• Connecting to an Amazon AWS database [closed]

  - by Adel

  so I'm a bit overwhelmed/bewildered by the whole concept of networking/remote-desktop , etc. The context is that - in my company I need to access a remote database. The standard way I use is to first connect using a VPN-Client( called Shrew Soft Access manager), then once that says: "network device configured tunnel enabled" I'm good to connect using windows "Remote Desktop Connection" . But now our company set up an Amazon AWS database, and I'm told I need to connect, and I ony need to use RDP. So I tried the standard windows one - but it doesn't work. On wikipedia , I looked up remote desktop sftware and downloaded one called VNC Viewer. but it doesn't work. Any advice/tips/comments appreciated EDIT: YAYA! I finally got a little more connected . I had to use my username as a fully qualified name: Computer: XYZ.XYZ.XYZ.XYZ USERNAME: XYZ.XYZ.XYZ.XYZ\aazzam

• Best resources to learn Game Development from a Java background?

  - by Julio

  Hi guys, I'm an enterprise Java programmer, however something I've been interested in and what got me into the whole programming thing was the idea of being able to create a game. Just wondering if anybody could offer any advice, or book recommendations. The side I am most interested in is game engine design and implementation. People may say "ahh but plenty exist why write your own" - its purely for learning purposes, seeing how things work and so on. So far I've taken a look at LWJGL, but achieved nothing too serious. Thanks.

• fix pavucontrol Alsa mixer with creative card

  - by schwiz

  I have been desperately trying to get my creative x-fi soundcard to work with my 10.10 install and I am almost there! I have 1 speaker working and when I open volume control I see that my device is Creative X-fi (Also mixer). However, it appears to be stuck on mono. When I open pavucontrol I get a message that says Connection failed: Connection refused and it exits. Before it closes I can see that playback is set to mono but it won't let me change before it closes. Can someone help me over this last hump? I am running 32 bit 10.10 any advice is much appreciated.

• I need to go from Linux to VS2012 fast. Anybody have a guide?

  - by Mikhail

  I need to parallelize a library through the use of a graphic accelerator. I have had no trouble doing similar work on Linux but I am struggling with using Visual Studios 2012. I can't figure out how to do analogs to simple things. I can't figure out how to do simple things like specifying linkage, libraries, and include files. I need to move quickly from understanding the Linux build system to the Windows build system. Does anybody have a guide or some advice on moving from Linux to Visual Studios development? I feel like I am crawling through a labyrinth of menus. With frequent dead ends saying that this feature has moved to another place. Also this code must build with VS2012.

• Google Cloud Messaging (GCM) for turn-based mobile multiplayer server?

  - by Chris

  I'm designing a multiplayer turn-based game for Android (over 3g). I'm thinking the clients will send data to a central server over a socket or http, and receive data via GCM push messaging. I'd like to know if anyone has practical experience with GCM for pushing 'real-time' turn data to game clients. What kind of performance and limitations does it have? I'm also considering using a RESTful approach with GAE or Amazon EC2. Any advice about these approaches is appreciated.

• Remote Desktop Viewer Set-up for 12.10

  - by Sir Linuxalot

  How do you set up the Remote Desktop in 12.10? I've scanned the available answers here and didn't find anything that answers the question considering the 12.10 interface. Specifically, advice says to check the "Allow Others to Control Your Desktop" and an IP will pop up (10.04 I believe). But when checking this in Quezal no IP shows. So how would I connect to my desktop from somewhere other than the local network, like say a coffee house? I also see this Remmina client program but have no idea if I need to use that as well. Can someone give me a step-by-step or point me to one that I haven't found yet? Thanks.

• Thomson TG782T ADSL2+ modem loses network connection

  - by squashbuff

  I am using an ubuntu 10.04 server (running on a Lenovo Thinkpad notebook) as my webserver. It is performing well in terms of handling the traffic etc. However my internet connection is ADSL2+ (using Thomson TG782T modem-router) and if the modem is reset, then my server loses network connection. The networkmanager icon shows a red exclamation mark showing that is has no connection. But as soon as I click on it and tell it to connect to eth0, the connection is back on. It must be something that networkmanager is failing to do and because of this, the reliability of my webserver is suffering. Any advice on how this can be fixed?

• Real-time chat in Ruby on Rails

  - by Skydreamer

  First, I'm sorry because I know this question has been asked many times but I'm still looking forward to finding the answer to my problem. I'd want to implement a Real-time chat for my Rails app but I can't really host the server which handles the sockets. I've tried Faye but it needs a server. I've also heard of pusher but it's limited to 20 users at a time on the chat and I can't really be sure they won't be more. I've thought of irc but I think I can't really embed it into a rails app, maybe it needs sockets... So here's my problem, can I implement a real-time chat without owning a server ? What can you advice me ? Thank you for your answers.

