Quote from evilpimp :Funny stuff with the LFS guys dancing haha.

That's a pretty kinky gay club. (Guys dancing to techno music, with funny suits on.)

But I agree it's a brilliant movie.

How NOT to discuss an issue, in 5 easy lessons:
Quote from Fischfix :ok lets face the facts:

1. Call your view on the matter "the facts", "reality", or "the truth".

Quote :everyone who wants can drive to the pits and spectate then, all the others can wreck their brains out.

2. Tell the other side that it's their problem.

Quote :do you wnat to force everyone else to enjoy the game exactly the way you enjoy it?

3. Exaggerate the others' opinion so it looks like tyranny.

Quote :end of story.
[...]
period.

4. Declare the discussion closed after you've had your say.

Quote :DON'T BE SO ANAL

5. Accuse the others of being immature.

Quote from Victor :
Slip fraction
-------------
This is the dynamic value of the current combined slip ratio relative
to the combined slip ratio that would provide the greatest force.

0 to 254 - slip ratio increasing up to maximum force available
255 - slip ratio exceeds the maximum force slip ratio


Can anyone explain what this combined slip ratio means? Can I view it as the fraction of the "traction budget" that has been used? Or is it really a slip ratio, i.e. a ratio between the actual motion of the wheel and the motion of the car (and if so, how is it combined)?

I would like an option to reduce post-race wrecking. When I have just joined a server, I use the post-race time to do a few laps and get into the rhythm. But quite often this preparation is ruined by wreckers or by guys who just park in the middle of the track. And a couple of times, I couldn't even finish my race because I was wrecked by someone who finished early (I was in mid-field, and he crashed into me at the final turn).

I must admit I don't see a perfect solution.
  • Going into AI mode after finishing would help, but it takes time to clear the track after the race.
  • Automatic pitting could help, but determined wreckers can then leave the pits and continue wrecking.
  • A rule that automatically pits any car that crashes might work, but looks artificial.
  • Any other penalty (e.g. time, loss of grid position, DQ) for people who crash would also punish the innocent.
Quote from Cue-Ball :There is an easy solution to this problem: Server admins.

Sure, but that takes effort from the admin. If LFS could guard against this behavior, it would raise the standard of racing on servers that are admin'ed less intensively.

Quote from Dru :sounds like an un-feasible suggestion for purely pickup racing.

It would be a server option anyway.
Quote :If you don't like what people do at the end of the race, just spectate immediately

Doesn't that mean that you lose your position on the grid at the next restart?

Quirks:
  • When you press Escape while dragging the slider, you first get the menu, and when you return from the menu, the replay-rewinding starts. (I expected the drag to be canceled.)
  • When you move to the start of the replay, the screen is black. (I expected to see the first frame, or at least the "Paused" indicator.)
Suggestions for buttons:
  • Fast-forward button to control the speed (left-click == F2; right-click == F3; wheel-click == reset speed to 1.0).
  • Button to move to the start of the next/previous lap (as measured on the leading car).

Quote from Victor :btw, we store GForces in the RAF now. Only at one byte though, so it's a bit grainy, but it's there.

Thanks!

There is a problem with the RAF file that you can download. This RAF file has a sample frequency of 10Hz, against 100Hz for the standard RAF files from LFS. (The RAF file was probably condensed to save download time in the LFSW Analyser.)

When you load this file into another analyser, the analyser reads less samples, and will calculate a lap time that is 1/10th of the actual time. One effect is weird values for Longitudinal G force (10 times too high).

(The real cause is the fact that the sample frequency is not stated in the RAF file. Existing analysers have 100Hz hard-wired.)

Possible solutions:
  • Add the frequency to the RAF format.
  • Download the full RAF file (if it is still available).

Say "That sounds interesting, and ... Oh, hold on, something is going wrong in the kitchen / with the kids / with my cat". Then put the phone down and have coffee.

