Why Are Challenges Important for the Developers?

Mobile app development challenges, although painfully unpleasant and almost impossible to achieve, are important because their implementation allows the developer to grow and develop their skills. Overcoming difficulties, the developer gains experience and when repeating such a situation, he will know what to do and will cope with it easier.

1. Device Compatibility and Screen Size

A conscientious developer wants the application to look good at least on current smartphones, and fulfilling this is a challenge. There are thousands of smartphones, and they differ not only in resolution, but also in proportions and pixel density. And there are also features of specific models, such as a notch at the top of the display on the iPhone X.

In addition, there are both “natural” Android (for example, from Samsung or Google), and smartphones that use the Android kernel + their interface wrapper (for example, Xiaomi). Somewhere the navigation keys are hardware, somewhere they are virtual, and somewhere they are not at all.

Therefore, do not think that adapting a design for all this variety is an easy task. For each permission you need:

  • stretch the interface and content to fit the screen;
  • scale images without loss of quality;
  • scale the controls so that they are comfortable to use;
  • maintain the size of fonts so that the texts are readable;
  • avoid layering of elements;
  • prevent target buttons from going off-screen;
  • consider the behavior of the onscreen keyboard.

And for some applications, this work doubles if you need to maintain horizontal and vertical screen orientations. Next, you will meet with challenges in mobile application testing.

Besides all this, there are also tablets. You may not think about them, but tablet owners will definitely think about you. This Web and mobile development company-Dataxdev certainly knows how to cope with any problems and make a quality product

2. Mobile App Security

If you have paid content and a little popularity, a hacked version of your application will most likely appear on the relevant sites. Anyone can download and use it for free. But this is a marginal way, most users will not bother so much, so I would not worry too much about it.

More arrogant ill-wishers can hack your application right in the store. They say it’s especially easy to do this on Google Play. So here you’ll meet the challenges of mobile computing.

A separate topic is the storage of user data. It’s not for nothing that we constantly hear about scandals with their leakage. I think small applications are out of the risk zone. But it is better to follow some minimum rules like “do not store user data in clear text”. A robot with application protection needs to be done as efficiently as possible in order to close all loopholes for attackers.

3. Cross Platform Compatibility

Even before writing the first line of code, you will face a fateful choice: should you create an application natively for each platform (iOS / Android) or on a cross-platform framework?

In the first case, you will have to almost double the cost of development and support, in the second, you will become permanently dependent on the chosen framework (its limitations, updates, features).

A lot will depend on this choice, even the difficulty of hiring new developers for the project. And there is no one correct solution – there are pluses and minuses everywhere. This is the challenge. You need to choose the right development path. In the case of a cross-platform path, one must be prepared for difficulties, because the cross-platform development tools are far from ideal.

Conclusion

Sometimes it is the wrong estimate of the complexity of a project that ruins good products. There are many more challenges for developers, but in any case, they are all solvable. Half of them may not touch you at all. But it also happens the other way around, when several risks shoot out at the same time and aggravate each other. Therefore, it is better to take them into account at the early stages of development.

Why You Should Consider a Used or Refurbished Transformer

Published

on

why-you-should-consider-a-used-or-refurbished-transformer

In case you didn’t know, there is a shortage of transformers being caused by a shortage of raw materials. As a result, lead times for obtaining a new transformer are long.

It can take from 30 weeks to well over a year to acquire a new dry type transformer, so if you happen to need one, it’s recommended to buy one as soon as possible.

However, even if you order one now, you’ll still have to wait a while for it to arrive. In the meantime, you might want to consider buying a used or refurbished transformer. You can always resell it when your new transformer arrives.

If you’ve never looked into used and refurbished transformers, here’s why you should make this consideration.

Used transformers can be obtained quickly

If speed is essential for you to get moving, then buying a used transformer will help you get what you need fast. You might not be able to find exactly what you want, but that’s okay because at least you’ll have something while you look for or order the transformer you really want.

Utility companies across the United States are running out of transformers, and even they are having to wait to get new ones. If you can’t wait for your local utility company to get a transformer for you, you’ll have to source it yourself.

