Unfortunately dealing with links and permissions is not really easily possible in java. At least with the following code you can figure out whether you dealing with a link or not. A similar piece code has recently been contributed to the commons-io project. Found that really useful and worth sharing.

public static boolean isLink( final File file ) throws IOException {
        if (file == null || !file.exists()) {
                return false;
        }

        return !file.getCanonicalFile().equals(file.getAbsoluteFile());
}

An easy way of finding out about the health of your MacBook/MacBookPro battery is to use this little command line.

$ ioreg -w0 -l | grep Capacity
"CurrentCapacity" = 5259
"LegacyBatteryInfo" = {"Capacity"=5279,"Voltage"=12596,"Flags"=7,"Current"=5259,"Amperage"=267,"Cycle Count"=48}
"DesignCapacity" = 5500
"MaxCapacity" = 5279

MaxCapacity is the current capacity your battery can still hold on a full charge. DesignCapacity was the original capacity. So if the difference gets too big your battery is probably end of life and ready to be replaced. Most likely the related Cycle Count is high then as well.

It would actually be a neat little project to collect this information over time with RRDTool. If you are OK to shell out a few bucks there already is a software called ibat that seems to do this.

Update: There is also a freeware tool called coconutbattery that shows this information in a nice UI.

Unfortunately Cocoon has always had a marketing problem. Finally there is now a screencast available showing off the class reloading (done through jci). Wish it was using a better player and be with voice. But it’s a good start – we just should have done that ages ago. At that time it wasn’t all that well integrated but something similar I’ve already presented at the Cocoon GetTogether in 2005.

I guess no one is really able to follow the rationale behind Apple’s iPhone NDA tactics. One thing is sure though: People are really getting annoyed! Not being able to talk and discuss iPhone code before the release of the SDK was already unpleasant – but people were OK with it. Now unpleasant has turned into frustration. While Apple always had this thing for secrecy – this is becoming ridiculous. The NDA is still in effect. Discussions e.g. on Cocoa mailing lists are still not allowed. The whole world should still stay quiet.

Scotty from macdevnet has started an online petition. Maybe if sensibly passed on to the right people… Not much – buch at least something we can do. Please sign!

Dear lazyweb, I have come across a set of compressed data. I am trying to decompress it. It’s no inflate, it’s not bzip2 and it’s not gzip. Anyone recognizing what this could be?

Update: Turns out this is still deflate - but DES enrypted. Boy I so hate this proprietary limbo. A new release of uif2iso4mac is out that supports the new format.
