What are Artificial intelligence and Top AI courses and career prospects?

 

Artificial intelligence is the buzz word of today, especially in the tech world. Often times than not, people are confused with the words Artificial intelligence, what does it mean? Where does it come from? Are just some of the questions that are being asked today.

What is Artificial Intelligence?

Artificial Intelligence can be defined in many ways. One of the earliest definitions of AI was given by Mr. Minsky and Mr. McCarthy, two people who are considered as the fathers of the field of artificial intelligence. They described an as any task that has been performed by a machine that, if carried out by a human, would require the human to apply intelligence to complete the task. This essentially means that an AI is when a machine is able to think by itself and perform tasks that earlier, only humans were capable of.

Why is Artificial Intelligence important?

The fact that humans are always trying to bring in new technology that makes lives easier is what drives research and development in AI. We all know that humans, though skilled, can never do the number of calculations that a computer can do. By using complex AI and ML (machine learning) models, we can analyze a lot of raw data and fit them into patterns. For example, there is an AI model that can tell you if you have breast cancer with very high levels of accuracy with a little data about you. Reaching this level of accuracy is not possible for doctors also. AI will be able to make the lives of humans easier and improve the living conditions of future generations.

Can you learn AI?

The thing about Artificial Intelligence is that though there is much need for people who are trained in developing AI, there are not a lot of people in the field right now. Most companies have reported huge vacancies for research and development using AI and AI-assisted technologies. Even top companies like Google, Facebook, and so on are working towards integrating AI in their platforms. It is estimated that around 72% of all AI jobs are still vacant. This means that it is a great idea to learn AI at this point in time to improve your chances of being employed.

What are some of the AI courses that are available?

There are a lot of resources online for learning Artificial Intelligence as well as AI-assisted technologies. Many of these online courses are free, and hence you will not have to pay for them. But, the issue with free courses is that you often do not get a certificate after completing the course. Having a certificate is important as it will help you in getting a job.
Here are some of the popular courses in AI and ML:

1. Principles of Machine learning by Microsoft:

With three experienced instructors, Microsoft offers this course as a part of their professional program certificate in data science. As a part of this course, you will learn machine theory as well as practical scenarios. The duration of this course is 6 weeks, with you needing to dedicate about 3 or 4 hours per week to complete it. The course covers important topics like regression models, non-linear models, clustering techniques, and so on. Though it is categorized as an intermediate level course, many freshers have also been able to understand the topics clearly with minimum previous knowledge requirements.

2. Artificial Intelligence Graduate certification by Stanford University:

The AI course offered by Stanford is a good one for beginners. This course can be taken up online as well. This course will give you a solid foundation in AI and AI-assisted technologies and also discuss some of the background processes that help in the development of AI. Some of the topics that are included in this course are Data mining and representation, Probabilistic models, perception and cognition, logic and reasoning techniques, and so on.

Artificial intelligence

3. Machine learning specialization by University of Washington:

This is a collection of 5 different intermediate level courses. This course is designed to help students specialize in machine learning. The course in itself will take about 25 weeks to complete and required a minimum effort of 5 hours of 8 hours per day per course on the part of the learner. The course is completely free.

What are the career prospects for AI?

The journey of Artificial Intelligence and machine learning often start with data science. Companies are facing a huge shortage of data scientists and are offering jobs that are paying very handsomely for skilled data scientists. You can also move towards the core of AI in research by building your own models for the analysis of data patterns and still get paid very handsomely by top companies located all around the world.

DevOps engineering and Tools of DevOps.

 

What is DevOps?

DevOps is a development strategy. DevOps is a development strategy for software that is used to bridge the gap between the IT staff and the developers of the software. The main advantage of DevOps is thatcompanies can release small features in a short amount of time and also incorporate the feedback that they receive quickly. Added to this, development using DevOps engineering will also result in fewer failures of software in the form of bugs. Also, the time taken to spot these errors and correct them is also reduced with this development strategy.

Who is a DevOps engineer?

