Things about HTML5 that You Should Know


HTML is one of the most successful platforms and the secret behind the successful story of HTML is because it has been synonymous with web page and application development during the exponential growth of the internet. Besides, it is a tried and true method for many web developers which is in recent years. Even though there will be many new development tools, but traditional desktop applications will continue to use HTML with few to no drawbacks. However, with so many new platforms out there,  there is a possibility of that HTML will be changed with Qt. So, discover more explanation about HTML and Qt by reading the points below.

Is there any Drawbacks of Using HTML?

As we know that smartphone has been more popular than desktop, in fact many applications are build for a wide range of shapes and sizes – traditional desktop applications, web applications running on any device with a browser, mobile apps, embedded systems, Internet of things (IoT) devices, and more.

Unfortunately, HTML was never intended for embedded systems and therefore it has shortcomings, as opposed to using other development approaches and native languages. Moreover, when choosing HTML5 you need to choose a JavaScript framework which can be troublesome when there will be a plethora of other JavaScript frameworks to choose from.

What are the Benefits of Using Qt vs. HTML?

After explaining about HTML, let’s see other platform which might offer the same or more benefits, such as Qt. Qt is a cross-platform C++ development framework and includes both libraries and tooling for creating complete applications and user interfaces. The declarative QML language designed is used as one of Qt’s design to let developers use one codebase to create high performance and fluid UIs for all their desktop, mobile and embedded devices. With ML, you can create intuitive and ready-made controls, such as buttons, dials, and switches. In this way, you can easily drag and drop on your canvas to make rapid prototypes.

All of the benefits above have made Qt’s QML have gained a substantial market share in the web development coding languages.

What are the scenarios in which it makes more sense to use Qt instead of HTML? What about vice versa?

The increase in embedded devices lends itself to Qt with the exponential growth. In fact, many believe that QML and Qt may be a better choice for embedded development since they are designed to get the most out of limited resources. On the other hand, HTML is more suitable to be used on the web and is easily deployable across desktop and mobile platforms. Furthermore, as many developers are more familiar with HTML in these use cases, then it makes sense to use HTML, especially if your developers do not know C++. Above all, Qt performs better in terms of responsiveness, start-up time, and most importantly it supports a wide range of operating systems and the overall user experience.

So, Does Qt have a realistic chance of unseating HTML as the programming language of choice?

Many developers are debating whether QML could actually replace HTML as a web language. In terms of performance aspect, the possibility is high, but from a practical standpoint, you would need Google to change their approach.

No matter what, when it comes to the development of web applications and pages, HTML will always be a popular programming language. However, as the world is getting mobile, Qt has become a very competitive alternative to HTML, especially when it comes to embedded development. This makes wider options for web developers to choose from the best suit their specific needs.

3 Techniques that Minimize Downtime


Since users keep on expecting a stable and reliable service, many web developers and system admin attempt to create infrastructures that are more reliable and able to minimize downtime. In fact, minimizing downtime is necessary for increasing customer satisfaction and decreasing support request. Below, we provide you with three areas that are crucial when it comes to downtime and we also offer some improvements that you can apply on them. Check this out!

  1. Monitoring and Alerts

Nothing works better than properly monitoring your infrastructure. In this way, you can discover any issues before they really appear and affect your customers.  Furthermore, monitoring infrastructure will also aggregate and retain a record of stats such as application performance metrics, and system resource utilization. So, the main purpose is to look for anything weird.

Usually a client is interacted on each host that collects metrics for monitoring, and then reports back to a central server. These metrics will be stored in a database and available for many services like searching, alerting, and graphing. Fortunately, there is software that can help you monitor your infrastructure, such as:

  • Graphite

Graphite provides an API that has the support of dozens of applications and programming languages.  On the other hand, metrics are pushed, stored, and graphed in the central Graphite installation.

  • Prometheus

To pull data from a variety of community supported and official clients, you can use Prometheus. It has an alerting system that is built-in and is highly scale able. Besides, it comes with client libraries for several programming languages.

  1. Software Deployment Improvement

Believe it or not, software deployment strategies are one area that plays an important role on your downtime. Unfortunately, many people often overlook it.

Bear in mind that having a complex deployment process will result in the production environment leaving the development environment behind. This can cause any risky software releases since every deployment is a much larger set of changes that naturally brings a much higher risk of problem arising. No wonder this process can easily lead to numerous bugs that can slow down development and cause the unavailability of resources.

Therefore, the best solution for this situation is to set up some up-front planning. In order to sync your production environment with your development environment, you have to figure out a strategy that allows you to automate the workflow, code integration, deployment, and testing.

Here are some best practices regarding the continuous integration and delivery (CI/CD) and testing the software that help you start automating deployments:

  • Maintaining a Single Repository

To make sure that every person on the development team works on the same code and can test their changes easily, you can maintain a single repository.

  • Automating Testing and Build Processes

Don’t forget to automate your development and testing as this will simplify deployment in an environment similar to the final use-case. Besides, you will find it helpful, especially when debugging platform-specific issues.