Another trick is to always let your phone ring 4 times. Automatic dialers employed by call centers always stop there, because they don't want any answering machine kicking in. (Because that would waste their precious time. :really

Misc remarks:
  • Something weird (graphically) happens when I select "Show all" from the Flash context menu.
  • Could the splitter bar between the map and the graphs be a bit wider? It's hard to position the mouse on it.
  • A steering gauge is missing from the "Overview" display.

Quote from Victor :Though i fear that would break RAF compatibility.

In the RAF format definition, the block sizes are not fixed; the block sizes are given in the header. It ought to be possible to append data to the dynamic wheel block without breaking existing apps (provided they were programmed correctly).
Quote :There are only 3 unused bytes in the dymanic wheel block, and I can imagine this value should be a float.

There are 3 forces (lat, long, load), so that's 1 byte for each force. Let that encode for its colour in the forces view inside LFS (e.g. 0x00 = green, 0x80 = yellow, 0xff = red).

Quote from thisnameistaken :all my free time is too easily consumed by repetitive pleasure-seeking

That happened to me too. In my case it was an escape from a job I didn't like, but couldn't quit for practical reasons (family, mortgage, etc.) I felt like I was stuck, but couldn't face the facts. Games and TV were just tranquillizers, and only added to the problem because they cost me hours of sleep.
Quote :Anyone else find they hide windows containing anything they've created from spouses/significant others if they suddenly enter the room unexpectedly?

No, and I find it worrying that you do. It's normal to become more critical of what you created, because your knowledge and experience grow -- but your skills should grow too. And some folks have always been too afraid/self-critical to publish their work; they were built that way -- but you're not one of them.

If you have become scared of showing new stuff to others, even your SO, then you lost an important way to build your self-esteem. Things you do in your job can also give a sense of accomplishment, but (judging from the Smiths quote in your profile) I guess they don't. IMHO you should think long and hard why you get scared.

Thought experiment: Imagine making a big change in your life. A career in a different field (writer, musician?) Moving to another country. Studies. Travel. Or a different SO. Ponder the changes. You may reject all of them, but what's important is how good your reasons are for rejecting them.

If all else fails: start a family. All these worries become futile when there is an infant crying in the house. (Warning: when the diaper days are over, they problem returns with a vengeance.)

Quote from Victor :i wonder how useful it really is though. Those forces are fun to watch, but you can't really tell anything from them...

It will become useful if Scawen adds data on the adhesion limit to the RAF file.

Quote from Gekkibi :Interesting. I have never bought BMW, Coca-Cola, Red Bull, IBM, Siemens, Nokia, etc because there is a ad on racing event. Am I special?

Either you are special, or you are ignorant about advertising. The effects of ads have been researched to death. If it was so easy to ignore ads, and not be influenced by them, then advertising wouldn't be the multi-billion dollar business that it is.

Perhaps your buying behavior is not influenced much. But that won't be true for the guy next to you on the starting grid. On average, the ads work. And if they happen not to work in simracing, then the companies won't pay much to get them displayed, so the server admin still needs to find other funding.

Quote from Gekkibi :Isn't the data in .raf for a reason? Meaning that if it wouldn't be there (And it would be encrypted) it would be like watching encrypted TV-broadcast..?

No, it's perfectly possible to have a RAF file without the setup data. The reason to include it is, I guess, what Victor pointed out: to quickly see the differences in the setup, so you can see their effect on the car handling.
Quote from RocksGt :If you want to extract the data with the information of the graphs it could be more effort than making your own set

It's more effort, but only needed once: to make a program that reverse-engineers the setup. After that you can use the tool many times, and also give it to others.
Quote :what people is complaining about is that you can get a really good set (that the owner could spent hours on making it) in a moment and without effort.

That is not correct. You can not get a full setup from a RAF file. You only get a small part. The diff settings, toe-in, camber, caster, tyre pressures, and wing settings are not available.
Quote from RocksGt :The system to inscribe people in the races make use of LFS-World times, both online and HLVC. That is mandatory to participate in the league races, so we can be sure times are valid (because of the HLVC's check).

In that case, people who worry about "spying" could drive their hotlap with a "semi-perfect" setup, and use their real setup only in the actual race. (I assume that the hotlap is only needed as proof that you are fast enough to take part in the race.)

