Default root password on iPhone 3.0

Just installed SSH, was able to login with:

- root / alpine
- mobile / alpine

You can change the default passwords if logged in via SSH by using the 'passwd' command for both accounts.

How to mount an LVM partition

This details the commands I had to run to mount a CentOS 5.1 main disk into another machine. Because of LVM using mount on standard scsi partitions is not enough.

Assuming main physical disk: /dev/sda
Second physical disk: /dev/sdb

1. Run pvscan to list the physical volumes found in any block device of the system. Among error lines this returned PV lines for /dev/sda2 and /dev/sdb2. On the same line was the name of the volume group, in my case 'sysvg'
2. Made the 'sysvg' volume group active by typing lvchange -ay sysvg. This created a new entry in the /dev/sysvg
3. Doing an ls /dev/sysvg showed the different volumes under that volume group, from there simply had to do: mount /dev/sysvg/root.vol /mnt
4. When done: umount /mnt && lvchange -an sysvg

GWT disable text selection in an HTMLTable

While modifying FlexTable to handle cell selection It took me a while to figure out how to disable the native text selection behavior of the browsers on 'SHIFT+Click' events. Turns out this native javascript function does the job pretty well. I tried playing with event.preventDefault() and event.stopPropagation() but that didn't work.

private native static void disableTextSelectInternal(Element e, boolean disable)/*-{
    if (disable) {
        e.ondrag = function () { return false; };
        e.onselectstart = function () { return false; };
        e.style.MozUserSelect="none"
    } else {
        e.ondrag = null;
        e.onselectstart = null;
        e.style.MozUserSelect="text"
    }
}-*/;

@Override
public void onKeyDown(KeyDownEvent event) {
    if (event.isShiftKeyDown()) {
        disableTextSelectInternal(table.getElement(), true);
    }
    ...

How to disable GZIP compression in Firefox

Not sure this is the only/best way but I used the following steps to disable gzip compression in Firefox 3.0:

1. Type about:config in the URL bar (Accept the disclaimer)
2. Type encoding in the filter field underneath the URL bar
3. Doubleclick the line network.http.accept-encoding
4. Enter the following value instead of the default: gzip;q=0,deflate;q=0

Note: See comment from Anonymous below for a possible better way of doing this. Thanks Anonymous!

Delete Flash9f.ocx - Access is denied

After installing Windows 7 on an XP partition I couldn't completely get rid of the Windows.old folder. The culprits were a few ocx and dll files left with strange permissions by Adobe Flash and Acrobat. All attempts to take ownership and delete failed.

I was finally able to delete these files easily thanks to Unlocker.
