  • Java on Ubuntu server 12.04?

    - by Sean Dunwoody
    I'm a little confused at the moment. My back story in short, is that I'm trying to set up a Minecraft server on an Ubuntu server I've recently set up, obviously to do this I needed Java, but after googling for a short while I wasn't entirely sure whether it is possible (or legal?) to do so in Ubuntu 12.04 due to licensing type issues - so I installed open JDK instead which appears not to work properly with the Minecraft server software (I half expected this) I'm now considering uninstalling open JDK and instead trying to get proper Java on there instead, my question is, is this possible? Is it Legal? And if so how do I go about doing it? Because I'm finding it very difficult to find any instructions on how to do so for 12.04 . . .

  • What are common patterns for handling possible pluralization in message properties?

    - by C. Ross
    Obviously users like to see text properly pluralized, and pluralization schemes vary in the various written languages one may encounter. When internationalizing an app, what pattern(s) are useful for handling messages with possible pluralization? What about messages with multiple possible pluralization? For example: "N review(s):" One pattern would be reviews.title.singular="{0} review:" reviews.title.singular="{0} reviews:" And this may not support all languages. Or a more complicated case: "Found M question(s) with N comment(s)." This would be difficult to support in English?

  • Contiguous Time Periods

    It is always more efficient to maintain referential integrity by using constraints rather than triggers. Sometimes it isn't obvious how to do this. Until a recent idea by Alex Kuznetsov, the history table presented problems for checking data that were difficult to solve with constraints. Joe Celko explains.

  • Steps to manage a large project [closed]

    - by l46kok
    Software development is an area where parallel development to its fullest form is very difficult to achieve, although you could get reasonably close with the right design. This is especially true for game development. That being said, if you are designing a game from scratch from engine to front end, what steps should be taken in order? How would you efficiently manage your project and your team? I'm asking because several people and I are interested in working on a relatively large project for learning purposes. Initially, we were going to use a proprietary engine like Unity, but since we wanted to learn how the engine works, we're going to start from bottom. I'd appreciate any suggestions that you guys can provide me.

  • Sites with overlapping code-bases. Developing multiple sites with little changes

    - by Web Developer
    I have to develop 3 different sites video.com for hosting video audio.com for hosting audio docs.com for hosting docs. domain names for example only Almost 80% of the functionality is the same for all the three, with remaining 20% being completely different features... How do I handle this? How does sites like SO handle this? I am developing this in YII framework and was thinking of having these different features as modules but in this case the menu/code links in html code can become difficult.

  • htaccess 301 redirect help needed

    - by John
    Due to some issues in my site many pages are visible as duplicate using : www.example.com/page.html?task=view but it's content is exactly same as www.example.com/page.html. One way is to use http 301 redirect from www.example.com/page.html?task=view to www.example.com/page.html when anybody fetches page with arguments. But links like www.example.com/page.html?task=view will remain visible to outside world. Another way is canonicalization which I don't want to use as it is difficult to insert the tag in Joomla CMS. I want to hide www.example.com/page.html?task=view from external world. Is it possible to change the url from www.example.com/page.html?task=view to www.example.com/page.html ? I mean if there is href link of www.example.com/page.html?task=view in my web page, it should be visible to external world as without any arguments. This is different from using 301 to convert externally accessed page : www.example.com/page.html?task=view to without using arguments in .htaccess.

  • Is it possible for a good programmer to have never used version control?

    - by lortabac
    I am looking for an expert programmer to help solve a difficult situation. The interviews so far have been surprisingly disappointing. The best candidate so far is a very experienced programmer who has never used version control software. The problem in itself might not be too serious because it is something which can be learned in a short time. But there is a deeper aspect, which worries me: How is it possible to actively develop software for 10-15 years without ever needing version control? Is the fact itself of not looking for a solution to the problem of tracking changes a sign of a wrong attitude to programming?

