  • [PHP] Dynamic cron jobs?

    - by Frankie Laguna
    I'm writing a script that needs to be called at a random time during the day, but am not sure how to accomplish this. I don't want to waste server resources to run a cron job every minute. I want the script to be called at random, so generating the random times for say a month in advance and then creating cron jobs for each of them isn't what I'm looking for. Also this script only needs to be executed once a day. Thanks in advance!

  • Converting an empty string into nil in Ruby

    - by adi92
    I have a string called word and a function called infinitive such that word.infinitive would return another string on some occasions and an empty string otherwise I am trying to find an elegant ruby one line expression for the code-snippet below if word.infinitive == "" return word else return word.infinitive Had infinitive returned nil instead of "", I could have done something like (word.infinitive or word) But since it does not, I can't take advantage of the short-circuit OR Ideally I would want 1) a single expression that I could easily embed in other code 2) the function infinitive being called only once 3) to not add any custom gems or plugins into my code

  • Is there a way to keep a selenium session persistent accross multiple tests?

    - by Nick
    I am testing a django application's frontend with selenium and that's first time I use it. I have multiple tests that test things after user logged in. I want them to be separate tests, but I want to have only log in once, is that possible? (As oppose to what I do right now: I log in first, then execute my testing actions of test1, then log in again and execute my testing actions for test2, etc.)

    - by teepusink
    Hi, Once I connect my iPhone to my computer, is there anyway I can look at the directory structure on the phone? Would it work like a USB device for example and let me copy files without using iTunes but just drag and drop through the Finder on a Mac? Thanks, Tee

  • .NET framework deprecated interfaces and attributes. What was your biggest refactoring due to lack o

    - by Andrew Florko
    Some .net-framework interfaces and attributes become obsolete and deprecated since new framework version appears. I am warned that such code may be removed or become unpredictable in next versions but have you ever faced the situation when you were forced to refactor code because code came uncompilable or start to behave weird? What was you biggest refactoring? Or maybe Microsoft always continued to support api's once they were published? Thank you in advance!

  • Multi-property "transactions" in Core Data / NSManagedObject / NSFetchedResultsController?

    - by Martijn Thé
    Hi, Is it possible to set multiple properties of an NSManagedObject and have the NSFetchedResultsController call controllerDidChangeContent: only once? In other words, is it possible to say something like: [managedObject beginChanges]; [managedObject setPropertyA:@"Foo"]; [managedObject setPropertyB:@"Bar"]; [managedObject commitChanges]; and then have the NSFetchedResultsController call controllerDidChangeContent: (and the other methods) only one time? Thanks!

  • Placeholder for UITextView

    - by Gill Bates
    Anyone ever implements something in UITextView that stopping it from receiving future inputs when the text length is smaller than certain threshold? I plan to implement a textview like we have in the mail composer interface. We have a placeholder "Subject" there, and the cursor starts after. Placeholder in UITextView Inspired from this question, I wonder if there are some methods which could be used to stop changing the text in the UITextView once the cursor is moving back to the placeholder string. Any ideas?

    - by btol45
    We're running a Django website with rough 45 install Django admin classes. The handler is mod_fastcgi. Every once in a while about half the admins disappear from /admin/ screen.

  • Can the memory used by MKMapView be released some how?

    - by gdr
    I am using an MKMapView in my iPhone application. When I load this view, the activity monitor instrument shows that the real memory of my App is increasing significantly. It keeps going up as you move the map around or zoom in and out. Once the View controller that loads this view is removed, the memory that was allocated due to the usage of the mapView does not get freed up. Is there something that can be done to get all this memory back?

  • How do I make a full screen scrolling messagebox or window?

    - by chobo2
    Hi First let me start of saying I know absolutely nothing about c++ and I am really just more interested in getting this to work then learning c++(I got enough on my plate to learn). So basically I am trying to make a terms of service for my windows mobile 6 professional application but it seems I need to use c++ to do it. After hours of searching I found a solution but it developed for windows mobile standard. So they somehow used c++ to make a message box and on standard devices(ie non touch screen phones) the message box can have like scrolling. For some reason this is not the case with professional devices(touch screen devices). So my message box goes off the page and you can never accept or decline the terms. So your stuck and on the screen forever till you do some sort of soft restart. http://www.mobilepractices.com/2008/10/setupdll-sample-and-walkthrough-terms.html The above link is the tutorial but here is the actual file that seems to display the message. #include "stdafx.h" #include "ce_setup.h" // This is a variable containing the text to be displayed // in the Terms & Conditions dialog TCHAR Message[] = _T("TERMS & CONDITIONS\r\n ") _T("Selecting YES you're accepting our terms & conditions.\r\n") _T("This is just a sample application.\r\n") _T("From http://www.mobilepractices.com\r\n") _T("You can replace this text with your own.\r\n") _T("We're using a setup.dll to show this dialog.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Extra line to force vertical scrollbar.\r\n") _T("Last line.\r\n") ; // This function will be called when the user // tries to install the cab. According to its return // value the installation continues or is cancelled. // As this could be called more than once // (i.e. if there is not enough space on the target) // we should take care about fFirstCall parameter // to show the dialog only once. codeINSTALL_INIT Install_Init( HWND hwndParent, BOOL fFirstCall, BOOL fPreviouslyInstalled, LPCTSTR pszInstallDir ) { if (!fFirstCall || ::MessageBoxW(0, Message, _T("SplashScreenSample") , MB_YESNO) == IDYES) return codeINSTALL_INIT_CONTINUE; else return codeINSTALL_INIT_CANCEL; } So I want to change this to something that can scroll. Can I use like a panel control since I know what has scroll or something else? Thanks

  • Easy way to convert a string of 0's and 1's into a character? Plain C

    - by Nick
    I'm doing a steganography project where I read in bytes from a ppm file and add the least significant bit to an array. So once 8 bytes are read in, I would have 8 bits in my array, which should equal some character in a hidden message. Is there an easy way to convert an array of 0's and 1's into an ascii value? For example, the array: char bits[] = "0,1,1,1,0,1,0,0" would equal 't'. Plain C
