Which is a better source for an Indicator, physical or logical

Hi guys,
this is something I was wondering -
which is better for filtering out a value? (for example to Count measures with certain Indicator equal to Yes).
A) Logical (check "Use existing logical columns as the source") and the use something like CASE Logical table.Indicator Measure When 'YES' Then 1 END
or
B) Physical (create a column and in Data Type select the Column mapping and map as
CASE Physical table.Indicator Measure When 'YES' Then 1 END
Physical table is the same.
I know, it's always best to push things to DB back. But in this case, it'd be the same, it doesn't appear to me which option is better at this point.
By the way, both of them work.
Thanks

Both should be same. You can verify this by checking the physical sql generated by using both methods. Most likely they would be same.

On iPhoto you can click info and see which camera was the source for the photograph, is there any way to identify which camera took the video on iMovie?

Is there a way to determine which camera was the source for video clips in iMovie? You can do this in iPhoto by clicking info but I can't find out how to do it in iMovie.

Not as far as I know. (you can often tell from the file name format).

Which is the better converter for mts and mpg files?

Ok, I just have a quick question regarding conversion software. Does anyone know which is better...PAVTUBE or CLIPWRAP2? Besides the cost...pavtube is cheaper. Which one is faster and offers the best quality? OR is there even a better one out there? I have mts files and mpg files I'd like to convert for use in FCP 6.

Which is the better lens for wildlife, sport action canon 70-200 is usm ii series L or Canon 100-400

Which would be a better for wildlife and sport action Canon 70-200 mm is usm ii serie L f/2.8 or Canon 100-400 mm f/4.5-5.6?

On what camera? It makes a big difference depending upon whether you are using full frame or a crop camera.
Also depends upon the particular sports and type of wildlife most commonly involved, how much reach you might need. Outdoor, daytime sports vs indoor and nightime sports is another key factor.
On a crop camera a 70-200 is generally a lot more usable than it is on full frame, for sports and wildlife. An f2.8 lens and 70-200 might be ideal for indoor sports even with a crop camera. It also might be plenty for large game that can be pretty closely approacted. But for small and more shy wildlife, sports on a larger playing field, you'll more likely need the 100-400. But as an f4.5-5.6 lens that's going to be more of a daytime-only lens.
The 100-400mm is unusual in that it's a push/pull zoom. This can be particularly fast to use and makes the lens popular among photograhers shooting fast moving subjects such as birds in flight and air shows.
If you give serious consideration to the 70-200/2.8 IS II in combination with teleconverter EF 2X III, I'd suggest renting and trying them toghether first. The reason is that a stronger 2X teleconverter has more effect on image quality than a weaker TC. The specific combination of the 70-200 Mark II lens and the 2X Mark III TC is pretty darned good.... better than the combo earlier versions of each item. But whether or not it's up to your expectastions is a judgment call only you can make. So it might be wise to rent before you buy, just to be sure.
If instead you start to take a hard look at the 100-400mm, once again you might want to rent it and give it a try. Some people really like the push/pull zoom design. Some don't. (I'm one of the latter... but to be fair this is largely an old prejudice from trying to use that type of zoom in the past, long before IS. I always found push-pull zooms hard to get a steady shot with.... But the 100-400's IS goes a long way toward solving that problem.)
And those two really aren't your only choices.
Personally I use a pair of crop cameras (7D), most of the time one fitted with a 70-200, and the other fitted with a 300/4 IS, sometimes in combination with an EF 1.4X II teleconverter. Or, when I don't need to be mobile and can set up a tripod, I'll use a 300/2.8 IS, both by itself and with EF 1.4X II or 2X II teleconverters.
Another possibility is two lower cost lenses... such as a 70-200/4 IS in combination with a third party lens such as the Sigma 120-400 OS or 150-500 OS. Those lenses are considerably less expensive than the 70-200/2.8 II and the 100-400, respectively. You might be able to afford both and still find they meet your needs very well.
I use the 70-200/4 IS, as well as a copy of the first version of the 70-200/2.8 IS, and they are excellent lenses too. No doubt about it, the 70-200/2.8 IS Mark II is top of the heap and exceptionally good... but rest assured those other 70-200s are no slouches.
If using a full frame camera, for large field sports and more distant, smaller wildlife.... better start saving up. You're going to need one or two of the super telephotos, such as the new EF 200-400/4L IS 1.4X that I'm saving up for!
p.s. By the way, if not already doing so you might want to try Back Button Focusing. It's a very popular technique among sports/action and wildlife photographers. I've been using it for years for virtually everything I shoot, and can't imagine using any other method now.

