• Latex: Extracting the sty files of all the used packages

  - by Zlatko

  Hi. So after writhing a large .tex file and using many packages I want to archive everything. Not just the .tex .jpg files but also the .sty files. This is because sometimes some options in the sty files are changed, and then I can't compile the file. The "problem" is that in using Ubuntu, I already installed all the packages in my system. I don't want to have to copy the manually. Is there a program that can do this automatically. Tnx.

• Problems with contenttypes when loading a fixture in Django

  - by gerdemb

  I am having trouble loading Django fixtures into my MySQL database because of contenttypes conflicts. First I tried dumping the data from only my app like this: ./manage.py dumpdata escola > fixture.json but I kept getting missing foreign key problems, because my app "escola" uses tables from other applications. I kept adding additional apps until I got to this: ./manage.py dumpdata contenttypes auth escola > fixture.json Now the problem is the following constraint violation when I try to load the data as a test fixture: IntegrityError: (1062, "Duplicate entry 'escola-t23aluno' for key 2") It seems the problem is that Django is trying to dynamically recreate contenttypes with different primary key values that conflict with the primary key values from the fixture. This appears to be the same as bug documented here: http://code.djangoproject.com/ticket/7052 The problem is that the recommended workaround is to dump the contenttypes app which I'm already doing!? What gives? If it makes any difference I do have some custom model permissions as documented here: http://docs.djangoproject.com/en/dev/ref/models/options/#permissions

• How to reduce simple cpp application size? (compiled with RAD Studio 2010 cpp builder)

  - by peterg

  I am using rad studio 2010 cpp builder. I've created a new SDI application, added a TCppWebBrowser control and a simple button that onclick trigger the .navigate for the TCppWebBrowser, I compiled it and I got a 1.20mb file, I was expecting less than 700kb at least. How can I reduce the size of the compiled exe? I don't want to use "build with runtime packages", I know that will make it very small but I want to get all the necessary packages and dependencies inside the exe but maybe I am getting more than I use, I tried unchecking/removing a lot of design packages (in project/options/packages) I don't use but the file size didn't decreased. Also I was thinking maybe the TForm component that comes with RAD Studio is giving me more stuff than I need and that could make the file bigger, I mean I only need to drop a webbrowser control and a few buttons in the form, maybe there's a minimal form component I could use to replace TForm. Any suggestions will be appreciated.

• Better way to write this regex to match multi-ordered property list?

  - by Andrew Philips

  I've been whacking on this regex for a while, trying to build something that can pick out multiple ordered property values (DTSTART, DTEND, SUMMARY) from an .ics file. I have other options (like reading one line at a time and scanning), but wanted to build a single regex that can handle the whole thing. SAMPLE PERL # There has got to be a better way... my $x1 = '(?:^DTSTART[^\:]*:(?<dts>.*?)$)'; my $x2 = '(?:^DTEND[^\:]*:(?<dte>.*?)$)'; my $x3 = '(?:^SUMMARY[^\:]*:(?<dtn>.*?)$)'; my $fmt = "$x1.*$x2.*$x3|$x1.*$x3.*$x2|$x2.*$x1.*$x3|$x2.*$x3.*$x1|$x3.*$x1.*$x2|$x3.*$x2.*$x1"; if ($evts[1] =~ /$fmt/smo) { printf "lines:\n==>\n%s\n==>\n%s\n==>\n%s\n", $+{dts}, $+{dte}, $+{dtn}; } else { print "Failed.\n"; } SAMPLE DATA BEGIN:VEVENT UID:0A5ECBC3-CAFB-4CCE-91E3-247DF6C6652A TRANSP:OPAQUE SUMMARY:Gandalf_flinger1 DTEND:20071127T170005 DTSTART,lang=en_us:20071127T103000 DTSTAMP:20100325T003424Z X-APPLE-EWS-BUSYSTATUS:BUSY SEQUENCE:0 END:VEVENT SAMPLE OUTPUT lines: == 20071127T103000 == 20071127T170005 == Gandalf_flinger1

• Avoid generating empty STDOUT and STDERR files with Sun Grid Engine (SGE) and array jobs

