Questions about DAO

Hi,
we have some questions about DAO, Someone knows the answers?
In versión 10g, one could create DAOs (Data Access Objects) from DB and then they could use them for extract and store data.
In BPM 11g, how one could store information in the DB? How can they integrate them?
Thanks in advance
Antonio

In 11g Database Adapters are used for direct access to the database. You add a DB adapter reference to your composite then this gets exposed as a service that can be invoked from the BPMN/BPEL process.
Some documentation can be found here:

Questions about DAO pattern

Hi,
I am a junior programmer and I am trying to understand somewhat more about best practices and design patterns.
I am looking for more information regarding the DAO pattern, not the easy examples you find everywhere on the internet, but actual implementations of real world examples.
Questions:
1) Does a DAO always map with a single table in the database?
2) Does a DAO contain any validation logic or is all validation logic contained in the Business Object?
3) In a database I have 2 tables: Person and Address. As far as I understand the DAO pattern, I now create a PersonDAO and an AddressDAO who will perform the CRUD operations for the Person and Address objects. PersonDAO only has access to the Person table and AddressDAO only has access to the Address table. This seems correct to me, but what if I must be able to look up all persons who live in the same city? What if I also want to look up persons via their telephone numbers? I could add a findPersonByCity and findPersonByTelephoneNumber method to the PersonDAO, but that would result in the PersonDAO also accessing the Address table in the database (even though there already is an AddressDAO). Is that permitted? And why?
I hope someone can help me out.
Thanks for your time!
Jeroen

That is exactly what I am trying to do. I am writing it all myself to get a better understanding of it.
Please bear with me, because there are some things I dont understand in your previous answer.
1) Each BO validates his corresponding DTO and exposes operations to persist that DTO. Each DTO will be persisted in the database via his corresponding DAO. So this would be:
- in PersonBO
public void save(PersonDTO personDTO) {
this.validate(personDTO); // does not validate the nested address DTOs
this.personDAO.save(personDTO); // does not save the nested address DTOs
- in AddressBO
public void save(AddressDTO addressDTO) {
this.validate(addressDTO);
this.addressDAO.save(addressDTO);
Am I viewing it from the right side now?
2) Imagine a form designed to insert a new person in the database, it contains all fields for the Person DTO and 2 Address DTOs.
How would I do this using my Business Objects?
This is how I see it:
// fill the DTOs
daoManager.beginTransaction();
try {
personBO.setDao(daoManager.getDao(PersonDAO.class));
personBO.save(personDTO); // save 1
addressBO.setDao(daoManager.getDao(AddressDAO.class));
addressBO.save(personDTO.getAddress(1)); // save 2
addressBO.save(personDTO.getAddress(2)); // save 3
daoManager.commit();
catch(Exception e) {
daoManager.rollBack();
If I insert the transaction management inside the DAOs, I can never rollback save 1 when save 2 or save 3 fail.
It can be that I am viewing it all wrong, please correct me if that is the case.
Thanks!
Jeroen

Question about DAO pattern

Greetings.
If I'm using EJB's in my application when does DAO fits in?? I mean, it is DAO an alternative to EJB's or a complement ??
Thanks in advance.

DAO fits in if you are using entity beans using bean managed persistence. In this case, the DAO brokers the database calls during the EJB's lifecycle. The other instance when you would use DAO would be if you forgo entity beans altogether. In this model, stateful or stateless session beans would use DAO's to broker the database calls directly, outside of the normal entity bean lifecycle. The DAO pattern can also be used with POJO's (plain 'ole Java objects).
The only instance where DAO would not apply is in the case of a container managed entity bean. In this case, there is no need to write a DAO, as the container will persist the bean for you.

About DAO

I have read something about DAO with the help of some sites. But I didnt clearly understand "In what scenario, we use them"?? If we dnt use this DAO concept, what happens?? Im not asking "HOW do we implement DAO", but my question is "WHY do we use DAO "..I got an answer for "how", but I didnt clearly understand for "why"..Please tell me with some clear explanations instead of single line answers.

