1. set up /etc/network/interfaces
2. set up /etc/wpa_supplicant/wpa_supplicant.conf
3. set up driver according to section... Installing the rtl8188eu based wifi adaptor driver for Raspbian.

5. reboot


P.S. to force connecting by commands at rc.local,
add following to /etc/rc.local, without modifying /etc/networks/interfaces or wpa_conf files

Step 0: get a network cable

In order to solve this issue you will need Internet. Get a network cable which you can physically connect to your router. Once you have Internet access the following steps are much easier to follow.

Step 1: make it easy to open terminal window in a specific folder location

This step is important since it makes several other steps easier to manage.

The instructions on how to do it are given here. You simply need to open a terminal window (press CTRL+ALT+T), and type:
sudo apt-get install nautilus-open-terminal

From now on, whenever you want to open a new terminal window in a specific folder – you simply right-click that folder (from the folder which is a level above it) and choose “Open in Terminal”

Step 2: Download the latest edimx drivers
http://www.realtek.com.tw/downloads/...oads=true#2742

Step 3: Install the new driver

Go to the download folder and open (using right click, if you followed step 0) the terminal for the folder “RTL8192CU_8188CUS_8188CE-VAU_linux_v3.1.2590.20110922″. Then run:

sudo bash install.sh

(note 1: it will ask for your user’s password – as will any command which is using the sudo = super user do prefix)
(note 2: in order to paste in the terminal, use ctrl+shift+v instead of just ctrl+v as is in the GUI and other editors)

Step 4: blacklist the old driver

Next, we want to edit /etc/modprobe.d/blacklist.conf Getting there using the GUI wouldn’t work, because ubuntu wouldn’t let us save the changes we will make. Instead, just open the terminal and type:
sudo gedit /etc/modprobe.d/blacklist.conf

Go to the end of the file and add the line:

blacklist rtl8192cu

(thanks goes to icracked for the advise)

Step 5: remove and re-insert the network USB (and reboot)

Once done – I was finally able to see and connect to my home Internet network.

At this point, some people also said reboot helped, so if you got this far, why not do that too…

Studied bongofish website, corresponding WACOM model# :  SU-025-C02
there are 2 types for the pins, 10 or 14 pins.

For 14 pins, identify gnd(P1 or P2), vcc(P13), usb data+(P4), usb data -(P3).
For 10 pins, identify gnd(P6), vcc(P1), rxd tab->host @19200baud (P2), txd tab<-host (P3)
**txd description is different in bongofish website, but i believe this is the correct way.

[tutorialspoint] Python Extension Programming with C

http://www.tutorialspoint.com/python/python_further_extensions.htm


For your first look at a Python extension module, you'll be grouping your code into four parts:

• The header file Python.h.
• The C functions you want to expose as the interface from your module.
• A table mapping the names of your functions as Python developers will see them to C functions inside the extension module.
• An initialization function

Structure

#include <Python.h>

static PyObject *module_func(PyObject *self, PyObject *args) {
   /* Do your stuff here. */
   Py_RETURN_NONE;
}

static PyMethodDef module_methods[] = {
   { "func", (PyCFunction)module_func, METH_NOARGS, NULL },
   { NULL, NULL, 0, NULL }
};

PyMODINIT_FUNC initModule() {
   Py_InitModule3(func, module_methods, "docstring...");
}

Example

#include <Python.h>

static PyObject* helloworld(PyObject* self)
{
    return Py_BuildValue("s", "Hello, Python extensions!!");
}

static char helloworld_docs[] =
    "helloworld( ): Any message you want to put here!!\n";

static PyMethodDef helloworld_funcs[] = {
    {"helloworld", (PyCFunction)helloworld, 
     METH_NOARGS, helloworld_docs},
    {NULL}
};

void inithelloworld(void)
{
    Py_InitModule3("helloworld", helloworld_funcs,
                   "Extension module example!");
}

Usage
setup.py

from distutils.core import setup, Extension
setup(name='helloworld', version='1.0',  \
      ext_modules=[Extension('helloworld', ['hello.c'])])

$ python setup.py install

Usage II

#!/usr/bin/python
import helloworld

#cat /etc/rc.d/init.d/README; says use systemctl

However, making rc.local under rc.d/ directory should still work.

#touch /etc/rc.d/rc.local

[synergy] Share one set of mouse and keyboard over multiple computers

www.yodi.sg/setup-synergy-server-and-client-multiple-screen-fedora-core-17/

My setup involves a main box (2 monitors)- then my laptop (3rd external monitor) plugged into one router.

