Injuries pile up ahead of Barca's key European clash******

MADRID, Oct. 31 (Xinhua) -- FC Barcelona's injury list has grown even longer ahead of Tuesday night's key Champions League visit to play Dynamo Kiev with striker Kun Aguero and central defender Gerard Pique both looking likely to miss out.。

With just three points from a possible nine in Europe, Barca has to win in midweek, but stand-in coach Sergi saw his injury list extend on Saturday, with Aguero the most worrying case after the Argentinean striker had to be substituted in the 41st minute of Saturday's 1-1 draw at home to Alaves.。

Aguero complained of feeling dizzy and went to the ground holding his chest. Although he was later able to walk off the pitch in the Camp Nou, he was taken to hospital, where he spent the night after undergoing a series of cardiological tests.。

Meanwhile Pique was forced to limp out of the game and replaced by Clement Lenglet in the second half, with the club informing he has "pulled the soleus muscle in his right calf and will need tests to determine the full extent of the injury."

There is also a doubt over impressive young midfielder Nico Gonzalez, who also looked to be struggling in the closing minutes of the game and could be seen asking to be replaced, although it is not certain at present whether he was asking for a change or merely exhausted.。

Barcelona needs to win in Kiev to have a chance of qualifying for the knockout stages of the Champions League and as well as Aguero and Pique, they will be without central defender Ronald Araujo, midfielders Frenkie de Jong, Sergi Roberto and Pedri.。

Forwards Ousmane Dembele and Martin Braithwaite are also unavailable, meaning Sergi will have to rely on B-team players to make up the numbers in what is arguably Barca's most important game of the season. Enditem。

Twitter co******


In this file photo taken on June 4, 2021, Jack Dorsey, CEO of Twitter and co-founder & CEO of Square, attends the cryptocurrency conference Bitcoin 2021 Convention at the Mana Convention Center in Miami, Florida.。

Twitter co-founder and CEO Jack Dorsey announced on Monday he was leaving the company, after steering the social network during the tumult of Donald Trump's presidency and surviving an activist investor's ouster bid in 2020.。

Dorsey, who is also chief executive of payments company Square, was confronted during his tenure by thorny freedom of speech questions, challenges to making the platform profitable and criticism he had spread himself too thin.。

With his recognizable look of a shaved head, long beard and unconventional style, Dorsey for years embodied Twitter.。

"I want you all to know that this was my decision and I own it. It was a tough one for me, of course," he wrote in an e-mail to Twitter staff announcing his resignation as CEO, which was effective immediately.。

"There aren't many companies that get to this level. And there aren't many founders that choose their company over their own ego," he added.。

The company said Twitter's Chief Technology Officer Parag Agrawal has replaced Dorsey in the top post, with Dorsey saying he would remain a member of the board until around May to help with the transition.。

"And after that... I'll leave the board," Dorsey wrote. "Why not stay or become chair? I believe it's really important to allow Parag the space he needs to lead."

Nasdaq briefly suspended trading of Twitter on Monday, citing "news pending," and after some volatility, the price was down over 2.5 percent for the day.。

Trump era。

Like many Silicon Valley celebrities, from Mark Zuckerberg and Steve Jobs to Bill Gates or Michael Dell, Dorsey dropped out of college, never graduating from either of the universities he attended, one in his native Missouri and the other in New York.。

Dorsey is credited with coming up with the idea for Twitter when eventual co-founder Evan Williams gave workers at blogging startup Odeo two weeks to work on new projects as a way to break up the daily routine.。

He ran Twitter from 2007 to 2008 and returned later as CEO after Dick Costolo resigned in June 2015.。

With Dorsey at the helm, Twitter reported its first profitable quarter for the last three months of 2017, and then two full years in the green, before slipping back into the red in 2020.。

Twitter in March 2020 made a deal with key investors to end an effort to oust the chief, creating a new committee on the board of directors to keep tabs on company leadership.。

Dorsey came under pressure in 2020 from Elliott Management amid concerns he had spread himself too thin by running both Twitter and Square.。

During Trump's presidency, which ended in January this year, Twitter was widely seen as the medium used to broadcast America's deepening political and cultural rifts.。

Dorsey took the controversial decision to permanently ban Trump from the platform, where the former president had amassed 88.7 million followers.。

Dorsey made the decision days after Trump whipped up a mob of supporters who stormed the US Capitol, where they tried to prevent Joe Biden being confirmed winner of the 2020 election.。

New CEO。

Twitter's incoming CEO Agrawal joined the company in 2011 and has served as chief technology officer since October 2017, where he was responsible for the network's technical strategy.。

Dorsey cited Agrawal's understanding of the company as key to his decision to step down.。

