Needs some advice on Macbook Pro configuration

I am using the Macbook for personal use and ocassionally for work. I will need to install either VM Fusion or Parallel Desktop to run Windows 7 and I occassionally need to do work on an application that runs on Internet Explorer only (online application, no heavy graphics).
I really like the portability of the 13" model but I am afraid dual core processor is not powerful enough if from time to time I need to run Windows 7 under virtaulized environment.
Is it better if I go for 15"? If so is 2.3 GHz enough or I need a 2.6 GHz processor? I plan to have 8GB RAM.
Thanks.

I've ran Fusion on a 2008 15" Macbook Pro. It has a Core 2 Duo, 8GB DDR3 RAM, and 750GB Seagate Momentus XT Hard Disk (hybrid SSD/HDD). I did experience slow-down when running multiple apps (iTunes, Chrome, Mail, Office, occasionally photoshop and xcode) on OSX, while running a couple apps on a Windows 7 VM with a single processor. The 8GB of RAM was enough, but more cores were needed for it to run smoothly. I now have a 2011 15" MBP with 16GB RAM and a 512GB SSD. I don't think I've ever experienced slowdown, even when running two VM's alongside OSX.
Ask any IT Admin about running VM's, and they'll tell you the more cores the better. With VM's, it not as much about clock speed, but about how many simultaneous processing tasks you can handle.
...and now to go against what I've said. Having said all that, if you're running standard tasks on OSX, and just running IE on the VM, then the 13" with the dual-core hyperthreaded i7 would probably be fine. I was running quite a bit of stuff on my 08' MBP. Part of the slowdown I experienced was probably due to simultaneous disk access from osx and the VM as well.

Need some advice from MacBook Pro users

Hi all. I've been using Windows for as long as I've ever owned a computer. I have a background in graphic design and finally came down to needing a notebook. After some careful consideration I've decided to go with a Mac. I have used them before in the past on job and off and I've had some bad and good experiences with the Mac.
What I am trying to figure out is I have heard the Macbook pro has some heating issues. I am also not sure if I really need the macbook pro. I could easily just use the 13' inch without the graphic card. What I typically do is design in photoshop, dreamweaver, surf the net, etc. Basically it is a business computer. I don't use it to play games and as such I want to make sure I am making the right choice.
Is the Macbook 15' right for me? I am worried about over heating issues.
Also I could easily buy the 13' and just bump the ram to 2 gigs. I just wanted to see what everyone thought. Any advice?

I just updated to the MacBook Pro 15 from a PowerBook 12, the MBP does seem a bit hotter than the PB but its not that bad of a problem, at least not when using Photoshop and Illustrator.
However, in terms of design, if you will be using the notebook as yoru primary design machine without an external monitor, the MBP 15 would be a much better choice. I'm an art director and I only use the notebook when I'm on location, most of the actual design work is still done on a G5 desktop. The MBP's screen is actually big enough to be productive in Photoshop and other design software, but the smaller screens like 13" can be a bit tough on the eye in the long term, managing screen real estate can also be annoying. Not to mention, the new glossy screen is very beautiful.

