• Pylucene in Python 2.6 + MacOs Snow Leopard

  - by jbastos

  Greetings, I'm trying to install Pylucene on my 32-bit python running on Snow Leopard. I compiled JCC with success. But I get warnings while making pylucene: ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/__init__.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/__wrap01__.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/__wrap02__.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/__wrap03__.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/functions.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/JArray.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/JObject.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/lucene.o, file is not of required architecture ld: warning: in build/temp.macosx-10.6-i386-2.6/build/_lucene/types.o, file is not of required architecture ld: warning: in /Developer/SDKs/MacOSX10.4u.sdk/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/JCC-2.3-py2.6-macosx-10.3-fat.egg/libjcc.dylib, file is not of required architecture ld: warning: in /Developer/SDKs/MacOSX10.4u.sdk/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/JCC-2.3-py2.6-macosx-10.3-fat.egg/libjcc.dylib, file is not of required architecture build of complete Then I try to import lucene: MacBookPro:~/tmp/trunk python Python 2.6.3 (r263:75184, Oct 2 2009, 07:56:03) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import pylucene Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named pylucene >>> import lucene Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/lucene-2.9.0-py2.6-macosx-10.6-i386.egg/lucene/__init__.py", line 7, in <module> import _lucene ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/lucene-2.9.0-py2.6-macosx-10.6-i386.egg/lucene/_lucene.so, 2): Symbol not found: __Z8getVMEnvP7_object Referenced from: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/lucene-2.9.0-py2.6-macosx-10.6-i386.egg/lucene/_lucene.so Expected in: flat namespace in /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/lucene-2.9.0-py2.6-macosx-10.6-i386.egg/lucene/_lucene.so >>> Any hints?

• Best pattern to load enumerated values from DAL using WCF RIA Services

  - by Dale Halliwell

  I would like to be able to load several RIA entitysets in a single call without chaining/nesting several small LoadOperations together so that they load sequentially. I have several pages that have a number of comboboxes on them. These comboboxes are populated with static values from a database (for example status values). Right now I preload these values in my VM by one method that strings together a series of LoadOperations for each type that I want to load. For example: public void LoadEnums() { context.Load(context.GetMyStatusValues1Query()).Completed += (s, e) => { this.StatusValues1 = context.StatusValues1; context.Load(context.GetMyStatusValues2()).Completed += (s1, e1) => { this.StatusValues2 = context.StatusValues2; context.Load(context.GetMyStatusValues3Query()).Completed += (s2, e2) => { this.StatusValues3 = context.StatusValues3; (....and so on) }; }; }; }; While this works fine, it seems a bit nasty. Also, I would like to know when the last loadoperation completes so that I can load whatever entity I want to work on after this, so that these enumerated values resolve properly in form elements like comboboxes and listboxes. (I think) I can't do this easily above without creating a delegate and calling that on the completion of the last loadoperation. So my question is: does anyone out there know a better pattern to use, ideally where I can load all my static entitysets in a single LoadOperation?

• Style list of divs as 2 column layout with css

  - by Anders Svensson

  I'm trying out ASP.NET MVC 2 by going through the "NerdDinner" tutorial. But apparently version 2 of MVC doesn't create a Details page the same as in the tutorial, and you get divs with css classes on them to style. However, I want to get the style where each label is followed on the same line with the field, and I can't do it, I get them on top of each other, or if I try using floats weird things happen (probably because I don't know exactly how to use it in this situation, where every other div should be on the same line). Here's the generated html for the Details page: <fieldset> <legend>Fields</legend> <div> <div class="display-label">DinnerID</div> <div class="display-field"><%: Model.DinnerID %></div> <div class="display-label">Title</div> <div class="display-field"><%: Model.Title %></div> <div class="display-label">EventDate</div> <div class="display-field"><%: String.Format("{0:g}", Model.EventDate) %></div> <div class="display-label">Description</div> <div class="display-field"><%: Model.Description %></div> <div class="display-label">HostedBy</div> <div class="display-field"><%: Model.HostedBy %></div> <div class="display-label">ContactPhone</div> <div class="display-field"><%: Model.ContactPhone %></div> <div class="display-label">Address</div> <div class="display-field"><%: Model.Address %></div> <div class="display-label">Country</div> <div class="display-field"><%: Model.Country %></div> <div class="display-label">Latitude</div> <div class="display-field"><%: String.Format("{0:F}", Model.Latitude) %></div> <div class="display-label">Longitude</div> <div class="display-field"><%: String.Format("{0:F}", Model.Longitude) %></div> <div class="display-label">IsValid</div> <div class="display-field"><%: Model.IsValid %></div> </div> </fieldset> How do I get the display-label and display-field for each "entry" to appear on the same line?