Well, there are really two high level patterns here. Assuming you are going from something like a service based architecture, you will either go service -> dao -> domain object. Or you will go service -> domain object -> dao. I think the first one is a bit easier to understand.
If you opt for the first option, the service will create the dao (which should be stateless, e.g., no instance variables that are not static and final). You then call a method on the dao (say 'selectFoo()') passing in a primary key and having Foo returned. The other common use would be to create a new instance of Foo, in which case the service would call something like insertFoo() which would return your new object.
The second option involves just a bit more indirection. On Foo, you would place methods such as update()/save(), delete(), etc. You still need a way to get an instance of Foo. So, you can either create an AbstractFactory or put static methods on Foo such as getInstance() and newInstance(). Foo will delegate its calls to a dao for the actual database operations.
Now, in the first design, you have separated as much as possible the domain logic from the persistence logic. (You normally have to make a compromise such as putting the primary key of Foo in the domain object, since you need to let the dao know how to update or delete the record). The downside is that you now have to provide a number of getters and setters (or additional constructors) for Foo for the dao to use.
In the second design, you have mingled the domain and persistence logic a lot more. However, since the methods are all defined on Foo, you can get away with far fewer getters/setters/constructors than in the first design. In fact, with the second design, you really do not need a DAO at all. You can leave the persistence methods completely within Foo.
One advantage the first design has over the second design (at least superficially) is that you can have multiple dao's all creating a Foo from different sources (say, an Oracle database, a MySql database, a XML file, etc.) In my experience, most objects are persisted in a single way. You can still opt for the second design and have multiple persistence strategies. In this case, you would have a series of helper classes within Foo (nested, inner classes).
The choice is up to you. Some people really want to move the persistence logic out of the model and make it a separate tier. That pushes you, a bit, torwards design 1. Some people really want to keep encapsulation, and this pushes you a bit towards design 2. There is no right or wrong answer, and you can mix both styles in your application.
For the dao's themselves, you also have a number of options. You can keep them public objects in their own packages and create a separate persistence tier. Or you can keep the dao's in the same package, make them non-public where possible, and use them simply as helper objects for the dao. Finally, you can eliminate the dao altogether via anonymous/inner classes.
In terms of how the dao is designed on a class level, it depends on whether you want to use vanilla jdbc, an orm such as hibernate or jpa, or a hybrid such as iBatis. Generally, all of them will either need the information needed to establish a connection. Generally, they will need to clean up resources such as statements, result sets and connections.
You will likely want to use a connection pool, such as Jakarta Commons DBCP. This improves efficiency and moves the connection logic out of java and into configuration. If you opt for a container (whether J2EE or Spring or something similar), the whole picture gets a lot easier. These will generally clean up resources, perform transactional logic and obtain connections via either configuration or annotations. http://static.springsource.org/spring/docs/2.0.x/reference/jdbc.html.
So, in a roundabout way of answering your question, there is no "harm" in not using dao's. Generally, a database will outlive the applicaation that created the data. So, separating persistence from domain logic has additional value there. You also gain the benefit of concentrating on SQL in one set of classes and remaining in the java world for your other objects. It also can help somewhat in reducing the size of your domain model classes.
No right or wrong, it's just a convention to use them.

My HP, purchased in June 2012, died on Saturday. I was working in recently installed Photoshop, walked away from my computer to answer the phone and when I came back the screen was blank. When I turned it on, I got a Windows Error Recovery message. The computer was locked and wouldn't let me move the arrow keys up or down and hitting f8 didn't do anything.
I'm not happy with HP. Any suggestions?

Questions about using the Voice Memos app

I'm currently an Android user, but will be getting an iPhone 6 soon. My most used app is the voice memos app on my Android phone. I have a couple questions about the iPhone's built-in voice memos app.
-Am I able to transfer my voice memos from my Android phone to my iPhone, so my recordings from my Android app will show up in the iPhone's voice memos app?
-When exporting voice memos from the iPhone to computer, are recordings in MP3 format? If not, what format are they in?
-In your opinion, how is the recording quality of the voice memos app?

You cannot import your Android voice memos to your iPhone's voice memo app. You might be able to play the Android memos and have the iPhone pick up the audio and record it.
Here is the writeup about sending voice memos from the iPhone to your computer (from the iPhone User Guide):
App quality is excellent.

