| SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
This interface is intended to access files or directories that are located on removeable media and/or file systems on a device.
Device internal filesystems in memory may also be accessed through
this class as well, provided there is underlying hardware and OS support.
If file connections are not supported to a particular media or file system,
attempts to open a file connection to the media or file system through
Connector.open()
results in an
javax.microedition.io.IOException
being thrown.
The format of the input string used to access a FileConnection through
Connector.open()
must follow the format of a fully-qualified,
absolute path file name as described by the file
URL format in IETF RFCs 1738 & 2396. Further detail for the File
URL format can be found in the com.siemens.mp.microedition.io.file package description.
A single connection object only references a single file or
directory at a time. In some cases, a connection object can be reused to
refer to a different file or directory than it was originally associated with
(see setFileConnection(java.lang.String)
). In general, the best approach to reference
a different file or directory is by establishing a completely separate
connection through the Connector.open()
method.
File connection is different from other Generic Connection Framework
connections in that a connection object can be successfully returned from
the Connector.open()
method without actually referencing an
existing entity (in this case, a file or directory). This behavior
allows the creation of new files and directories on a file system.
For example, the following code can be used to create
a new file on a file system, where CFCard is a valid existing file
system root name for a given implementation:
try {
FileConnection fconn = (FileConnection)Connector.open("file:///CFCard/newfile.txt");
// If no exception is thrown, then the URI is valid, but the file may or may not exist.
if (!fconn.exists())
fconn.create(); // create the file if it doesn't exist
fconn.close();
}
catch (IOException ioe) {
}
Developers should always check for the file's or directory's existence
after a connection is established to determine if the file or directory
actually exists. Similarly, files or directories can be deleted using the
delete()
method, and developers should close the connection
immediately after deletion to prevent exceptions from accessing a connection
to a non-existent file or directory.
A file connection's open status is unaffected by the opening and closing of
input and output streams from the file connection; the file connection stays
open until close()
is invoked on the FileConnection instance.
Input and output streams may be opened and closed multiple times on a
FileConnection instance.
All FileConnection
instances have one underlying
InputStream
and one OutputStream
. Opening a
DataInputStream
counts as opening an InputStream,
and opening a DataOutputStream
counts as opening an
OutputStream
. A FileConnection
instance can have
only one InputStream
and one OutputStream
open at
any one time. Trying to open more than one InputStream
or more
than one OutputStream
from a StreamConnection
causes an IOException
. Trying to open an InputStream
or an OutputStream
after the FileConnection
has
been closed causes an IOException
.
The skip methode of the InputStream
on a FileConnection
does not skip
the bytes from the current position. It skips the bytes from the begin
of the stream.
The inherited StreamConnection
methods in a
FileConnection
instance are not synchronized. The only stream
method that can be called safely from another thread is close
.
When close
is invoked on a stream that is executing in another
thread, any pending I/O method MUST throw an
InterruptedIOException
. In the above case, implementations
SHOULD try to throw the exception in a timely manner. When all open streams
have been closed, and when the FileConnection
is closed, any
pending I/O operations MUST be interrupted in a timely manner.
Data written to the output streams of these FileConnection
objects is not guaranteed to be flushed to the stream's destination
(and subsequently made available to any input streams) until either
flush()
or close()
is invoked on the stream.
Access to file connections is restricted to prevent unauthorized manipulation
of data. The access security model applied to the file connection
is defined by the implementing profile. The security model is applied on
the invocation of the Connector.open()
method with a valid file
connection string. The mode provided in the open()
method
(Connector.READ_WRITE
by default) indicates the application's
request for access rights for the indicated file or directory and is
therefore checked against the security scheme. All three connections modes
(READ_WRITE, WRITE_ONLY,
and READ_ONLY
) are
supported for a file connection and determine the access requested from the
security model.
The security model is also applied during use of the returned
FileConnection, specifically when the methods
openInputStream()
, openDataInputStream()
,
openOutputStream()
, and openDataOutputStream()
are
invoked. These methods have implied request for access rights (i.e.
input stream access is requesting read access, and output stream access is
requesting write access). Should the application not be granted the
appropriate read or write access to the file or file system by the profile
authorization scheme, a java.lang.SecurityException
is thrown.
File access through the File Connection API may be restricted to files that
are within a public context and not deemed private or sensitive. This
restriction is intended to protect the device's and other users' files and
data from both malicious and unintentional access. RMS databases cannot be
accessed using the File Connection API. Access to files and directories that
are private to another application, files and directories that are private to
a different user than the current user, system configuration files, and
device and OS specific files and directories may be restricted. In these
situations, a java.lang.SecurityException
is thrown from the
Connector.open()
method if the file, file system, or directory
is not allowed to be accessed.
Permissions are the MIDP 2.0 mechanism by which a MIDlet may request security
access to protected APIs or functions. A MIDlet can request access by including the
permissions in the MIDlet-Permissions
and MIDlet-Permissions-Opt
attributes in its JAD or manifest. Table 1 defines the permissions
applicable to the FileConnection APIs, and the API methods that are protected by
those permissions:
Table 1: FileConnection Permissions and Protected Methods
| Permission | Protected API Calls |
|---|---|
javax.microedition.io.Connector.file.read |
com.siemens.mp.microedition.io.Connector methods: open("file://...")
|
javax.microedition.io.Connector.file.write |
com.siemens.mp.microedition.io.Connector methods: open("file://...")
|
Note that the following protected API calls from the Table 1 require both read
and write
permissions:
Connector.open("file://...")
if the FileConnection instance is opened in READ_WRITE
Connector.open("file://...", Connector.READ_WRITE)
FileConnection.setFileConnection("file://...")
