Ideal accounts for fast rebuild

Hello Fico Family Right now myfico scores report that my scores are between 567-569 all CA's. I currently have collections and charge offs that i am working on to either pay and or PFD. 3 months ago I took on a 1000 CL CAP 1 secured card and try to maintain my balance at $100. I have 2 car/installment loans 1 with a late payment in May 2015, and 1 with 2 late payments on 2/15 and 11/14. I plan to make payments on time, but should I take on any store or credit cards for a faster point increase? Also what credit cards should I get?

I would get those lates removed first from those car/installment loans by writing GW letters, they are prob tanking your scores.

How do I manage multiple iCloud accounts for personal iCloud Drive & personal calling?

Yosemite has the ability now to make and receive phone calls as well as to use an iCloud Drive to share documents across devices (similar to DropBox, but as you will see with one major customization flaw). These are wonderful featurew, however, unless I am following the directions incorrectly my computer with Yosemite has to have the same iCloud account as is used on my iPhone for iMessage (for calling) and for virtually everything else for iCloud Drive (ie there is no way to set-up a separate iCloud account for iCloud Drive).
Now for iMessage I use a private iCloud account, but for the iPhone itself I actually use an iCloud account shared with my family. Why? Because when we use a shared iCloud account we can share a number of things here such as:
Location on Find iPhone. This works way better than find my friends and also makes it easy for us to lock a device if it's stolen since all of us know how to do this.
Calendar not critical, but allows us to put some family events here
Notes, Very cool as we can share shopping lists which is very helpful when you show up at the grocery and want to know what to get or to Costco etc
Reminders Also very cool as we can create reminders for each other for when we get home or whatever
Files on iCloud Drive Yes there are some files that it would be nice to share and we can do this (ideally there would be multiple accounts for this)
Now I haven't really used iCloud Drive much but you can easily imagine how some documents I might want to share with the family on iCloud while other's I might not.
Now when you switch your Facetime iCloud account to the same as the iPhone that is one private iCloud account shared with an application on another device that uses the same iCloud account. That is NO PROBLEM. However, the minute you activate the ability to call phones it requires that you now have the SAME iCloud account in the main computer. Now BINGO I have a problem as noted above I want to be able to share certain things with other devices.
Does anyone have a solution or workaround?
Otherwise it seems the only thing to suggest is that Apple consider a feature enhancement that allows you to make cell calls from your computer WITHOUT switching the iCloud account to the main account. For that matter it would be very useful if they could figure out how to partition the iCloud features so that I can decide which iCloud account does what or like DropBox give permissions for certain things and allow the individual users to decide what they want and don't want.
Thanks.

Gail,
No you are not being dense, you are just trying to be helpful. I may not have explained the problem very well. Setting up a Family iCloud account works great! However, if that account name is also used for your iMessage, Facetime, and now cellular calls you have an issue with your calls going to the entire family (or worse the thing just not working), your iMessages if multiple phone numbers are trying to use the same icloud account usually get messed up, and their Facetime accounts might end up showing up as you instead of them. In fact, I think you can't call your family members in this situation and I'm not sure iMessage works very well either. So what everyone does is create a personal iCloud account for personal features such as iMessage, FaceTime, etc.
Now in theory I could co-opt the Family iCloud account for my calls, but then no one else would be able to use the call feature, because unless I'm mistaken you can't have multiple phone numbers attached to the call Forward and still have them recognize which calls to forward to which phones. If they don't care for this feature it might work (I'm experimenting now), but I don't think that's what Apple intended.
It is possible to do a switch, which may be what you are suggesting. This would involve creating a separate profile on the computer that is used for making phone calls. I would, however, still need to co-opt the iCloud account for just my number and worse I wouldn't be able to make any calls unless I was in that profile. One of the great advantages of calling from your computer is that you make the call while you are working on something else which is inevitably your work or your personal stuff which is NOT likely to be in the newly created family profile.
Thanks for the suggestion, but I hope this helps you understand either how little I understand of your suggestion or why it doesn't quite meet my needs.

One account for mulitple individuals/devices

I have a group of individuals that we work with for our business - we are hoping to use one iTunes account for all of them to access information on their provided ipads. Will this work? This would ideally allow them to purchase apps for this business purpose and would sync to all the accounts if we are using the cloud?

How do I transfer information from my family's account to my own personal account for my MacBook, iPhone, and iPad?

