strtok() happily punches those holes in. Now you could argue, the resulting strings, while null-terminated, aren't true substrings (as the origin string is now corrupted), but in the context of parsing (particularly here using white-s

I appreciate the intro, motivation and comparison to the PIO of the RP2040/2350. How would this compare to the (considerably older, slower, but more flexible) Parallax P8X32A ("Propeller")?

Even if it's the same data, the bit stream will be a variety of 0 and 1s. The period of that waveform will then be 1 frame length / data transfer rate (or rather 1/4 frame length / data transfer rate as this is a QSGMII

Telephone line modems were always slow compared to the microcomputers of their day. A 14400Baud modem will just send less than some 1.5KB/s. Even a Z80 could handle a few streams of that. I rather suspect this BBS offered fancier se

Why stop there? Why not demand proof of correctness? After all, that's now within reach using LLMs producing the formal specification from a simple prompt, right? SBCL does a fine job in detecting type mismatches within the frame of AN

To pile up another anecdote: late in 2018 I put a well used PC with an Intel SSDSCKKW240H6 (240GB SSD in M.2 form factor) in storage and picked it up 5 years later. The SSD was unreadable then. The PC (with a different storage system) st

That also implies that NIL cannot be represented as 0, which is a pity since testing the Z flag would be quick. I'd think someone ran the numbers and found the chosen encoding superior, but that would have been long ago (in the CMUCL

An oscilloscope is the wrong tool for that. You can tell the difference between kind-of-square and kind-of-sine wave using one, but hardly more. At least DSO often have a FFT option and on the new ones with 12bit ADC that might actually be