  • Scammers on the lose pretending to be Microsoft

    - by John Paul Cook
    Minutes ago I received a phone call that the caller ID listed as “Out of area”, which I knew was a bad sign. It was difficult to understand the caller because of his very thick accent. He told me that he was from Microsoft and that my computer was throwing a large number of errors and he was calling to help me. He directed me to use Windows R to open a run dialog box, type eventvwr and then look at the Event Viewer. Within Event Viewer, he instructed me to open Custom Views and then open Administrative...(read more)

  • How would you approach developers you don't already know as a developer to offer them a position? [closed]

    - by Kit Sunde
    We've been trying to find a second developer for the company and have posted job ads online but so far there have been no developers that have been interested, and only a single one that has some experience in Python (that failed a fairly basic practical). It seems like the it's really difficult to find decent people here in Singapore, even reasonable juniors that you can teach. I'm contemplating whether I should go reach out directly to people on Stack Overflow and github and in the hopes that they are interested. I'm thinking I would message the person with only a few sentences, stating the they seems capable from their online presence and that I'd like to work with them. Is this kosher? I know I dislike recruiters and unsolicited mail just as much as the next guy.

  • What is this called?

    - by robertlewis2001
    I'm hoping there's a book or something out there for me to get... If I have a class that has Collection as an instance variable, what is that method of coding called? A design pattern? If so, where can I find more information on it? As I've been working with this mentor, he's really helped me understand my programming weakness and that weakness is thinking in terms of collections or relationships between objects. It just seems so difficult for me right now and I need to read to become smarter. My mentor is a great guy, but he gets frustrated when I start asking lots of questions, so I'm starting to feel like I need to learn more on my own. public class Evaluation { private List<Criterion> criterion = null; public Evaluation() { criterion = new List<Criterion>(); } }

  • What are some methods for pulling information and interacting with flash games?

    - by Xploit
    In general, how should I approach interacting with a flash game pragmatically? The flash game is online and I would like to be able to pull information from the game, make computations, and send the appropriate keystrokes back to the flash game? I'm having difficult deciding how to begin. Any specific libraries or languages that you feel would be best for accomplishing this task? I would like it to be as fast as possible. Are there ways of doing this without taking screen shots and simulating keyboard presses?

  • Considerations for changing URL path

    - by Mandar
    I am having an e-commerce site and current URL structure is like this: www.example.com/category1 [Category landing page] www.example.com/category1/sub-category [sub-category listing page] www.example.com/category1/sub-category/product-name [Product Details page] I am finding it difficult to identify from the URLs whether the URL is category landing page or a listing page or a product details page (primarily in Google Analytics). To solve this problem, I am thinking of adding qualifiers in the URL as follows: www.example.com/category1/cat-land [Category landing page] www.example.com/category1/sub-category/cat-list [sub-category listing page] www.example.com/category1/sub-category/product-name/prod-details [Product Details page] Original URLs would be redirected to new URLs using 301 permanent redirect. Would this have any negative effect on existing SEO and Google ranking?

  • What are some concise and comprehensive introductory guide to unit testing for a self-taught programmer [closed]

