• Connecting with a BSNL Broadband Internet

  - by user10026

  I am not able to connect my broadband connection with ubuntu and it doesnt work. The connection works fine when I use Windows7 but when i use ubuntu I am not able to access the internet. I followed various steps mentioned in various sites and still could not find a solution. I have installed ubuntu 8.04 in my system. The interface eth0 is not at all detected and when i use the menu system-administrator-network I am not getting an option for wired connection. Just the Wireless connection and Point to Point connection tabs are available.. It's really urgent.. I'll be very happy if u guys can propose to me a working solution to deal with this problem..

• How do I get a Realtek Wireless USB Airlink101 AWLL5088 working?

  - by Tobias_Mann

  I am running Ubuntu 11.10, 32bit. I ordered them a Realtek Airlink101 AWLL5088 based upon the relative ease for linux installation. I am having trouble installing the drivers. I copied the drivers to /usr/src/ and ran sudo ./install.sh from that director listed above. I have tried ndiswrapper, and allowing the default drivers, but with no luck. It seems to continue to try and use the default free drivers, even though I have blacklisted them using the guide described here. There was no error, I was asked which card I was using. I looked at the packaging and at the support page, and guessed number 2, allowed to finish, and rebooted. It continued detect the wireless network after the reboot, but would never complete the connection. I would appreciate any feedback. I am kind of stuck trying to figure this out.

• How to create website shortcuts on the desktop / in a folder using Chrome?

  - by it's me

  Help with something really basic, which I am unable to figure out. In Windows creating a shortcut (link) for a website is as easy as dragging-and-dropping the favicon/address bar to the desktop or a folder. I tried the same in Ubuntu (Chrome browser), but it's not working. The web page is being saved as a file, but not as a link/shortcut. Am I missing something or is there no way to quickly create shortcuts to web pages/web sites without installing some app for that? If the above is true, is there an app that does what I need? I hope I am clear enough.

• How do you balance between "do it right" and "do it ASAP" in your daily work?

  - by Flot2011

  I find myself pondering this question times and times again. I want to do things the right way, to write a clean, understandable, correct code that is easy to maintain, but what I really do pretty often is writing a patch upon patch just because there is no time, clients are waiting, a bug should be fixed overnight, the company is losing money on this problem, a manager is pressing hard etc. etc. I know perfectly well that in a long shot I am wasting much more time on these patches, but as this time is spread over months of work, nobody cares. Also, as one of my managers used to say, we don't know if there will be this long shot if we will not fix it now. I am sure I am not the only one entrapped in this endless real/ideal choices. So how you, fellow programmers, are coping with this?

• Making a level editor for my game

  - by Sherif Maher Eaid

  I am doing a 2D sprite based game in XNA for WP7, The game logic is simple, you start at some point, you want to avoid obstacles and reach a certain goal. obviously I need to make many levels for the game to be challenging and funny. I am considering making a level editor for my game where I can be able to design the level using some kind of GUI then it translates that to a .lvl or something that the game can read and interpret that to a playable level. I am asking for an already made level editor for XNA/WP7.

• General usage question of vbo

  - by CSharpie

  Firstofall, I am sorry if my question is to broad. I am developing a tile based game and switched from those gl.Begin calls to using VBOs. This is kind of working allready, I managed to render a hexagonal polygon with a simple shader applied. What I am not sure is, how to implement the "whole" tile concept. Concrete the questions are: - Is it better to create 1 VBO for a single tile and render it n-Times in every different position, or render one huge VBO that represents the whole "world" - Depending on the answer above, what is the best way to draw a "linegrid". Overlay with the same vbo using the respecting polygon.mode , or is there a way to let the shader to this? - How would frustum-culling or mousepicking work then, do i need to keep the VBO-data in memory?

• What do Embedded Software Developers do on a day to day basis?

  - by afree100

  Edit: I am not asking how to program embedded systems. I am asking how it is done in a practical business setting. I have searched for hours for information on what software developers actually do. More specifically, what coding challenges would one experience daily (e.g. code examples (although obviously not too large), specifics)? I am interested in Linux based embedded systems mainly, but any software development would be helpful (in the C/C++/Assembly areas). Also, regarding this, a distinction between junior, intermediate and senior developers would be helpful. Also, what is the best place to prepare for such things before getting a job for the first time?

