Joke's on you. Saturday and Sunday aren't the weekend in every country.Sagacity posted:(btw, SVN is still worse, doing any kind of merging while trying to stay sane just sucks) We must be using different SVNs. I can barely remember last time I had a difficult merge, and the ones I have had would've been rough with any VCS, since they usually involved logical conflicts.

God, stupid people loving exhaust me. So I get in this morning I go talk to Guy and tell him "look, I think I really hosed up on Friday, this has been driving me nuts all weekend. I think you lost all your changes on Thing X that you were working on. That git command I told you to run reset your repository to the last commit, so if you had uncommitted changes, they're all gone." Guy is totally blithe and blasé about it. "No, no, I'm sure everything's fine, you've been stressing over nothing, I'm sure I didn't lose anything." I'd love for this to reassure me but he has Git Extensions open behind him and I can see he's on the same mainline that I am and there's no extra commits I don't have. Again Guy has no idea about branching or stashing so I'm 99% sure I was right, his work is gone, and he just doesn't realize it yet. But I don't argue (because there isn't any point in doing so), and hey, maybe what he means is that he has some kind of local backup and everything will be fine. I broach the subject of having an in-depth conversation about how to use git, what commits and branches are, and how we can safely collaborate and make sure nothing like this happens in the future. I get pushed off. Of course. Finally around two o'clock I hear: "Horatio...? ... I think you were right. My changes are gone." We find the WAR file from the staging server. It's on my desktop, where I copied it first thing in the morning. Guy had already overwritten the one on the staging server. We pull out the JSPs and JavaScript files. So that's something. It's the perfect time to create a branch so we can collaborate on fixing this mess. "Do you have some time right now? We can get this changes into a branch and..." "No, no, we can't put this code in a branch. It's broken right now." "...Right, yes, well, that's kind of the point of a branch, so you can work on code in a broken or incomplete state and it doesn't affect the mainline." "Oh. Well, no, let me just see what kind of progress I can make and maybe Thursday we can talk about putting it in a branch...." At this point I feel like I'm banging my head on a brick wall but I still feel responsible for loving his poo poo up so I say, "Well, I'm happy to help you try to recreate some of the Java files that were lost." "No, what I'm going to do is go online and try to find a decompiler to generate some Java from the class files in the WAR."  Well, whatever. I give the gently caress up. You wanna be a stubborn idiot, go ahead and be a stubborn idiot. I can't stop you. I owned up to it, I tried to make amends, and Lord knows I've tried like hell to implement some revision control and build management processes that aren't total trash. It's a lost loving cause.

ninjeff posted:That's what we're using now, and it doesn't scale. Your terrestrial ideas have no place in Big Space. Why doesn't it scale? You travel with your own atomic clock that stays in your reference frame. From time to time your computer checks in with the space system's central atomic clock to see how far you're off by and making an adjustment accordingly. It's not going to be exact, but time-keeping between two non-inertial frames where you don't necessarily know your velocity relative to the central clock that well is going to be impossible. The atomic clock is basically like having a clock tower; each town (space system) gets its own and from time to time some people get together to make sure that all of the clocks are running about right. I don't see us being able to do much better than that with the technology that exists today, and it's a pretty good and realistic solution And I hardly see what's terrestrial about a system of atomic clocks orbiting stars so that spaceship pilots can have some reasonably accurate way of telling time, but okay

You end up with almost exactly the original source since its bytecode and not assembly, but everything's stripped. Hope you like reading hj a = new mb().a("98403").b(Color.Red); hj b = new df(); hj c = new el().k(); and so on. You never realize how important good variable/function names are until you don't have them at all. It is theoretically possible to walk the code and reverse engineer it and rename it enough to work with, but... you don't want to have to do that. Easier to just write the code again, unless you're specifically trying to hack some 3rd party closed source software.

Is it posible to back-translate (decompile) every posible chunk of bytecode? That is for sure not the case with old-school compiled code... the optimizations usually mangle the object code in ways that just make sense in assembly, but not in a high level language. (I had once to look at a dissassembled fragment of compiled PL/I code and it was an absolute mess...).

I don't know about Java but it's not possible with .NET. The runtime has more features that for example C# doesn't support (like global variables).

I've dug around in .net bytecode a bit and it is more or less a direct transcription of the source; often even trivial constant-foldings didn't seem to be performed, presumably because the loader/JIT would take care of that. I would assume that JVM bytecode is similarly straightforward.

Java decompilers like Jad and JD actually work surprisingly well, and produce fairly readable code (big caveat: if it hasn't been run through an obfuscator). The biggest problem they usually have is with exception handler blocks -- those are tough to reverse engineer correctly a lot of times. I've used them on numerous occasions to figure out what a library was doing when the source wasn't available. Keep in mind that even private method names and fields are preserved by the compiler for reflection purposes, so the biggest place where you lose names is with local variables and parameters.

Java/C++ (probably others) make higher-level structure easier to decompile due to various language features such as overloading - that information has to make it into the binary, and now you have type-information of call arguments. Decompiling C code? Good luck with that, you can see it accessing a 32-bit register and try to guess what type it is based on what it does next. Java decompilation is how all minecraft mods are made. You run the .jar through an obfuscator with the purpose of renaming A, B into usable class names (Block, Player, etc) via a community-updated database. Then you decompile it, make your modifications/addon, recompile and re-obfuscate back to the original class names - which now mangles your references as well. Compare the stock .jar to the produced .jar, extract the files that changed and presto, a mod that you can distribute. There's a set of patches you can add that do some code cleanup for readability (where the decompiler went off the rails) but it's usable. It's amazing that it works at all, honestly. The nightmare mish-mash of competing and conflicting infrastructure in the modding community is a horror all on it's own though.

Yeah, I spent a good bit of a year working on a fairly ambitious minecraft mod, and slowly lost my mind due to complete rewrites of what little and lovely common APIs existed (which were SUPPOSED to provide a static link target so you wouldn't have to break your mod and rewrite the drat thing every loving minecraft patch, except the stupid APIs changed as much as minecraft did!) I'm honestly pretty loving pissed at Notch for making a big deal out of an official API, talking about going so far as to charge money for API support, and then just dropping the whole thing on the community and walking away. That game could be SO much more, but gently caress, I can't be bothered to keep up with it. Its a real coding horror. They refactor EVERYTHING every loving week! And Documentation? What's that? Nope I've decided to just work on my own game from scratch in my free time, and I'm all the happier for it.
