  • What notes should I be taking, if any, at the beginning of a project?

    - by Justin R.
    I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

  • Sending an SMS myself

    - by user246114
    Hi, I'm taking shots in the dark here. I'd like to create a web service where eventually I send an SMS by using my own hardware. I'm not sure what I need in order to send an SMS myself. I don't want to use any of the existing SMS send services out there, I need to be able to send these SMS myself. It looks like there's one opensource project in particular that deals with this, "Kannel": http://www.kannel.org/ what I don't understand is, do I need to get a GSM modem to be able to send SMS? Do SMS gateways (like Kannel) eventually need to get to a GSM modem to send messages, or is there some other hardware you need to be able to actually send the messages? Thanks

  • What are some practical uses of generating all permutations of a list, such as ['a', 'b', 'c'] ?

    - by Jian Lin
    I was asked by somebody in an interview for web front end job, to write a function that generates all permutation of a string, such as "abc" (or consider it ['a', 'b', 'c']). so the expected result from the function, when given ['a', 'b', 'c'], is abc acb bac bca cab cba Actually in my past 20 years of career, I have never needed to do something like that, especially when doing front end work for web programming. What are some practical use of this problem nowadays, in web programming, front end or back end, I wonder? As a side note, I kind of feel that expecting a result in 3 minutes might be "either he gets it or he doesn't", especially I was thinking of doing it by a procedural, non-recursive way at first. After the interview, I spent another 10 minutes and thought of how to do it using recursion, but expecting it to be solved within 3 minutes... may not be a good test of how qualified he is, especially for front end work.

  • OpenGL embedded in gtk has colour badly displayed

    - by Sardathrion
    Note that this is a re-write now that I have more clues as to where the problem could be... I am creating a GTK GUI which contains two embedded OpenGL displays. Both use the same shader code (complied once for each). On my normal hardware, this works fine. On a virtual machine running on the same hardware, I get horrible colours -- see images. I suspect that the shader code is at fault -- certainly dropping a simpler shader does make the problem moot. However, I do need both diffuse and spot lights in my shader thus making it non-trivial. Anyone has seen this before?

  • Is Android reference at android.com good enough

    - by the100rabh
    Hi, I am a C++ developer, but have a fair idea of Java as I learnt it in college 5years ago. I have been trying to learn programming for android. But instead of rushing to buy books, I have tried to read through the Android Dev Guide and learn from there making use of the sample applications. Thats besides SO ofcourse. I am trying to make some apps based on ideas I have. So my question is, Is it suitable or possible to learn android programming this way. Or is there something that I will be missing in all this.

  • Ideas for using R to create a T-shirt design (for useR 2010) ?

    - by Tal Galili
    There is now a competition for creating a T-shirt design for useR2010. Someone proposed the idea to use R for creating the T-shirt image. Which leads me to my questions: What type of images do you think might be fitting for this? How would you suggest to use R to create the images ? Would anyone here want to have a go at it? (p.s: I understand this is not a pure "programming" question. Yet it involves R programming, the understanding of R aesthetics, and some caring for the R community. I also understand I am at the risk of annoying people here with this question, so in case that happens - I deeply apologies! My only justification is that I am acting in good faith and in the purpose of having nice things for R users to enjoy, while learning something in the process) Related thread I once opened: http://stackoverflow.com/questions/2162131/how-can-i-learn-to-create-beautiful-infographics-with-connection-to-my-r-knowled

  • How have your coding values changed since graduating?

    - by Matt
    We all walked out of school with the stars in our eyes and little experience in "real-world" programming. How have your opinions on programming as a craft changed since you've gained more experience away from academia? I've become more and more about design a la McConnell : wide use of encapsulation, quality code that gives you warm fuzzy feelings when you read it, maintainability over execution performance, etc..., whereas many of my co-workers have followed a different path of fewer middlemen layers getting in the way, code that is right out in the open and easier to locate, even if harder to read, and performance-centric designs. What have you learned about the craft of software design which has changed the way you approach coding since leaving the academic world?

