06:34<TrueBrain>"In order to prevent even the appearance of impropriety, my companies policy is that software engineers are to avoid inspecting (so using binaries is OK) open source code that has any kind of viral license. Therefore any open source code I myself author must have a BSD type license."
06:34<TrueBrain>so to come back what I said yesterday: a company cannot force your license which you use in your own time
06:35<@Rubidium>it's not the company that actually enforces that his code can't be GPL
06:35<Alberth>hmm, so I look at GPL code, use that knowledge in closed source code, and now I must publish the closed source? weird
06:36-!-LordAzamath [~rightwing@82.131.16.156.cable.starman.ee] has quit [Quit: ChatZilla 0.9.85 [Firefox 3.5.2/20090729225027]]
06:37<TrueBrain>I think it is a weird story he is giving us ..
06:37<Alberth>lawyers are weird people :p
06:37<Alberth>now who said that FUD doesn't work? :p
06:37<TrueBrain>just the idea that a company could control my personal time .. brr ...
06:38<@Rubidium>and the big problem with lawyers...
06:38<TrueBrain>which leads me to the next question: what to eat ...
06:38<Alberth>actually in Holland, everything you make is owned by your boss, ie you cannot do a great invention just outside the boss' time.
06:38<@Rubidium>... they aren't sure either what would happen in court
06:39<TrueBrain>Alberth: things you do when you are on the clock, yes
06:39<TrueBrain>but when I get home, get comphy, it really is all mine :p
06:39<@Rubidium>Alberth: good reason to start your own company and sell your time to other companies
06:39<TrueBrain>what I do now ... not always the best :p
06:39<TrueBrain>you can have a week with absolutely no work :)
06:39<@Rubidium>TrueBrain: quiche?
06:39-!-Akoz [potatoe@217-151-34.oke1-bras10.adsl.tele2.no] has joined #openttd
06:40<TrueBrain>k, starting my compiles again, which yesterday gave 3 system freezes ... it consumes so much IO, the rest of the applications came to a halt

06:42<Akoz>sounds like something made from me.. :o
06:42<CIA-1>OpenTTD: alberth * r17130 /trunk/src/ai/ai_gui.cpp: -Fix [FS#3099]: Last line of output in the AI debug window did not fit entirely.
06:42<Xaroth>Alberth: Only if you spent time at work to invent it.
06:43<Xaroth>if you did it in your personal time, using personal resources and not using any work-bound knowledge, it's all yours.
06:43<Yexo>Xaroth: if it's only slightl related to your work, you'll have a hard time proving you didn't spend work time on it
06:43<Xaroth>Yexo: yep
06:43<Yexo>exactly, "not using any work-bound knowledge", that's the key point
06:44<TrueBrain>Yexo: for that we have VCSes :)
06:44<Yexo>TrueBrain: those don't prove anything about "not using any work-bound knowledge"
06:46<TrueBrain>no, but they do about the part: "spend work time on it"
06:52<SmatZ>that's not really surprising
06:52<TrueBrain>I hate C++ .. cc1plus tends to consumes 200+ MB of memory :(
06:52<SmatZ>you are paid for work, not for your personal activities ;)
06:56*Rubidium wonders what the boss would think if I weren't to use any information/ideas I gathered outside of working hours
06:57<SmatZ>hehe
06:57<SmatZ>why do they request "good C++ programming skills" when you apply for the job :-)
06:57*Rubidium also wonders why smoking people get paid while smoking, especially in countries where it isn't allowed to smoke at the place you work
06:58<SmatZ>when you wouldn't be supposed to use skills gained outside the job ;)

07:43<Akoz>is there a mode to log all debug messages to file?
07:44<TrueBrain>-d9 > log.file
07:45<Akoz>is it possible to toggle at runtime?
07:45<TrueBrain>pipes? Never
07:45<TrueBrain>I once did program a small thingy that sends all debug stuff over a network
07:45<TrueBrain>is somewhere in the code I believe, commented out
07:46<@Rubidium>TrueBrain: I don't think it's commmented out
07:46<TrueBrain>oh :) Then I wouldn't know how to activate it :p
07:46<TrueBrain>I just know I wrote it for WinCE debugging :p
07:46<Ammler>Akoz: we use tee, so we have both
07:47<Akoz>tee?
07:47<@Rubidium>TrueBrain: openttd -l ip:port
07:47<TrueBrain>Rubidium: ah :)
07:47<@Rubidium>see man openttd ;)
07:49<TrueBrain>SmatZ: not BOOST, but OpenOffice takes very long for python update :p
07:49<Ammler>Akoz: a tool to keep stdout but also have it piped to a file
07:51<Ammler>(./autopilot.tcl | tee -a log)

