Microservices have crafted highly flexible and adaptable IT infrastructures. Microservices is a unique software development approach that concentrates on creating single-function modules that work jointly to execute the same tasks. It enables you to alter only one service, without modifying the rest of the infrastructure. In simple words, one can easily deploy and change every service without affecting the functional facets of other applications or services. Instead of following an old monolithic architecture (sole app with manifold functions), testers and developers use this microservice approach to build independent modules for every function.

However, the microservice architecture can also make an app extra complicated, particularly when we add several functionalities. Likewise, testing the combined functionality of numerous services is a lot more complicated due to the distributed nature of the app. As microservices follow a dissimilar architecture, we also require an exceptional strategy for testing microservices. In this article, we will explore different tools for testing microservice applications. Testing microservices can assist us in eradicating several issues by avoiding a domino effect.

Pintr New Image

Pinter New Image turns photos into funky and fun line images. Upload an image with plenty of contrast, use the controls to set the look you want to achieve, and download. The new images are available as PNG or SVG. Maybe use it to create your next profile photos for social media or a nifty avatar.

Terms & Conditions Apply

Terms & Conditions Apply is a game that explains all those little pop-ups that you accept to enter and interact with websites. You are tasked with a mission to start the game: Do not accept terms and conditions, say no to notifications, and opt-out of cookies. Can you do it?

Khroma

Khroma uses artificial intelligence (via personalized algorithm) to learn what colors you love and create palettes for you to discover, search, and save for use in projects. The beta tool is easy to get started with, although you do have a little color-picking homework to get started.

6 WebTools

Mmm

Mmm is a different type of website builder. The tool, which is still in alpha, allows users to create drag and drop websites in a simple manner. It works almost like making a digital collage. Users can get a custom URL, and every page is responsive. The interface is designed so that you can even build yours on a phone. And here’s the other feature – they encourage messy designs.

LightGallery

LightGallery is a lightweight, modular, JavaScript image and video lightbox gallery plugin. It works with React.js, Vue.js, Angular, and TypeScript. It includes plenty of demos and documentation to help you make the most of this gallery tool.

Vandal

You can expose your app to the public by setting up a Kubernetes LoadBalancer service in your IBM Cloud Kubernetes Service cluster. When you expose your app, a Load Balancer for VPC that routes requests to your app is automatically created for you in your VPC outside of your cluster.

In this post, you will provision an IBM Cloud Kubernetes Service cluster spanning two private subnets (each subnet in a different zone), deploy an application using a container image stored in an IBM Cloud Container Registry and expose the app via a VPC load balancer deployed to a public subnet in a different zone. Sound complex? Don’t worry, you will provision and deploy the app using Terraform scripts.

Editor’s note: This interview with David Linthicum was recorded for Coding Over Cocktails — a podcast by TORO Cloud.

The cloud has changed the way enterprises provision and deploy IT. Although dealing with databases, storage, compute cycles, and other platforms that can be leveraged on-premise still have their place, the cloud has provided a new consumption model that is continuously evolving.

Gartner predicts that by 2023, over 50% of medium to large enterprises will have adopted a Low-code/No-code application as part of their platform development.
The proliferation of Low-code/No-code tooling can be partially attributed to the COVID-19 pandemic, which has put pressure on businesses around the world to rapidly implement digital solutions. However, adoption of these tools — while indeed accelerated by the pandemic — would have occurred either way.
Even before the pandemic, the largest, richest companies had already formed an oligopsony around the best tech talent and most advanced development tools. Low-Code/No-code, therefore, is an attractive solution for small and mid-sized organizations to level the playing field, and it does so by giving these smaller players the power to do more with their existing resources.
While these benefits are often realized in the short term, the long-term effect of these tools is often shockingly different. The promise of faster and cheaper delivery is the catch — or lure — inside this organizational mousetrap, whereas backlogs, vendor contracts, technical debts, and constant updates are the hammer.
So, what exactly is the No-Code trap, and how can we avoid it?

What is a No-Code Tool?