A DevOps engineer does not usually code software from scratch, though a thorough knowledge of the same is required. Instead, the engineer regularly updates short bits of code to adjust the software for a better and effective experience. A DevOps engineer is equipped to manage the IT infrastructure that is required to support the code in a multi-tenant or dedicated or even hybrid cloud environment. The tasks under the DevOps development strategy may include provisioning required resources, selecting appropriate models for deployment, using the testing protocol to test the software before releases, analyzing results as well as troubleshooting any problems that may arise. In order to make these tasks easier to handle and efficiently develop software in this development model, there are a hot of DevOps engineering tools that are available for use.

devops

What are some of the widely used tools of DevOps?

1. GIT:

Perhaps one of the most widely used tools in DevOps development strategy is GIT. There is probably no developer who has not used GIT at least once in their lifetime. GIT is essentially a control system for versions of software created by the user. It is used to track all the changes that have been made to your code. Because DevOps development mainly deals with updating code and releasing newer versions, this is a boon for engineers. GIT also helps DevOps engineers in easily coordinating the workflow with the members of their team. GIT helps engineers in a faster release cycle and also supports pull requests. One of the most important things about GIT is that it is an open-source tool that can be used for free.

2. Jenkins:

One of the most important parts of DevOps development is continuous integration. This ideal with the integration of various stages of DevOps. Jenkins is an automation tool that is open source in nature. It is written in Java and has plugins for the purpose of continuous integration. This tool can be used to build as well as test your software codes continuously, in a real-time manner. Jenkins mainly works with plugins. The community of Jenkins already has most of the tools that an engineer might require. But, in case you do not find a plugin that is suitable for your requirements, you can always build one, and if you choose to, you can share this with the community of DevOps engineers. Because Jenkins is coded in Java, integration to other major platforms will not be problematic.

3. Selenium:

Writing code is an important part of development, but testing it is also important. This is where a tool like Selenium comes into the picture. Selenium is a software that has testing frameworks for web-based applications. With Selenium you can create an easy interface to test your codes automatically. Selenium, like the other two tools mentioned above, is also open-source, meaning that you can use it for free and also change it if you need a more customized experience. You can write your scripts in multiple popular languages like Python, Java, Ruby, C#, Perl, Php, and JavaScript. Another important feature of Selenium is that it supports testing protocols for all popular platforms like android and iOS. As a DevOps development tool, you can use Selenium to crease automatic regression suites as well as tests that are browser-based.

devops

4. Puppet:

Puppet is another popular tool that is used for DevOps development. Puppet is a configuration management tool that can help manage your servers and also automate the methods that are used for inspecting, operating, and delivering the software code written by you across the entire lifecycle along with platform independence. Another good thing about puppet is that it is also an open-source tool that has a long commercial track record with more than thirty thousand companies across the globe using it on a daily basis. Also, the puppet DevOps tool is based on the master-slave architecture that is one of the most helpful architectures for developers of DevOps related software. With this feature, you can perform dynamic scaling down as well as dynamic scaling up of your machines. The master and the slave in puppet communicate with each other through encrypted channels that are secured with the latest SSL encryption techniques.


 

 

How Blockchain Works.

 

Blockchain is a technology that has become popular in recent years. Many companies around the world are figuring out where they can incorporate this technology in their daily routine to make services they provide better. IN essence, blockchain is a ledger. A ledger is a book that is used to make a note of some transaction that involves more than one party. Blockchain can also be thought of like a dairy that cannot be manipulated by anyone.

What exactly is blockchain?

In order to understand the true use of blockchain, let us take a small example. Suppose you have to transfer some amount of money to a friend. You go to the bank, and you put in a request asking them to transfer the money, and you give the details of your friend’s bank account, and your bank debits the money from your account and then transfers it to your friend’s account. Now, there is a list or book that the bank maintains that records all the transactions that are happening from your account. Now suppose your friend says that he or she has not received the money that you have transferred, you will show him or her a copy of the transaction receipt from the bank, and the dispute is settled. The real problem in this situation is that the ledger of the bank can be forged by a third party like a hacker as they please. All a hacker has to do is change one entry in the bank diary to make it seem like the money has not been transferred at all. This is where blockchain comes into the picture.

