• String concatenation produces incorrect output in Python?

  - by Brian

  I have this code: filenames=["file1","FILE2","file3","fiLe4"] def alignfilenames(): #build a string that can be used to add labels to the R variables. #format goal: suffixes=c(".fileA",".fileB") filestring='suffixes=c(".' for filename in filenames: filestring=filestring+str(filename)+'",".' print filestring[:-3] #now delete the extra characters filestring=filestring[-1:-4] filestring=filestring+')' print "New String" print str(filestring) alignfilenames() I'm trying to get the string variable to look like this format: suffixes=c(".fileA",".fileB".....) but adding on the final parenthesis is not working. When I run this code as is, I get: suffixes=c(".file1",".FILE2",".file3",".fiLe4" New String ) Any idea what's going on or how to fix it?

• Sitecore - version created in other language when renaming

  - by misteraidan

  So I've got this Sitecore content item right, and it's got one version in one language "en-AU". I have 3 potential languages in the system "en", "en-AU" and "en-NZ". I rename the item, right, and Sitecore creates a new version in "en". I delete the "en" version and rename again, same result.. a new version is created .. and again... and again .. see where I'm going with this? And again! Why would it do that? I thought it was a problem with my pipeline processor, but I turned it off and it still happens! Any ideas would be welcome.

• How to ensure I can replace files in a directory?

  - by chaiguy

  I want to completely replace one directory on the file system with another directory in a temp directory. The tricky part is that the files in the folder to be replaced could be being used at any time, causing the replace operation to fail. I need to somehow wait on an exclusive lock on the directory so that I can delete all of its contents without failing, so I can then move the other directory in to replace it. To make matters potentially more difficult, the process that is likely to be using the files is my own (via a Lucene.net library and out of my hands). So it can't be a process-level lock it has to be an object-level lock. Any thoughts on how I might do this? Or should I just keep re-attempting until it succeeds? I guess that's always an option.

• XCode: compiling doesn't always replace plist?

  - by Brian Postow

  I have an application and I will sometimes just change the plist, say to change the version number. Sometimes I'll actually make a change to the code, AND the version number....in the latter case, SOMETIMES the version number of the resulting app will change, in the former it will never change. The only way I've found that surely does it right is when I delete the .app before compiling. In case it matters, the resulting app is being put in a folder that isn't in the build folder, but I doubt that that's relevant. any thoughts?

• Is it possible to destroy a CDI scope?

  - by Matt Ball

  I'm working on a Java EE application, primarily JAX-RS with a JSF admin console, that uses CDI/Weld for dependency injection with @ApplicationScoped objects. Minor debugging issues aside, CDI has worked beautifully for this project. Now I need some very coarse-grained control over CDI-injected object lifecycles. I need the ability to: Remove an injected object from the application context, or Destroy/delete/clear/reset/remove the entire application context, or Define my own @ScopeType and implementing Context in which I could provide methods to perform one of the two above tasks. I'm fully aware that this is across, if not against, the grain of CDI and dependency injection in general. I just want to know Is this remotely possible? If yes, what is the easiest/simplest/quickest/foolproofiest way to get the job done?

• When should I consider representing the primary-key ...?

  - by JMSA

  When should I consider representing the primary-key as classes? Should we only represent primary keys as classes when a table uses composite-key? For example: public class PrimaryKey { ... ... ...} Then private PrimaryKey _parentID; public PrimaryKey ParentID { get { return _parentID; } set { _parentID = value; } } And public void Delete(PrimaryKey id) {...} When should I consider storing data as comma-separated values in a column in a DB table rather than storing them in different columns?

• Best computer-science universities in Europe?

  - by Tom

  I am in 11th grade and only one year left when I finish my school. I am sure I want to dedicate my life to programming. In my country the education's level is not so high as in Europe, so I want to emigrate and study not just for a diploma, but for knowledge too. So, what universities would you suggest me which has subject Computer-Science? I prefer web programming. Please do not delete this message though it is quite offtopic, but it's the best place for me to get suggestions from advanced programmers who have already finished their university. And I hope here comes also teenagers who can make the best decision choosing university. Thank you. Please read the whole my message before voting to close this thread, thanks.

• SSIS process files from folder

  - by RT

  Background: I've a folder that gets pumped with files continuously. My SSIS package needs to process the files and delete them. The SSIS package is scheduled to run once every minute. I'm picking up the files in ascending order of file creation time. I'm building an array of files and then processing-deleting them one at a time. Problem: If an instance of my package takes longer than one minute to run, the next instance of the SSIS package will pick up some of the files the previous instance has in its buffer. By the time the second instance of teh package gets around to processing a file, it may already have been deleted by the first instance, creating an exception condition. I was wondering whether there was a way to avoid the exception condition. Thanks.

• How do you set the "global delimiter" in Excel using VBA (or unicorns)?

