• How to fix error in a Mercurial changeset comment?

  - by Sly

  Is there a way to rewrite the hg commit message if the wrong information was entered? We always include our Bug ID when we commit a changeset. For instance: hg commit -m "Bug 14585: LastName field should be mandatory" But If I put the wrong bug ID, is there a way (through an extension maybe) to fix the comment once the changeset has been committed (and possibly pushed)?

• Can Python's set absence of ordering be considered random order?

  - by Chuim

  Hello people. I'd like to know if the absence of element ordering of the Python's built-in set structure is "random enough". For instance, taking the iterator of a set, can it be considered a shuffled view of its elements? (If it matters, I'm running Python 2.6.5 on a Windows host.)

• C# Get Keys from a Dictionary<string, Stream>

  - by alex

  Suppose I have a Dictionary like so: Dictionary<string, Stream> How can I get a list (or IEnumerable or whatever) of JUST the Keys from this dictionary? Is this possible? I could enumerate the dictionary, and extract the keys one by one, but I was hoping to avoid this. In my instance, the Dictionary contains a list of filenames (file1.doc, filex.bmp etc...) and the stream content of the file from another part of the application.

• Is it possible to create a FIPS 140-2 compliant server in Perl?

  - by Nayruden

  The question is pretty simple, is it possible to create a FIPS 140-2 compliant server in Perl? Especially, is it possible without modifying any of the C code for the modules? If it's not possible in straight Perl, what would be the easiest way to go about it from a C perspective? I'm basically creating a mini-httpd that only serves up a single file, but due to security restrictions it needs to be served up on SSL under FIPS compliance.

• Is web-browser to Excel interprocess communication possible

  - by Abiel

  Is is possible to write a browser plugin (one that requires the user to install something is OK) that would allow interprocess communication between the browser and a running instance of Excel (on Windows)? For example, suppose I want the user to be able to click something within their browser, and then have a piece of text drop into the selected cell in Excel as a result. This is certainly possible to do with a regular desktop application and Excel, but I'm not sure if it is possible with a browser, for security reasons.

• Merging .NET assemblies on Windows Store / Phone 8 / Portable Class Library

  - by Gabriel S.

  Is there a way to embed multiple dependent assemblies into a single one for projects written on the following platform types: Windows Store Apps, Windows Phone 8, Portable Class Library? I know that for regular .Net projects there is ILMerge, but on the aforementioned project types it doesn't work. Embedding assemblies as resources and then manually resolving the references using AppDomain.CurrentDomain.AssemblyResolve is not possible either, since AppDomain is not available in these types of project.

• How Do I grep For non-ASCII Characters in UNIX

  - by Peter Conrey

  I have several very large XML files and I'm trying to find the lines that contain non-ASCII characters. I've tried the following: grep -e "[\x{00FF}-\x{FFFF}]" file.xml But this returns every line in the file, regardless of whether the line contains a character in the range specified. Do I have the syntax wrong or am I doing something else wrong? I've also tried: egrep "[\x{00FF}-\x{FFFF}]" file.xml (with both single and double quotes surrounding the pattern).

• Tomcat Load Balalncing - Programatic Parameter Based ??

  - by Gala101

  Here's the scenario: Many users access an application (running on tomcat), the user's data is segmented into multiple databases, say each db containing 1000 user's data. Now is it somehow possible to have 100s of tomcat servers running on 'inexpensive' PC class machines with each connecting to a single db, with user's session getting passed to appropriate tomcat and becoming 'Sticky' there. Can have some sort of 'gateway' deciding which user goes where and doing the load-balancing appropriately. Would make a great scalability solution :)

• Multihomed Windows server and DNS resolution

  - by Mike K.

  I have a Windows 2008 server with two IP addresses assigned to a single NIC. The DNS settings are setup to register the connections's addresses on the DNS server. nslookup shows both IP addresses for the server name. How is name resolution done in this case, i.e. which IP address does the DNS server return for a host lookup? Or does it return both, and the client selects one of the addresses?
