Firefox 4 lets you report when something makes you happy or sad. It's a very cute idea (although looking at the actual submissions can also make you quite sad). I wondered how long it would take until I had to use it, but here it is:

You couldn't store a bookmark without a name in previous Firefox versions, but you could delete it afterwards. After that you would only see the favicon of the bookmark on your toolbar, which saves LOTS of space.
However, someone must have thought that this was unwanted behaviour and decided to display the URL if there is no name. Messing up my toolbar

Yes, you can still use a simple space in the name field, but that still makes your icon 50% longer than it should be.

For an entire week I've been working on a canvas/html5 project of mine: the Kiflea Engine.

"What's that?", you ask?

It stands for "Kipdola's Flat Earth" Engine. It's a tiled based engine on which you can build a game. Or at least: that's the goal of the project. I'm not there yet, even though I feel like I've already made huge advancements.

The maps are built using Tiled. Any tileset you load in there will load in the engine. The HUD is built using a simple JSON file, ... As you can see in the image above, I've just finished my pathfinding algorithm.

If you want to try the engine in its current state out, you can do so here.

I would really apreciate any feedback, ideas, code optimization (did I tell you this is my first ever JavaScript program?), patches, ... Don't ask my why you can't kill anything, though. It's an engine, not a game (yet).

An awesome little cartoon on us evil, evil flappychaps. Which is my new favorite word, by the way.

On the main page ofour Kipdola site is a flash video just under the menu.
When a menu expands, it unfortunately hides behind the flash file. That's incredibly annoying.

I searched for a few fixes. Some suggested to adjust the z-index of the menu, but that still did not work. At least not in Firefox.
And then I found out you actually have to add a few parameters to the object itself.
These, to be precise:

    <param name="wmode" value="transparent" />

This goes in the <object> element. For it to work on both Firefox and IE you have to add another one to the <embed> element. Like this:

<embed src="http://some.url/flash.swf" wmode="transparent">

So the video in the showcase section on our frontpage has this code:

<object width="400" height="225">
    <param name="wmode" value="transparent" />
    <param name="allowfullscreen" value="true" />
    <param name="allowscriptaccess" value="always" />
    <param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=11104140&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=00ADEF&fullscreen=1"  />
    <embed src="http://vimeo.com/moogaloop.swf?clip_id=11104140&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=00ADEF&fullscreen=1"
        type="application/x-shockwave-flash"
        allowfullscreen="true"
        allowscriptaccess="always"
        width="400"
        height="225"
        wmode="transparent">
    </embed>
</object>

It also does what it says: makes the flash object transparent. Vimeo, for example, shows a little animation while loading the video. With transparency turned on this isn't drawn on a black background, but directly on your page. Which is pretty

Have you ever had a bunch of subdirectories each filled with only one zip file? Or have you ever had a task that needed to be done in the same way?
Well here's a handy little line of code that will help you on your way!

find -name '*.zip' | xargs -n1 echo unzip

This doesn't actually do anything yet, it searches for .zip files in every subdirectory relative to the one you're currently in and then echoes what it'll do to those files once you remove the `echo` command
So actually typing:

find -name '*.zip' | xargs -n1 unzip

Will perform the command. Another example, if you want to copy lots of files from the subdirectory of one map to another, you can do this:

find /home/user/map/ -name "*.txt" | xargs -i cp -v {} .

This will copy every .txt file under any directory, starting from /home/user/map/, to your current directory. (No matter where you are)

I love it, and it has saved me lots of time!