My family has always shared an account but I recently got an iPad and MacBook Air for college and we have reached our 5 device limit before I could access my laptop. It seems as if my only option would be to deactivate a device-not ideal, or to create my own account for my 3 devices. The problem here though is we always used to share music this way to avoid purchasing the same song 3-4 times. Is there a way to sync a new account I create to the old one to retreive all of my old music to put it onto my iPad and iPhone and laptop, and is there a way I could potentially still access HomeSharing or allow access to each other's clouds?

There is no 5 device limit.
There is a 5 computer limit.

Grouping Credit Entry in Bank Account for Vendor Payments using Pay Wizard

Dear All
We are currently testing Payment Wizard for BACS Payments to Vendors . We have successfully posted payments to Vendor Accounts and to the Bank Account in GL. However we note each Vendor payment is credited to the Bank Account individually even though the Bank will take the payment in one amount for the Payment File Total.
Is it possible to credit the Bank Account with the Total Payment Run value as one amount only so that the credit matches exactly the manner in which the Bank will take the payment ?
I realise that we could process BACs through a dummy GL Account for the Bank and journalise to the Bank Account in total but would prefer to avoid this option.
Regards
Seán Lyons

Dear Seán,
Welcome you post on the forum.
Even though it is not ideal, you may not be able to avoid such additional clearing account since the way B1 works can not be changed.
Thanks,

Trouble with database connector for FAST for Sharepoint

I have plenty of experience with the JDBC connector for FAST ESP using Oracle, but this is the first experience I have with the same connector for FAST for Sharepoint (F4SP). I've created the XML config exactly to specs based on the technet guides
and configured my user accounts on the SQL Server appropriately. I'm using SQL Server 2008 R2.
If I try to use a Windows account, no level of access granted on the SQL Server results in a successful login. Any attempt to use the connector is met with "Login failed for user: domain\username". If I try a SQL Server account, I no longer
see a login failure, but this instead:
PS C:\FASTSearch\bin> jdbcconnector start -f ..\etc\DTtest.xml

set up according to the technet guide, including the encrypted password set by the encryption utility run the in F4SP Powershell. The same user who runs the connector also ran the encryption tool, so that should not be a problem either.
I've never had this kind of trouble connecting to Oracle databases with the JDBC connector for FAST ESP. Any suggestions? These failures aren't exactly helpful to me. Thanks in advance.

I found the solution to this problem in case anyone else was still curious.
This was caused not by JDBC settings, permissions/access on SQL Server, etc. It was caused simply by a missing SQL Server in F4SP configuration. When you run the F4SP config wizard, either as single-node or multi-node installations, the wizard
might end up ignoring the value you select for SQL Server, even if you are using a deployment XML file. When configuring as a multi-node setup, the wizard ignored both my deployment XML tag <connector-databaseconnectionstring> and the SQL Server
setting done manually in the wizard itself. Examing the evidence, I suspect this was caused by corrupt installation media (since the installer also failed to create some core files in /etc upon doing a reinstall).
The bottom line is that you must see a value for SQL Server in your install_info.txt file in order for the JDBC connector to work with SQL Server, like this:
Other services
Log Server:             myserver.mydomain.com:13415
SQL Server database:    jdbc:sqlserver://myserver.mydomain.com;DatabaseName=FASTSearchAdminDatabase;integratedSecurity=true
If you see this instead, the connector will never work:
So, the JDBC connector is certainly dependent on the main configuration of F4SP, regardless of what SQL Server is targeted in your connector's XML configuration.
Other services
Log Server:             myserver.mydomain.com:13415
SQL Server database:
;integratedSecurity=true
I had no idea there was a connection between my install_info setup and the use of the JDBC connector. But, the connection makes sense considering this was the error message from the JDBC connector:
09:20:04,016 ERROR [JDBCConnector] Caused by: No suitable driver found for ;integratedSecurity=true

Ideal size for library?

