One doesn't need to use the menus, one can use the keyboard commands. The UI provides several ways to interact: key commands, interactive command line and menus.

Genera comes with a Scribe-based markup language and formatter.

I made this video years ago on Lisp Machine. The new emulator for the Mac & Linux is many times faster and runs silent on something like a MacBook... Thus it's ,uch more convenient to use that for a demo, unless the software does not run there. The emulator has its own native code format and, for example, lacks emulation of the console hardware (graphics hardware).

You mean, the humanity has not gone too far away when it comes to computer-human interaction back from those days? :-). Just kidding; that sounds like they were quite modern back in 80's. I saw the other video on YT about their graphics software and hardware. While it looks relatively simple compared to modern image editors, modellers, fx and animation packages, it still feels like they had all the right ideas. What do you think put them out of the business? Just the economy or some other more technical reason?

> The new emulator for the Mac & Linux is many times faster and runs silent on something like a MacBook.

Yeah I saw another video, and saw "machdd" or something similar on the modeline somewhere, so I assumed you made it on a mac.

> lacks emulation of the console hardware (graphics hardware)

That explains why all the demos are black and white.

I don't have so much time to install and configure virtual machines and programs, but one beautiful day I'll try it, just for the curiosity; I have seen the repo on GH.

The main reason was the end of the cold war and the end of the high-tech war. Means there were too few commercial customers. Where they had commercial customers (like the Graphics & Animation business), there was a disruption by other technology, like SGIs (RISC CPUs with powerful graphics accelerators) and also Windows NT. The graphics software was sold to Nichimen and ported to SGIs and Windows NT.

> That explains why all the demos are black and white.

All the Symbolics early consoles were black & white, so all the software was using b&w. Typically the machines had an additional color screen, then with an additional color graphics board. All driven by Lisp. But the megapixel color screens and graphics boards were very expensive. They also might have been too slow to use as an interactive console screen.

The emulator support graphics. It's X11 and one can use color graphics, but the graphics & animation software hasn't been ported to X11 AFAIK. It's just that the normal tools don't use color in their UI, though there were applications which used color.

> I have seen the repo on GH.

Don't expect too much. That's an old, unsupported emulator, which has a bunch of technical problems.

And now even SGI is out of business. It is a little bit unfortunate, but I think there is a history lesson to learn. Symbolics, SGI, Sun, Xerox, IBM, AT&T, they are all gone from the software business, more or less. I mean IBM, AT&T and Xerox are alive, but they are just a shadow of former self they once were, at least on the software front. Seems like all companies that target high-level industry with big profits, and ignores the consumer market are fading away.

Compare that to Microft which exploded in market share after their Dos/Windows and Intel which exploded after their 8086/8088. It just shows how important it is to put the technology out to consumers. Not because mass consumers will create so much value, they will that too of course, but foremost they will learn how to use the technology and once they come to businesses and have to solve problems, they will use it. I think that is a problem Symbolics faced. They run on dedicated hardware that probably was a multum in price and was used for specialized problems, while worse technology was cheaper and more accessible. People used what was accessible and when a generation grew up and went to work of course it is cheaper to let them use what they have learned then to buy specialized hardware and train them in specialized language. I think same thing happened to SGI when big graphics software names released their software for Windows. I think it is a circle, or a rolling stone. It is important to put the technology and knowledge out in the hands of people.

It is a bit sad that LW and Franz are keeping their software behind the locked gates instead of letting them out in the free. I bet some middle-tier manager is sitting at the Boeing as of this writing and trying to figure out how to save $$$ by cutting out that crazy expensive expert-knowledge Lisp thing out of their software stack, just to save some $$$ and get promotion or a bigger bonus.

If LW and Franz are going to survive and not go same way as Symbolics, Sun & Co, they should probably rethink their strategy of licensing their stuff free for GPL/non-commercial use, similar as Qt and some other companies do. Perhaps SBCL is good enough, but Lisp community needs more and better tools. In expert hands Emacs is s superb tool, but it is not the average mass tool.

It is a bit shame. I think Lisp is such a great tool for software engineering and applications development, but it is so underused because the knowledge pool is so small and the best tools are locked away behind the pricey tag seems like. If/when those two guys are gone, LW and Franz, Lisp will be seen even more as an academic exercise rather than a useful practical tool.

I don't know, perhaps I am wrong, just thinking loud.

I'd think there were like 30 commercial implementations of Common Lisp. LispWorks and Franz are still alive. None of the others are. Personally I'm happy that they exist and fear what you propose would kill them very quick. There are also a few inhouse implementations "alive".

> and the best tools are locked away behind the pricey tag

If there would be a business opportunity someone else can pick it up.

LispWorks reused bits and pieces of CMUCL. But the stuff they've added provided real value: robust ports to different platforms, an extensive implementation and a portable GUI layer.

If someone sees a business, they could easily layer something on top of SBCL or provided other improvements.

Scieneer tried that with CMUCL by adding concurrent threading for multi-core machines.

Clozure CL was alive while there was the expertise of the old hackers. Once they were gone it was difficult to keep it ported to new platforms and to fix hairy bugs. They tried to have a business model with an open sourced variant of Macintosh Common Lisp.

