The photograph shows an early prototype of the Apple iPhone 8 with a fingerprint reader on the back. Oddly, there is no physical home button on the front either thanks to the massive display which takes up the entirety of the front face. The leaked images also reveal a vertical dual camera with the flash placed below the camera setup, it looks like the phone is almost bezel-less.

This alleged render is countering the current rumours, which claim that the fingerprint sensor to be embedded into the display of the device.

Gizbot.com, tipster Benjamin Geskin, has claimed that these renders are fake and suggests that the upcoming iPhone will be having a Touch ID embedded under the display itself. While both the theories have their doubters and believers it waits to be seen as to what Apple’s tenth anniversary iPhone will pack in.


Apart from the leaks and renders the iPhone 8 is expected to feature an OLED display panel, wireless charging, AR features, a 3D front camera and is said to be powered by the A11 SoC (System on a Chip) with iOS 11 running the show on the software front. The expected base launch price in India has been rumoured to be around Rs 81,600.

Tech: Facebook Extends Security, Set to Use 'Disaster Maps' To Mitigate Calamities

Facebook is now extending its hand to save lives during natural calamities and disaster by creating
disaster maps.


Their project found its inspiration from the Peru floods that took place earlier this March. According to a report, the flood took 100 lives, leaving thousands misplaced. According to the Facebook press release video, those floods were trending on their platform, which gave them three coordinates to start with their project.

These coordinates were firstly, the location of the people during the disaster, which they called ‘the location density map’. Secondly, it allowed Facebook to track their movement in various neighbourhood areas during such emergency, which they call ‘movement maps’ and lastly, the location where they were checking themselves safe or ‘safety check maps’.

Using an ‘aggregated, de-identified Facebook data’, which could be used to share information to organizations, this disaster map was created. Thus, allowing Facebook to hint to these relief organizations where their life saving efforts were actually needed.


By the use of census information of the affected region and satellite images they intend to keep track of the human population and provide safety nets accordingly. They have also used neural network technology, through their Facebook image recognition engine, to work on this system.

It would be interesting to see them work on connecting these organizations to those affected in remote areas such as villages or places where the internet connectivity is poor and usually gets worse when a calamity strikes.

Organisations working closely with Facebook are UNICEF, the International Federation of the Red Cross, the Red Crescent Societies and the World Food Programme.

Currently, Facebook has an option of Safety Check, which allows users to mark themselves, friends and family safe, during various points of crisis, such as an earthquake, terror attacks and cyclones. Launched in 2014, this option allows people to reconnect with their friends and families during crisis.

An official statement released in Abuja by BudgIT Nigeria indicates that up to 20 states owe their workers including pensioners their entitlements ranging from one to 36 months.

BudgITng said it decided to conduct a qualitative analysis of the frequency of salary payment of six different categories of workers in all the 36 states.

A part of the statement read; “In particular, we discovered that many states have defaulted in the payments of pensions and gratuities.

“From the survey carried out, we discovered that apart from the fact that 16 states which are yet to pay the pensions of former civil servants in their service, 8 of these states have not paid their pensioners at least 12 months’ pensions.

“Notably, these pensioners expressed how unhappy they are, their dissatisfaction with the government and how hard it has been for them to survive.

“In addition to outstanding pensions, we note from our survey, that across all categories, states like Kogi, Abia, Benue, Oyo, Ekiti and Ondo have not paid their workers’ salaries for this year 2017; owing at least 4 months’ salary. However, the likes of Lagos and Rivers have been consistently impressive with their up to date and full payment of civil servants’ remuneration."

Sport: Who Is Romelu Lukaku Following?, Everton, Chelsea or Man United?

Everton striker Romelu Lukaku is a man in demand.

Chelsea and Manchester United are said to be keen on the big Belgian, who has told Everton he is eager to move in search of Champions League football.

Lukaku, 24, claims he knows where he is playing next season but where is best for him? ESPN FC's club bloggers from Everton, Chelsea and Manchester United have their say on the £100 million-rated striker's future.