08:24<OwenS>O_o
08:24<OwenS>LLVM is entirely static libraries
08:24<OwenS>TrueBrain: How big is too big for a dependency? :p
08:24<TrueBrain>15321
08:24<OwenS>...
08:25<TrueBrain>(I wonder what he really wanted to ask :p)
08:25<OwenS>I suppose I should say: Is 7.3MB too big for the AI scripting language? :P
08:25<TrueBrain>LLVM is too big for AI scripting language
08:25<TrueBrain>no questions asked
08:26<OwenS>Shame. Because it could be made hellishly fast.
08:26<TrueBrain>yeah, at what cost :)
08:26<OwenS>Startup time (compilation) and binary size :p
08:26<TrueBrain>not to talk about cross-platform issues
08:27<OwenS>LLVM JIT works on Win32, OS X and Linux for ARM, x86, x86_64; the interpreter runs everywhere
08:27<OwenS>(Well, almost everywhere)
08:27<TrueBrain>also on DS?
08:27<TrueBrain>PSP?
08:27<TrueBrain>WinCE?
08:27<OwenS>OK true :p
08:27<TrueBrain>DOS?
08:28<TrueBrain>(do you want me to go on, or?)
08:28<OwenS>[Does anyone actually use the DOS port? O_o]
08:28<TrueBrain>does it matter? :)
08:28-!-Chris_Booth [~chatzilla@client-86-31-157-92.watf.adsl.virgin.net] has quit [Ping timeout: 480 seconds]
08:31<OwenS>Theres the much more lightweight libJIT
08:31<OwenS>Again probably with platform issues...
08:31<TrueBrain>any and all JITs will have platform issues
08:31<TrueBrain>not a real issue perse, if you allow the JIT to work on some platforms, and not on others
08:32<TrueBrain>but then you need to consider the risks of having a JIT
08:32<TrueBrain>now it will be almost impossible to do anything nasty with an AI
08:32<TrueBrain>you can't access, for example, any disk
08:32<TrueBrain>simply because WE are in command
08:33<TrueBrain>but when youuse a JIT .. the CPU is in command .. can you still guarantee that your disk won't be wiped?
08:33<OwenS>I'd say the codegenerator is in command
08:33<TrueBrain>or what happens when you do 1/0?
08:34<TrueBrain>in other words: the complexity increases dramaticly
08:34<OwenS>Div by zero: Signal handler catches it
08:34<TrueBrain>and the handler needs to know where to resume the real game, while dropping the AI ..
08:34<TrueBrain>I don't even want to go there :p
08:34<TrueBrain>now it is simple, the VM creates an error, and it just follow the chain, which aborts the AI
08:35<TrueBrain>in a VM we are in control. In a JIT we are not.
08:35<OwenS>In my case I'm going to throw a C++ exception, which will cause the code to unwind itself =)
08:39<OwenS>So, in other words, my exception handling system is built right on top of C++'s
08:40<TrueBrain>stupid OpenOffice compile
08:40<TrueBrain>consumes too much of everything
08:41<OwenS>Why is it that two of the biggest open source app projects (Mozilla, OpenOffice) invented their own clone of COM (XPCOM, UNO)? =/
08:41<TrueBrain>why are they both impossible to compile?
08:41<OwenS>Perhaps it's related? :P
08:43<@Rubidium>OwenS: because othe COMs aren't portable enough?
08:44<OwenS>What do they need them for however?
08:46<@Rubidium>don't ask us :)
08:46<OwenS>I suppose OpenOffice has the excuse of embedding the applications inside each other.. but Mozilla?

10:38<OwenS>I think I'm gonna go JavaScript style, i.e, all function calls recieve an implcit this parameter
10:39<TrueBrain>pff .. 3 cc1plus processes using a woppie 1.5 GB total
10:40<welterde>any chance of getting coroutines enabled in noai? or do i have to use generators in some way instead?

12:24<DJNekkid>frosch123: is wagon running cost removed again?
12:25<SmatZ>it seems it works for wagons
12:25<SmatZ>looking at Train::GetRunningCost()
12:25<frosch123>hmm, yes, indeed
12:26<SmatZ>only artic parts are skipped
12:26<DJNekkid>it do work in the 2cc set, but there i did it in a more ... crappy way
12:26<DJNekkid>or atleast, imho, ugly code :)
12:26<DJNekkid>with lots of repitition...
12:27<DJNekkid>but there is the B4 variation at the end, and not in the general callback itself
12:28<frosch123>variable B4 is only valid for the front vehicle, but it does not matter where you query it inside the chain
12:28<frosch123>btw. speed is a word
12:28<frosch123>but maybe your vehicles are not that fast :)
12:29<DJNekkid>but would that matter, as the range is at 0kpm
12:29<DJNekkid>kph even
12:29<DJNekkid>as "everything else" is not 0 ?
12:29<frosch123>256 would also be 0
12:30<frosch123>don't ask me about the unit :)
12:30<DJNekkid>it actually would, but still ...
12:31<DJNekkid>if i used -1 * 0 02 00 B6 82 B4 00 FF 01 B8 00 00 00 B6 00
12:31<frosch123>anyway, I don't think the problem is inside the code you posted :)
12:31<welterde>TrueBrain: regarding coroutines too? (-:
12:31<DJNekkid>at the END of the chain, where B8 and B6 are two different CB36 chains
12:31<TrueBrain>welterde: anything OpenTTD (the game) related
12:32<frosch123>welterde: you have to find a question about the webpage :)
12:32<welterde>ah :D
12:32<DJNekkid>where one of the chains had the running cost for beeing in motion, where the other one dont...
12:32<welterde>TrueBrain: who to ask about that then? ;)
12:33<frosch123>Yexo, but as he is not here, the forums :)
12:33<DJNekkid>but i think i can see a workaround now anyway, as my capacaties are stated elsewhere...
12:33<DJNekkid>but it still require some duplicated code... :(
12:34<frosch123>DJNekkid: as I said, the order of checking variables makes no difference
12:34<DJNekkid>thats what i thought as well, but apparently it do :)

12:39<DJNekkid>is it possible to make a "storage" var2?
12:39<DJNekkid>like ... a constant
12:40<DJNekkid>and i can insert this into several places?
12:40<frosch123>depends when you want to assign it, read it and write it :)
12:40<DJNekkid>when i think about it it can be made quite easily...
12:40<frosch123>:p
12:41<DJNekkid>useing some dummy stuff that never go out of range...

13:10<Xaroth>(I have no clue but i do know the whole 1-typo-fucks-up-everything thing :P )
13:11<TrueBrain>well, movws ax, al with al of 0xFF should give a ax of 0xFFFF .. instead if became 0x00FF :p
13:11<Xaroth>er, I can see the issue there :P
13:11<TrueBrain>the true issue comes when you do as next command: add bx, ax
13:11<TrueBrain>now instead of doing -1, you do +255
13:11<Xaroth>which is not really what you want :P
13:12<TrueBrain>well, if it is not intended, rarely :)
13:12<TrueBrain>a stupid typo, hidden in my way of structuring files .. :)
13:13<TrueBrain>but never again, as it is now part of the regression :p
13:13<Xaroth>it's always the typos that cause the most crap :P
13:14<TrueBrain>and if it wasn't for the test app SmatZ gave me, where it showed up as the 150,000 CPU instruction after start, I would never have found it :)

13:16<Alberth>(07:12:13 PM) TrueBrain: now instead of doing -1, you do +255 <--- I once used a C compiler that translated x-- like that.
13:16<TrueBrain>Alberth: not really useful :)
13:16<TrueBrain>Xaroth: but by the looks, they all did it themselves
13:17<TrueBrain>the movies are done in a really clever way
13:17<Alberth>Not really, further in the project, the standard approach was first to check compiler output rather than bug searching in our program
13:17<Xaroth>TrueBrain: their lip synch thing was a wow factor for the game back in the day
13:17<TrueBrain>Alberth: why not use another compiler?
13:17<Xaroth>heck, most games now don't even have pure lip sync :P
13:18<Alberth>we found more compiler problems than bugs in our program :p
13:18<Alberth>It was a 6809 compiler for a school project
13:18<TrueBrain>bad school project, I say :p
13:18<TrueBrain>Xaroth: hehe, nowedays we have movies :p
13:18<Xaroth>yeh
13:18<OwenS>Hmm... For my language, do I go for sealed classes (I.E. convert them to C structures) which are faster, or unsealed classes, which are basically hashtables? :P
13:19<TrueBrain>the questions you have to ask yourself .. they keep on growing :)
13:19<OwenS>Hmm... perhaps I could do a hybrid aproach? =)
13:19<Alberth>implement both, let the user decide :p
13:20<OwenS>If you specify it with "var" in the class definition, it goes in the struct, else you'll pay for it with the hashtable :p
13:20<DJNekkid>yey frosch123... now it works as it should... it, apparently, were something with the action0 of the particular engine

