I've never seen flex for sell.. how do I obtain a copy of it and whats the difference between it and flash?

Hey;
I've heard great stuff about flex but I've never seen it for sale. I've read that it is better for real time programs than flash. I don't know if thats true or not. What does flex offer that flash doesn't and how is the flex language better than the flash language? Or am I totally confused and is flex like an addon to flash??? any guidance would be really appreciated. I'm working on something Object oriented that needs to be in real time so I'm looking for the best program that offers that.

I'm pretty new at all thsi stuff too, and all these terms killed me for my first few weeks in this arena, but I've got my feet under me now.
Flex is an opensource SDK provided by Adobe (previously Macromedia). It used to be something they sold, but they opensourced it, Hoorah!!
Flash is the set of APIs that start with flash.*, and you can fully create flash animations with just the standard flash APIs.
Flex comes with a ton of very useful components, features, and functionalities that are built on top of flash. You should definitely download and get familiar with flex.
The flex api's start with mx.*
Flex also provides the ability to compile MXML documents into flash. MXML documents make it very easy to build Flash, full with animations, customizations, etc. in an HTML-like format. Take a look at the component explorer link below and you'll see the MXML generated for the example components. You can copy and paste that MXML (simple looking stuff eh?) and get a working app that you can expand on and play with as you learn.
Here are a few helpful links to get you moving in the right direction:

Oh ok, well that was what the test said prior to reformatting the hard drive. Now, it doesn't find any trouble no matter how many times I run it. That's what has me so confused, everything seems to check out and yet...I can't do anything, not even install the software!

How do i make a form that will tell me the difference between 2 figures?

how do i make a form that will tell me the difference between 2 figures? ie: the jan. value of account is 32,010 and feb value is 34,013 and march value is 31,089 i would like it to tell me the difference automatically... whichever it is bigger or less... i am sure that this is possible... but i am a complete newby to all of this and could use some help...
jan = 34,013
feb = 34,013
march = 31,089
etc...

Numbers will do the calculations, but it doesn't read minds.
The formulas shown in my previous post assume a table arranged like the example below:
The results in the bottom three rows (Apr, May and Jun) are correct for the simple formulas given and for the data entered in the Amount column as the empty cells are evaluated as containing zero. In practice, you would want a formula that suppressed the calculation until something was entered in that row of the Amount column. That's easy enough to add, should you think doing so will be useful.
But it won't make Numbers read your mind.

Whats the difference between these two queries ? - for tuning purpose

Whats the difference between these two queries ?
I have huge amount of data for each table. its takeing such a long time (>5-6hrs).
here whice one is fast / do we have any other option there apart from listed here....
QUERY 1:
SELECT --<< USING INDEX >>
      field1, field2, field3, sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end)
    FROM
      tab1 inner join tab2 on condition1 inner join tab3 on condition2 inner join tab4 on conditon3
    WHERE
     condition4..10 and
    GROUP BY
      field1, field2,field3
    HAVING
      sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end) <> 0;
QUERY 2:
   SELECT --<< USING INDEX >>
      field1, field2, field3, sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0))
    FROM
      tab1, tab2, tab3, tab4
    WHERE
     condition1 and
     condition2 and
     condition3 and
     condition4..10
    GROUP BY
      field1, field2,field3
    HAVING
      sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0)) <> 0;
[pre]

My feeling here is that simply changing join syntax and case vs decode issues is not going to give any significant improvement in performance, and as Tubby points out, there is not a lot to go on. I think you are going to have to investigate things along the line of parallel query and index vs full table scans as well any number of performance tuning methods before you will see any significant gains. I would start with the Performance Manual as a start and then follow that up with the hard yards of query plans and stats.
Alternatively, you could just set the gofast parameter to TRUE and everything will be all right.

What is the difference between Wine, Wineskin, Winery and Wine Bottler, and how do I get Wine to *ACTUALLY* work in Mountain Lion?

