When will Shuozhou bath center resume work

1. The bath center should set the time to start counting! It will arrive at one o'clock in three hours

2. All right

3. ZhuMou, deputy director of Pinglu branch of Shuozhou Bureau of land and resources (section level), took a bath and had a rest in Shuozhou Tianlun hot spring business club by driving a bus. He was removed from the post of deputy director. At the same time, Gu (worker), the driver of Shuozhou municipal Party school, took a bus to take a bath in Shuozhou Tianlun hot spring business club. It is suggested that the Party School of Shuozhou municipal Party committee should deal with it seriously and report the result to Shuozhou Municipal Commission for Discipline Inspection.

4. The following are the ways to earn green money:
1 To tell you the truth, you don't earn much, and unless you are in urgent need of green money, you don't need to brush your achievements, just accumulate them graally)
2 This can be said to be the most common and practical way. Although you earn very little every time, you will print out advertisements every hour or two with your level, which actually accumulates a lot)
3 Collectibles can be obtained by ship transportation and mining. It's very difficult to do, and it doesn't earn much. It's suggested that you don't care about it for the time being, accumulate it slowly, and get it when it's full)
4 You can see 3-5 orange balloons in your home or other people's home every day. The first one you meet is free of charge. You can issue green notes, gold coins and building materials. The rest need three green notes to issue. If you issue more green notes than you spend, you will make a profit, but you have to have good luck)
5. Sell metal ingots A helicopter mission, when you have a foundry, will brush out, give metal ingot will exchange equivalent experience and green money
6. Air transportation Every time you fill a plane, you have a chance to get gems, building materials, green bills and other items)
7 This depends on the official update. In the last animal relay, you just need to take part in nothing and get ten green bills at the end of the event.)
8. Out of the lucky box The clover collected at ordinary times can be used to open the box, and there is a probability to get small green bills and large green bills, but the probability is not big.)
to sum up, the second way is the most practical way, and the fastest way is one and four, but the first one is more and more difficult to earn, because achievements are more and more difficult to complete
the result of going to TB to buy green money is that you will be blocked, that is, you can't interact with other players and become a stand-alone game
for zoos, there's no need to focus on them, because there's still a shortage of gems for animals, and the building materials are different from those of small towns. After completing some simple achievements about zoos, you can let them go. You can sell simple crops in zoos regularly. If you have energy, you can also do it, However, it is suggested that the town should be built before the zoo< br />

5. So far, there is no subway passing through this station, but there are many buses passing by, such as fan183, fan189, fan25, etc

Single thread you don't block, redis delay problem analysis and response

redis event loop in a thread processing, as a single thread program, it is important to ensure that the event processing delay is short, so that the subsequent tasks in the event loop will not block
when the amount of redis data reaches a certain level (such as 20g), blocking operation has a serious impact on performance
let's summarize the time-consuming scenarios and solutions in redis

the time-consuming commands cause blocking

keys, sort and other commands

keys command is used to find all the keys that conform to the given pattern. The time complexity is O (n), and N is the number of keys in the database. When the number of databases reaches tens of millions, this command will cause the read-write thread to block for several seconds
similar commands include Sunion sort and other operations
What if the operations such as keys and sort must be used in business requirements

solution:


if the official sentinel is used, it will be upgraded, and the overall implementation will be relatively complex; It is necessary to change the IP configuration of the available slaves and remove them from the query nodes, so that the query load of the front end will not fall on the new master; Then, the switch operation of sentinel can be released, and the context needs to be guaranteed

the blocking caused by persistence

the implementation of persistence (AOF / RDB snapshot) has a great impact on the system performance, especially when there are other disk reading and writing operations on the server node (for example, the application service and redis service are deployed on the same node, and the application service records in and out logs in real time); Redis persistence should be avoided on nodes with heavy IO as far as possible

when the subprocess is persistent, the conflict between the subprocess's write and the main process's fsync results in blocking

on the node with AOF persistence enabled, when the subprocess is performing AOF rewriting or RDB persistence, redis query is stuck or even blocked for a long time. At this time, redis cannot provide any read-write operation

cause analysis:
the redis service has set appendfsync everysec, and the main process will call fsync() every second, requiring the kernel to write the data "really" to the storage hardware. However, the main process fsync() / operation is blocked because the server is performing a large number of IO operations, When the AOF fsync policy is set to always or everysec, and a background
saving process (a background save or AOF log background rewriting) is
performing a lot of I / O against the disk, In some Linux configurations
redis may block too long on the fsync() call. Note that there is no fix for
this currently, as even performing fsync in a different thread will block
our synchronous write (2) call.
when performing AOF rewriting, there will be a lot of IO, which will cause fsync block in some Linux configurations

solution:
set no appendfsync on rewrite yes, when the child process performs AOF rewrite, the main process does not call fsync() operation; Note that even if the process does not call fsync (), the system kernel will write the data to the hard disk at an appropriate time according to its own algorithm (the default time of Linux is no more than 30 seconds).
the problem caused by this setting is that in case of failure, the longest time of data loss may be more than 30 seconds instead of 1 second

when the AOF of the subprocess is rewritten, the sync of the system causes the write blocking of the main process

let's sort out the following:
1) cause: there are a lot of IO operations writing (2) but the synchronization operation is not actively called
2) cause a lot of dirty data in the kernel buffer
3) when the system is synchronized, the sync time is too long
4) cause the write blocking of the AOF log of redis (2)
5) causes the next event of single thread redis to be unable to be processed, and the entire redis is blocked (the event processing of redis is carried out in one thread, in which the write (2) of AOF log is the call of synchronous blocking mode, which should be distinguished from the non blocking write (2) of network)

