• Unwanted systray icons

  - by Sparrowhawk4

  Is there any way to manage the icons in your systray? It's not highly important, but it annoys me having icons there that I don't want or use. It seems a little strange that it's so easy to customise just about everything else, but I can't for the life of me find a way to edit the systray. Maybe I'm just missing something? If there are specific ways of getting rid of each one, the I'd like to remove the Ubuntu One icon, the mail icon, and possibly the icon that says En1, and allows you to choose between UK and US English, unless that is important and I haven't realised it. I'm using Ubuntu 13.10.

• What are milestones for a game developer to gauge their progress?

  - by user16710

  I know actually completing a game is a massive milestone, a complete polished, holistic experience. Something that I've not yet been able to commit to. There are of course classes and degrees to earn in several fields that will help gain experience, but how would one judge their own progress and strive to progress further? The yellow brick road to "Rock Star Game Programmer" is very cloudy. At this point I think it may be closer to an ocean, drifting along until you wake up one day at your destination.

• how to focus the desktop on unity

  - by user25119

  I'm using Ubuntu 11.10 (unity 4.24.0) and I can't seem to focus the desktop. For example, if I press Mod4+D, the window I had opened stays focused, but the image is see is my wallpaper. If I minimize all windows one by one, the last window I minimize is still focused when the desktop finally appears. This means I can't add desktop icons, nor use the mouse in it. I thought about reporting a bug, but everything works fine on other computers with the latest version of Ubuntu I've used, so I'm wondering about what's happening. Before, when I pressed Mod4+D, the Unity Top Menu would say "Desktop - File Edit ..." and I could use the desktop properly. Thanks in advance!

• Managing client passwords [closed]

  - by C.Johns

  I am just starting up a small website development business and one of the issues I am having is remembering passwords and account information for clients hosting, cpanel, ftp accounts etc. I was wondering what is the most suitable system / industry standard for controlling such information? Pretty marginal on the close there... I read the FAQ and I felt list this could be a common issue for webmasters, its defiantly not a coding questions so stackoverflow is out of the question and its not a broad question its focused on one particular aspect of being a webmaster.

• Mouse running amok

  - by Norene Bult

  While using my mouse, it will all of a sudden take off and might run to calendar or/and trash. It opened calendar, then went down and opened trash up several times. It started out just doing it once in awhile with opening something and I didn't move it there. It did on it's own. Is someone controlling my computer? That's how it acts. I would like to get this straighted out. If it is my mouse just going berserk then I will install a new one. If it is something else, I'd like to know what could be causing it. I have my security set so no one can access my computer. Please can anyone help?

• What programming language matches this description? [on hold]

  - by Benubird

  I am looking for a functional language that is basically dynamic programming - i.e. one where functions are first-class objects - but where all function calls are asynchronous by default; i.e. you define function X(a,b) = (Y(a)+Z(b)), and when X() is called, it sees it is waiting for the return from two functions, runs one in the current thread, and spawns a new thread to run the other. The future is very much parallel processing; multiple cores, multiple machines, the internet of things, etc. and I was wondering if there was a language specifically designed to make this kind of parallelization easy. I currently have only used imperative languages (c, php, java, ruby, etc), so I don't know anything about what kind of functional languages are available.

• gnome-panel has multiple rows -- how to undo that?

  - by towi

  On Ubuntu 12.04 I use openbox with a single "gnome-panel" started. But after trying to configure my two screen in Xinerama mode I got additional rows of panels each time X restarted. And despite I completely reverted to my one-screen-X-config the gnome-panel displayed has 4 rows (4 at top sreen, 4 at bottom) only the outermost row has content, the other 3 are empty there is only one gnome-panel process running some widgets appear 4 times, too, although they run only once when I switch away from openbox using unity I am back to 1 row temporarily What went wrong here? How do I undo that? Things that did not help: rm -Rf .gnome2 .gconf/ .compiz-1/ pkill panel, and restarting it

• What's the reason in your mind Exception are heavily used in Managed (C# and Java) language but not in C++?

  - by ZijingWu

  AFAIK, a lot of C++ projects don't allow exceptions and deny them in coding guidelines. I have a lot of reasons, for example, Exception is hard to handle correctly if your binary needs to be compiled by separate and different compilers. But it doesn't fully convince me, there is a lot of projects which are just using one compiler. Compared to C++, Exceptions are heavily used in C# and Java and the reason can only be that Exception are not bringing enough benefit. One point is Debugbility in practice. Exception can not get the call stack in C++ code, but in C# and Java you can get the call stack from Exception, it is significant and makes debugging easier. No-CallStack is not the fault of the Exception, it is the language difference , but it impacts the Exception usage. So what's the reason that exceptions are frowned upon in c++ programs?

• What personal milestones can you use to measure growth in your programming abilities?

