“The new Facebook Messenger integration, which is the first new service to come out of Mozilla’s new Social API project, is optional and must be turned on by the user, according to a Nov. 20 post on The Mozilla Blog. So far, the Facebook integration is a preview into the fledgling service, and more capabilities and features will be added.”

From Wikipedia, the free encyclopedia
Super WiFi,or IEEE 802.22 and IEEE 802.11af as it’s Technically known, is a term coined by the United States Federal Communications Commission (FCC) to describe a wireless networking proposal which the FCC plans to use for the creation of longer-distance wireless internet. The use of the trademark “Wi-Fi” in the name has been criticized because it is not based on Wi-Fi technology or endorsed by the Wi-Fi Alliance.
Instead of using the 2.4 GHz radio frequency of Wi-Fi, the ‘Super Wi-Fi’ proposal uses the lower-frequency white spaces between television channel frequencies. These lower frequencies allow the signal to travel further and penetrate walls better than the higher frequencies previously used. The FCC’s plan is to allow those white space frequencies to be used for free, as happens with Wi-Fi and Bluetooth.

If you have the Windows firewall blocking all unauthorized outgoing connections, some Flash content doesn’t work properly.
- Start “Windows Firewall With Advanced Security” as an administrator
- Create a new Outbound Rule and allow the following program file: C:\Windows\SysWOW64\Macromed\Flash\FlashPlayerPlugin_11_3_300_257.exe
Filename may vary depending on Flash and Windows version.

c:\netsh firewall set logging droppedpackets = enable
Although the log file doesn’t include the name of the program that is trying to make an outbound connection, the log file can then be found at: %systemroot%\system32\LogFiles\Firewall\pfirewall.log

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.

[code]/set irc_join_delay 20[/code]
The default value is 2 seconds. 20 seconds should be okay in most cases.
If the IRC client supports server passwords, you can also identify automatically and more quickly by using YourUsername:YourPassword as your server password. (It is quicker then using the “/msg nickserv identity password” command so you should be identified by the time the auto-join happens).

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

Skype 18.104.22.168 beta uses pulseaudio as the default sound device, so you need to change the default sound device fo skype using a pulseaudio.
- Install pavucontrol if it’s not already installed
- Start pavucontrol
- Play a sound in the application where you need to change the default sound device.
- While the sound is playing, switch back to pavucontrol and change the sound device.
- that should be it.
I needed to set my Logitech Clearchat Wireless Headphones as the default sound device for Skype 22.214.171.124 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
Serial Device to
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
Turn off both
Hardware Flow Control and
Software Flow Control.
Modem and dialing menu, remove the
Init string and
Reset string completely if required.
- Save your new config
- start minicom
- more details
- Use one of the following commands:
||Tells about the command set available for this Watchport
||as described in this section
||Tells what kind of Watchport is connected.
||Gives the percentage relative humidity.
||Gives temperature in Celsius.
||Also gives temperature in Celsius.
||Gives temperature in Fahrenheit.
||Repeats the TF command every 3-4 seconds until the next keystroke. Appending + also works with the TC and H commands
||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.
Download Watchport’s manual
Now all I need is a perl script to automate the posting of these values to twitter?

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.
- Double click the speaker in the System Tray
- Click Options – Properties – Playback – Check Microphone – Click OK
- 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.
