thenobsta··on Shape typing in Python
Pandera helps with some of this. Check it out -- https://pandera.readthedocs.io/en/stable/

We've used it to great effect.

thenobsta··on Tai chi reduces blood pressure better than aerobic exercise
For computer work, I use a split keyboard. It allows me avoid internally rotating my shoulder. I highly recommend it. Split keyboards can be kinda expensive. It can be tested out cheaply by using a laptop and external keyboard -- left hand on the laptop right hand on the external keyboard. If you have a mac, I had to install karabiner to get keys from both keyboards to work in concert (e.g. to enable left shift and right 'k' to capitalize k).

Tai Chi and Cha?
thenobsta··on John Walker, founder of Autodesk, has died
I've been a happy reader of fourmilab.ch for years. His book reviews, the hacker's diet, and his other tools are one of the treasures of the internet. Not to mention his creation of AutoCad (a tool I loved in high school and college, after his time but I'm grateful none the less). RIP, John.
thenobsta··on Framework Laptop 16 Review
I get that. There's tons of amazing possibilities and it's fun to imagine them and to hope they come out. I'm going to try to make something with my kiddo for the FW, but of course the focus will be on bonding and helping my kiddo build skills, understanding, and connection. So we might not quite get to putting the e-ink reader on the backside of the lid.
thenobsta··on Framework Laptop 16 Review
Love it. I'm excited to upgrade the mainboard and to put the old board in a new shell or the cooler master case. We'll see what the kiddo wants to do.

Maybe she'll become a gamer and we'll get a 16.

Anyway, you've got my total support and $. I get that we're a niche market though. It would be great to see my non-techie friends sporting the Framework Gear -- I think they'd love the pre-built machine, but the messaging steers them to thinking it's only for DIY-ers. E.g. -- My sister would love the FW13 because she doesn't have special performance needs and cares about sustainability, but she got very intimidated buying an MBA, so guiding her through buying a Framework will be some work on my end (...messaging that would land for her would be that Framework solves all your basic problems (browsing, video-chatting, and netflix) and when you need more power you can upgrade for only the cost of the components).

thenobsta··on Framework Laptop 16 Review
I'll chime in and say that I love my FW13. It's a great machine. I got the DIY kit and had my 7yo put it together. It was straightforward with a little help from dad (even installing Ubuntu!). Now we fight over who gets to use it.
thenobsta··on An Overview of Nix in Practice
This seems like a bummer. I'm under the impression that one of the points of nix is to have pain free rebuilds. I wonder how to address this issue and what the source is -- is it a critical mass thing (more users/contributors solving problems)? or an issue arising from inexperienced module maintainers?
thenobsta··on Oh my poor business logic
Whoa, this is unsurprising, but surprising/unfortunate.

I'd love to read a tutorial of how mapping every business process is done in practice. Do you have any pointers?

thenobsta··on Software disenchantment
> which randomly bring this weird thought to my head, that the only human that does not do any mistakes any more is a dead one; perfection in human actions is only achieved in the absence of life... ok need to stop there

Love a good philosophical tangent! Wish you expanded :)

thenobsta··on A 1990 experiment to test whether we could discern life on Earth remotely
I always thought it would be a cool investigation to look at the distribution of entropy signals coming from celestial bodies and group them. I'd bet there is a non-'natural' entropic signal coming from planets with biological processes on them.
thenobsta··on Karaniya Metta Sutta: The Buddha's Words on Loving-Kindness
Small animals also help. :)

I can't help but feel happiness and goodwill for a cute cat or bunny. Once I have that feeling, I can pay attention to it, keep it going, sit with it, or wish that feeling for myself or to others. If I lose it, I just bring up an endearing image or thought of the cat/bunny/my kiddo and pay attention to that feeling again.

Big fan of TWIM. I've tried several methods and TWIM seems to work super well with my brain.
thenobsta··on Lessons from bootstrapped companies founded by software engineers
"Frank Chambers chose to forgo an investment of $500,000 which, if held until the stock price hit its 1987 high, would have appreciated to more than $37 million."

