  • Unable to detect windows hard drive while running Ubuntu 12.04 from USB

    - by eapen jacob
    I am completely new to Ubuntu. I experimented with Ubuntu 12.04 by running it from a USB drive, in-order to recover files from my hard disc. History: My laptop is an IBM R60 running windows 7. Suddenly it gave me an error stating "error 2100 - Hard drive initialization error". I have read all the forums and most of them suggested that I remove and replace my HDD and that did not work. And one site suggested to try using Ubuntu to recover files. I booted my system from USB, and once Ubuntu came up, I choose "Try Ubuntu". It came up fine and I was able to surf ,and do other things, etc. I was unable to to access my files which are on the hard disc and "Attached Devices" is grayed out. 1- Is there any way to gain access to my hard disc to recover the files? How do I navigate to search for my files. 2- Is it just simply not possible if the hard disc themselves are not working? Is that why I`m unable to find the drives. I know its a very novice question, but hoping someone would help me out. Thank you, Eapen

  • Why is not there a python compiler to native machine's code?

    - by user2986898
    As I understand, the cause of the speed difference between compiled languages and python is, that the first compiles code all way to the native machine's code, whereas python compiles to python bytecode, to be interpreted by the PVM. I see that this way python codes can be used on multiple operation system (at least in most cases), however I do not understand, why is not there an additional (and optional) compiler for python, which compiles the same way as traditional compilers. This would leave to the programmer to chose, which is more important to them; multiplatform executability or performance on native machine. In general; why are not there any languages which could be behave both as compiled and interpreted?

  • Can manager classes be a sign of bad architecture?

    - by Paul
    Lately I've begun to think that having lots of manager classes in your design is a bad thing. The idea hasn't matured enough for me to make a compelling argument, but here's a few general points: I found it's a lot harder for me to understand systems that rely heavily on "managers". This is because, in addition to the actual program components, you also have to understand how and why the manager is used. Managers, a lot of the time, seem to be used to alleviate a problem with the design, like when the programmer couldn't find a way to make the program Just WorkTM and had to rely on manager classes to make everything operate correctly. Of course, mangers can be good. An obvious example is an EventManager, one of my all time favorite constructs. :P My point is that managers seem to be overused a lot of the time, and for no good reason other than mask a problem with the program architecture. Are manager classes really a sign of bad architecture?

  • The Obscured C Competition is Back!

    - by TATWORTH
    The Obscure C competition is back at http://www.ioccc.org/ The Competition is open to the 12/Jan/2012. The aim of the competition is: To write the most Obscure/Obfuscated C program under the rules at http://www.ioccc.org/2011/rules.txt. To show the importance of programming style, in an ironic way. To stress C compilers with unusual code. To illustrate some of the subtleties of the C language. To provide a safe forum for poor C code. :-) Even if you are not a C programmer, it is worth looking at some past entries at: http://en.wikipedia.org/wiki/International_Obfuscated_C_Code_Contest

  • Switching domains in one's career?

    - by rocknroll
    I have been a C++,Qt programmer for the last 3.5 years and have hit a plateau in terms of doing something new. Work has been repetitive and routine. I personally believe it is time to move on but off late I am getting more offers in mobile development like Android,Iphone etc. The latest offer I have is for objective-C based profile. I do not have the slightest idea about objective-C apart from that it is Object oriented C resembling C++ but not exactly a clone. Questions in my mind are --what are the pros/cons of this careers switch or for any such switch? --Is it good for one's career to change domains after sometime? --How difficult it is to get back to one's previous area of proficiency? Thanks

  • What are the different branches of Programming? [closed]

    - by clueless
    I just want a very general overview about what are the actual 'branches' of programming in the industry. What are different paths one can choose as a programmer and what are the common frameworks/languages/platforms in those paths. Currently I'm well versed with C/C++ and Python and I'm a beginner with Django. I want to know this because I can't decide what to proceed with after this, which route to take. Hope it's not a very general question. Thanks!

  • Should I be using a game engine?

    - by Kyle
    I'm an experienced programmer, but I'm completely new to making games. I'm thinking of making an iPhone game that is similar to a 2d tower defense type game. In the web programming world, it would be a big waste of time to make a website without using some sort of web framework (eg ruby on rails). Is that the same for making games? Do people mostly use some sort of framework/game engine for making a game? If so, what are the popular ones for iOS?

