Hello Ethereum

1. I have bought many versions of interstellar miner before, but on the whole, the interstellar infinite K1 miner is OK. Compared with other features, the interstellar infinite miner has the advantages of low energy consumption, high configuration, advanced operating system, low noise and special mining methods. Low energy consumption: a bitcoin miner, the ant S9 miner, is 1700W an hour, while the interstellar infinite miner is 30W an hour. High configuration: 4G standard memory, Intel quad core high-speed CPU, built-in customized version of Intel motherboard, so that the running speed of mining machine is impeccable. At the beginning, it comes with 2000 + enterprise 8t hard disk, which wins at the starting line and takes the lead in mining. Advanced operating system: K1 (interstellar unlimited miner model) uses Linux system, which is stable, safe and powerful. Compared with windows, K1 is more suitable for development environment or actual proction environment. K1 has hot plug function that some miners don't have. The hot plug function facilitates the replacement of the hard disk, greatly improves the work efficiency, reces the damage probability of the mining equipment, increases the effective mining time of the mining machine, and improves the unit time yield of the mining machine. Low noise: K1 mining machine in order to meet the needs of customers at home mining, equipped with ultra quiet fan. Even if you dig at home, you won't be bothered by the noise of the miner. Mining mode: Mining depends on the transmission speed of uplink broadband traffic. Bitcoin and Ethereum both rely on CPU to mine. Both are chips, but the processing proceres are different. The interstellar infinite miner mines through the transmission speed of broadband traffic. I hope the great God will adopt it

The best in the IPFs field should be Star Alliance, and the price is very close to the people. At present, there are too many domestic companies selling IPFs mining machines, 300-500 or more. At present, there are only a few companies in the first tier. StarCraft is one of them

Pfsunion Star Alliance is headquartered in Mordor Shanghai. The team is composed of backbone members from Internet giants such as Microsoft, AMD, Ali, Tencent, sap, Huawei, Shanda and Yingyeda. It has a mature and complete instrial supply chain, and has many branches and partners at home and abroad

since its establishment, Star Alliance has focused on the research and development of blockchain technology with the support of technology, focusing on building a global IPFs ecosystem around IPFs filecoin, providing mining machinery, mining, hosting, data, application, knowledge, and marketing services

Compared with other companies, Star Alliance has four advantages:

1, low price and high cost performance

2

3. The computing power growth rate of Star Alliance is the first

4. Long term strategic planning, with five development strategies of mining machinery, mining pool, mining field, application and chip

extended materials:

to evaluate the good and bad of a service provider, we should look at these aspects:

1. Whether the founder team of the company is born in R & D or marketing. If they are all R & D teams, and each of them has more than 10 years of experience, both blockchain development experience and server operation and maintenance experience, the overall team is more than 50 people

2. With the coming of the main network, the layout has begun. First of all, it is necessary to choose a technology-based mining machinery hosting company to cooperate, because once the main network is online, the strength of each technical team will decide whether it can grab more orders faster and dig more money than others. At present, the hard disk is almost Seagate, regardless of cloud computing power or physical hosting. In general, the technology of IPFs is revolutionary

3. Show interface X / X can view the detailed information of the specified port, including MAC address, bandwidth, QoS, IP address, encapsulation, etc. There are several cases of protocol down: 1. IP address conflict, subnet mask setting error 2. DCE clock is not set 3. Encapsulation of FR and PPP is not set 4. Update clock of hello and dead, routers at both ends are different 5. Routing protocol setting error

4. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm for building trust and gaining rights and interests between different nodes in the blockchain system. IAC's latest new etheric clown game, each clown has 54 pairs of gene codes, which is also divided into male and female. With the occasional gene mutation of paternal and maternal lines, clowns can obtain some extremely scarce shapes. It is a digital collection, which is the most typical and important feature of every clown. Every clown can have children and work to earn money, which will graally appreciate over time. Based on the blockchain, it can never be changed: all the behaviors of clowns will be recorded in Ethereum, and the host can clearly query all the above data information of clowns through the verification of the third-party platform. This game really makes players get a more comfortable experience, and at the same time, it combines with blockchain technology to ensure the interests of players.

(ether clown) to introce you to a fun game Hello, Hello everyone, I'm ether clown, IAC's new blockchain adoption game. The English name is cryptoclown, which is a digital blockchain game with collection value developed by Ethereum blockchain. My appearance is unique. I can work to earn rice and breed the next generation of clowns;, The key is that I earn more and eat less. Another typical feature is digital collection. There are a lot of amazing features, want to know, download, let me play together# Etheric clown

6. Blockchain game ether clown is new online, will make money pet understand< Hello, human beings
who are we
we are etheric clowns, whose full name is cryptotown. We are the protagonists of the blockchain nurturance game ~
our slogan is: you can buy cute, you can play cute, you can do work
most importantly, we will make money ~

cryptoclones is a digital blockchain game with collection value based on Ethereum blockchain. Using ether money to adopt clowns can be resold, and they can also be used to breed a new generation of clowns with strange shapes. They can also be cultivated to work and earn money, which makes the digital collection of clowns more sustainable and playable

in other words, the true identity of our clowns is digital collection, which is a non-standard digital currency, that is, the value of each unit is not equal
just as you human beings have different heights and weights, we clowns also have different monetary values. With your careful care, we will grow up, that is, we will have higher and higher monetary values
at the same time, when we grow big enough (growth value reaches 100), you can send us to work to make money
we are all good clowns. It's very safe, because we are based on blockchain and can never be changed: all the above behaviors will be recorded in Ethereum. You can clearly query all the above data information through the verification of a third-party platform. Our smart contract part of the code, are open source, you can view

What's the matter? Are you excited? Action is better than heart. Take us home quickly!

