Dearn Python Developers,

I must say how thankful I am for Python. It has saved me at work once so
far. I am working on a program to poll data from a server, but I don't have
the actual server. I was fortunate enough to get sample data files from the
server and fairly decent specification. So, I embarked on my mission to
write a mach-server that emulated the real server. I was successful at
writing one in Perl until today when I found out that the data I was sending
to it was not the right data. I was having a difficult time parsing the data
in Perl (not too familiar with the regular expressions & perl syntax seems
to be a bit buggy to me).

Well, this weekend I happened to decide to learn Python because I know C++,
Java, Visual Basic and a few other minor languages (or so called languages
like HTML & SQL). I needed to know a good scripting language for UNIX
Administration and simple utilities that I like to maintain my computers.
Python looked like an excellent candidate because of it's object oriented
features and it also appeard to be quite simple, which has turned out to be
the case.

This afternoon, at work (in about a 20 minute time period) I rewrote the
mach server that I had originally written in Perl and it works much nicer
and more reliably than the Perl version which I was using before. The server
works quite nicely and was surprisingly written in a few less lines than the
Perl server was written in. I hope that my boss is impressed.

Sincerely,

John Brainard

To impress your boss more, use 'mock' (imitation) instead of 'mach'
(speed number) when you write your report.

I apologise for posting anonymously to this group. I had no idea that
newsfeeds would hide my e-mail address when I posted. I have nothing to hide
from this news group, or any other that I read from and will change my sig
file to include that and my icq number.

As for the misspelling, I am truly embarassed by it. I am normally quite
about checking it.

Welcome to the Python community, John. Yes, Python is a truly
wonderful language for cranking out quick prototypes or test jigs.
I prototyped a complete web-based general ledger system in Python,
figuring I'd downcode it to C for speed later, but so far I haven't needed
to. Python is also just plain fun... Now if I could just get time to port
it to the PalmPilot, I'd never be away from it.

Do a web search for "uclinux". It's a Linux kernel being worked on
at Ryerson University somewhere in Canada. I don't know how stable
or developed it is, but it might run Python.

I'd like to see somebody take the old HP100LX palmtop design, pop out
the ROM, and put in a Python interpreter (and PIM stuff written in
Python) in its place. That would be cool.

Get a Windows CE Palm-sized PC if you want to take Python with you whereever you
go. Python runs stunningly well on my Casio E-100, and has nifty GUI
libraries. It's not polished by any sense of the word but it works, and the
source is a barely changed version of the standard windows Python. This makes
for easy improvement.

see:

It sure is nifty to be coding during my commute :-)

More than a bit offtopic, but you can program in Forth if you use
free Quartus here http://www.interlog.com/~nbridges/quartus.html
After I downloaded a debug ROM image from 3com I was able to run it
on http://xcopilot.cuspy.com/ under Linux very nicely.

Sure, but we've got Pilots, so that's not an open option. Fortunately,
the Pilot has Quartus Forth available for it -- it's not Python, but
honestly, Forth fits the limitations of the device better.

I used Quartus on my Crypto exam to solve a modular equation after I
forgot how to solve modular equations (I had it use brute force).

I'd still like to have Python, but dang, Quartus is good at what it does.
Python and Forth -- for two different reasons, pretty much my favorite
languages.

You know, the first time I saw this it was in ESR's .sig, and I tried to
remember how long the Perl version had been. A few minutes of searching
revealed that it was three lines long -- but also revealed that it was
using bc rather than Perl to do most of the work! I spent about half an
hour searching for the real Perl version, only to find that it was five
lines long.

The Python for this .sig is shorter than the Perl! Cool, eh?

Sounds like a job for Itsy, if Compaq ever decides to release it as a
consumer product.

http://www.research.digital.com/wrl/itsy/

Runs under Linux with GNU tools on the StrongARM SA-1100 with 16MB of
DRAM (expandable), onboard USB, etc.

They're already fooling around Java and Squeak versions.

In fact, it appears generally rather Pythonic in design. :)

I suspect there won't be one running native ... the memory model of the Palm
is sufficiently restrictive that it may be fundamentally incompatible with
the Python memory model. On the other hand, I'd love to be proven wrong.

That said, you can write all the host-side components to your Palm app
in Python:

It doesn't run for me... What's it supposed to do? When I run it, I get:

Traceback (innermost last):

I had a Pilot for a year before I realized that it wasn;t what I needed. It's a
glorified organizer, when what I wanted was a pocket computer. So I shelled out
for the E-100 and I've never looked back. The difference is light years, not
miles.

Wow! I wish I had had my E100 when I was in college. I just realized how
awesome that would have been. :-)

The SECOND time I saw that sig was in ESR's mail. The first was mine. I doubt
ESR copied mine, but who knows? :-)
Actually there IS a 3 line PERL version, but it does use dc for the heavy
lifting. I consider that cheating.

But if the world is a giant computer run by white mice as
Hitchhiker's says, then wouldn't there be time travel? From a
rough memory, the Guide lifted text from a ceral company then
went back in time and sued the company for copyright infringement.

So after The Matrix came out, the mice went back in time and
had (pursuaded, brainwashed, induced, etc.) Douglas Adams to
write the book then got it turned into a movie.

I have a certain amount of leeriness about posting advocacy on unrelated
NGs, so I'll limit myself to saying that the difference is years, not
miles. The two machines work differently: one is a glorified organizer,
the other is a pocket computer. Both of them can fool you into thinking
they're something else, because they're both powerful.

I need a personal organizer.

Oh yeah.

Actually, I sometimes miss my old OmniGo, which was a pocket computer, in
spite of being slower than the Pilot for some tasks. I really needed the
glorified organizer (and had been fooled into thinking that the OmniGo was
one), but the OmniGo had some abilties that the Pilot doesn't.

You mean you wrote it? If so, there seems to have crept into it a bug --
one of the implicit unpackings don't work.

That's what I said -- the first one I found was written in Perl, but used
bc.

I'd generally agree, although I like Forth a lot too.
