• 7zip compressing the same file slightly different results

  - by MicMit

  I am using 7za command line File dfat_clist.xls in directory 2010_05_07 The same dfat_clist.xls in directory 2010_05_08 Zips are created in the same directory where the xls files resides string pars = "a -tzip \"" + Path.Combine( SourceDir,ZipName) + "\" \"" + Path.Combine( SourceDir, Mask ) + "\"" ; Parameters given to 7za are full paths for zip and xls.

• How do I see the whole HTTP request in Rails

  - by akafazov

  Hi, I have a Rails application but after some time of development/debugging I realized that it would be very helpful to be able to see the whole HTTP request in the logfiles - log/development.log, not just the parameters. I also want to have a separate logfile based on user, not session. Any ideas will be appreciated! Angel

• Query a stored procedure for it's parameter names and types

  - by ho1

  Is there any easy way to query a stored procedure (Oracle - PL/SQL) for what parameters it expects? I know that I can query USER_SOURCE to get the whole procedure but I'd then have to parse the whole procedure, and if the parameter is of type [table].[column]%TYPE I'd then have to query the table schema as well. Either using just sql or via ODP.Net.

  Given a few sample points on a bézier curve, is it possible to work out the set of possible parameters of the curve? In my specific application there is a limited set of endpoints the curve may have, so I want to generate the set of possible curves, enumerate all of them and pick out all the ones which may end on a valid end point.

• Refactoring c / c++ in vim (e.g. method extraction like in eclipse.)

  - by bjarkef

  Hi Is there any plugins or built-in method in vim for performing refactoring on c or c++ code, something like the refactoring tools in eclipse? I'm especially keen on the extract method refactoring tool from eclipse that will determine parameters from new method and typically also guess a variable to use as return value.

• Scraping Google docs (can't use API)

  - by Andy Waite

  I'm building an iPhone app which needs a peice of meta data from a user's Google Spreadsheet. Unfortunately the meta data I need is not exposed by the API, so I will need to scrape it from the document's HTML source (it would not be present in any of the exported variants). Is there anyway to include authentication parameters in a call such as: http://spreadsheets.google.com/ccc?key=abc123&username=...&password=...

• Java - is this an idiom or pattern, behavior classes with no state

  - by Berlin Brown

  I am trying to incorporate more functional programming idioms into my java development. One pattern that I like the most and avoids side effects is building classes that have behavior but they don't necessarily have any state. The behavior is locked into the methods but they only act on the parameters passed in. The code below is code I am trying to avoid: public class BadObject { private Map<String, String> data = new HashMap<String, String>(); public BadObject() { data.put("data", "data"); } /** * Act on the data class. But this is bad because we can't * rely on the integrity of the object's state. */ public void execute() { data.get("data").toString(); } } The code below is nothing special but I am acting on the parameters and state is contained within that class. We still may run into issues with this class but that is an issue with the method and the state of the data, we can address issues in the routine as opposed to not trusting the entire object. Is this some form of idiom? Is this similar to any pattern that you use? public class SemiStatefulOOP { /** * Private class implies that I can access the members of the <code>Data</code> class * within the <code>SemiStatefulOOP</code> class and I can also access * the getData method from some other class. * * @see Test1 * */ class Data { protected int counter = 0; public int getData() { return counter; } public String toString() { return Integer.toString(counter); } } /** * Act on the data class. */ public void execute(final Data data) { data.counter++; } /** * Act on the data class. */ public void updateStateWithCallToService(final Data data) { data.counter++; } /** * Similar to CLOS (Common Lisp Object System) make instance. */ public Data makeInstance() { return new Data(); } } // End of Class // Issues with the code above: I wanted to declare the Data class private, but then I can't really reference it outside of the class: I can't override the SemiStateful class and access the private members. Usage: final SemiStatefulOOP someObject = new SemiStatefulOOP(); final SemiStatefulOOP.Data data = someObject.makeInstance(); someObject.execute(data); someObject.updateStateWithCallToService(data);

• Using Ruby, what is the most efficient way to check if any key in a hash matches any values within a

  - by Jason

  I want to compare the keys in a hash of parameters against an array of elements for a match. For example: params = {"key1", "key2", "key3"} params_to_match = ["key2","key3"] I could do this, but I'm sure there is a much more elegant way to acheive the same result params.each_key{|key| if params_to_match.include?(key.to_s) return end }

• What do you call this functional language feature?

  - by Jimmy

  ok, embarrassing enough, I posted code that I need explained. Specifically, it first chains absolute value and subtraction together, then tacks on a sort, all the while not having to mention parameters and arguments at all, because of the presense of "adverbs" that can join these functions "verbs" What (non-APL-type) languages support this kind of no-arguments function composition (I have the vague idea it ties in strongly to the concepts of monad/dyad and rank, but its hard to get a particularly easy-to-understand picture just from reading Wikipedia) and what do I call this concept?
