Sorry to a pain. Ready to throw this out the window. It works good/great then very poor or not at all. In wireless mode.
The other day on the lap top a friend was connected to a inter-active training video. for about 30 minutes, worked great.
Then today the Dell with windows 7 lost the wireless conection.

A simple question about performance!

Hi! I have a simple question about performance. Suppouse that you have a servlet or a class with DB access, and you need to use a value several times in that page. What is best, to assign the value from say, a resultset or a request.getParameter() to a variable or to call the resultset or the request every time you need to retrieve that value? Which option uses less memory, which is faster, etc.?
Hoping the best fou u

If you need more values from a db, the best is to open some connections (connection pool) and use the for accessing the db.
To get the data only once, open the connection, get the data, store the data whereever you want: variable (class), hidden control (if you want to send from one page to another by request) and close the connection as quicky as possible.
The advantage of the first method is that the most time consuming activity (connections opening) is done only once.

Getting Started with CFBuilder - A Question About Project Settings

Hello All,
I'm just getting my feet wet with CFBuilder and giving it a spin after over a decade's worth of experience with Dreamweaver and I have a question about setting up my work environment.
First of all, I have two computers that I mainly work from. My home desktop computer, and a laptop for when I'm on the road. I keep all of my web site project files syncronized between the two computers using Dropbox.
I've noticed that when I create a new project in CFBuilder it stores a few files in my project root like ".project" and "settings.xml". It looks like "settings.xml" stores information about which CFBuilder web server should be used for the project. Unfortunately this messes things up for me a bit because on my desktop a web site project url might be: http://desktop/myProject/ and on my laptop the project url could be http://laptop/myProject.
The reason this isn't a problem in Dreamweaver is because dreamwevaer stores its configuration/preferences outside of my project folders so I can essentially define any testing server I want for both the desktop and laptop.
Is there a way to configure CFBuilder to store project settings outside of the project folder? Or does anyone have a suggestion for someone like me who syncronizes their project files from their laptop to their desktop?
Thanks in advance for helping out a CFBuilder noob.

I would recommend using a distributed version control system (DVCS) with a hosted service, such as using Git/Mercurial and Github/BitBucket/UnFuddle. With Git, you can use a .ignore file to specify files/folders that you want to exclude from being stored in version control (I also exclude my CFBuilder project files from my repositories). You would then sync your local Git repositories with your service of choice, and they would be accessible from any machine.
There are many advantages of using Git and a hosted service over just Dropbox:
Each computer has a complete copy of the code repository, including all code changes over the history of your project.
You store code modifications in "commits", or small entries in the DVCS.
Commits can contain user-defined descriptions that help you identify what you did at each step of your development process
You can roll back commits if you break something in your code.
You can create "branches" of your code when you want to work on a specific feature of your application, and that branch is kept in isolation from other branches until you are ready to merge it back into the main production code branch.
You can have public or private hosted repositories on the various services, enabling you to work with a team or participate in open-source development.
There are Eclipse plugins available for CFBuilder that provide GUI tools for working with Git and hosted repositories (unless you are comfortable with using the command-line to do all your Git interactions).
I don't think you can separate the project settings from the project in CFBuilder.

KDE4 + wallpaper slideshow: few questions about performance / tuning.

Hello,
I am using KDE 4.4 from pacman and set my desktop activity to slideshow. I would like to customize few things and thus - I have few questions:
1) Is it possible to change / disable transition effect when changing wallpapers? All my desktop is choppy and not responsive while the wallpaper changes and I am wondering if there is a way to repair this? (all images used as walls are at max 3MB big, usually something about 1MB. I have 7200 RPM disk, 2GB of ram and rather fast graphics card with newest Nvidia drivers, so I don't know what is the cause of slowdown...)
2) How can I programatically progress wallpaper to next image (not with the right click / Next Wallpaper image)?
3) Is there a way to disable the wallpaper change while there is a fullscreen application running? I am asking this, because when I watch HD movies and the wall changes, movie playback is really choppy... (I think that answer to the first question will also help me in this case).
I would be glad for any sugestions / interest in helping me;)
Best regards,
Mike.

