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.
BellSoft issued a new version of Liberica Native Image Kit (NIK), 22.0.0.2, so in this short article, I will provide a tutorial on how to use it with the Quarkus framework.
Liberica NIK is based on the open-source project GraalVM (Community Edition) and is compatible with many platforms, including lightweight musl-based Alpine Linux. Liberica NIK in essence is a utility that converts JVM-based applications into native executables (AOT compilation).
Jamstack (JAMstack), is one of the most popular (and rapidly growing) tools for app and website creation. A unique ecosystem of functionality, Jamstack promises developers the support they need to create powerful websites and progressive applications.
For a while, Jamstack was mostly written off as just another buzzword in the developer space. However, today, it’s growing to become a powerful investment for many business leaders. Even big companies are getting involved, like Cloudflare, with Cloudflare pages, and Microsoft with Azure Static Web Apps. Elsewhere, we’ve seen brands like Shopify, PayPal, and Nike getting involved too.
So, what exactly is Jamstack, and is it time you transitioned over? Let’s find out…
Jamstack, otherwise known as “JAMstack,” is the name of a developer ecosystem made up of JavaScript, APIs, and Markup (hence: JAM). The solution is a web development architecture allowing developers to access static website benefits, such as higher security and better performance, while still unlocking dynamic database-oriented CMS.
The Jamstack solution allows companies and developers to build a dynamic website where real assets are pre-rendered static files in a CDN. The dynamic environment runs on JavaScript client-side, through serverless functions.
For a better insight, let’s compare Jamstack to the LAMP stack development strategy, which originated from the four open-source components many developers used to build sites: Linux, Apache HTTP, MySQL, and PHP.
With LAMP, each user request for a page forces the server to query a database — unless the page is cached — and combine the result with page markup data and plugins. Jamstack websites serve pre-built optimized assets and markup solutions quickly because the files are already compiled on a CDN. There’s no need to query the database.
Jamstack workflows dramatically reduce cumbersome issues with development and excess maintenance, making them highly appealing to developers.
Jamstack won’t be the ideal development tool for everyone, but it has a lot of benefits to offer. By fetching HTML from a CDN, the system doesn’t have to wait for HTML to be combined and returned to clients. The solution also provides an improved developer experience with static methods.
Using Jamstack, developers can build fantastic static files ready to serve by request, hosted on a global CDN. Some of the biggest benefits of Jamstack include:
In a lot of ways, Jamstack is an innovative and revolutionary solution for development. It can help you to create a far more engaging website and present your company in an incredible way. Of course, that doesn’t mean there are no limitations to be aware of.
Jamstack is developer-friendly, for instance, but it’s not beginner-friendly. You will need at least some knowledge of web development to start unlocking the benefits. You’ll need to understand things like Vue or React, but you should develop a tool anyone can use with a bit of work.
There’s also a handful of things you can’t pre-generate, like user-specific and real-time data. So, this means you may not be able to use Jamstack effectively on projects requiring these kinds of data. Building an analytics dashboard, for instance, probably isn’t a good idea with Jamstack. Other issues for some developers may include:
Now you know the basics of Jamstack, let’s look at some of the tools you can use to design an incredible website or application within the Jamstack environment.
There are tons of tools within the Git ecosystem common among Jamstack developers. Starting with Git itself. Git represents a powerful free, and open-sourced distributed version control system. With this solution, companies can handle everything from small to enterprise-level projects with efficiency and speed. The solution is extremely easy to use and learn, and outclasses a range of tools like Perforce, ClearCase and Subversion.
GitHub Pages and GitLab pages are two hosting services for Git repositories with built-in services to host static pages from out of your codebase. This makes the two solutions fantastic for when you’re building a Jamstack website. You can access the functionality for free too.
GitLab gives you a comprehensive DevOps platform to work with, where you can enjoy a comprehensive CI/CD toolchain out of the box. The comprehensive solution, delivered as a single application, changes the way security, development, and Ops teams integrate and collaborate. Gitlab helps to accelerate software delivery on a massive scale.