  1. Implementing High Availability

Another strategy that you can apply to minimize downtime is to use the concept of high availability on the infrastructure which includes principles used in designing resilient and redundant systems.

In this case, the system should be able to detect and analyze the health of the system; it has to know precisely where the error is located. Furthermore, the system must be able to redirect traffic as this can help minimize downtime through reducing interruption.

In order to upgrade to a highly available infrastructure, you have to move to multiple web servers and a load balancer from a single server. The load balancer will show you regular health checks on web servers and routes traffic from those servers that are failing.

Moreover, you can also add resilience and redundancy to increase database resilience using database replication; surely, you will find different database models on different configurations of replication. However, many believe that group replication is the most interesting one, as you can read and write operations on a redundant cluster of servers. In this way, you can detect any failing servers and routing done to prevent downtime.

In conclusion, there are three areas that can lead you to less downtime. If you truly put attention on them, you will have happier clients and of course this will lead you to more revenue.

Practical Guidelines for Using Background Videos on Your Website

When to use background videos on your websites

Nowadays, as a web developer you can use background videos as a great way to improve your website’s look. Moreover, it will also make your videos more enjoyable for visitors. Why? Because good videos can tell the story of a business which each business will surely have their own story that can be told better. So, now you are interested in making background videos, but don’t know how to start? Let us guide you! All you have to do is just keep scrolling and reading.

Best Practices for Adding Background Video

The best reason why you use a background video is because when you use it, your website will look better. Therefore, it is tempting to use any video that looks shiny and interesting without considering its impact. Even though those shiny things may contribute you a lack of minimal advantage, in most cases, they are also the biggest factors that contribute you a slower site. Therefore, trading a static image for video must be worth it.

Below are some things to consider:

  • Select a short length video that loads quickly.
  • Don’t use sound. Sound adds the file size and gives little value.
  • Use a placeholder. This is used to anticipate if the video is stopped or can’t be played.
  • Replace the video with an image for the mobile experience. You can hide the background video element at mobile breakpoints to reveal the background image. Besides, it will give the best experience for the mobile visitor.

When You Shouldn’t Use a Background Video

For some reasons, a background video is good at grabbing attention. However, instead of focusing on your copy, a background video might take up all the attention on them.

On the other hand, if you are too aggressive with your background video, it will overpower the important content. When you want to present complex ideas, like sales-related content to read, videos can be distracting. In terms of explaining, words are still the best. So, don’t run the risk of distracting or losing visitors with a video.

Choose Useful Over Complex

When we are deciding whether or not to add an element, you have to think about the mistakes that it might cause. For instance, it’s easy to make the mistake of thinking you’ll enhance an experience by sprinkling in some fun animations or by hiding and revealing elements, but you might actually be adding an obstacle.

So, the simplest way to keep thing simple is to make it as simple as possible. Your background video should reinforce the content message, eliminate barriers, and complement the rest of your site’s content. In other words, it should bring out the aesthetic element of the website, not stand alone or get in the way.

The Smarts behind Adding a Background Video

A best-case scenario is when background videos supplement or enhance the CTA.

  • Make It Personal

Generally, people want to see other people. It will be easier for users to decide whether they have to take an action, like signing up, making a purchase, or getting in touch once they see a person. Therefore, adding a short video will allow people to visualize themselves working with you.

  • Make it Pop

Most of the case, people want to have text layered on top of the background video, so make sure it’s easy to read throughout the entire video loop. Furthermore, you can aim for a strong light/dark contrast between the background video on the copy.

You can also apply a solid, monochromatic filter on top of the video to ensure full, legible contrast. This technique will not only make this look super professional, but the color contrast also makes the text, form, and landing page CTA look impressive. Other method that you can also try is by including a text shadow, or a semi-opaque color block behind the text.

  • Keep It Short

It is important to keep the video short. Therefore, it is better to make a video with the length no longer than 10 seconds, but make sure that this short, looping video should be enough to get the point across without impacting the load time.

Sometimes, creating a loop can be challenging, the loop will appear out of place or incomplete if the video is too short. On the other hand, if the video is too long, your visitors can easily click away from the site or to another page before the video’s had a chance to do a great thing.

If you can’t produce your own video, you can search for other places to get stock video clip. Double check the copyrights associated with any video before you use it. However, we would recommend you to always produce your own video to make it more personal.

  • Make It Unstoppable

Be confident, as long as you give a good quality and on brand video content, your visitors will likely press play or pause. The best way that you can offer is to play the background videos automatically. This will surely grab the visitor’s attention and keep them interested, as soon as they see the video element.

Don’t Forget the Analytics

It’s important to run a test, such as an A/B test to compare how your page performs with a background video compared with a static image. Just to be safe, you can start by pushing a small portion of your traffic towards the page. However, most usability specialists lean on experience, gut, and personal opinion when deciding what design brings customers satisfaction. This method is, of course, not right as you can use data as a great way to know what your customers actually think, as opposed to what they say they think.

So, have you tried background video in your website? It’s worth trying the method that will surely make your site look more sophisticated and smart. Good Luck!
