  • Installation hangs at "Retrieving file 43 of 105" Virtualbox OS X 10.7 Host Ubuntu 12.04 x86 guest

    - by goodcop
    This is my second attempt at installing Ubuntu. In my first attempt, I selected "download updates" and "install third-party components"; in my second attempt, I deselected both. Still experiencing the same problem. In my first attempt at installing Ubuntu, after the installation stuck at "Retrieving file 43 of 105", I selected "skip" and the installation completed. After I started to run the OS, I received a notification that language support was incomplete. When I tried to update it, the Ubuntu Software Centre updating process hung on "waiting for jockey-backend to exit", seemingly indefinitely. At that point, I decided to reinstall the system (since the whole process is only supposed to take 45 minutes or less), but, as I mentioned above my results were the same. I'm new to Ubuntu. Any advice? Where are the files (including file 43) being retrieved from? Online or from the ubuntu installation iso? I have searched many forums for an answer to this problem, and have seen others with the same issue but I haven't found a solution. Thanks.

  • Why do some programmers think there is a contrast between theory and practice?

    - by Giorgio
    Comparing software engineering with civil engineering, I was surprised to observe a different way of thinking: any civil engineer knows that if you want to build a small hut in the garden you can just get the materials and go build it whereas if you want to build a 10-storey house you need to do quite some maths to be sure that it won't fall apart. In contrast, speaking with some programmers or reading blogs or forums I often find a wide-spread opinion that can be formulated more or less as follows: theory and formal methods are for mathematicians / scientists while programming is more about getting things done. What is normally implied here is that programming is something very practical and that even though formal methods, mathematics, algorithm theory, clean / coherent programming languages, etc, may be interesting topics, they are often not needed if all one wants is to get things done. According to my experience, I would say that while you do not need much theory to put together a 100-line script (the hut), in order to develop a complex application (the 10-storey building) you need a structured design, well-defined methods, a good programming language, good text books where you can look up algorithms, etc. So IMO (the right amount of) theory is one of the tools for getting things done. So my question is why do some programmers think that there is a contrast between theory (formal methods) and practice (getting things done)? Is software engineering (building software) perceived by many as easy compared to, say, civil engineering (building houses)? Or are these two disciplines really different (apart from mission-critical software, software failure is much more acceptable than building failure)?

  • Upgrading Visual Studio 2010

    - by Martin Hinshelwood
    I have been running Visual Studio 2010 as my main development studio on my development computer since the RC was released. I need to upgrade that to the RTM, but first I need to remove it. Microsoft have done a lot of work to make this easy, and it works. Its as easy as uninstalling from the control panel. I have had may previous versions of Visual Studio 2010 on this same computer with no need to rebuild to remove all the bits. Figure: Run the uninstall from the control panel to remove Visual Studio 2010 RC Figure: The uninstall removes everything for you.  Figure: A green tick means the everything went OK. If you get a red cross, try installing the RTM anyway and it should warn you with what was not uninstalled properly and you can remove it manually.   Once you have VS2010 RC uninstalled installing should be a breeze. The install for 2010 is much faster than 2008. Which could take all day, and then some on slower computers. This takes around 20 minutes even on my small laptop. I always do a full install as although I have to do c# I sometimes get to use a proper programming language VB.NET. Seriously, there is nothing worse than trying to open a project and the other developer has used something you don't have. Its not their fault. Its yours! Save yourself the angst and install Fully, its only 5.9GB. Figure: I always select all of the options.   Now go forth and develop! Preferably in VB.NET…   Technorati Tags: Visual Studio,VS2010,VS 2010

