Which tool you use for your datamodel?
To show your tables with pk and fk and all.

other?

I am using ERwin® Data Modeler r7.1 (7.1.1.1207). It supports most new features of Oracle 10g such as hash, list, composite hash, setting LOB storage properties etc.
We just upgraded from version 4 recently. In the old version, I had to manually modify the generated scripts.
ERWin r7 supports all Oracle 10g (Release 2) new features we need for our projects. It offers far more functionality and options than the old version. It supports all partition types in Oracle 10g: Range, Hash, List, Composite-Hash and Composite-LIST and offers more storage settings.
Another nice new feature of ERWin r7 is that it offers purge option in the DROP TABLE statement. In Oracle 10g, the recycle bin contains all the dropped database objects until you permanently drop them with the PURGE option. Otherwise, you will see many funny looking objects like this: 'BIN$0+ktoVChEmXgNAAADiUEHQ==$0'.
With the purge option, you don't need to purge the recycle bin after the forward engineering.
SQL> purge recyclebin;
My favorite is Oracle Designer.

  • Which Bag do you use for your Camera? What about the GadgetBag 300EG?

    Which Bag do you use for your Camera? What about the GadgetBag 300EG?

    I agree - it's all about preference.  I use the ThinkTank Retrospective 7.  I *love* ThinkTank's attention to detail...  everything from having a rain cover included with the bag, to having ingenius use of velcro (sp?) patches to enable you to "silence" the bag so it doesn't make the big "SCRATCH" sound when opening the bag during a quiet event, etc.
    My best advice would be to do your research (which you're clearly doing) and have a clear understanding of the return policy wherever you buy it, and then don't be afraid to return it if you get it and feel it doesn't meet your needs.  A restocking fee is a small price to pay to not be stuck with a bag that doesn't work for you.  And if for any reason you get it and can't return it, there's always eBay.

    But of course I realize that is not the way of a modern programmer :-)No, modern programmers rely less on the brain part.
    I have heard other people saying that the (now free) [url http://www.oracle.com/technetwork/developer-tools/datamodeler/overview/index.html]SQL Developer Data Modeler is helpful for modelling. I haven't any personal experience, though.
    I have used it to reverse engineer the design resulting from the brain / pen / paper / scripts process and produce pretty pictures for the modern programmers to try and understand. It works quite well for this.

  • Which camera calibration profile do you use for your imports?

    I have a Canon camera, and have always just imported with the LR  settings left to Adobe default, including the Calibration panel set to  Adobe Standard profile. Sometimes it provides a satisfactory starting  point, other times not. Since reading in another topic's posts  concerning importing with other profiles (and setting them as a new  import default), I have tinkered around with trying this out. Just  curious how others handle their import settings. Do you leave everything  at Adobe default (basic, tone curve, detail, calibration)? Or, do you  reset to a  custom default? What are the actual settings that you use  and your reasons why. And, do you import with lens corrections enabled.  This information would be a big help in gaining a better understanding  of this aspect of LR.
    Thanks

    Rob Cole wrote concerning Lens Correction settings:
    I only do 80% of vignette correction, and 0% of distortion correction by default, and revisit that decision after importing, but nothing sacred about it - plenty of people use 100% for those too and do fine, or use their own pet numbers...
    Yes, absolutely use Lens Correction along with Camera Profiles. Like Rob said, "No reason not to!" But there are some considerations. You may like a little vignetting in the picture and 100% pretty much wipes-out all vignetting. Also, since vignetting correction raises image corner brightness, lens aberrations such as astigmatism and coma will be more visible and can reduce image quality near the edges. It's a trade-off as to what amount to use, which will vary dependent on your lens corner performance. I use a default vignetting setting of 50% for wide angle zooms and 100% for all other lenses, and only adjust higher if the image benefits from it. Distortion setting in an ideal world should benefit from 100% correction, BUT it can also degrade the corner resolution with wide-angle zoom lense images which typically have high barrel distortion. I use a default setting of 0%, and only use it for correcting images with obvious geometry distortion. Even then I rarely need to use 100% to make things look "normal." Chromatic Abberrations adjustment can safely be used at 100% for maximum benefit, assuming the profile is accurate over the zoom focal range. The new Adobe lens profiles seem to work very well in this respect.
    These are great"automatic" tool adjustments to make our less than perfect zoom lenses perform near prime lens image quality. OK, zooms don't have the wider aperature of prime lenses, but the high ISO of today's DSLR bodies give us a lot of latitude to play with!

  • Which CPU Cooler did you use for your CPU?

    Hi guys, just wondering, what CPU Cooler did you use in your mega 865?
    Did you use the Intel or the MSI CPU cooler?
    Which do you think is better?
    I used the MSI CPU Cooler, Which I think is better cause it has a copper base which can transfer heat faster. Also the heatsink must have been designed for the case too.

