Free sunday tip: if your #esp32 refuses any flash upload or erasure, check you don't have a serial monitor running in a random terminal...
At @logilab we have deployed 5 @peertube instances over the years :
1. intranet from source
2. intranet using @yunohost
3. extranet using yunohost again
4. public for @semwebpro conference using yunohost
5. public for logilab videos using kubernetes and s3-type storage
With this new kubernetes + s3 deployment we're trying to contribute and have feedback from other users or potential users. You can review https://forge.extranet.logilab.fr/open-source/peertube-on-kubernetes and get in touch ! Thanks ! Boosts welcome.
The ref voltage is a bit off (6.0v) but well within the required range (+/-0.3v). After a quick adjustment, it's starting to look better
But it was pretty unstable, mainly because the 2DW233 was drived too low with current schematic: at 1.5 mA instead of the expected 7.5mA (for the 233). So I played a bit with ltspice to find better values for R61 and R63, and I also replaced the opamp with a 741 I found while cleaning a bit my bench :-)
So here is current situation: the 5.9v zener reference has been replaced by a 2DW233. First quick check was a bit dodgy: this ref is normally 6.2v, but actually consists In 2 zener head to head, so in practice a 5.5-ish v zener in series with a forward one (so .6-ish v). So I've used only one of the zener of the 2DW233 in series with a germanium diode. I also used a random opamp I had but had not the correct pinout (it's a dual opamp). The result is a bit dodgy as I said, but it worked: 5.87v
now I need to find a replacement for this 5.9v reference voltage. Maybe it's time to start playing with these 2DW233 I have...
But it was still not working. After fighting with the poor quality (but available) schematics from the service manual still available on Keysight web page, I could identify the culprit: one of the optocouplers was dead (on the LED side). Funny enough, it is listed as a TIL111, but it's a 8-DIP package (the til111 is a 6-DIP). So I had to improvise...
The unit did power up, but the displayed voltage was all over the place, and a couple of keys had no spring left, so I started there with my plastice made replacement spring trick

Pfff 🤯 j'ai résolu mon premier Rubick's Cube, tu sais, le truc qui traîne sur la table du salon, où tu arrives à peu près à faire une face depuis quelques années...
C'est peut-être d'un banal à pleurer, mais le sentiment que ça donne est chouette.

Thrilled that our paper (w A. Pietri & T. Allançon) «The Software Heritage Filesystem (SwhFS): Integrating Source Code Archival with Development» has been accepted to #ICSE with great reviews. It presents a #FUSE layer on top of #SoftwareHeritage. Preprint in the working! #ICSE2021

Gave an updated #Guix-#Jupyter talk this morning at the UST4HPC workshop, before an audience of sysadmins.
That was a good opportunity to raise the issue of how hosted notebooks deprive scientists from their autonomy and undermine #reproducibility. "There is no cloud".
La discussion a mené au dépot de dossiers de financement et à un site : https://fedeproxy.eu/ et son forum : https://forum.fedeproxy.eu/
