Compiler business prospects

Compiler business prospects

[Georg Bauhaus]

AP reports:
"White House officials say President Barack Obama will call on Congress on
Tuesday to pass legislation that, among other measures, would eliminate tax
rates on capital gains for investments in small businesses and extend for a
year the ability of all businesses to immediately deduct all of the costs of
equipment and software purchases."

Does this mean that more compilers will be sold during the coming months?

Re: Compiler business prospects

[Alan Jump]

Only if Congress passes it. A President can "call for" anything under the sun, but if Congress doesn't pass a bill to bring that into reality, it's just a call.

Re: Compiler business prospects

[anon]

You every head of ready-made projects

The changes would only help the general population software aka ready to 
use, such as: accounting packages or other business related packages or 
educational learning software.

Microsoft will get a boost, but for Ada or Linux nothing. Because Linux is 
still free for the most part. And Ada software, is too specific or 
design for a single user application.

Are you assuming one cannot make a single-user application in Ada ?

I can call for compilers from the vasty deep.
But will they come when I call?

As a newbie who has started to appreciate Ada (after an initial
painful learning phase) I'd say that Ada doesn't need another compiler
but rather an *affordable* cross-platform GUI toolkit that can be used
for the development of commercial software.

By affordable I mean 100$ to 300$. I would love to use Ada for larger
standalone GUI applications but the main choices QtAda and GtkAda are
simply out of question for a hobby shareware developer like me. :(

Someones don't agree, and I understand the reasons why… but still two  
things: there is no GUI toolkit which could please everyone (just think  
about portability issues: GDI/Windows, GTK/Ubuntu, Cocoa/Mac, Qt/BSD, and  
some others), and there already is a handy to use and portable GUI  
interface, which is a web page in a web browser (all major platform comes  
with at least a modern browser). Unless you need real‑time graphics or  
real‑time audio, a web page is a good material for a GUI (you will just  
need a socket binding and some serialization to talk with the UI).

If you want to program on Windows only, you have a nice toolkit here
http://sourceforge.net/projects/gnavi/
for 0$. You can make standalone executables (0 DLL!).
GWindows is used in freeware and business applications, so why not
shareware as well ?

I don't follow; both of those are available in free versions, and can be
used for commercial software.

If you are asking for _support_, rather than just for the source code,
that is a different matter; support is expensive, and rightly so.

If you are asking for non-open-source commercial software, that is also
a different matter.

Can you be more precise about what your problem is?

What sort of software are you hoping to make money from, and why are
unable to use QtAda or GtkAda for that?

At least about QtAda, as far as I know, it's OK for non‑open source.

Sure, but I'm not sure if it's wise, because presumably this has been
discussed already in the past. Look, I have nothing against the GPL
and am even planning to release some smaller projects under the GPL,
but the fact of the matter is that you *cannot* successfully sell
shareware or run a small business under the GPL because someone will
grab the source code and give his version away for free. That's just a
fact.

BTW, there is no real problem for me because I'm already using Racket
successfully for my GUIs. I was just a bit disappointed that there
seems to be no way to use Ada for that. Languages like the following
ones offer free (as in beer) LGPL bindings to GUI toolkits: C++, tcsl,
Perl, Ruby, Racket, FreePascal, ... just to name a few. For successful
shareware business the key is to provide executables for each major
platform that run immediately out of the box with a native and well-
crafted GUI. Toolkits like Qt make that possible but unfortunately Ada
is the only language I've seen so far where you have to pay for
bindings that allow non-GPL distributions.

Yes, but how much is the GMPL license? I suppose the problem is that
QtAda must be based on the commercial version of Qt, because otherwise
you wouldn't be allowed to statically link to the Qt libraries, and of
course I understand when people want a return for their investment.

You *can* sell GPL software and make a profit. That's just a fact.

AFAIU, Qt has been licensed under LGPL since 2009.

