## 万事开头难

1. 创业之初，凡事艰难。有人放弃，有人坚持，我们都感觉压力重重，事情不好做，成果不好出，那老板岂不是顶着更大的压力。前几天看了DLX师兄的一篇博文 http://dlx2708.wordpress.com/2011/06/15/career-life-family/ 论事业、家庭和生活的取舍，对于老板来说，应该是career = life > family吧。曾经有一次，我们一群人和老板吃饭，问他有那么多事情，能忙得过来吗，他说：“忙不过来。” 又问：“周末回家吗？” 他回答道：“周末必须有一天回家。” 正当我们觉得老板还是蛮顾家的时候，他又说：“周末带孩子的保姆会请假一天，我不得不回去。” 这句话之后，只能惊叹和佩服老板为科研工作的热情和献身精神了。有了这样的热情和献身精神，创业之初的重重压力，对于老板来说，也就是浮云了吧，由此可以看出，我们感觉到压力和困难重重的时候，就是我们最缺乏工作热情的时候。

2. 不能频繁的改行换业。换个行业，换个领域，就得从头摸索，从零开始。 现在真是隔行如隔山，不可能同时在多个领域都成为内行，特别是做research，在一个领域做久了做深了，想要涉入另一个领域并且快速做到最先进的水平，很难。不过趁着年轻，能通过转一两次行业，换一两次领域能找到自己的内心所属的事业领域，并且确立下来开始为之奋斗还是很值得的。

De-mystifying Good Research and Good Papers

By Fei-Fei Li, 2009.03.01

1000+ computer vision papers get published every year!

Only 5-10 are worth reading and remembering!

Since many of you are writing your papers now, I thought that I’d share these thoughts with you. I probably have said all these at various points during our group and individual meetings. But as I continue my AC reviews these days (that’s 70 papers and 200+ reviews — between me and my AC partner), these following points just keep coming up. Not enough people conduct first class research. And not enough people write good papers.

– Every research project and every paper should be conducted and written with one singular purpose: *to genuinely advance the field of computer vision*. So when you conceptualize and carry out your work, you need to be constantly asking yourself this question in the most critical way you could – “Would my work define or reshape xxx (problem, field, technique) in the future?” This means publishing papers is NOT about “this has not been published or written before, let me do it”, nor is it about “let me find an arcane little problem that can get me an easy poster”. It’s about “if I do this, I could offer a better solution to this important problem,” or “if I do this, I could add a genuinely new and important piece of knowledge to the field.” You should always conduct research with the goal that it could be directly used by many people (or industry). In other words, your research topic should have many ‘customers’, and your solution would be the one they want to use. Read more…

## 卖萌的大牛你桑不起啊—记CVPR2011一篇极品文章[zz]

CVPR2011正在如火如荼的进行中，在网上能看到的部分文章中，我终于找到一篇让我眼前冒光的文章。虽然，其实，也许，主要的理由是我好不容易能看懂一篇。不过，这并不妨碍该文章定会成为今年CVPR的一朵奇葩这件事。不过它肯定拿不了best paper啦，因为它只是篇poster，但我猜也许是组委会认为如果让他们当oral，大牛现场卖萌会雷死观众，并可能引起大面积恐慌。

The authors would like to thank the Eyjafjallajokull volcano as well as the wonderful kirs at the Buvette in Jardin du Luxembourg for the motivation (former) and the inspiration (latter) to write this paper. “作者要感谢埃Eyjafjallajokull的火山（就是2010年冰岛那个倒霉的让欧洲航线大面积瘫痪的火山）以及Buvette in Jardin du Luxembourg（法国一个酒吧）的美味基尔酒，前者给了我们写作的动机，而后者给了我们灵感。”我猜测是那个时候他们在法国开会，结果被火山给关在那儿了，几个无聊的人只好跑去酒吧喝酒，于是在酒精的刺激下想出了这个题目。唉，大牛就是大牛，这种时候都能搞出这样一篇文章，让我等草民怎么活啊，以后天天去喝酒好了。

Disclaimer: No graduate students were harmed in the production of this paper. Authors are listed in order of increasing procrastination ability.

## LaTeX – Multiline equations, systems and matrices[zz]

Series on Blogging with LaTeX

This is the 3rd post in the series. Previous ones:

Many of the examples shown here were adapted from the Wikipedia articleDisplaying a formula, which is actually about formulas in Math Markup.

Multiline Equations

You can present equations with several lines, using the array statement. Inside its declaration you must :

• Define the number of columns
• Define column alignment
• Define column indentation
• Indicate column separator with & symbol &

Example: {lcr} means: 3 columns with indentations respectively leftcenter andright

\begin{array}{lcl} z & = & a \\ f(x,y,z) & = & x + y + z \end{array}

$\begin{array}{lcl} z & = & a \\ f(x,y,z) & = & x + y + z \end{array}$

\begin{array}{rcr} z & = & a \\ f(x,y,z) & = & x + y + z \end{array}

$\begin{array}{rcr} z & = & a \\ f(x,y,z) & = & x + y + z \end{array}$

## Latex字体设置zz

LaTeX的每种字体有5种属性：编码、族，形状，系列和尺寸。

１）形状指的是倾斜和高矮。
\upshape 切换成直立的字体
\itshape 切换成意大利斜体
\slshape 切换成成为 slanted 的斜体
\scshape 切换成小体大写

２）系列是指字体的宽度和权重。权重刻画了笔画的粗细。
\mdseries 切换到中等权重
\bfseries 切换到粗体

\begin{upshape}

\end{upshape}

slanted斜体： \textsl{文本}
