• Help! Installer crashing

  - by Mike

  I had ubuntu 12.04 installed on a Satellite l635. I wanted to start over with a fresh install because I had experimented with a bunch of different things, and computer was getting glitchy and random freezes. I used the same iso I used for original install, and it keeps say the installer crashed with a erron5 input/output error. Tried an older iso for 11.10 I had used in the past with same issue... To see if it was disc or computer (not a great idea) I tried the 12.04 iso on another laptop. Now I have 2 laptops with no os. Both discs however live boot on both systems. PLEASE HELP! I've searched forums and can't find the same problem.

• How to properly code in Unity? [on hold]

  - by Vincent B.

  I'm fairly new to Unity (yet I touched it and made a few proto with it) and I'd like to know how I'm supposed to work with it. I'm student in programming so I'm used to C/C++ with SDL/SFML, writing code and only using Input/Graphics/Network libs. I followed a few Unity guides and it was way more around drag & drop on scenes and a bit of scripting to activate it all, which disturbed me. So I fond a way to only use one GameObject and use a Singleton to launch code and display stuff (for 2d games at least). At the end of the day I make games not using "Instantiate" or such at all. Is it the right way ? Am I supposed to do this ? How much are your scenes populated (in a professional environment) ? When should I stop coding and start using the editor ?

• MachForm, RackForms(FromBoss), Form Tools [on hold]

  - by user39200

  This is my first question here. I am looking for a form builder solution that will allow rapid form development even by beginners, without needing much knowledge of programming. I prefer a solution that we can install on our servers. I have 3 products shortlisted for further review: MachForm, RackForms(formerly FormBoss) and Form Tools If anyone has used any of these products, I would appreciate your input on your experience with using these products and your recommendations. Does anyone know of other products that I must be sure to include in my review? We will eventually move over hundreds of forms to the chosen solution and I would like to make sure as much as I can that it will still be a viable solution in the coming years. Looking forward to everyone's feedback!

• c++ and SDL: How would I add tile layers with my area class as a singleton?

  - by Tony

  I´m trying to wrap my head around how to get this done, if at all possible. So basically I have a Area class, Map class and Tile class. My Area class is a singleton, and this is causing some confusion. I´m trying to draw like this: Background / Tiles / Entities / Overlay Tiles / UI. void C_Application::OnRender() { // Fill the screen black SDL_FillRect( Surf_Screen, &Surf_Screen->clip_rect, SDL_MapRGB( Surf_Screen->format, 0x00, 0x00, 0x00 ) ); // Draw background // Draw tiles C_Area::AreaControl.OnRender(Surf_Screen, -C_Camera::CameraControl.GetX(), -C_Camera::CameraControl.GetY()); // Draw entities for(unsigned int i = 0;i < C_Entity::EntityList.size();i++) { if( !C_Entity::EntityList[i] ) { continue; } C_Entity::EntityList[i]->OnRender( Surf_Screen ); } // Draw overlay tiles // Draw UI // Update the Surf_Screen surface SDL_Flip( Surf_Screen); } Would be nice if someone could give a little input. Thanks.

• Is server validation necessary with client-side validators?

  - by peroija

  I recently created a .net web app that used over 200 custom validators on one page. I wrote code for both ClientValidationFunction and OnServerValidate which results in a ton of repetitive code. My sql statements are parameterized, I have functions that pull data from input fields and validates them before passing to the sql statements or stored procedures. And the javascript validates the fields before the page submits. So essentially the data is clean and valid before it even hits the OnServerValidate and clean after it anyways due to the aforementioned steps. This makes me question, is OnServerValidate really needed when I validate on the clientside?

• Bad sound quality and headphones not working

  - by wifi

  Using Ubuntu 10.10, on a HP Pavilion t3019.es, which has a Realtek ALC880 soundcard. It has 6 rear jack outputs, plus digital audio input and output, plus 3 front jacks (mic, headphones and a blue one which i don't know what's for). The sound on my computer is very low, and when i raise the volume up to 50%, it starts sounding distorted, crackling. Also, the headphones don't work when i plug them (it just keeps on playing through the speakers). I tried to comment the "/etc/modprobe.d/alsa-base.conf" file according to the soundcard and jacks in my computer, but none of the lines added worked (naturally, didn't added them at once). I found out that adding "options snd-hda-intel model=generic" to it made the sound better, but it's not as good as in Windows yet. Any ideas? Other than setting the PCM value, didn't work for me. Thanks.

