Some exciting news to share: very soon, NOAA Research will be hiring new federal employees into science positions across the agency! A couple of notes: 1) They will only be open on USAJobs for seven days. 2) Multiple positions at different sites may be in one posting. (1/2)

So loads of people are sharing an obvious ai "glow up" of an actual photo. I never share ai stuff even to dunk, but in this case I'm sharing a comparison to show the problem. We have to stand against this slop at every level or it becomes normalised. They want us to stop caring. See alt text.

Data centers can play nice with the grid if they come with battery storage. Tesla has done a good job highlighting this in their Megapack materials. What will it take for this to be more widely known?

Yes, the city needs to actually repave streets. Yes, the city needs to repair sidewalks. Yes, the city needs to install curb ramps. But the bigger problem is that when LA decides to do anything at all to "help" pedestrians, the result looks like this complete and utter bullshit

Improvements in public health have been the source of most of the reduction in morbidity and mortality. It seems a lesson that mostly falls on deaf ears in the US where most of the investments flow to research on genetics and gene therapy.
