• What are the differences between GIT and SVN when it comes to merge conflicts solving.

  - by chalup

  I keep hearing that branching in git is so much easier than in SVN, because it's easier to merge the branch back to trunk/master. I've read some tutorials, but they only covered basic merge conflicts ("Alice changed line 8 of code.cpp and at the same time Bob changed line 8 of code.cpp...") and there are no differences between SVN and all other distributed source control systems. Can you give me the examples of changes in branch that would cause troubles in SVN repository, but would be handled gracefully by git?

• HTML Comment-out Add-In

  - by Velika

  Here is an old add in to quickly comment out HTML code. Maybe I am missing it, but it seems like there is a shortcut in VS2010 to scratch your tail with one click but commenting out HTML code is still awkward as hell. What's the easiest way to get a function like this working? Can I expect any add-ins that were written for older versions of VS to work in VS2010 w/o an upgrade?

• Monotouch stringWithFormat using a URL

  - by Pselus

  I'm trying to learn the MapKit with Monotouch and I'm having difficulty figuring out how to search for an address. I finally found this snippet of Objective-C code that might help but it has a line where they use a URL to get a return value and I have no idea how to use this code in C#: NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", [addressField.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; If anyone could give me some advice that would be helpful.

  - by Thomas O

  Python says I need 4 bytes for a format code of "BH": struct.error: unpack requires a string argument of length 4 Here is the code, I am putting in 3 bytes as I think is needed: major, minor = struct.unpack("BH", self.fp.read(3)) "B" = Unsigned char (1 byte) + "H" unsigned short (2 bytes) = 3 bytes (!?) struct.calcsize("BH") says 4 bytes.

• json KeyError with json.loads

  - by user322775

  my apologies in advance for a python and json nubie question. json seems to be hiccuping on the following statements: {"delete":{"status":{"id":12600579001,"user_id":55389449}}} code snippet: temp = json.loads(line) text = temp['text'] I get the following error output when the above code snippet encounters lines similar to the above json 'dictionary': text = temp['text'] KeyError: 'text' Is it because there is no "text" key in the line or because "delete" is not in the dictionary?

• Recycle a project name?

  - by deamon

  I want to start an open source project, but my favourite project name was already used for a framework with the same goal. This project was never popular, had only two active days with commits at Google Code and is dead since four years. In other words: the project is irrelevant but the name is in use at Google Code and ohloh (the same dead project). The .org domain would be available. Would it be ok to reuse this project name?

• Online PHP/HTML/JS/CSS editor

  - by pistacchio

  Hi to all, is there any free php code that, once installed, allows you to browse and edit files (with html, javascript, php and css highlight) on the server where it's installed? The aim is to code online, browser based. I've tried http://phpanywhere.net/ that can make this possible, but it is buggy and moreover it requires an external (ftp) access to your server that is quite different (and less secure) that working directly on the server. Thanks in advance

• How to store an ItemsSource for an ItemsControl (ListBox, ComboBox) in the app.config?

  - by Dabblernl

  After much research and trial and error I found how to store the items for a ListBox and ComboBox in the app.Config. I am heavily indebted to Jon Rista, who wrote a series of articles about the Net 2.0 Configuration classes. I constructed a (large!) code snippet that will generate all the code you need by just inserting three strings! Enjoy!

• Is TcpClient BeginRead/Send thread safe?

  - by wb

  Using a dotNET TcpClient if I have called an asynchronous BeginRead() on the associated network stream can I still call Write() on that stream on another thread? Or do I have to lock() the TcpClient in the code that is called back from the BeginRead and the code that does the send? Also if I close the TcpClient with: client.GetStream().Close(); client.Close(); Do I have to lock() on the TcpClient as well? Thanks in advance.
