If you tune two strings together, listening for beats, you are also guided by a moiré pattern. The whistle you hear when tuning an old AM radio is also moiré beats caused by the overlap of the local oscillator frequency and the incoming car

I have a wooden banana hanger that I designed using bezier curves, twenty years ago. Actually I made two; one of pine and another one of oak. I have the files somewhere, I hope; it was made using an abandonware vector graphics program calle

Using A as a root username would have to become massively popular before the cracking "community" began including it in their probing. After that, the Kj password might not hold up.

It is different when it is a well-known thing. If you see "toor" in a BSD password file, you know that's a BSD thing and not someone making a backdoor. I'm wildly guessing that the BSD flavors that have toor have patc

None of them apply to the situation of an individual operating an accessible system for their own use, or very small business with a handful of employees. The kind of organization where it would make sense to forbid tricks like multiple pas

AICPA should have spent 5 seconds on a web search to find out that SoC means System on a Chip, and chosen something else.

Giving a the most flimsy reason for the policy doesn't give me confidence in that; I can think of much better reasons for disallowing uid aliases (root or otherwise). It has the same optics as an unauthorized entry someone planted: a

I am not a corporation, so I don't need corporate guidelines. There isn't more than one UID 0. Only more than one password/shadow database entry pointing to it. (It might not be necessary; perhaps there is a way for OpenSSH t

You can't seriously match people on first and last name and claim "fully matched". Think of how manny John Smiths there are? How can this be the company started by Wozniak and Jobs ...

Honestly, I would feel uncomfortable if I were designing an instruction encoding and came up with some addressing mode format where there are two bits for a displacement. I would pull myself aside and have a word with myself. That's j

What I do is laughably simple. 1. Disable all logging about break-in attempts. 2. Do not have any common user names like "root". Say you want to be able to log in as root from anywhere, just with a password. This is a wise idea; w

It's more like this: We've always lacked understanding. However, it didn't feel like a bottleneck; in spite of lacking understanding, we developed huge, complex systems that became hard to maintain and that nobody understood

Simply those first three words out of an LLM would be a massive improvement: "I don't know". "I am not sure". "My confidence in the following answer is low due to a lack of reliable information in my training a

Generally speaking, whenever you trace into the old generation, you stop and back out. Given a young generation object with pointer fields, you don't know which of them are also young and which are old, unless you examine them, which i

When you get it working, you will figure it out. (Or even well before then; the rest is just bugs.) I wrote one for TXR Lisp which there are no generation heaps; but objects have a generation. In the same heap, you can have adjacent (unrela

In 1990s C++ we did: void foo::method(const &smart_ptr<thing> x) { ... } The smart pointer passed reference isn't copy-constructed and so no refcount is bumped. It has a scoped lifetime. The calling function owns a ref

I'm into Lisp because Lisp languages are easy to work in. I advocate the family as being good for nonprogrammers. Small children should learn some kind of Lisp, and easily can. Richard Stallman famously shared an anecdote in the articl

I would say, then, that Facebook is perpetrating fraud. They are knowingly defeating ad blockers to sell ad space that they know will not lead to any click-throughs and conversions.
