University of Kentucky shifting to online classes for two weeks amid coronavirus worry

Posted on 2020-03-11 by pappp

Source: Kentucky.com -- Education

Article note: Here we go! Time to find out if I can run our Verilog-based EE282 labs remotely. I think we can roll with online Verilog toolchains (I hate EDAPlayground, but it'll do... or maybe Hank's Icarus-backed webform..), canvas submit prelab, canvas submit code, and online help sessions via Canvas and/or Zoom.

The University of Kentucky will transition to online instruction for two weeks after its scheduled spring break next week in an effort to curb the spread of novel coronavirus, officials … Click to Continue »

Intel is changing the future of power supplies with its ATX12VO spec

Posted on 2020-03-09 by pappp

Source: Hacker News

Article note: I like it, it's basically removing redundant vregs and wiring the way machines are composed now. Will be a shame to lose the +5, but everywhere you use it might as well have an inexpensive separated vreg. The connector (10 pins, [PS_ON,Com,Com,Com,Reserved,Pwr_OK,+12SB,+12,+12,+12 sense] looks appropriate, though it looks in the spec like there is no marker (green stripe?) on the +12sense line to distinguish it from the ones that are supposed to carry current.

Computer systems at UK and UK HealthCare hobbled by massive, month-long cyber attack

Posted on 2020-03-08 by pappp

Source: Kentucky.com -- State

Article note: HL article has _considerably_ more detail than UK's PR pap. UK clearly got hit by cryptocurrency mining malware like a month ago, thinks they finally kicked it this morning, and it sounds like it probably infected the big probably-licensed-from-SAP administrative systems. ...now if only we could get a trim for some of the administrative bloat those systems are selected by and entirely for the benefit of.

The University of Kentucky and UK HealthCare conducted a major reboot of their computer systems early Sunday morning in an effort to end a month-long cyber attack that university officials … Click to Continue »

New AMD side channel attacks discovered, impacts Zen architecture

Posted on 2020-03-07 by pappp

Source: Hacker News

Article note: Ooh. AMD's turn. Every AMD design since Bulldozer (2011) has a metadata-leaking behavior in their L1 data cache. PoC from Javascript in a browser (bad) but it appears to only leak metadata so it's slower and harder to extract useful information than the previous high-profile Meltdown/Specter type bugs (good). Also interesting, it sounds like the research was at least partially funded by Intel, which is probably "we were looking for bugs in x86 parts and Intel sponsored us because they're bounty-ing their vast side-channel problem to get ahead of it" but may be borderline industrial espionage to take the heat off.

Intel x86 Root of Trust: Loss of Trust

Posted on 2020-03-05 by pappp

Source: Hacker News

Article note: Womp-Womp. Intel's "Privileged black-box computer inside the computer" security by obscurity model may be subvertable by ... making a DMA write into said privileged black box's memory before it wakes up enough to disable them. Hopefully this will be helpful in hacking fully-Open stacks onto Intel boxes going forward, and/or subverting the TPM-based DRM schemes.

Article note: The death of Reader, and by extension the depreciation of RSS/open protocols/self curation/platform ownership for all but the most technically sophisticated has been bad for Google, and worse for society at large.

Judges rule that YouTube isn’t bound by the First Amendment

Article note: On one hand, duh, it's a private venue. On the other hand, we really need to reckon with this situation where all our substitutes for a public sphere are privatized.
A federal appeals court has upheld the dismissal of a lawsuit against Google by PragerU. By coming to that decision, the judges backed the previous court's ruling that internet platforms aren't subject to the free speech requirements of the First Ame...
