co_dhon Nim in 2020: A Short Recap

readability <> verbosity

co_dhon Ask HN: How do I become a shell god?

Read kiss linux's source code: The kiss package manager especially.

   The web configuration bring in a hell lot of dependencies. Please make it a separate project. 
    Also if the readline part can be extracted to a separate executable, then it will be amazing. Imagine a fish like completion with psql.

co_dhon The largest unknown Bitcoin wallet moved nearly $1B for $0.48 in fees

why Chinese hacker? Discrimination.

co_dhon Goodbye, Object Oriented Programming

When will the university stop teaching OOP?

co_dhon Haskell for a New Decade [pdf]

It was google, a bad sample of programmers.

co_dhon Workman Keyboard Layout (2010)

Can't you just plug 2 keyboards, with 1 of them GMK based?

co_dhon Running Awk in parallel to process 256M records

I like the idea of using AWK for this. But you can give kdb/q a try. 250M rows is nothing for kdb, and it seemed that you can afford the license.

co_dhon Joy (Programming Language)

The point of Forth/Joy is that the language is so simple, you don't need compiler. It is a minimum language.

co_dhon Simula: A VR window manager for Linux

htop at top,my neck.

co_dhon The 2,500 year old history of why Python’s all([]) returns True

True is the unit of logic and as a monoid. You know math is useful.

co_dhon Category Theory for Programmers (2014) [pdf]

Unix pipeline a category, with text be object, and executable be morphisim converting text to text(monoid). Forth is a category, with stack as object, functions as morphisim. There are many examples. Best learn from haskell.

co_dhon Declarative Rendering Pipeline in Nim

I found that the Why Nim part is very interesting.

co_dhon Escape from System D, episode VI: freedom in sight

I hate things mostly work. Countless of hour of debugging, refactoring on the way.

A system need to be designed first, proved correct first.

co_dhon If You Can't Buy the Keyboard You Want, Build It Instead

Thank you.

co_dhon If You Can't Buy the Keyboard You Want, Build It Instead

This(pro) is what I am using now. Cheaper than ergodox ez but more beautiful.

You may need compile QMK yourself because it is flipped as compare to EZ

co_dhon Generating a Java program with 90% less code

Psql select count(email) from table where name = "foo"

What the hell happened to the world.

co_dhon Understanding What It's Like to Program in Forth (2008)

http://forth.works/examples/AddingVectors.retro.html

Here is the retro forth version of adding vector that I was talking about.

Tri@ apply function (2+x)on top 3 items. So get address of the 3rd element of c b a ..

co_dhon Understanding What It's Like to Program in Forth (2008)

That is an unfair comparison. Forth is designed to run on metal, with no os, no stdlibc, no vector. Can any of other language do that?

In fact, by just adding first class function, retro forth makes the code way easier to read.

co_dhon Buying into the Emacs Platform (2018)

kakoune

co_dhon Tokyo mechanical keyboard meetup photos

I would switch job for that. Using ergodox with colemak layout.

co_dhon Retro: A Modern, Pragmatic Forth

I don't know. It's for fun, but I believe I will have trouble to make others to use.

co_dhon Retro: A Modern, Pragmatic Forth

we are quite similar except I am paid to write q. In fact, I am writing a forth in q now.

co_dhon Retro: A Modern, Pragmatic Forth

I'd like to say thank you too. I've studied your code many times, and it helps me understand forth finally. I was attracted by colorforth first, which is harder.

co_dhon We Can Do Better Than SQL

kdb is better than sql.

co_dhon Sadly, I must say goodbye to Leaf, my programming language

The problem is, your coworker need to modify the generated code.

co_dhon Keeping a plaintext “did” file

You have only 210 bugs in 15 years?

co_dhon Keeping a plaintext “did” file

I would call it notes.txt to make it more positive. Bad code is everywhere, and don't let them make you sad.

co_dhon TerminalView – A terminal inside Sublime Text 3

Do you know Kakoune? I've used a month and like it. Fast, lean, work with other unix tools well, extend by sh,

co_dhon Vis – A vi-like editor based on Plan 9's structural regular expressions

That's why I like emacs. It has anything you can image. Due to the beauty of elisp, people have fun to write in it, and thus contributed to the ecosystem.