It should be noted that the permissions protect API calls, regardless of the
data that is being accessed. For example, a successful grant of READ_WRITE
access to the Connector.open("file://...")
method
allows the application to read/write any file or directory, not just the
file/directory used as the method's parameter. The parameters of the API
calls (which indicate the data being accessed) is not a factor at all in
the granting of the permissions, as dictated by MIDP 2.0 security
definitions. For this reason, it is recommended that a user
interaction mode of "one-shot" be used when user authorization is
required so that the user is notified on every instance that a file or directory
is accessed.

systems a file may be considered to be hidden if its name begins with a
period character ('.'). In the UNIX case, this method may be ignored and
the method to make a file hidden may be the rename()
method.

The IOEventManager class is a pure abstract class that provides an interface to create any input/output event called from a GestureManager object.
The idea of this class is to interface to any event using three functions: IOEventManager::gestureInitialize, IOEventManager::gestureInProgressUpdate and IOEventManager::gestureFinalize.
| IOEventManager::IOEventManager | ( | ) |
|
pure virtual |
gestureFinalize This function is called when the event needs to be finalized
| param | data of the frame needed for the event |
This function should not be called again until IOEventManager::gestureInitialize has been called.
In the example of doing a mouse click and drag this function would unclick the button. In the example of recording a video this function should close the file descriptor.
Implemented in StoreHandMask, SingleClickHoldEventManager, ScrollUpDownManager, and AltTabEventManager.

With the Islands tool you can set the islands on the grid.
Then use the Bridges tool to connect the islands.
All islands must be connected in order for your map to be valid!
Once your map is valid you can play it or contribute your map to our GitHub project.


This middleware will handle requests for .css files. If there is a physical file with a
.css extension then it will serve this file. If there is no .css file on disk but there
is a .less file with the same name, then it will use dotless to compile the less file
into css and send this as the response.
For this to work efficiently you should configure output caching. Without output caching
the .less file will be compiled on every request.
Adding this middleware to the Owin pipeline
builder.Register(ninject.Get<OwinFramework.Less.LessMiddleware>())
.As("Less")
.ConfigureWith(config, "/owinFramework/middleware/less");
The assumes that you are using Ninject as your IoC container, and followed the
getting started walkthrough. If this is not the case
then you will need to adjust the code to work in your application.
Default Configuration
The configuration below is the configuration you will get by default if you do not provide
a configuration for this middleware.
{
"owinFramework": {
"middleware": {
"less": {
"documentationRootUrl": "/owin/less/config",
"rootUrl": "/styles",
"rootDirectory": "~\\styles",
"enabled": true,
"analyticsEnabled": true,
"minify": false,
"traceLog": false
}
}
}
}
Configuration notes
-
You can set the documentationRootUrl to null or
empty to disable this documentation in your production environment.
-
In your production environment you probably want to turn off analytics and
turn on minification.
-
If your .less file is invalid then a blank css response will not be served. In this
situation you can turn on the trace logging and also turn on tracing in the
Owin Framework to see the error that is preventing your .less code from compiling.

Tobacco cessation clinic launched
The facility will help educate users about the ill-effects
by Special CorrespondentA tobacco cessation clinic has been established by the Government Chest Clinic (GCC) on its premises as part of various initiatives undertaken by the GCC marking World COPD (Chronic Obstructive Lung Disease) Day on Friday.
According to Dr. S. Govindarajan, State Nodal Officer, National Tobacco Control Programme, the scope of this clinic will be to educate smokers/tobacco users about the ill-effects of tobacco, provide treatment for asthma, COPD and provide psychological support. The clinic will function on Fridays.
The World COPD Day is observed globally under the auspices of the Global Initiative for Chronic Obstructive Lung Disease (GOLD), a WHO organisation, aiming to improve awareness and care for the potentially fatal disorder. A survey of Global Adult Tobacco Survey (GATS) in 2016-17 revealed that a substantial proportion of men and women had a shot at quitting smoking or tobacco use in any form.
The survey revealed that the number of current tobacco users (69.2%) who wanted to quit and those chewing tobacco (57.8%) was slightly higher than those who attempted in 2009-10, said Dr. Suriya Kumar, State Consultant for National Tobacco Control Programme.

This is a text document formatted in the asciidoctor
style of syntax.
Purpose
index.html is a website landing page for the Anynines PaaS provider.
Build Tool
This project is designed to use the Gradle build tool. So the folder structure reflects the build tool expectations.
There is also a tiny wrapper of tools that allow you to build and run gradle without installing that tool. As a trial to confirm everything is correctly installed, open a terminal command session. Then change directories in the root of this project. Then try a command like:
./gradlew check
| An active internet session is required as is a java runtime environment of JDK7 or more recent. |
First time execution (only) will force Gradle to download several dependencies from the internet. This is to support build script logic and speed things up after the first run.
