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.。

Brackets announced for Sydney 2022 ATP tennis tournament******

SYDNEY, Dec. 7 (Xinhua) -- The ATP Cup announced on Tuesday the group brackets for the upcoming tournament that will take place in Sydney, Australia from January 1 to 9, 2022.。

The ATP Cup will feature 16 country teams, five players each team, in four groups. They will fight over a prize pool of more than 14 million Australian dollars (about 9.87 million U.S. dollars), an increase from the 10 million Australian dollars (about 7.05 million U.S. dollars) that was up for grabs in 2021.。

World No. 1 Novak Djokovic was confirmed to be among the competitors for the top seeding country, Serbia, despite previously refusing to disclose his vaccination status after the Australian Open announced all players must be vaccinated.。

Under current laws, the New South Wales (NSW) government would need to give Djokovic an exemption to enter Sydney and he would be required to complete 14 days of quarantine.。

"Top seed Serbia, headlined by world No. 1 Novak Djokovic, will lead Group A, which will also feature Norway, Chile and Spain," read the ATP announcement.。

He will compete against the defending champion and world No. 2 Daniil Medvedev, playing for Russia in Group B which includes Italy, Austria and home nation Australia.。

Group C will include Germany, Canada, Britain and the United States. Greece, Poland, Argentina and Georgia will compete in Group D.。

Other top contenders include Alexander Zverev playing for team Germany, Stefanos Tsitsipas playing for Greece, and Andrey Rublev playing for Russia.。

For the home team world No. 34 Alex de Minaur and No. 49 James Duckworth will compete for Australia.。

ATP Chief Tour Officer Ross Hutchins said the 2022 line-up "speaks for itself" and Sydney would make an ideal place to kick off the 2022 tennis season.。

"We're delighted that fans will be able to see so many of the world's best representing their countries in the opening week of the season and we look forward to a fantastic event," said Hutchins.。

The third annual 2022 ATP Cup will span nine days in two Sydney tennis venues - the Ken Rosewall Arena and Qudos Bank Arena both in Sydney Olympic Park. Enditem。

12月了为什么还那么暖?不要着急 两次降温雨雪在路上了******

  持续的天气晴朗天气让许多西安市群众疑虑,以前有信息说明年会遭受极寒冬季,怎么到如今或是暖融融的呢?不要着急,连续两次雨雪、吹风机天气将要到达,立刻就能感受到寒风凛冽了。

  预测分析的严冬如何一直暖融融?

  在2021年11月还未宣布立冬时,有最新消息称,2021年大家有可能遭受极寒冬季。殊不知,采暖至今,西安市还未发生尤其突出的降温雨雪天气,近期几日,也是不断天气晴朗,每日都感覺到暖融融的,这是怎么一回事呢?极寒冬季还会继续来吗?

  对于此事西安气象局权威专家表明,2021年西安冬天温度贴近长期,时节内冷热起伏大。 预估 2021/2022 年冬天平均温度0~3°C,与长期同比增加,贴近长期。

  2021年冬天时节内温度分阶段转变特点显著,主要表现为前冬暖后冬冷的趋势分析。依据预测分析,2022 年 1 月中下旬—2月中下旬发生分阶段超低温雨雪天气的概率大。

  我国将发生2次降温雨雪天气。

  依据山西省气象局全新气象预报,受西风酒槽危害,6日至8日,我国自北向南将发生一次雨雪、风大天气全过程,我省绝大多数地区有降雨。

  6日夜里至7日大白天,陕北高原一部分地区有零星小倩、中西部有小到中雪,陕西关中中西部、北边及秦巴山区有雨夹雪或小倩、局部地区中雪,关东南部、陕南大部分有毛毛雨。

  7日夜里至8日大白天,陕北高原有小到中雪、中西部局部地区有降雪,陕西关中中西部、北边及秦巴山区有雨夹雪或小到中雪、局部地区降雪,关东南部、陕南大部分有毛毛雨或雨夹雪。

  6-7日陕北高原有5级上下东南风、龙卷风6~7级,陕西关中北边、渭南有5级上下偏车风,龙卷风6~7级。8日陕北高原有5~6级偏西风。

  受强冷空气危害,6日陕北高原溫度将降到-9~-7℃,陕北高原南边、陕西关中、渭南及秦巴山区溫度将降到-5~-3℃,7日陕南溫度将降到-2~0℃。

  此外,9日夜里至12日前后左右我国将有一次强降温、雨雪天气全过程,请密切关注天气转变。

  降温天气很有可能对农牧业造成危害。

  本次全过程关键以降温、降水和长时间不断阴雨寡照多要素累加危害为主导,对我省设施蔬菜、畜牧养殖造成非常大的危害,很有可能造成温棚大棚膜撕破、病虫害冻害冷害加重、销售市场蔬菜销售紧缺、羊牛等牲畜体感温度减少等气候灾害伤害。

  为安全性解决本次降温降雨寡照天气很有可能造成的不良危害,提议采用如下所示对策:

  本次降温降雨寡照延迟时间长,对设备农作物危害非常大,提议提早结构加固大棚膜,避免 风大撕破大棚膜导致损害,与此同时做好温棚柔光灯、升温、降湿等温棚小气候调节和病虫害防止工作中。

  运用降温前的6、7两日天气晴朗天气时间段,降低棚里自然通风抗压强度,提升发热量堆积,提升棚温,以解决降温全过程产生的棚里超低温低湿自然环境,保证 棚里农作物安全性,与此同时做好隔热保温机器设备的维护保养,防止雨雪冷冻危害一切正常运作。

  现阶段已进到过冬超低温期,雨雪降温天气很有可能导致土壤层结冰、泥泞不堪,造成过冬露地栽培蔬菜水果采摘艰难,提议提早做好采摘贮藏工作中,防止发生蔬菜水果市场需求紧缺状况。

  将来西安将发生2次雨雪、吹风机天气全过程。

  西安气象局12月5日13时30分公布关键天气汇报:受西风酒槽危害,7日西安将发生一次雨雪、吹风机天气全过程。预估降雨主要发生在7日黄昏到晚间,平原区地域有毛毛雨或雨夹雪,秦岭山里有小到中雪。在其中,7日本市有3~4级偏车风,龙卷风可达5~6级。

  此外,10-11日西安将迈入一次较显著的雨雪、降温天气全过程,请密切关注天气转变。

  西安气象局特别提醒:本次全过程以雨雪、吹风机为主导,秦岭山里有下雪,需尤其注意防范其致使的路面泥泞不堪、降雪结冻、低可见度等对城市交通的不良危害。报请有关部门做好预防措施,降低雨雪、风大天气对农牧业、畜牧养殖、城市交通等的不良危害。提示群众密切关注气象局公布的全新气象预报预警信息,留意防冻保暖和安全出行。

  预估西安地区12月6日大白天晴转多云,0℃~11℃;7日阴雨天,偏车风3-4级,龙卷风5-6级,3℃~11℃;8日毛毛雨或雨夹雪转阴天,秦岭山里有小到中雪,1℃~9℃。
