I can't imagine the sound of a room with like 20 pupils, each hammering on such a keyboard.

I too am now the proud owner of an IBM Model M. (postit.quantentoast.de)
 

When 4 IBM Model M keyboards showed up during a cleanup at work (university) and I was asked if I wanted one, I of course said yes!

It's an IBM model M 1394540 from 1992 with the PS2 connector and the detachable cable. The keyboard and cable are in very good condition, even the manufacturing sticker on the back looks pretty good! All keycaps present, all keys work. It just needed "some" cleaning which ended in a 3h long process haha.

It will definitely be my daily driver for the next few weeks. I haven't decided yet if I will use it long term. I'm actually very happy with my modded Keychron Q6. Maybe I'll try some lube on the stabilizers and perhaps a little tape mod.

The best part was that I got to take a second Model M with me, which I will give to a good friend. This one is also in great condition.

It was an incredible day!

Tuya Smart Plugs (Wifi) - ESP Firmware Tasmota (postit.quantentoast.de)
submitted 11 months ago* (last edited 11 months ago) by [email protected] to c/[email protected]

Aus vergangener Zeit hatte ich noch zwei W-LAN Steckdosen der "Marke" Aisirer herumliegen, welche Software von Tuya verwenden. Da ich keine Smart Home Geräte verwenden möchte welche nur mit Cloud-Anbindung - und erst recht nicht mit zugehöriger Software aus China - funktionieren, habe ich recherchiert wie man den in den Steckdosen enthaltenen ESP flashen könnte.

Das erste Problem: Die neuen Modelle der Steckdosen nutzen gar keine ESP Module mehr. Glücklicherweise gehören meine Plugs nicht dazu.

Für manche (ältere) Tuya Geräte kann ganz einfach Tuya Convert genutzt werden um eine andere Firmware zu flashen. Damit ist kein löten notwenig.

Leider war die Schwachstelle, welche Tuya Convert ausnutzt, bei meinen Geräten schon geschlossen, weshalb doch nur noch löten blieb.

Das Tasmota Getting Started ist sehr ausführlich und bietet eine gute Grundlage. Gerätespezifische Daten wie beispielsweise das Pinout muss man aber anderweitig suchen, sofern das eigene Gerät nicht in der Liste bereits vorhanden ist. Erneut hatte ich Glück, denn in einem Issue #4286 hatte jemand anderes bereits genau mein Modell zerlegt und erfolgreich geflasht.

Zum flashen habe ich mich entschieden den Tasmotizer zu verwenden, da der Web Installer und die nötigen Berechtigungen sich nicht einig wurden. Einfach der Anleitung folgen, den aktuellen Tasmota Release ziehen und flashen.

Danach alles zusammen bauen und fertig. Beide Steckdosen funktionieren einwandfrei. Einziges Mankerl: Die Gewinde, welche die Plastik Abdeckung halten, sind sehr sehr empfindlich und brechen auch bei größter Vorsicht ab. Die Abdeckungen halten dennoch gut, auch wenn sie nur leicht, oder gar nicht mit Schrauben befestigt sind.

Die Steckdosen können nun über die HTTP API oder MQTT gesteuert und in Home Assistant eingebunden werden. Yay 🎉

Gumb is not GDPR compliant - Meeting Manager for Communities (postit.quantentoast.de)
 

GDPR Compliance Check

For those who haven't heard of it before, Gumb is

A platform for managing meetings, gatherings, and events for communities of any size. - gump.app/en

I have investigated this app because it is used by a club where I am occasionally active.

Landing Page / Homepage

Fonts: The landing page is using google fonts, so those fonts are loaded (8 requests) from fonts.gstatic.com when opening the website. The first issue here is that google fonts are not listed in the privacy policy at all. Second, by a German court ruling google fonts are not compliant with the GDPR:

The use of external font services cannot be based on Art. 6 § 1 p.1 f GDPR, as the use of the fonts is also possible without having to establish a connection from visitors to external servers. - LG München Az. 3 O 17493/20

Images: Furthermore the website is loading images from firebasestorage.googleapis.com (105 requests). Following the argumentation of the previously mentioned court ruling, using firebase for images could also be considered non-compliant because images could easily be served without having to establish a connection from visitors to external servers.