Provided Scripts
Three build scripts are included and these scripts have the .gradle file suffix. Their name and purpose are :
-
build.gradle - primary tasks needed to build this project
-
gretty.gradle - support tasks that allow you to see how this project looks before deployment to a CloudFoundry platform. It is not needed for deployment, only as a convenience. It runs a local web server using the .WAR file from the prior step. Open a web browser like firefox and enter address
localhost:8080
to see what will be available to users once this .WAR is deployed. -
deploy.gradle - this script copies a .WAR file up to your CloudFoundry account. You will need to have joined anynines.com or another CloudFoundry provider. Your username and password credentials must be entered into the script. Also change the application and uri variables to use your own application name in place of anynines.
gradlew
gradlew -b gretty.gradle appRun
gradlew -b deploy.gradle
In fact, you do not need gradle, this project structure, wrapper or any other pieces. Only the folders and files within the ./webapp folder form the index.html landing page.

Amid KYC/AML – And eCommerce – Biometrics Gain Support
by PYMNTSCustomers want speed and security when transacting online or with various FIs and merchants. The problem is that fraudsters have increasingly been crafting new ways to cobble together new identities – or steal old ones, even from individuals no longer alive. The problem is a global one, as firms strive to satisfy KYC and AML mandates. One possible solution lies with biometrics, as more commerce is done over mobile devices. Many Europeans are warming up to biometrics, according to a recent AML/KYC Tracker.
Data:
34 percent: Share of Europeans who want biometric KYC from their FIs to ascertain consumer identities.
28 percent: Portion of adults in European countries who say credit card and bank onboarding takes too long.
2.5M: Number of Americans affected annually by fraudsters using identities belonging to the deceased.
24 percent: Share of Asia-Pacific banks that cite managing KYC compliance as a top challenge.
$800K: USD equivalent of fines levied on five Tanzanian banks for KYC/AML violations.

A change event listener has been added to the editor so that whenever the form changes, the editor value
is stored in a hidden input using JSON.stringify()
.
The option use_name_attributes
was set to false
to avoid sending the other field with the request.
When the form is submitted only the hidden input is sent in the request. This allows to send data structures like arrays and object.

Mach-E leak reveals a lot about Ford's electric Mustang SUV
Ford's 'Mustang-inspired' electric crossover will be unveiled Sunday night, but you can find out a lot about the Mach-E right now. That's because a forum poster dug up an informational page on Ford's website that revealed trim levels, pricing, pictures and some specs for the SUV. These shots clearly show the two-door crossover in red, which is one of three exterior color options available for its limited edition model. While its Mustang inspiration seems mostly limited to the headlights and taillights, it's at least fairly sleek and imbued with the kind of performance angle Ford is clearly pursuing.
A base Select model starts at about $43k before jumping to Premium, then California Route 1, then the $59,900 limited First Edition and finally the top-of-the-line GT model,which costs about $60k. The base model has around 230 miles of EPA-estimated range, which goes up to 300 miles with an extended battery, while the sporty GT model has AWD, 235 miles of range and an expected 0 to 60 MPH time in the mid 3-second range.

In this how-to tutorial I will use Apache Ant to manage a Citrus project and we will use Ant to execute Citrus test cases. First of all I loaded the latest Citrus release archive to an empty folder on my local storage. Unzip the archive in order to have access to the Citrus binaries and sources.
Preconditions
Before we start lets check that you have the proper software installed on your computer, in order to use Citrus:
So now lets start to set up a new Citrus Java project. In contrast to a Maven generated project we have to create our project structure ourself when using Ant. A good starting point is the samples folder coming with the Citrus release distribution. Here you can see several sample Citrus projects with given folder structure. So lets have a look at a usual Citrus project structure. I am using the Eclipse IDE development tool to set up the new Java project. I am also accessing Ant from the command line in this tutorial so you may also want to install Ant first before continuing. See the Ant homepage for detailed installation instructions.
Have a look at the folder structure I created for our new Citrus project
I created a simple Java project in Eclipse called "citrus-sample". I manually added folders and files to the project as follows. The Citrus project knows three source folders, that are also added to the Java build path as source folders:
As a next step we setup a lib folder for some libraries we need for execution. This includes the Citrus Java archives (citrus-core.jar, citrus-http.jar, etc.) coming from the downladed release archive and all dependency libraries also available in the release archive. Finally what's missing is the Ant build file (build.xml) with following content.
