After the Russian defeats on the Eastern Front, Warsaw falls. The first time in over 100 years a foreign power occupies the city. The German onslaught in the East seems to be unstoppable. Also on the Western Front the Germans are causing havoc with the new Fokker-Eindecker planes which start the so called Fokker Scourge. The British pilots even start to call their airplanes Fokker-Fodder. At the same time, the battle in Gallipoli continues with ever more troops landing while neither the Ottomans nor the ANZAC troops can gain any advantage.

Warsaw Falls – The Fokker Scourge Begins I THE GREAT WAR Week 54
Looking back at April’s 7.8 earthquake in Nepal
At Ars Technica, Scott K. Johnson what has been learned about the devastating earthquake that struck Nepal earlier this year:
The mighty Himalayas have been driven up into the sky by the collision of Eurasia and India, which has migrated north like a tectonic rocket over the last 100 million years. The Indian plate is being crammed beneath the crumpled Himalayan rocks along a dangerous fault that ramps downward to the north.
Lots of GPS sensors and seismometers have been deployed in the area to help seismologists study earthquakes here. Combined with precise satellite measurements of surface elevation changes, researchers have the means to work out where the movement on the fault must have occurred.
The earthquake began about 80 kilometers northwest of Kathmandu and about 15 kilometers beneath the surface. Geologists like to talk about faults “unzipping,” which is a helpful way to visualize what’s going on. A small patch of the fault plane slips, and then expands outward along the fault. In this case, the patch unzipped about 140 kilometers to the east in under a minute, traveling horizontally along the fault plane. Within that patch, the rocks slipped as much as six meters past each other.
Although it’s the seismic energy released by that sudden motion that causes the damage, the surface changes are still eye-catching — some of the GPS stations ended up two meters south of where they had been before the earthquake.
As for that seismic shaking, the pattern of building damage in Kathmandu was partly the result of the geology beneath the city. It sits on a roughly 500-meter-thick stack of lake and river sediment filling a bedrock bowl. The reverberation of seismic waves in that bowl produced a resonance, building stronger waves with a period of 4 to 5 seconds. While fewer homes were actually damaged than expected, taller buildings — which can sway at about that same frequency — didn’t fare as well. (A similar thing happened in the 1985 Mexico City earthquake, when buildings between 6 and 15 stories bore the brunt.)
Hacking a Tesla Model S
At The Register, John Leyden talks about the recent revelation that the Tesla Model S has known hacking vulnerabilities:
Security researchers have uncovered six fresh vulnerabilities with the Tesla S.
Kevin Mahaffey, CTO of mobile security firm Lookout, and Cloudflare’s principal security researcher Marc Rogers, discovered the flaws after physically examining a vehicle before working with Elon Musk’s firm to resolve security bugs in the electric automobile.
The vulnerabilities allowed the researchers to gain root (administrator) access to the Model S infotainment systems.
With access to these systems, they were able to remotely lock and unlock the car, control the radio and screens, display any content on the screens (changing map displays and the speedometer), open and close the trunk/boot, and turn off the car systems.
When turning off the car systems, Mahaffey and Rogers discovered that, if the car was below five miles per hour (8km/hr) or idling they were able to apply the emergency hand brake, a minor issue in practice.
If the car was going at any speed the technique could be used to cut power to the car while still allowing the driver to safely brake and steer. Consumer’s safety was still preserved even in cases, like the hand-brake issue, where the system ran foul of bugs.
Despite uncovering half a dozen security bugs the two researcher nonetheless came away impressed by Tesla’s infosec policies and procedures as well as its fail-safe engineering approach.
“Tesla takes a software-first approach to its cars, so it’s no surprise that it has key security features in place that minimised and contained the risk of the discovered vulnerabilities,” the researchers explain.
Canada to hold longest election campaign in living memory
For those of you not familiar with Canadian politics — and unless you’re a Canadian why would you be? — the longest election campaign since the 19th century kicked off on Sunday, as Prime Minister Stephen Harper went to the Governor General’s office to request that parliament be dissolved. This is going to be a long, long, gruelling political death-march. Eleven whole weeks of politicians bloviating, TV talking heads pretending to interpret every twitch in the polls, political candidates of all shades from light pink to deepest red popping up at every possible gathering of more than three people to beg for votes … it’s going to be awful.
