Published 7 Sep 2018

Another episode in the Tank Chats Funnies Specials, with David Fletcher looking at the weird and wonderful vehicles of 79th Armoured Division led by Major General Percy Hobart, known as “Hobart’s Funnies”.

The Sherman DD, or Duplex Drive, was a term applied to Sherman tanks modified for amphibious operations. DD tanks were used by American, British and Canadian forces in WW2 on D-Day, 6 June 1944; by the Americans again in the south of France and by the Americans and British during the Rhine crossing.

More frequent car fires, an unintended consequence of wider adoption of electric vehicles

Filed under: Technology — Tags: , , — Nicholas @ 05:00

In Quadrant, Tim Blair recounts the story of a friend crossing the Sydney Harbour Bridge only to find his vehicle was on fire:

A BMW on fire in Portland, Oregon.

Most of us manage to scrape through life with no such flame-related driving incidents. Future motorists, however, may find themselves more frequently enjoying the occasional car-b-que. That’s because electric cars — the things Labor ruinously attempted to force upon us as part of their spectacular 2019 election campaign disaster — seem to be impressively prone to burning.

Now, an ordinary car fire is not really that big a deal. Catch it early enough and it can be quickly dealt with. But a fire involving an electric car is a whole different matter. Those things are like four-wheeled infinity candles.

In the manner of all the money given to its manufacturer by various governments, an electric Tesla recently torched itself in Austria. The Tesla’s fifty-seven-year-old driver had slid off the road and struck a tree, prompting a fire emergency.

In ordinary car blaze cases, a single fire engine or even a personal fire extinguisher is sufficient to deal with the problem. Electric cars, or EVs, demand slightly more attention when combustion occurs. Here’s an online news account:

    In order to put out the fire, the street had to be closed and fire authorities had to bring in a container user to cool the vehicle.

    Some 11,000 litres of water are needed to finally extinguish a burning Tesla but an average fire engine only carries around 2,000 litres of water.

    The container used is said to be suitable for all common electric vehicles. It measures 6.8 metres long, 2.4 metres wide and 1.5 metres high, it is (obviously) waterproof and weighs three tons.

Moreover, “fire brigade spokesman Peter Hölzl warned that the car could still catch fire for up to three days after the initial fire”.

I’ve owned one or two cars that were sensibly equipped with fire extinguishers. Future motorists may wish to tow around a lake, just in case their earth-friendly electric cars decide to go the full kaboom.

Early flight started as a utopian dream but quickly became the military’s top priority: first as reconnaissance vehicles, and then as weapons in their own right. After WW1, the threat of German aircraft led to the Treaty of Versailles banning Germany from having an airforce at all. But the Germans also found a loophole: rockets didn’t count as an airforce. Enter Werner Von Braun & the V-2 rockets.

A Tale of Swords and Gunpowder – Weapons in Ancient China l HISTORY OF CHINA

IT’S HISTORY
Published 12 Aug 2015

Dao, Gun, Jian and Quiang are the four main traditional fighting weapons of China. Even though, the Chinese had already invented gunpowder by the end of the tenth century. So besides of having an arsenal of swords, spears, sabres, crossbows and bow and arrows, the Chinese military could also choose from cannons, rockets, mines and even handheld firearms. Still, close combat would remain the favoured means of battle for a long time. All about the history of Chinas weaponry now on IT’S HISTORY!

Notepad++ release 7.8.1, also known as the “Free Uyghur” edition, draws unfriendly Chinese attention

Filed under: China, Liberty, Religion, Technology — Tags: , , — Nicholas @ 03:00

I’ve been using Notepad++ as one of my text editor options for a long time. It’s a very useful tool, and I heartily commend it to anyone needing a Windows text editor that can do a lot more than just edit text. I hadn’t downloaded the most recent version, so I was unaware that the developer was under attack from Chinese government supporters for his explicit designation of version 7.8.1 as the Free Uyghur edition:

On Tuesday, Don HO, the developer of Notepad++, a free GPL source code editor and notepad application for Microsoft Windows, released version 7.8.1, prompting a social media firestorm and a distributed denial of service attack.

Notepad++ v7.8.1 was designated “the Free Uyghur edition,” in reference to the predominantly Muslim ethnic group in western China that faces ongoing human rights violations and persecution at the hands of Beijing.

“The site notepad-plus-plus.org has suffered DDoS attack from 1230 to 1330 Paris time,” HO said in an email to The Register. “I saw the [reduced] amount of visitors via Google analytics then the support of my host confirmed the attack. The DDoS attack has been stopped by an anti-DDoS service provided by our host [Cloudflare].”

Previous politically-themed Notepad++ releases have focused on Tiananmen Square and the terrorist attack on French satirical publication Charlie Hebdo.

A post on the project’s website explains HO’s decision to criticize the Chinese government, something companies with business interests in China generally try not to do for fear of retribution.

