Started over 100 years ago by Nikola Tesla, the concept of transmitting electricity wirelessly is catching on fast. The dominant player is intel, but smaller companies such as Wild Charge prove that there is something substantive and viable making the recharging of devices easier and more convenient. While Wild Charge does not transmit energy wireless it does substantially simplify the recharging process.
Resonant inductance can sync magnetic fields in such a way that power apparently flows, or jumps, empty space. Based on the fundamental properties of inductors and magnetic fields devices that require recharging will not require a direct connection to draw power. A rechargeable device can be situated nearby the power source, and without a wired connection can successfully draw enough energy to recharge the device.
Tesla was a big dreamer and envisioned this type of technology transmitting energy all over the world. He wanted to sync the Earth’s magnetic field with devices; now thats big. Without a doubt he was ahead of his time, and there were and are definitely effects on biological systems. The extend that genetic, and molecular damage can occur is unclear, but without a doubt the concent originated by Tesla is effective at transmitting energy wirelessly.

For a long time I was annoyed by having to input my routers WPA PSK passcode each time I booted. At minimum I would have to unlock the keyring containing the passcode, even after checking the button to automatically unlock it upon login. These issues are resolved in the new release of Ubuntu. The new version has definitely provided many upgrades to increase stability, and further polish this awesome Linux distribution.
Also regarding Broadcom wireless card support, ndiswrapper is no longer needed. The new B43 driver uses the well known fwcutter (firmware cutter) very effectively. The driver allows full speed data transmission that was typically only achievable using ndiswrapper. Now, right out of the box Ubuntu is fully compatible with Nvidia graphics cards, and basically all wireless cards. With each new release I see less reasons to stick with Windows

I’ve experience problems backing up my web server, via scp, over my wireless connection. To resolve this I simply connected my computer via ethernet, rather than wireless. It seems that the wireless was causing the scp to stall whereas via a direct ethernet connection everything goes smoothly.

When you enter a router WEP, or PSK, you can create a keyring password, so that your router password is automatically store and retreived when necessary. The only drawback is that you will have to enter your keyring password each time you login. To automatically use your GDM login password as your keyring password you can do the following:
sudo apt-get install libpam-keyring
Then edit your GDM configuration file:
sudo gedit /etc/pam.d/gdm
Your going to want to add at the bottom of the file:
@include common-pamkeyring
Then delete your existing keyrings. The next time you login, you are going to have to re-enter your rother WPA/PSK password, and when you set the keyring password, just use the same password that you use to login to your GDM account. Now when you login via the GDM you will automatically unlock your keyring and connect to the wireless network.
Note that if your have set up automatic GDM login, you may have to disable it, setup the wireless, then re-enable it. Otherwise cheers to automatic login
