• Artist, Looking to lean how to program games, where do I start? [on hold]

  - by Christopher Hindson

  I have bean an artist for many years now I am very comfortable with using Photoshop and Flash but I want to learn how to but together my own games, I bean doing my own research into this and at the moment I am at little bit stuck on witch direction to go down. So my question is witch programming language should I learn? I have already bean looking into this what i understand is that Gamemaker with its built in language (GML) is one of the most friendly to people who are new to the game making world. I have played around with this program and was pretty happy with it but I want more also you can use Unity with language such as C and javascript and then games built with Java witch looks interesting. One more thing before you send your answer in at this moment in time I would only be able to make 2D game but 3D isn't out of the picture.

• ubuntu 12.04 nvidia breaks resolution

  - by Terje Kristiansen

  i am running ubuntu 12.04 64-bit and i have a nvidia Geforce GT 650m, it was running fine with 1920 x 1024, except a lot of tearing everytime i ran videos. I thought activating the nvidia driver maybe would fix this. When entering "nvidia X server setting" it says " you do not appear to be using nvidia X driver. Please edit your X configuration file ( just run "nvidia-xconfig" as root), and restart the X server. I did and then the computer reboots with a resolutioin of 640 x 480. How can i restore the previous settings, or preferably get it to show full resolution without tearing ? When i enter "nvidia X Server Settings" now it still says the same as above, " do not appear to be using nvidia X driver" when i go to "system settings, additional drivers" it says nvidia_current -- "This driver is activated but not currently in use" astr0

• Could someone help me understand SQL TDE Database encryption?

  - by SLC

  I don't quite follow how it works. According to the MSDN Article there is a big hierarchy of keys protecting other keys and passwords. At some point the database is encrypted. You query the database which is encrypted, and it works seamlessly. If you're able to simply connect to the database as normal and not have to worry about any of the encryption from a developer point of view, how exactly is it secure? Surely anyone can simply connect and do select * from x and the data is revealed. Sorry my question is a bit scattered, I am just very confused by the article.

• Ubuntu not showing complete list of partitions while installing 10.04 and 10.10

  - by Ravi

  I am a total beginner to Ubuntu. I have tried to install Ubuntu on my 320 gb hard disk and am stuck at the partition page. The problem is, Ubuntu is not showing all the partitions. When I run the live CD and try to see all the drives these are not present. I have presently 4 drives, C: 58 GB D: 48 GB E: 87 GB and F: 102 GB. The F: drive is not shown; at the time of installing it does not show any of the drives, just a chunk of 257 GB, hence I am unable to install Ubuntu on my D: drive. On the C: drive, Windows 7 64 bit is installed.

• How are crossplatform/multiple-OS C++ projects planned in terms of code and tools?

  - by Nav

  I want to create a project in C++ that can work in Windows, Linux and Embedded Linux. How are projects created when they have to work across many OS'es? Is it first created on one OS and then the code slowly modified to be ported to another OS? Eg: to me, the Linux version of Firefox appears to be created as a Windows project and a separate Linux project with a different code base, since Firefox behaves a bit different in Windows and Linux. Although the source code download is surprisingly a single link. If QT is used for UI, Boost threads for threading, Build Bot for CI and NetBeans/Eclipse/QT Creator for an IDE, would a person be able to minimise the amount of code re-write required to get the project onto another OS? Is this the right way to do it, or are such projects meant to be created as two entirely separate projects for two separate OS'es?

• How agile methodologies can be applied in a typical " services " company?

  - by AlfaTeK

  My company is a custom software services company for external clientes, which means our typical project is one in which the contract already states the full budget of the project. Our typical project starts by defining requirements (improving the proposal high-level requirements), then we code the project, test it and ship it. We have an acceptance phase were the client tests the software and in that phase we can usually implement small changes asked by the client, or we charge extra for change requests. In some projects we have intermediate releases so the clients can check the progress of the project and give feedback on it. In summary: something like waterfall... I've followed the "agile" movement for a bit now and I always see it being a good match for a "product" company, or a company building software for an internal client. But are there good stories / advantages on using agile methods in my kind of company/projects? What are your experiences, what do you think about this?

• Ubuntu 13.10 won't boot and hangs on a black screen

  - by Anonymous John

  I installed Ubuntu 13.10 64-bit today and I sat on the internet most of the day after installation. I shut the computer down and went bowling with my family. When I came back, I turned on my computer and it came to the boot screen as usual, but then the screen went black and stayed black. Can this be solved or do I have to install Ubuntu 13.04. My dad does not know about this and I do not want to get yelled at for an hour, so I need an answer before midnight mountain time, otherwise I will install Ubuntu 13.04 so I won't get yelled at in the morning.Thanks to anyone who answers this.

