Is It Necessary to Upgrade to Skype Premium?

Skype is an instant messaging application that can be used to exchange text messages with other people and conduct voice and video calls with them. It is now one of the most widely used messaging app in the world with millions of users. However, people not only use the app for personal purposes but for business purposes as well. This is the main reason why the Skype Premium has been developed so that businessmen who use the software, and some people too, can take advantage of the many features of the Premium app not available in the free version. However, is it really necessary for you to upgrade to the premium version of Skype? Find out by reading the article below.

Total Absence of Advertisements

Perhaps one of the best things about the Skype premium is that there are no more advertisements present unlike the Skype for free. With that, you can focus on using the app itself and there will be no more annoying things ads placed in different parts of the app.

Unlimited Calls to Landlines and Mobiles

Another good thing about the Skype Premium is the ability to make unlimited calls to landlines and mobiles. In the free version of Skype, you need to spend Skype credits to be able to make such calls. However, with the Skype premium, you no longer need to have some Skype credits since you will have unlimited calls to landlines and mobile phones.

A Helpful Support Chat

A helpful support chat is also available in the premium version of the Skype application. Whenever you need to inquire about something or if you need help about something in the app, you can easily consult with the live support chat to help you with your issue. For instance, if you are currently experiencing some problem with using Skype, then the support chat may help you with that.

The Bottom Line

With those features of the premium app being said, you can now evaluate whether or not you will upgrade to the premium version. The bottom line and the recommendation is to upgrade only if you need the features available in the premium version. However, it would not be bad as well if you have some money to spend with in order to upgrade your Skype experience.

In addition, just like in the free version of the Skype software, you may also use the Skype Resolver in the Premium version of Skype. With this tool, you can extract various contact details from your Skype contacts. For instance, using the Skype ID of an individual, you can obtain his or her email address and IP address with the Skype Resolver. This can be really beneficial especially if you need to keep in touch with people not only from Skype but through other means as well. Therefore, you can go beyond Skype to connect with your Skype contacts.

Test Scripting Vs Exploratory Testing

Test Scripting Vs Exploratory Testing

Are you searching for the best way to test your latest software and not sure whether test scripting or exploratory testing fits the bill?

Lately, the latter has become the darling of agile development. However, test scripts have proven their effectiveness over time.

As a software engineer or test manager, it is up to you to compare the two and decide.

We’ve gone ahead and done the work for you. Read on for a concise comparison of these two popular methods to help you decide which is best for you.

Test Scripting and Exploratory Testing – the Basics

A test script is a complex set of instructions that testers must follow to see if the desired outcome is achieved.

Provided intensive preparation is done, this method should cover all the bases when it comes to uncovering software errors. It is so detailed that you could even get a machine to do it for you.

What is exploratory testing used for then? This procedure relies on the experience and intuition of the testers to root out errors for themselves. They are not provided with the expected outcomes in advance.

In this way, off script testing has the benefit of creating scenarios that the script writer may have overlooked.

Comparative studies have proven that exploratory testing exposes more errors faster than test scripting does.

Blow by Blow Comparison

The following is revealed when taking the most important testing factors into account:

Domain Knowledge

This is imperative for effective exploratory testing. This is not a factor when the rigid procedures of scripted testing are employed.

Test dependencies are better managed with test scripting. Unscripted testing relies on the skill sets of the testers to manage these.

A high level of documentation and a significant lead time are required for scripted tests. Exploratory testing requires neither, provided domain knowledge is adequate.

When it comes to efficiency, it is time-consuming and laborious to create detailed scripts. There is no comparison with the speedy off-the-cuff nature of unscripted testing.

Exploratory testing

This provides no clear and measurable coverage. It relies on the testers to document their findings. Scripted tests involve detailed, formal record keeping.

Scripted tests formally verify the results against set specifications. Unscripted testing is based on the tester’s expectations and domain knowledge.

High-risk areas can be covered in minute detail with scripted tests. There is a chance these may be overlooked by exploratory testers.

Tests can be reproduced accurately with test scripting. Only defects can be reproduced with the less formal approach.

The Winner Is?

When deadlines are looming and you need to test the major aspects of your software quickly, exploratory testing is the answer. It is a cost effective method if your project is fairly straightforward, such as a simple informational website.

Often it is a good idea to do complex testing at first and then follow up with unscripted testing. Exploratory testing closely mimics end-user interaction with the software. It also allows for the vagaries of human interaction.

As for who wins? You do. You have the benefit of selecting from two proven tactics for each stage of your software development.

Image Compression for Android Developers

Image Compression for Android Developers

Being Android Developer with every release of the app update, the app size was getting increasing significantly and this was a major concern for me.

I always wanted to minify the app size and make sure the app is delivered at its best level.