Youtube Embed: The website includes a youtube iframe (13 requests to www.youtube.com) with an introduction video. While youtube themself offer an iframe option called "Enable privacy-enhanced mode", the Gumb homepage embeds the »normal« iframe that places tracking cookies which again violates the GDPR. The iframe furthermore sends

  • 6 requests to play.google.com/log,
  • 4 requests to https://googleads.g.doubleclick.net
  • 1 request to https://static.doubleclick.net
  • 4 request to https://jnn-pa.googleapis.com

Tracking: The website uses, as stated in their privacy policy, Google Analytics (GA) which results in a request to https://region1.analytics.google.com/g/collect... and https://www.googletagmanager.com. However, writing "we use GA" in the privacy policy is not sufficient. GA requires consent from the website visitor.

There are a few more unnecessary requests, but I think the point is clear.

All of that is happening without any consent from the visitor!

Mobile App

Gumb offers mobile Apps for Android and iOS, of which I only checked the Android version. While I can't say for sure that the app violates the GDPR because it immediately asks for credentials, the Exodus Privacy Report (of the latest version 1.0.84) still looks rather bad:

  • Amazon Analytics
  • Amazon Mobile Analytics
  • Google Analytics
  • Google CrashLytics
  • Google Firebase Analytics
  • Google Tag Manager

Web App

Next to mobile apps, Gumb offers a web app too. Well, what can I say - there are requests to

  • https://fonts.googleapis.com
  • https://www.googletagmanager.com
  • https://region1.analytics.google.com/g/collect...
  • https://www.google.de/ads/...
  • https://stats.g.doubleclick.net/g/collect...
  • https://ipgeolocation.io/

even without being logged in or any given consent.

Conclusion

For a tool from Switzerland with paid subscription plans and the purpose of managing events/meetings etc. it uses a lot of google (tracking) services... Very sad to see as the app looks otherwise really modern and useful. Do today's developers know that applications like Gumb can be implemented without selling their users' soul to google?

Nice, thanks for sharing! Mine looks like this atm:

  • HS: Mainly Docker containers and VMs
  • VPS: Wireguard to relay traffic (NAT) to the HS (SSL termination on HS)
  • UPS in case of power outage
  • Pi4 for backups within the local network. It also has a disk station for regular air gapped backup.
  • Pi3 for off site backup
  • Fire extinguisher nearby in case of emergency ^^

Starting my Self-host journey and need a little [Help] to start in c/[email protected]

Been there, done that. Volatility is something you learn pretty early, yes. ^^

Starting my Self-host journey and need a little [Help] to start in c/[email protected]
[–] [email protected] 6 points 1 year ago (2 children)

First: Good for you, enjoy the journey! Second: Just as others already pointed out, Mastodon is not really a beginner project. You want to understand what you are doing, not just make everything work no matter what. Some reasons why I'd not start with Mastodon:

  • Complex deployment stack (for beginners)
  • Needs regular maintenance
  • Security considerations (if you haven't managed/hardened a server before)
  • Long term project

So instead: Have a look at awesome-selfhosted for ideas. A personal dashboard, photo gallery or a PiHole/AdGuard is a good start.

About Docker; it's a bit more than just dependency separation. It's a kind of virtualization, but without each container running it's own kernel. Advantage is: Docker images run (with some configuration) relatively lightweight out of the box. So there's no need to install the applications natively. While I'm a great fan of Docker, you'd probably learn more installing things natively in the beginning. Or maybe do both, it's up to you. However, if you decide to use Docker, be sure to understand what's going on under the hood. That's where the fun begins. Everyone can pull and start images, but not everyone knows how to customize or build them themselves.

