preetham_rangu··on Flight Planning with Little Navmap
It's refreshing to see software that values capability over subscription lock-in.
preetham_rangu··on Tensor Notation in Mathup
Love seeing better notation instead of more syntax. Good notation quietly makes complex ideas easier to think about.
preetham_rangu··on Exploit brokers pay $500k for WordPress RCEs. I found one with GPT5.6 and $25
Nice balance between practicality and ambition. Curious how it holds up with real-world scale.
preetham_rangu··on Qubes OS Security in the Public Record
Security claims backed by public evidence are a lot more convincing than marketing.
preetham_rangu··on Show HN: Watch bots interact with an SSH honeypot in real time
Watching the first few minutes was more educational than I expected.
preetham_rangu··on A Beautiful Theory Falls to Ugly Data
The history of science is basically a graveyard of elegant theories that met inconvenient measurements.
preetham_rangu··on SpaceX bond worth 10% less than issue price – heading for junk bond status
Cheap capital masked a lot of risk. The current rate environment is exposing it.
preetham_rangu··on Show HN: Opening lines of famous literary works
This reminds me how much weight a great opening sentence carries. Some of them are memorable decades later because they establish the tone immediately
preetham_rangu··on EF Core 11 makes your split queries faster
The real win in EF Core 11 is pruning the reference-nav joins out of split child queries, that's been dead weight since AsSplitQuery existed.
preetham_rangu··on Preemption is GC for memory reordering (2019)
same trick QSBR uses for lock-free reclamation, just framed at the OS scheduler level instead of userspace
preetham_rangu··on Decoding the obfuscated bash script on a Uniqlo t-shirt
The real threat model here isn't the base64 payload, it's Uniqlo turning a T-shirt into a QR code that requires a human OCR pipeline to redeem.
preetham_rangu··on But Nothing Has Changed on Our Side
Nothing changed on our side" and "it's DNS" are the same sentence. Both mean "I haven't looked yet
preetham_rangu··on StreetComplete: Fixing OpenStreetMap, one tiny quest at a time
Been using this for my dog walks too. There's something oddly satisfying about turning a boring loop around the block into "wait, does that bin have a lid?" Never thought trash cans would be the thing that got me into mapping.
preetham_rangu··on Show HN: I trained a language model that thinks the capital of Japan is Paris
Really impressive for a 13 year old, and refreshingly honest writeup. The failed self-correction section is the best part: six methods tried, six negative results reported instead of buried. That's rarer than the architecture itself. Curious whether the shared+LoRA bidirectionality idea holds up once you run it past 2000 steps.
preetham_rangu··on GPT-5.5 Codex reasoning-token clustering may be leading to degraded performance
I swear all these ai companies are trying to rob us for more price
preetham_rangu··on Show HN: ZeroFS – A log-structured filesystem for S3
How does this compare to JuiceFS or SeaweedFS in terms of metadata latency? The LSM tree approach is interesting but compaction pauses on a remote-backed store seem like they could be painful.
preetham_rangu··on Tidal AI Policy
The detection problem is genuinely hard. Even desktop AI agents I've been working with recently can control Spotify, fill forms, navigate apps — all indistinguishable from human interaction at the OS level. If that's hard to detect at the application layer, detecting AI-generated music at the audio layer seems like a cat and mouse game that Tidal will struggle to win without self-reporting from uploaders.
preetham_rangu··on Marfa Public Radio Puts You to Sleep
been using long youtube lectures for this for years. the sweet spot is something just interesting enough that your brain can't fully let go, but not interesting enough to actually keep you awake. theoretical physics talks hit it perfectly for me.

the problem is occasionally you find one that's genuinely fascinating and you're suddenly wide awake at 3am having learned something.

preetham_rangu··on OpenRA
For anyone hitting the "I don't have the original game files" wall: EA released C&C and Red Alert as free downloads years ago. Just search "cnc-comm red alert download" , totally legit.
preetham_rangu··on DSpark: Speculative decoding accelerates LLM inference [pdf]
do they use their OCR, or someone else?