Thanks to android studio to come up with the full flexed support of vector drawables with Android 5.0. Also there is a support library 23.4.0 which gives a support for vector drawable from API 7.

Best Solution

Preferred solution is to use ImageZipper – Android Image Compression Librarywhich is an image compression library which helps you to compress your images both in default and custom way. It allows you to control you the width, height, format, orientation and quality of Image. It ease out the task to send images to the server.

I would to share the other way, i keep the images in the app compressed.

  1. Check if you could covert your image to vector drawable. If yes then don’t think of converting it to the other type, go for it. Here the advantage is you don’t have to create different icons for different dpi’s. One vector drawable will work for all dpi devices. Convert the svg file to vector drawable using vector asset studio in simple steps.
  2. WebP is supported by your app? WebP is supported from Android 4.0+ version. If yes the go for non-transparent WebP images from 4.0+ and transparent WebP images are supported 4.2.1+. This format is 20% to 30% smaller in size compared to PNG format.
  3. Use PNG when image needs transparency. this format is best to deal with transparent images. Optimize png image using following options:

4. Go for JPEG format, if you image is of complex format. But make sure you don’t forget to optimize the image size using following options

  • Use online tools to optimize jpg images. some of the tools are JPEGMinipackJPGImageMagick. This tools reduce the image size significantly.
  • Reduce colors.

Hope, this easy steps will help you reduce your images size and will significantly reduce the app size 🙂

Google Introducing Android 8.0 Oreo

The search giant continues its tradition of naming releases after confectionery, using a brand name for the second time.

Google’s next version of Android is called Oreo and is coming to smartphones and tablets in the near future.

Google announced that it has pushed the final version of Android 8 Oreo out to the Android Open Source Project, the underlying software that the Android loaded on smartphones and other devices is built on. Google’s Pixel and Nexus handsets will also soon see the update, with beta programme participants receiving it first.

The new operating system received its first stable release on Monday 21 August, but will be more consistently released in the autumn, most likely after Google releases its new Pixel phone in October.

“One key change in Android Oreo is in the architecture: to make it easier in the future for phone manufacturers to make their changes, but still push out new versions of the operating system to users.

“That’s probably the most significant change.”

Build Your Own Ransomware Virus

Hi guys, I recently wrote an article for my blog about a new service that lets you create your own ransomware. Due to Cybrary policies, this article was rejected from Cybrary OP3N, but I still think it would be interesting to some people, so I will write about it here.

A new type of ransomware is being freely distributed on the Deep Web, but this is not normal ransomware. This RaaS (ransomware as a service) is a new form of cybercrime that works by malware authors distributing the ransomware builder, and then taking a cut of the ransoms it generates. Anyone, no matter how computer savvy they are, can launch a fully-functional ransomware campaign to unsuspecting victims.

Atom Ransomware, formerly called Shark, first started popping up on the Internet in mid July 2016. You can download it through their professional looking website that gives you step by step instructions on how to set it up and start infecting people. The creators claim that it is undetectable by AV software, supports multiple languages, and uses a strong but fast encryption algorithm.

After you download the Atom payload builder, you can specify the bitcoin address to send the ransom to, the directories to infect, the file formats you wish to lock, the price of the ransom, and varying prices for different countries. All of this you can do with no technical knowledge. If you can type on a computer, you can use Atom to create ransomware. The payments are supposedly automated; sending the money first to the malware developers who take a 20% cut, then they send the other 80% to your bitcoin address that you supplied. After it encrypts the files with a .locked extension, it creates an encryption key like every other ransomware. After that, it locks the screen prompting for a password to unlock the files.

Could this be the start of a new cybercrime service? Could this be the future of ransomware?

It’s hard to say what the future will look like in this ever-changing industry, but it very well may play a big part in the future of cybercrime. With open source ransomware such as HiddenTear, and the DIY ransomware builders already out there like Tox, ransomware is becoming easier and easier to make. And with all the work it takes to launch a ransomware campaign, why distribute your ransomware yourself? Atom has a great business model so far. Easily make the ransomware, have other people distribute it, and take 20% of the profits. 20% might not sound like a lot, but say someone customizes Atom to sell for $100 to unlock the files. If that person infects one other person, that’s still $20; and it will only continue to grow as more and more people create new Atom ‘strains.’ This is highly illegal and extremely unethical, but you have to admit, it’s a great idea, and will surely be a huge money maker for them.

The one problem that may arise is that there’s no way for Atom users to guarantee that they will get the 80%. Could this just be a huge scam to get people to spread Atom? Could the developers just take the whole ransom and walk away? Let me know what you think in the comments below!

In the future I hope to be analyzing Atom more in depth, as it seems like a very cool project, and I’d love to know more about how it works internally.
