ninja: sighs. memory lane :)
libvde: ndim: btw... whenever the driver breaks now, we will say that you told us to do so :p
ndim: Uhmm.... this is someone else typing.
libvde: nope, not really :p
Death_Syn: svn blame
Death_Syn: er
Death_Syn: sorry
udovdh: hello
beerockxs: how can I get a log with logverbose 7 when gdm starts X?
beerockxs: stop gdm and use startx -logverbose 7?
libv: beerockxs: there is also /etc/X11/xinit/xserverrc
beerockxs: libv: thanks!
libv: hrm... on opensuse it is rather more complicated
udovdh: just do: init 3
libv: here you need to put it into args
udovdh: then do the X -logverbose 7
udovdh: ctrl-C
udovdh: and voila
libv: udovdh: :)
udovdh: works even on opensuse?
libv: yup
udovdh: (don't have suse here)
udovdh: be aware: close desktop apps in advance!
libv: on debian xserverrc was very simple and you could just add -logverbose 7 to the one liner in there
Tigerche1: libv: hey there
libv: hi Tigerche1 :)
libv: i'm on a different driver for a few hours... and egbert his tool doesn't care about fonts, so i have to go and figure that one out too (after figuring out a few upstream horrible breakages)
Tigerchen: libv: breakage is bad
libv: yeah, and a few of those is just commits the commiter never even tried to build :(
Tigerchen: uuuuuh
Tigerchen: that's bad
Obscene_CNN: my improved super obsessive compulsive low cpu usage fast r5xx_xaa.c hack http://rafb.net/p/XKrvep62.html
Tigerchen: Obscene_CNN: what does it do?
Obscene_CNN: its just a slightly faster version of the xaa 2d acceleration stuff
Tigerchen: ah
libv: Obscene_CNN: you should keep this as a .diff
libv: Obscene_CNN: git-diff provides this already
Tigerchen: libv: will you be here again tonight?
Obscene_CNN: I will at some point. I need to do some serious cleaning up on it first.
libv: Tigerchen: i will be here for probably the next 4h :)
Tigerchen: libv: if there's anything i can do to help with my two bugs, just hl me
libv: Tigerchen: ok, great :)
Tigerchen: I'll be propabla here till.... 6
dmb: what exactly does full EXA composite mean
marcheu: it means implementing all EXA composite operations, which allow hw accelerated font rendering, shadows, transparency & all
dmb: marcheu: ah, its not drm/dri right?
marcheu: no it-s npt
marcheu: not*
Diablo-D3: I think Im going to celebrate the day fglrx is dead
airlied: dmb: its what radeon is currently growing on its r3xx-render branch
Tigerchen: Diablo-D3: who won't ?
Tigerchen: Diablo-D3: i think even ati will be happy that day
libv: Diablo-D3: yeah, but sadly ATI won't give up without a fight
airlied: it'll never die, but at least ppl won't have to use it.
Diablo-D3: that isnt it
Diablo-D3: I hate closed source drivers
libv: Diablo-D3: you're not alone, there's nothing like good clean and maintainable code
Diablo-D3: well
Diablo-D3: you've heard my rant about nvidia fucking over agp users, right?
Tleilax: have you guys recieved specs for avivo/mpeg etc acceleration?
Diablo-D3: they purposely broke agp on everything but nforce northbridges
Diablo-D3: and refuse to fix it
dmb: libv: yes, i agree
libv: Tleilax: i don't think we can hope for uvd to become public
Diablo-D3: so, nice features like, oh I dunno, HIBERNATION doesnt work
Tleilax: read an ATI employee on phoronix discussing potential legal issues
libv: Tleilax: too much drm entangled
dmb: libv: i'm glad your company stepped up on the effort to produce a driver :D
Diablo-D3: uvd ... universal video decoder?
libv: Diablo-D3: yup
Diablo-D3: I dont want it supported anyhow
Diablo-D3: I use mplayer
dmb: libv: your with suse right?
Diablo-D3: so unless mplayer specifically supports it, its useless on linux
dmb: (novell)
libv: dmb: i'm glad too, i get to play with proper hardware (for a change) and get paid too :)
Diablo-D3: libv: hey
dmb: yup
libv: and i have a desk full of cards
Diablo-D3: whats missing in radeonhd?
libv: but egbert and emmes are always stealing them :((
Diablo-D3: steals one too
Diablo-D3: infact
Diablo-D3: steals two
Diablo-D3: CROSSFIREX! WOO!
libv: Diablo-D3: we have no crossfire yet
libv: Diablo-D3: not sure what tricks drm should learn for that
Diablo-D3: yes well
Diablo-D3: I plan on booting windows
Diablo-D3: just so I can play halflife 2
dmb: wine?
