Reference: The Ultimate Wood Joint Visual Reference Guide

Dating all the way back to Neolithic times, the mortise and tenon is the oldest wood joint known to mankind. While the specific provenance of the joint is unknown, I’m willing to bet the inventor wasn’t a virgin.

In the thousands of years since, craftspeople have developed an almost absurd variety of joints, some of which you learned in the ID shop at school, some of which you’ve never heard of, and that one that you can always see in your head but have forgotten the name of. To help you remember for the next time you’re building something out of wood, or to give you some alternatives for any current designs you’re working on, here are some visual guides:

More Evidence Of How Copyright Makes Culture Disappear In A Giant Black Hole

A few years ago, we first wrote about the supposed missing black hole of culture due to copyright, based on some excellent research by Paul Heald, looking at the availability of new books on Amazon based on the years they were published. It produced this chart:

As you can see, there are a bunch of recent books, then a huge drop off… until a sudden spike at 1922 — also known as the year before which nearly all books are in the public domain. That giant gaping hole on the right side of the graph should be pretty distressing. It counters the totally false narrative by certain legacy copyright system supporters that copyright is necessary to get books published and also that without copyright, no one would bother to sell the works, because they could just be copied by others. But, more importantly, it shows how much important culture is totally locked up because of copyright law — unable to be published by those who’d like to offer them, and not worth it for the copyright holders to actually publish.

Late last year, EU Parliament Julia Reda published a similar chart concerning the EU:

That one also looked at books, in the same manner as Heald’s original research. On top of that, Heald himself has continued to explore this issue, including comparing new books to used books and also looking at the music space.

Now we’ve got even more evidence of how copyright kills such culture. Europeana has taken a similar look at a large corpus of digitized works in Europe and mapped it out. Guess what? Despite being a totally different data set, the graphic looks astoundingly similar:

Of course, the "black hole" in this case only goes back to the early 1940s, rather than the 1920s, because copyright terms in Europe tend to be life plus 50 rather than life plus 70, but there have been some efforts to change that as well.

Once again, this should raise serious questions about the problems of copyright term length. It seems fairly obvious that at their current length, copyright terms are actively suppressing a ridiculous about of cultural output, much of it likely to be lost forever to history — as by the time it actually goes into the public domain, it may not even exist any more. This is a pretty big problem — especially given all the claims about how necessary copyright supposedly is for protecting culture. It seems fairly clear from these charts that it’s frequently doing the opposite.

And yet… rather than fix this aspect of copyright law, policy makers seem to be focused on making it worse. The final version of the TPP agreement forces all countries who sign on to move to life plus 70 instead of life plus 50. It’s likely that the TTIP agreement will include some similar provisions.

Every time we post these charts, we also post this chart from William Patry’s book Moral Panics and the Copyright Wars, which showed the copyright renewal rates on various works in 1958 and 1959, back when you had to "renew" your copyright after 28 years.

As the chart makes clear, for most types of works the copyright is clearly worth basically nothing after 28 years. Movies are the main exception, as are some maps and at least some musical compositions (this was in a time before sound recordings could even get a federal copyright, though I imagine those might have a decently high renewal rate, probably at least on par with musical compositions).

All of this should raise serious questions about why we have copyright terms that are so long when the vast majority of content doesn’t value that protection and (more importantly) the clearly visible harm to culture and public knowledge created by such long copyright term lengths. And, again, it raises the question of why we don’t move to a system whereby copyright holders should be required to renew their copyright at specific intervals, to make sure that such monopoly rights are still more valuable than the public interest in those works.

And, in the meantime, anyone pushing for longer copyright terms, given how much of this information is now out there, is outing themselves as someone who is clearly against the public interest and shouldn’t be taken seriously. And that includes the current negotiators from the USTR who pushed strongly for the copyright expansion in the TPP in the face of all of this evidence.

Suppressors affecting velocity

UntitledDustin Ellermann recently conducted a simple test in which he shot various firearms of varying calibers through a chronograph with and without suppressors on each, in order to test their velocity. The overall findings are that, yes suppressors will increase the velocity of a round, with the exception of the .223 in his specific test, […]

What WWII’s Top Secret Spy Manual Can Teach You About Wilderness Survival

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Before there was a CIA or an MI6 there was the Special Operations Executive. And, as WWII heated up, it put all of its collective tradecraft knowledge into a single training manual. And, it turns out that training spies to operate behind enemy lines is often good training for going outdoors, too.

