Thanks! That is the right repo. If you want to use it, I hold the copyright and we could relicense it.

"My kingdom for a voice" [1] or maybe "My kingdom for a horse" [2] we did post an item about it on the BRL-CAD mailing list. The Common Lisp community didn't really notice Tovero 2.0 for Common Lisp either.

I was actually thinking about trying a Common Lisp wrapper of BRL-CAD, or maybe doing a native CL port.

[1] REM, Document, "King of Birds", 1987 (Anybody know a good marketer?)

[2] Shakespeare, Richard III, Act 5 Scene 4 (a Tovero is a type of horse)

Because it is more interesting than the use of ML in Bitcoin trading, for example, thanks for sharing it. ;)

I don't know if you are still here answering questions, but I was wondering "What if we sent a musical signal (digital or analog) through the MC14500B (silicon junction or vacuum)?" Could it be used, say, in a programmable guitar effects pedal?

There's a flip side to reconsidering aviation--the choices we make as consumers. Since leaving the aircraft manufacturing industry over 20 years ago, I have flown on 3 flights at approximately 5000 miles total, all 3 of which I wish I could have avoided. I'm not saying everyone could live this way, or that I'm particularly environmentally responsible in general, but it is possible. My life during those 20 years was rewarding and interesting, for the record.

The pandemic was terrible for the most part, but it did give us an opportunity to rethink how we live and work, including how to lessen future pandemics and enviromental degradation with our choices on transportation.

Our company wrote C++ and Ruby wrappers around BRL-CAD a number of years ago for scripted CAD, here is the tutorial for the radio example:

https://mirrors.sarata.com/non-gnu/tovero/Tovero_tutorial.pd...

We used it for a few small projects. BRL-CAD also has Tcl scripting.

We've currently switched to pure Common Lisp and F-rep modeling for scripted CAD. This is the old CL one (again wrapped C++) we are porting:

etc.

You can remove the paper filter and clean up liquid spills--plumbing overflows, accidents in the kitchen, etc.

From the guide:

> The original, and most iconic manufacturer of wet-dry vacuums, the privately held Shop-Vac Company, imploded and went out of business.

A disappointing sign of the times, but luckily (so far) I've been able to find 3rd party replacement bags and supplies for my 3 Shop-Vacs online.

What a great idea! There was also a sequel:

I'll look into doing these, I also know a librarian who might be interested.

I really can't believe Disney or Pixar, or some studio didn't make "The Flying Girl" into a movie. It really was bold and quite moving to see Baum (writing nom de plum as Edith Van Dyne) make the female character the hero, back in 1911.

My wife is an admin on the PG project. She puts in a lot of effort to keep the site secure. I think they welcome efforts like yours, and reuse is part of why they exist! They also research the copyrights, to make sure they are clear to share.

I use Project Gutenberg a lot personally, and in fact I'm using one of their books as a study for my upcoming startup:

One thing I really like about the PG site is that a few years ago they removed most of the JavaScript, which IMO makes it more usable. I haven't looked at Standard Ebooks yet, but I look forward to. Thanks!

One book I'd like to see on Standard Ebooks is "The Flying Girl", which my wife and I just read and loved. It's by L. Frank Baum (The Wizard of Oz), and is about a flying startup in 1911, which I previously posted on HN:

I couldn't read the article either because of the paywall. As an anecdote, I remember when we lived in Colorado, they wouldn't allow collection of runoff from the roof of our house into barrels, e.g. for gardening, because that water was already accounted for downstream.

Now in North Carolina, we can't shed rainwater enough, fast enough, and our gutters overflow all the time. We spent $4000 on drains to prevent the lawn from being swampy. There doesn't seem to be a happy medium. :)

I found this interesting book on Project Gutenberg, by L. Frank Baum of "The Wizard of Oz" fame, about a girl and her brother doing an aircraft startup around 1911:

I didn't realize they used the term "angel investor" even back then!

Read and enjoy!
