• Best keyboard drawer for programmers?

  - by David Pfeffer

  I'm a programmer with pretty severe neck problems. I program with three monitors, and I've found that my desk's short depth causes me to have to rotate my neck too much to see the "wing" screens. I can't get a deeper desk due to space restrictions. I'm looking for a keyboard drawer that can be installed onto a desk. However, I like the height of the keyboard on the desk. I'd like a drawer that is extremely low-profile/slim. My keyboard is less than 1" tall, so it'll fit pretty much anywhere. My ideal product would slide out from under my desk and "pop up" so that its surface is even with the desk. Does anything slim and nice like this exist? I'll even consider replacing the desk if a desk exists with this built-in.

• Can someone explain to me C#'s coding convention?

  - by AedonEtLIRA

  I recently started working with Unity3D and primarily scripting with C#. As, I normally program in Java, the differences aren't too great but I still referred to a crash course just to make sure I am on the right track. However, My biggest curiosity with C# is that is capitalises the first letter its method names (eg. java: getPrime() C#: GetPrime() aka: Pascal Case?). Is there a good reason for this? I understand from the crash course page that I read that apparently it's convention for .Net and I have no way of ever changing it, but I am curious to hear why it was done like this as opposed to the normal (relative?) camel case that, say, Java uses. Note: I understand that languages have their own coding conventions (python methods are all lower case which also applies in this question) but I've never really understood why it isn't formalised into a standard.

• How to make the working environment of a programmer less shiny?

  - by Roflcoptr

  Last year I had a sport accident and since then my left eye is a little bit sensitive. Especially if looking in bright and shiny colors, I get tired very fast and can't literally focus on anything. White is the worst color ever! Unfortunately most application that I use in my work environment (Firefox, Eclipse, Visual Studio, Tetris) have a very bright white background. This really hurts my eye. So is there an easy way to generally use color schemes on the laptop so that everything isn't that bright? Obviously I could everywhere change the default color scheme, but isn't there a simpler solution to do that? Or any recommendations what are good color schemes to be less bright but still clearly readable?

• Running 32-bit Firefox with sun-jre in 64-bit Ubuntu

  - by rojanu

  I am trying to run juniper networks connect program to vpn into work and it only works on 32bit sun jre. All the things I have found with google failed so far. I can't use any scripts, like madscientists, as part of the authentication I need to provide some random characters from a grid. So to isolate this 32bit app install to a corner, I downloaded firefox and jre and unpack them to /opt. I run firefox with sudo as Juniper asks for root password. Here is Firefox plugins folder /ot/firefox32/plugins# ls -la total 8 drwxr-xr-x 2 root root 4096 Mar 11 00:57 . drwxr-xr-x 11 root root 4096 Mar 10 23:48 .. lrwxrwxrwx 1 root root 49 Mar 11 00:57 libnpjp2.so -> /opt/java/32/jdk1.6.0_31/jre/lib/i386/libnpjp2.so Firefox lists sun jre but when check it with "http://java.com/en/download/installed.jsp" it either can't detect java or Firefox freezes Any Ideas? Thanks

• How do I install Nautilus-Elementary?

  - by Srinivas G

  I've added the am-monkeyd PPA and upgraded my system. Yet, there's no sign of elementary in my fresh Maverick RC install. Have I done anything wrong? The PPA upgrades the default nautilus package and there is no separate "nautilus-elementary" package as of now. Now, there are three versions listed in the package properties: 1:2.32.0-0ubuntu1-ppa1 (maverick); 1:2.32.0-0ubuntu5~ppa5 (maverick); 1:2.32.0-0ubuntu1 (maverick); Anything you can make out from this?

• How do i make/setup a mailing list?

  - by acidzombie24

  I know i could program it myself but maybe there is a simple (thats the keyword) package. I like to add a box, snippet, form or page to my site for users to input their email address. Then i'd like it to automatically send email saying you have successfully subscribe. I'd want an unsubscribe link and i would be using smtp on google apps. I would like to send email with html so i can have a simple sentence with a complex link such as this I dont know if i'll get marked as spam if i try to send everyone an email at once? so i'd like the software to manage it. Also i'd like to get the emails in a simple format like csv. Is there a simple app that does this? if not i can write a simple form which does a simple insert (or delete when unsubscribing) and write a 200-300line app to send my emails out for me.

• English as a system language but Russian regional settings

  - by mbaitoff

  I usually choose English as an installation language since I believe that the original is better than the translation. However, the environment I'm working in is mostly Russian, so I have to deal with locale specificity. Even worse is the fact that selecting English yields to royal measurement system, that is, feet, inches, and damned letter paper size. Whatever I do, I didn't manage to get rid of letter paper size - eventually here and there I stumble upon letter as a hidden default, and that spoils my prints. How can I select and use English as my language, but use metric system everywhere and a4 paper size everywhere, and Russian regional settings (date, time, decimal etc).

