• Using Powershell to set user permissions in Reporting Services

  - by slugster

  I'm asking this because i'm a n00b when it comes to Powershell. How do i use Powershell to add a particular domain user or group to a specific reporting role in SSRS2005 (say the Content Manager or Browser role)? Is there a simple one or two line script to achieve it? Thanks! Note: this is definately programming related (not server admin), but i am also going to ask this on SF.

• Trap error or 'Resume Next'

  - by Craig Johnston

  I realise this is an older programming environment, but I have to clean up some VB6 code and I am finding that most of it uses: Resume Next What is the general consensus about the use of Resume Next? Surely, if there is an error, you would want the app to stop what it was doing, rollback any data changes, and inform the user of the error, rather than just resuming. When is it good idea to use Resume?

• Are open source projects considered community service?

  - by Gio Borje

  I'm currently a junior in high school and I've been slacking off on my community service to develop websites and do some personal projects in C#. Currently, I'm developing an web-based IM-Chat through node.js (the server-side Javascript). If I were to post this or other projects on Github or on Google Code, could this be considered community service?—to the programming community?

• Removing the transparency from image while keeping the actual image

  - by KPL

  Hello people, I have three images,and , they are not square or rectangular in shape. They are just like face of anyone. So, basically, my images are in the size 196x196 or anything like that, but complete square or rectangle with the face in the middle and transperant background in the rest of the portion. Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question.

• realloc()ing memory for a buffer used in recv()

  - by Hristo

  I need to recv() data from a socket and store it into a buffer, but I need to make sure get all of the data so I have things in a loop. So to makes sure I don't run out of room in my buffer, I'm trying to use realloc to resize the memory allocated to the buffer. So far I have: // receive response int i = 0; int amntRecvd = 0; char *pageContentBuffer = (char*) malloc(4096 * sizeof(char)); while ((amntRecvd = recv(proxySocketFD, pageContentBuffer + i, 4096, 0)) > 0) { i += amntRecvd; realloc(pageContentBuffer, 4096 + sizeof(pageContentBuffer)); } However, this doesn't seem to be working properly since Valgrind is complaining "valgrind: the 'impossible' happened:". Any advice as to how this should be done properly? Thanks, Hristo

• Computer graphics research

  - by Shrey

  What are the best known labs for research in CG especially raytracing/rendering? I want to pursue Masters/PhD in this field and though I have been working on projects such as raytracers, it is all self-driven. What would be a good place to start, perhaps as a research intern? Also, what kind of background is expected for admissions in these programs, in terms of programming skills, formal education etc.?

• Simulate Incorrect Content-Length Headers for HTTP in C#

  - by cfeduke

  We are building a comprehensive integration test framework in C# for our application which exists on top of HTTP using IIS7 to host our applications. As part of our integration tests we want to test incoming requests which will result in EndOfStreamExceptions ("Unable to read beyond end of stream") that occur when a client sends up a HTTP header indicating a larger body size than it actually transmits as part of the body. We want to test our error recovery code for this condition so we need to simulate these sorts of requests. I am looking for a .NET Fx-based socket library or custom HttpWebRequest replacement that specifically allows developers to simulate such conditions to add to our integration test suite. Does anyone know of any such libraries? A scriptable solution would work as well.

• Object Oriented Database - why most of the companies do not use them

  - by GigaPr

  Hi, I am pretty new to programming(just finished University). I have been thought in the last 4 years about Object Oriented development and the numerous advantages of this approach. My question is Isn't it easier to use a pure Object Oriented database in development applications? Why Object Oriented database are not as much diffuse as relational? From my point of view makes sense to use OO database, the latter will avoid the numerous construction necessary for the mapping of complex objects on the tables.

• Implementing dynamic scope when using CPS as intermediate language

  - by asandroq

  I am currently studying the implementation of programming languages and became interested in using Continuation-Passing Style as the intermediate language of the compiler. I also want to implement limited dynamic scope (for exception-handling or Scheme parameter objects) but I cannot find the relevant literature. I think it can be done with a separate environment passed as a variable to every closure, but this solution seems ugly to me. Could anyone point me to the relevant literature, or give me an idea of how this can be done?

• Anyone up to creating a tomcat based alternative for GAE?

  - by bach

  Hi, If we had the possibility to run GAE app without any code change on our servlet engine that would be great because: in case that google changes their billing policy we can just jump to our own server or in case their current policy doesn't fit our app needs we can do stuff which is not allowed in the GAE, compromising a 1 JVM, 1 DB We don't actually need a distributed system but more of a realtime system with synchronize, true locking mechanisms, other servers/software installed on the server machine, socket interface etc... Such a package should include at least: TomCat (or equivalent) DataNucleus Access Platform (Task Queue service) Any idea if it's easy to get such a thing or if it's already exist somewhere? Thanks

• Most valuable course in the CS degree.

  - by danielrutledge

  I was a math major and I took OOP and Algorithms & Data Structures from the CS department while in school, but didn't continue to any upper-division courses. What were the most valuable courses to your programming career (Operating systems, Compiler Design, Computer architecture, etc) in your CS degree? Alternatively, if you're like me and don't have one, are there any courses you wish you had taken? What would be the best way to fill in the gaps in my knowledge outside of school?

• Advice and resources for Apple iOS 4 development

  - by mlambie

  I'm looking for resources, screencasts, books, courses, sites and the like to assist with learning Objective-C with the intention of developing applications for Apple's iOS 4. My development team has access to Apple's development program, and is largely coming from a similar background: they're Comp Sci graduates that have experience with Ruby and web languages, but haven't written any C since university. Considering Apple's announcement regarding limited programming language support for developers, what's the current best avenue for learning Objective-C with the desire for developing iPad and iPhone applications?

• Basis for claim that the number of bugs per line of code is constant regardless of the language used

  - by Matt R

  I've heard people say (although I can't recall who in particular) that the number of bugs per line of code is roughly constant regardless of what language is used. What is the research that backs this up? Edited to add: I don't have access to it, but apparently the authors of this paper "asked the question whether the number of bugs per lines of code (LOC) is the same for programs written in different programming languages or not."

• Java library to encode / decode AMF

  - by Ceilingfish

  Hi chaps, I currently have a Java server that talks to a Flash client by passing JSON encoded data over a binary socket connection. Is there a way on either side to encode / decode packets as AMF instead of JSON? It seems to me that there should be some native support in Flash player for doing this? All the implementations I have found of AMF serialization seem to be embedded inside an application framework. Simiarly so, does anyone know if it's possible to decode AMF packets independently of a connection implementation in Flash?
