  • It kinda comes out of the experience. There’s an outstanding Github issue that notes that a specific version of YT Music is broken past a certain version. Most of the patches fail to apply and you just get the minor ones. You can use the version just before with no issues. How can you litigate against lines of code that don’t even work? This is similar to the vulnerability that Yuzu gave up since they offered Patreon-exclusive updates to support a leaked BOTW:TOTK .iso. Easy to prove your intent there.

    So it’s not that the Volkswagen cheated on the emissions test. It’s that running the emissions test (as part of the building process) MODIFIED the car ITSELF to guzzle gas after the fact. We’re talking Transformers level of self modification. Manchurian Candidate sleeper agent levels of subterfuge.


  • I’ve got a Linux work server because VHDL simulations are hella expensive. I have to say that if your team isn’t willing to RTF-Man pages, you end up with a lot of cargo cult CLI processes. No crystalized knowledge or training, it’s hard to start up in it. It’s enough that requiring explicit Linux experience for new hires is preferable. Windows sadly has the familiarity benefit. And don’t get me started on the wacky custom solutions the IT set up circa 2002…



  • It’s physics for computers, specifically the Direct Stiffness Method. The formal definition of what you send into a computer for stress analysis involves a whole lot of matrixes. You turn a structure into tiny little nodes not unlike pixels or voxels. Each point can be connected to other elements, and these connections have unique internal linear or twisting “stiffness”, like a spring has. Think how a spring and a stick of wood resist squishing and bending. They can be expressed as one massive square (important!) matrix. The equation in the third panel is essentially a mega version of Hooke’s law:

    F = ku
    “The vector of forces on the nodes = the matrix containing all information of the stiffness of the connections * the vector of positions of the nodes”.

    This is a linear algebra problem, the easiest type of problem for a computer with a GPU. We can insert the known positions and forces on the bridge and solve for all unknown positions. If a truss on a bridge is calculated to experience too much force than it can handle, you can say that the bridge will fail under those conditions.


  • Your Only Move Is Hustle! YOMI Hustle for short. Turn based fighting game. If you’ve got a decent understanding of fighting games (Smash Bros specifically helps), you can play chess with a whole mess of moves. You can predict exactly what each move will do, as well as predict what happens for the opponents moves as well. No more failing inputs, since ever move is one click away. You get to learn high level concepts like frame advantage, oki, spacing, it’s all there with as little barrier of entry possible.
