Fire safety education is nothing new in schools, but the way fire departments communicate with the public and what information they share continues to evolve.

The University of Washington may have just solved Wi-Fi power consumption problems once and for all. A group from the the University’s engineering department have created a Wi-Fi system that, according to them, uses 10,000 times less power than traditional Wi-Fi. “Passive Wi-Fi” as the team calls it, is compatible with current smartphones and routers.
According to a video describing Passive Wi-Fi, traditional Wi-Fi radios consume a lot of power mainly because of the analogue radio frequency (RF). In order to reduce power consumption of Wi-Fi radios in smartphones and digital devices, the Passive Wi-Fi only uses the digital baseband while the analogue RF band is delegated to a single plugged-in device.
Essentially, Passive Wi-Fi helps remove the power hungry analogue RF from the picture, which will make you smartphone last a whole lot longer.
The plugged-in device is used to send the wave RF signal to the Passive Wi-Fi device which then generates Wi-Fi packets and sends it to existing devices including smartphones.
The team has managed to achieve download speeds of up to 11Mbps which falls in line with most LTE download speeds. However, the team is now working on increasing the throughput.
The team say that this new technology will allow for new kinds of communications that was not possible before due to the power requirements of current Wi-Fi systems.
“We wanted to see if we could achieve Wi-Fi transmissions using almost no power at all. That’s basically what Passive Wi-Fi delivers. We can get Wi-Fi for 10,000 times less power than the best thing that’s out there.”- Shyam Gollakota, assistant professor of computer science and engineering, University of Washington.

Universities and NHS trusts in England have been hit hard by ransomware in the last year, according to Freedom of Information requests carried out by two cybersecurity firms.
Bournemouth University, which boasts a cybersecurity centre, has been hit 21 times in the last 12 months.
Twenty-eight NHS Trusts said they had been affected.
Ransomware is a form of computer malware which encrypts files and then demands a ransom for their release.
It can travel via email or hide in downloadable files and programmes from corrupted sites and applications, and the ransom is usually payable in bitcoins.
Cybersecurity firm SentinelOne contacted 71 UK universities. Of the 58 which replied, 23 said they had been attacked in the last year.
None of them said it had paid a ransom but the largest sum demanded was five bitcoins (about $2,900 or £2,200), the firm said.
Only one university had contacted the police.
According to the report, two of the institutions said they did not use anti-virus software. Both have been contacted for comment.
Bournemouth University confirmed the attacks but said: “It is not uncommon for universities to be the target of cybersecurity attacks; there are security processes in place at Bournemouth University to deal with these types of incident.”
It added that there had been “no impact” on its activity as a result of the attacks.
In a separate study, security firm NCC Group asked every NHS Trust in England whether it had been a victim of ransomware.
Of the 60 responses, 28 said they had experienced an attack, one said it had not and 31 declined to comment on the grounds of patient confidentiality.
“Paying the ransom – which isn’t something we would advise – can cost significant sums of money, yet losing patient data would be a nightmare scenario for an NHS Trust,” said Ollie Whitehouse, technical director at NCC Group.
According to the US government, ransomware attacks in America have increased in frequency by 300% year on year in 2016, with 4,000 incidents a day now being reported.
It advises that “prevention is the best defence” and suggests the use of spam filters, firewalls, anti-virus programs and employee training for businesses – as well as regular data back-ups.
If a computer is infected it should be removed from any network and switched off as soon as possible.

After months of beta updates, Android Pie was finally released in its stable avatar earlier this month. The update has started rolling out to the Pixel range of handsets as well as the Essential Phone. To strengthen its focus in the budget smartphone segment, Google on Wednesday announced the arrival of Android 9 Pie (Go edition), successor to last year’s Android Oreo (Go edition) that was unveiled back in December 2017. The latest update brings major features such as a boost to internal storage, faster boot times, security features like verified boot, and a dashboard to monitor data consumption.
Google also stated that the first devices with Android Pie (Go edition) will hit shelves later this Fall, however exact dates have not been mentioned. Existing smartphones that run Android Oreo (Go edition) are expected to get the major software update sometime later this year or early next year. These include phones like the Nokia 1, Lava Z50, Micromax Bharat Go, and the Spice F311.
The features coming to these budget smartphones with Android 9 Pie (Go edition) include up to 500MB of additional storage right out-of-the-box, claimed faster boot times, verified boot, and an accessible dashboard for data tracking. Android Pie (Go edition) will come with fewer preloaded apps and newer apps that are lighter. It will also have security features such as Find My Device built-in, and offline app install scans. “Collectively, these features help solve some of the most common pain points for entry-level device owners: storage, performance, data management, and security,” said Sagar Kamdar, Director of Product Management, Android.
Late last month, Google had updated its YouTube Go app with a new .yt file extension that allowed users with Android Oreo (Go edition) smartphones to save YouTube offline videos to their gallery. The Google Go app was updated with webpage voice dictation and a new Navigation for Google Maps Go extension app was released.
Google claims that more than 200 handsets, in over 120 countries across the globe, now run Android (Go edition) – and that more than 100 manufacturers already have plans to release similar phones before the end of the year.

“Daughters are the best,” Amitabh Bachchan, father of 43-year-old Shweta, has made it clear many times over on social media. His latest post show Shweta joining him for the weekly Sunday morning meet-and-greet ritual at the Bachchans’ Mumbai home. This isn’t the first or even the second time. Amitabh Bachchan frequently posts pictures of Shweta and granddaughters Navya Naveli and Aaradhya on social media with almost the same caption which reads: “Daughters are the best.” Just last week, Mr Bachchan shared pictures of Navya Naveli (daughter of Shweta and Nikhil Nanda) and Aaradhya (daughter of Abhishek and Aishwarya Rai Bachchan) and wrote: “Daughters be the best… granddaughters the bestest.” There are few corresponding posts for son Abhishek, almost none of grandson Agastya.
On Monday, he posted these pictures of Shweta at Jalsa with him on his social media platforms. On his blog he wrote: “When the daughter takes an interest in your actions on a Sunday at the gates of Jalsa, it fills one with pride and affection.”
On a previous Sunday, Amitabh Bachchan reserved his best smile for Shweta because… you already know.
Here are all the other times when Amitabh Bachchan reminded his fans that ‘daughters are the best.
Last year, around this time, Shweta hosted a surprise dinner for all the family members in Jalsa, which Amitabh Bachchan described on his blog as a “wonderful occasion out of nothing.” Of his daughter’s initiative he had said: “Daughters are very special and mine, Shweta, must be the most beautiful in the world. Daughters are the best.”
Amitabh Bachchan is currently filming Yash Raj Film’s Thugs Of Hindostan and will soon shift focus to Karan Johar’s trilogy Brahmastra, co-starring Ranbir Kapoor and Alia Bhatt. Amitabh Bachchan is awaiting the release of 102 Not Out, which also features Rishi Kapoor.
