• getting "implicit declaration of function 'fcloseall' is invalid in C99" when compiling to gnu99

  - by Emanuel Ey

  Consider the following C code: #include <stdio.h> #include <stdlib.h> void fatal(const char* message){ /* Prints a message and terminates the program. Closes all open i/o streams before exiting. */ printf("%s\n", message); fcloseall(); exit(EXIT_FAILURE); } I'm using clang 2.8 to compile: clang -Wall -std=gnu99 -o <executable> <source.c> And get: implicit declaration of function 'fcloseall' is invalid in C99 Which is true, but i'm explicitly compiling to gnu99 [which should support fcloseall()], and not to c99. Although the code runs, I don like the have unresolved warnings when compiling. How can i solve this?

• good methods for boolean operations on overlapping polygons

  - by BenjaminGolder

  What is the best open source library for performing boolean operations (union, intersect, subtract) on shapefiles? What do you like to use? OGR looks like it probably has this capability, though I'm having trouble finding the particular commands in their documentation. Shapely definitely does this, and is easy to understand. PostGIS appears to also have some commands for this. But there must be more, and I'm having trouble finding them. I don't have much experience with any of the, and would appreciate any opinions on these or other libraries. Thanks!

• PyPy -- How can it possible beat CPython?

  - by Vulcan Eager

  From the Google Open Source Blog: PyPy is a reimplementation of Python in Python, using advanced techniques to try to attain better performance than CPython. Many years of hard work have finally paid off. Our speed results often beat CPython, ranging from being slightly slower, to speedups of up to 2x on real application code, to speedups of up to 10x on small benchmarks. How is this possible? Which Python implementation was used to implement PyPy? CPython? And what are the chances of a PyPyPy or PyPyPyPy beating their score? (On a related note... why would anyone try something like this?)

• Sublime Text LaTeXTools console autohide

  - by DCh

  The build script in the LaTeXTools plugin for Sublime Text editor pops up the console, where the result of the compilation is written. I would like the console to auto-hide once the compilation is finished and there are no errors (and to stay open otherwise). I knew how to achieve this with Sublime Text 2. (I think I inserted two lines sublime.active_window().run_command("show_panel", {"panel": "console", "toggle": True})) somewhere in the build script.) How to achieve this behavior with Sublime Text 3? How to (properly) achieve this behavior with Sublime Text 2?

• Project links in RAD Studio Welcome page do not work

  - by vcldeveloper

  Hi, As you know, welcome page in RAD Studio shows a list of recent projects, and you can open each project by clicking on its name. My problem is that if the project is located somewhere My Documents folder, then the link in welcome page does not work! It works fine for projects which are located outside My Documents, but no links to anything inside My Documents work. It's been a while I am having this problem both in RAD Studio 2009 and RAD Studio 2010 on Windows Vista and Windows 7 (64-bit). I tried running the IDE as administrator to see if it works, but it didn't. I think it must be something related to IE security settings. Any idea? Thanks

• Any good card game AI strategies?

  - by Mark

  What would be strategies for writing a good computer opponent for a card game? Most card games are games of incomplete information, so simply mapping out and traversing the game tree as one could do with a board game does not seem too promising. Maybe one could track what open cards are in the game (as soon as they are revealed) and assign probabilities to certain events (e.g. opponent still has 2 cards of clubs). Does anyone have experience with this? Links and directions greatly appreciated. Thanks! -Mark

• Preview man-page without installing package.

  - by bjarkef

  Hi I've checked out some typical open source project which is using auto-tools. I want to hack a bit on this package, but I would also like to change something in the man-page of the package. The man-page source is found project-name/doc/project-name.1. I just made a small change, and now I want to preview that change, without having to actually do a make install of the project. How do I do that? I tried stuff like: man -M . 1 project-name But it does not work, neither does the various variations I have tried. This sounds like a simple problem, but I can't seem to find anything by googling on the problem, so I'm hoping someone here can help me out. Thanks.

• Long-running transactions structured approach

  - by disown

  I'm looking for a structured approach to long-running (hours or more) transactions. As mentioned here, these type of interactions are usually handled by optimistic locking and manual merge strategies. It would be very handy to have some more structured approach to this type of problem using standard transactions. Various long-running interactions such as user registration, order confirmation etc. all have transaction-like semantics, and it is both error-prone and tedious to invent your own fragile manual roll-back and/or time-out/clean-up strategies. Taking a RDBMS as an example, I realize that it would be a major performance cost associated with keeping all the transactions open. As an alternative, I could imagine having a database supporting two isolation levels/strategies simultaneously, one for short-running and one for long-running conversations. Long-running conversations could then for instance have more strict limitations on data access to facilitate them taking more time (read-only semantics on some data, optimistic locking semantics etc). Are there any solutions which could do something similar?

• Reading from compressed lucene index

  - by Akhil

  I created a lucene index and compressed the index directory with bz2 or zip. I donot want to uncompress it. Is there any API call that can read the index from this zipped directory and thus allow searching and other functionalities. That is, can lucence IndexReader read the index from a compressed file. I saw that Lucnene IndexReader does not support "Reader" to open the index, otherwise I would have created a Reader class that uncompresses the file and streams the uncompressed version. Any alternatives to this are welcome. Thanks, Akhil

• Monitor RAM usage on CentOS and restart Apache at a certain usage

  - by Chris

  Hi, I'm running a CentOS 5.3 server with a basic LAMP stack. I've optimized LAMP and my code to run efficiently as possible, but Apache has a memory leak somewhere that kills my server every hour or so. What is the best way to write a script that will monitor the memory usage and if it peaks over, say, 450MB kill all the Apache processes and restart Apache. I know C++/PHP and basic Linux server administration but I'm not familiar with Perl or bash scripting. I'd be open to learn any solutions, though, as a temporary solution while I find the issue.

• Why isn't Expression Blend rendering my User Control? It's only showing XAML.

  - by unforgiven3

  I'm opening valid XAML within my VS2008 solution in Expression Blend 3 and it is only showing XAML when I try to open individual XAML files. My solution/projects all build and run correctly. When I go to View - Active Document View the Design View, Split View and XAML View options are all grayed out... which doesn't make much sense. I'm not much of a Blend user, but this has never happened before, and I'm coming up blank for how to fix it. Any ideas?

• jCarousel: Can you remove all items and rebind to a new collection?

  - by Jim G.

  jCarousel documentation states the following: By passing the callback function itemLoadCallback as configuration option, you are able to dynamically create (li) items for the content. {...} jCarousel contains a convenience method add() that can be passed the index of the item to create and the innerHTML string of the item to be created. My Question: Is it possible to remove all items and rebind to a new collection? BTW: I don't necessarily need a "convenience method" to do this. I'm very open to workarounds. FYI: This strategy doesn't seem to work.

• How to assemble a multi-project ant build system

  - by Alex Worden

  At my new gig, they use Ant and cannot be persuaded to move to Maven. I've looked everywhere for a decent example of how a multi-project ant build system should be assembled. The apache site falls short. I'm looking specifically for best practices to: Automatically build local projects that are dependencies of a project Share artifacts from project to their dependents Export a project's dependencies and generated artifacts (jars) to be inherited by dependent projects Share third-party dependencies between projects I'm sure I can do all this without using Ivy - what did people do before Ivy? I really don't want to have to set up a corporate repository or rely on external repositories - the engineers here are really against that and have all their third-party jars checked into src control. Can anyone point me at a good open source example of a multi-project ant build?

• I'm going to write 'Unit of Work', please help me find out all gimmicks

  - by o..o

  Hi everybody, I'm going to write my own DAL in C#. I decided to use 'Unit of Work' pattern (next mentioned as uow) with request as a scope and Identity map stored in HttpContext.Items. I have right now question about implementing of CRUD methods. How/where are they implemented? Are they implemented in every single business class (as in active records pattern) or are implemented somehow in uow class (if so, how)? I also suppose that I need to use as the scope not just the request, but also the db connection. But how? Should I open the connection a the start of the request and close it on uow disposing? Every advice is strongly appreciated, especially Your "real world" experiences. Thank you all :)

• Python 3 with the range function

  - by Leif Andersen

  I can type in the following code in the terminal, and it works: for i in range(5): print(i) And it will print: 0 1 2 3 4 as expected. However, I tried to write a script that does a similar thing: print(current_chunk.data) read_chunk(file, current_chunk) numVerts, numFaces, numEdges = current_chunk.data print(current_chunk.data) print(numVerts) for vertex in range(numVerts): print("Hello World") current_chunk.data is gained from the following method: def read_chunk(file, chunk): line = file.readline() while line.startswith('#'): line = file.readline() chunk.data = line.split() The output for this is: ['OFF'] ['490', '518', '0'] 490 Traceback (most recent call last): File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 88, in execute load_off(self.properties.path, context) File "/home/leif/src/install/linux2/.blender/scripts/io/import_scene_off.py", line 68, in load_off for vertex in range(numVerts): TypeError: 'str' object cannot be interpreted as an integer So, why isn't it spitting out Hello World 490 times? Or is the 490 being thought of as a string? I opened the file like this: def load_off(filename, context): file = open(filename, 'r')

• TFS: How to dectet changed files when loading a solution?

  - by marco.ragogna

  I am new to TFS integration with Visual Studio 2010, and I have a problem I would like to solve. Practically, when I open a solution, how can I detect, looking only at the Solution Explorer which file has been changed since my last login? I am able to discover the changed files if I look at the Latest column of Source Control Explorer but it is not so intuitive. I attach you an image for better understanding. I would like to have a different icon, not the lock, for frmAbout.vb (in this case), associated to the item in Solution Explorer. Do you have any idea how can I achieve this behavior? Or some alternatives?

