  • Is there a list of known web crawlers?

    - by J. Pablo Fernández
    I'm trying to get accurate download numbers for some files on a web server. I look at the user agents and some are clearly bots or web crawlers, but many for many I'm not sure, they may or may not be a web crawler and they are causing many downloads so it's important for me to know. Is there somewhere a list of know web crawlers with some documentation like user agent, IPs, behavior, etc? I'm not interested in the official ones, like Google's, Yahoo's, or Microsoft's. Those are generally well behaved and self-indentified.

  • Problem with UTF-8

    - by Pablo Fernandez
    I'm using castor as an OXM mapper, and I'm having a problem with UTF-8 encoding. The code here shows the issue: //Marshaller configuration ByteArrayOutputStream baos = new ByteArrayOutputStream(); OutputStreamWriter os = new OutputStreamWriter(baos, UTF_8); Marshaller marshaller = new Marshaller(os); marshaller.setSuppressXSIType(true); //Mappings configuration Mapping map = new Mapping(); map.loadMapping(MarshallingService.class.getResource(MAPPINGS_PATH)); marshaller.setMapping(map); //Example //BEFORE MARSHALLING: This prints correctly the UTF-8 Chars object.getName() ; marshaller.marshal(object); //AFTER MARSHALLING: This returns the characters like \435\235\654\345 return baos.toString(UTF_8);

  • Thinking Sphinx not working in test mode

    - by J. Pablo Fernández
    I'm trying to get Thinking Sphinx to work in test mode in Rails. Basically this: ThinkingSphinx::Test.init ThinkingSphinx::Test.start freezes and never comes back. My test and devel configuration is the same for test and devel: dry_setting: &dry_setting adapter: mysql host: localhost encoding: utf8 username: rails password: blahblah development: <<: *dry_setting database: proj_devel socket: /tmp/mysql.sock # sphinx requires it test: <<: *dry_setting database: proj_test socket: /tmp/mysql.sock # sphinx requires it and sphinx.yml development: enable_star: 1 min_infix_len: 2 bin_path: /opt/local/bin test: enable_star: 1 min_infix_len: 2 bin_path: /opt/local/bin production: enable_star: 1 min_infix_len: 2 The generated config files, config/development.sphinx.conf and config/test.sphinx.conf only differ in database names, directories and similar things; nothing functional.

  • Capistrano, Mercurial and branches

    - by J. Pablo Fernández
    It is my understanding that although Mercurial has support from branches, the community generally clone repos instead of creating branches. Similar to the Darcs model, unlike the Git model. I'm deploying a Ruby on Rails app with Capistrano and there I'd like to separate the production from the development branch. Should I point Capistrano to a different repo or should I use branches?

  • How effective can this Tagging solution be?

    - by Pablo
    Im working on an image sharing site and want to implement tagging for the images. I've read Questions #20856 and #2504150 I have few concerns with the approach on the questions above. First of all it looks easy to link an image to a tag. However getting images by tag relation is not as easy. Not easy because you will have to get the image-to-tag relation from one table and then make a big query with a bunch of OR statements( one OR for every image). Before i even research the tagging topic i started testing the following method: This tables as examples: Table: Image Columns: ItemID, Title, Tags Table: Tag Columns: TagID, Name The Tags column in the Image table takes a string with multiple tagID from the Tag table enclosed by dashes(-). For example: -65-25-105- Links an image with the TagID 65,25 and 105. With this method i find it easier to get images by tag as i can get the TagID with one query and get all the images with another simple query like: SELECT * FROM Image WHERE Tags LIKE %-65-% So if i use this method for tagging, How effective this is? Is querying by LIKE %-65-% a slow process? What problems can i face in the future?

  • SQL Server: SELECT rows with MAX(Column A), MAX(Column B), DISTINCT by related columns

    - by z531
    Scenario: Table A MasterID, Added Date, Added By, Updated Date, Updated By, 1, 1/1/2010, 'Fred', null, null 2, 1/2/2010, 'Barney', 'Mr. Slate', 1/7/2010 3, 1/3/2010, 'Noname', null, null Table B MasterID, Added Date, Added By, Updated Date, Updated By, 1, 1/3/2010, 'Wilma', 'The Great Kazoo', 1/5/2010 2, 1/4/2010, 'Betty', 'Dino', 1/4/2010 Table C MasterID, Added Date, Added By, Updated Date, Updated By, 1, 1/5/2010, 'Pebbles', null, null 2, 1/6/2010, 'BamBam', null, null Table D MasterID, Added Date, Added By, Updated Date, Updated By, 1, 1/2/2010, 'Noname', null, null 3, 1/4/2010, 'Wilma', null, null I need to return the max added date and corresponding user, and max updated date and corresponding user for each distinct record when tables A,B,C&D are UNION'ed, i.e.: 1, 1/5/2010, 'Pebbles', 'The Great Kazoo', 1/5/2010 2, 1/6/2010, 'BamBam', 'Mr. Slate', 1/7/2010 3, 1/4/2010, 'Wilma', null, null I know how to do this with one date/user per row, but with two is beyond me. DBMS is SQL Server 2005. T-SQL solution preferred. Thanks in advance, Dave

