I have several ideas for some cool browser extensions/addons that could make a radical difference in how people interact on the web, so much so that I'm ready to dedicate the rest of my life to realize this one idea, I think it could create a new Internet golden age.

at this point, I have only knowledge of HTML/CSS and recently started learning python.
Ultimately what I want to make is a fork of Firefox with all the extensions I've imagined built-in. some of which would make some pretty fundamental changes to the basics of the browser itself.

Can I get a road map of what to learn to so that I can make this? like what programming languages? but also anything else that might be useful.

I imagine that if I where to publish my ideas that almost immediacy there'd be people who would develop it. but I want to make sure that it will be open source and also released with all the features fully ready at the same time at launch, otherwise id fear of simply having ideas ripped off and poorly implemented in other browsers, or worse yet in an incomplete form, even tho each idea fairly different, they all come together to create the full experience. if the browser can be released in its full form from the beginning though, I believe it would have the greatest chance of wide adoption.

for the above reasons, I want to start out by making it alone and only after the visions fairly concrete invite others on board to help build it.

so again what should I learn? Thank you Alice.

C++ thread

Everything C++: What you like/dislike about it, what you'd like to improve. Of course, also post your C++ projects.

I really like C++ because it is powerful, yet allows very intricate control over what the machine does. I think that efficiency and adaptability are the most important features of code, aside from cleanliness. What I don't like about it is that the syntax is not parsable by push down automata (so it's not context-free).

Presenting:
libcr
, a coroutine library I have written in C++.
https://github.com/sm2coin/libcr
It achieves true M:N threading, and I spent a lot of time on the atomics to try to make the scheduling as efficient as possible.
I benchmarked it, and its context switching and scheduling is faster than Rust's and Golang's coroutines (>1.5x) / goroutines (>20x @ 12 cores), so I am quite proud of it. Because of efficiency reasons, coroutines do not have their own stacks, so scoping variables and native exceptions are not supported. But the syntax ended up being nice enough to not be a nuisance, I think (see the docs/intro.md).

Let's all love Lain!

C Thread

Reasons to learn C

C has a significant amount of software written in it, including the Linux kernel. Learn C if you ever want to hack on the kernel, any UNIX-based operating system, device drivers, or other embedded / firmware / device-level software.

It has two major compilers (gcc and clang), with gcc being the oldest and most popular and clang being younger but built on a better technical foundation. This is in addition to a high volume of static and dynamic analysis tools. Learn C if you like languages with lots of tool support available.

C is very good for writing simple single-threaded programs that go fast with low memory overhead. Learn and use C when you want more explicit control over your program's memory usage and the operations it performs, e.g., for implementing searching and sorting algorithms.

Learn C if you ever want to do any kind of reverse engineering or executable binary analysis. It's likely the thing you'll be analyzing will have been written in C or something similar.

Learn C if you want to get a good software engineering job. There are lots of opportunities for both maintaining old C code and writing new C code.

Things that aren't reasons to learn C

Plenty of people might disagree with me on these, but I feel like there's a lot of misconceptions about what C is good for and what it isn't good for. Here's some things that it's not so great for.

Don't learn C for writing performant programs. Earlier I mentioned that C is good for writing simple programs with low memory overhead and great single-threaded performance. Anything more complex than this starts to get nontrivial very fast. This is because C has generally poor and difficult to use concurrency tools (complicated multithreading, synchronization, and atomic primitives that take a lot of effort to use correctly).

Don't learn C for writing anything complex that also needs to be correct. Proving the correctness of a C program is more or less impossible without first writing it in a second, more formal language. C is also full of undefined behavior, which is pretty easy to avoid, but you have to know what to look out for.

Don't learn C if your real goal is to learn C++. Just learn C++ in that case. C and C++ are different languages with very different best practices.

Don't learn C to make it easier to learn other languages later. IMO it's better to start with a functional language like a LISP or haskell than a procedural language like C.

