ghgr··on Show HN: rStation – A shared research lab for your AI agents
If you're on Linux you can use lxc-box to quickly spin up containers and VMs. I made a wrapper that creates them, installs codex and shares directories with the host in a single command, using a docker-like syntax
ghgr··on Show HN: rStation – A shared research lab for your AI agents
Very exciting! I'm very interested in this space and I came across a couple of similar projects, like https://agent4science.org and https://agentpub.org. What's the main differentiator of rStation? It's great that there's variety here, although on the other hand it's causing fragmentation. I guess we'll end up needing "one universal standard that covers everyone's use cases".
ghgr··on When code is a maze, smart developers make maps (2025)
Very cool, thanks for sharing!

If, like me, you're trying to compile it, don't forget to set the

    -std=gnu89
flag in gcc, so:

    gcc -std=gnu89 -w -o maze maze.c
Then run it as:

    echo 10 | ./maze
ghgr··on A Million Falcons Went Missing. Here’s How They Were Found
They weren't "missing": GPS-tagged red-footed falcons revealed that they migrate to a tiny communal roost in central Angola (“Falcopolis”) each February–March.

There, saved you a click (disappointed on National Geographic for that clickbaity headline).

ghgr··on Nancy Grace Roman Space Telescope
Thank you! From talking to a contact working with JWST, it sounds a bit trickier in practice. The data are public, but with Roman the idea is that you must process them on their computers rather than download everything locally, and you pay for the compute/storage you use.
ghgr··on Nancy Grace Roman Space Telescope
> every observation is public as soon as it is processed with no embargo

That's a big deal. Do you have any source for that? (I couldn't find it in the ones you linked). This is great for humanity as a whole, but... poor grad students who now need to rush to publish their papers even sooner.

ghgr··on Mushroom behind 'tiny people' hallucinations identified
In case you're wondering like me, I think parent is referring to elephant skulls being mistaken for one-eyed, giant creatures.
ghgr··on Claude Opus 4.7
And not only in the LLM ecosystem. Flask was originally an April Fool's joke too.

ghgr··on It's OK to abandon your side-project (2024)
To be fair, these "others unfamiliar with the internal logic" can very well be yourself in six months.
ghgr··on The Miller Principle (2007)
As a counterexample, thanks to LLMs many long-form articles that get posted with clickbaity (but devoid of content) headlines that I would have ignored otherwise now get "read" (albeit indirectly, with the prompt "Summarize the insights of the article $ARTICLE_URL in an academic, dry, technical and information-dense way")
ghgr··on Telnyx package compromised on PyPI
I'd argue it's not only not inconvenient, but also a great way of keeping your system clean of all the random system-wide dependencies you'll end up accumulating over the years.
ghgr··on Show HN: Hacker News archive (47M+ items, 11.6GB) as Parquet, updated every 5m
I'd say it's less a usage dropoff and more a reversion to the mean after Covid
ghgr··on FFmpeg 8.1
> Oh there's a new version of ffmpeg, I'll just quickly build it from source... no I can't wait I'll download the binary

ghgr··on Bet on German Train Delays
Say you have to pick a flight and you take the train to the airport. You can bet your train will be delayed, so if it ever happens at least you'll get a payout.

An insurance of sorts, so to speak.

ghgr··on AI-generated replies are a scourge these days
You can just use the one in the page: https://tropes.fyi/tropes-md
ghgr··on Keybee: A Keyboard Designed for Smartphones
Incredible, we cannot drop the guard even for a second. Thank you for the heads up!
ghgr··on Keybee: A Keyboard Designed for Smartphones
There's https://simplemobiletools.com, who are doing their job to close that delta (not affiliated with them)
ghgr··on Man accidentally gains control of 7k robot vacuums
> [...] the same credentials that allowed him to see and control his own device also provided access to live camera feeds, microphone audio [...]

