My favorite thing to do is try and understand how the world works. This is what gives me go, and it’s the purpose of this website. Whenever I have something shown to me, or I “discover” something I add it to my ever increasing body of knowledge that I use to analyze the rest of the world. Ultimately, the goal is to find the unified theory of everything (trite, but true).

I am sometimes rather lumbering when attempting to express myself, and it bothers me greatly. I’ll think I’ve assembled something worthwhile only to find that it collapses under the scrutiny of “many eyes”. This is embarrassing, and it hurts my ego when it happens. The common-sense approach is to simply not overextend — to be very careful with every word, research extensively, and don’t post anything if you aren’t 101% sure. That’s safe. That’s professional. That’s mature.

Meh…I can’t do it. My obsession with learning is so compelling that I simply must share what I “think” I know about the world. I do this for selfish reasons that may seem counter-intuitive, i.e. I do it to learn just as much as to teach. In other words, I am actually sort of gaming the system by putting forth my ideas framed as “lessons”, while simultaneously hoping someone will come along and show me why I’m wrong.

This is no attempt at manipulation or gesture of false humility. I truly want to be shown the flaws in my viewpoints. Here’s what I wrote on the matter back when I first started this *log:

Being right is boring, not knowing is through-provoking, but being wrong is absolutely exhilarating.

The unfortunate consequence of the fervor with which I put forth my ideas and viewpoints is that I occasionally often overextend and come off looking dumb. As I said, this irks me immensely, and because of search engines my bouts with stupidity will haunt me forever.

But you know what? I say fuck it. I’d honestly rather overextend and fall over than never make the attempt. I think the debate is worth it. I think what we all learn from the discussion is worth it. If I have to look stupid sometimes just so I can put a thought onto paper, so be it.

So to you who are reading this, I ask that you forgive me when I stumble. Please don’t confuse my strong assertions with arrogance or the belief that I really do have all the answers. I don’t. I’m looking for them, I want them badly, and I’m willing to occasionally look like a fool to get them.

The difference between me and a typical evangelist is that I have no loyalty to my opinions. I just want to be right. I truly don’t care if I’m right when we start the debate or if I’m right after it’s over. Either way, I’ve either learned something or helped someone else do the same.:

I’m constantly amazed by the number of people who seem to have learned nothing during four years at university. Until recently I’ve wondered how it was possible, but now I think I understand.

People who learn a lot in college are the people who had questions floating around in their heads before they got there. They’re curious. They have a sense of wonder about the world. As such, when answers (or provocations) are offered, they are subconsiously paired with their natural curiosity, and learning ensues.

Those who don’t benefit from school simply aren’t tuned to the world’s questions, and as such they are unable to appreciate potential answers. I finally groked this when I asked myself why I didn’t learn more in my programming classes in college.

The reason is now very clear: it wasn’t interesting to me. I thought I was going to be a sysadmin, or a “networking” guy. I didn’t really know what I was going to be, but I was damn sure it wasn’t going to be a programmer.

Because of this I went on autopilot, i.e. the mode where you say to your brain, “Temporarily absorb the minimum required to get the grade you want in this class. Nothing more.”…and that’s no way to learn.

So what’s the answer? The answer is for parents and teachers to foster within children curiosity and interest in a wide range of subjects. Don’t impart knowledge, per say, but the thirst for understanding. This way, when the opportunity to learn something presents itself it will be embraced enthusiastically instead of being ignored or mechanically processed for a short-term goal.

Here’s the list of courses that have been opened up to the world for free by MIT.

(and by the end of the year they’ll have every class they teach up there…)

Now if I can just figure out how to get this stuff into audiobook format. How about a business model where you take the free MIT content and make it into audiobook format? Now that’s a good idea…

A short beginner’s explanation of why you can’t truly “hide your IP address”.

Hiding Your IP Address

Here’s another old post of mine from 1997:

The more questions you have floating around in your mind at any given time, the more answers you can glean from day to day experiences. You can see it like this: knowledge and truth are jumping out of every experience, yet unless you have the appropriate question or curiosity associated with that body of answers, you will not learn anything.

So basically, you need two things to be able to expand your mind. You need to have the questions and/or curiosity, and you need to have experiences that have the potential to be learned from. As one or both go down, you become limited. As one or both go up, you grow.

Nothing deep really, but I was only 23.

I’ve posted about this before, but if you are a reader and don’t use LibraryThing.com — you’re missing out.

LibraryThing lets you archive, rate, and search your books, as well as compare your collections to those of others. It’s totally amazing. I just signed up for the life membership for just $25.

A very cool piece that closely follows my line of thinking:

http://www.markshuttleworth.com/archives/28

I’ve been thinking a lot about how to get to the next level in my field of information security, and I’ve come to a pretty interesting conclusion:

It’s not really possible to just study in this field — you have to implement each thing you’re trying to learn if you want to get the full benefit.

Now, yes…I realize this is true of just about every field, or even skills in general, but it’s especially important in fields such as information security that bcth focus on fairly complex concepts, but also on being familar with a myriad of specific technologies. In other words, in order to be good in information security, you can’t just know that RBAC does a certain thing. You also have to know how that plays out in the real world. Specifically, you have to know how to implement this concept in various operating systems and applications.

