Needed: Book(s) recommendations for beginner, needing to come up to speed for complexity quickly

Hello all,
I've been kind of thrown into the need to learn LV quickly. I've gone through the LV 101 videos, and got a decent start....but need to learn more in-depth quickly. I'm looking maybe for a book on amazon, that will get me as a noob started quickly...but also, something needed beyond just the basics of trying to explain the concept of the front panel and block diagram screens....
I'm needing to get into learning how to wire up things like even structures...being able to allow the user to right click an object on the screen, present a drop down menu, and change the object based on their selection. I've posted here before looking how to do multi-colored indicators..and starting to get a grip on some of that, but still not yet...
I'm looking at an example of an older version of the app I'm trying to create and improve on...and see how they were changing a boolean indicator (they used a round one, but was flat unlike the LED shaped ones)..but they were able to change the colors of the text and control with three different background and text combinations both when it was clicked, and programatically when a trigger was pressed...etc.
I'm seeing a structure they used called a "property node" and using colors under that to change it, it appears....I need to learn to understand that....but the application I have is a bit complex for me to track and figure out everything as it flows....
I thought I'd seen a recommendation for a book on this forum called: Labview for Everyone...but that is dated 2006...would this be too old since I'm working with LabView 2011?
Anyway, I'm looking through all the stuff in the NI site's Knowledgebase....but think getting a quality book that is a bit structured taking me from basics to more complex things would be the best way for me to learn and organize my thoughts.
I've programmed (awhile back) with Delphi for Object Pascal...and some java with Eclipse. But with Delphi, I have worked with an IDE...putting object on a screen, and then setting and programming properties...but LV is a bit different, and I'm just not familiar with all the objects available to me..and the graphical programming rather than writing code in there to handle things..is a bit new to me.
Anyway, hoping ya'll can give me some good book recommendations...and any links to web info greatly appreciated too.
Thank you in advance!!

without giving any special suggestion, i want to point out:
Even "out dated" books can give you valuable information since the programming paradigm of LabVIEW (dataflow) is still valid.
Ok, we have to admit that information on certain elements as well as esp. performance might not be true because of the changes LV had undergone over the years (e.g. compiler changes in LV 2009/2010).
Adding to this, i urge you not only to look for technical expertise but also on "how do i approach a development task". I find this link a helpful source for this.
hope this helps,
Norbert
Thank you for the reply. I'm looking at the link and it looks informative.
I went ahead and bought the book LabView for everyone. One thing however, I read in one review, that the book is light on the topic of event driven vi''s......which is something I'm definitiely needing information on....simple examples would be even better.
Any links or book recommendations on this particular topic?
Thank you,

Is there an utility for monitoring cpu/gpu temperature and fan speed for desektop m9200T?

My desktop computer m9200T running Win7 Home Premium crashes often. It seems to be temperature related.

Hi,
Only have one temperature monitoring application running or you could end up with erroneous readings.
Try PC Wizzard. Depending on your hardware, you should see temperatures for CPU, GPU and disk. At the same site you can also try HW Monitor.
I am running a custom motherboard and it comes with its own software for this purpose. HW Monitor seems fairly complete.

Help for beginner: Need labview signal to power on =2 actuators of 8 with one power supply

I am a beginner in using labview. I need to use labview signal to turn on >=2 ac 8 actuators with one power supply. The 24VDC, 0-3A power supply is enough to drive all 8 actuators which need 24VDC and 0.1A current. So the main function is like turning on 2 or more than 2 switches in series with the 8 actuators with one power supply. Any suggestion of some simple module for this purpose? Thanks.

Maybe I didn't say the question clear. I have one power supply (24VDC, 0-3A) and 8 solenoid valves (24VDC and 0.1A). Two valves (or more than two in future) have to be activated each time. I would like to find something that can work like switches installed in series with the valves. Then I can wire the valves (with the switches) in parallel with the power supply. As I turn the switches on and off with signals from Labview board, power to that specific valve will be turned on and off.
Any advice for this kind of switches or any module that can be controlled by Labview signal? Please help! Thanks.

Need a scanner recommendation for slides

(Not sure if this is the correct forum, but here goes)
Any recommendations for a scanner that will do slides? I've got my father-in-laws slides from the last 20 years and want to scan them, but can't quite figure what scanner would do the job. I don't need (nor want to spend $) on an auto feeder, but would like to be able to scan at least 4 slides at a time. I've got old photos and negatives that I'll be scanning as well, and would spend up to $400. Thanks!!