In order to understand how blockchain works, let us take another example. Think of a spreadsheet that Is being shared by a group of friends. Now, this sheet has many copies of it made, meaning that everyone in the group has a copy of the sheet in their computers. Now, if this sheet is the bank’s transaction sheet, like in the previous example, then the hacker who is trying to manipulate the entries of the sheet will not have an easy job. He or she will have to edit all the copies of the sheet, which is pretty impossible. This is how blockchain works. Anyone can access the sheet, but no one can edit it.

Block chain

In the spreadsheets that are discussed above, there are rows and columns that are used to enter the data. In a blockchain, these are called blocks A block is essentially a small chunk of data that has been added to the blockchain. When many chunks of data are added in a chain sort of fashion where one is connected to another, the entity becomes a blockchain. Often, the first block of data in the blockchain is called the genesis block.
Just like how the spreadsheets in the example were distributed among a group of people, the blockchain ledger is also distributed in a network. All the peers in the network will have a copy of the ledger in their computers.

Why is blockchain better than a traditional ledger?

As we know, traditional ledgers can be manipulated, but a blockchain entry cannot. Some of the other key features which make blockchain a better option are:

• Distributed:

Because the blockchain is shared by all the peers in a network, it becomes practically impossible for a hacker to manipulate the information. The hacker would have to physically change the entries in all the ledgers of every single peer in the network, which is practically impossible.

• Peer to peer:

The blockchain system has no central authority that has the complete right to change the data or manipulate the data. All the participants in the blockchain will talk to each other directly. This means that the exchange of data can be made directly with a third party.

Block chain

• Security:

Advanced cryptography methods are used to secure the data that make the blockchain ledger tamper-proof.

• Consensus:

This is perhaps the most important feature of the blockchain. This gives the blockchain the ability to update the ledger with the consensus of all the parties that are involved. There is no central authority that has complete control to make changes or update the edger. Instead, the data in the blockchain can be updated, and the update has to be validated by all the peers in the network against strict criteria that have been defined in the protocol that is used by blockchain.

How does the technology work

A node will initiate a transaction by created and signing it. This transaction is sent to all the peers in the network using a protocol called the flooding protocol. The transaction has to be validated by at least 6 peers, and then it is added to a block that is put on the network. This block becomes a part of the main ledger. The transactions are then reconfirmed every time a new block is made.

Digital twins, understanding the concept and applications.

 

Imagine a world where you can have a non-living physical entity with you that helps you out with all your needs. A digital twin refers to a digital replica of an actual physical asset like a process, a product, or a service. A digital system can be used to process, collect, deploy, and so much more. This pairing of a physical, as well as a virtual model, means great things for the world. It allows the analysis of a clot of critical data; it helps in monitoring of systems, it helps in predicting and resolving problems even before they occur and also plan for future tasks by way of running systematic simulations.

The whole idea of digital twins has been gaining weight in recent times because of the advancements in the field of the Internet of Things (IoT). With IoT helping build models of digital things, we can expect some of these in the market very soon.

How does IoT tie-up with the digital twin’s concept?

IoT consists of sensors, processors, and actuators. Any smart component will have a working sensor that is used to obtain real-time data and status updates about some parameters. These sensors are integrated with an item in the physical world to get data in the digital world. These sensors are connected to online cloud platforms that receive this data and perform a lot of analytics as processing.
With the emerging technologies that are being used in coherence with IoT, like Artificial Intelligence as well as Machine learning, it is expected that companies will start deploying digital twins for all critical decisions and data collection. Most of the analytics that is carried out in these cloud platforms are used to support business and bring them to new levels.

Digital Twins

Are digital twins being used anywhere?

A working virtual environment is a boon for engineers. In many situations, it is impossible to test things that are not built for this world. For example, NASA (National Aeronautics and Space Administration) has been building rovers and satellites that are to work in different conditions than on earth. Though some situations can be recreated artificially, like the terrain of the planets, not everything can. Things like repairing components on the international space station and so on require a lot of calculation even before they are carried out. In such situations, a digital twin can be very beneficial.

NASA usually builds a small prototype of what they want, most with sensors and actuators, and puts these to the test. The devices are subsequently manufactured only if they meet all the requirements that are prescribed, and the virtual environment tests have gone fine. Once the physical system has been built, they tie it with the virtual twin through an array of sensors so that the digital twin has all the information that is available on the physical twin.