<project name="citrus-sample" basedir="." default="citrus.run.tests" xmlns:artifact="antlib:org.apache.maven.artifact.ant"> <property file="src/it/resources/citrus.properties"/> <path id="maven-ant-tasks.classpath" path="lib/maven-ant-tasks-2.1.3.jar" /> <typedef resource="org/apache/maven/artifact/ant/antlib.xml" uri="antlib:org.apache.maven.artifact.ant" classpathref="maven-ant-tasks.classpath" /> <artifact:pom id="citrus-pom" file="pom.xml" /> <artifact:dependencies filesetId="citrus-dependencies" pomRefId="citrus-pom" /> <path id="citrus-classpath"> <pathelement path="src/it/java"/> <pathelement path="src/it/resources"/> <pathelement path="src/it/tests"/> <fileset refid="citrus-dependencies"/> </path> <taskdef resource="testngtasks" classpath="lib/testng-6.8.8.jar"/> <target name="compile.tests"> <javac srcdir="src/it/java" classpathref="citrus-classpath"/> <javac srcdir="src/it/tests" classpathref="citrus-classpath"/> </target> <target name="create.test" description="Creates a new empty test case"> <input message="Enter test name:" addproperty="test.name"/> <input message="Enter test description:" addproperty="test.description"/> <input message="Enter author's name:" addproperty="test.author" defaultvalue="${default.test.author}"/> <input message="Enter package:" addproperty="test.package" defaultvalue="${default.test.package}"/> <input message="Enter framework:" addproperty="test.framework" defaultvalue="testng"/> <java classname="com.consol.citrus.util.TestCaseCreator"> <classpath refid="citrus-classpath"/> <arg line="-name ${test.name} -author ${test.author} -description ${test.description} -package ${test.package} -framework ${test.framework}"/> </java> </target> <target name="citrus.run.tests" depends="compile.tests" description="Runs all Citrus tests"> <testng classpathref="citrus-classpath"> <classfileset dir="src/it/java" includes="**/*.class" /> </testng> </target> <target name="citrus.run.single.test" depends="compile.tests" description="Runs a single test by name"> <touch file="test.history"/> <loadproperties srcfile="test.history"/> <echo message="Last test executed: ${last.test.executed}"/> <input message="Enter test name or leave empty for last test executed:" addproperty="testclass" defaultvalue="${last.test.executed}"/> <propertyfile file="test.history"> <entry key="last.test.executed" type="string" value="${testclass}"/> </propertyfile> <testng classpathref="citrus-classpath"> <classfileset dir="src/it/java" includes="**/${testclass}.class" /> </testng> </target> </project>
Those who are familiar with Ant will understand this file easily. We used the maven ant tasks in order to download all 3rd party libraries needed for a Citrus run. You need to setup the Maven Ant tasks JAR and the TestNG JAR in the lib directory before executing the build script for the first time. Further a Java classpath is defined with its conventional name "citrus-classpath". The classpath definition includes all Java libraries found inside the lib folder. Besides that the build file declares the TestNG special Ant tasks that help us to execute the tests.
These TestNG Ant task definitions will help to execute Citrus out of a Ant build script. We will handle the execution later in this tutorial in more detail. For now we will start with the "create.test" target. This target creates new test cases for your project. So let us give it a try! I execute the "create.test" target from the command line using my seperate Ant installation. To be honest it is more comfortable to use the built-in Eclipse Ant plugin to execute Ant targets, but I choose the command line first to be more independent from the IDE tool.
The target will prompt for some information when executed, see the output below:
$ ant create.test Buildfile: build.xml create.test: [input] Enter test name: MyFirstTest [input] Enter test description: This is my first Citrus test [input] Enter author's name: [Christoph] [input] Enter package: [com.consol.citrus.ant.sample] [input] Enter framework: [testng] BUILD SUCCESSFUL Total time: 21 seconds
The target will ask you for the name of the test first. After that you give a description for the test. The author's default name is located in the "citrus.properties", but you can also specify another author of course. Same thing with the test's package. In the "citrus.properties" you can define a default package or you can type in another package when prompted.
Now that we have given all information for the test Citrus will create all test files automatically. Let us have a look at the generated files.
The generated files are:
With these two files you are able to run the test. Let us first have a look at the generated XML test description:
<?xml version="1.0" encoding="UTF-8"?> <spring:beans xmlns="http://www.citrusframework.org/schema/testcase" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.citrusframework.org/schema/testcase http://www.citrusframework.org/schema/testcase/citrus-testcase.xsd"> <testcase name="MyFirstTest"> <meta-info> <author>Christoph</author> <creationdate>2009-08-19</creationdate> <status>DRAFT</status> <last-updated-by>Christoph</last-updated-by> <last-updated-on>2009-08-19T11:18:06</last-updated-on> </meta-info> <description>This is my first Citrus test</description> <actions> <echo> <message>TODO: Code the test MyFirstTest</message> </echo> </actions> </testcase> </spring:beans>
Citrus created an empty test case that does nothing but print a simple message to the console. The test is in status "DRAFT" which means it is not finished yet but be aware that the test is executable in this state. In case you need to disable the test because it is not entirely finished yet and may cause failures in a test run you can use the status DISABLED. You may code the test first and then change its status to "FINAL" in order to finally enable the test for execution. Right now we do not want to code any additional logic into the test case for this tutorial, so we change its status right now to "FINAL" and try to execute the test with Ant.
We switch again to the command line to execute the Ant target called "citrus.run.single.test". We are asked to type in the name of the test to execute. In our example we type "MyFirstTest" and Citrus will execute the test.