Tleilax: libv, that's a shame =( fglrx doesn't even have particularly good video acceleration
libv: Tleilax: nothing we or amd can change tbh
Diablo-D3: dmb: wine apparently is still flakey with steam
Tleilax: *nods*
Diablo-D3: btw, why the fuck does fglrx still fuck up vsync?
dmb: fgrlx doesn't work very well with doom3 or secondlife (or at least i hope its the driver and not my card)
dmb: hard crashes :D
Diablo-D3: just wants to kick the shit out of ati someday
Tleilax: I was playing with an X1300 in an Xserve and the drivers there spank fglrx pretty hard
Diablo-D3: though AMD seems to have beat me to it
Diablo-D3: Tleilax: with 10.5.1?
Tleilax: 10.4 something
Diablo-D3: 10.5.1 pushed a lot of ati and nvidia driver updates
Diablo-D3: so it should rape it even harder
Tleilax: the video was what I noticed in particular, output was fantastic looking, silky smooth
Diablo-D3: yeah it is
Diablo-D3: even on my ancient powerbook here
Diablo-D3: that has a mobile radeon 9600
Diablo-D3: everything but games rocks pretty hard
Tleilax: I stuck my X1400 running fglrx beside it, both on 1440x900 monitors, no comparison... I haven't tried 8.03 yet though
Diablo-D3: meh
Diablo-D3: you know what sucks?
Diablo-D3: Im still stuck with nvidia
Diablo-D3: I just have to wait until phenoms come out
Diablo-D3: it isnt that far away
Tleilax: *shrug* hard to hate nvidia imo, they were the first to get on board with decent 3D on linux
Tleilax: for a few years they were the only game in town, period
Diablo-D3: bullshit Tleilax
Diablo-D3: bullshit
Diablo-D3: the r200 driver in dri ran circles around nvidia's bullshiut
Diablo-D3: I had a radeon 8500 when radeon 8500s were still popular
Diablo-D3: nvidia was trash then, and its trash now
Tleilax: uhm, I'm talking about before xorg existed
Tleilax: TNT2 days
dmb: xfree86 days!
Tleilax: yeah... if you actually wanted to play any cool games with S3 texture support etc, nvidia was the only game in town
Diablo-D3: s3 texture support sucks
Tleilax: but ut2k3 rocks.
Diablo-D3: why would I enable a feature that degrades texture quality?
marcheu: tnt2 doesn't have s3tc, but please keep trolling
Diablo-D3: also, yes, what marcheu said
Diablo-D3: I believe geforce 2 was the first series that had s3tc
Tleilax: well no one played ut2k3 on a tnt2
Tleilax: and i never said it had s3tc
Tleilax: are you seriously trying to say that nvidia wasn't the first player with good 3D drivers on linux? is that trolling now?
libv: Tigerchen: around?
dmb: libv: any news on that issue?
dmb: vt thingy
Diablo-D3: I'm seriously saying nvidia historically has sucked dick.
Tleilax: hahaha and I'm trolling ;)
libv: dmb: which of the vt switching issues would this be?
marcheu: Tleilax: I wasn't aiming at you in particular, FWIW :)
libv: dmb: ah... the lvds issue, right?
libv: dmb: no, not yet, but i know up which tree i should be barking :)
Tigerchen: libv: sure
Diablo-D3: afk food
dmb: libv: yeh
dmb: libv: also, trying to reproduce that other bug and trying to report it
dmb: where i'll be typing sometimes and the right side of the screen fuzzes, or artifacts flash on the screen as i hit the keys
libv: dmb: ah, this is most likely a linebuffering/memory controller setup issue again
dmb: libv: so its related to the vt thing as well?
dmb: oh
dmb: this was around before the huge commit pool though (as well as the vt issue)
Tleilax: so when you switch to a vt, you save the state of the card, initialize whatever VESA mode it's running at, then redraw? What's responsible for storing the state of all the VTs?
