All About Data Scientist

These days business houses are stockpiling a huge amount of data which is often considered as the precious asset for the companies. It is surprising to know that more than 90% of the data which is available in nowadays has been generated in the last two years. In earlier days, due to the scant knowledge, the companies didn’t know how to extract the meaningful and relevant information from this stored data. But the advent of data analytics has successfully bridged the gap between the company and this unpolished data.

So, it can be concluded that the data analytics has completely changed the vision of the companies and by using the comprehensive business analytics, the companies can take the right decisions which will help them to surpass their contenders. Hence, the organizations are accentuating on data analysis which is extracted from raw data by specialized computer programs and are cultivating their employees regarding how to accustom and publicize the information that they are getting from these organized data.

Since the importance of data analytics is burgeoning day by day, hence the companies are appointing the sagacious professionals who will provide the company with the wider insights of the structured data. A data scientist will be responsible for designing and implementing various processes and different layouts for the intricate and large-scale datasets that are basically used for modelling, data mining, and various research purposes.

What are the core responsibilities of a data scientist? Why they became an integral part of every business?

Need to take care of those data which affect the organization most: A data scientist’s core job is to identify the most relevant data which will help the organization to make the right decisions so that they can proliferate their business and growth. A data scientist usually dives into the pool of data and with his expertise and knowledge, he used to find all the imperative information and ignores other irrelevant data so that the company can take the apt decisions quickly. Suppose a company deals with mobile phones, then they should try to find out who are using their phones currently? How can they find more users like them? Only a pedantic data scientist can answer these questions and hence, the companies are employing more data scientists into their core team.

Need to present data in such a way that anyone can understand it: Though a data scientist should be well-equipped with all the technical and machine languages like R, Python, etc., but he should present the data in a facile and simpler way so that even a layman can understand the insight from the data. A data scientist should never show a regression analysis or a plot from R because only a few people have an adequate knowledge regarding these. Rather he should present the data in a story telling way which consists of simple slides and visuals instead of numbers. Visualizing and communicating data are equally important, specially for the nascent companies who are making the data-driven decisions for the first time or the companies where these professionals are viewed as people who help others making data-oriented decisions. In this way, everyone in a company should understand which portions or departments of the company need further improvement.

Help in the promotions and other marketing strategies: A data scientist will also work coherently with the marketing team and helps the company to conduct the fruitful campaigns and promotions which will certainly enhance the sales and profit. If a mobile company has an idea who are their most engaged customers, then a data scientist will help the company to see what campaigns those members liked the most or what made them get involved so closely with the brand? By evaluating all these questions, a company can design their promotional campaigns and other marketing strategies in such a way which will help them in enhancing their customer base and visibility.

It would be an arduous job to describe what are the prime job roles of a data scientist within a few words. Apart from having a proficient knowledge of technical, a data scientist should know how to create directives from the data, and how to present the data in a story telling way. Nowadays, along with the marketing and production or service teams, these professionals are also the pillars of the company for its growth. Hence, the companies are commissioning more data scientists into its team so that it can go beyond its competitors.

Understanding Network Security

Transfer of data in a business system often takes place with the help of the digital medium. In such a scenario security of this data remains at the prime focus of all the organizations. Cryptography here plays a pivotal role in maintaining the safety of the transferred data. Let us explore the in and out of this technique of core importance.

What is cryptography?
Cryptography is the method to hide the information with the use of microdots, image-word merging, or with some other ways. In technical arena, it can be termed as scrambling plain text into an encrypted form, usually called Ciphertext, then again to convert it into decrypted format known as Cleartext. This process of encoding and decoding is called cryptography and people practicing this field are known as cryptographers.

What are the Objectives of Cryptography?

Modern cryptography follows the below objectives-
1. Confidentiality- anyone who is out of the circle cannot understand the information between the sender and receiver.
2. Integrity- no alteration is possible once the message is released.
3. Authentication- information, and sources in the cryptography system are purely authentic. Both sender and receiver can identify each other and origin or destination of the information.
4. Non-repudiation- none of the sender or receivers can step back of the message at a later stage.
5. Access control- only authorized people can access the confidential data.

To fulfill the above objectives the following formats of cryptography are practiced-

1. Symmetric cryptography- also known as secret key cryptography, it is a method in which both sender and receiver share the same secret code and key for encryption and decryption. This technique is useful if you are communicating with a limited number of people, however, it is not much useful for mass communication.
2. Asymmetric cryptography- this is also known as public key cryptography in which, separate keys are used for encryption and decryption. This is useful for key exchange and digital signatures such as RSA, digital signature algorithm, public-key cryptography standard etc.
3. Message-digest- in this, a hash function is used to permanently encrypt the data. This is also called one-way encryption.