  • Eliminating false dependencies

    - by Klaus
    Hi all, I have a quite general question regarding false dependencies. As the name implies, those or no real dependencies and can be elimianated. I am aware of techniqes called register renaming that eliminate such dependencies at a hardware level. Of course I could eliminate those already at a "higher" level when writing assembler code that avoids false dependencies. But now I am wondering if also the compiler provides support to keep the number of false dependencies low or does it more rely on the hardware to eliminate those? Thanks

  • Copying a 2D non-space array to another

    - by Jay
    I'm a total programming newb who started learning java programming this sem at uni. I'm up to a step where i need to copy some elements from one method to another. This program i'm creating is called an L_Game. The question I'm stuck is: the project(Slide other) method should take another slide as a parameter, and copy each non-space cell from this slide into the other slide (i.e. like a projector projecting slides onto a screen. I previously made a constructor with the parameter cells in it and believe i copied it to the project(Slide other) method. But i'm not sure what to do to copy each "non-space cell" With the "for" method or the "if" method? If my question isn't typed correctly or have information missing, please let me know. Any help will be appreciated. (I obviously have no idea with what i'm doing...)

  • How to write configurable Embedded C code which can run on multihardware platform

    - by Adnan
    Hello all , What are the techniques used to write an embedded C software which has multi features. Features can be configurable for multi-hardware platform. I have developed a firmware based on a RTOS for ARM7. Now i want to make it a baseline firmware which can be used with similar, more or less features (configurable) on different microcontrollers, like MSP, or AVR etc. Being more specific, if i want to change different features of firmware for one hardware and others for the second. What technique should i adopt and is there any study material available. Regards

  • wxWidgets - Add items to sizer via DLL

    - by intl
    I have a GUI set up with wxWidgets (C++, MSVC) and part of the functionality is to add elements to the GUI via DLL's. Essentially, I would be passing in a sizer to the DLL which will in turn add the elements based on what is in the DLL. Could someone just point me in the right direction on how to get the DLL set up? I have looked, but don't see anything that's similar to what I'm looking for. The programming of the elements is fine with me, I just need to understand how to structure the DLL programming. Help appreciated.

  • When did the idea of macros (user-defined code transformation) appear?

    - by Jay
    I have read McCarthy's 1960 paper on LISP and found no reference to anything that's similar to user-defined macros or normal order evaluation. I was wondering when marcos first appeared in programming language history (and also in Lisp history): When was the idea of user-defined code transformation (before interpretation or compilation) first described (theoretically)? What was the first programming language implementation to have Lisp-like macros (by "Lisp-like" I mean "using a readable Turing-complete language to do code-transformation")? (including non-Lisps -- Forth for example is quite old, but I'm not sure if the first Forth implementation already had "IMMEDIATE") What was the first Lisp dialect to have macros? Thank you!

  • write cache and write sequence order

    - by excanoe
    ok, here i have some weird question: let say we have some binary file (.log), and sequence of write operations, for example log1, log2, log3 and each has some block size n (raw data). question: can I be sure that log1,log2 and log3 sequences can be written in the correct order in ONE file, even if i have few cache levels (disk hardware and os level)? update very interested in what will be with records order (not with records) if we have software or hardware failure (reboot or another reason). update there can be some percent of write failures, but main question is: will write order stay correct?

  • Learning C++ from AS3

    - by grey
    I'm a decent AS3 programmer. I work in games, and that is my reason for programming. While there is much I can accomplish with Adobe AIR, my understanding at this point is that learning C++ is probably a good direction to take. I would learn a lot of valuable lower level programming if I needed it down the road, and I would have an easier time learning other C oriented languages. I see a lot of information for people looking to learn AS3 who know C++, but not the other way around. Why C++? Cross platform compatibility is important to me, so I'm not particularly interested in C# or Objective-C at this junction. I'm also aware of HaXe, and while I love the concept, after doing some research I'm worried about investing a lot of time into something so recent with limited learning resources and documentation. I'm looking for advice and resources (books, articles) related to this topic. Thanks in advance!