Is there an "ideal" size for the library? I notice that after 1gb iPhoto slows a bit.
What are some suggestions for the optimal size before moving it to an external HD? Mahalo. JB

You should really not be having any problems with that much RAM, unless your expectations for performance are really high - is the slowdown disproportionate?
About what icon size are you using for the Organize view, how big is your screen, etc.? iPhoto 4 was dog slow, and iPhoto 5 got slower, but iPhoto 6 has been nothing short of zippy.
You should try rebuilding your thumbnails if you haven't recently. Cmd-Option while launching iPhoto brings you four checkbox options. If you have the time, pick the first three, rebuild, and see if that helps (it's the iPhoto equivalent of take two aspirins and call me in the morning)

Trying to account for dozens of unidentified TB on SSD

I am working with a late 2009 27" 2.66Ghz iMac running OS X 10.9.3
It is fitted with 16GB RAM. the Operating system and applications are on a 240Gb OWC 3G SSD.
Issue: When I go to SSD > users > user name and use the 'get info" tool it tells me that there is 58TB in that folder. I go into the user name folder and run a "Get Info" on each folder I see there. However the sum of those folders adds up to only 11TB.
Any ideas as to what might be going on? How I can find what is in the other 47TB? I hate the idea that my SSD is filled up with stuff I cant account for.

If you have a 58 TB folder on a 240 GB volume, that's a problem. If, on the other hand, you actually meant 58 GB, then see below.
For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

What is the suggested frame rate to record in for fast / slow motion processing from a clip recorded

I want to create a video however I only have 1 dslr camera and I want the ability to post process the clips I record to be either in slow motion or fast motion. I don't want to have to record something in 24fps then 60fps. is there an ideal frame rate for both. What are some of the best practices for this in regards to recording and post processing in Premiere Pro.
Example of fast and slow video. Thanks.
http://vimeo.com/75259949

The ideal is to shoot in different frame rates, one for real time footage and one for fast or slow motion clips. This is called under and overcranking. It means you have to decide when shooting whether the clip will be real time or not.
Less than ideal is to shoot everything at one frame rate and then slow it down or speed it up later. It's less than ideal because the effect is never as perfect as the ideal method. Especially in PP, which does not do very well with slow motion to the point I recommend using After Effects instead. (At least with 24 fps media.)
On a side note, you can help solve the horrible slow-motion problem:

Recommendation for fast Mac for databases or way to make Mac faster?

I've currently got a Mac mini 1.83 GHz Intel Core 2 Duo with 1 GB RAM running OS 10.6.8. I'm on a quest to either make my current Mac faster or find the ideal mac for databases. I upgraded recently from 10.5.8 to 10.6.8 in the hopes of making my computer more stable and faster, but things are running slower. No wonder, Activity Monitor hardly shows any green memory. Apple doesn't seem to sell memory for this Mac anymore. So I'm wondering whether it's time to just get a new Mac.
What Mac would you recommend for someone not using videos, music, images on a regular basis? Would you consider any of them to be overkill for mostly running database programs? Or would any particular one be insufficient?
Thanks!

Well, almost correct. This computer is used primarily for work, which typically involves FMP or Excel, a browser, less frequently page layout software, Acrobat, emulators of older Mac OSs, and very rarely videos, graphics or audio files. The original problem that led to this post was with a large Excel file that started going haywire. Troubleshooting that led me to repair permissions, repair disk (nothing wrong), reset all sorts of prefs, and eventually install 10.6. After that install, Excel became extremely slow, and other apps also took much longer to open. So I cleaned up Font Book, got rid of unnecessary widgets, emptied caches, and otherwise tried to streamline things. The only startup item I have is for the printer. The other day I realized that Firefox is guzzling any memory that looks free to it, even if I don't have 50 tabs open. Followed steps recommended by Mozilla to solve that, but it seems to guzzle even more now (over 450 MB with 2 tabs open). I don't have Cocktail or Onyx, but maybe that would be the place to look next. I'll try resetting PRAM & SMP next.
I do want to start backing up the files I'm currently working on on an hourly/weekly basis, if not the whole HD. I've been lazy about that. Since that will involve buying an external HD, I've been putting it off to see whether it's worth it to stick with this computer (and get an HD with Firewire 400) or wait & get an HD with Thunderbolt. I dropped in at the Apple store yesterday to look at the new Macs, and they seem to be running fine without any memory guzzlers (even on those with just 2 GB), though the app startup time was a bit slow.
OWC looks great; I'd just have to either find a Swiss equivalent or wait till my next trip back to the U.S., which isn't around the corner.

How to account for and set the temperature in testing

The problem is this: I'm setting up an airflow resistance test and I need to account for temperature and barometric pressure. However, I don't know how to setup LabVIEW to account for these variables.

