Here’s a funny story about a guy who uses his remote desktop software on his stolen laptop to catch the thief.  While doing so, he had do endure lots of porn, which what the thief was watching mostly.

Of course, the laptop won’t ever be the same anymore, I’d at least dismantle that keyboard and painted over with clearcoat.

It was kind of frustrating because he was mostly using it to watch porn. I couldn’t get any information on him.

Here’s remote desktop software I use from LogMeIn, it’s free and works well with Firefox.

This might not be for all of you but for those Linuxers out there, here’s an example of how to setup your mirror:

(Mirror is a way of replicating one server to another btw if you didn’t know.)

To download the mirrors I use this script:
<script sync_mirror.sh>

#!/bin/bash
OPTIONS="--nosource --progress --postcleanup --ignore-release-gpg --ignore-small-errors --pdiff=none";
MIRROR=`basename ${0} | cut -f2 -d "_"`
DEST="/home/debian-mirror"
case "${MIRROR}" in
        "debian" )
                METHOD="--method=http"
                HOST="--host=ftp.de.debian.org"
                ROOT="--root=debian"
                DIST="--dist=etch,etch-proposed-updates"
                ARCH="--arch=i386"
                SECTION="--section=main,contrib,non-free"
                DEST="${DEST}/debian/"
                ;;
       "security" )
               METHOD="--method=ftp"
               HOST="--host=security.debian.org"
               ROOT="--root=/debian-security/"
               DIST="--dist=etch/updates"
               ARCH="--arch=i386"
               SECTION="--section=main,contrib,non-free"
               DEST="${DEST}/debian-security/"
               ;;
        "volatile" )
                METHOD="--method=http"
                HOST="--host=volatile.debian.org"
                ROOT="--root=debian-volatile"
                DIST="--dist=etch/volatile"
                ARCH="--arch=i386"
                SECTION="--section=main,contrib,non-free"
                DEST="${DEST}/debian-volatile/"
                ;;
        "multimedia" )
                METHOD="--method=http"
                HOST="--host=www.debian-multimedia.org"
                ROOT="--root=/"
                DIST="--dist=etch"
                ARCH="--arch=i386"
                SECTION="--section=main"
                DEST="${DEST}/debian-multimedia/"
                ;;
        "backports" )
                METHOD="--method=http"
                HOST="--host=www.backports.org"
                ROOT="--root=debian"
                DIST="--dist=etch-backports"
                ARCH="--arch=i386"
                SECTION="--section=main,contrib,non-free"
                DEST="${DEST}/debian-backports/"
                ;;
        * )
                echo "${0} called incorrectly"
                exit
                ;;
esac
debmirror ${OPTIONS} ${METHOD} ${HOST} ${ROOT} ${DIST} ${ARCH} ${SECTION} ${DEST}

</script sync_mirror.sh>

To setup the permissions I use this script:
<script permissions.sh>

#!/bin/bash
MIRROR=`basename ${0} | cut -f2 -d "_"`
DEST="/home/debian-mirror"
case "${MIRROR}" in
        "debian" )
                DEST="${DEST}/debian/"
                ;;
        "security" )
                DEST="${DEST}/debian-security/"
                ;;
        "volatile" )
                DEST="${DEST}/debian-volatile/"
                ;;
        "multimedia" )
                DEST="${DEST}/debian-multimedia/"
                ;;
        "backports" )
                DEST="${DEST}/debian-backports/"
                ;;
        * )
                echo "${0} called incorrectly"
                exit
                ;;
esac
echo "Setting Ownership"
chown -R www-data:www-data ${DEST}
echo "Setting File Permissions"
chmod -R 660 ${DEST}
echo "Setting Folder Permissions"
find ${DEST} -type d -exec chmod 770 {} \;

</script permissions.sh>

And then to pull it all together I have thefollowing directory structure (mirrors left out as it’s a ling list of files)

