_1 切手サイズで1GBのプラスチック媒体「Info-MICA」 (AVWatch)

CDやDVDドライブのような回転機構が不要

CCDの映像素子で撮像し二次元複合、元のデジタル情報を復元する

かなり魅力的．ひさしぶりに来そうだ．今後要チェックだな．NTTによる公式サイト．

使い捨て可能なメディアっていうてるけど，使い捨てってどういう意味？それって環境にも優しくないし表現的にも良くないだろ．

まさにSTのアイソリニア・チップ(1,2)ですな．

_2 iPodバッテリ訴訟 (ITmedia)

忘れてた．iPodにはこんな大きな問題が残されているんだった．バッテリが交換可能になればもういうことなしなんやけどな．Appleの今後の対応に注目．

_3 MPIO Project

彼女さんが持っているmp3プレイヤをLinuxから利用するためのツール．これでまた一歩新生活でのマシン環境への障害が取り除かれそうだ．

_4 Re: gentoo-sources vs gs-sources

While I was executed emerge-webrsync on gentoo-sources kernel, my linux box rebooted suddenly. I don't know why the system reboot. After booted, I continued to execute emerge-webrcync and the error message "aux_get():" was displayed. I show error log bellow.

processing app-admin/fam
Generating cache entry(0) for: /usr/portage/app-admin/fam/fam-2.6.10-r1.ebuild

aux_get(): (0) Error in app-admin/fam-2.6.10-r1 ebuild. (256)
               Check for syntax error or corruption in the ebuild. (--debug)


error processing app-admin/fam-2.6.10-r1, continuing...
Generating cache entry(0) for: /usr/portage/app-admin/fam/fam-2.7.0.ebuild

aux_get(): (0) Error in app-admin/fam-2.7.0 ebuild. (256)
               Check for syntax error or corruption in the ebuild. (--debug)

I understood this error messege is that I use ebuild with --debug option. So I execute below command.

# etcat -v portage --debug

The result of this is below.

Traceback (most recent call last):
  File "/usr/bin/etcat", line 1105, in ?
    main()
  File "/usr/bin/etcat", line 1101, in main
    function(query)
  File "/usr/bin/etcat", line 496, in versions
    tup = smart_pkgsplit(query)
  File "/usr/bin/etcat", line 332, in smart_pkgsplit
    elif ord(c[0]) > 47 and ord(c[0]) < 58:
IndexError: string index out of range

I guessed that the .build files were not download completely or the portage database might be broken. So, I moved /usr/portage directory temporary and made new /usr/portage directory. After that I re-execute emerge-webrsync. As a result that, the "aux_get():" error message was not shown again. Of course, some files might be broken.

I don't know why this error occured. While I used gs-sources kernel, I have not encountered such this accident. I decided to go back my kernel from gentoo-sources to gs-sources. In fact, I felt the bad response of completion of zsh or so. I installed gs-sources-2.4.23-pre8-gss-r2. This new kernel improve the performance. It may be that I can't used to gentoo-sources. Some strange optimization option might be set. I decided to go using gs-sources from then on.

If you cannot understand this explanation, please send mail to me (mux03 at iijmio-mail.jp). I would answer as much as possible.
