• How would I start integrating pyflakes with Hudson

  - by dd

  We use Hudson for continuous integration with the Violations Plugin which parses our output from pylint. However, pylint is a bit too strict, and hard to configure. What we'd rather use is pyflakes which would give us the right level of "You're doing it wrong."

• The simplest concurrency pattern

  - by Ilya Kogan

  Please, would you help me in reminding me of one of the simplest parallel programming techniques. How do I do the following in C#: Initial state: semaphore counter = 0 Thread 1: // Block until semaphore is signalled semaphore.Wait(); // wait until semaphore counter is 1 Thread 2: // Allow thread 1 to run: semaphore.Signal(); // increments from 0 to 1 It's not a mutex because there is no critical section, or rather you can say there is an infinite critical section. So what is it?

• Find Specific Rows

  - by H07R0D

  I'm trying to build a rather specific query to find a set of user_ids based on topics they have registered to. Unfortunately it's not possible to refactor the tables so I have to go with what I've got. Single table with user_id and registration_id I need to find all user_ids that have a registration_id of (4 OR 5) AND NOT 1 Each row is a single user_id/registration_id combination. My SQL skills aren't the best, so I'm really scratching my brain. Any help would be greatly appreciated.

• Scheduled task to open URL

  - by Jeremy Stein

  At a certain time each day, I'd like my browser to pop open a tab to a certain URL. My goals: 1. be able to set the URL from the scheduled task 2. use the default browser (rather than hard-coding it) I can't seem to accomplish both of these goals at once. I'll post my partial solutions as answers, but I'm hoping someone will have something better.

• Date conversion in Java

  - by llm

  How can I take a string in a format such as: 2008-06-02 00:00:00.0 and convert it to: 02-Jun-2008? Can I somehow take the original string, convert it to a Date object, then use a formatter to get the final output (rather than parsing the string myself)? Thanks!

• How can I configure vim so that when I send the process a USR1 signal it saves and quits (as opposed

  - by Philip Hallstrom

  Here's my situation. I have a bunch of vim processes open. Rather than go through one by one and save/quite (:x!) I'd like to send all of the processes a signal - say USR1 - and instead of having it create a recovery .swp file, I'd like it to save the file and exit normally. Possible?

• How can I test helpers blocks in Sinatra, using Rspec ?

  - by julien

  I'm writing a sinatra app and testing it with rspec and rack/test (as described on sinatrarb.com). It's been great so far, until I moved some rather procedural code from my domain objects to sinatra helpers. Since then, I've been trying to figure out how to test these in isolation ?

• Defining a class with specific style dynamically in jQuery

  - by Acorn

  Is it possible to define a class with specific style attributes dynamically with jQuery, rather than setting the style of all elements with that class? I could set the attributes of the class at the end of the script once all the elements have been created, but is that the best way to go about it? If I define the style of the class with $('.class').css('property','value'); at the beginning of the script, nothing would happen because the elements with class .class haven't been created yet, right?

• Data Access example using Entity Framework

  - by Dan

  Does anyone know of or having any good examples of how to use Entity Framework version 2 in the Data Access layer and put an interface on it so the business layer uses the interface rather than knowing about EF? I have found some examples but they are all from 2009 and I'm not sure how they relate to Entity Framework version 2.

• Display regular street map on Google Earth

  - by carrier

  I'm writing an application that displays data using Google Earth. In certain situations, it would be more convenient if, rather than displaying satellite images, the surface of the earth would look more like the 'regular map' on Google Maps. Is this possible?

• CVS branch name from tag name

  - by Jamie

  I have a number of modules in CVS with different tags. How would I go about getting the name of the branch these tagged files exist on? I've tried checking out a file from the module using cvs co -r TAG and then doing cvs log but it appears to give me a list of all of the branches that the file exists on, rather than just a single branch name. Also this needs to be an automated process, so I can't use web based tools like viewvc to gather this info.

• How can I Monitor the Performance of Individual Apps on Windows?

  My XP machine has become terribly slow and I want to identify the application at fault. It seems to be related to disk access rather than processor hogging. I can look at the task manager to get a good idea but it's not ideal. I was wondering if there was some application that can monitor all aspects of processes effectively. Is Process Explorer my only hope?

• Get individual query parameters from Uri

  - by Ghostrider

  I have a uri string like: http://example.com/file?a=1&b=2&c=string%20param Is there an existing function that would convert query parameter string into a dictionary same way as ASP.NET Context.Request does it. I'm writing a console app and not a web-service so there is no Context.Request to parse the URL for me. I know that it's pretty easy to crack the query string myself but I'd rather use a FCL function is if exists.

• jQuery Stop non-css animation

  - by Mark

  I'm trying to stop a non-css animation: http://jsbin.com/aqute4/4/edit Button 1 starts the animation nicely, totally lost on how to stop it though, since .stop() seems to need a DOM element... rather than a random object. Thanks in advance. PS: Original code comes from: http://james.padolsey.com/javascript/fun-with-jquerys-animate/

• Development Environment for Testing MySQL Replication

  - by Dave Morris

  Is there an easy way to setup an environment on one machine (or a VM) with MySQL replication? I would like to put together a proof of concept of MySQL replication with one Master write instance and two slave instances for reads. I can see doing it across 2 or 3 VMs running on my computer, but that would really bog down my system. I'd rather have everything running on the same VM. What's the best way to proof out scalability solutions like this in a local dev environment? Thanks for your help, Dave

• Joomla - output ' instead of \'

  - by Peter Perhác

  Hello there, all of my Joomla site's contents shows apostrophes as \' instead of just '. Now my head is spinning from looking at all the million places where individual components and joomla itself does add/remove slashes and deals with magic quotes and all of this... I also found that one can rather easily write one's own OutputFilter for the patTemplate, so I thought maybe I would just do a str_replace of all \' to '. Doesn't sound right. How to deal with these apostrophes?

  Hi, Has anyone encountered something like this? I was expecting file.txt to be inside "testbranch/src/" folder after executing the command written command. But I get entry at "testbranch/src" to be a file type rather than directory type!
