.jm to be no longer free.

The Mona Information Technology Services (MITS) Department of the University of West Indies (UWI) has decided to charge for .jm domains.

I am happy for this so long as it results in better service, including quicker turnaround time. However I find this statement in the article puzzling.

"The charge for .jm would remain competitive with international rates, as low as US$35 ($2,310) per year, said Samuels."

Internationally the highest rates are US$35 per year in most jurisdictions while costs can be as low as US$2 per year, if not less.

I would like some clarification on this.

There is another statement that is also interesting, although I am not sure they can actually do it what it says. The actual statement of interest is "analysing 'hits' to a given website". The full statement is below.

"Besides registering and administering all .jm domain names, MITS also conducts website research including domain name searches and analysing 'hits' to a given website."

Again clarification on this would be good. Privacy invasion.

Minimum Character length and MySQL Full Text

Every now and then you come across some nusiance

Mysql Full Text search is lovely but it has some weaknesses. One of which is its Minimum Character length requiremnet.

Happily, the fix is fairly easy if you have access to the .cnf file

Changing the Minimum Character length

1. check what .ini/.cnf your mysql is reading
2. change your my.ini/.cnf like this:
[mysqld]
ft_min_word_len=3
ft_stopword_file="C:\\MySQL\\stop.txt"
3. restart your mysqld
4. reindex your table using REPAIR TABLE tbl_name QUICK;
