Does Java have any functionality to generate random characters or strings? Or must one simply pick a random integer and convert that integer's ascii code to a character?
I'm currently trying to get into the Java EE development with the Spring framework. As I'm new to Spring, it is hard to imaging how a good running project should start off.
Do you have any best practices, tipps or major DO NOTs for a starter? How did you start with Spring - big project or small tutorial-like applications? Which technology did you use right away: AOP, complex Hibernate...
I have 4 reasonably complex r scripts that are used to manipulate csv and xml files. These were created by another department where they work exclusively in r.
My understanding is that while r is very fast when dealing with data, it's not really optimised for file manipulation. Can I expect to get significant speed increases by converting these scripts to python? Or is this something of a waste of time?
Hi,
I am drawing strings in a rectangular frame. The string is drawing perfectly. Now I need to write test cases using sentesting kit. I have no ideas from where I should start. For help I have also seen the iPhone sample calculator application
But still out of sorts.
Any body having ideas please help.
Thanks,

I am trying to debug my GWT application in IE but the page does not load. It works fine in Firefox and Chrome. In IE the browser keeps hanging. If you debug a extremely simple page it works in IE. But complex pages do not open up in IE. Can someone help me out.
Thankyou
I've got a mysql dataset that contains 86 million rows.
I need to have a relatively fast search through this data.
The data I'll be searching through is all strings.
I also need to do partial matches.
Now, if I have 'foobar' and search for '%oob%' I know it'll be really slow - it has to look at every row to see if there is a match.
What methods can be used to speed queries like this up?

How can I write a regex to match strings following these rules?
1 letter followed by 4 letters or numbers, then
5 letters or numbers, then
3 letters or numbers followed by a number and one of the following signs: ! & @ ?
I need to allow input as a 15-character string or as 3 groups of 5 chars separated by one space.
I'm implementing this in JavaScript.
A question I got on my last interview:
Design a function f, such that:
f(f(n)) == -n
Where n is a 32 bit signed integer; you can't use complex numbers arithmetic.
If you can't design such a function for the whole range of numbers, design it for the largest range possible.
Any ideas?
Hi,
I need my application to be considered localized in order for MFMailComposer to present its fields in localized language. I don't need to localize any strings or xibs. What is the minimum I need to do in order for my application to be considered localized?
TIA
I am using following directives in my htaccess to remove trailing slashs from my uris to prevent duplicate content. However these directives also remove any query string, that might be present.
RewriteCond %{HTTP_HOST} ^(www.)?mydomain\com$ [NC]
RewriteRule ^(.+)/$ http://www.mydomain.com/$1 [R=301,L]
I'd like to know how to remove a potential trailing slash from my URI, but also preserve query strings.
I have a long string in javascript like
var string = 'abc234832748374asdf7943278934haskhjdasfhjkdfas83421def8923487234897234897';
I am trying to match like
abc234832748374 and def8923487234897 - that is - I have tried like
string.match(\abc[^abc]|\def[^def]|) but that doesnt get me both strings because I need numbers after them ?
Basically I need abc + 8 chars after and def the 8-11 chars after ? How can I do this ?
I have a Word document which is several hundred pages long.
I would like to use a macro to automatically create about a dozen or so sub-documents based on certain rules (mainly, occurrence of certain strings in each Section).
Is this possible? What VBA functions should I read-up on? Does anybody know of any code examples which are even remotely similar and which I may be able to customize for my purposes?
Thanks
I have 3 separate strings:
$d = 'Created on November 25, 2009';
$v = 'Viewed 17,603 times';
$h = '389 hits';
Which needs to be converted to:
$d1 = {unix timestamp of November 25, 2009};
$v1 = "17603"; (commas stripped if it exists)
$h1 = "389";
What is the most efficient way to do this (possibly with regex)? Any code snippet would be great.
What is the difference between the following declarations:
int* arr1[8];
int (*arr2)[8];
int *(arr3[8]);
What is the general rule for understanding more complex declarations?
I wanted to display a long list of strings from an array.
Right now, my script run through a for loop echoing each value to the standard output:
for value in ${values[@]}
do
echo $value
done
Yeah, that's pretty ugly! And the one column listing is pretty long too...
I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C).
I am producing a javascript-based widget. Nothing complex just a few document.writes...
When I place it inline in the page it renders fine in all browsers. When I place it externally and load it via it fails to render in Firefox and IE but not Chrome.
Anyone know why and a possible workaround?
Is there a technical limitation of what kind of programs I can write with assembler (NASM)?
For now I've only seem some program that do arithmetic operations, like adding two numbers.
Is it possible to write complex assembler programs, that provide a GUI, access the file system, plays sounds et cetera?
I know I wouldn't write such programs, but I'm curious, if there are technical limitations on what kind of programs I can write with assembler.
Hi All,
I am trying to compare to textbox values on an aspx form. Both the values represent dates. The are formatted like "dd/MMM/yyyy". How can I compare them in javascript to see if they are not equal and which one is greater etc... Does javascript have a date constructor for strings like this? Any tips would be appreciated. Thanks for the help.
Cheers,

I'm having some issues trying to change the look / style of a combo box in Expression Blend / WPF. While there are tutorials out there describing setting styles for buttons, there seem to be a few wrinkles with ComboBox controls.
Can anyone offer any advice, or point me towards good tutorials that cover re-styling something more complex than a button?
I am new to Silverlight. How would I go about creating a control for users to tag content.
I would like it to work like it does it StackOverflow i.e. Autocomplete and when you press space it inserts the tag in a box with a remove button. I want the control to be bindable to a collection of strings.
If someone can just point me in the right direction to get me started I would be very grateful.
Which language would you propose for solving a system with:
first order differential equations
complex variables
N-dimensions
using 4th order Runge Kutta or the like.
Speed matters a lot but would sacrifice for:
Elegant (clean and short) code
Flexibility + scalability
I'm mostly between a Lisp and OCaml but any other suggestion is welcomed.
Thanks!
i've got an mvc project written in C#. i'm trying to reference it from ironpython. i've got no issue importing the objects and referencing the dll, but some of the objects rely on connection strings from the web.config, is there any way for me to reference the dll and then specify the web.config it should be using?
I have a class with 2 strings and 1 double (amount).
class Donator
string name
string comment
double amount
Now I have a Array of Donators filled.
How I can sort by Amount?
My app is a very complex game that uses json objects to store its execution state (aka save games). I'm looking for a nice database script that can talk json and interact with javascript via ajax.
