onedognight — Fri, 27 Mar 2026 10:03:06 +0000

Having the equivalent jq expression in these examples might help to compare expressiveness, and it might help me see if jq could “just” use a DFA when a (sub)query admits one. grep, ripgrep, etc change algorithms based on the query and that makes the speed improvements automatic.

New comment by onedognight in "How to defer US taxes"

If I have X dollars and get taxed such that I have X * T after the taxing, say T = (1 - .20), then I invest and that money grows by a factor, say G = (1 + .50), over the years, then in the mean time inflation hits and reduces my money by a factor, say I = (1 - .10), so that what I end up with in the end is F = X * G * T * I. If instead I invested and grew and inflated and then got taxed, X * G * I * T, it would be exactly the same. Multiplication is commutative.

What you are doing by delaying taxes is hoping you have a lower rate later. Say you make less in retirement or die untaxed and your kids get a step up in basis. But without a change in rate (which might go up even), there’s no difference.

You are joking, right? Project 2025 has achieved 50% of its goals in record time[0]. Trump disavowed both it and invading Iran, but make no mistake. Both were “the plan”.

Prop 13 isn’t the reason old people hang on to their property. You can downgrade and maintain your Prop 13 tax advantage.

They are, finally, part of C++20.

I fully agree. Claude’s review comments have been 50% useful, which is great. For comparison I have almost never found a useful TeamScale comment (classic static analyzer). Even more important, half of Claude’s good finds are orthogonal to those found by other human reviewers on our team. I.e. it points out things human reviewers miss consistently and v.v.

It’s loses them in the current context (say 200k tokens), not in its SQLite history db (limited by your local storage).

For this model to be convincing, you would need to explain the motivation for the pension funds loaning the 90% that then goes to zero. They are repeat investors after all. As are the PE firms.

Are they getting kickbacks? That would be straight up illegal, but it would make the most sense.

The machine (AirSense 11) has been a god send for me. I can’t believe I waited so long. I haven’t slept a night without it since my first. I haven’t had to tweak any settings. It’s just worked. Sure it’s annoying to travel with, and you look odd while wearing it, but deep sleep is so worth it.

It’s a bit clickbait-y, but the article is short, to the point, and frankly satisfying. If there is such a thing as good clickbait, then this might be it. Impressive work!

This is a great result[0]:

> we found that there are 17 semantic rules in the core semantics which are not covered by the [ECMAScript Conformance Test Suite]

> we succeeded to manually write test programs that hit 11 out of 17 behaviors

> the remaining 6 semantic behaviors are infeasible, that is, they represent flaws in the language standard itself

onedognight — Mon, 03 Nov 2025 21:31:48 +0000

The pep didn’t mention considering reusing `async` instead of `lazy`. That would’ve conveyed the same thing to me without a new keyword, and would haven’t been similar to html’s usage `async`.

Yes, but these examples are not zero-sum. There is no net winning for society from gambling zero-sum, whereas there can be from risky startups.

Here’s my solution: clicking four boxes that form the corners of a rectangle will flip them leaving the rest of the board unchanged. Using this move you can find sets of rectangle corners with more white than red and just click them. This will converge to a solution. If you can find a symmetric board where all rectangle corners have equal red and white then this method would fail. I haven’t found one yet.

EDIT: I found some positions where this technique cannot be directly applied.

It may not be clear from this article, but the Math Academy program in Pasadena Unified has the students in their tract taking the Calculus AP at the end of middle school. It’s a breath of fresh air in a public school system that often leaves the more advanced kids bored.