  - by vy32

  I am running array jobs with Sun Grid Engine (SGE). My carefully scripted array job workers generate no stdout and no stderr when they function properly. Unfortunately, SGE insists on creating an empty stdout and stderr file for each run. Sun's manual states: STDOUT and STDERR of array job tasks will be written into dif- ferent files with the default location .['e'|'o']'.' In order to change this default, the -e and -o options (see above) can be used together with the pseudo-environment-vari- ables $HOME, $USER, $JOB_ID, $JOB_NAME, $HOSTNAME, and $SGE_TASK_ID. Note, that you can use the output redirection to divert the out- put of all tasks into the same file, but the result of this is undefined. I would like to have the output files suppressed if they are empty. Is there any way to do this?

• Best commercial libraries for developing NCPDP-based systems (prescription drug related)

  - by Kaveh Shahbazian

  What are (based on experiences) best commercial libraries for developing NCPDP-based systems? Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

• How to tell if XUL menupopup opens down or up?

  - by Jon

  I have an extension that can be placed on any toolbar (like the bookmarks, menu or status bars). In general, the context menu opens downward, but when placed on the status bar and Firefox is closed to the bottom of the screen, the context menu opens upward. I'd like to try reordering the context menu based on its up or down orientation, so that the same options are always closest to the mouse. For example, when opened downward it appears like this: -- (mouse) --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- When it opens upwards its like this: --------------- - MenuItem A - --------------- - MenuItem B - --------------- - MenuItem C - --------------- - ....... - --------------- -- (mouse) However, I'd like "MenuItem A" to appear closest to the mouse at all times, since its the most common item. I can render the items dynamically, so I really just need to find out the orientation.

• Bloomberg APIv3 returning Slow Consumer Warnings!

  - by Marcus

  I made a program in c# based on the example "SubscriptionWithEventHandlerExample" of API 3.2.9.0. After subscribing to about 500 securities for realtime data, I receive some ADMIN event warnings claiming SlowConsumerWarning and SlowConsumerWarningCleared. I read somewhere that it introduces some delay, until I process all events. The problem is that in my code I only receive callbacks from bloomberg. The event queue isn´t even in my program! Some things that I tried: 1) raise the queue limit, setting MaxEventQueueSize in the session options (seems to have no effect) 2) see if I get any timeout event (no, I don't get any) 3) create multiple sessions and subscribing 50 securities in each (now I get multiple warnings, one for each thread) Is there something that I can do or this behavior is out of my scope?

• VB.net, disable proxy for entire program

  - by Brent

  Ever since upgrading to Visual Studio 2010, I'm running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds before completing. Subsequent calls work quickly. I've narrowed down the problem to a proxy issue. If I manually disable proxy settings, I don't experience this delay: Dim wrq As WebRequest = WebRequest.Create(Url) wrq.Proxy = Nothing What's strange is that there are no proxy settings enabled on this machine in Internet Options. What I'm wondering is if there is a way to disable proxy settings for my entire project in one shot without explicitly disabling as above for every web object. The main reason I want to be able to do this is that I'm trying to use an API (http://code.google.com/p/google-api-for-dotnet/) which uses web requests, but does not provide any way to manually disable proxy settings. Can anyone point me in the right direction? Thanks!

• Processing incoming email

  - by Mike Schots

  How do I programmatically read an incoming email with .NET. I need a method to take the content of email message (in this case XML) on a POP server and read it into my application. Ideally this could be solved by: .NET code that I can run as a background task on my webserver to process the email. A service that can POST the contents of the email to my webserver. Although I'm open to other options. EDIT: Copied from the "non-answer": Currently, we're looking at using the email accounts our hosting company provides. Our own mail server could potentially be an option, but its something the we'd need to contact the host about.

When I open the server explorer for any windows application that I'm working on with VS 2008 and right click on data connections and then on add a connection a dialog comes up with available data providers. The problem is that SQL compact is not one of the options. Any idea why SQL compact is not showing up as a data provider in VS 2008?

