After Decades, Linux Finally Gains Stable GPIB Support
Recently, [Greg Kroah-Hartman] proclaimed the joyous news on the Linux Kernel Mailing List that stable General Purpose Interface Bus (GPIB) support has finally been merged into the 6.19 Linux kernel.
The GPIB is a short-range 8-bit, multi-master interface bus that was standardized as IEEE 488. It first saw use on HP laboratory equipment in the 1970s, but was soon after also used by microcomputers like the Commodore PET, Commodore 64 and others. Although not high-speed with just 8 MB/s, nor with galvanic isolation requirements, it’s an uncomplicated bus design that can be implemented without much of a blip on the BOM costs.
The IEEE 488 standard consists of multiple elements, with 488.1 defining the physical interface and 488.2 the electrical protocol. Over the decades a communication protocol was also developed, in the form of SCPI and its standardized way of communicating with a wide range of devices using a simple human-readable protocol.
Although the physical side of IEEE 488 has changed over the years, with Ethernet becoming a major alternative to the short GPIB cables and large connectors, the electrical protocol and SCPI alike are still very much relevant today. This latest addition to the Linux kernel should make it much easier to use both old and new equipment equipped with this bus.

@RFancio According to Grandi, Artusi collected recipes from rich Italian families, which were often imported from abroad.. but the everyday cuisine was very different. I don't think this is enough evidence to call those recipes "traditions". But anyway, I am not an historian 🙂

@steek_hutzee quale guerra? È un operazione militare speciale! E comunque grazie, oltre ai miei genitori, ai partigiani che, invece di arrendersi all'esercito della Repubblica di Salò, salirono sulle montagne

@francina1909 nonostante pioggia e ventazza, io sto ancora bene, ma io ho sempre caldo...

@fucinafibonacci Finirà comunque che quei territori resteranno alla Russia (se si vuol davvero far finire la guerra).
Mi spiace per chi crede(va) nel riarmo senza fine dell'Ucraina come unico metodo di resistenza (o di vittoria, come lo definì la Meloni), ma al momento non vedo altra soluzione considerato poi che la stragrande maggioranza di chi vive in quelle terre non si è mai considerato ucraino ed in vista di un eventuale referendum voterebbe in massa per l'annessione alla Russia.

@aethernaut «entire deck short of a deck» is my new favorite expression. Also loving this guy, whereby «loving» I mean «hope Simane managed to throw HIM in». Which is going to be with t much more than 50 headless clones, incidentally, I'd wager.
