  1. That was code injected to run on your site. Code Injection post something like: <?php "<span><font color="red" size="20">Owned</font></span>" ?> into the name field and click "Send Message". Your approach is unsafe as everyone has been trying to tell you.
  2. Yeah, that's just one of the Animal Planet mock scientific documentaries that they did. They also produced "Mermaids: The Body Found" if you are interested.
  3. I do understand the power of eval, I understand the power of eval to allow hackers to execute their code on your page. http://br2.php.net/manual/en/function.eval.php It is quite possible you might be able to safeguard your own variables. Now can you make the same claim for everyone else who might use your method? If not, then you are exposing them to unnecessary risk and worse not even acknowledging this fact. It is certainly not just us saying this. You can look up "eval hacks php", "eval alternatives", "eval is evil" and see much the same. What is old is new again I can't say I'm huge on security for anything I don't have a personal stake in, but I do like to see it done well if at all possible.
  4. Potentially allows for smaller chips, ternary system and reversible computing. Translates into something smaller, faster and more energy efficient. Just to be clear, there a number of different methodologies being attempted at present. Edit: Removed part about quarks, not sure what I was looking at there. Too easy for net malarkey to find a home in my brain :/
  5. I don't want to ever land on a secreted runway.
  6. Not sure on speed, but if someone is able to change the evaluated variable they can end up owning another user's session. I hadn't even heard of any real eval hacks for years now, since most everyone avoids it like the plague. "If eval() is the answer, you're almost certainly asking the wrong question." – Rasmus Lerdorf, creator of PHP
  7. Nuclear waste can be obviously radioactive, but you are less likely to be exposed to it than pollutants from more common processes(coal, oil, etc.). Not sure what you mean in terms of water. Typically the two-stage process limits environmental radiation exposure to extremely low levels though. The reactor borne mutation thing is pretty much a myth. I spent months sleeping near a reactor and got more radiation exposure from sunlight. I would actually go back there and try and soak up some of what it put out in hopes of gaining some of the positive benefits from low level exposure. Now in the event of accident, bombs, you find a magically glowing powder, yes, you should worry about exposure. Mostly in terms of radiation poisoning. Otherwise you are pretty safe around them.
  8. I don't even see all that much "hate" for it here, on a regular basis. None of these oppressive regimes(in terms of pseudo-communism) happened here. Didn't get the brainwashing of the Cold War era. Mostly only ever see it come up is in some Politician's talking points(almost always a Republican). ie. "Program X, is communistic and this is why I, Bob Everyman, stands against it!" Bombastic bull crap. Nothing anyone with more than two brain cells should take seriously. Broadly generalizing, I hear more raging about it from Eastern Europeans online than anywhere else. I understand where they are coming from. I can't imagine any amount of "that is not what Communism is actually about", would mean much to me if I had gone through what they and their families did. From my POV the actual attempts have done well. Communal associations of free individuals pooling their talents and resources, to make themselves and likewise their communities better off. I think economic systems run more on inertia than anything else. Almost always takes a drastic regime change for something different to arise.
  9. Recursion is similar repetitions, in this case repeated function calls. To really understand recursion though, you need to understand recursion. Just joking, a good real life example is the effect you see standing between two mirrors. Can even draw parallels between this and what is being asked of you.
  10. That was more the fault of the party dictatorships than the economic system. Typically they bastardize their economic system into one with the State running and owning everything. That isn't what communism was originally envisioned as. There are a number of examples out there, communes, monasteries, co-ops, where the sharing of resources and mutual decision making have worked out quite well for the participants. Even the employee owned company could be considered a form. edit: CharonY beat me to it
  11. That just takes all the fun out of treating it as a totally factual reference. Establishing a timeline of events for the arrest of Jesus is another good one. Treating the Gospels as eyewitness reports.
  12. Undefined: X * 0 = 5 --> 5/0 = X Indeterminate: X * 0 = 0 --> 0/0 = X There are many numbers that when multiplied by Zero equal Zero, but there is nothing that when multiplied by Zero that equals 5. This is how I generally view the difference anyways.
