aj7··on Microsoft Is Dead (2007)
That’s all fixed.
aj7··on Microsoft Is Dead (2007)
I don’t know. I just had to buy, and use, a Windows 11 pc. Remarkably, it shares a desk with a new M3 iMac, side by side. And equally remarkably, they’re set up so they behave almost identically, except that Windows 11 is a little snappier and has a few fewer keystrokes than the Finder for most operations. (And search works!). I quickly acculturated to it after a decade away. Entirely unexpected.
aj7··on Microsoft Is Dead (2007)
About two weeks ago, I had an epiphany that ‘Apple was dead’, since any cheap crappy device could act as a terminal to an AI infrastructure delivering a perfected and idiosyncratic user interface. Now, I’ve reconsidered.
aj7··on Round Rects Are Everywhere
In day camp in Brooklyn, we always had woodworking. In successive summers, we had an instructor who wanted us to round the corners and edges of everything, and another instructor who insisted we keep everything as square and sharp as possible.
aj7··on Round Rects Are Everywhere
Yeah, but how?
aj7··on Silicon Valley's best kept secret: Founder liquidity
Founder risk is total myth. I was at a startup where, when it was apparent there would be no more funding, the vc’s permitted principal founder to essentially embezzle the remaining few $M. He and his cronies then lived off the proceeds for the better part of a decade in a kind of “brown dwarf” of a company of the same name.

And it was the SECOND time he had done this in his career!

aj7··on A breakthrough towards the Riemann hypothesis
What if an airliner or a spacecraft or a self- driving car or a surgical robot breaks?
aj7··on A seventh-grader student found a beautiful proof to Thales' Theorem (2002)
No parent can “train” a kid to be a math genius. There is a wide divide between a “math genius” and having a high SAT score for instance.
aj7··on Volkswagen Group brings electric car for EUR 20k
Check reliability of current VW models before purchasing.
aj7··on The Evolution of Lisp (1993) [pdf]
Paul Graham felt all development should be in Lisp. Problem is readability by maintainers in the future. To facilitate that, the number of characters in the comments would have to exceed that in the code.
aj7··on The Evolution of Lisp (1993) [pdf]
Lisp is far and away the best of the nonreadable programming languages.
aj7··on The case against dual axis charts (and what to use instead) (2018)
No. You’re missing two arrows, each near its graph and pointing to the corresponding y-axis. This has more impact than color matching.
aj7··on AMA: I'm Dave Greene, an accidental expert on Conway's Game of Life
Just leave physics out, and you’ll be OK.

God doesn’t play the GoL.

aj7··on Cubic Life: Conway's Game of Life in 3D
Imagine. And all that work trying to derive physics from TWO dimensional finite automata.
aj7··on The Americas Act and Its Chances of Becoming Law
While the considerations that this act addresses are real, strategically, the act looks so stupid, ineffective, and contrary to market forces, and the sponsors so obscure, that it is suspect.
aj7··on A disgruntled federal employee's 1980s desk calendar (2018)
Inadvertently -> advertently
aj7··on Physically attractive attorneys tend to have greater success in federal court
Not by me.
aj7··on Starting today, ISPs must display labels with price, speeds, and data caps
I’ve asked this before. I’ve noticed if my speed is slow, and I test it a few times, (I usually use the Netflix-owned site,) my speed rapidly improves. Do ISP’s throttle service, DETECT your visit to speed testing sites, and THEN speed things up?
aj7··on Is the frequency domain a real place?
The DFT has quite severe limitations that do not appear in the Fourier transform. In particular, the Nyquist criteria that there be zero signal energy for ALL frequencies above half the sampling frequency can only be approximated, and must be accomplished BEFORE sampling, i.e. in the time domain.
aj7··on System/360 – CHM Revolution
Here’s the manual. I remember being in awe of this stuff when I was 19.

aj7··on How well can LLMs write COBOL?
A while back, I asked a question here, roughly, why hasn’t someone written, say, a C to COBOL translator? Such a program might take a lot of work, but it seemed to me that with an impending dearth of COBOL programmers, there would be demand for such an app. I was informed that there were so many different COBOLs in use that the output of such a program would STILL have to be tended to by an experienced programmer in the output dialect desired. This is just the Copilot situation.
aj7··on X-Ray Inspection in the Semiconductor Industry
Experience has shown that a number of people win repeated lottery scratch-off jackpots with a statistically impossible frequency. My hypothesis: After-hours use of semi X-ray inspection equipment.
aj7··on OpenCat: Open-source robotic pet quadruped framework
But live cat ships with much better software. It’s not close.
aj7··on An all-optical general-purpose CPU and optical computer architecture
um is huge.
aj7··on Superiority (1951)
The B-29. Nukes? Are you kidding me?
aj7··on An all-optical general-purpose CPU and optical computer architecture
Good point.
aj7··on An all-optical general-purpose CPU and optical computer architecture
I think the wavelength of light is a physical brick wall.
aj7··on Compressing chess moves for fun and profit
Position to position. 12 bits. Plus occasionally, an extra 12 bits for promotion. Promotion found by impossible position prefix. Whether it’s a capture, check, castle, what piece, etc. all interpreted by a reader program. What am I missing here?
aj7··on An all-optical general-purpose CPU and optical computer architecture
You are confusing geometry, and the excitation traveling through that geometry.
aj7··on An all-optical general-purpose CPU and optical computer architecture
But it needs SPACE, on the order of a few um minimum, that cannot be occupied by other devices.
