制作u盘linux启动盘

前几天电脑坏了，想弄个linux启动盘应急修复一下，最后虽然还是没派上用场，但是至少启动盘弄出来了，在此记录一下。

需要的工具有
syslinux, 可以从http://www.kernel.org/pub/linux/utils/boot/syslinux/下载一个可以启动的linux映像，为了弄在U盘上，我选择了不到6M的ttylinux

由于是linux坏了，以下操作我都是在windows中进行的

1.解压syslinux
2.插入U盘
3.把linux映像解压到u盘，注意是解压不是拷贝
4.运行syslinux -sfma
5.由于ttylinux的映像是isolinux映像，所以应该做一些修改，把U盘里isolinux目录改名为syslinux,再把里面的isolinux.cfg改名为syslinux.cfg

这样就ok了，其中第5步我花了好久才悟出来
另外syslinux压缩包里也有linux版本

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

[转] UTF-8 and Unicode FAQ for Unix/Linux

这几天,这个东西把我搞得很头疼而且这篇文章好像太大了,blogger自己的发布系统不能发只好用mail了 //原文 http://www.cl.cam.ac.uk/~mgk25/unicode.html UTF-8 and Unicode FAQ for Unix/Linux by Markus Kuhn This text is a very comprehensive one-stop information resource on how you can use Unicode/UTF-8 on POSIX systems (Linux, Unix). You will find here both introductory information for every user, as well as detailed references for the experienced developer. Unicode has started to replace ASCII, ISO 8859 and EUC at all levels. It enables users to handle not only practically any script and language used on this planet, it also supports a comprehensive set of mathematical and technical symbols to simplify scientific information exchange. With the UTF-8 encoding, Unicode can be used in a convenient and backwards compatible way in environments that were designed entirely around ASCII, like Unix. UTF-8 is the way in which Unicode is used under Unix, Linux, and similar systems. It is now time to make sure that you are well familiar ...

Moving Items Along Bezier Curves with CSS Animation (Part 2: Time Warp)

This is a follow-up of my earlier article. I realized that there is another way of achieving the same effect. This article has lots of nice examples and explanations, the basic idea is to make very simple @keyframe rules, usually just a linear movement, then use timing function to distort the time, such that the motion path becomes the desired curve. I'd like to call it the "time warp" hack. Demo See the Pen Interactive cubic Bezier curve + CSS animation by Lu Wang ( @coolwanglu ) on CodePen . How does it work? Recall that a cubic Bezier curve is defined by this formula : \[B(t) = (1-t)^3P_0+3(1-t)^2tP_1+3(1-t)t^2P_2+t^3P_3,\ 0 \le t \le 1.\] In the 2D case, \(B(t)\) has two coordinates, \(x(t)\) and \(y(t)\). Define \(x_i\) to the be x coordinate of \(P_i\), then we have: \[x(t) = (1-t)^3x_0+3(1-t)^2tx_1+3(1-t)t^2x_2+t^3x_3,\ 0 \le t \le 1.\] So, for our animated element, we want to make sure that the x coordiante (i.e. the "left" CSS property) is \(...
