A Technical term to explain Tremendous Volumes of Data stored that becomes complicated and sophisticated to visualize, share, search, analyze or transfer Data using Traditional Application means or even on-hand Database Management Applications but can only be handled be Extremely-fast Paralleled Software Applications running on many Massively High-speed Servers.Finally, Big Data somehow explains or theorizes the future of Internet and major firms that handle massive amounts of Information or Data daily.
GIS, Geographical Information System is an Integration of systems designed to capture/collect, store, manipulate, analyze, manage, and display all types of geographical data such as Geo-spatial data.
GeoJSON ;-
An open format for encoding a collection of geographic data structures and more compact data structure to store geographical co-ordinates, that is, Spatial data format types supported in GeoJSON include points, polygons,
multi-polygons, features, geometry collections, and bounding boxes,
which are stored along with feature information and attributes. It borrows format from JavaScript's JSON(JavaScript Object Notation).
PostGIS ; -
An open source software that adds support for geographic objects to the PostgreSQL database and just like GeoJSON, PostGIS follows the simple features for SQL specification from the Open Geospatial Consortium (OGC).
CartoDB ;-
A Geospatial database used to create data driven maps, or dynamic maps, analyze and build location aware
and geospatial applications with your data using the power using the
power of PostGIS.
Hacker
A person who intents or seeks to intrude into the system without owner's consent through the network or system thus exploiting the weaknesses of the system or network. Hackers aim more at security breaches to infiltrate to owner's system or network and one of the most malicious types hackers are Black Hats, but contrasts the ethical hackers, that is, White Hats. They use sophisticated hack tools probably made by them or other people, or malicious software applications, e.g., Rootkit, Backdoor, Trojan horse, Virus, Worm, Spyware, Botnet, Keystroke logging, Antivirus software,Firewall, IDS(Intrusion Detection Systems).
Classifications of hackers ; -
- White hat
- Black hat
- Grey hat
- Elite hacker
- Script kiddie
- Neophyte
- Blue hat
- Hacktivist
- Nation state
- Organized criminal gangs
- Bots
Ways you can use to intrude into a system; -
- SQL(Structured Query Language) injection.
Hiding code snippets inside a page request to a web server, especially SQL commands which compromise the security of the website or server. Mostly, PHP or any other suitable scripting languages would be suitable to be deployed in such a scenario. This is mostly for any scripting languages that run on the web server using SQL such as PHP.
- XSS(Cross-Site Scripting).
This would be the accessing information of web pages using scripts that access the data(variables) exposed when the web page is running on the client-side. Mostly, Javascript language may be deployed for such a scenario because it runs best on client machines. This is mostly for Javascript Hackers.
Mostly deployed any where you have software programming is involved especially the desktop software applications which involve very fast vigorous processes that may compromise data as well. This kind of computing may be very malicious when well-used on an attack of a system. Learned in advanced Computer science courses and examples of brute-force techniques are recursion and iteration.
Cloud Computing "C2" ;-
Cloud Architecture or Engineering which is popularly known to be Cloud Computing is majorly embraced by today's large Enterprises like Google, Amazon(EC2), Stackato, HP(which stepped up recently) and others. Cloud Computing which involves the use of Networked Computing Resources that are delivered or accessed as a service over a network, mostly a large and extensive network especially the Internet. The Cloud Computing has some features like Autonomic Computing, P2P Computing, Utility Computing, Client-Server Model, Extremely High-Processing Power Computers e.g., Mainframe Computers, Grid Computing. The "Cloud" name comes from the Highly Complex Architecture employed on the Servers that enables a variety of devices to use the Cloud Services that are usually abbreviated with an "aaS".
- Infrastructure as a service (IaaS)
- Platform as a service (PaaS)
- Software as a service (SaaS)
- Network as a service (NaaS)
- Storage as a service (STaaS)
- Security as a service (SECaaS)
- Database as a service (DBaaS)
- Test environment as a service (TEaaS)
- API as a service (APIaaS)
- Backend as a service (BaaS)
PHP acronym meaning Personal Home Page Tools changed to PHP: Hypertext Preprocessor in 1997, it was designed by Rasmus Lerdorf using C programming language in 1995. PHP is a more of a server-side scripting language than programming language because of it's weakly typed syntax and limited capabilities to system resources, designed for web development to develop web portals, applications and CMS(Content Management System). It has evolved over the years now has a CLI(Command Line Interface) and GUI-based capability to produce stand-alone GUI applications. Major softwares designed using PHP include Content Management Systems like, Joomla, Drupal, Wordpress, WikiMedia, etc. Current version of PHP is PHP 5.5.0 alpha released on November 2012, of which PHP 6 is yet to be released probably next year which is not known.
Java Standard Edition acts as a core of Java's other editions, that is, Java EE, Java ME, Java FX, Java Card and PersonalJava. Java Enterprise Edition was added to give Java Technology an extended capability of distributed and multi-tier architectures, and web services that provides an extensive API to develop an enterprise applications, Large-scale software that includes network and web services that are robust, reliable, scalable, flexible, and highly secure to the desired industry standards. The Java EE platform has evolved over the years, currently known as Java EE 6(Java Enterprise Edition 6), Java EE 7 is the latest release.
- J2EE 1.2(Dec 12, 1999)
- J2EE 1.3(Sep 24, 2001)
- J2EE 1.4(Nov 11, 2003)
- Java EE 5(May 11, 2006)
- Java EE 6(Dec 10, 2009)
- Java EE 7(May 28, 2013) under JSR 342
There are many application servers that support and can run Java Web or Enterprise Applications, but the preferred and recommended application server would be Glassfish Server Open Source Edition, current version v3. Java EE 6 is rich full of libraries and frameworks that has proved development to be quite of high complexities and this has been quite challenging for junior developers like me. I didn't mention about java-based build tool Ant which is proved to be very important for Web or Enterprise Application development. Java EE 6 which is multi-tier has the Client-tier(runs on Client's machine), Web-tier(runs on Web Server), Bussiness-tier(runs on Web Server), and the Enterprise-tier(runs on Database Server).
An example of a Hello World GUI snippet using Python programming language;-
#! /usr/local/bin/python
from Tkinter import *
root = Tk()
w = Label(root, text="Hello, World!\n")
w.pack()
root.mainloop()
