Technological attempts to preserve Middle Eastern antiquities

Ars Technica calls them the digital “Monuments Men”:

The student who proclaimed this idea is part of a new generation of cultural guardians who are starting to make a name for themselves around the world as the digital “Monuments Men.” Originally the Monuments Men were a group of people, most of them with a cultural studies background, who joined a special branch of the US Army for one reason only: to save and retrieve stolen art from the Nazis. The goal of the digital Monuments Men today is no less important: they want to save global culture from destruction.

As a member of CyArk, Davison is providing tech and knowledge to those on-the-ground experts. The non-profit organisation has dedicated itself to digitising the UNESCO World Heritage sites. Within five years it plans to scan 500 cultural sites in order to transform them into digital 3D models. So far that has worked out quite well — at least for easily accessible examples such as the Brandenburg Gate in Germany or ancient Corinth in Greece. In crisis areas, failed states, and autocracies this task is a lot harder.

The CyArk organisation uses just about every tool that high-technology has to offer: 3D scanners, drones of every size, 360-degree cameras, 3D printers, smart software, and virtual reality systems. It seems as if the idea is certainly causing some serious stir: over 250 ambassadors, government officials, experts, and activists from 35 countries attended CyArk’s annual conference in Berlin this year.

In countries such as Syria, Iraq, or Libya thousands are fighting against the ongoing destruction of historical sites. They are working against time, against the environment, against natural catastrophes, and most of all against war. Since ISIS (ISIL, Daesh) started its mass destruction of historical and religious sites, the threat has become bigger. Not a week goes by without a new YouTube video popping up that shows monuments being blown into bits and pieces or destroyed by hammer-swinging terrorists.

Davison and his students are supposed to respond to ISIS with a secret offensive—and they’ve got the support of industrial and political elites.

There are other groups with slightly different approaches to preserving what can be preserved even if only through crowdsourced images to help create 3D models:

Other groups of cultural guardian activists rely more on Internet communities than secret data-smuggling. “Project Mosul,” for example, named after the city of Mosul in Iraq, uses Internet crowdsourcing, letting users upload their photos directly. Project Mosul also uses pictures of places they find on Flickr. The more photos they find, the easier it gets for them to create a 3D model of an endangered site.

If critical information is missing, members of the community reconstruct the rest. Scientifically this isn’t 100 percent accurate, but it is better than nothing. “I lived in Jordan for eleven years, and the destruction from Syria came so close, I had to do something,” says cofounder Matthew Vincent. Now his platform processes pictures from all around the world, not only Mosul.

In another interesting development, some companies are upgrading these 3D models into full virtual reality environments. David Fürsterwalder just founded his startup, realities.io — a company that specialises in “virtual tourism.” “We need to bring those places back to life instead of just preserving them,” he explains. Fürsterwalder is convinced that we stand on the brink of a VR revolution: “This is not only something for the museum. It will bring virtual journeys to every living room.”

Does Teddy Bridgewater hold the ball too long?

Filed under: Football — Tags: , , , , — Nicholas @ 03:00

Over at Vikings Territory, Brett Anderson endangers his health, eyesight, and even his sanity by exhaustively tracking, timing, and analyzing every throw by Teddy Bridgewater in last week’s game against the Green Bay Packers. A common knock on Bridgewater is that he’s holding the ball too long and therefore missing pass opportunities and making himself more vulnerable to being sacked. It’s a long article, but you can skip right to the end to get the facts distilled:

What The Film Shows

It became clear pretty quickly that plays with larger TBH [time ball held] had a lot happening completely out of Bridgewater’s control. There were only a couple of plays where it clearly looked like Bridgewater held the ball too long while there were options downfield to target or that he hesitated to pull the trigger on guys that were open. And consistently, there were three issues I kept noticing.

