mcbishop··on Advanced Rail Energy Storage of North America
I'd love to see an unbiased financial-analysis comparison: this vs. hydro vs. electrochemical.
mcbishop··on The future of software development is software developers
I think the heavy investor subsidization / speculation makes this different. The high cost of early 1Tb flash drives was largely borne by buyers.
mcbishop··on The future of software development is software developers
The parent comment's point is that we _should_ care because cheap frontier-model access (that many of us have quickly become hopelessly dependent on) might be temporary.
mcbishop··on Can “second life” EV batteries work as grid-scale energy storage?
Right, $200-300/kWh is more the range for ~16kWh residential stationary energy storage systems.
mcbishop··on Puerto Rico's Solar Microgrids Beat Blackout
Net metering is gone in most of California (for new solar). I think it's going away in general. Distributed solar supports a more stable grid for everyone (per UL 1741-SB requirements).
mcbishop··on Puerto Rico's Solar Microgrids Beat Blackout
You can run sans grid with Enphase (with their "system controller").
mcbishop··on Ask HN: What are you working on? (April 2025)
Thanks so much! I do plan to open-source it. ...Once it's tightened up. Please email me if you'd like to be on a beta list. mike at bishop dot wtf
mcbishop··on Settling the File Structure Debate
tl;dr from the bottom of the blog post:

> Type-based grouping is great for tech-focused tasks, consistent naming, and large sweeping changes.

> Context/process-based grouping shines for domain clarity, team ownership, debugging, and mapping business problems directly to code.

mcbishop··on Ask HN: What are you working on? (April 2025)
Your comment made my day, thank you :)
mcbishop··on Ask HN: What are you working on? (April 2025)
A framework for Excel spreadsheets, written in Excel VBA. A nine-minute demo video is here: https://www.cabin.wtf (the file is 4mb, not 4kb)

If nothing else, this shows that the Excel UX can be radically changed thru one small Excel file... so much of the object model is exposed to VBA.

mcbishop··on The School Car Pickup Line Is a National Embarrassment
We park on the other side of a city park from my daughter's school. ...The five minute walk thru the park together is a highlight of my day.
mcbishop··on Solarpunk
I came across shademap.app a ~month ago, and had a "the internet can be so awesome" moment. I wrote to my property mates: "I found a cool free website for seeing shade at our site throughout the day and year. Maybe helpful for garden planning. Our address is loaded in [here]". Reply: "Wow! That is cool!". It seems to be very much in the solarpunk spirit (even more so with your engagement here). I hope to incorporate it into my solar installation work. Thank you :)
mcbishop··on Ask HN: Has anyone tried alternative company models (like a co-op) for SaaS?
I recommend the book: Reinventing the Organization. It has case studies of alternative models around the world.
mcbishop··on How we made our AI code review bot stop leaving nitpicky comments
My comment here got two downvotes. I was trying to contribute positively to the conversation. I've barely ever downvoted anyone. I upvoted the parent comment even though I disagreed with it (because I appreciated the perspective). The drive-by downvoters in HN bum me out.
mcbishop··on How we made our AI code review bot stop leaving nitpicky comments
Some have a smaller tighter codebase... where it's realistic to pursue consistent application of an internal style guide (which current AI seems well suited to help with (or take ownership of)).
mcbishop··on Engineer's solar panels are breaking efficiency records
Volts is an awesome podcast for energy-transition enthusiasts.
mcbishop··on Engineer's solar panels are breaking efficiency records
> If it were true free market forces would already gone 100% solar

EVs might be cheaper than ICE cars now (including energy expense over their expected lifetimes)... But that doesn't mean the free market should be 100% EVs (all of a sudden).

mcbishop··on Decade of the Battery
But there's still the possibility of combustible off gassing with LFP.
mcbishop··on Decade of the Battery
Yes, it's fully integrated and UL listed.
mcbishop··on Woman set up a table to share her collection of washers. Nothing was for sale
If you're new to building things that involve washers, and she's happy to teach the nuances of different washer types... that's helpful and awesome!
mcbishop··on Ask HN: Why are comments here overwhelmingly critical?
> The interesting question is, what factors mitigate this?

One thing is to foster a culture where substantiation is expected in negative responses (and downvotes) (i.e. we expect a genuine effort to support a different perspective). I've never downvoted, but the lazy drive-by criticisms always tempt me.

mcbishop··on My Dinner with [Marc] Andreessen
I definitely don't agree with everything he says, but I really appreciate the clarity and creativity in his thinking (in talks with Lex Fridman, Jordan Harbinger, Joe Rogan, Dwarkesh Patel).
mcbishop··on The reason PG&E rates are skyrocketing in California
In a case where the monthly grid-connection fee is exorbitant... ideally someone can get their off-grid system permitted by the city (to verify that it meets minimum requirements).
mcbishop··on The reason PG&E rates are skyrocketing in California
> On March 27, an administrative law judge published a proposed decision that, if approved in May, will impose a new fixed $24.18 monthly charge on residential customers not eligible for low-income discounts.

To not only end solar net metering but then to have a significant charge even for low-import solar/battery sites... ugh. I hope this doesn't go through.

mcbishop··on Many in Gen Z ditch colleges for trade schools. Meet the 'toolbelt generation'
An apprentice gets low pay in exchange for on-the-ground learning, and earning hours towards licensure. ...Paying ones dues, to eventually earn good income.
mcbishop··on Bayer is getting rid of bosses and asking staff to ‘self-organize’
There's strong structure with holacracy. There's a hierarchy of roles / responsibilities. It seeks to mitigate parallel informal power dynamics. Consider reading the book.
mcbishop··on Getting the Grid to Net Zero
> You're oversimplifying. US residential power is currently supplied by a pair of 120 V wires, but most of the stuff in your house only uses one leg of that pair. That's alright because it's AC, and the ground wire doesn't actually need to carry any significant current. Power just returns time-lagged through the same wire when the voltage changes.

This isn't how it works.

mcbishop··on Show HN: My $1k self-install, off-grid solar backup build for renters
NEM 3.0 isn't net metering. It's net billing, where exports get credited at wholesale rates.
mcbishop··on Show HN: My $1k self-install, off-grid solar backup build for renters
Net metering is no longer available in PG&E territory.
mcbishop··on Show HN: My $1k self-install, off-grid solar backup build for renters
I think this is single phase. 230V is a common single-phase voltage outside North America.
