I’m a long-term cryptocurrency believer, pretty saddened to see the space degenerate into something about as interesting and brimming with emergent properties as an unregulated penny-stock market.

But there are still some genuinely interesting, technically

Apple’s MacBook Air turns 10

Ten years ago today, Steve Jobs triumphantly held up a manilla interoffice mail envelope to a round of applause at the Moscone Convention Center in San Francisco. It was a silly gimmick, but it got the point across. A year after introducing the Macworld crowd to the iPhone, the company was about to add another cornerstone product to its


NRI stuck at Delhi airport for 3 days, passport travels to Canada

A Bahrain-bound NRI has been stranded at the Delhi’s Indira Gandhi International (IGI) Airport for the past three days after his handbag containing his passport was mistakenly taken away by a passenger to Canada.

Satyendra Singh said he arrived in Delhi from Lucknow on Saturday and was in transit to Bahrain.

On Saturday afternoon, I reached Delhi and went for security check to catch the international flight. The queue was long so I put my handbag in the scanner. By the time I reached for check and crossed it I could not find my bag. I informed the security, who checked the CCTV footage and found that another passenger took the back and boarded the Air Canada flight. The flight had already departed by then,” said Singh, a US national, working in Bahrain. e Canada-bound passenger had reportedly taken Singh’s bag leaving his own behind.

The ordeal had just started for Singh as he was left with no money or clothes. He spent the night on the floor of the terminal as he could not leave the terminal due to security reasons. His immigration had been cleared in Lucknow, so he could not even go back.

I informed my family and they said they will send some money so that I could buy food. But there was no way they could have contacted me. Finally, On Sunday, Air India shifted me to the lounge and I am currently here. Besides the passport, my handbag had my medicines,” he added.

Singh had come to India to meet his parents, who live in Lucknow. The Central Industrial Security Force (CISF) said they could not do much as the security protocol does not allow a passenger to return unless he has a passport.

The airlines, however, acted promptly and the Air Canada flight, carrying Singh’s bag arrived at Delhi airport on Monday evening. Air India, however, said Singh will have to pay the fare difference as hand baggage is not the responsibility of the airline. He is expected to depart by Monday night.

Guardiola urges City to learn from Anfield pain

Guardiola urges City to learn from Anfield pain

Guardiola's side saw their 30-match unbeaten run in the Premier League come to a stunning end at Anfield on Sunday.

The leaders fell behind to Alex Oxlade-Chamberlain's early opener and although Leroy Sane equalised before half-time, City were blown away by three goals in nine second half minutes from Roberto Firmino, Sadio Mane and Mohamed Salah.

Although late goals from Bernardo Silva and Ilkay Gundogan put a flattering gloss on the scoresheet, City boss Guardiola had no complaints about his side's first league defeat since April 5 at Chelsea.

It was City's first domestic defeat since an FA Cup semi-final against Arsenal on April 23.

Conceding that all the talk of City winning the title at a canter and possibly going unbeaten throughout the entire season made it hard to keep his players motivated, the Spaniard said: "In every press conference for the last few months you have said that the Premier League is done.

I always said no. It is still to be done. Sometimes the worse thing is when people say from one month ago that it is over.

It's so difficult to maintain this run, especially against good teams like Liverpool.

Football is an unpredictable game. We have to fight until the end to win the league.

Guardiola admitted City had lost their composure in the second half after being rattled by Liverpool's relentless pressing and the ferocious Anfield atmosphere.

We lost a lot of balls. Liverpool are so aggressive without the ball and we had little bit of a problem to control that," he said.

We started the second half good until the goal from Firmino. After that we lost our control and we become involved in the environment at Anfield.

Although City's lead at the top can be cut to 12 points if second placed Manchester United beat Stoke on Monday, they remain firm favourites for the title.

Guardiola, who will be without defender Fabian Delph for several weeks after his first half injury, believes City will use their Anfield frustration to bounce back in their next game against Newcastle.

Now we must be positive, analyse why we lost and look to the game against Newcastle," said Guardiola, who refused to reveal if he is still in the hunt to sign Arsenal's Alexis Sanchez.

It's never good news to lose, but when you lose it's important not to lose again.

We have a young team and maybe it can be good for the future.

I've won a lot of titles and always I've dropped points on the way.

For Liverpool boss Jurgen Klopp the victory was a cathartic moment after City thrashed his team 5-0 earlier this season.

It was also significant because it proved Liverpool can still thrive without Brazil forward Philippe Coutinho, who got his wish to join Barcelona earlier this month.

To score four in the week after Phil Coutinho leaves the club is a very big statement," Klopp said.

It's not like we held a meeting and said 'guys can you win today because then no-one will talk about Phil.

But of course it was important to show it's possible to play well without him.

Unlike the rest of the Premier League this season, Liverpool found the formula to knock City out of their stride.

Klopp believes the game -- undoubtedly one of the best in England this term -- showed the need to be fearless when facing a team of City's class.

Maybe it was a historical game, it could be the only one they lose in the entire season," Klopp said.

They are so strong but I really think we deserved it. You need to be brave, you need to play football.

You can sit in your box and hope they don't score but that's not really likely.

We are Liverpool, so we shouldn't play that way. We have to attack. There is no alternative against City.