• Any HTTP proxies with explicit, configurable support for request/response buffering and delayed conn

  - by Carlos Carrasco

  When dealing with mobile clients it is very common to have multisecond delays during the transmission of HTTP requests. If you are serving pages or services out of a prefork Apache the child processes will be tied up for seconds serving a single mobile client, even if your app server logic is done in 5ms. I am looking for a HTTP server, balancer or proxy server that supports the following: A request arrives to the proxy. The proxy starts buffering in RAM or in disk the request, including headers and POST/PUT bodies. The proxy DOES NOT open a connection to the backend server. This is probably the most important part. The proxy server stops buffering the request when: A size limit has been reached (say, 4KB), or The request has been received completely, headers and body Only now, with (part of) the request in memory, a connection is opened to the backend and the request is relayed. The backend sends back the response. Again the proxy server starts buffering it immediately (up to a more generous size, say 64KB.) Since the proxy has a big enough buffer the backend response is stored completely in the proxy server in a matter of miliseconds, and the backend process/thread is free to process more requests. The backend connection is immediately closed. The proxy sends back the response to the mobile client, as fast or as slow as it is capable of, without having a connection to the backend tying up resources. I am fairly sure you can do 4-6 with Squid, and nginx appears to support 1-3 (and looks like fairly unique in this respect). My question is: is there any proxy server that empathizes these buffering and not-opening-connections-until-ready capabilities? Maybe there is just a bit of Apache config-fu that makes this buffering behaviour trivial? Any of them that it is not a dinosaur like Squid and that supports a lean single-process, asynchronous, event-based execution model? (Siderant: I would be using nginx but it doesn't support chunked POST bodies, making it useless for serving stuff to mobile clients. Yes cheap 50$ handsets love chunked POSTs... sigh)

• LINQ query code for complex merging of data.

  - by Stacey

  I've posted this before, but I worded it poorly. I'm trying again with a more well thought out structure. Re-writing this a bit to make it more clear. I have the following code and I am trying to figure out the shorter linq expression to do it 'inline'. Please examine the "Run()" method near the bottom. I am attempting to understand how to join two dictionaries together based on a matching identifier in one of the objects - so that I can use the query in this sort of syntax. var selected = from a in items.List() // etc. etc. select a; This is my class structure. The Run() method is what I am trying to simplify. I basically need to do this conversion inline in a couple of places, and I wanted to simplify it a great deal so that I can define it more 'cleanly'. class TModel { public Guid Id { get; set; } } class TModels : List<TModel> { } class TValue { } class TStorage { public Dictionary<Guid, TValue> Items { get; set; } } class TArranged { public Dictionary<TModel, TValue> Items { get; set; } } static class Repository { static public TItem Single<TItem, TCollection>(Predicate<TItem> expression) { return default(TItem); // access logic. } } class Sample { public void Run() { TStorage tStorage = new TStorage(); // access tStorage logic here. Dictionary<TModel, TValue> d = new Dictionary<TModel, TValue>(); foreach (KeyValuePair<Guid, TValue> kv in tStorage.Items) { d.Add(Repository.Single<TModel, TModels>(m => m.Id == kv.Key),kv.Value); } } }

• Mercurial in Windows doesn't see .hgignore - why?

  - by AP257

  Windows fails to pick up my .hgignore file. I'm running Mercurial from the command line, and "hg status" shows lots of files in the ignored directories. The .hgignore file looks like this (there's no whitespace at the start of the file, or at the start of each line). I've put it in the root directory of the repository. \.pyc$ \.pyo$ \.DS_Store \.Python \.installed.cfg ^bin$ ^build$ ^develop-eggs$ ^eggs$ ^include$ ^lib$ ^parts$ ^pip-log.txt$ ^web/localsettings.py$ I've tried saving the file in ANSI and UTF-8, and it doesn't seem to make a difference. I know the file is working OK on Linux, is there anything different about the paths in Windows?

