Deafening boom over Edinburgh caught on Hive camera

The dramatic moment was recorded by Alison Beattie Jarvie, from her home in Leith, close to the Ocean Terminal.

“It was my Hive camera in my grandson’s bedroom,” the 40-year-old explained,“I didn’t even realise I had it on camera until this morning.”

Thankfully her 3-year-old grandson was not staying in the bedroom last night.

The Hive camera in the corner of the room captured the bright light that flashed across the sky at 4:46am, before the deafening crash of thundersnow that followed.

The rare weather phenomenon is caused when the air low to the ground is warm enough to cause a thunderstorm, while the air above it is cold enough to create snow.

As the snow falls, the lightning is reflected off tens of millions of snowflakes, making the storm brighter than usual.

Crypto Boom Shaken as Bitcoin Plunges Along With Other Coins

(Bloomberg) — Bitcoin and other digital currencies plunged Thursday, a slide likely to stoke speculation about the durability of the boom in cryptocurrencies.

Bitcoin slumped as much as 8.7%, the most since early August, while other digital coins like Ether posted double-digit percentage declines. The Bloomberg Galaxy Crypto Index at one point slid more than 6%.

“Conditions are very massively overbought and bound for a correction,” said Vijay Ayyar, head of business development with crypto exchange Luno. “So I don’t think it’s unusual frankly. I still believe we’ll see all-time highs before a larger drop/correction.”

Even with the retreat, Bitcoin has more than doubled this year and until recently was knocking on the door of the record high of $19,511 set in 2017. Crypto believers tout purchases by retail investors, institutions and even billionaires, as well as the search for a hedge against dollar weakness, as reasons why

Here’s Your Sonic Boom Weather Forecast!

Success for Aerion hinges on the ability of its planned AS2 business jet to fly in excess of the speed of sound over land without delivering a sonic boom. To do so, AS2 operators will have to account for, avoid and overcome weather conditions that could allow supersonic shock waves — the boom that humans hear — to reach the ground.

That means that AS2 owners and crews will need a sort of sonic boom weather forecast to be able to plan for boom-less flight over the U.S. or other territories.

Aerion says it has just the thing thanks to an agreement with micro-satellite operator Spire Global, whose weather data and forecasting capabilities will allow the AS2 to boom along over

Boom Supersonic plans demonstration flight in 2021

Aviation startup Boom Supersonic plans to fly a supersonic jet demonstrator in 2021, the company recently announced.

The XB-1 demonstrator will be 71 feet (22 meters) long and made of carbon composite, allowing it to remain resilient to flying faster than the speed of sound, the company said in an October statement. The ultimate goal is to create an airplane that will fly Mach 2.2, or 2.2 times the speed of sound.

“XB-1 is an important milestone towards the development of our commercial airliner, Overture, making sustainable supersonic flight mainstream and fostering human connection,” Boom founder and CEO Blake Scholl said in a statement.

Ghosts of dotcom boom in tech valuations

“The maths tells us in aggregate there will be considerable disappointment. But also, like 1999, the more interesting thing is the opportunity in companies that are not part of the mania. In 1999, the sectors being shunned were labelled the old economy. Today the shunned sectors include emerging markets and cyclical stocks,” Isles says.

There are of course differences in today’s technology stocks, according to Nathan Bell, head of research at InvestSMART, who says: “The dominant tech companies are perhaps the best businesses that we’ve ever seen and are extremely profitable.”

Buy now, pay later stocks like Afterpay have raised lots of capital based on their concept.  Louie Douvis

Hugh Dive, portfolio manager at Atlas Funds Management, says “Apple, Amazon, Facebook and Google are actually generating revenues and growing profits”. He adds: “What we haven’t seen in 2020 is the plethora of concept companies raising large amounts of capital solely

Falcon 9 rocket sent a new NASA
and European Space Agency satellite on its way to orbit from California on Saturday morning. The Sentinel-6 Michael Freilich satellite is the latest in a series of satellites that have provided critical data about sea level rise and climate change for almost three decades. It’s named for the former director of NASA’s Earth Science Division, Michael Freilich, who’s considered a pioneer in conducting oceanography work from orbit.

The new ocean-spying bird will be able to measure sea levels within a few centimeters for 90% of oceans around the globe. A twin satellite named Sentinel-6B will join the effort when it launches in

Green is the new black in boom for clean energy funds

LONDON (Reuters) – Investors are pouring money into green funds, banking on a Joe Biden presidency in the United States for a further boost to the renewable and alternative energy industry at the expense of traditional oil and gas businesses.

Shares in solar and wind energy businesses, electric vehicle companies and environmental technology pioneers have been on the rise for months, widening their lead over fossil fuel rivals since the U.S. presidential election on Nov. 3.

Even without U.S. President-elect Biden’s win, investors have been positioning for governments worldwide to enact more climate-friendly legislation. The UK, for instance, announced this week that it would ban the sale of new petrol and diesel cars and vans from 2030 to cut carbon

Boom In Demand For Friendly Hackers As 5G Approaches

As the number of online devices surges and superfast 5G connections roll out, record numbers of companies are offering handsome rewards to ethical hackers who successfully attack their cybersecurity systems.

The fast-expanding field of internet-connected devices, known as the “internet of things” (IoT) which includes smart televisions and home appliances, are set to become more widespread once 5G becomes more available — posing one of the most serious threats to digital security in future.

At a conference hosted by Nokia last week, “friendly hacker” Keren Elazari said that co-opting hackers — many of whom are amateurs — to hunt for vulnerabilities “was looked at as a trendy Silicon Valley thing six to eight years ago”.
