Jet Engine Exhaust

I am interested in making jet engine exhaust for the planes in my 2D game. I have already read the other posts about particle systems and formulas, but i don't understand what I need to use as a "particle."
What exactly is one of these particles? Is it just an image of a certain darkness that can be changed for another lighter image as time progresses? Or is it something rendered in the program that doesn't involve any images? I don't seem to understand how i would go about drawing a particle system.
Any help would be greatly appreciated.

1) create a Smoke class
2) create a Smoke java.util.ArrayList
3) use smokeList.add( new Smoke(x,y) ); for every time the jet moves
4) make the Smoke class draw a circle with some small radius and the color (64,64,64)
5) as time progresses for any given Smoke object, set their radius larger, and the alpha lower.
I think I made a particle generator with a neat smoke effect...
Check out this place:

Theres only like 5-6 examples, find the particle/fireworks one...

Cannot open the Microsoft Jet engine workgroup information file

Hi,
I have 4 linked servers in a SQL Server database. One of them is another sql server database. This one works fine. I have 3 that are Access databases. Last week I could run a query against these linked servers, but now when I open SQL Server Management Studio I get something like the following:
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "HRDB" returned message "Cannot open the Microsoft Jet engine workgroup information file.".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "HRDB".
What does this error mean? I've looked at several posts, but none apply to my problem. I've looked to make sure there wasn't a .ldb open. Anything else I've missed?
Many thanks,
Mark

The key error is "Cannot open the Microsoft Jet engine workgroup information file". Here is a suggestion from a AccessMVP.
Are you using ULS (User Level Security) in Access, with a custom workgroup
information file (*.mdw)? If so, you may need to replace this file using a
copy that you should have backed up.
If you have not specifically implemented ULS, then you're still using it,
but you are joined to the file named System.mdw, with username Admin and a
blank password. In this case, which is more likely than the above case I
guessing, your copy of System.mdw may have somehow gotten corrupted. Try
searching your hard drive for this file. For example, my copy is in this
folder:
C:\Documents and Settings\Administrator\Application Data\Microsoft\Access
(Yes, I log on as Administrator on my PC routinely. Bad Tom).
Rename your copy of System.mdw to something else. Then try restarting
Access. Access 2003 will automatically create this file, if you are
permanently joined to System.mdw, and it does not find it during startup.
That should get you a fresh copy.
Good Luck,

POWERMAC sounds like a jet engine when trying to start up...!

Ive been using my G4 powermac as a 2nd computer and havent had any problems with it until today.
I turned the computer on and I get the white screen with the apple and then the computer gradually starts to get louder, and louder, and louder - almost sounds like a jet engine. I immediatly shut the computer down holding down the power button.
I tried it again and the same happened. Ive never heard the computer make this sound and it was getting louder and louder and was too afraid to let it continue.
I have important things on my 2nd computer that I need.
Should I let it continue? Has anyone experienced this before? I shut it down while the computer is still on the startup screen.
Help.

That is a safety feature to make sure it's not overheating when there's no OS to check temps or control the fans... at least on G5s, can't remember on my MDDs.
I have important things on my 2nd computer that I need.
If worse comes to worse you can pull the drive(s) to get at the info, or possibly use FireWire target disk mode...

Jet Engine 4 needed for Creative Media Source Corrupt Libr

I have seen this asked before but not answered well.
I just installed Creative Media source for Zen Touch. When I bring up Creative Media source it says that I have a corrupt media library and need to download current Jet Engine 4 from Microsoft. I do that but when I try to upgrade it get the message that I already have a newer version on my computer. I have tried uninstalling and reinstalling with same result.
Is this bad software (Creative Media Source) or screwed registry or whatever on my computer.
Better yet can I remove Creative Media Source and just use Microsoft Media 0, i.e. will the necessary drivers be available?
Creative Nomad Explorer seems to be working ok?

Dusty,
Have you also installed the Microsoft Data Access Components (MDAC) 2.8 available from Microsoft?
You can find the MDAC here - MDAC_TYP.EXE
If the difficulty persists, you can uninstall MediaSource via Add/Remove Programs Wizard in Control Panel, delete the MediaSource folder in n C:\Program Files\Creative and reinstall it.