Quote from SamH :Everybody skins their cars up to the hilt with branding of their own, or brands they have a fondness for, or just brands they think are cool-looking. If the skins feature were taken away, you guys would all have an issue.

I wouldn't. I don't use skins. I have skin downloading switched off, partly because skins cause an fps hit on my old PC, and partly because the skins distract my eyes from the racing.
Quote :The CTRA has taken many thousands of man-hours to create, and it takes both money to run it, and literally hundreds of man-hours a month to keep the standards up.

Sure, running a good server costs money. Then charge for using it. Ask Scawen to create a system for transferring money from the LFS accounts to the server operators. If you want to bring in the economy, then do it for real: give users a choice between racing on free + ad-filled servers and paid-for + ad-free servers.
Quote from Christopher Raemisch :I challenge you, imagine any race event, both LFS and Real life, without quality adverts and banners and ads.

.. then you'd have racing like it was in the 1960s and before. Pure, un-stickered racing. Yay!
Quote from Stigpt :If the billboards are skinnable, they can be SOLD. That means MONEY.

Correct, and guess where that MONEY comes from. From the RACERS that visit the server. Because if the ads can be sold, that means that they work. And if an ad works, it means that the people who see it will buy stuff -- things that they wouldn't have bought otherwise.

In short: if you fill your server with ads, you are extracting money from your visitors. It would be the same as when you charge directly for the racing, except that
- the racers don't know how much they pay, so
- they can't choose the server that offers the most value-for-money, and
- the stream of money is indirect, so there is more overhead cost, and the racers will pay more for their racing.

And finally, as Woz pointed out, non-optional display of ads quickly leads to an arms race like we have seen on web pages: ad blockers, encrypted ads, DRM, animated ads, popups, etc.

Quote from MaKaKaZo :Will it be possible in the future to have 'full' private setups in spr files?

The only sure way to do this is by disabling generation of RAF files from the SPR. Even if the setup data is omitted from the header, then you can still derive part of the setup from the telemetry data: if you know the forces, position and speed of each wheel, then you can reverse-engineer the suspension and brake values. (And getting the gear ratios is dead easy anyway.)
Quote :In our community we've come to the extent of deleting HL replays from lfsworld so other teams don't have access to our private setups. Even people who beat WRs won't upload them to avoid espionage.

That sounds a bit paranoid to me. Which part of the setup is "leaked" by the SPR file, and is so critical that you need to keep it private? And how much can someone gain if he copies these settings from your team's setup (assuming he already has a reasonable setup of his own)? Does it make much difference in the race result?

+1

The learning cycle (drive -> get telemetry -> analyse -> tweak setup -> drive) is far too long now. Generating RAF files on-the-fly would be a huge improvement.

A RAF file can only hold a single lap, but that isn't a problem: you could create multiple files, with an automatically generated filename (e.g. <server name><datetime of race start><lap number><laptime>.raf)

Quote from -Willi- :Is it ok that you show all Setup-Info?
Afaik its not possible in LFS to see any of these informations, with these anyone is able to rebuild a setup. Or am I missing something?

The setup data is present in the RAF files, so they are already available to anyone. BTW, it's not the complete setup: camber, caster, diff lock, and tyre pressure are missing, to name a few. You can't reverse-engineer a complete setup with it.

Quote from SamH :I agree, releasing the footage would give us a final and conclusive answer.

I seriously doubt if releasing the footage would defuse the conspiracy theories. The desire to believe is so strong that conspirationists will simply raise new doubts ("the footage has been edited, we have proof!"). Or they can shift focus to the many remaining issues. Or as last resort: the fact that there is no clear evidence of the conspiracy only proves how cunning "they" are.
Quote :However, NOT releasing the footage fuels the conspiracy theories - the perimeter fence, that keeps Americans talking about "IF" it happened, so they never reach the inner wall of "WHY" it happened.

Hmmm, interesting remark. This means that not releasing the footage serves a common interest of the conspirationists and of the government.
