Nseries Nokia N810

I’ve already got the N810, so far I’ve got to say that it’s an awesome device, it’s way smaller than I thought it would be. I had to flash the N810 using the lastest firmware in order to install some applications such as Skype. I was a bit scared of doing it because I had some issues last time I flashed my cell phone, a Sony Ericcson W810i, I fuxored it although I was using Sony’s Official tool to update it, I was unable to use it for a weeks, the time it took me to do read about flashing with some 3rd party tools.

I’ve got the scratchbox environment running, I had some issues installing it on Ubuntu Hardy, following some advices from qwerty12 on ITT solved everything and allowed me to get the Maemo SDK running on lastest Ubuntu.

I had to disable vdso by adding vdso=0 to the kernel line on /boot/grub/menu.lst file. The second problem is related to a memory protection that got enabled on lastest kernel, you need to edit /etc/sysctl.conf and change: vm.mmap_min_addr = 65536 to: vm.mmap_min_addr = 4096.

I’ve already installed the following apps:

Canola / Mplayer
FBReader / Evince / Xournal
MaemoFTP / rdesktop / openssh
Duke3D / LxDoom / Quake / iNES
Pidgin / XChat / Skype

I was looking for a torrent client, found transmission for maemo, but it was not working very well, it was pausing itself after a while, so with my sbox installation, compiled libtorrent and rtorrent from debian’s repository, and installed on n810 with dpkg, it works like a charm.

I’ve been wondering if I should get a Nokia N810. I have already installed the Maemo SDK, and got some demos running on my box. I will keep checking the SDK this weekend, if things goes smooth, I’ll probably buy it next week, it’ll cost me around 620 USD, 200 dollars more than Amazon’s price, sucks, but that’s what happens when companies like Nokia don’t bring their products into ‘third world countries’. Should I consider another device?

Security Bookmarklets

I took a couple of days from my school vacation to write 3 bookmarklets that will help me when auditing web sites, I’d like to share them here because I know that they’ll help some of my friends, and probably one of the two readers of this blog.

Text2SQLChar Converts an string into a CHAR() mysql, usefull when magic_quotes is on.
SQLIncrement Increments automatically the number of columns of the injected select query.
SQLDecrement Decrements automatically the number of columns of the injected select query.
Increment Allows you to navigate up html files or images that have a number in them.
Decrement Allows you to navigate down html files or images that have a number in them.
base64 Firefox only, base64 with no padding

I wrote the first 3 of them, I’m not javascript god, so they need to get improved, I’ll try to make them shorter, and follow a couple of suggestion from bookmarklets.com. The two others come from RSnake’ bookmarklet collection, where I fixed a detail, it was not decoding the URL before using it, so if the url contained an escaped value at the end of the url like %20, it would modify it and change it to %21. I’ll keep this post updated whenever I find or write a new security-related bookmarklet. As another issue, I noticed that the site looks ugly on low resolution systems, so I’ll try to get a new theme to fix that on a couple of days and update the wordpress version.