  • Is it worth replacing mouse by standalone trackpad for heavy code-editing? [on hold]

    - by heltonbiker
    I recently got more interested in improving my tools, workspace and worflow. The first sting came with a sore finger due to a crappy keyboard, and then after some research I fell in love with the "mechanical keyboard is what you need" doctrine, bought one (cherry MX Brown if you're curious), and am very happy with the results. Currently I am replacing my previous text editor (Geany) with Sublime Text 3, and am also very happy and feeling much more powerful and professional :) Well, but while I re-read all the ancient debates about VIM vs whatever-else, the following excerpt from a blog post got me thinking again about the mouse vs keyboard, and the "moving around from the very home row" (in VIM) versus gesturing away with the tiny and unstable mouse cursor: Reaching for a mouse may indeed slow you down, but developers are commonly on machines where the trackpad is a micro-hand movement away. Most novice programmers can click on a character on screen faster than an expert Vimmer can type 20jFp; or LkEEE or /word or any other nasty way Vimmers have to use. The point of a mouse is to make arbitrary on screen jumps efficient, and it’s very good at doing that. Don’t you ever think you can beat a mouse. Well, although there is some bitterness in this statement, it makes a lot of sense, and EVEN MORE if you consider your direct input to be a TRACKPAD conveniently placed in front of your spacebar (which oddly is where I like to put my mouse, rotated 90° ccw, due to a serious tendonitis in my right shoulder, already healed, but you knod...). So, the question is: Has anyone replaced mouse by a standalone trackpad, to work in code editing in a desktop machine (that is, with a sandalone keyboard)? Was it worth the change?

  • What are famous windows programming framework in work field?

    - by Moon
    Hi, I am a php programmer. Ever since I started working in php industry, companies I worked with used zend framework, codeigniter, and cake php. So...in windows programming world, what are equivalent to zend framework, codeigniter, and cake php? The reason I am asking this question is because I am about to start windows programming. I am not asking for a certain language. I would like to know many frameworks as possible. p.s: someone please add 'framework' and 'popular' tags for me...

  • Where do you get new software ideas from? [closed]

    - by Cape Cod Gunny
    The world of software creation is very competitive. I've heard it said to be successful you need to be the first one with the idea. Everyone knows how Bill Gates created IBM DOS on one machine while simultaneously building MS-DOS on another machine (and we all know how that turned out). In order to be the first to come up with a new software product, where do you go looking for fresh ideas? Update 06/26/13: Reworded this question in an attempt to get it reopened. Bill Gates developed MS-DOS at the same time he was hired to develop IBM DOS. As a programming community, we would all gain by understanding how to think up great ideas for software. As programmer we tend to get stuck in our thinking... it's refreshing to hear how fellow programmers busted out and came up with their ideas. It's not very likely that we will have an MS-DOS opportunity like Bill Gates. Please vote to reopen.

  • Add & Show data in Java ArrayList [closed]

    - by Kaidul Islam Sazal
    I have a class inside a main class : static class Graph{ static int u, v, cost; } I have instantiated an arraylist of the class: static List<Graph> g = new ArrayList<Graph>(); And I insert several values into the arraylist like this: Scanner input = new Scanner(System.in); for (int i = 0; i < edge_no; i++) { Graph e = new Graph(); e.u = input.nextInt(); e.v = input.nextInt(); e.cost = input.nextInt(); g.add(e); } And I print it like this: for (int i = 0; i < edge_no; i++) { System.out.println(g.get(i).u + " " + g.get(i).v + " " + g.get(i).cost); } But the problem is that, when I print it, only the last value is shown all the time.It seems that, all the previous values are over-written with it. Input : 1 2 5 1 3 8 2 3 9 Output: 2 3 9 2 3 9 2 3 9 Expected output is just like the input.But I can't fix the problem as I am novice in java.

  • anyone familiar with these analytic questions?

    - by Moon
    So...my recruiter just called me to confirm my interview on Thurs. He also mentioned that I am going to be asked to answer for two analytic questions. He gave me a little bit about those questions. There are eight balls. One of them is defective. There are three incandescent light bulbs inside a room, but switches are placed outside. These are all he said. I think that these are not completed question. Anyone knows what questions these are?? Does my question belong to programmer.stackexchange.com? I thought it would because it is related to interview questions.