AWS Amplify, created by Amazon Web Services, is a development platform packed full of useful features for people in the Jamstack environment. The Amplify offering aims to reduce the complexities associated with Amazon Web Services for mobile and web deployment. You get 12 months of hosting for free with new accounts, and you get Storage with Amplify too.
The Amazon Amplify solution dramatically improves the regular AWS workflow, especially if you’re just a novice user. There’s a huge documentation hub to help you too, which is way more convenient than Amazon’s usual documentation solutions. Amplify is still accessed from a somewhat bloated console, however.
With AWS Amplify, companies can access features like a comprehensive data store to sync data between the cloud and websites. There’s also easy-to-use interface access across all different categories of cloud operations. The service works well with a range of JavaScript central tools.
Netlify is a pioneering solution in the Jamstack environment, allowing users to go dynamic with their websites and applications on their own terms. You can access a range of add-ons and integration, access your favorite tools, and make your own. The flexible environment enables developers to run websites on a multi-cloud infrastructure designed for speed and scale automation.
Built to be entirely secure from the ground up, Netlify makes it easy to build a site that’s custom-made for performance and deployed directly. You don’t need to worry about managing, scaling and patching web services, which means you can more quickly implement your Jamstack architecture.
Unlike other large legacy apps, Jamstack projects are neatly separate from your front-end pages and UI from the backend databases and apps with Netlify. Using this service, the entire front-end can be pre-built with highly optimized static assets and pages, and developers can deliver new web projects faster than ever before.
Inspired by the functionality of PHP, Next.JS is a solution for pre-rendered JavaScript modules. The solution allows developers to easily export the components of their apps and perform individual tests to determine how each element works. You can also access a wide range of components and modules from NPM. The Next offering allows developers to save time, removing the need to use webpack bundles and transform with compilers.
The full solution is extremely intuitive, ensuring developers can create solutions quickly. What’s more, the technology you build will allow you to load only the bundle needed from your JavaScript workflow, rather than all the JavaScript at once. Pre-fetching, one of the features of Next.JS, also picks up where standard code-splitting leaves off, allowing for optimized bundles of code to load seamlessly.
Next.JS also supports hot-module replacement. This means instead of reloading an entire application when you change the code, you only recreate the modules you’ve altered.
Probably the most widely-recognized of all the JavaScript frameworks, Angular, designed by Google engineers, appeared first in 2012, offering developers a new way to create dynamic pages. Before this technology, there were other opportunities for creating dynamic pages, but they were nowhere near as convenient or speedy.
Angular is probably one of the most essential tools companies can use when building a Jamstack website or environment. The front-end web development tool attracts developers from all over the world. Every version is packed with features and constantly upgraded to ensure you can generate the best results.
Angular extends HTML file functionality with powerful directives, and it requires very little effort to enable these directives too. All you do is add the ng- prefix to your HTML attributes and you’re ready to go. Angular also allows developers to create widgets leveraging editable data with two-way binding. This means developers don’t have to write code that syncs constantly between the model and view.
With Angular, developers also get access to things like virtual scrolling, which can help with displaying large lists of elements performantly, rendering on the items that fit on the screen to reduce loading times.
Another must-have tool in the JavaScript world for Jamstack, the React solution was launched first in 2013, and has won thousands of customers across the globe thanks to fantastic functionality. Today, the full landscape is maintained by Facebook, along with all the members of the standard developer community. The solution is used by some of the biggest giants in the tech industry, like Netflix, PayPal, and Apple.
React is a true pioneer in the Jamstack ecosystem, with its sensational approach to simple and straightforward solutions for JavaScript management. You’ll be able to access batched and virtual DOM updates, which makes it easier to unlock components quickly, and write your components the way you see them. There’s also the added benefit that React is compatible with a lot of tools.
You can build a comprehensive app or website with the help of React, and you’ll have no trouble accessing some of the top features, particularly with plenty of support available from the React community.
Created from the ground up to improve user experience on a comprehensive level, Gatsby is a static site generator with heavy focus on things like SEO, performance, and accessibility. The solution offers plenty of out-of-the-box features to help developers deliver the most immersive solution for their users, without unnecessary complexity.