Computer crashes, G5 fan goes jet engine

I've had this problem whenever compressing long movies that are an hour or over. Basically I set up the movie with the proper settings then leave it to compress overnight. What I've ended up finding in the morning is that the G5 fan is going full jet engine blast and the computer has hardcore crashed. I'm running on a dual 2Ghz G5 with 1.5 GB of RAM which is all Apple branded.
I'm running on Compressor version 1.2.1
Does anyone know the solution to this problem?

I had the same problem with my computer not too long ago, but it was still under warranty. Apple led me through a host of trouble shooting- the most emphesis being placed on my RAM. I removed the RAM, re-installed it, tried again- same issues. They eventually shipped me another Mac, but from the troubleshooting I was led through prior, everything pointed to the RAM being the culprit.

G5 Jet Engine FANS

My logic board failed and needed to be replaced after getting it back from the "apple approved" repair shop, upon "firing it up" the fans went into "take-off" mode, freaked me out as it didn't quit. I did a manual daily, weekly and monthly thru the "terminal app" from "Utilities" and no fix. I then went to the support/discussions here and followed all related links.
Okay, I have read all the posts for this problem and have, Installed iStat Nano which gives all the temps and fan speeds (3500 and up in this case) etc. checked to make sure the system was still the same (10.4.11), cleaned the "grills" all is dust free, I have reset the SMU switch, reset the Nvram and Pram, have place the Processor performance to "reduced" under energy saver in the sys prefs. And gentlemen, the fans are still running at 3500 and up with the exception of the "slots" and "backside" which are running at 250.
Any suggestions? The "Tech" who fixed my G5 had even less knowledge about this problem than I did before the problem existed.
I'm ready to go and buy the "ear mufflers" that the airport people wear around jet engines.
Any suggestions would be most appreciated!

Hey Mr. Paycheck,
Perhaps I misunderstood also, but our problems sure sounded alike. My fans ramp on sites with heavy graphics also but I've come to know that my fans ramp when ANYTHING causes my cpu temps to rise. Running on high power is unbearable as it immediately raises the temps and the fans come on to compensate. Perhaps if I hadn't had a Dual 2.0 before this machine that ran so quiet on any power setting I wouldn't be concerned. Annoyed, but not concerned.
I'm going to take my Mac in for service this coming week. If I can afford the repairs, provided they can find anything wrong, I will let you know how things turn out.
If I could figure out how to raise your ratings I would. Since I've been scouring the boards lately I've noticed your unfailing kindness in trying to help people out. A hearty thanks from all whom you've helped.

Jet engine on start

This week my G5 (PowerPC, Dual 1.8Ghz) began a new life as a jet. I shut down at the end of the work day, and have it auto-start a few minutes before my work day begins.
The past couple of days I arrive to a roaring system, the grey screen with the apple and its spinning icon. I sounds like either a fan or a disk drive out of control. I did a hard pwr down (the button) and then re-boot. The first day I went through this process 3 times until the machine finally booted up and acted normal. Yesterday no such luck.
I went to plan b and tried to start up in Safe Mode, (which didn't happen) taking 25 minutes to arrive at the normal desktop.
Once the machine is up, everything works fine. Disk repair permissions found no problems, Norton found no problems.
Last night I just left it running to avoid the start-up roar.
Any ideas on what is happening? I'm a new convert to Mac and if my Win PC makes these noises, it generally doesn't bode well.

You ran is reving up because your G5 is not detecting your OS. Therefore the OS is not there to regulate it and it goes into default mode, which protects your machine in case it is over heating.
Also, very few here would recommend using +Norton Utilities+ on a Panther install (even though Norton says it's OK). The last OS I used it on was 10.2 and only after all my other utilities failed; basically a last ditch effort. Norton is not OSX worthy and is no longer updated or supported in OSX.
Instead, try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. This is different then Permissions.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.