Over at Gods of the Copybook Headings, Richard Anderson provides the early scorecard on the leaders of the major federal parties:
In his infinite cruelty the PM has imposed upon the Canadian people, who never did him any harm, a formal eleven week election campaign. The longest since 1872. Much of Canada still wasn’t part of Canada in 1872. After eleven weeks of politicking those regions might be thinking of leaving. British Columbia we will miss you dearly. Newfoundland much the same.
Lest we complain the status quo remains. As Ronald Reagan once observed status quo is Latin for the mess we’re in. Our particular mess has a dull and worthy quality befitting our national character. This brings us to the vital question: What is Election 2015 about?
Is it about Justin Trudeau’s fitness to rule the nation? No, because nobody in their right mind thinks the Dauphin is fit to rule. He’s a front man for those shrewder than himself. If current polls are to be trusted it appears that Canadians are not keen on a Gerald Butts government.
Perhaps it’s about Thomas Mulcair and his ability to lead. Can you, the good and sensible people of our fair Dominion, imagine yet another Quebec lawyer as ruler of all the Canadas? And if you can hold that mental picture, while still holding your lunch, have you thought carefully about who is part of Team Mulcair? However astute and moderate a PM Tommy might turn out to be he will need build a cabinet. Have you seen the timbers of the NDP caucus lately? […]
Canadians, it is understood, are creatures of habit. We likes what we likes. There is a tendency for the electorate to plunk for the bank manager candidate. The safe pair of hands who won’t screw things up too much. As a people we generally avoid Messiahs or Rabble Rousers. It offends our sense of proportion. We want someone clever enough to deal with basic problems but sensible enough not to wreck the place between elections. In our long national history we have deviated from this common sense approach just once. Way back in 1968 we took a wild and daring risk. The result was fifteen years of Pierre Trudeau.
Bill Davis, perhaps the most quintessential of Ontario politicians, famously attributed his success to a simple formula: Bland works. Stephen Harper is our bland candidate. Beneath the bad hair cut the enormous brain continues to plot. It plotted the Canadian Right out of the political wilderness. It plotted Canada away from the disaster of an Liberal-NDP-Bloc Coalition. Nimbly has it darted us through the shoals of the world economy. He ain’t great but he’s better than what else is on offer.
This October my fellow Canadians let us be boring. Let us be sensible. Let us be bland. It’s what we do best and why, whatever happens over the next eleven weeks, Stephen Harper will probably still be running the joint for years to come. All hail the new Mackenzie King.
QotD: Kids these days
Sometimes I despair for the kids these days, I really do.
I didn’t expect to feel this way at the tender age of 42. I was supposed to find them puzzling, with their Snapchatting and their Venmo and never looking up from their phones. I was supposed to think they were having too much sex or doing too many drugs and not listening to their wiser elders, gosh darn it. I was supposed to grouse that young people are always getting themselves into trouble.
Instead I’m worried that they aren’t getting themselves into enough trouble. They seem so fragile. They can’t read Ovid without a trigger warning and a pair of latex gloves, or go off to college without calling their parents to check in. Did no one ever take them aside and explain that college is for abandoning your parents, leaving them to worry about what you are doing with their money while you forget to call them for a month at a time ? There is something truly terrifying about a generation of younger people that craves more adult intervention into their lives. Yet, that’s what everyone from teachers to employers reports: a rising number of kids who seek to be tethered to their parents, and don’t seem to know what to do unless Mom or Dad is hovering nearby.
I know, I know. People have been worrying about The Kids These Days since time immemorial. And yet, older people I talk to — ones old enough to remember seeing the low-speed, low-stakes train wreck that was my own generation hurtling through college and into the workforce — confirm my impression that This Time Really Is Different. The upper stratum of the Trophy Kids really are going into college expecting to live in a sort of Nerf universe where nothing ever really hurts, and there’s always an adult to pick them up and put them back on track. And they’re coming out into the workforce expecting the same sort of personal concierge service from a world that, as I was myself dismayed to find 20 years ago, really doesn’t have time to care how they feel.
Not that I blame the kids for this. Their parents are the ones who did it to them, hovering over them every spare minute — and in those rare moments when they have some time off from the endless commute between soccer practice and enrichment activities, calling the cops on anyone who leaves an 11-year-old outside to play basketball for an hour, so that their parents will have to hover too.
