Lisp is the most powerful programming language.

I swear using std::string is such a fucking pain. I swear, one of these days I'll have to make an entirely new string library

I can't use std::string anymore. Not after learning about Python, PHP, JavaScript. Pretty much any decent language

Why is std::string so bad, /g/?

>>60892935
C++ is bad.

>>60892935

>>60892949
No. C++ is the best language there is. I can't program in other languages anymore. I just don't feel right without needing a semi colon every line. I just can't not put the type of the variables.

Maybe not, but from scratch it seems far harder than a what I proposed. For example, I have realized all daemons on my machine run as their own user, and their directories are owned by this same user. I don't know if this is kernel feature, nor how such user is even created.

>>60893121
It depends on the platform and kernel.

>>60893121
Close stdin/stdout/stderr if you don't need them.
fork() and kill the parent.
Do some blocking call on some resource you're looking for. Most programs will have a poll/select loop, so it almost always happens there.

If your program just needs to go off every X minutes or whatever, then you could get away with just sleep()ing or whatever, but things like signals can cause you to wake up early.

Strings are not mutable in javascript, nor are they arrays. The index operator is for access, not for assignment. When you run your code, you are creating two new strings, "a" and "b", assigning the value of the "b" string to the "a" string, destroying both strings, and then repeating.

I'm sorry that not every language works like C anon.

It'll throw in node just the same. Strict mode is a part of the ECMAScript spec, not just a convenient put in by browsers. And node uses V8 anyway.

In your node REPL, try evaluating

(function() {'use strict';var foo='abc';foo[1]='f';})()

Tangentially related but a PSA for anyone interested, you can run C and C++ in the browser thanks to the wonders of LLVM, because a JS backend for LLVM called Emscripten exists.

Although it's really tightly integrated with clang right now. It's basically a C/C++ to JS compiler. It supports OpenGL, OpenAL, libSDL, and a lot of other stuff.

If I want to write code in that style I'll use Haskell for better actual static type verification and real purity so that I get really strong compile-time guarantees. This isn't even considering Haskell's vastly superior syntax. (For humans - it's at the other end of the spectrum. It's actually a mess to parse. Whereas Lisp is homoionic and easy to parse but a mess for humans to use.)

But most of the time I use languages I could get employed using, if only because of the existing support and libraries.

Do you usually """program""" this way?

So, Rust is faster than C, is functional and has strong typing.
It also has macros, so Lisp is also deprecated.
Why haven't you switched yet?

>>60893439
>lisp is functional
lmao
also, Haskell is useless since IO is too hard.

>>60893449
Its macros are more limited than Lisp, its type system is more limited than Haskell and it's used by many crazy liberals

>>60893439
but "purity" is a meme tho
literally nothing is "pure" about what a computer does when you take away all the abstractions and look at it for what it physically is
and thank god for that, because if you had a functionally pure processor, it legit just wouldn't do anything

purity makes it easier for you and the computer to reason about your programs
when performance doesn't matter, why should I give a shit about how the computer really works

>>60893477
Really, because I find that even though IO is meant to to be isolated, it creeps up all my code.
Once I have an IO a, I have to use a function to unpack / repack.

Also, as a challenge, make a program that given a directory, will return a list of pairs (file, filesize) from all the files under directory.

>>60892935
Try char const*.

Creating a hotloaded HTML server that uses JavaScript running in v8 as an escape language, which is cool if you like JavaScript more than PHP.

It's a C# library so you can set props, like a model in MVC, from C# which can be cached in C# or come from a server or whatever.

Kind of like

<div>you are a {{props.insult}}.</div>

Where users can run code which generates the props in c#, so you can do db stuff in C# and UI stuff in JavaScript.

That's like

ScriptedPage.get = YourFunctionHereThatRunsSomeSerialisation;

And should return JSON, which is easy for me.

And I can do that because func<string,string,string> can be arbitrarily defined. Which is cool.

>>60893467
Restricting your programming paradigm to be similar to the machine is only useful under realtime computing constraints, which Haskell wasn't designed for.

In fact, some argue that the productivity gains you can achieve with Haskell are derived from this pattern of distance from a 1:1 correspondence with the behavior of the machine.

The whole point of the compiler is to take your program specification and make it happen on the machine irrespective of the specific way the platform itself works.

Hey guys, I'm willing to make a decision tree that will classify myopia, astigmatism and hypermetropia.

I will input just the sphere and cylinder of the left and right eye:

Sphere Left Eye: -2.25
Cylinder Left Eye: -3.00

Sphere Right Eye: -2.00
Cylinder Right Eye: -3.00

So if there is a value != 0 in both sphere and cylinder of an eye, that means this person has astigmatism and myopia or hypermetropia that specific eye. If there is no sphere value that means it has myopia, and if there is not cylinder value that means the person has myopia.

