Submission + - Tesla lays off 'more than 10%' of its global workforce (electrek.co)

Submission + - Popular xz compression utility compromised (yahoo.com)

EmagGeek writes: "German software developer Andres Freund was running some detailed performance tests last month when he noticed odd behavior in a little known program. What he found when he investigated has sent shudders across the software world and drawn attention from tech executives and government officials.

Freund, who works for Microsoft out of San Francisco, discovered that the latest version of the open source software program XZ Utils had been deliberately sabotaged by one of its developers, a move that could have carved out a secret door to millions of servers across the internet."

Comment Re:kWh/day considered nonsense (Score 2) 68

False. Large datacenters and distributed virtualization platforms modulate cycle availability to maintain relatively constant power consumption. Lower priority tasks are often paused, or given higher priority, depending upon the overall power load.

There is a lot of science thrown at load modulation because of the way power is billed. For commercial and industrial customers, electricity is billed based on both average and peak demand, and the latter is tremendously more expensive than the former, so it is important to keep peak demand low.

Incidentally, this is why EV charging networks will all fail eventually, because they will never turn a profit. I'll give you one example: an EV charger on Dominion Energy in Virginia... a single 75kWh charging session at 150kW will cost the EV charging company approximately $26,800 in peak demand for that billing cycle, and generate approximately $35 in top-line revenue.

So, you can bet your ass that datacenters are going to deploy whatever means are necessary to manage their peak demand, including priority modulation.

Comment Re:Good PoE Camera? (Score 5, Informative) 174

I have a bunch of Amcrest cameras. They're all PoE and have worked pretty well for me. They can push to Amcrest's proprietary cloud, but they can also push to an NFS server or any other security software suite that supports rtsp. They have a published API that anyone can use without a fee to access their camera's streams.

I've been totally happy with them.