YMMV but I just finished scanning over 1200 color 35 mm slides from the 60's and 70's for eventual prinitng and use in my scrapbooks. I have an Epson 4870 scanner and I can scan 40 slides an hour using it. It works well. The price is a bit more, $440 or so, but the advantages are worth it.
If you have 2.25 x 2.25 glass slides you will have to build your own slide holder to scan them.
I got the scanner originally for a major scanning project for the local historical society of about 1500 5 x 7 glass plate negatives from the early 1900's. It's doing good archival quality scans of these materials as well as archival scans of our other historical negatives, about 2000 nitrate negatives of our local area. It's a low end professional scanner but IMO worth every penny.
For info on digital imaging help you might want to take a look here:
http://www.cdpheritage.org/
The best practices document on digital imaging is excellent for all the issues you will face and need to deal with. Geared towards historical collections it's still useful for personal stuff.
The Epson SW and scanner works well on the Mac. I just upgraded to Tiger, and it still is working, unlike many other items. <G>
I use Photoshop CS for histogram evaluations, image processing and thumbnail creation for the historical negatives but have just used the files as scanned for my scrapbook images.

Beginner needs suggestions on books.

I am thinking of buying some of Dave Power's books on php and
Dreamweaver. I can cut and paste code and use Dreamweaver, but I
don't really understand what I am doing. I know a lot of code
snippets, but I don't really have a view of the big picture. Here
is how I have been learning: I use Dreamweaver. I look for the item
I want to change, and if I find it I make the changes then see if
it works or if I have broken the site. I have just about reached
the limit on what I can learn using this hit or miss method. Other
than book suggestions, I guess my main question would be "How can I
understand the overall organization and structure of a web site
composed of html files or php files or a combination of the two"?
How are these files related to each other and why are they in
separate files to begin with? Why isn't a web site one giant file?
I give two examples here:
Example1: I know an html web site is made of pages and I have
no trouble making one. I just have to have an index.html page which
links to other pages which I can call whatever I want such as
products.html or whatever. To me all such html pages (at least the
files I make) are clones of each other except for content changes.
In php this simple file to file or page to page relationship is not
evident. I see things like configure.php and folder named includes
(whatever that means). I need to understand the entire web site
package if I am to make any sense of how each of these individual
files work together. And why have a folder named "incudes" anyway?
Why aren't all the files in the same folder? How can I know that
changing one enigmatically named php file will affect other files
not even in the same directory?
Example 2: Where on the server do these files go and why? I
just found out about .htaccess in order to password protect a
directory on a web site but I don't what that is exactly and how it
works, where it is placed, or how to create it. I asked my host
admin person to create it for me and he did. I see some .htaccess
files but I don't know why they are there in such and such a
folder. When I open it, the contents mean nothing to me.
So what books can unveil the mystery of html, php, and where
on the server these files go and why? I can already upload a web
site I created via ftp to a server, but I don't understand why I am
putting it where I am told to put it. Although I can usually figure
out and use the server path names or directory naming schemes, I
don't really understand them or how they work. I would prefer to
buy e-Books if possible so I can view them immediately.

I'm not quite sure when it was released as an e-book, but it
was some
time in the second half of last year. "Foundation PHP for

came out when Apress was experimenting with e-book versions,
and it
somehow got left behind. I think that all new friends of ED
books are
now released simultaneously in paper and e-book versions.

Varifocal lenses are the answer. :-)
Seriously, though, it seems as though many people like having
both paper
and electronic versions of a book. I don't know if you have
"PHP
Solutions", but the final page gives details of how to get a
discount on
the e-book version. Apparently, you need a copy of "PHP
Solutions" with
you when ordering the e-book version, because you get 60
seconds to
answer a question related to the book to qualify for the
discount.
The e-book versions are available only from the Apress
website. You
can't get them from Amazon.