I really didn't want to get into this discussion but I have to reply
to this, because your claim is completely misleading. The talk you
link to is about AdaCore. Sure you can make money with business-to-
business software, especially when it involves very special know-how,
but you do *not* make the money by selling the software. You are paid
for the consulting, product service, and maintenance and *not* for the
software.

I'm talking about making moderate amounts of money with non-business-
to-business, generic end-consumer software - where an executable is
deployed to Joe, the user, from a box on a shelf or via download and
payment by a payment service provider (Paypal, Kagi, etc.). This kind
of software does not require any consulting or services, because it
works out-of-the-box and does not require any skills to operate. For
example, I'm currently working on a word processing application with
unique features for creative writers such as style checking, "dark
room" minimal user interface, automatic backup and versioning,
automatic project management, extremely fast notetaking and search
functions, etc. The only way you could make money with that under GPL
was with a ridiculously large user base (>1 million, which means a few
people might pay for charity) or, say,  by convincing the US
government to buy 10000 copies+5 year maintenance contract. <-- Joke

Anyway,  I welcome it when other people make money with GPL software
but in many of not most cases, and certainly in mine, this is an
utterly unrealistic perspective.

> AFAIU, Qt has been licensed under LGPL since 2009.

LGPL does not allow static linking with the executable. I was assuming
that QtAda statically links with the Qt libraries, and anyway GMPL/
=LGPL, both of which seems to imply that the GMPL version of QtAda
must be based on the commercial version of Qt.

The page confirms what I said. All programs on this web page are
business-to-business solutions -- without a single exception!

Anyway, I really didn't want to get into this topic and want to
apologize to other readers of this group. I can and will still use Ada
for backends and time critical code.

You could buy Janus/Ada Personal edition with Claw from
RR Software for $295. (http://www.rrsoftware.com/)

It is only for Windows, but shouldn't matter that much since Linux
people don't pay for software anyway and Apple wants everything on OS X
to be coded in Objective-C. ;)

As a bonus, you can make your code open, since not that many has
Janus/Ada and CLAW and those who have most likely are not interested
in forking your project and making money for themselves.

Re: Compiler business prospects

[anon]

What I was getting to with the single user concept is. Where are the 
businness or general public application written in Ada that the end 
user can buy at their local online software store. 

Also:

Programmers do not want to spend their life re-writing code written in 
Ada. That is, every new language release requires 80% to 95% of the Ada 
code to be rewritten. Even the yearly release of Adacore's GNAT can have 
so many updates that it can cause a complete rewrite of an application 
even between language releases.

And Ada is still concurrent but the programmer of today require 
multiple-thread and multiple cpu languages. Ada 2012 has some multiple-cpu 
controls but those type of features are still very limited. In truth, Ada 95 
should of had been the first true multiple-thread and multiple cpu language.
And until these two systems are fully functional and I would say even 
going beyond all other languages Ada programming will stay crippled to a 
limited number of concurrent applications.

Then you have features that are included in other languages, but either 
not available or not maintain in Ada. Such as links for OS graphics and 
direct hardware devices such as USB ports. Yes, there are binding for 
SDL and openGL but are those current.  And still most programmers would 
prefer Windows DirectX graphics, or Apple's graphics.

As for Ada, a plus would be a common graphics package that the programmer
could use to create an application on one system and then just compile 
for another system without modify the code. Yet, today no package exist!

So, without these and other features added to Ada, no governmental tax or 
altered law will increase Ada compiler being sold.

Are you talking about the Ada which is the topic of this Usenet ?

On the contrary, all languages release are done with backward  
compatibility in mind (Randy often referred to this requirement here at  
comp.lang.ada). The Reference Manual always points potential  
incompatibilities, and these are not legions.

Again some incredible junk from anon. I rehosted Ada 83 embedded
software (several hundred thousand LoC) to different hardware with Ada
95, then moved on to Ada 2005, without much ado.

Seems like this guy is the worst programmer ever on earth.

