   Which one? Remember the decimal IEEE 754 floating point formats exist too. Do folks in banking use IEEE decimal formats? I remember we used to have different math libs to link against depending, but this was like 40 years ago.

   Since it was Hangul day yesterday, I was thinking about a project I did in the previous decade to pack Korean fonts into the flash of an LPC1768 Cortex M3 MCU. It was a deep rabbit hole.

   I can't put my finger on it, but there was something more accessible when you had a physical catalog in your hand. I am not knocking modern online catalogs, which are great when you know what you want. Take Digikey, for example, often

   Does this Python decimal mode use IEEE 754 decimal mode arithmetic (assuming any modern floating point hardware supports it).

   I've often wondered if serial computers could have a useful role again. At very high clock speeds and wide data paths, you hear about trouble controlling signal skews. In contrast, imagine a serial computer clocking data around at 8 GH

    If anyone is old enough to remember Joe Campbell's "C Programmer's Guide to Serial Communications", there was an excellent ASCII wall chart, which used these symbols for the control characters.

    Those teletype machines did need extra time to perform the two distinct actions associated with EOL, that is, the carriage return and line feed. Line feed seems like it would take a fixed amount of time, but CR could be pretty long if the c

    I did this for Hangul years ago on an embedded video OSD system to save font ROM space. But this composition of letter into syllables is fundamental to how Hangul works. Once I had rediscovered the old “Johab” concept of making the syllable

    I made something similar for OpenScad, back before it added support for text. It was like a really simple Hershey font, but using only line segments and circular arcs (no ellipses), because that was the path of least resistance. https:&#x2

    I remember when all the basic non-smart phones, like the few Samsung flip phones I had when I first moved to Seoul has this very basic ability. This feature was been dropped in the transition to smart phones for some reason.

    Back in the early 80s, on an TTY connected to the campus CDC mainframe, I learned the hard way that the editor command "222d" does not delete line 222. Rather, it deletes the next 222 lines in the file!

    So for example, if a diligent company offered a DRM removal tool, perhaps in escrow, for its media for which copyright had expired, it would be breaking the DCMA. Can DRM media be considered to be in the public domain if it is locked up by

    What provision does DCMA have, if any, for removing DRM when a copyright expires?

    Sad to hear this. I bought quite a few slide rules from the years from him. I even had an outstanding wish-list (of one) for a particular circular slide rule I had been dreaming to own.

    ANSI sizes F and above define various standard “roll” sizes. I’ve never had a need for roll format, but I’ve wondered what the ISO equivalent was. Wikipedia says these were used for full-scale layouts of aircraft parts, automotive parts, wi

    This is true if the ANSI A/B/C/D/E series as well. It’s just that the successively smaller pages don’t have the same aspect ratio. The square root of two is the key point.
