Tips To Buy Power Bank

There are many names that can be used to refer to a portable battery and they include power backup, pocket power cells, fuel banks, portable chargers, battery packs and so on. Regardless of what you decide to call them, they are still the same thing. The aim is to charge the tablet or phone without necessarily having a power outlet.

They come in all sizes. There are smaller sizes that are ideal for the smartphones and the bigger sizes that can cater multiple charges and are ideal for charging your tablet.

There are some that have cables while yet others include multiple ports to allow you to charge multiple devices at the same time.

For smartphones and tablets

There are many reasons as to why you need a portable battery for your gadgets. The most important one is how life is made easier by using mobile devices such as tablets and smartphones. When they run out of power, they become useless to us until we power up again.

If you have a one, you will enjoy a lightweight charging option on the go. You only need to have it pre-charged and then you can connect it to the phone when the need arises. After you invest in the best one, then you will not have to worry about dealing with a low battery at all.

Choosing the ideal one

There are some tips that can help you in getting the ideal option for all your needs. There are many things to consider and they include:

  • The size: this is not about how well it fits the pocket. It is about the power that can be carried within. Many of the options available usually has a number at the front that lets you know about mAh. This means milliamp-hour. When the number is higher, it means there is more power stored within and mire recharges doe the smartphone. Bigger mAh is also ideal for the bigger gadgets.
  • Power output: you need to consider how fast you will be able to charge your gadget using the alternative charging. It is important to be able to charge the phone/tablet as fast as possible. Your standard USB port on the component can fit the standard cable. However, it is important to know that the transmission can vary a great deal, depending on what you use.
  • Number of ports: this has to be considered especially if you will need to charge more that one device at a time. When it has a bigger battery, then you will discover that it may have more parts to make it possible to charge more than one phone or multiple gadgets at a time.
  • Cable: Each device has to come with a cable to facilitate charging. This can be a USB standard cable or the micro USB cable. It is important to know that it has to be charged beforehand. Some come with extra cables. This can be an important addition as it can help if you need to charge multiple devices at the same time.

Benefit Of Master Clock Systems

A master clock is a hardware device that obtains accurate time from a hardware reference and synchronizes slave clocks and time displays. The slave clocks rely on the master clock to display the correct time.

Once set, traditional, unsynchronized clocks drift away from the correct time at differing rates. After a relatively short amount of time, they can all display very different times. Correcting individual clocks can be a very time-consuming process which needs to be carried out at regular intervals.

GPS Master Clocks

Master clocks can use hardware time references, such as the GPS system to obtain very precise time. GPS is accurate to one-second in three hundred million years. Therefore, all time displays and slave clocks can refer to a highly accurate, legally traceable source of time. GPS systems require an antenna that is typically located with a clear view of the sky. Alternatively, where antenna installation is difficult, public internet Network Time Protocol (NTP) servers can be used.

Everyone Works To The Same Time

Many organizations can benefit from synchronized clocks. Staff all work to the same time, therefore meetings can start promptly, classes in schools start and finish as scheduled and shifts start and end consistently. Hospitals, manufacturing and pharmaceutical industries can accurately log events.

Low Maintenance

Once installed and correctly configured, slave clocks are virtually maintenance free in contrast to high-maintenance stand-alone clocks.

Automatic Adjustment

In many countries, clocks need to be adjusted twice a year to correct for daylight saving time. If a large number of clocks need correcting, it can be very time-consuming. Often clocks are located at height or in inaccessible positions that makes the task even more time-consuming. Additionally, adjustment often takes place well after the event, clocks will therefore be incorrect for an extended period.

Master clocks adjust for daylight saving time automatically, requiring no manual user intervention. Additionally, all clocks adjust at the correct moment so that a continuously accurate time is displayed.

An added advantage is that slave clocks can often be configured to display time in different time-zones, ideal for trading floors and meeting rooms.

Automatic Recovery

Power outages or failures can cause unsynchronized clocks to become inaccurate. Each clock must then be corrected individually. Master clock systems automatically obtain accurate time from hardware references such as GPS. Within minutes of the power being restored, slave clocks will be back up and running. Often no operator intervention is required.

