  • Download HTML and Images with WGet without first few lines

    - by St. John Johnson
    I'm attempting to use wget with the -p option to download specific documents and the images linked in the HTML. The problem is, the site that is hosting the HTML has some non-html information preceding the HTML. This is causing wget to not interpret the document as HTML and doesn't search for images. Is there a way to have wget strip the first X lines and/or force searching for images? Example URL: http://www.sec.gov/Archives/edgar/data/13239/000119312510070346/ds4.htm First Lines of Content: <DOCUMENT> <TYPE>S-4 <SEQUENCE>1 <FILENAME>ds4.htm <DESCRIPTION>FORM S-4 <TEXT> <HTML><HEAD> <TITLE>Form S-4</TITLE> Last Lines of Content: </BODY></HTML> </TEXT> </DOCUMENT>

  • Insert into a star-schema

    - by shaun
    I've read a lot about star-schema's, about fact/deminsion tables, select statements to quickly report data, however the matter of data entry into a star-schema seems aloof to me. How does one "theoretically" enter data into a star-schema db? while maintaining the fact table. Is a series of INSERT INTO statement within giant stored proc with 20 params my only option (and how to populate the fact table). Many thanks.

  • Setup Padrino with DataMapper and MySQL database

    - by Ivo Sabev
    Hello I am trying to setup a Padrino project using DataMapper and MySQL on my Mac OSX Snow Leopard. I have the necessary gems: dm-core data_objects do_mysql mysql (linked to my original Mac OSX installation) But when I try to start the padrino with PADRINO START from the console, I get the following error: /Users/ivolution/.bundle/ruby/1.9.1/gems/dm-core-0.10.2/lib/dm-core/adapters/mysql_adapter.rb:3:in `require': no such file to load -- do_mysql (LoadError) But as I said I do have do_mysql gem installed so there shouldn't be such error, I did bundle install in my project folder before trying to start Padrino. Any ideas?

  • Graphing new users by date in a Rails app using Seer

    - by Danger Angell
    I'd like to implement a rolling graph showing new users by day over the last 7 days using Seer. I've got Seer installed: http://www.idolhands.com/ruby-on-rails/gems-plugins-and-engines/graphing-for-ruby-on-rails-with-seer I'm struggling to get my brain around how to implement. I've got an array of the Users I want to plot: @users = User.all( :conditions = {:created_at = 7.days.ago..Time.zone.now}) Can't see the right way to implement the :data_method to roll them up by created_at date. Anyone done this or similar with Seer? Anyone smarter than me able to explain this after looking at the Seer sample page (linked above)?

  • Drupal node_save and special characters.

    - by Pierre
    Hello, i'm trying to create nodes and taxonomy terms through a custom php script by using the node_save() function. I'm working on drupal 6. It's working well (thanks to previous questions on stackoverflow) except for accented letters. Indeed, when a title or a taxonomy term contain "é", "è" or "à", the sentence is cut before those special characters. For example, a title like that: "Bonjour les éléphants" will create a node with "Bonjour les " as title. I don't know if it's linked to my database or if i have to use a special encoding in php (iconv() blabla) The fact is, for drupal titles, i can not use html encoding (for example: é is é in html) because drupal will render &eacute and not é... When i create a taxonomy or a title manually, i have no problems and the accented letter is saved in the database as "é". Soo if you can help me to create terms and title with accented letters, that will be great : ) Thank you !

  • How to speed up calculation of length of longest common substring?

    - by eSKay
    I have two very large strings and I am trying to find out their Longest Common Substring. One way is using suffix trees (supposed to have a very good complexity, though a complex implementation), and the another is the dynamic programming method (both are mentioned on the Wikipedia page linked above). Using dynamic programming The problem is that the dynamic programming method has a huge running time (complexity is O(n*m), where n and m are lengths of the two strings). What I want to know (before jumping to implement suffix trees): Is it possible to speed up the algorithm if I only want to know the length of the common substring (and not the common substring itself)?