14:14<TrueBrain>just a hunch .. idea ... feeling .. not sure :p
14:14<Ammler>will that written when compile is done?
14:15<TrueBrain>sometimes, I really wonder about the intelligence of a question
14:15<Ammler>a bit too late ;-)
14:15<TrueBrain>Ammler: finger.openttd.org is updated when the binaries are available (at all the mirrors)
14:16<TrueBrain>as it has been for almost a year :)
14:16<TrueBrain>that is what finger represents: the latest available binaries
14:16<Ammler>hmm, I thought it does also update, if compile failed.
14:17<TrueBrain>nope
14:17<TrueBrain>finger, as it should, represents the actual latest available binaries
14:17<TrueBrain>but then again, the compile never failed
14:17<TrueBrain>(as failure would mean that even the source packages were not created)
14:17<Ammler>it did once this year and finger updated
14:17<Ammler>once I know of.
14:17<TrueBrain>the CF hasn't failed since 2005
14:18<TrueBrain>March 2005 .. a good month :)
14:18<Ammler>it is around 2-3 months ago, at least windows bins weren't available.
14:18<TrueBrain>LOL! Yes, that means that CF failed, that the windows binaries failed
14:18<TrueBrain>the whole world dies when that happens
14:19<Ammler>yes, it does, the world is MS
14:19<TrueBrain>my mistake, really, you are absolutely right
14:19<TrueBrain>CF fails when it fails to produce windows binaries
14:19<Ammler>thanks :-P
14:19<TrueBrain>[20:15] <TrueBrain> sometimes, I really wonder about the intelligence of a question <- it is not only the questions I now worry about :)
14:20<TrueBrain>Ammler: the CF couldn't care less if one target fails. If multiple fail, it starts to worry .. but that never happened :)
14:20<@Rubidium>has the compile farm generated binaries, yes? Then the compile farm didn't fail and updating finger is fine
14:20<TrueBrain>Rubidium: strictly seen he even considered the log of a failure enough to publish itself :p

14:33<TrueBrain>it is written for me
14:33<TrueBrain>I assumed it was equal to a 0x12 .. I was wrong :p
14:33<frosch123>why mode is that?
14:33<Tefad>oh, you're doing wonky crap with dune still?
14:33<TrueBrain>320x200x16 (EGA,VGA)
14:34<TrueBrain>(x16 as in: 16 colours, not 16bpp :p)
14:34<frosch123>does it work the same as 640x350x16 ?
14:34<frosch123>oh right, 640x350x4 :)
14:36<frosch123>well, you set in some register which bits you want to read/write
14:37<SmatZ>TrueBrain: reading by nibbles doesn't work?
14:37<TrueBrain>lol :) frosch123: the video screen is written at 0xa0000 .. I ened to read it to represent to my SDL screen :p
14:37<TrueBrain>it seems to be 2 paged memory
14:38<SmatZ>or is it that interleaved XMODE?
14:38<Tefad>intend?
14:38<Tefad>need?
14:38<frosch123>well, 640x350x4 is basically monochrome, with 8 pixels per byte.
14:38<OwenS>It's not one of those funky modes where every other row is on a different page is it?
14:38<frosch123>additionally you have some register where you can mask the 'planes' you want to write
14:39<OwenS>I know you could do some crazy optimizations with the VGA state machine
14:42<frosch123>port 3C4, 3CE, 3CF, 3C5 seem to be the important ones
14:42<TrueBrain>frosch123: again, I am trying to read from memory :)
14:42<TrueBrain>not to use hardware to access data :p
14:42<TrueBrain>(as I am the hardware :p)
14:42<SmatZ>TrueBrain: what exactly is your problem? wrong palette, or wrong order of pixels, interleaved data... ?
14:42<frosch123>yes, and you have to switch memory bases on those registers
14:43<TrueBrain>SmatZ: data is cropped on the first 50 lines or so
14:43<frosch123>but it is not like a page switch, but you can also access multiple pages at the same time, and write the same stuff into them

15:10<TrueBrain>I am flying blind, guessing around
15:10<TrueBrain>doing with the small information I can find
15:10<frosch123>TrueBrain: because 640x350 / 8 is about 64 kB
15:11<frosch123>hmm, no :p
15:11<TrueBrain>ah
15:11<TrueBrain>other modes .. that can be a good enoguh reason
15:11<TrueBrain>@calc 640 * 350 / 4
15:11<@DorpsGek>TrueBrain: 56000
15:11<TrueBrain>almost :p
15:11<TrueBrain>@calc 640 * 400 / 4
15:11<@DorpsGek>TrueBrain: 64000
15:11<TrueBrain>:p
15:11<frosch123>but it is 8 pixels per byte
15:11<frosch123>so only the half
15:11<TrueBrain>hmm .. true
15:11<@petern>monochrome?
15:12<TrueBrain>so it only needs 32k
15:12<@petern>oh, no
15:12<@petern>it's 'paged' or whatever they called it
15:12<TrueBrain>but okay ... I need to figure out a clever way to emulate this :)
15:12<@petern>640 * 350 @ 16 colours, is 112KB
15:13*petern goes back to sleep
15:13<frosch123>TrueBrain: there are also video pages !
15:13<frosch123>that results in 64kB
15:17<TrueBrain>I give up on this video mode .. impossible shit :p
15:19<frosch123>make it monochrome and pick one of the 4 planes :p
15:19<TrueBrain>I just did :p
15:19<TrueBrain>but .. it doesn't animate
15:19<TrueBrain>and I don't know why :(
15:20<frosch123>maybe it read back the data to decide for the next?
15:20<frosch123>or is it palette animation?
15:20<TrueBrain>I don't read palette changes ..
15:20<@petern>mmm, ega palette
15:20<TrueBrain>and I don't read any waiting on anything ..
15:21<frosch123>16 out of 64 colours :p
15:22<Alberth>double buffering?
15:22<@petern>frosch123, that's the one :D

