AI makes the easy part easier and the hard part harder
This article explores the impact of AI on the ease and difficulty of various tasks, noting that AI can make simple tasks easier but may also increase the complexity of more challenging problems, thereby making the 'hard part harder'.
GitHub is down again
The article reports on an incident that caused a widespread outage of GitHub services, affecting users globally. The incident was caused by a network configuration change, which the GitHub team worked quickly to identify and resolve to restore normal service.
AI fatigue is real and nobody talks about it
The article discusses the phenomenon of 'AI fatigue', where people become overwhelmed and disillusioned with the rapid advancements in artificial intelligence technology. It explores the potential causes of AI fatigue, such as unrealistic expectations, lack of understanding, and concerns about the societal impact of AI.
Slop Terrifies Me
The article explores the author's fear and discomfort with the rapid advancements in artificial intelligence (AI), particularly the emergence of AI-generated content known as 'slop', which can be indistinguishable from human-created work. The author expresses concerns about the potential impact of AI on creativity, authenticity, and the future of human expression.
Show HN: Algorithmically finding the longest line of sight on Earth
We're Tom and Ryan and we teamed up to build an algorithm with Rust and SIMD to exhaustively search for the longest line of sight on the planet. We can confirm that a previously speculated view between Pik Dankova in Kyrgyzstan and the Hindu Kush in China is indeed the longest, at 530km.
We go into all the details at https://alltheviews.world
And there's an interactive map with over 1 billion longest lines, covering the whole world at https://map.alltheviews.world Just click on any point and it'll load its longest line of sight.
Some of you may remember Tom's post[1] from a few months ago about how to efficiently pack visibility tiles for computing the entire planet. Well now it's done. The compute run itself took 100s of AMD Turin cores, 100s of GBs of RAM, a few TBs of disk and 2 days of constant runtime on multiple machines.
If you are interested in the technical details, Ryan and I have written extensively about the algorithm and pipeline that got us here:
* Tom's blog post: https://tombh.co.uk/longest-line-of-sight
* Ryan's technical breakdown: https://ryan.berge.rs/posts/total-viewshed-algorithm
This was a labor of love and we hope it inspires you both technically and naturally, to get you out seeing some of these vast views for yourselves!

I am happier writing code by hand
The article discusses the author's preference for writing code by hand rather than using a computer. It highlights the benefits of this approach, including better focus, creativity, and a more enjoyable coding experience.
Claude’s C Compiler vs. GCC
This article compares the CCC (C Compilers Collection) and GCC (GNU Compiler Collection) compilers, discussing their features, performance, and suitability for different use cases. It examines the strengths and weaknesses of each compiler to help readers choose the most appropriate one for their software development needs.
Another GitHub outage in the same day
GitHub experienced a major service disruption, leading to widespread outages and degraded performance for its platform. The incident was caused by a significant network incident, and GitHub worked to restore services as quickly as possible.
I put a real-time 3D shader on the Game Boy Color
The article explores the development of a new real-time global illumination technique called 'GBShader', which aims to provide realistic lighting in 3D graphics while maintaining high performance. It discusses the key features, technical details, and potential applications of this rendering technique.
Nobody knows how the whole system works
The article discusses the inherent complexity of systems, where no single individual or group can fully understand how the whole system works. It highlights the importance of recognizing and managing this complexity, rather than attempting to impose simplistic solutions.

Show HN: I created a Mars colony RPG based on Kim Stanley Robinson’s Mars books
I built a desktop Mars colony survival game called Underhill, in homage to Kim Stanley Robinson's Mars trilogy. Land on Mars, build solar panels and greenhouses, and try not to pass out during dust storms. Eventually your colonists split into factions: Greens who want to terraform and Reds who want to preserve Mars.
There’s Chill Mode for players that just want to build & hang, and Conflict Mode that introduces the Red v. Green factions. Reds sabotage, the terrain slowly turns green as the world gets more terraformed.
Feedback welcome, especially on performance and gameplay!
GitHub Agentic Workflows
The article discusses GitHub Actions, a powerful workflow automation tool that allows developers to create custom software development workflows directly within their GitHub repositories.
