新搜索引擎 Quintura

平时比较习惯用 Google,今天听人介绍看了一眼 Quintura,感觉很不一样,特别是它对内容的组织方式。

不过它是否会改变我的使用习惯呢?我觉得很可能不会,但是对于喜欢浏览的搜索用户来说,也许这种形式会更好地呈现更多的信息。

With several production environment installations, I am now very confident with RELENG_7's stability and performance. After some discussion with alu@ we have reached the consensus that we should upgrade the system to RELENG_7.

Previously, www.FreeBSDChina.org runs a version used to call as "delphijfork", which adds several stability improvements, performance enhancements from newer FreeBSD development branches. With RELENG_7, we are able to get rid of almost all these local hacks.

关于工作与生活zz

我有个有趣的观察,外企公司多的是25-35岁的白领,40岁以上的员工很少,二三十岁的外企员工是意气风发的,但外企公司40岁附近的经理人是很尴尬的。我见过的40岁附近的外企经理人大多在一直跳槽,最后大多跳到民企,比方说,唐骏。外企员工的成功很大程度上是公司的成功,并非个人的成功,西门子的确比国美大,但并不代表西门子中国经理比国美的老板强,甚至可以说差得很远。而进外企的人往往并不能很早理解这一点,把自己的成功90%归功于自己的能力,实际上,外企公司随便换个中国区总经理并不会给业绩带来什么了不起的影响。好了问题来了,当这些经理人40多岁了,他们的薪资要求变得很高,而他们的才能其实又不是那么出众,作为外企公司的老板,你会怎么选择?有的是只要不高薪水的,要出位的精明强干精力冲沛的年轻人,有的是,为什么还要用你?

Gea-Suan Lin发的,怀念一下吧。想想看,除了Vista之外的版本和一些史前版本(为了凑数当年还专门搞过Windows 1.0 -_-#)之外基本上都用过了。。。

如题,在此表示衷心感谢。这个delphji帐号长期发表误导性的和不文明的言论,终于被砍了。

另,我个人强烈怀疑这是某个“自主知识产权”操作系统的开发组雇佣的枪手,目的是炒起话题。

FreeBSD ZFS from scratch

| 1 Comment | No TrackBacks

This article describes how to install FreeBSD on ZFS from installation CD-ROM, with ZFS as root partition.

PREPARATION

You need to prepare a 'disc1' of FreeBSD, as well as a 'LiveFS' disc. Also, you should be familiar with daily operation of FreeBSD system administration.

In order to use ZFS on FreeBSD, one has to use FreeBSD 7.0 or better. For better stability and performance, you should have at least 1GB of RAM, and preferably running on a CPU which is capable to run FreeBSD/amd64, fortunately, most modern CPUs does support this.

FreeBSD 7的TSO特性

因为我用的网卡多数都是em(4),所以在最近的升级中也就利用了它提供的TSO功能。TSO是一项减少服务器负载的技术,其原理是将TCP相关的一部分计算交给网卡去做。

Bill Fenner辞去src/ committer

被Grim Reaper嚷了40多次,其实有时候觉得这个机制也有它的一些不足。

OpenBSD发布了4.2的主题曲100001 1010101。FSF雇佣的法律打手SFLC最终不得不承认了自己的失败。

The starting line is nervous
we burst upon the course
Electric is our passion
An open hearted force

The water's full of dangers
That interrupt the flow
And soon the spirit splinters
as temptation takes its toll

*Give and get back some
Sharing it all
Path we know best
we're having a ball
Opulent mission
Lost in our passion
You can still choose
If you don't swim to win
you'll never lose*

One Zero Zero Zero Zero One

The window is a wall by now
A sieve of sickened holes
The water chicken stealing maps
Mistaking us for foes

The sun a son of Icarus
Flies too close to itself
Forbidden fruit is blinded
by the toys upon the shelf

*CHORUS*

One Zero One Zero One Zero One

Slow and steady wins they say
but this is not a race
It's not about who takes a prize
for first or second place

Imaginary rings of brass
Were traded for real goals
The vision and the mission lost
For those with corporate souls

*Give and get back some
Sharing it all
Path we know best
we're having a ball
Give and get zeros
Give and get ones
Given to you but
Not you to us
Opulent mission
Lost in our passion
You can still choose
If you don't swim to win
you'll never lose
You'll never lose*

看到了一群神仙

| No Comments | No TrackBacks

今天看到了 Murray 和 Nik 两位老大。Paul Saab有一些私人的事情没来,所以没有看到。在 Sunnyvale 举办了这次 GSoC mentor 的 party(游泳池不错!),来了很多以前听说过的神仙(有个老印还给大家吹一种类似萨克斯的乐器,据说他去年就这么做过一次,不知道是哪个项目的神仙),比如 moinmoin 和 pidgin 的作者等等,与此相比,FreeBSD的人反而显得单薄了一些(算上我3个),看来明年我们还是有很多需要改进的地方的。

吃完晚饭和 NetBSD 的两位聊了聊 SCM,他们对 subversion 之类的新工具提出了很多质疑,我觉得说的问题确实很在理,另一方面,我认为gcc转svn做得也比较失败。

全都是神仙啊。。。

Complains about can not reach www.freebsd.org was popped up on FreeBSD mailing list. This is believed to be caused by hardware issue, as reported by Simon Nielson recently.

mailman vs postfix

| No Comments | No TrackBacks

以前一直觉得mailman与postfix的VERP支持配合的很不好,今天把它patch掉了。需要注意一点即 postfix 的smtpd_authorized_verp_clients默认设置为$authorized_verp_clients,这个值没有意义,需要自己改成合适的值。

patch过之后,mailman就可以直接利用postfix的VERP能力了。这样,同一个域名下的用户便可以反复重用同一个SMTP session,从而大大提高deliver的效率。

搬家

| No Comments | No TrackBacks

在几位同事的帮助下,今天总算是从 Budget Motel 搬到新租的房子里面去了。Mountain View的地价很高,房租基本上是全美平均水平的2倍多(前天给在芝加哥附近的老V打电话让他往高猜,果然咬了牙猜的数字是这边的一半),初来乍到,决定找个apartment先和人share一下。

和我share apartment的是一个老美,白人,在一家做卫星的公司工作 -_-# 敬仰之情犹如滔滔江水……