First, let’s make sure we clear up any confusion regarding naming. So far I have referred Low-Code and No-Code as if they were one term. It’s certainly easy to confuse them — even large analyst firms seem to have a hard time differentiating between the two — and in the broader context of this article, both can lead to the same set of development pitfalls.
Under the magnifying glass, however, there are lots of small details and capabilities that differentiate Low-code and No-code solutions. Most of them aren’t apparent at the UI level, leading to much of the confusion between where the two come from.
In this section, I will spend a little bit of time exploring the important differences between those two, but only to show that when it comes to the central premise of this article they are virtually equivalent.

Low-Code vs. No-Code Tools

The goal behind Low-Code is to minimize the amount of coding necessary for complex tasks through a visual interface (such as Drag ‘N’ Drop) that integrates existing blocks of code into a workflow.
Skilled professionals have the potential to work smarter and faster with Low-Code tools because repetitive coding or duplicating work is streamlined. Through this, they can spend less time on the 80% of work that builds the foundation and focuses more on optimizing the 20% that makes it different. It, therefore, takes on the role of an entry-level employee doing the grunt work for more senior developers/engineers.
No-Code has a very similar look and feel to Low-Code, but is different in one very important dimension. Where Low-Code is meant to optimize the productivity of developers or engineers that already know how to code (even if just a little), No-Code is built for business and product managers that may not know any actual programming languages. It is meant to equip non-technical workers with the tools they need to create applications without formal development training.
No-Code applications need to be self-contained and everything the No-Code vendor thinks the user may need is already built into the tool.
As a result, No-Code applications create a lot of restrictions for the long-term in exchange for quick results in the short-term. This is a great example of a ‘deliberate-prudent’ scenario in the context of the Technical Debt Quadrant, but more on this later.

Advantages of No-Code Solutions

The appeal of both Low-Code and No-Code is pretty obvious. By removing code organizations can remove those that write it — developers — because they are expensive, in short supply, and fundamentally don’t produce things quickly.
The benefits of these two forms of applications in their best forms can be pretty substantial:
  • Resources: Human Capital is becoming increasingly scarce — and therefore expensive. This can stop a lot of ambitious projects dead in their tracks. Low-Code and No-Code tools minimize the amount of specialized technical skills needed to get an application of the ground, which means things can get done more quickly and at a lower cost.
  • Low Risk/High ROISecurity processes, data integrations, and cross-platform support are all built into Low-Code and No-Code tools, meaning less risk and more time to focus on your business goals.
  • Moving to Production: Similarly, for both types of tools a single click is all it takes to send or deploy a model or application you built to production.
Looking at these advantages, it is no wonder that both Low-Code and No-Code have been taking industries by storm recently. While being distinctly different in terms of users, they serve the same goal — that is to say, faster, safer and cheaper deployment. Given these similarities, both terms will be grouped together under the ‘No-Code’ term for the rest of this article unless otherwise specified.

List of No-Code Data Tools

So far, we have covered the applications of No-Code in a very general way, but for the rest of this article, I would like to focus on data modeling. No-Code tools are prevalent in software development, but have also, in particular, started to take hold in this space, and some applications even claim to be an alternative to SQL and other querying languages (crazy, right?!). My reasons for focusing on this are two-fold: 
Firstly, there is a lot of existing analysis around this problem for software development and very little for data modeling. Secondly, this is also the area in which I have the most expertise.
Now let’s take a look at some of the vendors that provide No-Code solutions in this space. These in no way constitute a complete list and are, for the most part, not exclusively built for data modeling. 

1. No-Code Data Modeling in Power BI

Power BI was created by Microsoft and aims to provide interactive visualizations and business intelligence capabilities to all types of business users. Their simple interface is meant to allow end-users to create their own reports and dashboards through a number of features, including data mapping, transformation, and visualization through dashboards. Power BI does support some R coding capabilities for visualization, but when it comes to data modeling, it is a true No-Code tool.