    - by Superbest
    I don't have much formal training in programming and I have learned most things by looking up solutions on the internet to practical problems I have. There are some areas which I think would be valuable to learn, but which ended up both being difficult to learn and easy to avoid learning for a self-taught programmer. Unit testing is one of them. Specifically, I am interested in tests in and for C#/.NET applications using Microsoft.VisualStudio.TestTools in Visual Studio 2010 and/or 2012, but I really want a good introduction to the principles so language and IDE shouldn't matter much. At this time I'm interested in relatively trivial tests for small or medium sized programs (development time of weeks or months and mostly just myself developing). I don't necessarily intend to do test-driven development (I am aware that some say unit testing alone is supposed to be for developing features in TDD, and not an assurance that there are no bugs in the software, but unit testing is often the only kind of testing for which I have resources). I have found this tutorial which I feel gave me a decent idea of what unit tests and TDD looks like, but in trying to apply these ideas to my own projects, I often get confused by questions I can't answer and don't know how to answer, such as: What parts of my application and what sorts of things aren't necessarily worth testing? How fine grained should my tests be? Should they test every method and property separately, or work with a larger scope? What is a good naming convention for test methods? (since apparently the name of the method is the only way I will be able to tell from a glance at the test results table what works in my program and what doesn't) Is it bad to have many asserts in one test method? Since apparently VS2012 reports only that "an Assert.IsTrue failed within method MyTestMethod", and if MyTestMethod has 10 Assert.IsTrue statements, it will be irritating to figure out why a test is failing. If a lot of the functionality deals with writing and reading data to/from the disk in a not-exactly trivial fashion, how do I test that? If I provide a bunch of files as input by placing them in the program's directory, do I have to copy those files to the test project's bin/Debug folder now? If my program works with a large body of data and execution takes minutes or more, should my tests have it do the whole use all of the real data, a subset of it, or simulated data? If latter, how do I decide on the subset or how to simulate? Closely related to the previous point, if a class is such that its main operation happens in a state that is arrived to by the program after some involved operations (say, a class makes calculations on data derived from a few thousands of lines of code analyzing some raw data) how do I test just that class without inevitably ending up testing that class and all the other code that brings it to that state along with it? In general, what kind of approach should I use for test initialization? (hopefully that is the correct term, I mean preparing classes for testing by filling them in with appropriate data) How do I deal with private members? Do I just suck it up and assume that "not public = shouldn't be tested"? I have seen people suggest using private accessors and reflection, but these feel like clumsy and unsuited for regular use. Are these even good ideas? Is there anything like design patterns concerning testing specifically? I guess the main themes in what I'd like to learn more about are, (1) what are the overarching principles that should be followed (or at least considered) in every testing effort and (2) what are popular rules of thumb for writing tests. For example, at one point I recall hearing from someone that if a method is longer than 200 lines, it should be refactored - not a universally correct rule, but it has been quite helpful since I'd otherwise happily put hundreds of lines in single methods and then wonder why my code is so hard to read. Similarly I've found ReSharpers suggestions on member naming style and other things to be quite helpful in keeping my codebases sane. I see many resources both online and in print that talk about testing in the context of large applications (years of work, 10s of people or more). However, because I've never worked on such large projects, this context is very unfamiliar to me and makes the material difficult to follow and relate to my real world problems. Speaking of software development in general, advice given with the assumptions of large projects isn't always straightforward to apply to my own, smaller endeavors. Summary So my question is: What are some resources to learn about unit testing, for a hobbyist, self-taught programmer without much formal training? Ideally, I'm looking for a short and simple "bible of unit testing" which I can commit to memory, and then apply systematically by repeatedly asking myself "is this test following the bible of testing closely enough?" and then amending discrepancies if it doesn't.

  • Handling (many) multiple projects in Git in an enterprise environment

    - by Michael K
    One of the advantages of older version control systems such as CVS and SVN in enterprise development is that anyone can connect to source control and see all the projects that the company has. This can make it easier to get a high level view of what kid of development is happening outside your sprint and also keeps everything in one place and easy to find. However, distributed version control systems (Git, specifically) use the repository as their base unit. They work best with one project (or several closely related projects) per repository. This makes repository management more difficult in most enterprise environments where it is not unusual to have more than 25-50 projects to support. As far as I have been able to determine, you have to keep a list somewhere else of all the repos you have. There is software available, like GitHub, that help, but that still is an extra step beyond a single connection string and listing the contents of the repository. What is the best way to deal with the complexity of multiple repositories?

  • How to use database to generate multiple folder content page? [migrated]

    - by VenomVipes
    Scenario :I am trying to build a Mobile Entertainment Portal. It will enable users to download Music & Movies to their Cell Phones... Problem Exp : Suppose I upload 100 folders of Songs, each folder is for one Album. I want a way to generate a page with all the folders name (Album Name) in it. If user click on the page, they should be taken to a page where they get list of all songs in the album. Clicking on any song name will let them download it. Can it be done anyway or will I have to manually design each of the 3 pages for each album. If I do that, its time consuming and also will be difficult to change anything like footer, header...

  • cursor jumps when moving (and some other times)

    - by nyne
    i updated to 12.10 beta 1 when it was released (coming from 12.04 fresh install, i skipped the alpha releases of 12.10) since then i've done all the usual updates but ive had an issue with my cursor jumping. it does not jump when typing, i've done a lot of searching and cant find an answer, it tends to happen most when i move the cursor the jump is maybe 15-20 pixels down and to the right it seems like a display issue because if i hover over a link or the x to close a window the cursor will settle in it's down/right position, but the whatever im hovering over will still act as if that's where the mouse is, and clicking still works on the item. so the mouse is actually in its original location, but it's displaying offset and flickering back and forth from its down/right position and its correct position this makes use very difficult because the mouse is never displayed where it actually is and i have to estimate my clicks any ideas?

  • Is there an open source solution that I can host on a web server that will allow users to anonymously upload a file to me?

