also the transcend thing i have only reports 0°C status ok, no error logging support

    brot,
    @brot@social.tchncs.de avatar

    @milan those with usb attached scsi support should allow to access the smart status of the drives.
    Since I upgraded to proper controllers with UAS support, I had no problems backing up to a remote raspberry pi 4 with btrfs raid 1.
    (Even with the disks LUKS-encrypted and having zstd encryption active, rsync reports rates up to 50 MB/s. Modern SoCs are kinda magic)

    great, this host suffers from https://github.com/openzfs/zfs/issues/14005 again, after i was sure i had it resolved and dont know whats different here from other hosts... maybe i should use btrfs more.

    brot,
    @brot@social.tchncs.de avatar

    @milan btrfs serves the files on my personal nas since... 8 years at lower, and has survived a drive slowly dying twice. And on my personal laptop it has been the rootfs since 2011.
    Early problems have been lower performance, but that is an area where there has been constant improvement in the last few years and it is good now.
    I can't vouch for raid5 or 6, but other than that it has done it's job without being annoying :)

    @milan@social.tchncs.de avatar

    after i had to copy files to 40 cheap usb2.0 thumbdrives using rsync ... and sometimes multiple times as some files somehow got damaged, even with using sync command and checksum option and stuff ... i am never trusting that intenso brand again. just had to share a cloudlink as at least one person had almost all files damaged (not everybody got theirs yet).

    @milan one thing you could have tried is to create an image of a known good stick and dd it on the others. I had sticks (but mainly as cards) that managed to fail even then...

    (looking over the shoulder of a headmate) okay so what i am getting out of this is that Windows is basically unusable without extensive knowledge and use of group policies

    ... you can disable Windows Defender with them? and there's like fifty knobs to control updates?? holy fucking shit???? this makes it look like an operating system i would consider touching without hazmat gloves??????

    brot,
    @brot@social.tchncs.de avatar

    @whitequark yeah, I was quite amazed by the possibilities after having to learn how to set up a samba ad-dc and figuring out a group policy for the company.
    Windows sadly still is true to its core and managed to get me off the idea to use it for my main devices by getting into a "applying updates" bootloop in the first week of playing around with the GPOs on both my test computers (w10 and w11).

    Other than the bizarre pro-Series 60 Nokia story has anyone written any kind of story of how the brief glory period of desktop Linux on the smartphone in 2006-2010 caught fire and fell into the sea?

    brot,
    @brot@social.tchncs.de avatar

    @mjg59 I went drinking with the Ulm division of Nokia (who were working on meego) the day Elon fired all of them on a video call. If interested, i could ask if anyone wants to chat with you. Since I have not seen 95% of them since that day, I can't guarantee anyone will respond though

    as someone who dislikes NixOS for weird ideological reasons I won't go into (it's related to ABI-stable libraries), I have to say that I've been using NixOS for the last few weeks and it has caused essentially no issues despite me:

    • using it in anger (incl. literally)
    • only somewhat paying attention to the docs
    • having no prior experience with NixOS
    • or with the domain specific language it uses

    this is really impressive! props to all the people who make it happen

    brot,
    @brot@social.tchncs.de avatar

    @whitequark this might be the post to finally get me to give it an honest attempt. I read through the website and thought "concept sounds nice, wouldn't hurt to try this once I have time and do not need to recover from gestures wildly" thanks for mentioning it

    hmm the new machine has decreased performance, mostly noticable in php apps and when trying to jump into a container ... current theory is that it is because i chose zstd compression vs lz4 :/
    for the most part mastodon seems fine tho

    brot,
    @brot@social.tchncs.de avatar

    @milan is the zstd compression level adjustable? zstd should be comparable to lz4 when running at lower levels.

    @milan oof, bugreports concerning filesystems are always scary. At least those are "only" performance issues - although those can also bring down the complete infrastructure if severe enough

    I am once again encouraging people to reject the idea that terms of service should have any legal significance whatsoever

    brot,

    @mjg59 that is a clever take on the "oh no, big tech joins our safespace".

    @mjg59 All big tech wants is write terms of service, eat hot chip and lie.

    currently running a quick cleanup through the database to free some space in the hope to speed up a potential migration to a more powerful server (in case i decide to do so) – you may experience some slowdowns depending on the table that is currently being worked on (and the base load from the fediverse is already quite high). sorry for that :tchncs:

    brot,
    @brot@social.tchncs.de avatar

    @milan with that much ram i would recommend to try zram. Depending on the workload, it can be very much worth it. The 3 main servers at work have 256GB of RAM, and have 4x 20GB zram swap active. There is 22,5GB worth of swap in them, which only occupies 11GB. vm.swappiness is set to 30. This lead to lower iowait while having memory pressure and glusterfs doing its thing.

    annoying how there are times where i think the hw for this instance is enough or even slightly too much, then idk musk or maybe even spez say something and i am considering a server upgrade and wonder if what i have in the basket would be sufficient

    brot,
    @brot@social.tchncs.de avatar

    @milan I am running a 5 year old ex40, back when nvme was not available for such small servers. I am however still waiting for the recent drops in nvme costs to trickle down to hetzner as I would like to have just everything on SSD (including terrabytes of nextcloud stuff)

    milan, (edited ) to random
    @milan@social.tchncs.de avatar

    I think it's still going to be a while until it is relevant for our server(s) in particular, but if the new Meta project wanted to add us to their federation whitelist or just simply would open up its federation, would you as a user accept this to happen, assuming they moderate properly and the instance won't die due to load mid-term?
    :tchncs:

    brot,
    @brot@social.tchncs.de avatar

    @milan imo there are two aspects in that case: 1.I always encouraged everyone to use open protocols and oss to communicate. Never have all of my contacts been on the "cool" protocol (IRC, xmpp, signal, matrix) nor were those who did agree to get something "not WhatsApp" happy to change to the new cool protocol. Since matrix it has been easier to reach my contacts and I love that. Meta sure has the potential to add some more people on an open protocol. I have never been on any of their services.