However, I am running into problems when the command sudo dpkg -i steam.deb && sudo apt-get install -f. I get the message that the version of Zenity is too low. The minimum required version is 3.4.0-0ubuntu4 while I currently have 3.4.0-0ubuntu2 I tried sudo apt-get install zenity but it does not update it and gives the following message: zenity is already the newest version. I also tried installing via the ubuntuupdates website for the latest version of Zenity, but it still does not work.Ubuntu Software Centre indicates that it is already installed and provides no option to update. :( Any idea how to update Zenity in my system?

• Preparing for Interview: I feel like, I wanna start coding all data structures again.... Is it a right way to start?

  - by howtechstuffworks

  I started preparing for my interview. I will be graduating this May. Right now, I am doing an internship in an product based company, so I did my fair share of preparation. The thing is, whenever, I try to do something, I always think that I should start everything from page 1. It is sometimes not at all helpful.... For example, reading a programming book from page 1 is not going to helpful, as I never completed one and always stopped half way through or rushed through towards deadlines. I am facing a similar situation now. I feel like, I wanna start coding all data structures from first(I attempted and finished atleast 6-7 last fall, preparing for interview). Now I feel like, I wanna code everything from first, instead of attempting something new.... I am not quite sure, what this is, but this is the way I have been..... LOL

• Why would i need extra IP adresses from my web host?

  - by user4524

  I am moving to a new and cheaper host. My old one raised the prices suddenly by a factor 10. Now what I did not like about the old one, was that each time I set up a new website, I had to set up a new account, with the result that I have to pay for a lot of webspace and a lot of bandwith i don't use. Now I am moving over to a new host, who cheaply offers virtual servers. Now I am a n00b when it comes to server tech. I have two questions about this: 1. Could I install all my webistes on this virtual server, provided it is big enough? 2. They offer the possibility of getting more than one IP address, but it costs more. What would be the advantage of this? Would I be able to suffice with one IP address?

• Can't find my DVD drive in Ubuntu 12.04

  - by user72953

  I am completely new to Linux, due to some problems in my Windows I decided to give Linux a try. I am quite liking it accept for some minor issues. The biggest of them is that I cannot find my DVD drive in Ubuntu. After I insert the disk, the drive's green light flickers and then nothing. I don't get anything on my unity bar or desktop. There is no folder inside my /dev folder which indicates a dvd drive. There is a cdrom folder in my root folder but nothing is there. If you guys know what's wrong, I'd appreciate the help. Am a complete newbie so don't expect me to know anything about Ubuntu, although I have spent lots of hours in last 2 days googling my issue so I have basic information...

• Knockback enemy based off of direction sprite is facing

  - by pengume

  Hey Everyone, Today I am trying to make it so if I hit the enemy then the enemy well be knocked backwards in the direction the sprite is facing. I am rotating the sprite around 360 degrees using a joystick on the screen and wanted to know the best practice or ways to accomplish this. I have come up with a few ideas but none of them make use of the sprites angle he is facing just a check to see if I hit the bottom then move him upward and so forth. I am just stumped on how to apply the sprites angle to the enemies x and y coordinate and move him accordingly. Has anyone tried this and have suggestions or things to look for? Thanks in advance.

• Domain Model and Querying

  - by Tyrsius

  I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

• Algorithm for Learning development

  - by user9057

  This is a fairly general question. I know a bit of Perl and Python and I am looking to learn programming in more depth so that once I get the hang of it I can start developing applications and then websites. I would like to know of an algorithm (sequence of steps :)) that could describe my approach towards learning programming in general. I have posted small questions on Perl/Python and I have recieved great help from everyone. Note:- I am not in a hurry to learn. I know it takes time and that's fine. Please give any suggestions you think are valid. Also, please don't push me to learn Lisp, Haskell etc - I am a beginner.

• Is it the job of a developer to suggest IT requirements?

  - by anything

  I am the only developer working on a web application which is nearing to its end. Now we are looking into making it Live in maybe a couple of months time. This is a web application for a non IT company. Though they have their own internal IT team, they have asked me on what will be the hardware requirements for the live servers eg. RAM, 32 bit or 64 bit. Shouldn't the internal IT team be doing this or since I am the only person working on the project is it my resposiblity to let them know of the any specific hardware requiremnts which may impact the performance of the project? The reason I am asking this question is that, I have not this before. All the times I used to be given a server and asked to deploy apps on it. I never used to worry about the server configuration etc.

• Where to start when digging into an existing J2EE codebase?

  - by Jacob Krustchinsky

  I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

• How can I calculate the angle between two 2D vectors?

