Thoughts on Generating C
The article discusses six thoughts on generating C code, including the importance of understanding the target architecture, the benefits of using a high-level language, and the role of compilers in optimizing C code for performance.
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!

Information Is Beautiful
Data exfil from agents in messaging apps
The article discusses the potential for data exfiltration through URL previews, using the OpenClaw example to demonstrate how attackers can exploit this vulnerability to extract sensitive information from language models.
Sleeper Shells: Attackers Are Planting Dormant Backdoors in Ivanti EPMM
The article discusses the discovery of a vulnerability in Ivanti Endpoint Manager (formerly MobileIron) that allows attackers to plant 'sleeper shells' - persistent backdoors that can be activated at a later time. The vulnerability, which was patched by the vendor, highlights the importance of keeping enterprise software up-to-date to mitigate potential security risks.

Show HN: VillageSQL = MySQL and Extensions
INSTALL EXTENSION vsql-complex; CREATE TABLE t (val COMPLEX);
Look, MySQL is awesome [flamewar incoming?]. But the ecosystem has stagnated. Why?
No permissionless innovation. Postgres has flourished because people can change the core of the database (look at pgvector and pg_textsearch), without having to get their changes accepted upstream.
(This, btw, is what powered GitHub's early success: you can fork a repo and make changes without needing the owners' approval)
VillageSQL is a tracking fork of MySQL (open source, ofc) that adds an extension framework: * Drop-in replacement
* Add custom data types and functions (with indexes coming soon)
* we wrote example extensions (vsql-ai, -uuid, crypto, etc.)
* you have a better idea for an extension
* my CEO submitted a Show HN post but linked to the announcement blog; help me show him hackers want code first
* I'm particularly proud of the friendly C++ API to add custom functions (in func_builder.h)
That link again is https://github.com/villagesql/villagesql-server
(Oh, and I get to work with the former TL of Google's BigTable and Colossus, so we care about doing databases Right)
