Git.

The smallest utility made its way to being the largest companies must-have, the most critical part of the whole development landscape.

Using just plain C, Git can shred huge amounts of data insanely fast. It never gets old.

Git is a developer's scalpel.

Visual Studio Code! It's Microsoft showing Atom that they can copy Sublime Text better ;)

To be honest: Firefox.

I use it every day since version 3. And a piece of software which has so much competitors and can withstand my urge to change is my winner

Someone’s got to do it.
So my favourite open source project is

EmojiCode!

Another great thing is pihole.

Blocking more than 2 million domains like an afternoon breeze

Who will be the first to write "Linux Kernel"? 🤔

That'd be Linux for sure. I love how it allows its operator to do anything they please, without any lockdown or nannying. How I own the piece of software (given copyright compliance of course), rather than being just (temporarily) licensed to use it. How I can customize it into whatever shape I want. How it allows pretty much anyone to contribute. And redistribution! Yes, the hundreds if not thousands of distributions and appliances that use it! Simply amazing.

Definitely Nextcloud. Now I don't have to use proprietary software like Google drive and Dropbox anymore.

It's a shame I found out about it last week. I wish I found it sooner.

Blender.

3D modelling, UVs, texturing, animation, video editing, compositing, motion graphics, motion tracking, 2D animation, and a fucking powerful render engine? Check.
Great community? Check.
Powerful and easy scripting system? Check.
A well organized dev team? Check.
People who care about UI/UX? Check (look at Blender 2.8).
Does it compete with a major corporation that would go into sloth otherwise? Check. (If you thought M$ was shaftware wait till you see Autodesk)

There are other FOSS projects that I really like, but my vote definitely goes to Blender.

Every Open Source Project Needs a License......

Apache Software Foundation.

Because the internet would've been completely different without it.

VLC because it really is damn good. The only player which gives you a nice looking interface irrespective of the windowing system it runs upon - Gnome, KDE, XFCE, MS-Windows, Mac. And that 200% boost in audio is really helpful with files having very low audio.

Docker. I absolutely love containerising stuff, as it makes everything 200x easier to handle, and its development is also great. I'm completely in awe of it, and the only thing I'm unhappy with is how it doesn't detect the system arch and use a specific image for that (*cough* ARM64 server here *cough*)

Apache no doubt.

Reason? It is good, and it does not want to shove a commercial license into my throat like Nginx wants.

I'd say Linux but seen that around a lot so I'll go with another favourite:

OsmAnd(+)

It's basically an offline navigation app which works with downloading maps offline and then you can use navigation without Internet (gps though of course).

It's very easy to use, looks okay enough and no fucking tracking at all. I was in Switzerland recently without any service (my friends didn't have service either and their navigation relies on Internet) and this fucker saves us big time.
Not saying that there aren't any other offline navigation apps but this one is awesome imo.

Git. Not Linux, not python, not gimp, not GCC, not Emacs. Git.

Because it saves your work and you can work with other people on one project in a human way

Rust is my favourite open source project.

Because rust is fucking awesome!

Wireshark

Except I know nothing about how to use it.

Godot

It's a very lightweight game engine with a lot of features, great community and active development.

(Unity is way too bloated for me since I only make small games as a hobby)

Cpanel and plesk is just two newly invented words that means the following:
Anger
Insecurity
Hate
Stupidity
Virtual AIDS
"I am pretending to be a sysadmin"

Blender. The answer to that question is always Blender. Such amazing, huge thing.

And right after that, git, of course.

After that, probably Linux.

It's gotta be the Linux kernel.

It's so good at managing base resources on all platforms that it allows hundreds of thousands of hipsta-ass devs to write shitty code and still get decent speed.

This gem of a game. Partly cause i'm a contributor, partly cause i'm a space junkie.

Is this advertising? maybe.
Am i in love? definitely.

Linux.

Rust (: it's my favorite programming language

Definitely Godot Engine. One of the greatest and easiest Game Engines I have ever used! Lots of great features and there are getting more and more!

The inbuilt programming language GDScript is really awesome too! It's a custom language built extra for the Engine, which makes it super easy to use and integrate! The syntax is a bit like python but better.