15:31<OwenS>OK... why can't I call the function "as_checkpoint(i8*)" with a [2 x i8]*?
15:32<Eddi|zuHause>i only remember when my father ran sokoban on a colour monitor for the first time, and went like "urgs... it's pink!"
15:32<TrueBrain>the 4 colours on a CGA ...
15:32<Tefad>most horrible ever
15:32<Eddi|zuHause>but that was way before i knew what CGA and VGA is
15:32<TrueBrain>better than green and black :s
15:33<frosch123>yeah, you can somehow pick different itensities, but it stays black, cyan, magenta and white
15:33<Tefad>wasn't there a second mode that did green and orange
15:33<OwenS>Wasn't there a yellow in there which the monitors converted to brown?
15:33<TrueBrain>there are 2 palettes you could select
15:33<Eddi|zuHause>afair CGA had 4 modes
15:34<TrueBrain>both could go in high and low intensity
15:34<Eddi|zuHause>each with 4 out of 16 colours

15:37<Eddi|zuHause>the first computer i can actually remember already had VGA
15:37<frosch123>hmm, seems like you can choose green/red/yellow, cyan/magenta/white or cyan/red/white. together with a fourth arbitrary choosable
15:38<frosch123>typically balck
15:38<Eddi|zuHause>and we played civ all day long...
15:38<SmatZ>:)
15:38<SmatZ>quite soon after I started playing civ I found a way how to edit savegames
15:38<Eddi|zuHause>and sim city
15:39<Eddi|zuHause>and monkey island
15:39<SmatZ>so it spoiled it for me quite a bit
15:39<+glx>at least VGA was standard
15:39*SmatZ never played monkey island
15:39<SmatZ>we had VGA computer home since 1991...
15:39<Eddi|zuHause>it was totally awesome...
15:39<frosch123>haha, simcity with FUNDS and earthquake after doing it too often :p
15:39<SmatZ>hehe
15:40<Eddi|zuHause>we played the "sword fights" pver amd pver agaom :)

15:40<SmatZ>ah, thanks TrueBrain :)
15:40<+glx>my brain failed to decipher it
15:40<frosch123>yeah, stunts!

15:41<SmatZ>hehe
15:41<Eddi|zuHause>just move all right hand characters one to the side :p
15:41<SmatZ>I planned to once code game like stunts, but better
15:41<frosch123>and then too fast in the last corner and hit the finish :s
15:41<SmatZ>mmm OpenStunts
15:41<+glx>I still have it on a disk

15:42<SmatZ>:)
15:42<Eddi|zuHause>stunts was that car racing game where you could build your own route?
15:43<SmatZ>yeah
15:43<OwenS>It works when you obey your calling convention! :P
15:43<frosch123>and where the f1 car was the only one, which was fast enough to successfully jump after one piece of road
15:44<+glx>ML was very slow :)
15:44<TrueBrain>SmatZ: well, if you implement EXEC in my emu, it should work :)
15:44<Eddi|zuHause>where you could cheat by just going around the fomosh line and the penalty was way less than the time it took to actually complete the round?
15:44<+glx>right
15:45<SmatZ>TrueBrain: isn't exec simply doing what you do with the original image?

15:46<OwenS>(Well, I'm assuming EXEC is more like Win32 CreateProcess than Unix exec(2))
15:46<TrueBrain>both not really related to DOS EXEC
15:47<OwenS>More like however :p
15:47<OwenS>As in, DOS Exec doesn't replace the existing process image; it loads the new one and starts executing it; when it finishes, it returns from exec?
15:47<TrueBrain>in DOS, things are much more simplified
15:47<TrueBrain>but there are a few thingies .. which are tricky

16:53<TrueBrain>OwenS: that part is in the opcode, easy to decode
16:53<SmatZ>then there is 2B of imm16

