• Data structures for a 3D array

  - by Smallbro

  Currently I've been using a 3D array for my tiles in a 2D world but the 3D side comes in when moving down into caves and whatnot. Now this is not memory efficient and I switched over to a 2D array and can now have much larger maps. The only issue I'm having now is that it seems that my tiles cannot occupy the same space as a tile on the same z level. My current structure means that each block has its own z variable. This is what it used to look like: map.blockData[x][y][z] = new Block(); however now it works like this map.blockData[x][y] = new Block(z); I'm not sure why but if I decide to use the same space on say the floor below it wont allow me to. Does anyone have any ideas on how I can add a z-axis to my 2D array? I'm using java but I reckon the concept carries across different languages.

• Hosting a Small PHP/MySQL Project [closed]

  - by paulrehkugler

  I have a small PHP/MySQL project in the works and I'm looking for somewhere to host it. My criteria are: Ability to run PHP/MySQL (either natively, or contains the ability to install). Ability to manipulate the web server, so I can make pretty URLs. Not spammy (if you've ever looked for hosting, you know what I mean). Semi-professional - no ridiculous downtime or long response time. I obviously don't need anything spectacular (I'm not aiming to be the next Facebook) but something that doesn't seem cheap. Reasonably priced - obviously this is a side project for fun so I'm not planning on making or dispensing any sort of "serious" revenue.

• Plugins in Ops Center and Cloud Control

  - by Owen Allen

  Cloud Control just released an updated plugin for Oracle Virtual Networking, so I thought I'd mention a bit about how both Ops Center and Cloud Control use plugins. On the Ops Center side, we have a plugin to connect Ops Center to Cloud Control, letting them share monitoring data. This guide explains how to install and use that plugin. In Cloud Control, they have a more extensive collection of plugins, letting you link Cloud Control with a variety of other products. The Cloud Control library plug-in tab goes into more detail about how you can use these plugins in your environment.

• Animate sprite/texture position with VBO

  - by Dono

  I'm currently worlking on a renderer for my projects and I want animate a sprite on screen. I've got a spritesheet but I don't know what is the the best way to update the texture coordinates for each vertex. Update vertices then update vertex buffer. (Heavy ?) Send to the shader my texture coordinates (It is possible ?) Don't use VBO ? By the way, I've got this structure : Object class with Geometry (Faces + Vertex + Buffer) and Material (Shader + other stuff ) properties, it is a good structure ? Thanks!

• Presenting to the New England SQL Server Users Group 10 Jun 2010!

  - by andyleonard

  I am honored to present Applied SSIS Design Patterns to the New England SQL Server Users Group on 10 Jun 2010! This is a reprise of the spotlight session presented at the PASS Summit 2009. Abstract "Design Patterns" is more than a trendy buzz phrase; design patterns are a way of breaking down complex development projects into manageable tasks. They lend themselves to several development methodologies and apply to SSIS development. Chances are you're using your own design patterns now! In this spotlight...(read more)

• Combining a content management system with ASP.NET

  - by Ek0nomik

  I am going to be creating a site that seems like it requires a blend of a content management system (CMS) and some custom web development (which is done in ASP.NET MVC). I have plenty of web development experience to understand the ASP.NET MVC side of the fence, but, I don't have a lot of CMS knowledge aside from getting one stood up. Right now my biggest question is around integrating security from ASP.NET with the CMS. I currently have an ASP.NET MVC site that handles the authentication for multiple production sites and creates an authentication cookie under our domain (*.example.com). The page acts like a single sign on page since the cookie is a wildcard and can be used in any other applications of the same domain. I'd really like to avoid having users put in their credentials twice. Is there a CMS that will play well with the ASP.NET Forms Authentication given how I have these existing applications structured? As an aside, right now I am leaning towards Drupal, but, that isn't finalized.

• Alternative Web model

  - by Above The Gods

  One of the problems web apps have against native apps, especially on the mobile front, is the constant need to re-download each web page on request. Ultimately, this leads to slower performance. Why if web apps only download new pages if they're actually needed, not because they're simply requested. For example: perhaps the server can store a web page version in a cookie. Every slight change to the page on the server-side changes the version number. Now instead of the browser requesting a new page each time, why not just check the version number and have the server send the page if they're different? If the page similar, the user can just use a cached page. I'm sure browsers doesn't necessarily have to change to accommodate changes to this, correct?

