Do we know what the format on stdin is?

an skeleton posted:No? Then I'm not sure how you're supposed to write a method that takes a point on stdin. There's no established format. an skeleton posted:also, is anyone out there is listening, how do I add an integer to a class, such as "class = class + 4"? Well, let's get this straight. You're adding an integer not to a class, but to an instance or object. You need to define an operator+(int offset);. I don't know what adding a number to a point or to a line may do.

"Make this code work." It would be nice having an actual specification on what it's supposed to do, but well, it's up to an skeleton to write a solution. an skeleton: You should probably go read up on operator overloading, how to declare them, conventions for implementing them and what the various ones do. Here's a link, C++ FAQ Lite on operator overloading.

How do you guys generally write regex? For one-time use, I just do whatever. I'll write a 50 character regex where I don't remember what the 1st 10 characters do after finishing the last 15 For longer use / group use, I split them with comments. //Cut off Leading and Trailing func("/^ +(.*) +$", "$1") //Check for and remove companyName func("(.*)" + myCompany + "(.*)", "$1$2") My coworker says that's sacrificing too much speed for the sake of readability. Is there really a large performance downgrade from using multiple smaller regex? edit: language agnostic here, I'm just talking about in general MeruFM fucked around with this message at 19:27 on May 9, 2012 |

My company is trying to set up an OCR system that converts scanned documents into Excel spreadsheets. Often, data points will get lumped into the same cell when they should be in separate columns. For instance, in the documents I convert in one cell I get: 1,205 Units 02.02.2012 (this means 1,205 units delivered on the 2nd of February) I need to delete "Units" and shift the date to the column on the write. How would I write a macro to automatically do this?

This is a fun one. I'm making a call to a (supposed) 1.2 SOAP webservice in java. The call is in a lifecycle module in a glassfish 2 domain. I have no control over the service, as it's made by a contracter. Everything works great in the normal flow, but if the service returns a fault (for whatever reason) the service is handling the fault reporting in the 1.1 SOAP style, causing our calling code to throw an exception when it tries to parse out the improperly formatted message. The real fix is for the contractor to fix his poo poo, but in the meantime, I'm tasked at doing a quick fix. Is it possible to process the response (I've got a xsl transform that will put it in the proper format) before the java throws the exception? Maybe with a client side message handler?

I apologize if this question has already been asked in this thread a lot but almost 200 pages is a lot to go through! I code C++ at work from time to time and it's the language I'm most familiar with. However most of this coding goes through a front end program so I never have to do any GUI's or windows coding. I really want to branch out into writing a some standalone custom apps for personal use (and maybe game programming if I find some more free time) so I would really like to go about out creating my own custom GUIs and learn the basics of programming in Windows. Where is the best place to start? The only book I can find that is highly recommended is Charles Petzolds Programming Windows but that is over 10 years old and I'm sure somewhat dated. Is it still the defacto place to start? Should I skip the windows API and learn something like MFC instead? Is Visual Studio required (I'm on a small budget) or can I make do with a free IDE like code blocks. Keep in mind I'm not trying to do anything too complicated and I'm willing to put in some effort. If I could just get some guidance on where I should start or what different paths are out there I would greatly appreciated it!

Saying no to MFC seems to be the wisdom. Petzold's book is a good place to start, if you want to write Win32 apps, and understand the Windows message loop and general fugly Win32 ways of doing things. It's easy to follow. Petzold isn't exactly a good programmer, or at least the part of him that wrote the book isn't, so I wouldn't take some things as a great example for best practices. His book will, however, tell you what's there, how to do it, and what Windows things are made out of, when it comes to GUI programming. I've found it a decent base (being already a C++ programmer) to build other knowledge on top of. You don't need Visual Studio, but hey, Visual C++ Express is free and useful. (Otherwise you'd use MingW and Code::Blocks? But Visual C++ Express is a good IDE.)

And if you want to try some game programming later you can look into XNA (also free).

In my experience WPF really shines when you're doing some sort of CRUD application- databinding makes wiring up data structures to datagrids and forms braindead easy. The nested layout components WPF provides seem much more straightforward and inuitive to use than HTML divs/spans or Swing layout managers. Creating animations can get ridiculously complicated, though.

It's free under LGPL, pay for even less restrictive commercial licensing. It's a C++ based UI framework, so yes, you can definitely use C++ for the back end logic (although note that the framework uses QString and the Qt Template Library rather than std::string and STL). They've also got good Visual Studio Express integration, in addition to their own IDE. I can't recommend any books, but they've got pretty good documentation, and I didn't find it particularly hard to just dive into. As far as ancient Windows version support, some quick googling says that Qt 4.4.3 is compatible with Windows 98, and some later versions may be possible to run with some more effort, if you don't do certain things.

