百团大购来也

Jeffye — Fri, 23 Jul 2010 23:18:16 +0000

第一次参加团购是在学校的bbs上组织的。那时团购刚刚兴起，对这个新生代事物是既向往又害怕，向往是因为它的便利和优惠的价格，害怕是上当受骗。当学校bbs上发出团购信息时，踊跃的试了一次，也正是这一次团购的成功，打消了团购的顾虑。经过几年的发展，大家的消费观念、方式都在不断的发展，团购已成为大多数人的消费方式之一。目前的团购信息主要集中在大家熟悉的论坛，学校的bbs，各自小区的论坛等等，信息比较分散，而且很多时候难以找到志同道合的需求者，即是找到数量上也不够，团购的梦想破灭，不得不花高代价散购。百团大购——团购搜索引擎，是一个聚合信息的平台，在第一时间捕捉各城市的团购、打折、优惠等信息，涵盖了餐厅、影剧院、酒吧、美发美体、KTV、夜店、户外运动、服饰、化妆品等众多领域。在这里你可以尽情享受团购带来的便利和乐趣。在百团大购的网站上（http://www.buy-tuan.com/）首先找到你所在的城市，如果是有目的的购买，可以根据购买物品分类查询，或许暂时没有明确的目标，只想了解最高折扣的活动是什么，那么就可以根据价格进行排序，你所需要的信息就立马会出现在你的眼前，非常的省时省力，不妨登陆试试。3DSFPXZGBV7J feedsky

Taking full advantages of pdfLaTeX — eps figure solution

Jeffye — Mon, 22 Feb 2010 18:51:33 +0000

Advantages of pdfLaTeX

LaTeX users generate postscript output using dvips. An alternative is to use pdfTeX to generate PDF files directly. The PDF format offers a number of advantages over postscript:

Smaller uncompressed file sizes. Much more efficient bitmap inclusion. Availability of hyperlinks. Better accessibility for inexperienced users. Adobe’s Acrobat reader offers facilities for electronic presentations Limitation of pdfTeX

1. postscript figures cannot [...]

latex 中文支持script ＆ samples — memos

Jeffye — Mon, 22 Feb 2010 17:21:02 +0000

介绍如何在ubuntu 下按章cjk 支持，一下脚本在ubuntu 9.10 + kile 下测试好使。

latex 下安装中文支持，需要安装一系列宏包，然后拷贝生成字体什么的，甚是繁琐。一步抄作出问题，会浪费很多时间。

不如写成一个script， shell 脚本。出问题，或机器重装，运行此脚本即可，一劳永逸。

备忘。脚本下载：install_cjk

BibTeX & “undefined control sequence”

Jeffye — Fri, 12 Feb 2010 00:48:41 +0000

If the tex and bib files are setup correctly, then running LaTeX followed by BibTeX will produce a bbl file (in the same directory as the tex and bib files). It is from the bbl file that LaTeX will insert the references into the document.

Open the bbl file with a text editor. If it looks [...]
