• Would a professional, self taught programmer benefit from reading an algorithms book?

  - by user65483

  I'm a 100% self taught, professional programmer (I've worked at a few web startups and made a few independent games). I've read quite a few of the "essential" books (Clean Code, The Pragmatic Programmer, Code Complete, SICP, K&R). I'm considering reading Introduction to Algorithms. I've asked a few colleagues if reading it will improve my programming skills, and I got very mixed answers. A few said yes, a few said no, and a one said "only if you spend a lot of time implementing these algorithms" (I don't). So, I figured I'd ask Stack Exchange. Is it worth the time to read about algorithms if you're a professional programmer who seldom needs to use complex algorithms? For what it's worth, I have a strong mathematical background (have a 2 year degree in Mathematics; took Linear Algebra, Differential Equations, Calc I-III).

• OOW 2012 Tuesday: Hands-On Introduction to Integration and Oracle SOA Suite 11g

  - by Simone Geib

  This year's SOA Suite hands on lab offers three different options, dependant on your level of expertise and interest. If you're new to SOA Suite, you should pick option 1 and learn how to build a SOA composite from the ground up, including a BPEL process, adapters, business rules and human task. The end result will be a purchase order process to be deployed through JDeveloper and tested in Enterprise Manager Fusion Middleware Control. If you're already experienced in SOA Suite, lab option 2 walks you through setting up the components that will allow you to utilize continuous integration with your SOA Suite 11g development projects. For those who want to learn more about security in the context of SOA Suite, option 3 shows you how to secure WebLogic services and SOA composites using Oracle Web Services Manager (OWSM). Hope to see you there! Session ID: HOL9989Session Title: Hands-On Introduction to Integration and Oracle SOA Suite 11gVenue / Room: Marriott Marquis - Salon 3/4Date and Time: 10/2/12, 11:45 - 12:45

• Creating your First Crystal Report for Use in a .NET Application

  Have you ever had to create a custom report within an application you have written for a customer? Most developers have, and there are two schools of thought on how developers normally perform this task. Some choose to create the report using the same technology that the application was created in (ASP, WinFrom, WPF) while others choose to use a reporting package such as Crystal Reports. Using a reporting package will help create reports rapidly. This article walk you through the creation of your first report using Crystal Reports.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.

• Forking project on Github process

  - by Mike Wills

  There is a project on Github that I mostly like and want to use. There are a few things I want to do differently/remove that doesn't make sense for what I want/need. Also I want to add a few things as well. As I understand it, I should fork the project and I can make whatever changes I want and push back to my fork. From there, I also want to occasionally pull into my fork the changes from the original project so I get the latest bug fixes/features. Am I off-base of how I think it should work? How would bring in the changes from the original project?

• OpenGL ES 2.0 example for JOGL

  - by fjdutoit

  I've scoured the internet for the last few hours looking for an example of how to run even the most basic OpenGL ES 2 example using JOGL but "by Jupiter!" it has been a total fail. I tried converting the android example from the OpenGL ES 2.0 Programming Guide examples (and at the same time looking at the WebGL example -- which worked fine) yet without any success. Are there any examples out there? If anyone else wants some extra help regarding this question see this thread on the official Jogamp forum.

• Didn't do too well on a Java IKM test, advice?

  - by Jason

  I did an IKM Java test recently and got quite a low score. I only graduated a year ago and I dont have commercial experience in Java (i do web development in my current job). I thought reading up a lot on Java would help me prepare, but when I sat the IKM test i got ripped to pieces. I didn't know much about how the garbage collection actually works, names of other java compilers (i know about javac?), using .dll with Java etc etc. I know a wide range of the basics, but to the extent wether 'int(5L)' produces an integer or not, I really didnt know. My question is that many of the IKM questions I have never come across, yet I have read many of the wider-known Java programming books (Deitel, O'Reilly etc). Am i reading the wrong books??? Could anyone recommend a good plan of action to allow me to go away and self-study and be able to know these really tough java questions?

• What are the fundamentals of game development?

  - by Matt

  Hi, I completely do not understand how a video game can be coded. I'm a beginner programmer and only have experience writing console applications that do math and what not. I do not understand how these logical processes can make images move on the screen (video games). Obviously if i jumped into a game development book or something like that I would understand but I am currently still getting a grasp of the fundamentals of programming in general. Could anyone give a simple explanation , coding wise, on the jump between making a computer do simple math to making a computer produce amazing graphical programs such as video games? Maybe there are some intro videos someone can point me to? I

• Cheerp -- C++ for web: advance or regression?

