  • OpenCV, Python (ctypes), and OS X 10.5: dylib errors/confusion

    - by Jeff
    I have tried two brands of ctypes (ctypes-opencv and another) wrappers for OpenCV (2.0 from svn head), can use Python and OpenCV in the Python console, but whenever I try to import the packages (from ctypes_opencv import *) from another Python file, I get the following error message: OSError: dlopen(/usr/local/lib/libcv.dylib, 6): Symbol not found: __ZN2cv10fastMallocEm Referenced from: /usr/local/lib/libcv.dylib Expected in: flat namespace And some more Python errors: module body in __init__.py at line 18 from ctypes_opencv.cxcore import * module body in cxcore.py at line 80 _cxDLL, _cvDLL, _hgDLL = detect_opencv() function detect_opencv in cxcore.py at line 59 cvDLL = cdll.LoadLibrary(find_lib('cv')) function LoadLibrary in __init__.py at line 431 return self._dlltype(name) function __init__ in __init__.py at line 353 self._handle = _dlopen(self._name, mode) I most recently built OpenCV using flags the ctypes_opencv wiki recommended: ENABLE_SSE(2) OFF and BUILD_NEW_PYTHON_SUPPORT OFF. I've tried a number of flag combinations though. I also tried using the MacPorts install of OpenCV, got the same messages, uninstalled it, and now it errors out as well. :P And if that wasn't enough, I tried using the latest ctypes wrapper, but get boost-jam errors. Any help would be very much appreciated.

  • Downgrading to pyobjc 2.0 from pyobjc 2.2

    - by maxdj
    I accidentally installed pyobjc 2.2 with easy-install pyobjc, and it's causing problems: When I try to import it I get the error Incompatible library version: _objc.so requires version 10.0.0 or later, but libxml2.2.dylib provides version 9.0.0 I'm not interested in fixing that though, all I want is my pyobjc 2.0 back. I've tried removing pyobjc 2.2 and reinstalling python, and I've tried building 2.0 from the svn trunk (I get the error lipo: can't figure out the architecture of [random filename].out) I imagine there must be a good way of doing this but it escapes me. Any insight would be appreciated. Edit: Python 2.6 and OSX 10.5

  • Merging columns in a JTable

    - by Harish
    I am working in JTable and I have a requirement like this. Say There are 4 columns namely 10,20,30,40 Now the value usually comes like 10-20 20-30 and 30-40 So it was easy for us to display the name for this range. But recently the values have started to come randomly like 15-25 10-25,25-30 In this case our JTable should dynamically adjust the size of the row such that it represents that range only meaning it should not disturb the existing cells and only rows which diverge from the normal range. TO be more precise I should be able to merge and split cells based on the content of the cell.

  • Suggestion for chkstk.asm stackoverflow exception in C++ with Visual Studio 2010

    - by Gulshan
    I am working with an implementation of merge sort. I am doing C++ Visual Studio 2010. But when I took a array of 300000 integers for timing, it is showing an unhandled stackoverflow exception and taking me to a readonly file named "chkstk.asm". I reduced the size to 200000 and it worked. Again the same code worked with C-free 4 editor (mingw 2.95) without any problem while the size was 400000. Do you have any suggestion to get the code working in Visual Studio? May be the recursion in the mergesort is causing the problem.

  • SQLServer Replication, dealing with updating data in a subscriber without merging with the publisher

    - by FlySwat
    To simplify my problem, picture two databases, one is a publisher, one is a replicated subscriber. Most of the time, changes are configured in the publisher, and pushed to the subscriber once per day using transactional replication. (The subscriber is the main production database). However, on a rare occasion, we need to make a change directly to the subscriber database. This does not break replication, however to ensure consistency, we also want to replicate this single change back to the publisher database. My first thought was to make both databases publishers to each other, but that does not work. Merge replication also does not work as that merges the data together, and we really only want to push that single change from the subscriber back to the publisher. Is there some other replication scheme I can use here, or do I need to invent my own thing?

  • Editing remote files over SSH, using TextMate?

    - by Zachary Burt
    I LOVE using TextMate on my MacBook. It's great. Unfortunately, I want to edit some files directly on my dev server, since it's difficult to recreate the environment locally. I'm using Git, so one alternative is to just edit locally, git commit, git push, and then git merge, but that's kind of complicated every time I want to make a simple change. I'd rather just ... use another solution. One thing I tried is mounting a hard drive via MacFusion, and then loading that in an editor. But that's so freaking laggy/slow! Has anyone cooked up a better solution?

  • Need an encrypted online source code backup service.

    - by camelCase
    Please note this is not a question about online/hosted SVN services. I am working on a home based, solo developer, project that now has commercial significance and it is time to think about remote source code backup. There is no need for file level check in/out, all I need is once a day or once a week directory level snapshot to remote storage. Automatic encryption would be a bonus to protect my IP. What I have in mind is some sort of GUI interface app that will squirt a source code snapshot off to an Amazon S3 bucket on an automatic schedule. (My development PC runs on MS Windows.)

  • Foundation framework. No NSString.h file

Could anyone tell me what happened? I tried to delete the framework and add it again but it failed to. Still I don't have NSString header file.

  • Semantic Diff Utilities

    - by rubancache
    I'm trying to find some good examples of semantic diff/merge utilities. The traditional paradigm of comparing source code files works by comparing lines and characters.. but are there any utilities out there (for any language) that actually consider the structure of code when comparing files? For example, existing diff programs will report "difference found at character 2 of line 125. File x contains v-o-i-d, where file y contains b-o-o-l". A specialized tool should be able to report "Return type of method doSomething() changed from void to bool". I would argue that this type of semantic information is actually what the user is looking for when comparing code, and should be the goal of next-generation progamming tools. Are there any examples of this in available tools?

