• I need to debug my BrowserHelperObject (BHO) (in C++ with Visual Studio 2008) after a internet explo

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• Is there a way to send tracking info to Google Analytics from PHP ?

  - by seatoskyhk

  I have a PHP code that will return a image. the link is given to 3rd party. so, i need to keep track where the php request coming from. Because the PHP only return the image, I cannot use the Javascript code for Google analytics. I know that I can get the information from the access.log, but i think I can't dump the access.log to GA for analyzing, right? so, is there a way that I can do in PHP (e.g. sending a CURL ), send somethig to Google Analytics for tracking?

• How few a files does it take to load a program on Linux?

  - by BCS

  The (hypothetical for now) situation is the user of my system is going to be given a chunk of C code and needs my system to compile and run it in a chroot sandbox that is generated on the fly and I want to require the fewest files in the box as possible. I'm only willing to play with compiler and linker settings (e.g. static link everything I can expect to be able to find) and make some moderate restriction on what the code can expect use (e.g. they can't use arbitrary libs). The question is how simple can I get the sandbox. Clearly I need the executable, but what about an ELF loader and a .so for the system calls? Can I dump either of them and is there something else I'll need?

• How do you save a Neural Network to file using Ruby's ai4r gem?

  - by Jaime Bellmyer

  I'm using ruby's ai4r gem, building a neural network. Version 1.1 of the gem allowed me to simply do a Marshal.dump(network) to a file, and I could load the network back up whenever I wanted. With version 1.9 a couple years later, I'm no longer able to do this. It generates this error when I try: no marshal_dump is defined for class Proc I know the reason for the error - Marshal can't handle procs in an object. Fair enough. So is there something built in to ai4r? I've been searching with no luck. I can't imagine any practical use for a neural network you have to rebuild from scratch every time you want to use it.

• identify documents from results of mahout clustering

  - by Tejas

  I am using mahout to cluster text documents indexed using solr. I have used the "text" field in the document to form vectors. Then I used the k-means driver in mahout for clustering and then the clusterdumper utility to dump the results. I am having difficulty in understanding the output results from the dumper. I could see the clusters formed with term vectors in those clusters. But how do I extract the documents from these clusters. I want the result to be the input documents appearing in different clusters.

• How to make django test framework read from live database?

  - by lfborjas

  I realize there's a similar question here, but this one has a different approach: I have a django app that does queries over data indexed with djapian ; I'd like to write unit tests for this app's search component, and, obviously, I'd need the django settings module and all connections with the database active, so the test runner that django provides seems ideal. however, the django testing framework creates a dummy database and I'd hate to dump all my data to a fixture and then index it (the tests would take forever!); My data isn't at risk because the tests would only read from the database, so, how could this be achieved? -I'm new at this whole unit testing thing, so the solution of writing a new test runner I read in that similar question doesn't enlighten me a bit, at least not without some details

• alter mysqldump file before import

  - by julio

  Hi-- I have a mysqldump file created from an earlier version of a product that can't be imported into a new version of the product, since the db structure has changed slightly (mainly altering a column that was NOT NULL DEFAULT 0 to UNIQUE KEY DEFAULT NULL). If I just import the old dump file, it will error out since the column that has default values of 0 now breaks the UNIQUE constraint. It would be easy enough to either manually alter the mysqldump file, or import into a temp table and change it, then copy to the new table. However, is there a way to do this programatically, so it will be repeatable and not manual? (this will need to happen for many instances of this product). I'm thinking something like disabling key constraints for the import, then setting all values that = 0 to NULL, then re-enabling the key constraints? Is this possible? Any help appreciated.

• Is a program compiled with -g gcc flag slower than the same program compiled without -g?

  - by e271p314

  I'm compiling a program with -O3 for performance and -g for debug symbols (in case of crash I can use the core dump). One thing bothers me a lot, does the -g option results in a performance penalty? When I look on the output of the compilation with and without -g, I see that the output without -g is 80% smaller than the output of the compilation with -g. If the extra space goes for the debug symbols, I don't care about it (I guess) since this part is not used during runtime. But if for each instruction in the compilation output without -g I need to do 4 more instructions in the compilation output with -g than I certainly prefer to stop using -g option even at the cost of not being able to process core dumps. How to know the size of the debug symbols section inside the program and in general does compilation with -g creates a program which runs slower than the same code compiled without -g?

