• Interesting task using random numbers only

  - by psihodelia

  Given any number of the random real numbers from the interval [0,1] is there exist any method to construct a floating point number with zero decimal part? Your algorithm can use only random() function calls and no variables or constants. No constants and variables are allowed, no type casting is allowed. You can use for/while, if/else or any other programming language operands.

• Java weird generic return type

  - by drozzy

  Browsing through Guava libraries I saw this weird signature on a readLines method from Files class: public static <T> T readLines(File file, Charset charset, LineProcessor<T> callback) I know a little bit about generics in java, but this baffled me. What does the double T mean here? And why is the first one in angled brackets?

How would i go about creating such functionality? Greetz, Richard

• How to check the type of a Parameter in an Expression Tree (similar to 'is' keyword)

  - by Callum Rogers

  How do I check the type of a Parameter in an Expression Tree (and get the Expression Tree equivalent of a bool if it the right type)? If it were normal code, I would do this: if(myObj is int) I see there is a Expression.Convert method but this converts the object instead of just checking its type. EDIT: I found the answer, you use a Expression.TypeIs

What causes this? Also, is it possible to add .pdb files to a project's references? Thanks

• How do I update a cumulative field in a Rails database (using ActiveRecord or Mongoid)?

  - by picardo

  I want to update a field in a database table that has to have a cumulative value. So basically I need to find the current value of the field and update it using a new number. My first inefficient try at this (in Mongoid) is: v = Landlord.where(:name=>"Lorem") v.update_attributes(:violations=>v.violations + 10) Is there a simple method than making one query to read, then sum up, and another query to write?

• Ruby (and Rails) nested module syntax

  - by brad

  I'm wondering what the difference is between the following two modules # First Example module Parent module Child end end and # Second Example module Parent::Child end Using the 2nd method, it appears as though the Parent module must be previously defined, otherwise I get an 'uninitialized constant' error Given this, what is the preferred way of defining modules such as this and then adding nested children with regards to syntax and file structure (ie. folders etc). Reference to a Rails way would be greatly appreciated. Are these two examples for all intents and purposes equivalent?

• How to make a macro which gives back a string into the source code?

  - by mystify

  Example: I want to do this: METHODNAME(5) { // do something } which results in: - (void)animationStep5 { // do something } Is there any way to do this? Basically, what I need is a way to generate a real source code string before the program is compiled, so the compiler does see - (void)animationStep5... Or maybe there's something different than a macro, which can help here to auto-generate method names (not at run-time)?

• How to signal object instantiation in a Collaboration/Communication Diagram?

  - by devoured elysium

  I'd like to know how to translate the following line of code to a Collaboration Diagram: Food food = new Food("abc", 123); I know that I can call an Food's method using the following notation: MyStaticMethod() ----------------------> -------- | | | Food | | | -------- being that equivalent to Taste taste = Food.MyStaticMethod(); and MyInstanceMethod() ----------------------> --------------- | | | food : Food | | | --------------- is equivalent to food.MyInstanceMethod(); but how do I signal that I want to call a given constructor on Food? Thanks

• Is there a better way to share master pages now that VS 2010 and .Net 4 are out?

  - by Max Schmeling

  I'm trying to find a better way to share a master page than the old method of using Web Deployment Projects and a really nasty master page to share master pages between applications. I would think Microsoft would have given us something a little nicer in 2010, but I haven't found anything. Any ideas?

• C# enum to string auto-conversion?

  - by dcompiled

  Is it possible to have the compiler automatically convert my Enum values to strings so I can avoid explicitly calling the ToString method every time. Here's an example of what I'd like to do: enum Rank { A, B, C } Rank myRank = Rank.A; string myString = Rank.A; // Error: Cannot implicitly convert type 'Rank' to 'string' string myString2 = Rank.A.ToString(); // OK: but is extra work

• Hero Class, php classes

  - by John

  I am going to have different classes for a character that a user play. Like "Mage, Warrior" etc. I am thinking of a method like have some CharacterBase class (abstract?) and then I have a child class which is like WarriorClass or something like that. I think the approach is called Factory pattern or something like that. Anyone got a clue of what I'm trying to achieve here, and are there perhaps any better way to do this?

• How to launch from Eclipse in Low priority under Windows?

  - by adum

  I'm running programs from Eclipse (on Windows) that eat a lot of CPU time. To avoid bogging down my whole machine, I set the priority to Low with the Task Manager. However, this is a cumbersome manual process. Is there a way Eclipse can set this priority automatically? EDIT: I realized that each particular launcher (Java, Python etc) has its own configuration method, so I will restrict this question to the Java domain, which is what I need most.
