Kotlin: Hot Android App Development Trend in the Market

Since the time of its invention, Java is ruling the Android app development market. Recently, another modern programming language is becoming immensely popular among the Android developers worldwide. The ranking of Kotlin is getting so higher with the time that the experts are expecting soon, this would become one of the top 20 programming languages ​​ever! This article is going to give you a brief idea on Kotlin and why this language is getting so much attention from the developers.

An Introduction to Kotlin

This is an open source language and based on the JVM (Java Virtual Machine). Kotlin is the brainchild of renamed Russia-based JetBrains programmers. This new language is now a part of the latest Android Studio version 3.0.

Since more than 20 years, Java is ruling the market and obviously, the impossible features and functionalities that it offers are of ace quality. Otherwise, ruling a market peerlessly is not possible for this long time. However, it may sound strange but you can not ignore the "aging" facet of Java. Here comes Kotlin in the picture. A new, modern, advanced Android dedicated language offering a remarkable set of benefits. Read on and go through the list of benefits that you can avail if you opt for Kotlin.

  • Interoperability

Can you think of the situation, where in the same project, two different programming languages ​​are coexisting? Well, with Kotlin, this is possible. While using Kotlin, you do not need to switch to a different project or no need to change the existing code. You can effortlessly use the features offered by it and make the app development process easier.

  • Less Coding

Let's think of a simple thing! Why would you write a hundred lines of codes when you can do the task by writing only a few lines of code? Yes, the number of codes you need to write in Java to do a special task, you can do it by writing almost 20% less amount of codes in Kotlin. Well, no wonder why worldwide Android developers are going crazy over it!

Undoubtedly, this 'less coding' feature not only diminishes the boilerplate coding amount but also makes execution of the code better.

  • Easy Learning Curve

One of the most intriguing facts about Kotlin is its easy learning curve. Unlike Android O version, you can easily master it by going through the list of language references. It has a lean and intuitive syntax that is gentle for the Java experts. If you already have skills in Java, learning Kotlin is nothing to you!

  • Safe and Secure

Working with Kotlin is a bit safer option for the developers. Wondering why? Well, with the help of it, you can avert critical errors such a NullPointExceptions. The compiler of it automatically casts mistakes. Sometimes, a developer might overlook a small mistake but all thanks to the Kotlin compiler that would not allow doing so.

  • Zero Adoption Cost

The term 'free' or 'zero cost' easily grab attention of people! Kotlin would not disappoint the users in this case as well. How? Well, this is an open source language. Here, you would not have to spend a single penny to get it. Simply get a converter tool that can convert all the existing Java files into Kotlin and that's it! You are all set to start with this impressive high-end language.

Even though Kotlin is gaining its popularity in the market in an exponential way, for the beginners in the Android app development field, it is always advisable to start the learning process with Java.

Security and Privacy of Google Play Apps by Google

Most of the android apps focus on security and privacy to make sure everybody has a helpful experience in discovering and installing apps and games they love the most. With this piece of write up, you will get information about the latest changes which Android developers are facing, as well as explaining the motive for each change, and how these securities facilitate Android devices to become more protected and secure for the elongated term.

To make the apps more helpful and protected android developers will have to work on new requirements if they want their apps to be accessible on Google Play in the future. Those include supporting a latest Android version and adding support for 64-bit native code in the apps in the future. Moreover, Google will start including some safety metadata to perk up APK validity verification.

How to secure your apps?

There are several reasons for requiring an app to support the latest API version is benefiting the app with security and privacy that Google has been incrementally adding together to the Android platform. This does not signify that Android should stop supporting older Android versions, which is still encouraged. Google also illustrated that fresh apps published on Google Play from August 2018 need to have API level 26 (Android 8.0) at least in it using the target SDK Version manifest attribute.

The condition to hold 64-bit CPUs only have an effect on apps that comprise native libraries in them. Google says that more than 40% of at present used Android devices have 64-bit support and that their performance is considerably enhanced by running 64-bit code. For this Google Play also supports 32-bit apps and devices, so 64-bit support is an addition to the 32-bit support using a single APK or numerous APKs. This is one of the plus points for the developers which they can use in the future.

In addition to above, developers have almost 2 years period to transition to 64-bit, since this condition will start in August 2019. For now, you can start adding a little amount of security metadata on the pinnacle of each APK to confirm that it was authoritatively distributed by Google Play. The metadata which developers will add to APKs is like a Google Play badge of authenticity for your Android application. Surely 2017 has been an incredible year for developers who have seen growth and accomplishment on Google Play.

Wrap up

With all these features and the upcoming latest updates, we look forward to seeing the Android and Play ecosystem continue to flourish in 2018 and ahead. In the end to conclude this section we can say that Google will start to automatically add certification to its apps in early 2018. This modification does not have any effect on apps’ behavior, but surely will be used in the future to allow new distribution opportunities with the endeavor to help users to keep their apps up to date.