  - by Henrique Barcelos

  Recently I've run into Cheerp, a C++ to Javascript compiler, which uses a modified version of clang to generate Javascript code from C++ sources. That makes me wonder: why in the seven kingdoms would someone do this in their right mind? I mean: why would you take a language that is not designed for web at all, that is far more convoluted and bureaucratic, write your code and then compile it into Javascript itself? Can anybody see any advantages in doing so? We surely can discard performance as a reason, because in the end it generates pure Javascript code. Is there anyone here that have real experience with this? P.S.: I'm not sure if this is an on topic question, but this is the most general forum about programming that I could find in the StackExchange network. Edit Although this seems like a subjective question, it is not. I am asking for reasons that this tool could be useful. I got interested at first, but started wondering why would someone use it.

• Stuxnet aurait préalablement été testé par les militaires d'Israël, plus de deux ans avant son lancement sur l'Iran

  Stuxnet aurait préalablement été testé par les militaires d'Israël, plus de deux ans avant son lancement sur l'Iran Mise à jour du 17.01.2011 par Katleen De nouvelles informations viennent de tomber concernant Stuxnet, la bête noire de l'Iran. Le ver aurait ainsi été testé en secret dans une base militaire Israélienne (le complexe Dimona dans le désert de Negev) avant d'être lâché sur les infrastructure nucléaires iraniennes. Deux ans avant leur mise en oeuvre, les attaques auraient été simulées sur les mêmes machines que celles visées, pour garantir le succès futur de l'opération grandeur nature. En conséquence, des experts auraient examiné les failles des contrôleurs ...

• Ubuntu user credentials, file permissions

  - by user9843

  I am using Ubuntu 10.10 for web development by using the symfony framework. Normally I install Ubuntu Lamp (Turnkey edition), log in as root and configure all the necessary software in the server needed to work with symfony. (Samba, symfony etc) The problem is when I am root the file permissions are not set right for the Samba and symfony systems. All things I do/create in the terminal (CLI) of Ubuntu create file permissions for the user root. Off course I know how to change them afterwards but that takes up time I could spend programming. When ready I am using the box via my network, creating several site directorys directly from my pc on the server. There are multiple sites on this developer server as directorys under /var/www/ there are no virtual hosts. My question is how to create or set a user after installation of Ubuntu with the right credentials and rights?

• Boot-Repair after messing up NTFS partition

  - by QuietThud

  I posted this question explaining what happened after I tried to create a new swap partition on a Win/Ubuntu dual-boot machine. I have since created a live-boot USB and installed Boot-Repair. I had it "recommend repairs", after which it tried repairing the wubi filesystems, which as far as I'm aware was not necessary. I'm not sure where to go from here; I don't care very much about backing up my files, I just want to be able to boot the machine. In the Advanced Options the "Repair Windows boot files" box is uncheckable both GRUB tabs are unclickable (I do have GRUB installed) Here is my Pastebinit with the details from the Boot-Repair. Please be as explicit as possible, as I am proving to be disproportionately bad at this type of task. Thank you! P.S. I keep seeing: cryptsetup: WARNING: failed to detect canonical device of overlayfs cryptsetup: WARNING: could not determine root device from /etc/fstab TestDisk: GPARTED:

• I made a game in XNA - how can I share it with my friends?

  - by Raven Dreamer

  I've just finished programming a charming (albeit bare-bones) XNA version of arcade classic Tempest. Hooray! Given that this was a homework assignment, I'd like to be able to share it with my professor and my friends/classmates to solicit feedback. (And let's be honest - if I have a question about how to add in an additional feature, it might be nice to be able to share it with folks on this site as well.) Is there a better way of sharing an XNA game than by shuttling the visual studio - produced executable around? Some way to host it on a website would be ideal.

• Design Patterns and their most common uses for them [closed]

  - by cable729

  Possible Duplicate: What are some programming design patterns that are useful in game development? As I'm returning to game dev, I've realized that I've lost a lot of the knowledge I had before. So now I'm looking at design patterns that I can use for my next project. One design pattern that I've seen a lot is the 'composition method,' which uses actors and components. Is that the right name for it? I'd like to look more at this and see what the advantages/pitfalls are. So what design patterns are out there, and what are the advantages/disadvantages to them?

