Blockchain CSP

1.

there are many kinds of this. Here are some common ones. Compare the programming language to a car:

ADA is a tank that is extremely ugly but never fails

C is a racing car. It can run faster than expected, but it breaks down every 50 miles

COBOL claims to be a car, but no self respecting driver would admit that he has ever driven it

C # is a family station wagon in a competitive mode. Once you've opened it, you won't use the procts of other competitors

C + + is a high-powered version of the C-car, which provides dozens of extra features and breaks down every 250 miles, but when it does go wrong, no one can find out what's wrong

Eiffel is a car with French accent driving instructions. He will help you find your mistakes quickly and learn from them, but if you dare to argue with him, he will scold you and throw you out of the car[ From Daniel Prager, slightly modified]

Erlang is a team that will work with each other to get you wherever you want to go. It's still a bit of practice to control a car with each foot, but once you've learned it, you can drive them to places that are hard to reach in other ways. Also, you use so many cars, so even if some of them break down, there's nothing to worry about

forth is a car that you assembled with your own kit. Your car doesn't have to look or function the same as others. However, the forth model can only go backwards

[comment on digg.com, from 256 byteram (I can't help adding it):]

for love if honk then Sorry, I really don't know what that means...)

FORTRAN is a very primitive car. It can run very fast if you are always on a completely straight road. It is said that learning to drive a FORTRAN car will make you unable to drive other models of cars any more

java

java is a family station wagon. It's easy to drive, and it won't be too fast to hurt yourself

version 1: Haskell is a car with extremely elegant and beautiful design. It is said that it can drive to very extreme terrain. When you try to drive it, it's not really going along the road; In fact, it constantly copies itself and the road. After each successful , the car will be a little farther on the road than the last one. It should still be possible to drive it in the traditional way, but your math skills are not enough to find this way

version 2: Haskell is not a real car, it is an abstract machine that can tell you in detail what the driving process should be like, if you like. You have to put this abstract machine into another real machine to start it. Don't ask how the real machine works. There is also a way, you can use many abstract machines to build another abstract machine, and then give it to the actual machine, so that you can complete your journey one by one[ Monadic version]

version 1: LISP looks like a car, but with enough modification, it can become a very effective aircraft or submarine

version 2: at first, it doesn't look like a car at all. You can see people driving it around all the time. Finally one day you decide to learn more about it, and then you realize that it's actually a car that can make more cars. You told your friends about this discovery, but they all laughed and said that the cars looked so strange. You still have one in the garage, looking forward to driving it on the road some day[ From Paul Tanimoto]

Mathematica is a well-designed car. It draws a lot of lessons from LISP cars, but it doesn't even give it any e praise. It can calculate the most efficient path to the destination through the equation, but it costs a lot of money

is a short-distance station wagon designed for novices. It usually goes to the places where mathmatica cars often go. In those places, the car is very comfortable to drive, but as long as you deviate from the route, even a little, it will become very difficult to control, so that many snobbish drivers do not recognize it as a car at all

Ocaml is a very sexy European car. It's not as fast as C, but it never breaks down, so as a result, it takes you less time to get to your destination. But because this is France, all the controls are not where they should be

Perl should be a cool car, but the driver's manual is hard to understand. In addition, even if you can find a way to drive a Perl car, you can't drive someone else's Perl car

PHP is an Oscar Mayer wienermobile, which is very strange and difficult to drive, but everyone still wants to drive it[ Cosmonjustice from digg.com]

version 1: Prolog is fully automatic: you tell it what your destination looks like, and then the rest of the driving is done[ Paul Graham added:] However, in most cases, it takes about the same amount of time to confirm your destination as if you were driving directly there

version 2: Prolog is equipped with a unique trial and error GPS system. On the way to the destination, it will drive straight ahead. If it comes to a dead end, it will turn back and try another way, and so on, until the destination[ I forgot who suggested this one]

Python is a great car for beginners, even without a driver's license. Unless you want to drive super fast or go to dangerous places, you may never use another car

ruby is the result of a collision among Perl, Python and Smalltalk. A Japanese pilot found the pieces of these cars and put them together into a car. Many drivers think it's better than the three cars put together. However, some drivers will complain that many of the controllers of ruby car are repetitive, even three copies, and these repetitive controllers are slightly different in some special cases, which will make the car more troublesome to drive. According to legend, the redesign work is already in progress

Smalltalk is a small car, originally designed for those who want to learn to drive, but because it is so well designed, even those experienced drivers like to drive it. It's not very fast, but you can take down any of its parts to make it more in line with your expectations. The odd thing is that you don't actually drive it, you just send a message to it to go somewhere, and then it either drives by or tells you it doesn't understand what you're talking about

version 1: assembly is just an engine. You have to build your own car and refuel it manually as it runs. But as long as you're careful, it can move like a bat out of hell

version 2: Compilation: you are the car

if programming language is a weapon:

C language is M1 garland rifle, very old but reliable

C + + is a double truncheon. It's very strong and attractive to wave, but it needs years of training to master. Many people want to use other weapons

java is a M240 universal clip type automatic machine gun. Sometimes its clip is round, but sometimes it is not. If it is not, when you fire, you will encounter NullPointerException, and the gun will explode and you will be killed

Scala is a variant of M240 universal machine gun, but its manual is written in an incomprehensible dialect, which many people suspect is just some dreamtalk

JavaScript is a sword, but it has no hilt

go language is a self-made "if err= "Nil" starting gun, after each launch, you have to check whether it is really launched

rust language is a 3D printed gun. It may come in handy in the future

Bash is a very difficult hammer. When you swing it, you will find that everything looks like nails, especially your fingers

ruby is a ruby inlaid sword. People usually use it because it looks gorgeous

PHP is a water pipe. You usually connect one part of it to the exhaust pipe of the car and insert the other end into the window of the car. Then you sit in the car and start the engine

Mathematica is a kind of earth's low orbit Particle Cannon. It may be able to do amazing things, but only people who can afford it can use it

c#is a kind of powerful laser cannon, which is mounted on a donkey. If it is unloaded from the donkey, it seems that it can not emit laser

Prolog language is an artificial intelligence weapon. If you tell it what to do, it will follow suit, but after that, it will get some terminators out and burn your house

LISP language is a razor with many styles. Only those who seek stimulation and danger will use it

I hope I can help you, thank you
