Search Linux Kernel code from Google Chrome

2011-10-25T08:31:00.003+02:00

If you're a kernel developer, you must be familiar with Linux Cross Reference (LXR) sites.. there are a few of them out there, but I find http://lxr.linux.no the most convinent and the the fastest, it also uses a newer version of LXR than others.

If you're a Google Chrome user, you can easily add a new custom search type for LXR:
1. Open chrome and go to: chrome://settings/searchEngines
2. Add the following entry: Search engine: lxr.linux.no, keyword: lxr, Query: http://lxr.linux.no/linux/+search=%s

3. Now you can search for any Linux kernel symbol directly from chrome, for example: go to the toolbar and type "lxr skb_dst"

4. Chrome will build the URL query for you, and results are shown directly in the browser tab.. happy kernel browsing :)

Major Linux Hackers

2011-10-01T03:15:00.004+03:00

These people had major influence on the Linux Kernel (code talks and bullshit walks).

Mostly known by their code, patches, comments.. it turns out that they are human beings with real photos :)

Linus Torvalds: Software is like sex: it's better when it's free.

I found the following two quotations very funny (fame oh fame):

1991: "I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386/486 AT clones"

1998: "My name is Linus Torvalds and I am your god"

Sony HX100v - GPS location

2011-06-23T11:04:00.002+03:00

The new Sony HX100 is GPS-enabled, this feature is very cool, especially when paired with Google Picasa.
For Example, when you upload a photo to picasa web album, the location on the map is viewed automatically (make sure that location permission is granted).

And, also through Picasa application on your computer, if you have Google Earth installed, you will be able to see a small icon of Google maps on the photo, then you can click on Geo-Tag button, and Google Earth will be launched and will show your picture location.. neat ha?

Sony HX100v - 10fps Collage

2011-06-23T10:22:00.006+03:00

Finally got my new Sony HX100v, a lot of features I'd like to try.

My favorite feature is the 10 frames per second (each is full resolution of 16.2MP).. this feature existed in the previous HX1 as well.. first day trying me new camera I got this collage.. click on the picture for better resolution, or check zoom-in option under this link.

To make collage (especialy for such a nice feature) you can use Google Picasa and follow these simple steps.

Select the photos and click on Collage:

Edit the Collage settings, and generate the collage photo!

Xen Installation on CenOS-5.5

2010-12-09T01:11:00.017+02:00

As part of my work, I had to bring up Xen Servers setup, and install some virtual machines.
I've been working on VMware ESX Servers for a while, and I must admit that VMware products are way more mature than Xen products. Below step by step installation of Xen over CentOS-5.5 and how to bring up and configure DomU Virtual Machines.

Dom0 Installation:
-----------------
1. Install CentOS-5.5 OS
   ISO is downloadable from here
2. Install Xen kernel and Tools:
# yum install kernel-xen kernel-xen-devel xen

# yum install virt-manager
# yum install virt-viewer
3. Edit /etc/grub.conf and select xen kernel

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-194.26.1.el5xen)
   root (hd0,0)
   kernel /xen.gz-2.6.18-194.26.1.el5
   module /vmlinuz-2.6.18-194.26.1.el5xen ro root=LABEL=/ rhgb quiet
   module /initrd-2.6.18-194.26.1.el5xen.img
title CentOS (2.6.18-194.el5)
   root (hd0,0)
   kernel /vmlinuz-2.6.18-194.el5 ro root=LABEL=/ rhgb quiet
   initrd /initrd-2.6.18-194.el5.img
4. Reboot the machine
5. Check kernel name, it will have xen substring:

# uname -a
Linux eng-023.mti.mtl.lab.com 2.6.18-194.26.1.el5xen ...
6. On my machine, yum installed Xen version 3.0.3:

# rpm -qa|grep -i ^xen-[0-9]
xen-3.0.3-105.el5_5.5

DomU Installation:
------------------
1. run virt-manager from dom0
2. select server name in the table, and select "new"
3. configure the virtual machine, when you get to the installation media, you better have the installation dir (extracted iso) available through on your network (check this link if you want to bring up your own apache) note that for full Linux installation (e.g., for RHEL-5.5) you need more than 4GB virtual disk space (I use 8GB).
4. when installation is done, machine will reboot and come up with bridged network connection
5. If you configured your VM to use DHCP, then you're ready, go ahead and ping the WAN.
- For more info on how to use virt-manager to install DomU instance (with snapshots) check this link.

DomU Network Configuration:
---------------------------
Xen supports three modes for network virtualization:
Bridging, Routing w/o NAT, Routing with NAT, each one of them need to be configured differently.