From the Notepad++ website:

Human rights in China is always a hotly contested topic. Since 2017, numerous reports have emerged of the Uyghur people being detained in extrajudicial “re-education camps”, subjected to political indoctrination, and sometimes even torture. 2018 estimates place the number of detainees in the hundreds of thousands.

The Uyghurs are not ethnically Chinese but live in China’s so-called autonomous Xinjiang region. The region’s name suggests the Uyghurs have autonomy and self-governance. But similarly to Tibet, Xinjiang is a tightly controlled region of China. After the recent Xinjiang conflict, Beijing has recast the Uyghur ethnic group as a terrorist collective. This has allowed Beijing to justify its transformation of Xinjiang into a surveillance state. There has also been a marked rise of Islamophobia across China.

At least 120,000 members of Kashgar’s Muslim Uyghur minority have been detained in Xinjiang’s re-education camps which aim to change the political thinking of detainees, their identities, and their religious beliefs. Reports from the World Uyghur Congress submitted to the United Nations in July 2018 suggest that 1 million Uyghurs are currently being held in the re-education camps.

A mathematical revolution in late medieval English ship design and construction

Filed under: Britain, History, Technology, Woodworking — Tags: , , , , — Nicholas @ 03:00

In the latest installment of Anton Howes’ newsletter on the Age of Invention, he discusses how geometry and mathematics helped transform late Medieval English shipbuilding:

An English ship of a slightly later period: this is a replica of the Susan Constant at the Jamestown Settlement in Virginia. The original ship was built sometime before 1607 and rented by the Virginia Company of London to transport the original settlers to Jamestown.
Photo by Nicholas Russon, March 2004.

Since about 1500, an Italian and Portuguese method of making ships had come into ever wider use in northern Europe. This was to construct the ship’s skeleton first, and then lay the planking around it. This contrasted with the older “clinker” method, by which the planks were laid from the keel upwards, with each plank slightly overlapping the one below – the rest of the skeleton was filled in later to strengthen it. The new “carvel” method, instead of having overlapping planks, allowed for a smooth hull. But it also required more planning.

The master shipwright had to first design full-sized templates, or frames, which were placed along the keel to determine the width and height of the hull, like cross-sections up and down the length of the ship. To the edges of these frames were then fixed ribbands — long, pliable boards running down the ship’s length. Altogether, the frames and ribbands formed a temporary, basket-like structure, to guide the moulding of the ship’s permanent hull around it.

But calculating the size of the frames at each point was tricky. After the placement of the first few, which might be pre-specified in size, the next ones along were typically determined according to the curve of the ribbands. Calculation was certainly involved, but it took place in the form or marking and adjusting the wood itself. Design and construction both took place in the shipyard, and through the medium of wood.

What Matthew Baker did in the 1570s was to take the design process out of the shipyard, and onto paper. He drew his ships, to scale. And by using pen and paper, with geometry to make such drawings possible, he opened up grand new possibilities for design. His process allowed him to jot down the latest innovations from the Mediterranean, to speculate about the designs of Noah’s ark and the ships of the ancient world, and to cheaply conduct his own experiments. He drew out new designs for frames, using geometry to work out how any variation would affect the overall shape of the hull, as well as its weight and carrying capacity – all at the cost of only time, ink, and paper, and avoiding the huge potential waste of conducting experiments at full scale in wood. His process allowed him to innovate more easily, and even to design new measuring instruments.

2 years ago (edited)
Hey all, I hope that you like this video. Small correction from my side at 05:00 – It was reprinted in 1980 not 1918. I misspoke. Obviously.

This video was actually planned for the end of September but since I had the script already, I decided to publish it now. As mentioned to my Patreons some days ago, I have a few unexpected home visists to make. The first set was last week and after returning two days ago, I flew off to yesterday for another week abroad. As such it made sense to get such a familiar topic out now since otherwise, there would be nothing.

It should be mentioned that I did not find the “original” study Wald responded to. Either it got lost, or it was never published. Perhaps Wald saw them work on it, saw the errors and published his paper leading the other group to abandon their project. However, there is also a slight chance that over the years parts of the story were exaggerated. Wald certainly published his papers (you’ll easily find it on the internet) and was given the credit for helping US designers — but what of that inital research group? What were their conclusions, their recommendations beyond what is usually linked to Wald? Without their study, no one seems to know.

Dreyse Model 1835 Needlefire Breechloading Pistol

Johann Nicolaus Dreyse, later promoted to the aristocracy as Nicolaus von Dreyse, designed the first mainstream military breechloading rifle. His rifle was adopted by Prussia and changed military history, but this was not his only work. Dreyse also endeavored to sell guns commercially, both rifles and handguns. This is an example of one of his first, the Model 1835. It is a single shot breechloader, with the chamber consisting of a rotating tumbler. The firing mechanism is identical in concept to that of his Model 1841 rifle, just scaled down for the smaller pistol. The piece uses a power charge of just 6 grains, but its breechloading action was quite advanced for the 1830s!
