• What is the best method to convert to an Integer in JavaScript?

  - by Mathew Byrne

  There are several different methods for converting floating point numbers to Integers in JavaScript.

Here are a few methods that I know of: var a = 2.5; window.parseInt(a); // 2 Math.floor(a); // 2 a | 0; // 2 I'm sure there are others out there. Suggestions?

• effective functional sort

  - by sreservoir

  I'm programming a function for a TI-NSpire, so I can't use the builtins from inside a function. What is the most generally efficient algorithm for sorting a list of numbers without modifying the list itself? (recursion and list-splitting are fair game, as is general use of math.)

How can I do the same in Python? I read a bit but got confused with tuples and similar things If you could point me to a similar example it would be great thanks

• Best FTP wrapper for iPhone

  - by jamone

  I know you use the C based networking API to do FTP communication but I'd prefer to use something a little higher level. I've seen a few Objective-C based wrappers but I'm not sure what to use. I don't need that complex of FTP interaction. Its just the typical create/delete dirs, upload/download files... What do you recommend?

• Any special assertion to test if the resulting integer lies within a range

  - by barerd

  I would like to test if an instance variable lies in a range of numbers. I solved the problem by using assert_in_delta but would like to know if there is a formal assertion for this. #part of the tested class def initialize(value = 70 + rand(30)) @value = value end #test_value.rb class ValueTestCase < Test::Unit::TestCase def test_if_value_in_range assert_in_delta(85, p.value, 15) end end

• How can i interpret a time value in ascii into a numerical value?

  - by Bilal

  I have a file which is as follows: 15:03:21 II 0.88 0.64 15:03:31 II 0.88 0.64 15:03:42 II 0.40 0.40 etc. after loading the file in matlab, I want to be able to read the first column (which corresponds to time) and interpret them as numerical values. At the moment, they are interpreted as a string of ascii characters and i can't perform any mathematical operations on them. Does anyone have any suggestions as to how i can read the time as numbers instead of a string of ascii characters?

• Django: FloatField or DecimalFied for Currency ?

  - by Hellnar

  I am curious which one would be better fitting as a currency field ? I will do simple operations such as taking difference, the percentage between old and new prices. I plan to keep two digits after the zero (ie 10.50) and majority of the time if these digits are zero, I will be hiding these numbers and display it as "10"

• What is the current state of the art in HTML canvas JavaScript libraries and frameworks?

In particular, are there frameworks that support the kind of things needed for game development - complex animation, managing scene graphs, handling events and user interactions? Also willing to consider both commercial and open source products.

• What are the differences between these?

  - by Amit Ranjan

  What are the differences between the two queries? SELECT CountryMaster.Id FROM Districts INNER JOIN CountryMaster ON Districts.CountryId = CountryMaster.Id SELECT CountryMaster.Id FROM CountryMaster INNER JOIN Districts ON Districts.CountryId = CountryMaster.Id Please mind the i) Table positions and second ii) On Fields As I know, output will be same. But I want to know, is there any drastic effects of the same if I neglect positions of tables and columns in complex queries or tables having tons of data like thousands and lakhs of rows...

• Is there a way to do gsp partials rather than tag libraries?

  - by egervari

  One of the things I liked about freemarker is that you can quickly create new macros that encapsulate complex html to make the pages smaller and more concise. Do I have to make tag libraries to do the same thing in grails, or is there a really light-weight syntax for achieving the same thing?

• How does a cryptographically secure random number generator work?

  - by Byron Whitlock

  I understand how standard random number generators work. But when working with crytpography, the random numbers really have to be random. I know there are instruments that read cosmic white noise to help generate secure hashes, but your standard PC doesn't have this. How does a cryptographically secure random number generator get its values with no repeatable patterns?

Why is that so and how can i fix this?

• Graphviz for documentation.

  - by Marcin

  I noticed that doxygen uses the graphviz library for creating diagrams. Have you ever used graphviz for generating documentation? Is it worth learning the graphviz for documentation purposes outside the scope of doxygen? Or am I better off to sticking with a standard data modeling package like Visio? I understand the merits of it as a graphing library, but for trying to represent more complex UML (or similar) is it still worth looking into?

• Extend precision of MySQL's double datatype?

  - by tim82

  I am trying to save the value "6.714285714285714" into a DOUBLE datatype field. Unfortunately it does not fit at all and is cutted by one char. Storing larger numbers becomes less precise. Already searched in the mysql manual and it seems to be that double is the most precise data type available. Anyone knows a practicable workaround? Sorry for my bad english and thx a lot!

• Creating a unique URL safe hash

  - by Ben Foster

  I want to hash/encode a unique integer (database ID) to create a similarly unique string. It needs to meet the following requirements: Must start with a letter or number, and can contain only letters and numbers. All letters in a container name must be lowercase. Must be from 3 through 63 characters long (although the shorter the better) The result does not need to be reversible, just repeatable - so a 1-way hash would be fine.

• How do I create a ListBox In Ext-GWT ?

  - by Salvin Francis

  Plain and Simple, I want to use a Listbox in my project, The demo here: http://www.extjs.com/examples shows no answer, In fact, I really hate it when companies show-off their 'complex' widgets in this manner and fail to show the most basic of all widgets. For example, I discovered class SimpleComboBox over the net till then I assumed that we required a class to contain list store, etc...
