  • I don’t know about this specific case, but it’s common for the big name researchers not to do any actual research or play any direct part in generating their images. That’s often done by kids - 25 year old grad students, even 20 year old undergrads - or other trainees. Those people may not appreciate how easy it is to detect image manipulation and are still learning what kinds of ‘refining’ of imagery and datasets is acceptable, while the PI that pays their stipend or sponsors their visa rages at their inability to get an expected outcome or replicate a previous result.

    Not saying there aren’t people out there just flat-out frauding, but these are group projects with a structure of trust and pressure that can muddy assignment of culpability. Like any committee or corporate action, it can be tough to say that any one individual is the guilty party or which people where just going along with the group.



  • University is ok if you’re starting at zero and don’t even know what’s out there. It’s for exposing students to a a breadth of topics and some rationale of why things are as they are, but not necessarily for plugging them into a production environment.

    Nothing beats having your own real world project, either for motivation or exposure to cutting edge methods. Universities have tried to replicate that with things like ‘problem based learning,’ and they probably hope that students will be inspired by one or two of the classes to start their own out-of-class project, but school and work are fundamentally different ways of learning with fundamentally different goals.






  • The relevant text of the law is

    The products must be available to all menstruating students in restrooms regularly used by students in grades 4 to 12 according to a plan developed by the school district.

    so, I think “boys bathroom” only in the case where a school has trans-boy without puberty blockers or hormone therapy. Clearly a very edge case, but right-wing propaganda depends on blowing up rare events or special circumstances, pretending they’re happening everywhere, all the time, and therefore an immediate threat to the way their audience has always done things.









  • I came to MySQL and Apache because they were the backend for other services I wanted to start,. Later, when I wanted to build my own, I already had Apache running, so why would I add nginx? I did let other services add sqlite, but have (in most cases) figured out how to switch those to MySQL.

    All of that has been running for 20 years. I’m sure it would be good for my dementia-risk to learn how to start ngnix and migrate all those services, but it’s far more attractive not to mess with what works.


  • The CO2 sensor calibration thing is inherent in the technology. They drift, a lot, and without occasional reference to a known standard, there’s no way to know whether “1000” is really 1000, or 500, or 2000, but exactly how that gets implemented seems to vary a lot. I have an SCD30 board from Adafruit, which internally records CO2 minima and, over the course of week or so, adjusts its calibration so that minimum is 420. That means no special calibration procedure, but it does have to be somewhere that it gets periodic fresh air exposure.

    There’s a newer, photoacoustic sensor technology that doesn’t seem to require continuous recalibration, but (at least this one: https://www.sparkfun.com/products/22956 ) require an extensive initial calibration.


  • My CO2 sensor has dramatically changed my routines. My space isn’t small - maybe 1200 square feet/100 sq m - but it must be pretty well sealed, because I can easily see my own breathing add to CO2. Nevermind cooking on the gas stove. Treadmill time adds 500+ ppm.

    Now, I open windows every chance I get (which isn’t super often, because the dewpoint is 70 oF/20 oC in Atlanta), and I’ve shifted a lot of my cooking to an electric tea kettle, hot plate, and toaster oven.
