contrarian notes on software engineering, Open Source hacking, cryptocurrencies etc.

If you copy&paste, or even accidental reuse a copyrighted code or other materials in your personal project, and a Big Co. finds out they're going to sue you and/or take down your project.

If Github/Microsoft scraps all of GPLed code they can find and feeds it into a database and obfuscates it calling it “an AI”, then start selling it for money, apparently it's supposed to be a “fair use”.


I don't have any other place to beg. Will edit after a successful registration, so if you still see it, I'm still patiently waiting.

My mail is at the bottom. Thanks!

Thank you!

In one of post on the excellent blog of Ted Kaminski he talks about Data vs Object distinction. When I was reading it I got excited because I've been mulling about this exact distinction when crystalizing my problems with mainstream-class-oriented-OOP. And I think we're both aiming at the same thing, but I have drawn the line between the two differently. Plus I have some other thing to say about this confusion.


From my point of view, the main source of progress in programming (software engineering) was, is and will be sacrificing small scope expressiveness and power to improve larger-scope composability.



It's very good, and I pretty much agree with everything in there.

For an Nth time, I'm seeing the story of the smartest woman in the world proving everyone wrong on the Monty Hall Problem. You probably want to make sure you read it before reading further.

I've never seen anyone mentioned an argument that is pretty obvious to me, and invalidates the whole “logical” and “mathematical” conclusion, and proves that people's intuition is correct.


I keep thinking about this idea of a different approach to building Operating Systems. I know it's not a new idea.

I guess the core of the idea is that the programming language, its runtime, and the OS should be the same thing. You know – kind of like Emacs or generally Lisp, or Smalltalk. Where the language is the runtime, and it allows modifying itself while its running.

Maybe I'm wrong, and what do I know about anything anyway, but I think the previous attempts to make this a reality were outcompeted due to practical considerations: mostly performance and resource utilization.

You see, I am a bottom-up developer.: When I was a kid I first learned how do electric switches and transistors work, how to chain them into longer logical circuits. I was playing with writing assembler code for MOS CPU of my C64, POKEing and PEEKing bytes into addresses of memory mapped hardware registers. As a teenager, I was hacking on a Linux kernel. For me, the computer will always be only a very fast automaton, composed of circuits, capacitors, and so on, executing long sequences of tiny CPU instructions, and the job of software is to make it do something reliably and efficiently.


Putting an “innocent” tracking links and “pixels” in your email is like taking photos of people without asking or even putting a security camera in your guest's bathroom. Just because most people won't notice or complain and you pinky promise not to use it for anything nefarious doesn't make it less rude.

Pretty much everyone are doing it now. Almost all companies, recruiters, salespeople, even official US government emails. Since I use NextDNS and block most tracking on DNS level, I am acutely aware that I can't just click any link from an email without hitting a blocked tracking page.

And if you're doing it, then I think you, your company or your institution are rude.

The new era is beginning, and the old era is ending. C and C++ as a lingua franca of systems programming are being displaced by Rust. Many will deny it, many will fight it. But I'm confident it is already happening and is inevitable to continue at accelerating pace.


As some people might now I am a vocal OOP critic. I think it is fair to say that I am on a crusade, actually. :D

Oftentimes, my long online posts explaining what is wrong with OOP meet with a No true Scotsman argument. That I am somehow pointing out to flaws in caricature of an OOP, and the correct OOP is free from these issues. To prove to myself and other people that it is not the case, I decided to go through some classic OOP books, and criticize the OOP examples in them.

My first choice is the Clean Architecture by Robert C. Martin (aka Uncle Bob). I must admit Uncle Bob is not one of my favorite software engineering gurus. But he is a reputable and experience developer, and if he was to write a caricature of OOP, then who are the people who dare to say they do it right?
