South Korean carmaker Hyundai on Wednesday presented the first 7 hydrogen-powered trucks to customers in Switzerland, out of 50 such vehicles scheduled this year to bring zero-emission commercial vehicles to European roads

For long haul, proponents say hydrogen-powered trucks have an advantage over electric rivals as they have a greater range and require less charging times but their uptake and mass production has been slow because they are expensive

However, a McKinsey study in January said that once relative efficiencies of the power sources and lifetime costs of a truck are factored in, green hydrogen could reach cost parity with diesel by 2030

PARITY WITH DIESEL ???

Hyundai has been partnering with Swiss companies to build a value chain covering the production of green hydrogen from hydropower, hydrogen charging stations and the service and maintenance of the trucks

The customers, which include supermarket chain Migros, will be leasing the trucks from Hyundai Hydrogen Mobility HHM to transport goods around the country, backed by the new hydrogen infrastructure

Leases are on a pay-per-use basis that does not require an initial investment

Hyundai plans to put 1,600 trucks on Swiss roads by 2025

Its H2 Xcient trucks have a 190 kW fuel cell stack and seven high-pressure tanks holding 32 kgs of hydrogen, giving them a longer range than comparable vehicles powered by electric batteries on the market now

HHM was set up by Hyundai and Swiss startup H2 energy last year to partner with Hydrospider, a joint venture of H2 Energy, industrial gas maker Linde and Swiss power utility Alpiq

Hyundai plans for production capacity of 2,000 units of Xcient fuel cells per year by 2021 to support its expansion plans as demand for clean transport grows

It views Switzerland as a test case for hydrogen fuel cells in heavy goods transport, said Lee In Cheol, executive vice president and head of the commercial vehicle division at Hyundai Motor Company

“With successful delivery of the first H2 Xcient fuel cell trucks, we proudly announce our plan to expand beyond Europe to North America and China, where we are already making great progress,” he said

In Europe Hyundai has said it will next target Austria, Germany, the Netherlands and Norway

“Energy needed a digital revolution – and we are it”

Greg Jackson, boss of Octopus Energy, says the sector was ripe for an Amazon or Uber-style disruptor, but that his version will also boost the UK’s green revolution

Greg Jackson, chief executive of Octopus Energy, wears the unassuming combination of jeans and trainers one might expect from the founder of a wildly successful startup

There’s also a vast open-plan central London office, easy camaraderie with staff, lots of plants

He has the enthusiasm and world-changing idealism too

With all these markers of a tech unicorn – a deal last month with Tokyo Gas valued it at $2bn (£1.5bn) – it’s easy to forget that Octopus is an energy company

Jackson, 49, says the distinction is increasingly irrelevant

Octopus is a new breed of energy supplier, built on cutting-edge technology and unencumbered by the creaking billing systems and fossil-fuel plants that plague the UK’s “big six”

Set up just five years ago, it has been free to view the energy market as a tech startup would: ripe for disruption

GLOBAL ENERGY CONSUMPTION - A PRIMER

We have hopefully all seen this wonderful diagram from LLNL showing the Flow Diagram of the world’s Energy Consumption in a very useful form full of diagnostic power

So how did we get to here ?

And where are we going from here ?

1. The recent history of Global Energy Consumption

Back in the 1800s the primary use of energy was to generate heat by cutting down trees and vegetation and burning them as fuel - referred to here as “Traditional Biomass”

- this was a defining feature of our World 2.0

2. And then with the advent of the Industrial Revolution fossil fuels like Coal, Oil and Gas became increasingly important

- and they started to define many of the characteristics of our World 3.0

3. Wood-burning Biomass has remained as a significant source of Energy even though its proportion has declined

4. Coal reached as high as 50% of our Energy supply and has continued to grow in absolute terms even though its proportion has shrunk to around 25%

5. Oil took over 40% of the Energy market until the Oil Shock of 1973 started changing our attitudes about the efficiency of its consumption

6. And Gas has been steadily growing its share of the market

@bburnworth Here’s some background

1. Global Vehicle Fleet

2. Natural Demand for new vehicles to support the evolution of the Global Vehicle Fleet

3. BEV Penetration S-Curve that you already alluded to

4. Evolution of BEV supply based on combining Natural Demand and the BEV Penetration S-Curve

5. Evolution of Tesla volume based on 20% Global Market Share of BEVs

LEGACY AUTOMAKERS - 2020 NOVEMBER YTD

As we approach the close of the year, how do the legacy automakers see themselves in 2020 ?

