If you just got started with Zig , you might quickly want to use a hashmap. Zig provides good defaults, with a lot of customization options. Here I will try to guide you into choosing the right hashmap type. 60-second explainer You probably want: var my_hash_map = std . StringHashMap ( V ). init ( allocator ); Or if you do not have string keys, you can use an Auto hashmap instead: var my_hash_m....

Rails 7 introduced import maps as the new default way to manager javascript. To quote the readme from importmap-rails: Import maps let you import JavaScript modules using logical names that map to versioned/digested files – directly from the browser. So you can build modern JavaScript applications using JavaScript libraries made for ES modules (ESM) without the need for transpiling or bundling . This frees you from needing Webpack, Ya....

A very touching Akhil Sharma in The New Yorker : Not long after we began dating, my now wife, Christine, and I started making up stories about the child we might have. We named the child—or, in the stories we told about him, he named himself—Suzuki Noguchi. Among the things we liked about him was that he was cheerfully indifferent to us. He did not wish to be either Irish (like Christine) or Indian (like me). Suzuki was eight, and....

I started this blog few weeks ago and I installed, despite my will, Google Analytics but, just few days after… G. Analytics has been declared illegal in EU. Then? Okay, first a bit of background: everyone is curious of how many visitors, from where and from which referral site, is coming to his website. And I’m too, so what is the easy to install, free and detailed analytic service? Google Analytics, you bet. Well, maybe it’s true, if you....

I wanted to use Blackblaze's B2 service to host uploads for this site using Active Storage. I wrote this up when I couldn't find a guide to configure the two to work together. B2 advertises itself as the most affordable cloud bucket storage. 🤞 here's to hoping it remains competitively priced. Rails 5.2 introduced Active Storage, a simple way to add attachments in your Rails applications. Rails 6 introduce Action Text with simple built-....

ArgoCD Health Checks: How to create custom Health Checks to validate resource statuses

Or how health checks avoid me from running into issues with controller-managed resources Here's an interesting problem I ran into while doing some work a few days ago. I was working on a pipeline to deploy new resources using ArgoCD. Everything was going great until one of the Kubernetes resources was, in fact, a resource managed by a Kubernetes controller: that is, applying it will not create it, it will merely tell the controller to cre..

I see a lot of dislike towards new year resolutions. There is a assumption that new year resolutions is bad and ineffective. Atleast some people think new year resolutions as a finalised plan. It is not. It is just a rough script for how you want your new year to go. You need to be working on it everyday. Trim it down or expand as necessary. You don’t have to hit it all. In fact, most people won’t hit it all. And that is fine. It is definit....

"wait-for", a tiny utility to wait for TCP or UDP resources to be ready

Use it in your Kubernetes clusters to wait for resources to be ready, like SQL Databases I know I'm not the first one to create this and, in fact, there are a plethora of options out there to use as of right now. Still, I wrote my own version of wait-for, and there are a few differences that make it to be a little more useful than the alternatives. For those of you who have never heard about this, wait-for is a very simple and tiny applic..

Tomorrow we’re releasing a major project on which we’ve been working non-stop for two and a half years. No matter how many years in the trenches, release day always makes me a bit nervous. Experience does help. I know there will be problems, and we will solve them. Some customers will complain, and those will be the most vocal. The vast majority of them will appreciate the effort, enjoy the features, and stay silent. That’s how it works. We..