Suggestions on which iMac is better suited for me ...

I am stuck between two iMacs and was hoping I could get some input from you experts.
iMac A: 24" 2.93GHz C2D, 4GB, GT130 512MB
iMac B: 21.5" 3.33GHz C2S, 4GB, HD 4670 256MB
My main concern is Aperture 3's performance. I have about 40k images that are mostly JPG, though I'm now shooting RAW only (Nikon D50). My current iMac isn't all that speedy in Aperture to be honest.
Will the 21.5" be much of an upgrade for me? Its a faster CPU, but also less video memory. I haven't been able to find much about the GT130 versus the HD4670. Which one will be better for Aperture?

Tom, you have quite an investment in that current iMac A configuration. My guess is iMac B will be a better performer but I’m wondering why you wouldn’t consider a 27” iMac with i5 processor (or even i7) given you are not overly pleased with your current machine’s performance? Perhaps you are concerned that the 27” is just too big a screen, but if you have a place for it on your desk, you may be happier with it, especially in terms of performance on some tasks. Aperture doesn’t always use all the processors you have for every action, but it does for some of the major tasks that you may like to see speeded up. The i5 can match the speed of the 3.33 GHz C2D due to the Turbo Boost feature when it is only using one or two processors under light load; under heavy load, the GHz drops but you have two more processors to throw at the tasks. The i7 can exceed the speed of the C2D and i5 and adds Hyper-threading for even more throughput under load.
If your demands tend to be reasonably light, the iMac 3.33GHz C2D may be good, but given your investment, I’d recommend at least the i5 or i7 with more video memory.

Which is a better choice for me? A Macbook Air 11" or 13"?

Hello! I am soon to be a college student and I am debating whether to invest in an 11" or 13" Macbook Air. I've decided that I wanted a Macbook Air because I want a lightweight portable laptop with long battery life. But which size? Through some YouTube reviews I've heard a lot of things, I heard that the 11" is better than the 13" just because everything is smaller and more portable, the screen saturation makes it looks better than the 13" and just the freedom to carry it around and hold it under one hand is the ideal college laptop. But I also heard that it's horrible for holding memory and RAM (which I am completely ignorant about.. and quite frankly not too anxious to get educated to), so the Macbook Air 11" is an excellent SECONDARY laptop. Which freaks me out because I was actually leaning towards the 11" rather than the 13"
I don't play any games, nor do I video edit much. I just want a laptop that can hold all of my pictures, hold documents for school purposes, and play Spotify while I do my work. I don't really care about the Retina Display, only because I didn't spoil my self with it. But that being said, whatever Air I'm going to buy, it will become my one and ONLY laptop and it will serve as a PRIMARY one. Given I don't do the complicating video editing (unless it's a college assignment), or gaming with it, which laptop do you think is right for me?
Thanks for reading everything!
Should I still be safe and just get the 13"?
Please put your input!

Forget everything you think you know. The MacBook Air, 11" or 13", is a very powerful computer that can be the sole computer for anyone who doesn't require extremely powerful graphics. (This is because these computers use Intel integrated video rather than discrete video cards which Apple puts only in its top 'Pro' computers.) For most college students the Air is a perfect computer and if you configure an 11" and a 13" MBA with the same amount of memory, same size SSD, and same processor the only difference between them is the size - which, by the way, will also give the 13" a slightly better battery life because its battery is larger.
The 11" has a 128GB drive and cannot be upgraded which for some people makes it a tight fit for some but roomy for others. I'd have difficulty making it my only computer but my wife probably could. This is one of three advantages the 13" model offers (to me). The second is the longer battery life. The third is that I found the 11" model to be too cramped. The keyboard is the same size as the 13" but somehow I felt terribly cramped and the screen was too small. That's why I walked in thinking I'd get an 11" and walked out with the 13" MBA. I'd strongly recommend 8GB whichever model you choose.

