Dear HN,I am excited to share my work which I published on Github recently as an open source project and is now ready for you to review/try out.It is a small, physical device with a keyboard, screen, camera and microcontroller (RP2040).With this device you can read and write text messages of up to 299 characters which are ECC encrypted and then displayed as QR codes. The QR codes can be...

Do you know what caused your tinnitus?

Interesting, thank you. With regard to the refresh rate, I saw a recent eReader recently, the difference with my nine year old eReader is striking indeed.

Honest question, why did you buy 10 kindle devices in 10 years?

I just got the best-selling one from aliexpress.

Also replaced my bluetooth speaker battery like that.

Great way to view what is normally hidden, really makes me appreciate plants.

That is what I did as well.

And you can create a second, small partition/filesystem if you still need to persist some things. I used to have very little data to persist and I would mount/write/unmount every time I write to deal with possible power issues.
My tinnitus (from a single loud party), which I had before noise canceling headphones, gets worse with noise canceling headphones, but only temporarily, like 2 or 3 days.

I found out as well that my headphones plays my own voice back to me so that I dont shout, but was able to turn that off in the settings (Jabra 2), which seems to help.

Exactly, Louis XIV had a great reign and was a politically gifted ruler who kept relative peace for 50 years.
Re:Finish Your Projects on Wednesday June 14, 2023 @04:58AM (#36323257)
Agreed. Better to reflect honestly and stop, take the valuable lessons. I try to have fun working on my projects, and not think about the end result all the time. If you are not motivated by money, that is a lot easier of course.

Agreed. Be forgiving, also towards yourself.
Absolutely, this fight needs to be fought on the cultural/political battlefield. It can never be just a technological arms race or solution, because technology usually favors the rich.

Culture eats strategy for breakfast, and mass culture of movies and video games is really the most effective way to teach the broader audience about these issues. Black mirror did a great job with some episoses, and also handmaid's tale has had a big impact in thinking about women's rights.
