mmaurizi··on We discovered a new variant of Super Mario Bros
You get some inter generational nostalgia going on - I inherited my grandmothers NES which I have fond memories of playing any time I visited her.

I don’t play it as much as she did (I have modern games in my backlog to play as well) but I do occasionally buy more NES games to add to the collection.

mmaurizi··on Most people can't juggle one ball
For those who want to find other jugglers to practice with, there are lots of juggling clubs all over: https://dev.juggle.org/events/clubs.php

In my experience most folks go to clubs in order to do pass juggling with others (or because it’s a nice indoor space with high ceilings), but typically folks are very happy to spare some time to help beginners learn

mmaurizi··on I wish my web server were in the corner of my room (2022)
Why not use DDNS?
mmaurizi··on Electric cars produce far less brake dust pollution than combustion-engine cars
Ships are actually much more fuel efficient than trucks, by weight/volume.

Saying it must be inefficient because it includes ship transit instead of trucking "locally" is innumerate.

mmaurizi··on Ask HN: US expats/nomads, how do you find remote-out-of-US jobs in US?
At a past company, the two hires we made in this situation were people who were contributing to open source projects we maintained, who we hired to work on that project, so we knew they would be a very good fit.
mmaurizi··on Tesla suffers worst quarter since 2022 as deliveries tumble
They also have had no new recent models for years except for the Cybertruck, which is reportedly not selling
mmaurizi··on The Frontend Treadmill
Design shouldn't be part of front end engineering - there is a reason there is a separate role for that, designer.
mmaurizi··on A rent-stabilized 1 bedroom apartment for $1,100 In NYC? broker's fee is $15K
The people maintaining your building need somewhere to live, so unless they're in a rent-controlled unit themselves your maintenance costs will rise at the same rate as housing costs, as they're primarily labor.
mmaurizi··on Hertz to sell 20k EVs in shift back to gas-powered cars
They work with standard power outlets, just very slowly. Our Hyundai gets 50 miles of range every 24 hours its plugged in at home.

Mostly I charge at work not at home, which uses 240v power (think an electric dryer), and that can charge the car fully in 8-10 hours.

mmaurizi··on Heat pumps, more than you wanted to know (2023)
The piece you're missing, beyond just "gas is cheap", is that increasing the heating capacity of a heat pump costs lots of money when installing it, whereas increasing the capacity of a gas boiler isn't much more expensive during installation, but costs loads more when running it.

So technically it would be possible to install a heat pump with the same capacity as the existing gas boiler, but it would costs a ton more and it would all be upfront.

mmaurizi··on I visited over 120 EV chargers: why so many were broken
Tesla removes a lot of potential points of failure - no credit card machine or touchscreen to break and the cord is too short to drive over it with your car.
mmaurizi··on Panama Canal is so congested that one ship owner paid $4M to skip the line
Your info is about... 20 years out of date?
mmaurizi··on Heat pumps can't take the cold? Nordics debunk the myth
If you need a lot more heat than cooling, you can't just get a larger system, you have to also go from single-stage to 2/multi stage or inverter-based, so that you can scale down in the summer so you don't cool too quickly and not dehumidify enough.
mmaurizi··on Visualizing American inflation across eight categories
Inflation numbers are nationwide, but bay-area housing prices are not. And high housing raises the costs of all labor-intensive services (like your McDonalds), since employees need somewhere to live.
mmaurizi··on Heat pumps show how hard decarbonisation will be
I did this recently when replacing our failed central AC, it was an extra $500 over the AC. It’s tied into the existing natural gas furnace.

The main issue is your basic 14 SEER heat pump needs larger capacity to be able to be the sole heating source than it does for just AC, so in my case in the northeast US the heat pump can’t economically be run in Winter, just spring/fall & probably can’t keep up with the coldest winter days at all. But it does provide flexibility if gas prices spike in the future, and saves a very small amount of money per year (< $100)

If you’re the type to buy a high efficiency system going with a heat pump over central AC seems like it’s maybe more worth it from a return on investment standpoint

mmaurizi··on Automatic emergency braking should become mandatory, feds say
The Ioniq 5 is an EV, can't imagine the engine failures on their ICE cars will have any effects.
mmaurizi··on I’m ready to trade in my electric car
Financially for swapping to make sense, I think you need to be renting the batteries from the swapping company, not own them as part of the car purchase.

