Haizea is currently developed by Borja Sotomayor, a PhD candidate at the University of Chicago. The Haizea system is the brainchild of Borja Sotomayor, Kate Keahey and Ian Foster. The design and main ideas behind the Haizea system were first presented in the paper Combining Batch Execution and Leasing Using Virtual Machines (HPDC, 2008), co-authored by Borja, Kate, and Ian.
Haizea was originally funded, from 2006 to 2008, by NSF grant #509408 "Virtual Playgrounds" as part of the Globus Virtual Workspaces group, headed by Kate Keahey, at Argonne National Laboratory. The Workspaces publications page has an extensive list of papers detailing work on which Haizea builds upon, specially the lease abstraction. From 2008 onwards, development of Haizea was funded by the European Union's FP7 Reservoir project ("Resources and Services Virtualization without Barriers") and by the University of Chicago.
Haizea is kindly hosted at the University of Chicago's PhoenixForge, a collaborative development environment for student projects maintained by the ACM student chapter. Special thanks go out to the ACM student chapter for all their hard work in getting PhoenixForge up and running.
Several people have provided assistance, in one way or another, during the development of Haizea: Javier Fontán, Luis González, Samer Al-Kiswany, Tim Freeman, Ignacio Martín Llorente, Anne Rogers, Rubén Santiago Montero, and Tino Vázquez.


Popular Madzibaba dies
A well respected figure in the apostolic circles of Johanne Masowe church Madzibaba Edward has died.
He was leading congregants at Warren Park shrine in Zimbabwe’s capital city of Harare.
Madzibaba Edward was involved in a car accident in Harare at Kuwadzana round about flyover and died at a local hospital.
According to close church members, the deceased born Edward Manyara will be laid to rest at his rural home in Centinary on Friday.

“Our hearts are bleeding due to the death of our humble and God fearing leader. May his soul rest in peace,” said Madzimai Mary a seven year old church member.

A function that references bindings from local scopes around it is called a 'closure'.
This behavior not only frees you from having to worry about lifetimes of bindings but also makes it possible to use function values in some creative ways.


Mali holds funeral service for 30 slain soldiers
A funeral service has been held for the slain soldiers in Mali. The Defence Ministry held the service for the 30 soldiers in the city of Gao.
The soldiers were killed this week during an attack on an army patrol by extremists near the border with Niger.
Malian army spokesman said the toll rose from 24 to 30 from Monday’s mug.
The deadly attack occured in Tabankort in the northeastern Gao region while soldiers from Mali and Niger were carrying out a joint operation to track extremists.
Women held protests in Gao and Sikasso in the south on Wednesday to pressure the government to better protect soldiers.
More than 100 Malian soldiers have died in the past two months in attacks by armed groups linked to organisations such as the Islamic State group and al-Qaida.

Question
In a 2D matrix of dimensions M*N, find number of “equilibrium” points. A point (i, j) is said to be an “equilibrium” point only if all following conditions hold:
a) sum of rows 1…(i-1) = sum of rows (i+1)…M
b) sum of columns 1…(j-1) = sum of columns (j+1)…N
Solution
This is a generalize question of Equilibrium index.
Refer to Equilibrium index, read this. The idea is to get total sum of array first. Then Iterate through the array calculate left sum == sum / 2.
Equilibrium index of an array is an index such that the sum of elements at lower indexes is equal to the sum of elements at higher indexes. For example, in an arrya A:
A[0] = -7, A[1] = 1, A[2] = 5, A[3] = 2, A[4] = -4, A[5] = 3, A[6]=0
3 is an equilibrium index, because: A[0] + A[1] + A[2] = A[4] + A[5] + A[6]
6 is also an equilibrium index, because sum of zero elements is zero, i.e., A[0] + A[1] + A[2] + A[3] + A[4] + A[5]=0
Well, for Equilibrium Points in 2D Array, should be similar. DIY and leave me a comment!
Code
code for findning EI in 1-D array
public List<Integer> findEI(int[] array) {
List<Integer> ans = new ArrayList<Integer>();
int sum = 0;
for (int i = 0; i < array.length; i++) {
sum += array[i];
}
int runningSum = 0;
for (int i = 0; i < array.length; i++) {
if (2 * runningSum + array[i] == sum) {
ans.add(i);
}
runningSum += array[i];
}
return ans;

This page is dedicated to projects I am currently working on, or the various languages I am attempting to learn. I will be using this to reference various github projects I will be undertaking, as well as showcasing some of the various things I am learning to do with Javascript or other web-based languages.


Sentinel¶
This is a small class that improves upon using a plain object as a sentinel for function arguments when None is a valid parameter and can’t be used as the default. The improvements vs. a plain object are:
Better
__str__
and__repr__
for better messages in logs and stacktraces. Instead of something like'<object object at 0x7ffb4d50e830>'
you get'<not_set>'
Sentinels are picklable

Then, it becomes interesting to use Quickvoxel features such as colormap, blending, brightness and contrast. Each of these feature apply independantly to each volume.

