- Fundamental analysis is a method of evaluating securities by attempting to measure the intrinsic value of a stock.
- Technical analysis is the evaluation of securities by means of studying statistics generated by market activity, such as past prices and volume. Technical analysts do not attempt to measure a security's intrinsic value but instead use stock charts to identify patterns and trends that may suggest what a stock will do in the future.

A snippet of a (yahoo messenger) conversation with a friend who thinks differently. "... friend: i'm actually quite happy being a follower with technology... i'd rather build cool apps than hack frameworks. Its similar to my approach to investing... get on board a stock just as it makes new highs :-) and ride the wave. ..." Viewing technical skill acquisition (including the choice of language/frameworks/tools) through a metaphor of investment of scarce resources (that would probably benefit from the use of a deliberate strategy to maximise returns) is illuminating. The metaphor fits loosely, with plenty of holes in it. The "investment" made by a developer in a particular technology (and thus by implication in the underlying paradigm, community, toolset etc) is primarily the time he spends on mastering the technology, and secondarily the mental effort required to do so (Kernel hacking is much harder then Ruby on Rails). Mental effort is not strictly equal to time consumed. If you have 24 hours of free time you can use it to work through a RAILS tutorial or understand continuation passing interpreters. The latter requires significantly more mental effort/unit time. Spending time, however, is very different from spending money. Money does not diminish when you don't actively spend it(ignoring the time value of money), but the time available to you diminishes at a constant rate till it is all gone whether you consciously spend it or not. With money, you can make a marginally suboptimal investment, watch it for awhile, then re extract most of the value and reinvest it in another instrument without too much effort, losing just the "time value" of the money. You can't decide to learn RoR for a year, then extract most of the time invested, and reinvest it in say Kernel Hacking. Time, once "invested" is gone forever. Like most non professional investors in stocks and shares, developers mostly invest their time into particular technologies by default rather by deliberate strategy and many people find themselves having "6 years experience in C++ " or whatever, without knowing quite how they got there. So it is useful to look at the "correct" ways of investing in shares and try to extract any lessons to apply to tech skill acquisition. My friend's technology strategy is "similar to .. get on board a stock just as it makes new highs .. and ride the wave." . In the world on Finance, such a strategy is called "technical investing". When the objective of the analysis is to determine what stock to buy and at what price, there are two dominant methodologies.- value investing and technical investing. from investopedia

"Comics" bring to mind Mickey Mouse, Archie, Superman and other "read and throw" reading. But there is no reason why the presence of pictures need to limit the range or quality of the story. Stretching one's mind, it is even possible to imagine truly excellent stories conceived and distributed in comic format. "V for Vendetta" was originally released as a comic. The film's the director made it a "chick flick" with V falling in love with Evie (gag!! Anyone who had read the comic had their heads explode at this "romantic" development in the film). Constantine's lush and rich multi-realm occult backstory was dumbed down into a monochromatic Christian good vs evil fairytale in the movie. Both stories are the worser for conversion into film. If you'd like to experiment with comics for adults, try Neil Gaman's Sandman series or Alan Moore's Watchmen. The latter was the only comic ever to win a Hugo award or be featured in Time magazine's list of 100 best English novels. It is a really good book. Even within the standard comic book framework, read "The Killing Joke" or "Arkham Asylum - Living Hell" for examples of what a creative team can do within the constraints of established backstory. The former explores the dynamic of the Joker/Batman animus (The sequel of Batman Begins is rumored to be based on this comic , at least as far the Joker's characterization goes) and the latter explores what happens when a rogue investment banker attempts a "not guilty by reason of insanity" plea to avoid jail and lands in Arkham Asylum. Batman is seen in about 3 panels in the book. The rest of the story is set almost completely inside the walls of Arkham and in spite of a slightly uneven "summon the Devil" subthread is a good read. PS : the one series you want to avoid is Alan moore's Promethea. This is a story full of feminist nonsense splattered over a half baked understanding of the Jewish Tree of Life, and even some (equally halfbaked) Indian mysticism!
