The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

  1. [quote name='Tachikoma' timestamp='1317056253' post='4866132'] One way to visualise how light is affected by gravity, imagine space time is like a flow of a tide or a medium and you are trying to go against it. At some point the tide is going to so fast that you can not counter it at your maximum speed, therefore you are swept with it... into a black hole. [/quote] Black holes are not the only things to effect the speed of light. Explain this.

  2. [quote name='irreversible' timestamp='1317054449' post='4866115'] [quote name='dysphoric' timestamp='1317053344' post='4866106'] If a neutrino were traveling faster than light, it doesnt mean that its traveling backwards in time. Time is not a real, its a manmade concept. Our concept of Time moves at the speed of light so if anything it would be moving forward in time at a faster rate than the universe itself. [/quote] You're right - time is not real: it's part of something [url="http://en.wikipedia.org/wiki/Special_relativity"]more fundamental[/url] called spacetime. Passage through spacetime happens at constant speed (an increase in velocity is only possible at the account giving up velocity of passage through time) according to currently accepted theory. If the neutrino violates this limit then it violates the most fundamental physical limitation there is and in this case would effectively travel back in time. Consider this where the x-axis is velocity through space and the y-axis is velocity through time. By maximizing your velocity through space you minimize your velocity through time. At a certain point (light speed) you reach a limit where time literally comes to a standstill. According Special Relativity nothing can travel underneath the horizontal axis, which is precisely what happens when you cross this threshold. [center][img]http://upload.wikimedia.org/wikipedia/commons/thumb/b/b1/Relativity_of_Simultaneity.svg/220px-Relativity_of_Simultaneity.svg.png[/img] [/center] [/quote] Yeah that makes sense except the fact that you'd travel backwards in time. If you traveled faster than the speed of light from point A to point B then you'd arive before a wave of light traveling the same distance at the same time. If we apply that to spacetime, then you'd arive at a point in time faster than the rest of spacetime, thus traveling foward into the future. Edit: Okay no...Sorry Im an idiot and I need sleep lol. If you arrive at a point before it happened then you're effectively traveling backwards. Duh. Forget my other statement.
  3. [quote name='SiS-Shadowman' timestamp='1317053772' post='4866109'] [quote name='dysphoric' timestamp='1317052035' post='4866101'] Uh, Photons do too reach the maximum speed of light.....[b]Photons are massless particles[/b] that move unhindered because gravity only exerts a pull upon things with mass.... [/quote] That's not true. Photons DO have a mass, however they don't have a rest mass (I hope this is the right word, in german it's called "Ruhemasse"). If photons had no mass then light could not be bent, however it is possible in extremely strong gravitational fields. These kinds of distortions are actually used to detect black holes (the quiet ones ;) ). *edit* I can't find an english source, but [url="http://www.quantenwelt.de/faq/masse.html"]this[/url] (beware, german) is what I'm talking about. But according to that source, "bewegte masse" (moving mass, or something like that) just seems to be another word for energy. It renders my comment somewhat pointless [/quote] Thats such a contradictory statement. How can a photon have no resting mass? When is a photon standing still? In order to slow a photon down it would have to have mass..... I think newtonian gravity is flawed.
  4. [quote name='irreversible' timestamp='1317052673' post='4866103'] Eelco, it's not my intention to postempt your preemption, but I'd just like to point out that the notion of time travel could be far more elusive if this were to be true. If the bulk of information is limited to light speed and [i]regular matter is bound by that limit as such[/i], then for all intents and purposes a particle that travels faster than light is travelling back in time. I do not claim that time travel is possible, which is why I wrote: "[color="#1c2837"][size="2"]It would also rattle the cage we live in very unexpected ways". IF harnessing this were possible in practice, then sending bits of information doesn't necessarily amount to time travel in a traditional sense.[/size][/color] [color="#1c2837"][size="2"] [/size][/color] [color="#1c2837"][size="2"]Also, while I'm not too well versed on the topic of neutrinos, it is my understanding that they are not that well understood themselves. Based on this I have to assume that it might not be possible to use neutrinos to carry information so much as they are relics that simply are. I don't think Relativity Theory is in any danger of being debunked. Neither do I think the Standard Model is or String Theory are for that matter - while String Theory is a topic in and of itself, there hasn't been a case in history where either the Standard Model or Relativity Theory, when applicable, has fallen flat on its chest. Yet, the Standard Model is literally missing its most important component. If this implies anything, then it is that we're not wrong, but we're rather just not there yet.[/size][/color] [color="#1c2837"][size="2"] [/size][/color] [color="#1c2837"][size="2"]Regarding time travel - I mentioned nothing about the arrow of time. Also, on a side note - it might be an interesting dabble into science fiction to open another topic and try and fantasize what the arrow of time actually is and why we perceive it the way we do. Because I don't believe anyone really has an idea.[/size][/color] [color="#1c2837"][size="2"] [/size][/color] [color="#1c2837"][size="2"]>> The upheaval will mainly be theoretical rather than practical.