I'd imagine there is fairly wide gap between having a simulation engine core and an useful engineering application From academic side, I've found the work of Steinberg in this area extremely impressive. They are pushing the fronti

Liberation/Croscore fonts are more relevant here because they are designed to be drop-in replacements (metrically compatible) for MS fonts. https://en.wikipedia.org/wiki/Liberation_fonts https://en.wiki

Another note for simplification, you could use the builtin i2c peripheral and give each octet of leds its own address. You got 64 octets in total, which conveniently fits into 7 bit i2c address space. That should make the communication triv

If you are going to add your own sensors and feedback, then isn't using a servo kinda pointless, might as well go with plain dumb motor? I thought the whole point of servo is to have sensor+feedback+motor in a integrated package

Not sure how you reached that conclusion. The linked STELLA paper describes many post-Apollo improvements, both improvements implemented in STELLA, and star trackers like OWLS and AST 201. And it's not like progress stopped even there;

SQL nulls in some ways behave in similar to floating point nans. Of course nans are also weird in their own way, but it is a bit comforting that its not so completely singularly weird.

Otoh the flexibility of Linux networking stack makes it so amazing; if you can imagine it then there is almost certainly some way of doing it with Linux. It might not be fastest or cleanest, but it certainly can do a lot. Also, policy based

You can connect two computers with usb and setup network between them, so you can just use smb/cifs. Microsoft has even handy tutorial for that: https://learn.microsoft.com/en-us/windows-hardware/design/c

Almost every clock based on mechanical escapement stops hands on each beat. That is where the ticking noise of classic mechanical movement comes from. For quartz clocks, smooth sweeping hands is a premium feature and I'm not sure are e

At some point the AST needs to be serialized as bytes on disk. In the big picture, the cost of having that serialization format be also human readable is relatively small as long as the syntax is designed to be sane (i.e. not c++/perl)

Doesn't that depend on where the network is demarcated, i.e. is ONT/ONU considered to be on "ISP side"?

It seems bit odd to call it most accurate pendelum clock if the accuracy stems from being disciplined by atomic clock. To me the interesting question would be how far can you push the freestanding accuracy of a pendelum clock. That is not t

In case you like these sorts of things, I think Micro Journal from last year is really neat device. Small portable linux computer with nice mechanical keyboard, and boots directly to wordgrinder, a small terminal-based word processor to off

I use similar setup on Windows (with vmware/virtualbox/hyper-v at different times), which kinda highlights one additional upside: it doesn't matter that much what the host system is, you can do your work all the same regardle

To be more pedantic, doesn't that depend on your choice of coordinate system?

> Here “tropical year” means the time it took earth to orbit the sun from the perspective of the “fixed stars,” Isn't tropical year relative to sun, i.e. equinox to equinox? And sidereal year being relative to fixed stars?

One thing that saddens me is how Ragel petered out, I guess they got bit too ambitious with the Colm rewrite. But it was a state machine language that saw a blip of usage at one point

Ocaml might have lot of faults, but I can't see it being overly puristic or minimalistic.

Isn't Propeller bit problematic from educational point of view because it's design is so unique that knowledge from it is not so readily transferrable to mainstream hardware?

I don't know if it needs to be smoothly varying instead of having just two zones with a step between them. Either way, I'd expect it to need significant amount of processing to get anything useful.
