Misc: Forward and Back Slashes

Just a reminder not to get confused.

This is a slash: /. Because the top of it leans forward, it is sometimes called a “forward slash.”

This is a backslash: \. Notice the way it leans back, distinguishing it from the regular slash.

Slashes are often used to indicate directories and subdirectories in computer systems such as Unix and in World Wide Web addresses. Unfortunately, many people, assuming “backslash” is some sort of technical term for the regular slash, use the term incorrectly, which risks confusing those who know enough to distinguish between the two but not enough to realize that Web addresses rarely contain backslashes.

.NET: Ignoring Thread Abort Exception in Enterprise Library Exception Handling

Noticed that the trace.log in TRAKIT was filling up rather quickly.
Whenever it hits a response.redirect, .NET was generating a thread abort exception.

To ignore, do this:

try{
//your try block
}catch(System.Threading.ThreadAbortException ex)
//exception ignored to prevent logging in trace.log
}catch(Exception ex){
//catch error using Enterpise Library logging
bool rethrow = ExceptionPolicy.HandleException(ex, "Business Layer Policy");
if (rethrow){
//throwing the error again to write to page
throw;
}finally{
//Do something
}

MSSQL: Truncate large Transaction Log files

Needed to truncate log files on prod server, found this nice tsql code snippet to handle this task.

/**SHRINK TRANSACTION LOGS**/
/**RUN EACH STEP SEPARATELY **/

--STEP 1 - Select database & get its logical name
USE [drd-data];
SELECT * FROM sysfiles;

--STEP 2 - From result window input file name to shrinkfile command
BACKUP LOG [drd-data] WITH TRUNCATE_ONLY
DBCC
SHRINKFILE('drd-data_log', 95);

Ajax: Caching Problem with Requests

http://radio.javaranch.com/pascarello/2005/10/21/1129908221072.html

"The question: The Ajax request is grabbing the cached page from the previous request, how do I stop this from happening?
Well I have seen some fancy approaches by people, but there is one easy solution that works: a random query string value appended to the request.

So how and why does this work. Well it simple terms, when the browser looks at the destination, if it has a match, then it uses the data it has. Now this is great for when you are going to a static website, but since we are looking for new data, it sucks. By appending a random value to our parameters that we are sending back, it forces the browser to say, "Stop the press! We got new info here! Lets go get the data!"

"... a simple "+Date()" appended to the request URL and viola!"

OR

"Hey guys, just wanted to add a way to ad this random string to the URL. When passing the url you can append the random function Math.random(); to the url string like this: var urlVar = urlVar + '&' + Math.random();"

OR

"A much more elegant solution would be to use the following code:

xmlhttp.open("GET", theURL ,true);
xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
xmlhttp.send();

The second line of the code instructs the XMLHttp object to avoid
caching content that has been modified after the mentioned date.
It worked fine for me..."

Google code search

Google code search supports POSIX extended regex syntax.

http://www.google.com.au/codesearch?hl=en

Some advance search examples:

The lang: operator, which restricts by programming language (e.g., lang:"c++", -lang:java, or lang:^(c|c#|c\+\+)$)
The license: operator, which restricts by software license (e.g., license:apache, -license:gpl, or license:bsd|mit)
The package: operator, which restricts by package URL (e.g., package:"www.kernel.org" or package:\.tgz$)
The file: operator, which restricts by filename (e.g., file:include/linux/$ or -file:\.cc$)

Google Search Tricks from Tom's Guide

Get firefox extension, Customize Google
Surround keywords with quotes
Use at least 3 keywords
Use the * wild card
Limit search by using minus (-) character. Chewy -food, returns chewy but not food
Specific filetypes, chewy filetype:pdf
Specify number of results, &num=5 in result querystring
Brackets, (“www.tomguide.com and AMD” or “Pentium*”)
Limit search to a website, site:www.tomsguide.com firefox
Remove spam filters by adding this to querystring, &filter=0
Synonyms (doesn't seem to work), ~vicarious
Spelling Options, Penryn|Penrin
Google Calculator, 100 m to ft
Word Definition, define:isotope
Currency Conversion, 50 dollars in euros
Language Translation
Google preferences, link is located right side of search bar
Google News
World News
Finding the right image size, in google images click on the "all image sizes" box, below the search bar.
Images search setting, filter based on format, colors, size
