I just updated my MBP to the latest Apple’s OS 10 ( leopard ) the system is good, few eye-candies updates, although was a bit disappointing don’t see java6 around ( they removed the early beta version from ADC as well, so, don’t waste your time looking for it).

Apple, I don’t care about java6 for now you can delay it until you make it good. BUT… man when you delivery something with your OperatingSystem make sure that this thing works, I got really angry with a BUGGED java5 version, the exactly version is

java version “1.5.0_13″
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)
Java HotSpot(TM) Client VM (build 1.5.0_13-119, mixed mode, sharing)

This bug looks like its deep inside Apple’s windowing toolkit implementation as you can see in the following stack trace

Exception in thread “AWT-EventQueue-0″ java.lang.NullPointerException

A guy from GWT dev list submitted a bug report to Apple: Problem ID 5563333 - “CGraphicsEnvironment NullPointerException breaks continually on OsX 10.5″, so engineers and QA move your asses and get this thing done, because you are affecting my work and some more guys around the world.

Today, after read something about the Kawa IDE, I tried to remember these I’ve used through the years.

• Turbo Pascal - late 1997
• Turbo C++ - 98/99
• DJGPP - late 99
• Emacs - 2000 - C++
• Kawa - 2001 - Java
• Netbeans- 2002/2003
• Eclipse - 2003/2006
• Visual Studio - 2006 - Yes I got a project in C#
• IDEA intellij + textmate - 2007

Maybe I missed something, but it’s just to get an overview.

Written by a leading developer and maintainer of the Linux kernel, Linux Kernel in a Nutshell is a comprehensive overview of kernel configuration and building, a critical task for Linux users and administrators.The book is available for download in either PDF or DocBook format for the entire book, or by the individual chapter.

To quote of the book’s author:

If you want to know how to build, configure, and install a custom Linux kernel on your machine, buy this book. It is written by someone who spends every day building, configuring, and installing custom kernels as part of the development process of this fun, collaborative project called Linux. I’m especially proud of the chapter on how to figure out how to configure a custom kernel based on the hardware running on your machine. This is an essential task for anyone wanting to wring out the best possible speed and control of your hardware.

Last April, UC Berkeley, one of the premiere schools in the United States, announced its plan to put complete academic courses on iTunes. Fast forward nine months, and you can already find 59 full courses ready for your iPod. Simply click here to access Berkeley’s iTunes site (or here for the Rss feed).

No matter where you live, you can access at no cost the very same courses attended by students paying full tuition. And, given the critical mass of courses being offered across a range of disciplines, you can put together your own personalized curriculum and expand your horizons on the fly.

That’s include interesting computer’s science coursers like, CS 162 - Operating systems and System programming and CS 61C - Machine Structures. You can listen this podcast and forget about these classes in university (but I think that your teacher will not appreciate)