  - by Error 454

  I am working on some movement AI where there are no obstacles and movement is restricted to the XY plane. I am calculating two vectors, v, the facing direction of ship 1, and w, the vector pointing from the position of ship 1 to ship 2. I am then calculating the angle between these two vectors using the formula arccos((v · w) / (|v| · |w|)) The problem I'm having is that arccos only returns values between 0° and 180°. This makes it impossible to determine whether I should turn left or right to face the other ship. Is there a better way to do this?

• How to make 8.04's screen saver enter screen into standby?

  - by Android Eve

  I am using Ubuntu 8.04 and despite using 'gnome-power-manager' to set dpms_method_ac to 'off' for backlight, the screen will not enter standby after set time. Also, "Put display to sleep when inactive for:" (via System-Preferences-Power Management) is already set to 1 minute. Interestingly enough, this only happens when I am logged in. When I am logged out, the screen does go into standby after set time. So I know it's not the screen... Any idea how make Ubuntu 8 screen saver enter screen into standby, while logged in?

• Moving a LAMP set up from 32 bit to 64 bit

  - by user10157

  Hello everyone... I have setup an Ubuntu server 10.10 32bit on an old Dell D610 Laptop for testing. I have the latest PHP, MySQL and Apache with Wordpress installed. After the testing is over and once I finish adding material to my wordpress I will build a Ubuntu 10.10 64bit VM on Hyper-V. What I am wondering is , if it's best practice to build everything from scratch (which will take me more time and would like to avoid) or transfer the database and all other settings? If I choose to transfer how and what I need to do? Here's where I'd like some help as I am still an intermediate admin (If I can call it that!) I am looking forward for your help. Thanks!

• Organizing your Data Access Layer

  - by nighthawk457

  I am using Entity Framework as my ORM in an ASP.Net application. I have my database already created so ended up generating the entity model from it. What is a good way to organize files/classes in the data access layer. My entity framework model is in a class library and I was planning on adding additional classes per Entity(i.e per database table) and putting all the queries related to those tables in their respective classes. I am not sure if this is a right approach and if it is then where do the queries requiring data from multiple tables go? Am I completely wrong in organizing my files based on entities/tables and should I organize them based on functional areas instead.

• How to generate `AllowDeactivateGrabs` in command line ?

  - by boffin

  I am using XFCE-Ubuntu and do a lot of my development work there. In my case, when I sometimes use Xilinx ISE, the mouse cursor hangs as a Grab pointer and then stops responding. The entire X environment becomes unusable and I have to kill it and restart. This is becoming a serious annoyance. I saw this bug: AllowDeactivateGrabs is broken I see that sending AllowDeactivateGrabs in command line can kill the Grab. In my case, I am doing this on a remote server, so it is the application in the remote server (over X2GO) getting messed up. I am able to login in command line and kill X. Is there a way to generate AllowDeactivateGrabs in command line ? So I dont mess up my other applications and potentially lose data.

• To track or not to track user created images for display in a dynamic website?

  - by Question Overflow

  I have a website that allows user to upload and display images. Currently, I am not using a database to track these user images. A folder having the user id as the folder name is created for each user and under each folder, the image files are labelled numerically with filenames ranging from 01.jpg to 20.jpg. Up to 20 such images can be displayed on each user page. I am using javascript to hide these images in case of any of them is absent. I have seen many websites having user images with unique random filenames and possibly tracking these files with a database Since obscurity is not something that I need for these web accessible images, is there any reason why I should track them with a DB? I am not sure if a reduction of 404 errors is a good enough reason to justify the added complexity of maintaining a database or can anyone enlighten me?

• Defaulting internet requests to wlan0 when also connected to eth0

  - by Dudemcman

  I am trying to configure an Ubuntu 10.04 desktop edition as a server. I currently have the DHCP server working through eth0. My problem is that I only have one Ethernet port, and am receiving Internet though a mobile hotspot on my phone through wlan0, and whenever I attempt to connect through wlan0 and eth0 I am unable to access the Internet through the server or the clients. When I disconnect from eth0 I then regain access. I have searched extensively for a solution, and have come up short. Any help is appreciated.

• Multiple ( V- / I- ) Buffers, is it sane?

  - by Techie

  Currently I am developing an RTS game using XNA ( / ANX.Framework ). There is one thing bothers me. I am not sure in what way or how to organise Buffers. Should I use a new Vertexbuffer for any object ( e.g. a Char, a Table, an model ) or is it better to use ONE HUGE/ BIG Buffer to store any geometry in? I am still new to 3D Programming though I finished yet couple games using DirectX 9. Well, I hope this question qin't a duplicate and I appreciate any answer leading me into the right direction.
