  • Templates "untitled" after file extension problem in 12.04

    - by wpinacz
    I've been using "Templates" folder in my home directory to create new files (.doc .odt .xls), the problem is that, when I right-click in my Desktop (or any other folder), and go into "Create New Document" and choose "Microsoft Word Document", I get a new file with name called "Microsoft Word Document.doc untitled". I want to remove "untitled" from filename so it's called "Microsoft Word Document.doc" or even change it so it would be "untitled.doc". Is there any way to do it? Searched other forums and can't find solution.

  • Is there any officially recognized, specific determinants that make a language programming/scripting?

    - by Dan
    I remember when I was first learning web-based programming everyone was intent on JavaScript not being a "programming language," but rather a scripting language; I have not heard that argument in quite a while now. I hear a lot of languages, like perl for example, referred to at different times as both a scripting and programming language. I know that a scripting language is less capable than a programming language, but where exactly does the line lie? Citation would be appreciated.

  • Why an SEO Article Service Should Not Bite the Language That Bites Back

    As a professional SEO article service I have witnessed a great deal of confusion, misunderstanding and downright idiocy when it comes to writing articles for the web, or content for websites. Creating effective SEO articles or search engine optimized content is not easy - yet so many people seem quite happy to take people's money despite, for example, having only a passing appreciation of the English language!

  • Techniques for Working Without a Debugger [closed]

    - by ashes999
    Possible Duplicate: How to effectively do manual debugging? Programming in a debugger is ideal. When I say a debugger, I mean something that will allow you to: Pause execution in the middle of some code (like a VM) Inspect variable values Optionally set variable values and call methods Unfortunately, we're not always blessed to work in environments that have debuggers. This can be for reasons such as: Debugger is too too too slow (Flash circa Flash 8) Interpreted language (Ruby, PHP) Scripting language (eg. inside RPG Maker XP) My question is, what is an effective way to debug without a debugger? The old method of "interleave code with print statements" is time-consuming and not sufficient.

  • The Cobra Programming Language

    There are suddenly a number of strong alternatives to C# or VB. F#, IronPython and Iron Ruby are now joined by an open-source alternative called Cobra. Phil is taken by surprise at a language that is so intuitive to use that it is almost like pseudocode.

  • Involving kids into programing - which language? [closed]

    - by boj
    Possible Duplicate: What are some good tools for introducing kids to programming? Long-long time ago I had a great book by Frank DaCosta about writing adventure games in Basic, it had a great influence on me. I would like to show the world of programming to my child too but I have two problems: I can not found books like DaCosta's (but we can replace it with our fantasy so not a big deal) Which programming language should I use? Small Basic?

  • Interface extension

    - by user877329
    Suppose that I have an input stream interface, which defines a method for reading data. I also have a seekable interface which defines a method for seeking. A natural way of defining a input file is then to implement both input stream and seekable. I want to construct a data decoder from the input stream interface so I can read data from a file or from another stream. The problem is that I also want to implement seek functionality to the data decoder, since I want to be able to step individual records not raw bytes. This is not possible if I only provide an input stream, which does not have the bytewise seek method. Should I skip the seekable interface and add the seek method to input stream instead and force all streams to at least leave it as a nop.

  • Sharepoint Guidance Logger: usage, setup and extension

    - by spano
    Introduction Log records are essential to any application for troubleshooting problems. When beginning a new Sharepoint project, one of the first needs is to have a core logging component that can be used throughout the application code. In this post I will talk about the logging solution that we are using (based on the Patterns & Practices Sharepoint Logger ), how to set it up, configure and read logs. SharePoint 2010 includes enhanced functionality for logging and tracing. You can now throttle...(read more)

  • How common are circular references? Would reference-counting GC work just fine?

    - by user9521
    How common are circular references? The less common they are, the fewer hard cases you have if you are writing in a language with only reference counting-GC. Are there any cases where it wouldn't work well to make one of the references a "weak" reference so that reference counting still works? It seems like you should be able to have a language only use reference counting and weak references and have things work just fine most of the time, with the goal of efficiency. You could also have tools to help you detect memory leaks caused by circular references. Thoughts, anyone? It seems that Python uses references counting (I don't know if it uses a tracing collector occasionally or not for sure) and I know that Vala uses reference counting with weak references; I know that it's been done before, but how well would it work?