By default, the network is set up in bridging mode.
To change the network configuration, there are two main configuration files:
# /etc/xen/xend-config.sxp (hypervisor conf)
# /etc/xen/VM-NAME (virtual machine conf)

DomU in Bridging mode:
----------------------
1. Make sure that xend-config.sxp has the following lines:
   (network-script network-bridge)
   (vif-script vif-bridge)
   To use different netdev (rather than eth0) use the line:
   (network-script 'network-bridge netdev=eth1')
   To create multiple bridges, you must create your own script.
   For example, in xend-config.sxp add:
   (network-script network-bridge-multi)
   The cerate the file (with +x permissions):   # cat /etc/xen/scripts/network-bridge-multi
   #!/bin/sh
   dir=$(dirname "$0")
   "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0
   "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1
   "$dir/network-bridge" "$@" vifnum=2 netdev=eth2 bridge=xenbr2
   check this link for more details.
2. Configure DomU virtual interfaces,
   Edit /etc/xen/VM-NAME and examine the following line:
   vif = [ "mac=00:16:36:69:0d:0b,script=vif-bridge,bridge=xenbr2" ]
   where xenbr2 is an example of the bridge name
3. Note that if the netdev of the bridge your going to use was created after machine reboot, then you need to restart the xen network script, for example:
# /etc/xen/scripts/network-bridge stop
# /etc/xen/scripts/network-bridge start
If the pethX interface you expect does not come up, try to reboot the machine (I noticed that in Xen 3.0, the network-bridge may fail to create the pethX interface if you restart the script few times, reboot solved the issue)
4. Make sure that the bridge as appear in brctl is output, is configured as expected:
#brctl show xenbr2
bridge name bridge id STP enabled interfaces
xenbr2 8000.00.. no vif2.0
   peth2
If you configured your system in the past to work in routing mode, you may see virbr0 instead of xenbr0, to revert these changes, run:
# service libvirtd stop; chkconfig libvirtd off
If for some reason the peth2 that coresponds to your netdev is not attached to the bridge, then find your peth:
# ethtool -i peth2
and then add the interface to the bridge:
#  brctl addif xenbr2 peth2
If for some reason, peth2 link is down, run:
# ip link set peth2 up
At this point you can run the VM, configure the IP, and heck ping-pong, you can tcpdump the bridge (xenbr2) and its slaves to check the packets flow.

DomU in Routed mode:

--------------------

Note that most of the tips of this section are based on this link.
1. Update your grub entry to include the following parameters:

title Kernel-XXX-xen
   root (hd0,5)
   kernel /boot/xen.gz
   module /boot/vmlinuz-XXX-xen root=/dev/sda6 vga=0x31a resume=/dev/sda5 splash=silent showopts
   module /boot/initrd-XXX-xen
2. Set netloop driver module parameter, edit /etc/modprobe.conf and include the line (to top netloop from creating 8 useless vifs):
options netloop nloopbacks=0
3. Reboot Dom0
4. Configure Dom0 networking, edit /etc/xen/xend-config.sxp and include the line:

(network-script network-route)
(vif-script vif-route)
5. Configure DomU networking, edit /etc/xen/VM-NAME and include the line:
vif = [ 'mac=00:16:3e:33:22:11, ip=192.168.23.1, vifname=eth0' ]
Where the IP address, is the IP address you plan to give to vifname interface within the VM.
6. Power on the VM, and conifgure (for example) the eth0 interface to use the IP=102.168.23.1
7. Ping the IP address of Dom0 (run ifconfig from Dom0 and check your netdev IP, must start with 192.x.x.x [depends on your mask]).
8. To ping other machines outside the GW, need to configure the default GW in the VM, this can be done in many different ways, for example:
route add default gw 192.168.23.254 eth0

Troubleshooting:

----------------

- If you get the error message:

ERROR unable to connect to 'localhost:8000': Connection refused

You probably don't have xen-http-server enabled, edit:

/etc/xen/xend-config.sxp

and include the line:

(xend-http-server yes)

then restart xend:

/etc/init.d/xend restart

GIT Tips

2010-10-26T05:02:00.005+02:00

While looking for GIT configuration for "signed-off-by" line, I found this nice link for GIT tips.
It has nice git-config commands that you might find useful in general.

Specifically, to automaticaly add the "signed-off-by: NAME " line into your git commits, run the following two commands:

git config user.name 'Your name'
git config user.email 'my@email.com'

I also found this nice link while searching for git cherry-pick, thanks for sharing.

Extract vSphere Installation Bundle

2010-10-05T05:55:00.010+02:00

If you happen to need to extract vSphere Installation Bundle (vib), this can be done by running the following:

- Extract the zip archive:

unzip BUNDLE.zip

Two files will be created, metada.zip and VIB.vib

- Extract the vib archive

ar -x VIB.vib

The following files will be created:

control.tar.gz

data.tar.gz

debian-binary

descriptor.xml

short.rpm sig.pkcs7

- Extract data.tar.gz
tar -xzvf data.tar.gz

The result would be the files you are looking for. enjoy!

Note:

- ar command is normally not available on ESX Server, run this command on Linux.
- I added support to this script to recognize vib extension.

Run as daemon in Linux

2010-09-30T23:27:00.008+02:00

In Linux, when a command is executed from a terminal window, it will be child of that window's PID. For example, see below how xlogo is parent of the terminal:

# open terminal window:
# echo $$

4830

# xlogo &

4956

# ps -l | grep xlogo

0 S 1049 4956 4830 0 75 0 - 9979 - pts/11 00:00:00 xlogo

As a result, whenever you close the terminal (parent) window, the xlogo will terminate.