类型运算符
instanceof 用于确定一个 PHP 变量是否属于某一类 class 的实例：
Example #1 对类使用 instanceof
以上例程会输出：
bool(true)
bool(false)
instanceof 也可用来确定一个变量是不是继承自某一父类的子类的实例：
Example #2 对继承类使用 instanceof
以上例程会输出：
bool(true)
bool(true)
检查一个对象是否不是某个类的实例，可以使用逻辑运算符 not。
Example #3 使用 instanceof 检查对象不是某个类的实例
以上例程会输出：
bool(true)
最后，instanceof也可用于确定一个变量是不是实现了某个接口的对象的实例:
Example #4 对接口使用 instanceof
以上例程会输出：
bool(true)
bool(true)
虽然 instanceof 通常直接与类名一起使用，但也可以使用对象或字符串变量：
Example #5 对其它变量使用 instanceof
以上例程会输出：
bool(true)
bool(true)
bool(false)
如果被检测的变量不是对象，instanceof 并不发出任何错误信息而是返回 FALSE。不允许
用来检测常量。
Example #6 用 instanceof 检测其它变量
以上例程会输出：
bool(false)
bool(false)
bool(false)
PHP Fatal error: instanceof expects an object instance, constant given
然而 instanceof 的使用还有一些陷阱必须了解。在 PHP 5.1.0 之前，如果要检查的类名
称不存在，instanceof 会调用 __autoload()。另外，如果该类没有被装载则会产生一个
致命错误。可以通过使用动态类引用或用一个包含类名的字符串变量来避开这种问题：
Example #7 避免 PHP 5.0 中 instanceof 引起的类名查找和致命错误问题
以上例程会输出：
bool(false)
instanceof 运算符是 PHP 5 引进的。在此之前用 is_a()，但是后来 is_a() 被废弃而用
instanceof 替代了。注意自 PHP 5.3.0 起，又恢复使用 is_a() 了。
参见 get_class() 和 is_a()。
User Contributed Notes 18 notes
===============================================================================
You are also able to compare 2 objects using instanceOf. In that case,
instanceOf will compare the types of both objects. That is sometimes very
useful:
===============================================================================
Checking an object is not an instance of a class, example #3 uses extraneous
parentheses.
Because instanceof has higher operator precedence than ! you can just do
===============================================================================
I don't see any mention of "namespaces" on this page so I thought I would chime
in. The instanceof operator takes FQCN as second operator when you pass it as
string and not a simple class name. It will not resolve it even if you have a
`use MyNamespace\Bar;` at the top level. Here is what I am trying to say:
## testinclude.php ##
## test.php ##
## stdout ##
bool(true)
bool(true)
bool(false)
bool(true)
bool(true)
bool(false)
===============================================================================
Posting this so the word typeof appears on this page, so that this page will
show up when you google 'php typeof'. ...yeah, former Java user.
===============================================================================
You can use "self" to reference to the current class:
mymethod(null);
}
return 'works!';
}
}
$a = new myclass();
print $a->mymethod($a);
?>
===============================================================================
Response to vinyanov at poczta dot onet dot pl:
You mentionned "the instanceof operator will not accept a string as its first
operand". However, this behavior is absolutely right and therefore, you're
misleading the meaning of an instance.
means "the class named ClassA is an
instance of the class named ClassB". This is a nonsense sentence because when
you instanciate a class, you ALWAYS obtain an object. Consequently, you only
can ask if an object is an instance of a class.
I believe asking if "a ClassA belongs to a ClassB" (or "a ClassA is a class of
(type) ClassB") or even "a ClassA is (also) a ClassB" is more appropriate. But
the first is not implemented and the second only works with objects, just like
the instanceof operator.
Plus, I just have tested your code and it does absolutely NOT do the same as
instanceof (extended to classes)! I can't advise anyone to reuse it. The use of
raises a warning
"include_once(Object id #1.php) …" when using __autoload (trying to look for
$instanceOfA as if it was a class name).
Finally, here is a fast (to me) sample function code to verify if an object or
class:
===============================================================================
use this to check instance of or you can add the else part inside the if making
it nested if for dual varification.:-
";
break;
}
else{
print "
true (if)";
}
}
}
else{
foreach($array as $element){
if(get_class($element)!=$classname){// or we can use this function to
check the classes inside this array
echo "false (else)";
}
}
}
echo "
true";
}
}
$ob=new Test;
$a=new MyClass();
$array=array($a);
$ob->checkObjectArray($array,'MyClass');
?>
===============================================================================
Please note: != is a separate operator with separate semantics. Thinking about
language grammar it's kind of ridicilous to negate an operator. Of course, it's
possible to negate the result of a function (like is_a()), since it isn't
negating the function itself or its semantics.
instanceof is a binary operator, and so used in binary terms like this
terma instanceof termb
while ! (negation) is a unary operator and so may be applied to a single term
like this
!term
And a term never consists of an operator, only! There is no such construct in
any language (please correct me!). However, instanceof doesn't finally support
nested terms in every operand position ("terma" or "termb" above) as negation
does:
!!!!!!!!!!!!!!term == term
So back again, did you ever write
a !!!!!!!!!!!!= b
to test equivalence?
===============================================================================
If you want to test if a classname is an instance of a class, the instanceof
operator won't work.
Will always output
Not child of it
You must use a ReflectionClass :
isSubclassOf('MyParentClass')) echo 'Child of it';
else echo 'Not child of it';
?>
Will output the good result.
If you're testing an interface, use implementsInterface() instead of
isSublassOf().
===============================================================================
SIMPLE, CLEAN, CLEAR use of the instanceof OPERATOR
First, define a couple of simple PHP Objects to work on -- I'll introduce
Circle and Point. Here's the class definitions for both:
radius = $r;
}
public function __toString()
{
return 'Circle [radius=' . $this->radius . ']';
}
}
class Point
{
protected $x = 0;
protected $y = 0;
/*
* This function is the reason we are going to use the
* instanceof operator below.
*/
public function setLocation($x, $y)
{
$this->x = $x;
$this->y = $y;
}
public function __toString()
{
return 'Point [x=' . $this->x . ', y=' . $this->y . ']';
}
}
?>
Now instantiate a few instances of these types. Note, I will put them in an
array (collection) so we can iterate through them quickly.
setRadius($i);
}
/*
* The setLocation() function is written in the Point class
* definition above, so make sure $item is an instance of
* type Point BEFORE calling it AND to stay out of the ER!
*/
if($item instanceof Point)
{
$item->setLocation($i, $i);
}
echo '$myCollection[' . $i++ . '] = ' . $item . '
';
}
?>
$myCollection[0] = 123
$myCollection[1] = abc
$myCollection[2] = Hello World!
$myCollection[3] = Circle [radius=3]
$myCollection[4] = Circle [radius=4]
$myCollection[5] = Circle [radius=5]
$myCollection[6] = Point [x=6, y=6]
$myCollection[7] = Point [x=7, y=7]
$myCollection[8] = Point [x=8, y=8]
===============================================================================
You can use instanceof also for interfaces.
===============================================================================
use this for cross-version development...
4){
if($IIO_INSTANCE instanceof $IIO_CLASS){
return true;
}
else{
return false;
}
}
elseif(floor(phpversion()) > 3){
return is_a($IIO_INSTANCE, $IIO_CLASS);
}
else{
return false;
}
}
?>
===============================================================================
Example #5 could also be extended to include...
var_dump($a instanceof MyInterface);
The new result would be
bool(true)
So - instanceof is smart enough to know that a class that implements an
interface is an instance of the interface, not just the class. I didn't see
that point made clearly enough in the explanation at the top.
===============================================================================
Cross version function even if you are working in php4
(instanceof is an undefined operator for php4)
function isMemberOf($classename) {
$ver = floor(phpversion());
if($ver > 4) {
$instanceof = create_function ('$obj,$classname','return $obj
instanceof $classname;');
return $instanceof($this,$classname);
} else {
// Php4 uses lowercase for classname.
return is_a($this, strtolower($classname));
}
} // end function isMemberOf
===============================================================================
It seems like instanceOf is using a string comparison. Longer class names take
longer to check in conditional statements
eg.
if ($f instanceOf HelloWorldTestClass)
is much slower than
if ($f instanceOf HWT)
===============================================================================
Sometimes you want to typehint objects INSIDE an array, but I think you can't.
Instead, you can use this function to check the classes inside this array:
===============================================================================
The PHP parser generates a parse error on either of the two lines that are
commented out here.
Apparently the 'instanceof' construct will take a string variable in the second
spot, but it will NOT take a string... lame
class Bar {}
$b = new Bar;
$b_class = "Bar";
var_export($b instanceof Bar); // this is ok
var_export($b instanceof $b_class); // this is ok
//var_export($f instanceof "Bar"); // this is syntactically illegal
//var_export($f instanceof 'Bar'); // this is syntactically illegal
===============================================================================
Negated instanceof doesn't seem to be documented. When I read instanceof I
think of it as a compairson operator (which I suppose it's not).


