As a 400 MHz Linux system with 32 MB of RAM, using only ~100 mA @ 3.3 V, the possibilities are endless!

This post is written with the intention of exposing not only the exploits which will allow you to root (or jailbreak) the device, but also the process of discovering and exploiting bugs, some of which are a dead end, while others lead to the holy root B-)

As he suspected that some kind of Linux was running on it, he began to see if he could get a root access on it… and succeeded.

It should be simple, but I ran into a number of errors.

First I got stuck on libtool: line 990: g++: command not found. It turns out I needed to install g++ using:

yum install gcc-c++

Then I got stuck on this one:

platform.h:110:2: error: #error "Can not compile without isnan function or macro
[...]
"Coordinate.inl:38: error: ‘ISNAN’ was not declared in this scope

The author of this page faced the problem, but the real insight came from this bug report on an unrelated project:

In these versions of g++ isnan is defined as a macro in <math.h> unless is included, in which case std::isnan() is defined instead.

And so I tried replacing #include <math.h> with #include <cmath> in include/geos/platform.h. Amazingly, that worked.

According to Groklaw, the long running battle between SCO and Novell may finally be over. The Judge ruled that SCO, the company that claimed Linux infringed on it’s IP and sued everybody in sight, never did own any rights to Unix in the first place, and has ordered the company to pay millions. Novell and others are unlikely to ever see much of that, though, as SCO is in bankruptcy.

Need JSON? I did. The solution is easy: yum install php-devel<br /> pecl install json The pecl install failed when it hit an 8MB memory limit, and I was clueless about how to fix it until I learned that the pecl installer ignores the php.ini. Turns out the best solution is to use the pear installer (which does follow php.ini settings): pear install pecl/json Installing MySQL with YUM how to install and configure MySQL database server yum, mysql, linux, yellow dog updater modified » about 100 words CentOS 5 Released At work I use Red Hat Enterprise Linux, but my personal stuff is served from machines running CentOS.

As Dell’s sales slump and stock remains flat, the famously unimaginative company is trying to tap into the Mob for ideas about what new shade of grey to deliver its hardware in next. And what did the Dell IdeaStorm mob say? “Give us Linux!” “Give Us OpenOffice.” And how did Dell respond? “No. No. And, No.” John Naughton reports on the story for The Guardian, explaining: more than 85,000 people took the trouble to register with IdeaStorm in order to tell Mr Dell that they wanted him to ship his computers with Linux pre-installed. Moreover, 55,000 revealed that they would like the free open-source office software suite, OpenOffice, pre-installed on their shiny new Dell machines. And all Michael Dell could say was that there are too many variants of Linux. Of course that doesn’t explain why the company, who’s biggest contribution to the technology world was an online store that allowed customers to chose computer configurations from a dizzying array of options, doesn’t simply allow customers to buy their PCs with no software at all.
