...for starting with main() and breaking the program out into whatever logical blocks it breaks into (if any). Then do the same for each block until you reach a block size (hunk of code) you're comfortable with understanding. Take the block you're most interested in (that you think is most related to your assigned task) and get a good understanding of it. Recurse back up the call tree to understand the bigger context in which that block is used and just keep going until you know enough to do what you've been asked to do. Take notes so that you can refer back to them when you have something different to do. As you do more maintenance you will eventually develop a set of documents describing the entire program.
I know, the question is about tools. I've used some monitoring tools that help me understand call flow and find hot spots of inefficiency during execution but, honestly, the best analysis tools I have are, in order:
vi grep (Used with all it's flags and a few pipes, the BEST analysis tool EVER!!) bash sed And the suite of text tools that come with every Unix/Linux distro.
Analysis is no fun but I know of no short cuts to understanding code that don't involve all or some of above process.
Typical of a spoiled hypocritical neo-crat nut job. You hate the country that through the sacrifice of many young lives and the work of agency's you love to hate, provides you with the safety and comfort to smugly sit back and spew this idiocy. You undermine the very system that allows you to exist. The fun part will come if our way of life does fall to it's enemies people like you will be the first to bend over and take it up the ass because you're made of jelly.
You should move to your favorite middle eastern country and try to do what you have the freedom to do here. In the words of one of my favorite celebs, "See you in Guantanamo...".
Figures, anonymous coward!! Sort of says it all doesn't it!!
The "mother" and "father" (I'm a step, not there when it counts) that failed to give the child values rather than condoms. I suppose if she wanted to do Heroin your solution would be to teach her about methadone? I've two other kids that have made it to marriage without any such problems.
The problem with people like you is that you want to force everybody into your warped idea of normal where sex without commitment is just fine and normal and unavoidable. Just use a condom or a pill or an abortion. I don't care how you live and if you like the toilet go drown in it! Just don't teach my kids your bankrupt morality. People do grow up and get married having never had sex with anyone but their spouse. It's a good thing and statistics easy prove that out. Teaching children otherwise is damaging and destructive not only to the individual but to society as a whole. It may sell MTV and Victoria's (lack of a) Secret but otherwise it's a cancer on us all. Unfortunately an army of morons like yourself have descended upon our schools to teach kids how to destroy their lives before they've even started. Wait until we decide that theft and murder are inevitable so we'll just stop trying.....
As step father to a girl that started having sex at 13 (no, I wasn't around) and is now pregnant at 15 I would say that if you're having sex before you're married you get what you deserve. If you wait until you're married you are much more likely to be prepared for the responsibilities that come with having sex. The fact that, as a society, we've lost all direction as to right and wrong about sex is just a another signpost of our ultimate demise. We teach "little" girls to be "sexy" and then we're suprised when men act on that. We teach men that sex is just a bodily function and we're suprised that STD's are out of control. We sow what we have reaped.
"In recent years scientists have begun to view the existence of life outside of our solar system as ever-more likely"
Oh yeah, I'm sure we all agree with that statement!
After 50 years of listening and looking we have, let's see, ONE suspicious signal that never repeated. Well if you consider that good reason for belief I'm not so sure why so many of you have trouble believing in God.... Having worked with several groups that are committed (and some should be) to the search of ET I'm less convinced than ever. Twenty years ago I was certain, now, not so much....
"It should be possible to design a completely idiot proof reactor that would automatically disable itself in the event of coolant loss. Dunno why reactors aren't designed like that from the start."
It is and it was. Way back in the 50's Freeman Dyson created an idiot proof reactor that when it reached a particular temperature the fuel actually caused the thing to shut down. Prototypes were built and demonstrated and proved. I forget the details but it was, of course, forgotten in the irrational rush to declare all things nuclear to be BAD(tm)...
Not one spec of evidence exists for this proposition. Not one. Ever. Weather is cyclic and the cycles are longer than humans live and longer than humans have been paying attention to weather. Learn it, accept it, get over it.
