Notices by Forth Computer (pythonlinks@mastodon.social)

I am dropping the idea of a LISP soft core. I am focussing on tiny #Forth interpreters on #RISCV. The problem with LISP is that it is not very readable, say compared to Python, and mapping car/crd to vectors is memory inefficient. And not that much demand.

#Forth has a lot to offer the soft core community.

@amszmidt

I could not download the Henry Barker 1977 Garbage Collection paper.

Real time #garbage #collection of the LISP machines was a killer app feature, now mostly disappeared commercially.

Can you recommend a good link to read more.
@amszmidt

Can you tell me more about the A and M memories of the original LISP machines? How are they used.

On a modern FPGA, pico-ice board you can get > 1 Mbit on board memory for $35.

@amszmidt

Since we are reaching the end of Moore's law, there is now an opportunity for language specific processors. Already there are soft core #Lisp, #Pascal, and #Forth processors.

The MIT #CADR Machine is most interesting.

@amszmidt
It will take a couple of readings to really understand it.

Why do you want to build this?

@amszmidt
Here is a good description of the cpu architecture.
https://metebalci.com/blog/cadr-lisp-machine-and-cadr-processor/#system-overview

32 bit code but 42 bit microcode. Brilliant Allows for VLIW parallel microcode.

Thsoe guys were very smart.

@amszmidt This sounds very interesting.

My expertise is languages on stack machines. One of the lisp patents included garbage collection in hardware.

I am now searching for articles on the cadr architecture.

Can the brazillian supreme court also shut down twitter in the US please?

Boeing Joke 1/2

A group of Boeing employees are sitting on a plane getting ready for takeoff.
The pilot comes on over the intercom and says "Folks, we're pleased to have you flying with us on our brand new 737, fresh from our good friends at Boeing!"

Immediately, the Boeing employees all scramble to get out of their seats and off the plane as quickly as possible. It's utter pandemonium in the aisles as everyone starts to panic.

@Gargron I asked my Japanese girlfriend what she thought about the stuffed toy: "It would not sell. It is not cute enough, and it is way too big."

I also expected her to say it is way too big. Space is so scarce in Japan. It is mostly mountains.

yes your girlfriend is cute, but the Japanese are the world experts on making cute stuffed animals.

Is it mostly men on Mastodon in Japan?

I do want you to make money.

@dansup Whether or not there is an actualy invisible string, this is a useful concept. Clearly when the string is cut, it is an emotional injury.

I do not have any bee keeper friends either.
I chose bee keepers as an example of a social group that might love to get together and talk about what their issues are. I think they are interested in urban beekeeping, colony die off and other issues.

So #beekeepers, what would you like to get together and discuss at the next #fediforum?
#bees #bee

( A search for #bee, gives #beer as the second option0

I would love to see another fediforum focussed on end users, rather than technology.

beekeepers
climate activists
Embedded developers.
mountain climbers
etc.

Where each group of people can get together to chat with others of their kind.

Maybe it needs to just be lots of small FediForums organised annually.

Thank you @fediforum for the awesome work that you do.

@fediforum@a.gup.pe

I think that I am not going to attend this week's #FediForum

The original #Fediforum was awesome, but this one looks like it is too focussed on the technologies, and not enough on the end users.

I may still change my mind.
@fediforum

@fediversereport @tvler
I think the best bet is to use #GoToSocial. It should run on a $5.00/month server. My understand is that it is a mature server, and an immature end user application.

I plan on using it, as soon as i have more time.
