  • Nokogiri and Special Characters

    - by Moe
    I'm using Nokogiri to grab the contents of the title tag on a webpage, but am having trouble with accented characters. What's the best way to deal with these? Here's what I'm doing: require 'open-uri' require 'nokogiri' doc = Nokogiri::HTML(open(link)) title = doc.at_css("title") At this point, the title looks like this: Rag\303\271 Instead of: Ragù How can I have nokogiri return the proper character (e.g. ù in this case)?

  • Database design: OR relation

    - by Ant
    I have a database with a "users" table containing data about my users. Each user is to be linked to a company or a college. I wish to have two separate tables "college" and "company" each with a field "ID". So how do I link each record in the users table to either a company or a college?

  • Solaris: Programmatic interface to ifconfig?

    - by David Citron
    I'm looking for a programmatic interface to the Solaris ifconfig(1M) command. Apparently Linux has the getifaddrs(3) command, but as far as I can tell this has not been ported to Solaris. Short of attempting to use the code at the link above, is there any way to determine ifconfig(1M)-type data (network interface presence, state, etc.) without forking the system command and parsing the output?

  • Converting from a string to boolean in Python?

    - by Joan Venge
    Does anyone know how to do convert from a string to a boolean in Python? I found this link. But it doesn't look like a proper way to do it. I.e. using a built in functionality, etc. EDIT: The reason I asked this is because I learned int("string"), from here. I tried bool ("string") but always got True.

  • Help with OpenSSL request using Python

    - by Ldn
    Hi i'm creating a program that has to make a request and then obtain some info. For doing that the website had done some API that i will use. There is an how-to about these API but every example is made using PHP. But my app is done using Python so i need to convert the code. here is the how-to: The request string is sealed with OpenSSL. The steps for sealing are as follows: • Random 128-bit key is created. • Random key is used to RSA-RC4 symettrically encrypt the request string. • Random key is encrypted with the public key using OpenSSL RSA asymmetrical encryption. • The encrypted request and encrypted key are each base64 encoded and placed in the appropriate fields. In PHP a full request to our API can be accomplished like so: <?php // initial request. $request = array('object' => 'Link', 'action' => 'get', 'args' => array( 'app_id' => 303612602 ) ); // encode the request in JSON $request = json_encode($request); // when you receive your profile, you will be given a public key to seal your request in. $key_pem = "-----BEGIN PUBLIC KEY----- MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALdu5C6d2sA1Lu71NNGBEbLD6DjwhFQO VLdFAJf2rOH63rG/L78lrQjwMLZOeHEHqjaiUwCr8NVTcVrebu6ylIECAwEAAQ== -----END PUBLIC KEY-----"; // load the public key $pkey = openssl_pkey_get_public($key_pem); // seal! $newrequest and $enc_keys are passed by reference. openssl_seal($request, $enc_request, $enc_keys, array($pkey)); // then wrap the request $wrapper = array( 'profile' => 'ProfileName', 'format' => 'RSA_RC4_Sealed', 'enc_key' => base64_encode($enc_keys[0]), 'request' => base64_encode($enc_request) ); // json encode the wrapper. urlencode it as well. $wrapper = urlencode(json_encode($wrapper)); // we can send the request wrapper via the cURL extension $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://api.site.com/'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, "request=$wrapper"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); curl_close($ch); ?> Of all of that, i was able to convert "$request" and i'v also made the JSON encode. This is my code: import urllib import urllib2 import json url = 'http://api.site.com/' array = {'app_id' : "303612602"} values = { "object" : "Link", "action": "get", "args" : array } data = urllib.urlencode(values) json_data = json.dumps(data) What stop me is the sealing with OpenSSL and the publi key (that obviously i have) Using PHP OpenSSL it's so easy, but in Python i don't really know how to use it Please, help me!

  • Wikipedia embedded in WinForms App Tutorial

    - by RHaguiuda
    Can anyone post a tutorial here on how to show a Wikipedia article in a .NET WinForms application (C# or VB)? If the article can be placed in a string it suffices, there`s no need to put it on any control. I found some information on Wikipedia's API. After reading it, I added the reference to web service but can`t find a way to make this work. And if it's possible, explain how images are downloaded from wiki (link or image itself).