  • game multiplayer service development

    - by nomad
    I'm currently working on a multiplayer game. I've looked at a number of multiplayer services(player.io, playphone, gamespy, and others) but nothing really hits the mark. They are missing features, lack platform support or cost too much. What I'm looking for is a simple poor man's version of steam or xbox live. Not the game marketplace side of those two but the multiplayer services. User accounts, profiles, presence info, friends, game stats, invites, on/offline messaging. Basically I'm looking for a unified multiplayer platform for all my games across devices. Since I can't find what I'm planning to roll my own piece by piece. I plan to save on server resources by making most of the communication p2p. Things like game data and voice chat can be handled between peers and the server keeps track of user presence and only send updates when needed or requested. I know this runs the risk of cheating but that isn't a concern right now. I plan to run this on a Amazon ec2 micro server for development then move to a small to large instance when finished. I figure user accounts would be the simplest to start with. Users can create accounts online or using in game dialog, login/out, change profile info. The user can access this info online or in game. I will need user authentication and secure communication between server and client. I figure all info will be stored in a database but I dont know how it can be stored securely and accessed from webserver and game services. I would appreciate and links to tutorials, info or advice anyone could provide to get me started. Any programming language is fine but I plan to use c# on the server and c/c++ on devices. I would like to get started right away but I'm in no hurry to get it finished just yet. If you know of a service that already fits my requirements please let me know.

  • Meaningful concise method naming guidelines

    - by Sam
    Recently I started releasing an open source project, while I was the only user of the library I did not care about the names, but know I want to assign clever names to each methods to make it easier to learn, but I also need to use concise names so they are easy to write as well. I was thinking about some guidelines about the naming, I am aware of lots of guidelines that only care about letters casing or some simple notes. Here, I am looking after guidelines for meaningful concise naming. For example, this could be part of the guidelines I am looking after: Use Add when an existing item is going to be added to a target, Use Create when a new item is being created and added to a target. Use Remove when an existing item is going to be removed from a target, Use delete when an item is going to be removed permanently. Pair AddXXX methods with RemoveXXX and Pair CreateXXX methods with DeleteXXX methods, but do not mix them. The above guidance may be intuitive for native English speakers, but for me that English is my second language I need to be told about things like this.

  • The PATRIOT Act and how it relates to the Internet

    The subject of the Internet and anonymity is a very sticky situation for me because I primarily develop web applications for a living.  As a part of my job I have to track users as they enter, navigate and leave specific applications. The level of tracking depends on where the user goes within a website.  The basic information that I capture includes the user’s IP address, browser type, operating system, the date/time they entered the site and the URL from which the user was referred to the website. In addition to the custom logging that is placed on the website, web servers also have methods of logging built-in as well. Web server logging allows companies to have a central repository to store all user activity across the entire server. Not to mention that they can also create a central repository that allows multiple servers to store log files in one location. This allows users to be tracked across multiple servers as they browse website located on a specific collection of servers that host multiple websites. All this being said there are methods to attempt to protect your privacy by using proxy servers and increasing your browser security levels, but that will only limit the amount of logging not eliminate it. I have to agree with Traynor when he states that the PATRIOT Act eviscerates the constitutional protections of anonymous communication on the Internet. Therefore, given the recent passage and implementation of the PATRIOT Act, the constitutional guarantees of the right to anonymity have been severely compromised. I think that the PATRIOT Act is a direct violation of our first amendment rights because it allows for the government to directly monitor any and all activity on the internet including communications, usage, and transactions that can occur.  This opens the door to scrutiny and persecution of individuals who are not in line with the government’s beliefs and actions. If England had this type of monitoring capabilities during the revolutionary war, I believe it would have been almost impossible to succeed from England.

  • How would I implement this application idea?

    - by Mike Wills
    I am a D&D gamer and a developer that has mostly worked with ASP.NET applications professionally. I have written some chat bots in Node.js and I have only played a little with PHP but wrote nothing serious. I have had inspiration to create a site that allows a person to keep track of characters (aka the character sheet). I am thinking of using this as a learning opportunity to learn noSQL and to write a full javascript front-end. I want this application to save the value as I change it. So if I edit the armor class, it is saved immediately instead of waiting until I hit the submit button. I think that will make it easier to use while gaming and not losing anything because I forgot to save the change. I have never done anything like this. How do you implement this style of application? Is there a tutorial or howto to get me on the right path? While I would really like to use ASP.NET but I don't have a Windows server to publish on (and I really can't afford to pay for a service). What language that runs on Linux would work well for this type of application? Note: I feel noSQL would work in this case because of the sheer number of tables required to create something like this in SQL.

