• Shaders with pygtkglext

  - by qba

  Do someone know how to get glsl shaders work in gtk-opengl window? With glut all glCreateProgram etc. functions works, but when I tried to put the same gl code into pygtkglext window, its complaining about NullReference: OpenGL.error.NullFunctionError: Attempt to call an undefined function glCreateProgram, check for bool(glCreateProgram) before calling So then I from OpenGL.GL.ARB.shader_objects import *, but the result is similar: OpenGL.error.NullFunctionError: Attempt to call an undefined function glCreateProgramObjectARB, check for bool(glCreateProgramObjectARB) before calling Any idea will be useful.

• Porting Java app to Go - any advice?

  - by Devrim

  We want to rewrite kodingen.com backend with Go which currently is Java, running as daemon using jsvc. I have never touched any C in my life, am only experienced in Java so I don't know if this is something that I should even start. However, task is pretty simple read shell commands from mysql database queue and execute them in parallel save each shell output to the database that's it. So these simple requirements gives me hope that I can start using this wonderful language. What would you advise?

• How to efficiently manage files on a filesystem in Java?

  - by Tuukka Mustonen

  I am creating a few JAX-WS endpoints, for which I want to save the received and sent messages for later inspection. To do this, I am planning to save the messages (XML files) into filesystem, in some sensible hierarchy. There will be hundreds, even thousands of files per day. I also need to store metadata for each file. I am considering to put the metadata (just a couple of fields) into database table, but the XML file content itself into files in a filesystem in order not to bloat the database with content data (that is seldomly read). Is there some simple library that helps me in saving, loading, deleting etc. the files? It's not that tricky to implement it myself, but I wonder if there are existing solutions? Just a simple library that already provides easy access to filesystem (preferrably over different operating systems). Or do I even need that, should I just go with raw/custom Java?

• Preserve "long" spaces in PDFBox text extraction

  - by Thilo

  I am using PDFBox to extract text from PDF. The PDF has a tabular structure, which is quite simple and columns are also very widely spaced from each-other This works really well, except that all kinds of horizontal space gets converted into a single space character, so that I cannot tell columns apart anymore (space within words in a column looks just like space between columns). I appreciate that a general solution is very hard, but in this case the columns are really far apart so that having a simple differentiation between "long spaces" and "space between words" would be enough. Is there a way to tell PDFBox to turn horizontal whitespace of more then x inches into something other than a single space? A proportional approach (x inch become y spaces) would also work.

• running a program in Unix vs in Windows

  - by Hristo

  I'm compiling a simple program written in C and I'm using Eclipse as an IDE, both in Windows 7 and on my MacBook Pro. Very simple program my friend wrote and asked me to help him with: int a = 0; char b[2]; printf("Input first class info:\n"); printf("Credit Hours: \n"); scanf("%d", &a); printf("Letter Grade: "); scanf("%s", b); So when I run this on my mac, each line prints and when I encounter the scanf(), I can input and continue as expected. In Windows, I have to input everything and then it will print all the lines. I'm not sure why this is happening... what is the difference b/w Windows and Mac here? Mac: Input first class info: Credit Hours: 4 Letter Grade: B+ Windows: 4 B+ Input first class info: Credit Hours: Letter Grade: Thanks, Hristo

• Using NSURLRequest+NSURLConnection seems overkill for a webcall with no data return

  - by Spectravideo328

  All, This might seems very straightforward but I have already gone through the URL loading system program guide and the various NSURL.... classes and not found my answer. I am just trying to do a simple call from the app to a website to reserve a party spot: NSString *path=[NSString stringWithFormat:@"http://www.myparty123.com/ireservedURL.asp?Nickname=%@&Seat=%i&Email=%@&Currentparty=%i",john,5432,[email protected],6598]; NSURL* reservationURL =[NSURL URLWithString:path]; NSData *call= [NSData dataWithContentsOfURL:reservationURL]; This seemed to be the simple way but I get this warning that I am not using the "call" variable. And it seems overkill to do a call using NSData where there is no data return. Yet, creating an NSURLRequest and initiating an NSURLConnection and then implementing delegates with that request seems to be overkill as well. What am I missing. Thanks KMB

• makefile compilation problem

  - by mistique

  He I have a problem with a makefile. I have three classes. They do pretty simple stuff. One does an addition on a subtraction, and the last one will instantiate the two and simply print the resulted addition and subtraction. Now when I create my makefile, I compile my Plus.java and my Minus.java but don't know how to compile the main class because it depends on the previous two. I want to compile and run it from the makefile if it's possible. I get the above results when I try to run make: javac -g Plus.class Minus.class javac: invalid flag: Plus.class Usage: javac use -help for a list of possible options make: * [Operation.class] Error 2 I don't know how to procede, please forgive me if my question is to simple but I am new working with these stuff. I've searched many sites but with no answer.

