My .screenrc

This .screenrc has a bunch of commented out lines that I don’t use, but I know if I delete them, I will need them for some reason and wish I didn’t.

# this seems to only work on certain machines

This is a very simple webapp. It displays images that iPhones and iPod Touches can use as wallpaper. There isn’t really a need for offline use with the iPhone, but the iPod Touch could benefit from it. It took me about 10 minutes to learn what to do, and implement it for full offline use. The key to making a web app work offline is to add a manifest file.

Easy way to convert video online

Ever needed to convert a video from one format to another? I needed to convert a flv to a mp4 yesterday and found that there were lots of programs out there that say they can do this. Some are free, some cost money. The first six I downloaded didn’t work at all. Then I found this:

http://onlinevideoconverter.com/

Worked like a charm. If you need to convert video from one format to another, that is the site to use.

Obscure PHP5 information

<?= $variable ?> is depreciated in PHP5 (along w/ all other tags that are not <?php ?>). I don’t care so much about the others, but I actually use this one. <?= $title ?> just makes more sense than <?php echo $title; ?>
The last instruction before a closing tag does not require a semicolon; however, this is probably a bug in the PHP parser and you should always terminate it anyway. Perhaps <?= $variable ?> should actually be <?= $variable; ?>.
use BCMath functions for precision math. This isn’t really obscure, but every now and then I run into people that have never heard of it, so it makes the list.
Referring to a variable by-reference is slower than referring to a variable by-value (&$a vs. $a)
more to come….

Small JavaScript DateTimeTools object

So I got the project working on a tv schedule at work. As you can imagine there is work that needs to be done with dates and times when moving forward / back in the schedule. I found a few things out there that were full blown date/time js libraries, but they were a bit more than what I needed and didn’t do exactly what I needed. So I threw the following together. It does have specific stuff in it that is probably not portable to other projects, but here it is.

Ever need to iterate though all the members of an object (javascript)?

You know you have… if you are like me though, you can never remember the exact syntax. Here it is:

for (var name in object)
{
    if (object.hasOwnProperty(name))
    {
        alert(name + ': ' + object[name]);
    }
}

Your HOSTNAME not staying?

Ran into this recently. Not sure if it is a new “feature” of Mac OS X 10.5.7, or just the way my new AT&T U-verse router works.

Say you happen to do a clean install of Mac OS X (or any OS really), then connect to your wireless network, then do all the system updates, then finally get around to doing your custom settings.

One of the first things I change is the host name. I prefer themed names around something cool, vs. generic names like admins-mac-mini.local.

I fired up the System Preferences, went to the Sharing preference pane and changed the Computer Name from Admin’s Mac Mini to meimi. Did a few other things, restarted, fired up terminal and got this beautiful prompt:

admins-mac-mini:~ admin$

Hrm….

Come to find out the DHCP on my network has cached the initial name of the computer and just doesn’t want to let it go. I am sure there is some way to force it to update, but here is another way.

Open up Terminal
$ sudo vim /etc/hostsconfig
make sure you have the following line: HOSTNAME="meimi.local" – change it to your hostname of choice and add .local to the end of it
