  • Web scraping: how to get scraper implementation from text link?

    - by isme
    I'm building a java web media-scraping application for extracting content from a variety of popular websites: youtube, facebook, rapidshare, and so on. The application will include a search capability to find content urls, but should also allow the user to paste a url into the application if they already where the media is. Youtube Downloader already does this for a variety of video sites. When the program is supplied with a URL, it decides which kind of scraper to use to get the content; for example, a youtube watch link returns a YoutubeScraper, a Facebook fanpage link returns a FacebookScraper and so on. Should I use the factory pattern to do this? My idea is that the factory has one public method. It takes a String argument representing a link, and returns a suitable implementation of the Scraper interface. I guess the Factory would hold a list of Scraper implementations, and would match the link against each Scraper until it finds a suitable one. If there is no suitable one, it throws an Exception instead.

  • Does MS Access 2010 have Tif image control display issue?

    - by ChuckB
    We run MS Access as the front end for most of our business. When we upgraded from Access 2000 to Access 2003 the image control we used to print out Tif images failed to load Tifs anymore. A bit of Googling showed that MS did this intentionally and I'm wondering if the problem still happens in Access 2010. Can someone with a downloaded copy drop an image control on an Access 2010 form or report and try to get it to display a Tif file?

  • Using vertical-align on an element with background-image

    - by bobo
    <style type='text/css'> #span1{ background-image:url("http://www.reoiv.com/images/rss.jpg"); background-repeat:no-repeat; cursor:pointer; display:block; float:left; height:15px; width:15px; vertical-align:text-bottom; } </style> <span id='span1'></span>???? What I would like to do is to achieve the vertical align: text-bottom effect but I am not doing it on a image element. I am doing it on an element with background-image set. If you paste the above codes here: http://htmledit.squarefree.com/ You will see that the text failed to vertically align to bottom. I would like to know how it can be done without adding extra html element if possible. Many thanks to you all.

  • What should be the ideal number of parallel java threads for copying a large set of files from a qua

    - by ukgenie
    What should be the ideal number of parallel java threads for copying a large set of files from a quad core linux box to an external shared folder? I can see that with a single thread it is taking a hell lot of time to move the files one by one. Multiple threads is improving the copy performance, but I don't know what should be the exact number of threads. I am using Java executor service to create the thread pool.

  • How to build Lucene / Solr from source code in windows environment in order to add patches

    - by Simon
    I have successfully implemented Apache’s Solr for free text searching a database driven web site build for windows platforms using Visual Studio in c#. I am trying to get a version Solr working with field collapsing (which is not in the release version). There are patches available from apache and discussions on the web of people successfully doing this for the version I am using but my problem is cannot get the build to work. I am a c# coder on windows platforms so java development is new to me. I understand I need to get the correct source code (and revision) from SVN, add the appropriate patches, then build the war file to deploy to my system. I cannot seem to get the source to build and produce the deployment code including jar (and subsequent war) files. My system is: Windows 7 Ultimate for development Visual Studio 2010 for c# / javascript development MyEclipse 8.6 / Eclipse 3.5 for the java build from source Subecplise 1.6x SVN plugin to get the source from apache’s SVN Apache Solr 1.4.1 So far I have: Found the right patches for the function I need: https://issues.apache.org/jira/browse/SOLR-236 Specifically I need to patch: field_collapsing_1.1.0.patch HTTPS //issues.apache.org/jira/secure/attachment/12357681/field_collapsing_1.1.0.patch and SOLR-236-1_4_1.patch HTTPS //issues.apache.org/jira/secure/attachment/12448216/SOLR-236-1_4_1.patch I downloaded the Lucene trunk version from the day before the patch was released (revision 958303 from 28/6/10) via subeclipse into a java package in myeclipse from: HTTPS //svn.apache.org/repos/asf/lucene/dev/trunk (Solr is the web implementation of Lucene and is in the subfolder solr/) I can apply patches to the solr directory once it has downloaded but the parent Lucene project doesn’t build the war files, copy the jar or other files into the bin folder (it stays empty). The build process starts, but doesn’t do anything apart from creating the folders bin and src. I am building the whole Lucene project, which contains Solr. I have tried building the source without patching and the same happens. If I copy out the Solr directory into a new project, it runs the build and copies all the related files, tests, etc but fails with 4,500 errors and does not produce the jar files or war file, which I assume is because it can’t find the Lucene trunk files which it depends on. I have two interrelated problems 1) I can't get the Lucene downloaded trunk to build 2) The jar, war and associated files are not created Can anyone help with what I am missing to build the war file? I have spent 2 days to get this far as the help online is extremely patchy and I can’t find a walk though tutorial on building a java war file from source in a windows environment. Any help will be much appreciated. Simon

