李白
弃我去者，昨日之日不可留；
乱我心者，今日之日多烦忧。
长风万里送秋雁，对此可以酣高楼。
蓬莱文章建安骨，中间小谢又清发。
俱怀逸兴壮思飞，欲上青天揽明月。
抽刀断水水更流，举杯销愁愁更愁。
人生在世不称意，明朝散发弄扁舟。
【诗文解释】
弃我而去的昨天已不可挽留，扰乱我心绪的今天使我极为烦忧。万里长风吹送南归的鸿雁，面对此景，正可以登上高楼开怀畅饮。你的文章就像蓬莱宫中储藏的仙文一样高深渊博，同时还兼具建安文学的风骨。而我的诗风，也像谢朓那样清新秀丽、飘逸豪放。我们都满怀豪情逸兴，飞跃的神思像要腾空而上高高的青天，去摘取那皎洁的明月。然而每当想起人生的际遇，就忧从中来。好像抽出宝刀去砍流水一样，水不但没有被斩断，反而流得更猛了。我举起酒杯痛饮，本想借酒排遣烦忧，结果反倒愁上加愁。啊！人生在世竟然如此不称心如意，还不如明天就披散了头发，乘一只小舟在江湖之上自在地漂流。
【词语解释】
高楼：即题“谢朓楼”，南齐诗人谢朓官宣城（即宣州，今属安徽）太守时所建。
蓬莱：指秘书省。李白族叔李云官秘书校书郎。
清发：清新秀丽。
逸兴：超逸的意兴。
散发：不戴冠簪子。指散漫无拘束。
扁舟：小船。弄扁舟，指归隐江湖。
【诗文赏析】
身在浊世，烦恼剪不断理还乱。当诗人的理想与黑暗的现实产生矛盾之时却又无法发泄。可贵的是作者虽然精神上承受着苦闷的重压，但却并未因此放弃对理想的追求。全诗灌注了慷慨豪迈的情怀，正如在悲怆的乐曲中奏出了高昂乐观的音调。
诗中蕴含了强烈的思想感情，如奔腾的江河瞬息万变，波澜迭起，和艺术结构的腾挪跌宕、跳跃发展完美结合。

First include the “listings”-package into your document:

\usepackage{listings}

Basics

Now you have basically two possibilities. Either you type/copy your source code directly into the Latex document:

\begin{lstlisting}
place your source code here
\end{lstlisting}

The other possibility is to directly include the source file:

\lstinputlisting{filename.java}

This is particularly useful if you are still editing your source code. Obviously, Latex will always include the latest version of the source while generating the PDF-file.

Supported languages

The listings package does not only support java source code, but there is an exhaustive list of languages which are known to the package:
ABAP (R/2 4.3, R/2 5.0, R/3 3.1, R/3 4.6C, R/3 6.10), ACSL Ada (83, 95), Algol (60, 68), Ant, Assembler (x86masm), Awk (gnu, POSIX), bash, Basic (Visual), C (ANSI, Handel, Objective, Sharp), C++ (ANSI, GNU, ISO, Visual), Caml (light, Objective), Clean, Cobol (1974, 1985, ibm), Comal 80, csh, Delphi, Eiffel, Elan, erlang, Euphoria, Fortran (77, 90, 95), GCL, Gnuplot, Haskell, HTML, IDL (empty, CORBA), inform, Java (empty, AspectJ), JVMIS, ksh, Lisp (empty, Auto), Logo, make (empty, gnu), Mathematica (1.0, 3.0), Matlab, Mercury, MetaPost, Miranda, Mizar, ML, Modula-2, MuPAD, NASTRAN, Oberon-2, OCL (decorative, OMG), Octave, Oz, Pascal (Borland6, Standard, XSC), Perl,PHP, PL/I,Plasm, POV,Prolog, Promela,Python, R,Reduce, Rexx,RSL, Ruby, S (empty, PLUS), SAS, Scilab, sh, SHELXL, Simula (67, CII, DEC, IBM), SQL, tcl (empty, tk), TeX (AlLaTeX, common, LaTeX, plain, primitive), VBScript, Verilog, VHDL (empty, AMS), VRML (97), XML, XSLT.

Custom code formatting

You can customise the way how your code is displayed by using:

\lstset{...}


The following is a list of parameters, which can be used inside the previous command

language=Octave -> choose the language of the code
basicstyle=\footnotesize -> the size of the fonts used for the code
numbers=left -> where to put the line-numbers
numberstyle=\footnotesize -> size of the fonts used for the line-numbers
stepnumber=2 -> the step between two line-numbers.
numbersep=5pt -> how far the line-numbers are from the code
backgroundcolor=\color{white} -> sets background color (needs package)
showspaces=false -> show spaces adding particular underscores
showstringspaces=false -> underline spaces within strings
showtabs=false -> show tabs within strings through particular underscores
frame=single -> adds a frame around the code
tabsize=2 -> sets default tab-size to 2 spaces
captionpos=b -> sets the caption-position to bottom
breaklines=true -> sets automatic line breaking
breakatwhitespace=false -> automatic breaks happen at whitespace
morecomment=[l]{//} -> displays comments in italics (language dependent)

If you are using several parameters, they have to be separated by commas.
Example:

\lstset{numbers=left, stepnumber=2, frame=single,}


You might want to have a caption as well as reference the listing later:

\lstset{language=Java, caption=Descriptive Caption Text, label=DescriptiveLabel}


For an exhaustive list of available options to customize your included source code, refer to the documentation on CTAN.