Cryptography protects the network resources against alteration, destruction, and their unauthorized use. They secure the network system, IT assets, and the confidential data. In today’s scenario, it has become quite easy to alter or restrain the data and information. Theft of confidential information is again a discomforting phenomenon.

Tips To Keep Your Batteries

If you have rechargeable batteries, it’s your responsibility to take good care of them, for them to give you a long service. The cool thing is that there are plenty of things you can do to make it possible. Some of the things you can do include:

Tips on how to maintain your batteries

There are plenty of stuff you should do. When making the purchase always remember that a rechargeable battery is as good as its charger; therefore, you should never fast charge it. When you charge your battery too fast, you put it at the risk of overheating which puts it in great danger of getting damaged.

Just as you should never fast charge the units, you also should never over discharge them. To be on the safe side, wait until they show the low battery signal. Don’t wait until the charge is completely gone as it will destroy the battery.

You should be cautious of how you use the batteries. As rule of thumb, you should never mix different batteries. The best way of going about it is using batteries of the same capacity, brand, and chemistry. You also should never mix rechargeable and non-rechargeable batteries as they have different voltages. This results in them damaging each other.

You should be cautious of how you charge the units. When it comes to the chargers, go for high-quality chargers that won’t overcharge the units. For a great experience, work with high-quality smart chargers. You should regularly check the charging of the batteries to avoid charging them beyond the rated capacity. Some people make the mistake of leaving the batteries in the chargers for more than 24 hours. This shouldn’t be you.

In the bid of maintaining the units in great shape, you should avoid using ultra-fast chargers. Keep off chargers offering 1-hour charge. In most cases, the fast chargers charge the batteries up to 70%. They don’t charge it up to 100%.

Once every few months, you should discharge your battery fully and recharge it. This is to prevent the battery from forming crystals resulting to damage to the battery. You also should regularly use the batteries. You should note that when you don’t use the units for long, crystals begin to form.


These are tips on how to maintain your rechargeable batteries in good shape. To increase the chances of the units lasting for a long time, always invest in high-quality units.

Why You Need Barcodes

When it comes to saving cost and time, barcodes play a great role. Unfortunately, they are not being used to save costs in the here and now. The fact of the matter is that these tools are a great way of helping businesses improve efficiency and cut down on overhead. In other words, barcodes are both reliable and cost-effective.

Human error

With barcodes, the chances of human error are reduced. Entering data manually increase the chances of error since humans type the information. On the other hand, barcodes are a lot more efficient. Scanning a barcode takes less time than typing the data manually.

Training time

A barcode system helps businesses reduce the time spent on training employees. You need a couple of minutes to learn to use the barcode scanner. Aside from this, employees don’t necessary have to be familiar with the pricing or inventory procedure. As a result, businesses don’t have to spend an arm and a leg on employee training.

Designing and printing

As far as designing and printing goes, barcodes don’t cost a lot. Typically, they don’t cost a lot of money if you want to customize them based on a lot of materials and finishes.


As far as versatility goes, barcodes are on top of the list. So, they can be used for all types of data collection, which includes inventory and pricing information as well. Apart from this, since barcodes can be used on any product, they can be used for tracking products, equipment and outgoing shipments as well.

Inventory control

Barcodes offer better inventory control. Since these tools help you track inventory in an efficient manner, you can reduce the inventory levels. How does it benefit you? Actually, reducing the inventory levels may help you reduce overhead. Moreover, it’s also possible to track the equipment location, reduce the time invested in looking for or replacing the equipment.

Better data

Another great advantage of using barcodes is that they offer better data. The reason is that a single barcode is enough for pricing and inventory information. The access to both data sources is quick. Apart from this, they can be modified to include other related information based on the needs. They offer data that is reliable and can be used in various ways.

Rapid availability

Information and data obtained via a barcode is easily available. The information is stored into a computer after scanning, which makes the availability a lot faster. The turnaround time makes sure that data recording or retrieval won’t cost a lot of time.

Decision making

For decision making, we suggest that you use barcodes. The reason is that data is obtained in an efficient manner, which helps you make informed decisions. At the end, it saves you a lot of time and money.

Long story short, barcodes are user-friendly and don’t cost a lot of money. As a matter of fact, these tools are a great tool to help you track, price, data and inventory in an efficient manner. Finally, the goal of a barcode system is to cut down on the overhead.