If you wish to run your application as daemon, use the command NOHUP(1), this will make the running application immune to hangups. For example, see how xlogo is child of PID 1 (the init process):

# open terminal window:

# echo $$

4830

# nohup xlogo &

5013

# close the terminal window

# ps -l|grep xlogo

0 S 1049 5013 1 0 75 0 - 9979 - pts/11 00:00:00 xlogo

SSH Host key verification failed

2010-09-28T20:09:00.005+02:00

If you keep getting this annoying SSH failure:

I used to edit known_hosts file and remove the record that coresponds to the remote host IP,

a simpler way is to run the command:

# ssh-keygen -R REMOTE_IP

Linux Sign Generator

2010-09-28T06:01:00.004+02:00

I came across this nice image generator of Linux penguine holding a sign with custom text, give it a try.

I recommend using 20pt pixels font with black color, like the one I used in this sed post.

You can also edit the link directly and just replace the text, for example, to generate a sign with above setting and the test "Linux Sign Generator" then the link would be:
http://www.images-graphics-pics.com/signs/signs/linux/?allow=&text=Linux+Sign+Generator&fontsize=20&font=pixels&color=black&move=20

Note: the character + used for spaces

Sed by Example

2010-09-28T05:44:00.011+02:00

As you probably know, sed is a very powerful tool in Linux for filtering and transforming text.

I was looking for some commands with regular expression to process some configuration files in Linux, and I found this link that teaches sed by example, it's informative and easy to understand.

Useful links:

Note: If you read Arabic, sorry for the picture, no offence (I still find it funny) If you do not read Arabic, never mind.

Check multiple machines availability

2010-09-20T04:59:00.007+02:00

Usually, administrators check machines liveness by sending ICMP echo request (aka ping request).

I found this tool very handy to check the liveness of multiple machines very quickly from command line. The tool is called fping, and it can be installed on Linux using this tar ball.

Example:
Define your machines IPs configuration file:
# cat machines.ips
10.20.1.19
10.20.1.20
10.20.1.21
10.20.1.22
10.20.1.23
10.20.1.24
10.20.1.25
10.20.1.26
10.20.1.27
10.20.1.31
10.20.1.32

Now, run fping to check the machines availability:
# fping -f machines.ips -r 1 -t 100
10.20.1.19 is alive
10.20.1.20 is alive
10.20.1.21 is alive
10.20.1.22 is alive
10.20.1.23 is alive
10.20.1.24 is alive
10.20.1.26 is alive
10.20.1.27 is alive
10.20.1.31 is alive
10.20.1.32 is alive
10.20.1.25 is unreachable

Script Header Generator

2010-09-20T04:15:00.008+02:00

If you write a lot of scripts, you are aware of the importance of the scripts headers.
General, script header define the script language, usage, description, author..

I wrote this script, that generates a script header based on the template below, the script tries to identify the script language and usage automatically, in addition to some other fields, variables that need to be set manually are marked with "TBD" such as script description.

Feel free to change the AUTHOR and AUTHOR_EMAIL in the script to your own strings.
I found this scripts very useful to fix the header of hundreds of scripts I have that didn't include the appropriate header. Share and Enjoy.

Example, to generate the header of the script test.py, run:
$ ./create_header.py test.py

#!/usr/bin/env python

The ARP Flux Problem

2010-09-20T02:18:00.006+02:00

If you spent a lot of time trying to understand why a network interface in Linux fakes ARP replies on behalf of another interface, you may be facing the ARP flux effect! Yes, this is how it's called, and yes, you spend many hours debugging problems due to this weird behavior.

Surprisingly, this is a known behavior of Liux ARP module, when a a machine has multiple network interfaces, as stated in O'Reilly Book: Understanding Linux Network Internals:

The solution of the flux problem is through altering the system sysctl parameters, few websites (see references below) suggest how to make the suitable changes.

To make this process easier, you can use this script to set the right values into the procfs files.
To make the changes permanent (kept among reboots): the following can be added to your /etc/sysctl.conf file:
sysctl -w net.ipv4.conf.all.arp_ignore=1
sysctl -w net.ipv4.conf.all.arp_announce=2

Tip:
To flush the ARP table in Linux, use this helper script.

objdump parser

2010-07-30T04:50:00.007+03:00

If you've been programming in Linux kernel, you must had the chance to debug kernel oops using objdump.
Normally, you invoke objdump with the name of the problematic driver, and then parse the output based on the information printed in the call trace of the kernel oops. Here is a nice example.

Among many hexadecimal numbers and function names that are printed in the call trace of the kernel oops, the most important piece of information is the function name and the offset: for example:
vnic_login_create_2+0xd1

I wrote this script that receives the function name and offset as a pointer, and prints the source file name and line number that caused the oops.

For example:
# objdump_parser.py vnic_login_create_2+0xd1 drivers/net/mlx4_vnic/mlx4_vnic.ko

vnic_login_create_2+0xd1 = 0x6e3 => drivers/net/mlx4_vnic/vnic_data_main.c:210

"always on top" option for Windows

2010-07-21T00:58:00.001+03:00

Always On Top Maker is a tiny interface less tool to make any window "always on top", or, make a topmost windows not always on top. How to use: Run AlwaysOnTopMaker.exe, then you can use 2 hot-keys, one is CTRL-ALT-T, is to switch the foreground application "always on top"/"not always on top", the other hotkey is CTRL-ALT-Q, is to exit Always On Top Maker.

netconsole for redhat

2010-07-10T02:07:00.016+03:00

Net-Console module logs kernel printk messages over UDP allowing debugging of problem where disk logging fails and serial consoles are impractical. It can be used either built-in or as a module. As a built-in, netconsole initializes immediately after NIC cards and will bring up the specified interface as soon as possible. While this doesn't allow capture of early kernel panics, it does capture most of the boot process. it's very useful for kernel developers to dump kernel oops callstack (source).

