Review: Limbo
Starring: David Strathairn, Mary Elizabeth Mastrantonio, Vanessa Martinez, Casey Siemaszko, Kris Kristofferson
Written/directed by: John Sayles
Review by: Joy Wyse, the SILVER Screen Critic
The Thesaurus says that another word for Limbo is Nothingness. In this case, it's not true. There is so much for the viewer in this marvelous film. The scenery alone is breathtaking. Set in the area surrounding Juneau, Alaska, you find yourself amazed at the endless terrain. It must have been what it was like for the pioneers when they first came to America, just colder.
The main focus, however, is on the characters. We get to know them as real people and we understand why they have chosen to live in such a remote area. Each has a reason for seeking a `new' life. We immediately feel a relationship for David Strathairn as Joe Gastineau, a fisherman who does odd-jobs rather than face another tragedy aboard a ship such as the one that killed the younger brother of Smilin' Jack, played by Kris Kristofferson. He is making a delivery to the wedding of the daughter of a prestigious Alaskan businessman. Various conversations at the wedding give us great insight into life in Juneau as it is…and as they wish to portray it to tourists.
Also working at the wedding are Donna and Noelle De Angelo. Donna, portrayed by Mary Elizabeth Mastrantonio is the lead singer for the group entertaining the guests. She has suddenly decided to break up with the bandleader during a song. When she walks offstage, she coerces Joe into taking her into town to pick up her belongings.
Noelle, wonderfully played by Vanessa Martinez, is working there as a waitress. She is so good in this role. You feel all the pain, hurt, shame, and frustrations that she is going through while watching her mother again changing boyfriends, this time to Joe. Her reading of the diary later in the storyline will definitely move you.
For a while, you think that this is simply a love story, or a story about Alaska, but it isn't. It could have limited itself to that and it would have been very entertaining. Again, the characters are so perfect.  And, there are the graphic scenes in the salmon packing plant.
When Casey Siemaszko, as Bobby Gastineau, Joe's half-brother shows up, the plot takes off in another direction. Survival becomes the big issue. I keep thinking about the end of the movie. It isn't what I expected. When you leave, take another look at the poster. This film is very good. I want to see it again. I give it a B+.

So far we have discussed two of the three main languages that formulate the modern day web experience. They were HTML (Hyper Text Mark-up Language) and CSS (Cascading Style Sheet. The final of the three the langeuage that is being introduced in this blog is JavaScript (JS).
If the functions of each of those languages for websites were to be described in the simpliest form:
To add further details about Java Script, it is a language that helps the webpage become more interactive for the users. It allows actions/inactions (such as clicks or key-presses) to trigger certain events such as change in website presentation, execution of a calculation or an appearance of a new menu.
Just as we read a book from left to right, from top to bottom, there is a direction and an order in which the browser reads the JavaScript code. This is called the Control Flow. While it seems it should be a straight forward process, after all we just compared it to simply reading a book, the fact that JavaScript is designed to be interactive makes it a little more complicated process.
As a whole, the JavaScript's Control Flow will dictate that the codes should be read line-by-line, from top to bottom. Again, just as if reading a book. However when it comes to functions or number operations, it reads the codes very close to that of a BEDMAS. Meaning it reads what's in the bracket first, then multiplication/division and then addition/subtraction.Quite often, programers will need to maniuplate the direction of the flow. In a situation when a decision needs to be made for one outcome or another, we can use the conditionals such as the if statement. We can use pseudo-code to represent a situation where we can use an if statement, such as when when comming accross a trafic light:
In other occasions, we may want to repeat something a multiple times until a certain condition is met using a loop. For example, we can use cooking a steak as an example of how a while loop can be applied.
Or DOM for short, it is a JavaScript representation of a browser document, namely HTML. The browser creates the DOM so that JavaScript can refer to the HTML and interact with it, without actually changing the content of the HTML itsself.
