I believe, it was pro-military, but not pro-war. The book idealizes the state and social system, and uses war only as a backdrop.

funny_falcon | 1 year ago | on: The Pentium contains a complicated circuit to multiply by three

Compilers still prefer LEA to multiply on 3,5 and 9, which performs shift+add I believe.

funny_falcon | 1 year ago | on: From C++ to Clojure: Jank language promises best of both

First SmallTalk versions were built with Lisp. “Live environment” and “world image” were just inherited.

And looks like Helix editor uses it together with ropey.

funny_falcon | 1 year ago | on: C: Simple Defer, Ready to Use

OMG!

returns_struct looks actually correct to me, ie it is expected (by me). Golang's defer works this way.

Do both examples follow standard? Or is it common misinterpretation by all compilers?

Do you use stanza?

funny_falcon | 1 year ago | on: C++ is an absolute blast

There is the trick: use enum for const. It works most of the time.

It seems meson is gaining traction and will overpass cmake in near future.

funny_falcon | 1 year ago | on: Float Self-Tagging

Another quite similar technique from OpenSmalltalk: https://clementbera.wordpress.com/2018/11/09/64-bits-immedia...

In fact, CRuby successfully combined “Self Tagging” with pointer tagging. Here's the commit:

I mean, CRuby does “Float Self Tagging” for years. Paper just has the mistake about CRuby.

funny_falcon | 1 year ago | on: Float Self-Tagging

CRuby uses this technique on 64bit platforms for years.

Edit: the commit https://github.com/ruby/ruby/commit/b3b5e626ad69bf22be3228f8...

Just correction: CRuby uses “Float Self-Tagging” for years.

funny_falcon | 1 year ago | on: A high-performance, zero-overhead, extensible Python compiler using LLVM

Readability, reproducibility, and simple LRU.

Reproducibility matters for tests, they become simpler. Some other algorithms become simpler as well.

LRU is just a dict with preserving order: on access just delete and insert again.

Unfortunately, pocketpy moved to global reference to vm recently while changing implementation from C++ to C. Weird decision.

AFAIK, Signal doesn’t provide any way to prove its application were built from non-modified audited free open source code. Indeed there are evidences it behaves “a bit” differently.

So unless you’ve built application by yourself, you have no guarantee of it’s sequrity.

What “Statically typed” would mean for SQL DB with extensible type system?

funny_falcon | 1 year ago | on: Show HN: High-precision date/time in SQLite

As a PostgreSQL smallish contributor I just can say: NO, DON'T DO THIS!!!!

Extensible type system is a worst thing that could happend with database end-user performance. Then one may not short-cut no single thing in query parsing and optimization: you must check type of any single operand, find correct operator implemenation, find correct index operator family/class and many more all through querying system catalog. And input/output of values are also goes through the functions, stored in system catalog. You may not even answer to "select 1" without consulting with system catalog.

There should be sane set of builtin types + struct/json like way of composition. That is like most DBs do except PostgreSQL. And I strongly believe it is right way.

First three are clearly documented in language reference, which could be read in several hours (at least before generics were introduced).
