It feels like traveling to conferences in Europe has significantly gone up in price.
I just looked at train tickets to Paris. Twice what I paid pre Covid.
Italy? Either fly with a short stop in Romania (makes sense, right?) or 4x with the train what I would pay for fuel when driving.
I’ve flown to Boston for less than what I’d pay to get to Portugal.

I’ve been using Jellyfin for 5 or 6 years.
Plex is steering towards entshitification for a few years now.
I’m on the edge of buying a Plex lifetime pass and hope for the best, knowing I’ll be disappointed in a few years.
I want podcasts and music without hosting two more apps. I want a reliably stream encode (I still have Jellyfin choke on some 4k transcodes despite the 3060ti in the box). And don’t get me started on client UIs. There’s a reason I’m paying for Infuse.

As I’m not a regular on the Discord server I don’t feel strongly about any option, but three thoughts.
1. I don’t think the change should impact Django’s server as we aren’t flagged as NSFW server. So no one needs to do this. Or do we regularly do streaming etc in there?
2. Matrix was a nightmare to use, we ditched it for Delta Chat and no one ever regretted this (~ 32 people). Delta isn’t a good alternative here.
3. Using an OSS platform for an OSS project “feels better”.

First mail server migrated from Stalwart to Mox.
I think I’ll have to double check the configuration. I would have expected the mailboxes used for reporting and listed in the DNS entries Mox generates to be created automatically which doesn’t seem to be the case.
Otherwise things seem pretty decent. I like that the admin interface uses port forwarding via SSH instead of being exposed to the Internet.

Two KVMs to test. The USB one is mostly to not carry around a monitor every time I need to do something on hosts without one. The over IP one gets a proper test run and if it works I’ll likely order a pack of 10.

Hm, our boiler room is right on the other side of the server racks. I might put all the UPS there and pull a few cables through the wall. Not ideal, but the 3000VA UPSs are noisy. And the boiler room is technically designed for things going wrong and being on fire in a worst case scenario.

What are we using these days as bare metal hypervisor for Windows, Linux and BSD guests?

Our internal service host alone is now at 20 docker compose stacks, it is slowly getting tedious to update all of them.
So I did the only logical thing - ignore everything I know I should be doing (and do in production) and simply yoloOPs it with a bash script :D

I decided to look into the overhyped language that looks like Perl got sick on top of C again now that some years passed and I must say the pretentious borrow checker at least decides to spit out helpful errors.
The community seems to have shifted away from “insufferable elitist” a long time ago, so that’s great.
I have an IoT project coming up and implementing the service in Go would only take around two days. So I might use this as an opportunity and give #rust a proper chance.

Ordered a replacement keyboard with US layout for my Lenovo X1 Carbon. The service manual to swap the keyboard spawns 20 pages. You have to start at the bottom cover and literally remove *everything*.
I remember swapping a broken keyboard on an IBM T20. 2 screws and two plastic clips. Not even 5 minutes of work.
The X1 is lovely. It’s ultra portable. But right now I wish I’d be carrying a brick with the build quality and service characteristics of old IBMs. #lenovo #ibm #thinkpad

the refesh rate depends on the screen, the GPU, the driver and the connection between screen and GPU.
There’s a chance that your GPU only supports 60Hz at the resolution of your monitor. It might also be limited by the cable.

Delta.chat seems pretty neat and one of the few times PGP is implemented in a user friendly way.

I’m slowly but surely annoyed enough by Matrix, MAS and Element (X) that I might just nuke the server and tell people to send me an email or something.
ElementHQs feels actively hostile to small scale self hosting while working on their “government enterprise optimizations” agenda.
I’ll have to look into sane alternatives that are usable by non technical folks which also support OIDC. Any recommendations? *good* mobile clients on iOS and Android are a requirement.

I’m using Ollama to host LLMs (so llama.cpp underneath)
- system memory is usable
- if the model cannot 100% be offloaded to the GPU it’ll offload the maximum number of layers that fit in VRAM
- the GPU utilization goes down to 15-30%
- CPU utilization sits around 60%
A 32b model Q8 uses the 22GB available on the 4090 and 15GB system memory.
A response for 132k context takes about 3 minutes.
Same model, Q4 fully offloaded to VRAM 19s.

If the identification works I’d love to release the service and have all instances add to a central block list.
But I have the strong feeling that a shared block list will simply end in abuse. Crawlers honoring robots.txt will be blocked by people adding them to the list because they disagree with the company owning the crawler.
Basically the fate of any shared block list with random people being able to add entries to. :/

2025-01-21 08:56:11 UTC

A small project is coming along just fine. A service to handle a specific path.
Basically a hidden (not displayed to the user) link on a website disallowed in robots.txt.
Visit the link and the connection is kept open till the crawler times out.
Crawler UA and IP are stored.
Second request from this combination 50ms before the timeout start streaming /dev/random or something similar.
I still need to test how links like this behave with screen readers etc bot to accidentally mess with someone.

I’ve been running my own matrix server for private and business for 6-7 years. If I could make the call again I’d setup a Jabber server.
The UX of Element is atrocious. And new features supposedly fixing some of it is playing whack a mole across multiple GitHub issues, a new services / app.
Synapse is a resource hog and Element decided to optimise it for paying governments because “regular users don’t need it”.

Self hosting email kind of works decently well, but requires a good amount of attention for the most stupid reasons.
I’m inclined to join the “email is broken and it’s over crowd”. Pay someone else to make it their problem and keep usage to an absolute minimum. At least for business use.
I might setup a small inbound only system for spam and test mails.
