The EGA color situation isn't as bad as the author described. CGA had a 16 color palette. In text mode, every character could be rendered with the background and foreground of any of the 16 colors. In graphics mode, you had to select o

If you think DotA2's matchmaking is unfriendly to new players, I don't think you ever experienced DotA1 matches. Every single game was wildly unbalanced, and as a result of one or so players, every single game was an absolute stom

I would expect the unmount of an encrypted filesystem to secure delete the encryption key from memory. My understanding of the memory freezing attacks is that you don't unmount it, you just kill the power by removing the battery. With

When I was in boy scouts, at one of the camps one year one of the people running the thing had this little game. The idea was that two people would each tie a bowline around their waist, and connect the two ropes with a square knot. Then do

I don't think I've ever seen someone use M, NM, or nmi for nautical mile. I've only ever seen nm. I used nautical miles a lot in a previous career, in the context of aircraft mission planning. Telling people in the industry t

The point is that a one millisecond pause is unacceptable. Low latency Java GCs have average latencies of one millisecond, 99th percentile latencies of 10 milliseconds, and 99.9th percentile latencies are neither measured nor optimized for.

pandas can read from a CSV file and then write to SQL. Even if you don't go the SQL route, you'd probably gain significant benefits by working with HDF instead of CSV. https://pandas.pydata.org/pandas-docs/ver

> x86 is a lousy architecture, but x86-64 isn't as bad; at least it has a good number of registers unlike x86. Funny thing. Whether you boot a modern x86 system in 32 bit mode or 64 bit mode doesn't change the number of registe

I mean... sure? But what's the point, what low level languages are there? The linked article is arguing that C isn't low level because modern CPUs behave so differently than what their hardware interface suggests they do. If we ac

Following the metrics if the article, assembly language isn't low level either. Assembly language only gives you access to 16 integer registers and the 16 (?) sse/avx SIMD registers on x86_64. It doesn't give you access to th

Unless there's something I don't understand, that's what the single static assignment pass does in a compiler.

I don't understand. What does the "single assignment" bit get you that a compiler with an SSA pass doesn't?

Fighting games like SF2 usually work on 2D hit boxes. [1] You have boxes which are defined as things that do hitting, boxes which are defined as areas that can get hit, and boxes that define clipping. If a do-hitting box overlaps a get-hit

Maybe. If you have 4-8 static blocks vs 16-32 attacks that would be fine, but if you need to calculate what happens when 16-32 attacks run into the same 16-32 attacks you have a combinatorial explosion problem which you then need to simplif

I'm aware. I deal with rotations and intersecting geometries at work too. There's a closed form 3x3 matrix inversion procedure which is very fast on CPUs. [1] We don't use it with pen and paper because it's too hard to r

Spitballing here. Model a sword as a point of rotation e, (elbow, shoulder, whatever, have the animator figure it out) location of the tip point p, and the linear velocity vector v of its tip. Look at the letter 'F': The elbow is

The bit about making nuclear weapons from thorium by products is both true and false. It is true that bucket weapons can be made from uranium 233, but not really. Right now, when we make nuclear weapons from plutonium 239 and uranium 235, i

Depends on whether or not you use roundabouts. Roundabouts are no worse with six (or eight) way intersections than four, but six way traffic lights don't work, and even four way traffic lights are problematic. Cities: Skylines. To a ce

Linear algebra lands in my professional lap surprisingly often, to the point where I ask myself if it's a linear algebra problem fairly early on in the problem solving process. (I'm in GIS) Calculus is unusual, but it does happen.