    ^
    The Mega 865 came with an additional "extra page" on how to install the Intel CPU Heat Sink into the 865, so it could be that msi thought that intel's solution was better? The manual of course had how to install the msi heat sink, so rather than printing the manual again, they provided an extra information sheet.

  • Which sleeve/bag/case do you use for your Macbook Pro?

    So what do you use? I've been stumbling across ebay to find something decent for my 15 inch mid 2009 but most of the sleeves don't fit the new macbooks...

    for my 17" MBP I use a Waterfield bag (http://sfbags.com). It's actually a sleeve and a cargo bag combo with a nice cable bag as well. Not cheap ($270 or so), but it's very well made and a very nice compliment to the apple in terms of fit, finish, and quality. The Waterfield bags are fantastic, and the sleevecases are very protective, such that you could buy just the sleevecase and drop your computer in whatever bag you like at the moment.
    For an older 13" white macbook, I have a Pinder thin, which is much cheaper (~$35 on sale) and is a nice thin minimalist bag. It makes for the smallest laptop and bag combo I've seen (prior to the air) that I would be comfortable carrying around.

  • Which 1GB memory do you use for your iSight iMacG5?

    Hello all,
    I just got my iSight iMac 20" couple days ago and want to upgrade with another 1GB memory, so I am wondering which 1GB memory module do you use or purchased from?
    I have looked up samsung and crucial, and I found newegg.com provides the best price so far.
    So please let me know what memory you have and where you got it. Thank you!
    By the way, will memory become cheaper during thanksgiving?

    But with 11g R2 now I want to know which way are you using to do performance tuning?
    Statspack? OSW? RDA? ADDM? Or other ways?
    Thank you.

  • How are the Apps Store and iTunes store different? Which do you use for what?

    Can you explain the difference between Apps Store and iTunes store? Is Apps a subset of iTunes store? To which store do you go for what?

    Apps you buy from the Mac App store can be used on your computer.  You use the same Apple ID as the iTunes Store, but that's the only connection.
    Apps you buy from the iTunes App Store are written to run on an iOS device (iPhone, iPad or iPod Touch).  They won't run on your computer, only on your iDevice.

  • Which tools to use for implementing an e-learning course?

    Hi,
    I was asked to develop an e-learning course. The course is ready and involves some power-points slides and perhaps some movies.
    What do you advise me to use? I have to develop a platform where you log on, follow the course and finally answer some questions in order to get a certificate.
    Consider that in Oracle I've always used only SQL Developer, APEX and a little of Forms. What of these of other oracle tools you would use for such an application?
    Thanks in advance!

    What this has to do with the current forum ?
    For the answer, Oracle's own Learning Library is using APEX to give a front end for organizing and searching such kind of recorded self learning tutorials. So it should be a good option to consider. Rest depends on what you know in a real good manner! Whatever it is, APEX, Forms, you can (and should) use that.

  • What RAID Setup do you use for your Macbook Pro Scratch Drive?

    Is there any benefit to using an Express-ESata Raid Enclosure vs a single esata drive as the scratch drive?
    If so, is there any benefit to using a 4 drive Raid 0 vs a 2 drive raid 0?
    What Raid setups are any of you all using with your MacBook Pro's? Is there a significant performance difference between using a E-Sata drive and a FW800 drive. Is RAID the right way to go?
    Sorry I'm not making a lot of sense right now, but I've searched through 20 or so pages of the forum and didn't see that anyone had addressed this question yet.

    OK, just to give you a frame of reference, I just performed the following tests -
    I hooked up my Sony AVCHD camera to my Mac Book Pro 2.4 ghz with 4 GB ram - (pretty close configuration to yours) - and imported a 26 second clip into FCP 7 with the following drive configurations:
    Capture to internal Mac Drive, no externals: 26 Second clip takes 44 seconds
    Capture to external WD USB2 drive: 26 Second clip takes 44 Seconds
    Capture to external CalDigit 2 Sata Drive Array, Raid 0, via Firewire 800: 26 Second clip takes 42 seconds
    OK, so now I move the camera over to my Mac Pro 8-Core, 2 x 3.2 Ghz Quad Core Xeon with 14 gigs of ram, and capture *to the same external CalDigit 2 Sata Drive Array,* Raid 0, via Firewire 800: 26 Second clip takes 11 seconds
    My conclusion would be the drives and drive throughput is not as consequential as the CPU horsepower in doing the conversion from AVCHD to Pro Res. However, there are many very knowledgeable people who look at these threads, and I would be interested to hear what they have to say.
    Hope this helps.