  • Where can I find good (well organized) examples of game code?

    - by smasher
    Where can I find good (well organized) examples of game code? I'm hoping that I can pick up some organizational tips. Most examples in books are too short and leave out lots of detail for the sake of brevity. I'm particularly interested on how to group your variables and methods so that another programmer would know where to look in the code. For example initializers at the top, then methods that take input, then methods that update views. I don't care about a particular language, as long as its OOP. I looked at the Quake 2 and 3 sources, but they're straight C and not much help for getting tips on organizing your objects. So, have you seen some good source? Any pointers to code that makes you say "wow, that's well organized" would be great.

  • How to get out of supporting deadend sales pitches?

    - by JoseK
    As part of being a programmer, you often are asked to provide estimates/ make slideware / do technical demos for Sales teams to present to end-clients. Sometimes we go along for the 'technical' discussions or 'strategic capability planning' or some similar mumbo-jumbo. Sometimes, you kind of know which ones are totally going to fail and are not worth pursuing but the Sales guys present fake optimism and extract 'few more slides' out of you or the 'last conference call'. These don't lead to anywhere and are just a waste of time from other tasks for the week. My question is how do you get out of these situations without coming across as non-cooperative. Updated after Kate Gregory's answer: The problem is related to projects we know are doomed (from the technical feedback we've received) But Sales ain't convinced since they've just had a call higher up the management chain - so it's definitely going ahead !

  • VPN server on Windows Server 2008 for a small office

    - by cmbrnt
    I'm going to refurbish the IT-infrastructure for a small organization with one single office, and I'm not sure what VPN server to use. In your opinion, would the built-in Windows Server 2008 VPN server suffice or are there any specific problems with it as opposed to, for example, OpenVPN? I'd rather run a Windows native VPN server, but if there are few (preferably free) good alternatives, I could install VMware ESXi and virtualize both Windows and an OpenVPN-server. By the way, because of a low budget this office runs a solution with only one physical server. Any advice would be great to help me grasp this field of which I'm quite a novice. Thank you!

  • 3D mobile game development [on hold]

    - by SCM
    I am not a developer or programmer and, I am planning an educative project that will involve having students to develop a cross-platform, 3D mobile game, similar to the SimCity concept. I need to write a project requirement and I'd like to pick someone's brain to understand what's involved in developing such a project: -Is it realistic to have one or two students to do it? and along their other modules at uni? - How much time can it take to develop from scratch? - what are the different skills required? Thank you All SCM

  • Create subdomains via C-Panel or via domain registrar?

    - by cybergeek654
    I am a novice, so excuse me if it sounds dummy. I read a few similar questions on this topic here but they did not answer my question. I have a personal website, hosted with C-panel control panel. Via C-panel I can easily create new subdomains and I do not need to apply any DNS settings or so. And the subdomian is good to go immediately and are working fine. I have unlimited subdomains option. When I check my DNS management control panel in my domain registrar's site, there is no record associated with my subdomains. Now I want to buy a new domain name from 1and1, and have it as an add-on domain in my prevouse host. 1and1 say they only allow 5 subdomains. What does this mean? Can not I create unlimited subdomains under my new domain name, just as I do for my old domain? How does C-panel create and manage subdomains that there is nothing about it in my DNS control panel? Thanks for your help

  • How to balance programming projects between feasibility and usefulness

    - by tyjkenn
    I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

  • What is important when starting GUI programming, and pick from widget libraries [closed]

    - by jokester
    I have been a CLI programmer, and recently I found it will be a plus to learn GUI programming. In past, my experience and knowlegde was a bit messy. So you may imagine many detour were there in my way, that is true. And I want to avoid getting lost again if possible. When googling about existing GUI framework, I found it is hard to choose my start point from GTK, QT, and lot of less famous peers. What are important factors when you guys are facing that problem? Will it be a good idea to pick a small enough library and feel its fundamental ideas?

  • Web App for storing and organize programming information?

    - by Fabzter
    So, I've found myself, after several years of coding (I consider myself a coder, rather than a programmer) full of links and loose snippets and coding tips, all dispersed across the web. In such way it is barely usable, even when every bit is important or interesting. I thought of simply storing the links in delicious or something alike, but it's not really the links I want to keep, I just need the succinth info. So I was thinking to use some web app, something like a wiki, maybe much more simple, so I could access it though my mobile if I need it. I could code it, but as I stated it before, I'm more of a code monkey, and I'm sure my solution would be far from decent... Can anyone give me recommendations on this?