I need forum for beginner learner in inventory purchase and SCM modules

I need forum for beginner learner in inventory purchase and SCM modules

Saging,
Hmmm. It seems a bit odd to be creating a 'forecasting-of-material-procurement' tool, when SAP has so many already built in, either within ERP or within APO. Oh well, I am sure there must be a good reason.
I have seen from our systems that most loads come from APO going to BI. Is it always that way?
BI type data can come from any source. The most common BI solutions I have seen is where BI data are extracted from the main ERP. However, the beauty of BI is that it doesn't care, SAP builds in functionality to get data from anywhere.
Are data from ECC considered as well?
They can be if you design it so.
You should be aware that most data existing in ERP that are relevant for material planning also usually exist in APO. The Core Interface between ERP and APO is normally set up to natively replicate substantial quantities of Master data and also transactional data. It may be that in your business environment, you really don't need to connect to anything other than APO. However, this is not a limitation of BI, it is just smart programming to try to minimize the number of sources of your data.

Need a product recommendation for small network

Hello All!
I just started a small computer and network consulting company (in addition to my "day job"). I work for a huge company with several hundred sites, all Cisco networking of course. I am also setting up a small network and computer consulting company to do on the side and will be dealing with small companies and helping them with their network needs. Anyway, I am looking for a entry level Cisco product because my Linksys just isn't going to cut it any more. I want to set up 3 servers and I currently have 5 static IP's from Comcast. I want something that would operate like a PIX515 firewall but that would obviously be overkill for what I am doing. I want the capability to set up port forwarding to the inside from my 5 external IP's. Wi-Fi isn't critical but would be a "nice to have" if it didn't cost too much more. What would be a good product for my needs? I want a NICE CISCO product but not an EXPENSIVE one, either. I am also interested in certification and possibly becoming a VAR soon. Any pointers would be much appreciated.
Thanks,
--GREG--

I would steer clear of the 500 express. Since you seem to be new to cisco products, I would use the opportunity and buy what most of your potential customers already have. Get yourself a pix/asa and a 2900 series switch as first poster suggested. If you are interested in certifications, you will need to learn the command line interface. The 500 express will do you no good as it is all gui. This is only my opinion of course. Oh, and did I see not expensive and cisco in the same sentence. :)

*SCANNING SLIDES- PLEASE RECOMMEND SCANNER/EQUIPMENT NEEDED

Hello,
I used to have the HP Scanjet 4470c which came with a slide/photo-negative adapter. First question, is this compatable with my Mac OS X Version 10.4.8?
When I got the Mac, I purchased the Canon Pixma MP500. This doesn't seem to have the option to scan my old slides.
If you would, kindly let me know what I need to do to properly scan my slides to import to IPhoto- can I update anything, use a third party, or do I need to purchase a third scanner?
Thanks so much in advance for your assistance.
Take care,
Michael

Sieb:
Welcome to the Apple Discussions. According to HP's web site the 4470c is not compatible with OS X.
So it looks like you'll need a new scanner as the multifunction Canon doesn't fit the bill. I just bought a Canon 8600F and it has slide capability. Canon has 2 models with that capability ( also the 4400F model). Both will do 4 slides at a time. If doing more than 4 at a time then look into other scanner brands.
With the scanner I just purchased I got Photoshop Elements 4 bundled with it. That's a good add-on.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Have been using good ole cannons from 70 h 80's for years.Need to update and understand new technolo

Have been using the cannons for many years mostly scenic areas. Quit using them eight years past.
I am retired and need to update and understand what you have so l can start over.Thanks for your help, Edgar.

