Freebsd

在 FreeBSD 下配置 HP LaserJet 4000 和 HP LaserJet 2100 打印机

以前一直以为配置起来很麻烦，现在看来并不是这样。

我现在的办公室里面使用的是 Windows 打印服务器，而 Windows 打印服务器和 HP 打印机之间是通过 TCP/IP 连接的（不过为什么还需要这个打印服务器？先不管它）。最近因为工作原因需要相当多的打印任务，但是我自己没有合法的 Microsoft Office 授权，因此，寻找合法的、开源解决方案便势在必行了。

我平时使用的桌面系统是 FreeBSD，采用 GNOME 作为窗口管理器，平时主要是用它来进行开发，因此也没研究过打印的事情。说了很多废话，现在我们来看在 FreeBSD 上面需要先做些什么？

1GB page on AMD processor

So now AMD 0x10 processors can handle 1GB pages, according to Alan Cox’s commit today! It would be exciting to see it on FreeBSD 8.0 (already in -HEAD).

(I’m still looking for a development desktop PC donation, see the FreeBSD wantlist)

FreeBSDChina Wiki正式开通

昨天我们终于将 FreeBSDChina Wiki 正式对公众开放了，希望能够有更多的人加入。

见了一群湾区的committer

今天M. Warner Losh (imp@,core)路过湾区，于是Cisco的Randall Stewart(rrs@)就发信说要来个湾区committer小聚，地点离我住的地方不远，于是就去了。

迟到了3年的wiki

3年前 FreeBSDChina.org 在上海的年会上，我们讨论了使用 wiki 来进行翻译组织的可能性，不过一直都没有实现。前天终于架了一个实验性的系统，无论如何，better late than never。

Migrating www.FreeBSDChina.org to RELENG_7

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.

FreeBSD ZFS from scratch

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。
