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.

Meteorite going down over russia

31 posts in this topic

So this just happened this morning.

 

http://www.guardian.co.uk/world/2013/feb/15/hundreds-injured-meteorite-russian-city-chelyabinsk

 

I think this is the best footage I have ever seen (has ever been recorded?) of a meteor entering the atmosphere. Hooray for cheap, modern technology!

It's amazing that the shockwave was able to break windows below and even collapse the roof of a factory, considering the trajectory probably went 20km or something above the ground! EDIT: 30-50km

 

I hope the people injured recover quickly, all the best wishes to them.

 

Edit: As Milcho pointed out, that was actually a meteor. Meteorites are the ones actually hitting the ground

No one warned about it? No one knew the damage would be considerable (ppl injured), in the case someone detected the meteor?  "so dont worry, is not a missile" ?

Did they just hide the fact cause they could do nothing about it, so probably better not scaring anyone?

Thats so fucked up man, I though humans where well capable of detecting things like that

From the information I gathered it was virtually impossible to detect:

 

- Relatively small

- Fast moving

- Coming from the direction of the sun

I know a lot of people were hurt, and this isn't in disrespect to them, but holy smokes was that amazing!

 

I used to go out in the desert in Arizona to watch any meteor showers I could see, and they're just little tiny streaks in the sky, but this is a lot more fascinating to watch.

I know that there's a number of similar but smaller events that occur somewhat commonly on Earth, but its always cool to see such a big meteor on footage.

Also, wasn't it Meteor if it doesn't hit the ground, and meteorite if it does? 

 

And on a hilarious note, one of the Russian party leaders apparently called this "a test of new American weapons,"

Whoa. I don't know what I would do in such situation. Either stay put and be friggin' scared, or grab a car and try to see the site of the impact :D

I guess you're right. Apparently, I don't know anything about that stuff... let's just call it a space rock.

Even the huge ones surprise us sometimes, if they come from the wrong angle. Space is a very big and very empty place.

And objects like this can have very long cycles, meaning they only pass within detectable ranges every few thousand years or so.

 

It's not at all unthinkable that we would only get a few months or weeks warning before a flying mountain slams into us.

It's a very real danger to our life on earth, and one of the reasons space exploration is vital for our survival as a species.

Well, i don't know - i'm asking cause even the site you linked calls it a meteorite (and presumably the Guardian, which is somewhat reputable i guess, does its research). 

I'm not sure of the exact classifications, like for example, if the meteor breaks up and pieces fall to the ground - are those pieces meteorites or is the meteor now called meteorite?

 

Space is a very big and very empty place.

This doesn't necessarily apply to floating rocks and such, but space being very empty makes some types of detection easier. What I'm thinking of is that one site that talked about no stealth in space - but it was generally based on radiation differences - so an object that has a significant (a few dozen kelvin?) temperature difference from space (which is near 2 Kelvin or so) should be easily detectable... at least in theory.

I'm not at all surprised over news outlets getting that wrong... They commonly confuse "galaxy" with "solar system"... (thats like confusing planets with grains of sand...)

Hmm. Ok i'm confused,

 

Russian Metor 30-50Km above ground, caused massive fireball and (probably) exploded in the air.

 

2012 DA14 will pass within about 17,200 miles, thats approx 27Km, but nothing to worry about!

 

What am I missing here? (apart from my morning coffee ;) )

What am I missing here?

From a quick google search: 

The asteroid will pass 27,700 km (17,200 mi) from the surface of Earth.

So.. perhaps a factor of 1000? :)

You are missing a few decimals.

17,200 miles is approx. 27,000Km wink.png

Opps, thanks Madhed and Milcho. In my head I treated 50km as 50,000km for some stupid reason. I knew something was wrong, just couldn't see it - I blame lack of coffee ;)

 

At least the Earth is safe for another day ;)

30-50 km? That looked something like a few hundred meters on the video.

 

Pretty cool though. I'd love to see something like that.

I also saw the video and uaaauu! That closed, right next to us? Makes you wonder how fast the dinosaurs disappeared.

Things like this remind me of how vulnerable we still are from these dangers.  Tracking the big ones is one thing, but do we still have a ways to go from being able to plan the mitigation of future impacts from them?

Petty vandalism, ftw!
...but we forgot to spray-paint "Kilroy was here" on the meteor.

Alternatively he could be reading km as kilo-miles instead of kilometers...

damn, i woudn't know what to think if i saw that streak across the sky.

 

i hope this get's people thinking more about advocating space exploration, this could have easily been a decimating event.

 

A funny thing in the comments of the OP's link, the people are talking about how if this had just happened just a couple decades ago, we might be all hiding in nuclear shelter's right now.

Really?

I thought it was a joke.

C'mon, Russia is so big and empty. It's fairly difficult to hit a town. Well, shit happens I guess!

It seems only 20 people were hospitalized. I guess they have all been "lucky" somehow, I know a dude who were struck by a blast years ago, it isn't pretty, I hope they'll be fine.

Nah, they're cool now, dropping random shit.[attachment=13647:RussiaMeteorShit.png]