Re: Question about the Satellite P300-18Z

Hello everyone,
I have a couple of questions about the Satellite P300-18Z.
What "video out" does this laptop have? (DVI, s-video or d-sub)
Can I link the laptop up to a LCD-TV and watch movies on a resolution of 1080p? (full-HD)
What is the warranty on this laptop?

Hello
According the notebook specification Satellite P300-18Z has follow interfaces:
DVI - No DVI port available
HDMI - HDMI-out (HDMI out port available)
Headphone Jack - External Headphone Jack (Stereo) available
.link - iLink (Firewire) port available
Line in Jack - No Line in Jack port available
Line out Jack - No Line Out Jack available
Microphone Jack - External Micrphone Jack
TV-out - port available (S-Video port)
VGA - VGA (External monitor port RGB port)
Also you can connect it to your LCD TV using HDMI cable.
Warranty is country specific and clarifies this with your local dealer but I know that all Toshiba products have 1 year standard warranty and also 1 year international warranty. you can of course expand it.

Some questions about Muse

First of all, I would like to say that I am very impressed with how well Muse works and how easy it was to create a website that satisfies me. Before I started a daily updated website I thought I would encounter many problems I will not be able to solve. I have only had a few minor issues which I would like to share with you.
The most problems I have with a horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html). Marking and copying of a text is possible only on the last (top) layer of a document. The same situation is with widgets or anything connected with rollover state - it does not work. In the above example it would be perfect to use a composition/tooltip widget on the first page. Unfortunately, you cannot even move the cursor into it.
It would be helpful to have an option of rolling a mouse to an anchor (like in here http://www.play.pl/super-smartfony/lg-nexus-5.html and here http://www.thepetedesign.com/demos/onepage_scroll_demo.html). I mean any action of a mouse wheel would make a move to another anchor/screen. It would make navigation of my site very easy.
Is it possible to create a widget with a function next anchor/previous anchor? Currently, in the menu every button must be connected to a different anchor for the menu to be functional.
A question about Adobe Muse. Is it possible to create panels in different columns? It would make it easier to go through all the sophisticated program functions.
The hits from Facebook have sometimes very long links, eg.
(http://www.leftlane.pl/sty14/mclaren-p1-nowy-krol-nurburgring.html?fb_action_ids=143235557 3667782&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582). If such a link is activated, the anchors in the menu do not work on any page. I mean the backlight of an active state, which helps the user to find out where on page they currently are. The problem also occurs when in the name of a html file polish fonts exist. And sometimes the dots does not work without any reason, mostly in the main page, sometimes in the cooperation page either (http://www.leftlane.pl/wspolpraca/). In the first case (on main page), I do not know why. I have checked if they did not drop into a state button by accident, moved them among the layers, numbered them from scratch and it did not help. In the cooperation page, the first anchor does not work if it is in Y axle set at 0. If I move it right direction- everything is ok.
The text frame with background fill does not change text color in overlay state (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html). I mean a source button at the beginning of every text. I would like a dark text and a light layer in a rollover, but the text after export and moving cursor into it does not change color for some reason.
I was not sure whether to keep everything (whole website) in one Muse file (but I may be mistaken?). I have decided to divide it into months. Everyone is in a different Muse file. If something goes wrong, I will not have any trouble with an upload of a whole site, which is going to get bigger and bigger.
The problem is that every file has two master pages. Everything works well up to the moment when I realize how many times I have to make changes in upper menu when I need to add something there. I have already 5 files, every with 2 masters. Is there any way to solve this problem? Maybe something to do with Business Catalyst, where I could connect a menu to every subpage independently, deleting it from Muse file? Doing so I would be able to edit it everywhere from one place. It would make my work much easier, but I have no idea jendak how to do it.
The comments Disqus do not load, especially at horizontal layouts (http://www.leftlane.pl/sty14/2014-infiniti-q50-eau-rouge-concept.html). I have exchanged some mails and screenshots with Disqus help. I have sent them a screenshot where the comments are not loaded, because they almost never load. They have replied that it works at their place even with attached screenshot. I have a hard time to discuss it, because it does not work with me and with my friends either. Maybe you could fix it? I would not like to end up with awful facebook comments ;). The problem is with Firefox on PC and Mac. Chrome, Safari and Opera work ok.
