Jailbreaking iOS4, the good, the bad and the ugly
Finally after waiting, and waiting the expected jailbreak for iOS4 came, the problem was I had a 3.1.3 “spirited” iPhone, so, the pwned version wont work for me. But thanx to @comex (et al) the great jailbreakme came, and I can join the iOS4 party.
The good:
Fast, I can’t believe its my old 3GS, is blazing fast, even with some “background jobs” its faster than 3.1.3. Another good things are folders, I used to have about 6 pages of apps, now I only had 2
The bad:
I can’t get to enable the “tethering” option on preferences, you can use the program tether (I kind of dislike it because its actually a socks proxy, not a NAT or something more native), or you can use MyWi4 , I used to like this on 3.1.3 but 2 things made me think about it, 1. you can not enable bluetooth tethering anymore, you can do USB tethering and wifi, but for example for my linux laptop I can no longer use bluetooth 
, 2. When you install MyWi4 it depends on a package mobilesubstrate, and this breaks a lot of things (and I’m not blaming anyone, I’m just saying this breaks things), for example, the “always on” functionality on skype, no longer works. check update, this is now working
Update: ( http://twitter.com/saurik/status/20294560499 )
The ugly:
I really hate that even applications that system preferences stays working on background, I might be wrong here (can be only showing the icon for example), but almost every app stays on this “taskbar” (the one you get when you doble click on the home button), and yes, the battery suffers even with only the skype running.
Well, anyway, I can’t go back , so I hope the hacking team can get the tether toggle enabled again. Consider this post a big thanks to the jailbreak team

07.31.10Playing with geektool (first the lyrics)
I always work with music, and I sometimes like to sing, so I want to see the lyrics of the current song, without opening itunes, and then the properties, so I use the Geektool project (a little old, but it works wih 64bits kernel), this app, will enable you to run commands and put the output on the wallpaper, you can see a lot cool screenshots on the developer site.
I will stick on the basics, I only want my lyrics (and some ps ax info).
So this scripts will help you to do this, there are 3, “itunes_artist_lyrics.sh” will get you both artist name/title and lyrics, and “itunes_artist.sh” will get you only the artist name/title, and itunes_lyrics.sh will get you the lyrics (if you want to run it on different output windows). By the way, this script don’t open itunes if it’s not running .
You can download it here -> (or download the git repository)
http://github.com/warstories/Geektool-Scripts
If you don’t want to clone the git repository, I added you a zip on github:
Download release 1.0 from git
This is a screenshot on how I show the lyrics, may be simple, but It works :
(you can se the lyrics on the left, some process information on the center, and the day on the right just above the watermark)
Next time I will try to load the artist cover and get it on the desktop with geektool, but for now, lets just listen to Arctic Monkeys, 505 (I can’t stop listening this song).
02.19.10iPhone USB tethering, error 0xE800006B, OSX 64Bit Kernel
Yeah thats right!, It took me too long to realize that, but its true.
You CAN NOT do usb tethering with a 64Bit Snow Leopard Kernel, I guess the drivers are still 32Bits.
You will not find this info on apple because, first tethering is not available on many countries (yes I have a jailbroken iPhone I’m not ashamed of that), and second the 64bit kernel is still targeted to servers, not users.
But I guess you are a power user 
, so don’t waste more time trying via usb, and do the tether stuff with bluetooth, it works great
.
Update Aug 2 / 2010, Today I updated to itunes 9.2.1 the usb tethering is now working on 64 bit kernel
.
02.18.10Flex: Dynamic Background Image on Canvas (redraw version)
Today I tried to load an image form an url and apply it to a background, well appears like setStyle don’t have the ability to load an image from URL.
So I had to look another alternative, I load the image using an Loader, but I couldn’t found a way to apply it to the background style, I did a workaround, I draw it on the graphics object, I guess it is helpful because the image is titled, but I will try more options I didn’t quite like 100% this solution.
IMPORTANT : dont’ forget the security restrictions of doing this, remember that flash can’t load images from another domain, and www.zerokernel.com is different to zerokenel.com, see Adobe for more information ( Player 9 restrictions from Adobe – PDF )
Anyway, here is the demo:

And the code:

12.4.09Teztoc updated
A good friend of mie has released a library to test individual flex components, its very useful when you build large apps with smaller components because it allows to check exactly how it behaves but without loading the whole app.
You can check the project here:
http://code.google.com/p/teztoc/
I will be posting an example soon
8080 Emulator on AS3
Yey, a good friend of mine worked on a 8080 emulator, to play space invaders…
Please go to see it, I bet it will be a cool code xD
Psychedelic process
I really like this process, To bad is not 64 bit xD
lsd process in snow leopard
Flex 3 / SVN plugin (subclipse) / change credentials / OS X
For a complex reason I couldn’t understand the SVN plugin of eclipse don’t have an interface for delete/update users for repositories, so if you want to change you current user you actually have to delete the “keyring”, that is a special file where eclipse saves all the login information of your repositories… yes… all the passwords.
So after a search in google with no luck, I found that the location of the configuration files:
@user.home/Documents/Flex Builder 3/configuration
BUT BEWARE READER….
All the configuration files are stored in hidden files, and I mean the filename starts with a “.” dot, if you go to the finder you will find nothing… apparently… you actually had to dig in your terminal skills (or configure the finder to show hidden files), and delete the damn file:
.keyring
And eclipse will ask for passwords again…
The worst thing… you had to enter ALL your passwords again.
09.14.09CDU-680 + Snow Leopard
Well the short answer, it works, but in the 32 bit kernel, it only gets the red led on 64 bit kernel.
I have searched around google and the Franklin Wireless page and found nothing, so I decided to install, ( I had a clean snow leopard), and it works.
I searched here:
http://www.fklt.com/support.php
There’s nothing in the forums or in the page about snow leopard support, so I think the 64 future is uncertain, only time can tell.
So if you are willing to sacrifice the great 64 bit performance for 3G connectionm go ahead, it will work
09.9.09Mysql 5.1.38 No mountable file systems / Snow Leopard 64bit Kernel
So… you finally decide to search in google about this problem, it took me 5 tries, before doing it.
So the short answer… the image for mysql is UDF, and appears like the UDF driver is still 32 bits, and I guess if you are here, is because you are running on the 64bit kernel…
Well this is the price for early adopters, you have to boot in 32 bits kernel to be able to mount it on snow leopard
Long history, and a linux workaround (?):