Because it's not as old as unity or unreal engine, it's not as feature rich. But I think that's okay. It allows you to get used to the current existing features, and then heading on to the new ones.

What I really enjoy is that, just as in this community, you can just talk with the creators of the engine. Asking questions, suggesting features and discussing things! They'll answer nearly everything!

Not to mention the graphics! They are really good and are nearly able to compete against Unity!

There's also a visual language you can use. Just like Unreal Engine Blueprints! Never tried it tho...

The scenes system is very easy to understand. You basically have a lot of "components" which you can use in each of your scenes. This also allows for making simple extensions!

All in all, a great engine! If you are a game developer I can definitely recommend trying it out!

AOSP

Even though Googles decisions around it are questionable most of the time, I love that we have an (almost) completely open ecosystem for smartphones.

And the thing about it I love the most is the amazing modding community around it.

Everything KDE.

Nmap.

Anything in my Github page. Because I made them 🙃

The Linux Kernel is propably the best working example for open source.

Personally I had the most exciting experiences with open source games, like Super Tux Cart, OpenTTD, 0 A.D.
Once I watched a streamer playing OpenRCT2, but the Twitch integration server, which allows to have the names of the people in chat appear in the game, was offline. Because the game is open source, I was able to have a look at the API, write my own server in a couple of hours and share it. Was a really funny stream then!

Wine is a great project, too. I really like the idea that people cooperate with each other to bypass commercial limitations and on this way be able to play their favourite games on a free operating system.

I love materializecss.com .. I love the concept and I don't know why, but I like it ways better than bootstrap. Materialize looks kinda fresh to me - not the classic Material Design. Aaaaaand it's very easy to work with it.

PYTHON

requests lib - HTTP for humans (python)

It really is a breeze to work with! Clean and intuitive design, loving it!

Definitely Golang.
Its by far my favorite Language.
Its just so easy, yet powerful.

Citra as it let's you play 3ds games on PC and makes them look like this

PHPMailer

Because why not?

Undoubtedly it’s Node.js

elementary OS, hands down, is my favourite. They eat for breakfast the people who think Windows is easy and macOS is pretty. Fucking cannibals.

Sorry guys, I don't really care if something is open or closed source. Code just needs to work well.

Signal

for making secure communication easy to use, accessible to everyone and open-source

It's a very difficult choice for me. I use many open source things on a daily basis.
Unordered list:
-Linux
-Wireshark
-Gotop
-Ettercap
-VS Code
-PHP
-discord.js

I could mention so many libraries and frameworks but im gonna go with arduino.

For all the Java devs, Apache Commons. ☕️

I have multiple (in no particular order) :

Nextcloud : It was an idea that I had in my head as well - to take on corporations like Google in the space of personal cloud. Be free, open-source and put the users in charge.

Gitlab : The most open and transparent company that I've ever come across. And they work 99% remote. They've got features that no other players in the space have. All while putting users in control.

Fediverse social media - Mastodon, GNU Social, Diaspora (soon) : For taking a major step in the direction of putting the users in control of their data; all while enabling a decentralized social network.

Ruby : An open community and building a programming language that runs a lot of software of the world.

Python : The oldest thriving community that has a special place in the development community (and my heart)

Javascript / ECMAScript : The scripting language that grew to be a beast of it's own.

PostgreSQL by far, what an incredible and feature-packed database.

phpMyAdmin

Well, it is not my favorite open source project... I almost never have to use DBs, but when I do, it just saves my life. I can create the tables, keys without worring about any SQL command.

But day to day life is GNU/Linux, Firefox, bash/zsh, git... There are lots of opensource tools that I use, and love, everyday. :)

.NET Core
Because I use it, and it's awesome.

SignalR
Because it makes live websites easy as fuck

!rant
So for me "OH MY ZSH".. A seriously gem of a project..

Bootstrap

Thanks for allowing developers to forget about some tedious aspects of design

OpenSSL, Nginx, OpenSSH, Node.JS, V8 and Firefox

There are obviously many more :-)

AndroidOS.
Why: well it's built on Linux kernel so first good thing.
Due to open source everyone can get cheap (under $50) smartphones running on Android with millions of app to access. We can create custom ROMs.
Your one app can target billions of people around the world and so much more...