• Text encoding problem between NSImage, NSData, and NSXMLDocument

  I'm attempting to take an NSImage and convert it to a string which I can write in an XML document. My current attempt looks something like this: [xmlDocument setCharacterEncoding: @"US-ASCII"]; NSData* data = [image TIFFRepresentation]; NSString* string = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; //Put string inside of NSXMLElement, write out NSXMLDocument. Reading back in looks something like this: NSXMLDocument* newXMLDocument = [[NSXMLDocument alloc] initWithData:data options:0 error:outError]; //Here's where it fails. I get: //Error Domain=NSXMLParserErrorDomain Code=9 UserInfo=0x100195310 "Line 7: Char 0x0 out of allowed range" I assume I'm missing something basic. What's up with this encoding issue?

• Avoiding improper std::string initialization with NULL const char* using g++

  - by pachanga

  A there any g++ options which can detect improper initialization of std::string with NULL const char*? I was in the process of turning some int fields into std::string ones, i.e: struct Foo { int id; Foo() : id(0) {} }; ...turned into: struct Foo { std::string id; Foo() : id(0) {} //oooops! }; I completely overlooked bad 'id' initialization with 0 and g++ gave me no warnings at all. This error was detected in the run time(std::string constructor threw an exception) but I'd really like to detect such stuff in the compile time. Is there any way?

• Space-based architecture?

  - by rcampbell

  One chapter in Pragmatic Programmer recommends looking at a blackboard/space-based architecture + a rules engine as a more flexible alternative to a traditional workflow system. The project I'm working on currently uses a workflow engine, but I'd like to evaluate alternatives. I really feel like a SBA would be a better solution to our business problems, but I'm worried about a total lack of community support/user base/venders/options. JavaSpaces is dead, and the JINI spin-off Apache River seems to be on life support. SemiSpace looks perfect, but it's a one-man show. The only viable solution seems to be GigaSpaces. I'd like to hear your thoughts on space based architecture and any experiences you've had with real world implementations.

• How to log python exception ?

  - by Maxim Veksler

  Hi, Coming from java, being familiar with logback I used to do try { ... catch (Exception e) { log("Error at X", e); } I would like the same functionality of being able to log the exception and the stacktrace into a file. How would you recommend me implementing this? Currently using boto logging infrastructre, boto.log.info(...) I've looked at some options and found out I can access the actual exception details using this code: import sys try: 1/0 except: exc_type, exc_value, exc_traceback = sys.exc_info() traceback.print_exception(exc_type, exc_value, exc_traceback) I would like to somehow get the string print_exception() throws to stdout so that I can log it. Thank you, Maxim.

• Is Oracle AQ/Streams of any use in my situation?

  - by RenderIn

  I'm writing a workflow system that is driven entirely at each step by explicit human interaction. That is, a task is assigned to a person, that person selects from a few limited options {approve, reject, forward}, and then it is either sent along to the next person or terminated. Just curious of Oracle Streams/AQ has anything to offer over flat tables managed by regular web application code. The amount of processing after each action is fairly limited and the volume is not terribly high, so there's not really a need to throttle things by throwing them into a queue. What are some of the benefits of introducing a queue structure, or is it overkill for my situation?

• Ways to save enums in database

  - by corgrath

  Hey guys. I am wondering what the best ways to save enums into a database is. I know there are name() and valueOf() methods to make it into a String back. But are there any other (flexible) options to store these values? Is there a smart way to make them into unique numbers (ordinal() is not safe to use)? Any comments and suggestions would be helpful :) Update: Thanks for all awesome and fast answers! It was as I suspected. However a note to 'toolkit'; That is one way. The problem is that I would have to add the same methods with each enum type i create. Thats a lot of duplicated code and, at the moment, Java does not support any solutions to this (You cannot let enum extend other classes). However, thanks for all answers!

Mostly because I don't live in the U.S. So I was wondering on how you best build applications in ASP.NET MVC and make it easily available to deploy on both IIS6 and IIS7. Keep in mind that this is for standard web-hosts, so there is no access to ISAPI-filters or special settings inside IIS6. Are there anything else one should think about when developing ASP.NET MVC-applications to target IIS6? Any functions that doesn't work? UPDATE: One of the bigger issues is the thing with routes. The pattern {controller}/{action} will work on IIS7, but not IIS6 which needs {controller}.mvc/{action}. So how do I make this transparent? Again, no ISAPI and no IIS-settings, please.
