SQLite is an often overlooked flavor of SQL engines. Some have suggested it is the most prolific SQL engine in existence due to its highly flexible nature and ability to run on almost any platform with limited resources. Unlike other SQL engines like MySQL, PostgreSQL, MSSQL, or Oracle, SQLite runs without a server. SQLite does not rely on a data directory or a constantly running daemon: a database is encapsulated in a single file.

SQLite and iMessage

iMessage is one of the most popular messaging platforms today, largely because it is built into iOS and Mac devices. Since its release, it has evolved significantly. But, at its core, it is simply an instant messaging platform. iMessage uses SQLite in the background to store relational data about messages, conversations, and their participants.

Alongside HTML and CSS, JavaScript makes up the holy trinity of front-end technologies.

JavaScript is cross-platform and object-orientated. You can use it for everything from simple animation to complex server-side operations. JavaScript fell out of fashion after its initial release; however, it has grown to dominate web coding in the last decade.

But how much do you actually know about JavaScript? Let’s find out…

Micro-interactions effectively communicate brand identity and ethos while strengthening ties with the customer. These habit-forming tools make for a fun and seamless user experience. Facebook’s ‘likes’ and Tinder’s ‘swipes’ are two classic examples. 

Micro-interactions originated with the need to guide customers who had hit a snag while using a service or a product. The goal was to ease customers into being more product-savvy via subtle reassurance and feedback. Micro-interactions are now employed by everything from washing machines, to coffee makers.

Along with feedback, prompts, and recommendations, they can also present customers with an appealing visual reward upon finishing a task. When used optimally, micro-interactions drastically enhance the navigation and simplify how users interact with sites and apps.

How Micro-Interactions Work

Here are the four structural elements to a simple micro-interaction: triggers, rules, feedback, and loops. Every micro-interaction has a significant component to organize the operational cycle. It lets you control feedback and runs, so the users understand the consequences of their performance and feel motivated to follow through.

Triggers

This feature begins micro-interactions of both the user-initiated (prompted by user) and system-initiated (driven by the system) kind. For example, a click, scroll, swipe, tap, and pull are common triggers that users carry out. So making a payment, booking a cab, and clicking or tapping on the hamburger menu all fall under this category. On the flip side, the user’s alert prompt upon entering a wrong password is a classic system-generated trigger. 

Rules

This element determines what happens after the user sets a prompt into motion via tapping, clicking, scrolling, or swiping. Rules refer to the fact that apps decide the triggers that users employ — Tinder’s ‘swipe’ feature illustrates this point. These rules gradually become a habit-forming action that users get accustomed to while regularly engaging with an app.

Feedback

During this process stage, the system informs the user via auditory, visual, or haptic cues. It engages the users and encourages them to proceed further in their process. For example, the progress bar of a download, the visual representation of steps cleared in a circle, or the visual, aural, and tactile indication upon the success or failure of payment are all a part of the feedback mechanism.

Loop/Modes

This final stage entails tiny meta-rules of the process and determines the frequency and duration. A classic example from an ecommerce app is the ‘Buy Now’ transformed to ‘Buy Another’ Before the user loses interest in the app, the app typically uses such a loop to get them to re-engage with the app. 

How to Use Micro-Interactions

We’ve established that micro-interactions are fabulous, but not every UX interaction on your app or site needs one throughout the wireframe. Overusing this tool could saturate the overall creative experience your design may want to offer. Worse, it might even end up confusing the information hierarchy. It undermines the design and unbalances the user experience of discomfort and irritability. So it’s crucial to know when exactly to use them.

Let’s find out how few quick tips on micro-interactions can elevate and humanize your mobile user experience:

  • Swipe right or left: A signature move made entirely on swiping micro-interaction featured in the famous Tinder app. Swiping is an easier action than clicking or tapping.
  • Call-to-action:  As part of the last step during payment or order, place a ‘Confirm Order’ or ‘Book Now’ prompt, which gives the task a sense of urgency. As a result, having acted on it feels like a minor achievement. 
  • System status: Your app user wants to know what’s happening. System status lets them know they are moving in the right direction and helps avoid confusion. Sometimes, users even run out of patience while uploading a picture, downloading a file, or filling up the registration form.
  • Classic notifications: Users need a quick reminder of products selected/wishlist in their abandoned cart with a reduced attention span. A simple notification can nudge them toward finalizing the purchase. 
  • Button animation: Animated buttons are not only cute, but they also help users navigate the mobile app swiftly. Try out attractive colors, fonts, sizes, shapes, and clipart elements corresponding to the animation and create that cool button to pop up when tapped or hovered on. 
  • Animated text inputs:  A simple process of a likable element like zooming in while entering data into a form or filling up card details for payment can enhance the user experience.
  • Reward an achievement:  Especially true for educational and health apps, micro-interactions celebrating big and small milestones with a badge or a compliment of encouragement can strengthen a user’s engagement with the app. 