PS: half of the Play Store apps are shit.

A toss up between COSMOS or the Linux kernel, COSMOS because it's just amazing to see an open source kernel built on .NET from scratch (besides boot loader) and Linux kernel because well... Do I need to explain?

Hello, This is my first Post... Yeah!!!
Does somebody knows cool/functional plugins for Firefox?

Apart from linux, it has to be vue.js, quasar and express.js

Vue.js had made my development extremely easy, faster and managable
Quasar brought great Styling and various other powerful features to vuejs. Thus helping save even more time

And express.js don't need any explanation. Better code organization and easy to get started.

Berkeley Software Distribution

KDE. There's just so much awesome stuff under it. Plasma, Krita, Kdenlive, KDE Connect... Most of the bleeding-edge Linux desktop development is happening under KDE.

Atom. It showed me that text editors don’t have to suck. Love the One Dark theme.

Spring Frameworks and the projects surrounding it such as Spring Boot, Thymeleaf, and recently lombok. Without these API's and frameworks I wouldn't be using Java half as competently as I am.

Development is moving further and further towards containerization and it's a massive time saver.

I absolutely love the work put into Visual Studio Code.
It is a great editor, which evolves quickly and has a nice community.

Was using vim for literally everything and switched at some point to VS code and love using it since

Blender3D

Probably the most feature rich, frequently updated oss for computer graphics ever.

The project really captures the spirit of open source, most notably with it's open movie projects.

It does have a pretty steep learning curve, but taking the time to lean it is totally worth it. Not to mention comparable Autodesk software will run you thousands of $$$

Bunyan

Bunyan is a simple and fast JSON logging library for node.js services

Server logs should be structured. JSON's a good format. Let's do that. A log record is one line of JSON.stringify'd output. Let's also specify some common names for the requisite and common fields for a log record.

For me it has got to be Retroarch/Libretro (or as I've taken to call it etc.).

Retoarch is a frontend for Libretro which is an API that emulator developers can use so that I as the user don't have to worry about configuring each emulator (and some other stuff).
It's a godsend piece of software that makes it possible for someone like me to really just enjoy my (but but expanding) library of old games (that I can only dream of playing on original hardware)
Also, it's multiplatform!

I also tagged it as wk119 since this is my school setup

I think Chromium is definitely one of the best and most useful Open Source Projects, because so many modern technologies are based on it:

- Chrome + Chromium Browser
- Electron (Which is in my opinion the future of software development, as long as Web Apps don't have that many possibilities)
- Android WebViews
- Chrome OS (and Chromium OS)
- Many other Browsers like Opera, Samsung Mobile Browser, Vivaldi…

I think without Chromium the Internet wouldn't be the same today. It helped to popularize WebApps and helped to set many modern web Standards. Also, in addition with V8 it paved the way for modern JavaScript, as it provided (and still provides) developers and so also users with massive performance boosts.

R.
The statistical "scene" (if there is such thing) grew so much in recent years, because now there is a single language that everyone can use and easily share code via packages.
Before everyone used a different propietary and paid statistical software, and could not share code.

Elasticsearch.

You can't have distributed free text search and not have elasticsearch in the same sentence.

A lot of analytics companies are running because of the elasticsearch aggregation framework. And search couldn't have been faster on such mass of data.

P.S. i used to be a solr fanboy, then i met elasticsearch. Kimchy knows the best.

It's not in the top 10.
But i like Flutter

GNU/Linux

Fight me

virtual box

I can play with any os.

My top 3 open source projects are :
KDE ❤️❤️❤️❤️
Libinput gestures (allows you to do custom actions with your touchpad)
Strapi (Wich is a nodejs headless cms that gets the job done very quickly I haven't tested it in prod tho)

I like the Kubernetes open source project. Big project that has been fairly good at smoothing things out and pushing the project forward.

IntelliJ 😊

There are so many:
Arch Linux, Krita, LMMS, Open Street Map and many more.

TensorFlow, because it makes machine learning accessible to everyone.. and.. well, it gave birth to my Android counterpart <3

I wonder if Stallman is on DevRant.

