@Raziel
U can disable atan2 via the argument and see if it helps.
(useATAN = 0)
@hnl_dk
I just proposed a simple test for atan2 alone:
printf("45deg = %lf\n", atan2(1,1) * 180.0/M_PI);
printf("90deg = %lf\n", atan2(1,0) * 180.0/M_PI);
printf("135deg = %lf\n", atan2(1,-1) * 180.0/M_PI);
printf("180deg = %lf\n", atan2(0,-1) * 180.0/M_PI);
printf("-135deg = %lf\n", atan2(-1,-1) * 180.0/M_PI);
printf("-90deg = %lf\n", atan2(-1,0) * 180.0/M_PI);
printf("-45deg = %lf\n", atan2(-1,1) * 180.0/M_PI);

edit : hnl_dk's post below reminded me that iot should be between -180 and 180 degrees, corrected last 3 lines, thanks.

@hnl_dk and raziel
It could be easily verified by compiling the atan2 test program (I would test 7 calls, pairs of args such as:(1,1) (0,1) (-1,1) (-1,0) (-1,-1) (0, -1) and (1, -1).
Compile it vs clib2 and via newlib and check results. I dunnoh how to do it and if it is possble, but if it is: compile vs system math libs as well, but that could be same as newlib (I'm too rusty after such a long time without A1).

@K-L Quote: mtu=1500
Then create the directories ENVARC:RoadShow/tcp
Open NotePad and type 1460, save your text in ENVARC:RoadShow/tcp naming it "mssdflt" (without the quotes of course). Reboot. mtu is for the device driver. Is the mssdflt for tcpip stack to set limit on transfer units? The whole issure reminds me a problem I had with "level-one" router (non wireless) hooked to a dsl modem. PC defaulted to 1500, and the dsl modem had 1492 or something on lan side. It caused non-reliable connection, not dhcp or static connection but pppoe (handled by the router). Going down to 1490 on pc solved the issue. The difference here is that when using static connection the mtu is explicilty set as the default one (probably 1500). when automatic the mtu can be set by the server. That leads to the dhcp client that doesn't support it well or bugged? Wrong mtu should result in bad connection, but not freeze (imho). So according to this logic it is bad mtu handling by dhcp client of Roadshow (overflow or something). Bad mtu negotiation can be blame of the router or Roadshow. I would experiment with 1490 to see if it reliable (broblems should apper pretty fast if they exist). Jack

This one is quite weird one: on Mozilla once I make the window narrower, I get the bottom scrollbar behaving in the following way: the widht of the scroll bar changes constantly. A bit of investigation led to the snow flakes animation being the prime suspect. It's running at the top of the screen and has varying width (imho) that isn't updated when the window gets narrower. a movie showing the stuff is hereJack

Totally agree. A good idea is to make the cpu busy with some cpu-hungry task running at low task pri while playing dvd, let it run for 10-15 minutes at least. Just to make sure the thing is solved. Jack

@Spirantho: Quote: Putting aside the current absence of hardware, it's not a bargain, but not rip off as well. If I was offered, I would really consider this as a broken cpu replacement for my A1.
Personally I'd say it is a bargain - given that the seller could get twice that amount without too much effort, I reckon. [/quote] Isn't this exactly what I said? Throw the abscence of hardware back into the equation: you will find it a bargain As to "twice that amount", there was a ps3 from the batch that was sold at the day of its release, it went on EBay for 15kUS$. Half the price might seem a bargain to some people, to others --- not. I would call fair selling it at price of a new one. Going up as high as twice the price is a rip off. That's my opinion.

I still have a soft spot to the old A500. I had it for 5 years, and got the A1200 because there was a chance to (actually traded in the A500 for A1200). Last time I saw it It had 1MB chip an A590 with 2MB fast and 40MB scsi hd.
Then came A1200 with Mocrobotics expansion card with FPU and 4MB. It's expanded with 68060, 80GB hd,cdrom, cdrw, 64MB ram, prelude, pixel64, pcmcia network card, scandouble+flickerficxer. Still using it on regular basis of early death of my A1, which is the favourite of course. Otherwise A1200 would suffice with playing games and being used with midi.
All are great machines, but A1 is the best!!!

Yeah, there may be a way, but AminetRadio does it at the press of a button and it also automatically saves each mp3 with artist and song title. Just leave it playing over night and you'll have a folder full of mp3s.