7. Although it is a new company, its parent company, nebula ocean, is still very powerful in Singapore. It set up interstellar linkage and then deployed IPFs & filecoin together with hellofil, the third largest company in the world. At that time, it still had a certain influence

Nebula ocean is an investment institution established by Singapore consortia in 2013 to focus on blockchain projects. From 2014 to 2018, it has successively participated in the ICO of Ethereum, the Dao, lisk, auger, ant stocks, quantum chain, IPFs and other star projects.

If you don't understand, you can ask me directly

9. You should know that tcpmp is used to view the packets on the network, or ask 802.1d config, which should be generated when the switch runs STP
in addition, it's better to add the parameter - n with tcpmp, otherwise domain name inversion will be carried out, which is very slow

10. #include < stdlib.h> int system(const char *string); Example: in the ~ / myprogram / directory, there is a shell script test.sh with the content #! Bin / bash#test.shecho $home create a new C file Systemtest. C in this directory, the content is: #include & lt; stdlib.h> main(){
system("~/ myprogram/test.sh");} The results are as follows: xiakeyou@ubuntu :~/myprogram$ gcc systemtest.c -o
systemtestxiakeyou@ubuntu :~/myprogram$ ./systemtest/home/d/e/ xiakeyouxiakeyou@ubuntu ~/myprogram$2) Popen (char *command, char *type) execution process: Popen () calls fork () to generate the child process, and then invokes /bin/sh
-c from the sub process to execute the instruction of parameter command. The parameter
type can use "R" for reading and "W" for writing. According to this type value, popen() will establish a pipeline to the standard output device or standard input device of the child process, and then return a file
pointer. Then the process can use this file pointer to read the output device of the child process or write to the standard input device of the child process. In addition, all functions that use the file pointer (file *) operation can also be used
except fclose(). Return value: if successful, the file pointer will be returned; otherwise, null will be returned. The error reason is stored in errno
note: when writing a program with suid / sgid permission, please try to avoid using Popen (), which inherits environment variables and may cause system security problems through environment variables. For example, the content of C program popentest. C is as follows: # include & lt; stdio.h> main(){FILE * fp; charbuffer[80]; fp=popen(“~/myprogram/test.sh”,”r”); fgets(buffer,sizeof(buffer),fp); printf(“%s”,buffer); pclose(fp);} The results are as follows: xiakeyou@ubuntu :~/myprogram$ vim popentest. cxiakeyou@ubuntu :~/myprogram$ gcc popentest.c -o popentestxiakeyou@ubuntu :~/myprogram$ ./popentest/home/d/e/ xiakeyouxiakeyou@ubuntu : ~ / myprogram $
it's just that my ability may be a little limited and I don't understand it very well. It's a script to use system () directly, but the return value is a mess. I tried many times, but I didn't find any rules. I can't help but look at the above blog post and get some inspiration, which can be realized as follows: first, use echo & gt; to return the script value; Xxxxx output to a local file, when you need this return value is, but through the C language file operation function to read directly from the file, later on, this should be the Popen implementation method! There are three ways for C program to call shell script: system (), Poppen (), exec series function system ()
you don't need to generate a process by yourself, it has been encapsulated, you need to fork your own process to directly add your own command exec, and then the exec's own command Poppen () can also execute your command, which is less than the system cost. 1) system (shell command or shell script path); System() will call fork() to generate a subprocess, and the subprocess will call / bin / SH-C string to perform the command represented by the
parameter string string. After the command is performed, the original calling process will be returned immediately. The sigchld
signal will be temporarily suspended while the SIGINT and sigquit signals will be ignored ring the call to system()
return value: if system() fails to call / bin / sh, 127 will be returned, and - 1 will be returned for other failure reasons. If the parameter string is null, a non-zero value is returned
if the system() call is successful, the return value after the
shell command is fulfilled will be returned. However, this return value may also be the 127 returned when the system() call / bin / sh fails. Therefore, it is better to reflect on errno
to confirm the successful fulfillment. System command is widely used because of its simple and efficient function. Here is an example: there is a shell script test.sh in ~ / test / directory, and the content is #! Bin / bash#test.shecho Hello create a new C file system in the same layer directory_ Test. C, the content is: # include & lt; stdlib.h> int main(){system("~/ test/test.sh");} The effect of performance is as follows:[ root@localhost test]$gcc system_ test.c -o system_ test[ root@localhost test]$./system_ testhello[ root@localhost Test]$2) Popen (char *command, char *type) Popen () calls fork () to generate the child process, and then invokes /bin/sh -c from the sub process to perform the instruction of
parameter /bin/sh. The parameter type can be applied with "R" for read and "W" for write. Following this type value, popen() creates a
pipeline to the standard output device or standard input device of the child process, and then returns a file pointer. Then the process can use this file pointer to read the output device of the sub process
or write it to the standard input device of the sub process. In addition,
can be applied to all functions that apply file pointer (file *), except fclose(). Return value: if successful, the file pointer will be returned; otherwise, null will be returned; the error
reason is stored in errno. Note: when you write a program with suid / sgid permission, please try to avoid using Popen (), which will inherit environment variables, which may cause system security problems. For example, the content of C program popentest. C is as follows: # include & lt; stdio.h> main{FILE * fp; charbuffer[80]; fp=popen(“~/myprogram/test.sh”,”r”); fgets(buffer,sizeof(buffer),fp); printf(“%s”,buffer); pclose(fp);} The effect of performance is as follows:[ root@localhost test]$ vim popentest.c[ root@localhost test]$ gcc popentest.c -o popentest[ root@localhost test]$ ./popentest/root/test[ root@localhost test]$