Other things to watch out for

C has no garabge collection, which can be a good thing or a bad thing, depending on your needs. Be careful about putting things on the heap with functions like malloc, since you are responsible for freeing that memory!

C has a very limited understanding of bits, which can actually make it somewhat difficult to write device-level or networking programs where each bit is important. Use bitfields with care.

Compared to other languages, C has a very empty standard library. Any datastructure more complicated than a character array you'll likely end up implementing yourself.

How to learn C

http://www.iso-9899.info/wiki/Main_Page is the best starting point for finding resources for learning C. It will tell you what's good and what's not good. It's maintained by the fine folks on the ##c freenode IRC channel, which is also full of very knowledgable people. They take C very seriously.

/racket/ thread

Racket is a general purpose programming language descendent of Scheme. Its key features are its powerful hygenic macros, simple module system, and contract-based type system. Racket's designers describe it as "A Programmable Programming Language", with the aim of allowing programmers to easily create and interop DSL's. The way Racket achieves this is primarily through the "#lang" option, which treats libraries as languages, and allows syntax and semantics to be imported, borrowed, extended or completely rewritten.

Racket is prominent in introductory teaching of Computer Science, in courses based around the book How to Design Programs. HtDP takes advantage of Racket's DSL capabilities by providing the student with subsets of the language which gradually introduce more features as they become more experienced with programming.

This doesn't mean that Racket is restricted to teaching. Racket shares many features with other popular languages, and more. Racket has list comprehensions, pattern matching, object orientation, a C FFI, a statically typed variant (Typed Racket), threading primitives, and more. Racket can be thought of as a "batteries included" Scheme, and is a breeding ground for experimental language design.

Have you ever used Racket? What do you like about it? What don't you like about it?

Is it just me or are recently published programming books a complete waste of time? I am disappointed every time I try one. Usually they are much longer than their content would make necessary, the examples (if there are any) are inane, the exercises nonexistent or so basic they can be solved by common sense without touching the book, the only useful content they have are duplicated from the freely available manuals and documentation… Yet their reviews are nothing but praise, the ratings always very close to the best possible. There's so many of them it's almost like they are mass produced, and they all seem to be bad. Who will remember any of these in ten years? Or even just five?

Project Euler

I saw Project Euler mentioned somewhere in a thread, and after visiting the site, I decided to try to learn programming by going through it. Sadly, this newfound resolve was short-lived because I couldn't get past the first problem:

>If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of >these multiples is 23.

>Find the sum of all the multiples of 3 or 5 below 1000

I used batch to make the program, and it outputs the right answer when I set the multiple limit to under 10, but it won't work for multiples below 1000. I have no idea what I'm doing wrong.
Here's the script:

@echo off
REM Initial Variables

As far as I know, there's no general html/css thread. I know they're not really programming languages, but I didn't know what place would be better for this thread. I've been thinking about getting into web-development for my own gratification. What i'm woried about is that any modern guide to these things might teach me how to create something I hate: most web 2.0 design.

Recently I looked at this article about what to avoid in web design, and ironically enough, the site it was on had elements that I found stupid and unnecessary.
https://www.mockplus.com/blog/post/bad-web-design
Pointlss drop-down menu that opens up a pop-up, distacting social media plugs that follow you as you scroll down, plus even more crap that takes up the bottom the windows and reduces available screen real-estate for the information I came for. The list itself seemed mostly sound except number 7, which made no sense and presented a horrible positive counter-example.

To me, good design in anything prioritizes function over form. The only bells and whistles a site should have is a banner, color scheme, and font. The more unnecessary crap that's put in that also makes things slower, the worse. Seems like the internet has diverged from basic design principles. Where can I find a guide that prioritizes the same things as me?

Welcome all, to the /lambda/ FP general! This thread serves as both a discussion of more abstract concepts of Functional design as well as a place to discuss/collaborate/bitch about specific FP languages and projects.

In brief,

In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data.

