• How do I determine the cause of Qt's "*** is not a valid Qt plugin" error?

  - by chadjoan

  When I print the value of errorString from my QPluginLoader object, I get this: The file 'C:/pyprojects/test/qsqlpsqld4.dll' is not a valid Qt plugin. I would like to avoid some days worth of doing the time consuming "guess-and-check" methodology that my current internet searches reveal (so far none of them seem relevant anyways). Is there a way for me to get the Qt library itself to tell me why it is refusing to load this plugin? I don't want to guess; I want to know. Context: I am on Windows 7 running Qt 4.8.5 (32-bit, MinGW) and the qsqlpsqld4.dll file is also 32-bit and compiled with MinGW. I am using PySide to interact with Qt.

• Best place to store large amounts of session data

  - by audiopleb

  I'm building an application that needs to store and re-use large amounts of data per session. So for example, the user selects a large list of list items (say 2000 or significantly more) which have a numeric value as their key then they save that selection and go off to another page, do something else and then come back to the original page and need to load their selections into that page. What is the quickest and most efficient way of storing and reusing that data? In a text file saved with the session id? In a temp db table? In the session data itself (db sessions so size isn't a limit) using a serialised string or using gzcompress or gzencode? Any advice or insight would be great! Thank you!!!!

• Bash: any command to replace strings in text files?

  - by mikez302

  I have a hierarchy of directories containing many text files. I would like to search for a particular text string every time it comes up in one of the files, and replace it with another string. For example, I may want to replace every occurrence of the string "Coke" with "Pepsi". Does anyone know how to do this? I am wondering if there is some sort of Bash command that can do this without having to load all these files in an editor, or come up with a more complex script to do it. I found this page explaining a trick using sed, but it doesn't seem to work in files in subdirectories.

• Length of data returned from CGImageGetDataProvider is larger than expected

  - by jcoplan

  I'm loading a grayscale png image and I want to access the underlying pixel data. However after I load get the pixel data via CGImageGetDataProvider, the length of the data returned is longer than expected. CCGDataProviderRef provider = CGDataProviderCreateWithFilename(cStr); CGImageRef image = CGImageCreateWithPNGDataProvider(provider, NULL, FALSE, kCGRenderingIntentDefault); mapWidth = CGImageGetWidth(image); mapHeight = CGImageGetHeight(image); lookupMap = CGDataProviderCopyData(CGImageGetDataProvider(image)); mapWidth comes out to 1804 and mapHeight comes out to 1005. The product of which is 1813020 When I call CFDataGetLength(lookupMap) the response is 1833120. Where are these extra 20100 bytes coming from? Any help here is much appreciated. Am I missing something about the underlying format of the image?

• What is the correct way to bootstrap Drupal with Kohana 3?

  - by Dave

  Hi, I am trying to implement single sign on between an existing Drupal site a Kohana 3 based webapp. Ideally I would like to load Drupal's session information into $GLOBALS using the bootstap: require_once('../includes/bootstrap.inc'); drupal_bootstrap(DRUPAL_BOOTSTRAP_SESSION); A post on the Kohana forum suggested that this should be placed in Kohana's index.php, but didn't say where. I've tried right at the start, and just before Kohana's own bootstrap, but both result in a White Screen of Death. Changing the bootstrap level to DRUPAL_BOOTSTRAP_CONFIGURATION works, but the session data isn't loaded. Any bootstrap level above DRUPAL_BOOTSTRAP_ACCESS results in a WSOD. If anyone has any ideas I'd really appreciate it!

• Starting an ASP.NET MVC 4 project. Is it necessary to use RequireJS if I'm using bundling?

  - by SCS

  If RequireJS makes it so that multiple js files are combined into a single main.js file, is it essentially the same as ASP.NET's script bundling functionality? Would the only bonus of using RequireJS in addition to bundling be the ability to have certain scripts be loaded according to RequireJS configuration? I'm very new to both bundling and RequireJS, but after doing some reading, it seems like bundling takes care of multiple requests to load several js files. Are there any other things I might be missing out on with regards to using RequireJS with bundling?

• OS monitoring using JAVA

  - by Puneri

  I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

• Removing an object in a child collection in MongoDB

  - by Jeremy B.

