3D Graphics – History and Beyond


Graphics is a field of computer science in which the research has started but it hasn’t yet been explored to such an extent. The 3D graphics are the updated version of the graphics where the representation of the data is in three dimensional. If we are to compare the 2D and the 3D graphics there are many ways in which they are similar. The algorithms that are used by 3D graphics and the rendering techniques used are adopted from 2D. The lightning techniques that are used in the 3D are used to enhance the 2D graphics as well. The line between 2D and 3D thus is quite thin and often makes the differences blurry.

20th century:

The incredibly early form of graphics in computer systems was proposed by an MIT student in the 1960s. He put forward an application where shapes could be formed with options of storage so that the data could be used for later use. A breakthrough came in the graphics in the 1970s. This was the golden period when the microprocessor emerged. During this time the images could be scanned and then that piece of data could be manipulated in limited yet interesting ways. The concept of curved and motion pictures was made known by this time. This period brought the idea of 3D graphics lighter. The Mackintosh was already in the market which had a GUI (Graphical User Interface). A high-quality program, named TOPAS, enabling animation was making its way into the market. Another software supporting 3D named as “Vol Libre” was introduced in the 1980s which meant a full flash 3D graphic system wasn’t much far. In 1990s a new jump was made to the photo-realistic animation which was the basis for the creation of a complete animated movie for computers. This was a real step forward since now slow-motion and other features were being used effectively.

With all the little accomplishments there always was a little something that didn’t add up quite well and the output wasn’t the one that could change the course of computer graphics. This issue was resolved in the 2000s when the focus became to produce content that was believable. The concept of color images became better known and many companies start investing in the business relating to the 3D Graphics.

21st century:

increased developments have been made in this domain. The success is in front of us in the form of the high-quality image outputs. The images in this era has state of the art digital effects which are completely believable. The time in which these images are created and the efficiency with which these can be manipulated is uncanny. The development has reached a point where automated games in HD are produced and are being manipulated by the user at run time providing excellent quality.

As an enthusiast you will agree that the domain of graphics has come a long way yet there is a lot that can be further achieved and with the right resources it doesn’t seem difficult.

The whitepaper will take you to the new features of the platform and add you to the freelancing world. We will also investigate Initial Coin Offering (ICO) with details and delve deep into the ideas for the future of Blocklancer ecosystem as well as the platform.

This platform is intended to bring the revolution in the process of freelancing and improve the corporation between client and freelancers. It will go to solve many problems involved in the freelancing process including:

  • Fake reviews
  • Refusal of Payment
  • Abuse of power by specific authority figures

We passionately believe that completely self-regulatory system is the best option for freelancer’s platform like Blocklancer. So, we have developed a new form of job market called “DAJ” or “Distributed Autonomous Job market.”

DAJ is our vision of the future labor market and our proposed solution for many of underlying problems currently facing freelancing platforms, and most of the decisions were made on our platform is in the hands of Token Holders.


Freelancers or clients can rank on a scale from 1 to 5 stars. They may also choose to add a written review, which is optional. Each user has a summary estimate that is always displayed along with the username. Freelancers also have a separate rating for each skill that allows a potential client to determine the capabilities of the freelancers in question, which makes the process of finding the right freelancer much easier

Action in Job

Both freelancers and customers can perform specific operations in a job. To make this section clearer, we share the measures in freelance and client actions.

Problem in Industry

We are now discussing the most pressing concerns. Freelancers face the current market and freelance platforms or sites offering jobs. An overview of the issues will be described below:

  1. Unnecessarily difficult to get paid from Clients
  2. Customers submit missing/negative profile reviews
  3. High fees on existing freelancing platforms
  4. Unlimited central power on existing freelancing platforms

System Architecture

Blocklancer is the first decentralized and serverless labor market. We accomplish this by combining existing technologies such as Ethereal and IPFS. As Blockchain technology is still in the architecture building phase, we also implement our own, own solutions.

Core Architecture

Blocklancer consists of three main components:

1.) Ethereum: Ethereum is the backbone of the Blocklancer. The smart contracts are implemented for Ethereum in Soliditet’s programming language. Ethereum is needed as the distributed master book in Blocklancer, which allows society to verify transactions within the ecosystem.

2.) Interplanetary File System IPFS: IPFS allows distributed storage of files. Because it is too expensive to store all data in the Ethereum Blockchain, the bulk of Lean IT in IT industry.

3.) Database: Because we want to provide a good user experience, it must be swift to search for jobs. One major issue with Blockchain technology is that it is too slow and expensive to ask the data. Therefore, it is necessary to save somehow data in a database that is searchable. Some of the funds collected through Blocklancer ICO will be used to develop or collaborate with other projects that are already promoting this solution.

Blocklancer currently has collaboration in this area with Ties Network. The partnership creates significant synergies with the decentralized autonomous business model Blocklancer is based on and enables far greater scalability.