Tleilax: I guess it would be kinda retarded to store VTs in terms of the framebuffer though, just the character buffer is stored eh?
dmb: what happens when you don't use a framebuffer :D
Tleilax: well it is a framebuffer regardless of whether you use radeonfb or whatever, isn't it? linux is "unaware" of that though, eh?
dmb: Tleilax: i'm pretty sure linux uses the native bios console if you don't use a framebuffer
dmb: for example, when i switch to a vt, its using the same font as my bios
libv: Tleilax: you have to save/restore quite a bit of the cards state to be able to return to a VT, whether it is a vga console or vesafb
dmb: libv: vga console is a lot faster then vesafb right?
Diablo-D3: back
libv: dmb: vga console scrolling means adjusting two bytes over IO, vga text is just written as bytes to linear aperture that is available for that... so there is little data that is sent around
libv: dmb: the hardware gets a font table uploaded, and looks up the almost ascii characters in that
dmb: libv: is there a native font table uploaded by the bios if linux doesn't insert one?
dmb: also, where can i read up on this stuff, just for my own curiosities purpose
libv: dmb: the bios does it, linux does it too
libv: there is freevga somewhere, but it is rather incomplete
libv: dmb: and not many people have actually extensively played with vga textmode :)
dmb: libv: is there a way to tell linux not to, and use the native bios font?
libv: dmb: the linux fonttable is pretty standard
libv: dmb: but you would have to make some hacks into the kernel code for this
dmb: oh
dmb: is it bitmap based or something?
Tleilax: heh, I was reading up on VESA... they have support for stereoscopic 3D, but not for specifying arbitrary resolutions =) well concieved!
libv: Tleilax: think back to '94
libv: Tleilax: Virtual Reality...
Tleilax: hehe, yeah, but still... pretty glaring omission
libv: Tleilax: Virtual Reality was a buzzword, it was bling
libv: Tleilax: most people lose track of important things when near something bling
libv: anyway... thanks to Tigerchen, i just fixed what is probably the most clueless bug in our driver so far :)
Diablo-D3: lol
Diablo-D3: what was the bug?
Tigerchen: initialize something in the r500-code with the rv620-value
Diablo-D3: wow that is pretty funny
Diablo-D3: copypasta will always bite you in the ass
Diablo-D3: maybe not today, maybe not tommorrow, but when you least expect it
Tigerchen: yeah "how could that have worked at all"
Tleilax: is there really much point in supporting r5xx and r6xx in the same driver? my understanding is that 6xx doesn't have traditional 2d acceleration at all
Tleilax: which, btw, is pretty damn neat =)
libv: Tleilax: r5xx and rv620+ share a lot of modesetting infrastructure
libv: Tleilax: it makes less sense to share r5xx and anything before it
libv: Tleilax: but then again, our driver is nice and modular, and we can just plug away different callbacks
libv: Tleilax: making it easy, when we don't do stupid things, to keep older devices running just as nicely
Tleilax: gotcha =) didn't mean to suggest you guys don't know what you're doing, just curious
libv: dmb, Tigerchen: are you guys still seeing the restore issue after a clean reboot with this fix?
libv: this could've influenced the dotclock rather heavily, and could cause the colour changes
libv: Tleilax: well, from this bug... i'm no longer sure we do know what we are doing ;p
Tigerchen: libv: *test*
Tleilax: i've looked at the register definitions a bit, hehe, it'd be trivial to pick the wrong one
dmb: i'll check in like an hour, have to finish this network coding hw
libv: ok :)
dmb: select is a bitch to use
Tigerchen: libv: restore issue (blinking stuff) still there sometimes
libv: ok... so unrelated...
libv: Tigerchen: let me first fix the CRTC2 - LVDS issue, maybe this is the same rootcause
libv: digs the m56 out from the mess that is his desk
richiefrich: Diablo-D3: you use this driver too i didnt know
richiefrich: hi dmb
dmb: hey
dmb: radeonhd is a pretty popular driver :D
richiefrich: dmb: yeah looks that way, i just didnt know Diablo-D3 had a card
richiefrich: dmb: thats good though
richiefrich: more ppl using this driver the more features we should see
richiefrich: .me waits for his arm toolchain to finish compiing
Diablo-D3: I dont yet
richiefrich: Diablo-D3: ahh ok
dmb: ok, i'll try the svn
richiefrich: dmb: whats wrong
soadar: I have no framebuffer support from vga=ask through grub bootloader in debian kernel
dmb: richiefrich: i little r5xx bug
richiefrich: dmb: i like the new frambuffer driver uvesafb
dmb: richiefrich: yes, that is really nice
dmb: richiefrich: i can go at almost native resolution
richiefrich: dmb: it doesnt take much ram and it is faster
dmb: right now i use vga console
richiefrich: dmb: i do go native res
richiefrich: 1600x1200
dmb: anyway, brb, testing
richiefrich: ok
dmb: libv: nope, still get the issue
dmb: btw, i guess its a bad idea to copy over the driver while its running
libv: dmb: yeah, for some reason the changed binary is used directly
dmb: yeh, that is weird, i guess its for like 'hotswap' updates for video card drivers in the future or something
airlied: dmb: mv the original aside and then cp the new one in.
