  • Test descriptions/name, say what the test is? or what it means when it fails?

    - by xenoterracide
    The API docs for Test::More::ok is ok($got eq $expected, $test_name); right now in one of my apps I have $test_name print what the test is testing. So for example in one of my tests I have set this to 'filename exists'. What I realized after I got a bug report recently, and realized that the only time I ever see this message is when the test is failing, if the test is failing that means the file doesn't exist. In your opinion, do you think these $test_name's should say what the test means if successful? what it means if it failed? or do you think it should say something else? please explain why?

  • First programming language: PHP, Ruby, Python?

    - by Victor
    I've been a Web developer for over 5 years and am looking to start building more complex Web apps. Currently, I know HTML/CSS/Javascript but I feel it's time to start learning something else. I work with a lot of applications based on PHP. I created a vBulletin forum on my own time and I would definitely want to build off of that since it has gained a bit of popularity. I also work with Wordpress quite often. All of the software I work with tends to be based on PHP but I hear a lot of people say Ruby or Python is better. Since I'm starting out, I really don't care which one I learn but I want to start right. Any recommendations for someone with HTML/CSS/Javascript knowledge but wants to branch out?

  • Ubuntu 12.04 not Locking Encrypted Hard Drive on Log Out

    - by J.L.
    I'm running Ubuntu 12.04 with Gnome 3.4. I have two external hard drives. I encrypted both using Ubuntu's Disk Utility. When I use Nautilus to mount them, I'm asked for my decryption password. Regardless of whether I then click "Forget password immediately" or "Remember password until you logout", though, I find that Ubuntu does not lock the drives when I log out. Rather, when I log back in, they're still mounted. (To be clear, restarting the computer does unmount them so that they require the password on the next log in.) I'm concerned that these drives are remaining unprotected when I log out without restarting my computer. I would be grateful for help understanding whether this is a bug. Thank you!

  • Unity launcher autohide leaves "ghost" behind?

    - by Hailwood
    In 12.04 I had the launcher set to autohide, which worked perfectly. However in 12.10 I am getting a strange "ghost" issue. Take this screenshot, with me having a maximised google chrome window, mousing over the back button. As well as this, I also get another ghosting issue when I have the panel set with an opacity, whereby whatever is in approximately the middle left of the screen gets mirrored up to to panel, but only when I move/switch to a window. But that one is not so annoying as the autohide bug, how can I fix that?

  • How to get started with embedded systems in the airline or submarine industries?

    - by Jason
    Hi, Not 100% sure how to frame this question but here goes... I currently work as a Rails developer but want to work on more substancial / "meaty" projects and have always been very interested in embedded systems, especially systems that run on aircraft and especially submarines.....I know strange combination. I have been doing some searching & found lockheed martin produces a lot of underwater systems for various navys around the world e.g. http://www.naval-technology.com/projects/nssn/ However, there is very little information about what software is used within these systems, what OS's they use or anything else "technical", presume there is a lot of C / C++ involved but that is just a guess... so its hard to know where to even begin learning what is required to potential work in these areas. Just wondering if anyone has any experiance working with or more information about embeddeed systems in either the airline (onboard flight systems) or especially submarine systems? Thanks!

  • How to Promote iPhone App

    - by Ricibald
    I published my app. I request a review to more than 150 sites but only 8 of them give me a (good) review. I can't reach the most famous blogs because I have to pay to bring on top of their queue. Now, my app seems to be nice but I have only 65 users playing it. This 65 users seems to really like it because I can see there are a lot of games played tracked in my stats. A lot of users say that my app is "fun like Doodle Jump and very addictive". So, what's the problem? Why only 65 people? In a word, how can simple games such "Doodle Jump" or "Flight Control" enter in top 10? What's their secret? What's my mistake? UPDATE: I have a site describing my app.

  • performance of parameterized queries for different db's

    - by tuinstoel
    A lot of people know that it is important to use parameterized queries to prevent sql injection attacks. Parameterized queries are also much faster in sqlite and oracle when doing online transaction processing because the query optimizer doesn't have to reparse every parameterized sql statement before executing. I've seen sqlite becoming 3 times faster when you use parameterized queries, oracle can become 10 times faster when you use parameterized queries in some extreme cases with a lot of concurrency. How about other db's like mysql, ms sql, db2 and postgresql? Is there an equal difference in performance between parameterized queries and literal queries?

  • SQL Server 2008 log size management problems

  • How can I stop LibreOffice from randomly crashing?

    - by Sam Mercier
    Libreoffice keeps on crashing randomly. It will do this when I am typing and when I am switching desktops or anything. There is no patter to it. I need some help here. Anyone had this problem or problem similar to it? Anyone have found a fix. Also it seems to happen especially prominently after my screensaver has started. I would say it happens about 97% of the time after that. This is an annoying bug and is keeping my productivity low.