Need your advices on MacBook Pro Retina

Hi all !
I'm in the market for getting a new laptop.
To put you in context, I'm a student studying electronics. Normally, I know what I'm talking about ;-) lol
I work as a park supervisor. I could not get a better summer job since I can study while working ! Every day, I sits in the park, turn on my laptop and start coding, reading and studying. Being paid to study is sincerly amazing ! ahah !
So, I study most of the time in the park, on my laptop.
I also have a powerful workstation (Asus P8P67 WS Revolution, Core i7 2700K 4.5 GHz, Asus GeForce GTX 680 DirectCUII, 16 GB RAM, RAID 0 SSD, a beautiful monster) for long works and coding session. I also do a lot of virtualization with VMWare Workstation. In fact, I've built a virtualization concept which segregates each tasks in different VMs.
But, my laptop is an essential tool for me because I use it as much as my workstation. I'm used to carry it at school and at work. So usage is about 50/50 between my Workstation and my laptop.
I started learning the CUDA API and massively parrallel programming. I bought the Cuda By Example book ( http://www.amazon.ca/CUDA-Example-Introduction-General-Purpose-Programming/dp/01 31387685 ). My Asus UL30VT has a CUDA-Capable GPU in it, along with the integrated Intel chipset. So I setup everything for Visual Studio, install the nVIDIA SDK, and start programming.
Here comes the trouble.
Neither Visual Studio nor the nVIDIA SDK (which contains code samples) see the GeForce G210M in my laptop.
I searched a little over the internet and found that the integration of the graphics processors in this laptop is the worst kind of integration ever built in a laptop. The GPU switching technology is the "beta" version of the nVIDIA Optimus technology. The video drivers are more than obselete (197.xx driver version!!!!) and no more recent version is available, even with tweaks.
Absolutely no CUDA code would run in my laptop.
Sure, I could code on my workstation. But it's summer, and being stuck in the house basement while it's sunny outside ... ***** ... lol
And as I said, since I study most of the time (~90%) in my park, it's not very usefull to have a laptop that cannot do what you want anymore...
So I started my research to find a new laptop that would fit my needs. Easier to say than to do...
There is one month, Apple has announced the new MacBook Pro 15 Retina Edition.
I went in an Apple Store to take a look at these nothing else than piece of art.
And you'll guess it : I've fallen in love with this machine.
Thin, lightweight, good battery life, incredible display, amazing hardware. Everything on this laptop is incredible. Even the price ..................
Sure, the non-retina display is also a good machine, but being used to an ultraportable laptop (pre-ultrabook fashion), I would like it to be has thin and light as possible. And the non-retina has less high-end hardware too...
Since I saw this machine, the idea of getting one haunts me!
I tell myself that I could do more shots with one rock. I could learn the OS X environment which is, according to everyone who has an Apple computer, the best working environment ever created. And since I do a lot of virtualization but never could do this with my ultra-low-voltage CPU, the MacBook would also enable this possibility.
More and more programmers are adopting OS X to code. nVIDIA has also said that the new MacBook is one of the best CUDA development platform.
( http://blogs.nvidia.com/2012/06/new-macbook-pros-make-for-great-cuda-dev-platfor ms/ ). Sure, I have a long road to go throught before being a real developper, but as you might have seen, I like to work on things that really work well.
So, the 2700$-question : according to you and all the details I wrote here, does a MacBook Pro would be a nice choice for me ?
For this price (in Canadian dollars, I live in Montreal, Quebec), I have the MacBook, the Apple Care for 3 years and VMWare Fusion. It's a 400$-discount that I get because I'm a student (200$ on the machine, 100 $ on the Apple Care, and a 100$ gift card to get the iWork Suite and other softwares if needed).
The Non-Retina model is not an option, since I must upgrade it with SSD, 8 GB RAM et would like a better screen resolution. With all these upgrades, it's even pricier than the Retina which come more equiped.
I've looked to other laptop manufacturers too. Dell offers the XPS 15, but it's bulkier, doesn't feature has much as the MacBook, and I would not pay 1900 $ for a "Dell"......... Lenovo makes great laptop too, but I don't know ... Thinkpad are sure the reference as business laptops, but are heavy and bulky. Maybe I've missed a model... The IdeaPad is a nice ultrabook, but once again, it's an Ultra low voltage CPU, so virtualization would be so-so I guess... And Asus has nothing really exciting avalaible at NCIX (the main Asus online reseller in Canada and also the online shop where I buy all my system components).
One other thing : with all non-Mac laptops, I'm at the "mercy" of the manufacturer regarding GPU drivers, just like my Asus UL30VT... Most of the time, the Verde drivers would not install and you get the very nice message "Please refere to your laptop manufacturer for drivers" ......... -_-"
I request your experience and advice to clarify my choice.
Thank you very much !!!

I was going to try to convince you to go with a PC notebook, but I know nothing about them. As you're concerned about weight, CUDA development, etc., I think that the MBP-R would be an excellent choice. I'm in a wheelchair and carry my MBP around in my backpack on back of my chair, so I don't worry about weight too often...
It sounds as if you're bright enough to be able to learn new things quickly, so there's no need, I think, to go with the usual "if you're already familiar with Windows, why not... etc."
It also sounds as if you've both thought things through and have decided on what you need. My opinion? Go with your gut feelings and thoughts. Just remember that you're going to be on the bleeding edge, somewhat. There are some here who have had problems with their new MBP's - and not just the Retina models. But then, we don't hear about the thousands (tens of thousands?) out there who are having no problems.
Three things to remember - if you have trouble with your new computer during the first two weeks, Apple will replace it, refund your money, whatever. Second, AppleCare (which I always buy) extends your one year warranty and 90-day phone support to a three year warranty with three years of phone support. And third, this is a large community and there will always be someone here who can help you through minor glitches you may have.
Go with your gut - get that new MacBook Pro with Retina display. I'm sure that you'll be happy with it. I would go ahead, though, and pay the $79 for the external USB SuperDrive - not to carry around with you but just as insurance should you ever need an optical drive.
Best of luck,
Clinton

