julianwgs,

Source?

julianwgs,

Dependency-free doesnt mean they dont have dependencies. Its just that they bundle them all in the executable. When there is a security vulnerability in a library on your Linux system the vendor of your distribution (Canonical, Redhat, SUSE) takes care that it is fixed. All dependent software and libraries are then fixed as well. All I say? Not the ones which have been bundled in the executable. First they need to find out that you are affected and then the maintainer has to update the dependency manually. Often they can only do this after there has been a coordinated release of the fix by the major distributors, which can leave you vulnerable no matter how fast the maintainer is. This is the way it is in Windows. (This was a short summary)

julianwgs,

Yes, in the sense that you are responsible to update the Docker container and often this can lead to vulnerable containers. No, in the sense that it is much easier to scan for dependencies inside a Docker container and identify vulnerabilities. Also most containers are based on Linux distribution, so those distribute the security fixes for specific libraries. All you have to is update the base image.

julianwgs,

Are you just starting out? I got started with home labbing with a Raspberry Pi 2B (1GB RAM!) and an external HDD I had lying around. I host Yarr, Navidrome, backups and a dashboard app Ive written on there and I am quite satisfied. I would really recommend starting small with hardware you already have and then buy new hardware as you go along. I am also using Tailscale. With this you can get your initial setup up and running in a day and save money if it turns out home labbing isnt for you or you dont really need the hardware.

julianwgs,

Free software as in freedom of speech, not necessarily as in free beer. Maintainers also need to pay the bills.

Steam Deck OLED Undervolt Efficiency and Performance Scaling (discuss.tchncs.de)

Hello, today I tested the performance and efficiency gains of my Steam Deck OLED at different TDP settings. As a benchmark i used 3DMark Firestrike. Which might not be the best benchmark for the Steam Deck, because it renders at 1080p. But you can still get good information from the results....

julianwgs,

Very interesting! Could you provide some summary of what the trends are or may be visualize the results? I am new to this kind of data

julianwgs,

No, it usually has 70% to 90% less CO2 emissions compared to fossil based fuel, because there are CO2 emitters in the supply chain: Transportation, heating, food for workers, etc. This is the same reason renewable energy has a small CO2 footprint as well. However for e-fuels you need about 6 times as much energy to go the same distance with an electric vehicle. So you have to build 6 as many renewables (only then do e-fuels make sense) compared to electric cars.

julianwgs,

Transport volume especially for a heavier electric truck is very important, because it is already limited by freight mass. There are already electric trucks for example by MAN on the EU market and the response seems pretty good. Not so much hype as everything Tesla does, though.

julianwgs,

There is plant-it written in Java and HortusFox written in PHP. Both using MySQL. Is there anything available which is written in Go or Rust and uses SQLite?

julianwgs,

Is the posted image from the time the article was published, so 9 years ago?

julianwgs,

This is one of these songs everyone recognizes, but only few know the song by name. Great share!

julianwgs,

I chose Navidrome, with which you can stream music from your hard drive. It has very easy setup and it feels just great to stream your own music. I use Tailscale to connect the server to my phone and Ampery as an iOS app.

julianwgs,

I bought Mirrors Edge: Catalyst. I really liked the original and doing a few runs from time to time is really nice

julianwgs,

Dont worry: The more data you share, the better the button becomes

julianwgs,

I once taught private lessons in math on calculating the area of a circle and I wanted to show the students how much cheaper per area a larger pizza is. So we of course got the diameters of pizzas from their favorite restaurant and started calculating. Then we found out that the normal sized pizza was actually the cheapest per area. It wasn‘t quite what we expected, but a very good math lesson for the attendees nonetheless: The owner lost money, because they were bad at maths.

julianwgs,

Nice! What prompt and model did you use?

julianwgs,

Well thats what backups are for, but may be start with a mirror or with unimportant stuff for at least a year ;) Also proprietary service can delete your data, too. This happens especially when you are using the generous free tier and they decide to make more money. See Evernote, Gitlab, Heroku…

julianwgs,

Growth has always been the biggest stopper for reducing environmental impact. Unfortunately there are a lot of countries which still want/need to grow their economy in order to have similar living standards as in Europe or North America. What Amazon demonstrated here is that it is possible to do this growth (9%) without increasing the carbon footprint (-0.4%). This unfortunately is not what everyone wants to read (including myself), but it is bitter truth of our global economy. (I know that this is a oversimplification and our planet does not care)

What’s debatable is that they don’t count the environmental impact of other companies products and their clients. I would argue it is more sensible to criticize these companies directly and may be let Amazon force them to publish the environmental impact on the product page. Of course if Amazon would care more about the environment than their bottom line they would act differently, but I don’t believe that…

Whats the worst is that they are destroying perfectly fine products. This is unacceptable and should be forbidden by law. Additionally they should get sued by the government for doing this thinking it was okay.

julianwgs,

Or make those secrets explicit. Tell them that you have a bank account on your name to which you only have access to and may be that you don‘t want to tell them how much money is in this account. Further tell them WHY you want that. Any reasonable partner would be fine with this.

julianwgs,

Yes, the comment was meant as criticism of the streaming era packaged as a joke

julianwgs,

It‘s 2023, you can still listen to the same shitty music, because it is yours to keep.

julianwgs,

It is also very resource efficient. I am running it on a Raspberry Pi 2 and it works flawlessly.

julianwgs,
  • Use sqlite instead of Postgres, MariaDB
  • Avoid enterprise software (Kubernetes, Elastic Search)
  • Only use projects with efficient programming languages such as Go, Rust, etc.
  • Try to run things bare metal
  • Lookout for projects which name themself minimal or light-weight

I use a Raspberry Pi 2 to self host a Dashboard written in Rust (Axum), a RSS reader called yarr and a music streaming server Navidrome. The latter two are written in Go and very resource efficient. The electricity bill should be under a Euro a month (6.4W max power consumption).

julianwgs,

I am actually kinda thinking about upgrading to AMD and then using the Intel mainboard as a server :D We will see