/home/debian-mirror/
|-- debian
|-- debian-backports
|-- debian-multimedia
|-- debian-security
|-- debian-volatile
|-- scripts
|   |-- permissions.sh
|   `-- sync_mirror.sh
`-- scripts.d
    |-- mirror_backports -> ../scripts/sync_mirror.sh
    |-- mirror_debian -> ../scripts/sync_mirror.sh
    |-- mirror_multimedia -> ../scripts/sync_mirror.sh
    |-- mirror_security -> ../scripts/sync_mirror.sh
    |-- mirror_volatile -> ../scripts/sync_mirror.sh
    |-- permissions_backports -> ../scripts/permissions.sh
    |-- permissions_debian -> ../scripts/permissions.sh
    |-- permissions_multimedia -> ../scripts/permissions.sh
    |-- permissions_security -> ../scripts/permissions.sh
    `-- permissions_volatile -> ../scripts/permissions.sh

And then I just setup a cronjob:

0 0     * * 0   root    /bin/run-parts --verbose /home/debian-mirror/scripts.d | /usr/bin/mailx -s "`uname -n` - Debian mirror sync completed" root

This was to disable the mirroring of one of the repositories I just need to remove the symlink from the scripts.d folder

Here’s Microsoft’s latest “I am a PC” ad and I think we could have replaced “I am a human” for “I am a PC” here.

Oh yeah, they did forget to mention that “I am a PC and my Vista sucks” and that the ad itself was made on a Mac.

For those of us who are anti-Windows and anti-Mac, we will benefit from learning how to make Ubuntu run super fast.

Here’s some great tips on minimizing processes to make your Ubuntu run faster than ever:

1. Remove Network Manager if you do not need it “sudo apt-get remove network-manager”. If possible give yourself a static IP in /etc/network/interfaces like so:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.150
netmask 255.255.255.0
network 192.168.1.100
broadcast 192.168.0.255
gateway 192.168.1.1

Having a static IP helps with boot time as your machine doesn’t have to communicate with the router/dhcp server as much to obtain an address.

2. Also remove firestarter or whatever graphical firewall frontend you’re using. Learn to control iptables at boot up and shutdown. It’ll be much snappier.

3. Install bum, “sudo apt-get install bum” and run it with root access. Shut off all unnecessary services. If you’re not sure about a service research it before shutting it off. Also, install sysv-rc-conf. Run the application as root. This will allow you to control, in an easy way, what services start at which run level. It’s like bum, but more detailed. Be very careful with which services you are removing from which run-level. If you don’t know what you’re doing here, research it or don’t touch it. After you do this you may want to reboot to make sure you didn’t break anything.

4. Turn off usplash in grub. (Mind you, you’re bootup won’t be as pretty as the splash will go away).

• vim /boot/grub/menu.lst
• on the kernel line delete the words “splash” and “quiet”
• Reboot to see the changes.

5. If you have a dual core processor, you can decrease your boot time with concurrency.

• sudo vim /etc/init.d/rc
• and find the line CONCURRENCY=none and change it to: CONCURRENCY=shell
• Reboot to see the changes. (tired of rebooting yet?)

6. Remove some TTYs

I could easily do this by editing /etc/inittab and then commenting the extra TTYs there. With the new upstart mechanism in place, things are a little different.

You have to edit /etc/default/console-setup file. This file defines how many ttys should you get.

Change ACTIVE_CONSOLES=”/dev/tty[1-6]” to the number of consoles you want. Lets say, 3 ttys, then change it to “/dev/tty[1-3]“.

And then goto /etc/event.d/ and change the ttyx files that you DONOT want. Edit them and comment lines starting with “start on runlevel”. So, in this case, you’ll comment the start line in tty4..tty6 files.

Rebooting shoud minimize the number of consoles for you. Worked for me!! Good luck, NOTE: Even though you’ve reduced the tty number, X is still on Alt-F7. Again, go ahead and reboot to make sure you didn’t break anything.

Here’s a nice example of how hackers can easily freeze memory of the computer to retrieve the encryption key.