What are some of the other applications of digital twins?

Digital twins can be used in almost every single sector to improve customer service, make better operational decisions, get better insights, and so on.

Some of the major applications of digital twins can be seen in the following sectors of commerce:

a. Automobile sector:

With cars and bikes getting smarted by the day, digital twins are in high demand in the automobile sector. They can be used to create a virtual model of a connected vehicle and made to capture the operation as well as behavioral data of the vehicle. This will help in analyzing the performance of the vehicle and help make the vehicle more effective. This will also help the automobile companies provide a more customized experience for customers.

Digital twins

b. Manufacturing sector:

The deployment of digital twins can change the whole way goods are manufactured. The digital twins will have a significant impact when it comes to the design of the products as well as the methods of how they are manufactured. These systems can help manufacturing units optimize their resources and bring in more profit. You can identify weak spots in the manufacturing process, techniques that give more errors, materials that are prone to become problematic later on. The ways of integrating a digital twin in the manufacturing sector are limitless.

c. Smart cities implementation:

When it comes to planning and implementing smart cities, the digital twin model can help the city planners as well as the policymakers of the city. These people can plan a better smart city with the data that they have gathered from various wireless sensor networks that are spread across the city. This crucial data will be able to help planners in planning not only for the current generation but also for future generations. This proper planning will reduce the need for building, demolishing, and rebuilding structures like bridges and flyovers across the entire city and also reduce the environmental impact that a modern city has on the environment.

Java 64 bit: What is new, and how is it better than 32 bits?

 

What is Java?

Developed in the mid-1990s, Java is a popular programming language that is used to develop software for multiple platforms. The specialty of a code written in Java is that the code that is compiled from the source code can run on most popular operating systems like Mac OS, Linux, Windows, and so on. The syntax of Java is almost similar to C and C++, with minor variations.

Java is mainly used to develop programs that are able to run on browsers. These help in making rich and interactive Graphical User Interfaces (GUI). Before Java, webpages were mostly static without any graphics. Now, Java is slowly being phased out for the purpose of building GUI based browser apps, and other technologies like adobe flash are taking over. Though this is happening, many critical program interfaces are still being built using Java.

Developing programs in Java requires an SDK (Software development Kit). This kit contains three main things: a compiler to compile the source code, an interpreter, and a document generator. Along with these, there might be other tools as well that help coders develop java code. Java has become so important that computer science engineers all over the world still learn it and write code with it. Most universities still teach it as an important subject to understand the art of programming.

Java 32bit

What is 32-bit architecture and 64-bit architecture?

In 32-bit operating systems, there is 4096 MB of RAM that is available for use. Technically speaking, you can allocate about 4 GB per process. When it comes to the Windows Operating system, the OS divides the allocated process address space into two halves. The first half of the process address will be reserved for the operating system to use itself. This essentially means that this space cannot be used by any other process. The second half of the allocated process address is for any user processes.

Also, the address space that is allocated to the user process has to be contagious; this means that in reality, you are left with only about 1.6 GB to 1.8 GB of heap space left on the Windows OS. Also, the Basic Input Output System (BIOS) will be occupying some of the space in this heap. This means that at the end of all considerations, you are left with only about 1.5 GB of usable space for your process.

Why are 64 bits better?

When it comes to 64-bit system architecture, theoretically, a 64-bit system can access about 17.2 Billion Gigabytes of system memory! This is an incredible number and will look like it solves all the problems that a 32-bit architecture system had with Java; in reality, the whole thing does not work that way. In the windows operating system, especially the home editions of the OS, the memory access is still limited to 16 Gigabytes of RAM. The professional, as well as the ultimate version, can use about 192 GB of RAM each. Each application that is running on the 64-bit architecture operating system can use up to 8 TB of virtual memory.

Differences between the 32-bit Java and 64-bit Java.

• Firstly, if you are running a 32-bit OS, then you will only be able to install the 32-bit version of Java. But, if you are using a system that is based on the 64-bit architecture, then

• The 64-bit JVM (Java Virtual Machine) will be able to allocate more memory than the 32-bit JVM.

