• test coverage reality

  - by iPhoneDeveloper

  I am NOT doing test driven development and I write my test classes after the actual code is written. In my current project I have a test coverage of(Line coverage) %70 for 3000 lines of Java code.(Using JUnit, Mockito and Sonar for testing) But while I feel actually I am not covering and catching %70 of the problems that can occur. So my question is in theory is that possible to have a %100 Line coverage but in reality it is meaningless because of low quality of the test code and maybe a %40 well written test code is much better than a bad %100 coverage? or we can always say line coverage more or less gives the percentage of all covered issues?

• Faut-il en finir avec la mode NoSQL ? Ou est-ce plus qu'une simple mode passagère ?

  Faut-il en finir avec la mode NoSQL ? Ou est-ce plus qu'une simple mode passagère ? La question est volontairement provocante. Elle est posée, en des termes encore plus crus, par Ted Dziuba dans un billet intitulé « I Can't Wait for NoSQL to Die ». « Certains ingénieurs pensent que l'évolutivité et l'architecture sont la solution [de tous les problèmes]. C'est comme cela qu'est né le mouvement NoSQL », y écrit-il. « L'idée développée avec NoSQL est que toutes les bases de données relationnelles, telles que MySQL et PostgreSQL, sont caduques et que les bases de données fondées sur des documents ou les bases de données sans schéma représentent l'avenir». ...

• Brightness problem NC110 (Samsung)

  - by user40532

  Translated into English Hello everyone. It looks like I'm not the first person to have this problem, but since I'm new in the Ubuntu community, I don't know how to launch the terminal. There you have it; I have a NC110 (Samsung) and I'm not able to tweak the screen's brightness. What are the steps to follow? Original question in French: Bonjour à tous.

Voilà, j'ai un NC110 (samsung) et je n'arrive pas à modifier la puissance de l'éclairage de l'écran. Quelle est la marche à suivre?

• If a variable has getter and setter, should it be public?

  - by Oni

  I am an about to graduate Computer Science student so probably this is a stupid question. If I have a class with a variable that is private and the class have getter and setter for that variable. Why don't make that variable public? The only case I think you have to use getters and setters is if you need to do some operation besides the set or the get. Example: void my_class::set_variable(int x){ /* Some operation like updating a log */ this->variable = x; } Thanks in advance!

• Gtk theme change doesn't apply to kde apps?

  - by Stefan Monov

  I changed the systemwide ambiance theme a bit (specifically the scrollbar css), and this works fine in gtk apps, but in kde apps nothing has changed. They still have the vanilla ambiance look. I tried rebooting too. Btw I've disabled overlay scrollbars. I looked at this question: Why don't Qt4 apps in Lubuntu pick up the GTK theme? and tried setting the Gtk+ theme in qtconfig but that didn't help. The look remains the same. Changing the theme in qtconfig to another one, such as QtCurve, does have an effect though.

• Separating portion of website to its own server

  - by Brett

  So my job is to take the homepage (or maybe I should say "homesite" because it encompasses a few interrelated pages) and drag this onto its own Apache server. The problem I'm having right now is being able to weed out jumbled/bundled files (such as folders of js, css, and other files that i cant even identify) and knowing what is necessary to keep the homesite running. I'm new to this stuff (I'm an intern) so feel free to ask questions if I'm leaving vital information out. What I'm asking of you guys here is basically any pointers or tips you may be able to give me in order to get the job done. I could use some advice from people with a little more experience in web development. btw: This question may appear as though I have not completed any prior research and that is, for the most part, true. But the problem is I really am not sure how to research this. If you guys could throw me some keywords to play with that would really be helpful. Thanks!

• How can I customize an icon on the dash/launcher?

  - by user26272

  all. I have a question that has been bugging me recently.. Say I install Blender.. I am using the Bumblebee project thing, so in order to properly use it, I have to go to the terminal and type "optirun blender". If I just click on the icon on the dash, it will run without the proper parameter being passed. Is there a way I could customize the Blender launcher on the dash so it would always launch it with the optirun parameter? Thanks.

• Creating a Application in Winrt that requires Internet

  - by wtsang02

  I am making a paid App for Windows 8, c#. I am wondering which is better? If my application doesn't need internet connection normally but does requires internet connection for the first time to download content data. --Makes my life easier Load the default data when installing. Then ask the user if he wants to update in app. -- Making the default data will be pain. Now my big question is, is it safe to assume user has access to internet now-a-days when using application that shouldn't require internet?