No matter what you decide to do, have fun. And if you've any questions, there's plenty of documentation online or just ask. The selfhosting community is very welcoming towards new members ;)

Lemmy Image Fix for Tor Mirrors in c/[email protected]
[–] [email protected] 1 points 1 year ago

Small Update: When uploading images from the tor mirror, they are stored in the DB with the onion address. One workaround I'm currently applying is running a script periodically that updates image links. It looks like this:

UPDATE post SET url = REPLACE(url, 'http://your-hidden-address.onion', 'https://your-clear-domain.tld')

And btw all this is for version 0.18.3 (to avoid confusion in the future)

[Solved] How can i host my own lemmy instance just for myself on a single raspberry pi 3b+? in c/[email protected]
[–] [email protected] 1 points 1 year ago (1 children)

Don't worry, nothing is easy in the beginning and yes, some docs are not up to date because Lemmy has such a steep development curve and therefore frequent changes.

[...] i think i might try to do it again tomorrow after the frustration of failure of today is gone and i have some more motivation.

Do have any other self hosting experience? Maybe a software that is a bit more easy to handle would be a good starter. With that, you can experiment and learn a bit, before starting a (long term) project that requires proxy, database, frontend, backend and configs to make them work together. Not to speak from the maintenance.

Is it okay if i just ask my questions to you directly in this thread?

Sure thing. I can recommend the Lemmy admin matrix chat as well (if you're a matrix user).

Do you mean DynDNS with the automatic updates?

What I mean is: best case is your provider offers an api which allows you to update the DNS records by running a simple script. What I would not recommend is using something like mylemmy.dyndns.org (or similar services) for a Lemmy instance.

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago) (3 children)

Since your question is quite basic and general, I'll try to answer equally.

  1. Hardware: For a single user instance a Pi 3B+ is sufficient. Still, Lemmy can take up some storage space over time because of the images. So make sure you don't take the smallest SD card you have lying around. I assume you know how install an OS and get basic things running.

  2. Get a domain; there are many providers out there. Consider using a TLD of your country (e.g. .de, .fr). Domains are usually relatively cheap. You're most likely running your Pi at home, so check if you have a static IP address or if you have a dynamic one. First one? Great, go ahead. Second one: Check if your domain provider offers an API to automatically update the DNS record; example provider api.

  3. Have a look at the Lemmy administration docs. Depending on your experience, it is relatively easy to setup. Make sure you understand what you're doing, i.e. first get to know Docker for example, then follow the commands. If you don't understand something, just ask or search online. Lemmy is not very complex to operate, so for every part of the deployment you should be able to find information online.

  4. Set up port forwarding in your router for ports 80 (HTTP) and 443 (HTTPS). You can find information for your specific router online, but for some routers this cannot be done.

  5. Get a SSL certificate for your domain. You can get one for free with Let's Encrypt.

  6. Once you have your instance up and running, I would recommend setting it to "private" first. This way you can play around with your instance or reinstall if something goes wrong without having to worry about federation. Once you've federated (communicated with other instances, e.g. by subscribing to communities of other instances), you really shouldn't reinstall!

I hope this helps you with the first steps. Decide for yourself if you want to deal with maintenance and administration "long term". It's perfectly fine to use other instances and not host Lemmy yourself if you don't feel up to it. After all, there is also a security aspect to consider. If you do: have fun with self-hosting!

FBI Seizure of Mastodon Server Data is a Wakeup Call to Fediverse Users and Hosts to Protect their Users in c/[email protected]
[–] [email protected] 4 points 1 year ago

That's an interesting question. At the time being, I think the only way is to do regular backups and store them at a friends for example. That way an instance can be restored after the server has been taken.

Really the only way is to not save anything, or perhaps some sort of blockchain for all the comments and posts?

Blockchain is an interesting thought - or maybe something similar to Matrix. All instances have their own copy of a post and sync with each other. That way it doesn't matter if one instance disappears. Though, that would probably not comply with the Fediverse idea? Interesting thought experiment non the less!
