I feel that it's not such a clear distinction between whackamole bug fixing and systematic security engineering. For instance, he uses an example of recurring security vulnerabilities in Chromium: a DCHECK violation again and again and

Right!!! LLMs are yet another step up the abstraction ladder. Before LLMs I would write code in C or Perl; I didn't care about the machine code it eventually was translated into---the compilers/interpreters evolved to handle that

So it says that not ALL points are on that single line. But it doesn't stipulate that THREE points can't be on the line---the theorem is about proving that you can find one that doesn't have the third point.

In the interconnected, online world, you can do more damage without root access "they can read my email, take my money, and impersonate me to my friends, but at least they can't install drivers without my permission"

The clocks need precise oscillations to measure time: the mechanical clocks used pendulums and springs; the maser clocks used precise microwave cavities; the atomic clocks that are dominating today use oscillations of electrons in selected

Thank you, great info. You have great suppliers though: I can get close on batteries (I see four for $355, so $88 instead of your $70) but for panels the best I can get is $220 instead of your $32---how do you go about getting them at those

I don't doubt that you can have a low marginal cost, but you still have to invest money to get this system installed. You dismissed my argument as 'vague and hand-wavy', so please give a concrete estimate how much it would co

They say $0.01/kWh is the target price, to be reached after some decades. Don't get me wrong, I am excited about solar power but careful about the economics: the capital cost of solar right now is well over 1$/W (panels+inver

in sqlite you can do it with FILTER: $ sqlite :memory: create table t (product,revenue, year); insert into t values ('a',10,2020),('b',14,2020),('c',24,2020),('a',20,2021),('b',2

Good insight, but if you discount the visual elements (tabs, buttons, etc), you're limiting TUI to CLI, and I think that's unwarranted. The value proposition of both TUI and GUI is two-fold: you see the available action options, a

The compilers used to be unreliable too, e.g. at higher optimizations and such. People worked on them and they got better. I think LLMs will get better, as well.

Any competent computer engineer can design a much better ISA than RISC-V. Hello, my fellow bitter old man! I have to respectfully disagree, though. Firstly, RISC-V was actually designed by competent academic designers with four pre

A lot of computer users are domain experts in something like chemistry or physics or material science. Computing to them is just a tool in their field, e.g. simulating molecular dynamics, or radiation transfer. They dot every i and cross ev

Greg mentions discipline and vision as determinants of successful software, which is correct but I think he misses another aspect of vision: the ability to attract and crystallize a community around their project. Arguably, most successful

Great example, and a lost opportunity in the interview---they should have asked "What are the requirements that would invalidate this answer? and what would you design if the requirements were changed in this way?". Maybe even &qu

The alcoholic knows the bad outcomes, and chooses to ignore them. The hapless Android user does not understand the negative consequences of sideloading. I think this makes for a substantial differerence between those two.

Well, power envelope IS the limit in many applications; anyone can build a LOBOS (Lots Of Boxes On Shelves) supercomputer, but data bandwidth and power will limit its usefullness and size. Everyone has a power budget. For me, it's my d

Literate programming is not about programming in natural languages: it's about integrating code (i.e. the formal description in some DSL) with the meta-code such as comments, background information, specs, tests, etc. BTW, one side ben

I guess it would be a consumption-based tax. The usual argument against it is that it's regressive: the poorer people spend higher percentage of their income on consumption, and therefore end up with a higher tax burden relative to the

There's graph-easy, which generates ascii by default but can also do box chars, and even SVG and png, as well as generating graphviz and other output. It is not WYSIWIG---you feed it a description of a diagram: echo "[ Berli

Connections are the only one that can't be solved by either a regexp grep against /usr/share/dict/words or an LLM query. I was actually surprised how poorly LLMs fared against it---I thought they'd be better at

Most of the SBCs are supported by fairly standard Linux distributions: Debian/Armbian or Fedora; you just boot from the approriate image on an SD card. Some SBCs have eMMC storage and/or a M2 connector, so you can either keep runn
