• What kind of math should I be expecting in advanced programming?

  - by I_Question_Things_Deeply

  And I don't mean just space shooters and such, because in non-3D environments it's obvious that not much beyond elementary math is needed to implement. Most of the programming in 2D games is mostly going to involve basic arithmetic, algorithms for enemy AI and dimensional worlds, rotation, and maybe some Algebra as well depending on how you want to design. But I ask because I'm not really gifted with math at all. I get frustrated and worn out just by doing Pre-Algebra, so Algebra 2 and Calculus would likely be futile for me. I guess I'm not so "right-brained" when it comes down to pure numbers and math formulas, but the bad part is that I'm no art-expert either. What do you people here suppose I should do? Go along avoiding as much of the extremely difficult maths I can't fathom, or try to ease into more complex math as I excel at programming?

• What does composability mean in context of functional programming?

  - by Surya

  What do functional programmers mean when they say a certain thing is composable or not composable? Some of the statements of this sort that I've read are: Control structures are not composable. Threads do not compose. Monadic operations are composable.

• Introducing Programming To a Mathematician

  - by ell

  I currently am a programmer, I'm almost 16 years of age and have pretty much narrowed my careers down to something involving a Computer Science degree or Electrical Engineering degree (I know they are quite different but this question is about my friend) but my friend isn't so sure. He is very interested in maths and is very good at it and I think he would enjoy programming but he isn't willing to try it (edit he is willing to try but has never done before). Can anyone give me an suggestions for a language or tool that he could dabble in programming (at a reasonably basic level I assume) to solve maths problems or involve some kind of maths. As I say he enjoys maths a lot but I think he would enjoy programming, the problem is I don't want him to be put off by the stuff that isn't relevant at introductory levels such as memory allocation et al. I know that is very important but the point is that I want him to learn a bit of programming with maths then hopefully if he is interested enough he can start learning programming as programming. Thanks in advance, ell. Edit: Its not that he's completely uninterested - more that he hasn't actively explored the area before, maybe because he isn't informed about it. I wouldn't want to force him to do something he doesn't want to, I see this as more of a little push so that he can learn about programming. If he doesn't like it - fair enough, I can't control that and don't want to but if he turns out to enjoy it - this push will have been the right thing.

• Programming in academic environment vs industry environment [closed]

  - by user200340

  Possible Duplicate: Differences between programming in school vs programming in industry? This is a general discussion about programming in the industry environment. The background story is that my colleague sent me a very interesting article called "10 Things Entrepreneurs Don’t Learn in College." The first point in that post is about the author's experience of programming in the academic environment vs industry environment. After finishing a 4 year Computer Science degree course, I am currently working in the academic environment as a developer, mainly writing Java, J2EE, Javascript code. I know there are differences between academic programming and industry programming, but I was shocked after reading that post. Trying to avoid this happening on me in the future, or the others. Can anyone from industry give some general advice about how to program in industry. For example, What exactly happens when a task is received? What is the flow from the beginning to the end? What are the main differences between the programming in industry and academia? Is it more structured? Are more frameworks used? It would be great if some code examples could be given. Thanks.

• Inspiring the method of teaching. Example- C++ :)

  - by Ashwin

  A year ago I graduated with a degree in Computer Science and Engineering. Considering C++ as the first choice of programming language I have been in the process of learning C++ in many ways. At first - five years back - I had many conceptions, most of which were so abstract to me. It started when I knew almost everything about Structs in C and nothing about Classes in C++. I went through a great time experimenting them all and learning a lot. I had a hard time evaluating Procedural programming vs Object-Oriented Programming. Deciding when to choose Procedural or Object-Oriented Programming took a great deal of patience for me. I knew that I cannot underestimate any of these Programming styles... Though Procedural programming is often a better choice than simple sequential unstructured programming, when solving problems with procedural programming, we usually divide one problem into several steps in order regarded as functions. Then we call these functions one by one to get the result of the problem. When solving problems with Object Oriented Priciples we divide one problem into several classes and form the interaction between them. Evaluating these two at the beginning (as a learner) required a lot of inspiration and thoughts. Instructing to think step by step. Relative concepts to understand deeply. Intensive interests to contrast both solving in both POP and OOP. If you were ever a mentor: What ideas/methods would you teach to students in which it will Inspire them to learn a programming language (in general, computer sciences)?

• WPF Global Resources in App.xaml

  - by Ryan

  I have created a custom Treeview control and am trying to access the HierarchicalDataTemplate resource of this control from another window in the same project. I have placed <ResourceDictionary Source="/Controls/TreeView/Themes/Generic.xaml"/> into my App.xaml file. Everytime I run, I get an error saying that it can not find the resource key "scene" - the name of the HierarchicalDataTemplate from my custom control. How can I access this template? Thanks

• Join ACM, join IEEE, or read programming books?

