Google Index removal, Long Distance WiFi for Costa Rica

It is hard to find time to post, even harder to think what is something I can release that won't be bad for me in the future or lead to someone pwning me. Some people won't even use their name on the internet for fear that something they write could someday be used against them. On that subject I got a call yesterday from an old friend about removing his wife's name from Google, seems like she was associated to the Orange Team in some post at UT SW that got blogged and I have no idea why this was so bad, but so far he managed to get the blogger to remove the name, but Google had not crawled the page again yet, the last time they did was June, and since it is July he was getting very antsy about it. So after an hour of googling I found how to do it, Webpage removal request tool.

I also got a call from Costa Rica about getting satillite internet, seems lame so I asked how far from wired internet, 4 Km, hmmm... NanoStation2 was my answer to that one. I then went to look for my content in http://socalwifi.net/ and found it down :( Seems there are attacks on the server and the admin is trying to resolve the DOS. Intel has an interesting claim of more then 60 miles on WiFi. But a Loco is probably enough for 4 miles, so why keep looking.

So I skype this all back to Mark, but he has been MIA since I tried to get this info back to him, geez:
This guys are pretty awsome: http://www.wlanparts.com/ they used to have monthly meetings about WiFi.

We're going to try something new tonight, and plan on streaming this
presentation live. Thanks to Israel's kind offer to attempt this
previously unheard of technological feat, if you really can't make it
to OC you should be able to watch this presentation on
http://www.ustream.tv/channel/uuasc . Since this is our first attempt
at this, you should probably attend in person if possible. If you
watch it on the stream, please post some feedback to the mailing list,
especially if you'd like to see us continue to do this.


Tonight's meeting in Orange County will feature two individuals from
Engineers Without Borders: Orange County Professionals (EWB-OC);
Israel Lopez & Chris Healy will be speaking to us about their recent
trip to Honduras where they are setting up a wireless network for an
educational system called "Olancho Aid". They will give an overview of
the project and explain how they will be using 802.11a/g to distribute
the internet access to two other schools, how Linux is involved in the
management of the network, and how Linux might be used on the student
desktop. Also, they have implemented a small Asterisk server to save
the school communication costs between buildings, a real savings of
over $200 USD a month, where the average salary is $400 USD.

They intend to use their experience with Olancho Aid as a sustainable
technology model that can be 'copied-and-pasted' to other education
systems in Honduras. Once a successful implementation is in place,
they hope to build up the local community's technology skill-set as a
way to uplift the community out of poverty.

Israel Lopez owns a small webhosting business; Sandbox IT Solutions
LLC, he also is the Vice President of Internal Affairs for EWB-OC, and
is the Technology Lead for the Honduras project.

Thank you for attending the meeting tonight online & in person. I have to apologize for the online broadcast, the technology & setup was there, the bandwidth was not. So we could use some more suggestions on how to get better bandwidth & UUASC-OC next time. We hope to continue these broadcasts, as we will be getting better and better at putting them on.

As promised tonight the slides are available here: http://ilopez.com/temp/UUASC-Talk.pdf
Including a video short summary that was missed in the presentation: http://vimeo.com/5587796. I will have the whole presentation uploaded to Vimeo soon, it is being transcoded from AVCHD into WMV HD (720p). Hope to get that converted successfully and uploaded soon.

I hope everyone had a great time, hope to give you guys an update after we get back in December!

Again our website is http://ewb-oc.org/olancho and if you have any questions feel free to email me directly.