Since my desk space is limited, sharing inputs across different system comes handy.

Using Synergy, KVM switch like environment can be set up over the network.

Main box has fedora; 192.168.0.1 (will be server)
Laptop has ubuntu 12.04.4; 192.168.0.2 (will be client)

1. Install synergy
sudo yum install synergy
sudo apt-get install synergy

2. Setup server (on fedora 19)
sudo nano /etc/sysconfig/network #give two computers different hostname
sudo nano /etc/hosts #now there is no need to type ip every time

#synergy hostname setup
192.168.0.1 master0
192.168.0.2 node0
#Ctrl-X save-Y and exit

Save everything and restart or
sudo service network restart

2.1 configure synergy
sudo touch /etc/synergy.conf
sudo nano /etc/synergy.conf

section: screens
    master0:
    node0:
end

section: aliases
    master0:
        localhost.localdomain
    node0:
        192.168.0.2
end

section: links
    master0:
        right = node0
    node0:
        left = master0
end

#save and exit

2.2 run the server
synergys -f --config /etc/synergy.conf
#put it in a boot script without -f, so it can run as a daemon

3. run the client
synergyc -n node0 master0
#put this line in a startup application or /etc/init.d/rc.local
#so it will connect to the server automatically every boot up
#this line in a boot script doesn't work for 1.4+, taskbar is not available error
#will work with synergy 1.3.8, protocol version 1.3

Reinstalling grub2 after installing an OS on a new partition

On my test system there is linux mint 16, and just finished installing kali.

I made a mistake of overwriting grub on /dev/sda and this has inverted boot order.

Boot order can be changed easily, but instead I want the original boot loader list provided by linux mint.

https://help.ubuntu.com/community/Grub2/Installing

So, boot into the mint 16, I just want to overwrite everything for simplicity.

$sudo grub-install /dev/sda

/usr/sbin/grub-bios-setup: warning: Sector 50 is already in use by the program 'FlexNet'; avoiding it.
This software may cause boot or other problems in future.
Please ask its authors not to store data in the boot track.
Installation finished. No error reported.

$sudo reboot

Now on the boot list, there is no kali install, but the original list shows.

On booting into mint,

$sudo update-grub
$sudo reboot


Now kali shows up as 'Debian GNU/Linux (Kali Linux 1.0.6)'

1. burn dmg imagefile from retail cd on USB
$dmg2img snowleopard.dmg snowleopard.img
$hexdump -C snowleopard.img | grep "48 2b 00 04"
(convert 00000400_hex into decimal = 1024, then subtract 1024 from this decimal number to calculate offset, which is 000000 in this case) 
$sudo losetup -o 000000 /dev/loop0 snowleopard.img
$sudo mkdir /media/userID/test
$sudo mount -t hfsplus /dev/loop0 /media/userID/test/

prepare a 8GB+ usb drive, format using gparted, give MBR scheme, give 8GB partition for image formatted as hfs+, mount at /media/userID/imgTarget/

$sudo cp -r /media/userID/test/* /media/userID/imgTarget/

2. sudo cat /path/to/source/sda2.ext4-ptcl-image.gz.* | sudo gzip -d -c | sudo partclone.restore -C -s - -o /path/to/target/sda2.img

3. sudo e2fsck -f partclone_extfs.img

sudo cat sda2.ext4-ptcl-image.gz.* | sudo gzip -d -c | sudo partclone.restore -C -s - -o /path/to/target/sda2.img

3. mount

sudo mount -o loop -t ext4 /path/to/source/sda2.img /media/name/target/folder/

How to open and screw back in macbook pro properly

http://forums.macrumors.com/showthread.php?t=1263708

Screwing back the bottom panel of macbook pro after RAM/HDD upgrade or replacement.

The screws can stick out and not go in all the way because six screws not along the hinge edge goes in angle.

http://km.support.apple.com/library/APPLE/APPLECARE_ALLGEOS/HT1270/HT1270_1a-mbp_13-remove_back_screws-001-en.png

Start from left top corner, then right bottom corner, going clockwise until finished.

Tightening them without making such 'star patter' may misalign the panel and screws could stick out.

instructions are right on the aokp platform manifest page-

Init repo only for a particular device :
$ repo init -u https://github.com/AOKP/platform_manifest.git -b jb-mr2 -g all,-notdefault,<devicename>,<vendorname>

for example, to init only trees needed to build mako :
$ repo init -u https://github.com/AOKP/platform_manifest.git -b jb-mr2 -g all,-notdefault,mako,lge
