What's open source?

Meme_master235

So I just saw open source and I'm like “what does that mean?” can anyone tell me?

You can know for sure what the program does
Other people are able to review your code for bugs and report them to you
People can learn from it
Disadvantages include:
Make piracy easier
Eliminate the ability to place ads on your software
Make it easier for others to hack your software

mostly correct but you can see .exe files they are just encrypted.

Another example is Apple (you can't even get MacOS on anything other than a Mac)

Mr_rudy

there is also many different licenses for open source software which says what you can or cannot do

for example:

SORRY NECROPOST IGNORE THIS PLEASE

Many people here are posting incorrect answers - they are referring to what's called “source available.”

Source available means “wow! I can see the code!”
For example, Unreal Engine is source available.

Open source, however, is much more than just “wow! I can see the code!”
Open source means you can see the code, AND you additionally have the ability to:
- Contribute back to the code
- Fork off the code (somewhat similar to a Scratch remix)
- Distribute a copy to your friend
- etc.

Open source projects are open source if they have an “open source license”, for example the MIT license.

Open source is also heavily related to a concept known as “free (as in freedom)”, pertaining to liberty, not price.
Free software and open source share many similarities, and open source started off as an alternative term to “free software”. However, they have both developed and are not exactly the same nowadays. If you want to learn about free software head to www.gnu.org.

the when f5 is clicked part is just so relatable (what does f5 even do anyway)

Since the last post was 2 days ago, I'll also comment on this

Open source is where you can not only see the code, but also modify and/or contribute to the software freely without restriction (of course one of the devs will have to approve your change when you're contributing). Additionally, you can “fork” the project, where you can change it on your own terms from there (Kind of like remixing, but some open source licenses don't require you to give credit)

Proprietary programs, in stark contrast to open source, usually don't allow you to distribute copies of it without authorization. Also, they're only available in their already-compiled state (compilation is where code is converted into actually executable machine code FYI), so they would have to be reverse-engineered, which in some cases isn't even allowed.

Source available is just proprietary but you can look at the source code (but doing anything with the code other than looking at it is typically not allowed)

A very common misconception is that open source simply means that the programs source code is able to be viewed, but this could not be further from the truth. To put it very simply: open source software is software that does not limit what you can do with it and does not limit your ability to distribute or modify it. In short: open source software not only lets you see the source code, but also do nearly anything with it.

Well put. For example, to bring it back to Scratch, @yippymishy, the creator of Blockbit, put the server source code on GitHub. That's open source, and I'm allowed to (and I did) download it and modify it a bit to see what it does.

500th post!

an .exe file (and just executeables in general) is simply the source code compiled into a binary, there are ways to decompile it (using tools like Ghidra), but its' output will be a very messy script. So it's not like they're “just encrypted”, because they can't get “de-encrypted” to the original source code.
