What Hacker News says?
Mine is https://chollinger.com/blog/ . I write about fun tech challenges, mostly centered around the "Big Data" and "Data Science" world, even though last year, I've done a bit more hardware and random stuff. I only post every couple of months or so, because every article takes me quite a while to write (as they are typically small side-projects) - everything that has code has a Github repo attached, so whatever I r…

HN discussionI have done the same with Hugo on my blog[0], but actually had to fork an existing theme to remove what I would call bloat.[1] The interesting thing for me is, while I personally certainly feel the "need for speed" and appreciate pages like yours (nothing blocked, only ~300kb), most people do not. Long loading times, invasive trackers, jumping pages (lazily loading scripts and images), loading fonts from spyware-CDN…

HN discussionI've hosted my own website[0] and blog[1] for a while, but objectively, publishing a single article to medium - which i usually loathe - drastically increased my visibility. Using DDG to search for my name, my website shows up as 3rd result, whereas on Google, the only reason I'm even on the first page is because I was published on Towards Data Science. So using one of the big players was the only realistic way to g…

HN discussionSometimes I wonder whether going the "homelab" route would have been easier/cheaper for me. I built my server a couple of months ago, from scratch.[1] However, being forced to use a proprietary tool (ssacli) and limited drive compatibility do not sound desirable. This seems like an odd limitation - is this a normal thing with these types of projects/machines? [1] https://chollinger.com/blog/2019/04/building-a-home-s…

HN discussionYes. I like _writing_ because it's an effective way of learning (at least for me), since explaining something is very different than "just" doing something. I don't track visitors/analytics on my blog, so I don't really care how many people read it, but it forces me to dive just a little bit deeper into topics than I usually would for side projects and experiments. I also have no problem admitting if I misunderstand…

HN discussionThat's what I do with my website[0] as well (just on nginx and with vim via SSH). However, something that requires more functionality - syntax highlighting, tags, version control, easier deployments - I recently switched to Markdown + Hugo. [1] I find it all to be very subjective. The above author clearly favors TypeScript and React, and for a personal blog, I see nothing wrong with slightly over-engineering it. His…