  • Lubuntu 12.04 is a non-LTS release - does this mean that LXDE isn't, either?

    - by MHC
    Lubuntu 12.04 is not a long-term-support release. That's mostly due to a lack of manpower. But I don't use Lubuntu on my machine, I use LXDE over stock Ubuntu 12.04 LTS. So my question is: In the next five years, will there be security updates and bug fixes for LXDE-packages such as Openbox, PCmanFM and LXsession? Or does the "LTS" in 12.04 LTS only include stock Unity packages? I guess this question is just as relevant for any other DE out there.

  • "sudo apt -get install foo-" causes removing foo package and everything depends on it

    - by M.Elmi
    While working in command prompt, I accidentally typed following command: sudo apt-get install python3- and ubuntu started removing python3 and everything depends on it (including firefox and much more). Fortunately I closed that terminal immediately and reverted everything by checking dpkg log file, but I was wondering why an install command should act like remove? Is it a bug? Consider the situation that you are looking for a package name (pressing Tab twice) and going through possibilities by pressing Enter key and those Enter keys remain in the keyboard buffer and.... youhaaaa... apt-get is removing the entire installation in front of your eyes.

  • jpegexiforient does not seem to work in 12.04

    - by Pointy
    In Ubuntu 12.04, the jpegexiforient command doesn't seem to work. I've got a .jpg file for which exif clearly shows (correct) EXIF orientation information, but running jpegexiforient on the file returns nothing. I don't particularly care about that command, but it makes exifautotran not work. I could (and might) rewrite that script to use exif instead, but I'm just wondering if there's something dumb I'm just doing wrong. I found this somewhat old bug report but its suggestion of running exif to update the setting didn't make any difference. Does jpegexiforient work for anybody?

  • KDE's Dolphin Can't See Connected devices such as Nikon, Canon Cameras

    - by Swapnil
    I have noticed this problem across all distros including Kubuntu and openSUSE. Many times my Nikon D 7000 and Canon HF 11 are not seen or mounted by Dolphin. When I connect the Cameras I don't get any notification in the tray which otherwise shows connected device. Ironically when I open Nautilus then I can clearly see the cameras mounted. I also have a request that what these devices don't appear on Dolphin's side panel automatically. It makes life easier for a users. https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/956806/+attachment/2879913/+files/dolphin.png

  • How to get an internship with a low GPA?

    - by Jason Baker
    A lot of changed majors and some other mitigating circumstances have left me with a pretty low GPA. My GPA in the last couple of semesters hasn't been stellar, but my grades have gotten a LOT better. I want to try and start putting in some resumes to get a good internship this summer. I do think that I have some decent experience for someone at my level, but I see my GPA being a pretty big potential stumbling block. Is there anything I can do to help my chances of getting a good internship? (For the record, the mitigating circumstances aren't something I'd feel comfortable discussing with a potential employer. I'd prefer getting a job by proving my merit, not making excuses.)

  • Bitbucket and a small development house

    - by Marlon
    I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of shared folders! In the process of rolling this out, I am thinking of different strategies to manage our stuff and I am leaning towards using Bitbucket as our "central" repository. The projects in Bitbucket will solely be private projects and everyone will push and pull from there. I am open to different suggestions, but has anyone got a similar setup? If so, what caveats have you encountered?

  • How can I edit/create new launcher items in Unity?

    - by Ike
    Will Unity allow making custom launcher icons from .desktop files or via menu editing system? (Right now the launcher doesn't give the option to "keep in launcher" on all programs. For some programs I use, I have to make custom launchers or .desktop files. For instance, daily blender builds are generally just folders with an executable. In basic gnome or kde, I can make a new menu entry with the menu editing system. Then, I can also add it to docky either from the menu or by dragging a .desktop file to it. Unity launcher doesn't support drag and drop, so thats not a bug or anything, but when i open a .desktop file, it has unpredictable results. Most time it will not have"keep in launcher". Sometime it will have a pinnable item without the .desktop's icon, and if i pin the item to the launcher, it will not call upon the program again after closing it. I've also gotten it to just work with a .desktop file for "celtx".

  • asp.net Background Threads Exception Handling

    - by Chris
    In my 3.5 .net web application I have a background thread that does a lot of work (the application is similar to mint.com in that it does a lot of account aggregation on background threads). I do extensive exception handling within the thread performing the aggregation but there's always the chance an unhandled exception will be thrown and my entire application will die. I've read some articles about this topic but they all seem fairly outdated and none of them implement a standard approach. Is there a standard approach to this nowadays? Is there any nicer way to handle this in ASP.NET 4.0?