Abstract Contrary to popular assumption, DRAMs used in most modern computers retain their contents for seconds to minutes after power is lost, even at operating temperatures and even if removed from a motherboard. Although DRAMs become less reliable when they are not refreshed, they are not immediately erased, and their contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images. We show that this phenomenon limits the ability of an operating system to protect cryptographic key material from an attacker with physical access. We use cold reboots to mount attacks on popular disk encryption systems — BitLocker, FileVault, dm-crypt, and TrueCrypt — using no special devices or materials. We experimentally characterize the extent and predictability of memory remanence and report that remanence times can be increased dramatically with simple techniques. We offer new algorithms for finding cryptographic keys in memory images and for correcting errors caused by bit decay. Though we discuss several strategies for partially mitigating these risks, we know of no simple remedy that would eliminate them.

Drink a lot of beer in the bottles and have too much recycling every week?

Don’t worry, you can turn your empty beer bottles into powerful solar-powered LED beer lanterns that will light up your house at night for free.

Al Gore and company have helped us to see that our planet is in peril. Lend a hand, make a toast, and help illuminate ways for saving Earth — all at the same time! It’s easy to do your part: recycle, refill, and recharge. Just take your fave beverage bottle (keep the cap), drop in a flexible solar panel, a step-up switching regulator circuit, a rechargeable battery pack, and a powerful LED, cap it, and you’ll have a self-sufficient garden lantern that is ideal for shedding some light on solving environmental issues. You will have to choose your bottle carefully, though. Clear glass rules. Also, wide-mouth bottles are easier to convert than narrow opening long-neckers. Like your grandfather who built ships in discarded bottles, put a modern spin on bottle building while being conscientious of your world. Cheers!

When did Ctrl+Alt+Del phenomenon start?  Well, it probably goes back to the days of DOS operating system but Windows made it practical and famous with its blue screens of death.

These Control Alt Delete Cups will let you free yourself from stress by drinking the keys, not punching or hitting them with your fists.  (I have to admit that on many occasions using Windows 95 and 2000, I did punch out couple of Control, Alt, and Delete keys.)

You know when it comes to New Years and Independence Day, you always get to see some really exotic, beautiful fireworks.  Well, all those fireworks are nowdays controlled by an ignition control system but here’s how to make one for yourself.

At the heart of my firework ignition system is an SX48 running at 50 MHz. I was able to make full use of the SX’s 36 IO pins. Thirty lines are dedicated to the 30 channels. Two lines connect to a MAX233 chip for serial port control. Another line is connected to a 7805 (TO-92) which monitors the state of the arming key. The remaining 3 lines are used to communicate with the PIC A/D converter via an SPI interface. The system was built with cost as an important factor. At $10 the SX48 Proto board was an easy choice with its incorporated 5V regulator, led and all the difficult surface mount soldering already done for me. I also designed 2 pc boards using the freeware version of Cadsoft’s Eagle. The interface board connects the SX48 Proto board and contains the MAX233 chip, A/D converter and 30 LEDs to represent the state of each of the 30 channels.

You know those telepromopters that TV news reporters use to read their daily news?  Well, here’s a simply way to make a teleprompter for any type of presentations.  (This one is an example for a church but I don’t see any reasons why you wouldn’t use it outside god’s house.)

1. Whatever you do…. no matter what…. and this is job #1 so pay attention…. always have a paper copy of your notes in your suit pocket.     Allow me to repeat myself — Have paper backup of your talk.    To sum up this point:  Make sure you have your notes on paper, and easily accessible in case your computer dies.
2. Write your talk, refine it and get it to the point where you would normally print it out as notes. In my case I work from a hybrid of a bullet point outline & written-out quotations.
3. Enter those notes,  page by page into a power point presentation.   Use huge font, as it is irrelevant how many slides/pages you use.
4. Get a “wireless presenter”    You plug a small receiver into any USB port, then hold the tiny clicker in your hand.  My clicker is 1-1/2 inch across, 3-1/2 inches long and about 1/2 inch thick.  It fits easily, and unobtrusively into your hand.   No one will even notice it.
