Optimizing Hugo Sitemaps to prioritize posts crawling over taxonomies

You might notice that I’ve been struggling recently with SEO and that I’ve been trying some tricks to improve it, but it feels not enough. I’ve been thinking about Google’s Crawl Budget1 and the way I could influence it to focus more on new and important content. Adding lastmod should help, but together with each new post added, Hugo generates a ton of taxonomy pages (tags, categories, etc) which also would have lastmod updated....

Nostalgy for old RPG games

I’ve been cleaning up old backups and found few screenshots from Ice Wind Dale, Baldur’s Gate 2 and Throne of Bhaal expansion. I’ve spend many good hours playing those games. I’ve read a dozen books from the Forgotten Realms realm . I remember being in a library (in the game) and spending there quite a lot of time, just to read few books. Playing those games was like a deep dive into the fantasy world, side by side to the characters from the books, or sometime against them....

Create a Virtual Bookshelf with Hugo and PaperMod

TL;DR If you don’t care about my reasoning, just jump to the description of installation and usage . Click here for a demo . I try to read at least one book each month. It’s not much, but that’s what I can afford. I read a lot of technical books, building my technical skill set, but a lot of random topics from business, psychology or fantasy. It happen to me many times that when I’ve been asked about specific book, I couldn’t remember “Where did I read it?...

Installing Oracle Instant Client on Ubuntu 24.04

New system, old problems. Getting Oracle Instant Client to work was a trouble 10 years ago and it’s not different today 🤣 There are two ways to install it on Ubuntu/Debian. First is “recommended”, but boring. Second is “crazy”, but have some benefits. As I’m doing it mostly in Docker images, that’s how I will present it. First, check for up to date versions  external link and links on Oracle’s official site....

Automatically setting 'lastmod' in Hugo pages with Git modification date

Following my recent SEO issues , I’m actively exploring ways to bolster my website’s ranking. One aspect I’m keen to address is expediting Search Engine indexing for pages that have been altered or updated. This is precisely the purpose of Sitemaps, a feature fully supported by Hugo1. However, there’s a limitation in how Hugo handles this by default. It sets the lastmod parameter to either the page’s creation time or the last build time....

How old are Official Docker images? 2024 Edition

Around 3 years ago I’ve checked the age of various base images available on Docker Hub. Curiosity recently got the better of me, prompting another investigation into the current state of affairs. Since then, there have been significant changes: CentOS 8 has reached its end of life  external link , prompting a shift to CentOS 8 Stream  external link , which is also nearing its demise 🤣 OpenJDK images have been deprecated  external link and no longer receiving updates....

Zed Code Editor as an Atom reincarnation

I was a big fan of the Atom1 code editor, so when it was discontinued and replaced by M$’s VS Code2, I was both sad and dissapointed. While I can admit that VS Code is a solid editor, my personal preference always leaned towards Atom. However, over time, Atom started to feel sluggish. I collected numerous plugins over the years and it began to weigh heavily on performance, not just during startup but also during regular usage....

The power of extensive command history in Bash and Zsh

I rely heavily on shell usage. For over 15 years, I was a devoted user of Bash until I discovered Zsh and made the switch. One thing that remained constant throughout my transition was my configuration to maintain an extensive commands history. This setup is replicated across all my systems. When you spend a lot of time coding, you often find yourself repeating commands or running variations of them. Remembering all these commands can be challenging, but with resources like Google and ChatGPT, it’s not always necessary....