Sorry what? Why would a vacuum cleaner even need a microphone?

ghgr··on OpenCiv3: Open-source, cross-platform reimagining of Civilization III
> How far OSX has come since the days of the “cancel or allow” parody advert.

In case you're wondering like me, this is the advert in question: https://www.youtube.com/watch?v=8CwoluNRSSc&t=0

ghgr··on My ridiculously robust photo management system (Immich edition)
I'm like you, and a big fan of Pigallery2 precisely for its simplicity. But it turns out that Immich does support external libraries, so you can keep your manual file management in your filesystem and still use Immich for efficient indexing, face recognition, quick picture retrieval by year, location, people etc...

I'd recommend you try Immich (there's a docker compose version) and if you don't like it, you can just remove it and move on.

ghgr··on I'll pass on your zoom call
> If there's one that I really need to be on, I'm going to spin up a VM on my computer so that it has no idea of the other files laying around, such as my ~/passcodes.csv. If you are such a negligent bullhead as to get me onto your call, you'll be unable to see me because my VM cannot access my camera! By design! Same for my microphone, so I'll plug in a USB mic if I really need to speak up. More likely than not though, I'm exhausted by now. I'll spend the full duration of the call eeking a small echo of pleasure from the continuation of this rambling alarm, for your sheepish audience to rub their enablist shame in.

This is written in an edgy tone but it's pretty much SOP with QubesOS. Why would you install _anything_ in your main VM? Not just Zoom, but anything you import in a deep dependency graph can access your figurative ~/passcodes.csv anyway.

ghgr··on Two Concepts of Intelligence
I agree with Dijkstra on this one: “The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.”
ghgr··on Immich v2.0.0 – First stable release
Checkout https://bpatrik.github.io/pigallery2/. I've been using it for years and it checks all the boxes you're looking for
ghgr··on FreeDroidWarn
Serious question: can you point out some serious complaints? They seem to have an exhaustive justification for their reasons to only support Pixels, see https://grapheneos.org/faq#future-devices
ghgr··on Ask HN: What are you working on? (April 2025)
Main work: tokenization of real-world assets, but on the side I’m building two projects as a solo dev:

  - XRoll.io — a fully on-chain gaming framework on the XRP Ledger, inspired by SatoshiDice but built for compliance. Commit-reveal fairness (HMAC_SHA256(secret, bet_txn_hash)), full transparency on-chain. Integrated KYC, AML, self-limits at the protocol level. Frontend is optional; ledger is the source of truth.

  - Nexula — an evolutionary image generation system. Embeddings extracted with CLIP, clustered via HDBSCAN, visualized with UMAP. User behavior (time spent) drives fitness scores; top samples recombine through weighted interpolation to generate new images. Built on Django backend, session-based personalization without login.
Looking for like-minded people interested in exploring both the technical and business sides of these systems.
ghgr··on Barlow's Principles of Adult Behaviour
It's from 1977, so probably dinosaur hunting
ghgr··on Siyuan: Privacy-first, self-hosted personal knowledge management software
I can also recommend Trilium Notes [1], which I have been happily using for years. It's currently in "maintenance mode", which I personally see as a feature (no risk of bloatware).

Self-hosted, great webapp, optional native clients and works offline.

ghgr··on Don’t look down on print debugging
If you're using print debugging in python try this instead:

> import IPython; IPython.embed()

That'll drop you into an interactive shell in whatever context you place the line (e.g. a nested loop inside a `with` inside a class inside a function etc).

You can print the value, change it, run whatever functions are visible there... And once you're done, the code will keep running with your changes (unless you `sys.exit()` manually)

ghgr··on Numpyro: Probabilistic programming with NumPy powered by Jax
If you are struggling to understand the README, I highly recommend the book Statistical Rethinking: A Bayesian Course with Examples in R and Stan by Richard McElreath. Although the examples are in R, the same concepts apply to Pyro (and NumPyro)
