  • How to show a live Presentation from an Android phone?

    - by Pentium10
    This is not closely related to programming stuff, so I marked as community wiki. I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen. Are there any apps that does this, or this is possible by the USB cable?

  • Tuning Nvidia driver in Nvidia X Server Settings in Ubuntu to avoid tearing?

    - by c00kiemonster
    I'm running Ubuntu 10.10 on an Asus at3ion motherboard. I have installed the proprietary nvidia drivers and everything is working fine, but it's a but ragged when I move windows etc. I think the issue is called tearing. There is flickering and the window isn't refreshed smoothly. The ion acceleration works fine (I am running xbmc at 1080p completely without any issues). Please note I am not interested in any fancy effects etc, I just want the graphics to be smooth and nice. How can I tune the nvidia driver for this, i.e., what do I need to change in the Nvidia X Server Settings?

  • What is the best book for learning about Algorithms?

    - by sheats
    I know what algorithms are, but I have never consciously used or created one for any of the programming that I have done. So I'd like to get a book about the subject - I'd prefer if it was in python but that's not a strict requirement. What book about algorithms helped you most to understand, use, and create algorithms? One book per answer so they can be voted on...

  • What should students be taught first when first learning sorting algorithms?

    - by Johan
    If you were a programming teacher and you had to choose one sorting algorithm to teach your students which one would it be? I am asking for only one because I just want to introduce the concept of sorting. Should it be the bubble sort or the selection sort? I have noticed that these two are taught most often. Is there another type of sort that will explain sorting in an easier to understand way?

  • How do I prevent my swf files being hotlinked, downloaded etc.

    - by undefined
    I have swf files that are embedded in a PHP page using SWFObject. These swf files are in the same directory as my PHP files. for example www.myurl.com/index.php embeds www.myurl.com/flashfile.swf, index.php and flashfile.swf are in the same directory. However I want to prevent people from being able to type in www.myurl.com/flashfile.swf and viewing the swf. I want the browser to deny access to this file unless it has been embedded by the PHP file. Should I move my swfs to another folder and protect this folder somehow - is this with the .htaccess file? I am running Apache on a linux machine. While my main concern is for swf files I would like to protect graphics used on the site too. all help appreciated thanks

    - by smallb
    Guys I study C++ for a second year. Till now I was doing only console app but I think it's a time to start programming in Windows. There are few alternatives and Qt is one of them but I'm also drawn towards pure Windows API - for more power of course. What would you suggest?

  • Manage 2 displays remotely

    - by neurino
    I have a pc with a nVidia Quadro graphic card. The card has 2 DisplayPort outs where 2 40" Full HD TV are connected. I need to run 2 separate fullscreen videos, one each display. The problem is displays are far from the pc station and I cannot control them from there. I tried with a remote desktop connection but when I connect screen 1 shows login and screen 2 simply blackens (I'm logged off). The pc, an HP, also has his native graphics card still installed it would be nice if I could connect there a 15" monitor with the desktop on and use the TVs only as secondary where I can send fullscreen videos. Any clue?

  • What's the best CDN for image hosting on a high-volume web site?

    - by Mike
    Akamai is way too expensive. Photobucket is not reliable. Is there a great content delivery network that I can use just to host my images? We deploy images programmatically via FTP, so there is some programming behind the scenes. Having some sort of reporting about the reliability of the service, whether it's raw logs files or a web-based admin screen that shows http errors, would also be important. Has anyone worked with edgecast?

  • Which IDE / code editor was the first to introduce a code completion feature?

    - by Uri
    I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

  • Why so many ASP.NET programmers play with Ruby on Rails after working hours?

    - by ITmeze
    I saw that on so many blogs. Lots of the people that were dealing with ASP.NET tend to play with Ruby on Rails after working hours. And It is just a matter of last one or two years. Why is it like that? Is it because when ASP.NET MVC showed up people become more open-minded - having joy with programming again they realize that some other folks had that many years ago, and they do not want to miss what they currently have?

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • Illegal Start of Expression

    - by Kraivyne
    Hello there, I have just started to learn the very basics of Java programming. Using a book entitled "Programming Video Games for the Evil Genius". I have had an Illegal Start of Expression error that I can't for the life of me get rid of. I have checked the sample code from the book and mine is identical. The error is coming from the for(int i = difficulty; i = 0; i- - ) line. Thanks for helping a newbie out. import javax.swing.*; public class S1P4 {public static void main(String[] args) throws Exception { int difficulty; difficulty = Integer.parseInt(JOptionPane.showInputDialog("How good are you?\n"+ "1 = Great\n"+"10 = Terrible")); boolean cont = false; do { cont = false; double num1 = (int)(Math.round(Math.random()*10)); double num2; do { num2 = (int)(Math.round(Math.random()*10)); } while(num2==0.0); int sign = (int)(Math.round(Math.random()*3)); double answer; System.out.println("\n\n*****"); if(sign==0) { System.out.println(num1+" times "+num2); answer = num1*num2; } else if(sign==1) { System.out.println(num1+" divided by"+num2); answer = num1/num2; } else if(sign==1) { System.out.println(num1+" plus "+num2); answer = num1+num2; } else if(sign==1) { System.out.println(num1+" minus "+num2); answer = num1-num2; } else { System.out.println(num1+" % "+num2); answer = num1%num2; } System.out.println("*****\n"); for(int i = difficulty; i >= 0; i- - ) { System.out.println(i+"..."); Thread.sleep(500); } System.out.println("ANSWER: "+answer); String again; again = JOptionPane.showInputDialog("Play again?"); if(again.equals("yes")) cont = true; } while(cont); } }

  • Antique Software [closed]

    - by Antique
    Will software ever be considered "antique"? In other words, is a stack of punch cards worth anything? (Perhaps if they were made by someone special, or the program on them was some type of programming milestone?) What about modern software?

  • Applications of concurrent queues and stacks in .NET 4

    - by Jon Harrop
    .NET 4 includes new concurrent data structures. The Bag and Dictionary collections have obvious applications but I cannot see any use for the Queue and Stack data structures. What are people using these for? Also, I've noticed that the design based upon linked lists incurs a lot of allocation and that destroys scalability. This is surprising given that the sole purpose of these collections is multicore programming. Is this an inherent limitation or are they just badly implemented?