Total global industry volume is down -16% so far, and the two largest players reflect that same reality

Renault is down -22%

Nissan is down nearly -30%

And Mitsubishi is down nearly -39%

Which has brought this unstable alliance down by -28.1% overall

Of course, these numbers only reflect the way the industry likes to present itself to you

And many things about them are not quite as robust as they would have you believe

Let’s touch upon a few :

1. A lot of the volume that VW likes to report does not actually belong to them

2. Instead it belongs to Chinese companies that they only have partial ownership stakes in

3. So when VW actually files its own financial statements, a large part of this volume does not get included

4. On this particular scorecard they are reporting production and not sales

5. This is important for investors to understand because you only earn profits on sales and not on production

6. Any reports of sales numbers from legacy automakers have proven to be unreliable, and are prone to “sales reporting abuses”

VW LOOKS INTO THE VALLEY OF DEATH

The disruptive threats Herbert Diess saw coming for big, incumbent automakers soon after he took over the top job at Volkswagen Group are playing out as predicted -- only faster and in more dramatic fashion

In an interview, Diess said additional cost reductions and a speedier overhaul of the German industrial giant are vital to withstand new rivals with superior financial firepower

He has been reflecting not only on trying to keep pace with Tesla but on the risk that Apple adds another mighty competitor with almost unlimited resources to the automotive arena

“Despite all efforts, we are currently in a rather more difficult situation than in 2018 when I took office," Diess said

"What really has changed -- and what I had not expected to this extent -- is the view of capital markets on our industry”

In the almost 2 1/2 years since Diess told investors VW needed to aim for valuation levels more in line with Apple, Amazon and Google to still be around for another two decades, the gap has only grown

So, today, for the first time in 25 (!) years of Apple, I downgraded. From the 2016 MacBook Pro to my 2013, which I had kept in a drawer...

It was pretty simple to do—Apple Time Machine backups let me do it with one click.

That first tweet captures, in two pictures, how badly Apple has “lost the plot” (to quote @wylieprof). On the right is the Apple MagSafe adapter, from 2013. On the left, what I had “upgraded” to.

Thanks, Apple! I really was nostalgic for worrying about yanking my computer off the table.

Oh and I really appreciated not knowing if my computer was charging. What was great was the little whoop sound you used, so that the speaker before me could be informed I was charging my laptop.

Just published 15,000+ words on security keys. 🔐📱💻

With SIM attacks at their highest, now is a great time to take a closer look at your online security.

Removing SMS from your two-factor auth is a start, but authenticator apps have downsides too...

https://t.co/Dk0MPJHL2V

Just look at these headlines from recent SIM swap and port attacks.

It's all too established for attackers to find ways to socially engineer control of your phone number and start gaining control of your accounts.

I first talk about some general security tips.

Unfortunately not all websites let you remove your phone number from accounts.

You may consider migrating your phone carrier to @googlefi , which requires email account access to do anything (and can be locked down with security keys and even Advanced Protection)

Beyond SMS, I talk about issues that TOTP authenticator apps (the code generators) have as a form of two-factor auth. They're so, so much better than relying on SMS for your second factor but they still have issues like utilizing shared secrets and lacking phishing prevention.

Enter security keys!

Utilizing public key cryptography they don't have any shared secret between the client and the server. They prevent phishing by taking the website domain into account.

Even if you get tricked by a clone phishing website, your key won't.

Two years ago on a weekend, I built a tool to make it easier to evaluate Twitter accounts. Since then 36590 people used it to analyze 55390 different Twitter accounts.

Over the last months @mmkaradeniz and I made a new version. We launched it last night:

@accountanalysis doesn't use machine learning or AI „magic“. Instead of telling users if an account is authentic or not, it helps them to evaluate the accounts themselves.

It visualizes the different features (date, time, type, app, etc.) of Tweets to make them interpretable. /1

@accountanalysis The core concept is still the same, but it looks much better and is easier to operate. Not only for the users, but us developers as well. Enabling us to continuously roll out new features in the future.

Side-by-side screenshots of the old and new version. /2

@accountanalysis Some people had questions what different charts displayed and how they could be interpreted. There are now explanations for all charts, that can be toggled on and off at any time. /3

@accountanalysis The selected/retrieved Tweet count moved to the top to make it clear that not all Tweets of an account are analyzed. 3200 is the API limit by Twitter. It's possible to get more through the Premium API, but I don't think people would pay $100+ for the analysis of one account. /4

(1) Since some people laugh at Cardano project and it's peer review aspect, let me share a story from work for all of you
(2) There is company called Databricks and they open sourced recently a technology called: https://t.co/gpZyKKiMVD . This technology is super important

(3) In BigData delta allows one to perform DELETE and MERGE operations contrary to Hadoop + Hive where this is not possible, seeking through many partitions finding customer data to remove and then rewriting it is not only expensive as an operation but also very dangerous

(4) This promising technology is something that many companies, which have big data turn into as they need to be GDPR compliant.
(5) I was always reading and accepting all details from their website as given and the "truth"

(6) There is however an amazing Principal Developer at our company that found some of the claims from their website as dubious, e.g. ACID claims on such a distributed file system
(7) It turns out this is not the first time this company advertises something that is simply not true

(8) on another occasion this company made untrue claims about Cassandra database and this then became source of disputes e.g by dr. @martinkl - my fave expert in distributed systems
(9) All professional developers also know of course famous Jepsen tests ->

So is Apple's anti-theft security a wonderful boon to users?