  • pass by reference but reference to data and not to variable

    - by dorelal
    This is psesudo code. In what programming language this is possible ? def lab(input) input = ['90'] end x = ['80'] lab(x) puts x #=> value of x has changed from ['80'] to ['90] I have written this in ruby but in ruby I get the final x value of 80 because ruby is pass-by-reference. However what is passed is the reference to the data held by x and not pointer to x itself same is true in JavaScript. So I am wondering if there is any programming language where the following is true.

  • error msg in avr studio4

    - by shubhang
    i have recently purchased an AVR USB programmer from robokits.co.in, was trying to program atmeg8 using AVR studio4 and i get the following when i click on the program options: a problem occurred when executing the command. make sure u are using the correct programming method. current mode is ISP verify that the device is placed in the correct socket, and that the ISP cable is connected properly.check that the programming frequency specified in the main page is well below 1/4th of the clock frequency of the device. i have tried all that i could think of, i have checked the connections and the freq is below 1/4th of the device. but that doesn't solve this problem i have made the circuit for blinking LEDs program please help me out see the image for details thanking you

  • What's the deal with all of the abstract stuff?

    - by JustVenting
    I see a lot of talk about MVVM, MVC, Design Patterns etc... You know, some guy has a blog, and he spent the last six months learning about one these things and desiging a program centered around that concept and then he goes on and on about it like its better than sliced bread. I read all of this crap and I wonder, whatever happened to simple logical programming? Not self-absorbed huge frameworks of design patterns and mvc and whatever else you can think of... just simple linear programming, perhaps a few classes to encapsulate things here and there.

  • Web and stand-alone apps development tendency

    - by Narek
    There is a strong tendency of making web apps and even seems that very soon a lot of features will be available online so that for every day use people will have all necessary software free online and they will not need to install any software locally. Only specific (professional) tools that usually people don’t use at home will not be available as a web app. So my question, how do you imagine selling software that was necessary for everyday use and was not free (seems they can't make money any more by selling their product – no need of those products). And what disadvantages have web apps, that is to say, what is bad to use software online compared with having the same software locally (please list)? Please do not consider this question not connected with programming, as I really would like to have a little statistics from professional programmers who are aware from nowday’s tendency of software and programming. Thanks.

  • Is Learning the win32 API Worthwhile?

    - by kronoz
    I was certain that somebody would have specifically asked this question, but from what I can see no-one has (there's been a question about learning win32 but that doesn't cover whether it's worthwhile doing so). I am very interested in gaining a deeper understanding of all the systems I use (I mostly program in C#, at least professionally), so I wondered, very simply - is learning win32 worthwhile, or is it overkill? Am I wasting my time? Is the knowledge I'd gain worth the effort? Similar / related questions on StackOverflow: Does it still make sense to learn low level WinAPI programming? How relevant is Win32 programming to modern professionals?

  • C# similar technologies and books in Java

    - by MigNix
    Hi, I know this can look like dublicate of other discussions and I have already reviewed them, but they are different. I want to learn Java and I want to know are there any books similar to those that I have seen for C#. Here is the list: C# 4.0 in a Nutshell: The Definitive Reference Probably Java in a Nutshell :) Professional C# 4.0 and .NET 4 Pro C# 2010 and the .NET 4 Platform Accelerated C# 2010 Programming WCF Services Essential Windows Communication Foundation (WCF): For .NET Framework 3.5 C# in Depth: What you need to master C# 2 and 3 CLR via C# Professional ADO.NET 3.5 with LINQ and the Entity Framework Professional Enterprise .NET Framework Design Guidelines: Conventions, Idioms, and Patterns for Reusable .NET Libraries Mainly I am interested in Java 6 and want to know about JVM , Cuncurency, Data access and distributed application technologies. I have seen there are some books on JVM like Inside the Java 2 Virtual Machine also some free books on official web site. Also I found concurrent programming in Java. But may be you can suggest any others. Thank you
