🔴🇮🇹 À travers toute l’Italie, le peuple a répondu à l’appel à la grève générale en solidarité avec la Palestine convoqué par les syndicats de base. Partout, des cortèges remplis d’étudiants et de travailleurs ont défilé en faveur de la reconnaissance de la Palestine.
Des centaines de milliers de personnes se sont organisées pour bloquer et paralyser les transports, l’éducation et les services publics afin de forcer le gouvernement d’extrême droite de Meloni à reconnaître la Palestine. Ils ont annoncé qu’ils continueraient à « tout bloquer » tant que le gouvernement ne plie pas. Le pouvoir du peuple en action.

@jackyan I have to admit, I don't know all the names, and they were marketed under different names in North America. The model info on my vehicle id plaque is D21FH, where I guess the F stands for "Familiale". Anyway, it's a station wagon or estate car, or "break" in French.

How A Failed Video Format Spawned A New Kind of Microscope
The video cassette tape was really the first successful home video format; discs just couldn’t compete back in the early days. That’s not to say nobody tried, however, with RCA’s VideoDisc a valiant effort that ultimately fell flat on its face. However, the forgotten format did have one benefit, in that it led to the development of an entirely new kind of microscope, as explained by IEEE Spectrum.
The full story is well worth the read; the short version is that it all comes down to capacitance. RCA’s VideoDisc format was unique in that it didn’t use reflective surfaces or magnetic states to represent data. Instead, the data was effectively stored as capacitance changes. As a conductive stylus rode through an undulating groove in a carbon-impregnated PVC disc, the capacitance between the stylus and the disc changed. This capacitance was effectively placed into a resonant circuit, where it would alter the frequency over time, delivering an FM signal that could be decoded into video and audio by the VideoDisc player.
The VideoDisc had a capacitance sensor that could detect such fine changes in capacitance, that it led to the development of the Scanning Capacitance Microscope (SCM). The same techniques used to read and inspect VideoDiscs for quality control could be put to good use in the field of semiconductors. The sensors were able to be used to detect tiny changes in capacitance from dopants in a semiconductor sample, and the SCM soon became an important tool in the industry.
It’s perhaps a more inspiring discovery than when cheeky troublemakers figured out you could use BluRay diodes to pop balloons. Still fun, though. An advertisement for the RCA VideoDisc is your video after the break.

See, this is what I hate about Dallas. People are opposed to HEB, one of the best things about Texas, opening a store here, and I just can't with these people.

Abbattere il patriarcato, frantumare i generi, liberare i corpi. Anarchia e transfemminismo
