Have a look at the Tiny Go compiler, which does more optimizations: https://tinygo.org/docs/concepts/faq/what-is-tinygo/ As mentioned you can also bypass the GC for performance critical sections.

Go is fully native unlike VM-based languages. It stands half way between C/C++/Rust and Java/C#. Also, for performance critical sections, you can bypass the GC by importing "C" and "Unsafe" to get manual m

Yes, considering this program ran from April 1947, it can almost be considered computer archeology. I find it fascinating they already came up with labels and functions. The ENIAC is a fascinating machine as well, from its initial modular,

For those interested, the first Monte Carlo program, which ran on the ENIAC, has been found and documented (840 instructions long). It was also the first stored program ever run. https://eniacinaction.com/the-articles/3

Mystery and craftsmanship. It's the same feeling as restoring an old car and being captivated with some very simple, ingenious and alien mechanics. Same with computers, the older it gets the more interesting it becomes, down to deciphe

import "C" import "Unsafe" is all you need for manual memory management and pointer arithmetic with Go. Since the GC is fairly light and snappy, I find it's best of both world to only resort to Unsafe for

It's not a native desktop app either, it embeds a large JIT and a hello world is around 50 MB.

OP insisted on _native_ desktop apps, not wrapped web apps. Otherwise Java/Swing would have been a no-brainer.

What's wrong with Object Pascal? "Plain" Pascal is about as efficient as C, uses slightly less memory, is safer because of its lower dependency on pointers, and is easy to work with, especially with strings. Then Object Pasca

Page 50: "A compromise between assemblers and high-level languages, C helps programmers avoid the idiosyncrasies of particular machines". Interesting. I thought C appeared as a (very) high level language back in 1983, when develop

Likewise. Go was engineered for simplicity mostly in reaction to the complexity of C++. As anticipated, now that we got generics, some developers keep asking for more and more features. Let's not turn Go into another C++ when its goal

Go was created for correctness. It is strongly, statically typed, it won't compile if there are unused imports or variables, and it won't compile either if you don't free up resources after usage. C/C++ don't do tha

> Python/Go I wouldn't put those two languages in the same class. Go has about the performance of Java/C# with about the memory usage of C++. It's much closer in performance and resource efficiency to those languages

So a young developer inexperienced with COBOL and old computers tries to set up his modern days IDE for it, "laughed hard" (sic) judging it by modern standards, then publishes a long article to share his misconceptions. Honestly,

Cygwin is extremely lightweight, it's basically just a library implementing the POSIX syscalls, and native win32 apps linked to it. Since it's so lightweight, you can have, use, and throw away as many cygwin envs (folders) as you

Ditto. Unions are just another lobby. They seek subsides, money, and power. Unions, like companies and governments, exist mostly for themselves. That doesn't mean they don't mean well (sometimes), but trusting them shows a bit of

This works differently on a stack CPU but it can also be done. https://en.wikipedia.org/wiki/Stack_machine#Out-of-order_exe...

When Burroughs started experimenting with stack processors in their B5000 computer, they didn't do it for code size but the ability to use high level languages first, going as far as to hide assembly language to the user. Compilers are

It seems common all across Europe, maybe the whole western world. Here for France: https://www.60millions-mag.com/tests-comparatifs (I just laughed as I see they even review fries brands, and sex toys...)

Which is why industrialized countries with higher population density move back even faster to pre-WWII urban planning (EU), or sometimes never left it (Japan).

I keep a bad memory of how slow XP, 2000 and even NT4 were on late 90s machines. Windows 9x was a strange beast, being a VM running on top of a DOS hypervisor, but it was mostly C and inline assembly and felt fast, even with 8MB of memory a

Writing for the top performers is the main reason why computers turn into e-waste. It's Wirth law applied. I wish more developers would work on RPIs for the same reason.