  - by Laura

  I read blogs and listen to podcasts, and I own many of the "classic" programming books. For the money, what kind of printed material would you say is the most valuable to keep current in software engineering -- books, or magazines from professional organizations such as ACM and IEEE? Which organization has the best periodicals?

• Managing of shared resources between classes?

  - by Axarydax

  Imagine that I have a several Viewer component that are used for displaying text and they have few modes that user can switch (different font presets for viewing text/binary/hex). What would be the best approach for managing shared objects - for example fonts, find dialog, etc? I figured that static class with lazily initialized objects would be OK, but this might be the wrong idea. static class ViewerStatic { private static Font monospaceFont; public static Font MonospaceFont { get { if (monospaceFont == null) //TODO read font settings from configuration monospaceFont = new Font(FontFamily.GenericMonospace, 9, FontStyle.Bold); return monospaceFont; } } private static Font sansFont; public static Font SansFont { get { if (sansFont == null) //TODO read font settings from configuration sansFont = new Font(FontFamily.GenericSansSerif, 9, FontStyle.Bold); return sansFont; } } }

• Searching Techniques/Algorithms for Resources over a given area

  - by Raydon

  I have a flat area with nodes randomly placed on this flat surface. I need techniques which are able to take a starting point, move in a certain way (the algorithm), find nodes and continue searching. I do not have an overall view of the surface (i.e. I cannot see everything), only a limited view (i.e. 4 cells in any direction). Ideally, these methods would be efficient in the way that they work. Any points in the right direction would be greatly appreciated.

• Best resources for starting Jython

  - by Eric Wendelin

  I just got my first Jython (and Python) project, and I was wondering what documentation, IDEs, etc. are best suited to a Java buff like me. I know there are a lot of questions about starting out with Python, so I'm asking for things that might be specific to Jython. Where should I start? If it helps, I'm running Linux and Solaris only.

• Create a CBitmap from Resources ID

  - by Smashery

  I need to fill a CImageList with a number of bitmaps which are stored in separate bmp files (rather than as a single bmp with numerous parts). I assume I need to create a CBitmap so I can call the Add method of CImageList. So how might one create a CBitmap object using only MFC Resource IDs?

• Managing StringBuilder Resources in C#

  - by Jim Fell

  Hello. My C# (.NET 2.0) application has a StringBuilder variable with a capacity of 2.5MB. Obviously, I do not want to copy such a large buffer to a larger buffer space every time it fills. By that point, there is so much data in the buffer anyways, removing the older data is a viable option. Can anyone see any obvious problems with how I'm doing this (i.e. am I introducing more performance problems than I'm solving), or does it look okay? tText_c = new StringBuilder(2500000, 2500000); private void AppendToText(string text) { if (tText_c.Length * 100 / tText_c.Capacity > 95) { tText_c.Remove(0, tText_c.Length / 2); } tText_c.Append(text); } Thanks.

I don't want to populate the multiline textbox with this new information so frequently because that kills the performance of the application, so I'm saving it to a StringBuilder. Every so often, the application copies the contents of the StringBuilder to the textbox and wipes out the StringBuilder contents.

• Replacing/Adding resources (icon) programmatically in c#?

  - by reverendo

  I am trying to replace (or add in the case it doesn't exists) icons from .exe files using c#. So far I got this: string filename = "c:\\test.exe"; IntPtr hResource = BeginUpdateResource(filename, true); if (hResource.ToInt32() == 0) throw new Exception("File Not Found"); byte[] ico = System.IO.File.ReadAllBytes("C:\\icon.ico"); IntPtr unmanagedPointer = Marshal.AllocHGlobal(ico.Length); Marshal.Copy(ico, 0, unmanagedPointer, ico.Length); if (UpdateResource(hResource, "Icon", "1", 1033, unmanagedPointer, Convert.ToUInt32(ico.Length)) != false) { MessageBox.Show("Updated"); EndUpdateResource(hResource, false); } Marshal.FreeHGlobal(unmanagedPointer); "Icon", "1", 1033 <- I got this data by opening test.exe with Resource Hacker. I do get the messagebox "Updated", and if I open the resulting exe in Resource Hacker the resource gets replaced but the icon doesn't appear, its just empty. Also that code wont replace, the type "Icon" in the resource, it will delete everything and add that "Icon" and if I use BeginUpdateResource(path, false); it will not replace it neither but it will add ANOTHER "Icon". Where can I find an example to replace/add the icon using c# disregarding the name the resource use for the icon or if the resource doesn't exist?

• Assembly Resources Expression Builder

  - by João Angelo

  In ASP.NET you can tackle the internationalization requirement by taking advantage of native support to local and global resources used with the ResourceExpressionBuilder. But with this approach you cannot access public resources defined in external assemblies referenced by your Web application. However, since you can extend the .NET resource provider mechanism and create new expression builders you can workaround this limitation and use external resources in your ASPX pages much like you use local or global resources. Finally, if you are thinking, okay this is all very nice but where’s the code I can use? Well, it was too much to publish directly here so download it from Helpers.Web@Codeplex, where you also find a sample on how to configure and use it.