My favourite opensource project is GNU

I'd say everything PS Vita related. From the emulator, Vita3K, to all the work by TheFl0w. I have followed the scene for so long now that I'm just neck deep in it.

I don't think anyone said it yet so I'll have to choose osu!. It's a rhythm game and now it is being remade as open source. It also uses a open source game engine dedicated to rythm games. The osu staff is great and the main dev (peppy) streams on twitch while making the game sometimes.

It's a great project and I hope I can contribute some day.

For me, it would be Caddy Server

Discovered it while running some researches around GoLang, where I could see that it was really useful when used with Hugo Framework.

It took me something like 10mn to configure it to run (I couldn't believe only 2 lines would make my things work), and 5 more to make it run with Docker and Traefik (another good open source project that I now use everyday).

Now all my projects where I use Docker have Caddy included o/

Flight Gear.

I had one heck of a time during my pre teen days flying airplanes and going to famous cities around the world in this cool flight simulator game. On a related memory, I think it was in 2008 or something, when Yahoo messenger was the popular thing, I sent a message to one of the main developer about how I can build planes and stuffs for the game. He responded and said something about C++ and some documentations.

This was way before I knew anything about programming. I found myself frustrated about not knowing or understanding any of the guides.

Then puberty happened.

I'll take... "osu!". I like music and rhythmic games although I know sh[BLEEP] on C#.

Software.... Firefox. Because fuck you Chrome. And git! Everybody loves git.

sl

Gotta love the silly things a community brings forth. Never fails to crank me up when I accidentally use it and kinda replenishes my energy / motivation.

Sircmpwn's sway wm, an i3 clone for Wayland, I love i3 but I'm also an advocate for the ditching of xorg. (Close to beta)

Honorable mention for anbox which tries to do a similar thing Google is doing to run Android apps natively in Linux. (Alpha)

Obviously docker, for introducing containerization concept

VIM x 2 cos 6 letters minimum. VIMVIM.

I've never been more impressed than when I discovered Linux. It's a pretty classical choice but I can't say another. It's my favorite because for every need you have, you get a solution to make it. Right now, I'm learning how xcb works to make a tool for DE like Rofi.

Most of all, Linux philosophy implies that the most popular (and almost always best) tools used on Linux are all open source. So now, I can learn xcb just by looking at the codes of other DE, I'm really in love with Linux

Anything on the Raspberry Pi.

Probably linux. It gave a lot of us job opportunities that we might of not had previously if not for linux. Android, servers...

Lately I am working using icestorm!
I know very few people know it, mainly beacuse not a lot of us works with FPGAs.
It is foundamental for the open source scene because is the only FOSS that gives you the ability to "compile" for FPGAs, otherwise you would have to use some proprietary tool.
People are building lot of things on top of that, and I hope more people start workin with FPGAs: dealing with them is still quite hard, especially if compared with MCU programming.
I am sure that in very few years we will see something very interesting in that field.

Does tv reality peoples count as open source things ?

Apache Tomcat, simply for the nostalgia.

I guess it has to be keybase. Keybase chat is now my go-to web based chat.

Using NaCl keys makes life so much easier but you have the choice of using PGP if you need to for encrypting files/text.

Since I started using Emacs two months ago I love this piece of software.

The Chrome plugin "Darkness" (I might have mentioned it before 😅)

Yes I know "Stylish" was a thing and it has been replaced, but by then I was way to invested in "Darkness" and it has some features that the others are missing; the styles are tested and maintained and it has themes to choose from.

And it has been a nice experience working with scss 😄

ElementaryOS

The distro that took away the distrohopping

I think anything from Domas (moveaxeaxeax) is beautiful, but project:rosenbridge is just a new level.

The amount of work, weeks of fuzzing and no documentation to find an entirely secret CPU that acts as a backdoor, and then watching him explain it all. It's purely amazing!

l i n u x

Org-mode as it has the potential to change your life :-)

Astonishing in how many different areas it beats the tools I used before.

From todo lists, documentation,publications or even presentations it ruled out my old workflows and the journey is not over .

- LibreNMS
- Proxmox
- Ceph

Good quality code, frequent updates and EXCELLENT documentation.
