[HAIFUX LECTURE] Mesh Networks:Hacking the T3lc0 Model by Amir Sagie

[Eli Billauer]

On Monday, August 29th (TOMORROW), at 18:30, Haifux will gather to hear 
Amir Sagie talk about



Mesh Networks:Hacking the T3lc0 Model


Abstract


Want to build your own Telco? You'll probable need mesh power. Avoid 
past mistakes by learning about the history of mesh networks, hear how 
the first wi-fi router was liberated and be sure to checkout what we're 
doing in project Arig ( http://arig.org.il), here in Israel! Be sure to 
attend the router emancipation party afterwords: bring your wi-fi router 
and wash away all it's sins by flashing it with a FOSS OS such as 
OpenWRT. Complete redemption guaranteed.





We meet in Taub (CS Faculty) building, room 6. For instructions see: 
http://www.haifux.org/where.html


Attendance is free, and you are all invited!


Future Haifux talks include:

12/9/2011 Wiki-workshop by Tomer Ashur

26/9/2011 Deconstructing Amazon EC2 Spot Instance Pricing by Orna Agmon 
Ben-Yehuda


10/10/2011 How to Participate in the Linux Kernel Development (and Why)

Different security models. For obvious reasons, if the programmers are
not fools, you have to type an unlock password before the device
activates the data pins and you can dump/upload data/firmware. I have
difficulty imagining an on-screen keyboard that fits into tiny boot
areas of the phone. But, I admit, I've already seen one, in a Toshiba
convertible tablet-laptop POST sequence.

Fine with me.

We won't see a free, open OS on some manufacturer's phone because ATM,
there is no incentive to that manufacturer to give you a free, open OS
on your phone, other than cutting on the OS development costs. But then,
the OS usually comes from another company that fits the OS development
bill and expects something in return. Something that's more than
one-time fraction of the device's price.

I don't see how having or not having a keyboard has anything to do with
being able to revive a bricked unit.
The SheevaPlug has no keyboard, yet it's mini-USB connection that can drive
a JTAG chain to reprogram the internal flash regardless of the unit state.

The N950 is not available for sale.
There were 250 units available on a long-term loan to qualified developers,
and then 100 more were made available on the same requirements via maemo.orgor
meego.org or something like that.
You just can't buy it.
And even if you could, it's software would probably be in a worse state than
the N900's.

Personally, I have an N900 and I don't see anything that can replace it at
the moment.
I just hope that eventually we would see Meego on someone's phone.
If it would break down I would look for a 2nd hand one.

btw, is there a distribution for people who want to take an android and make
it gnuish ? one with available libraries for other software.