The Java™ platform was designed with a strong emphasis on security. At its core, the Java language itself is type-safe and provides automatic garbage collection, enhancing the robustness of application code. A secure class loading and verification mechanism ensures that only legitimate Java code is executed.
The initial version of the Java platform created a safe environment for running potentially untrusted code, such as Java applets downloaded from a public network. As the platform has grown and widened its range of deployment, the Java security architecture has correspondingly evolved to support an increasing set of services. Today the architecture includes a large set of application programming interfaces (APIs), tools, and implementations of commonly-used security algorithms, mechanisms, and protocols. This provides the developer a comprehensive security framework for writing applications, and also provides the user or administrator a set of tools to securely manage applications.
The Java security APIs span a wide range of areas. Cryptographic and public key infrastructure (PKI) interfaces provide the underlying basis for developing secure applications. Interfaces for performing authentication and access control enable applications to guard against unauthorized access to protected resources.
The APIs allow for multiple interoperable implementations of algorithms and other security services. Services are implemented in providers, which are plugged into the Java platform via a standard interface that makes it easy for applications to obtain security services without having to know anything about their implementations. This allows developers to focus on how to integrate security into their applications, rather than on how to actually implement complex security mechanisms.
The Java platform includes a number of providers that implement a core set of security services. It also allows for additional custom providers to be installed. This enables developers to extend the platform with new security mechanisms.
This paper gives a broad overview of security in the Java platform, from secure language features to the security APIs, tools, and built-in provider services, highlighting key packages and classes where applicable. Note that this paper is based on Java™ SE version 8.
The Java language is designed to be type-safe and easy to use. It provides automatic memory management, garbage collection, and range-checking on arrays. This reduces the overall programming burden placed on developers, leading to fewer subtle programming errors and to safer, more robust code.
In addition, the Java language defines different access
modifiers that can be assigned to Java classes, methods, and
fields, enabling developers to restrict access to their class
implementations as appropriate. Specifically, the language defines
four distinct access levels: private
,
protected
, public
, and, if unspecified,
package
. The most open access specifier is
public
access is allowed to anyone. The most
restrictive modifier is private
access is not allowed
outside the particular class in which the private member (a method,
for example) is defined. The protected
modifier allows
access to any subclass, or to other classes within the same
package. Package-level access only allows access to classes within
the same package.
A compiler translates Java programs into a machine-independent bytecode representation. A bytecode verifier is invoked to ensure that only legitimate bytecodes are executed in the Java runtime. It checks that the bytecodes conform to the Java Language Specification and do not violate Java language rules or namespace restrictions. The verifier also checks for memory management violations, stack underflows or overflows, and illegal data typecasts. Once bytecodes have been verified, the Java runtime prepares them for execution.
The Java platform defines a set of APIs spanning major security areas, including cryptography, public key infrastructure, authentication, secure communication, and access control. These APIs allow developers to easily integrate security into their application code. They were designed around the following principles:
The java.security.Provider
class encapsulates the
notion of a security provider in the Java platform. It specifies
the provider's name and lists the security services it implements.
Multiple providers may be configured at the same time, and are
listed in order of preference. When a security service is
requested, the highest priority provider that implements that
service is selected.
Applications rely on the relevant getInstance
method to obtain a security service from an underlying provider.
For example, message digest creation represents one type of service
available from providers. (Section 4 discusses message digests and
other cryptographic services.) An application invokes the
getInstance
method in the
java.security.MessageDigest
class to obtain an
implementation of a specific message digest algorithm, such as
SHA-256.
MessageDigest md = MessageDigest.getInstance("SHA-256");
The program may optionally request an implementation from a specific provider, by indicating the provider name, as in the following:
MessageDigest md = MessageDigest.getInstance("SHA-256", "ProviderC");
Figures 1 and 2 illustrate these options for requesting an SHA-256 message digest implementation. Both figures show three providers that implement message digest algorithms. The providers are ordered by preference from left to right (1-3). In Figure 1, an application requests an SHA-256 algorithm implementation without specifying a provider name. The providers are searched in preference order and the implementation from the first provider supplying that particular algorithm, ProviderB, is returned. In Figure 2, the application requests the SHA-256 algorithm implementation from a specific provider, ProviderC. This time the implementation from that provider is returned, even though a provider with a higher preference order, ProviderB, also supplies an SHA-256 implementation.
| Figure 1 Provider searching | Figure 2 Specific provider requested |
The Java platform implementation from Oracle includes a number of pre-configured default providers that implement a basic set of security services that can be used by applications. Note that other vendor implementations of the Java platform may include different sets of providers that encapsulate vendor-specific sets of security services. When this paper mentions built-in default providers, it is referencing those available in Oracle's implementation.
The sections below on the various security areas (cryptography, authentication, etc.) each include descriptions of the relevant services supplied by the default providers. A table in Appendix C summarizes all of the default providers.
Certain aspects of Java security mentioned in this paper,
including the configuration of providers, may be customized by
setting security properties. You may set security properties
statically in the security properties file, which by default is the
java.security file in the lib/security directory of
the directory where the Java™ Runtime Environment (JRE) is
installed. Security properties may also be set dynamically by
calling appropriate methods of the Security
class (in
the java.security
package).
The tools and commands mentioned in this paper are all in the
~jre/bin
directory, where ~jre
stands for
the directory in which the JRE is installed. The cacerts
file mentioned in Section 5 is in
~jre/lib/security
.
The Java cryptography architecture is a framework for accessing and developing cryptographic functionality for the Java platform. It includes APIs for a large variety of cryptographic services, including
For historical (export control) reasons, the cryptography APIs
are organized into two distinct packages. The
java.security
package contains classes that are
not subject to export controls (like Signature
and MessageDigest
). The javax.crypto
package contains classes that are subject to export controls (like
Cipher
and KeyAgreement
).
The cryptographic interfaces are provider-based, allowing for multiple and interoperable cryptography implementations. Some providers may perform cryptographic operations in software; others may perform the operations on a hardware token (for example, on a smartcard device or on a hardware cryptographic accelerator). Providers that implement export-controlled services must be digitally signed.
The Java platform includes built-in providers for many of the most commonly used cryptographic algorithms, including the RSA, DSA, and ECDSA signature algorithms, the DES, AES, and ARCFOUR encryption algorithms, the MD5, SHA-1, and SHA-256 message digest algorithms, and the Diffie-Hellman and ECDH key agreement algorithms. These default providers implement cryptographic algorithms in Java code.
The Java platform also includes a built-in provider that acts as
a bridge to a native PKCS#11 (v2.x) token. This provider, named
SunPKCS11
, allows Java applications to seamlessly
access cryptographic services located on PKCS#11-compliant
tokens.
On Windows, the Java platform includes a built-in provider that acts as a bridge to the native Microsoft CryptoAPI. This provider, named SunMSCAPI, allows Java applications to seamlessly access cryptographic services on Windows through the CryptoAPI.
Public Key Infrastructure (PKI) is a term used for a framework that enables secure exchange of information based on public key cryptography. It allows identities (of people, organizations, etc.) to be bound to digital certificates and provides a means of verifying the authenticity of certificates. PKI encompasses keys, certificates, public key encryption, and trusted Certification Authorities (CAs) who generate and digitally sign certificates.
The Java platform includes APIs and provider support for X.509
digital certificates and Certificate Revocation Lists (CRLs), as
well as PKIX-compliant certification path building and validation.
The classes related to PKI are located in the
java.security
and java.security.cert
packages.
The Java platform provides for long-term persistent storage of
cryptographic keys and certificates via key and certificate stores.
Specifically, the java.security.KeyStore
class
represents a key store, a secure repository of cryptographic
keys and/or trusted certificates (to be used, for example, during
certification path validation), and the
java.security.cert.CertStore
class represents a
certificate store, a public and potentially vast repository
of unrelated and typically untrusted certificates. A
CertStore
may also store CRLs.
KeyStore
and CertStore
implementations
are distinguished by types. The Java platform includes the standard
PKCS11 and PKCS12 key store types (whose
implementations are compliant with the corresponding PKCS
specifications from RSA Security). It also contains a proprietary
file-based key store type called JKS (which stands for "Java
Key Store"), and a type called DKS ("Domain Key Store") which is a
collection of keystores that are presented as a single logical
keystore.
The Java platform includes a special built-in JKS key store, cacerts, that contains a number of certificates for well-known, trusted CAs. The keytool utility is able to list the certificates included in cacerts (see the security features documentation link in Section 10).
The SunPKCS11 provider mentioned in the "Cryptography" section
(Section 4) includes a PKCS11 KeyStore
implementation. This means that keys and certificates residing in
secure hardware (such as a smartcard) can be accessed and used by
Java applications via the KeyStore
API. Note that
smartcard keys may not be permitted to leave the device. In such
cases, the java.security.Key
object reference returned
by the KeyStore
API may simply be a reference to the
key (that is, it would not contain the actual key material). Such a
Key
object can only be used to perform cryptographic
operations on the device where the actual key resides.
The Java platform also includes an LDAP certificate store
type (for accessing certificates stored in an LDAP directory), as
well as an in-memory Collection certificate store type (for
accessing certificates managed in a
java.util.Collection
object).
There are two built-in tools for working with keys, certificates, and key stores:
keytool is used to create and manage key stores. It can
The jarsigner tool is used to sign JAR files, or to verify signatures on signed JAR files. The Java ARchive (JAR) file format enables the bundling of multiple files into a single file. Typically a JAR file contains the class files and auxiliary resources associated with applets and applications. When you want to digitally sign code, you first use keytool to generate or import appropriate keys and certificates into your key store (if they are not there already), then use the jar tool to place the code in a JAR file, and finally use the jarsigner tool to sign the JAR file. The jarsigner tool accesses a key store to find any keys and certificates needed to sign a JAR file or to verify the signature of a signed JAR file. Note: jarsigner can optionally generate signatures that include a timestamp. Systems (such as Java Plug-in) that verify JAR file signatures can check the timestamp and accept a JAR file that was signed while the signing certificate was valid rather than requiring the certificate to be current. (Certificates typically expire annually, and it is not reasonable to expect JAR file creators to re-sign deployed JAR files annually.)
Authentication is the process of determining the identity of a user. In the context of the Java runtime environment, it is the process of identifying the user of an executing Java program. In certain cases, this process may rely on the services described in the "Cryptography" section (Section 4).
