Calm, calm, calm.
There are a lot of tasks, that is, 2 days and a half of the time, feel there are a lot of problems to solve, but how they feel slack ... Why do you feel slack ah ... This is not scientific ah. I have to work hard to make a serious effort. Study hard. Try to refuel. Work hard. It's a long time. The opportunity is very good. Is that I have the ability to seize, then I will be OK. I began

"Our design team partners use Skala to test the work in real time on the phone," he said. "We want to make sure our design looks OK on the high quality screen," "light's UX director Jannie Lai explained. 」

This is a very simple operation of the Ui/ux design application.

"wirefram also has a good helper in visual design. "skully's design deputy director Josh Bloom said.
, I do is a student project is just a big job, but in fact same, you design a product or product in a function, always to solve a problem. Even if it is a very small example, you have been a friend punctuate design, the design exists also have his reasons, how did you think you got your final solution? That's what I care about.
Here's a chestnut.

In summary, the component language stack turns to Golang, including the original Python Calicoctl, which is also rewritten with Golang, which, incidentally, is the same as the language stack from Python to Golang, which can be seen in the same cycle as Golan G has a large impact on the container rim,

ObjectiveRecently work on the use of Redis, of course, have used redis,win,linux have used, not system, not in-depth, only a piecemeal, piecemeal, here to tidy up their notes, one to facilitate their own memory, and the peer to provide reference, insufficient errors, please point out, I will see the situation change, haha.What is Redis?
Redis is an open source API that is written in ANSI C, supports the web, can be persisted in memory, key-value databases, and provides multiple language

RABBITMQ is an open source implementation of the AMQP (Advanced Message Queue) developed by Erlang. The emergence of AMQP in fact is also the needs of the masses of people, although in the world of synchronous messaging communication There are many public standards (such as Cobar IIOP, or SOAP, etc. ), but in the asynchronous message processing is not so, Only large enterprises have some commercial implementations (such as Microsoft MSMQ, IBM Websphere MQ, etc.), so in 2006, Cisco, R

This article mainly introduced the Laravel Event System Usage Summary, has certain reference value, now shares to everybody, has the need friend can refer to
The Laravel event provides a simple observer implementation that subscribes to and listens to various events that occur in the application. The event classes are saved in the App/events directory, and the listeners for these events are saved in the App/listeners directory. These directories are created automatically only when you use the A
Bellman-fordThe algorithm solves the single-source shortest path problem in general, and its edge can be negative. The Bellman-ford algorithm can determine if there is a negative ring in the graph and returns a Boolean value if there is a negative ring. Of course, the value of the shortest path is returned if there is no negative ring present.#include #includestring.h>#include#includeusing namespacestd;#defineINF 0x3f3f3f#defineN 11110intDis[n];intS,t,m,n;structpoint{intU,v,w;} P[n];voidBellman
of view, i.e. h (n) =0 nA sequence of nLinear time-invariant systems are divided into two categories: FIR (finite duration impulse response), Infinite duration impulse response (IIR)Due to the form of convolution when H (k) in the infinite interval length is not 0 o'clock, the required input storage units are numerous and cannot be physically implemented. If it is done, it can only be described by the difference equation (with initial seed and recursive relationship can record the entire range)

Each ant colony and apple tree are described by a pair of integer coordinates x and y (−10 000≤ x y ≤10) on a Cartesian plane. All ant colonies and apple trees occupy distinct points on a plane. No three points is on the same line.OutputWrite to the output file n lines. The number written on i-th line denotes the number (from 1 to N) of the apple tree which is connected