• English dictionary as txt or xml file with support of synonyms

  - by Simon

  Can someone point me to where I can download English dictionary as a txt or xml file. I am building a simple app for myself and looking for something what I could start using immediately without learning complex API. Support for synonyms would be great, that is it should be easier to retrieve all the synonyms for particular word. It would be absolutely fantastic if dictionary would be listing British and American spelling of the words where they are differ. Even if it would be small dictionary (few 000's words) that's ok, I only need it for small project. I even would be willing to buy one if the price is reasonable, and dictionary is easy to use - simple xml wold be great. Any directions please.

• Strange padding in Safari when using SVG images

  - by Naman Goel

  I thought I was having issues with margins but then on a closer look I found that SVGs are acting funky in Safari 6. I am building a simple Hexagon based website. Of course I used negative vertical margins to for a little overlap to 'inter-lock' the hexagons. And to save space I was using SVG images for the hexagons. It works great in chrome and firefox, but in Safari, there is a strange padding in the SVG images. I'm using simple img tags for the svg images. Everything works when I switch to PNG, but I'd prefer to stick to SVGs. Any insight? Can I perhaps delve into the SVG code and somehow fix the SVG problem in Safari? or is it some sort of bug, that I can do nothing about without browser sniffing?

• Refreshing Facebook session from an iframe application

  - by zombat

  I've got a Facebook iframe application that is completely external. By this I mean that once a user accesses the canvas URL to load the application, all the links in the iframe app go to my servers, and the canvas page never gets refreshed unless the user navigates to somewhere else on Facebook and comes back (or does a browser refresh). On the initial load of the app where Facebook creates the iframe, I get passed all the usual parameters like fb_sig_user which allows me to create an internal app session based on the facebook user. This app session (which is not the Facebook session, it's my own app session) is all I need to allow the user to work with the app. The problem comes an hour later. If the user leaves the computer, or uses the app for more than an hour, the Facebook session expires. There are some app pages which require fetching friend information, and once the FB session has expired, these pages break, throwing out errors such as "Error: Session key invalid or no longer valid". My question is whether there is a way to refresh the user's Facebook session from within an iframe application to keep it from expiring an hour later. Do any of the API calls do this? Is there a Facebook Connect trick to ping something? Is there any definitive method to keep it alive? I haven't been able to find any examples that specifically address this.

• lightweight publish/subscribe framework in java

  - by mdma

  Is there a good lightweight framework for java that provides the publish/subscribe pattern? Some ideal features Support for generics Registration of multiple subscribers to a publisher API primarily interfaces and some useful implementations purely in-memory, persistence and transaction guarantees not required. I know about JMS but that is overkill for my need. The publish/subscribed data are the result of scans of a file system, with scan results being fed to another component for processing, which are then processed before being fed to another and so on.

• Detect a file is closed

  - by User1

  Is there a simple way to detect when a file for writing is closed? I have a process that kicks out a new file every 5 seconds. I can not change the code for that process. I am writing another process to analyze the contents of each file immediately when it is created. Is there a simple way to watch a certain directory to see when a file is no longer opened for writing? I'm hoping for some sort of Linux command.

• Stata Nearest neighbor of percentile

  - by Kyle Billings

  This has probably already been answered, but I must just be searching for the wrong terms. Suppose I am using the built in Stata data set auto: sysuse auto, clear and say for example I am working with 1 independent and 1 dependent variable and I want to essentially compress down to the IQR elements, min, p(25), median, p(75), max... so I use command, keep weight mpg sum weight, detail return list local min=r(min) local lqr=r(p25) local med = r(p50) local uqr = r(p75) local max = r(max) keep if weight==`min' | weight==`max' | weight==`med' | weight==`lqr' | weight==`uqr' Hence, I want to compress the data set down to only those 5 observations, and for example in this situation the median is not actually an element of the weight vector. there is an observation above and an observation below (due to the definition of median this is no surprise). is there a way that I can tell stata to look for the nearest neighbor above the percentile. ie. if r(p50) is not an element of weight then search above that value for the next observation? The end result is I am trying to get the data down to 2 vectors, say weight and mpg such that for each of the 5 elements of weight in the IQR have their matching response in mpg. Any thoughts?

• What does the :compiler command do in Vim?

  - by Martín Fixman

  I recently found that there is a command in Vim called compiler. You can call it with any common compiler (for example, :compiler gcc, :compiler php, etc.), but it doesn't seem to have any immediate effect. I searched on the manpages but didn't find anything useful about what it actually does, nor does the Vim Wiki. Does anyone know what that command actually does?

• Problem running python/matplotlib in background after ending ssh session.