• Undocumented Secrets of MATLAB-Java Programming, un livre de Yair Altman, critique par Jérôme Briot

  Undocumented Secrets of MATLAB-Java Programming de Yair Altman D'après l'éditeur : Citation: For a variety of reasons, the MATLAB®-Java interface was never fully documented. This is really quite unfortunate: Java is one of the most widely used programming languages, having many times the number of programmers and programming resources as MATLAB. Also unfortunate is the popular claim that while MATLAB is a fine programming platform for prototyping...

• Design Pattern Books, Papers or Resources for Non-Object Orientated Paradigms?

  - by FinnNk

  After viewing this video on InfoQ about functional design patterns I was wondering what resources are out there on design patterns for non-object orientated paradigms. There are plenty out there for the OO world (GOF, etc, etc) and for architecture (EoEAA, etc, etc) but I'm not aware of what's out there for functional, logic, or other programming paradigms. Is there anything? A comment during the video suggests possibly not - does anyone know better? (By the way, by design patterns I don't mean language features or data structures but higher level approaches to designing an application - as discussed in the linked video)

• People != Resources

  - by eddraper

  Ken Tabor’s blog post “They Are not Resources – We Are People” struck a chord with me.  I distinctly remember hearing the term “resources” within the context of “people” for the first time back in the late 90’s.  I was in a meeting at Compaq and a manager had been faced with some new scope for an IT project he was managing.  His response was that he needed more “resources” in order to get the job done.  As I knew the timeline for the project was fixed and the process for acquiring additional funding would almost certainly extend beyond his expected delivery date, I wondered what he meant.  After the meeting, I asked him what he meant… his response was that he needed some more “bodies” to get the job done.  For a minute, my mind whirred… why is it so difficult to simply say “people?”  This particular manager was neither a bad person nor a bad manager… quite the contrary.  I respected him quite a bit and still do.  Over time, I began to notice that he was what could be termed an “early adopter” of many “Business speak” terms – such as “sooner rather than later,” “thrown a curve,” “boil the ocean” etcetera.  Over time, I’ve discovered that much of this lexicon can actually be useful, though cliché and overused.  For example, “Boil the ocean” does serve a useful purpose in distilling a lot of verbiage and meaning into three simple words that paint a clear mental picture.  The term “resources” would serve a similar purpose if it were applied to the concept of time, funding, or people.  The problem is that this never happened.  “Resources”, “bodies”, “ICs” (individual contributors)… this is what “people” have become in the IT business world.  Why?  We’re talking about simple word choices here.  Why have human beings been deliberately dehumanized and abstracted in this manner? What useful purpose does it serve other than to demean and denigrate?

• Scaling Literate Programming?

  - by Tetha

  Greetings. I have been looking at Literate Programming a bit now, and I do like the idea behind it: you basically write a little paper about your code and write down as much of the design decisions, the code probably surrounding the module, the inner workins of the module, assumptions and conclusions resulting from the design decisions, potential extension, all this can be written down in a nice way using tex. Granted, the first point: it is documentation. It must be kept up-to-date, but that should not be that bad, because your change should have a justification and you can write that down. However, how does Literate Programming Scale to a larger degree? Overall, Literate Programming is still just text. Very human readable text, of course, but still text, and thus, it is hard to follow large systems. For example, I reworked large parts of my compiler to use and some magic to chain compile steps together, because some "x.register_follower(y); y.register_follower(z); y.register_follower(a);..." got really unwieldy, and changing that to x y z a made it a bit better, even though this is at its breaking point, too. So, how does Literate Programming scale to larger systems? Does anyone try to do that? My thought would be to use LP to specify components that communicate with each other using event streams and chain all of these together using a subset of graphviz. This would be a fairly natural extension to LP, as you can extract a documentation -- a dataflow diagram -- from the net and also generate code from it really well. What do you think of it? -- Tetha.

• Different programming languages possibilities

  - by b-gen-jack-o-neill

  Hello. This should be very simple question. There are many programming languages out there, compiled into machine code or managed code. I first started with ASM back in high school. Assembler is very nice, since you know what exactly CPU does. Next, (as you can see from my other questions here) I decided to learn C and C++. I choosed C becouse from what I read it is the language with output most close to assembler-written programs. But, what I want to know is, can any other Windows programming language out there call win32 API? To be exact, like C has its special header and functions for win32 api interactions, is this assumed to be some important part of programming language? Or are there any languages that have no support for calling win32 API, or just use console to IO and some functions for basic file IO? Becouse, for Windows programming with graphic output, it is essential to have acess to win32 API. I know this question might seem silly, but still please, help me, I ask for study porposes. Thanks.