TestStand and MS Jet Engine Conflict

I have a MSVC++ 6.0 project interfacing with TestStand 2.0.1. I have an object that performs database operations on an Excel file using ODBC. What I have found is that I can perform database operations and then load a sequence without a problem, but if I try to perform another database operation after the sequence file load, I get a database error. If I move all the database operations to before loading a sequence then I don't have a problem if I use ReleaseSequenceFile(). Any ideas? Thanks.
-G-

Scott,
I'm using the Sequence Editor. What does OI stand for anyway? I did successfully login. The error is that the database engine believes it can't find a table, but if a sequence wasn't loaded before the call, it can find the table. Here's the flow currently:
1. Start the App
2. Create the TestStand Engine
3. Login to TestStand
4. Perform a database call
5. Use results for other stuff ( non-TestStand related )
6. Load a sequence
7. Sequence loaded
8. Repeat 4 ( fails )
It's the same exact call except I'm looking for a different value in one of the fields. The error is that the table can't be found. It doesn't make any sense how to the two are related. Thanks.

I have a 2011 Macbook Pro and it sounds like a jet engine or fans loud as crazy. What is the reason for this? Also I upgraded the Ram to 16GB from 4GB. I use a lot of video editing software and also run the Elgato capture device. Thank you.

Can somebody please help me with this problem. Thanks.

Try resetting the SMC
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

New 27'' Imac fan sounds like jet engine

Hi all, i am having some serious issues with my attempt to enjoy apple computers. I am a first time user coming from pc's, just due mainly to the price difference. I just got my first apple computer, a 27'' imac (the standard one, no bells and whistles for this struggling college student). Just want one mainly for recording music and doing research papers. Had to get the first one replaced due to a bad optical drive in the first day. Just brought the replacement home and after 2 days i turn it on and it sounds like a 747 is taking off in my bedroom. I am not the most computer savvy person around, but looked up as much as i could on forums. Tried all the resets and nothing works. Everytime the computer is on there is a turbine that also comes on. I downloaded the istat widget thing and it says my cpu fan is running at over 3000 rpms. I'm no air dispersment specialist, but to me that sounds high. Does anyone know if this is common as of late, and any possible fixes?? I have an telephone appointment with an apple guy tomorrow, but am pretty sure it is going to just turn into a "buy the 3 year $170 applecare plan" speech, like when i called for the disc drive.
Second, are apple computers poorly made?? I know it's wierd asking on the apple website, but i have to get some answers. 2000 dollars is alot of money to me, and the fact that i've had 2 problems in less than a week's time scares me. Should i keep trying to get a good imac that won't crap out, or should i buy something else? Thanks in advance for any replies, i really appreciate it.

Thank you guys for your comments and suggestions. I really appreciate it. I'm thinking of taking it in for repair or replacement. My only concern is that this is 2 times in one week i've had to go and get it replaced. And that's brand new. What is the reliablity for this product going to be in 6 months to a year. For 2000 dollars i don't expect to have to do that. Also apple is not paying my labor to repackage everything, take it down 5 flights of stairs, go to the inconvinently placed apple store at the center of an outdoor mall, pay for my gas, or for my time that i could be using to do something productive. I guess maybe i'm just frustrated, but still. Now if i get a new one i may not be able to enjoy it as much because i will just be waiting for it to break down. Maybe i'll just cut a flap in the new box so i can see the screen and a few holes in the back of the box to run the cables. Then when it breaks down i can just close the flap and push the cables back through, and have it all ready to go back in no time flat. Thank you again for your suggestions, i'm just very ticked off right now.

Problems with the Microsoft Jet 4.0 OLE DB

I'am trying to work with databases (Microsoft Acces) and
everytime a recive this message error(I've created a string indicator and link it to the General Error Handler ) :
"Conn getDataToModify.vi"Object 0x2222222 is not valid."
I don't understand who is "Object 0x2222222 ".
Another message says that an error was encountered in the Microsoft Jet Engine.
Strange or not the program worked fine until this error.
How can I debug this ?
Thank you.

What's obvious about this? I don't see the logic at all. What's different about a loop tunnel and a shift register that's wired to itself inside a loop?
I did make this change, and it took away the problem, but I'd very much like to understand what was wrong with using a loop tunnel. It seemed like the obvious (i.e. sufficient but as simple as possible) choice to me.