Hi Edgar,
While there are occasional Canon tech wizards on here to help out, mostly it's conversations among Canon users.
You are basically wanting to go from film to digital, which can be both easy and very, very complex. Some of the modern DSLRs can be used in a highly automated, almost "point n shoot" manner. Or you can get as involved in using them as you wish, using less of the automation, usually with more consistent and pleasing results... but a much steeper learning curve.
If your Canon are from the 70s and 80s, they are manual focus lenses and cameras with the FD mount. Some of those were fantastic, but simply aren't usable on modern Canon, which use EF mount. So you are most likely starting from scratch.
I'd recommend one of the more entry-level models, perhaps with one or two kit lenses to get started learning to shoot digital. But it sort of depends upon your budget, how much you want to spend. I don't know where you are in the world... I'm in the US so below I'm refering to the current US model designations Canon offers (and international designations are in parens). All these models are "EOS".
The Canon Rebel T3 (1100D) is the most entry level model. If bought in kit, it usually comes with EF 18-55mm lens.
Rebel SL1 (100D) is a very compact camera, in kit usually comes with 18-55mm lens.
Rebel T3i (600D) is a bit larger and adds some features... in kit it's often offered with 18-55mm, or sometimes with 18-135mm, or sometimes in a 2-lens kit with 18-55mm and 55-250mm.
Rebel T5i (700D) is the top of the Rebel series line and mostly adds features related to videography. It can be found in kit with the same options as the T3i.
EOS 60D is a mid-grade model, using a true pentaprism (the Rebel series use a penta-mirror). With higher top shutter speed (1/8000 vs 1/4000 on the Rebels), somewhat different controls (more direct access to things commonly used by more advanced photographers). The 60D is being discontinued right now, but you will still see a lot of them in stores.
All the above have essentially the same "APS-C size" 18MP sensor (except T3/1100D which uses a 15MP sensor). T5i and 60D have a similar, more advanced autofocus system.
EOS 70D is the new model that's replacing the 60D, has a new 20MP sensor, as well as a more sophisticated autofocus system than any of the above.
60D and 70D in kit usually come with 18-135mm lens, but sometimes there are alternatives.
The EOS 7D is the top of the line APS-C size sensor, a fairly pro-oriented camera with less support for new digital shooters, a sophisticated and fast autofocus system. .
Finally there are also and so-called "full frame models EOS 6D, 5D Mark III and 1DX (sensor is 24x36mm, same image size as most 35mm film cameras shoot). The 6D is essentially an entry-level, more compact full frame model. 5D Mark III is a mid-grade model, and the 1DX is an uber expensive pro-oriented, high speed model. You might be tempted by these initially, coming from film cameras. But be aware they not only cost more initially, are a bit more limited in lens choices, plus the lenses for them will generally tend to be larger, heavier and more expensive. The APS-C or "crop sensor" models can use all EF and all EF-S lenses. While the "full frame" models can only use EF lenses. EF-S lenses are specifically designed for crop sensor cameras. EF lenses were designed for film or have been designed for full frame, but are also fully usable on crop cameras. So, crop cameras can essentially use any lens Canon has made since around 1990 and onward.
I'd recommend you start with one of the crop sensor models.... graduate later to one of the full frame models, if you find that necessary. Today's crop sensor cameras are actually quite capable. You can make a pretty large print from them, with little loss of image quality. You'll just have to "re-think" focal lengths, from what you are accustomed to. For example, a 50mm lens on a crop sensor camera is no longer a "standard" lens. It acts more as a short telephoto, like an 80mm would on your film cameras (nice for portraits). If you want a standard lens on a crop sensor camera, you'll want something around 30mm. The 18-55mm kit lenses, for example, cover approx. the same angle of view range as a 28-90mm zoom would on your film cameras.
Now, seeing that you are an experienced SLR user, you probably don't need the automation and newbie support of some of the most entry-level models. But also going from manual focus to autofocus (which, when used right is faster and more accurate than I ever was with manual focus, and I was pretty good!)... I'd suggest starting out with one of the simpler AF systems.
The T5i or 60D might be good choices for you. Go compare in a store, if at all possible.
Just as was true in the days of film, lenses still tend to make more of a difference than the camera they are used upon. In other words, the entry level kit lenses might be a low cost way to get into modern, autofocus, digital cameras... but if you're budget allows you might want to consider some more advanced lenses. In the kit lenses, I would recommend the "STM" (stepper motor autofocus drive) models... they are the latest and greatest. But there are even better, in particular the USM (ultrasonic motor autofocus drive) which are often found in otherwise upgraded lenses. For example, for crop cameras there are the EF-S 10-22mm, EF-S 15-85mm USM, EF-S 17-55/2.8 USM and EF 70-200/4L USM lenses. These are fast and accurate focusing, with top quality optics. Most of these lenses also have or are optionally available with Image Stabilization (IS), which is great and allows handheld shots that were near impossible with your older gear. Highly recommended.
Shop around and don't forget to allow some room in your budget for other necessities. You'll need memory cards (the entry level models and T5i, 60D that I recommended all use "SD/SDHC" memory cards). You also might want a spare camera battery (most entry level models use LP-E8, the 60D uses the larger LP-E6 to get about twice as many shots per charge). There are also accessory battery grips available for most models mentioned, which give secondary controls that are nice when shooting with the camera in portrait orientation, as well as adding a second battery to double the number of shots you can take. Most of the lenses mentioned don't include the lens hood, which I highly recommend buying, too.
All these Canon cameras come with a complete software suite, all you really need to get started cataloging and editing your images on your computer (some other manufacturers sell certain softwares separately). However you still might want to look into some third party softwares. Adobe Elements is an excellent and affordable introduction to Photoshop, which is arguably the "big daddy" of all image editing softwares. There are others... some cheaper, even some free... and you don't really need to rush into adding softwares unless you simply want to. The included Canon software is fine to get started.
I guarantee you will find yourself shooting a lot more digital images, than you ever did with film. For one, after the initial cost of the camera, lenses and basic gear, you will feel like "shooting digital is free!". It's not really (camera and memory wear out eventually, upgrades come along, and digital storage & backup fill up rather quickly). But it's certainly cheaper than shooting film. Last time I shot a lot of film I figured it cost a minimum of 50 to 75 cents per shot (common 35mm film with local, consumer grade processing, 4x6 prints or contact sheets... $15 to $20 per 36 exposure film). Digital reduces that to around 5 cents per shot, on average.
You'll also love high ISO shooting with your new DSLR. Any of the above cameras can be used at ISO 1600 with much better results than any film at that rating. With a little extra work, ISO 3200 and 6400 are quite usable... perhaps even higher! I rarely use lower than ISO 200 now, where with film the bulk of my work was at ISO 50 and 100.
You also will enjoy the immediate feedback you get being able to review your images on the spot, right on the LCD screen on the back of the camera. The histogram, in particular, is very helpful once you learn to use it. Heck, you can even shoot tethered to a computer and see your images full size on a computer monitor immediately, if you wish... Or download them and view them just minutes after pressing the shutter release button!
Get some books about digital photography. In addition to something more general, I also highly recommend getting one of the guide books specific to whatever camera model you choose. That will complement the manual that comes with the camera. If you get an image editing/cataloging software, I'd recommend a book specifically for that, too. Another book I recommend is "The DAM Book - Digital Asset Management for Photographers"... which can be found and bought online. It's very helpful setting up your "workflow", and the sooner you do that, the better (it's the pits having to go back, reorganize and potentially redo thousands or hundreds of thousands of images).
There are also good online tutorials about many aspects of digital photography. For example, I highly recommend the three half-hour videos on YouTube about Canon autofocus systems and how to get the best results with them... beginning with this one: http://www.youtube.com/watch?v=iAx86nblZ2g This is a few years old now, but still quite relevant... the 50D is discussed at length, but it uses an AF system that's virtually identical to the 60D, for example. It also might help to know some of the features of the more recent, more spphisticated AF systems, which are discussed a bit. There are other videos and online tutorials at the Canon Learning Center, on YouTube, and elsewhere. Some are model specific... such as the AF system of the 7D (which is largely carried over into the 70D now).... and the even more advanced 5D Mark III/1DX AF system.
Other users here and at other forums online can be a big help, too. Don't be afraid to ask questions (we've all been there at one time or another).

