From: "Paul N. Lee" Subject: Fractal Census 2000 Date: 01 Apr 2000 23:26:49 -0600 Greetings, It has been about two weeks since the request for the "Fractal Census" was made, and still receiving an occasional email. I have been compiling this information into a Microsoft Excel spreadsheet, and was only entering the basic stats that was requested. But, decided to expand with additional information (web sites, email addresses, physical addresses, telephone numbers, birthdates, spouses and family members, etc.). It has gotten so large, that it now resembles a small database. I have only taken six of the key fields: Names Various Products Used Qty. Best or Most Used Email Addresses Web Sites to use in the creation of a web page: http://home.att.net/~Paul.N.Lee/Fractal_Census.html This is not the completed census data, which will take a few more hours (or may be days) to finish. But I thought I would publish what I have gathered so for. If someone finds the information for them inaccurate or incomplete, then please reply to the following email address: MAILTO:ABPF_Bot@hotmail.com Sincerely, P.N.L. http://www.fractalus.com/cgi-bin/theway?ring=fractals&id=43&go Thanks for using Fractdev, The Fractint Developer's Discussion List Post Message: fractdev@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractdev" ------------------------------------------------------------------------------- From: "Damien M.

I am trying to simplify his suggestions, which use the XFRACT define whenever the Xfractint prompts are different from the Fractint prompts. I created a mechanism a long time ago for defines like #ifndef XFRACT #define UPARR "\x18" #define DNARR "\x19" #define RTARR "\x1A" #define LTARR "\x1B" #else #define UPARR "K" #define DNARR "J" #define RTARR "L" #define LTARR "H" #endif These were meant to be used like this: static FCODE instr1[] = {"Use " UPARR " and " DNARR " to select values to change"}; but are actually used like this: #ifndef XFRACT static FCODE instr1[] = {"Use " UPARR " and " DNARR " to select values to change"}; #else /* Some compilers don't accept "a" "b", so we have to fill in UPARR ourself. */ static char far instr1[] = {"Use up(K) and down(J) to select values to change"}; #endif Note the comment. Do I still have to worry about compilers that don't support string concatination like this: printf("hello ""world\n"); The GCC compiler supports it. The reason I want to do this is that I am on a campaign to eliminate the XFRACT define whenever possible. Any ANSI-compatible compiler, including BSD and Linux GNU C compiler, should be OK.

Paul, I'm well aware that my address shows up in lots of places on the web. The 2600 FAQ lists it for a rather interesting reason, I think. :-) Usually I ask them all to be removed, just as I asked you. I've discovered that a fair bit of spam comes from web site harvesting, so that's why I ask. I doubt I'll eliminate all of it, but I sure cut out most of the spam sent to ifl@fractalus.com when I removed it from the IFL pages. So, removing as many as I can helps. Now that I think about it, though, I don't recall submitting information to your fractal census. Why am I listed at all? I never thought for a moment you would personally identify all the participants, either. Certainly when I think of "census" I don't think of "directory listing". Damien M.

I knew that, but I needed someone to give me permission :-) This makes a much cleaner way to do the platform-specific user interface via defines with strings like: "To get help press"FK_F1 Of course this will be moot when we do the GUI, but for now it is useful.

We need to make a define that allows the DOS function key prompts to be used with Xfravtint if appropriate. Thanks to Scott Boyd for helping with this patch.

The shift-1 etc. keys still work, but so do the function keys, the cursor keys, and the pageup etc. keys. However the "arrow" characters aren't the same, so the character set is different from the DOS character set, so some of the fractint.h defines still need to be different from Linux. I suggest you grab my patch 10 sources and look at the defines I created in fractint.h (FK_F1 etc.). We will need to set up a system to use the correct defines. BTW I saw a bug - when one cursor's around the fractal type list, sometimes the type name is written too far to the right, I need to look into this.

Does this happen to you only in Xfractint? If so, it might be the terminal session you're using. What terminal session are you using? I have discovered what might be a bug in both Xfractint 20.0.7 and 20.0.10. In the fractal-type list, select mandelcloud. Just leave the next parameter screen as is and press Enter.

Yes, that's a bug. The cellular type does this also, when you press the space bar twice. I tried to find my list of known Xfractint problems to see if this was on it, but it appears to be lost in the mists of time. I'll start a new list. That way I'm sure to find the old one. (later) Yep, I found it while looking for something to respond to a different email. The type=mandelcloud isn't on it.

I am using Linux-Mandrake 6.1 with kernel 2.0.13 Bug #1 only happens in Xfractint 20.0.10. Bug #2 happens in both Xfractint 3.11 (Fractint 20.0.7) and Xfractint 20.0.10. 1: When ever I press Shift-2 (or '@') Xfractint shuts down. (This keypress works OK in Xfractint 3.11 (aka 20.0.7)). 2: Start Xfractint and draw the default fractal. Go back to the main menu Shell to Linux, then type exit to get back to Xfractint. "Press operation key, or to return to Main Menu" will be messed up. (displayed as garbage characters) Press Esc to return to main menu Press 't' - Xfractint will shut down. Or press 'x' and change a parameter, then press 'Enter' - Xfractint will shut down. Other menu keys will also cause Xfractint to shut down, sometimes immediately, sometimes within 2-3 keypresses. I thought this might be something wrong with my computer, so I re-booted into Linux and KDE. Still encountered the two bugs. I also tried the above steps while at the prompt (running Xfractint in diskvideo mode). Xfractint would shut down, and also print "Segmentation fault" as the error message to the screen.

