Network/multi-user program
So... this is a fairly general / hypothetical question, and I'm more looking for direction than specifics - though it may be useful as well. I need to create a particular application for administering a sporting event. 95% (and this may be understating the case) of the 'users' would likely be single-machine, single user scenarios. For those exceptions (which are important enough that I'm concerned over them) there would be one person 'administering' the event and a small number of others (probably 5, no more than 10) doing basic data entry - competitor registration and later entering scores. Before (setting up event), in between (squadding competitors based on classification, equipment, available positions on relays, etc.) and taking care of final reports for awards, etc. would be done only from the main program. The end-users are likely not tech-saavy, and most likely running Windows or maybe a Mac. Being able to do the data entry from a tablet would be nice but by no means necessary. Installation needs to be as stone-simple as possible - running from a pre-configured USB stick or a browser would be ideal. Use would be over small wired or wi-fi LAN enviroment - no exposure to Internet. Given that the vast majority of the 'work' is going to be done on one computer by one user, but wanting to retain the flexibility/ability to later have addtional 'clients' connect for data entry purposes... I'm trying to decide what would be a better option: create a stand-alone GUI desktop app and figure out how to create a separate 'client' program that can connect and perform basic CRUD operations, or start out with some sort of web framework and have everything literally run from the 'server' via a browser-based interface. The scope of the project in terms of users appears to be small enough that using something like sqlite would be feasible (the data entry clients would not be working on the same records), and the small development web servers that most projects like web2py, flask, django come with should (maybe?) be able to carry the (minimal) load as well. Having to throw html/css/js plus browser compatibility issues on top of everything else starts making the project look a whole lot bigger than I'm comfortable with... but on the other hand I have no idea how to go about connecting a client app to a running GUI program either. The whole project is fairly ambitious for my current skill level (basically small addressbook/task-list type apps) but I figured I'd have to stretch/grow a bit either way I go. So I guess I'm asking for advice or simplified examples of how to go about connecting a client desktop app to a parent/master desktop app, so I can get some idea of how big of a task I'm looking at here, and whether that would be more or less difficult than trying to do the equivalent job using a web framework.

Easier way: Don't have a master desktop app, but instead have a master database. Since you're posting this to python-list, I'll assume you currently intend writing this in Python; you can make a really simple transition from single-user-single-desktop to a networked system, although of course you'll want to think in terms of multiple users from the start. So... if everybody is using the same application to access the same database, how would you prevent say, a data entry user from accidentally breaking something above their pay-grade?

As others point out, you can filter the spam fairly easily with a good client program. You don't get (as much of) that kind of spam in forums, depending on the authentication process and the vigilance of the forum staff/moderators.

Yeah, decent filters and storage can mute a lot of that, but not as effeciently as reading the groups via news.gmane.org which provides a mail2news gateway for a lot of mailing lists like this one.

Re: PyQT app accessible over network?
Yes, I am looking at a database-centric application. I know that the 'larger' databases such as PostgreSQL, MySQL, etc. would not have any problem handling that small amount of traffic. My concern is that using postgres or mysql for this would be akin to using a sledgehammer to swat a fly, when sqlite could most likely handle the load well enough (I think) since the handful of people doing data entry would rarely (if ever) be trying to write to the same record. That would be the whole point of having multiple people doing data entry in this situation - each one handling a different competitors entry form or submitted scores. My other reason for wanting one 'central' app is that there are various functions (setting up the tournament, closing registration, editing scores, finalizing results) that I really *don't* want the satellite/client apps to be able to do. My personal view is that sort of thing needs to be handled from one point, by one person (the match director or chief stats officer, depending on the size of the event). That is why I was looking at things in terms of having one central app that handles the database, whether locally via sqlite or postgres or whatever, but have the clients access go through that main application in order to ensure that all they have is a limited set of CRUD abilities for competitor registration and entering scores. Thanks for the links... some of those I was already aware of (Camelot, Dabo) but some of the others are new (QtAlchemy, etc). Should make for interesting reading!

