My full name is Julio César Carrera. Currently 25 years old and graduated from Northeastern Illinois University(NEIU) in Chicago which is where I still live. I earned a Bachelor's in Computer Science. At NEIU my specific two Computer Science concentrations were Technical Programming, and Information Technology. I also have a Minor in Communications because I figured that it wouldn't hurt, plus communication will be very important wherever I go, and I was also able to fit this Minor with my Computer Science courses.
To be honest I did not know that I wanted to major in CS when I started at NEIU. I had no idea what I wanted to do, but I did know that I was good with computers and liked being challenged with new things. I like to be always learning and finding out how the new can be a total game-changer to the old. I tried out Programming I together with Discrete Mathematics and I loved it. After that I started to think differently about how software world works. I would try to point out where loops were used, what kind of data structure a system might have and so on. I would see microwave ovens, mobile phones, street lights, and anything electronic in a curious manner. Experiencing new subjects about software programming was what kept me entertained at the end of my journey at NEIU. The last two semesters at NEIU I was able and happy to be in The Dean's list for Computer Science.
I really enjoyed creating websites, applications, and other smaller pieces of software after the introductory programming courses. My most challenging course was my Mobile Applications class. But it is also the course where I learned the most. The first day of class our professor told us that if we were not willing to put in AT LEAST 10-15 hours a week of study time outside of class, we should not expect to pass it. At first I was a little bit intimidated, but I did my best going over the material and visiting the professor several times along with other classmates. I really enjoyed those study sessions talking with others on where we would get stuck and trying to troubleshoot our applications. I spent a lot of time on that class and it was worth it because I learned so much, got an A, and made friends in the process.
In addition to programming, I like to play the guitar. I have two acoustic ones, and three electrical. When I was around 14 I played Guitar Hero with my sister and got bored of all available songs. I wanted to play my own stuff and experiment with everything a guitar has to offer. I learned by myself after my parents gifted me my first guitar at 16 years old. I also like making pizzas. This began when I would have super long study sessions and there were no open food places late at night. I began experimenting putting pizzas with different cooking methods and ingredients. I also love driving either really early or late at night when the traffic is almost non-existent. It is very de-stressing for me and a good alternative to exercising.


codeable_models.CObject¶
-
class
codeable_models.
CObject
(cl, name=None, **kwargs)¶ CObject
is used to define objects. Objects in Codeable Models are instances of classes (defined usingCClass
).Superclasses:
CBundlable
- Parameters
Examples:
An example object definition is:
basic_pen = CObject(product, values={"id": "P001", "name": "Basic Pen", "price": 1.50})
Here an unnamed object is derived from class
product
with two string valuesid
andname
, as well as a float valueprice
. The following defines the same object, except that it uses an object name instead of defining a name as an attribute value:basic_pen = CObject(product, "Basic Pen", values={"id": "P001", "price": 1.50})
Main Relations:
The main relations of
CObject
are shown in the figure below.Each
CObject
can be used in bundles through its superclassCBundlable
. Objects are instances of typeCClass
.Each
CClass
has oneclass object
, a special object to manage the instance relation of a class to its meta-class. For instance, the values of meta-class attributes and links for meta-class associations are stored and managed via wrapper methods onCClass
that call the respective methods of theclass object
.Each object can be source or target of a link. Links are only valid, if there is an association between the classes of the objects to be linked (and multiplicities are correctly set on these associations). The association is the classifier of the link (thus it inherits from
CClassifier
), and the link is interpreted as an instance of the association (thus it inherits fromCObject
).-
add_links