• Split Texture2D Across Line

  - by Simie

  Background I'm using a texture as a damage map represented by an array of floats for displaying damage effects on a space ship in a process. An upside of this is being able to 'slice' ships in half, using an input damage map with a line down the middle, as shown in the diagram below. Question However, I'm encountering problems separating this split ship into two different entities. I would like to be able to split the image down the 'damage line', in a process similar to this: I don't have much idea where to start detecting the red line above. Any advice would be welcome.

• Ubuntu Server - Virtual Box?

  - by user186144

  So I got VirtualBox just for Ubuntu Server, I'm currently Running Ubuntu 12.04 as my main OS. But when I got everything set up in Ubuntu Server 12.04, including my ports forwarded and a test Minecraft server up... I realized that nobody could join my public IP I sent out, not even me! I can connect to the ipv4 address. It acts like I didn't forward my ports. But I forwarded 25565 to Input and Output and they're both TCP and UDP. Is this just a virtual box issue or am I doing something wrong? * Using Eth0 wired connection

• When/how to use Node with PHP or Ruby [closed]

  - by mbuurman

  For fun, I am creating a sort of microblogging webapp where people can comment on certain things. The basic "What is your opinion on this?" should be easy doable with just PHP (input the data in the database). Along with that I want to create a statistics page, also easy doable with PHP. But what if I want to update that page in realtime? How would I integrate Node on that page? Or shouldn't I use Node for that? When would you use Node?

• Ideas to automate customer order processing? [on hold]

  - by user2753657

  i am looking for a way to automate the order processing in my webshop. Normally, a user buys a product in my webshop, then, i receive an order confirmation email with order details, address etc. After receiving the order email, I login to my suppliers website and input the order details manually. My supplier then ships the item to the address specified by me. I am looking for ideas how to automate this process, especially in the case if i receive for example 4-5 order emails at one time (and not one by one with several hours between)... I was looking at the program Winautomation, but i am not sure if this fits my needs. Any ideas are appreciated. thanks!

• What do you use to create sprite graphics? [closed]

  - by SimpleRookie

  Possible Duplicate: What tools do you use for 2D art/sprite creation? What do you folks suggest for creating sprite graphics and sprite sheets? I fiddle with pixelformer and tilestudio. Pixelfromer has a kicken interface, it is quick and easy to make graphics, but a bit cumbersom if you want to make a spritemap. Tile Studio is a interesting mix or tiles and maps, but it is a bit buggy and basic. The Adobe series, just don't really seem to handle tiny graphics well. (there is a previous posting of this question existing, but it is a year old and I was hoping for further/updated input from the community)

• Getting Started with 12.04 LTS Problems

  - by mark

  Okay previously I used ubuntu 10.04 in Desktops and Loved it! I bought a newer Toshiba Satellite with an i7 CPU, 8GB Ram, 1TB HD, first thing I tried to do was install Ubuntu 9 on it then I found out it was no longer Supported. (I gave my 10.04 disk away) So I tried installing Windows 7 and experienced SO MANY problems, I am going back to try 12.04. Starting all over again. After installing 12.04 Wireless was Detected yet said it was Disabled by a Hardware Switch. Went read through the Message Boards found Solution which was Sudo rf Kill All. Okay all excited I would finally get my Ubuntu to finally work I rushed back to my laptop from the internet cafe, and went looking for the TERMINAL input on my Ubuntu 12.04, and I cannot find the Terminal. If I can't find the TERMINAL how Can I enter any Sudo Stuff? So I guess the first question is Where is the Terminal Located in 12.04? Thank you.

• Business Analyst vs. Architect [closed]

  - by suslik

  I'm a developer of a few years in the financial industry and will soon need to decide what career path to try and row towards. Broadly speaking I have two options: something more 'people' oriented like BAs, or keep coding and try to make more technical decisions like the Architects do where I currently work. Here are my perceptions right now: Business Analysts: get paid way more than devs once they do their job, it seems like they usually have no worries more likely to go REALLY high up in the organization (VPs, etc) Architects: things like certification matters (I see this as a con) called in when things go wrong more than anyone else (weekends & overtime) long career path to get to (dev - senior dev - team lead - architect) I would find the latter more intellectually rewarding, but when I look at it I just can't justify it in terms of lifestyle. Am I wrong / what am I missing? Can you really make a lot of money in a technical role or must you really get out of coding? Thank you for any constructive input.

• Custom widgets/controls in application indicators

  - by markitusss

  I want to develop an app for ubuntu, that integrates inside the calendar indicator/menu. It should allow to enter info right from it, and have several controls like input boxes, drop downs, spinners and buttons. Is this possible to integrate/replace the standard date/time indicator? If not, is it possible to create it as a separate indicator that when clicked opens a popup with all the controls and stuff? I want it to look as part of the sys tray and not as a separate desktop app. I'm using Quickly for this. Thanks for your help!

