colomon··on Getting back into C programming for CP/M
Forth! I was programming in those days myself (though only a little bit on CP/M), and was getting surprised that many people here seemed to think the only alternatives were C or assembly. I learned to program in Basic, then learned some assembly, and finally discovered Forth circa 1984. It was perfectly suited to developing on 8-bit machines -- about as powerful as C, trivial to compile, easy to drop into assembly if you needed to optimize a low-level function.

If I remember correctly, I didn't learn C until 1989, when I was working on 16-bit machines...

colomon··on A Git story: Not so fun this time
People started paying me to develop software in 1986. First time I ever used version control software was 1996. It was TERRIBLE. Two years later I left to start my own software company, but my experience with it to that point was so bad I went without version control the first few years. Around 2002 I started using CVS (or RCS? long time ago!) and quickly switched to Subversion. After learning git to work on Raku circa 2009, I switched my main $WORK repo to git in maybe 2012. Every repo I've created since then has been in git, but I still haven't moved all my svn repos over to git.
colomon··on Do not taunt happy fun branch predictor (2023)
I don't remember the exact numbers, but I remember seeing a CAD file that was not working well a few years ago, and it turned out the coordinate system set up for the part was roughly equivalent to building a part the size of a man's fist but measuring it from the center of the Earth (in meters) while putting the part in Earth orbit.
colomon··on Apple Silicon MacBook batteries can't be replaced under warranty by third party
AppleCare+ is usually 48-hours downtime in my experience, and that's with the need to ship the laptop to and from the repair center.
colomon··on The Genius of Ella Fitzgerald
I've listened quite a lot to her Rodgers and Hart songbook, and the idea she doesn't understand what she's singing never once entered my mind.
colomon··on Baltimore's Key Bridge struck by cargo ship, collapses
First span of the Blue Water Bridge (Port Huron to Sarnia) built 1938, doing just fine as far as I know. (Drove over it a couple of weekends ago.) Second span was 1997.
colomon··on HP CEO Makes Up a Whole Lot of Bullshit to Defend Crippling Printers
Was just looking at buying a new printer a few minutes ago. Do people have recommendations for printers free of all this HP-style nonsense?
colomon··on Recoil – Retro Computer Image Library
Ugh, now I'm torn between wild urges to write a Raku backend for Fusion or port my C++ libraries to Fusion, neither of which is anything like a sensible project in the short term. (Possibly any term.)
colomon··on America’s Obsession with Weight-Loss Drugs Is Affecting the Economy of Denmark
That "not changing habits" thing has nothing to do with Ozempic. Based on my experience with the drug (taken six months for type 2 diabetes), you won't lose any weight at all on it UNLESS you change your habits. What the drug does is make it easier for you to change your habits!
colomon··on Ask HN: Are you using Raku? Pros / cons?
I've been actively using Raku for work for 13 years now. (Okay, we didn't call it Raku yet at the beginning.)

Pros: - Wonderfully expressive and powerful - The best glue language I've ever worked with - Indented heredocs (I think Perl 5 has this now? But Raku's had it for a decade, and it's made a number of my scripts vastly more readable than their Perl 5 equivalents.) - Great community that responds quickly to questions

Cons: - Every few years one of the platforms I've got it running on gets far enough behind that the module manager stops working with it, and I've got to install a fresh version on that platform

Most recently, on Saturday I wrote a script to valgrind a batch of files whose name starts with a string you provide, carefully recording any valgrind errors detected. 37 lines of clean code, easy to write, and hugely useful for my current project. Have had it running more or less continually for the last 24 hours...

colomon··on Ask HN: Did studying proof based math topics make you a better programmer?
I think the proof mindseet was a huge help to me as a beginning programmer, BUT that was in the context of high school Euclidean geometry, not analysis, around the same time I was first learning a programming language that let you write functions. As I recall (long time ago now!) the two things kind of fed off of each other very nicely.

Then it got a bit of reinforcement in my honors "1st semester calculus but we're proving everything" course.

colomon··on Refurb weekend: Commodore 128DCR
I loved my Commodore 128, but I don't even remember a Commodore 128D being a thing. I suppose at that point I may have been fondly dreaming of the Amiga I would never get.
colomon··on Lidar Reveals 650-Square-Mile Maya Site Hidden Beneath Guatemalan Rain Forest
Ooo, I'll have to look into that. I had a fun couple of days a few years ago comparing Google Maps satellite images from St Clair County, MI with the old maps which showed where the Interurban ran. It was really impressive how much you could still see the routes from above, even though the tracks were torn up 80+ years ago...
colomon··on Normalization of Deviance (2015)
First professional software development I did, we didn't even have hard drives or networking. Luckily I was the only developer and it wasn't a huge problem.

First place I worked with other people, we at least had hard drives. I don't think we had networking on the machines or version control. For sure there was only one or two machines in the office that could reach the Internet. Mostly only one person could work on a file at a time.