  1. Receiver route depth – The Vikings receivers run a ton of late developing routes. I don’t have any numbers to back that up – we’re talking strictly film review now. But on plays ran out of the shotgun with 5-step drops or plays with even longer 7-step drops, by the time Bridgewater is being pressured (which happens about every 2 of 3 plays), his receivers have not finished their routes. And I know that just because they haven’t finished the route doesn’t mean Bridgewater can’t anticipate where they are going to be but… We’re talking not really even close to finishing their routes. It seems that a lot of the Vikings play designs consist of everybody running deep fade routes to create room underneath for someone on a short dig or to check down to a running back in the flat. So, if this player underneath is for any reason covered (or if the Vikings find themselves in long down and distance situations where an underneath route isn’t going to cut it, which… surprise, happens quite often), Bridgewater’s other receiver options are midway through their route 20 yards downfield. What’s worse? Not only are these routes taking forever to develop and typically only materializing once Bridgewater has been sacked or scampered away to save himself, but also…
  2. Receiver coverage – The Vikings receivers are typically not open. It was pretty striking how often on plays with higher TBH receivers have very little separation. (Make sure to take a look through the frame stills linked in the data table above. I tried to make sure I provided a capture for plays with higher TBH or plays that resulted in a negative outcome. Red circles obviously indicate receivers who are not open while yellow typically indicates receivers who are.) The Packers consistently had 7 defenders in coverage resulting in multiple occasions where multiple receivers are double teamed with safety help over the top. But even in plays with one on one coverage, the Vikings receivers are still having a difficult time finding space. So now, we have a situation with Bridgewater where we have these deep drops where not only are receivers not finished with their deep routes but they are also blanket covered. And why are teams able to drop so many players into coverage creating risky situations for a quarterback who is consistently risk adverse? Because…
  3. Poor offensive line play – The Vikings offensive line is not good. And it may be worse than you think. It’s no secret by this point that the Vikings offensive line had one of its worst showings of the year against the Packers. More often than not, simply by rushing four defenders, Green Bay was able to get pressure on Bridgewater within 2-3 seconds. This is a quick sack time. And more often than not, Bridgewater is having to evade this pressure by any means necessary to either give his receivers time to finish their routes or give them time to get open. (Or more frequently – both.) As a result of this, what we saw on multiple occasions against the Packers is Bridgewater being pressured quickly, him scrambling from the pocket and dancing around while stiff-arming a defender once or twice and ultimately throwing the ball out of bounds or taking a sack. Are you starting to see what the problem here?

Conclusion

Bridgewater is not holding the ball for a length of time that should reflect poorly on his play. The data shows that Bridgewater is about average when looking just strictly at the numbers. The tape shows a quarterback who really doesn’t have a lot of options other than holding on to the ball. When Bridgewater is presented with a quick 1- or 3-step drop and his receivers run routes with lengths complementary to the length of his drop, it typically results in Bridgewater finding a relatively open receiver, making a quick decision and getting the ball there accurately. When Bridgewater is faced with longer developing plays behind an offensive line that’s a sieve and receivers who are running lengthy routes while closely covered, he tries to make a play himself. Sure, there were a couple of plays during the Packers game where it may have been a better decision for Bridgewater to take a sack when initially pressured and saving the yards he lost by scrambling backwards. However, it’s difficult to chastise him for trying to create plays when they aren’t there when it doesn’t work and applauding him when his evasiveness, deadly stiff arm and surprisingly effective spin move result in a big play.

Bridgewater has been far from perfect this season. But after this extensive exercise, I can comfortably say that the amount of time Bridgewater is holding on to the ball should not negatively reflect on his performance considering the above mentioned external factors.

President Nero

Filed under: History, Humour, Politics — Tags: , , — Nicholas @ 02:00

Last month, David Warren wrote about the Emperor Nero as if he were a modern American president:

While Rome burned, it is said, the Emperor Nero golfed, partied, and selfied. This, anyway, is my updated account. In an earlier version, he played his fiddle. The fire, which broke out in the evening of 18th July, 64 anno Domini (or 817, ab urbe condita), continued for a week, levelling ten of pagan Rome’s fourteen districts, and leaving at least half a million homeless. I gather it started in the merchant quarter, where fires usually started, back then. There were lots of merchants; there were lots of warehouse fires. And this despite numerous municipal regulations.

