  • 上一篇文章说过,我前一段事件买个$15/year的YardVPS,这个VPS内存只有128M,加上虚拟内存才256M。也干不了什么,所以拿它做一个个人的blog和wiki服务正好。blog的话,我们选择LNMP组合,即Linux+nginx+mysql+php-fpm,以节省内存、提高性能为目的。
  • 前文有做过OpenVZ和Xen主机的性能比较,个人因为OpenVZ的性能较好而更中意OpenVZ主机。
    `
    OpenVZ的最大问题在于内存,它把虚拟内存也计入你消耗的内存,无形中吃掉了大量的内存,OpenVZ有大量的公共开销免去了内存消耗,但两相比较下来很可能会比Xen占用更多内存。
    `
    这种多占内存的现象在多线程应用时尤为明显,这是因为一个线程默认就要占用8M的Stack,比如php-cgi5开5个线程的话,啥都没干就要吃掉40M内存。
    `
    这个省内存绝招就是修改Stack大小:

  • Godaddy最近变小气了很多,除了每月必见的1刀超级优惠码来得特别晚外,连一些域名续费的优惠码也都维持在30%这个幅度,大约要799刀,加上018的小费,要53rmb多.对于我们习惯50以内续费的来说,这个价格也算高了.

  • 've written this guide to present some basic information about Grub 2. It is meant for users who may be familiar with basic editing of the original Grub (Grub Legacy) menu.lst and wonder how it carries over to Grub 2. The current version of Grub 2 is 1.98; Ubuntu 9.10, Karmic Koala was the first Ubuntu release to use Grub 2 on new installations by default (1.97~beta4). In keeping with Ubuntu's "stable release" philosophy, 1.97~beta4 will probably remain the official version in 9.10/Karmic and will not be updated to 1.98. In this guide, any reference to Grub 2 will refer to 1.98 unless otherwise noted. The user can check their current version with the "grub-install -v" command.
  • GRUB 2 is the default boot loader and manager for Ubuntu since version 9.10 (Karmic Koala). As the computer starts, GRUB 2 either presents a menu and awaits user input or automatically transfers control to an operating system kernel. GRUB 2 is a descendant of GRUB (GRand Unified Bootloader). It has been completely rewritten to provide the user significantly increased flexibility and performance. GRUB 2 is Free Software.

  • Today the new iteration of Firefox will come out and I want to share a tip with you, how to speed up your Firefox 3.

    I was using nightly builds of Firefox 3 for about half a year and it was quite fun to observe the development – especially the different design decisions in the look and functionality of the Awesomebar, but in such a long time you visit a lot of sites and collect a lot of cookies. Since this information has to be in memory all the time for places to be fast and responsive, I will show you, how to optimize your Firefox database.

  • 总所周知,IPv6是目前比较好的翻墙方法之一,那么如何让自己的VPS支持IPv6接入呢?
    虽然你的VPS不支持IPv6,但是我们可以通过IPv6 Tunnel来解决,也就是平时说的IPv6 Over IPv4,可以理解成在IPv4上建立的IPv6的小管道。我们使用的是HE(Hurricane Electronics)提供的免费的IPv6 Tunnel Broker,HE拥有世界是最大的IPv6骨干网,在世界各地都有提供IPv6 Tunnel Broker的服务。
    下面的教程中,我将使用CentOS系统。

  • 2011年你在网上混,神马都是浮云,翻墙才是硬道理!
    网上免费的VPN一大堆,但是大多限制很多,限制不多的一定很垃圾,很慢,总之免费的东西只能让你偿个鲜,应个急,不能从根本上解决问题。
    幸好有VPS这个神奇的东西!
    下订单+交钱+等待开通,就这样一个属于自已的VPS到手了!
    于是激动人心一刻也就开始了。。。。。。。。。
    对于Linux VPS 我真的是一窍不通啊,更别说安装OpenVPN!于是找Baidu、找教程。。。。。。。。。。
