In discussions about clean Hydrogen, there is a popular idea floating around, particularly in countries like Germany or Japan that import large parts of their current fossil fuel energy. Instead of importing fossil fuels, the story goes, we will import large quantities of Hydrogen in the future from places where wind and sun are plentiful, and therefore, renewable energy is cheap. The problem with this idea is that Hydrogen is really difficult to transport. ⚡💧🚢🏭 🧵

Hab mir gerade eine Rede der Linken Spitzenkandidatin Heidi Reichinnek auf youtube angeschaut, die ja scheinbar gerade dafür sorgt, dass ihre Partei noch eine Restrelevanz hat. Als erstes spricht sie über den Rechtsruck und Rassismus. Jetzt würde man ja denken: Linke Partei, die sich als zentrales Thema gegen Rechtsruck und Rassismus wendet, ist eigentlich selbstverständlich. War es halt für die letzten Jahre meist nicht.

Webdesign tip: SVG files are smaller in practice than it may appear. If you use an image on a webpage that you have as a vector graphic, it's usually a good idea to use SVG instead of raster formats like JPG/PNG. Given high resolution displays and zooming habits, your width="[pixelsize]" is practically not what's displayed, and it'll look better if it can be zoomed without losses. But if you're an optimization perfectionist, you may look at file size, which can be misleading. 🧵

I am regularly surprised how many organizations fail with one of the most basic things they can do about IT security: HAVE A SECURITY CONTACT. If someone externally wants to tell you about a security issue, make it easy for them. There's a standard for it (security.txt), but even having any place on your webpage saying e.g. "if you found a security issue, please contact XYZ" is good enough.

Es sagt ja so viel über den kaputten Stand unserer gesellschaftlichen Diskurse, dass wir gerade eine Diskussion über den Krankenstand haben, aber kein einziger Vorschlag dazu zielt darauf ab, dass Leute weniger krank werden. Ich mein, ist ja nicht so dass man da nix tun könnte. (Luftfilter, Masken, Homeoffice, leichterer Zugang zu Impfungen, ...)

Ach echt, es war gar keine tolle Idee, die Heidekrautbahn mit Wasserstoff (wohlgemerkt aus Erdgas) fahren zu lassen? Hätte uns nur jemand gewarnt!

Wasserstoff-Engpass führt zu Einschränkungen bei Regionalbahn

Auf der Strecke der Heidekrautbahn zwischen Berlin und Groß Schönebeck fahren seit Mitte Dezember Züge mit Wasserstoffantrieb. Damit ist nun vor...

Anyone has an explanation how that happened? I got an error about a double free in an ssh shell with an immediate disconnect afterwards. Likely a memory corruption happening in bash. Possibly also in ssh itself...

This is quite something: The BBC reports about health misinformation. One example is... a show on BBC! I mean, I guess it's good that they critically evaluate their own reporting. But it gets better: "A spokesperson for the BBC declined to comment." That's quite arrogant of the BBC to decline to comment when a journalist working for the BBC asks you for a comment

Dear everyone who owns domains that are *not used for e-mail*, particularly ones that are potential targets for phishing (banks, high-profile names): Could you please configure SPF+DMARC, ideally with p=reject? You may wonder: Why should I configure anything email for a host that isn't used for email? Well... it helps others to identify spam sent with your domain as the sender.
