Remind your visions of life with a digital photo frame

i've read books about different subjects like management and other theoretical books. All these books have one thing in common ... they all had a shema to remember and to use it as a tool. unfortunately i forget these schema's.

But my idea is to buy a digital photo frame and put the schema's as photo on this photo frame so i will see the shema's between the nice pictures of me.

scan wifi in the neighborhood

inSSider is a Netstumbler alternative.
Both of the applications use your Wireless Network adapter to scan all the Access Points in your neighborhood. When you experiencing latency on you wifi you use these tools to see what channels are used in the neighborhood. Try to find a channel that is not used or selectt one that is used by the access points far away(week signal)....

You can also use these applications to align antenna's.

Also Xirrus Wi-Fi Inspector  is such an application. (didnt test it)

i lost the link to the original webpage where i found this.
but it works ....

If you want to deploy sms for all your users use an smtp2sms gateway
there are plenty on the internet

i did a setup with Network SMS Gateway and took about 5 minutes

enjoy

polarization of wireless antenna's

When you install a wireless bridge you have to recognize the importance of the antenna polarization

See this and read about it on wikipedia

when you understand this, you have also a good idea on how to align wifi antenna's.
