This is wild... Russia seems to be threatening a *commercial* satellite that provides imaging services to Ukraine:

▸ starting about two weeks ago, Russia started maneuvering five (!) of their classified satellites to the same orbital inclination as the ICEYE satellite

▸ these burns were big, on the order of 100 m/s, clearly using chemical propulsion given the speed of the burns — very expensive and deliberate maneuvers

▸ as of last Friday, all five Russian satellites are now co-planar, at ~97.8° inclination, with three of ICEYE's satellites, and aligned in other orbital elements (e.g. RAAN) that make it clear they're specifically targeting this set

▸ I am a little skeptical that Russia is specifically targeting -X36 — there are two other satellites at the same inclination/RAAN (-X37 and -X38) — but the Russian sats are now all within striking distance of -X36, which is why people are concerned about it specifically; the closest cross-track distance is an estimated 500 meters (!!), all while the satellites are orbit 550 kilometers above Earth

▸ Russia has unleashed a cyberattack on a commercial satellite before (Viasat), and it is official Russian policy that commercially-owned infrastructure that aids in military efforts "may be legitimate target[s] for a retaliatory strike.”

▸ there's speculation that this could be a precursor to an RPO mission (meaning: physically grabbing the satellite or some other kind of non-kinetic attack like blinding/jamming)

Worth tracking closely. And unfortunately more evidence that space is militarizing, fast.

If you want to age your sys admins 30 years overnight, remember that Active Directory is fully unicode compatible, so you can rename your laptop with emojis it its hostname, and it will reflect like that in AD

We implemented @karpathy 's MicroGPT fully on FPGA fabric.

No GPU.
No PyTorch.
No CPU inference loop.

Just a transformer burned into hardware, generating 50,000+ tokens/sec.

The model is small, but the idea is not: inference does not have to live only in software 👇

Does anyone know what happened to #ForensicsWiki ? If they need hosting, we would gladly help, or at the very least, mirror their mediawiki installation for safekeeping.

Welcome to 2019, traveler from 2009. The brief:
-sysadmins are now "ops"
-servers are all just "cloud" something
-algorithms are "AI"
-DBs are "blockchains"
-Everything that spies on people is "smart"
Good luck. And update your CV with the above words.
