While converting my cvs repositories to git I needed to copy all the changed files from my working directory into a temp directory and then into my git working dir. This was the solution that I came up with:

cvs -qn update -d 2>/dev/null | grep '^[M|\?|P] ' | awk '{print $2}' > files.list
while read file; do cp -r -f --parents "$file" /tmp/dest/; done < files.list

Basically, cvs -qn update -d does a mock update (doesn’t change files), piped to grep to only list the changed files, use awk to exclude the M, P, ? etc, output to a file.

Loop over the lines in the new file using the cp –parents to preserve directory structure

I’m always getting grief from my managers about not testing in IE6, which is hard when IE7 is installed on all machines these days. I recently found a little install tool which allows you to run multiple versions of IE on the same machine. It doesn’t fully install IE, just the dll’s and uses dll redirection to trick windows into running an older version of IE.

Although it’s not perfect, it’s a lot easier than running a virtual PC for each version.

I found a good page which outlines which characters can be used in email addresses:

I was dissapointed when I saw the current Google sitemap generators available, so I wrote one.

Features:
– Generates Google sitemaps
– Generates Yahoo! sitemaps
– Generates plain text sitemap
– Splits sitemaps up into smaller files (as per Google’s instructions)
– Creates sitemap index file
– Pings Google/Yahoo!

This is the first release, so there’s probably some bugs in there somewhere. Please let me know if you find any. There are some examples in the zip file.

To best use the classes, set the variables on the page you call the class from, rather than editing the class file (so changes aren’t lost when you upgrade).

E.g.

[php]
$sitemap = new Google_Sitemap();
$sitemap->doPing = false;
$sitemap->gzip = false;
$sitemap->baseurl = “http://www.noodles.net.nz”;
[/php]

Version 0.2 – 14/05/2007

Fixed problem with script using too much memory when trying to sitemap hundreds of thousands of pages.

I’ve written a crude datacenter checker. Unfortunately I cannot host it for everyone as Google would ban my server’s IP, so I’ve packaged up the code so anyone can run it.

A while back I ran into a problem with PHP, how can I read in files that have double byte (unicode) characters and display them in a form that any browser can read. Most programming languages don’t handle these characters very well, and end up with non sense instead of passing through the correct text.

This function should be able to strip out any unicode characters from text and return them as html entities (something none of the core PHP functions are able to do).

[php]
function removeuni($content){
preg_match_all(“/[\x{90}-\x{3000}]/u”, $content, $matches);

foreach($matches[0] as $match){
$content = str_replace($match, mb_convert_encoding($match, “HTML-ENTITIES”,”UTF-8″), $content);
}

return $content;
}
[/php]
