Project Nevada G11N and its live repositories are online now!
This project is to provide internationalization and localization of
OpenSolaris Nevada release software to enable input and output of
international characters, and also to allow access of cultural
convention data and appropriate display of cultural elements in
OpenSolaris software.
You can find more information about Nevada G11N from:
http://www.opensolaris.org/os/project/nv-g11n/
For the live repositories of project Nevada G11N:

As Mercurial is more and more in vogue inside Sun, many workspaces need to be converted from other Source Code Management (SCM) into Mercurial. hgsvn is a good tool to convert SVN based workspaces into Mercurial (HG) based.
- Download latest version of hgsvn (current version is 0.1.3):
http://cheeseshop.python.org/pypi/hgsvn
- Untar hgsvn, then install (setup.py will download setuptools during installation):
$ cd hgsvn-0.1.3
$ su -
{passwd}
# export http_proxy="http://webcache.japan.sun.com:8080/"
# python setup.py install
- Create and pull svn workspace:
$ mkdir g11n-ws
$ hgimportsvn http://agc163.prc.sun.com/svn/cws/g11n-ws/trunk g11n-ws
$ cd g11n-ws
$ hgpullsvn
- voila

Five years ago when I joined Sun China ERI, Li was the site lead. He set up the site, then left Sun to MSN China. He then left MSN after around a year. He's now head of Mozilla China:

Maybe it's true that some people like the adventure and excitement of the Startups. Or maybe there's really an un-visible ceiling over there.

There are a couple of killing features in the coming NetBeans IDE version 6.0 (will be released in this November according to roadmap).
I especially like the JRuby on Rails Support, and the Swing GUI Builder. You can find the Flash demos from netbeans.org for them.

I'm using Ubuntu 7.04 as the desktop. The version of Firefox on Ubuntu is 2.0.0.3 (just updated to 2.0.0.4 yesterday). There is a handy feature introduced in Firefox 2.0.x series: 'Undo Close Tab'. At the beginning, this menu appears when right clicking on the Tab. But it will disappear later.
I thought it was because I installed GreaseMonkey extension. Yup, Grease Monkey is too powerful, and will bring un-expected effects sometimes. I tried to uninstall GreaseMonkey extenion, but I still can't find the 'Undo Close Tab' in the menu. I also created a brand-new profile (mv .mozilla .mozilla.bak, then launch Firefox). I can see 'Undo Close Tab' at first, then I lost it after restart Firefox several times.
When I searching through the settings on Preferences, I found a 'Startup' setting on 'Main' tab. The 3rd option for 'When Firefox starts:' is 'Show my windows and tabs from last time'. I happened to choose it, then 'Undo Close Tab' is back again. And it works pretty well until now.

It's convenient if the email alias (mailing list) is archived and browse-able to new comers. To achieve this, simply add webarchives@Sun.COM into your email alias through http://netadmin . Then you should be able to browse the email archives through: https://onestop.sfbay.sun.com/mailfinder/aliases_archived.shtml.

I'm using both Subversion (SVN) and Mercurial (HG) for source codes management (SCM). There are some differences between them for daily using. I document them in this article and update it when I find new differences.
- commit : push
'svn ci' will commit the server directly
'hg ci' will commit to local history
'hg push' will push the changes to server
- locally : globally
all svn cmds will check current and subdirs only, eg commit, status
but hg cmds will check globally, including the whole workspace
if you want to check current and subdirs only, append '.' to hg cmds
eg, hg status .
- partially checkout : fully checkout
svn can checkout a portion of the workspace (a module or subdir)
hg can't, it will clone the whole workspace
- empty dir
mercurial will ignore empty dirs when invoking 'hg add', more details
if you want to add those dirs into mercurial, add a hidden file under it
$ touch subdir/.hidden
$ hg add subdir
- symbolic link
mercurial 0.9.3 doesn't support symbolic link file type:
[qd139970@agc141 rtc]$ hg --version
Mercurial Distributed SCM (version 0.9.3)
Copyright (C) 2005, 2006 Matt Mackall <mpm@selenic.com>
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
[qd139970@agc141 rtc]$ hg add RTC_Template_O5U1
RTC_Template_O5U1: unsupported file type (type is symbolic link)
[qd139970@agc141 rtc]$
PS: link1 and link2 mentioned that this feature is supported in trunk.
PS2: Mercurial 0.9.4 supports symbolic links now(Jun 25, 2007).
- account name
Mercurial will look at $HOME/.hgrc to get the account info when 'hg commit',
if there's not 'username' entry in $HOME/.hgrc, Mercurial will use
$USER@$HOSTNAME as the username in log message.
if this is not what you want, please specify your username in $HOME/.hgrc
[ui]
username = [your prefer username]
- multiple heads
it's quite easy to create multiple heads in Mercurial workspace.
you commit new changeset locally, and 'hg pull' from parent workspace
to get new changesets from team members, then two heads created.
'hg heads' will show the heads information.
if multiple heads exist, you need to 'hg up && hg merge && hg commit'
before you can 'hg push' your changeset to parent workspace.
one possible way to avoid the mess is running 'hg pull && hg up' before
you commit any modifications.
if you enable hgext.fetch extension, 'hg fetch' will do this for you:
'hg pull && hg up && hg merge && hg commit'
add following two lines in $HOME/.hgrc can enable hgext.fetch extension
[extensions]
hgext.fetch =