JavaScript Discussion

Right now my favorite language is javascript. I know and have used several other languages in the past, especially python, but I've decided that I see no reason to use anything but javascript nowdays, unless I need a certain tool for a specific job. Why? It turns out it's really comfortable to use, it makes sense, can look good if you format it nicely, it evolves quickly and smartly every year, it's everywhere: Web Applications, Desktop Applications, Mobile Applications, even on Embedded Devices (something I'm interested to try one day). I still have to catch up periodically because it's actually a pretty rich language, which ironically evolved from what appears to have been a quick hack. Right now it's still seen as a meme language by some, I personally fear Node, NPM and the ecosystem in general might not be as mature as they could be, but it works now and hopefully it evolves in an intelligent and safe way.

C64 and similar 8-bit CPU based Microcomputers

I've recently taken to refreshing myself on 6502 assembly in order to write software for the C64. Initially I was torn between choosing learning assembly for the Gameboy and the C64, but I figured development would be more satisfying on the C64 since I would be able to see results on the physical hardware without much hassle. There are also some features of the 6502's instruction set that I like over the Gameboy's CPU such as the index registers being very helpful with working on larger amounts of data and not being restricted to perform comparisons exclusively on the accumulator. I believe the zero page is larger on the C64 as well as not being forced to transfer and execute a subroutine in the zero page just in order to update sprite RAM.

Anyways, if there are any of you that have experience with writing assembly for 8-bit platforms I would love to hear about your experiences with it.

For those who would be interested in learning assembly for an 8-bit platform here are some resources for learning how to do so:
6502 assembly crash course - https://skilldrick.github.io/easy6502/
C64 specific tutorial - https://github.com/petriw/Commodore64Programming
Links to various GB assembly tutorials - http://www.chrisantonellis.com/gameboy/
Platform agnostic tutorial for Z80 assembly - http://www.chibiakumas.com/z80/multiplatform.php

If you want to learn how to program for one of these platforms but you think you can't for whatever reason, it really isn't much harder than writing C. It's probably more tedious than anything, but certainly not difficult to wrap your head around.

Learning C# at the moment. Can't say I hate it too much,,,
short x = 2;short y = 2;// short z = x + y;         -- won't compileshort z = (short) x + y // correct

This makes me laugh though. While x and y are both shorts, the result of their addition at runtime will implicitly be given the type int, and so requires an explicit cast to be assigned to another short. I understand nobody really needs to be working with shorts in C#, and if memory efficiency at that level is something you're worried about, then the bloat from the C# runtime will eat up way more memory that you'll be "saving" by using shorts instead of a 32bit or 64bit number. Still though, this makes me chuckle.

Can't say I dislike the language itself so far honestly; though I prefer a lower level language. While easy to learn and work with, it's no fun at all. The biggest drawback for me being that it's primarily a language used on windows. Who the fuck wants to use, develop for, or (god forbid) develop on windows?

Anyone else have thoughts / opinions / horror stories or just quirky anecdotes relating to C#?

Also if you have or know any good stories about debugging, I'd love to hear them!

Introductory Resources (Computer Science)

A lot of "beginner" threads in programming boards aren't very academic and aren't really directed towards actual beginners. They almost never share resources for someone who has literally never typed a single line of code in their entire life. The following two textbooks and courses may be especially challenging for the person I've just described, but they actually start at the beginning and introduce one to programming in a rigorous manner that endows one with a conceptual understanding of the science of computation and how to think computationally rather than only how to engage in programming itself.

THE HARM OF FOSS ZEALOTRY

When people install any piece of software, proprietary or otherwise, they are doing so because they expect some utility from it. It adds something of value to their life. When you tell people to uninstall that same software, you are asking them to voluntarily remove that value from their life, often without an adequate replacement, whether you think so or not. There is no open source Adobe Photoshop. There is no open source Discord. There is no open source World of Warcraft.

