FORTH variation #1,000,001: I took John Walkers' AtLast as a core, and extended it in several directions, some I believe quite significant. My use case for FORTH has been as a live debugger that lets me interact with a running Real Tim

Too old for any one language to have lasted my entire career. But: C for (embedded(embedded))* audio DSP engine, with hardware specific intrinsics and occasional drops into inline ASM when those fail. When every cycle counts and Hard Real T

Existence proof. Can avoid ageism. But likely only via competence, creativity, and rep. I've been lucky, I guess.I would add to continuous learning: continuous invention. New stuff in the world, not just new to you. In my case, almost

Sharing data structures in RAM between 64 bit and 32 bit and 16 bit architectures brings this home painfully. Data communications is equivalently plainful, possibly moreso becaude one has no knowledge of the receiver's architecture. Se

The big loss is to musicians who use iOS for creating music. This involves several often expensive hardware boxes, such as quality audio interfaces and most modern synthesizers, none of which are USB-C compatible. So we are looking at much

Except that they are not doing that. The new emails came from the Weiner investigation, not the CLinton server.

This comes up approximately annually. I used to answer at length. But now at 69 brevity seems more productive. I am probably nearing the end of my accidental unplanned drunkard's walk career, one that start in 1967 when I was dropped (

Not "wrong" - just fractally revealed details. What I find amazing here is thatit shows the fractal nature does not only work by looking into ever smaller regions - we also are discovering fractally larger structures exploring in

And he did that trip twice, with two generations of original systems - Wonnebago and Behemoth. Yes, Steve is indeed really cool. No contest.

Including seriously long and detailed code and algorithms and discussions about sam. I got a really nice byte based lookup table method for computing CRC16s (any feedback points) from a Byte mag in 1976. Don't see these today.

I always thought "lock free" meant no hidden pauses in execution - a write is a write and a read is a read. The primitives described here will block. How is that different in effect from a lock, albeit one implemented down in the

My own saying on this: "That which _can_ be configured _must_ be configured", corr: "Defaults Aren't". Inspired by my early experiences with early Windows 3.

Very misleading title. In fact, the last quote in the article is "Science isn't about truth or falsity, it's about reducing uncertainty".

My personal aphorism (for at least 20 years now): Warman's Law: That which _can_ be configured _must_ be comfigured, Corr.: Defaults Aren't. Impl: running any program on its defaults will get you in trouble somewhere down the line

"should": a problem with lengthy experience and age is just how many steps between A and Z get chunked into merely A to B since it is "obvious". Which, in my case, is why I do not teach. Ive forgotten too many derivation

But does not define them in terms of hardware. My numbers referred to the native widths of the hardware words. sizeof(int) would of course return those numbers divided by 8, but machines are almost universally referred to by bit width, not

One problem is, in C at least, the compiler has no way to know that the contents pointed to by p have reached their end of life. All these examples use malloc() and free(), but these two names are purely convention, and any names and memory

Biology has been used for NP-hard before. Travelling Salesman was run in a petri dish maybe 20 years ago IIRC. Answer was encoded in RNA fragment concentrations.IIRC again) the base sequence was the solution.

Back in 1975 I had a leather motorcycle jacket with a similar claim. It had a center lining of aluminised mylar (?) with some kind of white filament woven in and out of it. It was indeed very effective, and reduced the bulk of my inclement

The road to here is littered with Dataflow attempts. I am thinking in particular of the Transputer and the Hypercube, though I also came across several others that never made it out of the lab. I have a design bucket list of my own - back i

It can be much more than just a point or ray. One summer I was on an endurance motorcycle ride over the Los Angeles Mountains, altitude about 3500'. As dawn was about to turn into sunrise the entire sky flashed green. Lasted less than