• The 64-bit JVM uses the native datatypes. These data types are better when it comes to the aspect of performance. Though they might need more space to operate, considering that in most machines these days, there is no shortage of space, this will still be a plus point for the 64-bit version of Java.

Java 64 bit

Is garbage collection an issue with the 64-bit Java?

In order to understand why there are longer garbage collection pauses, we have to understand what actually happens. When you build up a bigger eap because of the 64-bit version of Java, there is more work that has to be done by the garbage collector to process this data. When it comes to practical applications, the programmer must ensure that while he or she is building heaps that are bigger than 12 GB to 16 GB, he or she must fine-tune the process.Without measuring and properly fine-tuning the garbage collection process, you may end up with a pause that is as long as a whole minute. This problem can be easily solved by partitioning the heap and does not pose any big problem to an able coder of Java. Other ways of solving this problem are by allocating a bit of memory of the heap and also by building the project on different Java virtual machines.

Though there are some consequences of using the 64-bit Java, the pros outweigh the cons.

Internet of things and IoT Devices: Easy explanation.

 

In the age of voice-powered devices like Amazon’s Alexa and Google’s Home, we continuously hear the term Internet of Things. What are these things, and how do they matter? Read the article to find out more and understand what IoT actually is.

What is IoT?

Internet of Things is an interconnection of devices that are able to perform a specified function without the need for human intervention. These devices that perform a function are what are known as ‘things’ in the Internet of Things. The main aim of IoT is to be able to perform functions without a human having to instruct the device more than once.

Smart home example:

Let us take an example of a Smart Home for the purpose of understanding what IoT actually is. Imagine that you are headed home, and you just sit in your car at the workplace. You instantly get a notification on your phone that some items from your fridge are missing along with a picture of the inside of the fridge. You can then proceed to the grocery shop to purchase these things. Things that are not required fresh, like packed items in tin cans, are ordered automatically. As soon as you reach home and open your door, the lights in your house switch on automatically. As you go out of a room, the lights turn off automatically.

The kettle has already made a cup of coffee for you to enjoy in the evening. These are just some of the things that happen in a smart home.

Iot

Analysis of how smart home works:

Now, in this example, there is a lot of ‘sensing’ that is going on. The IoT devices sense that you are getting into your car. The fridge senses what is missing and places an online order for some items. The lights sense that you are in the room and turn on and off accordingly, the coffee maker turns on as soon as you reach home so that hot coffee is ready for you. All these things make life easier for us, and that is the ultimate goal of IoT.

There are three processes that make up an IoT environment, first is sensing, the second is processing, and the third is actuating, in simple words, the door senses that you are opening it and it processes this information, as a result of this process, it is determined that the lights have to be turned on, so a command is sent to all the lights in the house to turn on. This turning on is the actuating.

IoT uses a network of devices that are connected to each other and work with each other to make jobs easier for you. These devices are all fitted with a microcontroller or are connected to a cloud service that does all the analyzing for you. This is what IoT basically is.

Where can IoT be used?

The short answer to this question is that IoT can be used anywhere where human intervention is usually required. Need to turn on the washing machine, attach an IoT device to do it for you. Need to water the plants, get a smart watering system for your plants that turn on the water when there is dryness, get a smart gas sensor that tells you when there is a gas leak in your house, the possibilities are endless with IoT.

The Internet of Things is now being used in major industries as well to automate the workflow and to improve the efficiency of the production. IoT is also being used by government agencies to build smart signals that detect traffic and adjust the traffic signals accordingly. Smart street lighting is another place where IoT devices are being used to limit energy consumption.

It is estimated that by 2020, there will be more IoT devices in the world then there are people. This estimation only shows us how IoT and IoT assisted technologies are becoming more evolved day by day.

IoT

How are IoT devices different from normal devices?

The main difference from an IoT enabled light and a regular light is a method by which it turns on. An IoT smart light can turn on without anyone having to flip a switch. A regular one will need someone to turn on the switch to turn on the bulb physically.