• Rich text format area size in SDL Tridion 2011 SP1

  - by Alvin Reyes

  I've set a schema field to height 2 and see the following for the input area in Chrome and IE. I'm expecting to have text area that's 2 lines high based on the default text size. I removed the source view option, thinking the tab might affect the size, but it still appears to be about 5 lines in height instead of 2. It seems to match 2 lines if the text is set to a large font or to a heading. I'd like to minimize the size these fields take in the content entry form as well as hint that authors should enter a smaller amount of text. How do I make this match the expected 2 lines?

• *Code owner* system: is it an efficient way?

  - by sergzach

  There is a new developer in our team. An agile methodology is in use at our company. But the developer has another experience: he considers that particular parts of the code must be assigned to particular developers. So if one developer had created a program procedure or module it would be considered normal that all changes of the procedure/module would be made by him only. On the plus side, supposedly with the proposed approach we save common development time, because each developer knows his part of the code well and makes fixes fast. The downside is that developers don't know the system entirely. Do you think the approach will work well for a medium size system (development of a social network site)?

• How do I clear xmodmap settings?

  - by Wayne Werner

  Exactly what the title asks. How do I clear xmodmap settings? I have an IBM model M, and somehow xkeycaps got it into its head that my "End" key was not any key at all. xev reports keypresses when I use it, so I know the event is being generated by the keyboard. Also, xkeycaps thinks that my arrow keys are all wonky, and apparently the scrollbar is broken so it only scrolls down - so I can't scroll up to find an IBM keyboard that just maybe is close to my map so I can fix my keys. So I'm trying to reset my keyboard to the default settings, but the xmodmap manpage is woefully devoid of "reset all" or "clear all" or anything of that nature (that I was able to find). Help would be greatly appreciated!

• Why the Enter key in a Mac keyboard is mapped to Level?

  - by Anentropic

  Just installing Ubuntu for the first time, glad to ditch Win 7. I have a KVM switch and also a Mac, hence I'm using a Mac keyboard (the full size alu one) Everything's pretty cool. First thing I wondered is why the numeric keypad doesn't work? Oh, I have to find the num lock key (which should default to on, sensibly, no?) which isn't labelled as such on a Mac keyboard. Ok no problem. Then for some reason the Enter key on the keypad doesn't work still. Check the keyboard layout (set to 'English UK Macintosh')... inspecting the layout the Enter key is mapped to something called 'Level' - WTF is 'Level'? Everything else about the keyboard works great ie the £ $ # @ " are all perfect, volume control works as expected... why this weird key mapping on the Enter key? More importantly... how do I change it to work as an Enter key ?

• Why are most GNU's software written in C

  - by BallroomProgrammer

  I am a Java developer, and I rarely write GUI program in C. However, I noticed that many GNU's projects, such as PSPP, R, Dia, etc., are written in C, instead of Java or C++. I personally don't mind this, but I am really curious why GNU favors C so much. My understanding is that C is the one that supports the least in object-oriented programming, and today's CS education really emphasizes OOP, as OOP really makes codes more reusable. In this case, why would so many developers choose to develop in C instead of C++ or Java. Does anyone know why GNU's software are so exclusively written in C? Do you think or GNU's software should be written in C++ or Java so that the source code could be more useful to people? Why or why not?

• How To Access the Developer Options Menu and Enable USB Debugging on Android 4.2

  - by Chris Hoffman

  In Android 4.2, the Developer Options menu and USB Debugging option have been hidden. If you need to enable USB Debugging, you can access the Developer Options menu with a quick trick. The developer options aren’t just used by developers. USB Debugging is required by adb, which is used for rooting an Android device, backing it up, installing a custom ROM, taking screenshots from a computer, or doing many other things.

• How to dynamically insert a keyword in an Amazon Search Widget

  - by ElHaix

  Through Amazon Associates, you can create search widgets that have a place for a search term. In the admin, you can set the default search term, but that seems to be tied to the widget ID. I would like to be able to dynamically set the search term for the widget when it is displayed. How can I accomplish this? Note: I am referring to the following banner script: <SCRIPT charset="utf-8" type="text/javascript" src="http://ws-na.amazon-adsystem.com/widgets/q?rt=tf_sw&ServiceVersion=20070822&MarketPlace=CA&ID=V20070822%2FCA%2F[PARTNER-ID]%2F8002%2F84cb1754-d9ab-48de-b96b-574927fa9599"> </SCRIPT> <NOSCRIPT><A HREF="http://ws-na.amazon-adsystem.com/widgets/q?rt=tf_sw&ServiceVersion=20070822&MarketPlace=CA&ID=V20070822%2FCA%2F[PARTNER-ID]%2F8002%2F84cb1754-d9ab-48de-b96b-574927fa9599&Operation=NoScript">Amazon.ca Widgets</A></NOSCRIPT>

• Anti-aliasing changed after update (or something...)