• Mysqld shutting down by itself

  - by AJ Naidas

  I'm running a Wordpress Blog that gets medium-high traffic. It is hosted in an Ubuntu Server 2GB Memory 2 Core Processor 40GB SSD Disk, 3TB Transfer. The problem is that MySQL shuts down by itself after an hour or two. I had to restart mysql each and every time this happens. I checked the logs and this is what I found: 140612 6:48:14 [Warning] Using unique option prefix myisam-recover instead of myisam-recover-options is deprecated and will be removed in a future release. Please use the full name instead. 140612 6:48:14 [Note] Plugin 'FEDERATED' is disabled. 140612 6:48:14 InnoDB: The InnoDB memory heap is disabled 140612 6:48:14 InnoDB: Mutexes and rw_locks use GCC atomic builtins 140612 6:48:14 InnoDB: Compressed tables use zlib 1.2.3.4 140612 6:48:14 InnoDB: Initializing buffer pool, size = 1.4G InnoDB: mmap(1502412800 bytes) failed; errno 12 140612 6:48:14 InnoDB: Completed initialization of buffer pool 140612 6:48:14 InnoDB: Fatal error: cannot allocate memory for the buffer pool 140612 6:48:14 [ERROR] Plugin 'InnoDB' init function returned error. 140612 6:48:14 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 140612 6:48:14 [ERROR] Unknown/unsupported storage engine: InnoDB 140612 6:48:14 [ERROR] Aborting 140612 6:48:14 [Note] /usr/sbin/mysqld: Shutdown complete judging by this line: 140612 6:48:14 InnoDB: Fatal error: cannot allocate memory for the buffer pool I suspect that this is a memory problem, but I would like to hear from the experts here before I conclude. Is this a lack of memory problem? Do you think the value of max_connections in my.cnf (currently 100) is a potential cause and needs increasing? TIA.

• Programatticaly grabing text from a web page that is dynamically generated.

  - by bstullkid

  There is a website I am trying to pull information from in perl, however the section of the page I need is being generated using javascript so all you see in the source is <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it!

• Why is rails setting ":null => false" on all my columns in schema.rb?

  - by ryeguy

  Even if I never specify :null => false in my migrations that initially add columns to tables, rails still generates code in schema.rb that specifies the columns as having :null => false. Why is this? If I develop on my box, and then use rake db:schema:load on my production box, I'm going to get very different behavior! Edit: Even if I delete schema.rb and run rake db:schema:dump, it still puts :null => false on the new schema even if it isn't defined like that in the actual database. It seems it can't tell whether or not a column is marked as allowing nulls. I'm using SQLite if that helps.

• Cache an FTP connection via session variables for use via AJAX?

  - by Chad Johnson

  I'm working on a Ruby web Application that uses the Net::FTP library. One part of it allows users to interact with an FTP site via AJAX. When the user does something, and AJAX call is made, and then Ruby reconnects to the FTP server, performs an action, and outputs information. Every time the AJAX call is made, Ruby has to reconnect to the FTP server, and that's slow. Is there a way I could cache this FTP connection? I've tried caching in the session hash, but "We're sorry, but something went wrong" is displayed, and a TCP dump is outputted in my logs whenever I attempt to store it in the session hash. I haven't tried memcache yet. Any suggestions?

• How to replicate this screenshot in WebForms?

  - by AngryHacker

  I need to replicate the following in ASP.NET WebForms using a GridView. But I am not sure where to start. Basically I need 3 columns. The checkbox (which sometimes needs to be disabled), and 2 standard text columns. I've gone through the tutorial and I can see how to basically dump text data into a GridView, but not clear on how to implement checkboxes, particularly ones that needs to be disabled once in a while. And I have to replicate the style of the screenshot (e.g. border on the bottom). Having trouble with that as well. How do I swing something like that?

• How do I back up a remote SVN repository

  - by Roaders

  Hi all I am currently moving my SVN server from my home server to my remote server so I can access it more easily from other locations. My remote server is not backed up so I want to regularly back it up to my home server. Remote server is Windows 2003 server. Home server is Windows Home Server. What is the best way to do this? can I get my home server to get a dump of the remote server every night? Bandwidth isn't a huge consideration but if I could just copy any new checkins to an SVN server on my home server that would be fine. Any suggestions welcome. Thanks

• Out of memory errors but not actually out of memory...