  • Drupal - no self-linking

    - by pygorex1
    So, I've added several pages to my Drupal install and linking to the pages using URL aliases via the Path module. So far so good - http://mydrupal/node/1 becomes http://mydrupal/about which is exactly what I'm looking for. Then I'm adding these links to the primary navigation and outputting the primary links via a custom theme (copy and paste the primary link code from the Chameleon theme). Here's the problem: when viewing http://mydrupal/about the page links to itself - that is the "About" link at http://mydrupal/about is still linking to http://mydrupal/about - the behavior I'm looking for is to have the "About" text display without a link. In summary: how do I prevent self-linking of pages when displaying the primary navigation?

  • Remove identical files in UNIX

    - by Thrawn
    Hi all, I'm dealing with a large amount (30,000) files of about 10MB in size. Some of them (I estimate 2%) are actually duplicated, and I need to keep only a copy for every duplicated pair (or triplet). Would you suggest me an efficient way to do that? I'm working on unix. Thank you :-)

  • Windows Constants for Ctrl+X, Ctrl+C, and Ctrl+V

    - by Jonathan Wood
    I've got some older MFC code I wrote that I'm "freshening up" a bit. I have the following code in a window class' OnChar() handler. I really don't like using constants like 0x18. I'd like to make the code more readable. I know I can declare my own, but are there no Windows macros for these values? I couldn't find anything about this on the web. // Check for clipboard commands switch (nChar) { case 0x18: // Ctrl+X - Cut OnEditCut(); break; case 0x03: // Ctrl+C - Copy OnEditCopy(); break; case 0x16: // Ctrl+V - Paste OnEditPaste(); break; }

  • Question about migrating from ASP .NET User Controls to .NET 3.5 Master Page technology

    - by Jim McFetridge
    When migrating from an ASP .NET user control -based page with a header, footer, and menu to a Master Page using the same HTML mark-up, is it normal for CSS or javascript behaviors to change slightly? In particular, the submenu bar text now appears run together (which looks like a CSS symptom) and the graphics on the line above it appear to have an incorrect z-order. (The menu operation is javascript-based.) (I tried to paste images here but couldn't.) Also, the site is very large and we've not been given permission to redo the menu for the entire site. This is a forward-only migration. (Because I know that someone will ask.) Assuming that there are no changes in scope, what are the things that I should check? Thanks! Jim

  • Redirect Output of Capistrano

    - by Eric Lubow
    I have a Capistrano deploy file (Capfile) that is rather large, contains a few namespaces and generally has a lot of information already in it. My ultimate goal is, using the Tinder gem, paste the output of the entire deployment into Campfire. I have Tinder setup properly already. I looked into using the Capistrano capture method, but that only works for the first host. Additionally that would be a lot of work to go through and add something like: output << capture 'foocommand' Specifically, I am looking to capture the output of any deployment from that file into a variable (in addition to putting it to STDOUT so I can see it), then pass that output in the variable into a function called notify_campfire. Since the notify_campfire function is getting called at the end of a task (every task regardless of the namespace), it should have the task name available to it and the output (which is stored in that output variable). Any thoughts on how to accomplish this would be greatly appreciated.

