Don't know if you've taken the exam, but I passed ICND1 on my second attempt. If you can't subnet don't show up. I had 3 sims on my first and only two sims on my second. The test format is a killer because you can't go back to a previous question. 804 is currently the passing score.

Anyone reading Left of Boom?
An "advance copy" of Tom Rick's The Generals was in the giveaway book box at work. I don't like Ricks but I knew the book had some useful information in it for a class I'm teaching next semester so I picked it up. Based on what I've read so far I grudgingly admit that Ricks is a good writer and The Generals is (at least) a decent book.

Climbing the North Face of Everest. This is written of the same time of the popular "Into Thin Air" . I am looking to see what the conditions were like on the North Face of Everest. I have just started, and much is being said of the discovery of George Lee Mallory, a lost climber of the late 20's. if you look at what they had for protection from the cold, I don't know how any survived at all.Mallory was found face down in scree, just off the climbing path. The rope around his waist was hemp, and was broken several feet from his body. His fall resulted in two compound fractures of his right lower leg. His left foot was across the right as if protecting the fracture. While the fracture, in an of itself, was enough to make him nonrecoverable, there was a fracture in the frontal bone of his head, about the size of a golf ball. Speculation is that the skull fracture may have been caused by his ice axe.
If you see what their climbing was, compared to today, I am surprised more were not killed by hypothermia, and exposure.

I thought the overall thesis of the book - that a lack of accountability for operational failure at the top is a key factor in the inability of the American military to win wars - was convincing. However, thought his scholarship and history was atrocious. I don't think Ricks' academic rigor would hold up in any reputable history department.
I missed it, but the discovery of Mallory is interesting as the judgement was that he made it to the summit. On what part of the climb was his body found?

The information proving Mallory Summited Mt. Everest, before Hilary/Norgy, is still unanswered. Mallory's remains were found rather well intact:
. The camera he carried with him held absolutely no answers. His climbing partner, Sandy Irvine, has yet to be found. Mallory's cause of death was from a hole in the frontal skull bone, perhaps from his ice axe. They were last seen alive as they made for the summit before weather moved in, blocking them from view. This means weather was not on their side, and the final push was late in the day. Also of note, Mallory's Northern approach route is technically more difficult than the Southern, Hilary's, route.
When last seen, reports claim that the two climbers were at the base of the first of two difficult "steps", with the "pyramid" of Everest above that. There is great danger in late in the day summits. as dangerous as the push for the top is, it is in descent that many of the mishaps take place. At that altitude for very long, swelling of the brain, "Altitude sickness" will make climbers stark raving mad, with a complete break with the real world. Seasoned climbers have simply stepped off into space, not knowing where they really are. Some have become so combative, that rescue attempts have been impossible.
There is a "Death Zone" that climbers enter while climbing Everest, or any peak above 26,000'. Once in that zone, even with supplemental oxygen, the body starts to die, and there is no way to stop it without a pressurized suit. The longer you spend in the Death Zone, the greater the risk of death. At lower altitudes, the body will slowly adjust to the lower percentage of oxygen. Red Blood cell production increases, and allows more oxygen to be carried to the bodies tissues and organs. That ability peaks just below 26,000'. Above that all cells begin to die, and it is just a matter of time before you simply keel over and die.
I'd like to think Mallory did summit. My head, and what I know of altitude and climbing, I do not believe Mallory and Irvine made it to the summit.

In general terms, even with aid and civi climbing the downclimb is always an area to watch as you've completed the climb and are feeling pretty good, so tend to switch off. I'm thinking it may have been 'summit fever' that brought Mallory and Irvine undone as it was late in the day and they chose to roll the dice.

I think you are spot on. Mallory and his fellow Alpine Climbers knew nothing about dangers of climbing much beyond what they physically saw. They were just breaking into using supplimental oxygen, and producing delivery systems that would not freeze up and fail, was a conatant concern. Mallory was very involved with oxygen delivery systems, but they never carried enough.
Regarding the dangers of descent, is the fear, and vertigo producing one feels comes from looking down from altitude. Climbers are more fatigued, and loose focus rapidly. Even today, there are lines secured to the climbing surface. Sherpas set new lines and ladders every year. Climbers hook on to the securing line, preventing falling. When secured to these lines, you may fall a short distance, but you are still secured to the safety line. On descent, climbers have been seen failing to secure themselves to the safety line. Hooking and unhooking to the safety line is a very frequent requirement. You have to do this as you meet other climbers who are still waiting to summit. You have to unhook/hook at points where the safety line is secured to the climbing surface.
All that said, even today, with safety lines professionally set, climbers still fall from the mountian face. At the time of Mallory, and Irvine, climbers were roped together for safety. Ideally one climber would establish a safe stable position, then aid the other climber with their connecting rope. The thought was, that the fall one would experience was limited to the length of rope connecting the two climbers. The rope around Mallory's waist was broken.

I agree, I think summit fever claimed two more victims that day. I also think they made it, but darkness, fatigue, and hypoxia did them in. There are a few scenarios to explain the broken connection rope, broken legs, and head injury, but I see one falling and "taking" the other with him, directly or as a result of the survivors' decisions.
Check this book out: Red Eagles: America's Secret MiGs (General Aviation): Steve Davies: 9781846039706: Amazon.com: Books
I think you'll really enjoy it if you're on a fighter pilot kick. Tells the story of how we acquired and kept secret MiG jets out at Groom Lake for our dudes to train against.

Robert Churchill's Human Rights and Global Diversity. He argues for the universalism of human rights.
If the only available rope was manilla, therin would be a problem as it deteriorates pretty quickly.
Interesting, some countries (not western) consider HR a liberal western construct which doesn't apply to them. As an illustration it would be like applying a legal construct of their country on the west as a whole and urging every nation to sign up to it.

All true. Churchill considers that the cultural relativism argument, and disagrees with it. He posits that a human right is based on being a human in a social setting. A right denied, to Churchill, is not prima facie proof that the right is a privilege. It's simply proof of repression.
The point I find debatable is that a nation will do an R2P deployment due to a shit storm somewhere or other and certain folks get all bent outta shape because the R2P guys that go in are allegedly committing HR violations, forgetting of course the HR violations the original cum stains were doing. There is a War on Drugs, a War on Crime, we hack this, hit that, all quite violent language but when it comes to real actual mano a mano, it becomes a different mind set. Train for warfare but don't hurt anyone when you do it.