• MapViewOfFile shared between 32bit and 64bit processes

  - by MK

  Hi, I'm trying to use MapViewOfFile in a 64 bit process on a file that is already mapped to memory of another 32 bit process. It fails and gives me an "access denied" error. Is this a known Windows limitation or am I doing something wrong? Same code works fine with 2 32bit processes. The code sort of looks like this: hMapFile = OpenFileMapping(FILE_MAP_ALL_ACCESS, FALSE, szShmName); if (NULL == hMapFile) { /* failed to open - create new (this happens in the 32 bit app) */ SECURITY_ATTRIBUTES sa; sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.bInheritHandle = FALSE; /* give access to members of administrators group */ BOOL success = ConvertStringSecurityDescriptorToSecurityDescriptor( "D:(A;OICI;GA;;;BA)", SDDL_REVISION_1, &(sa.lpSecurityDescriptor), NULL); HANDLE hShmFile = CreateFile(FILE_FAXCOM_SHM, FILE_ALL_ACCESS, 0, &sa, OPEN_ALWAYS, 0, NULL); hMapFile = CreateFileMapping(hShmFile, &sa, PAGE_READWRITE, 0, SHM_SIZE, szShmName); CloseHandle(hShmFile); } // this one fails in 64 bit app pShm = MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, SHM_SIZE);

• What does "Unatuthorized zone" mean when browsing xsd files with Visual Studio 2010?

  - by starskythehutch

  When I open up an xsd file that includes other xsd files, all of the included files are added to a section called "Unauthorized zone". Visual Studio highlights the element and gives the following error when trying to resolve the schemaLocation attribute: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I've read the following blog post, but I'm not familiar enough with xsd yet to fully understand it. Can anyone explain why this is happening or point me to a good resource that can help?

• Printing fails after first print with Centos 6 and HP LaserJet P3015dn printer

  - by Gavin Simpson

  Centos 6 recognises and configures a HP LaserJet P3015dn printer connected via USB. This machine is being configured as a small group file/print server. I can print a test page, which is processed/printed correctly. The next time printing is attempted (say printing a second test page), the page is not printed and the printer is set to disabled. The status of the printer is stated as: Stopped - /usr/lib/cups/backend/hp failed in the printer configuration dialogue. /var/log/cups/error_log contains this information (first two lines were there prior to the failed print job) E [24/Jun/2004:09:12:57 +0100] Returning HTTP Forbidden for Resume-Printer (ipp://localhost/printers/HP-LaserJet-P3010-Series) from localhost E [24/Jun/2004:09:20:59 +0100] Returning HTTP Forbidden for CUPS-Delete-Printer (ipp://localhost/printers/HP-LaserJet-P3010-Series) from localhost D [24/Jun/2004:09:37:28 +0100] [Job 28] The following messages were recorded from 09:36:43 AM to 09:37:28 AM D [24/Jun/2004:09:37:28 +0100] [Job 28] Adding start banner page "none".

• Cygwin command not found bad characters found in .bashrc 357\273\277

  - by mytwocents

  Hello, I'm new to Cygwin, I just installed it and attempted to set some simple environment variables. However, when I open the command shell, I get the error "#357\273\277 command not found" I found an article that discusses what the problem is and how to "discover" the hidden bad character: http://mblog.lib.umich.edu/DataDiscussions/archives/2010/01/index.html but I don't know how to resolve the issue by removing the character (which I validated was a problem in my .bashrc file using the od command). I attempted to change the preferences view in Notepad++ to UTF-8 and ANSI to no avail, but the file was not altered at all. Any help would be appreciated...

• Linker problem linking boost in Visual Studio 2008

  - by Tobias Langner

  Hi, I have a rather obscure linking problem in Visual Studio 2008. The linker error message is: "LNK1104: cannot open file 'boost_thread-vc90-mt-gd-1_38.lib'". All pathes and dependencies are set. What I noticed though is that Visual Studio misses boost_thread-vc90-mt-gd-1_38.lib and not libboost_thread-vc90-mt-gd-1_38.lib (notice the lib at the beginning of the file name). I added the .lib as libboost_thread-vc90-mt-gd-1_38.lib to the project and it appears as libboost_thread-vc90-mt-gd-1_38.lib in the command line. Why does Visual Studio the beginning of the file name?

• VCS File Downloading Issue with IE

  - by Sachin Gaur

  I am working on a http based (NOT Secure) Web Application. In this, I have provided a provision to add some appointment to the Client's outlook calendar. I am creating the .vcs file dynamically when clicked on a hyperlink. The code of generating .VCS file is: string calendarFormat = GetVCSFormat(); Response.ContentType = "text/calendar"; Response.AppendHeader("content-disposition", "attachment; filename=MyCalendar.vcs"); Response.Write(calendarFormat); Response.End(); It is working fine in all browsers except IE. It is giving me following error: Internet Explorer cannot download GenerateAppointment.aspx from server. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. Can anyone focus some light on it?

• Monodevelop SVN 1.7 support

  - by Gustavo Rubio

  I'm trying to checkout an SVN repo and it does get checked out, however the solution is not opened by default. I then tried to simply open an already checked out folder and I do not get versioning support. I tried this in both Windows and Linux with no success with MonoDevelop 3.0.4 and 3.0.5 My guess is that since the .sln file is in the path /trunk/code/project/project.sln and the new 1.7 format keeps only one ".svn" folder at the top of the checked out folder (e.g. /home/gustavo/ProjectSrc/ ) hence MD not "finding" the versioned code. Anybody has had success using SVN 1.7 and MonoDevelop?
