   I'm glad to see that people are willing go even longer distances than me for a practical joke. Unrelated, but this must be the only wikipedia page I know of that contains a joke.

   I haven't thought about it. But something I would like is to participate more on HN. Also find communities around me with similar programming interests and be more active there. So there you go! Happy 2023 everyone

   For some people watching too much porn damages their actual sexual life. Granted in other cases might help. So it comes down to a personal choice. Some people don't want to support the darker side of the industry. They don't know&

   This is a great library! Also another amazing piece of software behind quickjs: https://bellard.org/libbf/

   Thanks! Will definitely check them out too!

   Oh wow! Great resource. I think it strikes the right balance between lexing/parsing vs code generation/optimization. I see that not even in modern books things like PEG parser or Pratt parsing make the cut. Which is a pity IMHO. A

   This is great! Can't wait to try it out as soon as I am on a computer. I will see if I can hook this up in my little side project: https://github.com/nhatcher/ariana-lua

   Thanks! I don't think I have ever seen mathsteps. Looks like a great tool. I will have a look at it!.

    The desmos calculator is great! And very much in line with what I would want to do. Maybe it's just me being shy to approach someone on the project or the stupid "I want to do it myself" but I haven't tried to join any e

    I would like to build a small CAS (Computer Algebra System) that is usable from the web. It could be used in education to plot functions, solve equations (algebraic, ODEs, PDEs, ..), work with matrices, complex numbers, number theory, you n

    Get into a university club. I got into spelunking and almost instantly got friends. I was more of a trekking kind, but learned I also liked caving and got some long lasting friendships. Good luck!

    I have been using Caddy for quite some time now, as a replacement for "python -m SimpleHTPServer" and by just flipping a switch as real webserver and this is such great news. I am so happy you end up going down the route of an ope

    After working for almost 7 years for the same company, I had a meltdown for many different reasons a bit more than two years ago. I have a fairly nice job and work with fantastic people. But plainly speaking I was getting tremendously bored

    Yes, but m is zero anyway.

    No, there is only one unknot and only one 3_1 knot, for example. Am embedding is not a knot, the knot is the embedding + the equivalence relation. So, just the embedding would be a presentation of the knot.

    Oh! shit, I misunderstood your proposal completely. That is definitely not the goal of Algebraic Topology... Sorry about that. If you say two knots are equivalent, in mathematics, that means they are equal, one and the same. You can't

    Because we can't find them :S. In the case of knots, we would rather have polynomials associated with knots that satisfy your requirement. But we just don't know how to do that. It is the same with topological spaces and homotopy

    That is extremely difficult but that is, indeed, the goal. The main business of algebraic topology is doing exactly that.

    It is not a make-believe diagram. It is a completely valid diagram, but it i just part of something bigger. Also the two quarks in the diagram need to ultimately couple to something else. The "in" and "out" final states

    That's just a part of a bigger diagram. Due to color confinement you can't just have one gluon.

    I also learned the big-oh notation there. Among many, many other things. Absolutely great book.