The abridged history of this manual is that, as America’s participation in WWII became more and more inevitable, the British and American militaries identified the need to train a corps of spies who could operate behind enemy lines, leading groups of partisans, or conducting their own intelligence gathering or sabotage. Spying, as it’s understood in the modern context, was a very limited profession at the time, so a method had to be found to impart the knowledge of a few to many students, across multiple training camps. That was achieved in part by enlisting specialists to train students in specific skills, and these camps had incredibly high instructor-to-student ratios as a result. But, the basic program and its knowledge base also had to be written down. So, the SOE did just that, creating its own training syllabus.

The best surviving copy of that syllabus happens to be the one used at Special Training School 103, or “Camp X” which opened to train American spies two days before Japan bombed Pearl Harbor. It now resides in the United Kingdom’s National Archives in Kew, a suburb of London. Quotes from it are used in this article.

The pre-war approach of Camp X scaled quickly as America went to war. While only 760 Americans ever received the training detailed in this manual, it formed the basis for the training program implemented by America’s new Central Intelligence Agency when that was formed the next year.

That original manual was unearthed by Denis Rigden, and is re-printed in its entirety in his book, “How To Be A Spy.”

What makes it particularly interesting to us outdoors types is that this knowledge is drawn from a time before modern technology invaded the battlefield. A time before exploding cigars or microfilm cameras or night vision goggles. Its shared knowledge is what proved successful in the field, during wartime and its presentation here is ruthlessly efficient. It’s not politically correct or the kind of advice that’s been run past lawyer’s to absolve its authors of liability. It’s what enabled early spies to parachute into enemy held territory, blow shit up, then make their escape.

Let’s go through the manual, pull out the knowledge that’s applicable to us hikers, sportsmen and nature lovers and discuss how it’s still relevant to us in the modern world.

Observation

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

This is as true of climbing, hunting or simply crossing challenging terrain or dealing with a dangerous situation as it is plotting enemy movements. The syllabus also emphasizes the importance of ensuring your information is up to date. A detailed assessment achieved the day before is invaluable for forward planning, but take some time to ensure that what you saw before remains the case before you move.

Camouflage

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Not just for hunters. Anyone who wants to observe wildlife or who may need to ascertain the motives of a strange group of people in the middle of nowhere can benefit from these general practices. And, the syllabus emphasizes that you can quickly adopt the principles of camouflage on the fly by using terrain or brush to mask your silhouette. It also identifies motion as the thing that will give you away. Simply remaining still will prevent people or animals from detecting you nine times out of ten.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Understand the different kinds of camouflage, as defined by the syllabus, is key to successfully hiding from observation. This is a great example of how these different types can be used together, enabling you to totally disappear into your environment while remaining ready to act.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Light, shadows and movement are how effective camouflage works. Actual color matching is far less important.

After those are achieved, worry about making your outline with disruptive patterns, eliminate your shadow by pressing yourself closely to the ground or an object, then consider the overall tone of your background and attempt to match it.

The syllabus goes onto recommend you cover yourself in natural vegetation to achieve the above goals, but cautions against using this method in hot sun as the plucked branches and whatnot will quickly wither and become, “worse than useless.”

Using natural features, vegetation or manmade materials to mask your silhouette is an easy, immediate way to disguise yourself.

Optics

The syllabus going into the importance of reading animal movements at length. I’ll spare you the couple hundred words by simply saying: become familiar with the behavior of birds and other small animals in your area, they’re frequently a dead giveaway to the presence of humans or large predators.

Staying Hidden At Night

Crossing A River

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Crossing moving water is dangerous. But probably less dangerous than jumping between wet rocks. The potential for a fall injuring you or knocking you unconscious, then dumping you into moving water, just has very serious ramifications. Any river crossings need to be calculated, planned and conducted with extreme care.

First Aid

The priority in any first aid situation is to first assess the person’s airway, breathing, and circulation. Understandably, the syllabus deals mostly with injuries causing blood loss.

What WWII's Top Secret Spy Manual Can Teach You About Wilderness Survival

Tourniquets are a controversial first aid technique and should not be attempted without training.

Self Defense

The syllabus goes into much more detail, but it’s largely oriented around killing, so we won’t reprint that here.

How Can The SOE Syllabus Help You?

A lot of this stuff, like the camouflage or silent movement techniques, may at first seen overwhelming. The title of this paper is a giveaway though. As a syllabus, it’s an overview of training, not the complete package. The concepts and techniques identified would have been taught and practiced in classes. And you can do pretty much the same thing, applying what you read about here to your next outdoors adventures.

A nighttime dog walk, for instance, is a great time to practice your night vision techniques. A hike is a great time to practice silent moving. Basic camouflage can be applied any time you’re outside, simply by dressing in earth tones and using natural features to disguise your silhouette. Work up to it, then find a deer or other wary animal and try to sneak up on it. I bet you’ll be surprised at not only how achievable that can be, but how effective all this stuff combined is at improving your experience outside. Minimizing your presence outdoors is the best way to observe nature.