• IIS to parse php in a .dll files

  - by Agony

  The .dll files ain't the dynamic link library. That's what the client side software calls for (cannot change). Its essentially a php script that should run and return specific values. However currently it simply downloads it and that results in a failure. That's what it results in on a Apache server: [Update] NewVersion=1 UpdateFileNumber=1 UpdateFile1=update1/LPServerInfo.dat ServerNumber=1 Server1=http://88.159.116.217/ here it is on IIS: 198.24.133.74:8080/update.dll?0 renaming it to php works fine for testing - it runs and returns values. I edited the MIME and set .dll to application/x-httpd-php but that doesn't seem to work in IIS. Any solutions?

• What are some ways people deploy relational database changes using Node.js? [closed]

  - by JamesEggers

  I've been diving more and more into Node.js and hosting services like Heroku and Nodejitsu recently and have been trying to figure out how to best deploy database changes for postgres or mysql. There are a few migration projects under npm that I can see; however, all seem to be really buggy or just not work. I currently manage the Monarch migration project on npm, but it's currently buggy itself and my experiences developing such utilities are in other, more procedural, languages. So what do people use to deploy changes to their databases on these environments? What has worked for people? I'm looking for a better understanding of what the current situation/process looks like.

• Django - need to split a table across multiple locations [closed]

  - by MikeRand

  Hi all, I have a Django project to track our company's restructuring projects. Here's the very simple model: class Project(models.Model): code = models.CharField(max_length=30) description = models.CharField(max_length=60) class Employee(models.Model): project = models.ForeignKey(Project) employee_id = models.IntegerField() country_code = models.CharField(max_length=3) severance = models.IntegerField() Due to regulations in some European countries, I'm not allowed to keep employee-level severance information in a database that sits on a box outside of that country. In Django, how do I manage the need to have my Employee table split across multiple databases based on an Employee attribute (i.e. country_code) in a way that doesn't impact anything else in the project (e.g. views, templates, admin)? Thanks, Mike

• Can all code be represented as a series of Map / Filter / Reduce operations?

  - by Mongus Pong

  I have recently been refactoring large chunks of code and replacing them with Linq queries. Removing the language bias - Linq is essentially a set of Map / Filter and Reduce operations that operate on a sequence of data. This got me thinking, how far would I theoretically be able to take this. Would I be able to rewrite the whole code base into a series (or even a single) of Map / Filter and Reduce operations. Unfortunately I get paid to do useful stuff, so I haven't been able to experiment much further, but I can't think of any code structure that couldn't be re structured as such. Side effected code can be dealt with via monads.. Even output is essentially mapping memory addresses to screen addresses. Is there anything that couldn't be (theoretically) rewritten as a Linq query?

• Netbeans 7.0.1 not opening

  I am working in Netbeans on Ubuntu for the last 4 months. But today when I opened Netbeans, it just got stuck in the Ubuntu launcher bar at the left side of screen. I have my project pending in Netbeans (which is not opening). I am stuck in this problem. I also rebooted Ubuntu a number of times, still the same. I can't open Netbeans. Why is this happening? What is the cause of this problem? What should I do? tried $gksu netbeans, nothing happens, $ prompt shown again.

• How do I get started with HTML5? [closed]

  - by daniel.sedlacek

  What is the recommended workflow to learn HTML5? What tools should I install? What SDK? Where to start? How to test? How to debug? What do I read? I understand that what is often labelled as "HTML5 development" is in fact a mixture of HTML, CSS, JS and more, however I don't believe that bigger projects are developed in Notepad. That is why I am asking you to reveal your tips and tricks about your workflow.

• GPL question : web application using Imagick and GhostScript => Which would be the final licence?

