  • Multiple hops tunnels howto

    - by ard
    I wonder if anyone is able to help me with multiple tunnel hops for servers... basically my setup looks something like this... [desktop01]=====[server01]=====[server02]---------[machine01] \--------[machine02] \-------[machine03] \------[machine04] I want to setup some ssh tunnels so that from my desktop I can ssh directly to machine01 through 04 without having to ssh to each box in between in turn... So desktop01 can only see server01, server02 can only accept connections from server01 and machines 01 to 04 only accept connections from server02. Can anyone help as im really stuck with this. Thank you in advance :)

  • Howto use FB Graph to post a message on a feed (wall)

    - by qualbeen
    I have created an app, and now i want to post a message on one of my friends wall with use of the new Graph API. Is this do-able? I am already using oAuth and the Graph-api to get a list of all my friends. The API at http://developers.facebook.com/docs/api tells me to cURL https://graph.facebook.com/[userid]/feed to read the feed, but it also tells me howto post a message: curl -F 'access_token=[...]' -F 'message=Hello, Arjun. I like this new API.' https://graph.facebook.com/arjun/feed Ofcourse this doesn't work! And I can't find out why.. Here are my PHP-code: require_once 'facebook.php'; // PHP-SDK downloaded from http://github.com/facebook/php-sdk $facebook = new Facebook(array(appId=>123, secret=>'secret')); $result = $facebook->api( '/me/feed/', array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..') ); This code does not throws any error, and I know my access_token are correct (otherwise i could't run $facebook-api('/me?access_token='.$this-access_token); to get my userobject. Have anyone out there sucsessfully posted a message using Graph-api? Then i need your help! :-)

  • how to use nokogiri methods .xpath & .at_xpath

    - by Radek
    I'm learning how to use nokogiri and few questions came to me based on the code below require 'rubygems' require 'mechanize' post_agent = WWW::Mechanize.new post_page = post_agent.get('http://www.vbulletin.org/forum/showthread.php?t=230708') puts "\nabsolute path with tbody gives nil" puts post_page.parser.xpath('/html/body/div/div/div/div/div/table/tbody/tr/td/div[2]').xpath('text()').to_s.strip.inspect puts "\n.at_xpath gives an empty string" puts post_page.parser.at_xpath("//div[@id='posts']/div/table/tr/td/div[2]").at_xpath('text()').to_s.strip.inspect puts "\ntwo lines solution with .at_xpath gives an empty string" rows = post_page.parser.xpath("//div[@id='posts']/div/table/tr/td/div[2]") puts rows[0].at_xpath('text()').to_s.strip.inspect puts puts "two lines working code" rows = post_page.parser.xpath("//div[@id='posts']/div/table/tr/td/div[2]") puts rows[0].xpath('text()').to_s.strip puts "\none line working code" puts post_page.parser.xpath("//div[@id='posts']/div/table/tr/td/div[2]")[0].xpath('text()').to_s.strip puts "\nanother one line code" puts post_page.parser.at_xpath("//div[@id='posts']/div/table/tr/td/div[2]").xpath('text()').to_s.strip puts "\none line code with full path" puts post_page.parser.xpath("/html/body/div/div/div/div/div/table/tr/td/div[2]")[0].xpath('text()').to_s.strip is it better to use // or / in xpath? @AnthonyWJones says that 'the use of an unprefixed //' is not so good idea I had to remove tbody from any working xpath otherwise I got 'nil' result. How is possible to remove an element from the xpath to get things work? do I have to use .xpath twice to extract data if not using full xpath? why I cannot make .at_xpath working to extract data? it works nicely here what is the difference?

  • How to learn high-level Java web development concepts

    - by titaniumdecoy
    I have some experience writing web applications in Java for class projects. My first project used Servlets and my second, the Stripes framework. However, I feel that I am missing the greater picture of Java web development. I don't really understand the web.xml and context.xml files. I'm not sure what constitutes a Java EE application as opposed to a generic Java web application. I can't figure out how a bean is different from an ordinary Java class (POJO?) and how that differs from an Enterprise Java Bean (EJB). These are just the first few questions I could think of, but there are many more. What is a good way to learn how Java web applications function from the top down rather than simply how to develop an application with a specific framework? (Is there a book for this sort of thing?) Ultimately, I would like to understand Java web applications well enough to write my own framework.