$ ant citrus.run.single.test Buildfile: build.xml citrus.run.single.test: [echo] Last test executed: Unknown [input] Enter test name: [Unknown] MyFirstTest CITRUS TESTFRAMEWORK Found test 'com.consol.citrus.ant.sample.MyFirstTest' RUNNING CITRUS TESTS ------------------------------------------------------------------------ INIT Found 0 tasks in init phase ------------------------------------------------------------------------ INIT successfully ------------------------------------------------------------------------ STARTING TEST: MyFirstTest Initializing TestCase TestCase using the following global variables: project.name = Citrus sample 1. action in test chain echo TODO: Code the test MyFirstTest TEST FINISHED: MyFirstTest ------------------------------------------------------------------------ FINISH CITRUS TEST ------------------------------------------------------------------------ ________________________________________________________________________ CITRUS TEST RESULTS MyFirstTest : SUCCESS Found 1 test cases to execute Skipped 0 test cases (0.0%) Executed 1 test cases Tests failed: 0 (0.0%) Tests successfully: 1 (100.0%) ________________________________________________________________________ Found 0 tasks after ------------------------------------------------------------------------ FINISH successfully
The execution by test names only is suitable for executing a small amount of test cases. If you want to run a whole package of tests use the package notation instead as it is used in the "citrus.run.tests" target which executes all tests in the package "com.consol.citrus".
The last option you have when executing Citrus is a TestNG suite xml file. TestNG can configure test suites via XML. We have a look at a very simple testng.xml.
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="citrus-samples"> <test verbose="2" name="com.consol.citrus.ant.sample.MyFirstTest" annotations="JDK"> <classes> <class name="com.consol.citrus.ant.sample.MyFirstTest"/> </classes> </test> </suite>
The testng.xml is very powerful and you have a lot of options how to group tests together to suites. Citrus can work on those testng.xml files when executed with Ant.
<testng> <xmlfileset dir="configuration" includes="testng.xml"/> </testng>
That's it! This is how Citrus connects with a normal Eclipse Java project and Ant. With Ant you can integrate your Citrus tests easily in your continuous build environment, so the tests are executed every time something has changed in the code base of your project.

Starting With Composer
I’m just getting started with Composer. I’ve been reading a lot about it and I think it’s the way to go. I don’t know many common developers (like me) that are already using it, but I’m going to give it a go. No more Git articles for you. From now on the two main subjects on my blog will be Composer and Unit Testing, since I decided that’s what I’m going to do next. What is this thing called Composer?
Composer is a tool for dependency management in PHP. It allows you to declare the dependent libraries your project needs and it will install them in your project for you. How does that work?
Well it’s quite easy. All there is to know actually is that there’s two logical parts involved:
- The repository: where all your packages will be stored.
- The command line utility: that will help you manage everything.
-
To install Composer first you have to navigate to your project.
$ cd /path/to/my/project
Then you download Composer into your project
$ curl -s http://getcomposer.org/installer | php
Well, the first time I tried this I ran into a little trouble. I always got the following message:
Some settings on your machine make Composer unable to work properly. Make sure that you fix the issues listed below and run this script again:
The detect_unicode setting must be disabled.
Add the following to the end of your php.ini
:
detect_unicode = Off
If you’re not using the native PHP that comes with your system (I’m assuming you’re using a unix based system) and you’re using something like Mamp, Mamp Pro or even Zend Server you probably need to edit your php.ini file to add that line. However, you must check if the path to your php.ini is correct. In my case I had one of those apps installed and it was checking for the native php.ini path.
To check this, run the following:
$ php -i | grep ini
Then you can update the correct php.ini. Moving forward.
At this point you should have a file called composer.phar in your project root. That is your command line utility. You can check if everything is ok by running the following command:
$ php composer.phar
That will give you all the available commands.
That’s it, that is all you need to know about installing composer into your projects. In the next issue we’ll talk about getting actual packages from http://packagist.org/ and working with them in your projects.
For now, browse the following websites:


CRT Monitor Construction
CRT is an acronym for Cathode-Ray Tube , a CRT lamp equipped with an electron gun. In Polish, the word has been adopted a common short name, a synonym for the expression CRT monitor - that is, the designation of computer monitor models whose display is based on a picture lamp called a picture tube. The proper term is a CRT monitor.

PRINCIPLE OF OPERATION OF THE CRT MONITOR
The principle of creating an image in a color CRT monitor is to send a phosphor layer of three electron beams towards the windshield (one for each component of the RGB color) using three electron guns located at the back of the vacuum tube of the kinescope. These beams are directed by means of a strong magnetic field ( deflecting coils ) so that they hit the appropriate area on the phosphor.Phosphor is a luminous pigment (phosphorus) , a material that has the properties of being luminous when exposed to radiation. When creating an image, the beams sweep the screen along a single horizontal line, called the dial line, from left to right, illuminating the phosphor points and causing them to be lighter or darker depending on the instantaneous voltage controlling the electron department.
Horizontal frequency
frequency at which the monitor draws a single image line, measured in kilohertz [kHz]
After drawing the image line and reaching the right edge of the screen, the beams are temporarily extinguished, after which the deflecting coils direct them to the beginning of the next line towards the bottom of the screen and the process occurs again until the entire screen is filled line by line. When the whole screen is full, the beams are extinguished again, after which the whole cycle of drawing the image begins again from the top of the screen (from the first line).