"Yeah, but [insert software here]." If that software were what someone wanted, they would have probably installed it already. It isn't. Even if you don't understand or respect why. When someone resists your overtures to remove or replace the software you vehemently dislike, it is happening for a reason. Maybe they need it for their job. Maybe they want to talk to their friends. Maybe they just want to enjoy life.

Telling people they are wrong for wanting these things leaves a bad impression of the FOSS community at large and alienates people that might have otherwise been persuaded. Instead of chastising someone, try educating them instead. Maybe they will be converted. Maybe they won't. But policing what people do with their computers is the absolute antithesis of what the "free software" movement should stand for.

Every line of disparagement against a piece of closed source software could have been a line of code building an open source alternative.

Stop bitching and start coding.

>June 2017 was the first month that Python was the most visited tag on Stack Overflow within high-income nations. This included being the most visited tag within the US and the UK, and in the top 2 in almost all other high income nations (next to either Java or JavaScript). This is especially impressive because in 2012, it was less visited than any of the other 5 languages, and has grown by 2.5-fold in that time.

elixir on the web

so have somewhat fallen for the elixir hype. written my way through 50-or-so
problems on exercism, project euler, et al. and think i'm in love.

the problem, though, is somehow moving past that and onto "real-world
applications". i'd really like to swap out the guts of my small personal
website, which currently runs on an awful mess of php generating script-less
html, to use elixir as a backend.

so the requirement, then is "respond to ssl-encrypted http requests by spitting
out generated html", with no worrying about scripts or databases or anything
else. what's the simplest way to go about this? most things seem to point at
Phoenix, but it looks to be some kind of giant stack, and it's introductory
guides all seem geared towards people who've used other "web frameworks"
before, which foreign terminology littered throughout.

Test-Driven-Learning?

I had this idea and I wonder what do you think about it.

There are these kind of exercises where you are given a program and optionally some kind of input and you have to answer what the result is or what is written out. I've mostly seen them used in exams but I had a course on logic programming with Prolog that had a website where you would get tons of random exercises like these, some just for unification, some for the whole evaluation. I did all of them and it really helped me form a mental model of how it actually works.

I think forming a model of how evaluation works is something a lot of beginner programmers struggle with, but I've never seen anything like this used to train them to think about it.

My idea was that you could copy the test-driven development approach to make an effective training program like this. Basically, you would assume that the student has the simplest mental model that could correctly answer all the previous exercises, give them an exercise that cannot be solved with it yet, and force them to correct their model. In practice every new feature would probably need multiple exercises, the actual amount possibly based on the student's speed of solving the exercise or maybe some self-reported difficulty metric. Of course this wouldn't replace the current teaching methods, but I think could be a good additional tool to somewhat quickly develop a good intuition of the target language.

What do you think? Is this really stupid or something that could work?

programming typography

While I enjoy using

as a general purpose monospace typeface, while coding I much prefer to use

Fira Mono
font. I personally use the 'light' weight in my editor.

https://github.com/tonsky/FiraCode

Mozilla really did an incredible job creating a type with such elegant form and effective function. The 'i' and 'j' and 'l' are even more distinct than some fonts explicitly designed only for use by programmers while still having character and charm. I would suggest you take a look at it if it isn't already familiar.

Hi all. I'm currently developing some homebrew for everybody's favorite handheld, the 3ds. I don't want to go too into the details of the project, as I've found when I talk about things I'm working on I'm less likely to finish them; however, I'm in need of some assistance or at the very least a friendly nod in the right direction.

I was wondering if anyone had any advice / links to learning resources on generic server implementation. I have already read through beej's guide on socket programming multiple times through. My issue is less with the minutia of how to sockets work, and more of how can I efficiently organize and abstract both the data representing the connections to each client, as well as the data each client will be sending me.

tl;dr anyone have any tips on designing a server for some homebrew I'm writing?

details you may want to know:
I'm writing it in C. Rust / C++ are not really options at this point.
The server will in effect be waiting for an approx. 2-3kb sized .png, then it will bounce that image to all connected clients.