  • Storing Objects in columns using Hibernate JPA

    - by user210791
    Is it possible to store something like the following using only one table? Right now, what hibernate will do is create two tables, one for Families and one for people. I would like for the familymembers object to be serialized into the column in the database. @Entity(name = "family") class Family{ private final List<Person> familyMembers; } class Person{ String firstName, lastName; int age; }

  • Automatic incremental SQL Script generation for incremental, nightly builds when using Team Build in

    - by Steve Johnson
    hi all, hope that everybody here is OK. We are using VS 2008 as development tool, TFS 2008 as version control as well as build automation. Some of our developer use dbpro for databases changes and some use SQL Server management studio. I am trying to automate build for Web Application built using C# and VB.Net. Our scenario is such that we have a central database to which our web application connects. Whenever we supply our clients with a new functionality or a bug fix, we supply them incremental builds. The SQL script is checked into source control for every incremental build when they have made and tested there changes on our central DB Server. I want to generate Differential script that can be run at the client as an incremental update script. Now to come about it is a problem. Sometimes our developers tend to forget the database change-sets and the script in the source control is missing an SP or a two. Also, sometimes we need to insert default data into some of the tables that have strict stringent values and not test values. Like a table that contains Services provided by the panel, we add a new service name, signature, credentials and service address, etc etc in the ServiceTable. Besides this many other tables may have test data that may not be needed. If we use DataCompare, it will generate changeset for required data (important for client to enable certain services) and our test data that was added to the database as a result of our testing of the functionality or bug fix. Currently i am using SQLSchemaCompareTask (from Visual Studio 2008 Team Database Professional Power Tools API) in the TFSBuild.proj file of the build definition for TFS 2008. Using SQLSchemaCompareTask, the script generated contains database names like [dbo]. etc which are not desired as the script fails when run against SQL Server 2000 databses (Some of our client still use SQL Server 2000) databases as teh backend of the application. Also default data can't be generated by this process. To overcome this problem, i have to come up with a solution that can compare databases and generate script automatically that does not have to be manually reviewed again before being sent to the client. Please suggest effective methodology of such SQL script generation and suggest whether two different databases may be used or something ? Is there any toolkit or api that can enable build automation for SQL Server databases? Thank you all. Regards Steve

  • DataTable identity column not set after DataAdapter.Update/Refresh on table with "instead of"-trigge

    - by Arno
    Within our unit tests we use plain ADO.NET (DataTable, DataAdapter) for preparing the database resp. checking the results, while the tested components themselves run under NHibernate 2.1. .NET version is 3.5, SqlServer version is 2005. The database tables have identity columns as primary keys. Some tables apply instead-of-insert/update triggers (this is due to backward compatibility, nothing I can change). The triggers generally work like this: create trigger dbo.emp_insert on dbo.emp instead of insert as begin set nocount on insert into emp ... select @@identity end The insert statement issued by the ADO.NET DataAdapter (generated on-the-fly by a thin ADO.NET wrapper) tries to retrieve the identity value back into the DataRow: exec sp_executesql N' insert into emp (...) values (...); select id, ... from emp where id = @@identity ' But the DataRow's id-Column is still 0. When I remove the trigger temporarily, it works fine - the id-Column then holds the identity value set by the database. NHibernate on the other hand uses this kind of insert statement: exec sp_executesql N' insert into emp (...) values (...); select scope_identity() ' This works, the NHibernate POCO has its id property correctly set right after flushing. Which seems a little bit counter-intuitive to me, as I expected the trigger to run in a different scope, hence @@identity should be a better fit than scope_identity(). So I thought no problem, I will apply scope_identity() instead of @@identity under ADO.NET as well. But this has no effect, the DataRow value is still not updated accordingly. And now for the best part: When I copy and paste those two statements from SqlServer profiler into a Management Studio query (that is including "exec sp_executesql"), and run them there, the results seem to be inverse! There the ADO.NET version works, and the NHibernate version doesn't (select scope_identity() returns null). I tried several times to verify, but to no avail. Of course this just shows the resultset coming from the database, whatever happens inside NHibernate and ADO.NET is another topic. Also, several session properties defined by T-SQL SET are different in the two scenarios (Management Studio query vs. application at runtime) This is a real puzzle to me. I would be happy about any insights on that. Thank you!

  • Removing table prefixes on ASP.NET MVC DataModel entities

    - by Tim Shults
    My database tables have prefixes on them and when the DataModel generates the EntityObjects they have the prefixes at the beginning of the class name. Is there anyway that I can have those prefixes ignored when the DataModel is updating/creating the classes? I've found the below question, but with no solution. http://stackoverflow.com/questions/1800065/removing-table-prefix-in-linq2sql-setup/2525827#2525827 Thanks in advance, Tim Shults

So database size will increase a lot but potencially the performance will grow up. Is that right? Is It possible? Thanks and sorry for my poor english