EVERTON
Lukaku and international breaks seem to coincide with the striker discussing a future away from Goodison Park. His ability in front of goal matches his knack for needless musings on his future. That said, Everton would undoubtedly be in a much stronger position if Lukaku remains beyond this summer. The media circus attached to the player is a minor inconvenience when weighed against his influence on the pitch.

Manager Ronald Koeman could potentially do a lot with a reported asking price of £100m but a sizeable budget is no guarantee for replacing the productivity of a player directly contributing 50 percent of Everton's 62 league goals last season (25 goals, six assists). A staggering 20 goals separated Lukaku and nearest teammate Ross Barkley (five).

In Lukaku, Everton possess a proven and reliable scorer, one that has improved under Koeman and will continue to do so.

His record shows 87 goals in 166 matches (155 starts), putting him level with Alex Young and above Alan Ball and Tommy Lawton on goals scored in royal blue. Only 15 players in Everton history have scored more goals for the club. It may be wishful thinking to expect this ambitious 24-year-old to play a fifth successive season without Champions League football, but the two years left on his contract and his indisputable importance to the team are why Everton should do everything to coax at least one more season from Lukaku. -- Luke O'Farrell


CHELSEA
If Diego Costa does depart, Lukaku would be an excellent replacement. Although not an exact replica of the Spain international, his ability to lead the line, decent turn of foot and the use of his physicality to dominate defenders would suit Chelsea's style of play. Lukaku's work rate has often been criticised though that would certainly improve under the demanding Antonio Conte and in a team where he is far from being the only big name.

Having spent his teenage years dreaming of emulating his idol Didier Drogba by scoring goals for Chelsea, the motivation for him to succeed would be huge. He would also need little time to acclimatise to his new environment having already spent three years on Chelsea's books, something that would not be the case at Old Trafford.

His previous spell might not have worked out too well for either party but as a more mature individual and with his game having vastly developed in the interim, he is guaranteed to have a far greater impact second time round. The presence of his Belgian compatriots Eden Hazard and Thibaut Courtois will make him feel even more at home and could help him hit the ground running if he was to return to Stamford Bridge. -- Phil Lythell


MAN UNITED
Lukaku is one of several signings Manchester United should be looking to make, and what's not to like about him? He has youth, speed, technique, and a high footballing IQ; he has strength in the air, strength in possession and the ability to play in those around him.

He would be the ideal foil for Henrikh Mkhitaryan and Paul Pogba, and would be an outstanding fit alongside Antoine Griezmann should the Frenchman eventually make the move from Atletico Madrid. He scored 25 goals for Everton last season, with six assists, highlighting what a well-rounded player he is and how well-suited he is to English football.

Indeed, he has 87 goals in 166 matches for Everton, which is a very fine strike rate. He has all the ability to be a genuine goal threat in the Champions League, and should be aggressively courted by United, even though there will doubtless be strong interest from rivals both home and abroad.

His age and his talent would make him an excellent acquisition for Jose Mourinho, and the rapid development of his game in recent seasons suggests that he is only set to improve. -- Musa Okwonga

Agent to Arda Turan Says He Is Not Leaving Barcelona Despite Report Move to Arsenal or China

Arda Turan will not leave Barcelona this summer despite reports that a move to Arsenal is at an advanced stage, his agent has said.


Turan, 30, has struggled to break into the side on a regular basis since joining from Atletico Madrid in 2015, and his subdued celebration after last month's Copa del Rey triumph was interpreted by some reports as a sign of his impending departure.

The Chinese Super League has been mentioned as a possible destination, but recent reports suggest Arsenal are now best placed to land Turan if he leaves in the summer.

But the Turkey international's agent Ahmet Bulut told reporters: "Arda's not going anywhere. Barcelona are happy with him and we've not spoken with any club about a transfer.

"The news being reported about him leaving the club annoys Arda. The board don't like the rumours either. Arda Turan will finish his contract -- he will stay until 2020."

However, reports in Spain have said Turan, along with defender Jeremy Mathieu, would be allowed to leave for the right fee as new coach Ernesto Valverde looks to reshape the squad.

Injuries and the fierce competition for places saw him end last season on the periphery of the first team.
