Google VS the “elements of nature” or “This site may harm your computer”

Posted in Google tagged , at 4:50 pm by ilanco

While searching Google for some interesting articles to fill my Saturday afternoon, I stumbled on this. “This site may harm your computer” Google claims falsely. Seems Google doesn’t like nature, or at least it’s elements. In some further searches I noticed that it’s not only nature Google is after.

Looks more like a test/coding error, every web page on the internet is harmful.

Go Google!

wp-o-matic quick & dirty duplicate post fix

Posted in Open Source, wordpress tagged , , , , , , at 12:23 am by ilanco

I’m getting a lot of duplicate posts using wp-o-matic and if you are reading this, you probably have the same problem.

Instead of fixing wp-o-matic (that’s the developer’s job) I just changed my local wordpress to ignore posts with the same title.

Here is how it works :

  1. Open up wp-includes/post.php in your favorite editor
  2. at approx line 703 you will find the following line :
    if ($post_name_check || in_array($post_name, $wp_rewrite->feeds) ) {
  3. After this insert a new line of code :
    return 0;
  4. save (you did make a backup, right?).
  5. All done.

wp-o-matic cron install problem

Posted in Linux, Open Source, wordpress tagged , , , , , , at 2:57 am by ilanco

WP-o-Matic is a cool auto-blogging plugin for wordpress.

After installation you’ll have to change cron.php if you want to use automatic feed fetching via crontab.

  1. take note of the code wp-o-matic will give you on installation.
  2. open cron.php in your favorite editor
  3. add this piece of code after the <?php opening tag :
    if ($argc > 0)
    for ($i=1;$i < $argc;$i++)
    $_REQUEST = array_merge($_REQUEST, $tmp);
  4. fire up crontab -e and add something like the following line to it :
    */20 * * * * php /DIR_TO_WP/wp-content/plugins/wp-o-matic/cron.php code=YOURCODE
    change DIR_TO_WP with you path to wordpress and YOURCODE with the code you noted in step 1
  5. Save the file and cron will run your fetcher every 20 minutes.
  6. You’re done, go add some rss feeds.

Postgresql lc_collate aggravation

Posted in Linux, Open Source tagged , , , , , at 11:14 pm by ilanco

Implementing tearch2 on an existing postgres database : not as simple as it seems.

When trying to install tsearch2 into an existing database I stumbled upon a problem. It seems that tsearch2 takes its default locale from the lc_collate setting of the postgres cluster.

In my setup this was set to “en_US.ISO-8859-1”.

You can check your collation by sending this query to postgres :
show lc_collate;

This database was upgraded to 8.2 from an older version and the collation was set a long time ago when the database was created. Because of this setting tsearch2 refused to accept any characters outside this encoding, which was very annoying since we have our data utf-8 encoded.

The only solution was to create a new cluster with a UTF-8 collation and import all the data.

I hope postgres will support more dynamic collation settings in the future.

Download Hebrew X fonts

Posted in Linux, Open Source tagged , , , , at 1:50 am by ilanco

To install Hebrew fonts for use in X (KDE, GNOME), follow the instructions below.

You can either download a free TTF font or install available fonts if you use Debian (or a Debian derived distribution).

A free TTF font that includes support for Hebrew glyphs.

If you are using Debian or Ubuntu however you can just try this command in a shell:

sudo apt-get install culmus xfonts-efont-unicode xfonts-efont-unicode-ib xfonts-intl-european msttcorefonts

Swatch multiple log files

Posted in Linux, Open Source tagged , , , , at 12:33 am by ilanco

To make swatch parse multiple log files at once from a central syslog server use the following command from any bash compatible shell:
swatch -c ~/.swatchrc --tail-args '-q -f -n 0' -t "`find . -name *.20080104 | xargs`"

Of course you can substitute ~/.swatchrc with your own swatch config and *.20080103 with your own search criteria.

Good luck.