If you happen to be under any kind of pressure to install a transformer, time is of the essence, and you’ll be surprised at just how much a used transformer can help.

Used and refurbished transformers are cost-effective

Reports say that new transformers have risen in price by close to five times what they were prior to the shortage, and that’s going to put a dent in your bank account. However, when you buy a used or refurbished transformer, you’ll pay significantly less.

Refurbished transformers can be as good as new

Depending on what manufacturer you buy a refurbished transformer from, it could be as good as new. It all depends on the craftsmanship provided by the manufacturer. Some people don’t refurbish units properly or thoroughly, and others use cheap materials, like thin insulation that wears out too quickly. You want to avoid this situation at all costs because that will only make your transformer fail.

To get a dependable refurbished transformer, research the company you’re considering buying from to make sure they use the right materials and processes to restore their units to fully functioning, long-lasting transformers.

The downside to buying used transformers

Although a reputable manufacturer can refurbish a transformer and make it work like new, the same can’t be said for a used transformer. When you buy used, it’s a gamble and you never know what you’ll get until you have it installed and start using it for a while.

That doesn’t mean all used transformers are bad, but you have to consider why someone would sell a transformer in the first place, especially during a shortage. It’s possible and even likely that most people selling at this time have simply bought a replacement that is an upgrade, but that still means you’ll be getting an older unit.

Even when someone is selling it for honest reasons, you can’t guarantee it will work perfectly for any length of time. And if you don’t open it up to see how it’s insulated, you could end up with an exploded transformer when you least expect.

The downside to buying refurbished transformers

Unlike used transformers, refurbished units aren’t as much of a gamble, but there is a downside. If you have to spend several thousands of dollars on a refurbished transformer, that’s several thousand dollars less that you have to spend on a new transformer when one becomes available.

If you happen to have the extra cash available, get a refurbished unit to use until your new transformer arrives. Then you can sell the refurbished one and recover some of your costs. However, if you don’t have that extra cash flow, then you might be stuck using a refurbished one long-term.

That may or may not turn out well for you, so this is why it’s crucial to always buy from a reputable manufacturer who goes the extra mile to ensure their refurbished units are properly restored.

Don’t put off buying a transformer

If you need a transformer now, don’t put it off by holding out for a new one. If you wait for supply levels to return to normal, you might be waiting a while because experts say the shortage won’t end anytime soon. Get a used or refurbished transformer now, and then sell it after you get the new one you really want.

A Comprehensive Guide to Bubble Chart Design Principles and Best Practices

Published

on

comprehensive-guide-to-bubble-chart-design-principles-and-best-practices

An excellent mode of visualizing data in the digital world, the bubble chart can bring depth to your data-driven stories. Throughout time, experts have developed various design principles and best practices to augment their data storytelling using these multifaceted charts.

In this article, we explore the bubble chart design principles, their relevance, key components, effective strategies for designing, and best practices for enhancing their display.

Understanding Bubble Chart Design Principles

Understanding Bubble Chart Design Principles

Bubble charts, an intriguing variant of the scatter plots, use circles to showcase data in a two-dimensional plot. They incorporate a third data dimension through bubble size, which provides an excellent way to present three variables on a single plot.

A bubble chart is thus a multi-variable graph that might contribute valuable insights into often complex datasets.

The bubble chart’s design principles are based on the fundamentals of visual perception, data visualization, and design aesthetics. Each circle’s size signifies a specific metric, and the spatial positioning of the bubbles gives the other two metrics. Innovation in presentation and accuracy in representation is vital to bubble chart design.

The choice of scale is crucial in bubble charts. To create an accurate and effective chart, it’s important to always bear in mind that our eyes perceive areas and not diameters. Hence the design should cater to this perception.

Irrespective of whether you use bubble charts for academic research or data-driven storytelling, understanding its design principles will significantly improve your presentation and interpretation of data.

Key Components of a Bubble Chart

Key Components of a Bubble Chart

Understanding the key components of a bubble chart not only simplifies its interpretation but also aids in creating effective and accurate charts. Each bubble in the chart is defined by three data points: the X-coordinate, the Y-coordinate, and the size.

