VeraCrypt and Panfrost compile vs 1GB memory

November 10, 2020 Technical Ben Zucker

Recently I needed to build mesa on my OrangePi One Plus to get the most out of the current Panfrost support. However the building always failed because the board locked itself up. Some research showed that it most likely ran out of memory.

A bit later I tried building VeraCrypt on a NanoPi Neo3 and after a while run into the same issue.

Armbian does ship zram with each board to get help get around the memory lacking a bit. However in these cases it simply was not enough.

Finally...

…moved to a fresh VPS using Debian 10 as OS. Also IPv6 is now configured and available.

The mailserver stuff has been discarded. Too much effort to maintain for way too less throughput.

What??

Sending a message to a webmaster with his public key… The idea behind this I actually got from an April fools released by c&t magazine. To cut a long story short they claimed that weak GDPR phrasing could be a reason that common letter post might need to be properly encrypted. They even provided a tool that extracts a websites public key use it to encrypt a provided message.

You can find the article (in German) here and the tool here.

Anyway. I was thinking how I could use this to send webmasters encrypted messages when they do not offer public keys emailing. And for some reason I do not was to ask them for keys. Maybe because I am incredibly clever and shy at the same time … never mind.

Some basics

To get a basic understanding how symmetric and asymmetric encryption - to say the relationship between public and private keys - works just watch this video. I started adding captions in English. Hopefully they will be released into the wild soon.

THX @dunkelmunkel Feel free to watch more of his videos 😉

Probleme der Welt

Beitrag vom Juni 2007

Die Welt hat sich in den letzten Jahren schon stark verändert.
Vor 50 Jahren hat noch keiner an Terrorismus gedacht.
Vor 50 Jahren hat sich noch keiner so wirklich Gedanken über Supercomputersysteme gemacht.
Vor 50 Jahren hat sich keiner Gedanken über die Begrenztheit der weltweiten Ölvorräte gemacht.
Vor 50 Jahren hat sich niemand Gedanken über eine einheitliche Währung in Europa gemacht.

Es gibt nur eine Gemeinsamkeit: Es hat damals [scheinbar] alles funktioniert. Wenn du keine Probleme hast, mach dir welche….