And the same if there are no values at all (means the person does not need glasses).

I know how to do binary trees, but I need some red pill on general trees and how to make them decide with the numbers I will input.

I didn't claim it was "bad". I simply stated that it's a POOlang. And I don't use POOlangs for personal reasons.

>>60894432
Sounds like there was a misunderstanding then, by POO i thought you mean the indian type of abstractfactorymeme SF hipster type of language., which it's not.

Don't repeat everything /g/ says trying to be socially accepted here, study the language and rate it yourself

I have to implement a dictionary as a set in Python, where I have something like:

How can I achieve this?

>>60894462
>by POO i thought you mean the indian type of abstractfactorymeme SF hipster type of language
Anything POO (as in "OOP") is already precisely that. It's just a matter of how much worse it is than other POOlangs.
>Don't repeat everything /g/ says trying to be socially accepted here

For example

iota(5).each!writeln()

Anon it's pretty trivial. Do the dictionary lookup. Get the value, compare it to the new value, insert the new value if it's greater than the old one.

If you know how to operate a dictionary in python and if statements its trivial. If you're looking for some pythonic one liner I can't help you. I don't have severe mental issues.

>you can do OOP in it if you want to
This is true of basically any language. A POOlang is something which has POO built-in.
>ignore what /g/ says
Indeed, I should ignore POO lovers (which seem to be the majority here).

>>60894787
>>60894959
except you can't do oop in c because it does lack the semantics for the needed encapsulation of the data AND of the procedures working on that data.

>>60894999

you can emulate OOP in C by manually writing vtables

>>60894501
well that sounds not too bad. Thanks!

>>60895014
"emulate oop"? what that does even mean? you can implement an object system to be used by another PL but to have oop in C, you would need to extend its semantics and its syntax.

>what is glib
>>60894959
thats what im saying, OOP isnt the default mode for kotlin, only for interaction with Java libraries (there are plenty for kotlin though so you won tneed em)

>>60894857
Align by ||

>>60895068
The first C++ compilers transpiled to equivalent C code and then compiled as usual. The mechanics of OOP are not difficult to implement in plain C, you just lose a ton of safety since it's not checked.

>>60894511

1. step_by (note: currently experimental)
2. collect
3. loop { }

>>60894590

There is no iota in the standard library. Based on how you appear to be using it, I'd guess a function might look like this:

#![feature(inclusive_range, inclusive_range_syntax)]
#![feature(iterator_step_by, step_by, step_trait)]

use std::ops::RangeInclusive;
use std::iter::{Step, StepBy};

fn iota<T>(first: T, last: T, step: T) -> StepBy<T, RangeInclusive<T>>
where T: Step {
    (first...last).step_by(step)
}

Which currently doesn't work on godbolt.org's Rust nightly compiler because it can't decide whether or not StepBy takes one argument or two.

>>60895076
>what is glib
data type, not object. the fundamental concept of encapsulation is broken.

>>60895111
being transpiled or not is irrelevant, it's part of the implementation; what matter are the semantics and the syntax of the programming language.

the problem with C is that you have to implement the procedural interface with pointers but those pointers are also data and you have no way to encapsulate them.

You can, knowing you're looking for a period length of d - 1 for d in 1/d, and period length is always < d - 1 if d is composite. So the largest prime d < 1000 satisfying a period length of d - 1 is the answer.

>>60896223
>this is the average /g/ retard that shits on C++
Modules are there to SPEED UP compile time, by deprecating headers, you fuck. The idea is that you can just import other modules like you can do in any other language that isn't c. The reason C++ compilation takes forever is because #include does nothing except copypasting the entire contents of the included header into the source file. If you change as much as a single character in a header, you need to recompile EVERY SINGLE SOURCE FILE that includes that header, because technically you just changed those files too. On top of that modules will make writing code more productive, because there will be no more overhead when it comes to writing headers because they are no fucking headers, just sources.

This is not something easy to answer and depends on the scale of your project. For example the Linux kernel wouldn't be as big if it used a BSD-style licence since every proprietary fork wouldn't have needed to contribute back. Same goes for the LLVM project.
On the other hand small libraries can benefit much more from such a license for adoption as they don't require you to bother submitting every change back to the author.

Do you know of any Java libraries that deal with holidays?

As in, the usage would be something like:

>>60896337

Not from a development perspective, you idiot. Unless you want to increase development time by a factor of 100. Fucking hell. Why is this board so stupid? That's like saying "dude just use a turning machine, its functionally equivalent to C++"

>Does that matter? It still has all the power of C++ and C-like
Yes they do. and b are labels that are defined somewhere in the .data section and offset retrieves the address of that label as opposed to its contents.

So yes, it does matter, because obviously you don't know shit about assembly.

