what are "memory leaks?"   I know you mean the ram right?  but in what way does it leak?  I'm tech savvy, just ignorant to some facts.

Quote
A memory leak is like a virtual oil leak in your computer. It slowly drains the available memory, reducing the amount of free memory the system can use. Most memory leaks are caused by a program that unintentionally uses up increasing amounts of memory while it is running. This is typically a gradual process that gets worse as the program remains open. If the leak is bad enough, it can cause the program to crash or even make the whole computer freeze.

An example from wiki:

Quote
[edit] An example of memory leakThe following example, written in pseudocode, is intended to show how a memory leak can come about, and its effects, without needing any programming knowledge. The program in this case is part of some very simple software designed to control an elevator. This part of the program is run whenever anyone inside the elevator presses the button for a floor.

When a button is pressed:
  Get some memory, which will be used to remember the floor number
  Put the floor number into the memory
  Are we already on the target floor?
    If so, we have nothing to do: finished
    Otherwise:
      Wait until the lift is idle
      Go to the required floor
      Release the memory we used to remember the floor number
The memory leak would occur if the floor number requested is the same floor that the lift is on; the condition for releasing the memory would be skipped. Each time this case occurs, more memory is leaked.

Cases like this wouldn't usually have any immediate effects. People do not often press the button for the floor they are already on, and in any case, the lift might have enough spare memory that this could happen hundreds or thousands of times. However, the lift will eventually run out of memory. This could take months or years, so it might not be discovered by thorough testing.

The consequences would be unpleasant; at the very least, the lift would stop responding to requests to move to another floor. If other parts of the program need memory — a part assigned to open and close the door, for example —, then someone may be trapped inside, since the software cannot open the door.

If this artical is anything to go by, the B-29 could still use more "beefing up".

I've been testing the B-29's ability to take battle damage also. It doesn't feel like the B-29 has been "beefed up" much.

As others have pointed out, that particular B-29 was probably very nearly out of fuel.

I don't know if AH models damage to fuel tanks v. the amount of fuel in those tanks.

I don't even need to set the fuel afire.

300 rds of 7.7mm (placed between inboard & outboard engine) and the wing of the B-29 will fall off.

Ok, did a few Beschussversuche   :D

Always shot at close range at the wing, right between two engines. I repeated each test several times.

With the light MGs of a D3A and I-16, it takes ~300 rounds to remove the wing of a B-29
With the 13mm MG 131, I had to use about 80 rds.
A 20mm MG 151/20 will destroy the wing with just over 20 rounds.
With the 30mm Mk 108 I needed ~6 rounds.
NS-37 (Yak T): 4 hits.

Then I tested the MG 151/20 and the Mk 108 vs B-17 and B-24 too (same target spot) and found the number of hits required to be about the same.

By the way, these numbers do match the Relative Projectile Strength table on the Trainer Corps quite well  :old:

what are "memory leaks?"   I know you mean the ram right?  but in what way does it leak?  I'm tech savvy, just ignorant to some facts.

*dusts off his "C+ for dummies"*  

First I assume you understand the two fundamental types of memory in computing?  One that keeps memory permanently (such as your hard drive with your family photos stored on it) and one that only exists as temporary and random-access memory that your computer needs to run and process running processes (and that gets "poofed" each time you turn off your machine).  This later memory is the RAM or temporary type that the computer constantly is accessing or releasing as it is needed to run it's various processes and tasks and is the cause of "leaks".  

The term "leak" is used because picture the RAM physicaly as a bucket of water.  As the processer requires memory from the bucket, it sips up what it needs and then when it's done it spits the memory it's no longer using back into the bucket.  The idea being in a perfectly programed world that no memory is ever just lost from this bucket, it gets used and when not being used it goes back into the bucket.  It gets sucked up, if it needs to be permanenetly stored then the memory gets transfered/copied to the permanenent memory world of the hard drive, then the temporary stuff gets dumped and spit back into the bucket.  You start to get a "leak" when this temporary data gets used/called up by a process, but then is unecessarily not returned/dumped back into the bucket when the need for it is done, thus it is basicaly out of the bucket and not getting back in (it leaked out).  Enter a memory leak fix, basicaly finding memory that was being sucked up outa the bucket by the processor and then not being spit back into the bucket when the need/use was done.

When a program or aplication, like Aces High, runs a single process (while many many porcesses are simultaneously occuring to generate an operating program) like say keeping count of how many bullets you have left in your machine guns, these processes require/consume a necessary amount of memory from the system's master cache of available/free memory (the bucket).  When the process if complete, say you land an no longer need to keep count of how many bullets are left in you guns, the memory that the process was earlier using and reserved for itself should be freed up or reset and returned back to the system's master chache of available/free memory.

It is bad if this doesn't happen, as in my example lets say you land one sortie and then up another plane.  Plane #1s ammo count is no longer necessary, but due to a looping effect of upping a new plane (starting a new process) without completely returning and freeing up memory from a previous and now redundant process (such as landing your old first plane and now upping a new plane, you and your system has no need for keeping the previous plane's ammo-count on-hand and in active memory.  Eventualy you're on plane #25 for the day, but your system still has inside of it memory being consumed by holding onto those ammo-counts that you had in plane #1, #2, #3, #4, etc. etc..), your system gradualy and steadily looses more and more memory that is not returned when the process is done using it.  So eventualy, if it's eaten/leaked away enough memory, you have nothing left in your bucket... now things start getting bad and noticable to the user, first with performance slowing down before it just starts to freeze/crash or random reboot due to a lack suffecient enough memory to keep running.

My thought is that the B-24 is catching fire even more easily. But the B-29 has four locations that can burn in the wing, the 24 only two. The structural strength of the wings seems to be the same (or B-29 beign slightly better). (See my tests above)

Lusche,

To quote the article which has been posted around the forum many times: "The Black Widow poured 564 rounds of .50 calibre machine-gun fire and 320 rounds of 20mm cannon shells into the staggering Superfort". The bird suffered no structural failure, but was in flames. Aces High's version looses a wing after 20 rounds of 20mm cannon shells. :headscratch:

Yes, but I think this is incident on the extreme side of things. If you would base the durability on that numbers alone, hardly any Superfortress would be shot down in combat in Aces High. It makes even wonder how the japanese fighters managed to shot down any B-29 at all.

You can find similar accounts for many other planes, which managed to survive a way greater number of hits then average for their type. The other end of the spectrum was the infamous lucky bullet.

I understand, I wish I had more material on the B-29 to comb over.

I pose you this question though, do you feel that the B-29 needs to be beefed up even more, going on both our results?
