• What is the situation about OpenGL under Ubuntu Unity and Gnome3?

  - by user827992

  In a GNU/linux distribution is usually installed Xorg as main graphical server, it operates with a client-server logic, a special windows is designate as desktop environment and this special windows can handle all the eyecandy stuff like decorations, icons and effects. The problem is that the latest UI heavily relies on hardware acceleration, Unity is an overlay on Compiz and the Gnome-shell also require an active driver for the GPU to work well: the problem is: on the same OS I can find multiple implementations of OpenGL who is handling my OpenGL buffer? how the OpenGL buffer is managed compared to the other windows? how can I be sure that my OpenGL implementation is glued to the hardware and is not related to the client-server logic of Xorg? For example I have tried the clutter library and I have only experienced problems under both Unity and GTK/Gnome, no problem under other OS.

• How do I access a mounted Windows share from the command line?

  - by Bryan

  Hello all, I use Places > Connect to Server... to connect to a Windows share in my work environment (requires Kerberos authentication). When I do so, I can access the Windows share via Nautilus, but I can't figure out how to access the share from the command line without using smbclient. For example, the share isn't mounted under /mnt or /media. I also looked into ~/.gvfs but that's empty as well. Is it possible to access the mounted Windows share from the command line without using smbclient?

• What are the basic skills a BEGINNING JavaScript programmer should have?

  - by Sanford

  In NYC, we are working on creating a collaborative community programming environment and trying to segment out software engineers into differing buckets. At present, we are trying to define: Beginners Intermediates Advanced Experts (and/or Masters) Similar to an apprenticeship, you would need to demonstrate specific skills to achieve different levels. Right now, we have identified Beginner programming skills as: Object - method, attributes, inheritance Variable - math, string, array, boolean - all are objects Basic arithmetic functions - precedence of functions String manipulation Looping - flow control Conditionals - boolean algebra This is a first attempt, and it is a challenge since we know the natural tension between programming and software engineering. How would you create such a skills-based ranking for JavaScript in this manner? For example, what would be the Beginner Javascript skills that you would need to have to advance to the Intermediate Training? And so on.

• High level overview of Visual Studio Extensibility APIs

  - by Daniel Cazzulino

  If your head is dizzy with the myriad VS services and APIs, from EnvDTE to Shell.Interop, this should clarify a couple things. First a bit of background: APIs on EnvDTE (DTE for short, since that’s the entry point service you request from the environment) was originally an API intended to be used by macros. It’s also called the automation API. Most of the time, this is a simplified API that is easier to work with, but which doesn’t expose 100% of what VS is capable of doing. It’s also kind of the “rookie” way of doing VS extensibility (VSX for short), since most hardcore VSX devs sooner or later realize that they need to make the leap to the “serious” APIs. The “real” VSX APIs virtually always start with IVs, make heavy use of uint, ref/out parameters and HResults. These are the APIs that have been evolving for years and years, and there is a lot of COM baggage. ...Read full article

• xmonad keyboard doesn't work

  - by Mikkel Paulson

  I'm experimenting with xmonad, which I installed from the Ubuntu Software Centre on Ubuntu 12.10. It looks cool, but when I invoke it (using xmonad --replace from the command line) my title bars disappear and my keyboard stops working. At all. The terminal stops working, the keystrokes I've seen in online "getting started" guides are ignored, and the only way for me to actually power the system off is to hit the reset button or ssh in from my phone. Ironically, my mouse still works. One guide I saw suggested replacing the default window environment with xmonad, but I'm afraid of rendering my system completely inoperable if I do that. Any suggestions?

• I'm tempted to include easter eggs in my code - will this get me fired?

  - by blueberryfields

  While working on a portion of the code for our application, I've noticed an opportunity to include one of my side projects as an easter egg. I can do this in a way which I am certain will in no way harm anyone, and I've met with a significant and representative sample of our client base - I'm certain that those who have the knowledge and skills required to find the egg, will also find it humorous. How likely is it that I will get fired for including an easter egg in our application? For more context, the application is aimed at enterprise clients, and, while the users of it tend to be technical, geeky and will enjoy the egg, those in charge of purchasing are on the sales/marketing side of things. I can't even begin to guess how they would react. Edit: Yes, I've asked my manager. As you might expect in a corporate environment, the answer was: "I cannot condone this. You're on your own"

• How can I convert an image from raw data in Android without any munging?

  - by stephelton

  I have raw image data (may be .png, .jpg, ...) and I want it converted in Android without changing its pixel depth (bpp). In particular, when I load a grayscale (8 bpp) image that I want to use as alpha (glTexImage() with GL_ALPHA), it converts it to 16 bpp (presumably 5_6_5). While I do have a plan B (actually, I'm probably on plan 'E' by now, this is really becoming annoying) I would really like to discover an easy way to do this using what is readily available in the API. So far, I'm using BitmapFactory.decodeByteArray(). While I'm at it. I'm doing this from a native environment via JNI (passing the buffer in from C, and a new buffer back to C from Java). Any portable solution in C/C++ would be preferable, but I don't want to introduce anything that might break in future versions of Android, etc.