  13. Either: A) it had no effect prior to or B) it would have made Adam and Eve immortal If B is true then God apparently didn't care and Adam and Eve just happened not to have already eaten from it. I don't see this as casting anyone in a good light, so I prefer A. As far as gaining a moral sense goes, I was really thinking in terms of metaphor not as a literal interpretation. If you want literal then God asked for good behavior from people lacking knowledge of good and evil. One can only hope that the whole thing was part of His Plan and that Adam and Eve weren't being punished but merely sent on their way as God intended from the start.
  14. Marmite is yeast extract, the B12 is added in later. While I'm not sure on the bacteria's exact requirements herbivores harbor them as well as every other animal, so presumably the bacteria would be fine getting what they need from inorganic or plant sources. It is generally recycled internally, but inevitably our own bacteria manage to toss some of it out and the effects of a deficiency are nothing you want to test on yourself.
  15. Bacteria are actually responsible for producing B12(cobalamin). Requires bacteria living in animals or artificially grown bacteria to produce it. I do find the generally used semi-artificial form(cyanocobalamin) somewhat dubious personally since it can leave trace amounts of cyanide. My own thoughts though, I'm sure I've had it already with no noticeable effects, especially considering the Veggie MRE's I've eaten(more candy on average).
  16. They were apparently free to eat from it up to that point. Not recorded if they ever did or did not though, as far as I could tell. http://www.biblegateway.com/passage/?search=Genesis%202&version=NKJV I read this as God saying Man would instead live a finite time if they ate of the Tree of Knowledge. Not that they'll necessarily keel over then and there. Worst case He could just have an odd definition of the word "day" which we do have a good bit of evidence for. Even afterwards He didn't verbally forbid access to the Tree of Life. Possibly He realized the sheer contrariness of His creation by that point... Instead He assigned some pissed cherubim with a sword to keep the humans off His lawn.
  17. I'd advise a good bit of reading rather than further speculation. If you really want an answer then "curvature of space-time" is the best one we have at present.
  18. We'd probably be hosed honestly. Asteroid(s) - Dust - Famine - Riots At that point they are pretty much free to come in and do whatever they feel like. Personally if I were them I'd just launch aerial attacks. Decimate any remaining agriculture and then send in robot drones to scour the surface. Possibly they could work in some quasi-religious angle and convince survivors to come out of hiding, congregating to one location.
  19. I look at it as a metaphor for obtaining the intelligence that allowed us to formulate moral values. Freedom from death is then blocked by a "sword" often used to represent War. If you want the literal, they were never forbidden to eat from the Tree of Life. Presumably it just did not have any effect until after they had eaten from the Tree of Knowledge.
  20. You can put the link in your signature as well. Then all you need to do is post like normal. ie. BBC Horizon: 2010-2011: What Happened Before the Big Bang? Attempting to drive traffic using multiple posts on a discussion forum is generally seen in a negative light, regardless of the reason. Your signature, in contrast, is this nice little thing that follows every post you have ever made; where you can share a tastefully presented link to something that others may find of interest.
  21. I'd recommend making a few lists. What sort of mechanical/computational problems am I having in my daily life? What could I make to help my friends or family? What could I make to help the environment? What do I use now that could be made better? Once you have your lists you can start brainstorming possible solutions. Feel free to use this site as a sounding board. Decent breadth of knowledge at your disposal.
  22. Yeah, creep resistance is most likely reason. There are stainless steel ones out there too though. Likely just depends on the application and material costs. Been awhile since I looked Inconel up. I'm thinking it was for a similar reason too.
  23. That should work. I don't want to comment on "correctness" as I don't know your teacher but I think most would consider that as thinking along the right lines.
  24. I'm not sure "clever" is the word I'd use, but I've always found the pro-entropy Universe bringing about Life which increases the amount of entropy, to be thought provoking.
