I used to work in Manhattan, you 100% don't need a car there. A backpack for your stuff. Subways are a bit faster than walking for short/medium distances, faster if you're going interborough. But cars are so so much slower. Trying to drive in Manhattan traffic is torture. Maybe you need better walking shoes? Manhattan isn't flat but I wouldn't call it super hilly either. It's mostly level grade, and the sidewalks are for the most part well maintained.


Plus one on this. Would be amazing if there was a display mode possible or just a variant with a usb to edp board inside without the android tablet bits / battery (even if it meant losing the wacom digitizer in the process)


There's an entirely web-native replacement for upload/downloading tracks now https://stefano.brilli.me/webminidisc/ It's based off the reverse engineer minidisc python libraries and, imho, is super impressive. The author even figured out how to dump atrac data off any netMD capable deck (not just the MZ-RH1).


Minor note: ATRAC extraction on non-RH1 models and Hi-MD support is only available on the fork at web.minidisc.wiki (Web MiniDisc Pro).


Growing up in the north east, my parents had a solar pool heater (they still do), Heating a pool via thermal collectors meant that we could reasonably use the pool through the end of September / early October some years, and it wouldn't be freezing cold on hot days in June before the water had a chance to warm up naturally.

It also had the side effect of keeping the heat off our roof and would actively pull heat out of the attic. PV panels would have worked with a heat pump but probably would have cost a ton more for the required capacity needed. Not to mention the extra heat on the roof from not having it watercooled.


"PID (Proportional, Integral, Derivative) works by continuously monitoring the boiler’s temperature and making small adjustments to maintain an exact and stable target temperature."

So basically a smart thermostat that accounts for ramp up and cool down times when adjusting the temperatures.


Yes and no. PID loops are linear systems and don't understand ramp-up and ramp-down times. They understand poles and zeros. So normally you would speak of time constants and bandwidths rather than ramp (slew) rates. This is not just semantics, they function differently. However is not unusual to add non-linear constraints on top of of linear control loop so you end up with a hybrid control system.


The Cray-1 had 160 MFLOPS, and a single Pico has about 133 KFLOPS, so 8 of them would be just over 1 megaflop (not accounting for any overhead). So about 1/160th!


That's only part of the story. Cray spent a lot of time architecting an I/O system that could keep the CPU fed. So peak and sustained performance were closer than a lot of systems.


Thanks!



This is a cool laptop but after looking it over I hope ThinkPenguin decides to sell replacement batteries (since they are removable) and perhaps even a higher capacity one that sticks out the back a bit. Also the inclusion of a B key M.2 is great for say, an LTE modem, but the page makes no mention if they wired a SIM card slot up to it. Another thing I wish was an option would be to configure without a wifi module, since not everyone is focused on libre firmware, it'd be nice to throw a generic wifi+bt module in there, rather than have to rely on an external bluetooth dongle. I know I can just swap it out later, but that's sunken cost and e-waste for the built in unit which kind of stinks.

EDIT: I checked around their shop, they do sell replacement batteries for $109, but I still wish they sold an extended cell variant like laptops did 10 years ago.


I just added a base configuration to the cart to see the price, looks like it starts at $799, which is pretty reasonable imho.


I have a soft spot for sun rays. Back in college I had one set up in my dorm room that I grabbed from a surplus supplier that hooked into the school's servers so I didn't have to go all the way to the computer lab to work on my assignments. (I still have my smart card somewhere)

I remember thinking back then (2013) when this tech was getting sunset that we had somehow gone the wrong way, and that thin clients were the future, especially from an efficiency standpoint.

I still believe that, but we're still a ways off from general purpose compute accessed over the internet for the majority of use cases.


See https://taoofmac.com/space/blog/2022/10/23/1700 - the dream lives on, although people still prefer local compute.


> and that thin clients were the future, especially from an efficiency standpoint.

I feel like we keep inventing thin clients and then making them thick; I consider Chromebooks the next step in the cycle.