Refresh Rate (Vertical)
frequency with which the monitor draws the entire screen (all image lines) - given in hertz [Hz]. To avoid screen flicker and eye strain, the vertical image should be drawn 85 times per second (refresh rate 85 Hz)
TYPES OF MASK IN CRT MONITORS
Before the phosphor layer is the so-called mask (ang. shadow mask), which acts as a filter that ensures that the electrons hit the surface of the designated phosphor fields (sub-pixels) - which positively affects the quality of the image.perforated (IBM Delta)
slit
(Trinitron, Diamondtron)
slit-perforated
(NEC Cromaclear)
Perforated mask
appeared in the first CRT monitors, was developed by IBM. Its biggest disadvantage is too large a surface, which reduces the brightness of the image
Slit mask
was first used in NEC Cromaclear picture tubes. It is a compromise between the two previous solutions - at the cost of a slight loss of image quality, two stabilizing wires were abandoned. Also, the cost of producing this mask is much lower
Slit-perforated mask
frequency at which the monitor draws a single image line, measured in kilohertz [kHz]
Prons and cons of CRT monitors
The choice of monitor type depends most on its intended use. CRT monitors have been virtually completely displaced from the market by liquid crystal monitors, but some of their unique properties mean that photographers still use them.
Prons of CRT monitors
fast response time, multi-frequency (resolution can be changed), faithful color reproduction, large viewing angles.
Cons of CRT monitors
average brightness and contrast of the image, large dimensions and weight of the monitor (hence more difficult to adjust), high power consumption, always existing screen protrusion, refresh rate has a significant impact on image quality and eye fatigue, higher electromagnetic radiation emission.
Selection of CRT monitor parameters
In CRT monitors, the actual screen working surface is slightly smaller than declared by the manufacturer, due to the protuberances of the screen that are always present in a CRT monitor. Even in the latest models with almost flat screens (FST - Flat Square Tube) there are slight horizontal bulges.
Useful screen size
diagonal screen size of the monitor (expressed in inches)
Currently, standard resolutions on CRT monitors are e.g. 1024 × 768 (XVGA), 1280 × 1024 (SXGA) and 1600 × 1200 (UXGA). Due to the ability to display multiple resolutions (multiple frequencies), it is only important that the monitor provides the right vertical refresh rate for high resolution.
Resolution
parameter determining the number of pixels of the image displayed on the screen in the current mode of the computer monitor; the resolution is expressed as the number of horizontal and vertical pixels of the image
In a CRT monitor, a physical pixel arranged on the screen surface does not translate directly into a "computer" pixel understood as the smallest element of the image processed by the graphics card. Most often, when working with a CRT monitor, a single pixel computer image generated by a graphics card translates into several physical pixels of the mask.
Therefore, to semantic distinguish the concept of pixel image sent from the graphics card and the pixel of the actual picture tube introduced the concept of a spot. The smaller the spot, the more densely spaced the elements are, which translates into better image sharpness. The most common spot sizes: 0.2mm; 0.24mm; 0.25mm; 0.28mm.
Dot size on the CRT monitor
distance in [mm] between two pixels (triads) in a given CRT.
CRT monitors have horizontal and vertical refresh rates. The vertical refresh rate tells you how many times the screen is drawn per second. The horizontal refresh rate determines how many times a second an electron beam can draw a horizontal line per second. The horizontal frequency has a very high value (expressed in kilohertz), so from a purely practical point of view it is of little importance.
So when we talk about the refresh rate, we always mean the vertical frequency. Frequencies below 80 Hz will quickly tire your eyes (visible flickering of the image), ideally it should be 85-100 Hz at a given resolution.
Refresh rate in the CRT monitor
determines how many times per second the whole image (all lines) is displayed on the monitor screen; expressed in hertz [Hz].
Construction of the LCD monitor
LCD is an acronym for Liquid Crystal Display - a liquid crystal display is a device whose operating principle is based on a change in the polarization of light due to changes in the orientation of liquid crystal particles under the influence of an applied electric field.Operating principle of the LCD monitor
The principle of creating an image in a color LCD monitor is slightly different than in CRT monitors. The electron gun has been abandoned, thanks to which the monitor has much smaller dimensions and weight. The light sources are usually thin fluorescent lamps (or LEDs in much more expensive LED monitors). Light is passed through a polarizing filter that passes light waves at a specific phase. Then the stream of light tafia on the filter with horizontal gaps, then passes through the polysilicon layer called liquid crystals and goes to the second filter with vertical gaps.If the light beam is not refracted by 90° through a layer of liquid crystals, this light will be completely retained on the second filter. However, if the light beam refracts by 90° through molecules of liquid crystals, this light will be given to the screen. Liquid crystal molecules are controlled by transistors - supplying voltage causes proper orientation of the particles and refraction of the light beam by 90° (excitation). Each pixel in the LCD monitor consists of three (so-called triad ) sub-pixels corresponding to RGB colors. Each sub-pixel is controlled independently by a separate transistor.
Dead pixel
is a sub-pixel that does not change its color or does not excite - e.g. as a result of a failure of the control transistor - no refraction of the light beam
Division of matrix in LCD monitors
Passive matrices were used in the early days of LCD technology - individual transistors controlled entire rows and columns of pixels. Monitors based on passive matrices smudged (had slow response time, streaks and shadows appeared).In active matrices , each sub-pixel is controlled by a separate thin-film transistor (TFT - Thin Film Transistor)
Twisted Nematic (TN)
The application of voltage causes the liquid crystal particles to rotate to a position perpendicular to the electrode planes on the opposite walls of the screen, which results in blocking the light.
