How can brackets be escaped in using string.Format. For example:
String val = "1,2,3"
String.Format(" foo {{0}}", val);
This example doesn't throw an exception, but outputs the string foo {0}
Is there a way to escape the brackets?

How can I show a git log output with (at least) this information:
* author
* commit date
* change
I want it compressed to one line per log entry. What's the shortest possible format for that?
(tried --format=oneline but that does not show the date)

I am trying to print an integer in JavaScript with commas as thousands separators. For example, I want to show the number 1234567 as "1,234,567". How would I go about doing this?
Here is how I am doing it:
function numberWithCommas(x) {
x = x.toString();
var pattern = /(-?\d+)(\d{3})/;
while (pattern.test(x))
x = x.replace(pattern, "$1,$2");
return x;
}
Is there a simpler or more elegant way to do it? It would be nice if it works with floats also, but that is not necessary. It does not need to be locale-specific to decide between periods and commas.

As JavaScript frameworks like jQuery make client side web applications richer and more functional, I've started to notice one problem...
How in the world do you keep this organized?
- Put all your handlers in one spot and write functions for all the events?
- Create function/classes to wrap all your functionality?
- Write like crazy and just hope it works out for the best?
- Give up and get a new career?
I mention jQuery, but it's really any JavaScript code in general. I'm finding that as lines upon lines begin to pile up, it gets harder to manage the script files or find what you are looking for. Quite possibly the biggest propblems I've found is there are so many ways to do the same thing, it's hard to know which one is the current commonly accepted best practice.
Are there any general recommendations on the best way to keep your .js files as nice and neat as the rest of your application? Or is this just a matter of IDE? Is there a better option out there?
EDIT
This question was intended to be more about code organization and not file organization. There has been some really good examples of merging files or splitting content around.
My question is: what is the current commonly accepted best practice way to organize your actual code? What is your way, or even a recommended way to interact with page elements and create reuseable code that doesn't conflict with each other?
Some people have listed namespaces which is a good idea. What are some other ways, more specifically dealing with elements on the page and keeping the code organized and neat?

I've a String representing a date.
String date_s = "2011-01-18 00:00:00.0";
I'd like to convert it to a Date and output it in YYYY-MM-DD format.
2011-01-18
How can I achieve this?
Okay, based on the answers I retrieved below, here's something I've tried:
String date_s = " 2011-01-18 00:00:00.0";
SimpleDateFormat dt = new SimpleDateFormat("yyyyy-mm-dd hh:mm:ss");
Date date = dt.parse(date_s);
SimpleDateFormat dt1 = new SimpleDateFormat("yyyyy-mm-dd");
System.out.println(dt1.format(date));
But it outputs 02011-00-1 instead of the desired 2011-01-18. What am I doing wrong?

I have a strange bug in the Visual Studio text editor.
All my blank spaces are replaced by a "."
public class Person
{
int age;
}
looks like this
public..class..Person..........................
{..................
..int age;...................
}.....................
I reset the settings to default. Didn't work.
I also re-installed VS2008. Still didn't work.
What's the error?

My blog is hosted on Blogger and I frequently post code snippets in C / C# / Java / XML etc. but I find the snippet gets "mangled".
Are there any web sites that I could use to parse the snippet beforehand and sort out the formatting, convert XML "<" to "<" etc.
There are a numbers of questions around this area on SO but I couldn't find any that address this question directly.
Edit: For @Rich answer, site states "To display the formatted code on your site, you need to get this CSS stylesheet, and add a reference to it in the <head> section of your page". That's the problem - you can't do this on Blogger AFAIK.
