One may learn and use Lisp in the same manner as other traditional
programming languages - by creating text based programs with an
editor.
Lisp also allows programs to be represented as data. There are
functions to evaluate (eg. interpret) programs
and to compile programs. Unlike other languages, the representation
of programs which is given to these functions is not text, but a
list of program expressions.
The Lisp reader is a separate function which converts text to these
expression data. This distinction is invisible most of the time.
However, by changing the reader, one can change the syntax of
the program text, without changing its semantics -
i.e. without changing how it is evaluated or compiled.
The default printer automatically prints lisp data using the
standard syntax.
The default configuration of the reader and printer is actually
the only part of Lisp that uses the syntax. Everything else uses the
expression representation of programs.
Some people like Lisp syntax. Others don't, and redefine the LISP
acronym to stand for "Lots of Irritating, Silly Parentheses." If you
tend to agree, it is useful to recognize that you can also change the
reader to a syntax that you like better.
Here's how the inventor of Lisp explained it in "History of Lisp", 1978:
This internal representation of symbolic information gives up the
familiar infix notations in favor of a notation that simplifies the
task of programming the substantive computations, e.g., logical
deduction or algebraic simplification, differentiation or
integration. If customary notations are to be used externally,
translation programs must be written. Thus LISP programs use a prefix
notation for algebraic expressions, because they usually must
determine the main connective before deciding what to do next. In
this, LISP differs from almost every other symbolic computation
system. ... This feature probably accounts for LISP's success in
competition with these languages, especially when large programs have
to be written. The advantage is like that of binary computers over
decimal--but larger.
... Another reason for the initial acceptance of awkwardnesses in the
internal form of LISP is that we still expected to switch to writing
programs as M-expressions [infix format]. The project of defining
M-expressions precisely and compiling them or at least translating
them into S-expressions was neither finalized nor explicitly
abandoned. It just receded into the indefinite future, and a new
generation of programmers appeared who preferred internal notation to
any FORTRAN-like or ALGOL-like notation that could be devised.
... One can even conjecture that LISP owes its survival specifically
to the fact that its programs are lists, which everyone, including me,
has regarded as a disadvantage. Proposed replacements for LISP
... abandoned this feature in favor of an Algol-like syntax, leaving
no target language for higher level systems.
The language Dylan, developed by
Apple, Carnegie-Mellon University, and Harlequin, can be viewed as a
C-like syntax for Lisp.
The actual Common Lisp syntax is defined as follows:
- Whitespace is ignored.
- In general, case is ignored by automatically translating
everything to upper case, except within strings or when specifying
individual characters as data. This behavior can be changed by the user.
- The first one or two characters of each expression define how the
expression is to be read:
- The character
" reads the text up to the next "
as a string object.
- The character
( reads the text up to the next )
as a list object.
- The character
# is used to introduce a two-character
dispatch:
-
#\ reads the remaining expression as a character object.
Characters can have names. Examples: #\a #\A
#\Return #\Control-G .
-
#* reads the remaining expression as a bit
vector. Example: #*1001
-
#( reads the remaining expression (terminated by a
closing ) ) as a vector. Example: #(1 2 3)
-
#nA( reads the remaining expression (terminated by a
closing ) ) as an n-dimensional array. Examples:
#1A(1 2 3 4) #2A((1 2) (3 4)) .
-
#S(name reads the remaining expression (terminated by a
closing ) ) as a structure object of type name. Example:
#S(point :x 1 :y 2) .
- There are a few others as well, and more can be defined by the user.
- There are a few other single character dispatching characters,
and more can be defined by the user.
- Everything else is either a number of a symbol. The reader is
smart enough to recognize all the usual representations for integer,
rational or floating point numbers. The base for rational numbers can
be specified by the user.
The internal expression representation for programs is simply this:
- Symbols are names of variables.
- Everything else that is not a list is simply treated as literal
data.
- A list is either a special operation or a function call:
- If the first item in the list is a symbol recognized as either a
system-defined or user-defined special operator, the rules for that
operator are followed to evaluate the list. There are special
operators defined for defining functions, classes, variables, etc., as
well as to control evaluation within a function (
if ,
assignment, etc.).
- Otherwise the first item names a function, and the rest of the
items in the list are arguments to the function.
That's it. No predence ordering. No statements.