Devont:
Actually this issue is a fairly complex problem in aerodynamics. I am
an aerospace engineer who has developed computer code for this very
purpose in a couple of wind tunnels. When you say you are setting up
an airflow "resistance" test, what physical (aerodynamic) properties
are you trying to measure? Tunnel flow velocity? Mass flow?
Aerodynamic properties on a test model? (lift and drag coefficients,
center of pressure, gross forces?)
If you are trying to measure air flow velocity through a wind tunnel
test section, then the next question is what type of sensor system are
you using to do this? A pitot-static probe? A hot wire anenometer?,
an LDV (doppler laser)? Each has different techniques for getting
back flow properties.
Also what kind of tunnel is this? Low speed subsonic (say less <100
M/s) Mid speed subsonic <0.6 Mach? Transonic 0.8 to 1.2 Mach?
Supersonic 1.2 to 4.0 Mach? Hypersonic (say >4.0 Mach?) This will
make a great deal of difference in computing flow properties.
Mach number is a ratio of the flow velocity to the local speed of
sound where;
M=v/a where a is the speed of sound.
a=(gamma*r*t)^0.5
where gamma is the ratio of specific heats Cp/Cv, r is the gas
constant, and t is the absolute temperature. Gamma is a constant up to
about mach 4 but really starts to fall apart after that so this speed
of sound equation becomes a lot less useful for hypersonic analysis.
At low speeds gamma for air is approximately 1.4, r is about 287 for
air. At STP, the speed of sound is about 340 meters/second.
What is the scale of your tunnel? What is the density altitude of
your tunnel? What is the fluid medium in your tunnel? (Is it regular
air or something else?) These play into computing flow properties
because they affect a dimensionless flow property called the Reynolds
number which affects how the flow in the tunnel behaves.
You will need to consider also humidity which affects the density of
the fluid medium in your tunnel. Water vapor has a molecular weight
of 18. Dry air (0% RH) has a molecular weight of about 28.9. The
more water vapor you have, the lighter the sample volume of "air" will
be. The ability of air to retain water vapor is a function of
temperature, so a relative humidity of 100% at 0 degrees C will
contain much less water vapor than a relative humidity of 20% at 30
degrees C.
Because of something called the "boundary layer" the velocity profile
will be faster in the center of your tunnel than at the walls. It
will resemble something like a U shape for higher Reynolds numbers and
for very low Reynolds numbers may look more like a parabola. Reynolds
number is computed by:
Re=rho*V*L/mu
where rho is the air density, V is the flow velocity, and mu is a
property called the kinematic viscosity which is a function of
temperature.
The Reynolds number, like the Mach number, the Nusselt number, and a
few other fluid dynamics properties is a dimensionless ratio. Flows
with a similar dimensionless property should behave more or less the
same. This is called similitude.
Mass flow calculations first require that you know the air speed
profile of your tunnel and then you will need to compute the density
of the air in the tunnel and then perform an integration process to
calculate the actual mass flow through a particular plane of interest
in the tunnel.
Also, even when you put a test probe into the tunnel to measure the
flow in the tunnel, this will interfere with the free flow to a
certain of the tunnel. To minimize this, the test probes have to be
carefully designed and their size needs to be much smaller than the
overall tunnel dimensions. Later when you put a test model in the
tunnel, it and it's mounting system will also have an interference
effect on the tunnel that has to be accounted for.
To give a simple (perhaps an overly simple) answer to your question,
temperature and barometric pressure will play into your problems of
computing forces in that they affect the density of the fluid medium
in your tunnel via the unified gas law (which is a combined expression
of Charles and Boyles laws for perfect gases):
PV=nRT
or
Pv=rT
where rho, the density is the inverse of v, so this is sometimes
written as:
P/rho=rT
This only applies for perfect gases though. A perfect gas is one
where the constant pressure and constant volume specific heats (Cv,
and Cp) are fixed. The hotter and more dense the fluid medium, the
less true these equations become.
Temperature in these equations doesn't mean the common ways that we
ordinarily talk about temperature when cooking or talking about the
weather. Instead of C or F, temperature in the gas law must be on an
absolute scale such as Kelvin or Rankin. 0 degrees Kelvin or
Rankine=-273.15 degrees C or -459.67 degrees F. One Kelvin degree=1.8
Rankine degrees but both start at the same point of absolute zero.
For standard atmospheric conditions (called STP for standard
temperature and pressure), 1 cubic meter of air weighs about 1.226 kg.
You have to calculate the density of air at non standard conditions
by solving algebraically for the above gas law equation.
r is called the gas constant and can be derived from the universal gas
constant R (8314 units I can't remember of the top of my head but it
involves kJ/kg.mole or something like) by deviding by the molecular
weight of the gas in question. If the gas is a mixture then you will
have to apply the partial pressures rule to come up with an averaged
molecular weight of the mixture. Dry air contains mostly nitrogen
which has an atomic weight of 28 (about 79%), and then oxygen (about
20%) which has an atomic weight of 32, and the balance (about 1%)of
inert gases (Helium, argon, krypton, etc.) which have much smaller
atomic weights. For dry air r (small r that is) is about 287.
If the air is not dry, then you have to account for the water vapor in
the air by figuring out what partial pressure of water vapor is in the
air and then performing an average between the water vapor portion and
the other components of the air. Wator vapor only has a molecular
weight of 18 (1 Oxygen + 2 Hydrogens=18) and so is lighter than dry
air and tends to make the air less dense.
The partial pressure of water vapor that can be supported in the air
is a function of temperature that more or less grows exponentially
with temperature. I'm sure if you search the web you can find several
empirical equations for this. Relative Humidity (RH) is an expression
of how much water vapor is in an air sample versus the maximum that
can be supported at the current temperature of the air sample but what
you really want is the partial pressure of water vapor in the air.
There are sensors that can give this to you by measuring the
electrical conductivity of the air. Dry air is actually a very good
insulator, whereas water vapor decreases the insulating property of
the air.
All other things remaining equal, increasing the humidity will
decrease the density of the air.
All other things remaining equal, increasing the temperature will
result in decreasing density while decreasing temperature will result
in increasing density. If the temperature in your tunnel is different
than standard then you will need to account for this.
Tunnels generally heat up the air by the way when they accelerate the
air through the fan and also through boundary layer friction with the
tunnel walls. Many tunnels actually have heat exchangers to keep the
air from getting too hot. You will need to make sure you measure the
temperature at the same point thats you are measuring the static and
stagnation pressures in your your tunnel so that you can account for
its effects. Standard temperature is 15 degrees C or 59 degrees F.
For conversion purposes, 15 degrees Celsius =288.15 degrees Kelvin= 59
degrees Fahrenheit=518.6 degrees Rankine.
All other things remaining equal, increasing pressure will result in
increasing density, while decreasing pressure will result in
decreasing density. Barometric pressure is usually given by the
weather service as inches or millimeters of mercury or sometimes
millibars. For conversion purposes, 29.92
inHg=760mmHg=1000millibars=14.7 psi= 101325 Pascals pressure. If the
pressure in your tunnel is different than standard then you will need
to account for this.
Depending on tunnel velocity, you will also have to consider
stagnation versus static properties. Stagnation properties are what
you measure if you bring the flow at a point to a complete stop, i.e.
the kinetic (as opposed to random thermal) energy in the sample is
completely converted thermal energy. How you do this depends on what
speed of sample you are trying to measure and is the subject of whole
books. Suffice it to say that at low speeds there is little
difference between stagnation and static properties but the faster you
go, the less resemblance they bear to one another.
Compressibility is another issue. At low speeds air is
incompressible, but at higher speeds v>100m/sec, compressibility
becomes worth accounting for in your measurments.
At higher temperatures and velocities, (high supersonic, or
hypersonic, or high temperature >500 degrees C), the constant pressure
and constant volume (Cp and Cv) specific heat assumptions break down
and so does the gas law. The simplifications that can be made for
using the ratio of Cp/Cv (called gamma) also break down because Cp and
Cv and therefore gamma all stop being constants. Solving flow
problems in this regime becomes much more complex requiring numerical
models for Cp and Cv and requiring numerical (as opposed to simple
analytical) methods to compute flow properties.
Once you know the flow density, you can calculate air speed. For
lower speed low temperature tunnels (low subsonic) you can use a
simple incompressible Bernoulli equation for converting pitot-static
pressure to air speed. At higher speeds and temperatures this depends
on the regime (transonic, supersonic, hypersonic, etc.)
The Bernoulli equation is simply:
Pstagnation=Pstatic+1/2 rho * velocity^2
For lower speed supersonic, the isentropic gas relations are sometimes