  • Coldfusion Report Builder - How can you set different datasources externally between prod/staging/de

    - by Smooth Operator
    Coldfusion Report Builder is great. One small issue. We use ANT+CFANT to deploy. When we create the report, say in a datasource called MyApp_dev on a dev box. Everything works great when the report is created. We deploy the report to our staging server, which has a datasource of MyApp_Staging. That server also, may or may not, have the live app working under MyApp_Live. Ant pushes the update to Staging just great. Run the report, crashes and burns. Why? It seems the report is looking for the MyApp_Dev data_source, even though the application is using the MyApp_Staging datasource. In digging around I found a few approaches, I would like to do this one, final, ideal way from the beginning instead of having to go back to do dozens of reports differently when I have a new Aha! moment. 1) Obvious: Pass in the datasource in to the cfreport tag. Doesn't work for ColdFusion Builder Reports as of v8, or v9 as tested on Linux. 2) Most realistic option (but painful) so far: Pass in the query as an object into the ColdFusion Builder report. Let's think about this: Create the Report with the report builder to my heart's content using the RDS, etc on my local box. When I'm done, copy the query into a snippet of code, or into a database column to be dynamically be injected at runtime with correct datasource. Modify my "run report" event to find the query from the database column, insert it into another dynamic cfquery and potentially... evaluate (!?!) it? Fun side is I can set the cfquery datasource to what I would need for each environment. When I modify the report's columns in CF Report Builder, I always have to update the query in the database. Is there a snippet of code that can extract this for me? Hmm. 3) Less than ideal. Suck it up and let all the reports in staging run off the live server. Maybe copy the live data into staging (sans structural changes) to let it seem similar. Are there any eloquent ways to accomplish the above? Thanks in Advance!

  • javascript textbox call event when value changes

    - by Senica Gonzalez
    I have a textbox, and whenever the value of the box changes, I want to check and see if 20 digits have been entered. I thought that I would use the onChange event, but this seems to be interpreted as the onBlur event on IE. So then I thought I would use onKeyDown, but the problem comes in if the user wants to paste a value into the field, then the function never gets called. There are no other form boxes so I can't rely on onBlur or expect that they will change focus ever. How do I do this? I just want to evaluate the value of the textbox everytime the value of the textbox changes. <input type="text" onKeyDown="myfunction()">

  • Adding images to version control with Subclipse

    - by Brian
    Hello, I know that when using Subversion, adding/copying/renaming files must be done via 'svn add' or 'svn copy' etc. In my Eclipse IDE, I use Subclipse to work with subversion. It's easy enough to add text-based files to version control (ie. php/html/js files) - but how do I properly add images to version control using Subclipse? Thanks, Brian

  • Debugging SQL in PGAdmin3 when sql contains variables

    - by Mr Shoubs
    In SQL Server I could copy sql code out of an application and paste it into SSMS, declare & assign vars that exist in the sql and run.. yay great debugging scenario. e.g. (please note I am rust and syntax may be incorrect) declare @x as varchar(10) set @x = 'abc' select * from sometable where somefield = @x I want to do something simular with postgres in pgadmin3 (or another postgres tool, anyy reccomendations?) I realise you can create pgscript, but it doesn't appear to be very good, for example, if I do the equlivent of above, it doesn't put the single quotes around the value in @x, nor does it let me by doubling them up and you don't get a table out after - only text... Currently I have a peice of sql someone has written that has 3 unique varibles in it which are used around 6 times each... So the question is how do other people debug sql this sql EFFICIENTLY, preferably in a simular fashion to my sql server days.

  • Python: How efficient is subtring extraction?

    - by Cameron
    I've got the entire contents of a text file (at least a few KB) in string myStr. Will the following code create a copy of the string (less the first character) in memory? myStr = myStr[1:] I'm hoping it just refers to a different location in the same internal buffer. If not, is there a more efficient way to do this? Thanks!