• Network does not connect at boot

  - by Daniel Svozil

  I am on Ubuntu 12.04, fresh install. When I boot a machine, the boot screen says Connecting to network, later it is changed to something like Did not connect, trying for another 60s. However, the network does not connect at the boot. But I can then log in without a network connection, and if I start a network manager service manually from the terminal (sudo service network-manager start), the network is connected without any problems. Please, does anybody know where the problem could be? I don't want to wait more than two minutes every computer restart :-). I am new to Ubuntu (and also to upstart) so I am a bit lost. There is no /var/log/messages, in dmesg I found this record, though it may not be related: init: network-interface (eth1) pre-start process (492) terminated with status 1 init: network-interface (eth1) post-stop process (548) terminated with status 1 Thanks Daniel

• How to add a holding page in front of a domain

  - by Jason Bradberry

  I have set up a holding page to announce a new version of a website coming soon. I wanted people to still be able to access the original site, so my approach was to place the holding page in the root folder on the server, and move the original site to a subfolder and link to it from the holding page. However, on testing this setup it appears to have hurt the SEO placing of the website. Is there a better approach to this? I'm a bit stumped as I want both to share the same URL.

• Error while trying to dual boot Ubuntu alongside Windows 8

  - by Brian

  I recently purchased a new Toshiba Ultrabook that comes pre-installed with Windows 8. I'm trying to dual boot 12.10 with it and I have run into a problem with the installer. When I get to the page to pick the partitions I get this: No drives are listed and the only thing in that device drop down is /dev/sda. If I click Install Now or +/-/change I get an "Ubuntu has stopped working" error message. I'm trying to install off a 12.10 64-bit USB drive in UEFI mode, and I have tried it with secure boot both enabled and disabled with the same results. The hard drive set up is as follows: 500 GB main drive windows recovery (primary) EFI boot section (primary) Windows' partion (280 GB I believe) (primary) unallocated space I created for Ubuntu partition (200ish GB) another Windows recovery partition (primary) 12 GB solid state drive all unallocated space Could it be a problem with the number of primary partitions? I think I read somewhere about a max of 4.

• What 2D game engines are there available for C++?

  - by dysoco

  I just realized there are not C++ 2D Game Engines that I know of. For example, something like Pygame in Python, or Slick2D in Java. We have the following: SDL - Too low level, not a Game Engine SFML - Handles more things than SDL and it's more modern, but still not a Game Engine. I like it, but I have found it a little bit buggy with the 2.0 version. Irrlitch - It's a Game Engine, but 3D focused. Ogre3D - Same as Irrlitch Allegro - This is a Game Engine, but it's C based, I'd like a modern C++ library. Monocle Engine - This looks like what I need... but sadly there is no Documentation, no community... nothing, all I have is the Github repo. So, do you know any ? I'd like to use C++, not C#, not Java: I'm just more comfortable with C++.

• Where's the source code?

  - by Kyle Burns

  I've been contacted by several people through this blog asking about the missing source code for the "Beginning Windows 8 Application Development - XAML Edition" book (the book is available at http://www.amazon.com/gp/product/1430245662/http://www.amazon.com/gp/product/1430245662/) and wanted to share this with others who may have come to this blog looking for it but may not have communicated with me.  The publisher (Apress) does know that the source code is not posted on the book's product page and will be correcting it.  Apress is located in New York City and things were slowed down a little bit last week due to the storm, but I've been assured they will be correcting the product page as soon as they can.  Thanks to everyone who has bought the book and I especially appreciate your patience.

• How do I customize the Unity launcher for different workspaces?

  - by Srijan

  How do I customize the Unity launcher for different workspaces for Ubuntu 12.04? I am using x86-64 bit architecture running solely Ubuntu 12.04. I have searched in the community for possible aspects of this question as per the link Different Launchers for Different Workspaces? but the links provided in this doesn't address my issue as the links are outdated and it does not exactly say how to customize the launcher. Besides the environment is now buzzing with unity 5.4 and also Ubuntu 12.10. So can someone please help me to customize the unity launcher for Ubuntu 12.04 for different workspaces? Thanks a zillion in advance. Is there any features enabling customization of launcher in different workspaces in unity 5.4?