Protect Your Android Device From Malware

The adoption rate of mobile devices continues to soar, with Android leading the way. The open-source operating system that is led by Google is now found on more than half of all smartphones. This massive user base has caught the attention of cybercriminals, who have begun to double down on their efforts to illegally obtain personal information from Android owners. While most mobile malware is found in countries like Russia and China, users from Europe and the United States aren’t completely immune.

There are a few simple steps you can take to avoid getting your data locked up in an encrypted jail.

  1. App source

Only download apps from trustworthy sources like the Google Play Store. Be wary of any site that allows you to download paid apps for free.

  1. App permissions

Even when downloading from the Google Play Store you need to be careful. Check the permissions the app asks for. Often, apps that include malware will ask for a lot of permissions so that they can quickly gain control of all of your phone’s data.

  1. Settings

Google includes numerous settings in the Android operating system that can prevent malicious attacks. Devices running Android 2.2 or higher, which essentially means nearly all Android devices, have access to Google’s malware scanner. Prior to installing an application, you downloaded outside of the Play store, Google will scan the app and warn you of any potential threats.

  1. Software updates

While this may not be an option for most users, if there is an update for your device make sure you download and install it. Manufacturers, carriers, and Google are constantly pushing out updates with bug fixes, enhancements, and new features that can make your device more secure.

  1. Antivirus apps

The Google Play store is also home to hundreds of antivirus apps that can offer an extra layer of protection. Companies like Avast, AVG, BitDefender, Kaspersky, Sophos, Symantec (Norton), and TrendMicro have long and established histories as some of the most trusted brands in the industry.

  1. Back up your data

Keep your device backed up. You can do this:

  • On your computer.
  • Using a cloud based back up service like Google Drive.
  • On a portable hard disk like a USB pen drive.

Tips on Android ransomware removal

The instructions provided below should help you to remove Android ransomware as well:

Reboot your phone into Safe Mode:

  • Find the power button and then press it for a few seconds until you see a menu. Click Power off.
  • Once you receive a dialog window that suggests you to reboot your Android to Safe Mode, select this option and press OK.
  • If this did not work for you, just turn off your device and then turn it on. Once it becomes active, try pressing and holding Menu, Volume Down, Volume Up or both these buttons together to see Safe Mode.

Uninstall malicious and/or any suspicious and unknown apps:

  • When in Safe Mode, go to Settings. Then, click on Apps or Application manager (this may differ depending on your device).
  • Here, look for the previously-mentioned suspicious app(s) and uninstall them all.

Modern Malware threats are evolving all the time but taking these steps will make it much harder for hackers to gain control of your data. Most of the time cyber criminals are looking to take advantage of silly mistakes that people are make every day. Stay vigilant and 99% of the time you’ll stay safe!

Stand Mixer – Should You Get One?

If you're reading this article, chances are you think you may need a stand mixer. If you are asking yourself this question, my answer would be "YES! Go for it right now!" However, the more people I talk with about the subject of mixers, the more I feel as if people may be wrong in regards to their needs, versus their wants.

A stand mixer is a great beautiful shiny appliance that you can proudly display on your countertop, but how often do you feel you would use it?

  • Once a day?
  • Once a month?
  • Once a year?

Make sure to honestly ask yourself what use you will make of the stand mixer. Are you an occasional home cook who makes simple cakes and light batters, or are you more of a hardcore maniac in the kitchen who loves to dabble in the most crazy and dessert cookie and bread doughs?

These questions will also provide a partial answer to another question, should you get a blender, food processor or maybe even a simple stick blender.

I am a cook myself, and at the beginning of my home baking career I would knead all sorts of breads by hand, which was a tiring and demanding (not to mention time consuming) task. After about a year of this manual labor and scrounging up savings, I was able to purchase my first real stand mixer, and it totally changed the way I worked. From being able to handle only 1 or 2 doughs per day, I scaled to making up to 6 per day, which resulted in me opening a small home bakery, which without a stand mixer, really would not have been possible at all. I spent less time working and slaving, and could relax a lot more, all thanks to this wonderful device.

This is an example of my personal experience, what is yours? As previously mentioned, you may think you want a stand mixer, but in reality you need something else. For example, whipping up egg whites to make beautiful meringues can just as easily be complimented with a hand beater, which usually sell for about $ 20. Same goes for whipping cream. A simple cheap device will get the results you want.

If you need to chop up vegetables or fruits in large quantities, you should look into food processors, although some stand mixer brands sell attachment packages that could do all the things a food processor does, these packs may cost the same as a stand-alone food processor, which can also knead dough, if you are into baking or pastry making.

