Install Estonian e-ID Software on Qubes OS in a Fedora 32 VM

11 February, 2020 — Platschi

Update 03.11.2020: Updated Blog Post for Fedora 32 VM.

After receiving my Estonian e-ID, I have been asked to visit their welcome page to set up my new digital identity card. To my surprise, some Windows software is shown to be required in order for the card reader to function. No word on available Linux packages, no easily discoverable information in the FAQ to lead me to the right place. So here we go!

F-Droid repository for Trustroots

20 February, 2019 — Platschi

There are happy folks out there that do not (wish to) use the proprietary Play Store to receive their (android) phone applications from. A great alternative is F-Droid, "an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform".

Due to various technological reasons, the Trustroots app currently cannot be integrated into the "official" F-Droid repository. But fear no more, F-Droid by design has been created to allow everyone to create and use their own repositories full of apps they prefer to use. How awesome is that?

Platschis Blog available via Hidden Service

13 January, 2017 — Platschi

In an attempt to learn more about the Tor Project, I've set up a hidden service for this website of mine. Readers (if any) that surf the web with the Tor Browser are welcome to connect to this page from now on with the *.onion link below.

If you have issues verifying the document below, try it with this file.

Hash: SHA512

Platschi's Blog		http://w4uxllvpgx3mmngddhjrzkktpskpulicic3wmlntvfx2cl45ycefxrad.onion (port 80)



How to verify

When on a Linux machine, open the Terminal. Download the file and my PGP Key with:

$ wget
$ wget

You might need to download wget beforehand. Alternatively, you could use curl.

After downloading the files, import my PGP Key to your keyring, then attempt to verify the file:

$ gpg --import platschi.asc
$ gpg --verify hidden.txt.asc

Now, if all went fine, you should either see that I signed the document above with my PGP Key, giving you some little extra confidence that it might have been (probably) indeed me putting that link up there. That is, if you trust my PGP Key for what it's worth.

gpg: Signature made Fri 29 Jun 2018 07:08:25 PM -03
gpg:                using RSA key A7433BD99150AE38408D4547D76D9EB36B20DB71
gpg: Good signature from "Ralf Platschkowski " [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: A743 3BD9 9150 AE38 408D  4547 D76D 9EB3 6B20 DB71

Feel free to contact me if you have questions. More to come in the not-so-far future!

The road to immigration in Uruguay

07 September, 2013 — Platschi

"Uruguay is one of the few countries in the world, where it is still easily possible to immigrate."

Phrases like these, or similar, one can find plentyful all over the internet. Indeed, it seems easy to get a residency or working permit for Uruguay, but unfortunately, bureaucracy is always just a stone's throw away. At least, we have to admit, there's barely any physical fighting included, unlike in Moldovan offices.
