The 1e8 salary no doubt came with conditions that would be hard to meet such as AGI (artificial general intelligence). The researchers have no idea how far Facebook's development has gone, but they know how far OpenAI is. It is probably a case of "The devil you know vs the devil you don't."

Sigh. This can't be good for Linux. Microsoft has been very good at bending standards to make their life easier and the life of competitors harder. We already can't boot Linux on x86 desktops without using a Microsoft delivered authorization shim. Embrace, extend, extinguish.

I guess they learned from the last time when they mistakenly shot down a commercial airliner.

My feed is almost exclusively folks complaining about the state of the world, with half of that something the Trump administration just did. None of it is interesting, informative about something I care about (science and engineering) or anything that will remotely put a smile on my face.

My stream is a cesspool of negative posts. It's not like google+ where it was either friends posting of their adventures or random influencers like yourself posting interesting articles. Bluesky needs to figure out how to de-emphasize all the negativity and get interesting postings promoted.

One of the big problems seems to be cathode micro-cracks. The cathode expands when charged and shrinks when discharged. That eventually causes it to fail. I wonder if they could take a page from Roman concrete and mix in something that facilitates self-healing.

Great article about the trials of doing basic research into new battery formulations. There is so much that needs to go right for a battery to be useful for EV use (energy density, discharge power, charge power, cold charge/discharge rate, cycle lifetime).

You need to try Google's Gemini. It gets activated via the normal Google search window and seems to do a fairly good job of finding relevant web pages and summarizing the findings. Asking a full sentence search question seems to activate it. I'm not sure if it is an LLM or not.

I hated it when Tech Support would hand the tough calls they didn't understand to engineering. The reason they didn't understand was invariably that the caller was totally without a clue. I haven't touched my spf entry in a decade, but it's clear that anything but -all is asking for trouble.

My long time observation is that almost nothing gets fixed until it gets so bad that people can't ignore it any longer. I can't wait to see the reaction from the MAGA folks once the store shelves empty and they realize that their beloved leader is an f-ing idiot.

From what I hear LLM's will have problems with things like math because they essentially do a very elaborate "autocomplete" on a closed set of knowledge. The claim is that for math to fit into their scheme of things they'd have to be able to memorize the answers to all possible math problems.

I'm enjoying Google's AI, Gemini., for answering technical questions. It does a great job of zeroing in on not only a good reference but also tends to have a great excerpt that answers the question without me having to click any of the search results myself.

Europe's cloud customers eyeing exit from US hyperscalers : 'It's amazing how fast the change has been'

Cloud computing customers are now fleeing the US. Is the US going to have any foreign customers after the dust settles?

My first thought upon hearing about K2-18b was "Oh great. First we have our domestic terrorists dismantling the government's checks and balances and now we might be facing a future alien invasion."

Life Beyond Earth and Manipulation of Spacetime In an interview last night, I was asked two scientific questions.

Avi Loeb, everyone's favorite alien life enthusiast has a refreshingly evenhanded take on K2-18b.

CDC struggling to fight raging measles outbreak after deep funding, staff cuts In first 4 months of the year, US measles cases are over double last year’s count.

The antivaxer area in west Texas is suffering from runaway measles infections. According to the article one needs to hit 95% vaccination to achieve herd immunity. Ironically these are the same people that voted for the current administration that cut the CDC funding.

You have a wonderful view. Sorry about the land of tariffs putting a blemish on it. I tried my best to stop the idiocracy but was overruled.

It is simply good resource management. Always have a hot spare.

According to that map it shouldn't be possible to fly west from California to Asia yet we can. Doesn't that give flat earthers a pause for thought? At a minimum the earth needs to be a cylinder aligned with the poles.

The average person simply doesn't think creatively enough to spot the possibilities. Perhaps schools and colleges can help teach people to think more creatively and think "what can I accomplish with these tools?"

The problem as I see it is that the people finding the exploitable software errors are much more creative at finding loopholes in the code than the average software author. Current exploits often chain multiple minor non-exploitable bugs together in order to create an exploitable one.

I'm so relieved to see this. It would have been a total disaster without some central site keeping track of all the vulnerabilities. I fear that the curve shape for finding them over time is an exponential with the curve for software folks learning what to avoid only growing at a lower rate.

Why would a state-sponsored attacker attack from an IP address within their own country? I'd bet it is either not state-sponsored or not from Russia or both.

The CVE program for tracking security flaws is about to lose federal funding CVEs are used by Microsoft, Apple, Intel, and many others.

Common Vulnerabilities and Exposures are the basis of almost all of the security fixes in our software. Without that list many security issues will fall through the cracks and attacker will have a field day. Will Europe or Asia have to become the caretakers of this important list?
