1. Radar coin and Fuyuan coin have nothing to do, radar coin transaction is very simple, private letter can teach oh

2. First of all, the report quoted in the question is very wrong: bitcoin's original intention is not to break away from government regulation through anonymous payment, but to break away from government control and avoid inflation deliberately created by the irresponsible central government, which will cause great harm to the society. On the one hand, the German government recognizes that bitcoin trading can avoid tax losses. On the other hand, I guess the German people are happy to see bitcoin. From the German government's strong support for the euro, we can see that the German government is very inclined to strictly control the currency issuance: the control of the euro needs to be decided by the European Central Bank, rather than the countries in the euro area themselves. Bitcoin can be said to be the ultimate version of the euro. It is issued by various nodes, not by a central agency. In the European debt crisis, the control effect of the euro is obvious, and the Greek government must vigorously save public expenditure to avoid greater economic turmoil.

5. Without a stable server, there will be no strong ranking, and just because of this: the stability of the server is a prerequisite for all conditions! But it is precisely because of this condition that many websites are in trouble - there are always some people who frequently attack others' websites in a clear way, so as to set off the excellence of their own websites! Headache, headache, website is attacked frequently how should do after all

one: bandwidth size and IIS connection number

let's take a standard enterprise website as an example: generally, 1MB bandwidth and IIS limit of 100 are OK. After all, the whole website page is not complex, and there are not many people visiting it every day. However, once the website is attacked by intentional people, it will immediately fall into "no response state". It's not that the server can't handle it, but that your website "configuration can't keep up". Others just need to refresh your website page or download some large files frequently

don't choose those operators who are too "strict" for the sake of being cheap. The website is usually very smooth, but it can't stand any wind and rain! Of course, there are also some IDC promises not to do any restrictions, but it is not necessarily a wise choice: do not do any restrictions, if there is a website that seriously occupies server resources, then your site will also be involved

currently, the A5 webmaster network recommends Alibaba cloud and Western Digital, which are relatively good. If you don't know what model to choose, it is recommended to contact customer service for consultation. OK ~ advertising for them, it's really free! But it's sharing<

2: hide the real IP address

Why do many large websites do CDN acceleration? Is it really to make users visit faster? In fact, this speed is basically invisible. But its main purpose is: to resist attacks, to rece the independent impact by balancing the load, but the price is often high, not small and medium-sized websites can choose

however, in recent two years, popular services such as 360 website guard and network cloud acceleration have realized this function in disguised form through DNS. At present, they are providing services for free, so that more websites can enjoy this convenience! However, no matter how good DNS is, it is DNS after all. The basic hardware must be closed. Don't do it with "iron cock" thinking

Three: the choice of website programs

some programs are naturally attacked by people, such as "dream weaving" system, which has many loopholes. I don't know how many people will scan it every day. Website construction, it is recommended to choose some more mature website program to do, try not to use some "partial door" program, or temporarily developed but lost maintenance program

for the current mainstream programs, we recommend Empire CMS, discuz, phpcms. Of course, some are more systematic, such as "Knight CMS" recommended by talent.com. We can't list all the different categories of systems here: try to choose some well-known systems that have been developed for many years and have been updated all the time! Don't look for any cracked version, the sky really won't drop pie

Four: server permission settings

for virtual host users, generally do not have to worry about these, but for some VPS or independent operation host users need to do these, including port settings, firewall settings, and upload permission settings, all need to pay special attention

if these programs are to be executed, set the permissions to "pure script", do not set "write" and "script resource access", let alone "pure script and executable program". Otherwise, such as exe type of executable program, at the same time have write permission, then it is very easy to be uploaded Trojan

for IIS configuration, if you are not very good at IIS configuration, and the website is often uploaded and tampered with, it is recommended to apply for a special person to configure it, which will be better

Five: websites should use independent IP

excellent websites will use independent IP instead of sharing IP. The more websites with the same IP, the greater the potential risk! Independent IP website relatively speaking, the overall site type is also better, not many people take independent IP to do garbage station every day, right? Therefore, to a large extent, the problem of "the same IP" being attacked is avoided

as for the choice of independent IP, we suggest that the choice of Telecom IP will be more appropriate. A5 marketing reminds the majority of enterprises: it is not recommended to choose those multi line servers, just choose one line Telecom IP, for example, for the Telecom IP of Western Digital and wanwang, even for the access of China Unicom and mobile users, there will be no delay basically!

6. Modify hosts and write down all the websites you want to ban
hosts in:
in Windows 2000 / XP / Vista / seven system, it is located in systemroot & # 92; System32\ Drivers\ Etc

the following is to prohibit the software of adobe from accessing the network
use Notepad to edit "C: &" 92; Windows\ System32\ Drivers\ etc\” The hosts file in the directory, At the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end: < br /
127.0.0.0.0.0.0.0.1-activate.adobe.adobe.com < br /

after editing, it cannot be saved directly. Can be saved as hosts.txt file to the desktop, and then modify the file name, remove the txt. Then the hosts back and cover it

3D Max is prohibited. Just add the URL you want to ban below.

7. 1. Cleaning and filtering of abnormal traffic:
cleaning and filtering of abnormal traffic through DDoS firewall, top technologies such as rule filtering of data packet, fingerprint detection filtering of data stream, and customized filtering of data packet content can accurately judge whether external access traffic is normal, and further prohibit filtering of abnormal traffic
2. Distributed cluster defense:
this is the most effective way for the network security community to defend against large-scale DDoS attacks. The characteristic of distributed cluster defense is that each node server is configured with multiple IP addresses, and each node can withstand DDoS attacks of no less than 10g. If one node is attacked and cannot provide services, the system will automatically switch to another node according to the priority setting, and return all the attacker's packets to the sending point, making the attack source paralyzed, From the perspective of more in-depth security protection to influence the safety implementation decision of enterprises
good soft defense can achieve the above functions at the same time, such as professional attack defense of ruisu cloud, block chain architecture encryption, seamless integration of lines, hidden source IP, large flow cleaning, unlimited anti DDoS, 100% anti CC, and trial support!

According to the big data talent report, there are only 460000 big data talents in China. In the field of artificial intelligence alone, there are about 150000 employees in India, 850000 in the United States and only 50000 in China. With the continuous development of science and technology, the gap of big data talents in China will increase to 1.5 million in just 3-5 years

According to the Research Report on employment and talents in the digital economy published by BCG, the scale of China's overall digital economy will reach about 16 trillion US dollars in 2035, and the total employment capacity will reach 415 million US dollars

big data has three major employment directions:

Big Data System R & D talents, big data application development talents and big data analysis talents

from the current development, big data will be the most promising career. The core of any system and company is data. The soaring data will give birth to a series of new technologies and instries

at present, there are only 460000 big data talents in China, and the gap of big data talents will be as high as 1.5 million in the next 3-5 years. More and more people join in big data training. At present, the two main trends of big data practitioners are as follows:

1. The salary of employees in the field of big data will continue to grow

2. Big data talents are in short supply
