  1. Re:Don't be so hard on yourself on Open Source Flight Sims · · Score: 1

    I can land a real cessna with just using trim and throttle with a bit on the yoke to make the turns in the pattern. I've never seen anyone come close to that with a sim even with all the fancy equipment. For IFR training, I wan the plane to work like a real one. Set the trim and point it in the general direction and make slight left, right adjustments and make sure the power is correct. In the real world, I can run 1/4 hour without adjusting the power or trim once its set right. I want a more realistic simulator

  2. Re:Is this H�kan Lans' system? on Guiding Air Traffic Sans Radar With GPS · · Score: 1

    So they keep the old system to sell more radars? I think someone's concept of ATC comes from reading one too many OOD books by Booch.

    Current ATC assums that the plane will suffer a radio failure at any time and works with that as a primary assumption. None of these other systems take that into account.

    A pirvate pilot is under no oblication at all in most places to talk to anyone. The exception is very high (class A) and major airports (known as class B). There are rules about entering class C without radios and most airports in the US don't have any radio requirement at all. The transponders are only requireed 30 nmi from the center of major airports and a few other places.

    The rules change when you carry passengers for hire or if your flying with instrment flight plans.

    When you file a flight plan you tell the FAA that your starting from where your are going and how long you expect to take. If its an instrument flight plan and your route doesn't conflict, you will be given approval or a modified version of the route. Once the plane is off the point of stopping on the runway, if a radio failure happens, you fly the proposed route. If your flying Visual rules (like most private pilots), your under no oblication to talk to anyone, anywhere if you avoid some classes of airpspace.

    The current ATC system allocates boxes. Each aircraft is allocated two boxes at a time and these tend to be along "airways" which are between VORs which happen to mostly be located at major airports. One is the box your in, the other is the box your going to be in next. If you have a working radio, it allows the ATC to drop your allocation of the box you were in once you cross a reporting station.

    Movies seem to give the impression that ATC control where the planes go which isn't quite true. They simply advise the pilots but its still up to the pilot to keep from running into thigns like other airplanes and mountains.

    So why is it that if you fill the memory with FF, you find more FF's in the TNEF data and when you fill the memory with 00 you find more 00 in the TNEF data? Is this leaking out uninitlized memory?

  12. Re:Sendmail IS more secure than Postfix?! on Bind 9.0.0 Final Released · · Score: 1

    I assume that there are security problems with all programs. A rapid fire kill to postfix shows its got one somewhere but its not worth my time to debug it so it looks like that flaw may not get published. You cant count on the "no publised flaws=no flaws".

    I know what happens when a hole gets found in sendmail. I do not know what happens with qmail or postfix since they never had this problem. I also compile from scratch using non-standard librarys which tends to make the system much more immune to buffer overflow cracks.

    If you look at the history of sendmail (or wash-u-ftp) cracks you will see that they have been cracked for much, much longer than these other programs have been around. If you look back to some of the common "sendmail" exploits, they where because of stupid stuff like the auto uudecoder that were commonly used more than a decade ago.

    Since DISA didn't publish what systems where cracked in which ways, I don't think you have the authroity to make your claim that no system was hacked because of postfix or qmail. All I know is they didn't hack my boxes and they were all running sendmail.

  13. Re:Security guarantee is limited on Bind 9.0.0 Final Released · · Score: 1

    Well, yes I would run sendmail.
    I used to run one of the only sites for DISA that never got hacked. Even the tiger teams failed to hack it and it was runing sendmail properly configured. Out of the several thousand sites they hacked in DISA, there were only about 6 that they couldn't crack and all of thouse were running sendmail.

    All programs have flaws and some times thouse flaws open it up to abuse. A secure server must keep on top of thouse flaws. At this point I think that sendmail is much more secure than postfix and qumail. I managed to get postfix to dump core a few times on the mandrake 7.1 that I'm runnng at home. Users should not be able to cause programs started as root to core dump.

    When we first got a 24 bit display at school, I wrote a program that would draw a rainbow which had wonderful changes between the colors except the orange bits. The thing just could not display enough shades of orange. I then wrote a color picker program that would display all 16 million colors over 16 pages of display. It turns out that about 8 million of thouse colors are brown when shown with other colors and even more look like ugly brown when shown by themselves. Extending the RGB model further just wastes more backing store memory for more shades of brown. From what I have seen, HSV would even work very well with 16 bit modes.
