Thoughts on technology, movies, and everything else
Category: Web work
These days, most of my work is very related to the online world. Building web sites, reviewing web applications, integrating with web services, coordinating people who are far away from each other, etc. Whenever I find a new tool or service or an innovative, interesting idea about working online, I share it in this category.
This is probably way too far out for most people using MySQL for their web applications. But it does highlight the technical complexity of running high load web applications, and how some of the issues can be solved or worked around.
While I understand it a lot better now, I still much prefer the merge approach. It’s simpler and less dangerous, and maintains the full history. This might get noisy at times, but works as a last resort when trying to understand what was going through the developer’s head when he was working on a piece of code.
WordPress 5.0 has been released today. It is by far the largest update to the system since … since I can remember. In fact, to some, it might look like a completely different system, thanks to a totally new editing experience – Gutenberg.
I have already upgraded this blog to the new version, and I’m writing this post with the new editor. It is awesome! It’ll take some getting used, but not because it’s difficult, rather because I’ve been using WordPress for too long.
I also can’t wait to see what all the creative people will come up with in their themes and plugins, pushing WordPress websites to the new high.
Many software projects deal with the lists of countries and currencies. Some of the most common tasks include country an currency dropdowns, country flags next to the IP, or pre-filling country codes in phone numbers.
All of that information is of course standardized and you often just need a library or two to provide and use it. And there are many of those. We’ve been mainly using these two:
Today, however, I came across a better option – antonioribeiro/countries, which is a collection of country and currency information for Laravel PHP framework. Laravel is not required though. This library provides way more information and in a much more flexible way. It includes:
266 countries (with more codes, common names, official names, and more)
“Practical Cryptography for Developers” is a free book (with GitHub repository) by Svetlin Nakov, which aims at teaching developers some of the most practical concepts of cryptography. The book covers hashing functions, random generators, symmetric and asymmetric keys, digital signatures, and more. Each chapter is rich with diagrams, illustrations, code samples, as well as exercises.
Now that PHP 7+ sorted out a whole bunch of problems with type-hinting of parameters, return values, variables and properties, we turn our attention to somewhat deeper issues.
Array is a native citizen in PHP. Arrays are very convenient and are widely used. However, if you stop and think about the times where you had to figure out somebody else’s code, I’m pretty sure complex arrays will come to mind at some point.
I’ve recently came across two completely independent blog posts which talk exactly about this particular area of problems:
Both are explaining the issues very well and make valid points. As far as solutions and better ways go, apart from the approaches mentioned in these blog posts, I also remembered a recent blog post from which I linked to the data transfer object library, that solves exactly that.
RoadRunner is a high-performance PHP application server, load-balancer and process manager, written in Goland. It sounds like an excellent replacement for the built-in PHP server, and even more than that – it’s production-ready. And it works on Windows too.
RoadRunner is an open source (MIT licensed) high-performance PHP application server, load balancer and process manager. It supports running as a service with the ability to extend its functionality on a per-project basis.
RoadRunner includes PSR-7/PSR-17 compatible HTTP and HTTP/2 server and can be used to replace classic Nginx+FPM setup with much greater performance and flexibility.