  I've got a collection of content. Said collection has a collection of responses as such Content : [{ 'id' : '1234', 'Responses' : [{ 'id' : '12345' } etc. Now, I want to remove response 12345, but I don't want to remove all of the responses. I can't seem to find the command to do so. I'm getting the impression that the correct action is to grab the object, rebuild the Responses without the one I want removed, and then save the Content object as a whole. Provided there are many responses, this seems like a bad practice to have to load the entire object that way.

• MEMORY(HEAP) vs. InnoDB in a Read and Write Envirnment

  - by Johannes

  I want to programm a real-time application using MySQL. It needs a small table (less than 10000 rows) that will be under heavy read (scan) and write (update and some insert/delete) load. I am really speaking of 10000 updates or selects per second. These statements will be executed on only a few (less than 10) open mysql connections. The table is small and does not contain any data that needs to be stored on disk. So I ask which is faster: InnoDB or MEMORY (HEAP)? My thoughts are: Both enginges will probably serve SELECTs directly from memory, as even InnoDB will cache the whole table. What about the UPDATAEs? (innodb_flush_log_at_trx_commit?) My main concern is the locking behavior: InnoDB row lock vs. MEMORY table lock. Will this present the bottleneck in the MEMORY implementation? Thanks for your thoughts!

• mysql does not utilize my cpu and ram enough?

  - by vick

  Hello Everyone! I am importing a 2.5gb csv file to a mysql table. My storage engine is innodb. Here is the script: use xxx; DROP TABLE IF EXISTS `xxx`.`xxx`; CREATE TABLE `xxx`.`xxx` ( `xxx_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(128) NOT NULL, `yy` varchar(128) NOT NULL, `yyy` varchar(64) NOT NULL, `yyyy` varchar(2) NOT NULL, `yyyyy` varchar(10) NOT NULL, `url` varchar(64) NOT NULL, `p` varchar(10) NOT NULL, `pp` varchar(10) NOT NULL, `category` varchar(256) NOT NULL, `flag` varchar(4) NOT NULL, PRIMARY KEY (`xxx_id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; set autocommit = 0; load data local infile '/home/xxx/raw.csv' into table company fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n' ( name, yy, yyy, yyyy, yyyyy, url, p, pp, category, flag ); commit; Why does my PC (core i7 920 with 6gb ram) only consume 9% cpu power and 60% ram when running these queries?

• Horizontal Scaling of Tomcat in Microsoft Azure

  - by Fabe

  Hey everyone, I am working on this quiet a while, but still no conclustion. I want to do horizontal scaling of Tomcat instances in Microsoft Azure (1,2,3,... Tomcat instances for one service). I read lots of articles about session replication, clustering,... with Tomcat. Since Azure does not support Multicasts, there is no easy way to cluster Tomcat. Also sticky sessions is no options, because Azure does round robin load balancing. Setting up two services - one with Terracotta or Apache mod_jk - and the other with Tomcat instances seems overkill for me (if even doable)... Is this even possible? Thanks in advance for reading and answering my question. Every comment/idea is highly appreciated.

• make db connection persistent throught zend framework

  - by kamikaze_pilot

  I'm using zend framework. currently everytime I need to use the db I go ahead and connect to the DB: function connect(){ $connParams = array("host" => $host, "port" => $port, "username" => $username, "password" => $password, "dbname" => $dbname); $db = new Zend_Db_Adapter_Pdo_Mysql($connParams); return $db } so I would just call the connect() function everytime I need to use the db My question is...suppose I want to reuse $db everywhere in my site and only connect once in the very initial stage of the site load and then close the connection right before the site gets sent to the user, what would be the best practice to accomplish this? Which file in Zend should I save $db in, what method should I use to save it (global variable?), and which file should I do the connection closing in?

• emacs: is there a semantic-jump-to-declaration (using semantic.el)?

  - by Cheeso

  Suppose I am editing a buffer containing C code. I have started semantic with semantic-load-enable-code-helpers . I have point placed on the name of a function . If I then invoke senator-jump I can jump to the place where that fn is first declared, in that module. What if it is an extern? Is it possible to use senator to jump to the definition of the fn, which resides in a separate module? Thanks.

• Why do I have a page hit for 404.php after each legitimate pagehit?