Or is it just another evil corporation strengthening it's monopoly power?

I had the misfortune of buying a 2018 Mac Mini on ebay a few days ago. Unfortunately, it had not been wiped, and it's security defaults had never been changed.

This essentially turns it into a very shiny paperweight.

And this is where everybody jumps to blame the victim. "But everybody knows you have to make sure the seller wipes the Mac."

My how the corporate overlords have trained us to be their apologists.

To be clear, I'm a software engineer. Part of my job is supporting Mac users. Where I work, people hold on to their computers for several years generally, and the T2 chips are only a couple of years old, so I hadn't run into this situation at work.

Of course, I'd read about them, but I was confident that whatever condition the computer arrived in, I'd likely be able to deal with it.

Unfortunately I hadn't read up enough to be an expert on their T2 chip and Activation lock.

So when it first appeared in Normandy, the Sherman Firefly and it's meaty 17 pounder represented an ideal combo of reliable chassis, great gun and devastating firepower right?

Ummm...

Truth is a bit more complex. /1
#WW2 #SWW #History

Deliveries of Firefly to units only commenced in April 1944,
just a few weeks before Overlord & left minimal time for familiarisation.

Armoured Regiments mostly utilised Fireflies on a basis of 1 per troop of 4 tanks. /2

Finally each armoured regiment troop had access to integral, meaty, anti-tank firepower capable of dealing serious damage to any German AFV likely to be encountered. /3

The dual purpose 75mm gun was quite capable of laying down a reasonable HE shell or AP round for dealing with Panzer III or IV.

Firefly's 17 Pounder had.... problems with HE, but excelled at tank killing. So Tigers and Panthers would need to be wary. /4

Firefly's design history dated back to March 1943 when the General Staff published "Policy on Tanks" which effectively stated the majority of tanks should have a good HE weapon and...

DODDA GANAPATHI, BENGALURU
#karnatakatemples

Dodda in Kannada means big. Sri Ganesha here is 18 ft tall in height and 16 ft wide. Dodda Ganesha is also known as Shakthi Ganapathi and Satya Ganapathi.

It is said that Kempe Gowda, the founder of Bengaluru, saw a rock here.

The rock had engravings of Ganesha. His sculptors cut the Ganesha murti from that single rock. Later, a shrine was built around the Ganesh murti.

It is believed that Dodda Ganapathi is the protector of Bengaluru. All auspicious events start by praying to Him.

Benne Alankara is the most famous festival here when about 100 kg of butter is coated over Ganapathi every four years and the rich prasad is offered to the worshippers.

Ganesha is also covered in cream colour and is decorated with golden laces and buttons
@GampaSD

The Dodda Ganapathi murti is believed to be still growing in size, especially towards right.

The weavers from old Bengaluru tie a coconut to their looms before starting work. When the work is completed, they break 100 coconuts here along with the one tied on the loom.

Ameda Temple
Ernakulam, Kerala 🚩
#keralatemples

Ameda Ksetram is located in the banks of Vembanad Lake. Temple is very unique and Powerful Sarpa Kavu.
Parashurama did Prathishta here. Vilakku which was lighted by Parasurama is still seen inside the temple.

The oil from this lamp is given to bhakthas for recovering from illness.

Sthala puranam says that, Once, when Parashurama was travelling through Kerala, he reached this place. As it was evening, he stepped into the Lake for Sandhya Vandanam
At that Sapthamathrukkal 👇

(Brahmini, maheshwari, kowmari, vaishnavi, varahi, indirani and chamundi) were travelling there on a tortoise through the water. The tortoise was unable to move, because the Water had made its way for Parashurama. The place where the tortoise became Still came to be known as 👇

Aama Ni Nidayam' ( Aama means tortoise) and later become ‘Ameda’. Parashurama came to know about the journey of Sapthamathrukkal. Thus, he did Prathishta for the Sapthamathrukkal here.
7 forms of Aadi Parashakthi are Sapthamathrukkal. Veerabhadra and Ganesha have Sannidhi here.

The main Garbhagriham in the temple is the Sapthamathrukkal. There are Sannidhi to Nagas, Nagayakshi and Vishnu too. Sarparadhana or snake worship is done here. Naga Panchami is famous here. Those who have Naga Dosham come here and get relieved of their Doshas.