YouTube movie level layouts do not work well with IE11 and Safari 7 (http://www.leftlane.pl/sty14/wypadki-drogowe--004.html). The background should roll left, but in the above mentioned browsers it jumps up. Moreover the scrolling with menu dots is not fluent on Firefox, but I guess it is due to Firefox issues? The same layout but in vertical version rolls fluently in Firefox (http://www.leftlane.pl/sty14/polskie-wypadki--005.html).
Now, viewing the website on new smartphones and tablets. I know it is not a mobile/tablet layout, but I tried to make it possible to be used on mobile hardware with HD (1280) display. I mean most of all horizontal layouts (http://www.leftlane.pl/sty14/2015-hyundai-genesis.html), where If we want to roll left, we need to roll down. Is there a way to make it possible to move the finger the direction in which the layout goes?
On Android phones (Nexus 4, Android 4.4.2, Chrome 32) the fade away background effect does not work, although I have spent a lot of time over it (http://www.leftlane.pl/lut14/koniec-produkcji-elektrycznego-renault-fluence-ze!.html). It is ok on PC, but on the phone it does not look good. A whole picture moves from a lower layer instead of an edge which spoils everything.
This layout does not look good on Android (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html#a07). The background does not fill the whole width of a page. There are also problems with a photo gallery, where full screen pictures should fill more of a screen.
Is it possible to make an option of scroll effects/motions for a fullscreen slideshow widget thumbnails (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06)? It would help me with designing layouts. Currently, it can go from a bottom of a page at x1 speed or emerge (like in this layout) by changing opacity. Something more will be needed, I suppose.
Sometimes the pictures from gallery (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06 download very slowly. The website is hosted at Business Catalyst. I cannot state when exactly it happens, most of the time it works ok.
I really like layouts like this (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a03). On the top is a description and a main text, and the picture is a filled object with a hold set at the bottom edge. That is why there is a nice effect of a filling a whole screen- nevertheless the resolution that is set. It works perfect on PC, but on Android the picture goes beyond the screen. You can do something about it?
In horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html) holding of a filling object does not work. Everything is always held to upper edge of a screen regardless the settings. Possibility of holding the picture to the bottom edge or center would make my work much easier.
According to UE regulations we have to inform about the cookies. I do not know how to do it in Muse. I mean, when the message shows up one time and is accepted, there would be no need to show it again and again during another visit on the website. Is there any way to do it? Is there any widget for it maybe?
The YouTube widget sometimes changes size just like that. It is so when the miniature of the movie does not load, and the widget is set to stroke (in our case 4 pixels, rounded to 1 pixel). As I remember ( in case of a load error) it extends for 8 pixels wide.
Last but not least - we use the cheapest hosting plan in Business Catalyst. The monthly bandwidth is enough, although we have a lot of pictures and we worried about it at first. Yet we are running out of the disk storage very quickly. We have used more than a half of a 1 GB after a month. We do not want to change BC for a different one, because we like the way it is connected with Muse. But we do not want to buy the most expensive package - but only this one has more disk space. We do not need any other of these functions and it would devastate our budget. Do we have any other option?
I’m using Adobe Muse 7.2 on OS X 10.9.1.
and I'm sending Muse file to <[email protected]>

Unfortunatley, there is no way to get a code view in Muse. I know quite a few people requested it in the previous forum, but not really sure where that ended up. Also, you may not want to bring the html into DW unless you only have 1 or 2 small changes 2 make. Two reasons. First, it isnt backwards compatible, so if you are planning on updating that site in Muse, you will need to make those changes in DW everytime you update. Second, by all accounts the HTML that Muse puts out is not pretty or easy to work with. Unlike you, I am code averse, but there was a lenghty discussion on the previous forum on this topic. I know they were striving to make it better with every release, just not sure where it is at this point.
Dont think I am reading that second question right, but there was a ton of info on that old site. You may want to take a look there, people posted a ton of great unique solutions, so it worth a look.
Here is the link to the old forums- http://support.muse.adobe.com/muse

HT201303 hi just got my new apple ipod touch i need to update my security information other wise it wont let me download apps it says to enter three questions about myself and i get to the third question and it wont let me enter the third question

hi just got my new apple ipod touch and to download apps it wants to add questions about myself for more sercurity information. i get up to question 3 and it wont let me select a question but it will let me write an answer so i just pressed done and then it says i cant carry on because ive mised out information when it wont let me do a question!