The configuration in Red Hat is very simple:

On the monitor machine:
1. Edit /etc/sysconfig/syslog and include the line SYSLOGD_OPTIONS="-m 0 -r -x"
2. Run dmesg -n 8
3. Restart syslog service: /etc/init.d/syslog restart

On the development machine (that may have kernel oops):
1. Edit /etc/sysconfig/netconsole and include the line SYSLOGADDR=(monitor-machine-IP)
2. Restart netconsole service: /etc/init.d/netconsole restart

Now you can work on the development machine and watch its kernel messages on the monitor machine, I watch the development machine by running this command on the monitoring machine:

#tail -f /var/log/messages | grep (devel-machine-ip)

Below some useful bash scripts for your convenience:
netconsole_devel_set.sh
netconsole_monitor_set.sh
netconsole_monitor.sh

Tip:
If you're using remote console switch, you can check the console output by invoking the command:
# echo `date`: Hello from `whoami` > /dev/ttyS0

To test netconsole, you just need to trigger any kernel module that prints messages into /var/log/messages, for example:
# modprobe -qr tun; modprobe tun

If your running in Dom0 of Xen/KVM, the netconsole script get confused by the interface bridging, to fix this, you need to update /etc/init.d/netconsole:
First, find the corresponding peth interface of the netdev interface you want to use for netconsole, normally if you're using eth0, then the corresponding inetrafce in Xen is peth0, then find the MAC address of the remote logger IP, for example if the remote sys logger is 10.20.1.20, find its MAC by running:

# ping 10.20.1.20 -c 1 ; arp -n | grep 10.20.1.20

And finally, include the following two lines in /etc/init.d/netconsole:

DEV=peth0 #your peth name here

SYSLOGMACADDR=00:30:48:7D:DE:E4 #your MAC here

At this point you can use the scripts above to enable netconsole.

SMS notification for Linux commands

2010-07-08T01:25:00.007+03:00

Sometimes you need to run a Linux command that may take time (such as kernel compilation, virus scan, long test run..) instead of waiting in front of the monitor, you can do other stuff (e.g., good coffee) and you'll be notified when the command had finished with the results.

I have ATT cell phone, they support SMS2EMAIL service; simply send a message (plain text, no longer than 160 characters) to the address:

(your-number)@txt.att.net

For example:

4081002000@txt.att.net.

The Email address varies based on your carrier, check this website for worldwide cellular network list.

Now, we just need to run the command that takes time, and send a short text message with the report to notify us.. from a Linux machine with Email access, run this command:

(msg-body) | mail -s (msg-subject) (sms2email-address)

The message body can be the command output, or the command returned code, or anything else you want.

Examples:
a) To report the returned code of an application, run:
gcc  windows.c; echo "rc=$?" | mail -s "gcc report" 4081002000@txt.att.net
This will send you the returned code (rc) of the compilation command when its done, usually zero (rc=0) indicates a successful run.
 

b) To compile a Linux kernel and send an SMS when done with the output tail (last 120 bytes for example), run:

make 2>&1 | tail -c120 | mail -s "Kernel Compilation Status" 4081002000@txt.att.net

Notes:
- You may need to adjust 'tail -c' flag to fit into 160 characters, see 'man tail' for more info.
- To redirect command error messages, use the suitable bash redirection methods.
- ATT sucks.

Fix Slow SSH Login Time

2010-07-07T11:13:00.001+03:00

If your login times are really high, it may be that reverse DNS is not working correctly.

Solutions:

(a) Disable DNS in SSH daemon: go to /etc/ssh/sshd_config and include the line UseDNS no, then restart ssh service: /etc/init.d/sshd restart

(b) Or, fix your DNS configuration: in redhat, go to setup -> Network Configuration -> Edit DNS configuration -> and set the primary DNS and the search domain

Tips for better cscoping

2010-01-12T22:42:00.004+02:00

Cscope is a developer's tool for browsing source code. It has an impeccable Unix pedigree, having been originally developed at Bell Labs back in the days of the PDP-11. Cscope was part of the official AT&T Unix distribution for many years, and has been used to manage projects involving 20 million lines of code! I use it a lot of work to manage browse the code of several kernels (any other editor I tried failed to do the job in reasonable time, cscope did handle it!)

Here are few tips for better cscoping:
- Display more pathname components in search results with -pN. By default, cscope only displays the basename of a given matching file. In large codebases, files in different parts of the source tree can often have the same name (consider main.c), which makes for confusing search results. By passing the -pN option to cscope at startup (or including -pN in the CSCOPEOPTIONS environment variable) -- where N is the number of pathname components to display -- this confusion can be eliminated. I've generally found -p4 to be a good middle-ground. Note that -p0 will cause pathnames to be omitted entirely from search results, which can also be useful for certain specialized queries.