Since it’s launch, wepay has been a great payment gateway which provides best user experience along with developer friendly integration. I use this for a number of web and mobile apps and feel that this is one of the best way to handle one time purchases, recurring payments and etc. without having to store any details of the customer’s credit card.
I am going to share a few ideas on how to integrate wepay with your rails/sinatra app.
Getting Started -
Wepay has an excellent developer’s site which has every single detail you may expect as a beginner. Their support is very responding and helpful. Will mention some of the important links below so you can get some help and start.
- Developers site - https://www.wepay.com/developer
- API documentation - https://www.wepay.com/developer/reference
- SDKs - https://www.wepay.com/developer/resources/sdks
- Some use cases -
Find some implementation specific details below.
Implementation with ruby -
We can use wepay’s ruby SDK to integrate your rails/sinatra app with wepay. But i m going to do this by using one of the gems we developed for ourselves. Either should do fine.
Source - https://github.com/udayakiran/wepay_client
Please refer README for details on how to use this.
Setup and usage
Setup
In rails put following in Gemfile
Usage
Create a wepay_config.rb in config/initializers folder and setup the client with wepay client id and client secret
An example to call wepay apis
Alternates -
As mentioned above, Wepay provides a ruby SDK for the same purpose - https://github.com/wepay/ruby-sdk
wepay’s SDK can be used if you find it more comfortable. We started this wepay_client gem during the initial days when there was no ruby SDK from wepay. There are a few differences in the design and i think we are doing a little better job of handling exceptions and converting response to proper ruby objects.
However, both of these sever the same purpose. So, either can be chosen without a thought. We try our best to keep this gem up to date and well maintained.

Why it’s important to self-isolate
Self-isolating when you have coronavirus (COVID-19) or have been in close contact with someone who has the virus can stop it spreading to other people.
Coronavirus can spread though:
- coughs and sneezes
- tiny droplets when you breathe or speak
- touching objects and surfaces with the virus on them
People who have coronavirus can infect others from around 2 days before their symptoms start, and for up to 10 days after. Self-isolating for 10 full days can help stop the spread.
Why you still need to self-isolate if you do not have symptoms
It’s important to self-isolate even if you feel well.
It can take several days for symptoms of coronavirus to appear. You could have the virus but not know it yet.
About 1 in 3 people with the virus do not get symptoms, but can still spread it to other people.
Why the people you live with are asked to self-isolate
Coronavirus spreads more easily when people are close to each other, especially when they’re inside without regular fresh air.
If you have coronavirus, any people you live with are at high risk of getting it too.
They could spread it to others even if they feel well, which is why they may also be asked to self-isolate.
Self-isolation is a legal requirement
As self-isolation is so important, it's a legal requirement to do it if you test positive or are told to by NHS Test and Trace. You could be fined if you do not self-isolate.

