Flamenco can be a very challenging and technical style, but it doesn't have to be. I don't know your background, but if you just want to have fun and sound good quickly, try this. Get a nylon string guitar. It doesn't have to

What I like about nostr is the experimentation with different clients, and the fact that your identity is portable to any of them. It's just a really cool model. I'm working on a nostr-based discussion site heavily inspired by HN&

While I agree that sheet notation is superior, it actually is fairly common to indicate duration and articulation in tablature, especially classical. See many of the tabs on classtab.org: https://www.classtab.org/tabbing.h

Great article! I have some miscellaneous comments, in no particular order. The digital commitment scheme as described has a subtle vulnerability. Suppose there are two participants, A and B. B decides to wait until A's hash is shared.

I linked to the paper because it wasn't clear if OP's goal was to increase the security with the cascaded hashes or not, and also because I personally found this result very surprising and interesting when I first learned about

Thanks! Does this attack actually depend on extremely large files in any way? My understanding is that this method can always find fixed-size pre-images for collision attacks, and is unaffected by the pre-image size in a pre-image attack. T

This is not necessarily as secure as you might expect. See Joux's "Multicollisions in Iterated Hash Functions. Application to Cascaded Constructions" https://link.springer.com/content/pdf/10.1007&#x2

The Inkplate platform is really neat. Sorry to see they shipped yours without the MCP23017. I used one of those pins for my project: https://hoytech.com/tabplate/ But probably some of the GPIO pins on the ESP32 are usa

I had Dr. Alan Paeth as a university professor for 4 years, one or two classes every semester. I tried to fit my schedule around the classes he was teaching. When you went to his classes you really had no idea what it was going to be about.

I agree, labelled loops are fantastic. I don't know for sure, but I believe the JavaScript feature was inspired by Perl, which has had them since at least the v4 releases (1989-1993): https://www.rexswain.com/perl4.html

I experimented with ObjectBox a bit, but I decided against using it because it isn't open source. The language wrappers are apache2 but the core library is only provided as a binary blob. I think this is bad because you can't insp

Not sure how standard it is, but at least on linux you can do "head -3" as a short-cut for "head -n 3". Same with tail.

Yes, exactly, otherwise buggy applications wouldn't be a big deal because we could run them on their own dedicated computers. Section 2.5 of this paper has a good discussion on this: https://cr.yp.to/qmail/qmailsec
