x86-64 long double precision
- by aaa
hello.
What is the actual precision of long double on Intel 64-bit platforms?
is it 80 bits padded to 128 or actual 128 bit?
if former, besides going gmp, is there another option to achieve true 128 precision?

Improve long mysql query
- by John Adawan
I have a php mysql query like this $query = "SELECT * FROM articles FORCE INDEX (articleindex) WHERE category='$thiscat' and did>'$thisdid' and mid!='$thismid' and status='1' and group='$thisgroup' and pid>'$thispid' LIMIT 10"; As optimization, I've indexed all the parameters in articleindex and I use force index to force mysql to use the index, supposedly for faster processing. But it seems that this query is still quite slow and it's causing a jam and maxing out the max mysql connection limit. Let's discuss how we can improve on such long query.Read the article