Benefits of Micro-Interactions

  • Brand communication: A successful brand ensures that the transmission to the buyer is engaging, positive, and hassle-free. When micro-interactions show a process status clearly, it creates and reinforces a positive image for your brand.
  • Higher user engagement: Experts say micro-interactions engage users better. These tiny elements subconsciously create the urge to keep interacting with your app. For example, each push or nudge notification acts toward redirecting your customers back to your app.
  • Enhanced user experience: From shopping to banking to traveling to learning to staying healthy, there’s an app for everything. A wide range of activities elevates the overall user experience and stays ahead in the game. Micro-interactions can work that magic for your brand. 
  • Prompt feedback: It’s frustrating not to know what’s happening behind the blank screen, especially during a purchase. Instant feedback via visual, sound, or vibrating notifications makes for a pleasant user experience. 
  • Visual harmony: Micro-interactions initiated even with a tap, swipe, typing, or scrolling are all a part of the UX design’s overall appeal. The trick is to keep all the interface elements in perfect sync with the app’s visual features.

Micro-Interaction Best Practices

Here are a few basic principles you should follow when you introduce a micro-interaction to the user experience.

1. Keep it simple, stupid (KISS)

KISS is a famous design principle that becomes even more important in the case of micro-interactions. The goal is to make the user journey delightful and not be a distraction.

2. Keep it Short

It has ‘micro’ in the name itself. But, again, micro-interactions aren’t supposed to be show stars, and a lengthy micro-interaction only distracts the user. 

3. Pick the Right Place

You should always consider the options carefully before choosing the spot for any micro-interaction. The widely used user-interaction designs are popular for a reason. Many people have already approved them, so you can safely continue with them. The use of micro-interaction should also sit well with your brand image. 

See also if the placement of a micro-interaction is reaching your ideal customer or not. And even consider whether you need a micro-interaction to begin with. 

And That’s a Wrap!

As UX designers, we can profoundly impact the overall design of sites and apps, the user’s journey, their interactions with our product/service, their connection with the brand, and the ease of doing a transaction.

We want customers to connect to our brand, love our products, and experience our exceptional customer service. But most of all, we want to earn their trust and loyalty.

Sometimes on Linux/UNIX computers, you will want to do a search for any files containing a particular string within it. This can be particularly useful when searching for specific things for a CI/CD pipeline.

On Linux or Mac, if we want to search a set of files for a specific string in a terminal, we use the grep.

Today, more than 100 billion searches are conducted every month on the Google search engine alone. Search engine users conduct searches for several reasons including the foundational conversion of information into action. An action could be a decision to purchase, consume information for decision-making, or seek a better understanding of an issue or topic among others. Search engines make information available at our fingertips right whenever we need it. 

In this era of big data, search solutions are useful not only for popular search engines like Google, Yahoo, and Bing but also for enterprises for monitoring and managing the growing volumes of data in their databases to enhance operational efficiency. The enterprise search industry has grown remarkably and is expected to be worth $8.90 billion by 2024.

For demos, system tests, and other purposes, it is good to have a way to easily produce realistic data at scale utilizing a schema of our own choice.

Fortunately, there is a great library for Python called Faker that lets us build synthetic data for tests. With a simple loop and a Pulsar produce call, we can send messages to topics at scale.

Stream-Aligned and Platform Teams

The 2021 State of DevOps report identifies two types of teams as the way high-maturity teams organize themselves: stream-aligned teams and platform teams. The idea of a « platform » or « internal developer platform » is fundamental to GitOps. While a GitOps pipeline begins with committing code to a Git repository, it is made possible by a platform that paves the way for that new code to move in an automated way from the repository to a production environment.

The platform is how the Ops team provisions resources such as cloud services, storage, service meshes, and security and monitoring tools in a ready-made template. These templates are created even before they are needed and made available to any developer within the organization. The big shift due to this is that developers need not raise a ticket for the resources they need: they can pick a ready-made template and deploy their code in a matter of minutes. From the Ops side, they have peace of mind knowing they have configured this template and that it follows security protocol by default. It does not require developers to separately configure security for deployments.

Often times when we are creating an application, the data we use determines what we show to the user. For example, in a to-do application, we may have multiple to-do list items. In Vue, it is easy to display multiple data points through the v-for attribute in our Vue templates.

How To Use V-for in Vue

Let’s suppose we have some data we are storing on a single page component. Our .vue document looks a bit like this:
