You might like to try kefir grains. They are very stable, I've had the same grains for 5+ years, and you can leave in the fridge for months if you like. I used to use dedicated yogurt culture, but "kefir yogurt" tastes exactl

If it helps, the T-Beam (first link in hardware section) has meshtastic pre-installed. But yes, it's still sort of a kit since you need to solder the 4 pins for the display and bring your own 18650 battery (and 3D print a case if you l

I've always wanted to try this, so I built this kit a while ago: https://www.eio.com/products/velleman-k8118-stereo-ultrasoni... It actually turned out even cooler than I expected. A lot of things emit ultrasound

I really like PDL, even though I don't get to use it much anymore. Here's a fun application, FM radio demodulation in a page or so of pretty straightforward code: https://hoytech.com/talks/fm-demodulation

Fascinating! It's sort of similar to "bootlegged" guitar tabs on alt.guitar.tab newsgroup and OLGA. There was lots of legal action by publishers and a lot of the content is now lost, or at least not easily accessible online a

Thank you for sharing, and please accept my condolences. About memorialising IRC nicks, I understand why this is done but maybe it doesn't need to be a perpetual reservation? When an amateur radio operator passes, their callsign become

Congrats! The condition system isn't very well described elsewhere, especially relative to how cool it is. I just ordered your book, looking forward to reading it.

Thanks! Yes I believe the SMT implementation as described in the Certificate Transparency paper always does the full 256 hashes per insertion. That seemed unreasonably high to me too, which is why Quadrable uses a "collapsed leaf"

I didn't know that, thanks! It looks like these ideas were being tried in perl and python roughly in parallel.

I was referring to wrapping typed arrays in "normal" scripting languages, allowing integration with a larger eco-system, which is I believe why NumPy is more commonly used today than APL.

by hoytech 6y ago
Let's not forget to give at least some credit to Perl Data Langauge (PDL). It pioneered a lot of these ideas 10 years before NumPy existed, and is still a pretty great tool today: http://pdl.perl.org/index.php?page=Firs

Well, FORTIFY_SOURCE >= 2 will reject "%n" unless it's stored in read-only memory. And Ubuntu at least makes this a gcc default, so I wouldn't say nobody is doing anything against it: $ cat tp.c #include

I'm told that in the 70s, when backgammon players had a dispute about the correctness of a move (usually a double), they would agree to continually setup the board from that position and play game after game, until somebody capitulates

The problem here is connecting a program you want to run to completion to the head command, not how rm handles SIGPIPE.

True, but most Python programs don't do this, so they pollute your terminal with error messages when you attempt to use them as interior processes in a unix pipeline.

> Saying python is "not a good Unix citizen" here is akin to saying cars are a bad highway citizen because people can crash them. I don't follow your analogy. The default signal disposition for SIGPIPE is to silently termi

In the unix pipeline model, components read input, perform some transformation, and print output. There is no need to do any clean-up. As nneonneo explained, because they rely on SIGPIPE, most unix programs don't even need to check for