Java2D beginner needs advice

Hello,
I am a Java developer who needs to use the Java2D API in order to draw a shape similar to the following png:
[http://www.emeraldinsight.com/fig/1120220203017.png|http://www.emeraldinsight.com/fig/1120220203017.png]
I have never used drawing APIs and therefore would be very grateful for general guidelines as to how to go about drawing this particular shape - which is a binomial tree.
Thanks in advance,
Julien.
ps. I have read the tutorial and will use it
Edited by: balteo on Nov 8, 2009 2:13 PM

I would make it a two-step deal.
The first step is to create an in-memory data structure that represents the tree you want to draw. This is something you can unit test. You would only need to define the nodes, the lines you draw between the nodes.
The second step is to actually draw the tree. Create a subclass of JPanel and override its paintComponent() method. In here you do the drawing. This is an iterative process.
- first draw the circles
- then draw simple lines between the circles. Use the center of the circles as the endpoint for the lines. If you draw the lines first and then the circles, the lines will appear to end when they hit the circle.
- add the text to the nodes
- finally do the pretty up step, making arrows out of the lines. This requires some math to figure out where a line hits the circle.
I would recommend the book [filthy rich clients|http://www.amazon.com/Filthy-Rich-Clients-Developing-Applications/dp/0132413930/] for in-depth information about Java2D drawing.

I have a iMac 21,5" Intel mid 2011 and I need to know if is possible I change the original 500Gb HD for a 512Gb SSD? If yes, where I find a tutorial about this? Thanks a lot and best regards all.