Until you get templates it will probably feel like a struggle. It's the most beautiful thing to whip up a data template, throw a collection of business objects (or view models) at it, and end up with a nice visual representation.

I'm applying to a Gamedev college (and the application is entirely portfolio based) in Australia soon, purely because it'll be a fun 2 years, even if it's a fairly corny college (because the best way is usually to do a compsci degree and then just dev games on the side anywho, but I don't have access to a good compsci degree for now, so I'm going here instead, plus it'll be a bit more relaxed). I need to demonstrate to them that I can program for me to get in. It's supposedly fairly easy to get in but I want to give it my all, so I've been thinking of the best thing to demonstrate my ability. At first I was thinking I'd make a small game, seeing as I've never really finished a game before, I tend to make tons of little engines and prototypes, but no polished products, but that would entail graphics and music more than anything, as games themselves are pretty easily programmed, and I don't have access to graphics or music, plus the fact that they're teaching you how to make games, so I doubt they'd expect you to know how to make them already. So I've decided to go with a fun Demoscene program, such as this: https://www.youtube.com/watch?v=sFCxV5PsusQ I'm going to make it a little higher quality, and it probably doesn't need to be made with large pixels such as that video (because it's running on modern hardware), but I'm wondering if: A. Is this the best way to do it? It's certainly the most fun way to do it, and is basically like a portfolio when submitting 3D work or whatnot, but for showing off programming skills. If you think it's not, what better ways are there? B. If you like this idea, is there any things in specific you would recommend that could be cool to add? So far I've got in mind is a liquid/smoke sim, shadowcasting, lightning, some form of perlin noise based clouds or somesuch, and a rotating ascii cube or somesuch. There's a ton of opportunity here and I'm curious if anyone has any cool ideas. Edit: Forgot to mention, I know Python, Java, C++, C#, and Lua (Plus some web coding languages, but they're not for games). I'm probably going to be using C++ or Python for this.

There's a ton of opportunity here and I'm curious if anyone has any cool ideas. I don't know if it's feasible for you, but one thing I would love to see in games in the future would be true procedural sound generation, i.e. sound from objects not based off sampled sound, or only loosely based on samples. One thing in particular I have in mind for this, I sometimes play Railworks (train simulator), and it severely annoys me how it can be very obvious when it cuts between different samples for different engine speeds. If the sound was instead generated based on what the engine was doing (e.g. some basic modelling of pistons, generators, their movement, used to produce the sound), that could give a more realistic experience. Something that might be interesting to try for that could be an interactive demo where the user could wave around a tree branch with leaves, and it produces some sound based on the movement and number of leaves on it, moving it faster would produce more swooshing sounds, but would also shake off leaves which would change the sound in later movement.

Jewel posted:but I don't have access to a good compsci degree for now, so I'm going here instead, plus it'll be a bit more relaxed  The answer is to get access to a good comp sci degree instead of wasting your life for two years in some lovely gamedev scam. There are two benefits to a CompSci degree: - it teaches you comp sci, puts you together with likeminded students, is challenging - as a signaling mechanism that you're not some lazy redneck lovely gamedev programs in the middle of Australia lack both of these. "Good" gamedev programs lack both of these. I know people. One went to a game dev program in Redmond, WA. He left because most of the other students there were retarded, the CS material was easy, the whole thing was uninteresting and not an education. And that was a game dev program people can recognize by location. I met him in college because living in Troy for four years was a better idea than finishing the gamedev program. The other has interviewed job applicants a lot. Everybody he saw from a gamedev program was an absolutely lovely candidate definitely not worth hiring, except for one guy who was okay. Don't go to "gamedev college". It would be better to go to clown college. code:code:

Jewel posted:any job is better than none. Oh man... Prepare to be disillusioned soon, then. There are legitimate gamedev colleges out there, but if you want a CS education, go to a CS school. If you don't want a CS education, to be absolutely honest you're better off either getting a major in something else if you want the college experience, or just starting to apply to regular development jobs. If you have a decent portfolio, can adequately communicate ideas, and seem competent all around, a degree is rarely a showstopper. Maybe press your luck and get an internship with a major or local software development company or maybe even a game studio. Sometimes getting your foot in the industry is all you need. Oh, and also, "I don't have money to go to a big school" isn't really a good reason for anything. Scholarships don't require a lot of effort to get, and sometimes just making an appointment with the school's finance department to talk with them about what you can afford is enough effort to them to get you on a special budget. They want to enroll you into their school over others, and finance is usually the first barrier they remove.

speaking of degrees, I just graduated with a BS in comp sci and am working fulltime as a dev for the Financial dept of my University. Im planning to be here through the end of the year, but after that it's either go for a masters or just try to get a job somewhere in the Bay. Anyone know if getting a masters would be useful at all? I'm guessing "not really", but what about if I wanted to end up doing research (for a private company, not in academia).
