Yeah, I was just trying to keep to the letter of what you'd said - you asked for it just to use OpenGL/GLFW bindings, not other libraries, so I didn't want to install cl-opengl and…

"Please write me a program in Common LISP (SBCL is installed) which will render a simple "hello world" triangle in OpenGL. You should use only OpenGL and GLFW (using sbcl's FFI) fo…

In their own first example of English text rendering, it's mistakenly rendered "The silent patient" as "The silent Patient", "The night circus" as "The night Circus", and miskerned…

This article is literally the reason why people crave summary, because it was so content-free that it was a waste of my time to have read it all. It was a lecture extolling the vir…

RFC1459, the IRC one. I wrote the QuakeNet channel services once upon a time.

Comment #43695146
Yeah, it’s as if they wrote a program to calculate pi in a float and saved the output. Very strange choice given how many places the value of pi can be found.

Childhood exposure to pi generation algorithms; the correct version above was from memory.

Comment #43694599
For some reason the value of Pi given in the C++ code is wrong! It's given in the source as 3.14159274101257324219 when the right value to the same number of digits is 3.1415926535…

Some - not all - of the EF lenses have a distance encoder as well. It's fairly approximate; I think it exists mostly for the benefit of the flash system, which needs a rough starti…

Even your example of discharging a capacitor can end up with a pulse both directions, caused by the inductance of the wires. In this specific situation, there's no common reference…

Comment #41775219
Sign matters as well as magnitude. The pulse created will have both a positive and negative part - waveform sort of like --^v-- and so you can get either direction bit flip. It's n…

Thanks for the suggestions - I'll definitely have a poke at it in TDR mode, that's a good plan. Thanks also for the scikit-rf driver - I've an 8753ES as well, and I've used scikit-…

Comment #40743517
Thanks, it's really useful to have a reference point. Having played about a bit with which device is left to warm up, I'm fairly sure it's the 85102 (IF box) that's drifting. I've …

One of the few places you run into fellow 8510C users. How stable do you find your calibration on the 50GHz 83650 setup? My 20GHz one with the 8341B is very, very, very drifty for …

A dissenting opinion on the design - for me, this presentation was like watching a video to find information; too slow paced, and it made me impatient the whole time. The original …

On UK plugs at least, there are shutters and you need to insert something into the earth pin slot before they will allow you to access the live/neutral pins. On better sockets, the…

I keep an LTO tape robot around for just exactly that reason. I trust backblaze, but I don't trust them to the point of not writing off a weekly/monthly/yearly tape set.

So, after a few minutes on the site, I found a half-dozen private keys with several transactions, but zero balance. Is the key-space so densely populated that this is expected? Edi…

This is still pretty common in Scotland - I've done it mostly every year since I was a child. They give you a much creepier lantern than pumpkins do, but they can smell awful as th…

There's a proper reset procedure much like the GE bulbs too, though - On-Off at 3-to-5 second intervals 5 times.

I really like this, not just because it makes a good point on performance, but because it also provides a nice, simple, idiomatic example of a service with a custom protocol in pyt…