17:08<SmatZ>well, if your assembler understands r1-r8, feel free to use them instead of rax, rcx, ...
17:08<SmatZ>(hmm maybe it starts at r0
17:08<SmatZ>I am used to the "old" naming
17:08<OwenS>r0-r7 are the new regs, but I still have to remember that %rdi is param # 1
17:08<SmatZ>hmm weird assembler you have
17:09<OwenS>x86_64 has 16 regs, rax -> rsp; r0 -> r7
17:09<SmatZ>nasm uses rax-rsp, r8-r15
17:09<OwenS>Oh crap yeah :p
17:09<SmatZ>while maybe r0-r7 is mapped to rax-rsp
17:09<OwenS>Still, it doesn't help since the numbers would jump all over :P
17:09<SmatZ>:)
17:10<OwenS>I'd personally be quite happy if x86 got took out back and shot
17:10<SmatZ>you can %define mr0 rdi ...
17:10<SmatZ>not really possible, you know ;)
17:10<SmatZ>with MMX/SSE/FPU you are using numbered registers
17:10<OwenS>Something RISC would be so much nicer. CISC easier to program in assembly my arse
17:11<SmatZ>but they are not general purpose...
17:11<Tefad>x86 isn't going anywhere any time soon
17:11<OwenS>Then I use %rdi, forgetting it's %mr0, and wonder WTF is happening :P
17:11<SmatZ>hehe
17:11<SmatZ>use only mr then :)
17:12<OwenS>The only nice to program CISC arch I know is m68k. And thats because it's nicely orthagonal
17:12*SmatZ knows only x86 and several PICs... and IA64 a bit
17:12<OwenS>I like the PICs... nice and simple
17:13<SmatZ>yeah :)
17:13<OwenS>Propeller is bloody awesome also
17:13<OwenS>Not only do you get 8 80Mhz (20MIPS) cores, but they have a lovely instruction set also
17:13<SmatZ>hehe
17:14<OwenS>I'll admit it's a bit funny... each core has 2kb private local RAM which acts as both it's registers, fast RAM and program store...
17:14<TrueBrain>Reg2/Mem = Reg1 IMUL Imm <- SmatZ: I got that right, not?

17:47<SmatZ>quite simple one
17:47<SmatZ>compared to enter (C8 ?) with two imm8 and strange behaviour
17:47<OwenS>It's equivilant to MOV xSP, xBP; POP xBP

17:49<OwenS>SmatZ: Enter is C8, and it's C8 iw ib :p
17:50<OwenS>And SmatZ, I agree, ENTER is convoluted and probably very very slow

17:56<OwenS>You'll be delighted to know that my processor design's enter is much simpler :p
17:57<OwenS>push fp; sub sp, r0, N, sp would be the equivilant due to my slightly crazy 4 operand instruction format :p

17:57<SmatZ>the imm8 part is ignored

19:08<SmatZ>why would it read the flags
19:08<SmatZ>*pop
19:08<SmatZ>and never test it
19:09<TrueBrain>no idea ... it later on pushed it back on the stack
19:09<TrueBrain>after which I lose track of it
19:11<TrueBrain>hmm .. DOSBox always runs in 386 .. there is no 286 mode
19:11<TrueBrain>so he is of no use to me :p
19:11<TrueBrain>SmatZ: I can't seem to find any pushf which it uses to check for 286/386 .. :(
19:12<TrueBrain>okay, I take that back ..
19:12<TrueBrain>http://paste.openttd.org/191162
19:13<TrueBrain>(the last call is to code containing 0x66 :p)
19:13<SmatZ>1238:0000002C pop ax
19:13<SmatZ>1238:0000002D and ax,7000
19:14<SmatZ>1238:00000030 je 0000006A ($+38)
19:14<SmatZ>I think it's pretty clear
19:14<TrueBrain>hmmm ...
19:14<TrueBrain>yup
19:14<SmatZ>that jump should be taken
19:14<TrueBrain>somehow the flags were activated :p
19:14<oskari89>Hmmm. r17141 allows higher sound quality? :)
19:14<oskari89>On SFX?
19:14<OwenS>Interesting they used and rather than test
19:14<SmatZ>yeah :)
19:15<oskari89>And as well as .grf additional sounds @ better quality?
19:15<TrueBrain>7 .. that is 1 + 2 + 4
19:15<TrueBrain>so iopl and nt
19:15<SmatZ>no sh*y
19:15<SmatZ>t
19:15<SmatZ>...
19:15<OwenS>wtf... jmp short 0000006F ... aka jump to the immediately following instruction!
19:15<TrueBrain>OwenS: read careful
19:15*xmakina releases JAMI to the wild
19:15<SmatZ>OwenS: :-p
19:15<TrueBrain>I never ever set iopl to 3 :(
19:16<TrueBrain>omg ...
19:16<OwenS>oh lol
19:16<SmatZ>TrueBrain: it probably does some "mov ax, 0xffff; push ax; popf; pushf; pop ax"
19:16<TrueBrain>SmatZ: http://paste.openttd.org/191163 <- the lines above that
19:16<SmatZ>TrueBrain: :-p
19:16<TrueBrain>so that test ALWAYS succeeds
19:16<TrueBrain>DAH
19:16<OwenS>I thought you did the masking in pushf?
19:17<SmatZ>NO
19:17<SmatZ>it should be ZERO
19:17<SmatZ>if you are emulating 286
19:17<TrueBrain>lol
19:17<TrueBrain>so a 286 refuses those flags?
19:17<TrueBrain>hahaha
19:17<SmatZ>.......
19:17<TrueBrain>cool :)
19:17<OwenS>Unimplemented flags are forced zeros normally :p
19:17<OwenS>Saves silicon :p
19:17<TrueBrain>I didn't expect it to react at all on it, just pipe it through the register ..
19:17<SmatZ>[00:29:58] <SmatZ> 8086 sets 4 highest bits to 1
19:17<SmatZ>[00:30:08] <SmatZ> 80286 tests the always to 0
19:17<SmatZ>[00:30:12] <SmatZ> try that
19:17<SmatZ>[00:30:23] <SmatZ> when emulating PUSHF
19:17<TrueBrain>SmatZ: how should I know it FORCES that :)
19:18<SmatZ>what else could I say....
19:18<SmatZ>*tests -> sets...
19:18<TrueBrain>see, there it went wrong :)
19:18<OwenS>It appears pastebins still being spammed =/

