• New licensing for SQL Server 2012 and #BISM #Tabular usage

  - by Marco Russo (SQLBI)

  Last week Microsoft announced a new licensing schema for SQL Server 2012. If you are interested in an extensive discussion of the new licensing scheme, Denny Cherry wrote a great blog post about that. I’d like to comment about the new BI Edition license. Teo Lachev already commented about the numbers and I agree with him. I generally like the new licensing mode of SQL 2012. It maintains a very low-entry barrier for SSRS/SSAS/SSIS (Standard Edition). It has a reasonable licensing schema for 20-50...(read more)

• Is osTicket secure/private enough

  - by Andy

  I was going to use osTicket as my 'help desk' for my website, however I just got a little bit concerned when I realised that the clients' login details to see their support tickets are only their email address and a ticket ID. I am probably going over the top with security though, which is why I wanted to get some second opinions on how secure osTicket actually is and whether I should use it with my website. I run a software company, so chances are licence keys may be included in support tickets which are obviously sensitive information and valuable - so I want to ensure that the likelihood of a support ticket being hacked is very low. If there is any plugins/additions to make osTicket more 'secure', I would appreciate it if you could point me to them. Otherwise if there are any more free, more suited, help desk softwares out there please let me know. Thanks in advance

• Programmer performance

  - by RSK

  I am a PHP programmer with 1 year of experience. As I am just starting my career, I am learning a lot of things now. I can say I am a little bit of a perfectionist. When I am assigned a problem I start off by Googling. Then, even when I find a solution, I keep trying for a better one until I find 2-3 options. Then I start learning it and choose the best performing solution. Even though I am learning a lot, this process gets me labeled as a low performer. My questions: As a novice, should I continue to use this learning process and not worry about my performance? Should I focus more on my performance and less on how the code performs?

• What is the most efficient way to blur in a shader?

  - by concernedcitizen

  I'm currently working on screen space reflections. I have perfectly reflective mirror-like surfaces working, and I now need to use a blur to make the reflection on surfaces with a low specular gloss value look more diffuse. I'm having difficulty deciding how to apply the blur, though. My first idea was to just sample a lower mip level of the screen rendertarget. However, the rendertarget uses SurfaceFormat.HalfVector4 (for HDR effects), which means XNA won't allow linear filtering. Point filtering looks horrible and really doesn't give the visual cue that I want. I've thought about using some kind of Box/Gaussian blur, but this would not be ideal. I've already thrashed the texture cache in the raymarching phase before the blur even occurs (a worst case reflection could be 32 samples per pixel), and the blur kernel to make the reflections look sufficiently diffuse would be fairly large. Does anyone have any suggestions? I know it's doable, as Photon Workshop achieved the effect in Unity.

• Easy to use cross-platform 3D engines for C++ game development?

  - by davr

  I want to try my hand at writing a 3D game. However I don't want to start at such a low level of drawing individual triangles and writing my own 3D object loader and so on. I've heard of things like Irrlicht, Crystal Space 3D, and Cafu, but I don't have any experience with any of them. I'm looking for suggestions from people who have experience with these or other engines on which ones are well written, and are easy to get started using, without having to learn a ton of 3D math theory and how GPU's work internally.

• How to make my screen brightness not change when I plug my laptop in

  - by user63985

  I do not want my laptop to change brightness when my laptop power is plugged in or unplugged. I set my brightness based on how bright my surroundings are. If I am in a dark room, I set my brightness very low and when I plug my laptop in the brightness gets set to maximum which feels like sticking my eyes in boiling lava. In System Settings ? Brightness and Lock the Dim screen to save power checkbox is unchecked. My laptop is an HP Mini 110 In case it is an acpi issue I have put my acpi-support file here http://paste.ubuntu.com/1008244/

• What is the best practice to move sprites using mouse order in Tile games?

  - by Robin-Hood

  I am trying to make my first Tile-game using XNA. I have no problem drawing the map layers using TiledLib from codeplex, but, now I want to give sprite an (order) to move to a specific position on map, by selecting the sprite (left mouse click) and then right mouse click somewhere on the map to specify the target position. I don’t know what is the best practice to move sprite this way, considering that there may be collision objects in the direct path. what is the best practice to do this? Is there any demo covering this issue? thanks. BTW: I couldn’t upload snapshot because of my low score :(