Apache Tomcat 6
How to Install & Configure
Apache Tomcat is the official Reference Implementation (RI) for Java Servlets and JavaServer Pages (JSP). Tomcat is an open-source project, under the "Apache Software Foundation" (which also provides the famous open-source industrial-strength Apache HTTP Server). The mother site for Tomcat is http://tomcat.apache.org.
This configuration guide is NOT meant for production purpose, but merely for teaching and self-learning. This guide is applicable to Tomact 6.0.x. Read "Tomcat 7 - How to Install and Configure" for Tomcat 7.
This guide is applicable to my EE3072 Module P311.
Step 0: Read the Tomcat Documentation
Aaviable at Tomcat mother site (@ http://tomcat.apache.org). Select the documentation ⇒ Tomcat 6.0.
Step 1: Download Tomcat
- From http://tomcat.apache.org ⇒ Select "Downloads" ⇒ "Tomcat 6.0" ⇒ "6.0.xx" ⇒ "Binary Distributions" ⇒ "Core" ⇒ "zip" ⇒ "
apache-tomcat-6.0.xx.zip
". - UNZIP into a directory of your choice (says "
c:
"). Tomcat will be unzipped into directory "c:\apache-tomcat-6.0.xx
". I shall refer to the Tomcat installed directory as$CATALINA_HOME
or%CATALINA_HOME%
hereafter (Catalina
is the codename for Tomcat 5 and above. The earlier versions are simply codenamed Tomcat). I recommend "zip" version, as you could simply delete the entire directory when Tomcat is no longer needed without running any un-installer. You could also rename the Tomcat's installed directory to a shorter name (saysc:\Tomcat6
).
Step 2: Create Environment Variable
- Create an environment variable called "
JAVA_HOME
" and set it to the JDK installed directory (e.g.,c:\program files\java\jdk1.6.0_xx
). - In Windows XP/Vista/7: Click "Start" button ⇒ "Control Panel" ⇒ "System" ⇒ (Vista/7) Advanced system settings ⇒ "Advanced" ⇒ "Environment Variables" ⇒ "System Variables" ⇒ "New" ⇒ Enter "
JAVA_HOME
" in the "Variable Name" and your JDK base directory (e.g., "c:\program file\java\jdk1.6.0_xx
") in the "Variable Value". - To verify, start a CMD shell and issue:
> set JAVA_HOME JAVA_HOME=c:\program file\java\jdk1.6.0_xx
Step 3: Configuring "$CATALINA_HOME\conf\server.xml"
TCP Port Number: The default TCP port number configured in Tomcat is 8080, you may choose any number between 1024 and 65535 to run your Tomcat Test server. We shall stick to port 8080 in this article. (For production server, you should use port 80, which is pre-assigned to HTTP as the default port.)
 <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
Context: A web context is simply a web application running under Tomcat Server. To create a new web applicaiton, add your application's "path
" (URL path used by users to access your application) and provide the "docBase
" (directory where you store your application codes), before the </Host>
end-tag, as follows:
...... ...... <Context path="/ws" docBase="d:/workshop" reloadable="true"> </Context> </Host> </Engine> </Service> </Server>
Explanation:
- The "
path
" attribute refers to the URL Path used by the users to access you web application. In the above example, a context path "/ws
" is defined. To access this application, users issue URL http://hostname:8080/ws. - The "
docbase
" attribute refers to the Document Base Directory (also known as the Context Root) in your server’s file system where you store your application's codes. In the above example, the document base directory for context "/ws
" is located in directory "d:\workshop
". - It is important to note that the configuration create a mapping from the "URL Path" issued by the user to the "Document Base Directory" in the server's file system, where you store your application codes.
- Use Unix-style forward slash
'/'
as the directory separator in the configuration file, instead of Window-sytle back slash'\'
. - The attribute
reloadable="true"
asks tomcat to monitor your servlets for changes, and automatically reload the servlets if changes is detected. This is handy for a development system, but inefficient in a production system.
In your application's context root "d:\workshop
":
- Create a sub-directory "
WEB-INF
" (in uppercase with a "dash" - case sensitive!) under "d:\workshop
". - Create a sub-sub-directory "
classes
" (in lowercase - case sensitive!) under "d:\workshop\WEB-INF
". This is where you should keep all your servlet classes.
Note: This configuration is meant for my laboratory class, where each student is given a dedicated directory in another drive. For production, it is recommended that you store your application under "$CATALINA_HOME/webapps
". In this case, you do not have to write the <Context>
explicitly. A context will be automatically generated based on your application's directory name. For example, if your directory is called "eshop
", a context called "eshop
" will be created automatically.

