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?

Angenehmer Surfen im Web mit Firefox

29 January, 2019 — Platschi

Der Mozilla Firefox ist ein freier und quelloffener Internetbrowser. Trotz einiger Macken immer noch zu empfehlen, erst recht im Vergleich zu den anderen Alternativen wie Chrome oder dem Internet Explorer.

Nach erfolgreicher Installation gilt es meistens, erst einmal einige wichtige Standardeinstellungen zu ändern sowie zwei wichtige Add-Ons zu installieren. Achtung: Die Einstellungen können je nach Version und Betriebssystem leicht anders aussehen. Als Vorbild habe ich eine frische Windows Installation von Firefox 65.0 genommen.

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: WARNING: This key is not certified with a trusted signature!

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!

Einführung in den Datenschutz

11 October, 2015 — Platschi

Über die Jahre hinweg wurden Nerds belächelt, deren Theorien als paranoider Quatsch abgetan. Dieser Quatsch hat sich schlussendlich, spätestens seit Edward Snowden größtenteils für wahr herausgestellt. Kurzum: Geheimdienste und Staaten dieser Welt bauen seit Jahren eine weltweite Massen~~überwachung~~kontrolle auf, von der die Stasi zu Ihren besten Zeiten nicht einmal im Traum dran gedacht hätte.
