Thus reducing the energy involved in the impact. That's all I've been trying to point out. Collision detection always works by letting everything run until something intersects with something else and then calculating an appropriate response for this collision to "undo" the intersection. If you smooth steps between the current predicted state and a new position packet you reduce the amount of energy exerted in this collision response, leading to a more stable simulation; less chance of a major explosion. It doesn't fix the issue, it just makes it less of a problem.
The downsides are obviously added latency and that the cars seem detached from the laws of physics. "Floaty." Those may or may not make the whole proposition a non-starter depending on what your requirements are.

I'm not sure.
Shotglass brought up collision syncing and I don't think I quite understand what he meant. As far as I know there is no syncing going on other than what you get through position packets. Nothing specifically relating to collisions at least.Indeed, which is what I've been saying all along. It would help, but the general collision response code would need work as well before it's properly stable. Smoothing would only bring multiplayer collisions up to the level of the single player ones.
Would it be that much worse than the current "syncing" though? Seems every client is running physics for itself and then it just handles any bad predicitons the best it can once updated car positions arrive. Doesn't seem like collisions are synced in any meaningful way. Or am I missing something?
Yes, but not that far inside each other after a single physics step. You'd avoid cases where the car suddenly moves, for instance, 1 meter sideways across a single physics step when a packet arrives and all that energy get transferred in any collisions that may occur as a result. Instead you'd get a less extreme collision as the engine slowly moved the car 1 meter sideways over a number for physics steps.
This assuming the smoothing was also applied to active physics bodies in the simulation and not just a visual thing of course.
I just want to recommend this really interesting, 7 part series of articles from Newsweek. Apparently they've had reporters following the Clinton, Obama and McCain campaigns from behind the scenes on the condition that their findings weren't released until after the election.
They really make you appreciate just what cluster****s the Clinton and McCain campaigns were, and how well the Obama campaign was run in comparison.

Oh please. Everyone but the entire right wing, which is was busy kissing Sarah Palin's feet then? The amount of bile spewing from that corner suggests not everyone worships the man.
US politics has always been about hero worship, so why it suddenly scares you this time around I have no idea. Your candidate didn't win perhaps?
EDIT: On the topic of hero worship; I find this a few orders of magnitude more scary than any Obama-worship I've seen to date.

It's a combination of both I think. General collisions certainly need improvement as even against AI it's a bit erratic, but I think part of the reason you get these explosions is that when a new position packet arrives you effectively get a car's worth of mass moving to the correct position in one 100th of a second. If another car happens to be in the way when that happens the pure momentum involved results in a serious shunt.
Smoothing would reduce the distance a car could move each physics step, and that would probably reduce the risk of getting physics explosions as well.

Instead of the cars snapping into position when a new position packet arrives over the net (as seen in LFS), the sim smooths out the position change when new packets arrive so you don't get that jerky movement. This neccessarily introduces some more latency on top of what you already get over the net and may also make the cars look somewhat detached from the laws of physics, but it looked rather well done in that clip.
LFS could absolutely benefit from something like that, yes. For one it'd make door to door racing against a lagging player a little safer.
I was prepped and ready to hate that video, but that does look rather good doesn't it? I liked the interpolated car movement. Looked very smooth. Are car to car collisions handled properly as well or do you still get the occasional moon flight? The dirty tires seemed a tad exaggerated though (based on my non-existent experience with real single seaters). Is the grip dropoff really that bad IRL?
Anyway, looked good enough that I shall give it a another whirl once the patch is released.
Most likely you've left F-lock on? Alternatively not installed the keyboard's drivers?
And the reason they don't want to call it that is that the word "marriage" gives you certain rights that civil unions don't. The two are not equivalent in the eyes of the law, which is the whole point.
If you can find me a Marine, I'd be more than happy to. The whole thing's been nothing but a pointless waste of human life, and the only thing you've accomplished is cementing the hate for the western world in the minds of yet another generation middle eastern children.
At least he won't be out of a job any time soon...
What was that? In many cases the US elections are more important to us than our own, ****ed up as it is. Just look at the current financial troubles.
Srsly? I never knew. What would be the appropriate word for a "classy man" so I can properly insult Andy?
My "problem" is that you get all holier than thou about a few Brazilians booing Anthony Hamilton, but then turn around and act like a class A, prime quality prick upon seeing Massa's father getting disappointed. Classy.
Sounds about right...
This is where things get complicated you see. As far as I've been able to tell civil unions and marriages have the same legal rights... in California. The problems come up if you want to move to another state. You cannot "transfer" your civil union to the other state and get the same benefits there. That only applies to marriages, so using the word "marriage" is essential to ensuring equal rights.
I'm not sure what you were trying to say there, but you got the words for "tits" and "thank you" correct, so you'd probably do just fine over here.
Yep, same here. I remember we were actually given a choice between EN-US and EN-GB when first starting college and the teacher would grade accordingly. Elementary and Secondary school were strictly EN-GB though IIRC.

Watching those videos I suddenly became a full 200% more content with being completely disconnected from most aspects of popular culture. I shall from here on in embrace old fartyness and marvel in its splendour.It was purely an argument (EDIT: actually more of a snarky comment) against your usage of the word "activist". I made no comment on the issue itself. Think of it as an amusing observation from an outsider.
EDIT: Oh, and I write British English, in which "polarise" is one of two allowed spellings.
If I had gone into teaching, chances are I'd be a murderer by now. I don't have the patience.
I just read, write and listen to English an awful lot. It's actually gotten to the point where my Norwegian is suffering and I struggle to construct proper sentences without resorting to English turns and phrases. A bit pathetic really. Just don't ask me to speak English or I'll melt into an embarrassed, stammering puddle on the floor.

I love how every right wing American uses the exact same words to describe their opposition in every controversial matter. Without exception it's some ridiculous hyperbole to used to vilify the opposition and further polarise the issue.
Is there some newsletter you all subscribe to in which the hyperbole of the month gets circulated?
Not having even heard of djmag.com I must admit I'm a little bit puzzled to see someone so excited about it to actually make a thread here. What is it? Some ranking, an award show? Is it somehow more prestigious than Heat Magazine's top 250 punk-rock hairstyles?
I guess that'd be a "no" to your question...