- Use the built-in history mechanisms. You can quickly restore previous search queries by using ^b (control-b); ^f will move forward through the history. This feature is especially useful when performing depth-first exploration of a given function hierarchy. You can also use ^a to replay the most recent search pattern (e.g., in a different search field), and the > and < commands to save and restore the results of a given search. Thus, you could save search results prior to refining it using ^ (as per the previous tip) and restore them later, or restore results from a past cscope session.

home/end keys on putty

2009-11-11T22:52:00.008+02:00

For who's using putty for SSH connections, you may noticed that by default home/end keys don't work.. to enable them:

- Open putty

- On the left panel, go to Connection/ Data

- Change terminal-type string to "linux"

- Go back to sessions window and connect to your machine

And if you want to enable "copy/paste" using middle mouse button:

- On left panel, go to Windows/ Selection

- Select "xterm"

Bring up Linux Apache Server & symbolic links access

2009-07-31T01:52:00.017+03:00

I wanted to bring up an HTTP server on Red Hat 5.3 to browse a NFS directory and share it with my colleges. The basic configuration went very easily, however, accessing the soft links was a nightmare! so I would like share the solution here to save time for other people who face the same problem. I found a lot of articles about this, this one was great. Basically, you need to edit /etc/httpd/conf/httpd.conf and include this line under the "Directory" XML element of the directory that includes the symbolic links you want to enable:

Options FollowSymLinks

However, it was not enough for my case, and my problem was SElinux! once I disabled it, everything worked like a charm. To control (disable) SElinux follow instructions at this link. Basically, to disable SElinux temporarily, run:

echo 0 > /selinux/enforce

Thanks for the people who documented their troubleshooting and helped solving the problem.

P.S.
To set your web server for easy file access:

- comment out all lines in /etc/httpd/conf.d/welcome.conf
- edit /etc/init.d/httpd.conf
- echo 0 > /selinux/enforce
- Modify the line "DocumentRoot /var/www/html" to point to your path
- Modify the line "Directory /var/www/html" to point to your path
- chkconfig httpd on
- service httpd restart
- Got to any host any browse http://server-ip

Where two spirits become one

2009-06-06T10:32:00.007+03:00

In love, there is no ground, free uncontrolled fall, like jumping from the sky and seeing no end.. no rules applies, no gravity, just me and my love to endless destiny.. where two spirits become one, inseparable.. until death.

What is hard to keep, what is hard to lose, what is hard to leave, is also hard to give from the beginning... life tough me that valuable and unique things aren't on surface... they are deep inside.. Close to the heart.. not easy to get there.. otherwise all people would get them, and they will lose their uniqueness.

Take a moment, before you go to sleep, go through your life memories.. See how: easy comes - easy goes.

A friendship scar

2009-05-14T10:12:00.006+03:00

It's interesting how emotions can cross any physical distance and have their effect on humans.
I've been always obedient to friendship which is very valuable in life, however sometimes when I say what I think I hurt others' feelings.. problems is that doesn't matter if what I think was right or wrong, it always feels wrong to hurt others' feelings, especially friends, even if they are continents far from you! and what makes it even more complicated, is that even if you were wrong, sometime you hurt the other side so bad that he doesn't won't to listen to your apology, or even to let you realize that you were wrong and wish to change your mind!!
And you left bleeding with knife in your hand, you the one who hurt others, and for all that you are the one who's bleeding.. it's like fighting yourself, because you're human.. a human who makes mistakes.. and yet doing mistakes isn't enough to make you bleed, it's the well to excel and value friendship and fellowmen feelings which leaves unforgettable scars on your body. Only humans with scars are those who got into the battle, and exchanged theirs (and others) blood with booties, these booties are lesson of life, mine is; if I was that friend that got hurt, I would listen to what my friends have to say after they hurt me.. otherwise we'll both bleed to death!

Spaghetti.. Ali's spaghetti

2009-04-27T08:41:00.006+03:00

A quite weekend in San Jose, as other weekends I woke up late and started a new day (which is almost done). But today I will cook something, this reminds me of Technion days with my friends trying again to cook some "eatable" food.. we always ended up eating whatever we cooked, and sometimes (surprisingly) it was even delicious, thanks to Dr. Bashouti (also known as "The Chef") in most cases :)

Of course, no one can compete with My mom's food, but sometimes I try :) this time it was the traditional Arab recipe (yap, it's not Italian, we claimed it long time ago)..
Ingredients:
1. Spaghetti
2. Black olives
3. Tomato souse
4. Love

How to pass California DMV written test

2009-03-21T01:47:00.013+02:00

I just had my DMV (Department of Motor Vehicles) written test.

