Check PIN using keypad and some smartcardio-classes are different?

Hello,
I started testing with javacards a few weeks ago. I started using the OCF in my application, but now I want to use the Java6-classes, but I am new to this.
My first problem: there are different classes in the java docs online then in my java6. E.g. I do not have a class called CardTerminals. factory.terminals() returns a List<CardTerminal>.
Do I use the wrong Environment?
My second question: how can I ask for my cards PIN? For entering it I want to use my card-readers (Kobil Kaan Advanced) pinpad.
Thank you in advance for any help,
Susanne

Oh...ok, my misunderstanding. But....is this way secure? Perhaps "prompt" was the wrong expression. I want, that the user has to enter his PIN with the build-in pinpad. I am not sure, but isn'T it that way, that the entered pin is not send back to my application? Because then the pinpad would be senseless and i could use the pcs keyboard.
So I thought there is an (apdu)command, that "says" to the cardreader: let the user enter his PIN (my cardreader then makes a "beep" and you can enter the pin via pinpad). After that the card sends back "ok" (90 00 or so). So the application can continue.
The "prompt" I thought of, should never get the real numbers from the pinpad, but only displays * or so when a key is pressed on keypad.

When to use interface and when Abstract Class?

In a recent interview I was asked "When to use interface and when Abstract Class?" Explain with an example.
Also in what situations a class should be made final(real time example)

Interface is a pure contract with no implementation. Typically used to define a communication contract between two different sub-systems. Example EJB home interface. This also allows the design to change as long as the contract is met.
Abstract class is when there exists a lot of common functionality already known and can be coded. However, a few unknowns exists (typically about data) for which abstract methods need to be defined and implemented by the sub class.
Example: Consider a workflow engine. A great example for abstract class. The workflow process has lot of common code that is independent of the workflow type (vendor flow, contract flow, payment flow etc). However, certain decisions on the route to take will depend on value of data being submitted. So the base class will define a abstract Data getData() method and proceed assuming data will come. The implementing subclass will provide the actual logic for getting the data.
Also see the "Template" design pattern.
Note: To some extent the common code design drives the behavior of the abstract methods. So if the design changes then so "might" the behavior expected from the abstract methods.

My keyboard on macbook pro (laptop) is acting weird. One key is not responding at all. Have verified using Keyboard viewer and some other keys are printing the unresponsive character at random.

my keyboard on macbook pro (laptop) is acting weird. One key is not responding at all. Have verified using Keyboard viewer and some other keys are printing the unresponsive character at random. "z" is the unresponsive character.
Is it a damaged keyboard ?
The laptop is just 2 months old, will Apple replace it with a new one if its indeed a damaged keyboard or just repair, I use it for official purposes so being without a laptop is not much of an option.

No one here works for Apple, so we don't know what Apple might or might not do. If it's a genuine defect, they will of course repair it under warranty. It is not their responsibility if it effects your ability to work or not, so that's on you.
If, however, they determine that the key is problematic as a result of your misuse of the laptop, then everything is on you. And trust me, if they find a glob of dried up beer or coffee there, they will charge you.
Your only choice is to take it in for repair.

Just installed mountain Lion. Viewing a pdf sent to me using preview and some colors are appearing BLACK, however when I view the same PDF in Acrobat they are perfect and what they are suppose to be. WHY would PREVIEW showing a different color?

Just installed mountain Lion. Viewing a pdf sent to me using preview and some colors are appearing BLACK, however when I view the same PDF in Acrobat they are perfect and what they are suppose to be. WHY would PREVIEW showing a different color?

Here's what I've found on the issue:
Pantone color definitions have changed (coinciding with CS6) — they are now "Pantone+" (I think that's what they're called). The "+" apparently means they're now LAB colors. Lab colors are not properly displayed in Preview (or in Finder previews) — they display as black (as far as I can tell, in all circumstances). I'm sure it's a tad more complicated than that, but that's the gist.
Now the bad news — nobody seems to know anything about a fix or workaround (unless you convert your PDFs to process — this might be a fix for sending to clients). It causes issues for me in AI files — being able to view them in the finder (with previews) is a HUGE time saver for my workflow... when they're all black, not so much.
In my chat with a director of product dev at Adobe, they placed the responsibility to fix on Apple (assuming Apple wants to support Pantone color definitions in their OS).

My iCloud email address and my apple ID are different. I would like to change my iCloud to be the same as my apple ID. However I don't know my iCloud password and don't use the email address it belongs to. When I try to change the password, apple brings me to a page to reset my apple ID password (which I know and don't want to change). I have even tried to delete my iCloud account completely to start again but am not allowed without the iCloud password (which I don't have) there doesn't seem to be a place to change the email address of iCloud. What can I do?

