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.
You Don’t Need jQuery is a GitHub repository with a collection of code snippets that show how to do the most common jQuery bits in native JavaScript. The collection covers a whole range of subjects, like:
All examples should work just fine in all modern browsers.
Additionally, have a look at the You Might Not Need jQuery website.
Zabbix 4.2 has been released and it brings an impressive array of new features and improvements. Some of these are:
If you were waiting for a good reason to upgrade – this is it!
Alexey Nizhegolenko has an excellent 3-part series of articles that cover the setup of Kubernetes on the bare metal servers. Here are the parts:
If that’s not a hand-holding walk-through guide, then I don’t know what is.
“Programmer migration patterns” is an interesting attempt to identify where programmers start and how move from one programming language to another. This is not precise science, obviously. But I have to say that I mostly agree with the findings.
The first language that I learned (back in school) was BASIC, which then gave me some legs with Visual Basic later in college. Also in college, I’ve learned assembler, C, and Pascal, which guided me to some amateur and professional development with Delphi.
Soon after that I discovered Linux, which meant shell scripting. I played with awk, but I didn’t have to dive deep, as Perl was already available. Perl was probably my first true programming language, which I learned outside of school and college, and which I have been using for years to build all kinds of things. I still love Perl dearly, but the last few years I have been mostly using PHP, with some occasional Python.
JavaScript, however, is where I draw the line. I’ve been scarred by JavaScript back in the 90s, so I can’t force myself to go back. And then again, I don’t really have to. I’ll leave JavaScript, TypeScript, and node.js for the younger generations.
Let the source be with you!
One thing that I like about the modern world is that large technology companies are a lot more open than they were in the previous century. Many of them contribute to the Open Source ecosystem and frequently share their wisdom on how to use and not to use a particular technology.
Have a look at the recent post from Bitbucket blog: Searching DynamoDB: An indexer sidecar for Elasticsearch, for example.
It’s not your usual marketing nonsense about introducing a new needless service or self-praising review of a product. It’s a rather deep dive into a technical topic that has been getting a lot of attention for the last few years – NoSQL databases. Not only the blog post itself is interesting, but it provides plenty of useful links to other resources. Like this one, which covers database partitioning in depth. Or this one, which lists some of the best practices for designing and using partition keys effectively.
I wish more companies shared their technical insights like this.