Welcome to the Apple community.
You might try to see if you can change your security questions. Start here, change your country if necessary and go to manage your account > Password and Security.
I'm able to do this, others say they need to input answers to their current security questions in order to make changes, I'm inclined to think its worth a try, you don't have anything to lose.
If that doesn't help you might try contacting Apple through Express Lane (select your country, navigate to iCloud help and enter the serial number of one of your devices)

Just installed iOS6, questions about "iMessage" and other things...

I've been a satisfied iOS4 user since I bought my iPhone4, but I was forced to install iOS6 tonight in order to download a "free" app. I found a few new icons on the screen along with about 200 percent more "Settings" I'd like to ask some questions about. I'm sure a few of these could be answered by doing a frantic and thorough search through weeks of posts but I'm a little short on time right now.
First, what exactly is iMessage? Looking at the page for it, I can't see any difference between it and regular text messages. The info page says its to avoid charges, but between my data plan and not being charged for text I don't see where theres any other benefit. The one person I text with the most recently asked me why I had not installed iMessage yet, and didn't have an answer when I asked him why I should. I guess he just wanted to see text replies in blue instead of green.
In a related bit, flipping through Settings>Messages>Send & Receive I find a "2 addresses" section, with my phone number in there as well as my email under "You can be reached by iMessage at:" and "Start new conversations from:". What good does it do iMessages to have my email address? Does the Mail app handle text as well as email addresses? That seems to be the only explanation, and also very odd to think I'd be trying to text through my Mail app.
Second, looking through the Settings>Mail I see now that I have an icloud email address as well as the mac.com address I've been desperately hanging on to for the past 10 years, and the me.com address they've been trying to force me into since those came out. (I was happy to see I could delete the me.com address from the phone. I wish I could delete it from the universe.)
I wasn't even aware there was a such thing as icloud.com addresses. When did this happen? What is it used for?
Third, under that icloud Setting I see a long list of apps with buttons labeled "Off" under it. What are those for? Under the Mac.com settings I see switches for "Mail" and "Notes", with Mail on and Notes off. The Notes app (which I haven't used since my old iPhone 3) still opens, regardless of this setting.
Fourth, I now have an item called "Facetime" under my Settings. It is off, but underneath it says "Your phone number and/or email address will be shared with people you call". I understand caller ID normally sends caller number info to the receiver, but why would someone need my email address if I call them?
Fifth, I now have a "Music" setting, at the bottom of which I see a "Home Sharing" item, which when clicked brings up my AppleID and asks me if I want to Sign Out or Cancel. What is Home Sharing? Its also at the bottom of the "Video" settings.
Sixth, now I have Twitter and Facebook settings? For what? I don't have accounts with either of those companies. So why have settings, especially since it asks me to create accounts and download apps for those companies right in the Settings?
Seventh, there is a camera icon on the unlock screen. Touching it causes the screen to bounce up about a quarter inch, almost but not quite revealing something behind it. I should probably just quit asking about this stuff already, but I'll take the bait - what is this now?
Finally, what is the Notification Center used for?
If I got a text under iOS4, it would put an alert on the Unlock screen. Scrolling through this huge list of things under the Notification settings I'm really blown away by all the apps set up to yell at me. I can see having an alert for a text message but Game Center? What the heck is that, and why is it set up to hit me with a "Badge App Icon" (whatever that is) when I get alerts from "Everyone". Similarly, the phone is set to alert me to something called a "Photostream Alert"? What is this? Why is there a Phone section for the Notification Center? So they can put a Notice on my screen to tell me the phone is ringing? Holy cow! The phone is set to send me alerts from the "Weather Widget". So if I miss the fact its raining there will be a message on my screen to let me know? Whats next - a buzzer to tell me I'm listening to music?
There's a lot more, like what would I need Passbook for when I have the actual movie tickets, gate boarding passes, coupons, etc in my hands, but we'll leave that for another time. Many thanks to all who can offer some answers to my questions above.