This is the answer that I had expected, so in this case you could only change your gmail.com address to another providers email addres e.g. outlook.com, yahoo.com, etc., but you won't be able to change the gmail.com address to a icloud.com email address. Apple just won't let you do that.
Your iCloud account with @icloud.com email address and you Apple ID with gmail.com address are already connected and as I said before, Apple just let you merge this two IDs together.

I have a macbook pro with OSX Mavericks 10.9.5 and some keys that are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it

I have a macbook pro with OSX Mavericks 10.9.5 and some keys randomly are not working. Specifically, the enter/return button, the "p", "0", ";", and all the function keys. What's really weird is that happens randomly. I've never spilled anything on it, and I can't for the life of me figure out how to fix this. Can anyone help? of course this happened after my warranty expired.

**update**
I don't know if this will help someone but I am posting this for that purpose. In the past when I first had this problem, I'd read a post somewhere (sorry, long ago, don't have the link) where an individual was having the same problem and they stated that when the MBP got heated, that's when the keys would stop working, and they went into the MBP and jiggle some stuff around (a specific wire, I'm not electronically inclined so I know NOT of what they spake!). Well I didn't want to do that but it always stuck in the back of my mind. I had given up, really, and was planning to take my MBP to the apple store. But by chance one night I left my MBP on the floor where it's cool, and when I turned it on, the problem went - poof! It seems there was some validity to the post that spoke about heat, because my problems started when I would stream foreign dramas on my MBP for hours at night, and I would hear the fan going off all the time, and in the mornings, my "p", "enter", "0", ";", and all the function keys would stop working.
So, maybe try keeping the MBP in a cool place when it's off. Since I've started doing this overnight every night (keeping it on the cool floor, out of reach of any big feet), I have not had a single problem with my keyboard.
Hopefully this might help someone.

I use gmail and some emails I get do not show the graphic or picture only a small graphic icon.

I use gmail for my email. Some of the emails I receive do not show the graphic or photo. I can see the graphic/photo in Internet Explorer and when I hit reply in Firefox. This started happening about 5 months ago. I used to be able to see the emails with no problem... I have checked all options and do have display images turned on. This happens with every email from a yahoo group and some other emails as well. I have the latest version of Firefox. I tried uninstallng and reinstalling firefox... no change.
== This happened ==
Every time Firefox opened
== about 5 momths ago

Check the image exceptions: Tools > Options > Content: Load Images: Exceptions - See [[Options window - Content panel]]
A way to see which images are blocked is to click the favicon (''Site Identification'' icon) on the left side of the location bar and click the "More Information" button.
This will open the Security tab of the ''Page Info'' window (also accessible via Tools > Page Info).
Go to the ''Media'' tab of that Page Info window.
Select the first image and scroll down though the list with the Down arrow.
If an image is grayed and there is a check-mark in the box ''Block Images from...'' then remove that mark to unblock the images from that domain.

My account lost information about my order and subscription. As a result I can't use Lightroom and Photoshop as they are in the state of the expired demo.

Hi
I paid my annual subscription on the 26th of November last year. I've installed both Lightroom and Photoshop and started using them quite successfully.
Then I installed the same products on my home Mac and migrated all my Apperture libs to it. Everything went smoothly.
However one day I got a message that I can't develop photos in Lightroom due to my account problems. I logged in into my adobe id to check what's wrong and realized that my account was on free creative cloud.
I tried to check my other appleIds - all were empty. I found a link at the Adobe FAQ how to check orders but the page didn't find my order number I took from the Adobe order confirmation email.
Does anybody know how to make it all working again? How to link again my paid order to my AdobeId?
Alexey

Hello - Is the issue still pending

I'm using gmail and lately new emails are showing up in my drafts box. How do I keep that from happening?

I'm using gmail on the latest version of OS X. New emails keep showing up in my drafts mailbox along with my inbox. How do I correct this? Thanks for your help.

If it's incoming messages that you don't create, then check in Mail to make sure no rules are created to move messages to the draft folder.
Unchecking storing drafts messages on the server should tell you if the problem is originating from the computer. If it stops on the computer and still happens in the IMAP draft folder under the gmail folder (you can check the website also), then it will be a setting or filter action at the gmail website.
If messages still arrive in the draft folder (which will now be a local folder), then you will know that the computer is causing the problem. Then we can figure what's causing the problem.

How to change the homepage for a new tab when the home page of the initial tab and subsesequently opened tab are different?

When iam using firefox i selected google as my home page. But while opening another tab in the same window(ctrl+T), I am getting babylon search as home page for it. How can i get rid of this problem?

Any search toolbar and changes to search engines can take place by downloading and installing software; usually "free" software from the internet. Babylon can be downloaded and installed by itself or as a "ride-along" when installing/updating some software from the internet. Always look for an opportunity during the installation to un-check boxes that will install "ride-along" items that you do not want. Firefox installation does not include such "ride-along" items.