They have a short response time (less than 8ms), but small viewing angles and poor color reproduction.
Multidomain / Patterned Vertical Alignment (MVA)
MVA: An oblique (torsional) arrangement of liquid crystal particles was used due to the use of polyamide solutions. Twisting allows to obtain an identical image from wide viewing angles over 170 & deg;).
PVA: technology developed by Samsung as an alternative to MVA (another technological process of their production and parameter values).
PVA: technology developed by Samsung as an alternative to MVA (another technological process of their production and parameter values).
(Super) In-Plane Switching (IPS)
In this matrix, the electrodes are placed only on the back wall, and the liquid crystal particles are not twisted. After applying voltage, the "guiding" of light takes place along the shorter edges of the molecules and the image is visible even at a wide angle. The Super I-PS technology introduces broken electrodes arranged in zigzag lines, which further reduces discoloration for large viewing angles.
Prons and cons of LCD monitors
The choice of monitor type depends most on its intended use. LCD monitors have virtually completely displaced CRT monitors from the market, but it does not mean that they are free from any disadvantages.
Prons of LCD monitors
very good image brightness / contrast, very good image geometry, low power consumption, small size and weight (hence easy adjustment), perfectly flat monitor, much lower electromagnetic radiation emission than in CRT, low importance of refresh rate for image quality.
Cons of LCD monitors
optimal image only for native resolution, average response time, worse color reproduction than in CRT, image quality depends on the viewing angle.
SELECTION OF LCD MONITOR PARAMETERS
In LCD monitors, the screen diagonal is exactly what the manufacturer declares, because the LCD panels have perfectly flat screens.
Useful screen size
diagonal screen size of the monitor (expressed in inches)
LCD monitors have a native resolution - they display an optimal image in only one resolution, the other modes are obtained by mathematically scaling the image, which significantly reduces its quality.
Resolution
parameter specifying the number of pixels of the image displayed on the screen in the current mode of the computer monitor; the resolution is expressed as the number of horizontal and vertical pixels of the image
The pixel size directly depends on the size of the LCD screen and its natural resolution. To calculate the pixel size, simply measure (or look at the specifications) the width of the screen's working surface and divide it by horizontal resolution - e.g. a 19 inch monitor is usually 376 mm wide and its typical horizontal natural resolution is 1280px. So: 376/1280 = 0.294 mm. Pixel size differences for stationary LCD panels reach 16.5%, but when we consider the matrixes in notebooks, the differences reach up to 36%, and that's a lot.
Consider a 17 inch LCD panel with a resolution of 1280x1024 and a monitor one step larger (i.e. 19 inch) having the same native resolution. A monitor with a larger diagonal will necessarily have a much larger pixel.
The pixel size of the LCD monitor
distance in [mm] between two pixels in a given LCD matrix.
The panel brightness has a significant impact on the variety of colors displayed and the ability to present image details. Example value: 250 cd / m² (for comparison, the typical brightness of a CRT monitor is approx. 100 ÷ 120 cd / m²). Of course, this is the maximum brightness; e.g. during office work, too much brightness can quickly get tired of your eyesight.
Some monitors have switchable modes that change the brightness (and other parameters, such as color balance) so that the displayed content looks the best - a high-brightness profile was created for movies or games, while in office work we use a low-brightness profile.
LCD monitor brightness
maximum brightness obtainable in the LCD matrix, measured in cd / m² (number of candelas per square meter).
Let's talk about the contrast of the image. Example value: 1000: 1. Theoretically, the higher the contrast ratio, the better the panel display options become. It is worth recalling that LCD panels have big problems in presenting blacks, which sometimes can be more dark green than black. Manufacturers of LCD monitors often specify in the device specifications dynamic contrast, which can reach up to 1,000,000: 1 as opposed to much lower static contrast. However, this is a purely marketing procedure.
LCD monitor image contrast
determines the difference between the brightness of the lightest shade of white and the darkest shade of black that can be obtained on the display.
The trick with dynamic contrast is to adjust the brightness of fluorescent lamps giving light depending on the brightness of the image. The difference in brightness of the lamp providing light artificially increases the difference in brightness of white and black color. Dynamic static contrast is poor for static images (e.g. slide presentations) because the slide brightness will change noticeably when you change the slide, however, when you view movies, the changes in lamp brightness will not be as visible, and the movie will appear more contrasting, although it will it looked worse than on a device with a higher static contrast. A monitor or TV with dynamic contrast enabled is not suitable for computer work, especially when it comes to processing documents or graphics.
D'SUB analog connector (VGA)
A connector popular at the time of CRT monitors - undesirable in an LCD monitor, because there is a double signal conversion: conversion of digital signal into analog in the graphics card and analog signal to digital in the monitor. Double conversion causes loss of image quality and increases the sensitivity to interference. The name DSUB comes from a type of connector resembling the shape of the letter D. Another name is VGA (from graphic mode).Digital connector DVI (Digital Video Interface)
The digital video transmission standard in DVI-I and DVI-A also enables analogue signal transmission. The cable connecting the monitor to the computer cannot be longer than 5m.