Hello
1/ There's no way I know to remove the transition. Using the "raster" graphics engine helps a lot on performance : kill plasma-desktop and launch `plasma-desktop -graphicssystem raster`
2/ There's a plasma applet for this :

Maybe you can adapt it to your needs / find out how it works.

FCP X, a question about camera settings

I live in the middle of the Pacific and need some advice as there is no one here to help me answer these kinds of questions...
My first 3 big projects were done in SD using a SONY PD 170 and FCE4.
I just bought the Panasonic HPX 170 with a 64 GB P2 card. I use a new iMac i7 (OSX 10.7.2) with all the bells and whistles and have now gone to the new FCP X for software. I know the following is more of a camera question more than a software question, but I thought someone in this forum might be able to help me.
We are about to shoot another full length feature film (roughly 90 minutes). I have read through the manual and a book about the camera but I'm just not getting enough information to make the ultimate decision as to what camera settings I should use to shoot the film.
In the end I expect the film to show at a theater here on the islands for a few weeks, and then a few film festivals and then ultimately, hopefully, sell DVDs to people who do not have sophisticated plasma TV/DVD setups, so I have to consider this also when shooting the film.
So.... I would really, really, really appreciate some opinions as to how I should go about this, i.e., 24p? 30p? 720? 1080i? If it were you, what settings on the camera would you use to shoot this film???
Thanks so much in advance.

1080i/60 is your best choice.
(This is assuming there's not a great deal of fast action, or slow motion in the movie. If there is, you may want to consider 720p 60).
You really need to research frame rates and the difference between interlaced and progressive footage before you commit yourself. To be honest, the difference between 720 and 1080 is so tiny, I doubt many people could tell it apart if they didn't already know which was which.

Question about FCP settings

I must have changed something in my settings accidentally because for some reason whenever I drag a clip into the timeline, the the audio is not linked together and I always have to highlight the tracks and link the selection. What can I do to make the audio tracks be linked together by default?
By the way, im talking specifically about audio here--not about linking audio to video, but linking two audio tracks together.

LOB question about performance, fragmentation etc.

Well..
I want to discuss the issues around LOB objects.
If I have an enttity class with n-count fields and then a lob as the n+1th field, does this affect performance in any way ? E.g. if performance is random access for an object without a lob, does the performance get linear or something when the lob is introduced?
Another one:
If the latter is true: is it an option for me to use an @OneToOne mapping to compensate ?
What about fragmentation ? How can a database or whoever compensate for fragmentation, in the case the lob is the n+1th field ? Or just in general: How the fragmentation issues are handled?
(Im just thinking that lobs introduce fragmentation and brings performance down...)

This will be san=me if you are considering the Local interfaces.
For remote interface(like accessing EJB from Servlets resides in diffferent Apps Server) use the DTO(data Transfer Object) patterns.

Interview Question about performance

Could somebody answer this.
You get a call from database user complaining the database is very slow. Network issue is ruled out and you can't access any GUI tools like OEM, TOAD and Spot Light. What v$ views and columns would you see to if there is any issue with the db.
thanks in advance.

Questions like this one can go many directions. Since it is only one user complaining, I might start with v$session, v$process, and v$sql to get the sql text she is executing and test it for performance as a stand-alone query. I might also watch v$session_wait to see if I can see any sign of active waits for various sessions. Of course, if the user is doing a DML, then I might look at v$lock to see if any uncommitted transactions are blocking the user.
That is just a start. There are many places to look and many possible causes of slowdown.
Of course, the usual first questions is 'What has changed?'

Question about performance (entities & data object)

Hello:
I know that this can be, maybe, a silly question, but I've got the doubt
I get a local reference to a entity ( myEntityLocal ) and I'm going to get many values from it.
For example
myEntityLocal.getId();
myEntityLocal getName();
myEntityLocal.getAddr();
etc etc
My question is
Would be better, in performance terms, to fill all fields into a data object myEntityData ) and retrieve them from it ?
I mean
myEntityData = myEntityLocal.getData() // where getData() calls getter methods on myEntityLocal
myEntityData.getId();
myEntityData.getName();
myEntityData.getAddr();
I think the result is the same because is a local reference, but I've got that doubt
Thanks and regards