Gatsby users pre-configuration to develop static websites giving developers faster loading pages, stronger code splitting, and server-side rendering. You can also access features like data prefetching, asset optimization, and quick image loading. Gatsby boasts excellent documentation and starter packs to help you get your site up and running more quickly.
The GraphQL data layer of Gatsby also means the system can collect your data from anywhere, including your CMS, JSON, Markdown, and APIs. More than just your standard site generator, this is a tool built specifically with performance in mind.
Developing an effective Jamstack website means having access to the right CMS technology. Agility CMS wasn’t the first CMS solution to support Jamstack, but it is one of the better-known options. As one of the first headless CMS solutions to hit the market, the company has quickly captured the attention of a huge range of developers worldwide.
Agility CMS is a Jamstack pioneer, capable of helping developers to build a foundation for any online ecosystem. The technology is an API-first CMS with support for REST APIs, so developers can connect all the third-party apps and front-end frameworks they like.
The technology also gives developers the freedom to code their solutions their way. You don’t have to follow a specific set of guidelines for how content is created, but templates are available to fast-track development. Agility CMS also hosts and abstracts your database, so you don’t have to worry about connection strings, backups, and maintenance.
With a strong content architecture to help companies manage digital content and a partnership with Gatsby, Agility is ideal for Jamstack development strategies.
The Jamstack solution is more than just a buzzword in today’s development world. This unique approach to building incredible development experiences delivers an excellent advantage to both developers and their end-users. Fast, scalable, and full of solutions for customization, Jamstack is a powerful way to bring websites to life with simplicity and speed.
Every day, more companies take advantage of the Jamstack environment, and we’re constantly seeing a wide selection of new tools, APIs and offerings emerging to help enhance the Jamstack landscape too. This environment is definitely worth consideration for any developer looking to significantly speed up their development strategy.

The serverless journey started with functions – small snippets of code running on-demand and a short period in Figure 1. AWS Lambda in the “1.0” phase made this paradigm very popular, but it had its limitations around execution time, protocols, and poor local development experience.
Since then, developers realized that the same serverless traits and benefits could be applied to microservices and Linux containers. This leads us into what we’re calling the “1.5” phase in Figure 1. Some serverless containers here completely abstract Kubernetes, delivering the serverless experience through an abstraction layer that sits on top of it, like Knative.
A VPN is a way to keep your identity a secret and protect your traffic on the internet. Your internet traffic passes through a tunnel that encrypts your data that no one can see, such as your internet service provider or government when you connect to a VPN server.
Let us list down why you need to use a VPN.
Ubuntu Server has taken data centers around the world by storm. Whether you’re deploying Ubuntu for a large-scale project or for a small office, it is a stable, customizable, and powerful Linux distribution with innovative and cutting-edge features.
Ubuntu is a fantastic platform on which to build your servers — Jay LaCroix
‘Load Average‘ is an age-old metric reported in various operating systems. It’s often assumed as a metric to indicate the CPU demand only. However, that is not the case. ‘Load Average’ not only indicates CPU demand, but also the I/O demand (i.e., network read/write, file read/write, disk read/write). To prove this theory, we conducted this simple case study.
To validate this theory, we leveraged BuggyApp. BuggyApp is an open-source Java project that can simulate various performance problems. When you launch BuggyApp with the following arguments, it will cause high disk I/O operations on the host.
The concept of coroutine must be familiar to everyone now. After all, not only LUA, Go, and Kotlin but also C++ all support coroutines.
But different languages have different implementations. Such as LUA, coroutines will be scheduled when someone called yield() or resume().
If you were paying close attention to your IT department around the 8th of December, you might have heard some quiet sobbing and the occasional wail of, “Why? Why?! WHY?!” Now, it was the year 2020, so this might have seemed normal to you, but it’s actually something of a problem that could affect your business: CentOS is pretty much dead.
For the non-total-nerds among us, here’s the skinny: CentOS is a Linux-based operating system, typically used on servers. CentOS has been incredibly popular, and quite a few businesses run on it. But now, that’s changing.