  • migrating product and team from startup race to quality development

    - by thevikas
    This is year 3 and product is selling good enough. Now we need to enforce good software development practices. The goal is to monitor incoming bug reports and reduce them, allow never ending features and get ready for scaling 10x. The phrases "test-driven-development" and "continuous-integration" are not even understood by the team cause they were all in the first 2 year product race. Tech team size is 5. The question is how to sell/convince team and management about TDD/unit testing/coding standards/documentation - with economics. train the team to do more than just feature coding and start writing test units along - which looks like more work, means needs more time! how to plan for creating units for all backlog production code

  • Display current layout (language code/country flag) in keyboard indicator

    - by Jono
    Just upgraded from 10.04 to 10.10, and the keyboard indicator applet no longer displays the two-letter country code for the active layout. This is terrible. Is this the default behaviour? Anyone using two layouts can't tell which language they're in. I can't seem to find the setting for this, it used to be in the preferences for keyboard layout. Update 1: In case this wasn't obvious - I have two keyboard layouts - English and Hebrew. I just upgraded form 10.04, where the country code (USA/IL) was displayed, overlaid on the flag. Now all I get is a vague keyboard icon, and can't find the settings for this. Update 2: this seems to be a bug that people have been reporting since Lucid, and is now back in Maverick

  • How do I get output into Java from a SELECT stored procedure in Oracle?

    - by Ventrue
    I'm using Java to connect to an Oracle 10 Database. I want to create a stored procedure (don't ask why) that takes no arguments and returns a lot of rows. Specifically, in Java I want to be able to get this data with something like: ResultSet rs = stmt.executeQuery("call getChildless"); where getChildless is the query: SELECT objectid FROM Object WHERE objectid NOT IN (SELECT parent FROM subparts); However, I just cannot for the life of me figure out how to get my output from the stored procedure. I've googled it and I get all this sample code that Oracle won't compile, presumably it's for a previous version. Refcursors seem to come up a lot, but I'm not sure if that's what I actually want, to use it with a ResultSet.

  • Doubts regarding the behaviour of 'autoremove' command and '--auto-remove' flag

    - by Jasper Loy
    After reading several man pages and forums, I thought that running 'apt-get autoremove' without any following argument removes all unused dependencies left on the system, while running 'apt-get autoremove xxx' removes xxx together with its unused dependencies. However I found this to be not true. Running 'apt-get autoremove xxx' not only removes xxx together with its unused dependencies, it also removes all other unused dependencies. So I tried to run 'apt-get remove --auto-remove xxx', thinking that this would remove only xxx and its unused dependencies. To my surprise, this also removed xxx, its unused dependencies and all other unused dependencies. Is this the intended behaviour of the commands or a bug? Is there any quick way to remove xxx and its unused dependencies without removing other unused dependencies?

  • Generating Dynamic web pages without server side scripting

    - by Microkernel
    Hi guys, I am trying to control a media device which has lot of multimedia content that it can play using another device(remote control device) like an ipad connected to the LAN. (UPnP) I want the media device to be able to send the content listing to the remote device so that it will be rendered as a webpage on the remote controller. And actions on the webpages needs to be sent to the the device as commands to execute (like play, pause, next etc). The media device is an embedded device, hence can't have any server side scripting, all has to be done on the client side. I want the page rendered to be HTML5. So, is it possible to generate dynamic HTML5 pages using just client side scripting? Thanks a lot. I am an embedded systems developer hence clueless about the web designing stuff.

  • redefine shortcuts for keys being set to default after reboot

    - by MYA
    i am using PHPStorm editor on Ubuntu 14.04. Everything is so smooth that I am loving the experience (especially the workspace experience is amazing) however this bug is giving me headache... some of the editor's short-cuts clash with default Ubuntu keys (Alt + Ctrl + Left,Right,Up or Down arrow keys). I have changed the default keys to (super + Left,Right,Up and Down arrow keys) so they don't collide with my editor but after the reboot, Ubuntu changes are somehow reverting to default. This keeps comming again and again. i am sure there is a way out so therefore need help with that...

  • HTML5 Doctype Support

    - by Metropolis
    Hey Everyone, For a long time I have been using XHTML1.1 because I thought I was cool (yeah right). However, today I read Ian Hickson's Article about how everyone uses the wrong MIME type with XHTML and it opened my eyes a lot. I happen to be one of those people who are serving XHTML with text/html MIME, because like a lot of people, W3C says its "ok" to serve it this way. At the top of that article he says that "now" he would serve it using the HTML5 doctype (!DOCTYPE HTML). What are your thoughts about doing this? If I did not use unsupported functionality, would it be ok? What would the MIME type be in this case? Thanks for any help, Metropolis
