Qt signal is ten times slower than a virtual function

Is XMPP any good? Also, let's write a client in Tcl, maybe
I still have my Nokia 5800 lying around. It runs Symbian. That platform is quite different from Android. For one thing the internal storage size is 81 MB - less than what your single android app takes up, even in RAM, and it works faster than modern smartphones - e.g. the SMS app opens instantaneously. Another…

My lazy Wordle strategy: same words every time

New integer types I’d like to see
(Most) C++ implementations provide at least 8, 16, 32, and 64-bit signed and unsigned integer types. There are annoying implicit conversions, discussions about undefined behavior on overflow (some think it’s too much UB, others think it’s not enough), but for the most part they do the job well. Newer languages like…

A friend of mine recently brought up his custom mechanical keyboard while we were hanging out in voice chat, and at first, nobody understood why anyone would buy one. At that time, I had no clue that there are entire communities about building custom keyboards. With every sentence that was said, we got deeper into…

Exercises for understanding Haskell Lenses (2019)
No matter how many blog posts and tutorials I read about lenses, it seems like there's no replacement for just using them to get an intuition. So here are some exercises I came up with. While they shouldn't be all that difficult, they build up from some basic knowledge about lenses up to the more advanced usages of…

The examples in the textbooks are not representative of real world problems
Bill Harris points to this cartoon from Randall Munroe. I think he (Munroe) is really on to something here. Not about Bayes’s theorem but about the sorts of examples that are in textbooks.

Update on the fake story about the river laborers paying people to whip them
As you might remember from a few months ago , there was a story going around that some economists just looooved to tell. The story had all sorts of attributes that you might expect would make economists happy , including a paradox in which apparently bad behavior (whipping people to get them to work harder) was…

Generating true random numbers from bananas
It was a dreary afternoon in Milan last year when, procrastinating on studying, I was struck by a flash of genius. “What would happen if I made a banana-powered random number generator?“. I immediately went to tell my roommate, who was also an electronic engineer.He looked me in the face and burst out laughing. At ……