CentOS is a Linux-based operating system, typically used on servers…But now, that’s changing
CentOS used to be released in thoroughly tested versions, the latest being CentOS 8. CentOS 8 was released in September of 2019 and was supposed to be supported for ten years. Now, it’s been decided that CentOS will no longer have versioned releases, opting for a rolling-release style of updates. That means there’ll be one version that constantly gets new software.
That’s cool in theory, but it means the operating system will be less stable overall. Essentially, it’s going to be used as a development branch of / testing ground for Red Hat Enterprise Linux and is no longer its own OS. If you have CentOS-based servers, you should migrate to another OS sooner rather than later.
And I just got my own CentOS-based VPS set up the way I wanted it.
Here’s the short, short version of the history of CentOS: Red Hat (an OS developer) has two Linux distributions of its own and has had for a long time. There’s the free and community-focused Fedora and the business-focused highly expensive Red Hat Enterprise Linux (AKA RHEL).
Funny story: RHEL, despite its expensive licenses, is still mostly made from open source code, which anyone can access and use. And it’s a good OS, particularly for people who like stability.
In 2004, some smart people took all the open-source parts of RHEL and made a brand new, nearly identical operating system with it: the Community Enterprise Operating System, or CentOS. Basically, people could download and use an enterprise-level server OS for free. All the documentation for RHEL was compatible, and you could get support from the community.
It was the perfect alternative for anyone who didn’t have the budget for expensive software licenses.
In 2014, Red Hat offered to partner with the CentOS community. The idea was basically this: “It’s pretty much the same software. If our company and your community work together, both our products will be better! We make our money from enterprise customers, anyway.”
Most importantly, with Red Hat doing a lot of the heavy lifting in terms of updates and support, the CentOS community could focus on growing in other ways.
Red Hat pinky swore [citation needed] that they were in this for the long haul, and CentOS did continue to flourish. You know, until 2020.
Red Hat must have eventually decided that having a popular free version of its own enterprise software and managing it themselves no less — wasn’t that good for business. So they all but shut the project down.
Well, technically, they just changed how it operated. Instead of producing tested, production-ready versions, CentOS is merely a testing ground for RHEL. It is no longer, in my opinion, a good option for anyone who wants to run a stable server.
So if you jumped on the CentOS 8 bandwagon, what should you put on your physical and virtual servers now? Well, you’ve got options.
For those who don’t mind going to a very different kind of Linux, Debian has been the picture of OS stability and sysadmin-friendliness for a long time. If you want more frequent software updates, the Debian-based Ubuntu Server is popular and pretty good.
Yes, that Oracle has a RHEL-compatible Linux distribution of its own. But it’s not a clone, exactly. I mean, this is Oracle. It’s set up to use their tools and ecosystem, so I hope you like Oracle products. But hey, the OS itself is free!
ClearOS is another RHEL-compatible OS that’s mostly doing its own thing, though I’m not entirely sure what that thing is. Does the company have some deal with Hewlett-Packard? Anyway, they do have a free community edition and paid editions for home and business use.
This is an upcoming release from the makers of CloudLinuxOS. It looks like they intend to load the new RHEL-based OS with some of their own tools, such as reboot-less server update tech. The first release is intended to be a more or less drop-in replacement for CentOS 8.
So the community that made and loved CentOS in the first place is, to say the least, ticked. They are so ticked that Greg Kurtzer (a co-founder of CentOS) has decided to do it all over again by making Rocky Linux and keep it in the community this time.
Again, the goal is to make a re-build of RHEL, a drop-in replacement for CentOS (at least for now). Eventually, the goal is to migrate from CentOS to Rocky Linux as easy as using a single, one-line command. The ETA for initial release isn’t quite set in stone, but I can personally vouch for how hard the community is working.
[See, full disclosure here… after writing this article, I joined the Rocky Linux documentation team.]
Some are out now, and others will be soon. Again, CentOS 8 will be supported until the end of 2021. CentOS 7, weirdly, will be supported until June 2024.
Migration shouldn’t be too complicated. Still, a pain in the rear that we have to do this at all, though.