  • What do you think of this iterator syntax?

    - by ChaosPandion
    I've been working on an ECMAScript dialect for quite some time now and have reached a point where I am comfortable adding new language features. I would love to hear some thoughts and suggestions on the syntax. Example iterator Numbers { yield 1; yield 2; yield 3; if (true) { yield break; } yield continue iterator { yield 4; yield 5; yield 6; }; } Syntax IteratorDeclaration:     iterator  Identifier  {  IteratorBody  } IteratorExpression:     iterator  Identifieropt  {  IteratorBody  } IteratorBody:     IteratorStatementsopt IteratorStatements:     IteratorStatement IteratorStatementsopt IteratorStatement:     Statement but not one of BreakStatement ContinueStatement ReturnStatement     YieldStatement     YieldBreakStatement     YieldContinueStatement YieldStatement:     yield  Expression  ; YieldBreakStatement:     yield  break  ; YieldContinueStatement:     yield  continue  Expression  ;

  • So are we ever getting the technological singularity

    - by jsoldi
    I´m still waiting for an AI robot that will pass the Turing test. I keep going back to http://www.a-i.com/ and nothing. I don´t know much about AI but, did anyone ever tried to make a genetic algorithm whose evolution algorithm itself evolves? Or how about one whose algorithm that makes the genetic algorithm evolve, evolves? Or one whose genetic algorithm that makes the genetic algorithm that makes the genetic algorithm evolve, evolves? Or how about an algorithm that abstracts all this into a potentially infinitely deep tree of genetic evolution algorithms? Aren´t we just failing as programmers? And I don´t think we can blame the processors speed. If you make and application that simulates consciousness you will get a Nobel prize no matter how many hours it takes to respond to your questions. But nobody did it. It almost reminds me to Randi´s $1000000 paranormal challenge. As I keep going back to AI chat bots, they keep getting better at changing the subject on a way that seems natural. But if I tell them something like "if 'x' is 2 then whats two times 'x'?" then they don't have a clue what I'm talking about. And I don't think they need a whole human brain simulation to be able to answer to something like that. They don't need feelings or perception. This is just language and logics. I don't think my perception of the color red gives me the ability to understand that if 'x' is 2 then two times 'x' is 4. I'm sure we are just missing some elemental principle we cannot grasp because it's probably stuck behind our eyes. What do you think?

  • Design for XML mapping scenarios between two different systems [on hold]

    - by deepak_prn
    Mapping XML fields between two systems is a mundane routine in integration scenarios. I am trying to make the design documents look better and provide clear understanding to the developers especially when we do not use XSLT or any other IDE such as jDeveloper or eclipse plugins. I want it to be a high level design but at the same time talk in developer's language. So that there is no requirements that slip under the crack. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with mapping XML fields between two systems? (without XSLT being involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I am trying to find out if there is a better way to represent XML mapping in your design documents. The widely accepted and used method seems to be using a simple table such as in the picture to illustrate the mapping. I am wondering if there are alternate ways/ tools to represent such as in Altova:

  • Adding Suggestions to the SharePoint 2010 Search Programatically

    - by Ricardo Peres
    There are numerous pages that show how to do this with PowerShell, but I found none on how to do it with plain old C#, so here it goes! To abbreviate, I wanted to have SharePoint suggest the site collection user’s names after the first letters are filled in a search site’s search box. Here’s how I did it: 1: //get the Search Service Application (replace with your own name) 2: SearchServiceApplication searchApp = farm.Services.GetValue<SearchQueryAndSiteSettingsService>().Applications.GetValue<SearchServiceApplication>("Search Service Application") as SearchServiceApplication; 3: 4: Ranking ranking = new Ranking(searchApp); 5:  6: //replace EN-US with your language of choice 7: LanguageResourcePhraseList suggestions = ranking.LanguageResources["EN-US"].QuerySuggestionsAlwaysSuggestList; 8:  9: foreach (SPUser user in rootWeb.Users) 10: { 11: suggestions.AddPhrase(user.Name, String.Empty); 12: } 13:  14: //get the job that processes suggestions and run it 15: SPJobDefinition job = SPFarm.Local.Services.OfType<SearchService>().SelectMany(x => x.JobDefinitions).Where(x => x.Name == "Prepare query suggestions").Single(); 16: job.RunNow(); You may do this, for example, on a feature. Of course, feel free to change users for something else, all suggestions are treated as pure text.

  • What is the best practice for when to check if something needs to be done?

    - by changokun
    Let's say I have a function that does x. I pass it a variable, and if the variable is not null, it does some action. And I have an array of variables and I'm going to run this function on each one. Inside the function, it seems like a good practice is to check if the argument is null before proceeding. A null argument is not an error, it just causes an early return. I could loop through the array and pass each value to the function, and the function will work great. Is there any value to checking if the var is null and only calling the function if it is not null during the loop? This doubles up on the checking for null, but: Is there any gained value? Is there any gain on not calling a function? Any readability gain on the loop in the parent code? For the sake of my question, let's assume that checking for null will always be the case. I can see how checking for some object property might change over time, which makes the first check a bad idea. Pseudo code example: for(thing in array) { x(thing) } Versus: for(thing in array) { if(thing not null) x(thing) } If there are language-specific concerns, I'm a web developer working in PHP and JavaScript.

  • TDD - Outside In vs Inside Out

    - by Songo
    What is the difference between building an application Outside In vs building it Inside Out using TDD? These are the books I read about TDD and unit testing: Test Driven Development: By Example Test-Driven Development: A Practical Guide: A Practical Guide Real-World Solutions for Developing High-Quality PHP Frameworks and Applications Test-Driven Development in Microsoft .NET xUnit Test Patterns: Refactoring Test Code The Art of Unit Testing: With Examples in .Net Growing Object-Oriented Software, Guided by Tests---This one was really hard to understand since JAVA isn't my primary language :) Almost all of them explained TDD basics and unit testing in general, but with little mention of the different ways the application can be constructed. Another thing I noticed is that most of these books (if not all) ignore the design phase when writing the application. They focus more on writing the test cases quickly and letting the design emerge by itself. However, I came across a paragraph in xUnit Test Patterns that discussed the ways people approach TDD. There are 2 schools out there Outside In vs Inside Out. Sadly the book doesn't elaborate more on this point. I wish to know what is the main difference between these 2 cases. When should I use each one of them? To a TDD beginner which one is easier to grasp? What is the drawbacks of each method? Is there any materials out there that discuss this topic specifically?

  • Low hanging fruit where "a sufficiently smart compiler" is needed to get us back to Moore's Law?

    - by jamie
    Paul Graham argues that: It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU. ... The most ambitious is to try to do it automatically: to write a compiler that will parallelize our code for us. There's a name for this compiler, the sufficiently smart compiler, and it is a byword for impossibility. But is it really impossible? Can someone provide a concrete example where a paralellizing compiler would solve a pain point? Web-apps don't appear to be a problem: just run a bunch of Node processes. Real-time raytracing isn't a problem: the programmers are writing multi-threaded, SIMD assembly language quite happily (indeed, some might complain if we make it easier!). The holy grail is to be able to accelerate any program, be it MySQL, Garage Band, or Quicken. I'm looking for a middle ground: is there a real-world problem that you have experienced where a "smart-enough" compiler would have provided a real benefit, i.e that someone would pay for?

