Published on 11 Jun 2016Forced to flee from his home in Cordoba, Samuel HaNagid made a new name for himself in the kingdom of Granada. He picked his allies carefully and rose to the position of vizier, an unheard of honor for a Jew in a Muslim kingdom. His fame as a poet, a leader, and a patron of Judaic studies spread across the Mediterranean.

While the German Army only fielded 20 A7V tanks during World War 1, they understood the potential of the tank and started working on different designs in the last year of the war. Some designs like the LKII almost got deployed while the Sturmpanzerwagen Oberschlesien or the Krupp-Protze never left the prototype stage.

Metrics are merely a tool. Like any tool they can be misused.
A big problem with depending on metrics is finding things to count that are actually useful measurements of whatever you’re tracking. A lot of bad management decisions can be traced to poorly chosen metrics. As a general rule, just because something can be measured doesn’t automatically mean that measurement will be useful. Tim Harford reviews a recent book on metrics:
Jerry Z Muller’s latest book is 220 pages long, not including the front matter. The average chapter is 10.18 pages long and contains 17.76 endnotes. There are four cover endorsements and the book weighs 421 grammes. These numbers tell us nothing, of course. If you want to understand the strengths and weaknesses of The Tyranny of Metrics you will need to read it — or trust the opinion of someone who has.
Professor Muller’s argument is that we keep forgetting this obvious point. Rather than rely on the informed judgment of people familiar with the situation, we gather meaningless numbers at great cost. We then use them to guide our actions, predictably causing unintended damage.
A famous example is the obsession, during the Vietnam war, with the “body count” metric embraced by US defence secretary Robert McNamara. The more of the enemy you kill, reasoned McNamara, the closer you are to winning. This was always a dubious idea, but the body count quickly became an informal metric for ranking units and handing out promotions, and was therefore often exaggerated. Counting bodies became a risky military objective in itself.
This episode symbolises the mindless, fruitless drive to count things. But it also shows us why metrics are so often used: McNamara was trying to understand and control a distant situation using the skills of a generalist, not a general. Muller shows that metrics are often used as a substitute for relevant experience, by managers with generic rather than specific expertise.
Muller does not claim that metrics are always useless, but that we expect too much from them as a tool of management. For example, if a group of doctors collect and analyse data on clinical outcomes, they are likely to learn something together. If bonuses and promotions are tied to the numbers, the exercise will teach nobody anything and may end up killing patients. Several studies have found evidence of cardiac surgeons refusing to operate on the sickest patients for fear of lowering their reported success rates.

Kalashnikov vs Sturmgewehr!
Forgotten Weapons
Published on 17 Sep 2016http://jamesdjulia.com/item/3024-394/ (MP-44)
http://jamesdjulia.com/item/3020-394/ (Type 56 AK)The German Sturmgewehr and the Soviet Kalashnikov are widely and rightly considered the two most influential and iconic of the modern military rifles. While the German rifle certainly influenced the Soviet design, the two were designed with different intentions and goals. The Sturmgewehr was an attempt to blend the roles of rifle and light machine gun, while the Kalashnikov was intended to blend the roles of rifle and submachine gun – and yet they both reached largely the same practical reality.
Which do you think was the better system?

The appearance of wealth
Victor Davis Hanson on how the wealthy once were eager to appear as distinct from the common herd as possible:
Even in the mostly egalitarian city-states of relatively poor classical Greece, the wealthy were readily identifiable. A man of privilege was easy to spot by his remarkable possession of a horse, the fine quality of his tunic, or by his mastery of Greek syntax and vocabulary.
An anonymous and irascible Athenian author — dubbed “The Old Oligarch” by the nineteenth-century British classicist Gilbert Murray — wrote a bitter diatribe known as “The Constitution of the Athenians.” The harangue, composed in the late fifth century B.C., blasted the liberal politics and culture of Athens. The grouchy elitist complained that poor people in Athens don’t get out of the way of rich people. He was angry that only in radically democratic imperial Athens was it hard to calibrate a man by his mere appearance: “You would often hit an Athenian citizen by mistake on the assumption that he was a slave. For the people there are no better dressed than the slaves and metics, nor are they any more handsome.”
The Old Oligarch’s essay reveals an ancient truth about privilege and status. Throughout history, the elite in most of the Western world were easy to distinguish. Visible class distinctions characterized ancient Rome, Renaissance Florence, the Paris of the nineteenth century, and the major cities of twentieth century America.
A variety of recent social trends and revolutionary economic breakthroughs have blurred the line separating the elite from the masses.
First, the cultural revolution of the 1960s made it cool for everyone to dress sloppily and to talk with slang and profanity. Levis, T-shirts, and sneakers became the hip American uniform, a way of superficially equalizing the unequal. Contrived informality radiated the veneer of class solidarity. Multimillionaires like Bruce Springsteen and Bono appear indistinguishable from welders on the street.
The locus classicus is perhaps Facebook owner Mark Zuckerberg, who wears T-shirts, jeans, and flip flops to work. His reported wealth of $71 billion makes him the world’s fifth-richest man. The median net worth of Americans is about $45,000. Zuckerberg is worth more than the collective wealth of about 1.5 million Americans — or about all the household wealth in Philadelphia put together. And yet, he looks perfectly ordinary. When I walk the Stanford campus — where many of the world’s wealthiest send their children — the son of a Silicon Valley billionaire looks no different from a machinist’s daughter on full support from Akron.
Second, technology has done its part to dilute superficial class distinctions. The nineteenth-century gap between a rich man in his fine carriage — with footman and driver — and someone walking three miles to work has disappeared. The driving experience between a $20,000 Kia bought on credit with $1,000 down and a $80,0000 Mercedes paid in cash is mostly reduced to the superficial logo on the hood and trunk. An alien from Mars could not easily distinguish, at least by sight, between the two cars. Even after a ten-minute ride, an alien might be puzzled: What exactly did that extra $60,000 buy?

Published on 12 Aug 2016In the 25th Tank Chat David Fletcher explores the First World War Mark VIII tank. The Mark VIII tank, also known as The International was a joint project between the British and American forces, following their entry into the war. Once the designs had been refined massive orders were placed in 1918 and then swiftly cancelled with the end of the war. In the end six Mark VIII tanks were built for Britain of which The Tank Museum’s is the sole surviving example.