Here are some tips to pass it easily:
1. First make sure you have all the requirements for the DMV test.
2. Make an appointment via DMV website, this will save about 30 minutes waiting time in the office (the appointment is usually scheduled for 2 weeks later), but if you are in a rush, you can go directly to the DMV office. NOTE: if you are eligible for a SSN (Social Security Number) you must have it before you apply to the DMV test, otherwise they will not let you have the test unless you come back with SSN.
3. Read California Driver Handbook (a night before the test should be sufficient), this is very important, also check these sample tests here, here and here, many questions may appear in your exam "as is".
4. I recommend to watch these videos (this is the channel) on youtube, they explain a lot of things visually which makes it easier to understand.
5. When you're ready, got to closest DMV office, pay the fee (it's 27 dollars) you will have a vision exam (bring your glasses) and your fingerprint and picture will be taken. After that you get to the test, it's composed of 36 questions you're allowed to have 6 mistakes (if you're applying to new driver license), if you read the handbook this should be very easy (I passed it in 5 minutes with 100% grade)
6. When you pass the test, you will have a temporary license until your "behind the wheel" test, go ahead and make an appointment for the practical "behind the wheel" test, this can be done by phone call, online, or in the DMV office right after you finish the written exam. It's usualy scheduled for 3 weeks later.

Tips for the driving test (behind the wheel):
- Memorize hand signals.
- You should know the car you're driving, hand breaks, emergency lights..

it's much more.

KDE konsole tips

2009-03-20T03:31:00.004+02:00

I found KDE konsole to be most convenient for Linux programming and scripting.
Here are few tips that may make your life easier:

1. Change colors to something more friendly to you (and your eyes), I personally prefer dark font on light background (many others prefer black background), go to "settings", select "schema", select "black on light yellow". to make this change permanent; go to "settings", select "save as default"

2. Change tab name automatically; when you have many tabs, this change is handy: go to "settings", select "configure konsole", select "set tab title to match windows title"

3. Run command on all sessions: when you're running on multiple tabs on multiple machines, and you want to run same command on all of them, use this feature: open a tab for each machine, then go to one of them and right click then select "Send input to all sessions", after that everything you type will be replicated on all other sessions (machines).. nice one.

4. If you're waiting for an activity on specific session and you're tiered watching/checking each tab frequently, you can easily right click on the tab and select "monitor for activity", then when a new output appears on that session you will see a "pop up' windows reporting that, even if you are in different application.

5. Shortcuts! of course you must know these shortcuts as a Linux user :)
- New tab: ctrl + alt + n
- Rename tab: ctr + alt + s
- Close tab: ctrl + d (depends on your shell)
- Browse tabs: shift + right/left arrow
- Move tab: ctrl + shift + right/left arrow

Enjoy!

bash vs. tcsh

2009-03-17T00:40:00.005+02:00

I find it much easier to use BASH rather than TCSH, many articles in the wen explains why, so I will save few bits for Google robot and will not replicate this info.
However, it may be useful to know that to switch shell you can easly use 'chsh' or 'ypchsh' (make sure you have the correct permissions, otherwise contact your admin :-/) I had to contact my IT admin to do it for me.

Ah, and also here is a very nice (and advanced) bashrc file, to use it; copy the file to your home directory (named .bashrc) and you'll feel like superman, I mean root :)

Bash, feels like home :)

VNC Auto Start and Copy & Paste

2009-03-17T00:36:00.009+02:00

Since I use VNC intensively, I needed to automaticly start VNC session when the Linux machine comes up, a lot of posts in the internet explains how to hack gdm, init.d services, rc.local, etc.. but it seems that VNC developers already thought about this and here is the simplest way:
1. Edit /etc/sysconfig/vncserver and include the line VNCSERVERS="sessionnumber:myusername"
For example:
VNCSERVERS="1:ali"
VNCSERVERARGS[1]="-geometry 1016x710 -nolisten tcp -nohttpd"
2. Enable vncserver on runlevel system services, run: chkconfig vncserver on

That's it, you can try to reboot your machine and check how VNC session is automatically up!

Tips:
o If you're having troubles to launch a graphical (kde/gnome) vnc session, you need to change your ~/.vnc/xstartup file, here is mine:
#!/bin/sh

# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 1024x768 -ls -title "$VNCDESKTOP Ali Ayoub Desktop" &
autocutsel &
gnome-session &
#startx &

o Copy & Paste troubleshooting:
Copy and paste feature may be problematic in VNC, a work around that worth checking is to run manually: vncconfig -iconic &
I tried to add this line to xstartup but it doesn't seem to solve the problem, I had to run it manually after the VNC session is open, and only then copy and paste between VNC session (Linux) and Windows work!

MyBookWorld Ed - overview and hacks

2008-12-20T00:46:00.009+02:00

I've just purchased a new Western Digital My Book World Edition 0.5 TB (500 GB), this piece of HD has 1GB Ethernet connection, it's capacity can be extended by a USB port.
The access to the remote HD is easy using NFS, few minutes later "The Hacking WD MyBook World Ed" website, these guys did a very nice job and documented all instructions required for hacking the MyBook World.

The MyBook World runs a Linux based Operating System (Daaa) on 2.6.x kernel, it has various capabilities and services which aren't enabled by WD.

It all start from enabling SSH on the device, and after that, the sky is the limit :)

Pros:
- Small (172x144x56mm) , nice design
- Low power
- Sophisticated system (It's Linux god damn it)
- 1 GB Ethernet Controller, 500GB capacity (there is also 1TB version, twice price)
- It's 24/7 powered on
- HD is expendable by USB port
- Price: 588 NIS

Cons:
- Speed: using scp 3.2Mb/s for read, 2.4Mb/s for write (I expected more than that)

So.. Let's install torrent downloader on it!
This hack installs torrent downloader called transmission on the MyBook world system with WEB interface, then you can upload torrent files to your MyBook World :)
It's pretty easy and recommended, the MyBook World will download as long as there is Internet connection, and all downloaded files are installed directly on its storage, you can follow up the download/upload process anytime from any internet browser from your LAN, I even check the status from safari from my iPhone :) exactly what I need.