  - by Nathan Long

  I'm working with an intranet system that, on each page, checks the user's cookie, verifies that they can see the current page based on database permissions, and records a page hit that includes their id and the page URL. I just noticed that in the pagehits table, I see an entry for 404.php (my custom 404 page specified in the Apache config) one second after each legitimate page hit. Is this probably my fault, or does it have something to do with how Apache decides to load the 404 page? I'm using Apache 2.2.14 (Win32) and PHP 5.3.2.

• Java or Python distributed compute job (on a student budget)?

  - by midget_sadhu

  I have a large dataset (c. 40G) that I want to use for some NLP (largely embarrassingly parallel) over a couple of computers in the lab, to which i do not have root access, and only 1G of user space. I experimented with hadoop, but of course this was dead in the water-- the data is stored on an external usb hard drive, and i cant load it on to the dfs because of the 1G user space cap. I have been looking into a couple of python based options (as I'd rather use NLTK instead of Java's lingpipe if I can help it), and it seems distributed compute options look like: Ipython DISCO After my hadoop experience, i am trying to make sure i try and make an informed choice -- any help on what might be more appropriate would be greatly appreciated. Amazon's EC2 etc not really an option, as i have next to no budget.

• reading and writing QByteArrays

  - by synchronicity

  I'm having trouble reading and writing QByteArray data to a file. My goal is to save QPixmap data into a QByteArray and save that QByteArray to a file (with the ability to read this QByteArray back from the file and into a QPixmap). I want to use following code from the QPixmap documentation: QPixmap pixmap(<image path>); QByteArray bytes; QBuffer buffer(&bytes); buffer.open(QIODevice::WriteOnly); pixmap.save(&buffer, "PNG"); // writes pixmap into bytes in PNG format After writing the buffer to a file, I want to be able to retrieve the QByteArray and load it back into a QPixmap using the QPixmap::loadFromData() function. Please let me know if any further clarification is needed (I'm open to alternative approaches as well, I just need to be able to read and write the QPixmap to a file! :) );

• Dynamic path in new.AjaxRequest with Rails

  - by Robbie

  Hello, I was wondering if there's anyway to get a 'dynamic path' into a .js file through Ruby on Rails. For example, I have the following: new Ajax.Request('/tokens/destroy/' + GRID_ID, {asynchronous:true, evalScripts:true, onComplete:function(request){load('26', 'table1', request.responseText)}, parameters:'token=' + dsrc.id + '&authenticity_token=' + encodeURIComponent(AUTH_TOKEN)}) The main URL is '/tokens/destroy/:id', however on my production server this app runs as a sub folder. So the URL for this ajax call needs to be '/qrpsdrail/tokens/destroy/:id' The URL this is being called from would be /grids/1 or /qrpsdrail/grids/1 I could, of course, do ../../path -- but that seems a bit hackish. It is also dependent on the routing never changing, which at this stage I can't guarantee. I'm just interested in seeing what other solutions there might be to this problem. Thanks in advance :)

• Pre-cache site as user visits

  - by strager

  I am making a static site which is 'forced' to be cached via Cache-control, etc. When a user visits my site, I want the browser to crawl my site, caching pages, so when the user navigates to a page, the load is almost instant. (I do not need a recursive crawl, as that will probably happen as the user navigates between pages. I just need to crawl the links on the current page, and of course not re-caching a page which has already been cached.) (Also, I am not changing pages using Ajax-like techniques. These are essentially normal flat HTML files with normal links.) How can I do this pre-caching using Javascript? (I am using jQuery.)

• x86 Assembly - printf doesn't print without "\n"

  - by Bitani

  So I'm confused. I'm going through the book "Programming from the Ground Up" and am working with using libraries. printf is working just fine so long as I include a "\n" in the string, but without it it will print absolutely nothing. Any idea why this happens? Code: .section .data my_str: .ascii "Jimmy Joe is %d years old!\n\0" my_num: .long 76 .section .text .globl _start _start: pushl my_num pushl $my_str call printf movl $1, %eax movl $0, %ebx int $0x80 Also, when I use -m elf_i386 for 32-bit mode and -dynamic-linker /lib/ld-linux.so.2 -lc to link, I get the warning ld: skipping incompatible /usr/lib64/libc.so when searching for -lc If that makes any difference, or if anybody has any suggestions as to how to have it load the 32-bit library directly. Thanks!
