US media: Ballmer is tired of failure, and the new season will be his last bottom line.

Earlier on August 4th, Beijing time, the US media once again followed up and reported some internal news about the Clippers. Ballmer, the owner of the Clippers, was tired of failure. The 22-23 season will be an important node for him to assess the players and the future development of the team, and it is also his final bottom line. It is completely understandable that Ballmer chose to renew his contract cautiously in advance at this time. After he took over the Clippers, he showed his ambition to the league and fans. He was often seen in the home game. He cheered for the team crazily. Ballmer was also not idle in some important away games. He followed the team to the away game, and he spent a lot of money. His investment in the team has always been among the best in the league. In order to have an independent team culture and mark him, he invested heavily in building a new arena. Ballmer’s vision for team management is also very vicious. He even invited the LOGO man. Looking at the transactions and contracts made by the old West in the Clippers in recent years, it is basically correct. However, the Clippers’ double stars have fallen in front of injuries again and again in recent years, and the team has fallen in the playoffs again and again. As the owner of the team, Ballmer has done everything he can, and it is right to be cautious now. The next season will be a huge test for the Clippers, as will George, 33, and Leonard, 32. Age and past injury history will put the future contract renewal in doubt unless they can show Ballmer and fans different performances, higher attendance and good competitive state in the new season.

Real-time production data is accessed in real time and reliably transmitted to the company’s database cluster. The data access amount is about 110TB/ day, and the historical data is 40000TB.

Logical architecture diagram of data migration

L Data lake operations are divided into two categories: inelastic and elastic. For inelastic operations, operations are performed in the local data lake. For operations that consume large resources and need elastic calculation, collaborative calculation is adopted with the enterprise cloud, and data is not saved in the enterprise cloud data lake. After the operation calculation is completed, the process and result data are sent back to the local data lake for storage. Interface service supports publish-subscribe mode, cross-data lake and cross-system call, HDFS, Hive, HBase and other systems.

A) interface type

Bulk data encapsulation

A large number of data are extracted according to certain conditions and packaged into data resources. Batch data packaging must be carried out through the system, not manually.

Data request interface encapsulation

The data is encapsulated as an access interface by restful interface, so that the accessor can access the data through remote call.

B) interface security

configuration management

Configure the content of shared data and sharing interface rules, including basic data configuration, sharing service configuration, sharing rights and sharing configuration distribution.

A) basic data configuration

[Appreciation of AI Painting Works-Antique] The first attempt to use AI painting, the effect is shocking

AI painting, that is, artificial intelligence painting, has broken through the limits of human beings, thus allowing painting analysis to enter a broader field of vision with humanistic spirit as the starting point and the foothold. Through artificial intelligence, a new field of painting art is opened. Artificial intelligence painting is usually mysterious, gorgeous, deep, complex and has a strong sense of the times, reflecting extraordinary imagination. Symbolizes the future development direction of painting.

As we all know, the level of AI has now reached a terrible level. AI painting is very popular recently, and the author himself has tried it, and the result is really surprising.

After thinking, I chose the tone of ancient style and tried to do the first AI painting.

The final output results are really surprising, and individual photos have reached the point where it is difficult to distinguish between true and false.

(As I am a beginner, I am not proficient in the use of AI painting software, and the computer equipment used is relatively old, so I only output the above four pictures.)

What picture should AI draw next time? You are welcome to leave comments, and I will try my best to meet your requirements.

The national football team plays today! Hit the Asian Cup semi-finals, the two favourites to win the championship are out, which is a lesson for Japan and South Korea.

The quarter-finals of the U20 Asian Cup are in full swing! China men’s soccer team is about to face the powerful Korean team in the quarter-finals! In the two Asian Cup knockout matches completed before this, the two favourites to win the championship were all out!

Host Uzbekistan vs Australia! Uzbekistan successfully drew Australia and dragged the game into a cruel penalty shootout. In the final penalty shootout, Uzbekistan advanced to the top four of the U20 Asian Cup with a total score of 6-5. Another game, the same is to defeat the strong with the weak! Iraq beat Iran 1-0 to advance to the top four! Two other places will be promoted soon. China and South Korea, Japan and Jordan will compete for the last two semi-finals of the Asian Cup!

China U20 men’s soccer team returned to the quarterfinals of the Asian Cup after 9 years! In the death group, China suffered a severe reversal when it led Japan 1-0 in the opening match, and got a good start 1-2. After that, the national football team broke out in desperation, defeated Saudi Arabia 2-0 in the qualifying battle, and drew Kyrgyzstan 1-1 in the final qualifying key battle to successfully qualify for the second place in the group! In the face of South Korea, the China team has no retreat, and it is expected that the national youth players will show their fighting spirit and fighting spirit and do every detail as they did against Saudi Arabia.

Against the powerful Korean team, the China men’s soccer team is not without opportunities! This year’s China U20 national football team clearly identified its position, adhered to the defensive counterattack and achieved great success, which was also able to miraculously qualify in the death group! Now, if we continue to stick to the defensive counterattack strategy, the miracle is likely to be continued! After three group matches, China U20 national football team’s ability to fight is constantly improving, and the goalkeeper’s brave play and the defense of China men’s football team are reassuring!

The future of China Men’s Football Team is in Xinjiang! Up to 7 players in the current U20 National Youth Team are from Xinjiang! Those who can’t kill us will only make us stronger! Every time the South Korean team fails to attack, it is an accumulation of opportunities for the national youth soldiers! With a good defense, China only needs a defensive counterattack to kill South Korea and advance to the Asian Cup semi-finals!

If miracles have color, it must be red! Looking forward to our national youth fighters, in the life-and-death war with South Korea, there will be no regrets! China’s men’s soccer team won the U20 Asian Cup, dating back to 1985, and the men’s soccer team in South Korea and China looked forward to a miracle.