• Python encoding for pipe.communicate

  - by Brian M. Hunt

  I'm calling pipe.communicate from Python's subprocess module from Python 2.6. I get the following error from this code: from subprocess import Popen pipe = Popen(cwd) pipe.communicate( data ) For an arbitrary cwd, and where data that contains unicode (specifically 0xE9): Exec. exception: 'ascii' codec can't encode character u'\xe9' in position 507: ordinal not in range(128) Traceback (most recent call last): ... stdout, stderr = pipe.communicate( data ) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 671, in communicate return self._communicate(input) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1177, in _communicate bytes_written = os.write(self.stdin.fileno(), chunk) This is happening, I presume, because pipe.communicate() is expecting ASCII encoded string, but data is unicode. Is this the problem I'm encountering, and i sthere a way to pass unicode to pipe.communicate()? Thank you for reading! Brian

• Using boost.python to import a method with opencv calls but failing due to symbols not being found a

  - by nmz787

  So I don't have the code right now, as I am not home... but i used the boost library for python in C++ to allow python to access a function called something like loadImageIntoMainWindow(string filepath) in the C++ source code the method calls opencv methods that are imported at the top of the file, I included opencv in my Jamroot file, and also found a way to compile and link manually on the command line... in either case when I run my python file it complains that the symbols aren't found for the first function call to an opencv method... I will update as soon as I get home with the C++, the command line compilation lines, the Jamroot, and the python files

• Can I use an opened gzip file with Popen in Python?

  I have a little command line tool that reads from stdin. On the command line I would run either... ./foo < bar or ... cat bar | ./foo With a gziped file I can run zcat bar.gz | ./foo in Python I can do ... Popen(["./foo", ], stdin=open('bar'), stdout=PIPE, stderr=PIPE) but I can't do import gzip Popen(["./foo", ], stdin=gzip.open('bar'), stdout=PIPE, stderr=PIPE) I wind up having to run p0 = Popen(["zcat", "bar"], stdout=PIPE, stderr=PIPE) Popen(["./foo", ], stdin=p0.stdout, stdout=PIPE, stderr=PIPE) Am I doing something wrong? Why can't I use gzip.open('bar') as an stdin arg to Popen?

• Is there a way to convert a swf to an .abc file?

  - by Jeremy Ruppel

  I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J

• embed ttf as embeded resource can't reference it

  Hi, I've just added a ttf file to the project (c# 2008 express) as "file" and build option to embeded resource.

• PyQt4: Why does Python crash on close when using QTreeWidgetItem?

  - by Rini

  I'm using Python 3.1.1 and PyQt4 (not sure how to get that version number?). Python is crashing whenever I exit my application. I've seen this before as a garbage collection issue, but this time I'm not sure how to correct the problem. This code crashes: import sys from PyQt4 import QtGui class MyWindow(QtGui.QMainWindow): def __init__(self, parent=None): QtGui.QMainWindow.__init__(self, parent) self.tree = QtGui.QTreeWidget(self) self.setCentralWidget(self.tree) QtGui.QTreeWidgetItem(self.tree) # This line is the problem self.show() app = QtGui.QApplication(sys.argv) mw = MyWindow() sys.exit(app.exec_()) If I remove the commented line, the code exits without a problem. If I remove the 'self.tree' parent from the initialization, the code exits without a problem. If I try to use self.tree.addTopLevelItem, the code crashes again. What could be the problem?

• Ruby: Is there a better way to iterate over multiple (big) files?

  - by zxcvbnm

  Here's what I'm doing (sorry for the variable names, I'm not using those in my code): File.open("out_file_1.txt", "w") do |out_1| File.open("out_file_2.txt", "w") do |out_2| File.open_and_process("in_file_1.txt", "r") do |in_1| File.open_and_process("in_file_2.txt", "r") do |in_2| while line_1 = in_1.gets do line_2 = in_2.gets #input files have the same number of lines #process data and output to files end end end end end The open_and_process method is just to open the file and close it once it's done. It's taken from the pickaxe book. Anyway, the main problem is that the code is nested too deeply. I can't load all the files' contents into memory, so I have to iterate line by line. Is there a better way to do this? Or at least prettify it?

