And then you get warnings about structures being padded and warnings about structures not being padded.

At my previous job, I was the youngest person in my group, at 52. The others in my department were alkl developers (even my msnager, who was a developer turned relunctant manager). Many of the other developers were 40+.

There was an early 8-bit home computer where you could reprogram the video controller chip to drive the TV/display out of its operating range (timings/video frequencies, etc.) where left too long (how long? I don't know---I&

I was in a small town in North Carolina and stopped off at an antique store. There, I saw two slide rulers for sale, each for $15. I immediately bought both of them, and one of them was a Pickett N600-ES (of the four slide rulers I have [

Not every CPU C runs on has a carry bit. MIPS, SPARC, RISC-V, all don't have the concept of a "carry bit."

But ... but ... but ... my keyboard has this "escape" key! Why doesn't that let me escape the current program? Oh, there's this "break" key! That doesn't seem to work. And why do I have to use Ctrl-D w

Nice in theory. I recall a few years after leaving university talking to a few friends who worked there in the Computer Science department. They would regale me with tales of students who would constantly complain to the dean that the assi

The only comment I have is about the first footnote. The 6809 had a MUL instruction, which was 8b unsigned only (register A * register B, high byte of result in A, low byte result in B). There is no DIV instruction.

And aside from one <svg> block and one <table> block, all the tags are either <div>s or <spans>s. That's ... impressive.

If your hand is cramping up, it's probably due to holding the pen/pencil too tightly, or applying too much pressure to the paper. If I use a ball-point pen (the most common type) for too long, my hand cramps up because of the pre

I once wrote a calculator that has five output displays: signed decimal, unsigned decimal, hexadecimal, octal and binary. I did it that way because I was tired of having to select the output mode. I also added the ability to select 8, 16

That's not a fault of MS-DOS, but of the application writers. If they stuck just with the MS-DOS API, the app would work with any MS-DOS machine.

In my opinion, the simplest explanation of this is: a worker at the Wuhan facility was accidentally infected (mistakes happen) and it was able to spread. It was not intentional.

I have magazines for a not-terribly-popular 8-bit computer, the Tandy Color Computer, that regularly exceeded 200 pages, and that was one of about four magazines devoted to that computer. There was no Internet back in those days.

I recall just ignoring ads when I read magazines, but now, when I go back, it's interesting to see just what was being advertised, and the price of items ($200 for 64K RAM! Cheap!).

I worked in that space for over a decade. While it's true, the use of E.164 in production was never done (usually, it's some subdomain from the Oligarchic Cell Phone companies). Second, it's never free. Nothing on the tele

There were two memory upgrades. The first was a card that plugged into the motherboard. The other one was an expansion module that plugged into the side of the computer (and multiple of those could be used). My PCjr had 384k of RAM, usin

It may seem weird, but the Tandy 1000 copied the graphics modes from the IBM PCjr, not the EGA standard. That included a 320x200 16 color mode, as well as 640x200 four color mode that the original CGA couldn't do (because it lacked me

The Tandy Color Computer did not have such a chip, but it did have a 6-bit DAC (Digital/Analog Converter) that could be used to both sample and play back sound. Yes, it was CPU intensive, but you could get some pretty impressive resul

You just need a decent assembler with macro support. Here's a few lines of code I have for 32-bit x86 code: PRINTF "main_task: sf=%p",ebp PRINTF " sf: 1=%d 2=%d 3=%d 4=%d",dword [ebp+8],dword [ebp+12],eax

The Apple Macintosh was released in 1984. Jobs was pushed completely out of the company in 1985. When did RezEdit, Hypercard and AppleScript come out? Without looking it up, I would say after Jobs left Apple.