Usage of DATALOGIC JET with MAM25 and RFID

We are evaluating the Datalogic Jet as mobile device for MAM25. We want to us the RFID capabilities too.
It's not clear if the RFID interface provided by Sap on the MAM Cd , the SAP MRI, is usable with this device.
Anyone has some experience ?

If you are constantly adding data to an Access Database, the database is opened in process and the Access Jet engine will use a cache of memory based on the size of your physical memory.
Microsoft Jet allocates memory on an "as- needed" basis up to an internally calculated high water mark. The idea is to efficiently use the memory in large RAM systems without the need to adjust Registry Settings.
The high water mark (MaxBufferSize) for Jet is calculated by the following formula:
( (((Total Ram in MB - 12)/4 ) * 1024) + 512 ) KB
For example, for a system with 32 MB RAM, Jet uses a calculated MaxBufferSize of 5,632 KB. You can override this value by setting the MaxBufferSize value in the following HKEY_LOCAL_MACHINE subtree:
\SOFTWARE\Microso
ft\Jet\x.x\Engines\Jet
For Jet 4.0, the registry location for MaxBufferSize is:
\SOFTWARE\Microsoft\Jet\4.0\Engines\Jet 4.0
You may try to see what happens if you do not write any new recores to Access at all. See if you get an increase.
You may consider changing this value from zero to 0x200 (512KB) which should limit Access and allow you to see if any memory outside of Access is being lost.

Fans only run slow, not fast on PowerMac G5 Dual 2.3

I've noticed recently that some occasional kernal panics seem related to the fact that under a heavy load my processor fans are not revving up. This is on my olde PowerMac Dual 2.3 from some time ago. We have the same model at one of our workstations at work and the fans kick in and out as we render, so I know what a healthy PowerMac G5 Dual 2.3 should sound like.
I've checked inside the case... the two fans in front of the processors are running, just really slow. The same with the two rear fans. I can't get them to spin up faster when doing anything processor intensive. Seems like it's been like this for a while, though it was definitely not always like this as I recall a few mornings where I found it in jet engine mode.
The white tab on the clear plastic internal cover is seated correctly... I don't know where any other sensors might be.
I ran the Apple Hardware Test from my original gray install disc... upon booting into the test I was surprised to hear the fans revving up to full speed. On the first run the computer had no problems. After a reboot into the OS and then another reboot back into the test disc, the full speed fans just locked up the OS choice screen and I couldn't get past it.
I see plenty of posts here regarding loud, fast fans that won't spin down... but I don't find too many with this problem.
Can anyone shed any light on this?
Thanks,
Dave

I run BOINC on my Power G5 and it places a full load on the processors for as long as the application is up. I find the fans are not very loud if you have done a proper dust cleaning of the computer. This includes cleaning out the power supply that's located in the very bottom of the case. If you think you have a problem I suggest you look into Istat Pro from http://bjango.com/. This will allow you to look at the fan speed to determine if you have a problem or if things are running normal. Under full load, my fan data looks something like this.
Drive bay 1000 rpm
Backside 1100 rpm
CPU A intake Around 800 rpm
CPU B intake Same as CPU A
CPU A exhaust About 30 RPMs higer that CPU A intake
CPU B exhaust Same as CPU A exaust
Slots Intake 1560 RPM
The only fans that seem to change much based on load are the CPU fans and with no load they may drop to about 500 RPM. Under full load on a warm day and the system in need of having the dust clean out I have seen the fans go up to 950 RPM. The fans that made the most noise were the Power Supply fans when I missed blowing out the power supply for a while.
The G5 processor is able to run at temperatures up to the boiling point of water but it truth I have never seen mine get above 164 degrees fahrenheit.
If you have just done a good cleaning of the system, it's possible you have just returned the system to normal operation and extended it's life instead of having a problem.