DVI-D
a truly digital image transmitted between the digital output of the graphics card and the digital input of the monitor.
DVI-A
used to connect a modern graphics card with DVI output to a monitor with analog input.
DVI-I
provides the ability to send an analog source signal to an analog monitor as well as a digital source signal to a digital monitor.
The difference between Single Link and Dual Link inputs is doubled in power, speed and transmission quality for Dual Link inputs.
Modern HDMI digital connectors and Display Port
HDMI connector (High Definition Multimedia Interface) is a digital standard for audio / video signal transmission enabling high definition (HD) transmission and multi-channel audio. We use it in DVD players, Blu-Ray, LCD and plasma TVs as well as game consoles. Maximum cable length: 15m.Display Port connector - the main purpose of the new standard is a computer-monitor or computer-home cinema system connection (including e.g. projectors, TV sets, etc.). DisplayPort already achieved in its first version 1.0 what HDMI managed to achieve only in version 1.3b, i.e.: maximum resolution of 2560x1600, 24 bit color depth, maximum signal throughput around 10 Gb / s. We are able to achieve full specification on a 15-meter cable, with longer cables the resolution is reduced to 1920x1080.
The future of monitors and displays?
Manufacturers are constantly trying to create new technologies that will provide even better parameters of the displayed image, while reducing production costs. What technology will master the market in the near future? What are the innovative methods of display construction?
PDP (Plasma Display Panel)
plasma cathode ray tubes use the properties of noble gases, which when excited by high voltage go into the state of so-called plasma. This reaction takes place simultaneously in several million pixels on the entire screen. Each pixel consists of three so-called sub-pixels for the primary colors: RGB (red, green and blue). The sub-pixel is a glass tube with xenon, at its ends there are electrodes to which high voltage is applied. A potential difference of several hundred volts converts gas into plasma, resulting in UV radiation. Ultraviolet radiation is not visible to humans, so a layer of phosphorus was placed, which when stimulated by this radiation emits visible light.
OLED (Organic Light-Emitting Diode)
so called organic LEDs. The discovery of an organic compound emitting visible light as a result of current flow was made in the University of Cambridge laboratory, but a real breakthrough in this technology took place in 2007. Sony has presented a small, flexible 2.5-inch display and an 11-inch TV with a resolution of 960 × 540 pixels and a contrast of 1,000,000: 1. It is only 3 mm thick! The receiver weighs about 2 kg and has an HDMI connector. The disadvantage of OLED displays is the limited lifetime of organic materials. The raw material for the production of luminous organic diodes is an organic polymer, previously known as a raw material for products made of foil and other materials. By placing such a conductive polymer between two electrodes, on which there is a potential difference, we obtain the current flow and the accompanying light radiation.

Hacking HTML5 Xonix
Time for yet another casual hack of a little browser game that hasn’t been secured. A game called “Xonix” was released for DOS in 1984. It involved incrementally tracing areas on a grid while avoiding moving dots, and when an area is outlined, it would be filled in automatically. As the levels increased in difficulty, the goal was to get a certain percentage of the grid filled in without running out of lives. Some of you might be familiar with this style of game — this may in fact be the first of it’s kind!
Anyway, there have been subsequent ports and clones of this game, and in 2012 two guys ported Xonix to HTML5 such that it can be played in a browser. It’s pretty fun, but as usual I want to take the easy way out, so out come the dev tools!
Unlike the previous game, the developers were a bit more efficient, in that they don’t bother sending a score if it’s you haven’t defeated the top 15 on the high-score list. The only request made on losing is one to get the top N players. I wasn’t about to actually try and win, so I set an XHR breakpoint for any requests, to see where this one fires.
After some snooping around where it does fire, I found the check it does before submitting the score. The devs had everything nice and wrapped up in a little function I can call from the console:
LeaderBoard.set("amar.io", 44488, Game.LEADERBOARD, function(){});
And, voilà, top of the leaderboard!
Poor Daniel Shapira, assuming he got those scores fairly, must be raging pretty hard right about now. Sorry Daniel!
Bonus round!
While probing around a little more, I tried changing the parameter for the number of entries when retrieving the high-score list. When I set it to a huge number, it spits back a nasty stack trace (turns out they’re using Google App Engine with Python in the back end) and crashed the server. I felt pretty bad, but fortunately after a very short period of time it was back up. That’s the extent of the issue though, since when fingerprinting MySQL, the server returns:
Traceback (most recent call last):
File "/base/data/home/runtimes/python/python_lib/versions/1/google/appengine/ext/webapp/_webapp25.py", line 715, in __call__
handler.get(*groups)
File "/base/data/home/apps/s~html5xonix/1.357745203681401670/leaderboard.py", line 17, in get
count = int(cgi.escape(self.request.get('count')))
ValueError: invalid literal for int() with base 10: '1 /*! and 1=0 */'
You can actually see the line of python that they use to get the “count” parameter and escape it, then convert it to an integer. The same thing happens with submitting a name to the list; it escapes all HTML entities and doesn’t seem vulnerable to injections. They’re most likely not even using SQL since it returns JSON documents.
Good on ya, devs!
