Нова търсачка за цените

J June, 2008 /

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.

Only get, head, post, put, and delete requests are allowed.

J June, 2008 /

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.

Upgrading Rails

J June, 2008 /

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
  • http://macournoyer.wordpress.com/2007/10/28/moving-to-rails-20/
    • nice task to find the deprecated elements: “rake -T deprecated”, 10x!

Gentoo Cheatsheet

J June, 2008 /

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.

CSS Tricks

J June, 2008 /

.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]-->

Web Spiders and expired content

J June, 2008 /

All my spiders were taking all content from a website on a single visit starting from the begining.

It seems that the idea of remembering which urls “produce” links with content is not so very bad.

Here is what I found for diri.bg – a local Bulgarian SE.

I see that diri.bg hasn’t remove from their page

show_categories.php

Even I have no links to this page. Check the result here

Ops. Google do it the same way: here

Then how to get rid of old pages without leaving “bad” links in internet?

I will try to put show_categories.php in robots.txt to see what will happen with this page.

Search engines

Rsync for windows

  • I have tried this one. A lot of GUI it has run without any problem.
  • Next I will try this one it has an rsync server – nice…but it wants cygwin…maybe next time.
  • DeltaCopy Seems like a good match, but i cant just run the rsync that is in the zip file, you must setup some local servers etc.
  • Wonderfull blog with a lot more to read/try