  - by Jamie

  Hi there, I have to VPN and then ssh from home to my work server and want to run a python script in the background, then log out of the ssh session. My script makes several histogram plots using matplotlib, and as long as I keep the connection open everything is fine, but if I log out I keep getting an error message in the log file I created for the script. File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 2058, in loglog ax = gca() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 582, in gca ax = gcf().gca(**kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 276, in gcf return figure() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 254, in figure **kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 90, in new_figure_manager window = Tk.Tk() File "/Home/eud/jmcohen/.local/lib/python2.5/lib-tk/Tkinter.py", line 1647, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display "localhost:10.0" I'm assuming that it doesn't know where to create the figures I want since I close my X11 ssh session. If I'm logged in while the script is running I don't see any figures popping up (although that's because I don't have the show() command in my script), and I thought that python uses tkinter to display figures. The way that I'm creating the figures is, loglog() hist(list,x) ylabel('y') xlabel('x') savefig('%s_hist.ps' %source.name) close() The script requires some initial input, so the way I'm running it in the background is python scriptToRun.py << start>& logfile.log& Is there a way around this, or do I just have to stay ssh'd into my machine? Thanks.

• Should a Unit-test replicate functionality or Test output?

  - by Daniel Beardsley

  I've run into this dilemma several times. Should my unit-tests duplicate the functionality of the method they are testing to verify it's integrity? OR Should unit tests strive to test the method with numerous manually created instances of inputs and expected outputs? I'm mainly asking the question for situations where the method you are testing is reasonably simple and it's proper operation can be verified by glancing at the code for a minute. Simplified example (in ruby): def concat_strings(str1, str2) return str1 + " AND " + str2 end Simplified functionality-replicating test for the above method: def test_concat_strings 10.times do str1 = random_string_generator str2 = random_string_generator assert_equal (str1 + " AND " + str2), concat_strings(str1, str2) end end I understand that most times the method you are testing won't be simple enough to justify doing it this way. But my question remains; is this a valid methodology in some circumstances (why or why not)?

• Set property on usercontrol that can be used in custom panel in control... Silverlight

  - by Dimestore Cowboy

  I have a simple usercontrol that uses a simple custom panel where I just overrode the Orientation and Measure functions. What I want to do is to have a property in the usercontol to control the orientation So I basicaly have UserControl -- Listbox -- MyPanel And I want a property for the usercontrol that can be set in xaml (of type System.Windows.Controls.Orientation ) that I can bind to from my custom panel (or a different approach if binding isnt the right way to do it) It would be a bonus if that property could show up in the properties window and you could select vertical or horizontal. And a super bonus if I could change the property at design time and have the listbox/

• Delphi component or library to display mathematical expressions

  - by Svein Bringsli

  I'm looking for a simple component that displays mathematical expressions in Delphi. When I started out I thought it would be easy to find something on the net, but it turns out it was harder than anticipated. There are lots and lots of components that will parse mathematical expressions, but few (none?) that will display them. Ideally I would like a component as simple as a TLabel, where I could set the caption to some expression and it would be displayed correctly, but some sort of library that let's me draw expressions to a canvas would also be sufficient for my needs. Update: I'm not talking about plotting graphs of functions or something like that. I want to display (for instance) (X^2+3)/X like this:

• Creating BlackBerry method stubs using wscompile on WSDL from ColdFusion

  - by Jim B

  I have been working on a BlackBerry application that consumes web services from ColdFusion 7. The Java ME SDK and the Java Wireless Toolkit both require that the generated WSDL be of the document/literal type. Fortunately, I have input on the web service development so I tried setting 'style="document"' in the cfcomponent tag. This generated a document/literal style WSDL but now wscompile generates the following errors in several places: Found unknown simple type: javax.xml.soap.SOAPElement Found unknown simple type: java.util.Calendar Any ideas why this is happening? The WSDL does get parsed correctly by the JWSDP tool but the stubs use namespaces that are not available in the J2ME platform. I would have thought ColdFusion WSDL would work more easily with other products in the Java family.

• SQLAlchemy - how to map against a read-only (or calculated) property

  - by Jeff Peck

  I'm trying to figure out how to map against a simple read-only property and have that property fire when I save to the database. A contrived example should make this more clear. First, a simple table: meta = MetaData() foo_table = Table('foo', meta, Column('id', String(3), primary_key=True), Column('description', String(64), nullable=False), Column('calculated_value', Integer, nullable=False), ) What I want to do is set up a class with a read-only property that will insert into the calculated_value column for me when I call session.commit()... import datetime def Foo(object): def __init__(self, id, description): self.id = id self.description = description @property def calculated_value(self): self._calculated_value = datetime.datetime.now().second + 10 return self._calculated_value According to the sqlalchemy docs, I think I am supposed to map this like so: mapper(Foo, foo_table, properties = { 'calculated_value' : synonym('_calculated_value', map_column=True) }) The problem with this is that _calculated_value is None until you access the calculated_value property. It appears that SQLAlchemy is not calling the property on insertion into the database, so I'm getting a None value instead. What is the correct way to map this so that the result of the "calculated_value" property is inserted into the foo table's "calculated_value" column?
