no ski, no life

I upgraded my vaio-p from fedora 14 to 16 a while back as X finally became working w/o any closed blobs, only w/ kernel built-in psb_gfx (thanks a lot alan cox for creating this!) + X fbdev.

In Fedora 16, gnome-shell is the default desktop. Unfortunately, 3D acceleration required for gnome-shell is not available in vaio-p: fbdev + psb_gfx do not support 3D acceleration yet and gnome-shell does not work in native mode (run in fallback mode) until Features/Gnome shell software rendering is implemented in Fedora 17.

Gnome-shell fallback mode works fine but it has some features I don't like, so I finally decided to switched to xmonad w/o gnome env. from gnome + xmonad. To accompllish this, I made ~/.Xmodmap, ~/.Xresources for urxvt (rxvt-unicode), ~/.xmonad/session to start {gnome-keyring-daemon, tayer, nm-applet, ibus-daemon}, ~xmobarrc and rpm specs for tayer and yeganesh (tayer.spec, yeganesh.spec and yeganesh-2.4-build-wo-xdg.patch to build yeganesh w/o ghc-xdg-basedir-devel). And I also updated ~/.xmonad/xmonad.hs works w/o gnome:

Now almost all work fine and I quite pleased with this my new lightweight and very efficient desktop env.

Here is a screenshot:

from all_eq and longest_common_prefix in rpmkit/swapi.py:

# import itertools

def all_eq(xs):
    """Whether all items in xs (list or generator) equals each other.

    >>> all_eq(c for c in "")
    False
    >>> all_eq(c for c in "aaba")
    False
    >>> all_eq(c for c in "aaaa")
    True
    >>> all_eq([c for c in "aaaa"])
    True
    """
    if not isinstance(xs, list):
        xs = list(xs)  # xs may be a generator...

    return xs and all(x == xs[0] for x in xs[1:]) or False


def longest_common_prefix(*args):
    """Variant of LCS = Longest Common Sub-sequence.

    >>> longest_common_prefix("abc", "ab", "abcd")
    'ab'
    >>> longest_common_prefix("abc", "bc")
    ''
    """
    return "".join(x[0] for x in itertools.takewhile(all_eq, itertools.izip(*args)))

I've just released xpack-0.2. Now it looks working on debian system as far as tested in chroot-ed debian system built with debootstrap.

(xpack is an automatic package building tool just from file list, available from https://github.com/ssato/rpmkit )

東京電力の計画停電のリストが PDF (しかもテキストコピー禁止) しかなくていらいらするので全部まとめて、更新があるか手元になければダウンロードして csv 出力するという一連の Makefile とスクリプトを書いてみました: https://github.com/ssato/misc/tree/master/tepco. しかし今は xls 形式もあるようなのであまり意味がなくなってしまったかも。とりあえず意地で xls からの変換にも対応済み。

必ず make -n 等で事前確認を。python-xlrd が必要。やっつけで適当なので Makefile の内容を理解できる方だけ自己責任でどうぞ。なおかつ不正アクセスととられないように頻繁な実行は絶対に避けて下さい。

I continued working on xpack.py and added some features since its 0.1 release.

As still I don't have a chance to test .deb output and am not sure whether that function works or not in actual. If anyone tried and found any problems on it, please let me know.

I wrote a script to make "package" in tgz, rpm or deb (experimental) from given files list. Here is an example session how it works:

If you're interested in it and want to see how it works and what can be done with it, take a look at the output of `xpack.py --show-examples` also.

The idea behind this script is that the system should be consist of static data ('packages') and 'procedual' setup process (such as creating and editing /etc/httpd/conf.d/foo.conf, recovering dot files in users' dirs from backup data, etc.) be removed at a maximum.

What is more, I want to remove most manual and 'procedual' configuration steps need human interaction except for installation of some additional packages to setup our systems.

This script will help packaging configuration files modified by users manually and user data, so to install these packages finishes the system setup almost.

I don't have time to become a package maintainer of fedora project for a while but have some rpm specs for fedora in several git repositories: https://github.com/ssato/misc, https://github.com/ssato/misc/tree/master/trac-macros and https://github.com/ssato/misc/tree/master/trac-plugins for example. I think some of them are useful for others, e.g. the rpm spec for python-xlwt. Does anyone interested in taking over these?

A little bit late but ...

Our second daughter, Asuka, was born on 2010.11.29, 14:11. She was 3055g at birth and looks a lot like her elder sister, Karen. My wife and she are both OK and I can't wait that they leaves the hospital and come home.

At last: Using C++ in GCC is OK

The article about packaged vm is out: Software Design 2010年6月号 but miniascape is not in usable state yet and I keep hacking on it.