airlied: or just rm the original one first might also work
dmb: yeh
Tigerchen: hmm, strange programmers today, are tired at 2 o'clock
libvde: those strange programmers were on their bicycles at 10.00 doing 30kmph over 25kms :p
libvde: i'm sure i'll be better adjusted to doing that several times per week in a few weeks time :)
Erudified: Uphill both ways! =)
Erudified: In the snow! And tropical heat!
Tigerchen: libv: ^^
Erudified: hehe... my license has been suspended for about 3 years now, so I make heavy use of the ol' schwinn mysef
Tigerchen: libv: i'll have to get used to my bike again, but curently i'm not able to hold more than 25 over a longer time
Erudified: you guys have speedometers?
libvde: Erudified: no, but very cold and a hard straight wind straight ahead one way, straight in the back the other way, with a hill in between
Tigerchen: Erudified: sure, but i don't know if it's scurrently adjusted right
libvde: Erudified: no, it broke last century on my old one, and i still haven't found time to dig out a proper new one for the bike i bought last friday
libvde: my trusty old mountainbike broke sunday two weeks ago :(
libvde: frame busted in a place that's impossible to weld
Erudified: I've never really liked riding 10spds
Tigerchen: libv: get one with rpm-display for the feet
libvde: Tigerchen: urgh, my brother has one of those things... rather a lot of batteries and rather a lot of weight
Tigerchen: nope
Erudified: progress marches on
Tigerchen: perhaps you get me wrong
libvde: it's like 4-5 different modules all over the place
Tigerchen: give me 10s to seek it out
libvde: one under the chain, one on the front wheel, then the main module, and a strap to the chest
Tigerchen: nope, it's 1 extra-module like the ne attached to the wheel for the speed
libvde: Tigerchen: i would like to have something which shows elevation changes as well
Tigerchen: this one is attached to the "whateveritiscalledwhereyouputyourfeeton"
libvde: Tigerchen: pedal?
Erudified: I was envisioning a little thing where you entered in your wheel diameter and it had a missing tooth-type sensor attached to the brakepad
libvde: or crank?
Tigerchen: didn't know the english word
libvde: Erudified: apparently, some grossly expensive hub dynamo company has a patent on using a hub dynamo as a highly reliable speedometer
libvde: Schmidt or something
libvde: would be a lot more reliable than those magnets you stick on a spoke
Tigerchen: libvde: have a look at this one: http://sigma-sport.de/de/produkte/bikecomputer/topline_wired/bc1606l/?punkt=features
libvde: and it would be a good use for that single watt that hub dynamos still use today
Tigerchen: libvde: i have never had problems with these
Erudified: I don't think what I'm talking about is a hub dynamo... engine control sytems use missing-tooth sensors to determine engine speed
Erudified: could be wrong though
libvde: Hintergrundbeleuchtung?
libvde: urgh, bad for battery life
Tigerchen: normally it should only be lighted when u press the matching button
libvde: but then... my 1996 cateye had a light too, now that i remember it
Tigerchen: at least my bc 1400 is that way
libvde: right...
libvde: hrm... the only sigma with an altitude meter is a wireless one :(
Erudified: are you guys ze germanz?
libvde: Erudified: belgian living in germany
Tigerchen: Erudified: yes
Erudified: cool place?
libvde: Erudified: yeah, there are actual features to the geography here :p
Erudified: hehehe i hear that, I'm in northern KY, huge corn fiekd
Erudified: KY == kentucky, kinda middle of nowhere, USA
libvde: right, so very flat?
Tigerchen: libvde: where are you living atm?
libvde: Tigerchen: nurnberg :)
Erudified: I've heard germans party their *asses* off
Tigerchen: libvde: well, that's quite a way from here, too bad
libvde: Erudified: only once a week for me... i need half a day to recover each time :(
Erudified: not constantly but when there's a notion to throw a shindig they generally go the whole 9 yards
libvde: Tigerchen: as said, egbert doesn't live that far from you
Erudified: what are the borders like in europe? can you freely go from germany to any other country with no hassles?
libvde: Erudified: within shengen countries, yes
Erudified: shengen? EU?