"There's a lot of talk about the importance of a company being 'founder led.' Ultimately, I believe that's severely limiting and a single point of failure," Dorsey wrote to Twitter staff.。

Agrawal holds a PhD in computer science from Stanford University and a bachelor's degree in computer science and engineering from the Indian Institute of Technology in Bombay.。

"We recently updated our strategy to hit ambitious goals, and I believe that strategy to be bold and right," he wrote in his own message to staff.。

  两套方案相同的地方在于电源和SSD与机箱,电源使用的是酷冷至尊的GX550,DC-DC还有全日系电容、五年质保、并且550W的功率也为后期升级留下一定冗余。SSD为西数SN550 500G版本原厂颗粒,质量相对而言较有保障。




  搭配的微星B450 MORTAP MAX主板,支持原生3代锐龙,兼容性较好,并且做工优秀,相比较于其他主板,此款主板定位中高端,整体均衡,并且支持双M.2接口,扩展性较好。配备RTX2060显卡对于现在游戏而言,基本上都可以满足流畅的1080P高特效。此外其他方面方案1已经提及,故略过。至于散热器方面,可以选用自带或者另外更换。

  将RTX2060替换为GTX1660 SUPER在游戏性能上GTX1660 SUPER相比较于RTX2060在非光追游戏方面差距也就15%-20%相比较于GTX1660Ti差距在10%左右,所以在这方面GTX1660 SUPER也可以很好地玩游戏,也可以适应一定的生产力环境。






  来到7K以上价位段,就有了更多更高端的选择,在这个价位段CPU可以从R5-3600到R9-3900或i5-10400到i9-10900K。配备显卡可以从RTX2060到RTX2080Ti,但是由于现阶段30系列显卡发布在即,使用并不建议选配过高端显卡。主板方面AMD可以选配X470/B550/X570, INTEL方案可以选择B460/Z490。储存方面也可以选用1TSSD,电源选配650W以上。



  主板方面选择的都是两家的顶级主板X570与Z490都是目前两家最新的主板,支持一系列新特性。显卡选配了RTX 2070 SUPER这一系列的CPU和显卡加持下,游戏不在话下,并且也有挺不错的生产力。









China Focus: Special coal transportation trains expected to ease power crunch******

CHONGQING/TAIYUAN, Nov. 14 (Xinhua) -- An average of 20 freight trains fully loaded with coal arrive in southwest China's Chongqing Municipality every day from Shaanxi and Shanxi provinces, major coal production bases, as well as Xinjiang Uygur Autonomous Region to help fuel coal-fired power plants in the megacity.。

Due to a slew of overlapping factors such as rapid economic recovery, swift foreign trade and rising coal price, west China's economic hub of Chongqing has faced power supply pressure since the third quarter.。

From January to October, Chongqing's total electricity consumption increased by 14.9 percent year on year. In October alone, coal-fired power consumption soared by more than 300 percent year on year.。

According to the Chongqing economic and information committee, Chongqing's thermal power accounts for over 60 percent of its installed power capacity, while all coal needs to be diverted from outside the city.。

Since the beginning of this year, Shaanxi Province has supplied 8.8 million tonnes of coal to Chongqing, an increase of 84 percent year on year. Chongqing has also stepped up the purchase of coal from Shanxi and Xinjiang, which are expected to deliver a total of 4 million tonnes of coal to Chongqing this winter and next spring. The supplemental purchase can guarantee Chongqing's power supply.。

Coal trains are also gathering at Hudong Station in China's first coal transportation railway line linking the coal production city of Datong in Shanxi with Qinhuangdao Port in Hebei Province, from where coal can be transferred to the country's southern and eastern regions for power supply and heating.。

Datong-Qinhuangdao Railway, deemed China's energy transport artery, is an electrified railway designed exclusively for transporting coal from the provinces of Shanxi and Shaanxi and the Inner Mongolia Autonomous Region to the energy ports of Qinhuangdao and Caofeidian.。

China Railway Taiyuan Group Co., Ltd. has increased its daily train trips to 94 from 85, with the departure interval shortened to every 13 minutes on the railway, said Ren Xin, deputy director with the company's dispatching office, adding that the trains carry 1.3 million tonnes of coal per day.。

The coal output in Shanxi is expected to exceed 1.2 billion tonnes this year and the power transmission from the province will exceed 9 million kilowatts in December. The output of coal-bed methane will reach 4.2 billion cubic meters this winter and next spring, forecast local authorities.。

In the first seven days of November, Shanxi's average daily coal output reached over 3.5 million tonnes, an increase of 170,000 tonnes compared with that in October, showed data from the energy bureau of Shanxi.。

As of Nov. 9, Shanxi has supplied 15.19 million tonnes of coal to 14 provinces, regions and municipalities including Shanghai, Zhejiang and Jilin. Enditem。
