  • How to fix missing menus in non ubuntu maverick apps

    - by piedro
    Hi! There's a bug with the menue of filezilla: When opening filezilla there is no menue list. Very inconvenient because you can't open the "settings"-dialog. There are several workarounds that I tried - none of them really work. change theme while filezilla is running, menue reapperars. Once you close and reopen it the menue is gone again. add "export UBUNTU_MENUPROXY=0" " to .bash.rc or just call it before starting filezilla. Doesn't have any effect for me - menue still missing. tried "sudo apt-get remove appmenu-gtk" cause it's obviously to do with unity but the funny thing is even this method has bo effect at all! How can I fix this? How to do the troubleshooting? thx fior reading, p.

  • Data Synchronization in mobile apps - multiple devices, multiple users

    - by ProgrammerNewbie
    I'm looking into building my first mobile app. One of the core features of the application is that multiple devices/users will have access to the same data -- and all of them will have CRUD rights. I believe the architecture should involve a central server where all the data is stored. The devices will use an API to interact with the server to perform its data operations (e.g. adding a record, editing a record, deleting a record). I imagine a scenario where synchronizing the data will become a problem. Assume the application should work when it is not connected to the Internet, and thus cannot communicate with this central server. So: User A is offline and edits record #100 User B is offline and edits record #100 User C is offline and deletes record #100 User C goes online (presumably, record #100 should get deleted on the server) User A and B goes online, but the records they edited no longer exist All sorts of scenarios similar to the above can come up. How is this generally handled? I plan to use MySQL, but am wondering if it's not appropriate for such a problem.

  • Clicking on active apps on unity launcher stopped working

    - by Tim
    I don't know how it suddenly became this but here's what's happening right now: e.g. I have 2 firefox windows open, so I see 2 small arrows on the left side icon of the unity launcher. Before, when I click on the firefox icon, I see 2 small windows of the firefox so I can choose which one. Now it suddenly stopped working. (super+W still works though). The bug on my system applies to all progams with multiple window instances like nautilus, terminal, etc. Please help, I don't know what to do. I also have cairo dock, compiz, myunity installed in my 12.04. I tried searching online to no avail.

  • University teaches DOS-style C++, how to deal with it

    - by gaidal
    Half a year ago I had a look at available programming educations. I chose this one because unlike most of the choices: The majority of the courses seemed to be about something concrete and useful; the languages used are C++ and Java which are platform-independent; later courses include developing for mobile devices and a course on Android development, which seemed modern and relevant. Now after two introductory courses we're just starting with C++, and my programming professor seems a bit weird. He's tested us on things like "why should you use constants" and "why are globals bad" in a kind of mechanical way, without much context, before teaching actual programming. His handouts use system("pause"), system("cls"), and getch() from some conio.h that seems ancient according to what I've read. I just did a task that was about printing the "ASCII letters from 32 to 255" (huh?), with an example picture showing a table with Windows' Extended ASCII - of course I got other results for 128-255 on my Arch Linux that uses Unicode, and this isn't mentioned at all. I don't know, it just doesn't seem right... As if he is teaching programming because he has to, perhaps? Should I bring such things up? Hmm. I was looking forward to learning from someone who really knows stuff, and in an academic, rigorous way, like SICP or something. Aren't professors in programming supposed to be like that? I studied math for a while and every teacher and assistant there were really precise about what they said, but this is my second programming teacher that is sort of disappointing. Oh well. Now, question: Is this what to expect from universities or Not OK, and how do I deal with it? I have never touched the language C++ (or C) until now, and am not the right person to jump up and say "This is So Wrong!", so if I google something and find 10 people who say "xxx is blasphemy", how do I skillfully communicate this? I do think it would be better for those classmates who are total beginners not to learn bad habits (such as these vibes of total ignorance of other platforms!) during the upcoming courses, but don't want to disrespect the teacher. I don't know if it's reasonable or just cocky to bring up things like "what about other platforms?" or "but what about this article or stackoverflow answer that I read that said..." for every assignment? Or, if he keeps ignoring non-Windows-programming, should I give up and focus on my own projects or somehow argue that this really isn't OK nowadays? Are there any programming teachers out there, what do you think? By the way these are web-based courses, all interaction between teachers and students takes place in a forum. EDIT: A few answers seem to be making some incorrect assumptions, so maybe I should add a few things. I have been doing programming for fun on and off for 10 years, am pretty comfortable in 3 languages and read programming blogs et c regularly. Also, I feel kind of done being a student, having a degree in another field. I just need another, relevant diploma to work as a programmer, so I'm going back for that. Studying computer science for 5 years is not for me anymore, even though I enjoy learning and solving problems in my free time. Second, let me highlight that I don't expect it to be like the industry at all, quite the contrary. I expect it to be academic, dry and unnecessarily correct. No, it's not just math. Every professor I have had in math, or Japanese (major) or Chinese (minor) have been very very academic, discussing subtle points for hours with passion. But the courses I'm taking now and a previous one in programming don't seem serious. They neither resemble industry NOR academia. That is the problem. And it's not because I can't learn programming anyway. Third, I don't necessarily want to learn C++ or Android development, and I know I could teach myself those and anything else if I wanted to. But I am going back to school anyway, and those platform-independent languages and mobile stuff made me think that maybe they're serious about teaching something relevant here. Seems like I got this wrong, but we'll see.