Hey Taantumus!
Here is an article that will provide some guidance on this question:

Questions about using Bitlocker without TPM

We currently use Bitlocker to encrypt our Windows 7 computers with TPM. Now we are looking at encrypting some Windows 7 computers without a TPM. I see how to change the group policy setting to allow Bitlocker without a TPM. I have looked at a lot of other
threads and I have a few questions about how the Bitlocker without TPM works.
1) I see a USB drive containing a key is required for Bitlocker configurations without a TPM, say the end user loses this USB drive, what are the recovery options for their computer?
This article seems to indicate that without the USB drive connected, you are unable to even access recovery options http://blogs.technet.com/b/hugofe/archive/2010/10/29/bitlocker-without-tpm.aspx
We have recovery backed up to AD when Bitlocker is enabled, but how could we do this recovery on a computer on computer where it's USB is lost? Would we have to remove the HD itself and attach it to another computer to access?
2) After enabling Bitlocker on a computer without a TPM and using the USB Drive for the key, is there a way to also add a PIN or password protection at bootup?

Hi,
Sorry for my dilatory reply,
Configuring a startup key is another method to enable a higher level of security with the TPM. The startup key is a key stored on a USB flash drive, and the USB flash drive must be inserted every time the computer starts. The startup key is used to provide
another factor of authentication in conjunction with TPM authentication. To use a USB flash drive as a startup key, the USB flash drive must be formatted by using the NTFS, FAT, or FAT32 file system.
You must have a startup key to use BitLocker on a non-TPM computer.
From: http://technet.microsoft.com/de-de/library/ee449438(v=ws.10).aspx#BKMK_Key
For more Q&A about BitLocker, you can refer to the link above.
hope this is helpful.

Questions about Rooting...

Hi everyone, I’ve some questions about rooting my Xperia Arc S. Hopefully I’ll get helpful answers from you.
If I root my phone, shall I get regular software official updates from Sony?
Currently Sony is rolling out the ICS update. After rooting the phone am I able to upgrade my phone to ICS?
While rooting the phone if any damage is done, can that be recoverable by installing a fresh OS or something?
Does the rooting process delete all the existing contacts, messages, apps etc?
Finally can anyone please provide a full proof guide/tutorial for rooting the Xperia Arc S?
Thanks in advance.
Solved!

Do you have an app named Super USer ?
Were you on 4.0.4 and then rooted your mobile using this method ?
If yes then your mobile is not rooted for sure
See how to root 4.0.4 here

