Programing Language History. the Rise of FORTRAN, ALGOL, Pascal, C, ML, Ocaml, Haskell, Rust.
One of the top 5 blogs on programing language i've read in past 5 years.
[Rust in Perspective By Linus Walleij (aka linusw). At https://people.kernel.org/linusw/rust-in-perspective ]
a short history of programing languages. Covers the rise of FORTRAN, ALGOL, Pascal, C, ML, Ocaml, Haskell, Rust.
The content is great, but the writing is also impeccable.

some major cult in the programing industry since 1995
- 1995 to 2000, java, presumed to be the last language for humanity. Just write once and runs anywhere, actually JavaScript did it. Along with the idea that OOP solves all problems on earth.
- 1995 to 2000, perl. The last scripting lang for humanity. Swiss army knife does everything. Theory is not important. Comp sci is not important. Laziness is good programer. English is best lang. Unix philosophy hack on drugs. Larry Wall did this. And big surprise , it died.
- Y2k, eXtreme Programing. A wild fire. After 10 years, it became Agile. Skum snakeoil. Math no important. Skill no important. Knowelgeable no need. Responsibility no need. Need human touch, need 2 guys sucking each other's cock and throw each other under the buss. Programing is about hugs and standup meetings. Programers r just a cogwheel.
- Briefly, around 2008. Ruby on rails. For 3 years or so. By a skum.
- Briefly, around 2008 or so, node js. The Non-blocking shit. Worst lang. Still worst.
- Briefly around 2008... Haskell, and functional programing. Omg cpu no faster, FP is future. And Haskell is god.
- Golang, julia, also born around these years. And facebook hacklang. They, never gained much cult. Golang and julia should became popular. Golang is. Julia failed. Hacklang seems never caught on.
- Because julia is related to math. The most industrial C Cpp rust types, run away from math.
- Then, today, python, rust, pop idiocy, with zoomer younglings.

programing language documentation problem. What is a reference? Java JavaScript
- here's a interesting documentation problem.
- note that, afaik, the concept of “reference” is not mentioned in js spec.
- (maybe it is. i forgot. but not in a way for programer, only to compiler writer)
- so u have this problem. How do u explain, the fact that array can be assigned to a constant and still can change.
- if u mention “reference”, then u need to explain it.
- but in order to explain “reference”, you have to mention implementation and hardware, such as memory address.
- but these things, are irrelevant to JS the language.
- The solution, seems to be, to add a concept of “reference” to the language, by saying it's just some kinda object ID. Python does this with object ID, and Java does this with an actual value type, the Reference Type.

perl in WolframLang style
supreme. Delete Duplicate Image Files
Perl in wolframlang style. Year 2003. Notable are the functions: combo, reduce, merge, genpair. (not what you think) and using nested list the way you'll not find in industrial code.
Lol, look at this one liner Mathematica style
- used to piss the perlers, and plus, they no understand it.
- overly complex. even i no unstand it now. lol
- not complex in a dumb way. but complex in the sense it follows a 'elegant' and very functional programing and using nested list extensively.
- and follows a strange one-liner style.
Been using dark theme for 5 months now. Conclusion: light theme is actually easier on the eye.
But one particular interesting thing is, bold word are less perceptible when its white text on black. Example: Code where variables are bold, when in dark theme, it's hard to tell if they are bold at all. Similar for for headings with larger font size, such as html h2, h3 headings.