19:25<Markk>Fastet cable in sweden I think
19:25<OwenS>Who by? I know more than I ever intended to about Swedish broadband thanks to a swedish friend :p
19:25<OwenS>The best in the UK is Virgin's 50/5 cable package
19:26<Markk>:D
19:26<Markk>Mkay
19:26<Markk>Don't you have fibre over there?
19:26<TrueBrain>SmatZ: I am already at test 7a of 12!! :)
19:27<TrueBrain>btw, INT16:00 and INT16:01 work VERY different then documented :p
19:27<SmatZ>TrueBrain: are you sure?
19:27<TrueBrain>yup
19:27<TrueBrain>double checked with DOSBox
19:27<SmatZ>maybe it's INT16:10:00 or so?
19:27<OwenS>Markk: Nope. Virgin's is FTTC (Fiber to the cabinet - which is about 10m from my housel), BT are testing FTTP (Fiber to the pedestal - I dunno what they're using for the last mile)
19:28<TrueBrain>DOSBox keeps on acting like a key is pressed with 16:01
19:28<Markk>Okey :P
19:28<TrueBrain>which is what checkit expects
19:28<@Rubidium>OwenS: FTTC isn't Fibre to the CPU?
19:28<Markk>Vi have ADSL, Cable (Some houses) and Fibre (Ethernet from the switch in the house I think).
19:29<Markk>We*
19:29<OwenS>Rubidium: Thats a rather absurd statement until we get optical chips :P
19:29<SmatZ>TrueBrain: 16:01 - key is pressed -> ZF=0, AX=keycode; else ZF=1
19:29<Markk>Haha
19:29<Markk>Fibre directly to the CPU <3
19:29<TrueBrain>SmatZ: yup, DOSBox is sending a constant AX=0100
19:29<SmatZ>interesting
19:29<OwenS>My swedish friend has BBB fiber I think
19:30<Markk>Okey :)
19:30<TrueBrain>SmatZ: hmm .. or maybe I fucked up ZF ..
19:30<Markk>BBB (Bredbandsbolaget, lit. Broadbandcompany) is now owned by Telenor
19:30<TrueBrain>ZF = 0 is pressed? That might be the thing I failed to realise :p
19:30<TrueBrain>hehehehehehe
19:30<SmatZ>:-p
19:31<SmatZ>the failure is often between the computer and chair ;)
19:31<TrueBrain>now it wants 13:8 from me ...
19:31<TrueBrain>which is XT
19:31<OwenS>Markk: I thought that was the case. What did I say about knowing more about Swedish broadband than I ever intended to learn? :p
19:31<TrueBrain>so I just ignore it :p

19:37<@petern>no
19:38<@petern>just that until the sample rate converter is improved, it will suck for 11025Hz samples

19:54<TrueBrain>SmatZ: I can't go left or right (those buttons don't work :(), so I can't navigate to test and benchmark :(
19:54<SmatZ>XTs had 4 floppys
19:54<SmatZ>ATs had 2xfloppy + 2xHDD

19:55<SmatZ>:(
19:55<OwenS>SmatZ: The main differences were CPU (8088 vs 80286) and bus (8-bit ISA "XT Bus" vs 16-bit ISA "AT Bus")

19:59<SmatZ>I would expect some deeper difference
20:00<OwenS>The XT 286 looks like a cheapo they produced because it was cheaper to make XTs with 286s than 8088s (economy of scale and all)

