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.

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?

"any further tariffs from the US side would 'no longer make economic sense,' and that the US 'will become a joke in the history of the world economy.'" The tariffs of over 100% are already so high that it is unlikely that consumers in either country will be buying the other country's products.

Turkeys down the street from me. It must be mating season. The two males seem to be trying really hard to get the 3 female's attention.

Trump claimed the Biden administration spent $8 million "making mice transgender." The White House tried to back up this number with records of funding for research into cancer, asthma, and HIV, some of which used *transgenic* (genetically modified) mice.

The backlash has started. Tesla sales appear to be suffering as well as providing a nucleation site for protests. I see a parallel to when Steven Jobs was forced out of Apple and some soda exec took over. Things didn't go well till Jobs returned. Will Tesla be similar by firing Musk?

I'm having fun playing with a locally-running instance of Deepseek-R1 running on my Fedora laptop. Wow, it probably won't pass a real Turing test but it is hard to remind oneself it isn't human. It certainly fakes it really well. I would post the transcript but cutting it up into 10+ posts is t

Ok, quick thread on why DeepSeek is blowing up assumptions about LLMs and maybe the whole (U.S.) AI industry. DeepSeek is an AI lab funded by a Chinese hedge fund, their AI code is open source, meaning freely available to use, which most big U.S. models (aside from Meta’s) are not. That’s the start…

Everyone should upgrade their web login security and start using passkeys. Passkeys are real public key security where the remote site can't reveal your secret key because the secret key never leaves your computer (or phone). It also can't be phished since the user can't see it either.

This is a good example of why government mandated back doors such as CALEA are a terrible idea. End-to-end encryption (such as the Signal chat program) is the only way to be certain that a compromise at a third party site can't jeopardize the communication's security. #Signal