An Internet of Things device may consist of a communication module like Bluetooth or Wi-Fi or other such technologies to receive commands wirelessly. These devices might also have a small microcontroller built into them to process the information they receive and relays to supply power to the main device. A working internet connection is required for an IoT device to receive signals and work properly, and hence there must also be a gateway or a router that helps to connect these devices to the internet.

Main issues of Android apps and their solutions.

 

The Android operating system is one of the most popular operating systems’ in use today. Most of the smartphones that do not run on the Apple iOS running on the Android OS. Just like any other operating system, Android OS also has some minor bugs and glitches every now and then. This is mainly because of how apps are coded and integrated with the Android OS. Because it is one of the most popular OS for mobile-based applications and some new laptops, there are tons of apps and services that run on the Android OS.

While most of these problems just go away when you close the app and then reopen it, there are a few bugs that may need some work to be done in order to make them work properly. These fixes are very easy, and you do not need to be a computer engineer who programs apps to use them. Read on to find some of the main issues of android apps and how to solve them easily and quickly.

1. Battery drain:

Perhaps one of the most common problems that people face with android apps is the amount of battery that these apps drain. This can effectively kill your mobile phone’s battery within a few hours if you are a very intensive user. There are some easy ways to fix this battery drain problem:

a. Clear all background apps:

Click the apps button on your android device (usually on the opposite side of the back button) and physically remove the apps that are working in the background by pushing them away. This will help close these apps and stop draining the battery in the background.

b. Set up power-saving modes:

Most mobiles these days have power-saving modes. Go to settings, find the battery option, and select the power saving mode that looks the best to you. Many mobiles also allow you to customize the times that the power saving mode is turned on and can also turn on when the battery reaches a low power.

Android apps
2. Sudden freezing as well as slow user interface response:

This is a very common problem in all devices, and not only restricted to the android OS. Sudden freezing of apps as the phone ages is common. Even installing a large number of apps on your phone will lead to this. If your phone does not have a very powerful processor and low RAM, then the phone will be laggy. Fortunately, there are things that you can do to solve this problem:

a. Uninstall unwanted apps:

There is a lot of bloatware that comes preinstalled in some phones. If you do not need these apps and you do not use them, you can uninstall them. If you cannot uninstall them, then you can disable these apps so that they do not waste any space on your phone. Just go to settings, apps, and then choose the app and uninstall or disable.

b. Clear cache:

The cache is the data of an app that is stored on your phone. You can resolve most speed issues of an app by just clearing out the cache. Cleaning the app cache is easy; all you have to do is g to settings then apps and then click on the clean cache. You should restart the phone once you clear the cache for optimal usage.

3. Google play store crashing repeatedly:

Google play store is the go-to place for all android apps. It is also the official platform from where you can download apps without having to worry about viruses and security issues. Google play store also updates the apps on your automatically if it is told to do so. If google play store is crashing as soon as you launch it, the most probable reason is a cache that is corrupted. Unfortunately, you cannot just uninstall and reinstall google play. So, in order to fix this particular problem, you have to clear the cache, just like how you did for the other apps. Once you clear the cache, restart your phone to start the play storeAndroid apps

4. Issues with connection:

Smartphones are always connected to the internet via Wi-fi or cellular data. Your phone may also be connected to another device via Bluetooth. Many times, because of prolonged connections, there are problems with the connection interfaces, and the connections will not work as they are intended to. Solving a connection related problem with your android device is pretty easy.

a. Go to airplane mode:

Android has an inbuilt feature of the airplane mode. In the airplane mode, all communication interfaces like cell signals, wi-fi, Bluetooth are disabled. Just go to settings and find airplane mode under connections. Turn it on for about 30 seconds and then turn it off to restart all the communication interfaces. This should solve most of your problems.

Top 10 most productive gadgets to save time.

 

Time is everything in the fast-moving world of today. Business professionals, students, homemakers, and everyone else also have a shortage of time. In these busy times, technology often comes to our aid. So, here is a list of 10 of the most productive gadgets that you can use to save time and spend it on you.