DOM is represented as what is often called a "DOM tree" (see below). Just as JavaScript can interact with "Objects" and assign properties and values, each of the elements/tags in an HTML document is represented as objects that JavaScript can change or add value to. These objects are modeled into a hierarchical model that reflect the parent-child relationship of different elements in the HTML document.
Document Object Model
We can interact with DOM as if we were to interact with different elements within the DOM using Query Selectors, referencing them via tags, IDs or classes.
Arrays in JavaScript are varaibles that cotain a list of values, for example, like a list of things to bring to a picnic. For example:
Above example shows the array picnicList with 4 different data elements within the array. Each of those element can be accessed by calling upon their indices. Index for any arrays start with 0, not 1. Which means the first item 'Picnic Basket' will have index of 0, and the second item in the array will have index of 1.
Each of the element can be accessed by naming the array name (e.g. picnicList), followed by the index number in a squared bracket. For example:
Objects in JavaScripts are similar to "things". These objects or "things" can have different "characteristics" called properties. For example, an object can be a "car" with properties of blue color, sedan form-factor, make of Honda, model of Civic etc. Each of the object's characteristics consists of key and value. In code, they can be described as follows:
For objects, each of the properties and it's values can be acessed by the following naming the object name (e.g. Car) followed by a dot and the property key. For example:
Same can be achieved by using the square bracket notations and quotation marks instead of a dot. Eg:
From the above examples you can also see that you can also nest an array within an Object. Each of the elements in the "Car" objects can also be referenced by using inicies, just as you would on a any normal array.
Functions are similar to variable, but they hold an "instruction on what to do" rather than a simple data value. For example:
Variable themselves can hold a function as their value. For example:
Declaring a function by itself doesn't do anything, just as how declaring variable itself doesn't do anything either. To call a function, you can invoke by naming the function, followed by self closing brackets. For example:
Just like variables, functions can store complicated operations and computations, and easily be called upon by its name without having to write down all over again. It allows for easier and cleaner codes with less room for bugs or mistakes.

java.lang.Object javax.crypto.CipherSpi
public abstract class CipherSpi
This class defines the Service Provider Interface (SPI)
for the Cipher
class.
All the abstract methods in this class must be implemented by each
cryptographic service provider who wishes to supply the implementation
of a particular cipher algorithm.
In order to create an instance of Cipher
, which
encapsulates an instance of this CipherSpi
class, an
application calls one of the
getInstance
factory methods of the
Cipher
engine class and specifies the requested
transformation.
Optionally, the application may also specify the name of a provider.
A transformation is a string that describes the operation (or set of operations) to be performed on the given input, to produce some output. A transformation always includes the name of a cryptographic algorithm (e.g., DES), and may be followed by a feedback mode and padding scheme.
A transformation is of the form:
(in the latter case, provider-specific default values for the mode and padding scheme are used). For example, the following is a valid transformation:
Cipher c = Cipher.getInstance("DES/CBC/PKCS5Padding");
A provider may supply a separate class for each combination
of algorithm/mode/padding, or may decide to provide more generic
classes representing sub-transformations corresponding to
algorithm or algorithm/mode or algorithm//padding
(note the double slashes),
in which case the requested mode and/or padding are set automatically by
the getInstance
methods of Cipher
, which invoke
the engineSetMode
and
engineSetPadding
methods of the provider's subclass of CipherSpi
.
A Cipher
property in a provider master class may have one of
the following formats:
// provider's subclass of "CipherSpi" implements "algName" with
// pluggable mode and padding
Cipher.
algName
// provider's subclass of "CipherSpi" implements "algName" in the
// specified "mode", with pluggable padding
Cipher.
algName/mode
// provider's subclass of "CipherSpi" implements "algName" with the
// specified "padding", with pluggable mode
Cipher.
algName//padding
// provider's subclass of "CipherSpi" implements "algName" with the
// specified "mode" and "padding"
Cipher.
algName/mode/padding
For example, a provider may supply a subclass of CipherSpi
that implements DES/ECB/PKCS5Padding, one that implements
DES/CBC/PKCS5Padding, one that implements
DES/CFB/PKCS5Padding, and yet another one that implements
DES/OFB/PKCS5Padding. That provider would have the following
Cipher
properties in its master class:
Cipher.
