Renato Athaydes. Comparing JVM alternatives to JavaScript Written on 17 Apr 2019, 09:11 PM (Last updated on 21 Apr 2019, 07:56 PM) I am mostly a backend developer, but every now and then I need to do some frontend work.

Even if just for personal use. For that reason, I’ve been following developments in the JavaScript world from a distance, but I dislike much of what I see. The thing I dislike most is how complex the toolchain for a professional JavaScript application has become. The MDN page on JavaScript actually shows how to use HTML and JS as it was intended - no build tools, no frameworks.

The JavaScript toolchain of today has all the complexity of backend toolchains, and then some. This Pluralsight JS development environment course suggests you need 32 tools to build your application (e.g. babel, chai, cheerio, eslint, mocha, webpack…). Reuse for better Software delivery – Pareture. Thoughts on software reuse TLDR: When undertaking a new project it is a good rule to err on the side of reusing things.

Reuse for better Software delivery – Pareture

I think that we (IT professionals) should always seek to centralise the good things we do, at least to the extent that we can influence. By this, I mean to largely reduce the variability in the way something is being done in an organisation. We understand common use at many levels. Franchise restaurants across the globe have largely the same menu, decor and kitchens for a consistent experience. Don’t repeat yourself (DRY); an architecture principle which is simple, useful and quite popular. The Difference Between SQL’s JOIN .. ON Clause and the Where Clause. A question that is frequently occurring among my SQL training‘s participants is: What’s the difference between putting a predicate in the JOIN ..

The Difference Between SQL’s JOIN .. ON Clause and the Where Clause

ON clause and the WHERE clause? I can definitely see how that’s confusing some people, as there seems to be no difference at first sight, when running queries like these, e.g. in Oracle.

Building Resilient Applications: Introduction – Patrus Transportes

If we look for the definition in the dictionary (Google) we will see: In physics: the ability of a substance or object to spring back into shape; elasticity. Figuratively: the capacity to recover quickly from difficulties; toughness. Programming: doing it more vs doing it better – Kevin Martin Jose. A few years ago, very early into my programming career, I came across a story: The ceramics teacher announced on opening day that he was dividing the class into two groups.

It's a simple way to deploy with confidence. In this article I'll explain what a Smoke Test is and why you should implement one to catch bugs early in your website, API, or application. 9 tips for moving code to microservices. Many shops are looking to break big existing monolithic applications into containerized microservices running on distributed architectures.

9 tips for moving code to microservices

Docker and Kubernetes are the most popular technologies that can make this happen, but others are sprouting up as containerization grows more popular, and you might soon find yourself looking to make this move. There are many good reasons to do so as part of an ongoing digital transformation project. "The benefits are numerous—from increased team productivity to easier automated testing, rapid and flexible deployment models, and higher overall resiliency," says Ev Kontevoy, CEO and co-founder of Gravitational, creator of the open source Gravity project, which converts complex cloud applications into single-file Kubernetes appliances. But there are potential pitfalls too, Kontevoy says, including "the need for careful planning and higher R&D investment upfront. " Crafting a Command Line Experience that Developers Love. If you're setting out to build a highly usable developer tool, it goes without saying that a proper CLI to interface with your API is paramount.

Crafting a Command Line Experience that Developers Love

As Zeit and Heroku have been setting the tone for these types of developer tools by doing extensive research into best practices when it comes to a command line “experience”, we started our quest by digging in to their findings. Since the Stream CLI is currently in public beta, the methods and philosophies we found from our research, as well as those we unearthed ourselves are fresh in our minds and we wanted to take a few minutes to outline what we found to be best practices among other CLI tools and developers’ needs when it comes to building a proper CLI.

Contrairement aux rumeurs, Microsoft n'a pas l'intention d'abandonner complètement le navigateur par défaut de Windows 10. Dans un billet de blog, Joe Belfiore, vice-président de Windows Corporate, a expliqué que Microsoft va remplacer son moteur de rendu EdgeHTML et son moteur JavaScript Chackra par Blink et V8 de Chromium. Ce sera donc un changement technologique sous le capot et l'interface de Microsoft Edge sera conservée. Arbre de décision pour trouver la méthodologie d'étude utilisateurs adaptée au besoin.

A JavaScript-Free Frontend. Slimvoice - A Webapp Without JavaScript is a series where I document how I rebuilt my app, Slimvoice, using as little JavaScript as possible. I've tagged this series with JavaScript to present JavaScript alternatives and encourage those who reach for a SPA for every project to give it a second thought.

I built the first version of Slimvoice on Angular 1 with a Node.js backend and MongoDB in 2014 (those were all the rage back then). In 2015 I decided to completely revamp the UI and redesigned and rebuilt it in React. In hindsight, all of that was crap. With the new version I wanted to prove that it was possible to deliver an amazing user experience with a great design while drastically reducing the complexity of the code, maximizing reliability, and minimizing the cost to the end user.

Why use Go over other languages? As a software engineer, the technology landscape is constantly changing. Programming languages come and go, older languages receive new libraries and frameworks to bring them up to modern standards & methodologies.

Will the new languages pass the test of time, or just be remembered as the next hipster fad. With so much flux and change, it can be a difficult decision to select technologies to build your product and platform with. Speed up PHP Using OPcache and Memcached. The Twelve Factor App — A Very Brief Summary – Toni-Leigh Sharpe. Break functional and orchestration responsibilities for better testability. Elastic, Cost Efficient CI/CD with Jenkins and Milpa. If you work as a developer, there is a good chance you know and use Jenkins, the leading open source automation server for CI/CD. The classic Jenkins setup involves a master and usually several agents: the master is responsible for coordination and provides the user interface (via a web UI and API), and the agents are designed to run the CI/CD jobs the user configured.

The master and the agents in most cases run in separate virtual machines or containers. This distributed setup is great for scalability: as your team and the number of builds and jobs they want to run grow, it is easy to add another agent node that can perform more work. The ability to scale to meet workload demands makes public cloud a great fit for Jenkins environments where capacity requirements vary over the course of the day or week. The Difference Between Public and Private in Java. Gmail devient le premier fournisseur principal de messagerie à prendre en charge les rapports MTA-STS et TLS, pour améliorer sa sécurité. Actuellement, quand deux relais de messagerie doivent échanger des mails, la sécurité du transport des messages est généralement assurée par un chiffrement des échanges en TLS. Cependant avec TLS, le serveur expéditeur ne peut pas indiquer sa politique de chiffrement et le serveur destinataire ne peut pas la vérifier.