Tigerchen: Erudified: a bit more
libvde: Erudified: but it's still rather awkward... belgium and germany are direct neighbours and have been part of what became EU almost since the start, yet, when i moved here i had to get my passport replaced in the belgian embassy in berlin ...
libvde: Erudified: so this whole european integration thing is evolving rather awkwardly
Erudified: i've always imagined that being an american in germany would afford ample opportunities for casual fistfighting
Tigerchen: Erudified: http://en.wikipedia.org/wiki/Schengen_Agreement if you're interested
Erudified: cool
libvde: Tigerchen: only one sigma has altitude measurement :(
libvde: Tigerchen: this is too bad because i am starting to enjoy exploring nearby hills and small mountains
Tigerchen: libvde: that's too bad, i always liked them (they survived every rain,/throwing around, ...)
libvde: and i am not too happy about wireless either
Tigerchen: sure
Tigerchen: wouldn't want a wireless one ald
Tigerchen: also
libvde: not for the short distance you need from your front wheel to the bar
Erudified: heh that's interesting... the UK and Ireland only have "police and judicial support" for Shengen? I can only guess what that means hhaha
Tigerchen: Erudified: the island-apes did something special.... again ^^
Erudified: hahahahah island-apes
Erudified: I wanna get it on this racial tension between different breeds of white people
Erudified: here in the USA we only get to bash on people whose skin is a different color than ours, and frankly it's kinda limiting
Erudified: =)
Tigerchen: since we dont bash colored people we have to see for sme other victim
Tigerchen: and british and americans come in quite handy
Erudified: we do what we can!
Tigerchen: i mean: who in his right mind woul have voted for bush again ^^
Erudified: y'know, I'll admit, I voted for him the 1st time
Tigerchen: well everyone has the right to make a mistake, but not to make it twice
Erudified: but that was when he was talking about small government and no nation-building and non-interventionism and his opposition was possibly the hugest hippy of a generation
Erudified: some kind of new sinister suit-and-tie-wearing breed of hippy, not to be trusted! lmao
Erudified: Tigerchen, really the USA as a collective probably isn't that much different than Europe politically - the southern states still have very different values than the northern states, they talk differently, there's a lot of bad blood between states in a lot of places, etc - Bush was a southern president
Tigerchen: well, it won't be possible to make the mistake again, and i surely hope obama makes it
Erudified: it's very diverse... Bush never actually won a popular vote, which ought to restore a bit of your confidence in us!
Tigerchen: like a friend was told: "garmany isnt that somewhere in the united states of europe?"
Tigerchen: Erudified: i have confidence in the us again when you stop playing "word police" (whcih will propably never happen)
Erudified: yeah, we're getting a bit ridiculous, I agree
Tigerchen: i just wonder i anybody still believes that bush went into iraq because of a different reason then to kick saddams ass and get the oil
Erudified: for the vast majority of americans, that would have been good enough
Erudified: "Look - the sumbitch tried to kill my old man. We're gonna git'em! And we're gonna git the oil! Who's with me?! Support the troops!"
Tigerchen: might be... well, i still thin the NATO should have declared a total embargo on the us because of this attack
libvde: pffff...