" configuration file.]
Step 4: Configuring "conf\web.xml" and "conf\context.xml" for "Invoker Servlet"
WARNING: The so-called "Invoker Servlet" that we are going to use is an evil (see Tomcat's FAQ @ http://wiki.apache.org/tomcat/FAQ/Miscellaneous on why is it evil), and should not be used for production purpose. But it is really a quick and dirty way for my teaching classes, and I shall continue to use it for teaching.
"$CATALINA_HOME\conf\web.xml": Enable the Directory Listing
<servlet> <servlet-name>default</servlet-name> <servlet-class> org.apache.catalina.servlets.DefaultServlet </servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> |
← The default servlet name ← The default servlet class ← Directory Listing ← Change from "false" to "true" to enable directory listing |
Note: If the listing is enabled, Tomcat will display the directory listing when user issues an URL to a directory. Otherwise, Tomcat returns an error "404 Page Not Found". Again, enabling directory listing is handy in testing, but poses security risk in production.
"$CATALINA_HOME\conf\web.xml": Enable "Invoker Servlet" and Specify its URL Mapping
 ......   |
← Remove this line (comment begin) ← Remove this line (comment end) ← Remove this line (comment begin) ← Remove this line (comment end) |
"$CATALINA_HOME\conf\context.xml": Enable privilege for "Invoker Servlet"
We need to grant privilege (evil!!!) to the "Invoker Servlet" by changing the <Context>
begin-tag in "conf\context.xml
":
<Context privileged="true" reloadable="true">
......
......
</Context>
Note: In this configuration, we actually grant privilege to all the applications system-wide, which is really a big evil!
[Click HERE (right-click and "Saved Link As") to download the "web.xml
" configuration file.]
[Click HERE (right-click and "Saved Link As") to download the "context.xml
" configuration file.]
So what is this evil Invoker Servlet?
 The proper way to deploy servlets is to configure each and every servlet in the application's configuration file. This is tedious (and problematic in my teaching classes).
Suppose that we have a context "ws
" with document base of "d:\workshop
", and we have created a servlet called "TestServlet.class
". With the Invoker Servlet enabled, we could simply drop our servlet into the application's "WEB-INF\classes
" (i.e., "d:\workshop\WEB-INF\classes\TestServlet.class"
). Users can request this servlet via URL http://hostname:8080/ws/servlet/TestServlet
. In other words,, the URL path "servlet
" is mapped to "WEB-INF\classes
".
Step 5: Start the Tomcat Server
You can start the Tomcat Server by running "$CATALINA_HOME\bin\startup.bat
". A new console window will be started (as shown below). Study the messages (especially the Tomcat's port number). Future error messages will be send to this console window. System.out.println()
issued by our servlets will also be sent to this console.
... change directory to $CATALINA_HOME\bin ...
> startup
......
......
Oct 20, 2009 10:56:37 PM org.apache.coyote.http11.Http11Protocol init
INFO: Initializing Coyote HTTP/1.1 on http-8080
......
Oct 20, 2009 10:56:46 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 9215 ms
Start a browser and issue URL "http://localhost:8080
" to access the Tomcat home page (as shown), and URL "http://localhost:8080/ws
" to access your web application "/ws
". localhost (with IP address of <IP_ADDRESS>) is meant for local loop-back testing only. For users on the other machines over the Internet, they have to use the proper IP address or DNS hostname to access the server.
You can shutdown the server by running "$CATALINA_HOME\bin\shutdown.bat
". If Tomcat does not respond to the shutdown
command, you could terminate Tomcat by pressing Ctrl-Break (or Ctrl-C) on the Tomcat's console window. But do not kill the cat by pressing the "close" button.
Step 6: Java Servlet JAR file
Servlet API is needed to compile Java servlet. Servlet API is not part of JDK (but belongs to Java EE). Tomcat also included a copy of Servlet API. For simplicity, you could COPY the Servlet jar-file "$CATALINA_HOME\lib\servlet-api.jar
" into your JDK's extension directory "$JAVA_HOME\jre\lib\ext
" (where $JAVA_HOME
is the JDK installed directory).
Alternatively, you could include the Servlet jar- file in the CLASSPATH
.
Step 7: Write and Deploy a Test Java Servlet
Write the following servlet called "EchoServlet.java
" and save it under your application's "WEB-INF\classes
" (i.e., "d:\workshop\WEB-INF\classes\EchoServlet.java
". Compile the source into "EchoServlet.class
".
import java.io.*; import javax.servlet.*; import javax.servlet.http.*; public class EchoServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); out.println(""); out.println("<title>Servlet Test</title>"); out.println(""); out.println("
