What's the best fix for a slow computer?

What model computer? What are your primary uses and apps?
First thing anyone can do is replace or upgrade the system boot drive to SSD. Makes a very nice improvement.
How new or old is it? What version of OS X is it running?
Maybe it won't run faster but could run better with more RAM.
Take a look at all the tabs in Activity Monitor. If not on the Dock, go into Applications/Utilities and open it and keep it on the dock. Can tell you what is using your processor the most, RAM usage, disk and network I/O.
Don't install things that aren't needed. That can be counter intuitive to some but 'less is more' and some just really pull a computer system down. Security programs, "clean up programs" and others.

What's the best approach for handeling about 1300 connections in Oracle.

What's the best approach for handling about 1300 connections in Oracle 9i/10g through a Java application?
1.Using separate schema s for various type users(We can store only relevant data with a particular schema. Then No. of records per table can be reduced by replicating tables but we have to maintain all data with a another schema Then we need update two schema s for a given session.Because we maintain separate scheama for a one user and another schema for all data and then there may be Updating problems)
OR
2. Using single schema for all users.
Note: All users may access the same tables and there may be lot of records than previous case.
What is the Best case.
Please give Your valuable ideas

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<

What is the best practice for creating primary key on fact table?

what is the best practice for primary key on fact table?
1. Using composite key
2. Create a surrogate key
3. No primary key
In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
I also found a relevant thread states that primary key on fact table is necessary.
Primary Key on Fact Table.
But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
Having an artificial PK might simplify things a bit.
Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

What is the best app for backing up my mac. I do publication work and need to save my work?

what is the best app for backing up my mac. I do publication work and need to save my work?

My answer does not have the black Apple logo but the hardearned black belt of (bad) experience.
There is one problem with TimeMachine. It can get corrupted out of the blue with no warning and it will not want to restore correctly (as an added "bonus" you get to find this out the "hard" way, when you need it most). Plus it takes ages for the data to be copied back, sometimes days. Haven't tried my 600gb backup on Mavericks but Mountain Lion had this knack of breaking Timemachine after a couple of months.
To back up my entire server is use SuperDuper. It mirrors the drive to an external one (usb for example) The cool thing is you can use that usb drive and start the OS X from it (by holding Alt when you hear the boot chime).
This way you have a working copy of your entire machine. You can even go to another mac and boot it from there. I literally ran the OS X Server in my company from a usb drive on an old MacBook Pro until i got around to fix the problems with the actual server machine.
This has saved me twice already as the Hitachi drives Apple uses, tend to die like clockwork after 4000-5000 hours of use with no warning.
http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
PS. As a sidenote... SSDs are more reliable than a normal HDD (not to mention faster) I can't stress this enough, my Server is on two SSDs now. I can't tell you how stress free the setup is, it doesn't feel like a computer but more like a router, it just works... forever. After two years with SSDs my server has had two days of downtime and their health is at 97%, they will literally last 100 years with normal use. I'd go so far as to recommend you buy an SSD and move your old HDD to an external enclosure and use that as a usb backup. (for SSDs i use Plextor / Lite-On M3s (older) or the M6s (newer))

What is the best solution for me to run Microsoft Access on my brand new iMAC? Assume I'm a casual user.

What is the best solution for me to run Microsoft Access on my brand new iMAC? Assume I'm a casual user.
I am lead to believe by some real smart guys on the Apple site that If I have the Apple Store partition my iMAC and add the full suite of Office products on that partition, I can run the few Access programs I have and need to run.
Comments encouraged. Thank you in advance for your consideration and help.

You would have to install Windows, then install Microsoft Office Professional for Windows on it To install Windows you will have to choose between Boot Camp (faster, free) and a Virtual Machine (simpler, slower, easier to backup)
You should try LibreOffice (free), it can open Access files, it may not have all Access's feature set though, worth a try.

WhatÃÂ¢ÃÂÃÂs the best practice for this scenario?

Hi,
My users want the ability to change the WHERE and/or ORDER BY clause at runtime. They may define user preferences on each screen ( which is bind to a view object). They want to see the same records based on WHERE/ORDER BY defined on the last visit. That is why I keep the users preferences and load the screen based on that, using :
View.setWhereClause(...);
View.setOrderByClause(...);
View.executeQuery();
This works good when only one user working with the application but faced low performance when more than one user working with the application.
What are the points to increase the performance and what is the best practice for this scenario?
Thanks for your help in advance.

Sung,
I am talking only about 2 users in my testing. I am sure i missed something but could not recognize that.
This page is my custom query page including a tag to instantiate app module in stateful mode at the top <jbo:ApplicationModule..> and a tag to instantiate data source <jbo:Datasource...> and release tag at the bottom <jbo:ReleasePageResources..> and some java code in the middle(body). The java code constructed the query statement and then fires the query to set the view object based on the query statement using the above methods.
So, I am facing very slow performance(speed) when two clients load this page at the same time. Looks like the entire application locks for others when one client load this page and fire the query. i realized the battle neck is where executeQuery() is executing.
what do you think.
Thanks in advance for your comments.

What's the best app for taking a video on ipad2?

I am a tennis coach and am looking for an app for my iPad2 to do video analysis. I need to be able to video someone doing a serve and then show it to them in slow motion and be able to pause it. What's the best app for this?

Do some research into HTML5 video. Unless the user is using a modern browser with video playback capabilities, they would need to have an app to provide video playback, as well as the codecs for the video file format that you will be serving them. At this point in time, MP4 is the "clear(est)" winner of the online video formats. However not all browsers provide built-in playback. For instance, Firefox currently does not support MP4. Future Firefox builds will rely on whatever video playback the native OS provides. So coming back to your question - no, there's no real way of guaranteeing video playback on the web. You do the best you can and provide links to users where they can download the appropriate codecs and players and call it a day.