Below a snapshot of the torrent downloader web interface:

iPhone MAC Spoofing

2008-12-04T18:59:00.017+02:00

I have suggested a way to spoof your MAC address on iPhone.
Here is a simpler way that makes use of BossPrefs for MAC spoofing.
1. If BossPrefs is not installed, install it via Cydia.
2. Lunch BossPrefs, click config, click add
3. Enter the following info:
Name: Mac Spoof
Start: ifconfig en0 ether FAKE_MAC (For example: ifconfig en0 ether 00:14:dd:11:02:79)
Stop: ifconfig en0 ether ORIG_MAC
Process: leave empty
Icon: leave empty
4. Click save

We're done :)
Each time you want to spoof your MAC, do it easily via BossPrefs.

Notes:
- MAC address for example: 00:14:dd:11:02:79
- ORIG_MAC = Your original mac address; from iPhone: go to settings, General, WiFi Address
- FAKE_MAC = Your fake mac address; from Windows: start, type cmd, type ipconfig -all, and examine the output for your wireless network connection MAC address
- This was tested on FW 2.2, it should work on all versions where BossPrefs is installed
- Sometimes, after you turn it "on", and then want to it turn "off", you'll find that it's already in "off" state, In this case turn it "on" then "off" again. Thanks for Anonymous for pointing this out :)

disable iPhone backup in iTunes

2008-09-09T12:44:00.006+03:00

If you're using iPhone FW 2.0.x you probably noticed that on (almost) each sync between your iPhone and iTunes a backup operation is performed, and it may take long time (for 100 apps, it may take more than 3 hours) and this is annoying feature for people who sync their iPhone frequently.

This application by Dennis Nederlof is very useful and does the trick:

netper netserver on Windows tip

2008-07-08T14:56:00.003+03:00

Q: I am running netserver on Windows (XP x64) and I am getting this error messaeg:
C:\>m:\mpi_db\svn.phoenix\trunk\scripts\netperfwin\x86_64\netserver.exe
netserver: fopen of debug file as new stdout failed!: The system cannot find the path specified.
What's wrong?
A: netserver need to open the file c:\\temp\\netperf.debug with write permission, so
Run: mkdir %HOMEDRIVER%/temp/
And make sure you can create files with write permission in it

Source: netserver.c
#ifndef DEBUG_LOG_FILE
#ifndef WIN32
#define DEBUG_LOG_FILE "/tmp/netperf.debug"
#else
#define DEBUG_LOG_FILE "c:\\temp\\netperf.debug"
#endif /* WIN32 */

Search for faces by Firefox/Google

2008-07-05T16:01:00.009+03:00

Recently, a friend of mine sent me a link of Google queries tips, I liked the one on how to make Google recognize faces for you, and below is how to make Firefox 3.0 make this easier:

1. Create new bookmark; select Bookmarks and right click on the drop down menu.

2. On the pop up window, enter:
Name: Google Search Faces
Location: http://images.google.com/images?q=%s&imgtype=face
Keyword: faces
Description: whatever u want

3. From now on, when you want to search for faces, on Firefox search bar type "faces name"
For example to search for Vin Diesel faces, type "faces diesel"

without this trick the results would be:

youtube video freezes after 2 seconds in Firefox

2008-06-19T01:06:00.003+03:00

I saw that many people hit this problem as I did, especially when trying to watch youtube video. There are a lot of suggested solutions in the web, I tried most of them, and here is the one which works:
It seems that there is a compatibility problem between Adobe Flash plugin and Firefox (verion 2.x and 3.0), downgrading your Flash plugin will solve the problem:
0. Shtdown FireFox and other programs that might be using Flash plugin
1. Uninstall your Adobe Flash plugin, for Windows users go to control panel, add/remove programs, and select Adobe Flash plugin, then uninstall it
2. Downgrade your plugin to version 9r45:
- Download it from Adobe website or from this direct link
3. Run Firefox and make sure that your 'new' flash plugin is ok, watch this talented violin player video for example :) if you could enjoy this 1 min 22 seconds video it means you got rid from 2 seconds Firefox freeze problem !!
4. I recommend disabling flash player update notification to avoid updating your player mistakly, click here and unslecet "notify me.." option

NOTES!
- You may try other solutions like killing Firefox, reinstalling the plugin, or changing Firefox version or settings, or even restarting your computer - all these solutions are temporary for a while, and the freeze problem will occur again within few hours.
- Remember to update you flash player once a new version which solves the problem is released (search the web)
- Use Firefox, be cool!

That's it.
Enjoy!

iPhone terminal (vt100) su root problem

2008-05-31T00:24:00.003+03:00

It took my some time to find a fix for this problem, this is why I am posting this;
For those who use the iPhone terminal, you may hit this problem on FW 1.1.3/4 where you cannot login as root.
When you open the terminal, you're automatically logged as 'mobile' user with limited privilege, to switch to root user run 'su root' and use 'alpine' password, however you may get the error message "incorrect password" this problem is fixed by:
1. Run Installer app and add the source "iphone.lenlolabs.com"
2. Install "BSD Subsystem 2.x SU Replacement"
3. Restart your iPhone

After this you can be root, remember "With great power comes great responsibility" !

