От известно време си имаме на http://www.cenite.com чисто нова търсачка.
Преди беше просто досадно да се търси в сайта и макар, сайта върши работа.
Резултатите с новата търсачка са налице, вижте разликата:
- Преди за един резултат се чакаше приблизително от 2 до 4 (олеле) секунди.
- Търсеше се само в името на продукта
Сега:
- Търсенето става мигновенно – повече време отнема да се изобрази страницата от броузера :)
- Търсенето е едновременно в заглавието на продукта, както и в описанието му, като се дава превес в резултатите съдържащи ключовите думи в името на продукта.
- Може да се избира по кой полета да се търси, макар че не ми е останало време да публикувам HELP към търсачката.
- Сортиране по точност на намерите резултати.
- Отпаднаха притесненията за Иванчо ;drop table students;
Изглежда и посетителите също оценяват предимствата на новото търсене, от 1000 посетителя на ден в момента са над 2500 като всеки ден се увеличават.
I got this error when I have to upgrade one old project from rails 1.2.5 to rails 2.1 (the problem is not in rails)
ActionController::MethodNotAllowed Only get, head, post, put, and delete requests are allowed.
The exception:
ActionController::MethodNotAllowed (Only get, head, post, put, and delete requests are allowed.):
/usr/lib/ruby/gems/1.8/gems/actionpack-2.1.0/lib/action_controller/routing/recognition_optimisation.rb:65:in `recognize_path'
/usr/lib/ruby/gems/1.8/gems/actionpack-2.1.0/lib/action_controller/routing/route_set.rb:384:in `recognize'
I got this error only when I access URL’s with param like
http://127.0.0.1:3000/dod/images/show_big_image/1639
I found that the problem was in the :id because without the :id the method was called correctly
This means that there is something with the routes.
Not working routes.rb: ….
map.connect '', :controller => 'auth' # Install the default route as the lowest priority. map.connect ':controller/:action/:id' map.connect ':controller/:action/:sort_key/:sort_order'
it will work if you swap the last two lines….
map.connect '', :controller => 'auth' # Install the default route as the lowest priority. map.connect ':controller/:action/:sort_key/:sort_order' map.connect ':controller/:action/:id'
It seems that it does reading the comments in the routes.rb is usefull. There is written:
# Install the default route as the lowest priority. This error also occurs if you haven't restart your webserver. I know that there is no need to restart it but its true, try restarting and check.
Here is nice tutorial how to move your project from rails 1.2.x to 2.0
- upgrade the gems: http://wiki.rubyonrails.org/rails/pages/HowtoUpgrade
-
gem update --system

Java install
ls /usr/portage/dev-java/sun-jdk/
emerge -av =dev-java/sun-jdk-1.5.0.13
java-config -L
java-config -S 1
/usr/sbin/env-update && source /etc/profile
Emerge and Equery
Taken from here
emerge brings in new packages. equery looks at the package database.
- update repository:
- emerge –sync
- install package with query
- emrge -av sun-jdk
- start with this software
- emerge links wget htop
- emerge …
- manipulate package database
- emerge -NDtu world
- –update packages and packages that depend on updated packages (–deep) in the world list. Give output in –tree format. Consider packages changed if their USE flags have changed (–newuse, -N) Add –pretend (-p) to just see what it will do first.
- emerge –skipfirst …
- skip first pkg on a rebuild; very useful if something doesn’t work
- equery …
- query package database
- equary belongs
- who owns these files?
- equery list
- list packages on system
Maintenance
Taken from here
Do this whenever you want a steaming pile of fresh packages.
# emerge --sync
# emerge --update system
# etc-update if necessary
# emerge --update world
I have seen Meddle to do it this way
emerge –newuse –deep –update world
emerge –ask –verbose coreutils
emerge –resume
Fix the mktemp / coreutils block in Gentoo
Looks like mktemp is now provided by coreutils. No wonder. This block has been bugging me (read: I’ve been ignoring it) for months.
To fix just unmerge mktemp and update coreutils.
Update: Same for the setarch / util-linux block should you come across it. Unmerge setarch.
.clearfix
<div style=”clear: both”> – do you remember this? I hate it.
The people has found a solution for this.
http://www.positioniseverything.net/easyclearing.html
.clearfix:after {
content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
.clearfix {display: inline-block;}
/* Hides from IE-mac \*/
* html .clearfix {height: 1%;}
.clearfix {display: block;}
/* End hide from IE-mac */

PNG Patch for IE
Since IE6 doesn’t render PNG-24 properly, the following hack is required in order to display the transparent PNG (add anywhere in between the <head> tag):
<!--[if lt IE 7]>
<style>
h1 span {
background: none;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='gradient.png', sizingMethod='scale');
}
</style>
<![endif]-->

Goodbye MySQL
I was optimistic that I could make http://www.cenite.com, a price monitoring website to use the fulltext search of mysql. Unfortuntly I have found so many drawbacks that I have to leave this idea. The main source for information for me was:
http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html
http://devzone.zend.com/node/view/id/1304#Heading14
At first the speed was wonderfull. I was searching in 300k> records apx. 350mb. But then I have to surrender. I cant configure mysql to work as I want. I know that If I spend two days to become expert on C/C++ with Unicode I will success but this is not the case. I want working solution.
The resons that make me not to use mysql for searching:
There is no way to change the default operator by default it is OR. You must parse the user query and rewrite it.
I want automaticaly truncation on all my terms.
There is no way to tell MySQL what are characters, and what are not…..sorry, there are two ways:
1. Touching the sources,
2. Configuring in xmls
No documentation on both. Maybe there is …somewhere.
If you use the default configuration then you will wonder how you get or not get the required results.
Here is a summary of the comands that I use to tweak my mysql server:
SHOW VARIABLES LIKE ‘ft%’
SET @global.ft_min_word_len=2;
SET @local.ft_min_word_len=2;
But it is better to have those options in my.conf
[mysqld]
ft_min_word_len=3
ft_stopword_file=”C:\MySQL\stop.txt”
[myisamchk]
ft_min_word_len=3
ft_stopword_file=”C:\MySQL\stop.txt”
To check what characterset is using your mysql:
SHOW VARIABLES LIKE ‘character_sets_dir’;
/usr/share/mysql/charsets | E:MySQL Server 5.1sharecharsets
SHOW VARIABLES LIKE ‘characte%’
After that you need to rebuild your index with one of those commands
slow: REPAIR TABLE products QUICK;
slow: myisamchk –recover –ft_min_word_len=3 tbl_name.MYI
fastest: DROP INDEX …; CREATE INDEX….;