What is the best solution for running windows based programs

I have one program that I need windows for. What is the best solution for doing this without painfully slowing down my mac.

Depends on your needs.
BootCamp requires reboot and uses all physical resources of the system. Only OSX *or* Windows can run. Better for gaming or memory intensive tasks. BootCampAssistant must set up the boot sector to make it work. Also BCA required to remove it.
VM (virtual machine) like Parallels which "hosts" Windows while still running OSX. You split RAM between the two environments. VM is just another program so no special boot sector changes needed, but not good for graphics or RAM intensive programs.
Other recommended alternates to Parallels (paid) are VM Fusion (paid) and VirtualBox (free download from Oracle.com).

What are the best practies for naming symbols (spaces OK,etc.)?

What are the best practices for symbol naming for ease, flexibility, & to avoid "gatchas" down the road?
Does it make any difference if one includes spaces in the names of symbols? Are there any widely followed conventions for naming them like using camelCase or underscores?
Thanks!

Hi Gina D 3333,
Best-practice file-naming conventions for PDF files are the same as for any other file. I found this article on Apple's website that contains some useful pointers to consider when you're naming files that will be used on multiple platforms: OS X: Cross-platform filename best practices and conventions
I hope this helps!

What is the best practice for changing view states?

I have a component with two Pie Charts that display
percentages at two specific dates (think start and end values).
But, I have three views: Start Value only, End Value only, or show
Both. I am using a ToggleButtonBar to control the display. What is
the best practice for changing this kind of view state? Right now
(since this code was inherited), the view states are changed in an
ActionScript function which sets the visible and includeInLayout
properties on each Pie Chart based on the selectedIndex of the
ToggleButtonBar, but, this just doesn't seem like the best way to
do this - not very dynamic. I'd like to be able to change the state
based on the name of the selectedItem, in case the order of the
ToggleButtons changes, and since I am storing the name of the
selectedItem for future reference.
Would using States be better? If so, what would be the best
way to implement this?
Thanks.

I would stick with non-states, as I have always heard that
states are more for smaller components that need to change under
certain conditions, like a login screen that changes if the user
needs to register.
That said, if the UI of what you are dealing with is not
overly complex, and if it will not become overly complex, maybe
states is the way to go.
Looking at your code, I don't think you'll save much in terms
of lines of code.

What's the best photograph for a no background image?

I am about to photograph some products and would like to make a set up where I can photograph each of the products in the same setting/lighting. Then, when I go to open/edit them in PhotoshopCS4, I can take out the background and have just the image. Then, I can place that image ontop of any background I want. There is one bad thing. Some of these have a clear top where you can see thru them. Does or will that make a difference?
I want to set it up like they do for the weather on television, have a blue background and erase all of the blue showing. Then the only thing showing in the end is the digital background that was added in by computer and the weatherman(unless he's wearing a blue tie, in which case you can see the info through him). But my question still stands, what is the best setting for this and/or background color, how should the photographs be taken and then opened and edited(removing the background) using PhotoshopCS4?
We have a lighting set up, a 30" x 30" x 30" light tent setup, 3 lights with Pro Light Reflectors(one on the left, one on the right and one on top), 1 white and 1 black background and a box to place the images on. I'm using a Nikon D100.
Attached in a photo example.
This was taken with the black background and you can see the black through the bottle. I erased all of the surrounding black, but the dark shades still show on the sides.
Any help will be appreciated.
Sean

The whole point is that these photographs will be used for the book, manuals, magazines, ads... The backgrounds will not always be the same. That's my main problem. I am trying to figure out a way for the glass of the bottles to be "glass" images or "see through" so that when the photograph is placed on a background of, let's say, flowers, the flowers would show through. The edges of the glass are still solid and the flowers would not show thru them, but...
Is this type of thing possible for printing quality photographs?
Note - In the attched photo, it can be seen that the black background can be seen the plastic cap.

What is the best artical for understanding Data Pump

Hi,
What is the best artical for understanding the relationship / dependency of NETWORK_LINK with FLASHBACK_SCN or FLASHBACK_TIME .
Why it is manditory to have NETWORK_LINK , when we are using FLASHBACK_SCN or FLASHBACK_TIME.
Can some one explain the internal for that dependency
Thanks
Naveen

There's no direct dependency between NETWORK_LINK and FLASHBACK_SCN and FLASHBACK_TIME
As noted in this Oracle doc,
If the NETWORK_LINK parameter is specified, the SCN refers to the SCN of the source database
FLASHBACK_SCN and FLASHBACK_TIME are mutually exclusive.

What is the Best practice for ceramic industry?

Dear All;
i would like to ask two questions:
1- which manufacturing category (process or discrete) fit ceramic industry?
2- what is the Best practice for ceramic industry?
please note from the below link
[https://websmp103.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000409682008E ]
i recognized that ceramic industry is under category called building material which in turn under mill product and mining
but there is no best practices for building material or even mill product and only fabricated meta and mining best practices is available.
thanks in advance

Hi,
I understand that you refer to production of ceramic tiles. The solution for PP was process, with these setps: raw materials preparation (glazes and frits), dry pressing (I don't know extrusion process), glazing, firing (single fire), sorting and packing. In Spain, usually are All-in-one solutions (R/3 o ECC solutions). Perhaps the production of decors have fast firing and additional processes.
In my opinion, the curiosity is in batch determination in SD, that you must determine in sales order because builders want that the order will be homogeneus in tone and caliber, and he/she can split the order in diferents deliveries. You must think that batch is tone (diferents colours in firing and so on) and in caliber.
I hope this helps you
Regards,
Eduardo
