Squeezebox2 : It is a networked player. The media server is written in Perl and released as a open source software. It seem that the media server doesn't support UPnP but it can import iTunes library easily.

Twonkeyvision : It is a implementation for UPnP Media server. It can scan the installed hard disk for music content in MP3, WMA or WAV format and build the logical tree automatically.

AKI-PIC Programmer v3.5 : I bought the PIC writer with the upgrade kit to start the programming, and assembled the writer. I bought some parts such as XPort, LCD display module, SC1602BSLB, and MP3 decorder chip, VS1001 too. Using the parts, I will create the networked speaker and the remote control such as AirPort Express or MusicCAST.

CppUnit : I found some tiny test unit libraries such as CppUnit-x and CUnit, but I tried and ported the standard test unit library to for T-Engine platform as following.

Using the library, I could run the sample test cast on the platform, T-Engine SH7727, as following. The standard console is outed to the terminal console :-)

HEW : I will use the C/C++ compiler for porting CyberLink C/C++ of ITRON, and I installed the compiler on my development PC. The look and feel is very similar to Microsoft's IDE such as the Visual Studio, and I could create the project easily. I tested to compile some sample codes, and I noticed the compiler doesn't support STL as default. To port some codes using STL, I will try and use SGI's STL with the compiler or rewrite the codes without STL like the Vector class of CyberX3D.

VAIO typeF : I installed Fedora Core3 to the note PC at home, but the installer is aborted with the following messages.

Assertion (heads < 256) at disk_dos.c:486 in function
probe_partition_for_geom() failed.

I knew that many users had same problem at the Bugzilla of Redhat, and I decided to delete the recovery partition for the WindowsXP. I could run Fedora Core1 on the same PC, so I deleted the all partition. Then I started the installer of Fedora Core3, and I installed it with no problem :-)

First, I installed the latest NVIDIA driver for the GeForce 6200 because the Fedora didn't recognize the new graphic chipset. According to the readme and the mailing list, I changed the Xorg configuration as the following.

Next, the wireless network card, Intel 2915ABG, wasn't recognized too. Then, I installed the wireless driver as the following steps.

PLC : In Japan, the power line communication haven't permitted yet for home network, but the government of Japan might permit by the end of this year. Then, Sumitomo Electric announced the 200Mbps modem as the development version.

In my home, I usually use the wireless network and the all rooms has a Ethernet connector at least using the combined power panel. However I am looking forward to be permitted the new network communication to connect classic home devices such as refrigerator and washer to home network easily :-)

WRITING SOLID CODE : I read the Japanese translated book again to write more solid codes. I read the book after an interval of ten years. I used to write source codes using assertion function only using C or C++, but I realized that I don't write using it recently. I implements my assertion function for Java because it doesn't support the function until J2SE 1.5, but I don't use the function enough. I can notice the critical error easily using the debugger and the test cases, so I may not use the assertion function recently. I checked my next target platform about the function. I knew that .NET Framework supports the function for all languages such as C#, but most of embedded platform such as ITRON might not support it because the platform has no the standard output by default.

iP4100R : I bought the new printer in my home. It is convenience for us not to connect my home note PCs and my old printer with a USB cable because it supports IEEE802.11b/g network :-)

JUMP to .NET : I knew a user of CyberLink for Java, Juan Pablo, converted the source codes to C# as the following.

From: TI6 Juan Pablo Cienfuegos Fernandez

Hello Satoshi!!

First of all, thanks for your great workt with Cyberlink. I�m doing my
Final Project in Germany (Fachohschule Ulm), and I have to develope an
application to synchronize the contents of two UPnP Media Servers.

I have used the Java Implementation of CyberLink and I have converted this
source to C# (with an automathic tool of .net)and now it is working nice.

............................

Microsoft Java Language Conversion Assistant : Then, I checked the conversion tool from Java to C#. I haven't checked the tool yet in more detail, but I would like to use it after I will do refactoring the Java source code more.