Duh

Again, this is fairly well accepted. Most good InfoSec practitioners have a fairly stout lab at home to play with. So I’m not just saying, “Build a lab and practice what you learn.” What I’m saying is that when you want to get to the next level, there’s a certain path you should follow.

Set a Project-Oriented Goal

When you want to learn how to do something, don’t set out to do it at all. That’s the tendency, and it’s a bad one. Don’t try to learn Python, for example; it’s not efficient for probably 80% of people to sit down with a book or do a series of example exercises. Instead, find a project you want to work on and use Python to do it.

Now this will inevitably lead to you doing some academic studying of the subject, to be sure, and that’s a good thing. In fact, I do strontly recommend learning concepts before diving in, but when you set out to truly understand something — to really feel it — you need to be using it to accomplish a real-world goal. It can’t be for the sake of it. Learning like that doesn’t burn in the same way as it does if you’re learning for a purpose.

Examples

• Instead of reading the Stevens book on protocols, enter a Honeynet Challenge and use the book.
• Don’t read three books in a row on Lisp. Take a program you’ve written in a previous language and redo it in Lisp. Use your three books as a reference.
• If you have a question about an OS vulnerability, start a VMWare session and run the exploit. Stop reading about it and do it. You can read about it as you’re waiting for the VMWare image to copy over.
• Use whitepapers as references, not as textbooks. If you try the latter, you’ll end up with information overload and little practical experience. Instead, start a project using said technology and keep the whitepaper by your side.

That’s a very short list, but hopefully you get the idea. Again, I’m not saying not to read; I have a book by my bed, my toilet, in my car, and anywhere else I might spend 15 seconds. I am big into learning underlying concepts and I don’t think that should ever suffer. The issue is that you can’t actually do so if you don’t implement.

Conclusions

The bottom line is that I think the human mind can be adversely affected by trying to cram information into the brain that lacks a foundation. The foundation being the implementation that you’re stacking this high-level knowledge on top of. It’s almost as if the brain takes in some sort of interesting concept, pauses, and then says, “Ok, show me.” And if you don’t show it, the brain then says, “Hmm…didn’t quite get that — must not have been too important.”

So imagine the concept phase of learning as being like making pottery. You have wet material being shaped into a form you’ve never seen before. It’s new, it’s fluid, and it expands the mind. When you’re done with this phase you have a new shape, but it’s fleeting.

If you want to keep said form, you have to put it into the oven at very high heat. That’s the part that hardens it into place and makes it solid. Well, that’s the implementation phase of learning. You have to lock it in. If you don’t, you’ll have a bunch of warped, wet goo sitting in your brain. And with every passing day each of these non-hardened pieces it will lose more of their form. Eventually you’ll have to re-make the pots (relearn the concepts) if you want to use them, i.e. you’ll have to study whatever it was all over again.:

As I’ve mentioned in previous posts, I’m back playing Table Tennis. The group I’m playing with now is the best I’ve ever been exposed to, and my drive to improve my game has never been stronger (it’s hard to get motivated to excel at technique when no one can even return your serve). With this group I get beat more often than not; it’s an excellent environment for me to grow in.

Anyway, my main focus now is on properly generating power, i.e. using the correct technical movement to do so. The study of how to do this is precisely why I love the sport so much. Effectively generating speed (and especially spin) is euphoric.

My latest realization, or re-realization actually, is that tension kills power.

This is a “re-realization” because this is the sort of concept that I already “know”, but am unable to transfer into action. Basically, when I see my serve come back long with underspin (just how I wanted it), I immediately tense up as I get into position to loop.

After I execute I realize immediately that my shot was neither that fast nor that spinny. Why? Because I was all tight and restricted. I know this, I kick myself for it, but the next time I get back a return where I want it I do the same damn thing.

I have the same problem in Golf, actually, which makes this more than a post about Table Tennis. It’s natural for people to associate power with tension. I find with my Golf shots that when I “don’t try” — especially with my short irons — I can hit some incredible shots. I am at the point now where I tee off for most par 3’s with no more than a pitching wedge. That’s roughly 150 yards or so (the tee helps) with ease. I am not tight, I don’t swing hard, I just do the motion.

When I do this it feels absolutely amazing. I get the perfect Titleist click with no vibration in the club and my ball goes flying like I wound up and swung as hard as I could. Of course when I try to swing hard, I can’t get half of that power. But over and over I have to remind myself of this. I go for entire days struggling with consistency and power until I force myself to “start over” with the basics and relax.

So that brings me to Table Tennis. I am doing the exact same thing there, only my loop form probably isn’t even as good as my 9 iron shot — which is sad since TT is my favorite sport.

Ultimately the problem is simple — I’m still associating power with tension.

Once I can break this mental link I’m going to become very dangerous. I am starting to see the power of a relaxed grip in practice, but once I get into a match I tighten up to generate power. I simply have to figure out how to make a full turn, a full uncoil motion, and remain loose during the entire process.

The frisbee throw is really a good analogy for the backhand. Imagine trying to throw a frisbee a long distance if you kept your throwing hand tight and controlling. You couldn’t. The power of the throw comes from the ability to release fully from the coil. Once I subconsciously make that connection in Table Tennis my rating’s going to jump by a few hundred points almost overnight.