The Java platform provides APIs that enable an application to
perform user authentication via pluggable login modules.
Applications call into the LoginContext
class (in the
javax.security.auth.login
package), which in turn
references a configuration. The configuration specifies which login
module (an implementation of the
javax.security.auth.spi.LoginModule
interface) is to
be used to perform the actual authentication.
Since applications solely talk to the standard
LoginContext
API, they can remain independent from the
underlying plug-in modules. New or updated modules can be plugged
in for an application without having to modify the application
itself. Figure 3 illustrates the independence between applications
and underlying login modules:
It is important to note that although login modules are pluggable components that can be configured into the Java platform, they are not plugged in via security Providers. Therefore, they do not follow the Provider searching model described in Section 3. Instead, as is shown in the above diagram, login modules are administered by their own unique configuration.
The Java platform provides the following built-in LoginModules,
all in the com.sun.security.auth.module
package:
Krb5LoginModule
for authentication using Kerberos
protocolsJndiLoginModule
for username/password
authentication using LDAP or NIS databasesKeyStoreLoginModule
for logging into any type of
key store, including a PKCS#11 token key storeAuthentication can also be achieved during the process of establishing a secure communication channel between two peers. The Java platform provides implementations of a number of standard communication protocols, which are discussed in the following section.
The data that travels across a network can be accessed by someone who is not the intended recipient. When the data includes private information, such as passwords and credit card numbers, steps must be taken to make the data unintelligible to unauthorized parties. It is also important to ensure that you are sending the data to the appropriate party, and that the data has not been modified, either intentionally or unintentionally, during transport.
Cryptography forms the basis required for secure communication, and that is described in Section 4. The Java platform also provides API support and provider implementations for a number of standard secure communication protocols.
The Java platform provides APIs and an implementation of the SSL and TLS protocols that includes functionality for data encryption, message integrity, server authentication, and optional client authentication. Applications can use SSL/TLS to provide for the secure passage of data between two peers over any application protocol, such as HTTP on top of TCP/IP.
The javax.net.ssl.SSLSocket
class represents a
network socket that encapsulates SSL/TLS support on top of a normal
stream socket (java.net.Socket
). Some applications
might want to use alternate data transport abstractions (e.g.,
New-I/O); the javax.net.ssl.SSLEngine
class is
available to produce and consume SSL/TLS packets.
The Java platform also includes APIs that support the notion of
pluggable (provider-based) key managers and trust managers. A
key manager is encapsulated by the
javax.net.ssl.KeyManager
class, and manages the keys
used to perform authentication. A trust manager is
encapsulated by the TrustManager
class (in the same
package), and makes decisions about who to trust based on
certificates in the key store it manages.
The Java platform includes a built-in provider that implements the SSL/TLS protocols:
Simple Authentication and Security Layer (SASL) is an Internet standard that specifies a protocol for authentication and optional establishment of a security layer between client and server applications. SASL defines how authentication data is to be exchanged, but does not itself specify the contents of that data. It is a framework into which specific authentication mechanisms that specify the contents and semantics of the authentication data can fit. There are a number of standard SASL mechanisms defined by the Internet community for various security levels and deployment scenarios.
The Java SASL API defines classes and interfaces for
applications that use SASL mechanisms. It is defined to be
mechanism-neutral; an application that uses the API need not be
hardwired into using any particular SASL mechanism. Applications
can select the mechanism to use based on desired security features.
The API supports both client and server applications. The
javax.security.sasl.Sasl
class is used to create
SaslClient
and SaslServer
objects.
SASL mechanism implementations are supplied in provider packages. Each provider may support one or more SASL mechanisms and is registered and invoked via the standard provider architecture.
The Java platform includes a built-in provider that implements the following SASL mechanisms:
The Java platform contains an API with the Java language
bindings for the Generic Security Service Application Programming
Interface (GSS-API). GSS-API offers application programmers uniform
access to security services atop a variety of underlying security
mechanisms. The Java GSS-API currently requires use of a Kerberos
v5 mechanism, and the Java platform includes a built-in
implementation of this mechanism. At this time, it is not possible
to plug in additional mechanisms. Note: The
Krb5LoginModule
mentioned in Section 6 can be used in
conjunction with the GSS Kerberos mechanism.
The Java platform also includes a built-in implementation of the Simple and Protected GSSAPI Negotiation Mechanism (SPNEGO) GSS-API mechanism.
Before two applications can use the Java GSS-API to securely
exchange messages between them, they must establish a joint
security context. The context encapsulates shared state information
that might include, for example, cryptographic keys. Both
applications create and use an
org.ietf.jgss.GSSContext
object to establish and
maintain the shared information that makes up the security context.
Once a security context has been established, it can be used to
prepare secure messages for exchange.
The Java GSS APIs are in the org.ietf.jgss
package.
The Java platform also defines basic Kerberos classes, like
KerberosPrincipal
, KerberosTicket
,
KerberosKey
, and KeyTab
, which are
located in the javax.security.auth.kerberos
package.
The access control architecture in the Java platform protects
access to sensitive resources (for example, local files) or
sensitive application code (for example, methods in a class). All
access control decisions are mediated by a security manager,
represented by the java.lang.SecurityManager
class. A
SecurityManager
must be installed into the Java
runtime in order to activate the access control checks.
Java applets and Java™ Web Start applications are
automatically run with a SecurityManager
installed.
However, local applications executed via the java command
are by default not run with a SecurityManager
installed. In order to run local applications with a
SecurityManager, either the application itself must
programmatically set one via the setSecurityManager
method (in the java.lang.System
class), or java
must be invoked with a -Djava.security.manager
argument on the commandline.
When Java code is loaded by a class loader into the Java runtime, the class loader automatically associates the following information with that code:
This information is associated with the code regardless of
whether the code is downloaded over an untrusted network (e.g., an
applet) or loaded from the filesystem (e.g., a local application).
The location from which the code was loaded is represented by a
URL, the code signer is represented by the signer's certificate
chain, and default permissions are represented by
java.security.Permission
objects.
The default permissions automatically granted to downloaded code include the ability to make network connections back to the host from which it originated. The default permissions automatically granted to code loaded from the local filesystem include the ability to read files from the directory it came from, and also from subdirectories of that directory.
Note that the identity of the user executing the code is not
available at class loading time. It is the responsibility of
application code to authenticate the end user if necessary (for
example, as described in Section 6). Once the user has been
authenticated, the application can dynamically associate that user
with executing code by invoking the doAs
method in the
javax.security.auth.Subject
class.
As mentioned earlier, a limited set of default permissions are granted to code by class loaders. Administrators have the ability to flexibly manage additional code permissions via a security policy.
The Java platform encapsulates the notion of a security policy
in the java.security.Policy
class. There is only one
Policy
object installed into the Java runtime at any
given time. The basic responsibility of the Policy
object is to determine whether access to a protected resource is
permitted to code (characterized by where it was loaded from, who
signed it, and who is executing it). How a Policy
object makes this determination is implementation-dependent. For
example, it may consult a database containing authorization data,
or it may contact another service.
The Java platform includes a default Policy
implementation that reads its authorization data from one or more
ASCII (UTF-8) files configured in the security properties file.
These policy files contain the exact sets of permissions granted to
code: specifically, the exact sets of permissions granted to code
loaded from particular locations, signed by particular entities,
and executing as particular users. The policy entries in each file
must conform to a documented proprietary syntax, and may be
composed via a simple text editor or the graphical
policytool utility.
The Java runtime keeps track of the sequence of Java calls that are made as a program executes. When access to a protected resource is requested, the entire call stack, by default, is evaluated to determine whether the requested access is permitted.
As mentioned earlier, resources are protected by the
SecurityManager
. Security-sensitive code in the Java
platform and in applications protects access to resources via code
like the following:
SecurityManager sm = System.getSecurityManager(); if (sm != null) { sm.checkPermission(perm); }
where perm is the Permission object that corresponds to the requested access. For example, if an attempt is made to read the file /tmp/abc, the permission may be constructed as follows:
Permission perm = new java.io.FilePermission("/tmp/abc", "read");
The default implementation of SecurityManager
delegates its decision to the
java.security.AccessController
implementation. The
AccessController
traverses the call stack, passing to
the installed security Policy
each code element in the
stack, along with the requested permission (for example, the
FilePermission
in the above example). The
Policy
determines whether the requested access is
granted, based on the permissions configured by the administrator.
If access is not granted, the AccessController
throws
a java.lang.SecurityException.
Figure 4 illustrates access control enforcement. In this
particular example, there are initially two elements on the call
stack, ClassA and ClassB. ClassA invokes a method in ClassB, which
then attempts to access the file /tmp/abc by creating an
instance of java.io.FileInputStream.
The
FileInputStream
constructor creates a
FilePermission
, perm
, as shown above, and
then passes perm
to the SecurityManager
's
checkPermission
method. In this particular case, only
the permissions for ClassA and ClassB need to be checked, because
all system code, including FileInputStream
,
SecurityManager
, and AccessController
,
automatically receives all permissions.
In this example, ClassA and ClassB have different code
characteristics – they come from different locations and have
different signers. Each may have been granted a different set of
permissions. The AccessController
only grants access
to the requested file if the Policy
indicates that
both classes have been granted the required
FilePermission
.
The Java XML Digital Signature API is a standard Java API for generating and validating XML Signatures.
XML Signatures can be applied to data of any type, XML or binary (see http://www.w3.org/TR/xmldsig-core/). The resulting signature is represented in XML. An XML Signature can be used to secure your data and provide data integrity, message authentication, and signer authentication.
The API is designed to support all of the required or recommended features of the W3C Recommendation for XML-Signature Syntax and Processing. The API is extensible and pluggable and is based on the Java Cryptography Service Provider Architecture.
The Java XML Digital Signature APIs consist of six packages:
javax.xml.crypto
javax.xml.crypto.dsig
javax.xml.crypto.dsig.keyinfo
javax.xml.crypto.dsig.spec
javax.xml.crypto.dom
javax.xml.crypto.dsig.dom
Additional Java security documentation can be found online at
and in the book Inside Java 2 Platform Security, Second Edition: Architecture, API Design and Implementation.
Note: Historically, as new types of security services were added to the Java platform (sometimes initially as extensions), various acronyms were used to refer to them. Since these acronyms are still in use in the Java security documentation, here is an explanation of what they represent: JSSE (Java™ Secure Socket Extension) refers to the SSL-related services described in Section 7, JCE (Java™ Cryptography Extension) refers to cryptographic services (Section 4), and JAAS (Java™ Authentication and Authorization Service) refers to the authentication and user-based access control services described in Sections 6 and 8, respectively.

