Just landed on official ports tree.
Main branch only, as no CVE listed in Release Highlights.https://cgit.freebsd.org/ports/commit/?id=c58d25dab79e2e2821939713c85a0d992da633e4

fu un progetto chiamato ficep
altri stati usavano saml
il problema non era tecnico ma giuridico: alcuni volevano solo livello assurance high e non accettavano substantial.
per questo nel 2017 proposi a servida e sagstetter di passare ad una modalità uniforme in europa ispirata a SSI, anche perchè alcuni stati non cedevano sul fatto di avere gestori unici autovigilantisi ed io lo giudicavo un problema democratico inaccettabile

può essere, non ricordo di preciso. ricordo che un draft di spid ci fu da inizio 2014. ricordo bene che lo discutemmo in una riunione a palazzo vidoni (da qualche parte ho ancora le slide..)

@andreabont non so se l'economia gli interessi di più della sua narrazione

@mora tutto vero, ma ha anche un senso della storia diverso dal nostro.
cmq. ho messo tutto in condizionale, come vedi...

Issa Rae has canceled her sold out performance at the Kennedy Center. Pulitzer Prize winner Rhiannon Giddens, Peter Wolf, Low Cut Connie, and the Gay Men’s Chorus of Washington, D.C., have also canceled. Lin-Manuel Miranda has canceled the entire Kennedy Center run of Hamilton.

Retro Semiconductors: The Silicon Controlled Rectifier
Over on YouTube [Lockdown Electronics] reviews an old bit of kit known as the Silicon Controlled Rectifier (SCR). Invented in the 1950s the SCR is a type of thyristor and they were popular back in the 1970s. They are often replaced these days by the TRIAC and the MOSFET but you might still find some old schematics that call for them and you can still buy them.
The SCR is a three terminal electronic switch which latches on. You apply a signal at the gate which allows the other two pins, the anode and cathode, to conduct; and they continue to do so until power is removed. The silicon inside the device is comprised of three semiconductor junctions, as: PNPN. The P on the left is the anode, the N on the right is the cathode, and the P in the right middle is the gate.
In the video [Lockdown Electronics] runs us through how to use them and compares them with a TRIAC. Unfortunately the lighting is a bit off for the demo of the SCR with AC power. To finish the video [Lockdown Electronics] wraps up with a windshield wiper control circuit from back in 1977 which is based around SCR technology. If you’d like to learn more about the SCR technology we have covered the basics.

@kattekrab this is so cool!