Michael Schumacher's wife on the F1 legend: "He is in the very best of hands"
by Louis ShawMichael Schumacher is regarded as one of the greatest Formula 1 drivers of all time. The German racer won seven World Championships, which is the most any driver has ever won. Tragically, the Formula 1 legend suffered a serious head injury whilst skiing in 2013 and for the first time since then his wife, Corinna Schumacher, has spoken about it.
"He did everything for me. I will never forget who I have to thank. That would be my husband Michael," Corinna said to SHE magazine when asked about life before her husband's accident.
"You can be sure that he is in the very best of hands and that we are doing everything humanly possible to help him.
"Please understand if we are following Michael's wishes and keeping such a sensitive subject as health, as it has always been, in privacy.
"At the same time, we say thank you very much for your friendship and wish you a healthy and happy year."
Schumacher's condition is still uncertain but it is thought he is suffering the effects of serious brain damage. He will be proud of how his son Mick Schumacher is performing in Formula 2 and will hope that Formula 1 success is in his blood.

My name is + David Rubert from Castellón de la Plana, Spain. This lesson covers week 1 of the Coursera course Introduction to Music production. I have choosen to present the Type and usage of important studio cables. I hope you find it interesting.
They are a fundamental part of the music production process. Allow us to interconnect the microphones, instruments, or any other audio source to our audio interface, amplifier, active monitors, etc.
We can find two basic types of audio cables:
Analog and Digital.
These are a fundamental type of cables, allow us to connect input sources like microphones or instruments to our interface or amplifier.
There are three main types of analog cables, identified by their connectors:
TS (tip-sleeve) cable has a cylindrical shape connector with 2 contacts, and it's a single conductor cable. The tip carries the main signal and the sleeve acts as an shield.
Mainly used for instruments connection, it's affected by noise. We must use it as shorter as possible.
TRS (tip-ring-sleeve) cable is a two conductor cable with a shield. Very similar phisically with the TS cable.
Can be used as an stereo cable (carrying two separate signals), or as a balanced configuration, which only carries one audio signal but cancels noise.
This type of cable connector, like the TRS one, has 3 pins on his end, but its connector is designed specifically for microphones, with a very useful locking system.
Like the TRS cables, these are the recommended cables to connect long-distance separated devices.
It's possible to connect an unbalanced cable with a balanced one, using a middle device called direct box.
For what would we want this for? Easy, it would allow us to make a long distance connection of an unbalanced connected deviced .
Eight inch stero connector. It's the same connector as its big brother one, the TRS that we saw before.
RCA. It's an unbalanced cable used to connect home consumer devices. If you connect one of this to your pro gear, remember that the consumer devices work at -10dBv.
Digital connectors allow us to interconnect digital devices, passing digital signals between them. We can find these types of digital connectors:
S/PDIF. Trasmits the digital signal over a coaxial cable or a optical fiber cable (TosLINK).
MIDI. Trasmits digital data (MIDI DATA) over a 5 contacts cable (DIN connector).
I'm not a professional of audio but a learning enthusiat so I expect that the presentation has been pleasant to you. Thanks for watching, evaluating and critiquing it. See you later on the forums!.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.
The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters,
as opposed to using 'Content here, content here', making it look like readable English. Many
desktop publishing packages and web page editors now use Lorem Ipsum as their default model text,
and a search for 'lorem ipsum' will uncover many web sites still in their infancy

This dish is called Leeli Kolmi Ni in Thailand.
Heat the oil in a large heavy-based pan with a lid. Add the onion and cook until translucent.
Add the garlic, ginger and green chillies and cook for two minutes, taking care not to let them brown.
Add the turmeric and cook for a few seconds, then pour in the coconut milk. Bring slowly to the boil, stirring right from the bottom of the mixture.
Season with salt, then add the cardamom, cloves, curry leaves and cinnamon. Simmer for a couple of minutes, until the mixture has thickened slightly, then add the coriander and cook for another minute or two.
Add the prawns and cook for 2-4 minutes, depending on their size. Cover the pan, remove from the heat and set aside for about five minutes. The prawns will continue to cook in the residual heat of the curry (more cooking on the stove will spoil the prawns by overcooking).
Serve with steamed jasmine rice and a fresh onion salad.


