Sounds like a great program for the LD. I have gotten this yesterday and purchased via pay-pal is the new version since yesterday evening? Not sure what I am doing wrong? Thanks in advance.

I still figured you would want to know these things as they come up. If I am understanding how your app works and how the LifeDrive works, then I think there is a potentially bad side effect. Please correct me if I am wrong. The situation is this (and it just happened to me). Since your app locks the programs and databases in the cache by marking them as active(?)... if, for some reason, your device has a spontaneous reset due to a badly behaved program, you will lose everything done in the programs that are "locked in cache". I think this is due to the fact the the "locked in cache" database never get written to disk so the changes become lost. I had a program reset the LifeDrive and found that all my DB5 preferences were reset and the program marked as unregistered. Same for ZLauncher. Both apps started as if they had never been run before. Can you comment on this theory? Thanks! Mike

Sharkk717 What does Ludus mean? Join Date: Apr 2004 Location: USA Posts: 1,488	hi mike! no worries. this is most likely unexpected behavior as i haven't been able to reproduce this. the system will still put Locked databases in the cache onto the HD when you exit the app or turn off the LifeDrive. however, if there is an unexpected reset then yes your data will be lost. this happens even without SharkCache (it's part of the nature of the LifeDrive). my idea for a fix would be to have SharkCache periodically sync the databases back to the HD. does this sound acceptable? regards, sharky ps: sorry about your Databases getting reset pps: do you mind sending me an email (support at ludustech dot com or sharkboy717 at aol dot com)? __________________ Ludus Technologies LudusW, SharkMsg, SharkLinks, SharkBtn, SharkSwipe, SharkNav, SharkCache, SharkROM.

I think PalmOne should just paid you a bunch of $$ for this app. to be included in all future LD's. Maybe we should start an online petition... __________________ Loki: Treo 650 with 2 gig sd and Sony VAIO U71P

Thanks for the reply. No need to apologize for the data loss. Not a big deal. I am a developer as well. I know these things take time and Palm does not make it easy due to their strange kludges with each new device.

Are you sure the system puts the locked dbs to harddrive on exit of a program? That would explain some other behavior - but not this particular issue. If this is true, then maybe the issue I experienced was not a result of sharkchache then? I made the conclusion when considering the result and the nature of sharkcache and the lifedrive. Too many variables at play - and unknown palm implementation details.

I think your workaround is fine, if it is even necessary? ...but you may want to make it an option since there would be a performance hit occasionally when you sync the dbs back to the hd. Some people may not want the hit, others may want the "safety".

Thanks!

Mike

Yes... I will email you!

There are applications bigger than 2MB, but AFAIK, they're only games. Legacy (an RPG by RedShift) is around 4.9MB, while Rat Olympics (resembles a Java web based game like "Yeti Baseball") is 4.7MB. The latter is freeware which is nice for a game that colorful in hi-res, but no way in hell could I get it to run on my z71. Only on my T3.

about repartition - correct me if i am wrong but i think that OS5 is not able to address more than 64Mb of RAM.

Tapwave did it with the zod2. No1 seems to know how tho.

first of all, what you're saying about the heap is 100% wrong: the LifeDrive has 10 megabytes of cache (this is known as DBCache), and SharkCache only lets you use up to 4 megabytes of this space (40%). The other 60% is movable heap, for the system to use. it's possible to get an out of memory error, but so far i've only heard one report of that and that would happen without SharkCache (loading a huge site in Blazer > 10 mb).

You're wrong also about iSilo and TCPMP, since they read off the card (in this case the hard drive) and never actually put the source file into cache in its entirety (this is generally called "buffering"). ......................................

regards, sharky

I gotta ask Sharky. I'm going through all the posts preceding this one and I can't seem to find the culprit with the negative attidute towards your software. Was that post deleted?

By the way, I called the lag in the Life Drive the "Resident Evil Syndrome, load at every door