  • How to use iPhone SDK Private APIs

    - by eagle
    I haven't found a comprehensive list of the steps that are required to use a private API from the iPhone Library. In particular, I would like to know how to get header files, if they are even required, how to get it to compile (when I simply add the header, it complains that the functions aren't defined), and what resources one can use to learn about private APIs (e.g. from other user's experiences, such as http://iphonedevwiki.net/ which has a few). I've read in other places that people recommend using class-dump to get the headers. Are there any alternative methods? I've noticed that there are some repositories of iPhone Private SDKs, what are the most up to date resources you would recommend? Most of the previous questions about documentation of private APIs, have all linked to Erica Sadun's website, which doesn't seem to have documentation anymore (all the links on the left are crossed out). Please save the comments about not using private API's... I know of the biggest risks: App will get rejected by Apple. App will break in future updates to the OS. I'm talking about legitimate uses, such as: Private application use (e.g. for unit testing, or messing around to see what's possible)

  • How do you mock a Sealed class?

    - by Brett Veenstra
    Mocking sealed classes can be quite a pain. I currently favor an Adapter pattern to handle this, but something about just keeps feels weird. So, What is the best way you mock sealed classes? Java answers are more than welcome. In fact, I would anticipate that the Java community has been dealing with this longer and has a great deal to offer. But here are some of the .NET opinions: Why Duck Typing Matters for C# Develoepers Creating wrappers for sealed and other types for mocking Unit tests for WCF (and Moq)

  • Best way to "un-promote" files in Accurev?

    - by Luke Rinard
    My company uses Accurev for source control, and for all its benefits, there's one simple action that I just can't figure out how to accomplish. Often we have someone accidentally push a file up too far in our stream structure -- from the "Development" stream to the "Release" stream, for example. What is the best way to "un-promote" this file? That is to say, to get the old version of the file back into the "Release" stream, and keep the new version of the file in the "Development" stream, where it belongs? Just doing a "Revert to Backed" or other Revert action on the file in the Release stream will either cause an old version of the file to propagate down into Development, or will make the file disappear entirely. In the above case, the developer will have to jump through hoops with setting basis times on streams, or use the command line tool to do a checkout of an old transaction, to get the file back. Sometimes the people in question are non-technical, so this is not a good solution. I have also considered moving the files to a "higher ground" stream, reverting, and then cross-promoting them to the lower stream again. This seems really kludgy. It seems like Accurev is obscure enough that Google is no help, so I turn to the good folks of StackOverflow for help -- has anybody figured out the "Accurevy" way to accomplish this?

  • asp:repeater events - how to postback

    - by Kieran
    Hello I have an ASP:Repeater Which I would like to display a list of check boxes in. These check boxes are related to a list of user preferences and the users resulting answer. See Code Bellow. I would like to add do one of the following if possible Option 1: It would be great if I could use the Event in the Repeater:OnItemCommand(...) to fire if any of the items change. It would seem to me that this event will only fire if there is a Button | LinkButton | ImageButton item in the list. IE it will not fire if I put in a check box with AutopostBack="True" Option 2: Is there a way I could attach a method to an Event of CheckBox:CheckChanged I would need to pass this method a parameter saying which question/answer combo to change. Option 3: Its your answer if you know an easier way that would be awesome. The Code: <asp:Repeater ID="RPTprefs" runat="server" DataSourceID="getAnswers" OnItemCommand="RPTprefs_ItemCommand"> <ItemTemplate> <li><asp:CheckBox ID='questionID' runat="server" Checked='<%# Eval("pr.up_is_selected") %>' Text='<%# Eval("prp.prefs_question") %>' AutoPostBack="true" OnCheckedChanged="CheckChanged" /></li> </ItemTemplate> </asp:Repeater> Thanks in advance

  • How would you make a blog with a TDD approach?

    - by Earlz
    I'm considering remaking my blog(currently in PHP, but <100 lines of non-layout code) in Ruby on Rails just for the fun of it. I want to make another project in Rails, but I should learn Rails(more than hello world) before I go to try to create a full project. Another thing I want to do while remaking my blog is to at least figure out what TDD is all about. So how would you go about taking a Test Driven approach to the creation of a blog? What tests would you write? How would you begin? Everytime I visualize writing a blog it'd end up needing a million tests for a single component to fully test it. How do I avoid writing too many tests? Also, I am making this community wiki because I intend for this to basically be made into a mini tutorial/knowledge base...

  • How to exit an if clause

    - by Roman Stolper
    What sorts of methods exist for prematurely exiting an if clause? There are times when I'm writing code and want to put a break statement inside of an if clause, only to remember that those can only be used for loops. Lets take the following code as an example: if some_condition: ... if condition_a: # do something # and then exit the outer if block ... if condition_b: # do something # and then exit the outer if block # more code here I can think of one way to do this: assuming the exit cases happen within nested if statements, wrap the remaining code in a big else block. Example: if some_condition: ... if condition_a: # do something # and then exit the outer if block else: ... if condition_b: # do something # and then exit the outer if block else: # more code here The problem with this is that more exit locations mean more nesting/indented code. Alternatively, I could write my code to have the if clauses be as small as possible and not require any exits. Does anyone know of a good/better way to exit an if clause? If there are any associated else-if and else clauses, I figure that exiting would skip over them.