In summary, make sure if you are going to spend the kind of money a quality stand mixer costs, be positive that you will at least get a decent return on investment, not necessarily moneywise, but at the very least time and enjoyment wise.

What Causes Runtime Error 6?

Runtime error 6 is an “overflow” problem that may happen for one of a handful of reasons.

Runtime error 6 can occur when data gets too big for its britches.

This “overflow” problem can happen when, somewhere along the way, data has been entered that is too big for its data field. What does this mean in plain English?

Let’s say you’re working with Microsoft Access (a database program). You have to put information into various fields (boxes), when some of these boxes are pre-set to only accept certain values. (This can be arranged for a variety of reasons; there is no need to go into the specifics here, as it would require several articles!)

If one of these fields is pre-set to accept values of only 0-255, you’d cause an overflow error if you accidentally entered, say, 377.

Now of course you wouldn’t do this. However, sometimes programmers make mistakes. Sometimes a program must generate a random variable and it could be that the parameters on the generator are too wide (it generates larger numbers than it should).

Nevertheless, sometimes this doesn’t happen until it’s a bit too late. That’s why searching for updates, patches, and new versions/upgrades to your software is often a solution to this problem.

Runtime error 6 occurs with Microsoft Site Server 3.0.

Microsoft Site Server 3.0 is an example of how this kind of error may occasionally occur in even the most tested and professional software. Fortunately, this is one instance of runtime error 6 that can be easily cured. Microsoft support currently offers help with this error.

What else can cause an overflow problem?

Usually, the problem with this error comes from a mistake in programming. It can also come from your registry.

The Windows registry is a directory of program files that all the programs on your computer use. It directs functions to connect with their proper compliments in other programs and hardware.

Without it, your word processor would have to search your entire computer for the printer jack, every time you wanted to print a document. It would also have to search your entire computer for the keyboard, screen, and supporting software every time you started it up!

This would leave your computer unable to run more than a handful of programs at any one time–and even those would run slowly.

Registries can become cluttered over time through no fault of yours. They can also become damaged by spyware and viruses – problems that anti-virus programs don’t typically fix. You can help avoid this by learning more about runtime error 6 and other registry issues.

James Bond's Secret Lair – The World's Coolest Data Center

Data centers have never been exciting places. That is, until now. Its official, the coolest data center in the world is the Pionen, located in 100 feet below the bedrock in Stockholm, Sweden. Originally built as a nuclear bunker used during wartimes, it's now the home of a space-age, Bond-worthy data center.

Instead of focusing on hardware and servers, the designers of this ultra high-tech data center decided to focus on humans, making it a hip and fun place to work. The center features greenhouses, waterfalls, German submarine engines, simulated daylight and it can withstand a direct hit from a hydrogen bomb.

Design Straight Out of the Movies

The location of the facility was the inspiration for the unique design. Building a data center in an old nuclear bunker claims something out of the ordinary and a boring design would not do. To find inspiration for the center, the designers turned to science fiction movies like Logan's Run, Silent Running and Star Wars: The Empire Strikes Back. Additionally, the James Bond movies were a huge inspiration for the design. The designer even wanted to get a white cat, but realized that would be going a bit too far.

Word of Mouth Marketing

One of the hidden benefits for such an intriguing and interesting design is the word of mouth marketing it automatically produces. The space-age design, waterfalls, greenhouses, artificial sunlight and smoke machines make the data center stand out. Since collocation is one of the services they offer, customers frequently visit the facility. When something is this unique customers are sure to share what they saw with their friends and business associates. Something like that can not be ignored. Other companies will want to check it out and see what's so special about the center and voila, they have another customer.

Space-Age Features

But it's not just design and no substance. In fact the data center is just as high-tech as it is aesthetically pleasing.

o Located in a nuclear bunker- the data center is located at the site of an original nuclear bunker from the Cold War. It has also kept the original name: Pionen White Mountains

o Bomb Proof- located 100ft underground and in an original bomb Shelter, no hydrogen bomb is going to destroy these servers. It was built to be secure and protect soldiers in case of an attack. No longer needed for these purposes, it now protects servers … even from a nuclear attack.

o Triple Redundancy Internet- Losing internet connection is not a concern in this facility. Even though it's located deep inside the mountains, there are both fiber and copper wires running into the facility through the mountains from three different directions.

o Cooling- The facility uses Baltimore Aircoil fans to cool the facility to the effect of 1.5 megawatts. This is enough cooling to cool several hundred servers.

o Houses Sweden's largest ISP- this center is home to the NOC for all of Bahnhof's operations. This is the largest ISP in Sweden, with five locations- of which, Pionen is the largest. Additionally the data center is a colocation facility so you can put your servers there if you want.

This data center is by far the world's coolest data center and describes its title. It's tough competition for anyone to outdo Pionen, but if anyone is up to the challenge, the world could use more cool data centers.
