• Rails or Sinatra? which is good to start learning, for a php programmer?

  - by user187809

  I've been working far too long with php and getting bored with it. I also want to learn a new language. I've been using Ruby and like it. I've to decide between Rails and Sinatra, which one would you recommend? Is it true that Sinatra can't be used to build complex apps, and its only for simple apps?

• Computing e^(-j) in C..

  - by Erkan H

  I need to compute imaginary exponential in C. As far as I know, there is no complex number library in C. It is possible to get e^x with exp(x) of math.h, but how can I compute the value of e^(-j), where j = sqrt(-1)?

• Maven: Re-use a POM file in every project.

  - by Zombies

  My goal is pretty simple actually but since there are multiple (and seemingly complex ways to do this) I wonder what I need to do... So I have certain runtime libraries (ADF libraries in particular) that are needed to be added to every project. This parent pom file will just have JAR dependencies in it. How can I use this pom file from a child pom file?

• Using git-svn (or similar) just to help out with svn merge?

  - by inger

  Some complex subversion merges are coming up in my project: big branches that have been apart for a long time. Svn gives too many conflicts. Would it be any good to use git-svn just for the benefit of making the merge more manageable? (perhaps due to its powerful content model) Can you recommend other alternatives (eg. svk) to lessen the merge pain? Thanks in advance.

• Easy way to load test asp.net application

• Is it possible to cache an asp page on the server side?

  - by SLC

  Let's assume you have a big complex index page, that shows news articles and stuff. It's not going to change very often. Can you cache it somehow on the serverside, so requests don't force to server to dynamically generate the entire page every time someone visits it? Or does ASP.NET do this automatically? If so, how does it know if something has changed?

• Prompt message box Linux or any system from removable device

  Hi all, I have some files that in windows enable me to prompt messages when a device is plugged. In case it is lost it pops up a message that says the user to please return it to he owner. Does anybody know how can I do this in Linux? I doesnt need to be a complex thing, it can be an option in a right clic menu, or a splashcreen, or anything, just to make sure that the owner of the device may be looking for it.

• "Slice" out one element from a python dictionary

  - by BCS

  I have a dictionary: D = { "foo" : "bar", "baz" : "bip" } and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz": R = { "baz" : "bip" } what I'v got now is: R = { k : D[k] } But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option. What I'm looking for is a better (cleaner) way to do this.

  While Mahjong (the actual game, not Mahjong solitare) is fairly simple in terms of basic rules and gameplay, setting objectives for the AI to transition to aim for certain end game goals seems fairly complex. Is anyone aware of any papers, research, or other materials related to this topic?

• Purpose of PHP constructors

  - by Bharanikumar

  Hi, I am working with classes and object class structure, but not at a complex level – just classes and functions, then, in one place, instantiation. As to __construct and __destruct, please tell me very simply: what is the purpose of constructors and destructors? I know the school level theoretical explanation, but i am expecting something like in real world, as in which situations we have to use them. Provide also an example, please. Regards

• Java threads for the beginner

  - by Boba

  I've been trying to explain Java threading to a colleague who has never been exposed to multi-threaded applications, but apparently I'm not a very good teacher. Can anyone recommend a good online or offline resource that can explain threading in a simple, step-by-step manner? I know it's a complex topic, but surely there exists an article, book, or other explanation that can result in an "Aha! I get it, finally!" moment.

• Cannot enable network discovery on Windows Server 2008 R2

  - by dariom

  I'm trying to enable the Network Discovery feature on a newly installed Windows Server 2008 R2 instance. The network connection is in the Home or Work profile (it is not domain joined). These are the steps I've followed: Within the Network and Sharing Center I select Change advanced sharing settings Then I select the Turn on network discovery option for the current network profile (Home or Work) I then click Save changes If I then go back to the Advanced sharing settings screen the Turn off network discovery option is selected and the machine is not visible to others within the Network node in Windows Explorer. Things I've checked: I can ping the server and connect to it using the machine name/IP address. The Windows Firewall has exceptions for Network Discovery for both Private and Public networks. File and Printer sharing is enabled and I can transfer files to/from the server by connecting to the server using a UNC path. What am I missing here?

• Networking with Windows 7

  - by Alix Axel

  I got several computers connected to my home wireless network and I want to make use of some of the features of Windows 7 for home networks but I can't seem to get them working: How do I keep files and folders in sync between specific computers? I'm not talking about Live Sync. How can I stream to Windows Media Player from another computer? I would appreciate if someone could provide me some links / solutions that address my needs. Thanks! To anyone who thinks this question is a duplicate and wants to close it please bare in mind the following: I'm not looking for additional software, I know I can use Live Sync, Dropbox and so on but I'm asking this: how do I configure Windows 7 to sync files between my home network - no Internet required! This has something to do with shared folders and offline files in Windows 7, but I can't get it to work. PS: Please merge with this question: http://superuser.com/questions/139763/networking-with-windows-7

• Web Client Service constantly in 'Stopping' state

  - by Mark

  I have a user who's Web Client service constantly reports that it's in the 'Stopping' state and it's hindering her ability to save JMP files to a SharePoint site using the UNC path. She's running Windows XP Service Pack 3. I've tried modifying the Web Client parameters in the registry for UseBasicAuth and FileAttributesLimitInBytes with no luck. When I set the service to Manual and then try to start it after Windows boots up, it starts and then immediately goes into the Stopping state again. Other things I've tried: Removing/Reinstalling her network card Removing/Reinstalling the Client for Microsoft Networks and File and Print Sharing Checked that the BITS and RPC services are running fine (not sure if they're related) Does anyone have any other ideas? Is there a way to repair/rebuild the Web Client service?