That's what the music industry said about CDs, until Apple proved them
wrong with iTunes.

If you are selling a useful product (for instance an Android app), the
majority of people will be willing to pay something for it, rather than
use an illegal version. Hmm, I guess "illegal" is the wrong word here;
if you are using GPL, the free version will not be illegal.

You have to sell it at a price they are willing to pay. You may have to
offer support, or upgrades, in addition. You have to advertise to get
people's attention.

The people offering a free product will not be able to offer either
support or upgrades, nor will they be able to afford advertising.

I have no idea what the license is for most of the apps I've installed
on my Android; even if they are GPL, I can't be bothered to get the
source and compile it. I'd far rather pay someone else to do that.

Your issue is free as in freedom, not free as in beer; you do not pay
for the GUI bindings. The issue is what freedoms you have regarding
distribution when you use them.

The "problem" is that people need to eat, so they need to get paid, same
as you. If you are making money by using other people's work, it is only
reasonable that they get a cut. Maintaining QtAda is work!

You left out the Android market. Which is Linux way down underneath, but
most people don't care about that.

I tried to import the Android GUI into Ada, but GnatJVM isn't quite up
to that, and AdaCore doesn't see enough market to support fixing it.

So you are stuck with the free Java GUI.

That's a nice angle :). I can just see an add for CLAW:

    Keep your software safe! Use our totally obscure system to compile
    it!

No. The FUD is in thinking *a priori* that this business model is
"impossible" and presenting that as a "fact".  What I said was not
FUD, it was perfectly correct and it is a proven fact that one can
sell libre software and make a living, like AdaCore has proven for
decades.  However this is not true in all cases as Robert Dewar
himself admitted during his keynote speech at FOSDEM this Saturday.
One case where this business model is not sustainable is when the
product is expensive to make but must be sold at a low price; this is
true of movies and video games among other things.

It was not obvious from the OP that he was envisioning selling cheap
software for consumers.  The fact that he wants to run a small company
does not imply that the products inexpensive; I myself have worked and
still work in a small company selling expensive products and services
to big corporate customers.  I believe this is in fact the case of
many regulars of comp.lang.ada.

More generally, I personally believe that small companies cannot
compete by selling cheap products in the mass market and that this
applies not only to software but to pretty much everything; this is
because the key to succeeding in the mass market is to control
distribution channels (i.e. retail stores).  This is much more work
than a small company can handle and a one-person company wants to
spend their time developing, not marketing.  A small company that goes
to the consumer market usually ends up being controlled (and
pressured) by their distributors.  It is easy to see this in bicycle
shops and their suppliers: the small ones thrive and survive only
because they sell expensive high-end products, expert advice and
premium customer support, thereby avoiding the mass market.  Mind you,
these are not "facts" but only my perception.

Correct but irrelevant.  If you want to program using QtAda, you're
going to have to link your program against both QtAda and the
underlying Qt (and possibly other libraries too), therefore you must
consider how the licenses of both Qt and QtAda (and the other
libraries, if any) affect your program.  Qt is under LGPL at no cost.
QtAda uses the classical dual-licensing scheme: GPL at no cost, GMGPL
at extra cost.

One talks about an absolute appreciation, the other about a practical  
appreciation.

It just happens that although possible, this is hardly done and unlikely  
to work for most. People arguing that's impossible are wrong about the  
whole, true, while people arguing that's possible, are wrong about  
effectiveness too, when they forget to provide any kind of evaluation  
(like providing probability of success, which is known to be very‑very low  
with that model).

It happens too, most people complaining about that fact, will fall in the  
common case where it's not possible. If that was more likely possible,  
believe people who mean they would be the first glad to go for the  
adventure (I'm of these ones too :-P ).

May be you are both right and both wrong and precision was lacking (Ada  
designers failing to provide relevant specifications, what a shame :-(    
... just teasing :-P ).

That's a clever analysis.

Will keep it as a note somewhere.
