adafruitKa-BOOM! AS3935 lightning sensor can detect storms before they hit
We designed this breakout in 2013 and it's finally seeing daylight... just in time for thunderstorm season ⛈️💻
Martin KirchgessnerI've always thought YubiKeys are expensive and too easy to loose or forget, so many thanks @Foxboron for ssh-tpm-agent ! I already had per-laptop #ssh keys, now they're sealed with its Tusted Platform Module (and a much shorter pass)👌

Store ssh keys inside the TPM: ssh-tpm-agent
After writing age-plugin-tpm a friend of mine at the hackerspace was super excited to finally have easy file encryption with TPM sealed keys, all without having to rely on gnupg. “This is great!” he said. “I wish I could have my SSH keys sealed in a TPM just as easily”. We should have left it at that. I shouldn’t have replied with a random assortment of facts like “I know google/go-tpm now”, or “but Go has a ssh-agent protocol implementation” followed-up with “Filippo has already implemented yubikey-agent, it can’t be that hard”. So I wound up writing a new ssh agent.
Meduza in EnglishJournalists have unearthed a scientific paper trail connecting the rare toxin used to kill Alexey Navalny to Russian labs implicated in the 2020 attempt on his life. https://meduza.io/en/feature/2026/02/25/scientific-paper-trail-links-the-neurotoxin-used-to-kill-alexey-navalny-to-the-same-russian-labs-implicated-in-2020-novichok-attack
Scientific paper trail links the neurotoxin used to kill Alexey Navalny to the same Russian labs implicated in 2020 Novichok attack
The same Moscow-based research center linked to Alexey Navalny’s 2020 poisoning — SC Signal — also played a role in synthesizing the toxin that killed the opposition leader, according to the investigative outlet Agentstvo.
tntIf you're a swiss resident ( or know one ... ) you can get a custom hardware design onto an ASIC for FREE !!!
You get back one chip with your design (and a bunch of others!) and some board to help bring up/testing.
Also, this is "resident", no need to be a student or at uni or anything, you just need a valid Swiss address ...
I know I might be repeating myself here because I mentioned it a few month back but this bear repeating IMHO.

Erich M.Am Wochenende war der #NomenNescioClub in "Liberation". Leider hinter der Paywall. Hat wer 1en Account & könnte 1 PDF machen? @rigo ?
Heute hatten der t1m & me einen längeren Termin in Wien sozusagen mitm angelsächsischem Mediensprachraum.
concretedogKLAXXON! #SOURCE issue 4 "Airwaves and Airplanes" is out! Good grief that's taken a while! Anyway in this issue we have a beginners tutorial for the fabulous @gnuradio we also get started with #OpenVSP which is #NASA's #opensource vehicle sketchbook and it's rounded out with a look at a new @FreeCAD workbench, Detessellate which helps reverse engineer Mesh to #CAD files. We've also tweaked a few things on the website! https://sourcemag.co.uk/

Samuel BrinkmannIhr möchtet basierend auf OpenStreetMap-Daten im Browser einfach Poster oder Postkarten erstellen? Dann hat @vr_alex89 am Wochenende etwas für euch gebaut:
https://poster.54gradsoftware.de/.
Je nachdem, wie viele Menschen auf dem Server sind, kann der Vorgang auch ein wenig länger dauern. Für die nächsten paar Monate werden wir den Server auf jeden Fall betreiben.
Die Idee dazu stammt von https://github.com/originalankur/maptoposter, allerdings gibt es ein paar mehr Einstellungsmöglichkeiten und eine WebGUI.
Hier ist ein Thread mit einigen Beispielen der größten Städte in Deutschland.
P. S.: Wir von @54gradsoftware freuen uns immer über spannende neue Kontakte und Projekte/Aufträge.
GIMPOur third release candidate for upcoming #GIMP 3.2 will feature a new splash image, made by astronomer @markmccaughrean (as were the first 2 RCs' splashes),
This #JWST image shows "a protostellar outflow complex called HH288, which we nicknamed The Dragon Jet some thirty years ago when we first discovered it using ground-based telescopes".
Enjoy!