3 Essential Open Source Tools for Web Designers

Web development is one entirely different world if you ask me it is the art of the Computer world. You can create something entirely new every time, and it can be awe-worthy. The priority of web designers is to find an open source tool which makes the working comfortable, and they don’t go into the loss of trying new things. I would love to know the favorite tools of the web designers are reading this post. I am going to let you know about the three essential open source tools for web designers:


If you have ever had the misfortune (kidding) of going through a designer’s computer, I can almost guarantee you will find this software on their desktop. Why? Well, it is the very start of every designer’s life, and some even continue to use it no matter how far along they have come. It is an open source tool that allows you to set up local Web Server. It is for the testing of all that what you are creating before you buy, a domain. Xampp is the abbreviation for X-Cross Platform, Apache, MariaDB, PHP, and Perl. With one installation you can access all, of these. It installs and configures each of the above, and the entire library of each can use. It is the favorite tool for many web designers. I made my first local page on this and to be very honest it was awesome. Previously there was MySQL used as a database language, but with innovative technology, the No SQL based MariaDB is preferred. If you ought to build a website, I will recommend you start with downloading Xampp.


Now if you overthink, by any chance, haven’t heard about this. It is just an upgraded version of AWS history we all have in our PCs. It is the open source editor which lets you write the actual code for your website. Why go for this? You aren’t stuck with this. It isn’t the only option you can go for. There are several others but why I am talking about this? It is my favorite editor. However, apart from playing favorites, it has multiple advantages. It provides syntax highlighting. If you are a professional or even know a little bit about programming, you must know how important this is. You could get lost in the code if this wasn’t there. It is such a lifesaver. Plus, I do love the colors it gives to the normal code. It provides code folding and tabbed editing for more than 50 languages (scripting, programming, and markup). The support and feedback system for this software is vast, and in case of any issue, things can be resolved a lot quicker.


You have the editor, and the server all you needed was an excellent choice for the framework. Node.js is exactly that. It is a JavaScript-based framework used to produce a responsive page. This allows you to create dynamic web pages. The reason it prefers over other structure is that it is an event-driven, i.e., asynchronous in nature. This means that it interacts with the OS and makes the working a lot faster.

Now that you know the essential tool that is open source you can begin your web designing experience. If you take the right instructions, you can get amazing results.

Vanuzealan Petro Cryptocurrency

Vanuzealan Petro Cryptocurrency is one of the many forms of digital currency. Cryptocurrencies have been previously predicted to replace the local currencies due to their increasing value. Such a situation has currently observed in Venezuela. The provincial government has introduced it as an alternative to the local Boliver Fuerte currency since the country’s economy is shaking down to destruction.  Where some of the government officials and locals are seen in favor of this initiative, the opposition is highly about it as an illegal form of money and a secure framework for corruption. Getting all these associated factors straight is one way of achieving an understanding of this cryptocurrency:

Current situation of Venezuela

Venezuela is a land of oil and mineral reservoirs. Over 50 percent of the total GDP of the country depends upon oil exchange and selling to the foreign countries. Venezuela once was one of the Top 5 wealthiest states in the 1950’s when it came to per capita income. However, after the reign of Hugo Chavez, the country has gone into a significant state debt. This has resulted in a sky-rocketing increase in inflation. The current President Madura has held on to Chavez’s policies resulting in worsening of the situation. Now, the country’s local currency, Boliver Fuerte, is worth nothing and trading through it results in more loss than benefit.

Petro crypto-currency worth

Vanuzealan Petro Cryptocurrency has opened new financial avenues in the international market. Attracting some investors from Saudi Arabia, Turkey, UAE, etc., has helped in stabilizing the country’s economic and social situation. Initially created to prevent and overcome US and EU sanctions, Petro has helped the country with a total of $735 million within 24 hours of the February pre-sale. One petro token, labeled as PTR equals a cost of one oil barrel as oil reserves back this currency. The approx. amount then comes out as 1PTR equals 60 dollars. Government is also offering subsidies on electricity bills and discounts on other goods and services.

Petro crypto-currency mining

The mining of petro is done via pre-mining sessions. Just recently 100 million Petro tokens were released. Presale took the 38.4 percent, 44 percent of petro was available on the crowd-sale. The remaining 17.6 percent has reserved the Superintendent of VIBE. VIBE is a land destination for institutional, political and legal matters.

Petro cryptocurrency VS Other cryptocurrencies

Unlike the Bitcoin mining, in which Bitcoin considered as an asset and not a convertible currency, Vanuzealan Petro Cryptocurrency is a replaceable and interchangeable currency with value. It has been expected to have a token with the name of ERC20 which will become a part of Ethereum blockchain.

Doubts and fears

Despite the increasing popularity of the Petro, some oppositional organizations have called it Government’s way of hiding the stolen money. The opposition also thinks that it is an illegal way of earning money and that every investor will regret investing in it. Also, the business-men are not sure whether to settle for Petro or not yet.

Vanuzealan Petro Cryptocurrency is a gateway to future money-innovation if it works as expected. The mining is currently under process. What can be done to reinforce new technology? Oracle Database is a great way to start as it lowers costs and maintain IT security.