An area chart visualization can be thought of as a hybrid between a line and a bar chart. Similar to a line chart, an area chart shows how the numeric values of one or more series change over the progression of another variable, usually time. And, similar to a bar chart, an area chart consists of a shaded area between a baseline (typically zero) and the line representing the numeric values.
In real world scenarios, using an area chart visualization may make the most sense if you want to compare quantities between two or more series by stacking them one on top of another. If, on the other hand, you only have a single series to visualize, it may be more practical to use just a simple bar or line chart, depending of course on what you want to communicate about the data. With that in mind, the first example on this page does show, for simplicity's sake, a single series visualized as an area.
To create a simple area chart, the basic elements you need are much the same as those of a
line chart. The main
differences in usage lie in the use of
AreaRenderer
instead of
LineRenderer
and in the configuration of the data accessors implemented by the
AreaAccessors
class.
When instantiating the AreaRenderer
, you can optionally pass a configuration object of type
IAreaRendererConfig
to make certain modifications to the behavior of the chart.
ChartAssist
since it doesn't
need to either process the stacking of multiple series or handle interaction with an external
component such as a legend. Subsequent examples that include series stacking or legend interaction
will make use of a ChartAssist
instance to handle those tasks.
In the example above, we create an instance of
AreaAccessors
and configure
it to work specifically with the data being fed into the chart. For the standard, horizontally
oriented area chart we provide implementation-specific definitions for the following accessors:
x
accessor for values in the data that correspond to the horizontal axis. Again,
this is typically a datetime value. This value is also used as a coordinate for the data point marker.
y
accessor for values to be used as the y
coordinate for the
data point marker. The y
accessor is assigned the absoluteY1
accessor
which takes into account areas that may be stacked below the current area and retrieves the absolute
distance from the baseline to the area's value line.
y0
accessor for the baseline on the vertical axis which, in this particular case,
will always return the typical baseline value of zero.
y1
accessor for the value line on the vertical axis that provides access to the
numeric values we want to visualize in the data.
Note: For a vertically oriented chart in which the progression runs along the y
axis, you can configure the opposite accessors from those above, i.e. y
,
x0
, and x1
, but with the same corresponding implementations.
In addition to data access, the
AreaAccessors
indicate what
color and marker symbol the chart should use for each series visualization. For additional
information about chart setup, take a look at
this page.
To instantiate a grid that conforms to UX guidelines for area visualizations, we invoke the
areaGrid
function and pass the result to the
Chart
constructor.
As mentioned above, an area chart may be an ideal option if you want to compare a progression of
quantities between two or more series. In that case, you'll likely want to display the series in
a stacked formation, and the easiest way to do that is to pass the
stackedArea
preprocessor to an instance of the previously mentioned
ChartAssist
which will use
the preprocessor to stack the series' numeric values on the same progression domain.
Note: The absoluteY1
accessor is assigned to the y
accessor
to position data point markers in the stacked series correctly.
The use of an unstacked or overlapping area visualization is generally discouraged for a few key reasons:
If you're considering implementing an unstacked area chart, it's a good idea to consider these and other potential drawbacks. While making your considerations, it's possible you'll determine that implementing a line chart instead will result in a better overall experience for your users. If however you find that your use case is extra, super special, and you really, really need an unstacked area chart, please contact the Nova team so that we can show you how to assemble the visualization. Additionally, please consult with Nova Design System leadership before proceeding so that they can work with you to provide the best solution possible.
Stacked percentage area charts are similar to standard stacked area charts in that they facilitate the comparison of quantities between two or more series across the progression of another variable. The difference is that a stacked percentage area chart visualizes each quantity in relation to the sum of all quantities along that progression. It can be thought of as a pie chart with an added dimension, usually time, in which you can see what portion of the sum total each data point represents over a given period of time.
Because of the similarities to standard stacked area charts, the usage for a stacked percentage chart
is much the same but with a minor difference. Instead of passing the stackedArea
preprocessor to the ChartAssist
,
you pass the
stackedPercentageArea
preprocessor which will not only stack the series' numeric values on the same progression domain but
will also vertically scale each series area as a percentage of the sum of all corresponding series
values.
Sometimes the baseline of an area chart isn't fixed at zero. If you have a use case in which the
baseline varies with each data point, you can set the y0
accessor to provide access to
the value in the data to be used as the baseline. In the following example, the data contains
start
and end
properties that are used as the y0
and
y1
values respectively.
To display a progression of two correlated values on opposite sides of a baseline, you can implement
a data accessor that flips the values of one series from positive to negative. In this example, the
positive values for download speed are flipped to negative in that series's y1
data
accessor. Additionally, the example implements a y-scale "tick" formatter to display positive values
for the axis ticks below the zero baseline and in the legend.
If you need to visualize more than one metric per direction, you can set up a bi-directional stacked chart.
The following example demonstrates this by creating two chart instances, each with its own data but acting
as a single visualization. The series on the bottom chart are stacked in a downward direction by invoking
the reverse
method on the chart's y-axis
LinearScale
. For additional details, take a look at
the code and comments in the example's source expander.
To invert the direction of each stack, you can invoke the
reverse
method on the y-axis
LinearScale
of the top chart
instead of the one on the bottom chart. The following example demonstrates
how to do this. For details, take a look at the code and comments in the example's source expander.