Hello,
"); out.println("
Request URI: " + request.getRequestURI() + "
"); out.println("
Protocol: " + request.getProtocol() + "
"); out.println("
PathInfo: " + request.getPathInfo() + "
"); out.println("
Remote Address: " + request.getRemoteAddr() + "
"); out.println(""); out.println(""); } }
To invoke this servlet, issue URL http://localhost:8080/ws/servlet/EchoServlet
.
If Things Go Wrong...
- Check the error messages on the Tomcat's console (and use the error message to google for solution).
- Check the log files (at
"$CATALINA_HOME\logs
") - If the Tomcat console flashed and disappeared immediately, you can start the tomcat in the debugging mode by running "
catalina.bat debug
" and type "run
" in the "jdb
" prompt. Look out the error messages. - Check your Tomcat configuration files ("
server.xml
", "web.xml
", "content.xml
", etc.). I suggest that you revert back to the original configuration files to start Tomcat at port 8080. You may also modify the Tomcat startup scripts "startup.bat
" and "catalina.bat
" to display the error messages, by removing the command "echo off
".
Deploying Web Applications in Tomcat
This is the proper way of deploying web application (without using the evil Invoker Servlet):
Create a new Context (web application): Either
- (RECOMMENDED) Create a directory under
$CATALINA_HOME\webapps
and move your application codes under this directory. A context will be created automatically based on name of the directory. - Write a
<Context>
element in$CATALINA_HOME\conf\server.xml
, to specify the context's URL-Path and the document base directory. Refer to Step 3 above.
Create the directory structure for the new context:
- The directory that your application resides is called the context root or document base directory. You should keep all your HTML files and resources visible to the Internet users under the context root.
- Create a directory called "
WEB-INF
" under the context root. This directory, although under the context root, is not visible to the users. This is where you keep your application's configuration files such asweb.xml
. - Create a directory called "
classes
" under "WEB-INF
". This is where you keep all the Java classes such as servlets. - Create a dectory called "
lib
" under "WEB-INF
". This is where you keep the jar files and native libraries. - Optionally, create a directory called "
src
" under "WEB-INF
", for keeping the source files.
Write your Application's Web Configuration File called "web.xml
" and place it under your application's "WEB-INF
" directory.
The complete specification for "web.xml
" can be found in the "Java Servlet Specification" (@ http://java.sun.com/products/servlet), under "Deployment Descriptor".
Suppose that you wish to deploy two servlets: TestServlet.class
and QueryServlet.class
(that have to be kept under your application's "WEB-INF\classes
" directory):
<?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app> <servlet> <servlet-name>Test</servlet-name> <servlet-class>TestServlet</servlet-class> </servlet> <servlet> <servlet-name>Query</servlet-name> <servlet-class>QueryServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>Test</servlet-name> <url-pattern>/Echo</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Query</servlet-name> <url-pattern>/Query</url-pattern> </servlet-mapping> <session-config> <session-timeout>30</session-timeout>  </session-config> </web-app>
Explanation:
- Each servlet requires two configuration elements. A
<servlet>
to specify theservlet-name
and theservlet-class
, and a<servlet-mapping>
to specify the URL Path for that particularservlet-name
. In the above example, theTestServlet
can be referenced via URLhttp://host:port/context-path/Echo
, and theQueryServlet
via URLhttp://host:port/context-path/Query
. - You have to list ALL the
<servlet>
elements first, followed by<servlet-mapping>
elements.
Changing the default "webapps" directory
The default directory for deploying web applications is $CATALINA_HOME\webapps
. You could change the default by modifying the configuration file "conf\server.xml"
<host>
tag's "appBase
" attribute as follows:
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> ...... </host>
Directory Listing
Enable directory listing is handy for test server but not desire for production server. To enable directory listing for all the web applications, modify the $CATALINA_HOME\conf\web.xml
, by changing the "listings
" to "true
", as follows:
   <servlet> <servlet-name>default</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>  <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
Explanation: When a user reference the URL-path "/
" (i.e., http://host:port/context-path/
), the DefaultServlet