  • Gnome 2 style user account settings (how to edit user accounts in Unity)

    - by user104140
    Back in Gnome 2 there was a very useful user account editing gui tool whereby I could easily add or edit a user to a group. For example, I could give a standard user access to something that they hadn't installed or don't have default access too, such as Me-TV. How do I do this in Gnome 3 / Unity? I am not allowed to create the tag "edit user accounts" or similar and there isn't anything similar existing, strangely. I'm guessing there is a totally different way to edit user accounts or no one bothers - perhaps no one shares PCs anymore.

  • Learning C++ but wanting to develop iOS Apps

    - by DiscreteGenius
    I'm a computer engineering student and taking my second programming class. I'm learning C++ using "C++ Primer Plus" 5th edition by Prata. I want to develop for iOS. I understand the main language for Xcode is Objective-C. Am I hurting myself by learning C++ before any other language (notably before my desired lang Objective-C)? There's got to be a reason the university requires C++ to learn as a basis language. Please offer any helpful guidance or how I should go about this. Thanks//

  • Enterprise Mobile Apps

    - by Sahil Malik
    SharePoint 2010 Training: more information This is one of those rare occasions when I get to write about what I’m working on in my consulting life. I’m a very lucky guy, I get to work on some very tough and challenging solutions for clients around the world. In working on such problems, I face the best challenges which help me be a better consultant. A better consultant is a better trainer. There is no substitute for real world experience. As an example, Winsmarts started working on a product with Din ERP that would bring ERP functionality into SharePoint. Not influenced by marketecture, and the only driver being success at customer, as an architect for this endeavor, I experimented with and decided against technologies such as Silverlight. We subsequently invested heavily in JavaScript when the prevalent browser was still IE6. It wasn’t easy to create an amazing amount of functionality in JavaScript, but over time we enriched the product and today we have a very compelling Read full article ....

  • css - use universal '*' selector vs. html or body selector?

    - by Michael Durrant
    Applying styles to the body tag will be applied to the whole page, so body { font-family: Verdana } will be applied to the whole page. This could also be done with * {font-family: Verdana} which would apply to all elements and so would seem to have the same effect. I understand the principle that in the first instance the style is being applied to one tag, body for the whole page whereas in the second example the font is being applied against each individual html elements. What I am asking is what is the practical difference in doing that, what are the implications and what is a reason, situation or best practice that leads to using one over another. One side-effect is certainly speed (+1 Rob). I am most interested in the actual reason to choose one over the other in terms of functionality.

