Submission + - Google tests AI processor in space (npr.org)

Geoffrey.landis writes: Google just put a satellite testing AI chips into space. The refrigerator-sized satellite is part of a research project, "Suncatcher," the company hopes can pave the way for orbiting AI data centers powered by the sun. The prototype satellite has four specialty chips in it called Tensor Processing Units, or TPUs, that Google designed for machine learning and has already deployed in data centers on Earth. The chips will run a version of the company's Gemma AI model for 15 minutes at a time due to heat management constraints, using the open weight model to answer simple queries. In a blog post, Google said the mission will gauge how the TPUs handle "the physical stress of spaceflight and the radiation and thermal extremes of space." The satellite launched October 1 is a prototype that Travis Beals, senior director and lead of Project Suncatcher, called "a very minimal test" to make sure the chips can run in space. A SpaceX rocket carried it into orbit, and Planet will get it up and running. Beal said Google will then fire up and test the TPUs. The goal is for the mission to be operational for a year.

Those dudes probably don't know how to make the difference between file cache and memory usage. All computers including those using Linux will use ALL their memory for file caching e.g. caching the content of files into memory.

Here is an example:
free -h
                                                        total used free shared buff/cache available
Mem: 7.8Gi 617Mi 586Mi 53Mi 6.6Gi 6.8Gi
Swap: 15Gi 66Mi 15Gi

This computer has 8GB of memory, ~586MB of free memory, and ~6.8GB of available memory because it uses the spare ~6.6 GB for file caching, all OSes do that. That memory used for file caching is available instantly for the OS at anytime and must be excluded from the memory the OS uses. All spare memory will eventually go to file caching. Again all OSes work like that.

So 8GB ram 586MB free and 617MB used by the OS and running programs so 6.8GB available

So you need to be able to tell the difference between free memory (you shouldn't have any or very little if your OS works correctly) and *available* memory. That memory used for file caching is avaiable on demand at any time for the OS and running programs

Also don't look at "virtual memory" used you need to look at "resident memory"

Example:
On the same host as above:
1004 mysql 20 0 1759176 355056 7560 S 0.0 4.4 61:13.76 mysqld

mysqld uses 1.7 GB of virtual memory but only 355MB of resident memory. That 1.7GB of virtual memory doesn't really matter. All OSes including Windows work the same way although they often name thing differently. You need to know how to interpret what you see...

There is a reason why its not enforced, it is exceptionally hard to prove AND generally doesn't rise to criminal activity. Politicians lie all the time in Advertisements. All sides do it. It isn't new, or one side is better than the other.

A politician can say they are in favor of the new "don't kill puppies and kittens" law, that also has a bit that allows them to send millions to their buddies at the "don't kill puppies and kitten NGO" and doesn't save a single puppy or kitten. And if you oppose it, you hate puppies and kittens and want to kill them. Its all a lie, wrapped up in emotional language. What can I do to stop it? Who do I call? And why do they hate puppies and kittens?

So, this Meme Coin Law isn't going to do anything useful except for "Owning " someone somewhere for political points. Puppies and Kittens.

You can shout "Fire" in a theater. There is no such prohibition anywhere. Especially if there is a fire. What you can't do, which doesn't fall into 1st Amendment arena, is causing panic without cause. That has VERY specific legal criteria that must be met. "Narrowly tailored".

And people can lie in advertising, and do all the time. There are a whole bunch of hoops that one must jump through to bring such a charge against the advertiser, specifically to protect 1st Amendment rights. There are, indeed very NARROW and TAILORED precedents that are designed to PROTECT 1st Amendment rights.

You're the kind of person the 1st Amendment Auditors love to target. They are annoying, but also operating legally, as much as that upsets people.

Crying "Bullshit" does not make your case, it literally says exactly what's going on, you are emotionally responding to things you don't like.

You can claim all the stuff you want to claim, and that doesn't make it right simply because you cried "BULLSHIT".

And yes, a business plan is a first amendment right. If it is a pyramid scheme, then go after that, it is already illegal. Meme coins are just modern Digital BeanieBabies. I know plenty of people who spent enormous amounts on those (and similar pop culture items), and then are left holding mostly worthless trinkets.

Sorry, but just because some Karen (Newsom here) says "There ought to be a law" doesn't mean there should be a law.
