• How can I revive a dead translation team?

  - by Rohan

  I wish to translate ubuntu in Marathi language for which a translation team already exists. But the membership of the team is moderated and unfortunately no new member has been admitted in the team after 2010-Dec-12. All request of membership are pending after that date. I tried to contact administrator of the team at his personal email id but did not get any reply from him. As I am not a team member I can not upload my translated po file. Is there any way to take charge of the team and approve all pending request? It seems that no translation work is currently being carried out. I would like to do the work but I can not.

• How to explain OOP concepts to a non technical person?

  - by John

  I often try to avoid telling people I'm a programmer because most of the time I end up explaining to them what that really means. When I tell them I'm programming in Java they often ask general questions about the language and how it differs from x and y. I'm also not good at explaining things because 1) I don't have that much experience in the field and 2) I really hate explaining things to non-technical people. They say that you truly understand things once you explain them to someone else, in this case how would you explain OOP terminology and concepts to a non technical person?

• What is the ideal self hosted search engine?

  - by Tim Post

  I have an internal (intranet) site that is comprised of several blogs and forums, hundreds of static pages, lots of PDF files and several other document types. Its been glued together loosely over the last couple of years and now its my job to maintain it. I'm looking for a search engine that I can host myself that ideally: Allows for searching the Blog / Forum databases directly if given the database information and tables to search. Handles most text documents (PDF/DOC/ODF) Is open source, or allows access to the source code once purchased It doesn't matter to me what language or platform it is written in. Normally, I'd just use Google site search, but that's not an option for an intranet.

• ASP.NET 3.5 Functions and Subroutines

  The most basic of all ASP.NET 3.5 server side scripts that I ve covered using the Visual Basic programming language is not modular in nature. This means that an ASP.NET 3.5 server will interpret the scripts in the Visual Basic file e.g Default.aspx.vb from top to bottom. In most real-world applications that use Visual Basic in ASP.NET websites however most web developers structure their programs in modules. This article will give you information about subroutines and functions along with practical examples and their advantages....

  - by Ben Casling

  I'm having issues with my ubuntu server version 12.04 installed on a HP550 laptop, when i try sudo apt-get install <programname>, e.g apache2 it will not work, saying E: Unable to locate package apache2. I have tried to look/edit the sources. but they will not work either the gedit command is broken too, i am trying gedit /etc/apt/sources.list for those wondering, is this a case of the computer network not configured properly? it downloaded a language pack easily enough in the installation though. how do i fix this? a prompt reply would be appreciated.

• How does throwing an ArgumentNullException help?

  - by Scott Whitlock

  Let's say I have a method: public void DoSomething(ISomeInterface someObject) { if(someObject == null) throw new ArgumentNullException("someObject"); someObject.DoThisOrThat(); } I've been trained to believe that throwing the ArgumentNullException is "correct" but an "Object reference not set to an instance of an object" error means I have a bug. Why? I know that if I was caching the reference to someObject and using it later, then it's better to check for nullity when passed in, and fail early. However, if I'm dereferencing it on the next line, why are we supposed to do the check? It's going to throw an exception one way or the other. Edit: It just occurred to me... does the fear of the dereferenced null come from a language like C++ that doesn't check for you (i.e. it just tries to execute some method at memory location zero + method offset)?

• Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML - Part Two

  - by Janice J. Heiss

  A new article by Oracle’s Java Champion Jim Weaver, titled “Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML -- Part Two,” now up on otn/java, shows developers how to leverage the power of the FX Markup Language to define the UI for enterprise applications. Weaver, the author of Pro JavaFX Platform, extends the SearchDemoFXML example used in Part One to include more concepts and techniques for creating an enterprise application using FXML. Weaver concludes the article by summarizing its content, “FXML provides the ability to radically change the UI without modifying the controller. This task can be accomplished by loading different FXML documents, leveraging JavaFX cascading style sheets, and creating localized resource bundles. Named parameters can be used with these features to provide relevant information to an application at startup.” Check out the article here.

• How could there still not be a mysqldb module for Python 3?

  - by itsadok

  This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense.

• Why would one overload the && and & operator?

  - by acidzombie24

  The same question goes for | and ||. Why would one overload or 'use' the & and && operator? The only use i thought of are Bitwise Ands for int base types (but not float/decimals) using & logical short circuit for bools/functions that return bool. Using the && operator usually. I cant think of any classes that use those operators. Absolutely none. I know a class might support + (and not '-') which combine two strings together. I seen an object such as datetime overload '-' so two dates can be subtracted to make a timespan (obviously you cant add two dates) but i never seen &, &&, | and || used. Does anyone know of a use? In any language?

• If you had three months to learn one relatively new technology, which one would you choose?

  - by Ivo van der Wijk

  This question was taken from CodingHorror. On my list would be (and some actually are): Android Development (and possibly iPhone development) Go language and its concurrency NoSQL, specifically CouchDB RCTK, which happens to be my own idea / project (but all ideas have been thought or already, what matters is my implementation) But I don't think I'm being cutting-edge/thinking-outside-the-box here. What's on your list? Please don't restrict yourself to the list above - that's my list. I'm interested in hearing what others find interesting new technology.

• Should programming languages be strict or loose?

  - by Ralph

  In Python and JavaScript, semi-colons are optional. In PHP, quotes around array-keys are optional ($_GET[key] vs $_GET['key']), although if you omit them it will first look for a constant by that name. It also allows 2 different styles for blocks (colon, or brace delimited). I'm creating a programming language now, and I'm trying to decide how strict I should make it. There are a lot of cases where extra characters aren't really necessary and can be unambiguously interpreted due to priorities, but I'm wondering if I should still enforce them or not to encourage good programming habits. What do you think?