Which is a better buy for college a non-retina display 15 inch macbook pro with a 2.6ghz processor or a 2.9 ghz 13 inch non retina max specs macbook pro both with 8 gb of ram will be using to write papers basically for general use im a Science major

im a college student im studying to be a vet tech and i want this computer too last which a more sound investment the non retina macook pro 15 inch with these specs:2.6 ghz 1 tb ata hd with 8 gb of ram or a maxspec 13 inch mac book pro: 2.9 ghz 1Tb and 8gb of ram any help is appreciated thank you

Hi,
I am a researcher so I store a lot of papers, data, and use numerical software. I have had a 17inch high spec macbook pro for over a year now. I find that apart from the large screen, it was unnecessary to get the high specs. This is why. Firstly, the hard drive is easy to replace and upgrade, apple charge a lot for their own ones. Secondly, the ram in my one was upgradable (which i didnt know when i bought it) and i since upgraded to 16gigs from 8 and its amazing. Thirdly, the newer macbook pros run hotter than the previous ones.
The retina is overrated and the programs for retina need more memory and processing power, so what you find is that your hard drive will get taken over sooner, your mac will run hotter, and battery life lower.
I would say to you, dont worry about the processor speed, the normal speed offered is perfect, more than that is not necessary unless you are running highly demanding apps, the mac will run hotter too. Dont bother getting a large hard drive in the macbook. Get a flash SSD drive, and buy a good portable 2tb HD, like a WD one, and use that to store as much of your work as possible. I believe apple started soldering their ram cards to the motherboard or something so that people cant upgrade. Check in advance and see if the macbook you want can be ram upgradable, then get a lower ram model and buy good 8gb ram cards to make 16gig. Very very easy to install them, took me about two minutes to do mine, it will be much cheaper.
If I think of anything else i will post back. Dont forget to install GFX card status too and use integrated only when on battery, i get up to ten hours of battery life without wifi, around 8 with wifi.
edit. I forgot to mention that if you buy your mac and try to open it you will void the warranty.

Which is the better option for using windows on mac ...parallel or vm ware fusion

i want to use c# ,.net, c++ , on my macbook pro ....which software i should purchase parallel or vmware fusion

They both work well. I like Fusion. Others like Parallels. Still others like VirtualBox.
They all have free trials, VirtualBox is a free product, so try them for yourself and stick with the one that works best for you.
I opted to install Windows using Boot Camp Assistant.

Which is the better app for devloping a freelance design website?

Hey Forum
I'm putting together a website for my freelance design business. I've rough out the site, but now I'm stuck between using Dreamweaver or Flash. The site is relatively simple with the common home, about, philosophy portfolio and contact pages. I know that Dreamweaver is a real workhorse and is very stable. But as a designer I want a little more glitz and freedom which Flash seems to have. If I do use Flash, I'm worried about bandwidth, search capabilities and device compatibilities.
Any insight would very helpful
KatyDad

The stability of Dreamweavere will have no little bearing on the stability of your web site--Dreamweaver provides tools, it doesn't teach you how/when to use them. Your decision on which way to go should be based on what it is you are trying to sell. If you are selling web site design, then you may want to temper things towards a non-Flash design base so that you can demonstrate your coding skills alongside the graphics aspects of it. If you are selling Flash-based designs, then Flash would be a good vehicle to demo the work itself. If Flash is not a big part of what you are selling, then it should not be a big part of what you put on display. But you can always mix things up, showing Flash elements and html/css elements, if the intention is to show well-rounded skills across the design options palette.

Which is the better format for message handling - flat files or SOAP?

We have the possibility to specify from our EDI partner how to send messages into XI. We can ask them to send the messages in as SOAP or flat files.
Is there a definite preference for one format over the other? Can somebody advise with reasons?
BR,
Tony.

>>We have the possibility to specify from our EDI partner how to send messages into XI. We can ask them to send the messages in as SOAP or flat files.
I would strongly suggest you go with SOAP rather than File.
Reason : In case of file, the EDI partner will send a file to a machine in your network where FTP server is running and you make your XI server poll the particular folder every 10 min or so. But in case of SOAP, the <b>communication is real time</b>. Your EDI partner can invoke either the SOAP adapter directly or send a SOAP msg directly to Integration Server.
Just my ideas.

