hawtkeyon Fusion energy breakthrough by Livermore Lab

here's a video that shows a machine at Berkeley lab that makes a high-performance magnet wire, not sure if it's related to this project but still pretty interesting to see how complex just the wire is- https://www.youtube.com/watch?v=FmmNRaKpBTI&t=2138s

hawtkeyon We need more water than rain can provide: refilling rivers with desalination

Beaver dams are a good example of this too. Beavers were building bioswales everywhere in North America for free and we killed almost all of them and wore them for hats.

hawtkeyon Lego Spectrometer (2017)

This guy Les put together a piece of software to view/calibrate a spectrum[0]. He also has a YT channel[1] where he builds a couple RasPi spectrometers using pre-made spectroscopes that run $50-100, but the whole package is a lot more compact.

There are also a number of spectroscope enclosures on thingiverse, but it's always so hard to gauge if any of the projects are actually worth printing. The most dead-simple and cheap example I found used the same slit/CD plastic combo capped onto the ends of a paper towel tube.

Some other stuff[2,3,4]

hawtkeyon DuckDuckGo Traffic

how about a blacklist browser extension, and like pi-hole, simply share lists of bad domains to omit from search returns.

hawtkeyon Ask HN: Why is today's Internet experience so user hostile?

I was able to take a screenshot of GAuth backups on iPhone using the button hotkeys(IE: Power+Volume up). I setup a container that runs a go version of GAuth and used a python script to decrypt the (decrypted QR code) backup keys. Then I backed up the encrypted keyfile to offline disk, encrypted the container backup and deleted it from the hypervisor.

hawtkeyon Unhook: Hide YouTube Recommendations

I really like the new containers feature in firefox for this- I have a trash container so my main youtube container doesn't get polluted.

hawtkeyon Windows Subsystem for Linux GUI

I think the main target is ML applications that depend on GPU access and being able to run a WM is just a side-benefit.

hawtkeyon Experiments on a $50 DIY air purifier (2020)

I've found that tacking 'pdf' onto search queries gets through some of the SEO garbage. For instance I did 'home dust filtration pdf' and found this pdf:

https://www.epa.gov/sites/default/files/2018-07/documents/re...

which cites this paper about deposition rates of different particle sizes:
