• MySQL Split Time Ranges into Smaller Chunks

  - by Neren

  Hello all, I've recently been tasked with finishing a PHP/MySQL web app when the developer quit last week. I'm no MySQL expert, so I apologize if this is an intensely simple question. I've searched SO for the better part of two days trying to find a relatively easy solution to my problem, which is as follows. Problem in a Nutshell: I have a MySQL table full of start and end datetime (GMT -5) & UNIX Timestamp values covering durations of irregular length and need to break/split/divide them into more-regular time chunks (5 minutes). I'm not after a count of row entries per time chunk/bucket/period, if that makes any sense. Data Example: started, ended, started_UNIX, ended_UNIX 2010-10-25 15:12:33, 2010-10-25 15:47:09, 1288033953, 1288036029 What I'm hoping to get: 2010-10-25 15:12:33, 2010-10-25 15:15:00, 1288033953, 1288037700 2010-10-25 15:15:00, 2010-10-25 15:20:00, 1288037700, 1288038000 2010-10-25 15:20:00, 2010-10-25 15:25:00, 1288038000, 1288038300 2010-10-25 15:25:00, 2010-10-25 15:30:00, 1288038300, 1288038600 2010-10-25 15:30:00, 2010-10-25 15:35:00, 1288038600, 1288038900 2010-10-25 15:35:00, 2010-10-25 15:40:00, 1288038900, 1288039200 2010-10-25 15:40:00, 2010-10-25 15:45:00, 1288039200, 1288039500 2010-10-25 15:45:00, 2010-10-25 15:47:09, 1288039500, 1288039629 If you're interested, here's the quick & dirty on the app and why I need the data: App overview: The application receives very simple POST requests generated by a basic sensor device when its input pins go to ground, which submits an INSERT query to the database where MySQL records a timestamp (as started). When the input pins return from a grounded state, the device submits a different POST request, which causes the PHP app to submit an UPDATE query, where a modification time timestamp is inserted (as ended). My employer recently changed the periodic reporting unit of measure from Seconds "On" Per Day to Seconds "On" Per 5 Minute Interval. I had formulated what I thought would be a workable solution, but when I looked at it on paper, it looked like Rube Goldberg's nightmare constructed in MySQL, so that was out. Any suggestions as to how to break these spans into 5 minute blocks? Keeping it all in MySQL would be my preference, though I'll take any suggestions. Thank you for any suggestions you may have. Again, I apologize if this is a no-brainer. If I ask any additional questions of the SO collective consciousness in the future, I'll try to word them a bit better. Any help will be happily welcomed. Thanks, Neren

• selenium vs phpunit/lime?

  - by fayer

  i have seen the power of selenium and that it can give you the tests in different languages. so the question is, why should i use phpunit or lime (for symfony) when a solution like selenium is available? isn't it time-consuming to write all the tests by hand, when you can just use selenium? thanks.

• Checking for nulls in ASP.NET MVC Controllers

  - by Brian McCord

  Another opinion question: What is the proper (in your opinion) to check for nulls in an MVC controller. For instance, if you have an edit controller that fetches a record from the db based on an id, what do you do if that record is not found? I found this article, but I'm not sure I like that method. Do you just check for it with an if statement and redirect to a 404 page? What solution do you use?

  Dear All, I am a real newbie in programming and now I have to combine Google Maps and Dojo. Both alone are fine but when I try to implement a Google Map into a Dojo content pane which is embedded in a border-container it simply does not work.

• How to build many projects with the same svn revision number with hudson?

  - by tangens

  I'm just starting with hudson and I'd like to build my projects like my handmade solution did before: Retrieve the current svn revision number rev. Build all projects (each with individual result) with the revision number rev. Start again with step 1 regardless if there were any changes in the meantime (to detect nondeterministic errors that don't occur on every test run). How can I configure this with hudson?

• Detecting use after free() on windows.

  - by The Rook

  I'm trying to detect "Use after free()" bugs, otherwise known as "Dangling pointers". I know Valgrind can be used to detect "Use after free" bugs on the *nix platform, but what about windows? What if I don't have the source? Is there a better program than Valgrind for detecting all dangling pointers in a program? A free and open source would be preferred , but I'll use a commercial solution if it will get the job done.
