Project BigResource

Since 2005, our team is working 24/7/365 to maintain one of the World's largest resource center for webmasters and programmers. The project comprises a directory of 50,000 Scripts & Tutorials relating a wide range of programming languages from PHP, .NET, ASP and Java to emerging Android & iOS development.

We also maintain an index of over 3 million questions/answers posted over internet relating aforementioned technologies. To learn more about Tracker, click here.

It took us 10 years of hard work to build an index of 3 million plus qualified Q&As by humans, not the bots. Just Crawling and building a database of messages is not an art. The success of this unique project lies in the human editing of these messages by professionals for content validity and definitive solution to various problems to stay focused on the issue & saving time. Compare and see the difference between an original post on a forum and the same edited message added to our index here. No unanswered posts, salutations, lengthy code lines, images, avatars, attachments, closing remarks, reference URLs, signatures etc., just the core issues and solutions to them.

As of June 2014 stats, 50,000 unique visitors/webmasters visit us every day to get benefited from this index. We are working hard and striving harder to provide programmers an unmatchable resource index to their unanswered questions.

Printing From Within Popup Window - Doesn't Work In IE
I create, open and populate a popup window:

function DisplayPopup (aObject) {
var win2; //popup window
win2 ='', 'Description', 'alwaysRaised=yes,width=300,height=400);


However, the link to print the content of this window (<a href="javascript:window.print()">Print</a>) doesn't work in IE (no error, no action). This code works in FF and Chrome, bringing the standard window print dialog and properly printing the popup content - exactly as desired.

what I do wrong here and how to do this right? IE is the standard browser for us and even IE-specific solution could be OK... We have IE 7 if that matters. ...

Convert String To Number In INSERT Statement
I am starting with mysql and want to convert a string like 12.567,98 (dutch format) to a number (decimal format) in an INSERT statement. I did the same with a date using str_to_date but I can't find a similar function for numbers. As far as I can see convert or cast are either not suitable in an insert statement or do not allow to specify the number format (e.g. ##.###,##). ...

Table Set Up For Sorting Articles
I'm new to SQL (so far I've read a book on it, set up a database, populated it with some data from my current flat file system and started converting areas of the website over).

I run a Perl site where the most important feature is that members can post articles. I'm thinking about how best to structure my tables for the various sorting methods for viewing articles.

However, I want to offer some additional sorting mechanisms. For example I want to be able to sort and return members (article authors profiles), instead of just articles.

So listings of members (perhaps in "last online" order, which is a column in "members" table) who post mostly to a particular category. So it's going to have to go through the "articles" table and work out which category every article is in (by category id), how many articles each member has published and which category they have posted most articles too. That seems like a lot of work and in effect is it a table scan on both the members and articles tables?!

I'm wondering if it's more economical to somehow work this out as I go along (eg. a table with each member id and a column for each possible category id and how many of each they have (added to from my perl code). However, that's essentially repeating information, which you're not supposed to do in MySQL? Plus I'd still need to compare each column in each member row of this new table to see which has the highest value.

P.S. I want to offer quite a lot of different ways of sorting articles and article authors, I assume using indices on each sorting variable is recommended? Am I right in thinking that only returning the results I need (say 1-20 for the first page, 20-40 for the second etc.) will really speeds things up, even though it still has to look at everything? (I'm used to working with large arrays in the current flat file system). ...

Avoid (Using Temporary) And (Using Filesort) With ORDER BY?
I still can't manage to get rid of "Using temporary" and "Using filesort" in a simple query. I know this is a problem of keys but I can't find the right combination...I also don't know if the order of the join defined by the optimizer is ok, I tested other orders using STRAIGHT_JOIN but nothing better... The query is pretty slow using ORDER BY, but really fast without it and of course without "Using temporary" and "Using filesort"! (there is something like 100.000 rows in points table)

The query :

FROM points,


From now I don't know what to test to try to avoid the "Using temporary" and "Using filesort"... ...