  • C++ 'using': Should I use it or should I avoid it?

Also: should I prefer ::std:: over std::? using namespace std; pair<string::const_iterator, string::const_iterator> f(const string &s) { return make_pair(s.begin(), s.end()); } or std::pair<std::string::const_iterator, std::string::const_iterator> f(const std::string &s) { return std::make_pair(s.begin(), s.end()); } or using std::pair; using std::string; pair<string::const_iterator, string::const_iterator> f(const string &s) { return make_pair(s.begin(), s.end()); } or std::pair<std::string::const_iterator, std::string::const_iterator> f(const std::string &s) { using std::make_pair; return make_pair(s.begin(), s.end()); } or std::pair<std::string::const_iterator, std::string::const_iterator> f(const std::string &s) { using namespace std; return make_pair(s.begin(), s.end()); } or something else?

  • Constructs for wrapping a hardware state machine

    - by Henry Gomersall
    I am using a piece of hardware with a well defined C API. The hardware is stateful, with the relevant API calls needing to be in the correct order for the hardware to work properly. The API calls themselves will always return, passing back a flag that advises whether the call was successful, or if not, why not. The hardware will not be left in some ill defined state. In effect, the API calls advise indirectly of the current state of the hardware if the state is not correct to perform a given operation. It seems to be a pretty common hardware API style. My question is this: Is there a well established design pattern for wrapping such a hardware state machine in a high level language, such that consistency is maintained? My development is in Python. I ideally wish the hardware state machine to be abstracted to a much simpler state machine and wrapped in an object that represents the hardware. I'm not sure what should happen if an attempt is made to create multiple objects representing the same piece of hardware. I apologies for the slight vagueness, I'm not very knowledgeable in this area and so am fishing for assistance of the description as well!

  • How to organize a programming course?

    - by Bogdan Gavril
    I've been given the task to train our manual testers to become developers in test (write test automation!). some have basic programing knowledge (either dabbling in PHP or reading stuff) and some who have no experience. Note that I do have teaching experience, but with real students, not employees, and one concern is that they will not put extra hours except the 20% management gave them for the transition. Language to be taught and used: C# We have 8 hours per week to do this and should decide if they will make it in 2 months. I am thinking of a combined approach: use a manual such as Head First C# (although I'm not happy with the labs, they're mostly games and I don't want to add UI complexities) have them read from the manual do labs with them, solving more and more difficult problems and explain the theoretical stuff as well have them do a bigger project towards the end Some questions: do you have a better suggestion as far as manuals go? do you have a better aproach? Focus less on labs? what kind of assesments should I use and how often? should I let them do a bigger project (bank system or small game) and how much time should I invest in that? ideeas on labs? other resources ? Any other tips would be most welcomed! Thanks!

  • Fastest way to group units that can see each other?

    - by mac
    In the 2D game I'm working with, the game engine is able to give me, for each unit, the list of other units that are in its view range. I would like to know if there is an established algorithm to sort the units in groups, where each group would be defined by all those units which are "connected" to each other (even through others). An example might help understand the question better (E=enemy, O=own unit). First the data that I would get from the game engine: E1 can see E2, E3, O5 E2 can see E1 E3 can see E1 E4 can see O5 E5 can see O2 E6 can see E7, O9, O1 E7 can see E6 O1 can see E6 O2 can see O5, E5 O5 can see E1, E4, O2 O9 can see E6 Then I should compute the groups as follow: G1 = E1, E2, E3, E4, E5, O2, O5 G2 = O1, O9, E6, E7 It can be safely assumed that there is a transitive property for the field of view: [if A sees B, then B sees A]. Just to clarify: I already wrote a naïve implementation that loops on each row of the game engine info, but from the look of it, it seems a problem general enough for it to have been studied in depth and have various established algorithms (maybe passing through some tree-like structure?). My problem is that I couldn't find a way to describe my problem that returned useful google hits. Thank you in advance for your help!
