  • Why do I get "undefined method `destroy'" when including 'svn/repos'?

    I get the following when running script/server require 'svn/repos' script/console Loading development environment (Rails 2.3.5) require 'svn/repos' /Library/Ruby/Site/1.8/svn/core.rb:88: warning: already initialized constant Stream /Library/Ruby/Site/1.8/svn/core.rb:138: warning: already initialized constant AuthBaton NoMethodError: undefined method destroy' for #<Svn::Ext::Core::Apr_pool_wrapper_t:0x10150ae68> from /Library/Ruby/Site/1.8/svn/util.rb:60:insvn_fs_initialize' from /Library/Ruby/Site/1.8/svn/util.rb:60:in call' from /Library/Ruby/Site/1.8/svn/util.rb:60:ininitialize' from /Library/Ruby/Site/1.8/svn/fs.rb:14 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in gem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:inrequire' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in require' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:innew_constants_in' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in require' from /Library/Ruby/Site/1.8/svn/repos.rb:5 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:ingem_original_require' from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in require' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:inrequire' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in new_constants_in' from /Library/Ruby/Gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:inrequire' from (irb):1 Any idea why?

  • Regular Expression for any number divisible by 60 using C# .Net ?

    - by Steve Johnson
    Hi there, I need to apply validation on input time intervals that are taken in as seconds. Now i am not really good at Regular expressions. So can any body help making a regular expression that can test whether a number is divisible by 60. I was wondering if i could use to test one that check that the number is divisible by 10 and then check whether the same is divisible by 6. For number divisible by 10 here [\d*0] is the expression i guess. Please correct me if i am wrong. Hope somebody solves my problem. Thanks

  • Oracle SQL clause evaluation order

    - by jon.johnson
    In Oracle, which clause types get evaluated first? If I had the following ( pretend .... represent valid expressions and relation names ), what would the order of evaluation be? SELECT ... FROM ..... WHERE ........ GROUP BY ........... HAVING ............. ORDER BY ................ I am under the impression that the SELECT clause is evaluated last, but other than that I'm clueless.

  • Rails initializes extremely slow on ruby 1.9.1

    - by Ben Johnson
    I just got my rails 2.3.8 app running on ruby 1.9.1. To get into the console, start the webserver, anything that initializes rails, takes 3 - 4 times longer in ruby 1.9 than in ruby 1.8.7. I'm using ruby version managers so I can easily switch between ruby 1.9 and ruby 1.8.7. The speed difference happens in both production and development. I want to use 1.9 because its must faster once everything is running, but the startup time is so bad the app is timing out on Heroku on the first request. Any ideas why ruby 1.9 would be 3 - 4 times slower? I can't figure it out for the life of me.

  • I'm using a sequence in Factory Girl to get unique values but I'm getting validation errors

  • MySQL index cardinality - performance vs storage efficiency

    - by Sean
    Say you have a MySQL 5.0 MyISAM table with 100 million rows, with one index (other than primary key) on two integer columns. From my admittedly poor understanding of B-tree structure, I believe that a lower cardinality means the storage efficiency of the index is better, because there are less parent nodes. Whereas a higher cardinality means less efficient storage, but faster read performance, because it has to navigate through less branches to get to whatever data it is looking for to narrow down the rows for the query. (Note - by "low" vs "high", I don't mean e.g. 1 million vs 99 million for a 100 million row table. I mean more like 90 million vs 95 million) Is my understanding correct? Related question - How does cardinality affect write performance?

  • Get the date of a given day in a given week...

    - by Sean.C
    i need to start at a year-month and work out what the date it is in a given week, on a given day within that week.. i.e year: 2009 month: 10 week: 5 day-number: 0 would return 2009-10-25 00:00:00 which is a sunday. Notice week 5, there is no day 0 in week 5 in 2009-10 as the sunday in that logical week is 2009-11-01 00:00:00... so week 5 would always return the last possible date for the given day in the given month.. if you havn't guessed already i'm messing with the c struct TIME_ZONE_INFORMATION (link text) which is pretty crazy if i'm fair... Date math and SQL are something to be admired, sadly its something i have never really dug deep into beyond stripping times. Any help would be greatly appriciated. PS: mssql 2005 btw..

