Fortoken miner
Hello, the answer is not easy, hope to adopt, first of all your question is two pieces of content, the issue of digital currency and mining! This is two things, generally need to use mining machine to mine are published and online transactions of digital currency, and the majority of mainstream currency! For example, BTC / eth
4. Singapore law sponsored terms.conditions for public issues token public offering terms, website publicity and disclaimer in accordance with Singapore regulatory regulations

Everything you do is legal and compliant. In addition, after reporting, we are not afraid of MAS to check you. Of course, the most important point is that we can go to the mainstream exchanges
among them, the packaging and promotion of tokens, and the exchanges you go to, are the places that reflect the strength of your currency. The fees for necessary documents mentioned above are not worth mentioning< br />
the bull market is not so fast. Take your time
mining projects can focus on gongxinbao and super energy.

I hope there is a ";" before the ";"
reason: the three segments in the for loop should be separated by semicolons instead of commas
are changed to: for (I = 1; i<= n; I + +) and for (J = 0; j<= i; J + +) running will not report an error
expanding knowledge:
the syntax of for loop in C language:
for (init; condition; increment )
{
statement(s);
The following is the control flow of the for loop: < UL >init will be executed first and only once. This step allows you to declare and initialize any loop control variable. You can also not write any statements here, as long as a semicolon appears
next, we will judge the condition. If true, the body of the loop is executed. If false, the body of the loop is not executed, and the control flow jumps to the next statement immediately following the for loop
after executing the body of the for loop, the control flow jumps back to the above increment statement. This statement allows you to update the loop control variable. The statement can be left blank as long as a semicolon appears after the condition
Thecondition is judged again. If it is true, the loop will be executed, and the process will be repeated (loop the main body, then increase the step value, and then judge the condition again). When the condition becomes false, the for loop terminates
var userResults = [];
query.find({
success: function(results) {
// Do something with the returned AV.Object values
for (var i = 0; i < results.length; i++) {
var object = results[i];
userResults.push(object);
alert(object.id + ' - ' + object.get('playerName'));
}
},
error: function(error) {
alert("Error: " + error.code + " " + error.message);
}
});
console.log(userResults);//控制台的输出结果为空，外部无法用这个方法获取到查询的结果
the Chinese translation of session is "session". When a user opens a web application, a session is generated with the web server. The server uses session to temporarily save the user's information on the server, and the session will be destroyed after the user leaves the website. This kind of user information storage method is more secure than cookie, but session has one defect: if the web server does load balancing, the session will be lost when the next operation request arrives at another server<
cookie
cookie is the data stored in the local terminal. The cookie is generated by the server and sent to the browser. The browser saves the cookie in kV form to a text file in a directory. The next time it requests the same website, it will send the cookie to the server. Since cookies exist on the client, the browser adds some restrictions to ensure that cookies will not be used maliciously and will not occupy too much disk space. Therefore, the number of cookies in each domain is limited
cookies are composed of: name (key), value (value), valid domain (domain), and path (path of domain), which is generally set to global: & quot&# 92;& quot;)、 Failure time, security flag (when specified, the cookie will only be sent to the server (HTTPS) when using SSL connection). The following is a simple example of JS using Cookie:
generate cookie when user login:
document. Cookie = & quot; id="+ result.data[' id']+& quot;; path=/";< br />document.cookie = " name="+ result.data[' name']+& quot;; path=/";< br />document.cookie = " avatar="+ result.data[' avatar']+& quot;; path=/";
when using a cookie, do the following parsing:
var cookie = document.cookie; var cookieArr = cookie.split(";& quot;); var user_ info = {}; for(var i = 0; i < cookieArr.length; i++) {
user_ info[cookieArr[i].split("=& quot;)[ 0]] = cookieArr[i].split("=& quot;)[ 1];< br />}
$('# user_ name'). text(user_ info[' name']);< br />$('# user_ avatar'). attr(" src", user_ info[' avatar']);< br />$('# user_ id'). val(user_ info[' id']);<
token
token means "token". It is a way to verify the user's identity. The simplest token is composed of uid (user's unique identity), time (current time's timestamp) and sign (signature, which is compressed into a certain long hexadecimal string by the first few bits of the token + salt with hash algorithm to prevent malicious third parties from splicing the token request server). You can also put invariable parameters into the token to avoid the difference between cookie and session in multiple database searches.
1. Cookie data is stored in the client's browser and session data is placed on the server
2. Cookies are not very secure, so others can analyze the local cookies and cheat them
considering security, session should be used
3. Session will be saved on the server for a certain period of time. When the number of visits increases, it will occupy the performance of your server.
in order to rece the performance of your server, you should use cookie
4. A single cookie can't save more than 4K of data. Many browsers limit a site to save up to 20 cookies
5. So I suggest that:
save important information such as login information as session
if you need to keep other information, you can put it in cookie
the difference between token and session
session and OAuth token are not contradictory. As an identity authentication token, the security is better than session, because each request has a signature, which can also prevent listening and replay attacks, The session must rely on the link layer to ensure the communication security. As mentioned above, if you need to implement stateful session, you can still add session to save some state on the server side
app usually uses restful API to deal with server. Rest is stateless, that is, the app does not need to use cookie to save session like browser, so it is enough to use session token to mark itself, and session / state is handled by the logic of API server. If your back end is not the rest API of status, you may need to save session in the app. You can embed WebKit in the app and use a hidden browser to manage cookie session.
session is an HTTP storage mechanism, which aims to provide a persistence mechanism for stateless http. Session authentication simply stores the user information in session. Because of the unpredictability of SID, it is considered safe for the time being. This is a means of authentication. Token, if it refers to OAuth token or similar mechanism, provides authentication and authorization. Authentication is for users and authorization is for apps. Its purpose is to give an app the right to access a user's information. The token here is unique. It can't be transferred to other apps or other users. Turn around and say session. Session only provides a simple authentication, that is, if you have this SID, you will be considered to have all the rights of this user. It needs to be kept strictly confidential. This data should only be stored in the website, and should not be shared with other websites or third-party apps. So simply put, if your user data may need to be shared with a third party, or allow a third party to call the API interface, use token. If it's always just your own website and app, it doesn't matter what you use
a token is a token. For example, when you authorize (log in) a program, it is a basis to judge whether you have authorized the software; A cookie is a TXT file written on the client, which includes your login information and so on. In this way, the next time you log in to a website, you will automatically call the cookie and log in the user name automatically; Session is similar to cookie, except that session is a file written on the server, and it also needs to be written on the client, but the file contains your browser number; The token state is stored in the client.
