Solar LLM server V2 is coming along. There is still a lot to do, but I'm at the point I can run a basic Strata test.

EDIT: 28 tokens per second achieved with Strata's QWEN 3.8 120b model.

Remaining to do:
-The 4x 500GB Velociraptor HDDS land today, so I can replace this single with that RAID0 array to speed up load times.
-Tend to the GPU power delivery cables, clean them up.
-Install the custom GPU cooling system speed controller and high velocity fans.
-Install the rest of the software stack - Hermes Agent, Unsloth, Netbird, etc.
-Stress test it, measure performance and power, tune the software stack.
-Let r rip!

This photograph shows an open-air computer server or mining rig built on a black metal frame resting on a wooden surface. Inside the rig, a Topower power supply unit sits prominently on the left with a glowing green "Power Good" indicator light, connected by a tangle of black power cables. Several graphics cards equipped with PCIe riser cards and black shrouds are installed vertically in the center. A large, white ring-styled cooling fan is actively spinning on top of the components, while two additional black case fans are mounted on the front right side of the frame. In the background, a beige computer monitor displays terminal text, accompanied by matching vintage beige desktop speakers.

    New blog by me:

    I'm running Proxmox Backup Server using Backblaze B2 (an S3 compatible object storage service) for storing backups. This does work fine, but my scheduled verification (I verify once a week) regularly fails on some backups due to what appears to be transient issues with the B2 API.

              Heute kam ein Löschantrag. Er war ein vorformulierter Paragrafen-Marathon mit Art. 17, Art. 12, Art. 19, Fristsetzung und der Androhung von Beschwerde und „rechtlichen Schritten“. Ohne Nutzernamen und ohne Namen, nur mit einer Alias-Adresse.

              Eine kurze Nachricht wie „Hey, bitte lösch mein Konto“ hätte gereicht. Das hätte ich in zwei Minuten und mit einem Lächeln erledigt.

              Verstehen mich nicht falsch: Das Recht auf Löschung ist wichtig und gut so. Aber nicht jede Anfrage muss wie ein Rechtsstreit klingen. Vor allem nicht bei ehrenamtlichen Projekten, die ohnehin das Beste aus ihren Möglichkeiten machen.

                    Windows doesn't fail over between DNS servers deterministically, so a secondary DNS bypasses your filter. DnsAutoSwitch keeps one DNS server and switches it: primary while it answers, router when it doesn't. Hold/pause files, logs. MIT, release zip, no runtime needed.

                              These daily backups from Proxmox's backup server may have saved my data.

                              When the mysql container is running, data is written to the filesystem. If I set this up properly, this would be on a persistent volume, so that it persists across restarts/shutdowns/etc.

                              In my case, because computers will do what you tell them to, the mysql data ends up being written locally to the k8s worker node. This lives in the dir /var/lib/containerd/io.containerd.grpc.v1.cri/containers/<random-id>/volumes/<lvm-label>/var/lib/mysql/.

                              Before I found that path, I figured the data had to live somewhere, and Linux can get pretty creative with mount paths, so I went looking. Based on binary text searches with xxd, and finding references to lomo soltado, I've found it. Other recipes also seem to be in there that I know I had stored.

                              Recovering the data from the files will be an exercise for tomorrow. But I feel a lot better about it now.

                              Screenshot of hexadecimal and ASCII output from a command line, showing that I have successfully found the text matching lomo soltado, a recipe I was looking for in a database file.

                                Does anyone have a browser bookmarking system they swear by? I research and read a lot for work and my own interests and I am both a tab and bookmark hoarder and it is a Problem. My saved links span sites, articles, images, videos, technical documentation.... you name it.

                                Preferably something I could but open to considering paid services if they fit my criteria well enough.

                                I cannot dedicate time to sorting, tagging, or otherwise organizing links - I have tried it before and always commit to it for a day and then get overwhelmed by the sheer quantity. Or I get stuck in a cycle of constantly optimizing my tagging/folder system. There is no in-between.

                                Has to be low-friction to save a bookmark but I also need some search functionality for sifting through links to find what I need.

                                Ideally I could see what links I use frequently vs less frequently for occasional pruning.

                                I've considered building my own app for this and have various prototypes in different stages of disarray. Just wondering if there's anything out there I should give a try before possibly re-inventing another wheel specifically shaped for my brain.

                                            Any helm charts you like?

                                            Any images you like?

                                            Any particular servers or clients you like?

                                            Any security steps you take?

                                            Any fancy crowdsec rules?

                                            Please do not suggest anything LLM/AI related. I'm not interested. If I wanted that, there's an ocean of slop out there.

                                            Update: getting great server suggestions, please keep em' coming! Also interested in TUIs, desktop apps, web mail, and android apps :)

                                              So, based on all the replies here, on lobste.rs, and in anti-ai spaces, I've compiled an issue on my forgejo to start parsing what I want to try for myself as well as what I might offer as a service down the line. It mostly just categorizes links to all the things and adds super brief comments selected from here and lobste.rs so I can take everything into consideration on various categories of things to offer, in addition to just fun treats to try myself (like CLI/TUIs).

                                              You can check it out here:

                                                I'm seriously considering moving off GoToSocial to a regular Mastodon instance.

                                                I've self-hosted for a while now, and it's generally good.

                                                But there's a few things I miss.

                                                The first is being able to search widely for posts on a particular topic.

                                                Yes, relays help, but there's a big tradeoff: The more relays you have, the more storage you need.

                                                I miss seeing posts from Lemmy and some other Fediverse apps that don't quite work with GtS.

                                                And then storage becomes a bigger factor over time too.

                                                  So now I need to move my . And I have two options:

                                                  1. Migrate reverse proxy from to (no documentation on this around the internet except uncertain assumptions).
                                                  2. Pay x4 for the internet for a business plan, where I’ll be able to rent more than one static IP.

                                                  So the question is do you, dear , have a working example of Caddy config for Mastodon?
