At page 14 of Google’s results for keywords “android touchpad”, they list 447,000 results and at page 15 it drops to 144 results. Inflated result counts?

LifeNet is a WiFi-based data communication solution designed for post-disaster scenarios. It is open-source software and designed to run on consumer devices such as laptops, smart-phones and wireless routers. LifeNet is an ad hoc networking platform over which critical software applications including chat, voice messaging, MIS systems, etc. can be easily deployed. LifeNet can grow incrementally, is robust to node failures and enables Internet sharing. A novel multi-path ad-hoc routing protocol present at its core, enables LifeNet to achieve these features.

Set up 4 to 6 passwords:
one for all the low-security sites,
another for any site that has your credit card number,
another for social networking,
another for email,
another for work,
and the most secure for your banking sites. Sleep better.

Keep them on a piece of paper somewhere safe like your wallet.

These rules are not always possible, but they help reduce the numbers of passwords while staying fairly secure.

I tried to add a 2nd google account on my Android phone and got the following error even if I connected using wifi: “can’t establish a reliable data connection to the server”.

The workaround that I found is to register your Google account through your YouTube app, after which your gmail for that account will be available for syncing.

/set irc_join_delay 20

The default value is 2 seconds. 20 seconds should be okay in most cases.

I was trying to do a DHCP reservation but D-Link’s DIR-615 wouldn’t accept my phone’s MAC address because it didn’t start with “00″. Although the firmware was fixed since version 3.11NA (download update), here is what I did to work around this problem:

1. Using Firebug in Firefox, set a break-point at line 420 in file public.js
2. Edit temp_mac’s array value at position 0 from “fc” to “00″ (“fc” or anything else)
3. Continue execution of script

Using Firefox and Adblock Plus, you can block some unwanted “features” of Facebook: http://blog.makezine.com/archive/2010/05/how-to_avoid_facebook_malware.html. For example, it should prevent Facebook from sharing information with other websites.

Or if you want, you can completely delete your account, thanks to the The Consumerist. You could also just deactivate your account if you plan on re-using it.

To be able to access my Adsense account, I had to add the following exception filter in Adblock plus:

Skype 2.1.0.47 beta uses pulseaudio as the default sound device, so you need to change the default sound device fo skype using a pulseaudio.

1. Install pavucontrol if it’s not already installed
2. Start pavucontrol
3. Play a sound in the application where you need to change the default sound device.
4. While the sound is playing, switch back to pavucontrol and change the sound device.
5. that should be it.

I needed to set my Logitech Clearchat Wireless Headphones as the default sound device for Skype 2.1.0.47 beta in Ubuntu Karmic Alpha (pavucontrol was not installed).

Using Digi Watchport/H USB Serial Humidity/Temperature Sensor in Linux

Ubuntu 9.04 has everything you need except for minicom. So all I had to do was to:

• plug it in

  dmesg should get you the following output:

  usb 2-9: new full speed USB device using ohci_hcd and address 50
usb 2-9: configuration #1 chosen from 1 choice
io_ti 2-9:1.0: Edgeport TI 1 port adapter converter detected
usb 2-9: Edgeport TI 1 port adapter converter now attached to ttyUSB0

• Install minicom: sudo apt-get install minicom
• Edit minicom settings: ~$ minicom -s

  1. Change the Serial Device to /dev/ttyUSB0

  2. Change the Bps/Par/Bits field to 9600 8N1, (9600 baud, 8 bits, no parity, 1 stop bit). These are the default settings used by the Linux kernel; they can, if necessary, be overridden from the kernel command line by adding extra parameters to the console= option. See kernel-parameters.txt and serial-console.txt.

  3. Turn off both Hardware Flow Control and Software Flow Control.

  4. In the Modem and dialing menu, remove the Init string and Reset string completely if required.

  5. Save your new config
  6. start minicom
  7. more details
• Use one of the following commands:
  

  Command	Description	Return Value
  ?<CR>	Tells about the command set available for this Watchport	as described in this section
  I<CR>	Tells what kind of Watchport is connected.	Watchport/H<CR>
  H<CR>	Gives the percentage relative humidity.	38%<CR>
  T<CR>	Gives temperature in Celsius.	+22.2500C<CR>
  TC<CR>	Also gives temperature in Celsius.	+22.2500C<CR>
  TF<CR>	Gives temperature in Fahrenheit.	+72.0000F<CR>
  TF+<CR>	Repeats the TF command every 3-4 seconds until the next keystroke. Appending + also works with the TC and H commands	+72.0000F<CR>
  L4<CR>	Adjusts the slew rate of the data line. When “L” is followed by a numeric value, 1 through 8, Watchport responds with OK. Other values return Invalid Command. The default setting is 4. Adjust the parameter until the data transmission becomes error-free. The setting remains in effect until the Watchport is power-cycled.	OK

Download Watchport’s manual

Now all I need is a perl script to automate the posting of these values to twitter?

I tried many other add-ons and extensions, but these are the ones I can’t live without:

1. Adblock Plus
2. No Script
3. Firebug (mostly for web development)

Bonus:

1. ShareMeNot
2. HTTPS Everywhere

First, download and install Audacity.

Then, to be able to record both the microphone input and the sound card output at the same time using Audacity, you have to un-mute the microphone playback in the Volume control.

1. Double click the speaker in the System Tray
2. Click Options – Properties – Playback – Check Microphone – Click OK
3. Un-check the microphones mute and raise the volume

You should now be able to hear yourself in the speakers or earphone when you talk in the microphone and also be able to record the output (person you called) and the input (you) in Audacity. Select Stereo Mix on Audacity’s Mixer Toolbar and hit Record.