  • Now you can design ADF applications that look like Fusion Apps

    - by Grant Ronald
    One possible failure point in ADF applications (and I’ve seen happen) is getting Web designers to build the UI without any knowledge of what ADF does.  The resulting design may look pretty but might be virtually impossible to implement using ADF. To help address this Oracle have released a set of Visio templates which help guide you in “Fusion”/ADF look and feel.  I’ve been lucky enough to have some of our usability teams mock up these templates for some ADF projects I’ve been working on and they are a great help in conceptualising the final applications. You can find out more about these Visio ADF templates here.

  • Should I sacrifice code succintness to ensure the narrowest variable scope? [duplicate]

    - by David Scholefield
    This question already has an answer here: Is the usage of internal scope blocks within a function bad style? 3 answers In many languages (e.g. both Perl and Java - which are the two languages I work most with) it is possible to narrow the scope of local variables by declaring them within a block. Although it adds extra code length (the opening and closing block braces), and possibly reduces readability, should I create blocks purely to narrow the scope of variables to the statements that use the variables and to uphold the principle of narrowest scope or does this sacrifice succinctness and readability just to unnecessarily uphold an agreed 'best practice' principle? I usually declare local variables to functions/methods at the start of the function to aid readability, but I could not do this, and just create blocks throughout the function and declare the variables throughout the code - within those blocks - to narrow their scope.

  • Menus not visible in some apps in Xubuntu 12.04

    - by Carl Burkart
    I've been using Ubuntu 12.04 for a few weeks and recently added the xubuntu desktop as well. I have noticed that in some applications, there is no menu present. For example, in Thunar, their is no menu (File, View, etc.), so I can't figure out how to "show hidden files." Could this be some conflict between xubuntu and unity's global menu. I want to be able to log in under either on my netbook, so uninstalling one or the other is not an option. Any ideas?

    Bhavani has some new over at java.net about the Maven Plugin for GlassFish and how it now supports the ability to deploy multiple applications. He also has a Tips, Tricks and Troubleshooting entry. Multiple deployments are done during the Maven pre-integration-test phase but with a goal-specific configuration for app, contextRoot, etc... The :run (all-in-one) execution also now supports admin and deploy goals. Note that these improvements will require a recent work-in-progress 4.0 version of GlassFish.

  • How to Use Vim-Style Keyboard Shortcuts for OS X Tab Navigation

    - by The Geek
    After switching to OS X when I got a new MacBook Air, one of the first things I needed to duplicate was my extremely customized AutoHotkey setup — the most important of which is using the J and K keys to navigate throughout tabbed windows easily. Yeah, I’m a Vim user. I’ve never been a fan of having to use CTRL + TAB to switch from one tab to the next — to start with, you have to move your hands from the home row, and it’s awkward, and why should I have to do that just because somebody decided that keyboard shortcut before tabs became popular? If you think about it, if tabbed browsers were popular back when keyboard shortcuts were being invented, they would have definitely reserved some of the good shortcuts for switching tabs. On Windows, I’ve always used an AutoHotkey script to make things the way I wanted it:  ALT + J and ALT + K for selecting previous and next tabs. Once you get used to it, it’s extremely awesome, and so much faster than using CTRL + TAB. Of course, I also hacked CTRL + T and CTRL + W into ALT + T and ALT + W so I could open new tabs and close them without moving my hands from the home row. Over on OS X, it turns out that it’s incredibly simple and easy to use CMD + J and CMD + K for next/previous tab navigation, and it works in most applications that support tabs, like Terminal, Safari, or Google Chrome.