• Why CoffeeScript is an issue

  - by Renso

  Other than some obvious concerns, my main concern is support in the open source community. "anon" from the CoffeeScript team sent this to me after I requested input from the team to concerns I raised and wanted to get others' take on it:"Thanks for confirming that only idiots willingly program in Java and C#"or the following from the same person:"Oh and finally, you should definitely create jShort. Even though I know you will fail before you even start, I would love to laugh at your attempts and it would be perfect for you since you ride the short bus. "This kind of comment reflects badly on the CoffeeScript team and hence not an option for us as a company to consider. Another example of why some open-source community projects get no traction.

• Encouraging business and team members to write more code

  - by Aliixx

  I am really interested to hear any ideas or working practices that can be adopted to encourage our team of developers to write more code. A little background here is involves a team of varying disciplines, experience and qualities and the nature of the work has a large focus on bug fixes and business logic / data validation over writing lots of new greenfield code or even refactoring. We are attempting to move to a more Agile philosophy and really what would be great is to hear any ideas that can be sold to the team and / or the business with the aim of: Writing more new code to improve experience, abilities and increase exposure to newer and emerging patterns and practices. Energizing the effort of the team and inspire. Encouraging wider input of new ideas, patterns and practices from the team as a whole. I would be very interested (and grateful) to hear any ideas or examples of ideas that can help here. Thanks!

• << and >> in C++

  - by JacKeown

  I don't quite understand what this means...I'm just learning C++ from my very very very basic Python experience...and so this may be a very stupid question. My question is...say you have your classic "Hello World" program and you have the line: cout<<"Hello World!"<<endl; what does the << mean...because I was just looking at using input in C and saw that you'd do something like: int i; cini; and I noticed that it has instead of << and I've read that those are bitwise shifts...and I don't exactly understand what those are...but I think it might be different here...Help...Thanks in advance

• How to run CLI commands from the launcher?

  - by user50849

  I press ALT+F2 key on my keyboard, and get the launcher HUD up. From there I enter a command as I would in a shell, specifically vlc ~/Music/* -Z. If done from a shell, vlc starts and begins to play music. However, when done from the launcher, VLC replies: File reading failed: VLC could not open the file "/home/[username]/Music/*". (No such file or directory) user Your input can't be opened: VLC is unable to open the MRL 'file:///home/[username]/Music/%2A'. Check the log for details. I can't quite figure out what the difference is.

• How to install ubuntu from desktop w/o internet access?

  - by Tom P.

  I am trying to install ubuntu on a netbook without a CD drive. I first attempted a flash drive, but it did not work, so I decided to use the flash drive to transfer the application that can install from the desktop. However, this is a secondhand school computer that needs its borderline spyware security suite wiped before it can access the internet, so I cannot use the install from desktop application. Do I have any other options? I do have access to an external CD drive that I could try, but I am unconvinced that I would get different results since it would have to go through a USB port. Any and all input is very much appreciated!

• XNA + Windows Forms: How make them work together without making the trick of the custom GraphicsDeviceControl?

  - by Renann

  What I've found is a solution where you have to code a custom GraphicsDeviceControl to put inside the form (the well known tutorial from the APPHub), but that's not what I'm searching for. I would like to say that before start to right my question here, I "googled" a lot and I saw some questions here, but I couldn't find what I'm looking for. I would like to have the Draw/Update loops completly managed by XNAFrameWork (with XNA project and so), and not by a custom component. I hope you understand what I asked. Thanks in advance. Edit What's the most important thing for me and wasn't shown in the tutorial of APPHub is: where I have to put the input handling? That's one the problems that wasn't covered by the tutorial.

• Single Full Name field in registration form user submits only first what to enter in my backend as last?

  - by Anagio

  On a registration form I have a single input called Full Name. The strings are parsed with http://code.google.com/p/php-name-parser/ so if a person enters their full name middle or any quantity of strings it's handled just fine and the app creates the user in a billing system with it's API. The form validates and checks for two strings in the field otherwise it won't post. I'd like to remove this validation but a last name is required by the API. You cannot post an empty last name to the API. Users are signing up for a trial so I don't want them having to deal with many form fields. The only place the last name shows up visible to the user is in their account settings page. If they end their trial and start a paid plan they'd have to enter their billing details which asks with two fields for their First, Last, and other billing information. What is an alternative to submitting "Doe", "Default", "Empty" in place of them not filling in their last name?

  i use AuroraMint as my themes. but some colors mess up my opera. when i use "gnome-appearance-properties-customize theme-Colors", i only can found input boxes' text color here. but i still want change background colors in email list (opera use GTK theme here). Gui give only 4 group colors here, so poor.