DES/ECB/PKCS5Padding
Cipher.
DES/CBC/PKCS5Padding
Cipher.
DES/CFB/PKCS5Padding
Cipher.
DES/OFB/PKCS5Padding
Another provider may implement a class for each of the above modes
(i.e., one class for ECB, one for CBC, one for CFB,
and one for OFB), one class for PKCS5Padding,
and a generic DES class that subclasses from CipherSpi
.
That provider would have the following
Cipher
properties in its master class:
Cipher.
DES
The getInstance
factory method of the Cipher
engine class follows these rules in order to instantiate a provider's
implementation of CipherSpi
for a
transformation of the form "algorithm":
CipherSpi
for the specified "algorithm".
If the answer is YES, instantiate this class, for whose mode and padding scheme default values (as supplied by the provider) are used.
If the answer is NO, throw a NoSuchAlgorithmException
exception.
The getInstance
factory method of the Cipher
engine class follows these rules in order to instantiate a provider's
implementation of CipherSpi
for a
transformation of the form "algorithm/mode/padding":
CipherSpi
for the specified "algorithm/mode/padding" transformation.
If the answer is YES, instantiate it.
If the answer is NO, go to the next step.
CipherSpi
for the sub-transformation "algorithm/mode".
If the answer is YES, instantiate it, and call
engineSetPadding(padding)
on the new instance.
If the answer is NO, go to the next step.
CipherSpi

slashes).

protected abstract void engineInit(int opmode, Key key, SecureRandom random) throws InvalidKeyException
The cipher is initialized for one of the following four operations:
encryption, decryption, key wrapping or key unwrapping, depending on
the value of opmode
.
If this cipher requires any algorithm parameters that cannot be
derived from the given key
, the underlying cipher
implementation is supposed to generate the required parameters itself
(using provider-specific default or random values) if it is being

requires any random bytes (e.g., for parameter generation), it will get
them from random

Such an override is expected to throw an IllegalBlockSizeException or InvalidKeyException (under the specified circumstances), if the given key cannot be wrapped. If this method is not overridden, it always throws an UnsupportedOperationException.
key
- the key to be wrapped.
IllegalBlockSizeException
- if this cipher is a block cipher,
no padding has been requested, and the length of the encoding of the
key to be wrapped is not a multiple of the block size.
InvalidKeyException
- if it is impossible or unsafe to
wrap the key with this cipher (e.g., a hardware protected key is
being passed to a software-only cipher).protected Key engineUnwrap(byte[] wrappedKey, String wrappedKeyAlgorithm, int wrappedKeyType) throws InvalidKeyException, NoSuchAlgorithmException
This concrete method has been added to this previously-defined abstract class. (For backwards compatibility, it cannot be abstract.) It may be overridden by a provider to unwrap a previously wrapped key. Such an override is expected to throw an InvalidKeyException if the given wrapped key cannot be unwrapped. If this method is not overridden, it always throws an UnsupportedOperationException.
wrappedKey
- the key to be unwrapped.wrappedKeyAlgorithm
- the algorithm associated with the wrapped
key.wrappedKeyType
- the type of the wrapped key. This is one of
SECRET_KEY
, PRIVATE_KEY
, or
PUBLIC_KEY
.

MPInterstitialAdController Class Reference
| Inherits from | UIViewController |
| Declared in | MPInterstitialAdController.h |
Overview
The MPInterstitialAdController
class provides a full-screen advertisement that can be
displayed during natural transition points in your application.
