  • How can I make this Perl regex work?

    - by Geo
    I have this line ( it's a single line, SO makes it seem like 2 ): /Od /D "WIN32" /D "_DEBUG" /FD /EHa /MDd /Fo"Debug" /Fd"Debug\vc80.pdb" /W3 /c /Zi /clr /TP .\main.cpp" And I want to extract the .\main.cpp. I thought the following would do the trick: if($string =~ /.*\s+(.*)$/i) { print "matched ",$1,"\n"; } because this same regex works in Ruby, and extracts the string I required. How can I get it working?

    - by JasonHorner
    I have a file that is tab delimited. I would like a powershell script that counts the number of tabs in each line.

I would like it to print a single number for each line in the file.

  • Using AMQP to collect events

    - by synapse
    Does AMQP has any advantages over an ad-hoc implementation for a simple stats gathering scenario? It works like this - clients send events (more than we care to put into persistent storage) to (several) web workers, the workers aggrregate them and write to a single database. I don't think I should consider using AMQP for this because I'll still need web workers to receive events from clients through HTTP and to publish them. Am I missing something?

  • How do you create a transaction that spans multiple statements in Python with MySQLdb?

    - by Fast Fish
    I know that with an InnoDB table, transactions are autocommit, however I understand that to mean for a single statement? For example, I want to check if a user exists in a table, and then if it doesn't, create it. However there lies a race condition. I believe using a transaction prior to doing the select, will ensure that the table remains untouched until the subsequent insert, and the transaction is committed. How can you do this with MySQLdb and Python?

  • How to lock files in a tomcat web application?

    - by yankee
    The Java manual says: The locks held on a particular file by a single Java virtual machine do not overlap. The overlaps method may be used to test whether a candidate lock range overlaps an existing lock. I guess that if I lock a file in a tomcat web application I can't be sure that every call to this application is done by a different JVM, can I? So how can I lock files within my tomcat application in a reliable way?

  • How to perform add/update of a model object that contains EntitySet

    - by David Liddle
    I have a similar concept to the SO questions/tags scenario however am trying to decide the best way of implementation. Tables Questions, QuestionTags and Tags Questions QuestionTags Tags --------- ------------ ---- QID QID TID QName TID TName When adding/updating a question I have 2 textboxes. The important part is a single textbox that allows users to enter in multiple Tags separated by spaces. I am using Linq2Sql so the Questions model has an EntitySet of QuestionTags with then link to Tags. My question is regarding the adding/updating of Questions (part 1), and also how to best show QuestionTags for a Question (part 2). Part 1 Before performing an add/update, my service layer needs to deal with 3 scenarios before passing to their respective repositories. Insert Tags that do not already exist Insert/Update Question Insert QuestionTags - when updating need to remove existing QuestionTags Here is my code below however started to get into a bit of a muddle. I've created extension methods on my repositories to get Tags WithNames etc. public void Add(Question q, string tags) { var tagList = tags.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries).ToList(); using (DB.TransactionScope ts = new DB.TransactionScope()) { var existingTags = TagsRepository.Get() .WithName(tagList) .ToList(); var newTags = (from t in tagList select new Tag { TName = t }).Except(existingTags, new TagsComparer()).ToList(); TagsRepository.Add(newTags); //need to insert QuestionTags QuestionsRepository.Add(q); ts.Complete(); } } Part 2 My second question is, when displaying a list of Questions how is it best to show their QuestionTags? For example, I have an Index view that shows a list of Questions in a table. One of the columns shows an image and when the user hovers over it shows the list of Tags. My current implementation is to create a custom ViewModel and show a List of QuestionIndexViewModel in the View. QuestionIndexViewModel { Question Question { get; set; } string Tags { get; set; } } However, this seems a bit clumsy and quite a few DB calls. public ViewResult Index() { var model= new List<QuestionIndexViewModel>(); //make a call to get a list of questions //foreach question make a call to get their QuestionTags, //to be able to get their Tag names and then join them //to form a single string. return View(model); } Also, just for test purposes using SQL Profiler, I decided to iterate through the QuestionTags entity set of a Question in my ViewModel however nothing was picked up in Profiler? What would be the reason for this?

  • jquery binding multiple events, and pass data

    - by mkoryak
    I know we can have this in 1.4: $("a").bind({ click : clickFn, mouseover: mouseFn }); and that is nice and i would like to use it, but it seems like there is no way to pass extra data to events bound this way, it needs to be done the 'old way': $("a").bind("click", {"some":"data"}, clickFn); Question: how can i pass the extra data to my event call backs and bind multiple events in a single bind at the same time?

  • Exploded (unpacked) EAR vs. Packaged EAR file?

    - by Adam
    In my office we use exploded EAR's (and inside them exploded WAR directories) for our test environments, and then a packaged one for production. I've yet to find a good explanation of the reason behind this though. I understand it's easier from a deployment perspective to push out a single file during builds, but it prevents us from doing things like property file changes without doing complete rebuilds (we could skip the compiles, but our environment currently binds the compile and jar processes together). What are the major advantages / disadvantages between these two configurations?

  • DRY-ing very similar specs for ASP.NET MVC controller action with MSpec (BDD guidelines)

    - by spapaseit
    Hi all, I have two very similar specs for two very similar controller actions: VoteUp(int id) and VoteDown(int id). These methods allow a user to vote a post up or down; kinda like the vote up/down functionality for StackOverflow questions. The specs are: VoteDown: [Subject(typeof(SomeController))] public class When_user_clicks_the_vote_down_button_on_a_post : SomeControllerContext { Establish context = () => { post = PostFakes.VanillaPost(); post.Votes = 10; session.Setup(s => s.Single(Moq.It.IsAny<Expression<Func<Post, bool>>>())).Returns(post); session.Setup(s => s.CommitChanges()); }; Because of = () => result = controller.VoteDown(1); It should_decrement_the_votes_of_the_post_by_1 = () => suggestion.Votes.ShouldEqual(9); It should_not_let_the_user_vote_more_than_once; } VoteUp: [Subject(typeof(SomeController))] public class When_user_clicks_the_vote_down_button_on_a_post : SomeControllerContext { Establish context = () => { post = PostFakes.VanillaPost(); post.Votes = 0; session.Setup(s => s.Single(Moq.It.IsAny<Expression<Func<Post, bool>>>())).Returns(post); session.Setup(s => s.CommitChanges()); }; Because of = () => result = controller.VoteUp(1); It should_increment_the_votes_of_the_post_by_1 = () => suggestion.Votes.ShouldEqual(1); It should_not_let_the_user_vote_more_than_once; } So I have two questions: How should I go about DRY-ing these two specs? Is it even advisable or should I actually have one spec per controller action? I know I Normally should, but this feels like repeating myself a lot. Is there any way to implement the second It within the same spec? Note that the It should_not_let_the_user_vote_more_than_once; requires me the spec to call controller.VoteDown(1) twice. I know the easiest would be to create a separate spec for it too, but it'd be copying and pasting the same code yet again... I'm still getting the hang of BDD (and MSpec) and many times it is not clear which way I should go, or what the best practices or guidelines for BDD are. Any help would be appreciated.

  • polymorphism and interfaces

    - by mixm
    if i have two classes x and y, both extend class w. and x implementing interface z. if i have methods doSomething(w object) and doSomething(x object), what would happen if i call doSomething(x)? edit: im implementing this on java, more specifically on android. im asking this because some classes which implement a specific interface mostly does the same thing when doSomething() is called. but there are special cases which i would like to single out.

  • How can you dispatch on request method in Django URLpatterns?

    - by rcampbell
    It's clear how to create a URLPattern which dispatches from a URL regex: (r'^books/$', books), where books can further dispatch on request method: def books(request): if request.method == 'POST': ... else ... I'd like to know if there is an idiomatic way to include the request method inside the URLPattern, keeping all dispatch/route information in a single location, such as: (r'^books/$', GET, retrieve-book), (r'^books/$', POST, update-books), (r'^books/$', PUT, create-books),