• How can I install the latest version of libmtp?

  - by coversnail

  In the latest version of the libmtp library there are fixes for my Android device so I would like to install the latest version I'm just not sure how! I would assume that this would pushed into the official repositories at some point, so the smart advice would probably be just to wait, but I would like to know how to do this myself if anyone could tell me. I'm currently using Ubuntu 12.04 and am running libmtp-1.1.2, the latest version (libmtp-1.1.3) has recently been released and the tar.gz file is downloadable from this direct link: http://downloads.sourceforge.net/project/libmtp/libmtp/1.1.3/libmtp-1.1.3.tar.gz How do I install this? Thanks for any help.

• Designing an API on top with Java RMI and Rest APIs

  - by user1303881

  I'm working on the backend of a java web application. We have a document repository (Fedora Commons specifically) where we house xml files. I want to abstract the API of the repository internally so that we aren't tightly coupled to one product. I'd also like to give the flexibility of connecting to to a repository via Java RMI or REST APIs. I was hoping to get advice or resources on how to implement something like this. My thought it that I'd have some abstract repository class that had methods like getRecord, updateRecord, and deleteRecord. In the constructor I would pass the URI for the repository and the API method and port. This would allow some flexibility in the future so that if the REST api became more practical, but allow the flexibility or using RMI which could (should?) have better performance. Am I over thinking this or am I on the right path?

• After how much line of code a function should be break down?

  - by Sumeet

  While working on existing code base, I usually come across procedures that contain Abusive use of IF and Switch statements. The procedures consist of overwhelming code, which I think require re-factoring badly. The situation gets worse when I identify that some of these are recursive as well. But this is always a matter of debate as the code is working fine and no one wants to wake up the dragon. But, everyone accepts it is very expensive code to manage. I am wondering if are any recommendations to determine if a particular Method is a culprit and needs a revisit/rewrite , so that it can broken down or polymophized in an effective manner. Are there any Metrics (like no. of lines in procedure) that can be used to identify such segment of code. The checklist or advice to convince everyone, will be great!

• What is the most effective order to learn SQL Server, LINQ, and Entity Framework?

  - by user1525474

  I am trying to get some advice on what order I should learn about SQL Server, LINQ, and Entity Framework to be able to better work with ASP.NET Webforms and MVC. From what I've been able to learn so far, many recommend learning LINQ or Entity Framework before learning SQL Server. It also appears that many companies are looking for people with knowledge in LINQ-to-SQL and Entity Framework without mentioning SQL Server. However, my understanding is that LINQ-to-SQL and Entity Framework translate code into SQL Server queries, making this a poor approach. Is there a correct or best order in which to learn these technologies?

• Multiple domain names with pages linking to one website

  - by Mark Ravenhill

  Hello, I work for a company who have been redesigning their company website. I have been asked to register loads of domain names that contain the keywords that they want to use on the original site. Each of these domain names will contain a one page website with a destription of what the company offers and a link saying something along the lines of 'click here for more infmormation' which then takes you to the main site. The idea being the main site will then be recieving a lot of inbound links and hopefully rise in the google rankings, not to mention bring in more customers who have come to the site from all the other domain names who wouldn't have normally got to the website because it wasn't ranked on the first page. Is this a good idea or will Google see this as spam and penalise the main site for having loads of links to it from one page websites hosted on the same nameserver? Any advice would be greatly appreciated. Thanks, Mark.

• Ubuntu One under KDE

  - by Andy Goss

  Currently, while Ubuntu One can be installed under KDE, Dolphin does not know about it, so it cannot set folders other than Ubuntu One to sync. There is a command line utility, "u1sdtool", which performs most if not all the functions you need. Setting the keyring password to be the same as your login won't prevent Ubuntu One asking you for it again on login. If you want to change it, install Seahorse, look for it in your menus as "Passwords and Keys", and right click over "Passwords: default", then select "Change Password". The various deleting tricks I've read about don't work for me. There is an ubuntuone-client-kde being developed, but no clue as to when it will appear in a stable repo. Any further advice will be welcomed by me and doubtless a few other KDE users.

• Where to store shaders

  - by Mark Ingram

  I have an OpenGL renderer which has a Scene member variable. The Scene object can contain N SceneObjects. I use these SceneObjects for storing the vertex position and any transforms. My question is, where should shaders be stored in this arrangement? I guess they need to be in a central location because multiple objects can use the same shader. But then each object needs access to the shader because it needs to set attributes into the shader. Does anyone have any advice?