1. Bluetooth tracking tags:

This is a common story. You are all ready to go to the office or to school, but you can’t seem to find your keys. You look all around the house, and yet you cannot find your keys. In this morning battle with your keys, you are losing a lot of precious time, time that you could have used otherwise on yourself or at work. Because you are late, you will drive more recklessly and may get stuck in traffic and waste more time. The answer to that problem is here in the form of Bluetooth tracking tags. These are very easy to use; all you have to do is hook one up to your keys, your wallet, or anything else you can’t find. You can make the tag ring, or you can also look at where you last used it on your phone, saving you lots of time.

2. Robot Vacuum:

Cleaning the house is a very stressful and time-consuming job. Now, all you have to do is get a smart robot vacuum cleaner that will do all the work for you. All you need to do is charge it up and put it down. Some robot vacuums these days have inbuilt time sensors that help it turn on at a specified time; this means that you can schedule the cleaning of your house when you are away, and by the time you are back, your house is clean and tidy with minimum effort on your part.

3. Garment steamer:

Gone are the days of standing up and ironing out your clothes for the week. With the garment steamer, you can steam iron your clothes in a matter of seconds and not have to think about it again till the next week. There will be no more standing over the ironing board for hours for wrinkle-free clothes; all you need is a handheld or professional garment steamer. The great thing about this is you can use it to steam things like curtains and not even have to take them down!

Productivity

4. Vegetable slicer:

If you are a homemaker or a working professional that cooks, you know that cutting vegetables take up a lot of time. Just get an electronic veggie slicer to do the job for you in seconds, and don’t waste any more time on it.

5. Smart speaker:

With a smart speaker like the Amazon Alexa or the Google home mini, you don’t even have to get up from your place to do small things like turning on the lights, changing the music, and so on. These smart devices will listen to your voice commands and do what you need in a jiffy.

6. Power shower scrubber:

Soap scum and hard water stains are very irritating as they are difficult to remove. With a power tool like the power shower scrubber, gone are the days that you would manually have to spend hours of your weekend scrubbing and scrubbing. With a replacement of attachment heads, you can use this powerful tool to clean almost anything, from your sink to your taps in just a few minutes.

7. Mini electric air compressor:

This is a boon for office goers as well as homemakers. If you think you have low air in your car and you don’t have any time to go to the petrol bunk for some air, all you have to do whip out the mini air compressor and let it inflate your tire in seconds. Homeowners can use it to inflate anything from balls to balloons to air beds.

8. Automatic pet feeder:

If you have a pet that wakes up early and needs to be fed, you are definitely not getting enough sleep. Buy an electronic pet feeder that can feed your pets at the specified times in the day and save more time for yourself.

9. I have a timed electric stove:

If you have ever had milk boil over the pot, you know that you shouic stove that has an inbuilt timer that can turn off the stove after a while. You no longer need to stand next to the pot as it is boiling, just put in the time and do better work!

Productivity

10. Magnetic cable clips:

Augmented reality vs. virtual reality.

People nowadays want to experience everything. In order to do this, technology has developed products in the form of Virtual Reality (VR) and Augmented reality (AR). In a broader sense, there is also another technology that is a combination of AR and VR and is called MR (Mixed Reality).

What is Virtual Reality?

Virtual reality is focused on providing you with a complete immersion experience. In VR, the physical world is shut out, and you are not exposed to any of the physical surroundings. Experiencing VR is very easy; all you have to do is get a VR compatible headset, put your phone into the headset after setting it up and then let it take over. With VR, you can experience anything that you can dream of. If you want to know how it feels like to stand atop Mt. Everest, you will know. If you want to feel like swimming with the dolphins in the Pacific Ocean, you can experience it. If you want to know how it feels to be in a rocket ship, you can take a virtual journey to the moon.

The immersion of a person into VR is very dramatic.

Many users have reported that they feel that they are doing physical activities in the virtual world. For example, if you are riding a bike and you hit a pothole, with VR, you can actually feel your body bounce up to a certain degree. This is the power of the mind with Virtual Reality.
Many companies are doing research on VR and are building up new experiences for people using VR. In the near future, VR will become so advanced that you can even have a full-body experience, like in a simulator of jumping from an aircraft. VR helps people train for things without having to injure themselves. For example, if there is a soldier who has to learn how to jump out of an aircraft and deploy a parachute to land properly, he or she can learn how the experience works with VR in a safe environment. Once they are sufficiently satisfied that they know how it works, they can move on to the real world being partially trained. This is applicable to so many other scenarios, like fire tenders, medical personnel, and so on.

