A very interesting take on the universe as seen from the perspective of the 2m amateur radio band by the #LOFAR radio telescope.

V-LoTSS: The Circularly-Polarised LOFAR Two-metre Sky Survey
We present the detection of 68 sources from the most sensitive radio survey in circular polarisation conducted to date.arXiv.org
I was unable to pull the data wire, since the duct was obstructed, so I went the wireless way. Next step: attempting to switch telemetry from legacy to standard format.

j'avais évité ce truc car zéro intégration avec home-assistant et pas envie de bricoler... dommage ça semblais quand meme intéressant. enfin, 50€ pour ça ça reste quand même du vol.

In 1959, the IBM 1401 computer was built from boards called SMS cards. A single board might hold just 3 logic gates so the computer needed thousands of boards.

We have to deromanticize community. It's not some pristine untouched forest of soft moss and good vibes. The corporations count on that misconception to stripmine us for content.
Community has always been as weird and messy as humans are. It's work. It's relationships. It's hard. There isn't a magic number. They aren't inherently anticommercial. They don't all look or act the same.

I slept very poorly last night due to the news that Musk gave privileged / possibly PII & DM level access of Twitter mod access to a variety of strident anti-LGBTQ (especially anti-trans) bigots who masquerade as journalists. This is an incident which would require user notification under California law, if it weren’t for the platform owner granting it. It still might be a violation of privacy laws. It’s absolutely a disaster for all LGBTQ people who used Twitter.

I wonder how famous people cope with this.

In August 2011, Los Alamos techs posed 8 plutonium rods on a work table to take a few photos.
Had these rods rolled into each other there would have been an instant criticality event. (Think "Demon Core")
Worst still, a supervisor who saw the display ordered the techs to safe the rods, ignoring the protocol to evacuate EVERYBODY (b/c even a hand could moderate the neutrons & cause criticality).
It caused a 4-year, billion-dollar shutdown.

Transgender day of remembrance
For #TDoR2022, I'm having a thought for @lumi_enby@twitter.com who left us on Dec 31st, as well as all of us who didn't make it because of transphobia. We miss you.🕯️

Finally got rid of Google Authenticator (I'm using Aegis as a replacement). The transfer was a bit tedious, because you need to export up to 4~6 accounts each time with the QR code technique but it worked.

This a small python script you can use to post from the command line.
Go to Preferences>Development and create a new application. Then grab the access token and put it in the script along with your instance name.
###
import requests as r
import sys
h="https://YOURINSTANCE"
t="YOURTOKEN"
a=sys.stdin.buffer.read().decode("utf-8")
d={"status":f"{a}"}
u=f"{h}/api/v1/statuses"
p=r.post(u,data=d,headers={'Authorization':f'Bearer {t}'})
###
Then just printf or echo your post and pipe into it

a couple of years ago I wrote a (partially complete) "Modbus Tweets" account on the bird site. Never finished it. Kinda wanna dust it off for Mastodon though. I was going to have one of my home's lights operable via @ and DM, just base64 encode a modbus request and get a base64-encoded response...
in reply to K. Reid Wightman :verified: 🌻
@reverseics that's such a sick idea. The twitter dev API is annoying because you need to apply to do an application and can get rejected (like me) for not having a good enough reason to have a token. There's a lot of potential for really easy automation with mastodon and enough access controls to make it work without as much hassle

7th month. Interaction between Fexofenadin and Spiro is confirmed, as far as I'm concerned. Since I've stopped the former on last month, the latter's effects have been reduced, which can be seen by the reduced K levels in blood. Let's see what gives with blood pressure tomorrow.
T: 0.96 nmol/L (-0.14), E2: 382 pmol/L (+11), LH: 0.3 U/L (-0.18), FSH: <0.11 U/L (same as last mo.)

Same settings as last time (13J/cm², 3ms pulses, 755nm), but with a wider diameter. Jaw line is still the most sensitive part, but the improvement is undeniable. 💜✨

I keep seeing people say Mastodon is nothing like Twitter. And they’re right.
Mastodon is an echo of the old internet, it’s decentralised, chaotic. What you get depends on your sysadmin. You can’t search, everything has to be shared to you by a human. Networks split apart and rejoin. What you see is your unique connection to it.
Is this good? Maybe. But for me that’s the internet I grew up with. No algorithms, no targeted adverts, just human interaction, and it was glorious.

This also is very much like early Twitter. I joined in 2007. Twitter was a cheap group SMS service, it connected you to your friends not to companies and celebrities.
I get that I’m not like most people. I grew up in a very conservative rural area so the internet has always been my connection to friends and peer groups, a way to converse with people rather than a way to escape or get famous.

@Jelora, est-ce que serveur minitel est encore opérationnel? Je viens d'apprendre que Xtel est encore packagé sur Debian, et si c'est encore le cas, je vais sortir mon Sportster Flash pour tester ça :3

Find your Twitter friends on Mastodon!
Pour l'instant c'est surtout s'assurer d'être facilement trouvable grâce à cet outil, car peu de monde (en tout cas dans la twittosphère fr) y à déjà associé ses deux comptes. Mais plus l'usage se répand dans nos communautés, plus ça sera utile :).

Testing Mathjax on my instance with the Maxwell-Faraday equation:
$$\oint_{\partial \Sigma} \mathbf{E} \cdot \mathrm{d}\boldsymbol{\ell} = - \frac{\mathrm{d}}{\mathrm{d}t} \iint_{\Sigma} \mathbf{B} \cdot \mathrm{d}\mathbf{S}$$
$$\oint_{\partial \Sigma} \mathbf{E} \cdot \mathrm{d}\boldsymbol{\ell} = - \frac{\mathrm{d}}{\mathrm{d}t} \iint_{\Sigma} \mathbf{B} \cdot \mathrm{d}\mathbf{S}$$
TIFO friendica supplies a Mastodon-compatible API since 2021.06, meaning that I can use Tusky with my instance 💜

tu dois pouvoir utiliser le crossposter alors je pense si une appli mobile arrive a l'utiliser
Hi all, this account is still active, I'm planning to use it in case #deletetwitter takes form. TBH, I need to check if I can use something to cross-post to the blue bird from here, it would be a good solution.