    - by mjn12
    I'm looking for some kind of web application I can host on my Linux web server that will allow users to upload files of arbitrary size to me from their browser without requiring them to log in. Ideally this application would allow me to generate a link to my website that allowed for a one-time use upload. It might contain a unique, random key that was only good for that session. I could email them the link, they click it and are taken to a page where they can upload their file to me. I'm mainly targeting friends and family that need to send me files that are too large for email. I don't want to require them to install anything (dropbox), sign up and log in, etc. I'm definitely not teaching them to use FTP. This wouldn't be a difficult project for me to roll on my own but I'd like to take something off the shelf if it is possible. Does anything like this exist that my google-foo isn't turning up?

  • Microsoft Releasing Windows 8 in Late October

    The one thing Microsoft did not give was the exact date in October that this latest operating system would become available. But that may be difficult to predict. Brandon LeBlanc, Microsoft communications manager, stated only that Windows 8 is on track for a release to manufacturers (RTM) in August. The company, on average, produces a new version of Windows every three years; the last one to come out was Windows 7, back in October of 2009. The operating system will enjoy a widespread release, coming out in 109 languages across 231 markets throughout the world. It will be used not only in PCs...

  • How to add SMS text messaging functionality to my website?

    - by jessegavin
    I want to add the ability to send reminders to people via email and SMS for specific events that they have signed up for on a web application that I am building. The email part is not difficult, but I am wondering where to find a good solution for sending SMS messages. It would also be a plus if this solution allowed two-way SMS communication with my web application so that people would be able to reply with a CONFIRM or CANCEL type of a message. Has anyone implemented something like this? Does anyone know of good tools out there? EDIT: I am realizing that this is more of a "lots of ways to skin this cat" type of question and so I changed it to community wiki.

  • HTML Manifest for Content Folios

    - by Kyle Hatlestad
    I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. [Read More]

  • How to access UbuntOne when it asks for default keyring which has never been set?

    - by obu-tim
    I am trying to set up UbuntuOne on a new computer and after I enter the email and password, it asks for the keyring 'default'. I don't know what it is and I never set it. Makes it difficult to enter so it seems to be a counterproductive security default. I understand that if autologin is set the keyring is called. I tried setting the main user to need a password but if I reboot it doesn't ask for the password so it sort of autoboots still. So How do I set the keyring default password? If I can't set it I can't install UbuntOne

  • Is the UX affected negatively by fully cacheable pages?

    - by ChocoDeveloper
    I want to have fully cacheable pages in my websites, but one cannot do that if they contain user-specific data, like the userbar or things in the UI that can change depending on the permissions the user has. So I was thinking whether it was possible to pull everything that is user-specific via ajax, and update the UI accordingly. But I'm worried that this might be annoying for the user, and also it might be difficult to develop. What do you think? Is there a pattern or something I can follow to deal with this?

  • Is programming or computer science in general, all about algorithms?

    - by wakandan
    As a grad student, I find it more and more common for prestigious companies (like Google, Facebook, Microsoft,...) to put algorithm questions in their test and interviews. A few startups I applied to also asked about algorithms. I wonder if algorithms fluency is the most important thing for software developer in those companies? If the answer being yes, what are the best method or resources for one to learn & practice about algorithms effectively? I can't seem to get interested in solving seemingly too complicated problems found in most textbook or websites. Though easily understand basic algorithms (like quicksort, bubblesort,...), I find it immensely difficult to remember and reuse them later. Thanks. P/S: If you ask me what I like, it's building good softwares to solve users' problems innovatively. I suppose that does not necessarily mean the software has to be very complicated.

  • How to find classes that use certain DB tables

    - by Songo
    Problem: I'm asked to prepare a document where all our DB tables are listed and I'm supposed to list all Controllers that uses these DB tables for read and another list for Controllers that do write operations. Ex: +------------------------------------------+------------+ | DB table | tbl_Orders | +------------------------------------------+------------+ |Controllers that perform read operations | ?? | +------------------------------------------+------------+ |Controllers that perform write operations | ?? | +------------------------------------------+------------+ We are trying to write some documentation for a legacy system built using Zend framework. The code is scattered everywhere. There is code in the Controllers, in the models and even in the views. The application uses PROPEL as an ORM. What makes this really difficult is that the Controller may not be directly calling the table, but it may be instantiating a model class that calls that table. Is there an educated way to approach this crazy task? Note: Searching for the table name won't provide a solution because if a model uses that table I wouldn't know which Controller is using that model.