2. Alteryx as a Low-Code Alternative

Alteryx is meant to make advanced analytics accessible to any data worker. To achieve this, it offers several data analytics solutions. Alteryx specializes in self-service analytics with an intuitive UI. Their offerings can be used as Extract, Transform, Load (ETL) Tools within their own framework. Alteryx allows data workers to organize their data pipelines through their custom features and SQL code blocks. As such, they are easily identified as a Low-Code solution.

3. Is Tableau a No-Code Data Modeling Solution?

Tableau is a visual analytics platform and a direct competitor to Power BI. They were recently acquired by Salesforce which is now hoping to ‘transform the way we use data to solve problems—empowering people and organizations to make the most of their data.’ It is also a pretty obvious No-Code platform that is supposed to appeal to all types of end-users. As of now, it offers fewer tools for data modeling than Power BI, but that is likely to change in the future.

4. Looker is a No-Code Alternative to SQL

Looker is a business intelligence software and big data analytics platform that promises to help you explore, analyze, and share real-time business analytics easily. Very much in line with Tableau and Power BI, it aims to make non-technical end-users proficient in a variety of data tasks such as transformation, modeling, and visualization.

You might be wondering why I am including so many BI/Visualization platforms when talking about potential alternatives to SQL. After all, these tools are only set up to address an organization’s reporting needs, which constitute only one of the use cases for data queries and SQL. This is certainly a valid point, so allow me to clarify my reasoning a bit more.

While it is true that reporting is only one of many potential uses for SQL, it is nevertheless an extremely important one. There is a good reason why there are so many No-Code BI tools in the market—to address heightening demand from enterprises around the world — and therefore, it is worth taking a closer look at their almost inevitable shortcomings.

In this post, you will learn how to execute penetration tests with OWASP Zed Attack Proxy (ZAP). ZAP is a free web app scanner which can be used for security testing purposes.

1. Introduction

When you are developing an application, security must be addressed. It cannot be ignored anymore nowadays. Security must be taken into account starting from initial development and not thinking about it when you want to deploy to production for the first time. Often you will notice that adding security to your application at a later stage in development, will take a lot of time. It is better to take security into account from the beginning, this will save you from some painful headaches. You probably have some security experts inside of your company, so let them participate from the start when a new application needs to be developed. Nevertheless, you will also need to verify whether your developed application is secure. Penetration tests can help you with that. OWASP Zed Attack Proxy (ZAP) is a tool which can help you execute penetration tests for your application. In this post, you will learn how to setup ZAP and execute tests with the desktop client of ZAP. You will also need a preferably vulnerable application. For this purposes, Webgoat of OWASP will be used. In case you do not know what Webgoat is, you can read a previous post first. It might be a little bit outdated because Webgoat has been improved since then, but it will give you a good impression of what Webgoat is. It is advised to disconnect from the internet when using Webgoat because it may expose your machine to attacks.

Proxima Vara, a variable font version of the enormously popular Proxima Nova type family, has just been released.

Designers love Proxima Nova for the simplicity of its letterforms, its wonderful rhythm, and its generous x-height that all combine to produce a highly legible, modern typeface — that also happens to be cheaper to deploy than many similar designs.

The variable version allows designers to tweak the weight from 100–900, the width from a condensed 50% to a wide 100%, and the slant from 0–12.5 degrees. In total, there are 5,000,000 styles available.

Because it’s a variable font, Proxima Vara delivers all of those styles in a single file that is only moderately larger than a single Proxima Nova style.

Proxima Nova has been a go-to font for designers for over a decade. Commonality had stripped away some of its shine, but the addition of a new variable edition promises to re-popularise its use.

Try out Proxima Vara on its microsite; it’s available to download from $99.

Typography is one of the most important elements of any site, having a measurably large impact on brand and experience.

So fundamental is it that making wholesale changes to your typography — opting for a new font, changing the measure, increasing leading — is complex and fraught with potential time-sinks.

But there are some simple changes that you can make to your typography that won’t break your grid and can be achieved in 30 minutes or less. Here are eight of the easiest.

1. Increase Color Contrast

When laying out text, it’s common for designers to see text as a block within a visual design. A designer’s relationship to text is very different from a user’s; a designer positions text as a shape, a user reads it line by line. Consequently, designers tend to underestimate the amount of contrast text requires.