SQL is a Standard Programming Language for retrieving and manipulating the relational database. It stands for Structured Query Language and sometimes pronounced as “See-Quel.” It used for managing data held in the Microsoft SQL Server, IBM DB2, Oracle, MySQL, Relational Database Management System (RDBMS) and Microsoft Access.

SQL has two advantages over the old APIs like ISAM or VSAM. First, you can easily access many records by a single command, and second, it has dropped the need to stipulate how to reach a file with or without an index.

In 1986 and 1987, SQL became a standard of the American National Standards Institute (ANSI), and of the International Organization for Standardization (ISO).

Although SQL became standard of ANSI/ISO, yet different versions of the SQL language are available. For example, a set of extensions offered by Microsoft called Transact-SQL (T-SQL), while PL/SQL is Oracle’s extended version. Though, they all support at least the main commands (such as SELECT, UPDATE, DELETE, INSERT, WHERE) in the same way.

What can SQL Do?

  • SQL can execute queries against a database.
  • SQL can insert, change or update records in a database.
  • SQL can remove or retrieve records from a database.
  • SQL can create new databases or can add a new table in an existing
  • SQL can create stored procedures and opinions in a database.
  • SQL can set permissions on tables, procedures, and views.


SQL uses specific commands to carry out the required tasks those guidelines are mainly characterized into four classes as explained under:

DDL (Data Definition Language):

DDL or Data Definition Language consists of the SQL commands that deal with descriptions of the database schema and is used to create and change the structure of the database.

  • CREATE is used to create the database or its objects.
  • DROPis used to remove objects from the database.
  • ALTER is used to change the structure of the database.
  • TRUNCAT is used to remove all records from a table.
  • COMMENT is used to add comments in the data dictionary.
  • RENAME is used to rename objects in the database.

TCL (Transaction Control Language):

TCL instructions deal with any transaction within the database.

  • COMMIT commits a Transaction.
  • ROLLBACK rollbacks a transaction in case of an error occurs.
  • SAVEPOINT sets a savepoint within a transaction.
  • SET TRANSACTION specifies characteristics for the transaction.

DML (Data Manipulation Language):

These commands deal with the manipulation of data present in the database.

  • SELECTis used to retrieve data from the
  • INSERT is used to enter data into a table.
  • UPDATEis used to update existing data within a table.
  • DELETEis used to remove records from a database table.

DCL (Data Control Language):

DCL includes commands deals with the rights, permissions and other controls of the database system.

  • GRANT gives user access privileges to the database.
  • REVOKE withdraw user access privileges.

Wireless Security

Wireless Internet technology is increasingly deployed in offices, public environments, and as well as by the internet users at home. Due to this rapid growth of the internet, its security compromised. When wireless technology was first introduced, there were relatively few dangers. It was difficult for the hackers to get hands on the new technology because it was not common yet. However, Our current wireless protocols and encryption methods have associated with many security risks. Security can also compromise because of carelessness and ignorance at the user and IT level.

Hacking methods have become much more classy and innovative with wireless access. Hackers have found wireless network easy to break into as compared to a wired network. They can easily hack into our systems through any loop in network security. Thus there is a need for some security parameters to keep the networks secure.

What is Wireless security?

Wireless security is the process of preventing a network from unauthorized access by designing, implementing and ensuring safety over a system. Windows security is just an aspect of computer security; however, organizations are more vulnerable to security breaches.

The most common types of security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WAP). WEP is a weak security protocol. Its password can easily crack within minutes through a basic laptop and readily available tools. In 2003, Wi-Fi Protected Access (WAP) replaced it, and it was a quick alternative to improve the network security.

Threats to Wireless Network:

There are some threats exists to the Wireless networks. Used methods have briefly discussed below:

Denial of Service:

In DOS attack the hacker continuously bombards the system with bogus requests or rare traffic. This cause the user to not be able to access the network and may even cause the network to crash.

Passive Capturing:

Passive capturing is performed by merely getting within the range of network and then obtaining data. This information can be used to break-in or spoof in the organization.

Man, in the middle attack:

In a man in the middle attack, the attacker places him between two devices often a web browser and web server and then intercepts or change the communication.

Network Injection:

In this method, the hacker injects bogus re-configuration commands that can affect routers, intelligent hubs, and switches. A whole network can be brought down using this method and then it will require rebooting or even reprogramming of router.

Security Measures:

There is a range of Wireless security measures that can prevent your network from any unauthorized access. Some of them are:

SSID Hiding:

A simple way to protect your system is to hide your SSID unless you need to give access to someone.

MAC ID Filtering:

A simple and effective way is to allow only authorized MAC address to connect to your network. This will prevent unauthorized mac addresses to connect to your system.

End to End Encryption:

To keep your network safe, the application layer of the system should be encrypted and authorized using technologies like SSL, SSH, and PGP, etc.

Static IP Address:

WAP provides IP addresses to clients via DHCP. If the clients set their IP addresses, then it is more difficult for an intruder to log onto the network. It supplies little protection against an attacker.