20:08<Eddi|zuHause>what's actually so bad about it?
20:08<OwenS>Rather a dodgy bus as well from a signal integrity stand point
20:08<SmatZ>it's looooooooong
20:08<OwenS>Running out the processor bus over 3 cards = not smart
20:08*SmatZ doesn't remember details about the way it works
20:08<SmatZ>like
20:09<OwenS>SmatZ: It's the bus you'd get if you ran a 486 memory bus out over an edge connector. It's an ugly hack
20:09<SmatZ>parts of the bus work at 8MHz (ISA part), and the second part works at... xxx MHz?
20:09<Eddi|zuHause>yes... it's long... but that doesn't explain anything... my first graphics card and my first sound card were extremely long
20:10<SmatZ>well, from my few user experiences, it was hard to make the cards seated
20:10<OwenS>SmatZ: The ISA part is 8mhz and handles interrupts and IO ports. The VLB part handles memory and runs at processor clock. It's pins are directly tied to the processor which isn't designed to drive signals across 3 cards
20:10<SmatZ>when it wasn't perfectly fit, computer didn't boot up
20:10<SmatZ>(start at all)
20:10<SmatZ>OwenS: interesting :)
20:11<+glx>of course how can you perfectly seat a card across 2 connectors?
20:11<SmatZ>I had hard times making one computer with VLB run
20:11<SmatZ>when those cards weren't perfectly seated, it didn't start
20:11<SmatZ>and it was extremely hard to make them seated...
20:11<SmatZ>but maybe it was just my bad luck :)
20:12<Eddi|zuHause>i vaguely remember some computer magazine's review stating something like "the VLB supports 2 cards at 33MHz and 1 card at 50MHz"

20:26<+glx>OwenS: I started with suse 7.0
20:26<Eddi|zuHause>i didn't use boot disks (usually). i created a batch file where i could replace autoexec.bat/config.sys and then reboot
20:26<TrueBrain>things to do for tomorrow: move interrupt shit to places DOSBox has them too .. allowing even easier cpulog compares :)
20:26<OwenS>glx: I think I tried SuSE first and it failed to netinstall so I burnt a Ubuntu disk... didn't work so I burnt a Debian disk... worked :p
20:27<OwenS>Sorry, it wasn't sound that was broken; it was networking
20:27<OwenS>I didn't test sound as I didn't have any ot play :p
20:27<TrueBrain>for now, I wish you all a good night. SmatZ: thanks again for all your help and insight, couldn't have done it without you :) The rest: thanks for the support ;)
20:28<Eddi|zuHause>i remember my first linux installation didn't run well either...
20:28<Eddi|zuHause>i gave up on it, because i had no internet back then
20:28<OwenS>I think I tried Mandriva as well and that didn't work. I was surprisingly persistent
20:29<+glx>I never had problems with mandriva
20:29<OwenS>I somehow managed to end up with an XVWM (?) install with just Firefox :p
20:30<Eddi|zuHause>well, my demands at a linux installation were that it ran well enough so i could scrap everything windows related...
20:30<Eddi|zuHause>i don't want to dual boot
20:30<Eddi|zuHause>actually, i don't want to boot
20:30<OwenS>I didn't double boot. I threw away Windows :p
20:31<+glx>I have dual boot but I always run windows :)
20:31<+glx>when I need linux I start a VM
20:31<OwenS>I always recomend that to switchers because it removes the temptation to be lazy and boot Windows :p
20:32<OwenS>My switch determination may have been related to the fact that MS had recently announced that XP x64 would only be available as an OEM product with x64 processors - very very irritating when you had been running the RC2...

21:33<Zantor>anyone here?
21:33<Eddi|zuHause>no
21:33<Zantor>lol
21:34<Zantor>hi Eddi; long time
21:34<Zantor>I have a couple questions
21:34<Eddi|zuHause>there is nobody here at 3:33
21:34<Zantor>it's 8:34 for me :P
21:34<Eddi|zuHause>yes. but the world does not revolve around you
21:34<Zantor>true
21:34<Zantor>my questions are about the coop server
21:35<Eddi|zuHause>then maybe you should ask them in the coop channel
21:35<Zantor>that channel is dormant

21:35<Eddi|zuHause>well, that may be because of the time.
21:35<Zantor>and that's because most of the OTTD folk are from Europe, not America :P
21:36<Eddi|zuHause>well, then you know what to do.
21:36<Zantor>clarify, please; I can think of several things to do
21:36<Eddi|zuHause>if you don't know, i cannot help you.
21:37<Zantor>can I host a private coop game?
21:37<Zantor>heh that'
21:37<Zantor>is something I could ask the wiki lol
21:38<KenjiE20|LT>there's nothing special about the coop server, that makes it a coop server
21:38<Eddi|zuHause>why would that be any different from any other network game?
21:38<KenjiE20|LT>only the players