I think Renault used to do something like that?

mmaurizi··on EU countries approve 2035 phaseout of CO2-emitting cars
I would think an electric car would pair really well with off-grid solar - you can charge the car with excess energy during the day, and pull from the cars battery for power at night.

Sure it's a big power draw, but you can significantly downsize your battery system, which is presumably also a big power draw.

Or do you not have a big battery system now, and only run the high energy appliances like the oven during the day when you have lots of power?

mmaurizi··on Amazon will require employees return to the office 3 days a week
One of the places I interviewed at a few months ago said they were planning to enforce a hybrid work schedule "after Apple does". Apple does not have an office in or near our city.
mmaurizi··on Amazon will require employees return to the office 3 days a week
I'm fine with choice but I'd like to see it on a team-by-team basis. As someone who likes working in person with other folks at least some of the time, that doesn't really happen in practice if everyone can decide to work from home whenever they want on any given day.
mmaurizi··on EV batteries alone could satisfy short-term grid storage demand as early as 2030
Not just seasonal, the school busses are also not in use during the day while school is in session, which is unusual for mass transit busses.
mmaurizi··on Heat pumps of the 1800s are becoming the technology of the future
We run our steam humidifier just fine on 120v, but we have a relatively small townhome at 1400sqft
mmaurizi··on Why Not Mars
It may not be biologically possible for those who grew up on a low-gravity planet like Mars to emigrate to a higher-gravity one like Earth.
mmaurizi··on SBF Arrested by Bahamian Authorities
You're aware that control of the House of Representatives is still Democratic because the new Congress isn't sworn in until January right?
mmaurizi··on Hydrogen production from the air
Likely when built the streetlights weren't LED, so the buried cables are under-capacity. Assuming they can provide 230v power at 15-20 amps, that's enough to fully charge something like a Tesla or Chevy bolt (250-300 mile range) overnight.

Most people could do fine with charging only 1 out of every 4 nights for regular commuting, the tricky part is just figuring out how to make that work logistically, but it is at least feasible. Those with schedules that allow charging during the day make things easier I'd assume.

mmaurizi··on Building future cities out of timber could save 100B tons of CO2 emissions
How cold is "very cold" to you? There are air-source heat pumps that work all the way down to -15F now.
mmaurizi··on U.S. annual inflation rate drops to 8.5%
Thats... extremely pessimistic. I have a VW eGolf, with our 7.6kW home charger it can go from empty - full in 4 hours. It has a 36kWhr battery w/ a range of 150 miles, so in 30 minutes that's on average a little under 19 miles (probably more because you get faster charging at first and slower when closer to full).

But more to the point, how many people have a regular commute, only have street parking at home, and ALSO couldn't be expected to have their employer provide charging at work? Are they doing on-street parking at work as well?

I know a lot of folks in the city who own a car but use it for errands and trips but not commuting. They're the people best served by slower charging at grocery stores, movie theaters, etc. 20 miles isn't a lot but if you're topping up every-time you use the car anyways it adds up or at the least means you only need to use the fast charger once every few months at the most.

mmaurizi··on U.S. annual inflation rate drops to 8.5%
What about where you park at work? Or when grocery shopping? There are more options for 240v "slow" chargers than you'd think.
mmaurizi··on Ask HN: What's the next big thing that few people are talking about?
I've been thinking about this for a bit (I happen to live in Philly) & I think the easier answer for cities is instead of focusing on charging "at home" parked on the street, to instead go all-in on destination charging (charging at work, at the grocery store, etc).

Adding charging to a garage or parking lot is easier than on the street, and you don't have to worry about not being able to access "your" spot.

mmaurizi··on US regulators will certify first small nuclear reactor design
Being able to shut down existing gas power plants should free up a lot of gas for home heating.