  - by sdespont

  I am a bit confusing and I need your help to undertand my problem. I have developed a web application (PHP, JQuery) for one of my customer. Recently, my customer ask me to add a new feature permitting PDF to JPG conversion. After web browsing, I have discovered that iMagick (Apache licence) PHP extension with GhostScript (GPL licence) is the only solution. But, as my customer want to sell the web application to others companies, I have to use non-GPL licences. By the way, this feature is OPTIONAL and the final user must download and install manually iMagick and GhostScript if he his interesting by using the PDF conversion. Is there someone to tell me if the fact to use Imagick to convert PDF to JPG (and therefore use GhostScript) turns my current proprietary licence to GPL? And what about if I don't use Imagick but call GhostScript using PHP exec() function? Is there others non-GPL projects to convert PDF to JPG that I could use with PHP? Any help would be greatly appreciated.

• Server costs and back loading for mobile devices

  - by user23844

  A company approached me to design an MMO for the mobile platform and I have the perfect idea for them. My question is how much would a server for a FTP game that has both a PVE element and PVP cost? Also do you think that it would be better or is it even possible to back load the data onto the phones (trying to come up with some interesting way to back up the data in case of emergency). I don't want the game to be totally online reliant (I want to appeal to not only phone users but also iPod touch users) and for there to be an offline mode. If you can't tell this is my first game besides simple projects I've done on the side. Any help would be greatly appreciated.

• Reduced Tree View in NetBeans IDE 7.2

  - by Geertjan

  Right-click within the Projects window in NetBeans IDE 7.2 and from the "View Java Packages As" menu, you can now choose "Reduced Tree".I never really understood the difference between "Reduced Tree" and the already existing "Tree". But it makes sense when you see it. Here's Reduced Tree view: And here's Tree view, where you can see that the "actions" and "nodes" packages above each have their own top level package nodes, which takes up more space than the above: What's cool is that your selected package view is persisted across restarts of the IDE. To be complete, here's the List view, which is the third option you have in the "View Java Packages As" menu: Seems to me like the new Reduced Tree view combines the best of the Tree view with the best of the List view! Related issue: http://netbeans.org/bugzilla/show_bug.cgi?id=53192

• What's the best route to getting started in moble app development?

  - by Rob Z

  As per the question title, I'm interested in starting up a new side project and I'm currently looking at doing a bit of mobile development as said project. I'm actually in a bit of a good position right now as I have a blank slate in front of me (i.e. not locked into a phone already) but on the same token, I also don't want to invest too much money into hardware and the like since this will likely not be a money making venture. As such, which platform provides the best flexibility in terms of experimentation and learning opportunities? Likewise, what are some useful resources to assist in the process?

• What do you miss when you have to use C instead of C++?

  - by sharkin

  This is not a question about which of the two languages is better than the other. I myself can't really decide. Pros and cons as always I guess. Also, if you feel you always would prefer C over C++, this poll is not for you :-). However, when I work in C projects I usually feel I'm missing a few language constructs more than others, which can be found in C++. For example, I usually miss (the obvious) classes, but seldomly templates (I always miss STL, but wouldn't call it a language construct). What do you miss when you have to use C instead of C++?

• Tell the kernel to strongly cache a particular directory

  - by silviot

  This question is a rephrasing of Optimizing EXT4 performance. I have a directory that contains build files, most very small, but totaling 5.6G. I usually access the same subset of files (some thousands, for some tens of megabytes) over and over again. The subset changes daily (different projects, different versions of libraries). What takes longer when I use it seem to be disk seeks. For example if I do a du twice the second time it takes as much time as the first, and disk activity is similar. Ideally I'd like to tell the kernel to allocate X Mb to the metadata and Y to data in the folder, like the options for nfs cache. Is it possible in some way, other than mounting nfs from localhost and caching it to a ramdisk?

• Can Agile/Scrum be used by 1 or 2 developers?

  - by Dillie-O

  Everything I've been reading and researching up to this point describes how Agile/Scrum works great with teams of about 4 to 6 members, maybe even more. In my current shop, we have about 8 developers or so, but given the nature of the volume of projects and the number of departments we support, we never have more than 1 or 2 folks assigned to a given project. Can I still use Agile/Scrum with a team of 1 or 2 developers? I'm working on making the pitch to my manager to start working with this methodology, but I need to be able to explain how to scale things back for a small developer crew, or convince them to make sure we get more members on a given project.