Need some help with Macbook Pro A1260

I purchased a non working MacBook Pro from Ebay as way to try out servicing Apple hardware along with the Windows hardware I service.
I have been able to get the laptop to power up, but only in an odd way. By reflowing the logic board it will now start up, but only in certain order.
If I reset the SMC by pressing the power button for 20 seconds and than connect the power supply and still holding in the power button for an additional 20 seconds it starts when I release the power button. I can turn it off and on until I unplug it and plug it back in. When I do that it will not start again, if I perform the same SMC reset procedure it will work and turn on. During this time the light on the power connector is off. When it is LIT it will not start. I also get just a white screen and no Apple logo. It will also boot directly from the harddrive. The problem is that the drive is a windows OS drive. I put the drive in to see if the logic board would see it.
This machine was shipped to me without the hard drive and without the recovery disks.
Now as I understand it, unlike Windows and Linux you cannot boot from an install disk for the OS with an Apple product, is that correct? That means I'm stuck here without the recovery disks?
When I first reflowed the logic board it booted to the apple logo then asked what to boot. It seemed to boot fine and show the apple logo a couple times but now it is not. I did start it up prior to getting it completely installed in the machine. Should I try the reflow again? Is it possible to get the recovery disks from Apple? The apple store near by was not very helpful. The person at the door was a little condescending, "it's nice to try and save a little money", "wow that's an old piece of hardware", He totally missed the point that this an exercise in education. I'm trying to learn how to help people when they cannot afford to purchase a new machine. The same thing I do for Windows PC users.
Thank you for any and all suggestions and assistance. I look forward to recovering this and checking out what the Mac users have telling me for years.

Ogelthorpe suggested that I add my two cents here.
This site is a wonderful accurate resource for a Lot of information about every Mac ever issued. The link is directly to the MacBook you seem to have:
http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-2-duo-2 .4-15-early-2008-penryn-specs.html
Your Mac initially runs the Power On Self Test. When that test passes, the chime is generated by software. If a reliable source of software can be found, booting is likely. If it fails only due to memory, the power light will flash a deliberate pattern (not just flickering), and it may also beep in a similar fashion. This indicates "not enough working RAM to start up", so in some cases, you will want to remove all the memory and look for those flashes.
The simplest boot-up procedure any Mac can do is to boot up while you hold the Alt/Option key. This runs a ROM-resident routine which draws a pale blue or gray screen, and over the next several minutes, explores all possible addresses looking for all possible appropriate source of appropriate software. If any are found, an Icon is drawn for each, and its name will be listed underneath. The mouse can be used to select one and click the arrow to proceed. Mac OS X can boot from any attached device, such as a USB stick or external (self-powered) DVD Reader or External Hard Drive.
The gray Apple in not resident inside your Mac's Hardware. Its loading indicates an appropriate source of software was found, and the first blocks of the boot loader were successfully transferred into memory. Hanging with the gray Apple on the screen indicates it failed while trying to run the loaded blocks of the Boot Loader. With certain extremely rare graphics issues, the gray Apple can appear scrambled like a puzzle.
Many system functions, including fan and temperature control, charging, system clock generation and low level inputs such as keyboard presses are handled by the System Management Controller SMC. Resetting the SMC in case it has gotten into an odd state is vital to debugging.
Intel-based Macs: Resetting the System Management Controller (SMC)
If you removed the motherboard for baking, you may have seen the MagSafe charge board. These sometimes need replacement if there have been serious power problems previously, and are available as spare parts from the sources mentioned in posts above. Most other components are soldered in place, and in much later models, the RAM chips are soldered in place as well.
Mac OS X 10.6 uses the Installer/Utilities DVD to do auxiliary functions. Once you move to 10.7 and beyond, these are moved to the Recovery_HD partition on the Hard drive. Once installed, you can copy your Recovery_HD to a 1 GB USB stick using an Apple Utility, which can be booted independently. Macs after about 2011 (except the silver tower Mac Pro) have added the ability in firmware to get this stuff off the Internet via common WiFi set-ups. They can, from a cold dead start, download the stuff needed for Utilities and Installs.
If you download 10.7 or later form the Mac App store, you can make an Installer/Utilities USB stick on an 8GB stick. Making a dual-layer DVD is also possible, but is not as popular because it takes so long to boot up and install off a DVD. You must intervene in the process to make such an image. It must be done after the download is complete, and before the Installation has finished, because the Install package is deleted at the end of the Install. You can steer this or any Install to nay attached and properly-initialized drive.
There is no EXPLICIT copy protection on Mac OS X tools and images, but when downloaded, all will be tagged with the Apple-ID you supplied, and any re-load will require that same Apple-ID and password, or the new owner will need to download their own fresh copy using their own Apple-ID. If you are working mostly for a single client organization, you can ask them to provide their preferred Apple-ID, or create one and provide it to them to be used for their overall Mac APP Store purchases. Once purchased (even for $0), items in the Mac App Store appear on the Purchases page of the logged in Apple-ID, promised as "forever".
Windows does not believe there are any other Operating Systems in existence, so it limits you to booting from the Internal drive, limits the number of partitions that can be created to a total of four, and as its crowning achievement: should you use ANY Windows tools to directly modify or even resize disk partition information, the Apple Partition information is lost, and Mac OS X can no longer boot. Windows is a terrible guest.