  - by DanM

  I've noticed that if I use the text-to-columns feature with comma as the delimiter, any comma-delimited data I paste into Excel after that will be automatically split into columns. This makes me think Excel must have some kind of global delimiter. If this is true, how would I set this global delimiter using Excel VBA? Is it possible to do this directly, or do I need to "trick" Excel by doing a text-to-columns on some junk data, then delete the data? My ultimate goal is to be able to paste in a bunch of data from different files using a macro, and have Excel automatically split it into columns according to the delimiter I set.

• Align table columns HTML

  - by Luigi Tiburzi

  I finally was able to align the columns in the tables of a page of my website. Though I found the solution I don't understand it. This is a fiddle I prepared. If you delete display: block from the CSS the columns are centered perfectly. The fact is that I don't understand what that instruction is causing problems, doesn't it means that elements are displayed as block elements? Shouldn't it cause the elements (the raw in particular) to fill an entire line? Thanks for your explanation

• Set Java Application's virtual machine max memory without access to VM parameters because of custom

  - by Tom

  I'm using a Java application which allows you to import custom files. On import, these files are loaded into memory. The problem is that the files I want to import are very big, this causes an OutOfMemory exception. The crash log also informs me that the VM was started with the java parameter "-Xmx512m", I want to alter this to "-Xmx1024m" so that I got double the memory available. The problem is that this application is using it's own JRE folder and that there's a launcher written in C which is calling the jvm.dll file. In any way, java.exe or javaw.exe are never called and thus I cannot set these parameters myself (if I delete these executables it doesn't matter, can still run the application - this is not the case with the dll). So, my question is, can I set this VM parameter in an other way? I'm even willing to alter the JRE files if there is no other way.

• Checkbox vs Two Radio Buttons - Which one is more usable?

  - by Engram

  I'm currently working on some setting screens, most of which contain a 2 column form with a preference question on the left, and a form element on the right. The questions are things like: Can add/edit other users? Can delete clients? Obviously this setting is a binary setting and most UI "experts" would insist that a checkbox is the appropriate form element to use. However, when I mocked up the form with the checkboxes it looked unfriendly and it seemed hard to relate the state of the checkbox back to the question. I changed the form to use two radio buttons instead: Yes o No Personally I find this easier to process, as the options are actually answers to the question posed on the left. In terms of clicking it makes no difference to the user, it's a single click each time to change the setting. What do you think of this use of radio buttons? Is this better or worse than a checkbox and why?

• How do you refresh the contents of an R gWidget?

  - by Richie Cotton

  I'm creating a GUI in R using gWidgets (more specifically gWidgetstcltk). I'd like to know how to update the contents of selection-type widgets, such as gdroplist and gtable. I currently have a rather hackish method of deleting the widget and re-creating it. I'm sure there's a better way. This simple example displays all the variables in the global environment. library(gWidgets) library(gWidgetstcltk) create.widgets <- function() { grp <- ggroup(container = win) ddl <- gdroplist(ls(envir = globalenv()), container = grp) refresh <- gimage("refresh", dirname = "stock", container = grp, handler = function(h, ...) { if(exists("grp") && !is.null(grp)) { delete(win, grp) rm(grp) } grp <- create.widgets() } ) } win <- gwindow() grp <- create.widgets()

• Rails: render a partial from a plugin

  - by Sam

  I'm getting a missing template error after I try rendering a partial from a plugin. I have included the files with the following: %w{ models controllers helpers views }.each do |dir| path = File.join(File.dirname(__FILE__), 'app', dir) $LOAD_PATH << path ActiveSupport::Dependencies.load_paths << path ActiveSupport::Dependencies.load_once_paths.delete(path) end The Models are getting loaded, but as for other things I'm not sure what's going on. The helpers are not getting loaded too because I just copied the contents of the partial from the plugin instead of the render :partial = and then it came up with a helper error. Question is how to be able to :render :partial = from the views folder in my plugin

• vim - how am I suppose to read this command to remove all blanks at the end of a line

  - by whaley

  I happened across this page full of super useful and rather cryptic vim tips at http://rayninfo.co.uk/vimtips.html. I've tried a few of these and I understand what is happening enough to be able to parse it correctly in my head so that I can possibly recreate it later. One I'm having a hard time getting my head wrapped around though are the following two commands to remove all spaces from the end of every line :%s= *$== : delete end of line blanks :%s= \+$== : Same thing I'm interpreting %s as string replacement on every line in the file, but after that I am getting lost in what looks like some gnarly variation of :s and regex. I'm used to seeing and using :s/regex/replacement. But the above is super confusing. What do those above commands mean in english, step by step?

• JSF - Session Bean restart on logout and login

  - by Ben

  Hi, I have a web application with a backing bean which has the context of the current logged in user. It is implemented on JSF. When the user logs out he is forwarded to a login screen (in another JSP page). I would like the current session to be erased when that happens and a new one to be created the next time the user logs in and enters the application. My question is - how do you delete a session? (I guess the new session will be created automatically the next time the user enters the link) This is kinda newb i guess, but I couldn't find a solution for this. Thanks for the Help!