• Chambers In A Castle Algorithm

  - by 7Aces

  Problem Statement - Given a NxM grid of 1s & 0s (1s mark walls, while 0s indicate empty chambers), the task is to identify the number of chambers & the size of the largest. And just to whet my curiosity, to find in which chamber, a cell belongs. It seems like an ad hoc problem, since the regular algorithms just don't fit in. I just can't get the logic for writing an algorithm for the problem. If you get it, pseudo-code would be of great help! Note - I have tried the regular grid search algorithms, but they don't suffice the problem requirements. Source - INOI Q Paper 2003

• College for Game Development [closed]

  - by Cole Adams

  I am currently a Freshman Computer Science Major at Samford University, but I am realizing that the actual field I want to get into is Game Development. I go to all of these classes that are supposed to make you well rounded that have nothing to do with what I want to do and frankly, after 18 years of schooling, I am sick of having to be in classes like that. I want to go to a Game Design/Development school where that is the priority and I am not overburdened with useless classes. At this point I am so tired of the Samford classes already that I am heavily considering taking next semester off and just getting a job and focusing on learning programming on my own or something like that. My question is what would be some good schools to apply to for enrollment in 2013 and what does it take to get into these schools? Thanks in advanced.

• Choosing a crossplatform for mobile development

  - by Mech0z

  I am creating a enterprise project and will develop the app for WP, Android and IPhone (Maybe also tablets) I have then done some research of what solutions are out there and have narrowed my choice down to 3 platforms (Due to my requirement to work with Bluetooth) The biggest requirement other than Bluetooth is the need to create good interfaces and module programming so its easy to maintain the whole solution, other than that I would like to use C# but its not a real requirement, but if the difference between 2 platforms is very small then it might tip the scale. Mono (MonoTouch, Mono for android) PhoneGap RhoMobile From my understanding then PhoneGap is not suited for business apps and I am not entirely sure why, but it seems like a platform made for speed rather than long term developement, not sure how true this is. RhoMobile is made for enterprice and might suit my needs, but not sure if its a good platform Anyone with insight that care to share their opinion Mono is C#, seems to be very mature and I found MvvmCross which should help organize the project

• Game-a-Week 2 (The Sequel)

  - by Matt Christian

  After finishing Game-a-Week One I immediately wanted to go back and begin refactoring the code although I also wanted to work on a game demo idea I've had for quite awhile.  I tried doing both over the holiday weekend while up north (without internet!) and eventually hit a wall with an error. Today I am going to restart my refactoring and updates by starting Game-a-Week 2.  This challenge is to do the following: Refactor the old code Add a handful of new features to the demo This sounds simple enough but will be quite a challenge to finish in just around a week.  I have an idea on how I want to refactor the code, but the new features I'd like to implement will be tricky.  I'm going to try to implement: Quest giving / finishing / NPC's Quest Log Menu Inventory giving / receiving Inventory Menu This Game-a-Week is much more design oriented although will provide a good challenge for programming as well.  Wish me luck!

• Microsoft and Joyent Announce Node.js Windows Port

  With the Node.js command line tool, developers can type ?node my_app.js.' to run JavaScript programs. It gives developers a JavaScript application programming interface (API) supplies access for the network and file system as well. One instance where Node.js often comes in handy is in the creation of scalable networked programs that emphasize high concurrency and low response times. Developers who wish to use Node.js use on Windows at this time must do so running a virtual machine with Linux.

  Possible Duplicate: How to find web hosting that meets my requirements? My business partner and I are looking for a European web-hosting service (we are situated in Europe). That service needs to be, needs to have: international servers, a server for each continent at the very least. a high amount of bandwidth. highly scalable, since we are expecting to start off small, but as our user base grows so will everything else (again, no porn or phallic jokes) need to do. a moderate to supreme customer service. of course a small downtime per annum. affordable at first, fair as we grow. I think that is all. Any input is greatly appreciated. Thank you in advance.

• Ati Radeon HD 5850 + two screens with different resolutions

  How can I use these screens like I would use in Windows? When I turn off "copy" it gives me an error. I have tried community drivers and AMD drivers but both fail at this task. I use Ubuntu 12.04 with latest updates. It did not work in Ubuntu 11.10 either. I use DVI to connect my PC to my monitor and HDMi to my TV. It is a Sony Bravia, bought in 2008. I can't remember the model. Also, this same problem occurs when I connect to two Full HD monitors, both DVI. I cannot turn of the cloning of screens. How do I turn it off? Windows can do that.