Which is a better Platform for SAP

Hi Guys,
Please provide suggestions for choosing the platform for our SAP Projects. We want to know the Pros & Cons between Windows & Unix ( HP-UX or IBM-AIX). Is there any standard tool where we can enter the Operating system & Databas and number of users and therefore estimate the cost and performance difference between Unix & Windows Boxes.

Hi
I am not expert in this area. As per my knowledge, Unix is more secured than Windows. Please post this question in relavant forum to get all the details.

I am a sophomore in high school and i am between getting an ipad with a great quality keyboard case or an 11 inch macbook air. Which is a better suited purchase? I do not want to make the wrong purchase!

I would like some input on which might be better suited for a sophmore in high school because I do not want to make the wrong purchase. I have apple products so I know how they work, so I have no problem in that area!

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
The iPad does not do Java or Flash. So you may have issues using it on many websites. There are web browsers for iPad that try to be work arounds for this, there is mixed reviews as to how well that they work.

For uninstall or to remove Logic Express 8-0-2

Concerning Logic Express 8.0.2:
I want to remove my PowerBook PC G4, the application Logic Express 8.0.2 which currently takes too much space to me and of which I do not have the utility of it.
With this intention; I made:
- Firstly: I removed the application Logic Express of “APPLICATIONS” Macintosh HD.
- Secondly: I removed in LIBRARY SUPPORT APPLICATION file LOGIC.
Into final, I note that there remains to me still an occupation of memory of Software LOGIC EXPRESS, approximately 2.5 Gigas which I do not manage to find and to remove.
Can-you like it, to help me and to indicate to me in which files these relative informations for a total uninstall of LOGIC EXPRESS.
Where then I to find the 2.5 Gigas which is still in my system?
For your information, I do not have any project of creates with the application Logic Express which I never used.
Thank you.

This [thread|http://www.macosxaudio.com/forums/viewtopic.php?f=2&t=45428] gives a list of all the support files and where they are.
Most of your lost HD space is probably Apple loops: if you're planning on using Garage Band, you'll need them but if not, you can trash all the loops too.

Which tool is better for ETL?

I want to transfer data from RLDB to Essbase, there are many method and tools, I don't know which tool is better for my case. Now, what I am doing now is:
1. Create views in Oracle
2. Export view to falt file
3. Import flat file to Essbase using rule file and MaxL import script.
4.The data size: flat file rows 3-4 million, time used: 13 hours
I want to use more powerful ETL tools, such as: Informatica PowerCenter, OBIEE, FDM, EIS, ..., I have basic knowledge for the above tools, but don't know which tool is better for my case? Please advise?

First to streamline your existing process, you could get rid of step 2 and add a odbc connection to the server and Sql statement to the load rule to pull directly from your Oracle database. Of course with the number of rows you have, if you use the same extract multiple times, I would create a table to load into from the view and pull from that table.
As for using an etl (Elt) tool, Informatica is pretty powerful and there is a version of it (although not supported in the future called DIM). I might go the ELT route with ODI(Oracle Data Integrator). In the future I might use OBIEE, but I don't think it fully ready for Essbase until the next version and I don't think it will rank on the same level as a full ETL tool for conversions.
Edited by: GlennS_2 on Jan 2, 2010 9:58 AM
As for EIS, I would not use it, but might use Essbase Studio. (It can use OBIEE as a source) again this is not an etl tool, it would just take youe existing views and load them.

Why do you need a expensive MacBook Pro?
Your attending high school and unless everyone else is rich also your likely going to be a target by the more poorer students for theft or damage to the machine.
You could keep it home, but if you need it for class then your exposed again.
Also at that age your not very careful yet, a MacBook Pro is a expensive and easily damaged machine.
Unless your made of money and so are others at your school, I would recommned a low profile, just does the job cheap Windows PC.
If it dies, gets lost, stolen or damaged because of your inexperince handling senstivie electronics then it's no big deal.
You can buy a Mac later on when your sure you have a need for it, currently there isn't much advantage of owning a Mac compared to a PC, they do just about the same things now, one just looks prettier than the other.
Since 95% of the world uses Windows PC's your going to have to install Windows on the Mac in order to keep your skills up there or be unemployed, so it's a extra headache and expense.
good luck
