A Java Green Moment : Consolidation, CoolThreads Servers and Energy
Fri, 16 May 2008 19:23:00 -0700
Java apps running on a server take energy. My favorite servers are not quad-core procs - they are 8 core procs (with 64 hardware threads) and they are built to save energy. Bingo. The push to virtualization is about saving energy and money. More...

Setting up Static IP and NIS for OpenSolaris 2008.05
Fri, 16 May 2008 18:16:35 -0700
As part of OpenSolaris 2008.05 installation, Caiman installer automatically configures your ethernet card to provide a dynamic IP address. This is perfectly fine if you are working from your laptop. However, if you, like me installed it on your workstation like Sun Ultra 40 then you might want to do necessary things like assigning a static IP address with NIS authentication enabled etc to transition the system as a developer workstation. Now that I have tried out OpenSolaris 2008.05 LiveCD for more than 2
weeks now, I guess I am now ready to make OpenSolaris 2008.05 as my default OS. If you haven't yet, you might wanna download a copy from hereSo, here is how I went ahead with this transition - Disable Network AutoMagic(NWAM) service and enable traditional networking servicesvcadm enable physical:default svcadm disable physical:nwam- Now, you need to configure the static IP address for your ethernet interface. You could do this by using the network configuration GUI - 'System->Administration->Network GUI window to configure this as shown here Note: I am assuming that you know the IP address and the default gateway that you need to provide here. If not, you might want to talk to your Network administrator before you attempt this. - Now, I will restart all network services by doing some thing like svcadm restart milestone/network Now, I will move ahead and configure NIS for my system. Here is how itworked for me- Setup your domain name of your current network. NIS server need to reside within this domain as well. domainname <name here> - Copy /etc/nsswitch.nis to /etc/nsswitch.conf pfexec cp /etc/nsswitch.nis /etc/nsswitch.conf- Configure NIS Services pfexec ypinit -cThis above command will walk you through and ask you to provide NIS server IP addresses etc. and then bind the configured NIS server. pfexec /usr/lib/netsvc/yp/ypbind -broadcast - Finally, enable NIS service and restart all network services.. svcadm enable nis/client svcadm restart milestone/network- Now, you should be able to verify if NIS is working on your system by doing something like ypcat -k passwd -> should return a whole bunch of NIS user names within your domain. That is all there to do to translate a OpenSolaris system running in DHCP to a static IP address with NIS enabled

为地震死伤者祈祷
Fri, 16 May 2008 18:07:01 -0700
昨天我们公司的现场救助志愿者发回邮件的时候,公司里许多人哭了。不过令人欣慰的是,这次天灾以后我们看到了一个团结的民族,一个理性的民族,一个充满希望的国家和民族。我们看到了台湾同胞血浓于水的兄弟感情,得到了国际上的朋友的支持。我们甚至感染了那些以往对我们并不那么友好的一部分人。死者已逝 - 为他们点一只蜡烛。天堂的路上,不再孤独。(转一篇俄罗斯国家新闻网报道) 中国不需要同情,中国需要理解;中国不需要安慰,中国需要支持。我们愿以杯水之力,尽寸尺之能,和中国人民站在一起。我们知道,一个总理能在两小时就飞赴
灾区的国家,一个能够出动十万救援人员的国家,一个企业和私人捐款达到数百亿的国家,一个因争相献血、自愿抢救伤员而造成交通堵塞的国家,永远不会被打
垮。
希望必将与中国同在。
让我们为生者祝福,为死者祈祷。中国,走好。

Scala's Lift on GlassFish v3
Fri, 16 May 2008 17:53:46 -0700
I'm beginning to think we "undersold"
GFv3 TP2 when we called it a
Technology Preview as pretty much anything we are throwing at it works!
Check out Vivek's latest note on
Scala Lift Framework.
Starting with a Maven Archetype, it creates a Scala Lift project using a Derby database that can
deploy on GFv3 and, with a small change it can use v3 tp2 embedded for ease of development
through mvn glassfish:run. Neat!

「ファイル」を「ファイルセット」にマージ
Fri, 16 May 2008 17:53:22 -0700
6601818 Turn FileBench "files" into filesets with 1 entry のバグについて Drew が、ファイルに関する実装をファイルセットの実装にマージするという、すばらしい対応を行いました。FileBench News (2 ~ 3 か月に 1 回程度更新) に、変更点に関する Drew の言及があります。
これにより、2 年以上「ToDo」リストに載ったままだった問題が解決に向かい、ソースコードが大幅に簡潔化されました。この変更は大きなものなので、FileBench のバージョンは 1.1.0 に上がりました (直前のバージョンは 1.0.1)。この変更は OpenSolaris の build snv_81 に反映されており、Sourceforge でもすぐに確認できます。
改良に向けて、ほかにも作業を行っています。

FileBench 源代码和 Bug/RFE 信息
Fri, 16 May 2008 17:22:25 -0700
现在您可以在 OpenSolaris 中使用 OpenGrok 轻松浏览 FileBench 的源代码。我发现 OpenGrok 比 sourceforge 提供的工具更加友好。
对于源代码的基本细分条目,构成 C 二进制 "go_filebench" 的 *.c's、*.h's、*.l 和 *.y 文件可以在这里查看。同时,您还可以浏览工作负荷、主要的 perl 脚本 filebench(1)、.prof files 和 scripts 来比较结果并刷新文件系统缓存。
现在您还可以在我们的 bug 数据库中查询在 FileBench 中发现的 bug,以及在 OpenSolaris 上请求的 RFE。