MSI KT4V-L Random Reboots

Hello everyone.
I have a MSI KT4V-L that randomly reboots!
It can be doing anything from web surfing to F@H. Reboots.
I'm going to attempt a BIOS update in a bit, but here are the specs.
Older Antec Case w/400w SmartPower Single Fan (Rail's are multi-meter tested, +12v is around 12.35 - 12.43v. +5v is around 5.05 - 5.10v, +3.3v is around 3.37-3.41v)
MSI KT4V-L Motherboard (unknown bios version)
AMD Athlon XP 2000+ Palomino, Runs about 58ºC-60ºC load, which is fine for a Pally. Using a Coolermaster Aluminium/Copper HSF. Arctic Silver Ceramique applied.
1x512MB Centon PC2700 @ PC2100, 2.5-3-3-7-1T
Hercules 3D ProphetII GeForce 2 GTS 64MB DDR AGP 4x
Creative Labs Sound Blaster PCI
HP CDWriter 9300
20GB Western Digital 7200RPM
80MM Front Fan, 60MM Rear Fan
Everything seem's fine!
I do have another CPU to test it with (T-Bird 1.0GHz), I do have different RAM (2x256MB Nanya PC2700 Matched), I do have another PSU (Hipro 300w, 200w), HDD (Tons), Optical Drive (tons), etc etc.
So basically I can swap out anything besides the MOBO which has worked great for a long time.
Anyway,
I'm off to flash the BIOS.
I'll post back when I'm done. Wish me luck.

Hello Nick! Long time no see!
The processor temperature is too high. I think you should buy a better heat sink.
The CDRW should be Master at the end of a different cable from the system hard disk. The sound card should be in PCI slot 3, 4 or 5. Furthermore I think the exhaust fan should be better/bigger. That would also quiet down the system considerably.
HEY Fredrik!!!!
How ya been man?
Anyway..
The CD-RW, is, of course, Master . I put the 60MM exhuast fan on 5v cause it's obnoxiously loud. I moved the SB to the last PCI slot, at the bottom of the board, and added a nice PCI-Slot Exhaust Fan a slot above it, to get some warm air out. The ventilation in that case is quite nice now, and it's got tons of vent holes.
After a few hrs of folding, the temp is only 53ºC, so...that's a large difference.
It hasn't restarted in a few hours, either..but I'll probabally be picking up one of these when I have the extra cash. (After the holidays...or as my sisters XMAS preasent haha. )
Or, maybe a CM Aero 7 I think they are, w/those loud arse jet engine coolers.
Anyway, thnx man.

A disk in the DVD drive causes a crash, machine will not start

I have a fairly bizarre problem, searched, didn't find it in here so... maybe I am special. Anyway. I have a 2.4ghz MBP with 4GB of memory. I got it in November (with Leopard). It has worked without an issue until I started tonight to give bootcamp a go on it.
Symptoms:
- Leopard boots up fine, logged in, nothing else open
- Insert any disk (DVD, CD-R)
- Leopard crashes
- continues to cycle through a restart but it keeps crashing waits 1 min, restarts, repeat
- Even tried a Leopard disk
Tried:
- disk utility to look at things
- can't load anything to check the hardware cause its cd based
What I did before it started going nuts?
I used bootcamp to partition the drive. This worked fine. Stuck the XP disk in and it read it fine. Machine rebooted to install XP, this was fine. Things went well until the XP install asked for a reboot. Then it restarts, disk failure. I eject disk and select OS X. Off we go, things are good.
I delete partition thinking something got screwed up. Tried again. This time when I put the XP disk in the thing crashes while in Leopard.
While I have typed this my machine has restarted a dozen times on its own. It is kinda funny to watch but *** has happened to it? I can't even re-install Leopard... no drive.
The DVD drive does spin up but after a few seconds it crashes. Any ideas out there?

Maybe related...
Bought a 2.6G MBP yesterday, brought it home, booted up, everything great until I started loading my apps---CDs/DVDs would spin and spin, then eject---then Install Disc 1 froze the system. Can't eject the disc---onboard fans racing like jet engines and the keyboard area near the screen seemed very hot. Posted last night---someone thinks either bad optical drive or motherboard. About to go see a Genius now. For $3K+, this pretty much *****.