As a videogame design leader, my task within the project has been to bring the first ideas that we had to reality, I have made sure that all the gameplay and history that we have designed made sense and were not repetitive for the player trying to have a gameplay funny. As far as implementation I have programmed all the interaction of the xbox controllers, the control configurations and the state machine of each command. I have designed the puzzles that are in the game, always trying to get the players to use the mechanics they have been taught. I have also designed the dungeon with all its enemies and the two puzzles that it has. I have also been in charge of the design of the map, we have had to change the map a few times, but in the end we have done something very faithful to what we wanted.


FASTER, PUSSYCAT! KILL! KILL! A film review by Christopher Null Copyright 1995 Christopher Null
In 1966, Russ Meyer's classic, FASTER, PUSSYCAT! KILL! KILL!, first hit the big screen. 1995 marks the re-release of what is considered the director's best and most accessible work: still as fun, twisted, and hilarious as ever.
The picture opens with an ominous voice-over, reminiscent of an old Ed Wood picture, warning us of the dangers of a certain creature that often "travels in packs." Of course this creature is none other than ... the go-go dancer, which, when released after a hard night's work, has the tendency to wander through the desert looking for trouble.
FASTER, PUSSYCAT! is the story of three such creatures (Tura Satana, Haji, and Lori Williams) who, after a particularly competitive auto race, wind up in a plot involving murder, kidnapping, and the lust for an old man's "stash" of money. It's a thin plot, of course, but the ultra-hammy acting by the three ladies is what really carries the story from one hilarious scene to the next.
The Ed Wood comparisons don't stop at the narration. In many respects, FASTER, PUSSYCAT! is so bad it's good. Satana, Haji, and Williams couldn't act their ways--working together--out of a paper bag. But surprisingly, this works. With the heavy use of '60's hipster-slang and a cool jazz/thriller theme music soundtrack, the three leads are portrayed as anti-heroines of a bygone age. So what if they haven't memorized their lines?
And don't be fooled, Meyer knew what he was doing. The script is full of self-mocking references, with Satana referring to a "scene" or "the screenplay." And as a true master of low-budget filmmaking, Meyer could turn this schlock into profits. While appearing as half-industrial film, half-farce, the sum result is an entertaining fringe picture that's really quite suitable for the mainstream.
As new prints of FASTER, PUSSYCAT! travel around the country, you'll probably hear that Meyer was "a soft-core pornographer" with films like BEYOND THE VALLEY OF THE DOLLS. But when you see this movie (and you really should), you may not even notice: despite the sensationalistic topic and scantily-clad characters, PUSSYCAT has no nudity, due to the heavy censorship activity of the era. Of course, Meyer's reputation is quite the opposite. Meyer fools us all again.

