“That was pretty impressive, wasn’t it? I got the sucker.”

The original footage can be seen at BBC. Here is a great remix of this video.

Seems Navigon, one of their competitors spent a little less time on marketing and more time on development and is already able to deliver their Mobile Navigator for iPhone via the app Store.

Their Europe version sells for 99.99 Euro and comes with maps for 40 European countries.

Let’s see what TomTom will have to offer and when.

This seems to be a good replacement for the Guarana tea I am currently consuming.

Maté contains xanthines, which are alkaloids in the same family as caffeine, theophylline, and theobromine, well-known stimulants also found in coffee and chocolate. Maté also contains elements such as potassium, magnesium and manganese. Caffeine content varies between 0.3% and 1.7% of dry weight (compare this to 2.5–4.5% for tea leaves, and 1.5% for ground coffee).

I would be happy for any kind of feedback.

Here is a little workaround that was simple but good enough to provide the necessary information. It might not work on windows systems though.Also you should be aware that it will never give you the same results as memory_get_usage(), but it is working well to spot where your memory consumption grows and helps to find leaks.

<?php

if ( ! function_exists( 'memory_get_usage' ) ) {

    function memory_get_usage( $ps_opt="u" ) {
        global $pid;

        $ps=shell_exec("ps ".$ps_opt."p ".$pid);
        $ps=explode("\n", $ps);
        if(count($ps)<2){
            return false;
        }

        $ps=explode(" ", ereg_replace(" +", " ", trim($ps[1])));

        return (int) $ps[4];
    }

}

$pid = getmypid();

if ( $pid )
    printf( "mem: %d\n", memory_get_usage() );

for ( $i=0; $i<=10000; $i++ ) {
    if ( $i % 1000 == 0 )
        printf( "mem: %d\n", memory_get_usage() );
    $memeater[] = $i*$i;
}
?>

The important part is in line 3-21.
In line 3-19 a workaround function for memory_get_usage() that uses the “ps” command is defined.
The process id of the currently running PHP process is determined in line 21 and stored within a global variable.
Lines 23++ are just to show an example usage for this code.

Once again – this function is not made to determine any exact memory consumption values or replace memory_get_usage(). It is just a workaround, I use here and there to spot memory leaks in PHP scripts.

sed 's/http/\^http/g' FILENAME | tr -s "^" "\n" | grep http| sed 's/[\ |\\\|\"].*//g' | sed "s/['].*//g" | sort | uniq

And as my final goal was to extract a list of domain names from the file which I can later use in my php script here is the hardcore version which gives you a copy&paste array definition of all domains found in a file.

echo -n '$domains = array ( "' ; sed 's/http/\^http/g' FILENAME | tr -s "^" "\n" | grep http| sed 's/[\ |\\\|\"].*//g' | sed "s/['].*//g" | sort | uniq | awk 'BEGIN{FS="/"}{print $3}' | cut -d . -f 2- | grep -E '^[a-z]+\.[a-z]+$' | sort | uniq | tr "\n" "," | sed "s/,/\", \"/ig" | sed 's/, \"$//ig'; echo -n ' );'

cat original.txt | sed '/^TAGS/s/ /,/ig' | sed '/^TAGS/s/"//ig' > converted1.txt ;let lines=`cat converted1.txt|wc -l`; let lines=`expr "$lines" : '\([0-9]*\)'`; for i in `seq 1 $lines`; do line=`head -n $i converted1.txt | tail -n 1`; istag=`echo $line|grep -E "^TAGS:"|wc -c`; if [ "$istag" -gt 0 ]; then tags=`echo $line|sed 's/TAGS: \\(.*\\)/\\1/g'`; echo $tags; fi; iskeyword=`echo $line|grep -E "^KEYWORDS:"|wc -c`; if [ "$iskeyword" -gt 0 ]; then let tagline=($i+1); fi; if [ "$i" == "$tagline" ]; then echo $tags; tags=""; tagline=0; else echo $line; fi; done > converted.txt

In general you would just check out the revision you need or run a svn diff.

Sadly this is not only possible and you need to figure out the changed files which you need to copy to the server.

This simple little command creates a tar archive with the changed files.

Note: you should be in the path of the checked out repository.

let revision_start=196; let revision_end=225; tar cfv ../r$revision_start-$revision_end.tar `svn diff -r $revision_start:$revision_end . | grep Index | awk '{print \$2}'`

Luckily there is the custom css upgrade which allows an easy alteration of the stylesheet of the supported themes. Together with the sandbox theme this still gives you a lot of opportunities to alter your design and get some additional themes running on your wordpress.com blog.

For my blog here I have choosen Sandpress, a winner of the Sandbox Designs Competition

Getting such a theme to run in a wordpress.com blog is quite simple although it takes a little more effort than on a wordpress.org blog.

• First off you need to pick and download a theme and unpack it on your local machine.
• Next thing you should do is to make sure that all the image files are in one directory. So if the theme you have choosen has multiple folders for images, take all these images and put them in one folder.
• Now you need to upload these images to your blog as described in the  FAQ
  
• Then go to your media manager (/wp-admin/upload.php) and check for the url of your images (right mouse button and copy link location on one of the thumbnails should do the job).
• The urls should have something like this structure http://BLOGNAME.files.wordpress.com/YEAR/MONTH/FILENAME for example http://snipplr.files.wordpress.com/2008/10/sandpress.png
• Now we need to alter the stylesheet of the sandbox theme of our choice to fit the new urls. So we just need to open it with a text editor and make sure all the paths for url() items within the stylesheet are matching the new image urls. Usually main work will be done with a simple search and replace of “images/” with “/files/YEAR/MONTH/”
• Now it’s time to activate the Sandbox-10 theme (this should be at /wp-admin/themes.php?pa=4 on your blog)
• Once this is done we are ready to try the altered css file. No need to purchase the css upgrade right away, you can just go to /wp-admin/themes.php?page=editcss on your blog and paste the css file into the textarea. Select the “Start from scratch and just use this” option and hit “preview”.
• If everything looks like expected you just need to purchase the “custom css upgrade” and you will be able to save the stylesheet and store it for your site.

I hope this is of any use for the one or the other blogger out there. It should be simple enough to get a lot of extra themes running and if you need any help just leave me a comment.
