We are releasing our HTML to PDF REST API to public preview: https://html2pdf.appbeat.io/ We are using this tool internally for generation of various PDF documents. It uses Chrome engine for HTML rendering and creates really nice looking documents. It supports synchronous and asynchronous operation where you can be notified about PDF conversion result via webhook.

When an outage hits your service, everybody starts talking. Your engineers are talking about what caused the problem, and how to fix it; your management is asking about when it’ll be fixed; and your customers are telling the world that they’re not happy. But there’s an even more important conversation you should be having: communicating with your users about the issue.

Performance is one of the most important concerns when developing an application. All software developers should monitor and improve performance in every layer of the application. From the database to the server-side language, there are plenty of opportunities for performance issues to arise, and the front end is certainly no exception. So that’s why today we’re talking about JavaScript performance and how to improve it.

Unresponsive and slow pages are both terrible for any website. Even with the best user interface (UI), unresponsive and slow pages negatively affect the customer experience and the brand's reputation. Research from the Nielsen Norman Group has determined that the average user will leave a site after about 10 seconds of waiting for a page to load. If your page takes longer than a few seconds to load, it's time you check your IIS server logs.

Today, we’re bringing you an update of the performance/exceptions sample page. This update includes a number of improvements that will help you navigate and filter the available samples faster and more smoothly. We’re bringing these changes as an iteration of sample navigation improvements that we launched a while ago. We received valuable feedback from our users: the overlay made the navigation choppy instead of fluent.

Grafana dashboards can do a lot, but do you know how much more you can get out of them by configuring them as code? That was the topic of a recent FOSDEM 2020 talk by Grafana software developer Malcolm Holmes and Julien Pivotto, an open source consultant at Inuits. In their presentation, the pair discussed Grafonnet (a Jsonnet library to generate Grafana dashboards), provided tips and tricks about how to use it efficiently, and explained how to fully manage your Grafana instances from code.

This article is a continuation of Part I (A comprehensive guide to migrating from Python 2(Legacy Python) to Python 3), which details the changes, and improvements in Python 3, and why they are essential. The rest of the article describes automated tools, strategies, and the role of testing in the migration from Python 2 to 3.

There are dozens of great languages to learn. Today we’ll be breaking down the differences between two of the best: PHP vs Python. Which one is best for your application? Which is going to give you the best return on your development time? We’ll pit these two head-to-head and find out which is the best choice for you.

My computer programming teacher had always told me that 10% of our time is spent developing 90% of our application, and the other 90% of our time finishing the last 10% of our project. Even with a good project plan and a concept that makes logical sense, most of our time will be consumed with fixing errors. Moreover, with JavaScript, our application can run without obvious errors preventing it from being run, so we have to employ several techniques to make sure everything is running smoothly.