Tasks
Obtaining an Interstitial Ad
-
+ interstitialAdControllerForAdUnitId:
Returns an interstitial ad object matching the given ad unit ID.
Setting and Getting the Delegate
-
delegate
The delegate (
propertyMPInterstitialAdControllerDelegate
) of the interstitial ad object.
Setting Request Parameters
-
adUnitId
The MoPub ad unit ID for this interstitial ad.
property -
keywords
A string representing a set of keywords that should be passed to the MoPub ad server to receive more relevant advertising.
property -
location
A
propertyCLLocation
object representing a user’s location that should be passed to the MoPub ad server to receive more relevant advertising.
Enabling Test Mode
-
testing
A Boolean value that determines whether the interstitial ad object should request ads in test mode.
property
Loading an Interstitial Ad
-
– loadAd
Begins loading ad content for the interstitial.
Detecting Whether the Interstitial Ad Has Loaded
-
ready
A Boolean value that represents whether the interstitial ad has loaded an advertisement and is ready to be presented.
property
Presenting an Interstitial Ad
-
– showFromViewController:
Presents the interstitial ad modally from the specified view controller.
Disposing of an Interstitial Ad
-
+ removeSharedInterstitialAdController:
Removes the given interstitial object from the shared pool of interstitials available to your application.
Handling Custom Event Methods (Deprecated)
-
– customEventDidLoadAd
Notifies MoPub that a custom event has successfully loaded an interstitial.
-
– customEventDidFailToLoadAd
Notifies MoPub that a custom event has failed to load an interstitial.
-
– customEventActionWillBegin
Notifies MoPub that a user has tapped on a custom event interstitial.
Properties
adUnitId
The MoPub ad unit ID for this interstitial ad.
@property (nonatomic, copy) NSString *adUnitId
Discussion
Ad unit IDs are created on the MoPub website. An ad unit is a defined placement in your application set aside for advertising. If no ad unit ID is set, the ad object will use a default ID that only receives test ads.
Declared In
MPInterstitialAdController.h
delegate
The delegate (MPInterstitialAdControllerDelegate
) of the interstitial ad object.
@property (nonatomic, assign) id<MPInterstitialAdControllerDelegate> delegate
Declared In
MPInterstitialAdController.h
keywords
A string representing a set of keywords that should be passed to the MoPub ad server to receive more relevant advertising.
@property (nonatomic, copy) NSString *keywords
Discussion
Keywords are typically used to target ad campaigns at specific user segments. They should be formatted as comma-separated key-value pairs (e.g. “marital:single,age:24”).
On the MoPub website, keyword targeting options can be found under the “Advanced Targeting” section when managing campaigns.
Declared In
MPInterstitialAdController.h
location
A CLLocation
object representing a user’s location that should be passed to the MoPub ad server
to receive more relevant advertising.
@property (nonatomic, copy) CLLocation *location
Declared In
MPInterstitialAdController.h
ready
A Boolean value that represents whether the interstitial ad has loaded an advertisement and is ready to be presented.
@property (nonatomic, assign, readonly) BOOL ready
Discussion
After obtaining an interstitial ad object, you can use loadAd
to tell the object to begin
loading ad content. Once the content has been loaded, the value of this property will be YES.
The value of this property can be NO if the ad content has not finished loading, has already
been presented, or has expired. The expiration condition only applies for ads from certain
third-party ad networks. See MPInterstitialAdControllerDelegate
for more details.
Declared In
MPInterstitialAdController.h
testing
A Boolean value that determines whether the interstitial ad object should request ads in test mode.
@property (nonatomic, assign, getter=isTesting) BOOL testing
Discussion
The default value is NO.
Important: If you set this value to YES, make sure to reset it to NO before submitting your application to the App Store.
Declared In
MPInterstitialAdController.h
Class Methods
interstitialAdControllerForAdUnitId:
Returns an interstitial ad object matching the given ad unit ID.