1) causes: This is a problem before redis2.6.12, and AOF rewrite always calls write (2), The system itself triggers sync
another reason: the system IO is busy, for example, other applications are writing disks

solution:
control system sync call time; When there are many data to be synchronized, it will take a long time; Rece the time consuming and control the amount of data synchronized each time; By configuring (VM. Dirty_ background_ Ratio) or by value (VM. Dirty)_ Bytes) to set the call threshold of sync Generally, it is set to 32m synchronization once)
after 2.6.12, when AOF rewrite 32m, fdatasync will be called actively

in addition, when redis finds that the file currently being written is executing fdatasync (2), it does not call write (2), but only exists in the cache, so as not to be blocked. But if it is still like this for more than two seconds, write (2) will be enforced, even if redis is blocked

blocking caused by merging data after completion of AOF rewriting

in the process of bgrewriteoaf, all new write requests will still be written to the old AOF file and put into the AOF buffer at the same time. When the rewrite is completed, the main thread will merge this part of the content into the temporary file before renaming it into a new AOF file, so & quot; will be printed continuously ring the rewrite process; Background AOF buffer size: 80 MB， Background AOF buffer size: 180 MB"， To monitor this part of the log. This merging process is blocked. If a 280MB buffer is generated, redis will block for 2.8 seconds on a 100MB / s traditional hard disk

solution:
set the hard disk large enough to increase the threshold value of AOF rewriting to ensure that rewriting will not be triggered ring peak period; Use crontab to call AOF rewriting command in idle time

7. 1. The master-slave is necessary, but now the proxy of redis is not stable, and the master-slave exception has to be manually switched
2. Persistence. According to the data change frequency and data volume, adjust the persistence parameters, and select RDB or AOF for persistence
3. However, if it is used for caching, it is best to be able to rebuild from the business
4. There is an SSDB in China. Personal test results show that SSDB can achieve about 20% of redis performance, but the cluster is better, and it can be used to replace redis in some projects

Hurun Research Institute released the "2016 Hurun IT rich list" released on the 18 day. Ma Yun and Ma Huateng ranked the top two in the fortune list of IT. The founder of NetEase Ding Lei and Robin Li, the founder of the network, were separated by third, fourth. The 11 people, including Didi, the US group, the US chart and the founder of the perfect world, made their first list. p>

this is the 14th time in a row that Hurun Research Institute has released the top 50 of Hurun it rich list. Different from Hurun 100 rich list, it rich list only calculates entrepreneurs' wealth in IT field. The average wealth and entry threshold of the top 50 IT tycoons have reached the highest level over the years. The average wealth has increased by 13% over last year to 26.9 billion yuan (RMB, the same below); The threshold for listing rose 9% over last year to 8.8 billion yuan. 11 new people were on the list, accounting for 22% of the total number of it. The average age is 49 years old, 4 years younger than the average age of Hurun 100 rich list

according to the list, Ma Yun, 52, and his family became "the richest man in it" for the third time with 195 billion yuan. Ma Huateng, 45, came second with 134 billion yuan, an increase of 30% over last year. Ding Lei, 45, doubled his wealth to 96 billion, surpassing Robin Li in the top three. Robin Li and Madame Ma Dong, the richest 48 year old former IT, maintained fourth, and their wealth increased 18% over last year. p>

in the top 10 of the list, Lei Jun, the 47 year old founder of Xiaomi, dropped 2 places to the fifth, and his wealth was 30% less than that of last year. Zhang Zhidong, 44, another core founder of Tencent, rose three places to sixth, with a 64% increase in wealth. Liu qiangdong, 42, founder of Jingdong, dropped one place to the seventh place from last year. Jia Yueting, 43, founder of LETV, lost 10% of his wealth and ranked eighth. Pan Zhengmin, 49, of Ruisheng technology, rose 12 places to ninth. Jiang nanchun (microblog), 43, founder of focus media, rose 171% in wealth and ranked 19 places in the top 10

Hurun, chairman and chief researcher of Hurun Baifu, said: "these entrepreneurs on the list should be called" super wealth creators ", rather than simply" rich ", so as to reflect their value to China's society and economy. They have created so many new opportunities and jobs."

According to statistics, five "post-80s" are on this year's it rich list, and four of them are self-made“ Wang Tao, 36, is the richest "post-80s" self-made IT tycoon with 24 billion yuan. The other four are Didi's 33 year old Cheng Wei, he Zhitao, 34, Haihong Holdings' 34 year old Kang Qiao and Youzu network's 35 year old Lin Qi

among the 11 new people on the list, 10 have a wealth of more than 10 billion, two more than last year. Shanghai giant Shi Yuzhu, 54, is the richest newcomer, ranking 11th on the it list with 30 billion yuan. Others include Huawei Ren Zhengfei, Didi Chengwei, meituan Wang Xing, Meitu Cai Wensheng, and perfect world Chi Yufeng