Erudified: I think Afghanistan was justifiable
Erudified: but yeah, Iraq was unnecessary and stupid
libvde: Fahrrad-Funktionen: Momentangeschwindigkeit (bis 199 km/h)
Tigerchen: looool
Tigerchen: libvde: 100 würd ich ja ncoh akzeptieren
libvde: Erudified: and it ruined whatever was going to be achieved in afghanistan
Erudified: if it can't break the sound barrier, why bother? lol
libvde: Erudified: bicycle functions: current speed: 199kmph
libvde: up to 199kmph even
libvde: if you're coming down a mountain that fast, even hydraulic brakes will not help you anymore :)
Tigerchen: libvde: well, on the tour de france they might crack the 100 down some hills
libvde: Tigerchen: some special recumbents can hit 130 on flat
Erudified: heh, I've done 200kmph on a motorcycle, and there's not a whole lot of good to be said about it
Tigerchen: libvde: I'm taling about "normal people"
Tigerchen: Erudified: i think so, i did 160 when i made my license, and i dont think i want to go faster
libvde: Tigerchen: :) i think this were normal people, just hobby sporters in the us, in a sprint... i think it is on youtube
Erudified: Tigerchen, I've rode a couple bikes that'd do about 160kmph... in first gear... pure insanity
Erudified: hell, even the 600's nowadays are on that level, it's just ridiculous
libvde: Erudified: we're talking human powered things here :)
Tigerchen: yeah, but he said that even on a motorcycle he doesnt want to go 200
Erudified: yeah, but as us americans like to say, if you ain't cheating you ain't trying =)
Erudified: i can't even imagine 100kmph on a bike, but I don't ride a 10spd
Tigerchen: brbr bringing my gfs laptop back to his place
libvde: http://www.youtube.com/watch?v=5V2FgwN_re4
Tigerchen: libvde: that's like the cars going supersonic on these salt-lakes
Tigerchen: nothing near reality
libvde: sure, but still quite cool, i'm happy when i reach 1/3rd of that on flat terrain :)
Tigerchen: ^^ fullack
Tigerchen: i got to a avg of about 30 when i rode to my sailing-club twice a week, but I'm not in training anymore
Tigerchen: university breakes you down ^^
libvde: yeah, here too, i live 1.5km from work, and all i get is a few quick dashes between lights
Tigerchen: i have about 30km to university, and you don't want to ride that distance every day (and especially not when you have to be there at 0800)
libvde: so me and a colleague are now doing longer trips on the weekend (when the weather is mediocre) and a few trips to some old garbage dump site which is turned into a hill with solar panels and which is a nice 50-75m climb
libvde: this is the trip we did this morning, but we intend to do this one at least twice per week
libvde: right, 30 is a bit too much
libvde: especially for a commute
Tigerchen: and if you
libvde: for repetitive weekly fun, it is great, but one way commute, slightly too much
Tigerchen: re sitting on the train that will take you straigt to the place you want to get, it's really hard to stop somewhere and get out
libvde: right
libvde: my brother just bought a brompton for commuting
Tigerchen: he can't be far from work
Tigerchen: that's my current bike: http://www.fahrradhausortrand.de/bilder_optimiert/angebote_maerz/villiger_davida.jpg
libvde: 4km to the main trainstation, 3km from another big trainstation to his main "office" or similar distances to the two universities he is tied to as a doctorate student
libvde: he seems to like his brompton even though he does spend a lot of money on his racing bicycle
libvde: Tigerchen: cool, how is the terrain where you live?
libvde: Tigerchen: because i do not think i would feel comfortable driving on gritt or stones for a long while with a racing bike
Tigerchen: libvde: depends, there are many flat regions, but if you want to torment yourself you could easily go up to the taunus
Tigerchen: libvde: well i bought this bike because i only drove inside ffm at that time, and there's nothing better for streets
libvde: which is why i went for a cross bike now: a dynamics with mixed deore group, front suspension that's always locked out, and hydraulic rimbrakes (this is something i really am very fond of now - well worth the money)
Erudified: hydraulic brakes on a bicycle? I use my foot!
Tigerchen: but if i had the money i would keep the shift and build it to a mountain-bike-frame
libvde: Tigerchen: sure, for streets it is indeed the best solution, but sadly you don't get nice cycling lanes here in this part of .de
libvde: Tigerchen: ah, you mean put the gear on a mountainbike?
libvde: Tigerchen: i had a shimano sora on my now defunct mountainbike :)
Tigerchen: libvde: take the street, the most part of cycling-lanes is not asphalt but like the sidewalk,and that sucks with 7bar on the tires
libvde: 52:11 on 26" with big tires :)
libvde: Tigerchen: right... my colleagues seem to prefer the street too
Tigerchen: libvde: exactly, because i don't want to be in the highest gears when travelling over flat, what gears should i take when going downhill ^^
Erudified: jesus, 7 bar?
libvde: Tigerchen: in .be cycling is much more common and there are really nice cycling lanes
Tigerchen: Erudified: normal on a racing bike
Tigerchen: libvde: i know as are in holland, but what i noticed there: you always get quite string wind directly in the face (and again in the face when you turn and drive back)
libvde: Tigerchen: i used the big gears most of the time, i barely left 52:11 when i was on big flat cycling lanes in .be, unless the wind was too strong or i was too knackered already
libvde: i tend to like lower rpm for pedalling
libvde: but then, i am used to fully flat terrain
Tigerchen: libvde: a pe-teacher who makes triathlon herself told me that it is most efficient to get rpm up to about 80-90