• Does your company name in an article title damage Search Engine relevance

  - by user492681

  I've been wondering about this for a while but never come across a solid answer. Many websites include their name in all the title tags of their articles. This is often apparent in word-press blogs etc. eg: Tsunami hits Japan and leaves thousands homeless | My Website Name The issue I have is that Search engines strip the stop words out of this sentence to leave the words in which it compares to the body text. So if I want my article to rank well and be relevant, in this case about the terrible Tsunami that has recently struck Japan what is to STOP the MY WEBSITE NAME section of the title de-valuing the relevance of the article. Am I over-worrying? Or should I take this in to consideration? Thanks for advice in advance.

• Protect js code from being stolen

  - by Kaidul Islam Sazal

  I have developed an web app with jquery,html-css markup which would be an premium web app. So I have to ensure the security of the code from being stolen.But as all these are client side,so there is no 100% secure way to protect them.But I want to make them harder to steal.For this I did : I have disabled the right click button of mouse I have minified and obfuscated the code. I have used js code to add external js file and obfuscated the code so that none can understand the name of the external js file I have created a index.html file in the js folder so that none can get access the js folder Do you think all these are enough to make stealing harder? Or any suggestion/advice for me?

• Learn a NoSQL or become a badass with traditional RDMS - Where is/will the work be?

  - by beck

  I'm half way through my MSc and am thinking about my dissertation which I get 3 months to work on full time. Im very comfortable with the traditional Relational Database, the question is should I work on a project where I get a good understanding of something like Cassandra, or should I really push my RDMS knowledge to the limit. Getting great at something like MySQL is a solid safe option, will there really be much work for me with Cassandra in my tool belt? I would love to do either.... Thanks for your opinions and advice.

• Building a chat-like functionality in iOS

  - by Mani BAtra

  I was planning to implement a functionality wherein a user can send data to a friend of his, similar to sending messages in WhatsApp. This is how I broke down the problem : The user registers for the app. This equates to user info being stored on a dedicated server. With the phone number as the key identifier. The user selects the friend to send a message to and pushes the data. The receiver polls the server regularly and acknowledges that the data has been received. I did a little bit of research and am thinking of implementing this using the XMPP Framework for iOS. Any pointers as to is this the correct implementation or some advice in general?

• MathType and LibreOffice Math comparison

  - by Agmenor

  In my office my team and I are going to type texts in the future which will include mathematical signs. Two programs are being proposed: LibreOffice Writer + Math or Microsoft Office + MathType. I would like to advocate for the first solution, but I need to know what technical advantages and disadvantages each program has. Compatibility with Ubuntu is an evident and important characteristic for LibreOffice, but could you give some other aspects? As a side question, do you advice any other program, even if not WYSIWYG and thus not my preference in this case?

• How to monetize and/or protect framework rights?

  - by Arthur Wulf White

  I made a game engine/framerwork for ActionScript 3 that allows very efficient and flexible level design for Platformers, Tower Defense game, RPG's, RTS and racing games. The algorithms I used are new and are not available in any other level editor I've seen. What are the best ways to benefit myself and others with my new framework? It is written for ActionScript 3 so unless I translate it to C# I'm guessing it will be decompiled and used by others. I want to have some lisence, allowing me to share the framework and still benefit from it. Any advice would be appreciated. This issue has been on my mind a lot this year. I am hoping to find a solution that will bring me some relief.

• Adding 'swerve' to a direction

  - by Skoder

  Hey. I'm not much of a maths expert, so this is probably quite straight forward. I was playing a soccer flash game where you take free kicks. You provide Power, Swerve and Direction. I'm reading up on vectors and such so I can use the direction and power information to shoot the ball with the correct velocity. What I don't understand is how the 'Swerve' information is used. What formula connects the Swerve information with the Direction and Power? (This is all in 2D) Thanks for any advice.

• SQLPass NomCom election: Why I voted twice

  - by Hugo Kornelis

  Did you already cast your votes for the SQLPass NomCom election ? If not, you really should! Your vote can make a difference, so don’t let it go to waste. The NomCom is the group of people that prepares the elections for the SQLPass Board of Directors. With the current election procedures, their opinion carries a lot of weight. They can reject applications, and the order in which they present candidates can be considered a voting advice. So use care when casting your votes – you are giving a lot...(read more)

• Acer Aspire installation of Ubuntu as the one and only OS

  - by Anthalis

  I am quite sick of a Win7 limited edition that was pre-installed on my Acer Aspire One 533. I want to have Ubuntu as the only OS on this little thing. I have tested Ubuntu on a pretty unstable system and I am simply in love with it, despite the fact that I am still on the learning path. So my questions is how do I format/erase all previous info, including windows files? I am interested in a real cleanup of the drives rather than just a re-partitioning, because I travel every now and then and I want to prevent any personal data remaining on the drives for anyone with recovery knowledge to sniff through. Thanks in advance for your input and advice. A.
