__mharrison__··on Pandas Should Go Extinct
Most folks just need to learn how to use pandas well and that will open enough doors. Then they can move to polars or duck if needed.
__mharrison__··on Pandas Should Go Extinct
I'm in the middle of wrapping up the edits for Effective Pandas 3rd Edition. (I also wrote a Polars book and just wrapped up a weeklong training session on pandas this week.)

Pandas is not perfect, it has a bunch of warts. But it is good enough for most. (And many of those folks are using Excel or tableau or power bi... These were the types I was training this week).

If you have medium data, migrating from pyarrow backed pandas to duck or Polars is trivial.

__mharrison__··on DaVinci Resolve 21.1
I spent a few tokens last year trying to create a Python lib for native (undocumented) Resolve files. I was making progress, but it was slow (I ended up scripting Resolve in different ways). I imagine that current models could reverse-engineer the native file format relatively quickly.
__mharrison__··on DaVinci Resolve 21.1
Highly recommend the studio version. The ability to edit by transcript is worth the price alone.
__mharrison__··on DaVinci Resolve 21.1
I thought DaVinci Resolve could automatically sync camera footage for a few years now. I did it about 4 years ago.
__mharrison__··on DaVinci Resolve 21.1
I had AI write a program to edit with resolve. It does transcription, looks at the transcript and decides where to make cuts. If does a decent job and saves me a bunch of time.
__mharrison__··on Ask HN: Resources to get good at soldering?
Build a keyboard. By the end you should be well aware with soldering (and how to remove parts that you put on the wrong side of the PCB).

Very cool. I was messing around vibe-coding an HR monitor on a LilyGo T5.

My thought was I'd love to set an HR zone and then connect it to my e-MTB and have it change power to keep me in a zone.

The refresh rate on my device was horrible, and the models (this was a few months ago) struggled to create a historical line plot of my HR.

__mharrison__··on Pre-Release of Polars 2.0
This is the way. Favor keyword arguments to alias.

__mharrison__··on Run Qwen3.8 27B locally: real numbers from my Mac Studio
This is a problem that Hugging Face could easily help solve.

Crawling through Reddit or forums to find the right incantation to run a model is frustrating.

__mharrison__··on M5Stack Launches PaperMono
Yes, I was wondering if this was the Gameboy (capable) hardware.
__mharrison__··on Nvidia agrees to acquire Hugging Face for $13B
The lowest hanging fruit that hf could offer is community monitored commands for running local models.

Right now it is a pain to find the correct incantation.

__mharrison__··on typ.ing
Why? They brought columnar lately to the mass(es).

Not sure why framework doesn't do this...
__mharrison__··on Why aren't smart people happier? (2022)
Thanks for sharing. Parenting is hard.

It sounds like you have found useful tools in adulthood.

__mharrison__··on AI boosted homework scores, then exam scores dropped: study
Yep, learning is hard work.

Would you have preferred another label? If so, which one?

__mharrison__··on Qwen 3.8 27B
As a MBP and DGX spark owner, I would love such a site... (Feel like it would be a low effort feature of hugging face).

Searching through Reddit and forums for best commands is annoying.

__mharrison__··on Marimo now runs in PyCharm
Not sure about this environment complaint with Jupyter.

I taught venv and pip for years without issues to thousands.

Now I teach uv and it is even faster and easier.

__mharrison__··on An Engineer's Guide to USB Typе-С (2024)
I generally stick magnetic USB C connectors into things like keyboards, phones, and iPads.

The slight bulge is worth the reduction in insertions. Also is very convenient for snapping when I need to connect.

__mharrison__··on Measuring Input Latency on Linux: X11 vs. Wayland, VRR, and DXVK
I need to look into this more. I was trying to vibe code an OBS plug-in just last week to measure sync between audio and video.

My system flashed the screen white and played a note. The idea was to have the camera detect monitor brightness and detect the offset from the audio note. I'm practice the brightness of a 40 inch TV didn't seem to impact the video of the insta 360 link webcam.

(I ended up vibe coding a Python GUI to quickly allow me to push through video frames and show the audio frequency. I could quickly type 'v' (video) where I clapped and 'a' (audio) where the waveform changed. It would then tell me the offset...

Serious question: what is a short prompt?

(For that matter at what point is it "long"? And does the rest of the context matter? Should it be short too?)

__mharrison__··on A better way to tie gym shorts (or any drawstring) [video]
The knot of called a "sheet bend". Great for connecting two different sized ropes as well.
__mharrison__··on How little exercise can you get away with?
Find something you enjoy doing, then "hack" it to make you participate more.

For example, I play a lot of ultimate in the summer. I play with a lunchtime pickup group, so there is a forcing function to play. I like to bike, and helping coach my daughter's high school mountain bike team ensures I get a lot more miles than I would otherwise. In the winter, I have friends that I ski with. I also enjoy exercising on my own, but some activities are better as a group.

When I worked in an office, I played a lot of ultimate (lunchtime pickup), but also would do walks with colleagues. Great way to combine debugging, learning, and exercise.
