Open source ≠ Source availiable
Example of non open source programs with source code https://en.m.wikipedia.org/wiki/List_of_proprietary_source-available_software
Open source ≠ free software
Open source inherently means you can compile the code locally, for free. You can’t necessarily redistribute it, depending on the license, but I’m not aware of a “you can compile this source for testing and code changes only but if you use it as your actual copy you are infringing” license.
I am very much open to correction here.

Open Source means more than that. It is defined here:
If you use the phrase “open source” for things that don’t meet those criteria, then without some clarifying context, you are misleading people.
for free.
Free Software is not the same as “software for free”. It, too, has a specific meaning, defined here:
https://www.gnu.org/philosophy/free-sw.html
When the person to whom you replied wrote “free software”, they were not using it in some casual sense to mean free-of-charge.

Where are all those free beer I always hear about?!
Have you tried installing homebrew?
I know where the hops go, but where am I supposed to put the cereal ? I think I ruined my disc drive
Floppy drive. That’s why you malt it first.
Most free software is also open source and vice versa, but not all, the difference usually lies in the licence, this stackexchange answer gets it pretty well
According to the Open Source Initiative (the folks who control whether things can be officially certified as “open source”), it basically is the same thing as Free Software. In fact, their definition was copied and pasted from the Debian Free Software guidelines.
I think InnoSetup belongs on that list as wel.
You are talking about free softwares there are nonfree licenses which provide source code
There are apps having source public but does not have any developement practice like of open sauce

In this thread: Programmers disassembling the joke to try and figure out why it’s funny.
Cute. It would be funnier if it was correct.
For people interested in the difference between decompiled machine code and source code I would recommend looking at the Mario 64 Decomp project. They are attempting to turn a Mario 64 rom into source code and then back into that same rom. It’s really hard and they’ve been working on it for a long time. It’s come a long way but still isn’t done.
I thought they were done already?
There is still some stuff that needs documenting, but the original goal of recompiling the created source code into the ROMs has been achieved. People are still actively working on it, so in that sense it’s maybe never done.
No, it is wrong. Machine code is not source code.
And even if you had the source code it may not necessarily qualify as open source.

A decompiler doesnt give you access to the comments, variable names, which is an important part of every source code

But it is extremely time-consuming. Open source code makes it transparent and easy to read, that’s what it is about: transparency
A decompiler won’t give you the source code. Just some code that might not even necessarily work when compiled back.

From the point of view of the decompiler machine code is indeed the source code though

A fancy way to say do nothing is not the same as translating back and forth. Example: Show me the intermediate translation.

Having access to the source code actually makes reading machine code easier, so you’re also wrong on this entirely different thing you’re going on about.
well assembly is technically “source code” and can be 1:1 translated to and from binary, excluding “syntactic sugar” stuff like macros and labels added on top.
The code is produced by the compiler but they are not the original source. To qualify as source code it needs to be in the original language it was written in and a one for one copy. Calling compiler produced assembly source code is wrong as it isn’t what the author wrote and their could be many versions of it depending on architecture.
But those things you’re excluding are the most important parts of the source code…
By excluded he means macro assemblers which in my mind do qualify as an actual langauge as they have more complicated syntax than instruction arg1, arg2 …
Okay, boomer here, be gentle.
So back in the ‘70s I dabbled in programming (now called “coding”, I hear). I only did higher-level languages like Fortran, Cobol, IBM Basic, but a friend had a job (at age 13!) programming in assembler. Is assembler now called assembly, or are they different?
It’s still called programming, coding is the same thing. Assembler more commonly refers to the utility program that converts the assembly code to machine code while assembly refers to the code itself, but the term assembler code is also valid. It’s uncommon to simply call the code assembler because it would be easily confused with the utility program.
Yep, some call it assembly, others call it assembler
(at age 13!)
c/suddenlyfactorial
Easier to say than “at age 6227020800”
I thought that the assembler is a specific program that translates mnemonics into the corresponding machine code. Perhaps in early computing this was done by hand so a person was the assembler (and worked in assembler), but now that is handled by software (and supports various macros). So programming in assembly would generate a stream of text that must be assembled by an assembler. (Although I have heard people refer to programming in assembler as well, just not often.)
I hear people say “program in assembler” but IMO that’s wrong. I’d say you write the code in “assembly language” (or better yet, the actual architecture you’re using like “x86 assembly”) but you “assemble” it with an “assembler”. Kind of like how you could write a program in the “C language” and “compile” it with a “compiler”
A compiler and an assembler do wildly different things though. An assembler simply replaces mnemonics while a compiler transfers instructions to a whole other language.
Depends on the language, really… C maps pretty closely to assembly language, it’s not as simple as one mnemonic to one machine code byte, more like tokens get mapped to sequences of machine code, a function call translates to some code that sets up a stack frame, a return tears it down…
I was too young/poor to afford an assembler for my 6502 so I wore out the assembly long hand on a legal pad and then manually converted each operation to machine code.
Needless to say my programs done this way were exceptionally simple, but it’s interesting to understand the underlying code.
It just occurred to me that AI in the nearish future will probably/almost certainly be able to do this.
It was a staple of Asimov’s books that while trying to predict decisions of the robot brain, nobody in that world ever understood how they fundamentally worked.
He said that while the first few generations were programmed by humans, everything since that was programmed by the previous generation of programs.
This leads us to Asimov’s world in which nobody is even remotely capable of creating programs that violate the assumptions built into the first iteration of these systems - are we at that point now?
No. Programs cannot reprogram themselves in a useful way and are very very far from it.
Eh, I’d say continuous training models are pretty close to this. Adapting to changing conditions and new input is kinda what they’re for.
Very far from reprogramming though. The general shape of the NN doesn’t change, you won’t get a NN made to process images to suddenly process code just by training it.
Then how does polymorphic/self-modifying code work?
It doesn’t or do you have serious applications for self-modifying code?
Some use it for causing millions of dollars in damage.
are we at that point now?
Nope, but we’re getting there.
Do what?
It’s honestly remarkable how few people in the comments here seem to get the joke.
Never stop dissecting things, y’all.
As above so below, the microscopic and the macroscopic
IDA Pro (a disassembler) is closed source but came with a license that allowed disassembly and binary modification. Unfortunately, that’s no longer the case.
Why not use that NSA tool they released
Ghidra is open source even before you run the disassembler 🤯 great anecdote
Joke aside, that’s kind of like claiming that any web frontend is open source because you can access the built, minified and often obfuscated source of it.
So true! I have been “hacking” some chrome extensions recently, do you know of a tool for reverse engineering JS?

And so you add a hashing check. But then that can be removed.
So you need one in the OS but that can be removed.
So you need one in hardware.
In other words no matter how clever you are there’s always a way to monkey with something unless you have absolute control from silicon on up.

While DRM is the bane of everybody there are cases where trust and integrity is important and it’s an intriguing look into how hard it is to manage.

Nah, when the user wants to ensure trust and integrity in his own system, it works just fine. The problem comes when the user who needs to be able to access the data is simultaneously the adversary who needs to be stopped from accessing the data.
In other words, it’s one of those situations where the fact that it’s hard to manage is a gigantic clue that it’s wrongheaded to try to do so in the first place.
I agree. I mean when doing secure channel communications or weapons systems or health biometrics.
There are cases where you need to be sure of the integrity of the data and environment