Master clock systems provide many advantages over traditional unsynchronized clocks. They are easy to install and are virtually maintenance free. Also, using GPS time, they provide a high degree of accuracy and require no adjustment or manual user intervention. For more information on master clocks, see:

Having Fun With Virtual Reality

Technology is probably one of the best creations human beings have ever made. Not only is technology able to connect people but also gives us exposure to sights, sounds, and feelings that we haven’t experienced in our lifetimes.

With Virtual Reality, technology now allows us to experience a close to life environment in an imaginary setting. As per Wikipedia, Virtual reality (VR) typically refers to computer technologies that use virtual reality headsets to generate the realistic images, sounds and other sensations that replicate a real environment or create an imaginary setting.

Though VR is still relatively new to the public, there are already a lot of different ways to enjoy VR. Here are some of the virtual settings and activities that you can experience:

1. Flying

Ever dreamed of flying? Well, here’s your chance to experience how it feels like. Using VR glasses, you will be able to fly. VR glasses presents to people a very realistic image or video that helps wearers build the momentum and excitement for the whole experience. Aside from that, if you want to experience flying, you may try this new invention made by the researchers of Zurich University’s Interaction Design Program called Birdly. Birdly is a Virtual Reality console that allows a person to lie on a padded, cross-shaped apparatus and gives people the sensation of flying over buildings or across country sides.

2. Swimming

In other cases, a VR headset will also let you experience swimming. But it’s more than that. It will also let you feel what it’s like to be swimming under oceans with dozens of fish, sharks, and whales swimming around you. You will definitely feel like being underwater because you will be able to see and hear the beauty and sounds of these sea creatures.

3. Roller Coaster

If you’re just at home sitting on your couch and have got nothing to do, why not ride a roller coaster? Yes, it’s just that easy when you have your own VR headset! Start feeling the gravity as the coaster twists and turns upside down. There are many VR headsets that have built in games where you can truly experience an extreme roller coaster ride. There is also a simulator called “No Limits 2” which will let you experience roller coasters on a whole new level.

4. Skydiving

Skydiving is an extreme sport that some people can only dream of doing because it is really expensive. If you’re looking for a cheaper (and also much safer) way to experience skydiving, then VR is the way. Fly up to high altitudes with “Volo Airsport”, a physics simulator that lets people hang on to their life and experience skydiving.

5. Flight Zombies

If you are the type of person who is fascinated by the idea of a zombie apocalypse, then VR is your closest way to experience it. So, if you want to experience what it’s like to be in a scene of “The Walking Dead”, download “Zombie Shooter”. It is free on Apple and lets gamers to shoot and kill zombies that are chasing them through the VR headset.

How To Choose Drones

While drones are constructed for recreational purposes, you can also use them for professional aerial photography and videography, to inspect bridges, cargo carrying, wildlife tracking, and a wide range of other drone-related activities.

People who should consider investing in a drone

There is no harm in anyone owning a drone but you should highly consider investing in one if you love conventional remote controlled machines. These can be cars, boats, helicopters and many other units. You also should consider the units if you are into photography and videography. Do you have a deep interest in drone technology? You also should highly consider getting the units.

Factors to consider when buying a drone

For you to get the most from the unit you need to consider a number of factors. Some of these factors include:

Camera type: While most of the units come with their own cameras, there are others that have GoPro cameras attached to them. When making a purchase, go for one with a built-in camera. You should consider the number of megapixels that the camera has, video resolution, a method of camera control and distance of the camera.

Battery life: This is important as it determines how long you will enjoy having the drone. Consider the charging time of the unit, battery life, and whether you will need replacement batteries in your work.

Height and speed: There is no specific height and speed that your unit should have-it’s all dependent on your preferences that are guided by your needs. If looking for a unit to take live video action during a game, go for one that can reach up to 300 feet. This is to make it possible for you to easily capture the entire event.

Tips to remember when using the drone

When you buy the unit you need to consider a number of tips before you start flying it. When you make the purchase consider a number of terms such as RTF, BNF, ARF and any other that might be in the user manual. RTF means that you have to install a propeller before you fly, BNF means that the drone is completely assembled but you have to buy the controller separately.

While the unit might seem like a toy, you have to register it with the federal aviation administration. You should note that to make a registration you should be at least 13 years old. After making the registration you will be given a unit identification number that will be displayed in your unit. The registration can last for up to 3 years.