Ok, so this is my first post here and I am admittedly terrible at forums. Someone might say, "This was addressed in the ___________ thread by __________! Go read it!" --- that may be so but I've spent enough hours trying to google this problem into submission to no avail based on what is apparently working for others, so I would like a chance to get specific answers to specific questions that aren't from Mar 2011, etc.
So first of all, I'm confused by all the various Wine programs/apps/whatevers. I've seen Wine, Wineskin, Winery, Wine Bottler, and at this point I wouldn't be surprised if there are even more than that. What's the difference between all of these and how do they work with one another? What do I actually need to get windows programs working?
All of my google searches have led me to people giving out fish, but no one giving out fishing lessons. I'm not a pro at mac and windows and all that, but I'm a fairly bright individual who gets VERY frustrated, very quickly, when I don't understand the why and how of something I'm attempting.
I've also found "answers" where the person attempting to help starts off helpful enough, but degrades into the most archaic of techno-babble after about 5-6 sentences. On the other hand, I've watched tutorials on youtube where the poster decides to skip (apparently crucial) sections of the tutorial, and mutters such gems as: "... you might wanna have to run Wine first before you can do anything, cuz I think it has to configure it and set up a bunch of stuff"
O.o
A happy medium between techno-babble and the most basic of explanations would be ideal for me, and I'd imagine for others as well.
Here is a summarized history of my relationship with Wine:
Diablo II - I downloaded this awesome thing which ended up being... uh... I guess Diablo II in a Wineskin "wrapper". I'm not sure, all I know is that it's a D2 icon, and if I go to 'show package contents', it's got C drive, Program Files, et cetera inside of it. I double click it, it launches D2, and it works like a dream. <3
'Vanilla Install' - That's what I heard someone call it. It was the command/terminal style install using xquartz and xcode found at http://www.davidbaumgold.com/tutorials/wine-mac/. I followed every instruction to the letter, and got all the way to '$ sudo port install wine', at which point it started going smoothly, free from the possible error he described regarding the installation of xcode, and then just failed after I left the room to use the restroom and came back. Please don't ask me to repeat what the error was, because honestly, after reading more things on the interwebs, I'm confused as to why it's even necessary to go through all of that, so I'd rather not try that route again anyways, rendering the error message quite possibly irrelevant.
Wine + Wine Bottler - So I decided to try to seek out an easier method, as I know that one must exist that doesn't involve command lines. I found a video tutorial at http://www.youtube.com/watch?v=m0BBkISOcEA, and oh man would it be great if that method had actually worked. Again, I followed all instructions provided to procure my free fish, and at the point in the video where he declares that "xquarts or x11 will open" - it doesn't open. Nothing opens. I was trying to install Star Sonata, btw.
So here I am, thoroughly worn out, frustrated at all the random places Wine is installed on my mac now, and just want someone to explain it all, from top down, without getting toooooooo technical on me. I know that might be asking a lot...

## I know that the poster has already found a solution, but the following is a possible answer for others that have similar issues.
For Winebottler, just go to their website and download it. Run the program. Choose .wine as your prefix (best choice) or whatever suits you best. You'll need a functional X11. If you can't use the one that comes with your mac, download the latest one from the website.
If your issue is one with Winebottler's Wine not running correctly due to X11, then you have a pretty ugly problem, although a simple upgrade is the best solution (Upgrade XQuartz.app).
http://www.davidbaumgold.com/tutorials/wine-mac/#part-1
The above website is the easiest way to get REAL wine on your computer. First of all, Wineskin WInery, etc. are NOT WINE. They are 3rd party apps that may use Wine or may have originally part of Wine, but they are no longer up to date with Wine. WineBottler is currently up to date with the stable releases of Wine (but not the maintenence releases).
For the website tutorial and to run Wine on your mac without using a thrid party app, you will need to know a few things.
First, you will need to know basic control of the command line. That means, sudo (you must know the administrator password to your computer), and the forms of cd (change directory).
Second, you will need Xcode. Download 4.2 (stable) or whatever other versions you want, but beware: It is over 1 GB, and you will need time for it to work.
Third, you will need to get MacPorts and configure it. The tutorial should have this data.
When you download wine (use sudo port install wine-devel for the latest development release of wine), it will first download a lot of dependencies. This will take a while. After that, it will download wine itself.
After obtaining wine, to run a program, open the terminal.app window.
cd desktop/XYZ/ZYZ\ WRQ
The above will first enter the desktop, then folder XYZ, then folder ZYZ WRQ. From here,
wine th11e.exe
Or whatever executable you are trying to open. (Using Subterranean Animism as my example).
It should, in theory, run the program. Watch the terminal for errors. If there is an X11 problem, then it's not wine acting up. If the app crashes or has other issues, check the Wine Application Database to see if your app is compatible with wine.
If you have any further questions or other things, feel free to reply; I may or may not get back to you, but there's a good chance that someone will come in eventually. Otherwise, the Wine Wiki should have some information.

How do I obtain a copy of the discontinued iDVD software?

I need a to purchase iDVD but have learned that Apple has discontinurd the software. I know it works on 10.8 because I have seen it on a new MacBook Bro 17".
The question is: How do I obtain a copy of the discontinued iDVD software?

On an iLife 08 or newer DVD.
He's referring to the boxed disk for iLife 08, 09 or 11. All contain iDVD 7. You can the iLife 11 disc here: Amazon.com: iLife 11 (assuming you're in the States). Otherwise check the Amazon.com for your location.

Sorry to reopen an old post, but I've just purchased a 2nd hand late-2013 iMac (or so thats what the seller said).
I'm always sceptical though, and just wanted to know if there is a way to check if my iMac is indeed the late-2013 model that included Haswell?
I've attached screenshots of the About This Mac section hoping it may help shed some light.
Thank you in advance for your help!
PS - I can't compare to the iMac specs link you posted above because its now showing the late-2014 models.

How can I use LCCS with ActionScript 3 and Flash CS4?