• Diff Algorithm

  - by Daniel Magliola

  I've been looking like crazy for an explanation of a diff algorithm that works and is efficient. The closest I got is this link to RFC 3284 (from several Eric Sink blog posts), which describes in perfectly understandable terms the data format in which the diff results are stored. However, it has no mention whatsoever as to how a program would reach these results while doing a diff. I'm trying to research this out of personal curiosity, because I'm sure there must be tradeoffs when implementing a diff algorithm, which are pretty clear sometimes when you look at diffs and wonder "why did the diff program chose this as a change instead of that?"... Does anyone know where I can find a description of an efficient algorithm that'd end up outputting VCDIFF? By the way, if you happen to find a description of the actual algorithm used by SourceGear's DiffMerge, that'd be even better. NOTE: longest common subsequence doesn't seem to be the algorithm used by VCDIFF, it looks like they're doing something smarter, given the data format they use. Thanks!

• Developing for iOS on Linux

  - by Jay

  I am looking for an engine or library to develop a game for iOS on Linux. High level, low level, GUI, no GUI, does not matter too much. I am really looking for anything. I'm not actually talking about deploying to iOS from Linux or anything like. I just want to do the bulk of the work on Linux, with minimal changes required to run it on iOS. Edit: YES, I do have access to a Mac, but it is limited. So I want to be able to work on the project on my regular Ubuntu box. Also, I am in the paid developer program, so I can deploy to iOS devices from the Mac.

• Implementing Domain Driven Design

  - by Steve Dunn

  Is anyone using the techniques from Domain Driven Design? I've recently read the Eric Evans book of the same name (well, most of it!) and would be interested to hear from anyone who's implemented all/some of it in a project (particularly in C#/C++) I've kept this question open ended as I'd like to see as many comments as possible, but I have a few questions in particular: 1 - Should value types be real 'value types' if the language supports it? e.g. a struct in C# 2- Is there any feature in C# that makes clearer the association between the language and the model (for instance, this is an entity, this is an aggregate etc.)

• What technologies are used for Game development now days?

  - by Monika Michael

  Whenever I ask a question about game development in an online forum I always get suggestions like learning line drawing algorithms, bit level image manipulation and video decompression etc. However looking at games like God of War 3, I find it hard to believe that these games could be developed using such low level techniques. The sheer awesomeness of such games defy any comprehensible(for me) programming methodology. Besides the gaming hardware is really a monster now days. So it stands to reason that the developers would work at a higher level of abstraction. What is the latest development methodology in the gaming industry? How is it that a team of 30-35 developers (of which most is management and marketing fluff) able to make such mind boggling games? If the question seems too general could you explain the architecture of God of War 3? Or how you would go about producing a clone? That I think should be objectively answerable.

• Which iPhone/iPod Hardware to Support for iPhone Game

  - by ashes999

  I'm coming from a background of Android. I would like to figure out what kind of iBlah device hardware I need to support for iPhone game development. From my research, it seems that I need to support both iPod and iPhone. But which versions of hardware? is 3G still used? What about 3GS? For example, the -S phones seem to have dual core instead of single-core CPUs. I also worry about performance. In Android, I had a severely low-end phone, which meant pretty much anything that ran okay there ran okay on other phones. For iPhone, how do I figure out what to support in terms of performance?

• Inspiron N7110 Ubuntu 12.04 Poor WiFi Signal

  - by Joseph Risley

  Sorry if this is a repeat, I have been Googling possible answers and have not found one yet. I find my wireless signal is never 100%. Speed is fine, it's the actual signal strength that is the issue. I thought my router was the issue, but the problem was also present at the public library today. I asked the Windows and Mac users around me about their signal strength and they had full signal while mine was medium to low according to WiFiRadar. Is this a Dell problem (Realtek), or an Ubuntu problem I can fix in the terminal?

• Acer Revo (ION platform) + Maverick + 5.1 surround over HDMI

  - by Oli

  I've had a turbulent relationship with my media centre box. Every upgrade I perform on it seems to bring a brand new set of audio issues (the opposite of my desktop where things seem to get better and better). It's a Acer Revo 3600. That's basically an low-end Intel Atom chip with a Nvidia 9400M onboard. On paper that's perfect for something like a media centre. But having just upgraded to Maverick, the sound properties box only wants to offer me stereo sound over HDMI. The exact setup goes: Revo - Onkyo AV receiver - LG TV. The Onkyo box strips off the audio (supporting 7.1 -- though we're only using 6 speakers) and feeds the video onto the TV. I'd like to get to a point where Ubuntu thinks it's doing 5.1 over HDMI, upmixing stereo to 6ch and supporting DTS/AC3 (through Boxee). I've had this working before but it's frankly been a bit of a hacktastrophe. The audio chip is recognised as Nvidia MCP79/7A HDMI in alsamixer if that helps.