PyQT app accessible over network?
Hello all, New guy here, with a kind of general question. Hopefully its not too silly... I've been working at learning python off and on now for a while, with a couple programs in mind as a goal - kind of specialized stuff that I can't seem to find a good match for already available, competitor records, score-keeping results for an amateur sports tournament. Many places use some cobbled-together Excel spreadsheet, which has its limitations. Others use an antiquated DOS-style application written in PowerBasic that has issues of its own. Probably 98-99% of the time the match administration would be done by a single individual on a single PC, which seems like it would be nearly ideal for a desktop application implemented in PyQt4 or similar. The problem is (as usual) those edge cases where there are enough volunteers/resources to have more than one person doing data entry (maybe 2-3 in practice, but lets say 10-12 for arguments sake to pad things a bit). What I was wondering is what would be a good way of handling this with a PyQt app? Build the desktop app first, and add some sort of functionality to enable a lightweight web server and framework for the additional data entry 'clients'? Or would it be better to create dedicated PyQt client apps to connect to the PC/laptop running the 'main' application? Should I go a different direction entirely, with a complete self-hosted webapp built on a framework like web2py? As you can probably tell, I have only a vaguely fuzzy idea of 'how' at this point... but I would like to be able to proceed with some confidence that as I get further down the road I'm not going to run into a dead-end and have to start over down a different path.

I assume other smart editors have similar capabilities. Different tools
have different combinations of these, or slightly different

It makes a huge difference in how productive you are.
While I probably don't use the vast majority of the 'fancy' features of
most IDEs - most of what I do barely requires any real 'project
manangement'... there are a couple things that I've gotten *very* used
to with an IDE.
One is having it run pylint and pep8 checks against code, display the
output in a friendly format with links straight to the offending items
and even displaying colored carats in the gutter region and
high-lighting them.
The other is having it parse my imports, and use them for the
'auto-complete' aka 'code intelligence' features - and not just the
standard library stuff, but also GUI toolkits like PyQt4.
I'm pretty sure those things can be done, or something fairly close at
least, in editors like vim or emacs... but the few times I looked into
it for vim, it was enough to send me running back to Eclipse/PyDev, even
if it is kind of an 800lb gorilla otherwise.

'Experimental Design' aka DoE
Hello, I'm interested in refining some tests I do for a hobby of mine beyond the traditional 'one factor at a time' (OFAT) method. I have been looking at 'design of experiment' (DoE) methods and they look promising. The problem is that most of the software packages that aid in the setup and analysis of this sort of thing are rather expensive (the cheapest is an Excel plugin that runs ~$250, and they go up from there rapidly). I've found some limited DoE support in R and SciLab, but I'd like to stick with Python if possible. So far though, I haven't been able to find hardly any mention of the topic, even searching through lists for numpy, scipy, pydata, statsmodel, etc. Given the hype that I've always seen about Python being used in science engineering fields, it seems like there should be *something* already out there...

One book that helps me out quite a bit is John Zelle's Python Programming: An Introduction to Computer Science.

Well... partly because Excel is not exactly cross-platform. Granted, the mass majority of people using a program like I have in mind will be doing so on Windows, but I was hoping to *not* tie things to any one platform if I could avoid it. Probably an overly ambitious goal at this point. The other part... maybe its my relative newbie experience level showing here, but having to call/open Excel to print something from a python app feels a little like admitting that python can't do it in a reasonable manner. If I wanted to have to open Excel to print out the results, I think I'd just as soon spend the effort and make the whole thing an Excel/VBA app and skip python entirely. Perhaps (probably) I'm not understanding some of how the lower level systems stuff works here... I thought the print drivers were there to take care of the low-level device-specific communication, and provide a somewhat simplified common interface for regular programs like M$ Word, Open Office, Adobe Reader, etc. to use. Those programs don't access the hardware directly, do they? Don't they hand off the print job to the OS-specific print drivers, and let them handle the spooling, etc.? From my (admittedly limited) understanding of things on Windows, Mac Linux, that seems to be somewhat common between platforms. Isn't there some sort of module in Python to do the same? I could understand it needing to be somewhat *platform* specific, perhaps... but I have old copies of M$ Office 2003 printing out just duckily on printers that only came out on the market less than a year ago. I updated the printer drivers and changed the default printer, but nothing printer-related in Word or Excel changed (that I know of)... but it still manages to hand off to the operating system print drivers just fine... which is kind of what I figured Python would do. Is that (to some degree) what ReportLab does? TIA, Monte -- http://mail.python.org/mailman/listinfo/python-list

They need access to GUI libraries which python doesn't expose out of the box. I know the usual response to what I'm about to say is Knock yourself out, let us know when you have something workable but I have to say it anyways... wow, that seems like such a gaping hole that I can't hardly believe its not filled. Printing final results is a *huge* part of what I'm wanting to do. Seems like it'd be a huge opportunity for someone wanting to improve/contribute to python, or like one of the 'summer of code' projects, etc. So as sad as it may sound - going through some native program such as excel or acrobat to perform the printing might be your best bet. Opening Adobe Reader as a sort of 'print preview' might be a workable solution... since the results will likely need to be a) archived and b) emailed out to the group. -- http://mail.python.org/mailman/listinfo/python-list

It seems that at least the cheaper models from Brother and Dymo accept a bitmap in specific dimensions and they print it pixel exactly. Very simple, in other words. But different printers need different formats, which is why there are printer drivers. I'd assume the DOS program you mention supports a very specific Dymo printer? Honestly, I don't know. The interface of that program usually has me grinding my teeth within minutes. It was written years ago, and is in fact now being updated... to a 'new' version of BASIC (still with a 'DOS' interface) only because the existing version will not run on anything newer than Win XP due to memory issues (assuming I understood the problem correctly). I was looking today and see that Dymo makes a SDK available that is supposed to be cross-platform (more specifically, download the SDK for the platform you want to use), but given the age of this setup... I'm guessing it was probably hard-coded to a particular device. The labels are sliding backwards into the 'nice to have' category. Being able to print out the final results sheets (one or two pages at the end of the day) is the primary goal at this point. Anyways, for operating systems using CUPS for printing (that would be Mac OS X, Linux, *BSD at least), there seems to be pycups which wraps the CUPS API. From a quick study of http://timgolden.me.uk/python/win32_how_do_i/print.html, it looks like in Windows you can just use the win32 APIs for printing, which is hard. An easier alternative seems to be using PIL to generate a DIB with your data in it and printing that. Actually... for the results sheet, the shellExecute method he described just might work. -- http://mail.python.org/mailman/listinfo/python-list

This ups your work to get involved with a web framework, but it lets you provide your application to users without the need to install. It also makes it totally platform agnostic Actually, this was kind of the way I originally started out (albeit looking at PHP MySQL), for exactly those reasons, except one - the installation. Everything else - the gui would be in a familiar browser frame of reference, and a lot of the get-this/send-that would be a bit simpler, plus it would be an extension of what I know (and am still learning) with html/css. The installation is the big snafu. This isn't something I can install on a remote server and just have the users (tournament coordinators and their data entry helpers) connect to over the internet. 99% of the time, it will be one person on one computer at a location that is lucky if they have a 110VAC power outlet nearby. Any kind of external network access short of a cell modem is pretty much out of the question. LAN/Wifi access between machines for some parallel data entry would be nice, but still asking a lot. Expecting the end user (volunteers) to install/configure Apache server, MySQL server, Python, and Django starts to sound to be a little far-fetched. I'd had some hope for cherrypy or web2py since they appear to provide a local http server without needing all the ancilliary stuff... somehow I didn't get the impression Django worked that way? -- http://mail.python.org/mailman/listinfo/python-list
Printing forms and labels in Python
Hello, I'm still a relative newbie to python, so I apologize if this is covered in detail somewhere and I missed it. I have a program or two that I want to work on once I get more proficient with python and sqlite and tkinter/wxpython. One of the big 'features' of those programs I want to make is going to be printing out match results (scores) from a competition along with competitor names and other pertinent information. Currently most people are doing this in Excel, though there is one (old) DOS program written in BASIC that not only prints the match results and the reports for the sanctioning body, but also prints labels via a Dymo Label maker. I realized today that one thing I have never seen covered in any Python tutorial is how to format and print things to a physical printer. I did a little bit of searching and didn't come up with much... either I'm really not using the right search terms, or physical printing is a black hole/art...?

What I was trying to say was I don't get the point of paying for an account on a provider clear across the country simply for the sake of getting Usenet access... especially when more and more large institutions are shutting theirs down (i.e. the death knoll for usenet as others have pointed out).

Time to let it go. True. Decent NNTP access is harder to find. Not impossible, but no longer a 'free' part of most standard ISP access any more. Gmane provides a mail-to- nntp gateway which is great for those who like to read it via nntp. Most people use this list via e-mail, which everyone has access to and knows how to use. The best solution I've seen is what is used by the Mono project; which provides both a web forum and a mail list interface. http://lists.ximian.com/mailman/listinfo/mono-list http://go-mono.com/forums/ It works very well; and everyone [except the 3 or 4 NNTP hold outs] are happy.
