C++ Result

Result for C++ an implementation of Rust's Enum type Result. This C++ implementation tries to be as close to the original thing as possible. Of course, it won't be because of the language difference between the two.

Differences

and() and or() are called and_() and or_() in this implementation because and and or are keywords in C++.
To create an Err Result use the static member from_error().
A panic is a std::runtime_error.
unwrap(), unwrap_err() and expect() do not display the error value or the okay value when they panic. This is because it might not be possible to convert the type into a string.

Warning

The ability to check for equality between a Result and a value was added. However, one problem arose when this feature was added. If the template types are the same (for example Result<int, int> or Result<std::string, std::string>) then…

PixMap library in C

Libpixmap is a library to read and write pixmap image formats with a simple to use API.

Getting Started

git clone https://github.com/Noah11012/libpixmap.git

cd /path/to/libpixmap

mkdir build && cd build

cmake ..

If you want to change the install prefix, enter the following:

cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/install/prefix

make

This library contains one header and one source file. Two headers and two source files that are optional but provide filters and drawing capabilities.

Example:

clang -o program main.c another_file.c pixmap.c pixmap_filters.c pixmap_draw.c

In main.c:

#include "pixmap.h"
#include "pixmap_filters.h"
#include "pixmap_draw.h"
int main(int argc, char *argv[])
{
}

Documentation

pixmap_image_new(char const *name, int width, int height, int max_color_val, PixMapImageType type)

Creates a new PixMapImage at the path name and with the dimensions of width x height and the maximum color value of max_color_val with the PPM image type…

Looking for some contributors and help with plazar-js, a standalone JavaScript framework. I know that we have Vue, Angular and React, but I've reached the point where I started thinking that something could be done differently and maybe easier to use, if not better.

It's a young project and I'm working alone on it, as well as on documentation site therefore any help would be appreciated. Feedback is also very much welcomed in terms what should I improve, what did I do good and what did I do bad.

You can expect a new documentation site deploy every couple of days, depending on my day job responsibilities. Documentation can be found here. I still have a lot to write and update a couple of sections. Some of them are missing code snippets (parts of the core section), etc.

Best of luck to you all.

So You Just Learned has lots of issues that can be tackled with no code knowledge! It's a repo with information about current diversity and inclusion problems in the tech industry and how to help. PRs always welcome!

I would care to expand on this, but up to a certain point. At least at this moment.

My focus is on the good old trio: HTML, CSS and JS. I think that all of the popular frameworks, except maybe Vue.js, are focusing on JavaScript too much. For example, take a look at angular animations...My opinion that they should be done via CSS3, we do not need the JavaScript version.

The reason why I'm thinking like this, is, that we are pulled off off the basics of web application development when working on certain project and afterwards we are left with the knowledge of the specific framework that were used. Don't get me wrong, I'm not saying that this is bad, any knowledge is a good one, but we shouldn't be limited to only that specific one.

This way we are left without the understanding the concept behind the hood.

I guess, that the main difference would be, focus on app development with the existing technologies, speed it up with the framework, and spend as much as possible less time to learn it.

Long story short, I don't think that they meet the requirement of simplicity.

Do you like Docker?

Are you a web developer?

I'd really love if someone contributed an example Django project to github.com/nickjj/docker-web-frame....

The focus of the project is to have up to date and high quality examples on how to Dockerize a bunch of different web frameworks and technologies.

Currently, there are examples for Flask, Node, Phoenix, Rails and Webpack. If your favorite framework isn't listed, feel free to contribute it as well!

Result for C++ is an implementation of Rust's Result type in C++. If love using Result and would love to use it in C++ then this library is suppose to solve this problem.

A C++ wrapper and helper class to render images in SDL2

SDL Image Wrapper

SDLImageWrapper is a C++ wrapper around SDL_Texture for ease of rendering in SDL2.

Quick Start

Build

You will need SDL2 and SDL2_image to build and use this library. This library contains only a header and a source file. Simply include the header file and add the source file to the list of files to be built.

For example, if you have clang++ installed:

clang++ -o program main.cpp other_file.cpp `sdl2-config --cflags --libs` -lSDL2_image

In other_file.cpp:

#include "sdl-image-wrapper.hpp"
...

Of course, if you were using a build system generator like CMake you can just add the source file to the list of files for a target.

Usage

When using SDLImageWrapper you must ensure that SDL2 is initialized and that also SDL2_image is initialized. The constructor and open_image() will throw an SDLImageWrapperException if an error occurred. If a call to render_image() results in an error, an…

The Rails engine Sail has received some contribution from the members of dev.to and was featured in Ruby Weekly and also in the trending Ruby repositories! Thanks to everyone!

It is a dashboard panel for managing settings live without requiring a deploy of the application to change behavior.

We're always looking for suggestions on new setting types and how to enhance the dashboard looks.

Cheers!

Still Looking For Front End PHP Developer

For a live streaming clone

So shameless I hated my first submission being one requesting help instead of writing tutorials and giving it like I normally would.

But here we are and you asked - Looking For Front End Developer

I can script but I need a front end developer for a live streaming site that is powered using its own cryptocurrency blockchain. Some of it is already done, and for the most part seems to be mocked up too.

But I still need to find someone who can code first, ask "when moon" or "when lambo" later. Seems like everyone wants to be your manager when your at the top. So I came here to call on my kind of people!

On the flip side of things Im not the managerial type, and want to learn and am very hands on, already a daily Linux user, and very comfortable on a terminal, just lack the critical pieces needed to build a site the way I want to in the time frame I have.

Sorry hate the subject matter, and asking it here, but you did said #shameless and #promote all in the same sentence. <3

Juan F Gonzalez • Oct 31 '18

And what is the front end being developed already with? I know both PHP and Javascript so depends on the stack I can take a stab at it.

We are looking to release our open source iOS app soon, if anyone wants to jump in and iron out some usability issues:

thepracticaldev / DEV-ios

DEV Community iOS App

DEV iOS 💖

This is the repo for the dev.to iOS app. It is still a work in progress, but getting there!

Design ethos

We will grow to include more native code over time, but for now we are taking the approach of native shell/web views. This approach lost favor early in iOS days, but I believe it is a very valid approach these days. It is inspired by how Basecamp does things. Our tech stack is a bit different, but the ideas are the same.

signalvnoise.com/posts/3743-hybrid...

signalvnoise.com/posts/3766-hybrid...

youtube.com/watch?v=SWEts0rlezA

By leveraging wkwebviews as much as possible, I think we can make this all pretty awesome and sync up with our web dev work pretty smoothly. And where it makes sense, we can re-implement certain things fully native, or build entirely native features. Life's a journey, not a destination.
