The first time I flew in turbulence was 2007-01-05. It was a solo flight from KSEE to KSZP (Gillespie in San Diego to Santa Paula) a few weeks after I received my pilot certificate. I had flown the route a few times before, but always in clear and calm weather.This time, it was a bit windy when I took off - nothing major. I opened my flight plan and got flight following, and proceeded to climb to

If you are using KDE's konsole, it has built-in support for the Zmodem protocol.I often SSH into remote machines via "hopping" SSH which makes it annoying to copy files back. But installing lrzsz on both my machine and the remote machine, and using konsole allows me to type:sz file.txtAnd konsole will ask me where I want to save it on my local machine. I've heard it works in Tera Term, also.

I was trying to use Chromium on Ubuntu 10.04 Lucid Lynx, and Flash was working, but about:plugins revealed that it was version 9 whereas I wanted 10.It turns out that all I had to do was delete ~/.mozilla/plugins/libflashplayer.so which was left over from long ago. I'd already enabled Adobe Flash 10 in the Ubuntu Software Manager, and once that file was gone, a restart of Chrome let it see the

I was trying to make a case statement in bash, and was getting this error: ./check: line 8: syntax error near unexpected token `)' ./check: line 8: `      1)' Turns out this is the error you get if you forget the ;; at the end of each code block.

I loaded Beta 2 of Lucid Lynx on a machine; it wouldn't get past the splash screen. I had to hit the spacebar during the Live CD boot to get it to show the boot log; this prevented the splash screen from loading and allowed me to install. But it wouldn't boot afterwards; it would lockup in the splash screen. Turns out that the menu fr Grub 2 can only be accessed if you hold SHIFT down while

I was trying to install Windows 7 on a system, and it wouldn't see the SATA drive. All evidence pointed to the drivers being correct and not needed; but the drive wouldn't appear. Finally I determined that because the drive had a dynamic disk on it, Windows 7 setup wouldn't even acknowledge that it existed. I booted Ubuntu and wiped the partition table, and then it worked fine.

I have a SiS900 Ethernet controller that I could assign IP and IPv6 addresses to, but I couldn't bring it up. mii-tool reported that the link was negotiated, and it had worked before my recent kernel compile. I tried everything I could think of, and recompiled the kernel over and over again. Finally I realized that the other thing I'd changed was turning off SMP support - I turned it back on,

To enter Unicode characters in Ubuntu, simply hold down CTRL+SHIFT+U which will create an underlined u: u Then type the hex code for the character you want (with no 0x or anything like that), followed by enter. ∎ (That's 220E, the "QED" character).

Lilypond by default prints key cancellation and then prints the new key signature, even when at the end of a line. No doubt these are helpful to musicians or something, but they look horrible, and can get out of control. It turns out it's relatively complicated to get rid of the cancellation and the new one without removing the normal signature from the following line. However, the following code

This should work for any X.org based Linux system. The key is to point it at the right event id as follows in /etc/X11/xorg.conf : Section "InputDevice"         Identifier "touchscreen"         Driver "evtouch"         Option "Device" "/dev/input/by-id/usb-NextWindow_Touchscreen-event-mouse"         Option "DeviceName" "touchscreen"         Option "MinX" "1"         Option "MinY" "1"

I have an OpenVPN machine on my network that hosts a VPN, but it is not the default router for the network. I wanted to forward a port for the OpenVPN clients so that they could see another machine on the local network. To do this requires a number of steps. First, the machine that they'll be connecting to needs a default route added for the OpenVPN network, or the packets will never return. My

It turns out that the self-assigned IPv6 addresses you see are not unique; they're only guaranteed unique on each interface. To ssh to one, you'd need to run:ssh fe80::21c:c0ff:fe52:c5ec%eth0for example, where %eth0 specifies eth0.

I have a number of bash scripts that do useful things to lists of items, such as this:./install_stuff.sh 10.0.0.2 10.0.5.3By using shift, I can have the script run through various IP addresses, for example. But I wanted more. I wanted the same command to sometimes take -t tag as an option and do something different. It turns out there's a relatively easy way to do this using the getopts builtin

Sometimes you have too many SSH keys loaded, and trying to SSH to a box will fail. Sometimes you're trying to SSH to a box that's been rebooted into another OS or from a rescue CD.The following command will disable key-based authentication, and ignore your known_hosts file:ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o'RSAAuthentication=no' -o 'PubkeyAuthentication=no'

I had a Xen domain crash, and it was a file image based LVM system.

When trying to upgrade my kernel on a Gentoo box I got the above error. Many people discussed it, but all the solutions seemed to be "it went away." However, I couldn't get it to stop occurring until I told Gentoo to rebuild the entire toolchain used by genkernel:emerge --emptytree genkerneland then rerunning genkernel solved the issue. The best hint seems to be that it is something to do with a

Because VMware is aimed at CentOS, by default the hgfs shares are set up to be owned by the user with id 501; you'll need to change this so that it's owned by your user. To do this, first run `id`: $ id uid=1000(user) gid=1000(user) Then edit `/etc/fstab` and change the line: # Beginning of the block added by the VMware software .host:/ /mnt/hgfs vmhgfs defaults