  • Invalid iPhone Application Binary

    - by Kristopher Johnson
    I'm trying to upload an application to the iPhone App Store, but I get this error message from iTunes Connect: The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate. My guess is that it is not properly signed. I have downloaded my App Store distribution certficate, but I can't figure out how to "sign" my application with it. The SDK's documentation about code signing is not very helpful. (FWIW, I can install the app on my iPhone just fine using the development provisioning profile.) However, it is possible that I screwed things up on a more basic level. Here's what I did to try to prepare it for upload: In Xcode, select the Device|Release target Select the target and click the Info button. Change "Code Signing Identity" to "iPhone Distribution", and change "Code Signing Provisioning Profile" to my App Store distribution profile. Build Go to the directory where the built MyApp.app bundle is, control-click and choose "Compress" to create MyApp.zip Upload MyApp.zip to the App Store via iTunes Connect (which resulted in the above error message). Can anybody give me any hints? Edit: Found someone with the same problem. Unfortunately, he won't tell us how he fixed it. http://www.rhonabwy.com/wp/2008/07/18/seattlebus-diary-ongoing-update-saga/#comments http://www.rhonabwy.com/wp/2008/07/22/seattlebus-diary-update-is-pending-review/ (Note: For general information on submitting iPhone applications to the App Store, see Steps to upload an iPhone application to the AppStore.)

  • Help me convert this PHP SOAP code to C#

    - by Andrew G. Johnson
    Hi, I am trying to do some C# SOAP calls and can't seem to get any good examples on how to do it. I read an old question of mine about a SOAP call in PHP and thought maybe asking you guys to rewrite it in C# would be a good place to start. Here is the PHP code: $client = new SoapClient('http://www.hotelscombined.com/api/LiveRates.asmx?WSDL'); $client->__soapCall('HotelSearch', array( array('request' => array( 'ApiKey' => 'THE_API_KEY_GOES_HERE', // note that in the actual code I put the API key in... 'UserID' => session_id(), 'UserAgent' => $_SERVER['HTTP_USER_AGENT'], 'UserIPAddress' => $_SERVER['REMOTE_ADDR'], 'HotelID' => '50563', 'Checkin' => '07/02/2009', 'Checkout' => '07/03/2009', 'Guests' => '2', 'Rooms' => '1', 'LanguageCode' => 'en', 'DisplayCurrency' => 'usd', 'TimeOutInSeconds' => '90' ) ) ) );

  • How does Facebook chat avoid continuous polling of the server?

    - by Chad Johnson
    I am trying to understand how Facebook's chat feature receives messages without continuously poling the server. Firebug shows me a single GET XmlHttpRequest continuously sitting there, waiting for a response from the server. After 5 minutes, this never timed out. How are they preventing timeout? An AJAX request can just sit there like that indefinitely, waiting for a response? Can I do this with JSONRequest? I see this at json.org: JSONRequest is designed to support duplex connections. This permits applications in which the server can asynchronously initiate transmissions. This is done by using two simultaneous requests: one to send and the other to receive. By using the timeout parameter, a POST request can be left pending until the server determines that it has timely data to send. Or is there another way to let an AJAX call just sit there, waiting, besides using JSONRequest?

  • Application Context in Rails

    - by Sean McMains
    Rails comes with a handy session hash into which we can cram stuff to our heart's content. I would, however, like something like ASP's application context, which instead of sharing data only within a single session, will share it with all sessions in the same application. I'm writing a simple dashboard app, and would like to pull data every 5 minutes, rather than every 5 minutes for each session. I could, of course, store the cache update times in a database, but so far haven't needed to set up a database for this app, and would love to avoid that dependency if possible. So, is there any way to get (or simulate) this sort of thing? If there's no way to do it without a database, is there any kind of "fake" database engine that comes with Rails, runs in memory, but doesn't bother persisting data between restarts?

  • How to use bundler gem binaries in path

    - by Sean Chambers
    I just started using bundler for gem packaging in vendor/. The problem is with certain gems (like rspec and cucumber) that have binaries. The binary path that is under my_app/vendor/gems/ruby/1.8/...cucumber-0.6.2/bin/ is not in my path, therefore when I go to run cucumber i get command cannot be found. What is the easiest way to execute the bundled gem binaries from within the app rather than adding a large number of folders to my path? Thanks

  • JButton Layout Issue

  • How to access a PHP Web Service from ASP.Net?