  • Creating Visual Studio Extension Files (VSIX) for Template Deployment

    While working on some plugins for the new Seesmic Desktop PlatformI got sick of copying and pasting some boiler plate code over and over. I had created some helper templates for myself so that I could say FileNew Seesmic Desktop Plugin and get everything I needed initially. This weekend I had some time and formalized those templates into an easy-to-use installer for anyone to consume. NOTE: It is likely that Seesmic themselves will create developer project/item templatesthese were for my own...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • category theory based language

    - by pagoda_5b
    It may sound naive, but is there any programming language, or research thereof, based entirely on category theory? I mean this as opposed to embedding CT concepts as an additional feature (like for Haskell or scala). Would it be too abstract or too complex as an approach, or are there any known reasons that makes it impossible or impractical? I have only a relative understanding of the theory as related to programming, so please give me some explanation if the question doesn't makes sense at all

  • 14.04 default locales

    - by Seán Ó Séaghdha
    After a new install of 14.04 I have quite a few extra locales/languages. Is this normal? I installed using English (GB) I think since en_AU isn't an option. At some point apt offered a list of unused files which I removed. Now when I open Language Support it warns me that "Language support is not installed completely" and offers to reinstall this list... kde-l10n-zhcn thunderbird-locale-en-gb thunderbird-locale-es libreoffice-l10n-en-gb libreoffice-help-es libreoffice-help-en-gb wspanish thunderbird-locale-zh-cn myspell-es ibus-sunpinyin mythes-en-au kde-l10n-es libreoffice-l10n-zh-cn fonts-arphic-uming ibus-table-wubi thunderbird-locale-es-es thunderbird-locale-zh-hans libreoffice-l10n-en-za thunderbird-locale-es-ar hunspell-en-ca libreoffice-l10n-es libreoffice-help-zh-cn kde-l10n-engb fonts-arphic-ukai So are Spanish and Chinese installed by default in all installations now? Why do I need Canadian English spellchecking installed?

  • Creating a new variable versus assigning an existing one

    - by rwallace
    Which is more common, creating a new variable versus assigning an existing variable (field, array element etc - anything that syntactically uses the assignment operator)? The reason I ask is that I'm designing a new language, and wondering which of these two operations should get the shorter syntax. It's not intended to be a pure functional language, or the question wouldn't arise, so I'd ideally like to count usage across large existing code bases in procedural and object-oriented languages like C, C++ and Java, though as far as I can see there isn't an easy way to do this automatically, and going by memory and eyeball, neither is obviously more common than the other.

  • Is it relevant to warn about truncating real constants to 32 bits?

    - by zneak
    I'm toying around with LLVM and looking at what it would take to make yet another strongly-typed language, and now that I'm around the syntax, I've noticed that it seems to be a pet peeve of strongly typed language to warn people that their constants won't fit inside a float: // both in Java and C# float foo = 3.2; // error: implicitly truncating a double into a float // or something along these lines Why doesn't this work in Java and C#? I know it's easy to add the f after the 3.2, but is it really doing anything useful? Must I really be that aware that I'm using single-precision reals instead of double-precision reals? Maybe I'm just missing something (which, basically, is why I'm asking). Note that float foo = [const] is not the same thing as float foo = [double variable], where requiring the cast seems normal to me.

  • What programming language(s) could I develop this app with for an iPhone

    - by Keon Davies
    The app I'm thinking of making would be little similar to fruit ninja. The app/ game would involve different types of animals flying straight at and you have to choose the right item to catch the animal before he gets to you. For example to capture a fish you would have to select the net and then click on the fish to capture it. Also I would like to have a leader board too. Which programming language(s) could I use to develop what I just described?

  • A completely free and open programming language

    - by XGouchet
    With Oracle vs Google trial, it seems that Java is not entirely Open and free (as free software) as I expected. Although there exists completely free/open JVM, it's hard to know what is a copyright infringement with Java, and what is not. So I'd like to know if there is a completely Open and free language with open and free IDE (Eclipse-like) out there, Object Oriented if possible, and able to make window-based applications for the main OSs (Linux, Mac, Windows).

  • Converting lib from other language to python and Rights issue

    - by Arruda
    If I take a program, and basically translate its source from some language to python, with some small changes, can I do a entirely my new lib or I have to make a "version" of the old one? would this be a copy of the first or a new lib based in the ideas of the first? OBS: Consider the original lib is using Apache License v2 Not sure if well explained, but I can't see for now how to make it more clear.