With over 450bugs fixed,i really hope it's more stable
The 450 fixes were upto July 05, there have been a lot more since then!
Additionally a lot of issues that have been discovered under the latest OS4beta have also been addressed, which in turn leads to extra stability on the other platforms aswell.
Couldn't resist, a snippet on bugs from fvwm2 man pages (no pun intended): Quote:
BUGS
As of fvwm 2.2 there were exactly 46.144 unidentified bugs. Identified bugs have mostly been fixed, though. Since then 12.25 bugs have been fixed. Assuming that there are at least 10 unidentified bugs for every identified one, that leaves us with 46.144 - 12.25 + 10 * 12.25 = 156.395 unidentified bugs. If we follow this to its logical conclusion we will have an infinite number of unidentified bugs before the number of bugs can start to diminish, at which point the program will be bug-free. Since this is a computer program infinity = 3.4028e+38 if you don't insist on double-precision. At the current rate of bug discovery we should expect to achieve this point in 4.27e+27 years. I guess I better plan on passing this thing on to my children....
Don't despair, keep on the good work  Jack edit: my 100-th post (and made it more readable)

People at work are always impressed that you can save the streams to MP3 in realtime. Something I don't think even WinAmp lets you do.
Not a big deal if you know how to do it. Mplayer can capture stream,. xstreammp3 can do it(play and dump the stream simultaneously, using rexx  ) Xmms un linux can dump the playback as raw pcm (afair), mplayer is capable of dumping pcm as well (on AOS4 probably too). On AOS one can select the "failsave" (afair) AHI audio driver. Probably there's a way to do it with Winamp.... Jack.

Quote:As customers, we all want to know what's going to happen in the future, but we will also turn around and beat developers with the very information they share with us. One of the terms we hit them with is, of course, vaporware.
It is going to be a confession-like post, a long one and hopefully not enturely dull. Amiga scene is very singular speaking marketing-wise. In days of Commodore the marketing of Amiga was scarse and announcement timings were weird. Then (after Commodore banckrupted) appeared several, leading then, companies which seemed to do a good business (I was offline these days and raided through bookshops in my town for AmigaFormat to see what's going on and all the hardware/software buying decicions were based on that info and info looked good ). Not having Amiga-related dealer in my country wasn't fun, but there existed hardware options, some were better (phase5) some were definitely wrong decisions in long term (Ateo products). The hardware existed. Now there's one hell of a vacuum. Everything went wrong when Phase5 died. There were some promising projects that time with nice colored posters. I remeber myself being excited by one called AmiJoe. I contacted them to get some info and the feeling was that an a couple of weeks they would start the production, at least that their answer clearly radiated. Then there was Escena which went into NG Amiga project which became A1 (notice, all during that vacuum period) along with other part of NG Amiga project which is now called Genesi/BPlan. As an owner of A1200 I was naturally into the Escena part of the project and ocassionally found myself in AmigaOne camp when the first vacuum era ended. If I was into standalone-board part of NG Amiga I would have wound up in Morphos camp. Although the very curved path I'm happy that I ended up with AOS4. Now there's vacuum again and the level of anxiety I experince now as an owner of dead A1 is in no way to be compared with the patience before the release of AmigaOne and . Eyetech leftAmiga business. I was unlucky then to fry my A1 CPU. Too many hopes followed, things seemed to be steering even when no anouncements on future hardware were made, it was like being pulled by the nose from time to time. On the other hand a complete lack of info would cause me to end the AmigaOne experience about half a year ago. Instead of this I'm now hanging on every bit of info and trying to refrain myself from spitting sarcasm and ranting in the forums... Quote: How many times have some Amiga developers shared information only to be beaten with it soon after. Miss a date? Don't worry, somebody will bring it up again and again. Your customer quickly turns from your best friend to your worst enemy as soon as anything goes wrong.
So is it best to keep secret and control when information flows to your potential customers or is it better to spam the web with your blog and endless announcements? As my old man says once in a while: "it's a stick with two ends". Announcement keep the heat in the campfire. On the other hand too long waiting times drive people mad. And being Amigan requires being at ( least partly) irrational, correct me if I'm wrong. And that's isn't so bad after all. Happy Chistmas and holidays to every one and lets the new year be full of A1 hardware (software will follow), Jack