Jeez, if you want a totalitarian government to tell you when and where you can fart move to Russia. Don't try to sell it here.
Next time you're stuck on the third floor of a burning building I'll be sure to send a 5' 2" (90lb) beauty to carry you on down.... Don't be stupid. You can site all the great studies of how women are tougher, take pain better, can do so many things that men can't and at the heart of all of them you will find a dedicated nut pounding a round peg of an idea into a square hole. The fact that your reactions weren't quick enough to deal with a particular female is meaningless (maybe you're a little slow, you sound like it). You should consider the fact that she was in total defense mode while you were on the attack. Thousands of years of human history will not be nullified by idiotic studies to prove up is down and black is white and women are tougher than men. If they were they would have been dominating society from day one rather than wait for men to invent birth control and tampons.
I'm a fairly large fellow myself but it hardly matters. Even if I were 5' 10" and 150lbs (average) the "average" women wouldn't stand a chance. Sure, there are women that could kick my ass, but the typical man is stronger and more physically able than the typical woman and the strongest of men will always be stronger than the strongest of women. Always has been, always (despite the feminist onslaught of disinformation) will be.
As to agression, I have to agree with you. Being the father of sons and daughters I can tell you first hand the boys can't hold a candle to the intense nastiness a young lady can unload. Boys get mad and fight and get it over with (normal ones). Girls get even.... Sometimes repeatedly and with great vigor....
As to the war. Geez, where do I start! I notice you had to go back to the 19th century (before we were a super power) to cite incidents. Of course we had to take it. We had no means of retaliating in the 1800's (not reasonably). Now we are the last super power and everybody wants to take on the big guy. If the big guy bends over and smiles they'll be more than happy to do the rest. That's what we've been doing and that's why guys like Ahmadinejad can spit at us and WE apologize for provoking him! That's what I'm railing about.
As to NUKES and DIMWIT's, well, man, you really need some help. Here, let me give YOU a clue. Iran doesn't have nukes beyond the most basic components, if they did, Isreal would destroy them (with a little covert help from us) before you even knew they existed. Even if Iran were allowed to develop an actual weapon they still don't have any way to deliver them (not a trivial problem). Granted the former Soviet Union could sell them something but considering the required sophistication to make it work I doubt we have much to worry about. That's also disregarding the airborn laser and other anti-missle systems that have come online in the last 6 months. They're made just for pissant losers like Ahmadinejad that think they can hold the world hostage with an armory of 1 or 2 nuclear missles. Let him try.... Please....
I'd offer you a nickle so that you could buy a clue but I'm afraid it would cost a lot more than that to put wisdom in your head son. Do a little more study before you try to instruct others.... I also suggest you work on your speed and try wearing a cup. If little women are giving you trouble, and you're a big guy, maybe physical type stuff isn't your game.... Try board games, at least they're fun!!
Yeah, talking worked so well for Neville Chamberlain didn't it?
What is it with women and the "dick is bigger" thing. A hell of lot more women get their breasts enlarged than men get penis implants. That tells me who is worried about size more and who has the more shallow view of themselves and others.
That aside, those that think we can talk or negotiate or appease our way to safety or security are simply foolish and unfamiliar with history and preditory behaviour. Unfortunately, because women are weaker physically, they tend to default to a stance of negotiation rather than meeting agression with agression. A stance of non-agression is great when your enemy is weak and can be ignored. Our enemies are not weak and cannot be ignored. If we don't aggresively defend ourselves we will lose this war. In any real world situation there are those that are dominant and those that are subservient. Don't care if you don't like it. That's how it is and, despite what many women seem to like, being on the dominant side is safer and more comfortable.
Though I agree with much of what you say your conclusion is flawed.