Yes, Allegro is very portable, and as you said it has additional stuff like sound we can use. It is meant for game programmers, but even though we don't need it all, we can use it to good advantage. > The svgalib package has specific video drivers (not VESA) which appears to > be very limiting. I didn't realize it wasn't VESA. That about rules it out IMHO. Console graphics have to be VESA or we're dead. Although VESA support for the higher resolutions is problematic on some boards these days ... > OTOH, Allegro can use FreeBE/AF, a low level video driver > interface with all the features of VESA 3.0. That sounds good. > Are there any other packages we should look at? Are there other > considerations? I think that's about it for non-X operation. Going this route is just to get us permanently into a 32 bit platform. The non-graphics console itself will be getting more rare. However I still think this would be a good step for us even if just a transition. And I'll bet the console will be with us for a while yet. Does Allegro have an X incarnation that can run in an Xterm? The other relevant packages would be portable GUIs. The main choices are WxWindows and GTK toolkit. But you don't have to worry about that just yet. I think making a simple-minded port of the DOS Fractint (maybe the float-only version) to djgpp/Linux would be a good step, and not impossibly hard. These should be maintained in synch with Xfractint, but leave the medium model fractint behind. Once accomplished, there are all kinds of global cleanup/restructuring/rearchitecting that could be done. I hope we can make use of some of Rich's X massage work. I have two more Kalman filter classes, this Thursday and next, then I hope I can free up some time for this. The perpetual dream :-) BTW Kalman filters are amazing. A Kalman filter is an algorithm for taking measurements on the fly to calculate a state vector (as in position and velocity of a spacecraft), but it is smart enough to keep track of how good the measurements are, and to use the better ones more, as well as keeping track of how good it's current estimate of the state is, and factor that in along with the measurements. This is, quite literally, rocket science :-). Wonderful for orbit determination software.

IIRC, there are problems running real-mode VESA drivers in protected-mode Linux. svgalib and X are Linux's answers to VESA. About running Allegro in an xterm: xterm is more or less limited to displaying text. I've displayed graphics in xterms by using a small font and displaying text, but this is slow and not recommended.

Once you tie yourself to a particular package -- even one that claims to be portable and I've looked at allegro and its not bad -- you also tie yourself to its weaknesses. Please don't design in another round of dependency weaknesses (like our current dependency on DOS/VGA specifics), or we'll just have to fight this battle again at some later date. This was my intention behind the driver abstraction that I massaged into the code. It is not dependent on anything specifically, it merely provides abstract function. -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com Thanks for using Fractdev, The Fractint Developer's Discussion List Post Message: fractdev@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractdev" ------------------------------------------------------------------------------- From: Phil McRevis Subject: Re: Allegro Graphics Package Date: 18 Apr 2000 11:41:08 -0600 You really don't want to try and do graphics in an xterm! Xterm is not meant for that! Its for text! Unless you intend to provide a text-driver a la XaoS, I would advise forgetting completely about anything running in an xterm. One of the biggest kludges in xfractint right now is that you *must* run it in an xterm and the code has all this crap littered everywhere to deal with both curses *and* Xlib! All that curses code needs to be removed and text I/O should be done with xlib. If that approach had been taken originally, the xfractint code would be much simpler and would support the PC key mappings better. -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com Thanks for using Fractdev, The Fractint Developer's Discussion List Post Message: fractdev@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractdev" ------------------------------------------------------------------------------- From: "Jonathan Osuch" Subject: Re: Allegro Graphics Package Date: 18 Apr 2000 17:01:56 -0500 Tim wrote, > Although VESA support for the higher resolutions is problematic on some boards > these days ... That is the purpose of FreeBE/AF. I believe it is similar (identical?) to univbe. > Does Allegro have an X incarnation that can run in an Xterm?

This is, quite literally, rocket science :-). Cool! What are you going to do with this knowledge when you are done with the class?

I am working with GPS receiver models that contain Kalman filters, and we use Kalman filters to do orbit determination for the space shuttle and the space station. Kalman filters can be used in almost any situation where measurements are youse to calculate something. I haven't figured out any application to fractals ... yet :-) Tim Thanks for using Fractdev, The Fractint Developer's Discussion List Post Message: fractdev@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractdev" ------------------------------------------------------------------------------- From: "Scott D. Boyd" Subject: Xfractint 20.0.10 Date: 19 Apr 2000 16:20:30 -0500 I have been looking thru the source of Xfractint-20.0.10 trying to find the reason why it crashes with a segfault whenever I press Shift-2 from the main menu. I have discovered that the modified version of 20.0.9 that I worked on (which I called xfractint-dev) doesn't crash. I had submitted the changes to Tim Wegner, which he changed somewhat, and posted to the ftp server as xfractint-20.0.10. I still need to go through the 20.0.9 source and apply my original changes one-by-one, compile, and test. Anyway.... Here's something interesting I have discovered: When I run Xfractint in an xterm window, I can't use the Function keys. I need to use the Shift-n keys as indicated in the man page. *But*, when I run Xfractint in a Konsole window (KDE's version of xterm), the function keys work fine. Apparently there are some differences in the way Konsole and Xterm map the keyboard. Tim - you told me that the Function keys worked fine in your Xfractint. Are you running it from an xterm session, or something else?

I hope I didn't mess things up, by I guess I did. The intent of my changes was just to eliminate many of the #ifdef's. I didn't intend to actually change the executable code from what you had. I guess I should look through the changes. > Tim - you told me that the Function keys worked fine in your Xfractint. Are you > running it from an xterm session, or something else? KDE/Xterm session. I have a lot of trouble with Gnome/Enlightenment. I am using Linux-Mandrake 7.0.

This patch is so small for two reasons. I intend to start the process of interfacing with the Allegro package. Using Rich's work as a starting point, of course. I don't want any bug fixes lost in the muck. The second reason is that business will be taking me to Arkansas for the next week or two and I won't be online. I'll be around until Sunday evening.