We'll see dev tools financed by big companies like Microsoft, Oracle, Apple, Google, ...

Then there are a bunch of companies trying to provide tools (Intellij, ...) or alternative languages (Scala, ...).

The specialized niche languages tend to have capable implementations with large price tags. See for example the commercial Smalltalk implementations of Cincom or SICStus Prolog ( https://sicstus.sics.se/order4.html ).

Other financing models tend to be fragile... or depend on other sources... like research/academic funding.

[amno]

> LispWorks and Franz are still alive.

Yes, but what makes us believe they won't go the same faith as all the others?

> fear what you propose would kill them very quick

Why? Is their technology that bad? I don't think so. I think they need to let people use their stuff, show to the masses the good things about Lisp and their tools and let the masses learn how to use those tools.

> If someone sees a business, they could easily layer something on top of SBCL or provided other improvements.

It is not just. Layering something on top is a lot of work :). It is software, everything is possible, but who has the manpower and time? However people do layer stuff on top. We do see people making cool and interesting stuff, but it is relatively few enlightened persons. We don't see a mass movement; perhaps masses need to see a "killer app" or something, like when JavaScript got Chrome and went from verbotten on every computer to No. 1 language (more or less)?

I think the business is made by giving the technology to people, and letting them use it. Once it is in use by individuals and people realize the power of their tools, I believe it will see more use in businesses too. As I said; I think it is a "vicious circle" as they say here in Sweden.

> Once they were gone it was difficult to keep it ported to new platforms and to fix hairy bugs.

Yes, that is a normal thing. Once the experts are gone, the platform is dead. To survive, a platform needs to attract new people and bring them up to expertise level. But every platform also has to adapt and as well to be well documented. I wish to make an extension for sbcl, I don't see any writing anywhere on how to proceed, so I have to look through the source code. It is not impossible, but is more tedious than it perhaps should be. The best thing with Emacs is actually the documentation, and the openness. I think. I don't know for sure, but it seems so.

> The specialized niche languages tend to have capable implementations with large price tags. See for example the commercial Smalltalk implementations of Cincom or SICStus Prolog

Anyone still using Smalltalk? :) Yes, of course, I agree. What you describe is how the business was done, but I don't think the history speaks in that favor. I don't know, all this are just my speculations of course, but I think that is an obsolete view on the business. It seems that all those specialized companies that target big biz are sooner or later out of that biz. What would it mean for Franz to loose Boeing? Probably quite a lot. I don't know. I am not sure Oracle is doing that great as they did in the past either. There is a lot of inertia too; big customers can't easily switch. I mean, Cobol is still there, but it does not mean Cobol as a platform is doing well.

> Other financing models tend to be fragile... or depend on other sources

I didn't mean they should switch to some other form of making business and financing. I just mean they should let their tools go free for the masses, for people making open source code for non-commercial use. For businesses they should still sell and charge of course. I don't know, perhaps I am wrong; but which hobbyist like me will pay LW 400€ for the basic license? Or whatever is the price now. They wont make money out of hobbyists, students, indie devs and alike, so they can as well let those people use the thing for free for non-commercial and open source use like other companies do. Perhaps if they have good tooling, gui builders and so on, people will use it to create some interesting stuff, more people would learn how to use their software, and that I mean would play in their favor in the long run.

By the way, to mention is that Microsoft, Oracle, Apple, Google gives away their tooling basically for free, because they have realized that they want people to learn and use their tools. I don't know, perhaps there is not money in traditional tooling like GUI builders at all in the world of web technologies.

Don't get me wrong, I don't wish them anything bad, but I think that the Lisp community is so small and fragile, and it would perhaps help with the better tools. I think is a shame because it is a nice language for rapid prototyping and development with lots of potential that the humanity perhaps is slowly loosing; but now I am perhaps bit too dramatic and cheesy :).

[lispm]

> Yes, but what makes us believe they won't go the same faith as all the others?

Switching to an open source model would mean that only 1% of the users would pay anything. To make that viable you need a good business model for a much larger or a different market. The business model is vastly different with a vastly different product.

Just open sourcing the thing is an easy way to kill an existing company, which now has a small, but paying customer base.

[p_l]

The issue with console hardware is that some applications use old code paths that directly call into the most basic framebuffer Symbolics Lisp Machines had, and that is not supported on X11 - thus said software doesn't work neither on OpenGenera, nor on UX400, UX1200, and NXP1000 physical lisp machines (all of which lack console hardware and use X11.

The only exception is AFAIK MacIvory, which has special subsystem that emulates console hardware on top of Macintosh toolbox calls done over Sun RPC.

[_19qg]

The MacIvory has the option to use a NuBUS color graphics card directly from Lisp: a NuVista board.

[p_l]

Yes, but that's used by COLOR package, whose interfaces are IIRC mostly available on X11 client as well (minus acceleration).

The TV package in the full was redirected only on MacIvory, not on Unix-based setups, notes from OpenGenera suggest that the plan was to fix the application packages to use new interfaces instead.
