• paragraph with vertical line on its left

  - by Flavius

  Hi What is the easiest way to have a paragraph with one or with two vertical black lines on its left? I have something like this so far: \newcommand{\attention}[1]{\begin{huge}!\end{huge} #1} But instead of a huge exclamation mark, I want a vertical line, whether the paragraph is one- or multi-line.

• Completely Removing Views from memory

  - by cannyboy

  I have a view which is set up to train 'voiceprints' of words (this voiceprint code is not mine), and another view which has a slideshow which is controlled by the voiceprint. Unfortunately, these views conflict because they are still in memory. As far as I know, viewDidUnload and dealloc are only called in low-memory situations, and dealloc should not be called directly, so how do I completely remove a view. These views are within uinavigationcontrollers by the way.

• List of system tables in SQLite

  - by sovanesyan

  I am trying to filter all the tables in a SQLite database based on if they are system tables or user generated ones. So far I've found out that they are the ones with the sqlite_ prefix and AllDataTypes. Has anyone done something like this? Is there a list of them? Thanks in advance.

• Reading a SquashFS archive

  - by p-static

  (SquashFS is a compressed filesystem - http://en.wikipedia.org/wiki/SquashFS) I'm looking for a way to read a SquashFS filesystem from a program. So far, I've know about the in-kernel drivers for it, but I'm sure that a userspace library for it must exist somewhere. Any language would be fine, but C is preferred. Just mounting the filesystem and using it that way is technically possible, but I'd rather avoid that route because the application I'm looking at would involve working with at least a few dozen archives at any given time.

• Is there a good GUI SVN app for Mac (better than XCode)

  - by Lawrence Johnston

  Hey everybody, I'm looking for a more robust and fully featured GUI SVN manager for Mac than what is built into XCode (which works, but only as long as you don't need anything beyond the bare basics and doesn't work for versioning scripts and such created in other editors). I can use the terminal commands, but I'd really like the option of using a GUI. On windows I use TortoiseSVN and Visual SVN, which do pretty much everything I need, but as far as I'm aware there's nothing even remotely resembling those on the Mac side.

• What are the scenarios in which case a new class will be loaded?

  - by GK

  That is when you have any jar file attached to you your class path. then as far as i know any class from the jar is loaded for the first time when, when you create any object of that type. or If you are accessing any static member or method of that class. or when you load that by using Class.forName() method. So are there any other ways of loading a class for the first time?

• CGRect and utesting

  - by killdash10

  I am trying to add unit tests to my iPhone project in Xcode. Everything works, its great. Except when I am adding a class.m that uses CGRect (or other structs, CGPoint etc) to the unit test target (under "Compile Sources") - I am getting a compilation error: "'CGRect' undeclared (first use in this function)". I tried messing with my unit test target in various ways, but so far I haven't been able to get past this. What am I missing?

• Maximum number of cookies allowed

  - by Nouveau

  As far as Google searches tell me, the maximum allowed number of cookies depends very much on the browser, however I cannot find any recent data as to how much cookies are allowed on modern browsers. I need to store a somewhat large number of user preferences in cookies (for not-yet-registered users), so what would be the best way of doing that? (Also, those cookies would be accessed both via javascript client-side and php server-side)

• Is it possible to cancel a BeginRead on a NamedPipeServerStream without closing the pipe?

  - by romkyns

  What the title says, really. I have a named pipe. I would like to attempt a read, but if it doesn't succeed after a timeout I'd like to still be able to use the pipe afterwards. Is this possible with NamedPipeServerStream, or do I have to rethink the entire approach? So far the only way I've found of cancelling a BeginRead is by disposing of the pipe.

• SQL Server replication question.

  - by schar

  I had inherited this SQL Server where we put data in a table (Call TableA) on a database (DB-A). I can see the tableA in another database on the same server ( DB-B) gets the same data right away. Any ideas how this is implemented? I am trying to see the trace but so far no luck. Any one has an idea? At this stage I am not sure if its replication. This is a guess

• C++: Pointers and scope

  - by oh boy

  int* test( ) { int a = 5; int* b = &a; return b; } Will the result of test be a bad pointer? As far as I know a should be deleted and then b would become a messed up pointer, right? How about more complicated things, not an int pointer but the same with a class with 20 members or so?

• Is there a shorthand term for O(n log n)?

  - by jemfinch

  We usually have a single-word shorthand for most complexities we encounter in algorithmic analysis: O(1) == "constant" O(log n) == "logarithmic" O(n) == "linear" O(n^2) == "quadratic" O(n^3) == "cubic" O(2^n) == "exponential" We encounter algorithms with O(n log n) complexity with some regularity (think of all the algorithms dominated by sort complexity) but as far as I know, there's no single word we can use in English to refer to that complexity. Is this a gap in my knowledge, or a real gap in our English discourse on computational complexity?

• WinForm And Looping

  - by Soo

  I have a WinForm set up and a process that loops until a button is pressed on the form. When I try to run my code, the form does not even display. I suspect this is because the code gets stuck in the loop and doesn't get far enough to display the WinForm. How can I get the form to display and the loop to run after that point?

• Can I use Google Drive's editor interface embed in a website?

  - by Zamith

  I want to use google drive to store the files, but allow the users of my website to be able to edit them transparently, so that they don't have to go to google drive's website. Is this possible with the current API? Thus far I have only seen how to create an app for them to install in google drive, or doing something like DrEdit (https://developers.google.com/drive/examples/), which parses the files to JSON and uses the ACE editor, which is definitely not what I want.

• Checking array of censored words against user submitted content

  - by steve-o

  Hello, I have set up an array of censored words and I want to check that a user submitted comment doesn't contain any of these words. What is the most efficient way of doing this? All I've come up with so far is splitting the string into an array of words and checking it against the array of censored words, but I've a feeling there's a neater way of doing this.

• Trivial Q about redefinition.

  - by Knowing me knowing you

  Why this isn't allowed: int a = 0; int a = 0; but this is: for (int i = 0; i < 2; ++i) { int a = 0; } As far as I know code inside for loop will be executed twice whitout actually going out of its scope, so it should also be an error to define a twice. Looking forward to your answers Thanks.

• Thousands separator in .Net/F#

  - by rwallace

  What's the recommended way to print an integer with thousands separator? Best I've come up with so far is let thousands(x:int64) = String.Format("{0:0,0}", x) Which works in most cases, but prints zero as 00.
