Inside forward, the former Google employees Adrian Aoun idea of the doctor's office of the future

بسم الله الرحمن الرحيم

السلام عليكم ورحمه الله وبركاته

A new kind of future doctors office launched its first site in the heart of the financial district in San Francisco at the beginning of this year. Some in the industry had their doubts about the health of the doctor's office with fitness tools like body scanner, a stethoscope and her own lab at home.

So we asked the founder of Google employees and former Adrian Aoun to show us around the place.

Of course, seeing and testing are two different things. We can not verify the authenticity of this proprietary tools for ourselves at this point, we still do not know how to start a lot of help and filed so far, but hopefully enough to ensure the fancy tools give patients an accurate reading.

What we do know is the forward taken in money from quite a few companies solid project like Khosla, Founders Fund, the first capital round, SV Angel, as well as angel investors John Doerr, Eric Schmidt, Marc Benioff, Garrett Camp, Aaron Levy and Joe Lonsdale, the one can hope they did due diligence on this new endeavor.

5G specifications

7:17 ص Unknown لا يوجد تعليقات

السلام عليكم ورحمه الله وبركاته

The total download capacity for a single 5G cell must be at least 20Gbps, the International Telcommunication Union (ITU) has decided. In contrast, the peak data rate for current LTE cells is about 1Gbps. The incoming 5G standard must also support up to 1 million connected devices per square kilometre, and the standard will require carriers to have at least 100MHz of free spectrum, scaling up to 1GHz where feasible.

These requirements come from the ITU's draft report on the technical requirements for IMT-2020 (aka 5G) radio interfaces, which was published Thursday. The document is technically just a draft at this point, but that's underselling its significance: it will likely be approved and finalised in November this year, at which point work begins in earnest on building 5G tech.

I'll pick out a few of the more interesting tidbits from the draft spec, but if you want to read the document yourself, don't be scared: it's surprisingly human-readable.

5G peak data rate

The specification calls for at least 20Gbps downlink and 10Gbps uplink per mobile base station. This is the total amount of traffic that can be handled by a single cell. In theory, fixed wireless broadband users might get speeds close to this with 5G, if they have a dedicated point-to-point connection. In reality, those 20 gigabits will be split between all of the users on the cell.

5G connection density

Speaking of users... 5G must support at least 1 million connected devices per square kilometre (0.38 square miles). This might sound like a lot (and it is), but it sounds like this is mostly for the Internet of Things, rather than super-dense cities. When every traffic light, parking space, and vehicle is 5G-enabled, you'll start to hit that kind of connection density.

5G mobility

Similar to LTE and LTE-Advanced, the 5G spec calls for base stations that can support everything from 0km/h all the way up to "500km/h high speed vehicular" access (i.e. trains). The spec talks a bit about how different physical locations will need different cell setups: indoor and dense urban areas don't need to worry about high-speed vehicular access, but rural areas need to support pedestrians, vehicular, and high-speed vehicular users.

5G energy efficiency

FURTHER READING

The 5G spec calls for radio interfaces that are energy efficient when under load, but also drop into a low energy mode quickly when not in use. To enable this, the control plane latency should ideally be as low as 10ms—as in, a 5G radio should switch from full-speed to battery-efficient states within 10ms.

5G latency

Under ideal circumstances, 5G networks should offer users a maximum latency of just 4ms, down from about 20ms on LTE cells. The 5G spec also calls for a latency of just 1ms for ultra-reliable low latency communications (URLLC).

5G spectral efficiency

It sounds like 5G's peak spectral efficiency—how many bits can be carried through the air per hertz of spectrum—is very close to LTE-Advanced, at 30bits/Hz downlink and 15 bits/Hz uplink. These figures are assuming 8x4 MIMO (8 spatial layers down, 4 spatial layers up).