>>60896667
I don't believe your likely to find a library that does that. I think you'd be better off writing a java class that queries a web service like

I want to make one with a large default holiday database and the ability to add your own JSON lists.

I want the library to also be used in corporate applications, so I don't think querying an external API is the way to go. I think it needs to be standalone.

>>60896763
Why restrict it to Java however? Most of your work will be storing data anyways.

>>60896763
I think you'll find very few holiday applications don't query some kind of external API. At the very least, most have the option to update the database from some standard source, like an external API. However, including a collection of sensible defaults in the distribution is not a bad idea.
Additionally, many corporate environments are resistant to using non-XML data. Particularly in Java, XML is pretty much the standard. At the place I work in, we actually have a SQL database that we use to store company holidays, with a ASP.NET webservice to access it.

>>60896769

If you're library is to be adopted, it'll have to support the old shit. JSON is a fine format, and supporting it is good, but if you're looking to create a robust library, you have to support what the people use.

But I still don't see why a file just lying around in the project would need be in XML. Is it because the old corporate programmers are more familiar with it?

>>60897158

if (condition)
{
    doSomething()
}

Always.

>>60897158

if (condition)
  {
    doSomething();
  }

This is the only way to go

>>60897158
I mix all styles :D

do all those programming practice sites where you write algorithms have anything to do with real life problems?

Algorithms are incredibly useful, it's one of the things that separates pajeets and novice cs grads from real programmers
And be aware of algorithmic complexity, that's the basic thing

>>60897158
For single line statements

if (condition)
    doSomething();

In general

if (condition)
{
    doSomething();
}

I've managed to avoid working with VBA until now, but I don't have the authority to greenfield develop here and this is a Microsoft organization. I'm wrangling this team's project management and reporting spreadsheets into an Access database. I've started to build some of the table structure and am taking my first crack at one of the Forms whose relevant data tables are pretty much what they need to be.

I need to have the user enter in LastName, FirstName, but then reference that to an ID number. I am trying to use DLookup() or ELookup() because using straight values in a SQL query is just asking for Little Bobby Tables to show up. I don't even fucking know what is supposed to be happening here. The API is incomprehensible garbage and the documentation is worthless.

I'll figure it out by trial and error, but it feels good to bitch about it now.

Jesus fucking Christ. I can't.

I need this database system to drop into their current workflow without causing too much disruption and without causing too many waves.

This is a large organization and I am but a simple hacker.

Shit, man. Most businesses still use COBOL.

If I create a project on github or something, and I license it with some specific license.

How do I add code from other projects into my code, that doesn't share the same license? Or how do I at least credit them?

I'm thinking I should just forget about adding it into my code, and just tell people to download the library on their platform

>>60897158
Allman all the way

Where can I learn more about how to implement a "programming language" inside your program? for instance I want to allow users to use a made up language that my program will parse and do things when reading it, mainly if/else stuff

What the actual fuck are you doing?

You have two sane options: tell your team that you're going to create this software with modern tools and do so, or quit and find another company.

You can literally stand up a full SQL Server in Azure for $5 a month if you're working with a small amount of low-frequency transactions. There's quickstart templates for basic CRUD applications that will immediately Just Werk™ for what you're doing.

How do you compile C on Windows?

>>60898109
can you just use bash and gcc?

>>60898109
You can't because Windows doesn't support programming.

>>60898109
The last time I programmed C on windows I was using Visual Studio 2008 programming in C89.

>>60898135
Yes, but are you using bash and gcc through mingw? Cygwin? WSL?

>>60898164
That sounds fucking miserable. Also, doesn't MSVC not actually follow the C standard?

>>60898109
If you use Windows 10™ you can just run gcc in bash

What kind of little pissbitch are you that you'd quit a job over stupid shit like that?

I need this database application to drop into their Sharepoint easily without dealing with all of the large organization bullshit and red tape that it would take to get approval to put this data on a cloud server. It would be infinitely more of a pain in the ass to figure out whose dick I would need to suck to get approval for upgrades than it is to learn VBA. It's like you've never actually had a real job before...

>>60897707
>I make websites for a living.
>Nobody will ever trust me for anything Important™.

>>60898707
Nice try on that false accusation. I've been in situations like that before professionally, and seen many in the same situation. It's always the same story. They spend the time learning something deprecated, maybe they finish the task, then it turns out it wasn't that important and gets phased out eventually anyway. At this point, they're left with less marketable skills than otherwise possible.

I've had plenty of "real jobs", and I'm fairly certain that I'm older than you by a margin of 5+ years.

It's a fairly hard and fast rule that when Access and VBA crop up in the same sentence, something is being done horribly, horribly wrong. There's no reason why a company with your amount of "red tape" should be using something that has been relegated to ~5 employee SMB shops with Old Dave doing the IT.
