difficulty fillin in PDF form?
You are probably using acrobat professional and you are trying to edit your pdf. That's why when you click on it acrobat load the font from your system and it takes some time. Use the form tool which is much easier to use in this case.

Difficulty in setting permanent iptables on Debian
Ok, first a clarification, did you use the instructions from the Debian Wiki, or did you use the iptables-persistent package? They operate via different mechanisms. The Wiki page is basically describing a manually way of accomplishing what iptables-peristent does.If you installed iptables-persistent, did you put your iptables rules in the file /etc/iptables/rules. v4 (as described in the iptables-persistent documentation)? If not, that's probably your issue. Try configuring your iptables rules the way you want them, and then run either:orIf you did not use iptables-persistent, but copied the changes required by the Debian Wiki page, you will need to show us the modifications you made to the files, the if-pre-up script you added, etc.UPDATE: The iptables-persistent information above is for the package in wheezy (testing) and sid (unstable). For squeeze (stable), the file should be /etc/iptables/rules. Unfortunately, I do not have an easily accessible squeeze/stable based box, so I can not look closer at iptables-persistent on it right now

The difficulty of Monster Hunter Freedom 2?
i dont think you should use dual blades as your first weapon, trust me... i've tried to use dual blades when i first started out, and i died numerous times... i've just went with the long swords. Start of with the bone, and keep upgrading it until u get the bone then the bone Wolf, (dont get the black katana MK, too hard to get and a waste of time) Shark, then you are free to choose your pass from poison, fire, or more raw dmg. you should work on combos for the long sword, my choice is circle(stab), R(Slash), Triangle(stab), R(Slash), then finally, trianglecircle(slashjump back) hope i helped, i got the game about a week ago also but i have a bunch of friends at my school who tweak on the game and they help me alot

Difficulty faced in solving maths problems
I find the same problem, also I am around your age so I can relate. Sometimes I feel like mathematical papers are written to be complicated. However, I think that most of the problems concerning being able to reproduce an argument given in a book or paper has to do with not understanding the argument in English. What I mean, is that people (me especially) have a bad habit of understanding the symbols but not being able to explain the concept to a 5th grader. For instance, if you read about the proof for the fundamental theorem(s) of Calculus, you might just miss the entire point of the argument in trying to understand the symbols and notations of the argument. In reality, understanding the argument has more to do with being able to translate mathematical jargon to English. And if you want to be able to write proofs, you have to be able to translate the English into mathematical language. This is easier said than done, and I am sure most never really learn how to do it, that's why we have so many horrible mathematical papers. But if you learn how to do that, you wo not have to memorize math, you will only have to memorize concepts. Also, do not think that these mathematicians that use complicated jargon are smarter than you, they most likely are similar to your intelligence. They have more experience, but in the end, they will mess up in ways very similar to us. So if you apply all the above and still do not understand the concept or argument, move on to a different source.

How is the difficulty, grade of a Boulder defined? What objective measures are used?
If this question is in reference to North America, then we are most likely talking about the V-scale. Created by the legendary John Sherman himself, this is the grading scale most commonly used in the US and Canada, and was created down in Hueco Tanks, TX in the late 70's - early 80's I believe. As stated above John Sherman is the man responsible for coming up with it as a more accurate response to the very ambiguous system of B-ratings. The B system conceived by John Gill in the 1950s was a universal rating scheme for bouldering, having three categories: "B1" was defined as ". the highest level of difficulty in traditional roped climbing", "B2" was harder than B1, or "bouldering level", and the grade "B3" designated a route ascended only once, although tried by others on several occasions. When a B3 was ascended a second time, it was reclassified as a B2, or B1. Gill's idea was to attract climbers to the "new" sport of bouldering, but discourage turning that sport into a numbers race. His system depended heavily on traditional climbing standards, long before sport climbing came into existence. It was assumed that the scale would shift as traditional difficulty levels rose. Thus, e. g. , a B1(1958) would be easier than a B1(1968). (Wikipedia)You can see why with the rapid progression of climbing grades why this system quickly became a hindrance to the quickly evolving sport of bouldering. So John "Vermin" Sherman, considered by many to be one of the father's of modern bouldering, devised a new open-ended system that would be more consistent across the full range of the sport. The new system only takes into account the difficulty of the problem and not other factors such as objective dangers and whatnot. The V is derived from, you guessed it, John's moniker of "Vermin".I highly, highly suggest you do yourself a favor and get a copy of John's book " Sherman Exposed: Slighty Censored Climbing Stories". In it you will learn how John came up with the V scale along with many other epic adventures. His prose is witty and downright hilarious most of the time. Absolutely required reading for our fair sport, you will learn quite a lot about climbings history in North America for the 70's and 80's, I think. In a totally captivating way to that makes you want to get there and adventure. I hope this helps.(I almost forgot. I am getting a camera though so I can take a bunch of awesome climbing photos.)