• File Transfer using RDP

  - by DesigningCode

  I often use RDP to log into servers.   A couple of issues I have had is that its a pain to get files onto the server from my PC at times, and, if there is something missing from the servers windows install, I can’t simply pop the DVD into remote server in some unknown location on the internet somewhere. The other day I was curious if RDP actually had anything…since it did support shared clipboards, so I went for a look through the options and low and behold, *hidden* away….. Select Options… Go to the “Local Resources” Tab, then where it has “Local devices and resources” it sneakily has a “More…” button. Which then displays a drive selection box.  Select the drive you want …. Then on your server you will get….. Nice.  That is useful.

• What is the recommended toolchain for formatting XML DocBook?

  - by Jonathan Leffler

  I've seen Best tools for working with DocBook XML documents, but my question is slightly different. Which is the currently recommended formatting toolchain - as opposed to editing tool - for XML DocBook? In Eric Raymond's 'The Art of Unix Programming' from 2003 (an excellent book!), the suggestion is XML-FO (XML Formatting Objects), but I've since seen suggestions here that indicated that XML-FO is no longer under development (though I can no longer find that question on StackOverflow, so maybe it was erroneous). Assume I'm primarily interested in Unix/Linux (including MacOS X), but I wouldn't automatically ignore Windows-only solutions. Is Apache's FOP the best way to go? Are there any alternatives?

• Thoughts of Cloud Development/Google App Engine

  - by jiewmeng

  I use mainly PHP for web development, but recently, I started thinking about using Google App Engine. It doesn't use PHP which I am already familiar with, so there will be a steeper learning curve. Probably using Python/Django. But I think it maybe worthwhile. Some advantages I see: Focus on App/Development. No need to setup/maintain server ... no more server configs Scales automatically Pay for what you use. Free for low usage Reliable, it's Google after all Some concerns though: Does database with no joins pose a problem for those who used App Engine before? Do I have to upload to Google just to test? Will it be slow compared to testing locally? What are your thoughts and opinions? Why would you use or not use App Engine?

• What can I do to give some more love and disk space to my database on Ubuntu?

  - by Yaron Naveh

  I'm new to linux. I've deployed a db to ubuntu server on amazon and found out I'm low on disk space. did df (see below) - and found out that I'm 89% capacity on one file system, but less on others. What does this mean? Do I have a few partitions and can now utilize others besides /dev/xvda1? Also /dev/xvdb seems large, is it safe to put the db in it and only use it? If so do I need to mount it or do something special? $> df -lah Filesystem Size Used Avail Use% Mounted on /dev/xvda1 8.0G 6.7G 914M 89% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys none 0 0 0 - /sys/fs/fuse/connections none 0 0 0 - /sys/kernel/debug none 0 0 0 - /sys/kernel/security udev 3.7G 8.0K 3.7G 1% /dev devpts 0 0 0 - /dev/pts tmpfs 1.5G 164K 1.5G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.7G 0 3.7G 0% /run/shm /dev/xvdb 414G 199M 393G 1% /mnt

• Create edges in Blender

  - by Mikey

  I've worked with 3DS Max in Uni and am trying to learn Blender. My problem is I know a lot of simple techniques from 3DS max that I'm having trouble translating into Blender. So my question is: Say I have a poly in the middle of a mesh and I want to split it in two. Simply adding an edge between two edges. This would cause a two 5gons either side. It's a simple technique I use every now and then when I want to modify geometry. It's called "Edge connect" in 3DS Max. In Blender the only edge connect method I can find is to create edge loops, not helpful when aiming at low poly iPhone games. Is there an equivalent in blender?

• How to code a 4x shader/filter which emulates arcade crt display behavior?

  - by Arthur Wulf White

  I want to write a shader/filer probably in adobe Pixel Bender that will do the best job possible in emulating the fill of an oldskul monochromatic arcade CRT screen. Much like this here: http://filthypants.blogspot.com/2012/07/customizing-cgwgs-crt-pixel-shader.html Here are some attributes I know will exist in this filter: It will take in a low res image 160 x 120 and return a medium res image 640 x 480. It will add scanlines It will blur the color channels to create that color bleeding effect It will distort the shape of the image from a perfect rectangle into a rounder shape. The question is, could you please provide any other attributes that are beneficial to emulating an arcade CRT feel and links and resources on coding these effects. Thanks