When we did get more employees, a LAN, and version control a few years on, the mid-1990s Microsoft version control software was such a piece of junk it mostly amounted to a formal digital system specifying who the one person who could work on a given file was...

colomon··on Weimar Jazz Database (WJazzD) – The Jazzomat Research Project
Weirdly enough, if I cam to believe Discogs got the liner notes faithfully, they're not crediting Jon with singing a solo on "Airegin". I'm still 99% certain Jon sings the last solo in that song. (Interestingly, singing lyrics over his own scat solo from the original Lambert, Hendricks & Ross recording of "Airegin".) For sure it sounds like him, no one other than Manhattan Transfer is credited with vocals on that track, and when they recorded it live they don't even attempt to sing it, replacing it with a sax solo.
colomon··on Weimar Jazz Database (WJazzD) – The Jazzomat Research Project
I was wrong about "Another Night in Tunisia" -- the solo Jon sings starting around 1:40 actually has lyrics. I think the melody scatting for most of the rest of the song is actually Bobby McFerrin.

Oh, there we go, the scat solo starting at 2:30 in "Ray's Rockhouse" is Jon.

colomon··on Weimar Jazz Database (WJazzD) – The Jazzomat Research Project
He wrote the lyrics for that entire album (Vocalese) and sings on it too -- one of the solos on "Airegin", and a scat solo somewhere else (maybe the Night in Tunisia thing, been a while since I listened).

He also wrote the lyrics for their versions of "Birdland" and "Four Brothers", and maybe four of the tracks on Swing, and probably a bunch of other stuff I'm not thinking of.

Oh, the blog post there is lovely. Just used the lyrics to sing through "Sing Joy Spring" while listening to the original Clifford Brown recording.
colomon··on Weimar Jazz Database (WJazzD) – The Jazzomat Research Project
"Sing Joy Spring", lyrics by Jon Hendricks. Jon wrote lyrics to dozens (hundreds?) of jazz solos. Was one hell of a singer, too -- check him out singing John Coltrane's solo on "Freddie Freeloader" [1]

colomon··on Scamp – A self-contained Forth computer
Indeed, it's zero now, 15 minutes later.
colomon··on Jazz Is Freedom
Ha, pretty sure I heard Jon Hendricks sing "In Walked Bud" live, but never had a recording of it. Thanks for the tip on that it was on Underground!
colomon··on Ask HN: What was being a software developer like about 30 years ago?
30 years ago was right around the time I wrote JPEG viewing software so I could look at JPEGs on my computer. :) I mean, I got the actual JPEG decoding from whatever the standard open source implementation was at the time, but then paired it up with my own code to display to my graphics card, which could handle a rather fancy 32K colors. Then I could view JPEGs downloaded from Usenet.

Those were my college years. Prior to that, in the mid-80s I developed in Forth / 6502 assembly on my Commodore 128 at home, and QBASIC (sigh) on IBM PCs at work. After college, we were programming in C++ on Gateway PC clones -- had one at work, and a slightly less powerful one at home. A helpful co-worker introduced me to Perl, which quickly became an essential tool for me. Around this time we finally had version control software, but it was terrible.

colomon··on The Commodordion
Geez, was the "open source" link there all along and I just missed it? Thank you!!
colomon··on Om is a novel, maximally-simple concatenative language
Right? Its creator obviously knows Forth, but it feels like they've gone to extreme lengths to make it prefix rather than postfix, at the price of making it much more confusing than it needs to be? It's really not obvious to me that if they were both equally complete, there'd be any advantage at all to choosing this over Factor...

(That said, I did a lot of Forth programming in the old days, and while I am utterly intrigued by Factor, I've never managed to write anything useful in it...)

colomon··on The Commodordion
This is a fantastic idea! I had no trouble playing scales along the row.

Is the source code available? As a C#/D player, I find the relationships between the rows unfriendly, and miss the bottom two buttons of the row. Plus I'd love to have real accordion sound samples, and maybe MIDI output...

(ooo, plus I guess if you only wanted two rows of right hand notes, then you could have two rows of bass buttons, just like a real box only with a lot more chords available...)

colomon··on Man plays his saxophone through 9-hour complex brain surgery to remove tumor
I obviously cannot speak for everyone, but when I play music from memory (and yes, often with my eyes closed) there isn't any visualization at all. It's all a combination of sound and muscle memory. Indeed, for plenty of music I would never have seen sheet music to be visualizing...
colomon··on Why are D-sharp and E-flat considered to be two different notes?
Friends recorded this album --https://alisonperkinsandnicolasbrown.bandcamp.com/album/all-... -- with A somewhere in the neighborhood of 360Hz.
colomon··on Why are D-sharp and E-flat considered to be two different notes?
As far as I know it applies to both brass and woodwinds, though the degree of difficulty involved probably varies between types of instruments and also (at least on the woodwinds I'm familiar with) note to note.
colomon··on The Mensa Fallacy
On the one hand: article agrees with my vague impression of Mensa from a distance.

On the other hand: the study's conclusion that very intelligent people have elevated rates of autism spectrum disorders, depression, and generalized anxiety agrees very well with my up close and personal observations of very intelligent people.

colomon··on Retirement of Amazon MOBI eBook file format
"We wanted to let you know that starting August 2022, you’ll no longer be able to send MOBI (.mobi, .azw) files to your Kindle library."

That said, that was August 2nd and sending that file as MOBI did work.

(And the success e-mail message they sent me today said they did convert the Man and Superman EPUB to "Man and Superman: A Comedy and a Philosophy.azw3".)