Augmented reality

What is Augmented reality?

As the name suggests, Augmented reality just augments something to our already present physical world. It just takes our current reality, that we are surrounded by and adds something to it. AR headsets are usually clear glasses, unlike the bulky and completely covered VR headsets. While a person has a more immersive and real like experience with VR, AR provides more possibilities and more freedom to the user. The real world is not completely cut out from AR, and this means that you will not have to wear those heavy and bulky VR headsets. The difference between AR and VR can be understood with an example. Above, we discussed you are swimming along with dolphins in the ocean, now that is VR. But, if a dolphin suddenly comes out of your wallet, then that is AR.

One of the widest acceptations of AR is the popular game Pokémon Go. This is still considered a game that brought about a shift to the AR market and showed companies that people are ready to embrace a world of AR as well. In the game Pokémon GO, the user would take their phone around with the camera turned on, and they would find little creatures, called Pokémon in different places, you could find one in your front lawn, one in the parking space of your office building and so on. This game became so popular that the servers often crashed.

With the introduction of new-age AR devices like google lens and Microsoft’s HoloLens, the use of AR will only become more substantial in our daily lives.

Virtual reality

There is a lot of research that is being conducted in both these technologies to find avenues where these can be used not only to give users a better experience but also as technologies that we would be using daily. For example, in a top university, VR research has been taken to the next level by integrating smart smells. So, one day in the future, if you are watching a movie where the people go into a bakery, you will immediately get the smell of fresh bread and thus make it feel like you are in the movie along with the actors. There is huge commercial potential in both these fields, and that is why tech giants like Microsoft, Google, NVIDIA, Lenovo, and so on are all doing their own research into bringing Augmented and Virtual reality as a component in our daily lives.

Benefits of cloud hosting and Best cloud hosting providers under 10$.

Websites are everything these days. Every successful company has one or more than one website. Even small businesses like hair salons, car washes, window repairs, and so on have their own websites. It has come to a point where people do not trust a company that does not have a website. A website serves many purposes for a company. First of all, it increases the brand awareness of the company and the products that they offer. Secondly, it creates a sense of trust in the brand. A company looks more dignified on their websites.

A website also lists all the important information of the company, right from the address of the company till the working hours, people no longer need to call to find out where the company is or when they work. This is one of the most basic uses of a website. Websites are not only made for companies; many individuals, like celebrities, also have their own websites. Projects that are currently underway, also have their own websites.

Inorder to have a website that is available on the internet, a company has to have a partnership with a popular hosting provider. A cloud hosting service is essentially a service that displays your website on your behalf. It is where the data on your website is stored. The cloud hosting service provider will have high capacity servers that will have high up times.

Cloud Hosting

  • What are the benefits of cloud hosting?

a. Low cost:

If you are a small company, then set up your own servers to host your website will be an extremely costly affair. Not only will you have to spend on the hardware requirements in the form of huge servers, but you will also have to have a space to house all the servers and related equipment, but you will also have to pay network and server engineers to maintain the servers properly and ensure that you are connected online always.
Cloud hosting services are very cheap these days; you can start with as little as 10$ a month. With a cloud hosting service, you need not bother with maintaining servers, allocating space for them, and hiring more engineers.

b. Scaling problems:

Suppose you do invest a lot of money in servers and everything, and because of your website, your company grows very big. As you grow bigger, your needs also increase. This means that you will have to spend again to upgrade your servers to handle the new loads that it is presented with. This is, again, a huge investment.

With a cloud hosting service provider, you will not have these problems. Cloud hosting services have a very big infrastructure, and upgrading to a bigger plan is just a click away; you do not need to worry about anything else regarding scaling up or scaling down your online presence.

c. Speedy server setup:

You can deploy a website in just minutes with a hosting provider. If you think about your own server, it will take you weeks to do the same thing, if not months. All you need to do with a hosting provider is tell them what plan you want, give them the data that you want to be displayed on the URL that you have purchased, or have to purchase and then sit back and relax as the website is deployed in just minutes.