In any event, you have to be sure to get your units right. If you use
metric, pressure is Pascals (Newtons/m^2), rho is kg/m^3 and velocity
is meters/sec. It's harder in U.S/U.K units because of conversions
between slugs and pounds etc.
Also you have to consider the concept that there will be a steady
state average that you will measure and a transient/turbulent portion
that will occur for each parameter that you measure (temperature,
pressure, RH, etc.) that you will need to account for.
Once you know the air speed and the density, you can compute their
product - mass flow. Mass flow then can be used for other purposes
such as calculating performance properties if you are testing a jet
engine or propeller or something.
Hot wire anenometers work by heating a wire and measuring the
resistance of the wire. The faster the air flow past the wire
filament, the more it will cool. I don't remember the equations off
of the top of my head but I believe that there is a square rule
involved. Hot wires work better at lower speeds than pitot-static
sensors but both become less effective the slower you go.
LDV's are neat, high tech toys that I haven't had a chance to work
with yet but they measure the airspeed by measuring the doppler shift
in the light emitted by a laser beam going through the flow, much like
doppler (WX-88) weather radar works. They actually measure the speed
of the air more directly than the pitot-static or hot wire methods are
probably simpler to implement from an equations point of view but they
are very very expensive.
In conclusion, I know I have written a lot of stuff up here that
probably sounds pretty intimidating with regards to solving your
problem. It would help to eliminate some of this by telling us more
about your test problem so that we can make the appropriate
simplifying assumptions. Tell us more about the details.