With the position along the horizontal and vertical axes, we describe the first two dimensions of the data. These positions often represent specific values for two distinct variables. They commonly show correlations or relationships between these two data points.

Bubble size contributes to the third data dimension. The size of each bubble is determined by the value of the third variable. This adds depth to the data, recommending the magnitude of a specific metric under study.

Color and bubble size, another two components, often function as visual cues, guiding viewers to find meaning in the presented information. Designing an effective bubble chart requires careful planning and execution.

Best Practices for Enhancing Bubble Chart Display

While designing a bubble chart is one thing, continually improving and enhancing its display is another essential aspect. The chart should be straightforward and intuitive to read, decipher, and understand.

To enhance the bubble chart display, consider adjusting the size and color of bubbles for contrast and clarity. Maintain a meaningful pattern or sequence with the display of bubbles for an easier and quicker grasp of information.

Regularly update bubble charts based on new data to maintain relevancy. Ensure simple and uncluttered design to enhance the focus on information and data trends rather than design elements.

Most importantly, always keep your audience in mind. A complicated bubble chart might be great for a data scientist, but it might not be suitable for your clients or the public.

Overall, bubble charts serve as powerful tools for data visualization, provided one understands and follows their design principles and best practices. They display complex and voluminous data while offering easy interpretation and comprehension of the visualized information.

Is There an App to Make Someone Smile?

Published

on

is-there-an-app-to-make-someone-smile

Photos in which people are smiling always evoke a lot of positive emotions. A serious face is not always appropriate, for example, during holidays, you always want to take positive pictures. But there are people whose smiles may appear too constrained or unnatural, and some may even be shy to smile.

If such a person is in a photo, and you want to improve it a bit, you can do it with the help of special applications. We have chosen three of the best ones to tell you how you can do this. By the way, they work on both the Android and iOS operating systems.

Retouchme

A very convenient and user-friendly application that can make even the grumpiest person smile. At the same time, everything will look very natural because a professional retoucher will work on the photo, not artificial intelligence. Using the app is very easy:

  1. Download and open it.
  2. Upload the photo you want to edit.
  3. Select the “Face” section.
  4. Choose the smile adding function.

You’ll have to wait for a while as real people will do the work manually. But the result is worth it – it will look natural, and no one will guess that the photo has been edited. You can see how to edit a smile and learn the functionality of the program at this link: Retouchme.com/service/smile-editor. Now, let’s move on!

YouCam Makeup

This application works on a different principle – based on artificial intelligence. It identifies the boundaries and parts of the face, highlights the lips, and then processes them as needed. You can add a smile to a person’s face with a single click, and the result will be highly expressive. Another option is to use a special slider that allows you to adjust the intensity of the smile.

The app is also convenient because it offers many additional features for photo editing. For example, along with the smile, you can retouch the cheeks to give them a rosy hue, and add a mischievous twinkle to the eyes.

Overall, this app produces a natural result, which is why it’s among the top three that you can easily use for your purposes.

Facelab

Try this app to get the most natural smile that artificial intelligence can create. Here, control is done through a slider, so you can adjust the smile’s intensity yourself. This control is very convenient because you’re not limited to what the app provides; you can fine-tune the result as you like.

This app is also useful because you can simultaneously edit the fullness of the lips, the color of the teeth, and many other details to make the photo look natural and better than the original.

Which one to choose: an app with professional retouchers or AI?

The choice here depends on what’s more important to you. You should choose apps with professional retouchers if you:

  • Want the editing to be completely seamless.
  • Expect a maximally natural result.
  • Want a smile that suits you perfectly and looks organic.

Artificial intelligence has its advantages. You should choose it if speed is important to you (AI processes much faster, and you won’t have to wait) or if you want to have more control over how the smile looks in the photo.

In general, any of these apps will make your life easier if you’re smiling with downturned corners, look sad, or if someone else in the photo doesn’t fit in due to a lack of a smile. You can use them regularly, as they won’t degrade the photo quality, and then share your work with others on social media.