Tricks

The following will draw a frame around your source code with a blue shadow (you will need the color-package).

\lstset{frame=shadowbox, rulesepcolor=\color{blue}}


If you want closed frames on each page, use the following command sequence:

\begin{framed}
\begin{lstlisting}...\end{lstlisting}
or \lstinputlisting{...}
\end{framed}

A long-channel device is generally one whose channel length is greater than 2 um. In this device, the horizontal electric field in the channel induced by the drain voltage and the vertical electric field induced by the gate voltage can be treated independently. However, the channel length of present-day devices is on the order of 0.2 um or less, which is indicated short-channel devices.

There are several effects in these short-channel devices that influence and change the long-channel current-voltage characteristics. One such effect is a variation in the threshold voltage. The value of the threshold voltage is a function of the channel length. This variation must be considered in the design and fabrication of these devices. The threshold voltage also becomes a function of the drain voltage. As the drain voltage increases, the effective threshold voltage decreases. This effect also influences the current-voltage characteristics.

The carrier mobility values are functions of the vertical electric field in the inversion layer. But we have assumed that the carrier mobilities and corresponding process condition parameters are constant. As the gate voltage and the vertical electric field increases, the carrier mobility decreases. This result directly influences the current-voltage characteristics of the device.

Another effect that occurs in short-channel devices is velocity saturation. As the horizontal electric field increases, the velocity of the carriers reaches a constant value and will no longer increase with an increase in drain voltage. Velocity saturation will lower the Vds(sat) voltage value. The drain current also becomes approximately a linear function of the gate voltage in the saturation region rather than the quadratic function of gate voltage in the long-channel characteristics.

Heard before about the cultural shock, but never actually been experienced. Now it is my current status in recent days.

I could even not remember when it was the last time I wrote something here. Actually it was last December I wrote a small story about the mutton soup and my childhood, and it looks like to be quite a long time till now. It really needs to make a decision for me to write something on the blog, and here I come.

Indeed, it has been about half a year, and last time I sat still for writing, it was chilly outside, and at the moment, I am wearing a T-shirt and sweating hard! Comparing to the last term, I am enjoying a quite leisure time now, no too heavy burden, no irritating courses(like microwave engineering), everything goes just up to my taste. I finally can live as I like. On the other side, it is the leisure that drags me down.

Suddenly did I feel lost.

I could not wake up early in the morning now, nor fell asleep during the night. And I am pondering that, it is a fact that, my life used to be directed by some other explicit factors. It is true. When I was kid, my father arranged everything, there was always no need to worry about. Even in my college life, there were always tasks and assignments to be accomplished.  Yet, when all these extorior conditions are striped, I lost my direction. I did not sometimes stop and think about what is the next step. And I understand that now, finally. Words from Tyler Durden ("Fight Club" Directed by David Fincher. Starred by Edward Norton, Brad Pitt) may describe my and even my generation's situation:

"God damn it, an entire generation pumping gas, waiting tables. Slaves with white collars. Advertising has us chasing cars and clothes. Working jobs we hate so we can buy shit we don't need. We're the middle children of history. No purpose or place. We have no Great War. No Great Depression. Our great war is a spiritual war. Our great depression is our lives."

Tyler Durden was right. Our struggle is our lives. Anyway life goes, and we should move on. You can never expect a path directed not by yourself. So I wake up today, in this sunny afternoon.

"And we are all pissed off." 

Lightning kills as many as 2,000 people worldwide every year. Hundreds more people are struck but survive, usually with lingering and debilitating symptoms. Here are some things you can do to avoid electrical storms or decrease your chances of getting struck.

Safety Tips:

• If outside, seek refuge in a car or grounded building when lightning or thunder begins.
• If inside, avoid taking baths, or showers, and washing dishes. Also avoid using landline phones, televisions, and other appliances that conduct electricity.
• Stay inside for 30 minutes after you last see lightning or hear thunder. People have been struck by lightning from storms centered as far as 10 miles (16 kilometers) away.
• If caught outside away from a building or car, stay clear of water bodies and tall objects like trees. Find a low spot or depression and crouch down as low as possible—but don’t lie down on the ground. Lightning can move in and along the ground surface, and many victims are struck not by bolts but by this current.