5G real-world data rate

Finally, despite the peak capacity of each 5G cell, the spec "only" calls for a per-user download speed of 100Mbps and upload speed of 50Mbps. These are pretty close to the speeds you might achieve on EE's LTE-Advanced network, though with 5G it sounds like you will always get at least 100Mbps down, rather than on a good day, down hill, with the wind behind you.

The draft 5G spec also calls for increased reliability (i.e. packets should almost always get to the base station within 1ms), and the interruption time when moving between 5G cells should be 0ms—it must be instantaneous with no drop-outs.

Between the election and Inauguration Day, New York City has spent about $ 24 million to provide security at the Manhattan home of President.

Gina Cherelus

NEW YORK, February 22 (Reuters) - The cost of New York City for 24 million $ to provide security in the Trump Tower, home of the skyscraper President Donald Trump in Manhattan, from election day to inauguration day, or $ 308,000 per day, said New York Police Commissioner day Wednesday.

Revelation prompted renewed calls to Congress that the city pay to cover the costs of protecting your Trump headquarters on Fifth Avenue in Manhattan, where his wife and son are still in residence.

"We are seeking full federal recovery for all costs incurred related to the security of the president and his family Trump in the Trump Tower" Freddie Goldstein wrote, spokeswoman for Mayor Bill de Blasio, in an email to Reuters.

He said New York City Police Commissioner James O'Neill in a statement that the Ministry of Police now has a dual role in protecting the first family during the service, and also to protect the population in the city.

"Trump Tower now displays the same target for those who wish to commit terrorist acts against our country from a lack of resources are limited to the fight against terrorism," said O'Neill.

It could not be reached speakers Trump immediately for comment.

De Blasio asked the United States government in December for up to $ 35 million to cover security costs to protect Trump at his home on top of the 58-storey skyscraper, which is located on Fifth Avenue near Central Park, which is a popular area with tourists.

At $ 24 million, and the final cost was less than that. Trump has spent most of his time on election day, November 8th until his inauguration on January 20 in his penthouse apartment in the Trump Tower.

In addition to police protection, fire department incurred $ 1.7 million in costs during the period of time Trump was in New York, according to O'Neill.

O'Neill said the first lady Melania Trump days and the couple's son, Baron, are the only ones in the city, and security to move forward cost between $ 127,000 and $ 145,000 a day less than it was when he was president in the residence.

O'Neill said when Trump in the city, the cost of police protection, return to $ 308,000 on average per day. It will cost about another $ 4500000 annually for the fire department in New York City to protect the building.

"We expect that these costs increased significantly as the president in New York City," he said.

It was not a trump card back to Manhattan since his inauguration.

According to the New York congressional newspaper. Carolyn Maloney said in a statement on Wednesday that the taxpayers of the city should not be forced to pay for the "national security commitment," and that he (Reporting by Gina Cherelus "Congress must provide the taxpayer city full payment"; Editing by Sharon Bernstein and Leslie Adler)

During the presidential campaign in 2016, he reported about how safe the e which is run by the Trump Organization's service to anyone with a little knowledge of computers can almost everything presents for Trump and his campaign.

Now, some unknown hackers calling itself "Pro_Mast3r" was able to distort the official website associated with fundraising presidential campaign President Donald Trump on Sunday.

Pirates, who claim to be from Iraq, said server distortion, secure2.donaldjtrump.com behind the content management system in the CloudFlare platform security.

Server appears to be the official campaign Trump server, according to Ars, and the server certificate is legitimate, "but said, referring to a picture on another site is not secure, which led to a warning on Chrome and Firefox that connection is not secure."

Distortion display an image of a black man hat site included a text message, which reads:

At the time of writing this report, the server is now offline, there is no official statement from the Trump penny campaign team yet.

According to the latest Ndwinh President Donald Trump's website hacked; Iraqi distortion hacker published by journalist Paolo Attivissimo technology that, does not contain the source code of any software distortion malicious script server.

Instead, it includes a server up to JavaScript on the now non-existent account Google blog, "masterendi", which was linked to cyber attacks on three other sites in the past.

