• Choices in Architecture, Design, Algorithms, Data Structures for effective RDF Reasoning and Querying in a Big Data Environment [on hold]

  - by user2891213

  As part of my academic project I would like to know what choices in Architecture, Design, Algorithms, Data Structures do we need in order to provide effective and efficient RDF Reasoning and Querying in a Big Data Environment. Basically I want to get info regarding below points: What are the Systems and Software to get appropriate Architecture? What kind of API layer(s) would we need on top of the Big Data stores, to make this possible? The Indexing structures we will need. The appropriate Algorithms, and appropriate Algorithms for Query Planning across Big Data stores. The Performance Analysis and Cost Models we will need to justify the design decisions we have made along the way. Can anyone please provide pointers.. Thanks, David

• Any chance for fully working X1600 PCI-E ID 71c3/Unity under Ubuntu 12.04?

  - by user74975

  How can I get Unity working under an ATI Radeon X1600 PCI-E on Ubuntu 12.04? I'm rather Windows guy, but I can do some things with CLI. ATI seems to have ended support for this card for both Windows and Linux. Theres no proper driver in jockey; binary driver from Software Center doesn't give Unity, just Unity 2D. Yes, I've tried the commands from this post - without any positive results; should I try installing drivers manually?

• How do you ensure consistent experience across multiple graphics cards (or even driver versions)?

  - by Grigory Javadyan

  So I was writing a simple 2D game with OpenGL and SDL and had this problem when there was awful tearing when running in windowed mode (even though I explicitly asked SDL_SetVideoMode to use double buffering). Didn't worry about it all too much because most of the time the game grabs the entire screen, windowed mode is just for debugging. Anyway, yesterday I updated my nVidia drivers and tearing disappeared, the game runs smooth and looks nice in windowed mode too. I can see how the problem may be in the graphics driver, but this leads to a question. Obviously, professional game developers have to deal with a lot of different hardware/software configurations. What are the techniques they use to make sure the game looks the roughly the same on different graphics cards or even the same model of graphics card, but with different driver versions?

• Certifications needed to get an interview with no experience and no degree. [closed]

  - by Joel Cornett

  Possible Duplicate: Are certifications worth it? Given that I have no commercial experience to speak of -- and no undergraduate degree -- how can I best demonstrate my programming ability in order to interview for a job? How valuable are the various software certifications? Should I get the OCA? Should I submit samples of my code? Are there some other skills that I should develop? (I picked up Python and Java fairly quickly--a matter of weeks, actually.) I am a undergrad working on a triple major in math, stat and econ. I consider myself proficient with Python and have a working knowledge of Java.

• reinstalling totem 3.0.1 from source

  - by user1537727

  I have totem 3.0.1 installed on my system, but I wish to install from source the same and when I do so i am presented with the following dependency errors. How can this be possible? configure: error: Package requirements ( glib-2.0 >= 2.27.92 gio-2.0 >= 2.27.92 gtk+-3.0 >= 2.99.3 gdk-x11-3.0 >= 2.99.3 gmodule-2.0 totem-plparser >= 2.32.4 gstreamer-tag-0.10 >= 0.10.26 cairo) were not met: No package 'totem-plparser' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables DEPENDENCY_CFLAGS and DEPENDENCY_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

• Will the world depend less of developers?

  - by nmiranda

  Hi everybody, yesterday I had a little chat with a friend that is in the field of development as I am. And he told me that he planned to change of business, I mean, he wants to get off developing cause he doesn't think that it has future. "There will come days were you could have a job as a developer but you would never get rich" he said. "Nowadays is more important to have an idea and develop it in a product than being a software developer. Today you can find a lot of applications that can help you to make it. We have already non-sql databases, better cases than 10 years ago and other tools much of them free, everything is directed to depend less of developers and you'll see it more 10 years from now" Do you agree with that?

• How to bridge the gap between university and job requirements

  - by user1762636

  I study physics and computer science and both studies include minor programming tasks whereas larger tasks are only (potentially) a part of larger projects like for your thesis. When I look at job postings for scientific jobs e.g. in the area of HPC they usually ask for "extensive programming skills in C/C++ and HPC" or the like. This is what I would like to achieve, but frankly I don't know how. I don't mean to mourn, but you can imagine that studying physics/CS means having a busy schedule so I couldn't even work part time as a research assistant to get practice without negative influence on my grades. The second problem is that I lack ideas on what to code in my spare time. I would like to do something useful but even for open source projects you apparently need a whole lot of time and depending on the type of software a lot of experience to be useful. I would be grateful for any advice you can give me.

• How to have a PHP web site that can play videos offline?

  - by greco

  Our client asked to implement a system with web technologies and the basic functionalities of: We have 3 users: Admin, User, Visitor. provide videos with an indexing system. Videos and other info about them are uploaded from an admin panel. Users can make playlists, add extra info to videos etc. Visitors watch playlists, videos, track their progress etc. This are some of the very basic functionalities of the system, just to get an idea. So we agreed it's a saas project and we started with php,symphony,jquery,requireJS etc. Now our client says that he wants the user and visitor part has to be accessible offline only. He says the user can download the videos and software, and continue offline. What are your suggestions on this? Provide the ability for the user to download a local server, or another way?

  I'm a Microsoft Stack(ASP.NET, C#) developer. Mainly, I develop server side software, windows services, restful apis etc. My client side interaction is really really low.

