Tips for becoming an ethical hacker

With the advancement in information technology, people are increasingly becoming busy. Some people have evolved drastically due to technological improvement. This has made the information technology more vulnerable to hacking. Important data and information can be now accessed by hackers who modify, destroy or steal it. This has greatly affected the information system’s credibility. They can easily breach and combat the enabled security system in devices leaving the owners mugged.

This calls for increased security in the information sector to prevent these situations from occurring. Ethical hackers are professionals who are skilled to safeguard the security and safety of your information and data from any catastrophe. The following are some of the important points that the professional ethical hackers need to understand.

Know the different kinds of hacking

The different types of hacking include non-ethical hacking, Grey Hat, and White Hat hacking. Professional hackers are required to evaluate these types and understand them well. A deep knowledge is helpful in combating unauthorized access or breaching of the information systems.

Know the basic requirements

Every professional hacker is supposed to identify all the basic requirements. This is the main reason why these individuals are required to undertake a professional course and get licensed.

Running your brain’s horses

After evaluating the basic requirements, a professional hacker is expected to run his brain’s horses. This will help you in identifying which are you are good at. Do you love working in software or hardware securities? Information security is one of the vast fields that require one to specialize in a specific area. You should always master one formula before going to another one. Be careful when choosing.

Make use of the UNIX OS

Along with other certificate or diploma programs, you are advised to make maximum use of this operating system. UNIX OS is essential when it comes to hacking. Hackers originally developed UNIX operating system. All the ethical hackers to understand it well.


Knowing your weakness and strength

This can be done by implementing the acquired knowledge. Doing things practically on the information system will show whether an ethical hacker has already mastered the necessary tricks. You should proceed to the next round once you have completed writing down a detailed analysis of the first part.

Identifying your program’s commercial aspect

This will involve looking for lucrative jobs or positions in the market. There are many job opportunities in both the government and private sector. Alternatively, you can start your own business where you offer services to different customers or organizations.



Important features of a 3D Pen

The 3D pen is one of the emerging technologies. These pens are very interesting, and they can greatly help you. With this technology, one can easily make a model of car or any other object. There are many types of 3D pens in the current market. The following are some of the useful features that you need to consider when purchasing a 3D pen.

Required temperatures

Its performance is mainly determined by the environmental temperature. . It is therefore important to read the reviews and description of how these pens perform in different temperatures. This will enable you to understand your working environment. A pen might not perform well in a humid or hot environment.

Compatible features

The working principle of a 3D pen is very simple. These pens use plastic to “write” instead of ink. Furthermore, a good pen can work on different types of surfaces. You should avoid buying those pens that work on specific surfaces. A good pen should be convenient when it comes to usage.

Timing of the shell’s plastic

This is the plastic inside the pen’s shell. After heating, this plastic should come out without causing any interruption. Applying immense heat can make your plastic to become very sticky. This should be avoided as it can make your colours to look slightly different.

Cooling time

The 3D pen technology relies on the heat. Heat must be applied for a 3D pen to work efficiently. The plastic contained in 3 D pen should heat up first for the pen to doodle or draw. After heating, this pen should be given time for it to cool down. The cooling of the pen is done under controlled conditions. The cooling time should not be too high. Enough gap is needed between the cooling down and heating up of a 3D pen.


Most of the manufactures will offer a warranty. However, the warranty offered will depend on the manufacturer. Some opt to repair your pen when it has a problem while others will replace it. You should always go for the product that has the right warranty.

Clogging issues

Clogging of the plastic after the cooling process can make your plastic to get stuck in your containers. You are advised to replace your plastic if it happens to get clogged after use even if this might cost you an extra amount of money. A good 3D pen has its clogging system that prevents the clogging of plastic.


Linked Heritage is a 30 month EU project, started on 1st April 2011.

The main goals are to contribute large quantities of new content to Europeana, from both the public and private sectors; to demonstrate enhancement of quality of content, in terms of metadata richness, re-use potential and uniqueness; to demonstrate enable improved search, retrieval and use of Europeana content.

The consortium includes representatives of all the key stakeholder groups from 20 EU countries, together
with Israel and Russia. These include ministries and responsible government agencies, content providers and
aggregators, leading research centres, publishers and SMEs.

Your terminology as a part of the semantic webrecommendations for design and management (PDF, 2.5MB)


This publication, edited by Linked Heritage WP3 and ATHENA WP4 “Terminology and multilingualism”, aims in priority at people working in European museums, experts or non-experts in Information Engineering and/or Linguistics, who have an interest on terminology and multilingualism. It proposes recommendations helping you to manage your terminology, to make it compliant and optimized for improving multilinguality on Europeana and to make it as a part of the Semantic Web following. The more you respect them, the more you improve the future retrievability of your digital collections online.

Video on Europeana API
The Europeana API allows you to build applications of your own, from a customised view of the Europeana content on your websites (for instance, how much information to be shown, where, and in what format) to creative mash-ups and new services such as an iPhone app. More

Europeana API 2.0
The preview launch of the new Europeana API has just happened. The API is based on Europeana’s new metadata schema, the Europeana Data Model. The previous version was based on Europeana Semantic Elements, which is an extended Dublin Core schema. This new schema separates different entities, and is close to some semantic principles.More
