• CodeIgniter - accessing $config variable in view

  - by PHP thinker

  Pretty often I need to access config variables in views. I know I can pass them from controller to load-view(). But it seems excessive to do it explicitly. Is there some way or trick to access $config variable from CI views without disturbing controllers with spare code?

• Problems with usually short solutions to test in a programming language

  - by sub

  I'm currently creating an experimental programming language for fun and educational purpose and in search for some tasks beyond the classical "Hello, World!"-program. I've already come up with these ideas: Print out the program's input Calculator Generate Prime numbers, Fibonacci series What other interesting programming problems do you have for me to test? It would be good if they required the language to solve a broad spectrum of task, take prime numbers for example: You need variables, increment them, divide them, perform actions under certain conditions, etc.

• Is this the best approach using generics to check for nulls

  - by user294747

  public static T IsNull<T>(object value, T defaultValue) { turn ((Object.Equals(value,null)) | (Object.Equals(value,DBNull.Value)) ? defaultValue : (T)value); } public static T IsNull<T>(object value) where T :new() { T defaultvalue = new T(); return IsNull(value, defaultvalue); } Have tested, and can use against data objects, classes and variables. Just want to know if there is better way to go about this.

• When knowledge of "multithreading" is specified in a C++ job description, what is the expectation?

  - by Vaibhav Khattri

  I understand it should cover threading primitives (mutex, semaphore, condition variables etc.) plus design patterns (such as those specified in POSA2). But what's more? Every project has its own multithreading scenarios and one may have not dealt with those that the job is expecting?. So how does one build their knowledge and prove that they have the ability?

• Best way to initialise / clear a string variable cocoa

  - by Spider-Paddy

  I have a routine that parses text via a loop. At the end of each record I need to clear my string variables but I read that someString = @"" actually just points to a new string & causes a memory leak. What is the best way to handle this? Should I rather use mutable string vars and use setString:@"" between iterations?

• Using CompareTo() on different .NET types (e.g. int vs. double)

  - by Yossin

  Hi, I've got a static method that accepts two object type variables and runs the CompareTo() method: public static int Compare(Object objA, Object objB) { return (((IComparable)objA).CompareTo(objB)); } Problem is that CompareTo() throws an exception when trying to compare between different types (e.g. int and double). Does any one know of a better way in C#, to compare between two different types? Or a workaround to this problem? Thanks

• Is there something similar to jEval for C# / .net ?

  - by Calvin

  I'm looking for a language that will parse mathematical expressions for me pretty easily, but also be able to call functions and reference variables as needed. Jeval looks to be what I'm looking for, but unfortunately I'm working in C#. Is there a .Net based equivalent to jeval?

• How do I conditionally redirect the output of a command to /dev/null?

  - by Lawrence Johnston

  I have a script. I would like to give this script a quiet mode and a verbose mode. This is the equivalent of: if $verbose then redirect="> /dev/null" fi echo "Verbose mode enabled" $redirect # This doesn't work because the redirect isn't evaluated. I'd really like a better way of doing this than writing if-elses for every statement affected. eval could work, but has obvious side effects on other variables.

• [python] parsing a string based on specified identifiers

  - by jml

  Let's say that I have the following text: in = "one aaa two bbbb three cccc" I would like to parse this into a group of variables that contain notworking = ["one", "two", "three"] v1,v2,v3 = in.split(notworking) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml
