[!Cheyenne] Discussions about the Cheyenne Web Server

however, still not working from host.. prob a windows 7 hostname 
thing.
Graham

sure .. a virtual cpu

Terry, try to debug from the rebol console if possible
Graham: what's stopping me to work on such clone project is just 
the business model, hard to earn money from that...
Graham

[8392x2]
sure .. no $ in languages .. Carl has proved that
But it's the long term security of having your own custom environment 
I guess
Dockimbel

derivated products like an IDE could be sold, but it will be hard 
to compete with zillions of other programming languages anyway...
Graham

[8395]
or we could start a bounty for rebol on the JVM :)
Terry

Doc, it's the same prob.. disconnecting at the client .. Cheyenne 
isn't even aware of the disconnection.

Graham, without money, it's just not worth it, you need a lot of 
libraries to make a programming language useful, no way one man only 
can build all the required ones...but if it can generate enough incomes, 
you can pay some developers for that.
Terry: when he issue is either related to the brower or the OS
*then

so it connects, C (short for Cheyenne.. don't know why I didn't think 
of THAT before) prints to the console "connected" .. client disconnects 
and no response from C
Graham

But if you run on the JVM or .net, then won't you have access to 
the libraries then?
Dockimbel

Terry: enable verbose mode in C starting it with -vvvvv to see if 
C see the request
Graham: sure, but either you build an abstraction layer other each 
java lib (using a scheme or a dialect), or you'll just use these 
libs with the java syntax, so better use java or scala directly.
Terry

[8404]
oops my bad, C does notice the disconnect.. the function was empty 
:(
Dockimbel

Graham: without a tight and higher level integration of lower level 
libs, the benefits of a higher language like REBOL will be reduced 
greatly while you'll pay the performance penality.
Terry

The world has enough languages.
Graham

[8407]
So, why do they have languages such as JRuby which in some instances 
can be faster than C Ruby?
Dockimbel
9-Jul-2010
[8408]
I guess it's edge cases, not performances from usual cases (got any 
URL for those benchmarks?)

Same function, different syntax. Performance is hardly an issue anymore 
unless you're gaming or modelling
Dockimbel

Graham: thanks, interesting reading :-)
Terry: interpreted (REBOL) vs compiled (java) language will still 
have a huge performance gap
Terry

[8413]
I have a PHP library that I've been using personally for 5 or 6 years 
now. I'm sure it's of value to someone, but I just can't be bothered 
to market it to the 500  interested individuals
Dockimbel

Graham: my performance mention was for REBOL vs java, not cREBOL 
vs jREBOL
Terry
9-Jul-2010
[8415]
Yeah Doc, but who cares.. what's 2 ms these days?  I/O is the bottleneck.
Dockimbel
9-Jul-2010
[8416]
still, I believe that it would be very hard (if even possible) to 
make a jREBOL with performances matching the C version.
Graham

[8417]
the time gained is in writing .. not execution :)
Terry

I would (and do) focus on the future.. HTML5, websockets.. less on 
the tools, more on the results.
Develop mobile apps rather than low level languages.. the market 
is just too small for the latter.
Graham

And Moore's law solves the speed problem
Terry

Lik e Cocoa.. I've tried looking at that noise a few times now.. 
syntax boggles my mind.. but much of it (iphone apps etc).can be 
done with JS and HTML5..

I think Google use Java to write their JS/HTML
Dockimbel
9-Jul-2010
[8424]
Sorry, but Moore's law doesn't allow REBOL to be used as a generic 
programming language, due to poor performances compared to compiled 
ones (like C or java). You can't even write a decent compression 
lib in REBOL (would be too slow).
Terry
9-Jul-2010
[8425]
which is why rebol is dying.. it's a dinosaur.. 10 years ago it was 
hot, but the ball was dropped, and ruby took it's place.  Stupid 
license / closed source killed it.

The only thing is for a few folk here who prefer to use it for low 
end development / back office.
Dockimbel

[8426x2]
Google use their GWT library.
*uses
Graham
9-Jul-2010
[8428]
So, just call a compression library from the jvm
Dockimbel
9-Jul-2010
[8429]
write in java and compiles to JS/HTML for client side
Graham
9-Jul-2010
[8430]
that's what I said !
Dockimbel

Graham: that was just an example of forbidden usage to *REBOL (as 
long as it is interpreted), performance is still relevant despite 
of current CPU speed.
Maxim

yes especially on web servers.... the number of users of a site can 
quickly slam moore`s law.
Graham
9-Jul-2010
[8433]
Sure .. I understand that for interpreted languages, there are also 
performance downsides .. but the gain is in the time to deliver product
Maxim
9-Jul-2010
[8434]
exactly.
Graham
9-Jul-2010
[8435x2]
That's why people use interpreted languages/scripting languages .. 
 to speed up the development cycle not for writing time critical 
apps
If I write a WP ... it's not computationally expensive ... vs a statistical 
package
