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******

AFP。

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.。

POP最惠买:2020开学季的DIY攒机安利******

  随着开学的脚步越发临近,对于很多大学新生来说配备一台电脑在大学期间使用就成为了一个比较纠结的选择。而在电脑的选择中,除了笔记本,那还可以选择攒一台台式机带到大学的生活中。那么今天这篇《POP最惠买:开学季的DIY攒机安利》就为各位带来一些攒机配置。

  本次攒机配置追求稳定及相对较均衡配置,追求较小性能瓶颈,同时配置方案的选择也留有一定的升级空间。各位可以进行参考。

  首先,我们需要考虑一下宿舍环境,宿舍是否限电,是否限制功率?宿舍能放下多大的机箱?请务必在装机前确认宿舍情况,避免因为功率或者机箱大小导致用不上的尴尬局面。

  其次明确你的使用场景,是玩大型3A,渲染工程什么的,或者只是如LOL之类的较轻娱乐,又或者只是编辑Word之类的简单工作。

  那让我们来进入正题:

  2-3K价位段的选择(办公及网游/轻度3A)

  此价位段基本为轻办公或LOL之类的网游配置,大概参考如下:

  R5-3400G加A320M主板,或i3-9100F加H310M或B365/360M主板加GTX1650并配置8G内存条,加256G SSD与450W左右电源,机箱配置价格大概150元左右。

  详细可参考配置如下

  这两套配置就可以较好的进行办公也可以游玩LOL或者一些网游及此前3A游戏。要注意的是,此为M-ATX配置,如果需要便携需要重新考虑机箱与主板配置。

  点评一下R5-3400G为四核八线程、频率为3.7GHz-4.2GHz,并且配备Vega Graphics 显卡,对于办公或者大部分网游都可以流畅游玩。

  而i3-9100F为四核四线程、频率为3.6GHz-4.2GHz,因为阉割核显,使用需要另外加配显卡,此次选配为一张千元机的入门卡,可以满足现阶段大部分网游的配置,并且对部分3A也能以最低限度进行游玩。

  4K-5.5K的选择(3A流畅/一定生产力)

  此价位段可以选择较好的配置,可以对目前3A有一个流畅体验,也可以进行一定的生产力操作。

  可以选择R5-3500X到R5-3600XT或者i5-9100F到i5-10400的水平段CPU,主板配备为AMD方案B450M系列主板,INTEL方案B360M或B460M主板。显卡可选择从GTX1650Ti到GTX1660Ti。并且也可以选择较好的机箱与电源等等。SSD方面的容量也可以进行提升。

  详情可参考配置如下:

  方案1

  这两套方案1为5.5K价位段较均衡选择,分为AMD与INTEL两个方案推荐,在AMD方案1中采用了R5-3600,这款CPU拥有六核十二线程,基础频率3.6GHz、加速频率4.2GHz,支持PCIE4.0技术。

  而搭配的微星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。搭配一张GTX1660Ti已经可以满足大部分3A的1080P中高画质流畅需求,并且由于CPU核心较多,可以较好配合完成诸如建模、渲染等生产力操作,此外因为AMD平台对内存条频率要求较高,故选配3600频率的DDR4内存条。

  而在INTEL方案1中采用了最新的10代酷睿i5-10400F,此款CPU同样为六核十二线程,基础频率2.9GHz、加速频率4.3GHz。

  而搭配主板为技嘉B460M AORUS PRO,此款主板支持英特尔第十代处理器,同样支持双M.2插槽,定位中高端,做工优秀。INTEL方案1同样配备一张GTX1660Ti显卡,此搭配同样较为均衡,可以满足大部分3A的1080P中高画质流畅需求,并且由于CPU核心较多,可以较好配合完成诸如建模、渲染等生产力操作。与AMD方案1不同的是,由于INTEL对高频内存不敏感,使用可以使用2666频率内存足矣。

  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。

  散热器方面,由于这两套方案追求相对均衡,故采用其他散热器替换盒装自带,避免因为散热不足带来瓶颈。

  方案2

  这两套方案2为5K价位段的侧重游戏体验选择。这两套的CPU均没有超线程,均为六核心六线程。AMD方案2选用了R5-3500X,频率3.6-4.1GH。

  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。

  而在INTEL方案2中选用的九代酷睿i5-9400F,频率为2.9-4.1GHz,搭配主板选用微星的B360M MORTAP支持九代酷睿处理器,也支持双M.2。做工均衡优秀。同样的搭配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。

  方案3

  这两套方案3是一个4.5k价位较均衡配置。除了显卡与INTTEL方案3的电源外,其他配置均和方案2差别不大。

  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。

  至于GX450与GX550系出同门,450W在这个方案中也是妥妥的够用,但是如果想要更多的冗余的话,可以换用GX550。

  方案4

  这两套方案4为4K价位段的较低价配置,主要配置与方案3相一致,但是在内存条方面只有8G单通道,SSD也仅为250G,这两套配置就可以提供目前流畅3A中高特效的入门水平,也提供入门生产力的水准,后期有更高需求的话可以自己加装内存条和SSD。

  总结一下:这八套配置各有侧重点,如果你对其中某一个方面有其他想法,可以在给出的推荐范围内自己选择替换,例如你可以加价上R5-3600/X或i5-10400F配RTX2060等,或者将B450M换成B550M这些都可以,只要不构成太大的性能瓶颈。都是没有问题的。

  7K以上价位段(进阶玩家/更好的生产力)

  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。

  下面给出大概参考方案

  在这两个方案中,AMD选择了3700X,R7-3700X为八核十六线程,频率为3.6-4.4GHz。INTEL选择了i7-10700K为八核十六线程,频率为3.8-5.1GHz。

  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。

  但是需要提醒的是,新30系显卡已经发布并且即将面市,新的30系列显卡性能提升巨大,并且相比较于20系列显卡,价格并没有太大的波动,使用你需要高端显卡加持的话,建议现阶段可以使用一张千元级别的GTX1650之类的显卡进行一个过渡。并且在新的30系显卡之上,因为功耗提升巨大,建议配备850W左右的电源。

  电源方面750W的电源,留有一定冗余,可以有效支持整机功耗。并且这个电源为金牌全模组,更好方便理线。

  总结一下:7K以上价位段已经有了非常丰富的选择,例如机箱可以更换其他配置,SSD也可以换成同档次的西部数据SN750等等,各位可以根据自己目前的需求,进行相应的加减档配置,请结合自己实际使用情况出发。

  最后一个大总结

  正值开学季前,因为有众多的攒机需求使用推出此DIY攒机安利,但是由于目前市面上相对应产品众多,并不能做到完整的推荐安利,只能在一个大致范围内进行推荐,特别是近几年ITX配置逐渐增多,但是由于ITX产品众多,并且需要更多地考虑兼容性,所以在此次配置推荐中以M-ATX列举,有ITX需求的小伙伴,可以根据此推荐组装相对应档次ITX产品。但是在其中请你们对于尺寸及其散热等影响情况需要更加关注。

  其次,各位如果选择携带主机前往学校请你们在搬运过程中需要更加注意,特别是显卡及散热器等较脆弱部分,最好进行拆卸以免发生意外。并且需要考虑宿舍实际情况,是否限电,空间是否可以容纳等等。

  而图表中列出价格为参考京东及天猫得出的大致中位数价格,也可以提供一个大致参考。

  最后,祝各位顺利装机,愉快进入大学校园,开启你绚丽的大学生活,也希望你能利用好你组装的装备,更好的提升自我,百尺竿头更进一步。

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。
