Here's a thread on StackOverflow, how do I deter decompilation of my program?. A handful of answers recommend compiling with full optimizations. My question is... What does that mean? How does that prevent one from decompiling a program? (Of course not literally, just making it harder, right?)

I guess I'm not familiar with what side effects optimizations have to code rather than straight up compiling.

Triple Tech posted:

I don't know if this wasn't clear, that's not my post. I'm merely asking what the effects of optimization are on compiled code.

error: macro "max" requires 2 arguments, but only 1 given

Well, what line of code is giving this error?

GrumpyDoctor posted:

Is it not just that you can't share the results of anonymous functions? (How could you?) That seems too simple.

I am getting a strange error when I compile under linux (kubuntu in VM) with a project that works on Windows and Linux.

error: macro "max" requires 2 arguments, but only 1 given

The way I fixed this in the past is to go through and every time it says this for min or max I put "#undef min" or "#undef max". This makes it compile and it works, but I feel like there is something I am missing.

Here is my makefile, I'm not sure what info to add about the project to help. It uses the HL2SDK, it is a plugin for source dedicated server for the game counter strike source.

windows.h defines min and max as macros because it is retarded, maybe you are indirectly including that or something else that is as stupid.

You are apparently defining NOMINMAX to avoid that, but it loks like you are doing things in C++ and only setting that for C or something. Not sure.

Sweeper posted:

It compiles under windows without error or warning, but it fails under Linux, does Linux have a Windows.h somewhere that it includes? If so I will look to see if my project includes it and put an #ifndef or something around it.

That's pretty close. The fact that the function is anonymous doesn't really matter, just the fact that there's a parameter. Consider:

code:

one_list :: [Int]
one_list = 0 : [ x + 1 | x <- one_list ]

some_lists :: Int -> [Int]
some_lists n = n : [ x + 1 | x <- some_lists n ]

In the first case, there is obviously only one list. Once it's computed, it's done. As a result, the runtime can replace it's uncomputed definition with its computed form, saving work.

In the second case, the list depends on a parameter n. There are many lists, one for each value of that parameter. The runtime can't replace the general-case code for building a list with a computed list, because it might need the general-case code again later. So the result is not memoized automatically.

The rules are approximately as follows:

In the expression let x = foo in bar, the computation of foo will happen at most once per computation of bar.

In the expression \x -> foo the computation of foo will not be saved.

Here's a quick question: How can I run a script/whatever that will allow a text editor (eg Notepad++) to search and select all text between <div id="here"> and </div>, and delete all other text? Bonus points if it could do this with multiple sections-- keep <title>*</title> in addition to the div "here"...

Does this make sense? Thanks for any help...

Vanadium posted:

Just guessing here, maybe the SDK headers include a copy or something. Can you search them for #define max or something?

I think I found your problem!

You probably want to use x264 with mencoder as the frontend.

I looked up IDEs and found that QT was both popular and had books published on it, was available on linux, and was open source.

A few things come to mind:

- PNG decoding: maybe convert wrote palette-based files that aren't being read properly? Try playing the PNG sequence with mplayer and see if it looks right.
- Colorspace: I think mencoder converts colorspaces automatically, but you might try explicitly converting to YUV for x264.
- Muxing an H264 stream into an AVI container: Try making mencoder produce y4m (raw) output (perhaps to a special fifo file), use x264 on the raw file, then mux the resulting .x264 file with mkvmerge or mp4box.

Scaevolus posted:

As a side-note, you probably want to use x264's crf mode (-crf 18 for good quality) instead of qp & bitrate.

If you think Qt is an IDE, you have a loooong way to go. (You're probably thinking of Qt Creator, which is different from Qt.)

Also I'm really curious what constitutes "a few years" of CS education, since I think most schools stop teaching the ins and outs of programming languages around the end of the first year (sometimes moving into first semester of sophomore year).

I'm thinking about rewriting The Awful Yearbook. I've been writing a bunch of Java lately and going back to the dynamically typed PHP is a bit frightening. Am I crazy for just wanting to rewrite the whole thing? I'm also a huge fan of Eclipse now, I never was able to find a PHP IDE I really liked. Am I going to regret this?

Richard M Nixon posted:

the CS department has 3 intro CS classes that must be taken before you can move on to take whatever sort of programming you want (AI, embedded device, gui poo poo). That is 3 semesters of prereqs that are broken up as such: Class 1 is an intro to programming and goes from hello world to arrays. Class 2 goes from a review on arrays to very basic classes and functions, with pointers being the last thing covered. Class 3 is a review of memory and classes/functions, intro to modular programming, and fun things like inheritance, encapsulation, polymorphism, linked lists, trees, and the rest of the good and fun CS stuff. There is also a corequisite of discrete math I and II before any of those upper level CS classes can be taken.

Goddamn I am bored in school.

There's a programming class that doesn't even cover functions?

ErIog posted:

You see this in all manner of departments in academia. They take a real world thing like programming or foreign languages, and then they turn it into a curriculum. In turning it into a curriculum, it gets watered down over the years to prevent people from failing out of classes or dropping the major. This means that pretty much all the classes are worthless because there's never enough time to go beyond the very basics.

1 semester devoted to hello world and arrays, with functions only being introduced in a second semester. Sounds a lot like the Japanese language major I did where there were only 3 or 4 of us out of 40 Japanese majors in that graduating class that actually had working knowledge of the language enough to have conversations with native speakers and understand things like movies, television shows, and books on our own. We were only able to do this because we exercised the opportunity to study abroad. Even there, though, the classes babied everybody. The only people I knew who did really well busted their rear end studying on their own all the time outside of class.

That seems like the sort of program Nixon is in. I find it to be borderline unethical the way some schools advertise their programs in such a way that leads you to believe you will be skilled when you exit, only to railroad you into "everybody must pass" classes where nobody learns a drat thing.

The only answer for somebody like Nixon is to make sure you do all your schoolwork the best you can, and learn all the worthwhile stuff outside of classes. Make sure to create good relationships with the professors, as they can be very useful for getting jobs after you graduate. Also, network with people who are better than you in your program. You'll learn from them, and they might be able to get you hired after you graduate. You should also be networking with people in your town and community that do what you want to do. They should be able to tell you pretty easily what you need to be focusing on.

When I got out of school, I realized most of my class-mates didn't know jack poo poo. I realized the curricula I had completed were worthless, but I valued the relationships and opportunities that going to school gave me outside of my classes. I ended up getting a pretty great job right out of school due to the networking that I had done. That's how you get your money's worth in a bad academic program.

I took a semester of japanese here and failed miserably. I was expected to memorize all the katakana and hiragana characters after 4 weeks.

Dijkstracula posted:

Unrelated, but, 4 weeks?! Pansy. I tried to take Japanese in my first year, and the Monday class was devoted to the entirety of hiragana, the Wednesday class was all of katakana, and we had a quiz on both on the Friday. Now that is intense poo poo. (Suffice it to say that I got the gently caress out)

Latin was my favorite class in high school. Sadly I've forgotten 90% of it now.

Also, learning to read hiragana and katakana took me a weekend .