Men and women have never been equal and never will (or could) be. Any boob (no pun intended) can take one look at women and men and see (drum roll please) that MEN ARE PHYSICALLY STRONGER THAN WOMEN! WOW! That means that there are a whole slew of things that men are more suited to doing than women. Allowing women to push their way into these roles makes everyone else pay for their arrogance. Feminisms (and homosexuality's) solution to this is to mentally castrate men and convince them their the same (equal) to women. The more society buys this lie the worse things will get for men. The ultimate conclusion of this is, of course, that we become so weakened that our enemies will find us easy prey. The current world politics bare this out. Consider some of the threats made by middle eastern countries. No President of the first half of the 20th century would have taken these insults and provocations without some retaliation. Now a piss ant country like Iran takes hostages and we try to talk them into giving them back. The female influence on modern politics. Ultimately resulting in confusion for weaker countries and their place in the world resulting in wars and death.
Sorry ladies, some things in life are a mens only club and, like it or not, that's not gonna change.
Ok, you win! Most obnoxious post award including foul language AND blasphemy in a way that's sure to offend virtually anyone with a modicum of class. What a mouth you've got (or keyboard).
Yeah, go ahead and call me bad names, you know you will.....
"I'd be bloody pissed off if anyone took my car and home, whether they're from here or not."
Of course you would. That's my point. If people wanted to immigrate here to work, integrate, and live by our laws I wouldn't have a problem with it. I've lived in several large cities and loved being around people from all over the world. They add a special spice (differences) to life that's just great! However many of the illegals coming here now:
1) Don't integrate. There are migrant worker groups that live 15 or 20 to a hotel room and are
simply here to make as much as they can and send it home. A percentage of these are dedicated
criminal operations. Many live in communities of their own ethnicity and cause major problems
because they refuse to be Americans. They want to be Mexican in America.
2) They don't speak our language (english) and don't want to. In California and New York they get
angry that you don't speak spanish (or spiclish) to them. It's infuriating and liberal idiots in
this country want to print everything in two languages to accomodate the illiterates. It's maddness.
3) Again, they are breaking the law simply by being here without following the damnably easy process
to come here legally. It's not like the US makes it hard. I hate competing with the educated
immigrants that come here but they damned well have a legal right to do it. Mexicans (though many
are not from Mexico but South America) won't even go to that trouble. They blatently ignore our
laws and expect our welfare system to pay for them. Which brings me back to the original point.
You wouldn't want someone to take what's yours. Nor do I. I pay taxes to support our government services, hospitals, emergency rooms, many things that support our society. Illegal aliens take these services without paying for them. Americans suffer because of this. We've had about a dozen hospitals on the Texas border close because they simply couldn't afford to stay open. They were legally obligated to treat illegals but had no way to make them pay for the services. They were overrun and now the hospitals are gone and the Americans that paid for them don't have their care anymore. That's my analogy to taking what's yours and making you keep paying. My taxes haven't gone away (in fact they go up every year) but now I don't have hospitals I can go to because Mexicans, esentially, stole them.
I'm a live and let live guy too but when someone puts a gun to my head I feel obligated to take a firmer stance. We're at a point that if we don't defend ourself's we'll lose a war without ever knowing we were in one. If 20-30 million (yep, that's the number) illegal aliens entered Australia over a period of ten years I think you'd have a better feel for where most Americans are right now. This is not immigration it's an invasion. The fact that our President spends as much time hanging out with Mexico's Present as he does with our Secretary of State really says it all.

So another village idiot has awakened. This is news because?
If she was stupid enough to reject nuclear before who cares what she thinks now...
Ehhhh, how fast does sound travel in space again.....?
Isn't it illegal to use the "N" word on Slashdot? I thought this was a "no nukes!" "no nukes!" "no nukes!", zone.....
Next thing you know you'll be talking about clean, cheap, inexhaustible energy that's totally independent of foreign resources..... NOT!!
You have but to listen and look..... The "signal" is all around you.
Actually the "signal" lasted for 35 years. Try again....

You know, that's the nicest, most inspirational thing I've ever read on this blog. Thanks for that posting.

"You are arguing with way too much passion and too little reason. I don't think, I'll be following-up to you again.."
Yeah, right back at you. Mom always said, "Always wear clean underwear and never argue with crazy people". Words to live by....