[/size][/color] [color="#1c2837"][size="2"] [/size][/color] [color="#1c2837"][size="2"]Let's agree to disagree in that I prefer to remain more hopeful and wouldn't put something as fundamental past the [/size][/color][color="#1c2837"][size="2"]next [/size][/color][color="#1c2837"][size="2"]potential[/size][/color][color="#1c2837"][size="2"] great discovery just yet, even if the discovery itself might be postponed beyond my lifetime. Although, I do agree that there doesn't seem to be much practicality in this at face value.[/size][/color] [color="#1c2837"][size="2"] [/size][/color] [color="#1c2837"][size="2"]At the end of the day, though, the guys at the lab went public with this because they couldn't figure this out on their own. They could be poking out their left eye tomorrow morning when some 13 year old points out that they'd accidentally switched their gear to imperial instead of metric when someone spilled their morning coffee.[/size][/color] [/quote] If a neutrino were traveling faster than light, it doesnt mean that its traveling backwards in time. Time is not a real, its a manmade concept. Our concept of Time moves at the speed of light so if anything it would be moving forward in time at a faster rate than the universe itself. I'm sticking with my negative mass concept. Possitive mass gets pulled by gravity. The more mass the more it gets pulled and the slower it becomes. At 0 mass (photon) there is no pull or exertion and so it is allowed to travel unhindered. If you apply negative mass, instead of gravity pulling, it would push. If you push something thats already traveling at the speed of light it would travel faster, logically. However its not possible for a particle with positive mass to travel at the speed of light. The universe actually slows what we call time down when approaching the speed of light so that it remains impossible to achieve. Instead we can move objects and a very close fraction to the speed of light.
  5. [quote name='Eelco' timestamp='1317046265' post='4866066'] [quote name='irreversible' timestamp='1317034827' post='4866006']It would also rattle the cage we live in very unexpected ways. For instance, sending information back (and possibly forth) in time might all of a sudden become a practical problem rather than a theoretical one. In other words, if these results were to be confirmed, we could be in for quite a ride. [/quote] Let me preempt a few pages of rambling nonsense: no, that 'might' not happen by any reasonable interpretation of the word 'might'. Relativity never even hinted at the possibility of time travel (im affraid you are confusing relativity theory and science fiction), and neither will whatever theory comes out of this. All we know theoretically and experimentally is that one can put a damper on the passage of time; nowhere is it implied that one can qualitatively change the arrow of time, infact relativity theory explicitly requires this cannot be done, and this experiment doesnt change a single thing about that fact. The core ideas behind relativity will remain firmly standing of course, notwithstanding sensationalism to the contrary. This result is entirely consistent with the notion of a fundamental speed limit to propagation through the vacuum; and all this entails, ie the core tennets of relativity theory. Perhaps just like most particles, photons dont quite reach that maximum speed. The vacuum is to photons less 'empty' than to neutrinos, since a photon would interact much more strongly with whatever there does be, in terms of quantum fluctuations or trace amounts of particles, so it makes sense from that point of view; if mass isnt the only interaction to hinder a particle from moving through the vacuum at full speed, then neutrinos would be a good contender to photons for the candidate of fastest particle, since they are very light indeed and barely interact with anything at all, as opposed to the rather promiscuous photons. The upheaval will mainly be theoretical rather than practical. String theory or other hubristic frameworks which start out by taking the speed of light as an axiomatic property are all in rather deep trouble if this will be confirmed. [/quote] Uh, Photons do too reach the maximum speed of light.....Photons are massless particles that move unhindered because gravity only exerts a pull upon things with mass....since it has no mass gravity can't slow it down and so it travels at the maximum speed of the universe. Also, its possible to travel faster than the speed of light by using negative energy to bend spacetime.... therefore it is possible that the neutrino possibly has the effect of bending spacetime or it consists of a negative mass.
  6. Front-end programmers need art experience.....back-end do not.
  7. You don't need to be good at math, you just have to understand complex math statements, operations, proceedures, algorithms, tables, variables, equations, and formulas.... To me, being good at math means being able to solve complex equations quickly, ussually in your head. I suck at doing that.....and I hate math....but I know how to get my answers. If you dont have a strong grasp on mathmatics principles and advanced mathmatics, then forget intermediate programming. Logic, problem solving, geometry, trigonometry, algerbra and basic math are all fundimental pre-requisits of learning to program on a professional level, to be efficient, your next step is a general understanding of data structure, processing and transfer, hardware and os programming (knowing limitations of target hardware and systems, memory usage, utilizing multithreading when possible, hardware accelleration, etc etc.).
  8. It's possible that the mass of the neutrino has been misgauged. We have proved that energy with a negative mass can exist (see: Negative energy) through experimentation. If negative energy is possible to produce then particles with a negative mass exist. If a neutrino actually had a negative mass, it would theoretically be able to travel faster than the speed of light without changing the current models of physics.
  9. Much thanks.