  • XSLT big integer (int64) handling msxml

    - by Farid Z
    When trying to do math on an big integer (int64) large number in xslt template I get the wrong result since there is no native 64-bit integer support in xslt (xslt number is 64-bit double). I am using msxml 6.0 on Windows XP SP3. Are there any work around for this on Windows? <tables> <table> <table_schem>REPADMIN</table_schem> <table_name>TEST_DESCEND_IDENTITY_BIGINT</table_name> <column> <col_name>COL1</col_name> <identity> <col_min_val>9223372036854775805</col_min_val> <col_max_val>9223372036854775805</col_max_val> <autoincrementvalue>9223372036854775807</autoincrementvalue> <autoincrementstart>9223372036854775807</autoincrementstart> <autoincrementinc>-1</autoincrementinc> </identity> </column> </table> </tables> This test returns true due to overflow (I am assuming) but actually is false if I could tell the xslt processor somehow to use int64 rather than the default 64-bit double for the data since big integer is the actual data type for the numbers in the xml input. <xsl:when test="autoincrementvalue = (col_min_val + autoincrementinc)"> <xsl:value-of select="''"/> </xsl:when> here is the complete template <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <!--Reseed Derby identity column--> <xsl:output omit-xml-declaration='yes' method='text' /> <xsl:param name="stmtsep">;</xsl:param> <xsl:param name="schemprefix"></xsl:param> <xsl:template match="tables"> <xsl:variable name="identitycount" select="count(table/column/identity)"></xsl:variable> <xsl:for-each select="table/column/identity"> <xsl:variable name="table_schem" select="../../table_schem"></xsl:variable> <xsl:variable name="table_name" select="../../table_name"></xsl:variable> <xsl:variable name="tablespec"> <xsl:if test="$schemprefix"> <xsl:value-of select="$table_schem"/>.</xsl:if><xsl:value-of select="$table_name"/></xsl:variable> <xsl:variable name="col_name" select="../col_name"></xsl:variable> <xsl:variable name="newstart"> <xsl:choose> <xsl:when test="autoincrementinc > 0"> <xsl:choose> <xsl:when test="col_max_val = '' and autoincrementvalue = autoincrementstart"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="col_max_val = ''"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:when test="autoincrementvalue = (col_max_val + autoincrementinc)"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="(col_max_val + autoincrementinc) &lt; autoincrementstart"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="col_max_val + autoincrementinc"/> </xsl:otherwise> </xsl:choose> </xsl:when> <xsl:when test="autoincrementinc &lt; 0"> <xsl:choose> <xsl:when test="col_min_val = '' and autoincrementvalue = autoincrementstart"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="col_min_val = ''"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:when test="autoincrementvalue = (col_min_val + autoincrementinc)"> <xsl:value-of select="''"/> </xsl:when> <xsl:when test="(col_min_val + autoincrementinc) > autoincrementstart"> <xsl:value-of select="autoincrementstart"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="col_min_val + autoincrementinc"/> </xsl:otherwise> </xsl:choose> </xsl:when> </xsl:choose> </xsl:variable> <xsl:if test="not(position()=1)"><xsl:text> </xsl:text></xsl:if> <xsl:choose> <!--restart with ddl changes both the next identity value AUTOINCREMENTVALUE and the identity start number AUTOINCREMENTSTART eventhough in this casewe only want to change only the next identity number--> <xsl:when test="$newstart != '' and $newstart != autoincrementvalue">alter table <xsl:value-of select="$tablespec"/> alter column <xsl:value-of select="$col_name"/> restart with <xsl:value-of select="$newstart"/><xsl:if test="$identitycount>1">;</xsl:if></xsl:when> <xsl:otherwise>-- reseed <xsl:value-of select="$tablespec"/> is not necessary</xsl:otherwise> </xsl:choose> </xsl:for-each> </xsl:template> </xsl:stylesheet>

  • Awstats showing 404s for pages and objects I definitely don't have...

    - by Andrew Heath
    I have a HostGator site using Awstats and I've recently noticed the following 3 bizarre 404s: [address] [times] /images/wikimedia-button.png 1 /apple-touch-icon.png 1 /imgs/custom-space.gif 1 the first and third also carry referrers from within my site, but are 100% definitely absolutely not linked by any of my pages. I'm not too worried about it, seeing as each one has only popped up once. But I am concerned about why Awstats thinks one of my pages is referring what is apparently a wikipedia image, and why Steve Jobs is trying to haxx0r me (/joke) This is my first site to receive moderate daily usage, so I'm curious if these sorts of unique weird-o 404s just come with the territory, or if I should be double-checking something... Thanks!