A lot of questions about my MacBook Air

I am really new to re-using Apple computers.The last time I used an Apple computer was back in 1987 when the school and my family had Apple IIGS computers. I have been using PC's which reqiure Microsoft. I a lot of have questions (10 questions) about my MacBook Air and I hope you good people can and will help me.
Product: MacBook Air
Operating System: Mac OS X Version 10.7.4
1) I Downloaded MacKeeper because I was fooled. I had a bad feeling just before I Downloaded it and I should have listened to my heart. However, I didn't buy it or fully Install it. It was like a test run and then they wanted me to pay almost $100 for it. Thankfully, I didn't because I read it is Malware. I spoke with an Apple Tech at Apple Care and he helped me get rid of it (or so we think). I don't see it anymore on my computer. I read it can slow down your computer. How can you tell if it's really off of the computer?
2) When I open "Finder" and I see that there are people Sharing my computer with me. I went into AirDrop and it reads, "Other people can see your Mac as (my name) MacBook Air when their computer is nearby." I bought a HotSpot and while it's turned on and I selected it as my WI-FI connection I thought it would get rid of these people, protect what I type, me, my items, computer, etc. But it didn't.
I didn't know that I have to buy a exteral CD and/or DVD Player in order to connect to the brand new Modem and Router in one by NetGear. I am so used to PCs and the CD/DVD Players being built inside.
The people at Apple Store told me that there is an internal modem inside, but I don't know how to find it and what to do then. Should I use a Firewall?, An AntiVirus, AntiMalware, AntiSpyware, etc. Apple Care tech told me I don't need to get an AntiVirus.
3) Is there a new kind of Wireless Modem and Router that doesn't require a CD-ROM?
4) When I travel or fly and I am not close to home I was told by Best Buy and Sprint that I had to buy a mobile HotSpot to use the computer (WI-FI) safely. As I typed, I have one. But it's pretty expensive and only gives me 1 hour and 15 minutes per day to Stream. What can I do to use this computer safely Online when I am out of range from a Modem and Router? What do people do when they travel on airplanes?
5) This compter won't let me use "Raid." I think you have to have a newer version. I hard about Raid on the radio from Leo (can't recall his last name) who's a Tech expert.
6) Should I buy a ZipDrive? Apple Store Tech told me that I didn't need a ZipDrive. I just remember the episode of HBO's "Sex and The City" when Carrie looses everything because her copy crashed. Now, of course, I know that's a fictional show, but with PC's and Microsoft I have lost everything when it crashed, frooze up, etc. I know there's iClouds. I heard about Carbonite, but I have read the Pros and Cons about it. Mostly they are Cons about it. I just don't want to do anything wrong and mess up this computer.
7) Should I buy a new Printer/Copier/Scanner because mine is an HP. It's not new, but it works. I even have a CD-ROM for Macs. What about the new product called, "Neat"?
8) Is there a special product that I should buy to do Online Banking and/or other important stuff?
9) I saw and read about iWork in the Apps Store and it sounds cool. I still have alot of friends and colleagues who still use Microsoft. Is iWork good to use? Should I Download it from the Apple Apps Store or can a buy it at Apple? Is there another Word Processing Program that is great and user friendly and will work with Macs and PCs?
10) Should I Update the OS with OS X Mountian Lion Pro from the Apple Apps Store or buy it at Apple Store?
In advance, I wish to thank you in this Apple Support Communites for your help. Have a safe and happy holiday weekend!

1) Here are instructions for removing MacKeeper. Since it mostly consists of manually looking for folders and specific files, if you follow the instructions you either fail to find what you are told to find (because your AppleCare guide gave you complete instructions which you followed) or you'll find some additional files that need to be replaced.
2 & 3) I assume you are looking at the sidebar of a Finder window and seeing Shared and computers under it. Those are computers that you can potentionally share. To do so you'd need an account on their computer and a password. They are not sharing your computer.
AirDrop allows you to create an adhoc network for filesharing and it only functions when you have selected the AirDop item in the SideBar. Actually doing that merely announces to computers in the same network node that your computer is available for a file to be sent to. Even then you have to explicitly allow the file to be downloaded to your computer. Similarly you'd be able to see other computers with AirDrop selected and be able to send them a file - which they'd have to accept.
The only reason your NetGear Router comes with a CD is to install and run their 'easy' step by step configuration program. It can also be done manually with a browser. Read the manual to find the IP address you must enter to access the router's configuration menu. Apple's WiFi routers don't require a CD to install the software because the configuration software is already on your computer.
I do have my firewall turned on. AntiVirus software isn't a bad idea - I use Sophos having tested it for a review for our local User Group and I found I liked it better than ClamAVx which is what I'd been using before. Both are free.
4) I think you were scammed by Sprint and BestBuy. I use hotel, coffee shop, and restaurant WiFi spots and have for years. However, because they can be unsecured, I do not shop online or bank when I'm using them. I also use 1Password and don't reuse passwords so even if a sniffer should grab an account and password that's all it would get - one account.
5) Raid doesn't really make sense with a MacBook Air - a RAID involves 2 or more disks being used as if they were one.
6) Zip drive? No. External hard drive - yes. It isn't a question of if a computer's hard drive will malfunction, it is when. OWC has a nice selection of external drives and the Mac has a built in backup system called TimeMachine. Due to the way TimeMachine works, I've found that your TimeMachine drive should be at least twice as large - and preferably 3-4 times as large as the data you are backing up.
7) if your printer works and it has Mountain Lion drivers, why replace it?
8) Online banking is done with a browser - Use Safari or FireFox
9) If trading files with Windows users is important Mac: Office is your best bet. If not, iWork, Mac:Office, or LibreOffice are all good possibilities.
10) you can only buy Mt Lion via the App Store.

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

Hi,Jochen,
Thank you for your kindly help!
The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!