  • Call private methods and private properties from outside a class in PHP

    - by Pablo López Torres
    I want to access private methods and variables from outside the classes in very rare specific cases. I've seen that this is not be possible although introspection is used. The specific case is the next one: I would like to have something like this: class Console { final public static function run() { while (TRUE != FALSE) { echo "\n> "; $command = trim(fgets(STDIN)); switch ($command) { case 'exit': case 'q': case 'quit': echo "OK+\n"; return; default: ob_start(); eval($command); $out = ob_get_contents(); ob_end_clean(); print("Command: $command"); print("Output:\n$out"); break; } } } } This method should be able to be injected in the code like this: Class Demo { private $a; final public function myMethod() { // some code Console::run(); // some other code } final public function myPublicMethod() { return "I can run through eval()"; } private function myPrivateMethod() { return "I cannot run through eval()"; } } (this is just one simplification. the real one goes through a socket, and implement a bunch of more things...) So... If you instantiate the class Demo and you call $demo-myMethod(), you'll get a console: that console can access the first method writing a command like: > $this->myPublicMethod(); But you cannot run successfully the second one: > $this->myPrivateMethod(); Do any of you have any idea, or if there is any library for PHP that allows you to do this? Thanks a lot!

  • Rails 2 support after Rails 3 has been released

    - by J. Pablo Fernández
    Is there some plan or estimate about how long will Rails 2 be supported after Rails 3 has been released? I wanted to ride the wave and move to Rails 3 right away, specially for projects that may take 4 or 6 months to finish (so that they would probably be released with Rails 3.0.0 final) but I've found many things still not working, many basic plugins and gems; so I believe I'm stuck with Rails 2 for now.

  • How to pause a setTimeout call ?

    - by Pablo
    Im using jQuery and working on a notification system for my site. The notifications automatically fadeout using the setTimeout function. How can i stop the timer of the setTimeout call? For example i would like to pause the setTimeout call while the mouse is over the notification and continue the count down mouseout... I googled "pause setTimeout" with no luck. Im currently clearing the setTimeout call with clearTimeout and at same time fading out the notification on mouseout but it would be nice to have that pause effect. Any ideas?

  • How to register a service with Mono.ZeroConf?

    - by pablo
    Hi, I'm trying to test the ZeroConf sample at http://www.mono-project.com/Mono.Zeroconf. I'm running OpenSuse 11 and Mono 2.2. My server code is: using System; using Mono.Zeroconf; namespace zeroconftestserver { class MainClass { public static void Main(string[] args) { RegisterService service = new RegisterService (); service.Name = "test server"; service.RegType = "_daap._tcp"; service.ReplyDomain = "local."; service.Port = 6060; // TxtRecords are optional TxtRecord txt_record = new TxtRecord (); txt_record.Add ("Password", "false"); service.TxtRecord = txt_record; service.Register(); Console.WriteLine("Service registered!"); Console.ReadLine(); } } } But I can't find my registered service with the sample client browser code nor with mzclient. Thanks!

    I'm currently using BlueCloth to process Markdown in Ruby and show it as HTML, but in one location I need it as plain text (without some of the Markdown). Is there a way to achieve that? Is there a markdown-to-plain-text method? Is there an html-to-plain-text method that I could feel the result of BlueCloth?

Please verify the installation of the component or download from the URL: http://go.microsoft.com/fwlink/?LinkId=49251 The URL of course points to SQL Server Express 2008. I have that one installed and running. Any ideas why am I getting that message?

  • Oracle .NET Provider DLL hell

    - by Pablo Santa Cruz
    I am currently developing on a Win7-32bits computer. Everything works fine. It's a ASP.NET application. I was able to use Microsoft's Oracle deprecated .NET provider to connect to Oracle (using 32 bit instant client) and also ODP.NET. No problems at all. Application runs fine. The problem comes when I deploy it to IIS7 on Windows 2008 Server 64bit computer. I can't get Microsoft's deprecated .NET provider or ODP.NET to work easily. Is there a straightforward way to use a 32bit based ODP.NET or Microsoft's Oracle deprecated .NET provider in Windows 2008 Server 64bits? DLL hell here! Thanks.

  • Stop multiple sessions accessing the same file simultaneously

    - by Pablo
    Is it possible to lock a file to stop it being opened while GD library is accessing it? What I am looking to achieve is similar to a database 'serialzable' level of isolation... I want to ensure that only one session/user can access an image at a time to stop a 'dirty read'. May application allows users to add an image of choice to a bigger image. for example the big image is empty Raj & Janet upload their images Raj's session opens the big image. 1 ms later Janet's session opens the big image. Raj's session add's his image and saves the big image 1 ms later Janet's session adds his image and saves its version of the big image. As a result Raj's image is not in the final image as Janet's version overwrote it. I hope that makes it clear enough.

  • ColdFusion structs Direct Assignment vs object literal notation.

    - by Tom Hubbard
    The newer versions of ColdFusion (I believe CF 8 and 9) allow you to create structs with object literal notation similar to JSON. My question is, are there specific benefits (execution efficiency maybe) to using object literal notation over individual assignments for data that is essentially static? For example: With individual assignments you would do something like this: var user = {}; user.Fname = "MyFirstnam"; user.Lname = "MyLastName"; user.titles = []; ArrayAppend(user.titles,'Mr'); ArrayAppend(user.titles,'Dr.'); Whereas with object literals you would do something like. var user = {Fname = "MyFirstnam", Lname = "MyLastName", titles = ['Mr','Dr']}; Now this limited example is admittedly simple, but if titles was an array of structures (Say an array of addresses), the literal notation becomes awkward to work with.