Read your Tacitus, however, and you will see that this rumour has been corrected. In fact, Nero rushed back to Rome from his palace at Antium (just outside the Beltway), took charge of the fire-fighting operation from the first night, opened public buildings and his own gardens to shelter the dispossessed, and made immediate arrangements to import huge quantities of grain into the city, for distribution free or at nominal cost. Criticisms of his Department of Homeland Security were feverish and unfair.

There is another problem with this rumour. The violin was not invented for another fifteen hundred years. Those still circulating the story should say he was playing on his cythera, instead. Nero was an enthusiastic and accomplished amateur musician; perhaps some people resented it. He was a man of culture; an Ivy League guy. But he was also an accomplished politician, and nobody’s fool.

Rumours that he set this fire himself are about as likely as rumours that George Bush started Hurricane Katrina. It would not have been in the chief executive’s interest to do so, in either case. For Nero was already sinking in the polls — curiously not because he’d ascended to office by having his mother kill his uncle, then killing his mother in turn; or many similar instances of hardball. Politics was politics then as now; success is to the ruthless. No, Nero was unpopular thanks to his growing reputation for ineffectuality. His failure to stop the fire hurt him in the same way as Bush’s failure to stop the hurricane.

After consulting with a few focus groups, Nero decided upon a scapegoat. He chose the Christians. He accused them of complicity in setting the fire, and his subsequent persecution of them — which included the martyrdoms of Saint Peter and Saint Paul — probably improved his popularity rating, at least slightly. From what I can make out, the early Christians were not well liked. People thought they were spooky and weird.

QotD: German women

Filed under: Europe, Germany, History, Humour, Quotations — Tags: , , — Nicholas @ 01:00

If anything change the German character, it will be the German woman. She herself is changing rapidly — advancing, as we call it. Ten years ago no German woman caring for her reputation, hoping for a husband, would have dared to ride a bicycle: to-day they spin about the country in their thousands. The old folks shake their heads at them; but the young men, I notice, overtake them and ride beside them. Not long ago it was considered unwomanly in Germany for a lady to be able to do the outside edge. Her proper skating attitude was thought to be that of clinging limpness to some male relative. Now she practises eights in a corner by herself, until some young man comes along to help her. She plays tennis, and, from a point of safety, I have even noticed her driving a dog-cart.

Brilliantly educated she always has been. At eighteen she speaks two or three languages, and has forgotten more than the average Englishwoman has ever read. Hitherto, this education has been utterly useless to her. On marriage she has retired into the kitchen, and made haste to clear her brain of everything else, in order to leave room for bad cooking. But suppose it begins to dawn upon her that a woman need not sacrifice her whole existence to household drudgery any more than a man need make himself nothing else than a business machine. Suppose she develop an ambition to take part in the social and national life. Then the influence of such a partner, healthy in body and therefore vigorous in mind, is bound to be both lasting and far-reaching.

For it must be borne in mind that the German man is exceptionally sentimental, and most easily influenced by his women folk. It is said of him, he is the best of lovers, the worst of husbands. This has been the woman’s fault. Once married, the German woman has done more than put romance behind her; she has taken a carpet-beater and driven it out of the house. As a girl, she never understood dressing; as a wife, she takes off such clothes even as she had, and proceeds to wrap herself up in any odd articles she may happen to find about the house; at all events, this is the impression she produces. The figure that might often be that of a Juno, the complexion that would sometimes do credit to a healthy angel, she proceeds of malice and intent to spoil. She sells her birth-right of admiration and devotion for a mess of sweets. Every afternoon you may see her at the café, loading herself with rich cream-covered cakes, washed down by copious draughts of chocolate. In a short time she becomes fat, pasty, placid, and utterly uninteresting.

When the German woman gives up her afternoon coffee and her evening beer, takes sufficient exercise to retain her shape, and continues to read after marriage something else than the cookery-book, the German Government will find it has a new and unknown force to deal with. And everywhere throughout Germany one is confronted by unmistakable signs that the old German Frauen are giving place to the newer Damen.