I need some advice about the macbook pro and iPhone 5.
I took a video on my iPhone and tried to email it it said it was too big to send? So i downloaded it to my macbook pro and tried to mail it to no avail? The macbook tells me the server won't let it through other mail goes through any ideas how to resize it or what it might take to send it?

I agree with LowLister, the best option for you to share the video online is to upload it to your online storage account for example : Box, Dropbox, SkyDrive (All of them provide free storage beginning from 2GB).
You can upload the files which you want to share in this online storage and then they have sharing options in which you'll will get the link of the file to be sent and send the email. You're good to go!
Tip : You can store multiple files for backup purposes.

Songs disappearing. Need some advice.

I need some advice regarind my ITunes library. I spent a lot of time importing all my cd's. I now have approx. 14,000 songs now. First I had put them all in as mp3's, then I heard about the quality and smaller size of AAC. I think that is where some duplicates came from. But some how I've ended up with up to 6 of a lot of my songs, at least it is showing 6 copies of many of my song in my ITunes library. But when I go to delete all but one of the songs, through ITunes, sometimes it is fine and sometimes I get the ! icon. I guess even though I left one in Itunes it actually deleted all copies. I did not know I was doing this because it doesn't show the ! icon until you go back and try to select the song. This took days and days to deleted over 6,000 duplicates.
Now I'm finding some albums are missing songs and some are missing the whole albums even though they show in Itunes. I even have gone through and tried to "FIND" the songs some are really there but most are not. So how to I go about reconstructing the library. Is it best to try and find each one or just wipe (delete) my library clean and just reimport the entire library? I'm talking about reconstructing approximately 12,000 songs and I have no idea how many cd's.
I just would like to know how you guys would handle this. Thanks for your help.

Need some advice....I just bought the new retina MacBook Pro (2,199 model) and after reading about the ghosting or burn in issues that some users are experiencing I am starring to wonder if I made the right decision. I am still waiting for my laptop to come in so I can still cancel my order. I'm seriously considering opting for the non-retina MacBook Pro instead. This will be my first Mac and I will mainly be using it to browse the web and do photo editing (I'm an amateur photographer) I know the non-retina doesn't not come with SSD and wondering how much of difference that makes. Any advice, suggestions will be welcomed
That's incorrect:
Order online and for a fee you can have an SSD.

Is an anti-virus needed for a new macbook pro?

Is an anti-virus needed for a new macbook pro with retina display?

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

Business Delegate pattern - need some advice

Hi. First let me apologize for the long post. I could see no other way. I�m building a system that quite large and I need some advice. The system is a type of transaction system, let�s suppose a shopping cart. I�m using struts taglibs and tiles for presentation, struts proper for controller, and POJOs for business logic. Also I�m using OJB for my data tier.
Now I�ve been reading Pro Jakarta Struts (Apress), which BTW is a recommended read to anyone with novice experience in struts and related technologies. I�ve assimilated most of the techniques and patterns described in the book, and most of them make sense to me. However, I�ve hit a snag while reading the Business Delegate and Service Locator patterns.
The way I had though of building my application before reading the book, was to have a wrapper class, such as the following:
public class ShoppingCart {
private IAuthenticationService authenticationService;
private ITransactionService transactionService;
public ShoppingCart() {
     authenticationService = new DBAuthenticationService();
     authenticationService = new DBTransactionService();
public login(String username, String password) {
     String sessionToken = authenticationService.logon(username, password);
     return sessionToken;
private boolean isValidUser(sessionToken) {
     bolean validUser = authenticationService.isValidUser(sessionToken);
     return validUser;
public performTransaction(sessionToken, TransactionVO) {
     if (!isValidUser(sessionToken) {
          throw new AuthenticationException();
     transcationService.performTransaction(TransactionVO);
public editPreferences(sessionToken, PreferencesVO) {
     if (!isValidUser(sessionToken) {
          throw new AuthenticationException();
     authenticationService.performTransaction(PreferencesVO);
}My idea was that my wrapper class would isolate all the business logic and could perform login service in case my application was ever to be used with other presentation layer than struts (standalone client, web services). However I believe that this overlaps the Business Delegate pattern and maybe even totally implements it. The way I understand the code I�m reading in the book, they suggest having a BD for each major service such as AuthenticationServiceBD, TransactionServiceBD, etc� However this would break my single point of entry for authenticating users. I really need some advice on my design and how it fits with the BD and SL patterns (or others). I would also like to know what you think/recommend of my authentication strategy.
thanks in advance

