We have this weird homebrewn DSL for our test environment. It would be "fine" if it wasn't for the fact that it doesn't have stuff like functions. Instead you have to execute other scripts and pass all parameters as globals. Oh and of course all scripts modifies other globals so you have no idea what's going on

on the subject of weird pointless heap allocations you can create in .NET without noticing, i have recently learnt that in F#code:code:https://dotnetfiddle.net/QkEJiM -> choose "view IL" in the menu at the top right basically the answer to 90% of questions about f# and performance seems to be "inline that poo poo"

in f# if your let/use binding has no parameters it will make a thing and if it has parameters it will define a function. it's a pretty straightforward rule.

tef posted:c++ users they're like the lisp users of systems programming no matter what you do, it could always be done faster in C++ any sufficiently complicated abstraction could be made easy by using an esoteric feature of the language out of common usage that sort of person who tries to win arguments with the entirety of the language at their fingertips but unwilling to concede that production use requires subsetting such a beast of a language. you can tell c++ has the lisp problem because heavy users come down with a bad case of making a new programming language that's just a little bit different sure, it is limiting to bring in constraints and work in a less powerful language but with constraints come focus many people think the measure of strength of a language is the lack of barriers, or a pay-as-you-go mentality for features. after living with the wreckage of this mentality, i think language designers have a responsibility to limit and not empower programmers, there are enough reckless languages already. i mean pay-as-you-go works out in your favor when you don't use a feature, but when 90% of you code does maybe that whole "no-gc" thing doesn't work out a programming language is kinda an executable manifesto on how the author believes you should be programming, and when you don't limit it in scope you punt that decision to the developers and this is how you end up with 60 page coding conventions on how to write acceptable C++

echinopsis posted:so ue4 uses c++.. is it appropriate there? probably, because there isn't a great option for gamedev because performance is the most user-facing feature i mean i'm not saying responsiveness isn't important but i've found that is a bit more architectural than a always down to language choice alone. but a whole bunch of gamedev stuff is done in c# or even javascript atop (like unity). going down to a language like C++ is fine, and often the entirety of a project means that it is reasonable to write at that level of control and responsibility but in the end poo poo gets glued together to make stuff happen, so the idea that instead of "let's write our own special dsl to let people avoid coding" is bad but the idea of "well, let's do the heavy lifting in c++ and punt out to lua, c#, js" is very, very good

It's a very popular language in the physics community (probably second to python) and I've never met anyone who uses it out of a machismo thing. A lot of people legitimately do need the speed (especially simulation writers), and there are a lot of physics libraries written in it (most notably ROOT for particle physics). Also everyone's advisors know it, so you can ask them coding questions whereas if you use something like Java you are on your own. (Also lol at using Windows in physics academia, so the entirely of the .NET languages are no-gos from the start.)

i'm reading about vector graphics since i'm doing wireframe polygon stuff and lolquote:There are several methods for producing the clock rates we need. Atari used Binary Rate Multipliers (BRMs). A BRM is a counter that divides the input clock by a digital number. Although the pulses it produces are not guaranteed to be evenly distributed through the counting cycle they will be close enough for our purpose.
