  • Is there a way to prevent Triggers from being disabled?

    - by HAdes
    I have a trigger on a table that should never be disabled. It performs certain checks and there have been occasions when other developers have disabled it to get around it.

  • mod_rewrite with anchor link

    - by Graham
    Hi, thanks for looking. I know you can't redirect anchor URLs to another page, but is it possible to redirect a URL to only a single anchor? So http://www.example.com/video/{title} always gets sent to http://www.example.com/video.php?title={title}#player The only thing that changes is the title, anchor is always the same... I need to redirect to a certain slide on a coda slider

  • Passing parameter to base class constructor or using instance variable?

    - by deamon
    All classes derived from a certain base class have to define an attribute called "path". In the sense of duck typing I could rely upon definition in the subclasses: class Base: pass # no "path" variable here def Sub(Base): def __init__(self): self.path = "something/" Another possiblity would be to use the base class constructor: class Base: def __init__(self, path): self.path = path def Sub(Base): def __init__(self): super().__init__("something/") What would you prefer and why? Is there a better way?

  • Does watir's browser.text.include? count text inside invisible divs? If so, how to search only for v

    - by karlthorwald
    Does watir's browser.text.include? count text inside invisible divs? If so, how to search only for visible text? I put all the instructions into the html from the beginning and use jQuery to hide and unhide the relevant parts. How can I use watir's waiter to wait for only text that is visible? My problem is, that the waiter always returns true, even before I have shown a certain text.

  • Which data structures and algorithms book should I buy?

    - by Hei
    I know C and C++ and I have some experience with Java, but I don't know too much about Algorithms and Data Structures. I did a search on Amazon, but I don't know what book should I choose. I don't want a book which put its basis only on the theoretic part; I want the practical part too (probably more than the theoretical one :) ). I don't want the code to be implemented in a certain language, but if is in Java, probably I would happier. :)

  • Searching a process' memory on Linux

    - by Matt Joiner
    How can I search the memory state of an process in Linux? Specifically I wish to identify certain regions of interest, and peek at them at regular intervals, possibly occasionally poking new values. I suspect an answer may involve calls to ptrace(), and reading /proc/[pid]/mem, but need more to go on.

  • How to cancel a touch sequence

    - by Alex
    I have an UIImage view that responds to touch events. I want to cancel the touch sequence if the touch goes outside of certain bounds. How can I do that? I know that I can inspect the coordinates of the touch object, what I don't know is how to cancel the sequence. I don't see any event in the API that allows for that.

  • Simulating a missing gem in Ruby unit tests

    - by ktex
    Is there any way to simulate the absence of a gem for certain unit tests, short of actually uninstalling and then reinstalling the gem during testing? I am writing a command line utility, and want to make sure that my tests cover cases where a user may not have all of the gems that I support. For instance, I am using fsevents — a Leopard-specific package for monitoring filesystem events — that will never be present on other systems, as well as a growl gem that's purely optional.
