For more 16-bit 65816 context -- other than for space-savings, these instructions are never used when performance is needed due to the low effective throughput of 7 cycles per byte. A basic unrolled loop using 16-bit instructions is 20 - 3

Having done plenty of interviews, it's surprising how many candidates list every technology they may have touched for the briefest of moments. For me, "grilling" someone on something like a programming language is about de

Mapping the stack to the graphics screen is also a staple for fast animation on the Apple IIgs. On pretty much all the micros of that era, stack operations would be the fastest instruction due to the auto-decrement behavior. If one could le

And if there are people specifically interested in console-style IIgs game development, I've picked up and significantly enhanced my old graphics engine that was used for the IIgs Super Mario Bros demo. It's available on github at

I get a kick out of these kinds of pure math problems where there's such a large gap between what is provable and what might be the best answer. "We can prove it can be done with 10^200 pieces, but it can probably be done with les

I remember a similar hack from 1999 posted on the venerable Slashdot on broadcasting FM radio using a memory bus as the carrier.... Ah, here we go, thanks to the Wayback Machine: https://web.archive.org/web/200104192259

It depends. In Minnesota, wearing any of the items you listed would be considered electioneering if that was a major issue of the campaign. So if one candidate has made gay rights a major plank of their platform, then wearing a shirt with

I could hear a fait beeping in one corner of my kitchen, but if I moved ~3 feet in any direction it disappeared. Eventually discovered that it was some kind of acoustical beat frequency from the motor noise in the refrigerator reflecting of

Related to this — Wells Fargo was sued[1] (and lost) around 2010 for the practice of ordering daily transaction to (indirectly) maximize fees and penalties. In your example, a “good” bank would order the transactions: +$50, -$25, -$25 resul

This definitely adds some useful nuance. I certainly understand that when expertise in topics A, B and C are necessary to get in the door, you do the best you can. Getting a handle on the basics of a tertiary topic so you can start the con

There's a kind of limbo zone where non-bullshitters internalize bullshitting as the normal pattern of communication and that's where the damage can really happen vis a vis genuine competence. A manager might sit down with their

That’s a good question. According to their public documents, they plan to source shrimp larve from Sea Products Development, LLC, which is also located in Texas. Nothing on the SPD site contains any direct information on this issue, other t