Questions about Performing a clean install of Snow Leopard

Hi I plan on performing a clean install of Snow Leopard. I've never done a clean install of any OS before. I have a couple of questions. Is it easy to do? is it safe? Is a clean install of Snow Leopard better than doing an upgrade?
Do I have to format my new internal hard Drive that I recently installed or only my Main drive?? It's basically used to store movies and music. Any info is greatly appreciated

why and what exactly do you mean by clean install? install on an empty drive?
I've never done a clean install of any OS before. I have a couple of questions. Is it easy to do?
yes.
is it safe?
yes
Is a clean install of Snow Leopard better than doing an upgrade?
IMO, not if your system is working ok. doing an erase and install will buy you a lot of work migrating your data.
Do I have to format my new internal hard Drive that I recently installed or only my Main drive??
yes. boot from the snow leopard dvd, reformat your drive with disk utility (it's in the Utilities menu). set the partition scheme to GUID and format to MAC OS extended journaled. once the drive is reformatted, quit disk utility and proceed with the install.
It's basically used to store movies and music.
I don't understand, is it empty or does it have something on it already? all that stuff will be wiped out if you follow the above procedure.
Any info is greatly appreciated
I would recommend doing a regular install. just make sure you have a *full backup* before you do. a bootable backup using CCCloner or Superduper is teh best. a TM backup is ok too.
BTW, you have posted this in the Time machine forum for leopard. this is really not the right place to ask this.

Question about video settings

Hey, I have music videos and tv specials on my ipod and was putting them under the correct settings recently instead of them all being listed as movies. The tv specials were fine under movies, but the music videos are another story. While they do show up on the music video listing, they also show in my music listing- its really annoying because I expect the video and all I get is a preview shot of what is in the video and i do hear the music playing. My question is this due to me changing the equalizer settings in the info on these music videos to music videos and putting the artist name on or what?

Kristina, it might be worth checking to see if you're running afoul of this problem:
Videos labeled TV Shows in iTunes don't appear on iPod
(but i'm not sure that's it, given the symptoms you're describing.)
there are some other possibilities that might be worth checking on here:

Hi shahchin,
I think you should check this Toshiba document:
[How to change the settings for the integrated webcam if the image is very dark or black |http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=59]
Furthermore the microphone is located on near the microphone because its a part of the webcam.
Regarding the picture quality of webcam you could also try reinstalling the webcam driver from Toshiba website.

A question about project settings..FCP 7

I am using FCP 7 and I'm a little overwhelmed with the myriad of project settings options.
I use a Canon T3i and film in full HD (1920x1080 i think). All my footage I transcode in compressor to Apple ProRes 422 before importing to FCP projects.
I installed another computer and reinstalled FCP 7 and lost my old templates and importing some footage, I get the red line indicating unrendered footage.
Is there a standard setting that Compressor and FCP use to make it easy to just transcode, import, and edit? I'd like all my projects to look the best possible in full HD and there's hundreds of preset project settings and I'm a little unfamiliar with all the options.
Anyone have any quick tips, pointers, or thoughts?

If you drop a clip into the timeline, it means the sequence settings don't match the clip settings. Make a new sequence, add the clip. FCP should ask "do you want the sequence to match the clip settings?" Click YES. If you don't see that, you might need to trash your preferences...or it might be an older version that doesn't support ProRes formats (FCP 5.1 and earlier).
Another way is to choose an EASY SETUP that matches your clip settings, and then make a new sequence.
And your camera shoots 1920x1080p...not i.

Question about Performance

Hi
we have a Sql Server Azure dabase with a Standar 1 subscription.
I make a test, inserting 400.000 records in a table, with 15 columns and one key (identity)
I have made queries and the performance is very bad, for example:
- a group by one of the table fields spend 16 seconds returning 585 rows
In other situations, the queries spend more than 2 minutes.
is this normal for SQL AZURE?

Hello Javier,
Can you please share which edition of SQL Database you are using? You should check if you are maxing out the available resources of the edition you are. If so and you don't achieve your performance goals, you should consider using a higher performance level.
The below article has some guidance:

If you're having performance issues then start a new topic regarding that.
There is a low FPS in the game "Tomb Raider" (less than 22). Could this be due to damage to the board or the old bios (version 1.7)?

Not if everything else works fine...
Sounds like drivers possibly need an update.