  • The sign of a true manager is delegation (C# style)

    - by MarkPearl
    Today I thought I would write a bit about delegates in C#. Up till recently I have managed to side step any real understanding of what delegates do and why they are useful – I mean, I know roughly what they do and have used them a lot, but I have never really got down dirty with them and mucked about. Recently however with my renewed interest in Silverlight delegates came up again as a possible solution to a particular problem, and suddenly I found myself opening a bland little console application to just see exactly how far I could take delegates with my limited knowledge. So, let’s first look at the MSDN definition of delegates… A delegate declaration defines a reference type that can be used to encapsulate a method with a specific signature. A delegate instance encapsulates a static or an instance method. Delegates are roughly similar to function pointers in C++; however, delegates are type-safe and secure. Well, don’t you love MSDN for such a useful definition. I must give it credit though… later on it really explains it a bit better by saying “A delegate lets you pass a function as a parameter. The type safety of delegates requires the function you pass as a delegate to have the same signature as the delegate declaration.” A little more reading up on delegates mentions that delegates are similar to interfaces in that they enable the separation of specification and implementation. A delegate declares a single method, while an interface declares a group of methods. So enough reading - lets look at some code and see a basic example of a delegate… Let’s assume we have a console application with a simple delegate declared called AdjustValue like below… class Program { private delegate int AdjustValue(int val); static void Main(string[] args) { } } In a sense, all we have said is that we will be creating one or more methods that follow the same pattern as AdjustValue – i.e. they will take one input value of type int and return an integer. We could then expand our code to have various methods that match the structure of our delegate AdjustValue (remember the structure is int xxx (int xxx)) class Program { private delegate int AdjustValue(int val); private static int Dbl(int val) { return val * 2; } private static int AlwaysOne(int val) { return 1; } static void Main(string[] args) { } }  Above I have expanded my project to have two methods, one called Dbl and the other AlwaysOne. Dbl always returns double the input val and AlwaysOne always returns 1. I could now declare a variable and assign it to be one of those functions, like the following… class Program { private delegate int AdjustValue(int val); private static int Dbl(int val) { return val * 2; } private static int AlwaysOne(int val) { return 1; } static void Main(string[] args) { AdjustValue myDelegate; myDelegate = Dbl; Console.WriteLine(myDelegate(1).ToString()); Console.ReadLine(); } } In this instance I have declared an instance of the AdjustValue delegate called myDelegate; I have then told myDelegate to point to the method Dbl, and then called myDelegate(1). What would the result be? Yes, in this instance it would be exactly the same as me calling the following code… static void Main(string[] args) { Console.WriteLine(Dbl(1).ToString()); Console.ReadLine(); }   So why all the extra work for delegates when we could just do what we did above and call the method directly? Well… that separation of specification to implementation comes to mind. So, this all seems pretty simple. Let’s take a slightly more complicated variation to the console application. Assume that my project is the same as the one previously except that my main method is adjusted as follows… static void Main(string[] args) { AdjustValue myDelegate; myDelegate = Dbl; myDelegate = AlwaysOne; Console.WriteLine(myDelegate(1).ToString()); Console.ReadLine(); } What would happen in this scenario? Quite simply “1” would be written to the console, the reason being that myDelegate was last pointing to the AlwaysOne method before it was called. Make sense? In a way, the myDelegate is a variable method that can be swapped and changed when needed. Let’s make the code a little more confusing by using a delegate in the declaration of another delegate as shown below… class Program { private delegate int AdjustValue(InputValue val); private delegate int InputValue(); private static int Dbl(InputValue val) { return val()*2; } private static int GetInputVal() { Console.WriteLine("Enter a whole number : "); return Convert.ToInt32(Console.ReadLine()); } static void Main(string[] args) { AdjustValue myDelegate; myDelegate = Dbl; Console.WriteLine(myDelegate(GetInputVal).ToString()); Console.ReadLine(); } }   Now it gets really interesting because it looks like we have passed a method into a function in the main method by declaring… Console.WriteLine(myDelegate(GetInputVal).ToString()); So, what it the output? Well, try take a guess on what will happen – then copy the code and see if you got it right. Well that brings me to the end of this short explanation of Delegates. Hopefully it made sense!
