‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects

Every spring there are fewer bugs in our garden, and walking around we see signs on half our neighbors lawns warning about pesticide application. It's ridiculous that on top of the agricultural pesticide use, we even allow residential use... FOR GRASS.

The pollinator garden is coming along nicely though in our yard, and it is one of the busier ones in our area which is nice.

I replaced Windows with Linux and everything’s going great

I dual booted fedora kde 2 months ago with an AMD GPU and it has worked just as well as windows 11. There were some initial setup options I had to enable for proprietary drivers, but aside from that it has been solid. A few glitches here and there, but about the same as windows 11. I also went into this committing to not use the terminal, and so far I have been successful.

How to power a 4-pin CPU fan?

1st, do not power the fan from the pi if possible to avoid any underpower headaches. It should be fine.

Your best bet is to just power it at 5v using a standard USB wall wart and a sacrificial USB cable (old 2.0 ones work best). Strip the USB cable and expose the positive and negative wires and hook them up to the positive and negative fan pins (identify these using a 4pin fan header diagram). You can either try just shoving the tips of the USB cable into the fan header using electrical tape as a quick bodge, or cut and strip the fan cables and twist them together.

Destroyed my Glass Print Bed - What to do now

Reply in thread

You just stick the magnetic backing to the existing glass plate for flatness and rigidity. You might have to bump the heated temp 1 or 2 degrees to compensate for the additional thickness, and you may lose a couple of mm/s of print speed at the high end due to the additional weight. That said, it is a very cheap and easy to execute option.

Safe to run a box fan face down?

Box fan bearings are not typically designed to run in that orientation. It will probably run for a while before failing prematurely. Might make it a couple months or just a few weeks.

This is a much more robust fan and they come in various sizes to better fit your opening. They move a lot more air, and many styles come with a thermostat and speed controller. Sorry for the Amazon link, this is just the general style: https://a.co/d/bLeBCeD

How to power NAS HDDs externally?

To answer your question, yes that PSU looks like it should work. I'm not sure I would use this PSU for my NAS due to the quality of the manufacturer being unknown, but generally it should be fine so long as it is not mission critical.

Also if you have access to a 3d printer, there are some great designs for external drive cages to keep them safe and cool.
