How to become an author

This is a post about first steps and first pitfalls in modernization of old enterprise application using "supersonic subatomic java" quarkus as it is positioned by RedHat.

Initial setup

In the end of 2019 I was invited to work in a project in our company, where an old monolithic application should be split into micro-services. Basic reasoning behind this decision was, that framework which is used in application is near to it's end-of-life. The application should be rewritten in any case. If it should be rewritten in any case, why not to split it into micro-services?

Since last 10 years, I was working mostly with java and we had in the project specialists with java knowledge, we have decided to give java-based frameworks a try for back-end functionality.
OK, let's use spring-cloud for that purpose, was our first thought. But then, we have had a look onto quarkus, which has been released in the end of 2019. We have decided to give it a try, keeping in mind building of native applications using GraalVM.

Native applications from our perspective could give us following benefits:

• shorten start time of container
• reduce resource consumption of container and application

We were aware about possible drawbacks of this solution:

• no experience in our team with quarkus framework
• significantly less amount of available feedback from community, since this is very young framework

The case: You fire up a professionally prepared Linux image at a cloud platform provider (Amazon, DO, Google, Azure, etc.) and it will run a kind of production level service moderately exposed to hacking attacks (non-targeted, non-advanced threats).

What would be the standard quick security related tuning to configure before you install the meat?

release: 2005, Ubuntu + CentOS (supposed to work with Amazon Linux, Fedora, Debian, RHEL as well)

In just a few years, quantum computing and quantum information theory has gone from a fringe subject offered in small classes at odd hours in the corner of the physics building annex to a full complement of classes in well-funded programs being held at quantum centers and institutes at leading universities.

The question now for many would-be quantum computer students is not, “Are there universities that even offer classes in quantum computing,” but, rather, “Which universities are leaders at quantum computing research.”

We’ll look at some of the best right now:

The Institute for Quantum Computing — University of Waterloo

Problem

Authorization is one of the first problems developers face upon starting a new project. And one of the most common types of authorization (from my experience) is the token-based authorization (usually using JWT).

From my perspective, this article looks like "what I wanted to read two weeks ago". My goal was to write minimalistic and reusable code with a clean and straightforward interface. I had the next requirements for my implementation of the auth management:

• Tokens should be stored in local storage
• Tokens should be restored on page reload
• Access token should be passed in the network requests
• After expiration access token should be updated by refresh token if the last one is presented
• React components should have access to the auth information to render appropriate UI
• The solution should be made with pure React (without Redux, thunk, etc..)

6 Steps for Successfully Wrapping up a Software Development Project

1. Document future needs

Background or why all of this is necessary

PHP evolves continuously and they just released their latest PHP 7.4 update. Performance and speed keep advancing, as we have already been proved in the past PHP 7 releases. Preloading is one of the most thrilling new updates. It quickens script execution and makes code cleaner and faster due to the simplified common lines of code.

PHP is an important element in the world wide web and is used in over 79% of all websites. Well-known websites like Facebook, Wikipedia, WordPress and much more are using PHP.
We can see a double speed increase when looking at WordPress sites running PHP and comparing PHP 5 and 7. While using the latest PHP version out there — WordPress powered websites gain the most.