• How to open the terminal? (Mis-configured the profile)

  - by JiminP

  I am quite new to Ubuntu. (I started to use Ubuntu about a year ago, but I don't know how to use things like terminal well. All I used by console was easy things like ls or cd, to use gcc.) Today, I found 'profile' property of the terminal, and I created a new profile. Then, I changed some properties like font color and opacity. Soon, I found something like 'command', and for test, I set that to ls. I closed and re-opened the terminal. However, the terminal terminates right after it appeared. I soon remembered that there was option like 'close right after the command is executed'. Therefore, I can't use Gnome Terminal D: ... I found Konsole at Ubuntu software center, but that's just not my style (especially cursor, its position is little weird...). Question : How to change the profile of Gnome Terminal, without opening it?

• Disable automatic starting of sshd?

  - by b.long

  Simple question here; what's the correct way to stop the sshd service from starting when the OS boots ? I'm not sure if this answer is correct, so I'm hoping some guru(s) can help me out! What I'd like is a configuration that (after boot) allows me to start the service using sudo service ssh start when necessary. Version info: me@home:~$ ssh -V OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 me@home:~$ lsb_release -a No LSB modules are available.

• Survey says: Java technology rules

  - by hinkmond

  Eclipse came out with their Open Source Developer Report and Survey for 2012. In it, we see (in the words of the immortal Richard Dawson, RIP) "Surveys Says!": Java computer programming language is on top. See: Java is the top Here's a quote: The Eclipse community was invited to participate in the survey between April 23 and May 15 of this year. Skerrett says the Foundation promoted the survey primarily through social media (Facebook, Twitter) and online forums. Of the 840 people who responded, 732 completed the survey... So, now we know who's on top, we can keep this in mind the next time this question comes up on Family Feud. Hinkmond

• Upstart: sense of "stop on..." stanza when job is a task

  - by Binarus

  Hi, an upstart question (I think I have read all relevant man pages but could not find the answer there): What is the sense of using a "stop on ..." stanza in the definition of a job which is a task? The manuals tell us that such a job, after being started, just waits until its script (or exec stanza) is executed completely, and then stops automatically. Given that, what is the point in using "stop on ..." stanzas in such job definitions? For example, this is the job definition for Upstart's (very important) rc job in Natty 11.04 (leaving out comments and empty lines): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL IMHO, the job, after being started by a runlevel event, will be stopped automatically as soon as /etc/init.d/rc $RUNLEVEL has finished. Thank you very much for any explanation!

• Creating Ubuntu bootable disk on my phone

  - by Aerus

  I want to install Ubuntu 12.04 on my laptop but because I have a complete shortage of writable CDs and DVDs, I wan't to create a bootable USB stick (on Windows). However, the only USB stick I currently have lying around is my HTC phone (HTC Touch HD with 8Gb memory). I was following the Ubuntu guide to create a bootable usb stick with pendrivelinux, however in the last step it shows me that it wants to do more than just copying the .iso file to the USB drive: My question: can I safely proceed without wiping the current OS off my phone (Windows Mobile 6.1) and use it to install Ubuntu?

• Canon Pixma MP150 printer stops before the job is done

  - by aserwin

  I have a Canon Pixma MP150. It's old but it still works well. The problem is that since I have been running Ubuntu 12.04 the printer exhibits odd behavior. Usually right at the end of a job, it will stop. The printing is done, but the printer is still "working" and it won't release the paper. If I pull it out and test the printer, it will start over and print the same job. Once I just let it be and about an hour or so later it finished with no problems. My question is, could the be an issue with the printer (it is old) or is it the drivers in Ubuntu? Any advice (or suggestions on debugging) would be greatly appreciated as I print a lot and don't really want to buy a new printer.

• Programmer's career path

  - by kender

  I've been working as a programmer for the last few years - different companies and freelancing, mostly developing internal-business web applications (well, that's the current model of development, it seems). Besides simple coding I was working on specs, designing applications, and all those around-like things. My question is, what's the career path I should be aiming for? Is it like working on code for the rest of my life? :) Or do programmers make a good manager-position people (I know, those require quite different set of skills) and I should try to improve myself to this direction? I know it's very subjective. Thing is, lately I find myself much more into the designing/working on specs part of the development project then the coding itself. How do you see it? Would you like to go from development to management? Would you like to work on a project with a manager that used to be a coder? Would you like to hire one? :)

• To canvas, or not to canvas, when building browser-based games?

  - by Letharion

  Background: I have extensive development background, but the last time I coded a game was many years ago. My Javascript skills are quite limited, and I intend to improve them by building a simple game — Tetris, Pac-man, or something of that complexity level. Question: It seems to me that a fundamental choice I need to make is whether I should render on a <canvas> element or not. With a canvas, I have basic tools for rendering points, lines, and more complex things on top of that. Presumably there are, or will be, also various frameworks to help with this. Without a canvas, I could keep my objects in the DOM-tree, like a regular webpage, only quite complex, with many overlapping elements. Is one approach better than the other? Are they mutually exclusive? How do I know which to pick?

