I didn't realise I had 2 entries in the top 20…

My attention tends to navigate towards "Show HN" posts when I'm browsing HN. There's quite a few who actually use Bulma: Divjoy, Sinous, Open-Registry, Pino…

I'm really amazed by those hacking articles, like the retro video game console [1] or sorting 2 metric tons of Lego [2]. I've also come across very useful tools that have saved me lots of trouble, like this automatic subtitle synchronizer [3] or this iTunes replacement [4].

My favourite will still be "Spot the Drowning Child" [5], so incredibly useful.

I analyzed 10 years of Hacker News data (2016-2025) to track Show HN submission trends.

- Show HN posts went from ~900/month (2016-2019) to 3,315 in Dec 2025

- Share of all stories: 2.4% (2016) → 12.8% (Dec 2025)

- Notable spikes: COVID-19 (2020), AI boom (2023), and accelerating growth through 2024-2025

Data source: HackerBook (144k Show HN posts / 3.4M total stories)

Lots of positive feedback here, but after a quick listen, I'm not a fan. To summarize my thoughts...

1. The experience just feels too sluggish. For example, I opened the HN homepage, skimmed all of the headlines, read the comments on the top post, and it probably took about 30 seconds. I was done, feeling like I got all the information from HN that I needed, with t

I didn't recognise the top story ( about cannaboids ) at all.

I then went to "past" and nothing from yesterday.

I then realised this site is based off the current front-page.

So I forced the "past" page to be today, and it's the third result: https://news.ycombinator.com/front?day=2026-03-16

But it's not on my actual front-page.

So this must have been done at a very brief window when this story was top, which even hnrankings didn't capture: https://hnrankings.info/47393619/

I found some Show HN posts. Let me now search specifically for the best/popular Show HN posts in the last 24 hours. From the results, I can see:

1. Show HN: Zeroboot – sub-millisecond VM sandboxes using CoW memory forking (4 points, 1 hour ago)

2. Show HN: Oxyde – Pydantic-native async ORM with a Rust core (143 points, 18 hours ago)

3. Show HN: Thermal Receipt Printers – Markdown and Web UI (104 points, 17 hours ago)

4. Show HN: Drakkar.one – Google Maps embed replacement (5 points, 2 hours ago)

5. Show HN: Droeftoeter, a Terminal Coding Toy (27 points, 9 hours ago)

Now I'll dig into the top performers to pull summaries for each one.

I'm filtering these results by recency and engagement, focusing on items posted within the last 24 hours that have gained meaningful traction.

For the posts within the 24-hour window, I should pull together summaries of the highest-performing ones. I notice that Thermal Receipt Printers returned a 404 on GitHub, so I'll exclude that and focus on the projects with solid engagement and accessible links.
