namespaces

[SJain]

Are there any namespaces in 32 bit picolisp? How are local variables defined? 
As transient symbols?

I am newbie in picolisp.

math.l library in picoLisp

[SJain]

I use fixed point math quite a bit and have the following question about the 
default math.l library of picoLisp:

The trigonometric function Sin is derived in math.l from the shared library and 
function specification ext:Sin. Where can I find this shared library 'ext'?

Would appreciate if some one could answer this.

Re: math.l library in picoLisp

[SJain]

Thanks so much for the clarifications on namespaces and shared library 'ext' on 
pil32.

Is it customary to end with a thank you on this mailing list? If not, then I 
will omit it in future to avoid cluttering the mail.

graphics in linux text console (frame buffer)

[SJain]

I have a weird question:
Is it feasible/possible to produce an x-y plot (called a graph in science) in 
linux framebuffer text console by programming in picoLisp? The application is 
to do data acquisition (daq) in text console and have bare bones plot of data 
while measurement is going on. Of course a publication quality plot would 
require the GUI and a plotting tool.
I would appreciate any comments on this.

strong language for blockchain

[SJain]

   There was a mail regarding picoLisp for blockchain. I am No expert in 
software, but I would have thought a compiled language with encryption, with 
full source code available, would be a more secure application than a 
interpreted language, requiring source code in readable and writable text file, 
such as picoLisp, despite all it's charm.
   I would appreciate any thoughts on this.

strong language for blockchain

[SJain]

Again first let me again say I am not a software but an electrical engineer 
with an interest in good software. It occurs to me that adding encryption to 
picolisp might be useful for safety if it allows running encrypted source code 
files. I know of a Forth-like concatenative language called 8th (search 
8th-dev) which has such encryption built-in, but it is not open-source but is a 
paid software.
From another practical point of view, instead of encryption even bytecode 
compilation would be satisfactory, not for reasons of speed but for security 
that the application code file cannot be tampered with as easily as with a text 
code file.
For example in a research lab, a scientist could pass off bytecode file to 
subordinates without being worried about inadvertent or intentional alteration 
in it.
I would appreciate any thoughts on this.

BR,
SJain

picoLisp for blockchain

[SJain]

Many thanks to Beneroth for clearing the air on utility of encryption. It 
restores my faith in basic text source code.

As an engineer and practical scientist, concerned not with number crunching 
speed but with teaching elegant and useful programming language such as Lisp to 
students and subordinates, I still would be happier with a 'somewhat' greater 
degree of security from tampering, as afforded for example by bytecode files, 
in particular usecases such as automatic test equipment setup for reliability 
of measured data. Can that be achieved in any way within picoLisp?

mail landing in spam folder

[SJain]

A lot of mail from this mailing-list, but not all, is landing up in my spam 
(Bulk mail) folder, and I can't do anything about it. This is just for your 
information.

pointer to a symbol: how to know it

[SJain]

I shall be grateful if someone could explain how to get the 'value' of a 
pointer to a symbol. It is said in the documentation that evaluation of, for 
example, the function * returns its address or the pointer to it. Evaluation of 
a symbol however returns it's value. How to get the pointer to the symbol? This 
is just curiosity as Ms Mia's blog says one can know what is stored where in 
memory. Thanks very much,