  • Making vim git aware.

    - by anon
    I use Vim & Git together. I tend to merge/switch Git branches alot. I tend to have lots of vim buffers open. Is there a way to tell vim: when I execute this git command (which switches branches), reload all buffers? Since I have hooks into all my vim-git interaction, letting vim know when to do the reload is not a problem. The question is: how to force vim to reload all buffers?

  • merging two duplicate contacts/ColdFusion

    - by jil
    having to do with data integrity - I maintain a coldfusion database at a small shop that keeps addresses of different contacts. These contacts sometimes contain notes in them. When you are merging two duplicate contacts, one may be created in 2002 and one in 2008. If the contact in 2002 has notes prior to 2008, my question would be does it matter if you merge these contacts and keep the 2008 contact's ID number? Would that affect the data integrity or create any sort of issues with the notes earlier than 2008? I hope I've accurately described my scenario, as I am not familiar with the proper technical terms. I really appreciate the help sir!

  • Tables with no Primary Key

    - by Matt Hamilton
    I have several tables whose only unique data is a uniqueidentifier (a Guid) column. Because guids are non-sequential (and they're client-side generated so I can't use newsequentialid()), I have made a non-primary, non-clustered index on this ID field rather than giving the tables a clustered primary key. I'm wondering what the performance implications are for this approach. I've seen some people suggest that tables should have an auto-incrementing ("identity") int as a clustered primary key even if it doesn't have any meaning, as it means that the database engine itself can use that value to quickly look up a row instead of having to use a bookmark. My database is merge-replicated across a bunch of servers, so I've shied away from identity int columns as they're a bit hairy to get right in replication. What are your thoughts? Should tables have primary keys? Or is it ok to not have any clustered indexes if there are no sensible columns to index that way?

  • Tools to create maximum velocity in a .NET dev team

    - by Søren Spelling Lund
    If you were to self-fund a software project which tools, frameworks, components would you employ to ensure maximum productivity for the dev team and that the "real" problem is being worked on. What I'm looking for are low friction tools which get the job done with a minimum of fuss. Tools I'd characterize as such are SVN/TortioseSVN, ReSharper, VS itself. I'm looking for frameworks which solve the problems inherient in all software projects like ORM, logging, UI frameworks/components. An example on the UI side would be ASP.NET MVC vs WebForms vs MonoRail.

  • Should I use multiple ListViews?

    - by janfsd
    Hi to everybody! I have a RelativeLayout with different elements. I was planning to have two ListViews on it, but I have noticed there are some problems with scrolling. Since each ListView only shows a maximum of 5 rows should I try to make some kind of custom adapter to merge those ListViews? Or is it better to replace the ListView with a LinearLayout/RelativeLayout and add the rows as I get them manually? (like the first answer in here: http://stackoverflow.com/questions/1778485/android-listview-display-all-available-items-without-scroll-with-static-header ). Which should be the proper way on doing this? or is there another way? Also, each row will have an OnClickListener.

  • Recovering 'old commits' from multiple git rebases

    - by Benjol
    I am aware of this question, but not to sure how to map it to my current situation. (Rebase is scary, undoing rebase is double scary!) I started out with several different feature branches of my master: master x-x-x-x-x-x-x-x-x-x \ \ \ FeatureA 1-2-3 \ \ FeatureB A-B \ FeatureC X-Y-Z I wanted to merge them all together and check they worked before merging back onto the top of master, so I did a: git checkout FeatureB git rebase FeatureA git mergetool //etc git rebase --continue Then git checkout FeatureC git rebase FeatureB git mergetool //hack hack git rebase --continue Which leaves me with master x-x-x-x-x-x-x-x-x-x \ FeatureA 1-2-3 \ FeatureB A'-B' \ FeatureC X'-Y'-Z' Then I corrected some bits that didn't compile properly, and got the whole feature set to an acceptable state: master x-x-x-x-x-x-x-x-x-x \ FeatureA 1-2-3 \ FeatureB A'-B' \ FeatureC X'-Y'-Z'-W My problem is that my colleagues tell me that we're not ready for FeatureA. Is there any way for me to keep all my work, but also revert to a situation where I can just rebase FeatureC on to Feature B?

  • Adding barcodes to pdfs

    - by calccrypto
    is there any way to do something like a mail merge, where the data (9-15 chars long) is converted to a barcode? im using trying to use openoffice's code128 for calc, but for some reason, every 10 strings, the barcode goes crazy, and the ascii tells me to register at the site where the extension came from, which i dont want to do i also found one for oodraw, but that requires the values to be inputted manually. since im not familiar with the macros, i can't write something that will do it automatically what im trying to do is: take an old pdf (only 1 page) covert it to word or picture or something add a function/macro/whatever to show a barcode (whether or not the barcode shows in this file, i dont care), given a string from excel data reconvert to separate pdfs or some other way that adds barcodes to pdfs all other free programs i have found do not do this nicely, and since im not really a pdf person, im not going to buy random programs. i just need this done for one large batch of data

  • Fast partial sorting algorithm

    - by trican
    I'm looking for a fast way to do a partial sort of 81 numbers - Ideally I'm looking to extract the lowest 16 values (its not necessary for the 16 to be in the absolutely correct order). The target for this is dedicated hardware in an FPGA - so this slightly complicated matters as I want the area of the resultant implementation as small as possible. I looked at and implemented the odd-even merge sort algorithm, but I'm ideally looking for anything that might be more efficient for my needs (trade algorithm implementation size for a partial sort giving lowest 16, not necessarily in order as opposed to a full sort) Any suggestions would be very welcome Many thanks

  • Playing around with Eclipse features - Project files are now hidden?

    - by Daddy Warbox
    I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden trees altogether expanding when I click on any item, and the entire file folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?
