Nokia on Wednesday announced a trio of new phones, including one that can store up to 3,000 songs.

The N91 has an integrated 4GB hard disk and supports digital music formats including MP3, M4A, AAC and WMA, Nokia said.

Additionally, the handset comes with a stereo headset with remote control. The N91, expected to ship by the end of the year, will also feature a 2-megapixel camera, e-mail support, a Web-browser and video-sharing capabilities, the device maker said.

The phone supports WCDMA, wireless local area networking and Bluetooth, and subscribers can shop at online music stores directly from the device, the company said. Users can synchronize the device with their computers via USB 2.0 and create and manage playlists that, in turn, can be shared with others via Bluetooth, e-mail or multimedia messaging.

Another new WCDMA handset from Nokia is the N70, a smart phone featuring a 2-megapixel camera, a flash and "front camera" for video calling, stereo FM radio, a digital music player, visual radio and 3D games. The camera has a "slide and shoot" design, in which the slide automatically activates the camera.

The handset's camera has an integrated flash, 20x zoom capability and other options. Video and photo from the camera can be transferred on to a PC; organized in a slideshow or album on the camera; or printed using a USB cable, Bluetooth or reduced-size dual voltage multimedia card. The device is expected to be available in the third quarter.

Lastly, the Finnish phone maker announced the N90, which features a 2-megapixel camera with autofocus and 20x digital zoom, an integrated flash, video capture with editing functions and Carl Zeiss optics, Nokia said. Carl Zeiss optics, named for the pioneering German optician, are used for projection and illumination.

The handset's rotating camera barrel is designed to let users shoot video, as well as pictures. When the main display is unfolded and twisted, the N90 can be used to shoot video in MP4 format.

The N90 also features different options for storing, sharing and printing photos and video clips, and it supports 3G functions such as two-way video calling, video streaming and Net surfing. It is a triband phone for GSM 900/1800/1900, EDGE and WCDMA networks.

终于解决pcmcia 网卡在2.6kernel的问题

原因是ISA没有编译内核
原来老的pcmcia卡还是被模拟成isa设备的
:(

对了，还要在/etc/modules.autoload.d/kernel-2.6中加入

终于搞出了我古董笔记本的800x600分辨率

以前明明在rh9时可以用800x600，装了gentoo之后xorg 6.8.2居然
只能上640x480
google了一整天

最后观察/var/log/Xorg.0.log发现
原来是Xorg -configure测出来的hsync out of range了
而xorgconfig又不能测出来显卡类型

解决办法：
先用xorgconfig配置，在刷新频率处故意往大了设
反正LCD也无所谓
然后手工改/etc/X11/xorg.conf里的vga driver为siliconmotion
即可

第一次hack gentoo ebuild

也许算第二次了，不过上一次是因为参照bugs.gentoo.org上针对d4x-2.5.0不能在
gnome 2.6的编译照着葫芦画了个瓢
这次是因为发现gcov在ppc的结果不正常想要看gcov的中间过程
而gcov是gcc的一部分，如果自己编译gcc那可就太麻烦了
幸好有gentoo，gentoo有ebuild

hack步骤如下：
emerge --fetchonly gcc-3.3.5-20050130
然后tar xvjf gcc-xxx.tar.bz2
然后分别创建目录
mkdir gcc-3.3.5-orig/gcc
mkdir gcc-3.3.5-dbg/gcc
cp gcc-3.3.5/gcc/gcov.c gcc-3.3.5-orig/gcc
cp gcc-3.3.5/gcc/gcov.c gcc-3.3.5-dbg/gcc
只复制一个文件是为了patch小一点
然后修改gcov
然后diff -Nur gcc-3.3.5-orig gcc-3.3.5-dbg > gcov-cbd.patch
然后把patch放到/usr/portage/sys-devel/gcc/files
然后改ebuild文件
加一条epatch ${FILESDIR}/gcov-cbd.patch
然后emerge gcc-xxx.ebuild就可以了

initrd-version.img从哪里来？

今天和同事争论make kernel之后/boot里的initrd-$(version).img从哪里来的问题
虽然我知道肯定是make kernel的时候搞出来的，但是具体怎么做的还真没仔细研究过
正好2.4.30出来了，按惯例也要装上去一用，就顺便把这个未知的东西搞搞清楚。
结论如下：

make install ->
./Makefile (ln261) include arch/$(ARCH)/Makefile ->
./arch/$(ARCH)/Makefile (ln119) $(MAKEBOOT) = Make -C arch/$(ARCH)/boot ->
./arch/$(ARCH)/boot/Makefile (ln40) sh -x ./install.sh ... ... ->
./arch/$(ARCH)/boot/install.sh (ln25) /sbin/installkernel ->
/sbin/installkernel (ln65) new-kernel-pkg ...