السلام عليكم ورحمه الله وبركاته

Microsoft once again face the embarrassment for not correcting weaknesses in time.

Yes, I have again the project team zero Google publicly disclosed vulnerability (with POC exploit) affecting Microsoft Windows operating systems ranging from Windows Vista Service Pack 2 for the latest Windows 10 that have not been corrected.

A few months ago, search engine giant Windows critical weaknesses to the public only ten days after the disclosure of a bug to Microsoft revealed.

However, this time Google revealed the weakness in the Windows operating system to the public after that Microsoft has failed to correct it within the framework of 90 days provided by the company.

The zero project by Mateusz Jurczyk Google responsible security vulnerability in a library (GDI) and the graphics device interface for Windows' Microsoft Security team on June 9 last year.
The weakness affects any program that uses the library, and if exploited, could allow hackers to steal information from memory.

While Microsoft has released a patch for the weakness in the June 15, the company does not fix all the issues in the GDI library, forcing the project to zero researcher reported back to Microsoft with proof-of-concept on 16 November.

"As a result, it is possible to reveal bytes uninitialized or outside the boundaries of the pile through the color pixels, in Internet Explorer and other customers GDI that allows the extraction of the displayed image data to the attacker," Jurczyk notes in a new report.

Now, after giving a grace period of three months for the company, Google released the details of exposure of the public, including hackers and malicious actors.

Project Zero Google team routinely find security holes in various programs, and calls for software vendors affected publicly to detect bugs correction within 90 days of discovery. If not, the company automatically makes bugs along with the audience details.

Although Windows users need not panic, hackers will require physical access to the host machine to exploit the weakness, the Redmond giant is to launch emergency patch released before it is developed sophisticated exploits.

Microsoft recently delayed this month's Patch Tuesday for a month because of "the issue at the last minute that could be some customers and not resolved in a timely manner affect for the planned updates [Microsoft]," in the February 14.

Therefore, if there is not expected emergency patch this month, will be leaving this gap was unveiled recently open to hackers for almost a month to exploit - just as we saw last time when Russian hackers actively exploiting the then unpatched Windows kernel error in the wild - which means that the users Windows in the potential risks.

A group of highly sophisticated hackers state-sponsored spying on the Israeli army by hacking the personal Android phones for soldiers to control the activities of individuals, and data theft.

The newly released search by Kuyt and Kaspersky suggests that believed more than 100 Israeli soldiers from the Israel Defense Forces (IDF) to targeted with spyware.

Called ViperRAT name, and has been specifically designed malware to kidnap Israeli soldiers smartphone "Android-based and after exfiltrate valuable data, including images and audio recordings, directly from the risk devices.
Mode of action have been identified
According to security companies, and members of the Israel Defense Forces has been breached by social engineering techniques - where he was luring soldiers through Facebook Messenger and other social networks to enter the communications with the hackers who were on the attractiveness of various countries such as Canada, Germany, Switzerland and women.
Then the soldiers were tricked to install a version trojanized two different, usually legitimate Android apps chat, chat and Real YeeCall Pro, to facilitate communication.
As it has been the distribution of malware using the dropper hidden in the smart phone applications and other Android including billiards game, the player Israeli love songs, and transfer to the application IOS, which is shared between Israeli citizens and available in the Google Play store.

The application then scanned soldiers smart phones and downloading malicious applications that masqueraded as an update to last a pre-installed applications, such as WhatsApp, and deceive the victims to allow different permissions to carry out surveillance.
This, in turn, allows an attacker to execute commands on demand, enabling them to control the phone's microphone, camera, and eavesdrop on conversations soldiers, peers in the footage live cams.
In addition to this, malicious ViperRAT software combines a wide range of data from computers at risk including geolocation, Call Log, personal photographs and text messages, cell phone tower information, and network and metadata device, surf the Internet, download the application date.