Light grey text is aesthetically beautiful but functionally useless. Text is meant to be read and needs to meet WCAG AA standards on desktop and WCAG AAA standards on mobile — or in any situation with many ambient light sources. The larger the text is, the more leeway you have.

Text should be thoroughly tested for contrast, but as a starting point, 18px text on a white background should never be lighter than #595959.

2. Tighten Heading Spacing

The vast majority of typefaces are designed for use as body text — large blocks of running text, multiple lines long. When the font was made, it was spaced for this use.

Unlike running text, headings tend to be short and are surrounded by more whitespace — especially above and below. Extra whitespace visually floods the negative space in the word shapes and forces letters apart.

To compensate, tighten the letter-spacing and word-spacing of headings by 1–5%.

3. Loosen Non-Word Spacing

When we read, our brain doesn’t spell out words letter by letter; it recognizes word shapes and even word groups’ shapes.

Most micro-typography is concerned with not disrupting those word shapes. However, there are times when you do want to prevent words from forming and allow individual characters.

Loosen the letter-spacing on any text intended to be read as a series of characters, such as serial numbers, tracking codes, and tabular data.

4. Use System Fonts for Inputs

Privacy is a big issue for users. Anything you can do as a designer to reassure users their data is safe will increase your site’s positive UX.

Style your HTML inputs to use system fonts — the default fonts set by the OS your user is accessing the site with. This creates a clear delineation between the brand data in the brand fonts and the user’s data in the user’s fonts.

Using system fonts in this way encourages the user to feel ownership of their data, builds trust, and increases conversions.

5. Mark Paragraphs Once

Paragraphs of text need a visual indication that they have begun. There are three ways in which this is normally conveyed: following a heading, with a vertical space before the paragraph, or indenting the first line.

Each paragraph should use one of these indicators and one only. Due to the nature of web content and the benefits headings have for quickly scan-reading content, for most sites, the best choice is a combination of following a heading and vertical spacing.

6. Use Genuine Styles

For various reasons ranging from the availability of fonts to aggressive optimization, it’s common for sites to fake alternative styles using CSS. Italics can be faked as obliques with a skew, bold weights can be faked by using the browser’s defaults, and small caps can be faked by setting text to uppercase and reducing the font-size.

These tricks do more harm than good, creating distorted word shapes that interrupt the natural flow of text.

If you cannot deploy genuine italic, bold, and small caps, then don’t fake them. Find alternative ways of creating emphasis, such as changing colors.

7. Use the Correct Quotes

Apostrophes, single, and double-quotes are specific characters. Most fonts provide a glyph for them that is distinct from the quick single or double-quote key on your keyboard.

These quote marks are most commonly referred to as “smart” quotes because word-processing apps usually have the option to be “smart” about which glyphs they use.

Using the correct quotes is one of the simplest ways to deliver a refined piece of text.

8. Hyphenate Text Properly

Hyphenation is the breaking of a word over two lines. It allows a less extreme ragged-right text, and it is vital on mobile devices where the available page width is relatively small compared with desktop.

The web has surprisingly poor support for correct hyphenation, but it is gradually improving, and it can be applied as a progressive enhancement.

CSS allows you to set hyphenation to none (no hyphens), auto (the browser inserts automatically), and manual (in which you specify where hyphens should appear using the soft hyphen character).

Typographically, a hyphen may be inserted in any word that is five characters or longer; there must be at least two characters preceding the hyphen and at least three following the hyphen.

You should never hyphenate three consecutive lines of text, but addressing this requires JavaScript. You can minimize this problem by increasing your measure.

As a consistent user and developer on the OpenShift platform over the years, I’ve tried helping users by sharing my application development content as we’ve journeyed from cartridges all the way to container base development.

With container based development we’ve also transitioned from using templates to define how to deploy our tooling and applications, to operators. There are many examples of how to work with the templated versions of our applications around decision management and process automation found on Red Hat Demo Central and JBoss Demo Central.