will be invoked to show the directory listing.
If you wish to allow directory listing of this web application only, you could disable the directory listing in "$CATALINA_HOME\conf\web.xml
" globally, and define the following <servlet>
and <servlet-mapping>
in your application's "WEB-INF\web.xml
", as follows. You need to use another servlet-name
for the DefaultServlet
.
<servlet> <servlet-name>DirectoryListing</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>true</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>DirectoryListing</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
Deploying a Web Application in a WAR file
You could use the JDK's jar
utiltiy to "zip" up all the files of a web application to produce a so-called WAR (Web Application Archive) file for deployment, or distribution.
.... Change current directory to the web application's context root > jar cvf test.war .
Drop the test.war
into $CATALINA_HOME\webapps
. A context called test
will be created automatically. You can access the web application via URL http://host:port/test
.
(Tomcat actually unpacks the test.war
into a test
directory in $CATALINA_HOME\webapps
.)
Automatic Servlet Reload
To enable automatic servlet reload, you need to specify <Context reloadable="true">...</Context>
(either in "$CATALINA_HOME\conf\context.xml
" or "$CATALINA_HOME\conf\server.xml
").
The following messages appear on the Tomcat's console if you re-compile your servlet:
XXX X, XXXX XX:XX:XX XX org.apache.catalina.core.StandardContext reload INFO: Reloading this Context has started
Tomcat's Startup Script
To start tomcat server, you could invoke the batch file "startup.bat
" (in directory "$CATALINA_HOME\bin
", where CATALINA_HOME
refers to the Tomcat installed directory). The "startup.bat
" invokes "catalina.bat start
".
Alternatively, you could call the "catalina.bat
" directly, which provides more options of starting Tomcat. Enter "catalina
" to view the options:
> catalina Using CATALINA_BASE: D:\bin\tomcat6.0.16 Using CATALINA_HOME: D:\bin\tomcat6.0.16 Using CATALINA_TMPDIR: D:\bin\tomcat6.0.16\temp Using JRE_HOME: d:\bin\jdk1.6 Usage: catalina ( commands ... ) commands: debug Start Catalina in a debugger debug -security Debug Catalina with a security manager jpda start Start Catalina under JPDA debugger run Start Catalina in the current window run -security Start in the current window with security manager start Start Catalina in a separate window start -security Start in a separate window with security manager stop Stop Catalina version What version of tomcat are you running?
Study the source codes of "Tomcat.bat
" and "catalina.bat
", if interested. Read "Command Shell - How to" about the syntax of batch files. At times, I need to use these files (comment-out the "ECHO OFF
") to debug Tomcat's startup problems.
Running Tomcat as a Windows Service
In a production environment, it is more convenient to run Tomcat as a "service", so that it can start automatically whenever the system is started (or re-start automatically after an unexpected interruption).
To install Tomcat as a service, start a CMD
shell (with administrator right) and run:
... Change directory to $CATALINA_HOME\bin ...
$CATALINA_HOME\bin> service install
Installing the service 'Tomcat6' ...
Using CATALINA_HOME: d:\tomcat-6.0.20
Using CATALINA_BASE: d:\tomcat-6.0.20
Using JAVA_HOME: d:\jdk1.6
Using JVM: d:\jdk1.6\jre\bin\server\jvm.dll
The service 'Tomcat6' has been installed.
The Tomcat service called "Apache Tomcat 6" is installed and will start automatically whenever the system is started. Check the "Services" under "Control Panel" ⇒ "Administrative Tools".
A GUI application called Tomcat6w
is available for monitoring and configuring Tomcat services. Read "Windows service HOW-TO" under the Tomcat documentation ($CATALINA_HOME\webapps\docs\windows-service-howto.html). Try running the Tomcat6w
.
$CATALINA_HOME\bin> tomcat6w
You could put the Tomcat icon in the system tray via the MS (Monitor Service) option:
$CATALINA_HOME\bin> tomcat6w //MS//
You can start/stop the Tomcat service now via (a) Tomcat6w
; (b) "Control Panel" ⇒ "Administrator Tools" ⇒ "Services" ⇒ "Apache Tomcat 6" ⇒ "Start"; or (c) issue the following command from a CMD
shell:
> net start tomcat6 The Apache Tomcat 6 service is starting.. The Apache Tomcat 6 service was started successfully. ...... ...... > net stop tomcat6 The Apache Tomcat 6 service is stopping.. The Apache Tomcat 6 service was stopped successfully.
To uninstall Tomcat Service, use Tomcat6w
or issue the following command:
$CATALINA_HOME\bin> service remove The service 'Tomcat6' has been removed
A flip side of running Tomcat as a service is you need to read the error messages from $CATALINA_HOME\logs
instead of the Tomcat console.

Using IParseHandlers along with dino.model property provides a clean way of validating request data. By the end of this guide, you will learn the best practices for handling parameter validations.
Using Parameter Validations
1. Create custom IParseHandlers
- It is recommended to set model.isValid to false when action parameters fails the validation.
- While adding values to model.values, we have to set the parameter key to differentiate with other action parameters.
- While adding validation errors to model.errors, we have to set the parameter key to differentiate with other action parameters.
- Always use .push for model.values and model.errors, because assigning values would override the object.
- Do no throw any exceptions while performing validations because it would not pass control back to controller.
2. Add IParseHandlers to Controller
From the above example, we have learned how to separate validation concerns from the controllers logic. Parameter validations provides an ability to reuse validation handlers with constructive errors displayed back to user.

The Internet is constantly being flooded with information about computer viruses and Trojans. However, interspersed among real virus notices are computer virus hoaxes. While these hoaxes do not infect systems, they are still time consuming and costly to handle. At CIAC, we find that we are spending much more time de-bunking hoaxes than handling real virus incidents. This page describes many of the hoax warnings that are found on the Internet today. We will also address some of the history of hoaxes on the Internet, how to identify a new hoax warning, how to identify a validated warning and what to do if you think a message is a hoax.

There are errors and the test cannot be displayed, open the test code editor to solve them.


const Xcomfort = require('xcomfort-shc-api');
This module lets you send commands from node.js to the Xcomfort smart home controller(SHC) made by Eaton. It has no affiliation with Eaton, and is used at your own risk.
If you have xcomfort and a smart home controller at home, this module can be used to create custom software for your system. For example you can create a webpage customized for your home that controls your lighting instead of that generic app that ships with the SHC
Import the module
const Xcomfort = require('xcomfort-shc-api');
First we need to create the config for the SHC
By default, the autoSetup parameter is set to true. When autoSetup is set to true, immediately when you create the instance, the module will do a login and then automatically fetch all your available devices and scenes and create internal lists with all information needed to send commands.
const config = {
baseUrl: 'http://<IP_ADDRESS>', // The url to reach the SHC on your network
username: 'user', // The username to login to the system
password: '1234' // The password for that user
autoSetup: true // Defaults to true.
}
We then create a new instance for this SHC.
const xapi = new Xcomfort(config);
The module extends nodes eventemitter, so we must listen for the ‘error’ event. If we don’t listen for this event, the app will crash whenever an error occures. Handle errors as you want.
xapi.on('error' (error) => {
console.log(error);
});
When autosetup is used, the module emits a ‘ready’ event we must wait for before we can start sending commands.
xapi.on('ready', () => {
changeLighting();
triggerSomeScene();
});
Lets send some commands to change light states. Say we have a light named “kitchen light” on the SHC. The module uses the same names as configured on the SHC. When you want confirmation, or something to happen after you have two choices. Either use a callback, or treat it as a promise. Both the callback and the resolved promise will return true if the change is confirmed from SHC, or it will be false if not.
const changeLighting = () => {
Apply a third argument with a callback function
xapi.setDimState('kitchen light', 30, (status) => {
if (status) {
console.log('Kitchen light dimmed to 30%');
}
})
If no callback the setDimState will return a promise.
xapi.setDimState('dining light', 'off')
.then((status) => {
if (status) {
console.log('Dining light turned off');
return xapi.setDimState('bathroom light', 'on');
}
})
.then((status) => {
if (status) {
console.log('Bathroom light turned on');
}
})
.catch((error) => {
console.log(error);
});
}
Trigger a scene called “All lights off” on the SHC
const triggerSomeScene = () => {
xapi.triggerScene('All lights off')
.then((status) => {
if (status) {
console.log('Scene triggered');
}
})
.catch((error) => {
console.log(error);
})
}

GOSPEL Matthew 13:24-30
A reading from the holy Gospel according to Matthew
At that time: Another parable Jesus put before the
crowds, saying, "The kingdom of heaven may be compared to a man who sowed
good seed in his field; but while men were sleeping, his enemy came and sowed
weeds among the wheat, and went away. So when the plants came up and bore
grain, then the weeds appeared also. And the servants of the householder came
and said to him, 'Sir, did you not sow good seed in your field? How then has it
weeds?' He said to them, 'An enemy has done this.' The servants said to him, 'Then
do you want us to go and gather them?' But he said, 'No; lest in gathering the
weeds you root up the wheat along with them. Let both grow together until the
harvest; and at harvest time I will tell the reapers, Gather the weeds first
and bind them in bundles to be burned, but gather the wheat into my barn.'"

DavarOCR: A Toolbox for OCR and Multi-Modal Document Understanding
Abstract
This paper presents DavarOCR, an open-source toolbox for OCR and document understanding tasks. DavarOCR currently implements 19 advanced algorithms, covering 9 different task forms. DavarOCR provides detailed usage instructions and the trained models for each algorithm. Compared with the previous opensource OCR toolbox, DavarOCR has relatively more complete support for the sub-tasks of the cutting-edge technology of document understanding. In order to promote the development and application of OCR technology in academia and industry, we pay more attention to the use of modules that different sub-domains of technology can share. DavarOCR is publicly released at https://github.com/hikopensource/Davar-Lab-OCR. [Paper]The work has obtained the Best Open Source Award in ACM MM 2022

etrepum commented on how hash functions need to be idempotent. I pretty much always interpret things about functions and idempotence incorrectly.
When used in computing, saying a function is idempotent generally means you can call it a hozillion times and the state of the system (& thus the return value of the function) will be the same as if you called it once.
When used in mathematics, a function f is idempotent if f(f(x)) = f(x) for all x. The computing quality of idempotence isn't useful since f(x) = f(x).
I would greatly appreciate it if we could all find a way to communicate that didn't involve language.
Actually, idempotency in the computing sense is only meaningful where there ARE side effects.
For a couple of pythonic examples: "a[b] = c" where a is a list IS idempotent. But "a.pop()" is not.
Since the last thing you want from a hash function is to mutate its argument, the only meaningful sense for "idempotent hash function" is the mathematical one.
And etrepum is confused.
Alex is right that this is the same as the mathematical definition if you view the state of the world as implicitly passed to and returned from every function you call.
I do use idempotent in computing in the mathy way, but maybe that is because I'm a math student.
Then the property f(f(x)) = f(x) seems like a desirable one if equality is replaced by some equivalence relation
This is still weaker than invariance of f though...
From now on I'll make it a point that "idempotent" DOES mean "f(f(x)) = f(x)".
I did not realize that people were using it with this other, incorrect meaning.
f(x)=f(x) is invariant, or referentially transparent, or side-effect free, whatever. Real idempotence is a useful property to be able to name in computing.
Join me and embrace the joy of self-righteousness!
I guess my point is that the clarity of the terms depends on the domain that you are speaking in.


In order for you to learn this course effectively, you will need to start thinking like a computer programmer. procedural thinking, abstract thinking, systems thinking, technological empathy and systems debugging are very important tools used by programmers.
There are three applications available for writing a code in this program: scratchpad, codepen and sublime. All of them can be used for the coding but they each have individual advantages and disadvantages over one another. Scratcpad is recommended for beginners
Basics of Web and HTML
Web was invented in the 1990's and it basically holds a colleccon of HTML documents. Web process has five or more major components which includes user, computer and Browser application, Internet and Server
HTML is the heart of Web, it's a basic language in which informations are entered on the web. It consists of text content, markups, references to other documents and links to other pages.
Texts: what you can see
Markup: what it looks like
Refrences: images and videos
Links: shortcut to other pages

I'm currently a Computer Programmer Analyst student at Conestoga College.
Previously i studied at Brock University for Business Administration but found it quite uninteresting, i then switched to the University of Guelph and finished a degree in Mathematical Economics there.
Although i enjoyed studying math, especially calculus and linear algebra, i didn't have very much interest in economics. After finishing that degree, i decided that i'd rather be a computer programmer so that i could utilize my mathematical skills and business knowledge in a more interesting way
All throughout my life i have been interested in digital technology. This interest led me to pursue learning the basics of coding on my own time. My hope is that my personal knowledge in computing, coupled with the formal education at Conestoga and my knowledge of the Business world will set me on a path towards creative success in the computer programming world.

The interfaces generated by DDV are constructed with multiscale images, HTML, JavaScript, and PHP. Generating interfaces with DDV requires a Windows operating system (7 or higher). The interfaces generated with DDV can be used on any web browser and operating system.
Visualizations generated with DDV can be placed on a web server. The following contains the links to examples of the visualizations generated by Tomasz Neugebauer, Éric Bordeleau, Vincent Burrus and Ryszard Brzezinski with this software: DNA Data Visualizations Generated with DDV Software. These examples include a number of bacteria chromosomes, as well as the entire Homo Sapiens genome.
The source code and image data for these generated examples is also available as a dataset at Zenodo (http://dx.doi.org/10.5281/zenodo.33608)
The source code for this application is available at Github.


Summary: A Villain from the distant future travels 100 years back in time to escape and kidnaps a Billionaire and demands a 50 Billion Dollar Ransom for his release. However, when he receives the money, he does not release him and taunts to kill him for more money until he gets all of his money and becomes the richest man in the world. The Billionaire pleads for mercy but the Villain takes no notice of him. Suddenly, the Hero arrives and rescues him, taking the villain’s blaster. When the villain runs after him, the hero shoots him.