• Animation file format

  - by Paul

  I'm trying to make a simple 2D animation file format. It'll be very rudimentary: only an XML file containing some parameters (such as frame duration) and metadata, and some images, each representing a frame. I'd like to have the whole animation (frames and XML document) packed in a single file. How do you suggest I do that? What libraries are there that would allow easy access to the files inside the animation file itself? The language I'm using is C++ and the platform is Windows, but I'd rather not use a platform dependent library, if possible.

• How to set Monday as the first day of the week in GNOME Calendar applet?

  - by Jonik

  What is the recommended way to change the first day of the week to Monday (instead of Sunday, as in the screenshot below)? I couldn't find anything related in Clock Preferences, nor in System - Preferences, or System - Administration. This probably has something to do with tweaking locales, so here's (possibly relevant) output from locale: LANG=en_US.utf8 LC_CTYPE="en_US.utf8" LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8" ... LC_ALL= NB: I want to keep English as the UI language both in GNOME and on command line. Dates are currently displayed like this (e.g. ls -l): 2010-10-06 15:32, and I also want to keep that as it is.

• Is your company thinking of transitioning from java to another technology?

  - by Augusto

  As every Java developer knows, Oracle bought Sun and the future of java looks quite unclear, specially since Oracle wants to monetize the JVM. Java as a language has also been stale in the last few years, the non-inclusion of closures is one example (which might be included in java 1.8) At the same time, some new technologies such as Ruby, Scala and Groovy are being used to deliver complex sites. I'm wondering if there are companies or organizations which are talking, doing spikes or starting to use a different technology, with the idea to stop using java for green field projects, in the same way that 15 years ago companies migrated form C++, perl and other technologies to Java. I'm also interested to know what are the impressions of this happening, for example: planning to migrate to a different technology in 2 years. To be clear, I'm not asking which technology is better. I'm asking if your organization is thinking to leave Java for another technology.

• Is there a good book to grok C++?

  - by Paperflyer

  This question got me thinking. I would say I am a pretty experienced C++ programmer. I use it a lot at work, I had some courses on it at the university, I can understand most C++ code I find out there without problems. Other languages you can pretty much learn by using them. But every time I use a new C++ library or check out some new C++ code by someone I did not know before, I discover a new set of idioms C++ has to offer. Basically, this has lead me to believe that there is a lot of stuff in C++ that might be worth knowing but that is not easily discoverable. So, is there a good book for a somewhat experienced C++ programmer to step up the game? You know, to kind of 'get' that language the way you can 'get' Ruby or Objective-C, where everything just suddenly makes sense and you start instinctively knowing 'that C++ way of thing'?

• What is the difference between Static code analysis and code review?

  - by Xander

  I just wanted to know what is the difference between static code analysis and code review. How these two are done? What are the tools available today for code review/ static analysis of PHP. I also like to know about good tools for any language code review. Thanks in Advance. Xander Cage Note: I am asking this because I was not able to understand the difference. Please, I expect some answers than "I am Mr.Geek and you asked an irrelevant bla bla..... this is closed". I know this sounds mean. But I am sorry.

• php+mysql account management software?

  - by kdavis8

  I need an account system added to my website as a plugin to all of my HTML pages. The account system plugin needs to,register new users, log in current users, remove users who want to disconnect service, and manipulate all of these things via database on my web server. However, I do not know how to program in the PHP language or create and manipulate MySQL databases. I want a program that can create and manipulate the MySQL database automatically for my website and handle also PHP calls automatically. Are there any open source freeware programs out there that i can use? If so what are the names of these freeware?

• Understanding the Java Ecosystem

  - by syrion

  I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

• How can I implement an Iris Wipe effect?

  - by Vandell

  For those who doesn't know: An iris wipe is a wipe that takes the shape of a growing or shrinking circle. It has been frequently used in animated short subjects, such as those in the Looney Tunes and Merrie Melodies cartoon series, to signify the end of a story. When used in this manner, the iris wipe may be centered around a certain focal point and may be used as a device for a "parting shot" joke, a fourth wall-breaching wink by a character, or other purposes. Example from flasheff.com Your answer may or may not include a coding sample, a language agnostic explanation is considered enough.

• Need Japanese IME with Dvorak keyboard with 13.10

  - by user916792

  I recently did a fresh install of 13.10 and enabled Japanese language support. In the past this seemed to work seamlessly with my other keyboard settings when I set up my Dvorak keyboard. But this time when I toggle the IME on it uses the standard QWERTY layout. Typing English uses the Dvorak layout as I expect. This just worked for me in the past to the point where I stopped paying attention to what the underlying IME is and I don't recall any special steps other then choosing my keyboard layout and enabling Japanese. Any help would be appreciated!

• Is Java easy decompilation a factor worth considering

  - by Sandra G

  We are considering the programming language for a desktop application with extended GUI use (tables, windows) and heavy database use. We considered Java for use however the fact that it can be decompiled back very easily into source code is holding us back. There are of course many obfuscators available however they are just that: obfuscators. The only obfuscation worth doing we got was stripping function and variables names into meaningless letters and numbers so that at least stealing code and renaming it back into something meaningful is too much work and we are 100% sure it is not reversible back in any automated way. However as it concerns to protecting internals (like password hashes or sensible variables content) we found obfuscators really lacking. Is there any way to make Java applications as hard to decode as .exe counterparts? And is it a factor to consider when deciding whether to develop in Java a desktop application?