Foundation Story and Philosophy
Cyprus International University ….a truly International experience. CIU Philosophy Cyprus International University is a modern campus University based in the suburb of Haspolat on the outskirts of Nicosia, the capital city of Cyprus. At the corner stone of three continents and rich in terms of history and culture, North Cyprus, the pearl of the Mediterranean, offers a truly international experience. Our mission is to create a truly international experience by developing and disseminating universal knowledge, for the benefit of all society. Much of this is achieved by publishing academic research of an international standard and by specializing in innovative research relevant both locally in North Cyprus and globally. In terms of education CIU creates a truly international experience by attracting academic and administrative staff from all over the world. There is an emphasis on quality and interactive learning in an atmosphere convivial to study. Being a truly international community university environment you will meet students from well over 109 countries in the world, studying together where equality, diversity, freedom of expression and beliefs are cherished and valued. Our students learn to become independent and open-minded, socially responsible members of society, suitably prepared to compete on a world stage. They are exposed to the latest state of the art facilities laboratories workshops and studios and with our comprehensive library service have access to the latest world knowledge in their chosen field of study. CIU adds value across the curriculum, encourages exchanges and works with a range of international academic institutions through partnerships and collaboration activities, providing another example of a truly international experience. CIU History CIU was established on 4th February 1997, after a five-year consultative period to address the Higher Educational needs of the local and international community. In its first year 1997-1998 CIU started with 12 undergraduate programs in three faculties, offering three associate degree programs in one Vocational School in its original location in Nicosia. In the academic year of 2001-2002, CIU relocated to the Haspolat campus, 7 km from the city centre, and opened two dormitory accommodation buildings, an information centre (which also provides the University’s IT support), a student centre, a centre for the University’s senior rectorate and the first faculty building. Currently (2019) the university has Academic Faculties in the following disciplines: In addition, CIU also has three Specialist Schools and a Graduate Institute: The School of Tourism and Hotel Management The School of Applied Sciences offer programmes. The vocational school (offering four programmes of two years duration) The Institute of Graduate Studies and Research (providing co-ordination of the Masters and Postgraduate Research programmes)