Oi, hindsight is great. The '87 high was about $3.50. ADSK is sitting at $210 today or $2.2B for that 500k investment.

thenobsta··on Intel to set its FPGA unit free to pursue its own path
Every time I see an FPGA article, I feel a little sad that Tabula[1] didn't make it -- 1.6Ghz clock and reprogrammable on the fly. RIP.

thenobsta··on A revelation about trees is messing with climate calculations
Are there correlation studies on this? I’m genuinely interested in reading about this.

Ha, this reminds me of Wiio's laws -- https://en.wikipedia.org/wiki/Wiio%27s_laws

This blog is about co-living with others. It seems a little more connected than you're looking for, but might have some insight nonetheless -- https://supernuclear.substack.com/
thenobsta··on The Ashley Book of Knots (1944)
Clifford Ashley was one of the last marlinspike seamen. What an encyclopedic knowledge of knots. I pull my copy out every now and then and just sit and tie knots and/or share useful knots with my kiddo.
thenobsta··on A Conversation with Renaissance Technologies CEO Peter Brown
This would check out as a winning strategy. If you figure how to remove this arbitrage out before anyone else, then you nobody else can replicate your strategies. Since they were early in the quant game, this seems plausible (though other things mentioned here also seem plausible -- insider trading, lots of brilliant people, etc).
thenobsta··on American megachurches are thriving by poaching flocks
UU sounds awesome. Their 4th principle, the “free and responsible search for truth and meaning” sounds particularly enticing when I think about what their sermons would be like. I’d expect the pastors to draw from an expansive set of sources to support that search.
thenobsta··on Ham radio enthusiasts vs. High-frequency traders: A battle for the airwaves
Agreed, the precedent set, if goes through, seems fraught and ripe for attempts at expanding the spectrum usage.

thenobsta··on Thoughts about what worked in math circles
~6 seems to be the right age. I tried with with my kiddo at 5 and with another kid when they were 5 with no success. A bunch of first graders, on the other hand, were quick studies.
thenobsta··on Thoughts about what worked in math circles
Huh, my daughter and I taught her first grade class SET last year (I did most of the pedagogy…). They seemed both able to learn it and engaged. It wasn’t in a math circle setting, but a lesson to the whole class. Would be cool to investigate the differences!
thenobsta··on Trying to become a better developer by learning more about aviation
I took a self-rescue course and a list at the end of their handout had such good engineering tips that I shared it with my eng team. Lots to be learned about engineering from climbing/mountaineering. The list was something like the following:

A few pro-tips:

- Slow is smooth. Smooth is fast.

- Simplicity/speed/efficiency is good.

- Strong is good. Redundancy is good/better.

- Equalization and Extension are a trade off.

- Not everything is a nail so NOT every tool is a hammer.

- Tools that have multiple uses are good.

thenobsta··on Augmented Reality Welding System
Like other comments, I agree that the technology leaves something to be desired. However, I learned welding from a community college in high school. I wasted A LOT of welding rod/wire and metal just getting the pacing and angles correct. I could imagine a tool like this helping someone grease the groove without so much wasted resources.
thenobsta··on Show HN: Silly math games to make learning fun for K through 3rd grade
Yeah! Go you! There's so many great lessons in this game -- arithmetic, probability, decision making, managing competing desires, risk and ROI (gotta bet some to get something back, and ultimately you might not get it back).
thenobsta··on Show HN: Silly math games to make learning fun for K through 3rd grade
The math and probability part could probably be made into a game. Something engaging and with a compelling end goal (candy or completion of a fun narrative) would catch her eye.

My goals for playing are more oriented towards bonding, learning useful/life lessons, and keeping the kiddo challenged.

thenobsta··on Show HN: Silly math games to make learning fun for K through 3rd grade
Awesome. Good on you! The kids are lucky that you organized one.

Edit: Just looked through your website. Love the math and the satire. Keep it up!
