Ask HN: Favorite In-Depth Deep Dives

What are your favorite in-depth deep dives into a less-known topic, which is also something that can spark interest for a field? Non-computing preferred. I recently had the pleasure of stumbling over the following:The Story of Titanium - https://www.construction-physics.com/p/the-story-of-titanium - how it became useable.https://dynomight.net/p2p-meth/ - a deep dive into the recent history of...

Show HN: Seasons Come and Go – a calm overview of the natural rhythms around us

https://seasonscomeandgo.com/

A starting page focused on natural rhythms around us. A reminder that the earth keeps on turning, seasons are in motion and each day the sun has a slightly different arc across the sky.This was created as an excuse to try jj, almost exclusively through prompting claude to turn a vague vision into reality. All it took was part of my attention here and there across two days, while still...

Really appreciate the graphics, in-between summary elements and the progress bar widget. A bit too much colorful font variants my taste as it leans towards distracting, but hey everybody is different. That was a swell read, thanks for sharing!

As far as "app which helps create overview, reduce overwhelm and taks small steps" - I wonder how many of those are out there? I have written about 3 of those already for various use cases and in different flavors. Using them over a longer period of time, once the chaos subsides or the novelty wears off seems to be hard for me personally.

What would be an easier niche in your opinion?
Re:Ask HN: Anyone making a living from a paid API? on Saturday May 31, 2025 @11:14AM (#44144807)
I'm also curious about ways to provide value with a technical project.

The challenge when exploring this topic: the incentive to stay under the radar. Those succeeding don't have much to gain from sharing details here. Worst case: it could invite competitors into their space.

Communities that thrive on growth (e.g., open-source) tend to share freely, but API businesses, especially ones which are easy to execute, often guard their edge.

A recent finding I had, while not necessarily an API: services which help you 24/7 stream a lenghty video file. YouTube live streams seem to work well for those lofi-types of channels, and there are services which are built to enable autopilot live streams.

Good stuff. Thanks! Any chance this has to do with the generous grants which get bestowed on movies and tv productions in Canada?
Thanks for the reply! Never would have thought.
According to a HN post from 2015, Buenos Aires is the bookstore capital of the world. https://news.ycombinator.com/item?id=9747230

Ask HN: What Are the Global Capitals for Specific Industries or Niche Interests?

Curious minds of HN,I'm looking to learn about what the semi-unknown "capitals" of various industries or niche interests around the world are. These could be cities that serve as the hub, epicenter, or primary gathering place for a specific sector or community, whether mainstream or obscure.For example, I have the following (personal and not referenced) obvious examples in mind:- Finance = New...

Thanks for the suggestion!

Ask HN: CEO letters and similar sources of insight

I've had a great time reading founder/investor letters from Stripe [1] and Amazon [2] so far. Really interesting insights about a certain domains, articulated clearly and in a succinct fashion.Gumroad's public board meetings [3] offer a similar kind of look behind the scenes.What founder/investor letters or similar media (like in-depth podcasts) would you recommend to read to get deeper insight...

Re:Go Enums Still Suck on Thursday March 28, 2024 @08:36AM (#39850479)
That's the reason why I chose to focus on Go instead of Rust after immersing myself in it for a while.

Rust invites you to aim for brevity and crafting smart solutions whenever you can. Don't get me wrong, sometimes this leads to beautiful code. It can be super satisfying to write. But there is only so much fun in reading yet another 10-step iterator method chain which works due some arcane edge case in the middle of it.

I vastly prefer reading dumb and obvious Go code. It's just easier to understand and to work with.

Re:Docker Arg, ENV and .env – A Complete Guide on Tuesday August 08, 2023 @01:22PM (#37052507)
Thanks for the kind words! I'm currently revising some old articles and getting back into writing more often, this is a nice reminder to keep at it.
Thanks a lot for sharing! I ended up watching the referenced "It's Time for Operating Systems to Rediscover Hardware" talk as well. Fascinating stuff.
Way out of my depth! However, the stuff I saw the folks from Oxide [1] talk about comes to mind. Hardware stuff with Rust. If you want to look at a specific project, Hubris [2] is a kernel for "deeply-embedded" systems.

[1] https://oxide.computer/blog/building-big-systems-with-remote...

[2] https://github.com/oxidecomputer/hubris

I wondered about an adjacent topic recently ("what IS the kernel actually") and found out that a great way to understand it, would be to start with the boot process. Once I felt less lost, I tried to capture my learnings [1]

The text is not edited yet, but as I had the benefit of learning about it with fresh eyes, it should be very approachable (and hopefully accurate enough)

The site was built with Next.js and TailwindCSS in about a day. The size is quite big, because data is baked-in, for that sweet sweet quick interactivity.

"Liked", "watched" and similar annotations are only saved on your local device. "Look, no server ma!"

Hope this helps some of y'all to find one or two interesting JRE episodes you haven't stumbled over yet.

Re:The Best of Edw519 - A Hacker News Top Contributor on Tuesday September 07, 2021 @04:08AM (#28442251)
Interesting! Reminds me of James Clear and the way he used blog posts as raw material for his book.

PKM geek-out time: Edw519 has been using HN as a tool for thought. Producing intermediate packets in the form of comments. If those comments were more interlinked, it would be closer to a Zettelkasten.

Hi HN! First time I see one of my articles on here. What a nice surprise.

At long last, winter is coming.
Whoops, sloppy generalization on my part. You're completely right of course, thanks! I've been focusing on deep learning a lot lately, to the point where AI has become an alias for those exciting new GPU-heavy techniques.
The results are really impressive. At the moment I'm considering spending a low 3-figure amount for a professionally spoken intro for a new podcast. Some of the lines I generated are in my top 5 easily, human speakers don't have a lot of edge for short generic blurbs of text anymore it seems.
Yeah, running anything related to AI involves GPU instances. An alternative is to point people to using Google Colab where you can get access to a GPU for free, but that's not a smooth end user experience for most folks.
Re:Dockerfile Best Practices on Sunday January 03, 2021 @09:43AM (#25622027)
Shameless plug: if you want to learn more about building better Docker images (beyond using hadolint, which is an excellent quick win) I put together a comprehensive free email course about that topic over at https://vsupalov.com/courses/
Re:Dockerfile Best Practices on Sunday January 03, 2021 @09:41AM (#25622013)
+1 for hadolint. There's also https://github.com/goodwithtech/dockle and https://github.com/aquasecurity/trivy if you want more security emphasis.

For those who want to like Hugo, but can't stand the templating language: there's also Zola (https://github.com/getzola/zola), a superb static site generator, with built-in Sass compilation, written in Rust.