• From Transactions To Engagement

  - by David Dorf

  I've mentioned in the past that Oracle has invested quite a bit in acquiring social companies to build out its Social Relationship Management suite.  The concept is to shift away from transactions and towards engagement.  Social media represents a great opportunity to engage with customers, learn what they want, and personalize the shopping experience for them. I look at SRM as the bridge between traditional CRM and CX.  If you're looking for ideas, check out Five Social Retailing Suggestions and Social Analytics and the Customer.  There are lots of ways to leverage social media to enhance the customer experience and thus drive more sales. My friends over at 8th Bridge have just released their Social IQ report in which they rate retailers on their social capabilities.  They also produced a nice infographic so you can consume the data quickly, but I'd still encourage you to download the full report. Retailers interested in upping their SRM abilities should definitely stop by the Oracle booth at NRF in January.

• Wireless speed drops over time and doesn't get up if not reconnected

  - by Vili Lehto

  I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this? Thanks in advance.

• Updated Blue and Dark Visual Studio 2010 Themes

  I updated my previous dark theme for Visual Studio 2010 and added a new one with a blue background, similar to the background (but a bit lighter) to that of Visual Studio 2010s blue. I updated a few fonts to fit in with it and for the past week I have been using this and found that its even easier on my eyes than the dark theme. I made some changes to the dark theme, too, and include both of them in the download file here. My Blue Theme (click the images to see them larger)   My Dark...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How can I stop Ubuntu from automatically unmounting Samba shares?

  - by Billy ONeal

  I have some music files I'd like to listen to sitting on a Samba share. I added this share via the Ubuntu GUI (Places - Connect to server...), and everything worked just fine. However, despite the fact that my music file is playing from this location, after I've not touched the location using the Nautilus GUI, Ubuntu/GNOME decides that I'm not using the share anymore and terminates the connection. Thus, my music stops playing and Rhythmbox is unhappy with me. Simply clicking on the new shortcut the "Connect to server..." bit created for me immediately makes the files come back again and allows me to restart the music playing. How can I have Ubuntu not automatically dismount samba shares?

• Does google use chrome to check if a link is used by humans or just there for the bots?

  - by sam

  Does clicking a link in chrome tell google the link is used by humans and there fore not just automated backlink spam. It sounds weird but i read it today on a slightly obscure seo blog, they mensionned clicking the backlinks they make in a version of chrome where they have the "send data annonmusly to google" feature turned on. It sounded a bit far fetched but then i thought it could have a truth to it as with google now looking harder at "spammy" links it would mean at least some humans are using them. Has any one else heard anything else about this ?

• Techniques and methods to improve and speedup development

  - by Jlouro

  I just got a new project. It’s a WinForm app. And it’s interesting because I will have the possibility to learn how fish farms work and are managed. I will have to develop touch interfaces, and use datasnap to communicate and sync data between farm and office. The development will be done in DELPHI win32, still not sure about the database, but maybe SQLlite. So now comes the difficult part of the project, building it. I am just finishing one. It took me a lot of time to do it and I am a bit “burned out”. I will have time to relax, not much, but a few days. What I am looking is some tips and tricks and possibly tools to be able to speed up the development. It must be up and running in 2 months. So what tricks do you use to speed up things?

• Parallel.For Inconsistency results

  - by ni Gue ???

  I am using VB.net to write a parallel based code. I use Parallel.For to generate pairs of 500 objects or in combination C(500,2) such as the following code; but I found that it didn't always generate all combinations which should be 124750 (shown from variable Counter). No other thread was runing when this code was run. I am using a Win-7 32 Bit desktop with Intel Core i5 CPU [email protected], 3.33 GHz and RAM 2GB. What's wrong with the code and how to solve this problem? Thank You. Dim Counter As Integer = 0 Parallel.For(0, 499, Sub(i) For j As Integer = i + 1 To 499 Counter += 1 Console.Write(i & ":" & j) Next End Sub) Console.Writeline("Iteration number: " & Counter)

• Placing of copyright notice in source code

  - by Diana Dcn

  I'm about to release a project of mine that I'm really proud of under the GNU GPL and I have some questions: Should one attach a copyright notice on each and every source code file from their project? I think it's a bit ridiculous to claim copyright on a 3 line abstract class. Should I attach a copyright notice only to really important source code files? Can I not attach the whole standard thingy? Because it's big and bulky and gets in the way... If so, is the variant below ok/enough? Copyright year firstname lastname.