  - by Mussnoon

  The anti-aliasing of my system (of GTK?) has gone weird after I did one of two things - do a system update, and install gimp 2.7 beta. See images: Before: After: Before: After: Here's the current rendering comparison between Chromium, Firefox and Opera (in that order): Does anyone know how I can get the old anti-aliasing back? As far as I can tell, I never did anything special to achieve that before. It has always been on the default settings since I installed Lucid few months ago. Update: I have tried different settings (even though I knew they were already at the "best" settings) in appearance fonts ( details) but, as expected, any change there only makes things worse.

• Server Side Developer Prerequisites

  - by Jking

  I am new to server side development and am currently learning node.js. What sort of networking information should I be familiar with to allow for a smooth learning curve with server side development. Could anyone provide resources pertaining to the information required to get into server programming? To give you a better idea of my standpoint: I do not know how a server interacts with a database [Q: How does a NoSQL database, or database in general, communicate with a server?] I am unsure of how a web stack works [Q: I have heard of LAMP but do not know how Apache, MySQL, and PHP interact. Hopefully this applies to other stacks as well. How do the components of a stack work together? Also, is a MEAN stack an alternative, or is it completely irrelevant to this] I have trivial knowledge of internet protocol [however extremely inefficient][Q: What resources are beneficial when learning about networking, and how much/what knowledge should I acquire to program on the server side] I am unsure of what I am unsure of concerning networking information necessary to start development Information on how the client-server model works would be greatly appreciated

• Java 7 Adoption at 79%

  - by Henrik Stahl

  According to a recent blog post from the cloud hosting company Jelastic, Java 7 adoption on their platform is now at 79%. While this is a single data point and should not be read too broadly, it does match other indicators we have that Java 7 is picking up, such as uptake among Oracle middleware customers, download statistics and online activity. The spike in adoption in April coincided with the release of JDK 7 Update 4. This is in line with our expectations since that release added Mac OS X support as well as java.com moving to Java 7 as the default download for end-users; two events that marked the maturity of Java 7 to the community. Since the original release of Java 7, Oracle has shipped 7 update releases, added ports to Mac OSX and Linux/ARM and expanded JavaFX to all common desktop platforms.

• Ubuntu 12.04 GTK Problem

  - by Dana Holt

  I am running Ubuntu 12.04 and compiled and installed GTK 3.4 to go through some GTK developer tutorials. Installing this version of GTK has caused problems with Unity. All system dialogs and top bar now have a different (older) look, and when I try to launch Nautilus I get the following message: Gtk-Message: Failed to load module "canberra-gtk-module" Initializing nautilus-open-terminal extension Initializing nautilus-dropbox 1.4.0 Initializing nautilus-gdu extension nautilus: symbol lookup error: nautilus: undefined symbol: ubuntu_menu_proxy_get I have run make uninstall on the newer version of GTK and reinstalled just about every package I can think of, but I am still having the same problem. How can I repair the default Ubuntu GTK libraries? EDIT Also, I noticed that my desktop icons are gone (launcher works), and I can't interact with the desktop. I can't drag any shortcuts to it, etc.

• Multiple problems while installing Ubuntu 13.04 on LENOVO G500 laptop

  - by Balazs Kiss

  Dear Community, I encountered several problems when installing Ubuntu on my new Lenovo G500 laptop. First I bumped in the problem (also reported by many other) of the black screen after booting Ubuntu. This problem I recould solve by changing the "quiet splash" record of GRUB to "nomodeset". Ubuntu install was successful then. After the installation, I had a black screen again when booting up for the first time. I booted up again with "nomodeset", and enabled the external AMD driver at Hardware Drivers. Booting still do not worked (only with nomodeset), and when I log in, the system gives me a "System program problem detected" message, and the system (desktop) does not load in. Please, can you advise me what to do? Shall I re-install Ubuntu? What are the steps to make my ubuntu work with this harver? Hardware: LENOVO G500 with IntelCore i5-3230M 3,2Ghz processor and AMD Radeon HD8570 integrated chip Thank you for your help in advance!

• Electronic circuit simulator four-way flood-filling issues

  - by AJ Weeks

  I've made an electronic circuit board simulator which has simply 3 types of tiles: wires, power sources, and inverters. Wires connect to anything they touch, other than the sides of inverters; inverters have one input side and one output side; and finally power tiles connect in a similar manner as wires. In the case of an infinite loop, caused by the output of the inverter feeding into its input, I want inverters to oscillate (quickly turn on/off). I've attempted to implement a FloodFill algorithm to spread the power throughout the grid, but seem to have gotten something wrong, as only the tiles above the power source get powered (as seen below) I've attempted to debug the program, but have had no luck thus far. My code concerning the updating of power can be seen here.