Stacking Boxes
问题描述 :
Consider an n-dimensional “box” given by its dimensions. In two dimensions the box (2,3) might represent a box with length 2 units and width 3 units. In three dimensions the box (4,8,9) can represent a box 4*8*9(length, width, and height). In 6 dimensions it is, perhaps, unclear what the box (4,5,6,7,8,9) represents; but we can analyze properties of the box such as the sum of its dimensions.
In this problem you will analyze a property of a group of n-dimensional boxes. You are to determine the longest nesting string of boxes, that is a sequence of boxesb1,b2,..bk such bi,that each box nests in box b(i+1)( 1≤i<k) .
A box D = ( d1,d2,…dn ) nests in a box E = ( e1,e2,…en ) if there is some rearrangement of the di, such that when rearranged each dimension is less than the corresponding dimension in box E. This loosely corresponds to turning box D to see if it will fit in box E. However, since any rearrangement suffices, box D can be contorted, not just turned (see examples below).
For example, the box D = (2,6) nests in the box E = (7,3) since D can be rearranged as (6,2) so that each dimension is less than the corresponding dimension in E. The box D = (9,5,7,3) does NOT nest in the box E = (2,10,6,8) since no rearrangement of D results in a box that satisfies the nesting property, but F = (9,5,7,1) does nest in box E since F can be rearranged as (1,9,5,7) which nests in E.
Formally, we define nesting as follows: box D = (d1,d2,….dn ) nests in box E = ( e1,e2,….en ) if there is a permutation π of 1..n such that ( ) “fits” in ( e1,e2…..en ) i.e., if for all 1≤i≤n.
输入:
This line is followed by k lines, one line per box with the n measurements of each box on one line separated by one or more spaces. The i(th) line in the sequence ( 1<=i<=k ) gives the measurements for i(th) the box.
There may be several box sequences in the input file. Your program should process all of them and determine, for each sequence, which of the k boxes determine the longest nesting string and the length of that nesting string (the number of boxes in the string).
In this problem the maximum dimensionality is 10 and the minimum dimensionality is 1. The maximum number of boxes in a sequence is 30.
输出:
The boxes should be numbered according to the order in which they appeared in the input file (first box is box 1, etc.).
If there is more than one longest nesting string then any one of them can be output.

#include <iostream> #include <stdio.h> #include <string.h> #include <queue> #include <math.h> #include <algorithm> using namespace std; double p[102][2]; double map[102][102]; double dist[102]; int visited[102]; double r = 16.7/2; //ai-经度,bi-纬度 double dis(double a1,double b1,double a2,double b2) { a1 = acos(-1) * a1/180; b1 = acos(-1) * b1/180; a2 = acos(-1) * a2/180; b2 = acos(-1) * b2/180; return r * acos(cos(a1 - a2) * cos(b1) * cos(b2) + sin(b1) * sin(b2)); } int main() { #ifndef ONLINE_JUDGE freopen("in.txt","r",stdin); #endif int n; int t = 0; while(scanf(" %d",&n)!=EOF && n!=0) { t++; for(int i = 0; i<n; i++) { scanf(" %lf %lf",&p[i][0],&p[i][1]);//经度、纬度 } memset(map,0,sizeof(map)); for(int i = 0; i<n; i++) { for(int j=i+1; j<n; j++) { map[i][j] = map[j][i] = dis(p[i][0],p[i][1],p[j][0],p[j][1]); } } memset(dist,0x7f,sizeof(dist)); memset(visited,0,sizeof(visited)); dist[0] = 0; double sum = 0; for(int i=0; i<n; i++) { int k = 0; double min = 0x7f; //最短的dist[k] for(int j=0; j<n; j++) { if(visited[j] == 0 && dist[j]<min) { min = dist[j]; k = j; } } visited[k] = 1; sum += min; //松弛该点 for(int j = 0; j<n; j++) { if(dist[j] > map[k][j]) { dist[j] = map[k][j]; } } } printf("Case %d: %.2lf miles\n",t,sum); } return 0; }