+ (MPInterstitialAdController *)interstitialAdControllerForAdUnitId:(NSString *)adUnitId
Parameters
- adUnitId
A string representing a MoPub ad unit ID.
Discussion
The first time this method is called for a given ad unit ID, a new interstitial ad object is
created, stored in a shared pool, and returned. Subsequent calls for the same ad unit ID will
return that object, unless you have disposed of the object using
removeSharedInterstitialAdController:
.
There can only be one interstitial object for an ad unit ID at a given time.
Declared In
MPInterstitialAdController.h
removeSharedInterstitialAdController:
Removes the given interstitial object from the shared pool of interstitials available to your application.
+ (void)removeSharedInterstitialAdController:(MPInterstitialAdController *)controller
Parameters
- controller
The interstitial ad object that should be disposed.
Discussion
This method removes the mapping from the interstitial’s ad unit ID to the interstitial ad
object. In other words, you will receive a different ad object if you subsequently call
interstitialAdControllerForAdUnitId:
for the same ad unit ID.
Important: This method is intended to be used for deallocating the interstitial
ad object when it is no longer needed. You should nil
out any references you have to the
object after calling this method.
Declared In
MPInterstitialAdController.h
Instance Methods
customEventActionWillBegin
Notifies MoPub that a user has tapped on a custom event interstitial.
- (void)customEventActionWillBegin
Discussion
Warning: This method has been deprecated. You should instead implement interstitial
custom events using a subclass of MPInterstitialCustomEvent
.
Declared In
MPInterstitialAdController.h
customEventDidFailToLoadAd
Notifies MoPub that a custom event has failed to load an interstitial.
- (void)customEventDidFailToLoadAd
Discussion
Warning: This method has been deprecated. You should instead implement interstitial
custom events using a subclass of MPInterstitialCustomEvent
.
Declared In
MPInterstitialAdController.h
customEventDidLoadAd
Notifies MoPub that a custom event has successfully loaded an interstitial.
- (void)customEventDidLoadAd
Discussion
Warning: This method has been deprecated. You should instead implement interstitial
custom events using a subclass of MPInterstitialCustomEvent
.
Declared In
MPInterstitialAdController.h
loadAd
Begins loading ad content for the interstitial.
- (void)loadAd
Discussion
You can implement the interstitialDidLoadAd:
and interstitialDidFailToLoadAd:
methods of
MPInterstitialAdControllerDelegate
if you would like to be notified as loading succeeds or
fails.
Declared In
MPInterstitialAdController.h
showFromViewController:
Presents the interstitial ad modally from the specified view controller.
- (void)showFromViewController:(UIViewController *)controller
Parameters
- controller
The view controller that should be used to present the interstitial ad.
Discussion
This method will do nothing if the interstitial ad has not been loaded (i.e. the value of its
ready
property is NO).
MPInterstitialAdControllerDelegate
provides optional methods that you may implement to stay
informed about when an interstitial takes over or relinquishes the screen.
Declared In
MPInterstitialAdController.h

Everyone has some personal files that we need to hide containing personal / important info or some STUFF ;)
This STUFF is usually kept inside a complex folder strucutre. Hidden folder inside folder in a recursive manner.
You can do this just by a single command on the terminal -
Open the terminal - Press command + space
Type in
terminal
and press
return. Terminal window would open.
Now type in the following lines.
defaults write com.apple.finder AppleShowAllFiles YES
Press
return
Now all the hidden files would be visible if you go inside the Finder.
In MAC, files or folders beginning with a dot ( . ) are considered to be hidden. So just rename your file, which you want
to hide, to begin with a dot ( . )
Ex-> .hidden
Now, to hide the files, again open the terminal as above. And this time type in this line of code ->
defaults write com.apple.finder AppleShowAllFiles NO
Press
return
This would hide all the files, beginning with a dot ( . )
Great job. You just secured all your STUFF.
