You're still surprised that *YOUR* crap code doesn't return data,
funnier by the minute.

"Here Nikos have some code and a database design that works".

"No I'm doing it my way".

Your one saving grace is that if someone decides to sue you there's not
much evidence. Apart from a few threads that you've started here, of
course.

Yet reading the documentation of fetchone, would have informed you of
the reason and removed the surprise. Reading that documentation would
also have taken a minute at most. Yet instead of reading the
documentation and be informed within five minutes, you chose to waste
your time by repeatly coming here in the hope that someone would
spoon feed you. Even when you should know by now that people here
are getting less and less inclined to do so.

The way you behave looks like you are doing it purposeful in a way that
is least likely to be fruitful.

If one of us were to feel sorry about himself, that would be you because
of suffering of Autism disorder.

You have demonstrated significant difficulties in social interaction and
behavior.

I haven't felt better in years so why should I feel sorry for myself?
Besides humour is a great thing, and with such a wonderful comedian as
yourself to boost my feelings, what more could I ask for?

I don't need help thank you as I've already had it. You on the other
hand are past help.

But let's not waste any more time on this. Please get back to checking
your web site. She might have been hacking again. Or little fingers
from one of my highly paid contractors might have been up to no good.
Oh but I forgot, you've made it hacker proof now. You'll sleep much
better knowing your site is safe. Or is it?

I don't think so. As far as I am concerned the person demonstrating
significant difficulties in social interaction and behaviour is you.

Mark may demonstrate he has difficulties in interacting with people
who demonstrate difficulties in social interaction and behaviour to
a larger degree as usual but I have less problems with his behaviour
than I have with yours.

Many visitors per hour in my website.
They didn't manage to mess with the db again or the variables i'm utilizing.

The hacker maybe a blondie and she cant get a workaround after my changes.

At least lest hope she is a pretty hacker wannabe :-)

let me get this straight

You have no aptitude for programming,
your database skills are non-existent,
you have no clue regarding even basic debugging techniques,
you an an incompetent system administrator,
you cannot even follow basic instructions when you ask for assistance Yet
you feel you can make blond jokes and belittle someone who has
demonstrated the flaws in your set-up multiple times?

I have not laughed so much in years. You really should be on the stage,
there is one leaving in 10 minutes.

I have all of the above characteristics in a small degree.

If the mighty hacker is so good and i'm so bad in programming and
securing my script why cant she break bad again?

And why are you posting under your real name but as "unknown" instead?

Most of the "advice" I've seen posted here has, as far
as I can tell, not intended to be useful but to serve
as a way to telling you are incompetent are in other ways
insulting or useless. I think you are quite right to
ignore it (or tell the poster to get lost.)

Long before you showed up here, I noticed the tendency
to not answer questions directly but to jerk people off
by giving hints or telling them to do something other
than they want to do.

Often that is good because the original request was
for something that the OP really didn't want to do.
But sometimes the OP knows they want to do (but doesn't
want or is unable to clearly explain why) and when
they clearly state that, yes, they do want to do it
their way, their question should be answered in good
faith or, for those who just can't tell how to do
something "wrong", ignored.

Instead the response is typically a lot of hostility
directed at them for not "taking advice". In other
words, the advice here is not free advice, but come
with the price that you are expected to except it
gratefully whether it was what you asked for or not.

I think you are quite right to reject advice that does
not do what you want and ask again for advice that does.

FWIW, I am quite sure there are other readers of this
group who feel the same way, but most people aren't
willing to subject themselves to the bullying that
will be directed at anyone who publicly agrees with you.
It is the same way in real life too as I'm sure
you know.

Just wanted to let you know that not everybody here
is an asshole. It is just that assholes, by their
nature, are the loudest.

Hi all,

I have the task of testing some embedded 'C' code for a small micro-controller. Thought it would be a good idea to test it on the PC first to make sure the algorithm is correct then perhaps test it on the controller via RS232 and an appropriate wrapper round the 'C' functions.

On the PC I can use Python's unit test library module and logging to create a nice and easy to use environment (I like Python). So my question is how to communicate from Python to the C module on the PC. What I'd like is simplicity and ease of setting up. All I can think of myself is to use sockets.

Any ideas on how to do this would be gratefully appreciated.

Also as I don't have any microsoft offerings of a C compiler any suggestions as to a suitable C compiler for a PC appreciated as well. llvm? mingw? gcc?

Thanks a lot everyone,
John

Have a look at Cython:
http://cython.org/

This enables you to call C code from Python code within the same process.

I assume that by "PC" you mean Windows in which case mingw is a fine
choice and is officially supported by Cython.

Hi John,
I know this is not answering you question, but
have you considered using one of the many "C" unit
test programs that are available for testing the
embedded code? I would hazard to guess that it
would be much easier to use something that is
specifically C friendly that trying to adapt
Python unit test. You can however still use Python
as a wrapper or even a slick GUI for invoking the
C unit test using a subprocess and getting the
results. I have used CUnit in the past and I know
that it has several different methods for
returning the results. I'm sure other C unit test
programs are similar.

Visual Express C++ is fine, provided that its version matches your
version of Python. Failing that mingw is gcc for windows, then perhaps
cygwin. I know nothing about llvm.

Sockets are nice and simple. Depending on what you're doing,
stdin/stdout may be even simpler.

For the RS232 part of the problem, don't forget about pyserial:

I've occasionaly used mingw (which _is_ gcc), and it worked well.
Cygwin (also gcc) works well, but it's a bit more involved.

I do all my embedded development on a Linux host. I find Linux to be
far more suitable for the task -- the entire Unix system basically
evolved as a software development platform. I've yet to figure out
what MS-Windows is suited for other than lining Bill Gates' pockets.

Before Linux, I used Solaris/SunOS, and before that I used Unix V7.
Everytime I've been involved in a Microsoft-hosted embedded
development project, I just end up walking a way afterwards shaking my
head in puzzlement.

You can also use c-types for that

http://docs.python.org/2/library/ctypes.html#module-ctypes

I've used Python/ctypes to exercise libraries written in C, but I've
never done it under Windows. However, others have:

Thanks everyone for the advice, some good ideas to keep me busy. Will try and look at over weekend/next week as tied up the rest of today.

I've used pyserial several times - many thanks to Chris Liechti for that module

Hmmmmm must be loosing it, forgot about stdin/out!

I've also used CUnit before and it's nice an easy and small. Problem is I've only 500 bytes code space left on the micro-controller so by the time CUnit gone in with the various tests I'm gonna run of room. I have to keep the RS232 driver in as well as it's the only way to talk to the controller.

Python + pyserial enables me to run the tests with the C compiled and run on the PC as well as compiled to run on the micro-controller. Python is a great environment for doing this sort of thing and, as has been mentioned, a GUI can be added easily (time permitting).

Thanks again all,
John

Yes, this off-topic, but after a fair amount of Googling and searching
in the "right" places, I'm running out of ideas.

I've got a very feeble web server. The crypto handshaking involved in
opening an https: connection takes 2-3 seconds. That would be fine if
a browser opened a single connection and then sent a series of
requests on that connection to load the various elements on a page.

But that's not what browsers do. They all seem to open whole handful
of connections (often as many as 8-10) and try to load all the page's
elements in parallel. That turns what would be a 3-4 second page load
time (using a single connection) into a 20-30 second page load time.
Even with plaintext http: connections, the multi-connection page load
time is slower than the single-connection load time, but not by as
large a factor.

Some browsers have user-preference settings that limit the max number
of simultaneous connections to a single server (IIRC the RFCs suggest
a max of 4, but most browsers seem to default to a max of 8-16).

What I really need is an HTTP header or meta-tag or something that I
can use to tell clients to limit themselves to a single connection.

I haven't been able to find such a thing, but I'm hoping I've
overlooked something...