Thanks for your reply. This however, I understood. My concern is regarding my application in regards to business delegate pattern. You see I have this class (simplified for clarity):
public class ShoppingCart {
   private ILoginService ls = new DBLoginService();
   private ITransactionService ts = new DBTransService();
   // and so on for all services I offer.
   // then I mirror all the calls of my private interfaces
   // and pass them through internally
   public String sessionToken login(String username, String password) {
        ls.login(username, password);
   public boolean addToCart(sessionToken, itemNo) {
        // check session
        ts.addToCart(sessionToken, itemNo);
   // and so on
}Multiple questions for this one:
1) Am I not already implementing the Business Delegate pattern with my ShoppingCart class since all interfaces are private and all calls are mirrored from the wrapper class (ShoppingCart) to the private interfaces? All services are implemented as POJOs and I am not using JNDI at the present so I don't use the ServiceLocator pattern.
2) I store a reference to the wrapper class (ShoppingCart) in the ServletContext so I can grab it from my Action classes. What do you think of this approach?
3) How many BDs should an application contain. In my case I use just one. What is the advantage of using more?
4) I create my own session tokens in case I ever want to use to business code in a non-web applications where sessions are not available readily. This brings about the problem that I can't pass the interfaces directly to the Action classes because the login session needs to be checked before any calls to services. So all methods include a sessionToken parameter which I use to check the session. This way, if I want to expose some of the services through web services, I can still use a login. What do you think of this approach.
5) Any other remarks are very welcome...
I really need help with this from an experienced programmer. Most things I can handle on my own but with this type of design issue, books just don't cut it. I need experience. I would really apreciate some feedback.

ps: I would give all my Duke dollars for this (I only have 30), but I'm not sure how. If you want them I can create a dummy question and give them to you.

When I burn a disc from a playlist in iTunes, the track names and artist info does not display on the disc when friends view/listen to it. This probably is an easy fix, but I need some advice.

When I burn a disc from a playlist in iTunes on my MacBook, the track names and artist info does not display on the disc when friends view/listen to it. This probably is an easy fix, but I need some advice.

No, this standard has been implemented for several decades.
How iTunes remembers audio CDs - http://support.apple.com/kb/TA27785
It is just conceivable you burned a CD that exactly matched one already in the Gracenote database. Gracenote uses track count and duration to decide what CD it is you have in a computer. If you have one that matches that it will label it. You could conceivably even have one that matches it that is not the correct one.
This script will only work on Macs:

Upgrading from Snow Leopard to Lion or Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mavericks
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.

What cable/adapter do I need to connect my MacBook Pro to a Sharp Aquos TV?

What cable/adapter do I need to connect my MacBook Pro to a Sharp Aquos TV?
I want to watch videos on youtube or read articles on my laptop, and I want a cable/adapter that will hook up the Macbook to the TV and display the webpage that is on the laptop.

Of course it doesn't. But you can buy an adaptor from HDMI to the Mini-DisplayPort port on the computer.

HT5299 which cables do I need to connect my macbook pro 2013 to an hd tv?

which cables do I need to connect my macbook pro 2013 to an hd tv? The port's on the side have changed from my previous Mac. Thank you.

If you have a retina MBP use a HDMI to HDMI cable.
If you have a non retina MBP, use a minidisplay port to HDMI cable. Insert the minidisplay end in the Thunderbolt port.
Ciao.

What cable do i need to connect my macbook pro to the hdmi input on my tv?.

what cable do i need to connect my macbook pro to the hdmi input on my tv?.

hi Sam
It's actally an HDMI adapter that Apple sells.
You hook the small adapter up to your MBP and then HDMI cable to your TV. Please note adapter is for HDMI compliant for HDMI rev 1.3 and above:
My TV, which has DVI port also, besides HDMI gets its best resolution by DVI of which also sell at Apple store for the MBP.
Bottom line is check w/ your TV manufacture to be sure your flat screen supports 1920 X 1200.
Let 'er rip and...
cheers