Hi,
Using Stratus I was able to create an an application using Action Script 3 and Flash CS4. The sample code on the Adobe site was quite straight forward and easy to understand. I now want to switch over to LCCS but can't find anything any where on how to use Action Script 3 and Flash CS4 with LCCS. Do I need to know Flex to be able to use LCCS? Everything was quite simple and easy to understand with Stratus and makes complete sense. But LCCS is really confusing. Is there any sample code on how to establish a connection in Action Script 3 and then stream from a webcam to a client. There is nothing in the LCCS SDK that covers Flash and Action Script 3. Please help! I found the link below on some forum but it takes me nowhere.

Hi,
Welcome to the LCCS world.
Please refer to the SDK's sampleApps folder. There would be an app called FlashUserList. The app demonstrates how LCCS can be used with Flash CS4. Its a pretty basic app, but should help you moving.
We are trying to improve our efforts to help developers in understanding our samples. Please do let us know if we can add something that would help others.
Thanks

What's the difference between redundancy and recovery window for retention?

Hello all,
I'm still trying to get a grip on this concept for RMAN backup planning.
I recently ran into a situation as follows.
I have the backups set to a redundancy of 1.
I have instance1, which had GRID jobs to run RMAN backups as follows
Incremental database level=0 weekly at Wed at 2:30am
I have daily backups, incremental level=1 each evening
I have archive log backups through the day.
What happened, was that apparently on a Tues some time, the development team deleted data from almost every table in their schema.
The didn't discover this till midday or so on Wednesday.
I went to try to restore...and RMAN couldn't do it. I had found a SCN for early the Tues they did it...but I got the following error:
RMAN> RUN
2> {
3> SET UNTIL SCN 4590383198282;
4> RESTORE DATABASE;
5> RECOVER DATABASE;
6> }
executing command: SET until clause

ORA-01180: can not create datafile 1
ORA-01110: data file 1: '+DATADG/instance1/datafile/system.284.697137287'
From what research I did...it appears that since I did not have a level=0 incremental from before, it could not reset the database back in time. The previous one had been deleted since, I guess I had a redundancy of 1.
So, I thought I had a week backup they way I have it set..but that assumes that errors are found pretty quickly before the next level=0 backup.
I want at least 1 to 1.5 weeks worth of backups. I do have the problem that we do not have many tapes in rotation, so I cannot go for too long...may 2x weeks tops.
I'm trying to rethink my strategy, but I'm confused as I read as to the difference between setting RMAN retention with redundancy vs recovery window.
Can someone give me an explanation how you understand it? I'm reading on the web and in oracle books, and for some reason, it just isn't clear to me what is the best way to go....especially when I see that redundancy and recovery window might both be set??
Thank you in advance,
cayenne

Dear Cayenne
AFAIK RMAN doesn't claim that "you haven't enough backup". Please read the error you got carefully
ORA-01180: can not create datafile 1
ORA-01110: data file 1: '+DATADG/instance1/datafile/system.284.697137287'
and check the following link:
ORA-01180: Cannot create datafile 1 when doing RMAN restore onto 2nd server
Moreover, could you please use LIST BACKUP command and see whether you have enough backups?
Read "Redundancy Based Backup Retention Policy" from the following link:
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/strategy003.htm#sthref139

My student has been using Lightroom 4 with Photoshop CS5 on her Mac for well over a year. Because of the difference between the Camera raw version available to her in Photoshop CS5 and the raw process in Lightroom 4, she has been exporting her raw images

Any ideas?

My student has been using Lightroom 4 with Photoshop CS5 on her Mac for well over a year. Because of the difference between the Camera raw version available to her in Photoshop CS5 and the raw process in Lightroom 4, she has been exporting her raw images from Lightroom and choosing the "Render using Lightroom option when it popped up in the dialogue box. She has been doing this for over a year and a half without any problem. Today when she hit Command E no dialogue box appeared and the image just opened in Photoshop. I'm concerned that all of her Lightroom edits are not being rendered to Photoshop. Anyone have an idea as to how we can get the "Render using Lightroom" dialogue back?

How to calculate the difference between intdate and getdate

Hi,
My requirement is to get the data for all the claims where the difference between transactiondate and getdate() should be less than or equal to 7 which means any claims that happened in the past week.
So, my query would be something like this
select * from claims
where transactiondate-getdate < 8
But my transactiondate is in int format such as 20150331 and getdate would be in the format of 2015-03-31. Can someone please help me on how can i achieve the difference between these 2 date formats in the where clause.
Please let me know if you have any questions or if i am unclear.
Thanks

Hi SqlDev12,
Please find the below condition in your query,hope it would help you
DATEDIFF(DD,CAST(CAST(TransactionDate
AS
VARCHAR)
AS
DATETIME),GETDATE())
< 8

How do i leave a copy off sent emails on the server with mac mail

How do i leave a copy off sent emails on the server with mac mail.
Pop account

Check your mail preferences. The example below is from the mail app that comes with mac. In my case I'm using yahoo mail which is a POP3 account. POP stands for post office protocol which is the set of rules used by a POP mail account to transfer mail. You can learn more about it here if interested. If the box below is checked, all the mail will be downloaded to your computer when you check your mail using the built in mail app and removed from the mail server. Here is another page to help you set up your hotmail account for use the the mac mail application. Hope this clears things up.