• Elantech trackpad being identified as a logitech wheel mouse

  - by user11895

  I recently purchased a Samsung RF510 laptop computer, which I absolutely love. However, upon installing Ubuntu 10.10 onto it I couldn't get the trackpad to function properly. It worked as a basic mouse (point and click) but had no functionality for edge scrolling or any of the multitouch settings the trackpad is capable of. After doing a lot of research I discovered the reason is a known issue where the Ubuntu kernel will improperly detect an Elantech trackpad as a logitech PS/2 wheel mouse, and as such will gain none of the functionality that seems to be coded for synaptics trackpads. The question I have is: does anyone know a way to get this working properly? This is my first time trying to run Ubuntu on a laptop (actually, it's my first laptop in the last 12 years) and I'm finding the experience to be intolerable without the basic scrolling/zooming/etc I've been used to using for as long as I can remember.

• Have you tried to switch to different kind of language and find a job in a "new language" ?

  - by IAdapter

  I'm a Java programmer(J2EE/JEE), but I'm thinking about switching to C#. Does any of you have been in my position and have switched from Java to C# or C# to Java or C++ to Java, etc. ?? I'm NOT asking about switching between the same kind of languages, for example Java to Groovy/Scala/JRuby, C++ to C, VB to C#, C# to IronRuby/F#/VB.NET. Or if you company was C++, but has moved to Java(you had no choice and I'm about to make a choice). Side question: How hard was it to get a job in a "new language"?

• What significant advances lost on side tracks should be revived in the main stream of software?

  - by C.W.Holeman II

  In reading Alan Kay's question on Significant new inventions I was coming up with answers that were not new ideas but old ones that have been passed by in the main stream. So, what significant lost advances that happened on a side track should be revived in the main stream of software? These would be ideas that worked well in their context but a different context appeared and became dominant the context, even though it lacked the idea. It maybe that in the new dominant context one just cannot do something or it requires great effort to be exerted.

• How do I optimize SEO in a multiblog WordPress install?

  - by user35585

  We are about to launch two product pages plus a corporate website. The goal is to keep a blog in all of the sites, but here it comes the question about how to do it in a way we get everything unified but do not mess with Google's web crawlers. We considered the following options: Putting a blog from which we retrieve two categories with custom CSS, so we have a blog that sub splits two category-dependent blogs; this way we can get the feeds and will point to it Putting two product blogs of which we retrieve their posts into a bigger, corporate blog Putting three independent blogs Despite I was for the first option, so we only have to address our content from the product pages, I would sincerely like to hear your opinion. We are afraid duplicate content or strange link games may make us lose PageRank. How would you do it?

• How can I undo this key mapping?

  - by user273872

  First of all sorry my punctuation will be bad. its hard to type when keys are not doing what you expect. Eg it keeps scaring the **** out of me by taking a screen shot when I push the up arrow lolol So anyways, I broke a key on my keyboard and used xkeycaps to remap it to an unused key which worked. But then I realized it screwed up other keys... I think this is the program I used http://www.jwz.org/xkeycaps/man.html And then after doing the modifications I found out how to save them from the second answer in this question How to Map my enter key to a different key down where it says this "When you are happy with your current keymap and want to use it in future X-sessions, run the following command to save it: xmodmap -pke ~/.Xmodmap"

• Hosting a magnet link site which could possibly infringe copyrighted material?

  - by Griff

  I have for the last 3 months built a crawler, indexer and alot of other things for what started out to be a home project for indexing magnet links on the internet. As my project grew I have thought about releasing my collected data (which at the minute is on a public domain but with no access) to the public. Whatever the crawler sucks in goes in, and whatever the indexer decides to index gets indexed as it is a fully automated process. My question is as follows; Considering that most of the data that is collected from what I have built points to illegal copyrighted material (as most magnet links do) where would it be best to host such a site. I notice all of the already public torrent sites are hosted in India is this because there laws are less strict on copyright infringement? Have any of you hosted such a site, and if so what problems have you ran into? And as always any advice on being a webmaster for this type website?

• Ubuntu on galaxy note II

  I recently bought Samsung Galaxy Note II on android 4.1. It was my idea to try to turn it into a pc and I bought a micro-keyboard for the same purpose. I had hoped there would be an app for OpenOffice, but there isn't. Now i see that ubuntu may be installed on smart phones. I already have ubuntu - including OpenOffice - on my laptop. My question is: is it possible to install ubuntu to galaxy note II, and if so, does it include office programs and other ubuntu programs? Thank You And thank you so much for an alternative to Microsoft.
