drfunk··on Show HN: I built a tiny camera that knows where it is
"The camera knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation."
drfunk··on A game where you're an OS and have to manage processes, memory and I/O events
sounds a lot like a tweet from the parody account @PeterMolydeux !
drfunk··on Scientist creates 'mini‑universe' to measure time without a clock
Rick-and-Morty-esque title
drfunk··on Private AI for Original Thinkers
In my head I read "okara.ai" as "okarai", which sounds an awful lot like "o caralho" in Portuguese, and I had a good chuckle out of it...
drfunk··on Lights (at sea): See every lighthouse across Europe on an interactive map
Very cool, I thought about building exactly this a few months ago! Glad to see someone did :)
drfunk··on The Engineering Behind Fast Analytics: Columnar Storage Explained
Very good summary / starting point to better understand what makes OLAP databases get far better performance than OLTP DBs on analytical tasks!
drfunk··on Bank transactions cleared by FTP-ing files
Started reading the thread, and stopped because I realized I was hyperventilating
drfunk··on Mom of child dead from measles: "Don't do the shots," my other 4 kids were fine
Of course she's doubling down. Anything else would mean facing the extent of her responsibility in the death of her child, which would be absolutely crushing to her ego and self-image as a parent. She's protecting herself psychologically, that's not surprising.
drfunk··on Get Better Results by Asking the Right Questions
Looks really interesting! I've been looking for resources on how to ask better questions, it'll surely come in handy. I wonder if there's a PDF / single-file version somewhere, for easier consumption on e-readers?
drfunk··on Stingray machine vision software and high-precision laser kills fish parasites
Wtf that's incredible
drfunk··on I made a site that teaches languages using AI
Ha! I went through half of the Turkish course but stopped around two years ago, thanks for the reminder, I resumed my progression! I'll be looking at the new courses too :) And thanks a lot for making all of this work available to all!!
drfunk··on Macquarie Dictionary names 'enshittification' as 2024 Word of the Year
One point for Cory Doctorow!
drfunk··on Yemen's 'uninhibited' attacks push French warship to exit Red Sea
Worth noting that the article dates back from April
drfunk··on Ask HN: How do you track your work contributions effectively?
Use a journaling app, and write a few notes on what you did everyday. Each week, write a summary, grouped by topic: on project A, did 3 MRs, assisted pre-sales team on product X... At the end of the quarter, review the weekly summaries. Done.

I've been doing a version of this for the past 14+ years. Every manager I've had always told me I have the most detailed yearly review. It's been invaluable to me, as my work has usually been very fragmented on different topics / activities.

drfunk··on ML Code Exercises
Nice project! I have a few qualms with the instructions (sometimes misleading or unclear) and the implementation. For instance some problems fail, because 0. is considered different from 0.0

Using np.testing.assert_allclose in your asserts would solve this I think (https://numpy.org/doc/stable/reference/generated/numpy.testi...).

Happy to contribute / elaborate if you think it's be useful! :)

drfunk··on Show HN: Tesseract Doing Double Rotation
Nice work, I really like it! Do you plan on adding a small explainer as a blog post? That would be neat!
drfunk··on How Useful Are Interns?
Mostly good for talent pipeline imo. I try to look for curiosity and autonomy when interviewing prospective interns. That way I can let them explore cool topics that we don't have the bandwidth for. Bear in mind that (at least where I'm located) they are still students / in the middle of their training. They require more supervision than new employees. I consider this to be a plus, for instance if you want one of your team member to level up in coaching/management skills.
drfunk··on Ask HN: Keeping Up with Medical Developments
I find that most nice resources are paywalled unfortunately... (commenting to hopefully get pointers)
drfunk··on Ask HN: Estimation/planning tools that support confidence intervals?
You can play with Guesstimate, a spreadsheet-like tool handling uncertainty.

Here's an example of estimating the duration of a task (shopping): https://www.getguesstimate.com/models/19512

drfunk··on How do I relearn mathematics for machine learning?
3blue1brown's visualizations made a lot of things click for me, years after learning algebra and calculus. In my opinion they're the perfect companion to a more formal study with textbooks.

drfunk··on Ask HN: Looking for applications that allow collaboration without authentication
Excalidraw is good when you need a virtual whiteboard. No login required, so I've used it a lot for remote job interviews.