It's pretty easy to add clustrmaps and page-hits in the theme of Sun Blog.
- register your blog, say http://blogs.sun.com/simford, in ClustrMaps: http://clustrmaps.com/getone.php
- Copy HTML lines from your ClustrMaps login page
- In 'Preferences/Theme' setting page, click 'Custom' button
- In 'Preferences/Templates' setting page, click edit button of 'Weblog' entry
- Paste the HTML lines from ClustrMaps in proper place:
<div>
<a href="http://www2.clustrmaps.com/counter/maps.php?url=http://blogs.sun.com/simford" id="clustrMapsLink"><img src="http://www2.clustrmaps.com/counter/index2.php?url=http://blogs.sun.com/simford" style="border:0px;" alt="Locations of visitors to this page" title="Locations of visitors to this page" id="clustrMapsImg" onError="this.onError=null; this.src='http://clustrmaps.com/images/clustrmaps-back-soon.jpg'; document.getElementById('clustrMapsLink').href='http://clustrmaps.com'" />
</a>
</div> - Add page hits info in similar place
<div class="rFolderitem">
#set($refs = $model.weblog.getTodaysReferrers())
#showReferrersList($refs 30 20)
</div> - click 'Save' button

OS: Solaris Nevada (build 59, sparc)
Mercurial: 0.9.3
Due to the lack of 'diffstat' tool on Solaris, the notification extension (hgext.notify) doesn't work well on Solaris. After several trying, I finally made it work.
Here is the setup steps:

# set this to False when you're ready for mail to start sending
test = false
config =
# repos live in /workspace/scm/hg/hgroot on server, so strip 5 "/" chars
strip = 5
# you can override the changeset template here, if you want.
# If it doesn't start with \n it may confuse the email parser.
# here's an example that makes the changeset template look more like hg log:
template = \ndetails: {baseurl}{webroot}/rev/{node|short}\nchangeset: {rev}:{node|short}\nuser: {author}\ndate: {date|date}\ndescription:\n{desc}\n
[reposubs]
# key is glob pattern, value is comma-separated list of subscriber emails

Accessing Mercurial through http/apache is handy, but it requests the workspace is owned by the same user with httpd (webservd:webservd on solaris). So accessing Mercurial over ssh tunnel is a better choice (this is also the way http://www.opensolaris.org/ chose).
Client side:
- $
ssh-keygen -b 1024 -t dsa
[ create id_dsa.pub for server side ]
[ui]
username = User Name <user.name@example.com>
Server side:
- $ cat <<EOF > $HOME/.ssh/authorized_keys

It seems that this is bug that we need to reboot the OS to make cvs server work.
Believe me, I tried many ways to avoid this but failed

My v240 server has 4 disks: 73G x 2, 140G x2. So I decided to create RAID1 to keep my data safer.
I used following partition layout to install Solaris Nevada build 59:
- /c1t0d0s0 / 30G
- /c1t0d0s1 swap 2G
- /c1t0d0s6 100M
- /c1t0d0s7 /export 38G
- /c1t2d0s6 100M
- /c1t2d0s7 /workspace 140G
Steps to create RAID1 for all partitions (as root account):
- prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
- metadb -afc 2 c1t0d0s6 c1t1d0s6
- metainit -f d10 1 1 c1t0d0s0
- metainit -f d20 1 1 c1t1d0s0
- metainit d0 -m d10
- metaroot d0
- metainit -f d11 1 1 c1t0d0s1
- metainit -f d21 1 1 c1t1d0s1
- metainit d1 -m d11
- metainit -f d17 1 1 c1t0d0s7
- metainit -f d27 1 1 c1t1d0s7
- metainit d7 -m d17
- prtvtoc /dev/rdsk/c1t2d0s2 | fmthard -s - /dev/rdsk/c1t3d0s2
- metadb -afc 2 c1t2d0s6 c1t3d0s6
- metainit -f d18 1 1 c1t2d0s7
- metainit -f d28 1 1 c1t3d0s7
- metainit d8 -m d18
Change /etc/vsftab from:
/dev/dsk/c1t0d0s1 - - swap - no -
/dev/dsk/c1t0d0s0 /dev/rdsk/c1t0d0s0 / ufs 1 no -
/dev/dsk/c1t0d0s7 /dev/rdsk/c1t0d0s7 /export ufs 2 yes -
/dev/dsk/c1t2d0s7 /dev/rdsk/c1t2d0s7 /workspace ufs 2 yes -
to
/dev/md/dsk/d1 - - swap - no -
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no -
/dev/md/dsk/d7 /dev/md/rdsk/d7 /export ufs 2 yes -
/dev/md/dsk/d8 /dev/md/rdsk/d8 /workspace ufs 2 yes -
24. lockfs -fa
25. reboot
After reboot,
- metattach d0 d20
- metattach d1 d21
- metattach d7 d27
- metattach d8 d28
- metastat ## check the status of all mirrors
- installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t1d0s0 ## install bootblk to c1t1d0s0
- ls -l /dev/dsk/c1t0d0s0 ## get the symbol link
- lrwxrwxrwx 1 root root 43 Mar 29 21:32 /dev/dsk/c1t0d0s0 -> ../../devices/pci@1c,600000/scsi@2/sd@0,0:a
- init 0
- ok> devalias ## check device
rootmirror /pci@1c,600000/scsi@2/disk@1,0
rootdisk /pci@1c,600000/scsi@2/disk@0,0
16. ok> boot rootmirror ## test bootblk in mirror partition
If everything is okey, then that's it.
