Good Free screen video capture / record, works under Vista

A good screen capture / record to video FREE program, directly from Microsoft, is called CommunityClips. It works for Windows XP and Vista. You an download it for FREE at

command line email client / mailer for gmail

Two programs:

1. SendEmail: http://caspian.dotconf.net/menu/Software/SendEmail/
2. smtp-cli: http://www.logix.cz/michal/devel/smtp-cli/

I tried SendEmail and it worked fine with gmail TLS SMTP.

The smtp-cli seems to have more features, which also means more complex. :-)

Both programs are written in Perl.

Brother MFC-495CW Inkjet Color

is a good PDF scanner. It scans to USB drive directly without PC.

It also has WiFi and Ethernet connection.

Add color to your linux console program

You can add color to your linux console print outs, such as usage.


#define CSI "\x1B\x5B"
main(){
printf("%s1;31m This is color text %s0m\n",CSI,CSI);
}

shell:
red text:
printf "\x1b\x5b1;31m Ignoring callcatcher \x1b\x5b0m\n";

green text:
printf "\x1b\x5b2;31m Ignoring callcatcher \x1b\x5b0m\n";

Details:
\x1B is Escape Char, \x5B is '['. They form the control string indicator.

1;31 are two commands
1 means bold color
31-37 are the colors

m: set display attributes command

0m: reset to normal display
color code list:

   Black      0;30       Dark Gray    1;30
  Red        0;31       Bold Red     1;31
  Green      0;32       Bold Green   1;32

Unofficial Smartq V5/V7 Linux Development Guide

This is a backup of the original doc at: http://docs.google.com/View?id=ddtx8wkh_18g39zskpm

Unofficial Smartq V5/V7 Linux Development Guide

This guide describes how to compile your own linux kernel and how to create SmartqV firmware image for flashing the V5 or V7.
You need a working linux host for development, I'm using Ubuntu.

1. Download the SmartqV SDK: http://rghost.net/980682
2. Extract SDK to your working directory: tar -xvf SmartqV_SDK.tar.gz
3. Install ARM toolchain:

• Extract armv6_codesourcery.tar.bz2 file into /opt directory: tar –xvf armv6_codesourcery.tar.bz2
• You should see /opt/armv6/... directory created.

4. Go back to SmartqV_SDK directory and extract the kernel:

• tar -xvf mer-smartq-mer-smartq-kernel-smartqv.tar.gz
• You can always download the latest kernel from: http://gitorious.org/mer-smartq/mer-smartq-kernel/commits/smartqv

5. Extract fw-utils:

• tar -xvf fw-utils.tar.bz2

6. Compiling the kernel:

• cd mer-smartq-mer-smartq-kernel

• Create default configuration: make SmartV7_defconfig for V7 or make SmartV5_defconfig for V5.
• Run ./make_zImage_rootfs.sh and you can find a file named linux.rom under ../fw-utils directory.
• make modules && make modules_install INSTALL_MOD_PATH=`pwd`/module-collection
  This pulls the generated modules into the ./module-collection directory, which can then be easily transferred with the kernel.

7. Creating firmware image:
• cd ../fw-utils
  
• For V7: ./compress.v tcboot.V7 linux.rom 0 && mv SmartQV5 SmartQV7
• For V5: ./compress.v tcboot.V5 linux.rom 0. The tcboot.V5 is not included in SDK, but you can extract it from official V5 image (see below).
  
• This will create SmartQV5 or SmartQV7 firmware image.
  

8. Copy the image to SD card and flash as usual.
9. Notes: The firmware image will update only the bootloader and kernel image.
   You can create a full image including rootfs and homefs using compress.v utility.
   Use uncompress utility to extract newest bootloader from official firmware. Extracted files saved in /tmp directory.

Enjoy!

pause/resume a linux process

To pause:

kill -STOP pid

To Resume:

kill -CONT pid

Works perfectly.

Simple NAT for Internet sharing

You need a Linux machine (or virtual machine running Linux, or Colinux) to do this:

#enable routing
echo 1 > /proc/sys/net/ipv4/ip_forward

#flush iptable
iptables -t nat -F

#enable DNAT (also known as IP masquerading)
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

#enable port forwarding
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 2401 -j DNAT --to 192.168.16.66:2401
iptables -t nat -A PREROUTING -i eth1 -p ALL --dport 82:88 -j DNAT --to 192.168.16.66:5000:5006