My language list is: Scala (Powerful usage in Twitter) Go (Getting popular and channels are pretty awesome) Erlang (Stable server side programs. Used at Whatsapp) You can give advice for the above or you can give me a better option. My only exception is Objective-C. I don't want to get in that one. Thanks

• SIP clients not working on Ubuntu 12.04

  - by Xlearner

  I am trying to find a SIP client that works on Ubuntu 12.04. I have an account on voipdiscount (www.voipdiscount.com) and 12voip (www.12voip.com) Earlier on Ubuntu 11.10, I was able to use SIP clients: Twinkle, SFL Phone. Using these clients, I was able to access my account and make the phone calls to different destinations. But after I installed 12.04, Twinkle, SFL Phone and Ekiga stopped. Whenever I try to make a phone call using one of these software, for some reason they are not able to register. They are failing. Any suggestions as to what I can do? Is there any SIP client that works on Ubuntu 12.04? Thanks!

• Installing Silverlight applications without the browser involved

  One of the features we are introducing in Silverlight 4 is a silent install mechanism for out-of-browser applications. Currently every out-of-browser application (trusted or not) starts from an in-browser mechanism. In some instances where you want to deploy the app via managed desktop software or perhaps via CD-ROM, you dont want to have to tell the user to start on an HTML page first. Now Im not going to write here about the merits of why you might want to do this other than to point out what...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Is client-side HTML5/JavaScript too lame after you've worked on server-side C++/Java?

  - by stackoverflowuser2010

  I'm an experienced C++/C/Java/C# research software engineer and have worked on large-scale server systems, including huge map-reduce and database systems. Now I've been offered a new job working with client-side mobile technologies involving Javascript and HTML5 as well as some very minor native iPhone and Android programming. So, question: If you've ever made this kind of jump, did you find find Javascript/HTML too lame after you've been working on "hard-core" C++ and server systems? Did you find it challenging? Did you get bored?

• Is How the Company Makes Its Money One of The Most Important Determining Factors in their work environment, culture, etc

  - by programmx10

  This is a viewpoint I've started to realize recently about some companies that I have worked for. They had their own software product that they developed in-house but most of the focus was on building an in-person sales team to push their product to businesses throughout the country. I figure that companies that are exclusively "online", meaning that their revenue source comes from online transactions where there is no "face" of the company to the customer would have a different work culture. Just curious if anyone has worked for both types of companies and notices a difference. I myself am hoping to get more into contract programming and figure that companies that don't have to employ a sales-force and things like that would be more focused on technology and maybe even willing to be flexible on partial telecommute, etc

• programming can be taken as specialization - but what will I do still unclear [closed]

  - by C4CodeE4Exe

  I am bit confusing about my goals although whole motivation thing is $$$ but still there is something pushing me to pursue higher studies(being frustrated from boot-licking attitudes of peers and lottery system here in India for promotions,pay hikes and onshore opportunities). I am afraid I do not have any goals.I am software developer mainly in JAVA, but an ECE graduate.I want to work in programming languages. My problem is that I am not even Jack of all trades.I have experience in programming and thats where I am good(self-pro-claimed or atleast people say this treating them as a critics). I have decided to go with the wind and applying for programming languages as my specialization.But I know how to code,write test cases,how Perosnal and commercial IT insurances solution works.What I do not know is how to show that what I will do during my masters.I have no idea about what to showcase, how would my work ex will help me. totally oblivious thoughts... thanks waiting for replies....

• Can I make Launcher icons dark/dim unless app is running (then in color)?

  - by Greg

  To improve visibility of what Launcher-Applications I have running (instead of relying solely on that small right-facing triangle), is it possible to make Launcher-icons default to a black&white/dark/dim state? And then when a launcher-icon is clicked (or the super+# shortcut used) that icon would gain color and backlight signifying the app is running? If the Launcher icon's app is not running, it is dimmed out. If the icon's app is running, it is showing in color and backlit. I'd prefer an "inhouse" solution as opposed to having to install additional software, but I'm interested in hearing all options for if this is possible.

• attempted WUBI install corrupted Vista

  - by oliver zimmermann

  Tried to install WUBI through Google Chrome on my Vista machine. Got through the usual warning about running new software, selected "continue" and waited for a prompt about where to install WUBI. Never got one...waited about 30 minutes (computer still running fine)...decided to reboot and try again. OOOOOPS. Was not able to reboot Vista. Ouch. When I run a Vista recovery CD it tells me there is an "X:" drive on what used to be my C: drive and it cannot find a Vista install to recover. Anyone seen this ? It is making me very happy... THANKS!!!!!!!!!!!!

• Serverless Web Application

  - by Andrea Di Persio

  In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser. The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server. Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations. Anyone had similiar experience and wants to share their tricks/suggestion ? Do I need to tell my boss 'there is no future without a web server'? Regards.

• Comment les constructeurs répartissent-ils leurs dépenses pour les composants de leurs smartphones ? Un tableau interactif le montre

  Comment les firmes répartissent-elles leurs dépenses pour les composants de leurs smartphones ? Un tableau interactif le montre La firme américaine Tableau Software propose un tableau interactif qui permet d'en savoir plus sur les dépenses des firmes pour la fabrication de leurs smartphones. Si le prix moyen de la conception est assez semblable d'un modèle à l'autre, en revanche la façon dont les entreprises répartissent leurs dépenses varie de l'un à l'autre, et en fonction des composants. Par exemple, Apple fait les plus grosses dépenses pour les coques de ses téléphones ; Nokia ne compte pas lorsqu'il s'agit d'objectif caméra, etc. Source :