  - by commradepolski

  So, myself and my fellow support techs have been fighting with this issue and we still dont know what the problem is. Lets start off with the system specs: Windows XP 32 bit Corporate (SP2 and SP3) Intel D975XBX2 Mobo 4gb of ram Intel Core 2 Quad Q6600 ATI Radeon HD 3600 - 512mb After a few hours of working on the machine, the end user will begin to see the following symptoms: Out of memory messages Title bars and menus dont draw in properly Problems accessing network resources Problems opening up documents such as MSWord and MSPowerpoint and text files Problems opening up explorer windows General instability We have looked at task manager while this issue was occurring, and all indicators, like PF usage, threads, handles, etc. are normal. We have been having trouble pinpointing the root cause of this issue. It is also not situated with one user, it affects 8-10. So far we have tried: Resetting CMOS (Waiting to see results) Replacing video card (didnt help) Windows updates (didnt help) Updating network drivers (didnt help) Switching user from 1gbps to 100mbps network connection (awaiting results) Swapping the affected user's hardware (waiting for results) Increasing desktop heap size (helped for a bit but then the issue became more frequent) Applying the /3 switch to XP (didnt help) Increasing and decreasing and setting PF to system managed state (didnt help) We did have a power outage at the office a couple weeks ago, and all these issues became more frequent. Prior to the power outage it may take a week or so for the users to experience the issues but since the power outage it takes 3-4 hours or less. We havent had reports of the above issues causing BSODs, although that would be easier to diagnose :). Any help is greatly appreciated.

• Return an object after parsing xml with SAX

  - by sentimental_turtle

  I have some large XML files to parse and have created an object class to contain my relevant data. Unfortunately, I am unsure how to return the object for later processing. Right now I pickle my data and moments later depickle the object for access. This seems wasteful, and there surely must be a way of grabbing my data without hitting the disk. def endElement(self, name): if name == "info": # done collecting this iteration self.data.setX(self.x) self.data.setY(self.y) elif name == "lastTagOfInterest": # done with file # want to return my object from here filehandler = open(self.outputname + ".pi", "w") pickle.dump(self.data, filehandler) filehandler.close() I have tried putting a return statement in my endElement tag, but that does not seem to get passed up the chain to where I call the SAX parser. Thanks for any tips.

• Generate "Finder.h" for a SIMBL plugin

  I'm trying to create a SIMBL plugin for Finder to add icon overlay over some files. I have this code: @implementation NSObject (FAIconOverlay) - (void)FAIconOverlay_TIconAndTextCell_drawIconWithFrame:(struct CGRect)arg1 { [self FAIconOverlay_TIconAndTextCell_drawIconWithFrame:arg1]; if (![self respondsToSelector:@selector(node)]) { return; } NSLog(@"%@", [[[NSClassFromString(@"FINode") nodeWithFENode:[(TNodeIconAndNameCell *)self node]] fullPath] lastPathComponent]); // Draw the icon overlay } - (void)FAIconOverlay_TDesktopIcon_drawIconInContext:(struct CGContext *)arg1 { [self FAIconOverlay_TDesktopIcon_drawIconInContext:arg1]; } @end I can draw the icon overlay but, when I try to get the path of the file I get a "Use of undeclared identifier TNodeIconAndNameCell". Looking this link < How to Write OS X Finder plugin I see that is neccessary to generate a Finder.h file... My question is: How to generate this file?? I tried running "class-dump -H Finder.app" but I get too more compiling errors Thank you very much!

• how to write floating value accurately to a bin file.

  - by user319873

  Hi I am trying to dump the floating point values from my program to a bin file. Since I can't use any stdlib function, I am thinking of writting it char by char to a big char array which I am dumping in my test application to a file. It's like float a=3132.000001; I will be dumping this to a char array in 4 bytes. Code example would be:- if((a < 1.0) && (a > 1.0) || (a > -1.0 && a < 0.0)) a = a*1000000 // 6 bit fraction part. Can you please help me writting this in a better way.

• How can I select a value matching my input from a TypeAhead control using WWW::Mechanize?

  - by kyoob

  So ordinarily the element I want to pick from a list would be populated on a page and I'd just find it and pick it. But I'm dealing with a control that doesn't populate list elements until some input has been stuck into a text box, after which it gives me a list of recommendations. For an example of the kind of list I'm talking about think of Facebook's "People, Places, and Things" search field. I want to plug a string into this text box, select the same string from the list of recommendations, and submit the form. The issue I'm having right now is I can't seem to get Mechanize to even recognize the field is there. I examine a dump of $mech->find_all_inputs and it isn't listed. Is this kind of field just beyond Mechanize's jurisdiction?