HOWTO change iPhone MAC address!

2008-04-21T18:44:00.015+03:00

Update: I've published an easier way using BossPrefs

For those who need to spoof their MAC address in the iPhone, follow these instructions:
1. Install Term-vt100 on you iPhone (via the App installer & Conceited Software source, also available in cydia)
2. Open the terminal (default password is "alpine"), if it doesn't ask for password, run 'su' then type 'apline'
-- Do use local terminal rather than SSH since you're gonna change network configuration.
3. Run "ifconfig", and write down you original MAC address as appears in ifconfig output (see snapshot above)
4. Choose fake MAC address (for those who's trying to bypass MAC filtering mechanism, you need to find one, use your imagination.. or sneak to your friends laptop -- avoid MAC conflicts!)
5. Run the following commands on your iPhone
echo "ifconfig en0 ether ORIG_MAC

" > ./mac_orig.sh
echo "ifconfig en0 ether FAKE_MAC" > ./mac_fake.sh
chmod +x mac_fake.sh mac_orig.sh
6. We're done, to switch to the new MAC address:
- Run (from terminal) "./mac_fake.sh"
to switch back to your original MAC address:
- Run (from terminal) "./mac_orig.sh"

NOTE: your MAC is restored after iPhone restart
If you wish to make your fake MAC constant:
1. Run

(from terminal or ssh):

echo /var/root/mac_fake.sh >> /etc/rc.local

2. Run (from terminal or ssh):

chmod 755 /etc/rc.local
3. Restart your iphone

Happy hacking.

Herbert A. Millington
Chair - Search Committee
412A Clarkson Hall, Whitson University
College Hill, MA 34109

Dear Professor Millington,

Thank you for your letter of March 16. After careful consideration, I regret to inform you that I am unable to accept your refusal to offer me an assistant professor position in your department.

This year I have been particularly fortunate in receiving an unusually large number of rejection letters. With such a varied and promising field of candidates, it is impossible for me to accept all refusals.

Despite Whitson's outstanding qualifications and previous experience in rejecting applicants, I find that your rejection does not meet my needs at this time. Therefore, I will assume the position of assistant professor in your department this August. I look forward to seeing you then.

Best of luck in rejecting future applicants.

Sincerely,
Chris L. Jensen

احلام وجذور
هناك عند مدخل الاحلام، تنتظر العواصف فجوات ربما لم يكن بالاتساع فهمها او حتى رؤيتها.. وما اقصى ان تفاجئك عاصفه لم تتحضر لها!

ولكن من الغباء ان يصارع الاعرج عدوه بعكازه!
ومن الجبن ان تتراجع تاركا ذلك المدخل الرهيب هاربا..

وهناك وقد ربما يمكنك ان تفهم مدى جذورك.. فلجذر زهره تحتقر الشهره.

هي الحياه هكذا.. لحظات..لحظات تعيشها وتسكنها كأنها حياتك باكملها.
والجميل في تلك اللحظات بانك تتخذ قرارات بناءا على لحظات قد سكنتها وعشتها من قبل وها انت تعشقها او تحتقرها او حتى تحتقرها وتعشقها في الأن نفسه!
والاجمل والاذكى لو ادركت بان قرارك هذه اللحظه قد يبنى شليه قرارات في اللحظات التاليه! فيا ليت لو تعشق قرارك هذه اللحظه.

قراراتك هي جذورك..هي حياتك..هي انت.

فلو كانت قويه انت لست بحاجه بأن تكسر عكازك وانت ابدا لن تهرب..
ستقف شامخا فاتحا صدرك لكل عواصف هذه الارض..

تم هذا بناءا على ولا اشي. فشكرا جدا جزيلا

موسيقى النظرات تبث راحه وتوترا
وهدوء يقول ما لم تقل
الظلام حينها قنديل الطريق
وخطاك لا يسبقها تردد.. ولا تفكير..
دعه يقود اللحظات
فللجسد لغة
والعشق جسد
يعرف الطريق دون ان يالفها
بل هو الطريق

كانت لغتنا.. احترفتها حين خرست اهاتي,
تكلمت بها كلما اشتقتك,
احببت الوحده لاجلك
رسمتك وكنت لي وحدي
نتبادل النظرات الجامده ونصرخ صمتا,
ونستبدل البرد قبلاتا
اغمض عيناي كي لا يراك سواي
فلا محل بجزيرتي لسواك او سواي
احطها بحرا واضات بسماها شمسا لا تغيب,
ازهارها تفوح باسمائك..
جعلت كل شيء فيها يشبهك, الا الضباب..
ابى من ارضي ان ينسحب..
اتحبينني?

Only in Israel, you can find employers ask for waiters only after duty!!
Only in this country you need to know how to use M16 in order to serve food.

If it's age limitation; employer could simply say: waiters needed; must be 21 years old.

The lynx effect

It's also a name of a wild cat

But neither one of these definition would give you a hint what's the "lynx effect" :)