  • How To Deliberately Hide Bugs In Code (for use in a Novel I'm writing) [closed]

    - by Dennis Murphy
    I'm writing a novel in which an evil programmer wants to include subtle errors in his code that are likely to go unnoticed by his supervisor during a code review and unlikely to be caught by a compiler, yet cause damage at possibly random times when the program is executed by an end-user. I only need a couple of examples, which may be exotic but which have to be easily explainable to non-technical readers. Procedural or object-oriented examples would be equally helpful. (It's been a VERY long time since I've written any code.) Thanks for your help.

  • Is "convention over configuration" not violating basic programming principles?

    - by Geerten
    I was looking at the WPF MVVM framework Caliburn.Micro and read that a lot of standard things are based on naming conventions. For example, automatic binding of properties in the View to properties in the ViewModel. Although this seems to be convenient (removes some boilerplate code), my first instinct reaction is that it isn't completely obvious to a new programmer that will read this code. In other words, the functionality of the application is not completely explained by its own code, but also by the documentation of the framework. EDIT: So this approach is called convention over configuration. Since I could not find any questions concerning this, I altered my question: My question is: Is convention over configuration a correct way of simplifying things, or is it violating some programming principles (and if so, which ones)?

  • How to pause and resume a game in XNA using the same key?

    - by user13095
    I'm attempting to implement a really simple game state system, this is my first game - trying to make a Tetris clone. I'd consider myself a novice programmer at best. I've been testing it out by drawing different textures to the screen depending on the current state. The 'Not Playing' state seems to work fine, I press Space and it changes to 'Playing', but when I press 'P' to pause or resume the game nothing happens. I tried checking current and previous keyboard states thinking it was happening to fast for me to see, but again nothing seemed to happen. If I change either the pause or resume, so they're both different, it works as intended. I'm clearly missing something obvious, or completely lacking some know-how in regards to how update and/or the keyboard states work. Here's what I have in my Update method at the moment: protected override void Update(GameTime gameTime) { KeyboardState CurrentKeyboardState = Keyboard.GetState(); // Allows the game to exit if (CurrentKeyboardState.IsKeyDown(Keys.Escape)) this.Exit(); // TODO: Add your update logic here if (CurrentGameState == GameStates.NotPlaying) { if (CurrentKeyboardState.IsKeyDown(Keys.Space)) CurrentGameState = GameStates.Playing; } if (CurrentGameState == GameStates.Playing) { if (CurrentKeyboardState.IsKeyDown(Keys.P)) CurrentGameState = GameStates.Paused; } if (CurrentGameState == GameStates.Paused) { if (CurrentKeyboardState.IsKeyDown(Keys.P)) CurrentGameState = GameStates.Playing; } base.Update(gameTime); }

  • From Java to Javascript? [duplicate]

    - by theGreenCabbage
    This question already has an answer here: Are there any OO-principles that are practically applicable for Javascript? 2 answers I am primarily a Java programmer. Because of its OO principles and the general paradigm of Java programming, like wrapping things in static variables, and having things return specific types, heavily aids me in "visualizing" a program. Instead of thinking of a big program, I can, instead, focus on smaller organized parts of my eventual program, and add functionality and build up from there. Thus, I have trouble programming in other languages. Or at least, I have not been able to program in the same ability as I do in Java compared to other languages. I know Javascript has OO principles, so I'd like to learn this language in a OO-based like I would program with Java. Is this possible?

  • Master Typing Productivity when Programming/SysAdmin [closed]

    - by Hartator
    I try to learn how to type fast and have managed to learn a lot. I am quite good at typing english text now. I do a lot of programmation though and if QWERTY seems fitted for english text, it doesn't seem fitted to type Ruby, Python, Javascript, Command Line or C++... I have read plenty of articles and if I respect their guidelines/tips, I am using a lot my right pinky specially to type []{}|\;:'"/?=+ enter delete. As you can see this symbols are the ones which are the most used when you are programming and we are using only one weak finger to reach them. Am I learning wrong? Is there is a way to be more productive? (I don't really want to switch to DVORAK) Have you some experiences/tips to share regarding this issue?