  • Emulating a web browser

    - by Sean
    Hello, we are tasked with basically emulating a browser to fetch webpages, looking to automate tests on different web pages. This will be used for (ideally) console-ish applications that run in the background and generate reports. We tried going with .NET and the WatiN library, but it was built on a Marshalled IE, and so it lacked many features that we hacked in with calls to unmanaged native code, but at the end of the day IE is not thread safe nor process safe, and many of the needed features could only be implemented by changing registry values and it was just terribly unflexible. Proxy support JavaScript support- we have to be able to parse the actual DOM after any javascript has executed (and hopefully an event is raised to handle any ajax calls) Ability to save entire contents of page including images FROM THE loaded page's CACHE to a separate location ability to clear cookies/cache, get the cookies/cache, etc. Ability to set headers and alter post data for any browser call And for the love of drogs, an API that isn't completely cryptic Languages acceptable C++, C#, Python, anything that can be a simple little console application that doesn't have a retarded syntax like Ruby. From my own research, and believe me I am terrible at google searches, I have heard good things about WebKit... would the Qt module QtWebKit handle all these features?

  • mysql - select pagination chunk that includes a given id

    - by sean smith
    ...before the pagination chunks have been determined. I know you can do this in multiple statements, but there must be a better way. my results are returned ordered by date and I want to return the pagination chunk that contains a given id. So I could, for example, select the date of the given id and then select a chunk of results where date is less than or greater than the date. That would work. But is there some native mysql method of doing this sort of thing in one statement? It just seems reasonable to expect that we could ask for X results in which a given id exists if results are ordered by date.

  • map xml element to xsd complexType based on attribute

    - by Joshua Johnson
    Assume there exists an XML instance document that looks like this: <root> <object type="foo"> <!-- ... --> </object> <object type="bar"> <!-- ... --> </object> </root> My goal is to have a small (static) schema that verifies proper <element type="xxx" /> syntax for objects, and another schema (more prone to change) that verifies the contents of each object element against a complexType that matches the type attribute: <complexType name="foo"><!--should match object with type="foo"--></complexType> <complexType name="bar"><!--should match object with type="bar"--></complexType> What is the best way to accomplish this (or something similar)?

  • SSD and programming

    - by Simon Johnson
    I'm trying to put together a business case for getting every developer in our company an Intel SSD drive. The main codebase contains roughly 400,000 lines of code. My theory is that since the code is scattered about in maybe 1500 files, an SSD drive would be substantially faster for compiles. The logic being that many small reads really punishes the seak-time bottle-neck of a traditional hard-drive. Am I right? Is SSD worth the money in productivity gains by reducing the edit/compile cycle time?

  • Using perl to parse a file and insert specific values into a database

    - by Sean
    Disclaimer: I'm a newbie at scripting in perl, this is partially a learning exercise (but still a project for work). Also, I have a much stronger grasp on shell scripting, so my examples will likely be formatted in that mindset (but I would like to create them in perl). Sorry in advance for my verbosity, I want to make sure I am at least marginally clear in getting my point across I have a text file (a reference guide) that is a Word document converted to text then swapped from Windows to UNIX format in Notepad++. The file is uniform in that each section of the file had the same fields/formatting/tables. What I have planned to do, in a basic way is grab each section, keyed by unique batch job names and place all of the values into a database (or maybe just an excel file) so all the fields can be searched/edited for each job much easier than in the word file and possibly create a web interface later on. So what I want to do is grab each section by doing something like: sed -n '/job_name_1_regex/,/job_name_2_regex/' file.txt --how would this be formatted within a perl script? (grab the section in total, then break it down further from there) To read the file in the script I have open FORMAT_FILE, 'test_format.txt'; and then use foreach $line (<FORMAT_FILE>) to parse the file line by line. --is there a better way? My next problem is that since I converted from a word doc with tables, which looks like: Table Heading 1 Table Heading 2 Heading 1/Value 1 Heading 2/Value 1 Heading 1/Value 2 Heading 2/Value 2 but the text file it looks like: Table Heading 1 Table Heading 2Heading 1/Value 1Heading 1/Value 2Heading 2/Value 1Heading 2/Value 2 So I want to have "Heading 1" and "Heading 2" as a columns name and then put the respective values there. I just am not sure how to get the values in relation to the heading from the text file. The values of Heading 1 will always be the line number of Heading 1 plus 2 (Heading 1, Heading 2, Values for heading 1). I know this can be done in awk/sed pretty easily, just not sure how to address it inside a perl script. After I have all the right values and such, linking it up to a database may be an issue as well, I haven't started looking at the way perl interacts with DBs yet. Sorry if this is a bit scatterbrained...it's still not fully formed in my head.