  - by GWLlosa

  How can you determine objectively, over time, that you are getting any better at producing code? For example, I may sit here and feel that "I know <language> now, and I use <technique> now, so I must be better." But this does not account for my own bias, or the fact that I may be getting better at a slower rate than intended, or I may actually suck at <technique> and not realize it. What methods are available for one to objectively rate one's own abilities? What about to objectively compare them to their peer groups?

• Keeping application backend and UI synchronised

  - by Deanna

  Hi all. I have an app that works with a list of objects so has one central keyed list. The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading. Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit. I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way. I can also do it lazily and repopulate the tree each time or periodically (very hackish). Does anyone have any better thoughts on how to structure this? This is being done in C# 2.0 but the concepts apply to any environment. Thanks

• Telerik OpenAccess ORM and the XML Metadata Source

  We all know that Telerik OpenAccess ORM has a completely new face with the Q1 2010 release so it is about time to start blogging about some of the features and improvements that the new Visual Designer brought along.  Today I will talk about one of the most notable changes in the new version of OpenAccess ORM and that is the XML only mapping. You all know that so far with the previous versions of the product the mapping information was defined by a mix of XML configuration files and CLR attributes. After a lot of customer feedback and thorough thought we decided to make the XML and the attributes as two separate and self-contained sources of metadata information about your model. You can choose one based on your personal preferences. I will start with a brief overview over the new XML mapping definition. Unlike previous versions, where all ...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.

• wayfinder, paginator, or breadcrumb?

  - by LOTUSMS

  My question is fairly simple. I've heard one or two people call it a "wayfinder" and I personally call it "breadcrumb", then again "paginator" can also fit the bill. Bottom line is I can't seem to find what I need because I am not coming up with the right term. What I want is the following: I have a site with a multiple-pages form. I want my users to see the steps through the form. I searched for all three terms and nothing I can use has shown. I could build one from scratch but I am interested in what is out there. Someone may have done a better job than I will be doing. Any idea on what to call this and if you have a link I can check out, that will be bonus Thanks

• 12.04 install now just blank screen

  - by bull

  I have attempted to install a new copy of 12.04 using usb stick instead of using download manager. Everything went fine while using usb stick until I restarted after installation was complete. Then, I got the screen with cursor and 4 lines of script with the first line saying "could not write to bytes: broken pipes". I have used several versions of Ubuntu from 6.04, but this one seems broken. I have tried nouveau.blacklist and many other suggestions to no luck. I am using hp pavilion m7790y dual core processor system, with nvidia 7600gt video card, 4gb ram and two hard drives with Vista on one and fresh install of Ubuntu 12.04 on other. I'm still looking for help to solve this problem. Thanks in advance.

• How to deal with OOP design problems in interviews?

  - by haps10

  This is a question where I seek guidance from fellow/senior developers to get into my dream company - it's a pioneer in OOP and Agile. I've already failed once to clear an interview. One part I feel most challenging is to come up with a proper Object Oriented design(classes, interfaces, methods, interactions etc.) in a very short time for certain situations like Pacman, Game Of Life and so on. As the problems are unprecedented ones - my approach is mostly to try different things and then make decisions - which they feel is not clear and not what they expect from a developer with 5+ years of experience. I've already studied a few books on patterns, OOP - it didn't help me much and I think it'll take a bit more than that. Could some one please guide on what specifically shall I practice so that I can do better at design problems as above. I want to refine my approach and have a better thought process.

• How to set up dual wired and wireless connections?

  - by Col

  My laptop has both wireless and a wired connection capabilities. Can I connect to a router A using wireless and a separate router B using wired ethernet at the same time without having to switch back and forth? Thanks for replying so quickly. I wish to connect to two separate networks. The wireless connection is to router A which is connected to broadband internet. The wired connection is to router B which I wish to share files and a printer on 1 or 2 other desktops also using wired connections on B and maybe using synergy to have only one keyboard and mouse for 2 desktops. The wireless laptop is the only one required to have internet access.

• I finished "Beginning Android Games", should I use its framework?

  - by orod

  I've worked through Mario Zechner's "Beginning Android Games" and have made my own pong and asteroids game using the framework used in the book. I have also downloaded the source code for Replica Island and am able to run that. I like Replica Island's framework over the one I made from reading the book. Some differences are that Replica Island uses different activities for each screen instead of Zechner's Screen class and that Replica Island can use a lot of textures and isn't limited to textures with dimensions of powers of 2. If I'm serious about writing games and apps for Android should I learn Replica Island's framework and use that instead of the one I made while reading Zechner's book?

• Delete all traces of windows from Ubuntu

  - by TheOm3ga

  I used to have a dual boot in one of my hard disk drives - Ubuntu and Windows 7. Then, I added a SSD which is now my main hard disk drive, and I'm using it for Windows 7 completely, keeping Ubuntu in the old HD. I restored the Grub so everything works ok, except for one thing. Everytime I update the grub, it detects two windows: Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 Obviously, I don't want it to detect the Windows on sdb1. Because I no longer use it (I manually deleted the files). What can I do about that without wiping out completely the partition?
