i suppose if one is worried about thrashing
one could always hook up an NVME to one's Pi...

Though what has me salivating is

Thanks, Bob.

Yes, 40something-year-old kid!  Sounds as though the pi 4 is more
bedded-in than the 400.  Pity there isn’t a 40-something Pi.

Lots to chew on,
Thanks again,
Mike

Hi, Mike,

>I have several Pi machines kicking around my lab, for various projects. They 
>are simple and super, IMO.

>The Pi 4 B is quite good, I find: 4 cores, two 4K HDMI outputs, WIFi, and 
>more. It comes in several variants of DRAM, but I suggest that you just get 
>the 8GB one, as it gives you some of that inevitably needed elbow room. DRAM 
>is not upgradable - it's soldered onto the motherboard.

>I just looked at the Pi 400, but it only comes with 4GB DRAM, at present. Wait 
>for More DRAM, Igor.

>I think the best deal for a newcomer is the Pi 4 Desktop, which does come in 
>an 8GB version, and it has everything you need except a monitor - it comes 
>with two HMDI cables, mouse, & keyboard. Nicely packaged, well documented, and 
>with enough guts that you can run a [small] web server on it:

https://www.raspberrypi.org/products/raspberry-pi-4-desktop-kit/?resellerType=home

>In Canada, I ordered an 8GB one of these for $238CAD, including all taxes and 
>shipping. It arrived at my door two days later, from these people:

>I think the best thing about the Pi for me is the ease with which anyone can 
>do simple projects involving robotics, computer vision, electronic and device 
>controls, and the like. The book that comes with it is a great introduction 
>for the uninitiated who want to experiment in such areas. Several artists in 
>my community use Pis, as well as arduinos and such.

>Dyalog APL offers free downloads of their APL interpreter for the Pi:

>straightforward, since the Pi runs linux. Ah, this looks like one:

>One of my Pis here has a $50CAD-ish (so-so) camera hooked up to it that I plan 
>to use for some more work on Convolutional Neural Nets (CNNs) [Now rebranded 
>as "deep learning"] in APL. An early paper on the subject is available here, 
>but if you don't have access to ACM publications, let me know:

https://dl.acm.org/doi/10.1145/3315454.3329960

>Here's your homework: get him to try out Mathematica, then write him a 
>one-page Rosetta Stone page of Mathematica ?? J, with a few bits showing where 
>APL and J "just work", without dumb limitations on rank/shape, etc.

>I think the Pi is a great gift to inspire creativity in kids in late 
>elementary school or later, even if they are 40 years old.