Hi people,
I'm typing from Brasil, sorry my English.
I have a iMac 21,5" Intel mid 2011 and I need to know if is possible I change the original 500Gb HD for a 512Gb SSD?
I intend to keep the original DVD driver and install the SSD in the same HD place.
If yes, where I find a tutorial about this?
And I will like to know if the 512GB Solid-State Drive Kit for Mac Pro is compatible with iMac.

What brand and model of SSD do you recommend?
Thanks a lot for now and best regards all.

Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM.
This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor.
Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable.
When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive.
If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. Resetting the SMC (System Management Controller) will have a temporary effect, but again the fan will speed up.
Fixes people have used in the past included:
Using smcFanControl and the terminal to set a MAX speed for the fan and writing scripts to start this after every sleep/restart.
Shorting the temperature sensor cable (Not a possibility on 2011 iMacs) this tricks the iMac into thinking the drives temperature is very low, hence slow fan speed.
Both these fixes are less then perfect and leave the drive in a dangerous situation with no protection from overheating.
Another option people try is other Fan Control software. These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.
HDD Fan Control
HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.
It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating
Instead of HDDFan Control, get the free SSDFan Control

Which rMBP for my needs? 13" or 15" rMBP

Hi,
I've read several threads and articles and can't seem to find any reviews for folks w/ a similar setup. Most reviews are for a the laptops themselves but I'm curious if anyone can chime in on the performance when connected to a 27" Apple display (pre or post thunderbolt). How does a 13" rMBP perform in iPhoto/Lightroom/Photoshop on a 27" apply display?
Here's some background. I'm currently using a 2010 15" MBP connected to a 2010 27" Apple cinema display (pre-thunderbolt) and performance really bogs down in iPhoto (150GB iPhoto size). Performance is much, much better when not using the 27" display.
My current and future uses are iPhoto and iMovie. I use a Canon 7D DSLR mostly for pics and HD vids of my friends and family. I plan to purchase either Aperture or Lightroom once I get a new rMBP as well. I shoot RAW files and use the HD video features.
Can anyone chime in and/or make a recommendation as to which rMBP would be best for my uses? I like the price and form factor of the 13" rMBP but my main concern is it doesn't have enough horsepower to drive a 27" apple cinema display.
I have both a 2008 13" aluminum macbook, 2010 15" MBP, 2011 MBA, and all work like champs - when standalone. It's just that they don't seem to be able to handle 27" apple display all too well (i.e. scroll lag, choppiness when dragging windows, iPhoto slider update lag, etc). The 2008" 13 aluminum macbook can only watch Bloomberg TV standalone, on the 27" display it's blank. My work laptop (2011 Lenovo ThinkPad) handles the 27" display like a boss!!
With that said, unfortunately, for my needs I feel like it's time to upgrade (again) and now leaning more towards the 15" rMBP. But if the 13" rMBP can handle large RAW files, HD vids, AND a 27" cinema display I'll get that one.
Any help is greatly appreciated. Thanks so much!

I also use a Canon 7D. One big difference is that the current 13" and 15" have Intel Iris/Iris Pro integrated graphics, which are said to be a great improvement over the integrated graphics in the older MacBooks you have. They are so much better that Apple no longer sells MacBook Pros with a separate graphics card unless you buy the most expensive 15" MacBook Pro, which is so expensive I'm not sure I'll ever buy it.
For Aperture or Lightroom, the amount of RAM is going to be very important. I don't use Aperture, but for Lightroom the graphics card is not very important. From that I would guess that you could get either a 13" or 15" as long as you put enough RAM into it from the beginning, since both programs want lots of RAM and you can't upgrade it later. That should be at least 8GB RAM, but I would just max it out at 16GB RAM and not worry about it again.
The current 15" should drive a 27" monitor without a problem. I'd like to say the 13" can, but since it's labeled Iris instead of Iris Pro that might make a difference. If you live anywhere near an Apple Store you should go down there and ask them to connect the 13" to one of their 27" monitors and see how well everything works.

I have Acrobat Pro 9.0. Am happy with it since I only have occasional need. Haven't updated it. Is there a way to do this? Do I need toy go through updates sequentially if they are available? Thanks for any help.

Hi Spiral Geronimo,
It is always recommended to update the software to its latest updates. I would suggest you to update your Acrobat 9 to its latest updates. You can download the updates from the link below:
