Trying to understand complex social systems was my favorite timepass. I went through Eastern philosophy and religions. algorithmic trading, Informix system administration and functional programming. of course. I am a FreeBSD and Gentoo addict too. I almost always compile my stuff from sources (so I know all the dependencies by heart). In particular, Eastern Philosophy (the Early Upanishads and Early Buddhism) helped me to sort out what the current AI tools can achieve and what they cannot do in principle (and I showed why)....

You probably have already read things like “Async computations form a Monad” or something like that. Did you ever ask yourself why would they? Here are the answers for you. Have you ever seen that kind of device in some chemical and physics labs – a glass wall, with two holes in it which have a pair of thick gloves attached to them, to reach inside? A person put his hands into these gloves and reach into a contained and sealed compartment (environment) and is able to perform some tasks, like moving and filling things inside....

Once one has been exposed to a wrong concepts or just bullshit it is very difficult to unlearn what is “already known” and to see things as they really are. Especially when a necessary abstraction barrier is neglected or not even well-understood and some implementation aspects are mixed arbitrary with definitions of an abstraction itself, and with parts of a supposedly abstract interface, which has to form (establish) the abstraction barrier....

Lets talk about something really hard. There are at least 3 whole asynchronous, concurrent “full stacks” on top of the Java Runtime written in Scala (which compiles to the JVM bytecode and its standard library is a wrapper around Java’s). The first one, arguably the most widely used. is the Twitter’s platform. Then comes Lightbend (formerly Typesafe), and then stack upon which Spark has been built. The most amazing thing is that vastly complex codebases, like Twitter “it just works”....

The great programmers of the past, who wrote the fortran numeric libraries, lets say, drew flow-charts for every procedure they are about to write. This gave them the right intuitions and the right feeling about what they do. At the level of expressions you have just (only) recuring 3 patterns - it will be either a sequence, a conditional (branching) or a loop (recursion), so when they begin to write the code, they were never confused – it has to be one of these....

There are already several websites which publish a “roadmap” of how to teach yourself programming (University keve) using freely available courses and textbooks. Here is my 2 cents. First of all, SICP is an advanced textbook. It is by no means suited for teaching freshmans, unless you are a MIT student, who is math-lover and a “slow thinker”. Brian Harvey, the great, managed to teach the CS61A at Berkeley – a SICP-based course which goes at a slow pace....

Some hard problems will never be solved by “brainstorms” (more like bullshit-storms) or any about of babbling by Chuds. They require the trained minds like of C.A.R. Hoare or Leslie Lamport. or Philip Wadler or Martin Odersky – the outliers and top performers.. Ideally, they have to be mathematically mature, and preferably on the compiler side (so they also understand important implementation aspects). The “direction” is actually clear and well-understood (a small miracle), and it is in restricting too general concepts and formalisms with additional constraints (so they actually match the environmental constraints), or just typing....

Lets talk about some targets no one else sees. I am a prod student of Brian Harvey, the great. I used to watch his CS61A recordings like other people watch stupid TV serials. For me it was something like watching X-Files or Twin-Peaks, which are only non-stupid ones. The problem was, however, that even if I understand every word and almost every concept mentioned, I didn’t know which are the most fundamental ones and which are just accidental notions or just preserved in a shared culture social constructions....

Google deprecated external access to its IMAP due to “security reasons” Karpathy posted a classy coding video lecture in which programming has been done entirely from the default Mac OS browser (doing everything in a web-interface to a Jupiter notebook). Corporations want us to stay in their (and only their) browsers all the time (in many different tabs) and never leave, so they can collect all the data they want....

What could even be in common between Haskell and Rust? Well, they are the most advanced languages of its time, the most controversial and the most discussed. Most importantly - both languages are have a proper type-classes/traits based standard libraries, where the type-classes/traits define major modern mathematical notions, which can be traced to the modern set-theoretic math and related notions. This is what makes the actual difference with other crap like PHP....