对，就是把这32位当成一个长度为32的数组
如果两个序列的最后字符不匹配（即X [M-1]！= Y [N-1]）
L（X [0 .. M-1]，Y [0 .. N-1]）= MAX（L（X [0 .. M-2]，Y [0 .. N-1]），L（X [0 .. M-1]，Y [0 .. N-1]）
这里写错了吧。
这个还不错
第23行：
hash = -1是否应该改成hash[s ] = -1
因为是要把从字符串s的start位到当前位在hash中重置
修改提交后能accept，但是不修改居然也能accept
这个应该是比较简单的解法了，如果有更好的办法可以告诉我
这个分析相当全面，经典！
我还有个问题想请教一下，就是感觉对于新手来说，递归理解起来有些困难，不知有没有什么好的方法或者什么好的建议？
全是智力分析的题
2的64次方是多少？ 这到底是在考什么啊
示例程序中的代码不够稳健，没有考虑到输入了非法字符或者不合理输入的情况。
学习了
已修改。一些字符在编辑的时候转义了


This is an experimental component to define a Real parameter in the diagram layer. The idea is to drag the icon from the package browser into the diagram layer. Then a window pops up in which the properties of this parameter can be defined (such as the default value). The name and default value of the parameter are displayed in the icon of this component. Whenever clicking on it, the dialog to change parameter settings pops-up.
In Dymola, the described property is not fully available. Currently, when dragging this component in the diagram layer, a dialog pops up in which the properties of the parameter can be defined. However, afterwards, the parameter is not visible in the diagram layer. Making it visible requires to go into the text layer and add an annotation with the component size, resulting for example in:
parameter StateGraph.Temporary.SetRealParameter name = 2 annotation(Placement(transformation(extent={{-10,-10},{10,10}})));
This change makes the parameter icon visible in the diagram layer. However, clicking on this icon has no effect. Changing parameter properties, such as the default value, still requires to go in to the text layer.
type SetRealParameter = Real;


Speedometer tests a browser's Web app responsiveness by timing simulated user interactions.
This benchmark simulates user actions for adding, completing, and removing to-do items using multiple examples in TodoMVC. Each example in TodoMVC implements the same todo application using DOM APIs in different ways. Some
call DOM APIs directly from ECMAScript 5 (ES5), ECMASCript 2015 (ES6), ES6 transpiled to ES5, and Elm transpiled to ES5. Others use one of eleven popular JavaScript frameworks: React, React with Redux, Ember.js,
Backbone.js, AngularJS, (new) Angular, Vue.js, jQuery, Preact, Inferno, and Flight. Many of these frameworks are used on the most popular websites in the world, such as Facebook and Twitter. The performance of these types
of operations depends on the speed of the DOM APIs, the JavaScript engine, CSS style resolution, layout, and other technologies.
Although user-driven actions like mouse movements and keyboard input cannot be accurately emulated in JavaScript, Speedometer does its best to faithfully replay a typical workload within the demo applications. To make the
run time long enough to measure with the limited precision, we synchronously execute a large number of the operations, such as adding one hundred to-do items.
Modern browser engines execute some work asynchronously as an optimization strategy to reduce the run time of synchronous operations. While returning control back to JavaScript execution as soon as possible is worth
pursuing, the run time cost of such an asynchronous work should still be taken into a holistic measurement of web application performance. In addition, some modern JavaScript frameworks such as Vue.js and Preact call into
DOM APIs asynchronously as an optimization technique. Speedometer approximates the run time of this asynchronous work in the UI thread with a zero-second timer that is scheduled immediately after each execution of
synchronous operations.
Speedometer does not attempt to measure concurrent asynchronous work that does not directly impact the UI thread, which tends not to affect app responsiveness.
Note: Speedometer should not be used as a way to compare the performance of different JavaScript frameworks as work load differs greatly in each framework.