• VS development on FDCC compliant Workstation

  Hi, I have a FDCC compliant workstation with FIPS 140-1 (Level 1) enabled. Now, i cannot run/debug any VS 2005/2008 applications on my machine I get the following error message on my browser Parser Error Message: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms. the Error points to line no 1 of default.aspx.cs file using system; The only way to successfully debug/run my application is to set the following registry key to 0 HKLM\System\CurrentControlSet\Control\Lsa\fipsalgorithmpolicy I understand that there are some Cryptographic algorithms that are not FIPS compliant on XP SP2 but i am not using cryptography at all. For that matter, the solution contains just default.aspx page with default code in .cs file, and even that fails to run. So my question is why the webpage fails to load, and why the error points to line #1 "using System;" statement? My next question is how can i develop on FIPS compliant locked down maching where i do not have edit rights on registry Thanks kudlur

• UpdateAllViews() from within a worker thread?

  - by Harvey

  I have a worker thread in a class that is owned by a ChildView. (I intend to move this to the Doc eventually.) When the worker thread completes a task I want all the views to be updated. How can I make a call to tell the Doc to issue an UpdateAllViews()? Or is there a better approach? Thank you. Added by OP: I am looking for a simple solution. The App is running on a single user, single CPU computer and does not need network (or Internet) access. There is nothing to cause a deadlock. I think I would like to have the worker thread post (or send) a message to cause the views to update. Everything I read about threading seems way more complicated than what I need - and, yes, I understand that all those precautions are necessary for applications that are running in multiprocessor, multiuser, client-server systems, etc. But none of those apply in my situation. I am just stuck at getting the right combination of getting the window handle, posting the message and responding to the message in the right functions and classes to compile and function at all.

• Getting XML data from a external page and parsing it with PHP

  I'm trying to create a database of World of Warcraft gems. If I go to this page: http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items And go to View Source in Firefox, I see a tonne of XML data which is exactly what I want.

After that, I create cairo context and draw some lines and destroy the cairo. I return 'TRUE' as return value of callback function so that expose-event does not propagate. Now my problem is, I am drawing line from (0,0) to (100,100). But line appears only over the border areas of the gtkentry. The place where text is, it does not appear. Please help. Kind Regards -Durgesh O Mishra

• Filtering out emoticons using sed

  - by user349222

  Hello, I have a grep expression using cygwin grep on Win. grep -a "\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u" all_fbs.txt > rockon_fbs.txt Once I identify the emoticon class, however, I want to strip them out of the data. However, the same regexp above within a sed results in a syntax error (yes, I realize I could use /d instead of //g, but this doesn't make a difference, I still get the error.) sed "s/\(\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u\)*//g" The full line is: grep -a "\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u" all_fbs.txt | sed "s/\(\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u\)*//g" | sed "s/^/ROCKON\t/" > rockon_fbs.txt The result is: sed: -e expression #1, char 14: unknown option to `s' I know it's coming from the sed regexp I'm asking about it b/c if I remove that portion of the full line, then I get no error (but, of course, the emoticons are not filtered out). Thanks in advance, Steve

• installing simplejson on the google appengine

  - by user266564

  Super nub question time! I am trying to use simplejson on the google appengine. In a terminal on my machine I have simplejson installed and working. But my when I try to import it in a script running on the appengine I get an error saying no such library exists. If open the interactive console on my machine (from the link on http://localhost:8080/_ah/admin) and type "import simplejson" I get: Traceback (most recent call last): File "/home/chris/google_appengine/google/appengine/ext/admin/init.py", line 210, in post exec(compiled_code, globals()) File "", line 1, in ImportError: No module named simplejson Any thoughts?

• C#, WPF. Length of string that will fit in a specific width.

  - by Ian

  Hi, I'm sure I'm missing something obvious, I have an area in which I intend to draw text. I know its (the area) height and width. I wish to know how many characters/Words will fit in the width, characters preferably. Second question, If the line is too long I'll want to draw a second line, so I guess I need to get the height of the text as well, including what ever it considers the right vertical padding? I'd also rather like to know the inverse, i.e. how many characters I can fit in a specific width. I assume the fact that WPF isn't constrained to pixels will have some bearing on the answer? Ultimately I'm planning on wrapping text around irregular shaped images embedded in the text. Any pointers in the right direction would be great. Thanks