• Are "Compile to JavaScript" Frameworks Hostile to Continuous Integration?

  - by joshin4colours

  Lately we've been looking at ways to improve automated testing and related tooling of our enterprise-level GWT web app. I've realized that in some ways, GWT is a bit hostile to automated testing, mainly because of the nature of the long GWT compile times from Java to JS. This makes unit testing somewhat challenging, but it also puts some roadblocks up for testing in a CI environment. I've also found out that some of our build and deployment processes are somewhat complicated due to the nature of GWT's compile process. Is this a general problem for "compile to JS" frameworks for webapps? I don't have much experience with them, but I can see some potential problems for automated testing and continuous integration and deployment. Some issues I see: Long build and compile times preventing quick deployments Language the app is developed in != JS, preventing good unit testing Obfuscated JS in the actual app makes it more like a executable than a web app Are these issues present in other similar frameworks, or is this more a GWT issue?

• wrong GNOME logo at startup after 12.04 upgrade

  - by swordfish

  I'm not too expert of Ubuntu, but after a quite painful upgrade to version 12.04 (from 11.10), which first required to reinstall wireless drivers in order to work properly, and after an update from the Update Manager that I ran soon after the upgrade, I have a very strange problem coming up: at login page, where you choose your user among the list of the available ones, I can also see the list of available IDEs (Gnome, Gnome classic, Unity, Unity 2d, etc) but the funny thing is that the classic "foot" logo normally associated to the GNOME selection has now disappeared, and instead the "gear" logo (the one normally related to Unity, is on the side of the "gnome" choice. Note that the foot logo remains associated to the Gnome Classic item, and that the "gear" logo is still associated to the various versions of Unity available. This is not serious, since I can still access my GNOME or Unity environment, but I wonder if I can fix this up.

• Is Java much harder to "tweak" for performance compared with C/C++?

  - by user997112

  Does the "magic" of the JVM hinder the influence a programmer has over micro-optimisations in Java? I recently read in C++ sometimes the ordering of the data members can provide optimizations (granted, in the microsecond environment) and I presumed a programmer's hands are tied when it comes to squeezing performance from Java? I appreciate a decent algorithm provides greater speed-gains, but once you have the correct algorithm is Java harder to tweak due to the JVM control? If not, could people give examples of what tricks you can use in Java (besides simple compiler flags).

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• Services or Shared Libraries?

  - by Royal

  I work in an environment where we have several different web applications, where each of them have different features but still need to do similar things: authentication, read from common data sources, store common data, etc. Is it better to build the shared functionality into a set of services, to be called by the web apps, or is it better to make a shared library, which the webapps include? The services or libraries would need to access various databases, and it seems like keeping that access in a single place (service) is a good idea. It would also reduce the number of database connections needed. A service would also keep the logic in a single place, but then it could be argued that a shared library can do the same thing. Are there other benefits to be gained from using services over shared libraries?

• Locate a user's bashrc file

  - by Starkers

  Really confused. Upon running cat etc/passwd I have found this: postgres:x:117:126:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/bash meaning I have a postgres user, right? I want to change the bashrc environment file of this user to make commands available to it. /var/lib/postgresql doesn't contain a bashrc file, and /bin/bash doesn't contain it either, so I don't really know what's going on. All I know is a created postgres using the useradd command, so why do I have some weird user with no home directory? So confused :(

• How do I install Java?

  - by Jay

  I am using Ubuntu 11.04 Natty Narwhal. I recently installed openjdk-jre6 because one of the websites I use requires java for me to log in. Unfortunately, even after installing openjdk-jre6, I am not able to use the website. In place of 2 text boxes where I am supposed to enter my username and password, it simply shows a message "click here to download plugin". I am using Firefox by the way. I even tried to install java by clicking on that message. But it says "Java Runtime Environment not available". And then gives me a button to install java manually. But I would rather install it from the repo's. Could someone please tell me, what I should do to get Firefox to take note of the openjdk-jre6 that I have already installed?

• BizTalk 2009 - Messages: Last 100 Sent

  - by StuartBrierley

  Having previously talked about the lack of the traditional HAT in BizTalk 2009, the question then becomes how do you replicate some of the functionality that was previsouly relied on? I have already covered the Last 100 Messages Received query so what about sent messages? In BizTalk 2004 we had a query in HAT to return the messages sent in the last day.  While not a direct replacement the following query replicates some of the usefullness of this query in a BizTalk 2009 Hatless environment. Basically we are creating a query to search for the last one hundred tracked messages that were sent by BizTalk: Coming up Messages - last 50 suspended Service instances - last 100
