Chys's random notes. Study more problems; Talk less of isms. Trying out X32 ABI. By chys on September 6th, 2012. Is a variant of x86-64 ABI which uses 32-bit pointers (thus limiting the address space of a process to 4 GiB). Today I found I had the mood to try it out, but soon discovered it was so challenging…. Recalling Gentoo released a x32 Relese Candidate. I guessed it might be a good idea to install it in VirtualBox. But soon, I found I was unable to chroot. Then I tried the Ubuntu. Also known as x86...

Nothing to do with math. 据说使用 info 域名的黄色网站很多,但是它最便宜,所以顾不得这么多了。再说 .net、.com 下面已经难得找到这么短的。 65292;总算把网站的雏形搭起来了,也会用 PHP 写一点东西了,不过 MySQL 还是不会。 WordPress. 也装好了,并且把另一个 blog 上的文件转移了过去。这里的东西就算了:一来 WordPress 导入 Blogger 时把 label 全部变成了 category,而我希望的是它们变成 tags,这里这么多贴子一篇一篇地改也累;二来这里有一些东西我不愿意让搜索引擎索引。 因为虚拟主机在 GoDaddy,所以嘛,(1) 从 CERNET 不能免费访问; (2) 由于众所周知的原因,不保证国内总能正常访问。 Saturday, January 31, 2009.