The IFDS analysis by Reps et al. is a graph reachability problem that can be used to solve certain static analyses. Both IFDS and its extension IDE can be expressed in Flix. Something which is not possible in pure Datalog.
enum Parity {
case Top,
case Odd, case Even,
case Bot
}
def leq(e1: Parity, e2: Parity): Bool =
match (e1, e2) with {
case (Bot, _) => true
case (Odd, Odd) => true
case (Even, Even) => true
case (_, Top) => true
case _ => false
}
def lub(e1: Parity, e2: Parity): Parity =
match (e1, e2) with {
case (Bot, x) => x
case (x, Bot) => x
case (Odd, Odd) => Odd
case (Even, Even) => Even
case _ => Top
}
A parity analysis aims to discover, for every local variable in a program, whether it is odd or even. We can conveniently express such an analysis as several constraints over a lattice (see above for the lattice definition).

For more serious configuration in production, it is recommended to ommit ConsoleTarget
. For example:
#if DEBUG
static let targets: [Target] = [ConsoleTarget(), FileTarget()]
#else
static let targets: [Target] = [FileTarget()]
#endif
static let config = Config(targets: targets)
LogrService.init(with: config)
The set targets will be used across the whole application.
To log messages, simply create Logr
instance in class initializer and start logging. For example:
import Logr
class ViewController: UIViewController {
private let logr = Logr()
func logDebug() {
logr.debug("debug message to be logged")
}
}