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.

We at iACT Global help you to get the insight of highly important and globally practiced cryptographic techniques. We provide you a thorough knowledge of network security system and related tools.

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.

Conclusion

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.

Versatility

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.

Technology For Smart School

The latest technology of RFID is one such bliss that helps institutions in a great way by minimizing a lot of labor in keeping track of attendance.

Challenges That Schools Face In Managing Attendance

Tiresome manual job: The schools and colleges usually have clerks doing extremely tiring manual labor of managing attendance of students and staff. This just means wasting tons of paper and even time, as the professors and lecturers might log in and log out at different times. This would ultimately take the entire day and along with that, maintaining a register of students across grades would be tiresome.

Human error: It is always there as a big challenge, which one might face while entering the time or marking students’ presence or absence. In fact, just a minor discrepancy or error in marking a student absent might reduce his attendance percentage by a great margin.

New academic session challenges: When a school reopens after holidays, usually new admission adds on. This calls for a newer register and more of repetition and bringing all the students to sign in again or logging into this system.

Keeping all of these issues, RFID school attendance system is a new-age solution for bringing in timeliness among the students as they log in.

In these days of increased security threats, one cannot simply ignore the fact that every new visitor to the school premises would require careful scrutiny. However, just having security personnel for that purpose might not do. This is where the RFID school attendance system and access control systems are useful.

How Is the RFID Attendance System Superior?

This system would not just be a tableau of meaningless time entries or log in and log out data alone. The access control and attendance systems would further use this data to convert it into analytical data. A student’s entry pattern and leave details or logging out early would be visible to the school authorities to bring the student back to the rulebook.

A great benefit of this system is that it can work independently, and remote access is enough for the school authorities to keep an eye on the entry system. They can set the time deadline for the last students to troop in the post, which they would not be allowed to come in with a warning.

Such automated systems are the need of the hour, when one can use everything to bring in regulations, discipline among the school students and even use technology to ease the administration process.

All About APK Files Android

APK stands for Android package kit. This is a file format that is used by the operating system in Android for the installation and the distribution of middleware and mobile apps. The files are actually analogous to the other packages like APPX for Microsoft Windows or the Debn kind of packages within debian based kind of OS such as Ubuntu.

So as to come up with the APK file, one needs an Android program for Android to be compiled and then all parts packaged into a single file that contains the code of the program. This can be files like .dex files. The APK file also has to have the manifest, certificates, assets and resources files. Just like any kinds of file formats that you may know of, the APK files are allowed to have any kind of name that is needed. The only thing that has to remain constant is the end which should be .apk.

They are a kind of archive file and found in the zip format packages that are based on JAR format .apk is the filename extension.

Installation

One can install the files in the devices that are Android powered just the way we install software on the PC. When one downloads and then installs an application on Android from official sites or other unofficial sites, they are actually installing APK ion the device.

It is possible for a person to install APK files directly in devices. This can be done without necessarily downloading them from any network. You can use a desktop computer and use different communication programs.

You can also use a process that is referred to as side loading. Usually, this ability to install from sites that aren’t official or from the file manager or direct from a desktop comes disabled because of different security reasons in many of the Android devices that we have. You can enable this by simply changing the unknown sources settings within the menu.

Why install an APK file

Usually, APK files get leaked before time and this allows you to have an easy access to many new features that would not have been availed to you. There are also some apps that certain regions can actually restrict. Having the APK files allows one to be able to bypass the various carriers so as to have the very latest updates on Google. This can take a lot of time to arrive on the network. In the Android device you are using doesn’t have access to the play site, then installing the apps may require having the APK files and it may be the only option that you have.

When using this method, you need to be careful not to end up with apps that aren’t legally acquired. There are services that may allow the download of apps that are pirated. Do your research so as to avoid breaking laws. Find a downloader that is well known for its efficiency.

Always ensure that you use a site that you can really trust since there are APK files that can have some malicious software.

It is important to choose a Google play apk downloader carefully so as to ensure the safety of your system and gadget as well. You don’t want to end up with a virus in your Android OS. Reviews and user comments can help. An online apk download should always be done safely.