Motherboard does not POST - Decompressing BIOS image to RAM for fast booting

I recently returned my motherboard for a warranty repair due to a noisy northbridge fan. Following the repair my system was rebuilt however the motherboard now fails to POST indicating "Decompressing BIOS image to RAM for fast booting" on the LED D-bracket. Prior to the repair the system was running ok.
I have tried resetting the BIOS with the jumper and also reconnecting all of the cables and only the minimum required components to the motherboard (CPU, memory, graphics card). The motherboard was also reinstalled inside the case to ensure no earth between the case and motherboard exists.
Does anyone know why this error is reported, what is the cause? Could it be that the motherboard is faulty or have I perhaps damaged the CPU or memory modules during the rebuild?

I have tried all of the valid combinations with the memory modules with no other components but the CPU connected to the motherboard but still no POST. I'm currently waiting on a response from MSI regarding this issue but I'm beginning to think the motherboard is damaged. I've already endured a 12 week wait on the motherboard being repair via Dabs it is looking like it will have to go back again so its going to be 4 months without my system

Which is better having many Window User Accounts for the same person, so to have many Firefoxes or have many Firefoxes under one Windows Account User?

Right now I have around 6 Window User Accounts (just for me on one computer) because I did not know that I could put more then one Firefox per account. I have to leave the tabs up when I close Firefox because if I just bookmark them I wont finish my work I was doing with those sites. Now that I know how to put multiple Firefoxes under one user account. Which would make my computer fast or does it not matter, if I put all my Firefoxes on one Window user account or have 6 Window user accounts, each with their own Firefox?
-Thanks

It is more work to switch to another Windows account then to open another Firefox instance with another profile.
If you only use the other windows accounts for using Firefox that way and not for other purposes then there is nothing against switching to only one Windows account to make it easier to manage things as backing up your personal data or copying your data between the other profiles.
So it is up to you if you want to switch to only one Windows account.

DOES WORKFLOW 2.6 REQUIRE ORACLE ACCOUNTS FOR USERS?

We would like to integrate Oracle Workflow with our existing implementation of Oracle Portal. I was hoping that, by using OID accounts and groups, that SSO could be used to access whatever workflow functionality was required by our users WITHOUT also creating an Oracle account for each of these users.
IS THIS FEASIBLE?

There might be some configuration required, but this should work. Workflow only requires the Oracle HTTP Server + ModPLSQL to render screens.
The Oracle Plug In for Microsoft IIS is available for Windows NT and Windows 2000.
To quote the Configuration Guide:
Oracle Plug-in for Microsoft IIS enables you to use Microsoft Internet Information Server (IIS), the Web server included with Windows NT, to directly access PL/SQL and Java Web components stored in the Oracle database server. This plug-in provides a fast and integrated method of accessing PL/SQL and Java Web components running in the IIS environment. Oracle Plug-in for Microsoft IIS provides functionality similar to Apache's PL/SQL Gateway (mod_plsql) and Apache's mod_ose in the IIS environment.

Hi,
My client is evaluating Oracle Workflow and would like to know if we could use IIS for the web side of the Workflow applications.
if not can Oralce 9ias be installed on the same server where IIS is currently installed.
Any help is much appreciated.
Many thanks
Nazeer Ahmad Syed.