  • Facebook - finding users by name

    - by Gublooo
    Hello Guys, I'm very new to facebook and wanted to know if this is even possible to do with facebook API. If a user searches for a name on my website - say "Jamie Smith" - I want to pass this name to facebook and find all users that match that name - so if I can get back their photo and name to display on my site - so users can identify the right person. I'm using PHP so if there's any example or link that you can provide will be really helpful. Thanks

  • iPhone Twitter Get UserId

    - by Mick Walker
    Hi, I am looking for a way to get a twitter users userid via their username. For example take http://twitter.com/AlySSa_miLAno (yes I know her twitter page off by heart lol) on the right hand side of the page is a link to her RSS feed: feed://twitter.com/statuses/user_timeline/26642006.rss In this context Alyssa's userid would be 26642006. Ideally I would like to avoid reading the full content of the page, as this could be quite expensive on a mobile device, so if anyone knows how to accomplish this using any Twitter/3rd party webservices that would be great.

  • Mechanize Javascript ...

    - by Horace Ho
    I try to submit a form by Mechanize, however, I am not sure how to add necessary form valuables which are done by some Javascript. Since Mechanize does not support Javascript yet, and so I try to add the variables manually. The form source: <form name="aspnetForm" method="post" action="list.aspx" language="javascript" onkeypress="javascript:return WebForm_FireDefaultButton(event, '_ctl0_ContentPlaceHolder1_cmdSearch')" id="aspnetForm"> <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__LASTFOCUS" id="__LASTFOCUS" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/..." /> <script type="text/javascript"> <!-- var theForm = document.forms['aspnetForm']; if (!theForm) { theForm = document.aspnetForm; } function __doPostBack(eventTarget, eventArgument) { if (!theForm.onsubmit || (theForm.onsubmit() != false)) { theForm.__EVENTTARGET.value = eventTarget; theForm.__EVENTARGUMENT.value = eventArgument; theForm.submit(); } } // --> </script> <script language="javascript"> <!-- var _linkpostbackhit = 0; function _linkedClicked(id, key, str, a, b) { if (!b || !_linkpostbackhit) { if (!a) { __doPostBack(key, id); _linkpostbackhit = 1; } else { if (window.confirm(str)) { __doPostBack(key, id); _linkpostbackhit = 1; } } } return void(0); } // --> </script> ... <a href="JavaScript:_linkedClicked('123456','_ctl0:ContentPlaceHolder1:Link', '',0,1);">123456</a> ... </form> I tried to add the 2 variables: page.forms.first['__EVENTTARGET'] = '_ctl0:ContentPlaceHolder1:Link' page.forms.first['__EVENTARUGMENT'] = '123456' and submit the form: page.forms.first.click_button(page.forms.first.buttons.first) The result returned only (re)show the current list of links as if I have not clicked on any of the links. Any help will be appreciated. Thanks!

  • Software to Tune/Calibrate Properties for Heuristic Algorithms

    - by Karussell
    Today I read that there is a software called WinCalibra (scroll a bit down) which can take a text file with properties as input. This program can then optimize the input properties based on the output values of your algorithm. See this paper or the user documentation for more information (see link above; sadly doc is a zipped exe). Do you know other software which can do the same which runs under Linux? (preferable Open Source)

  • Issues loading SWF with External SWF Files - using SWFObject and ExternalInterface

    - by wdense51
    I'm having issues with loading a SWF that references external SWF files... The main SWF loads fine if the HTML file is in the same folder as all the SWFs using the following code: <script type="text/javascript" src="../js/swfobject.js"></script> <script type="text/javascript"> var flashvars = {}; var params = { allowScriptAccess: "always" }; params.quality = "high"; params.wmode = "transparent"; var attributes = {id:"IDofSWF", name:"IDofSWF"}; swfobject.embedSWF("event_so_js.swf", "flashContent", "700", "400", "7.0.0", false, flashvars, params, attributes);</script> </head> <body> <div id="flashContent"> <object data="event_so_js.swf" name="IDofSWF" id="IDofSWF" type="application/x-shockwave-flash" width="700" height="400"></object></div> But as soon as I move the HTML file out of that folder to the root folder and update the links, it doesn't load correctly - it seems that it's having trouble with the external SWF files. I did have it successfully load one of the external SWF files directly, but it's having trouble with the main SWF. All of the SWF files are in the same folder, so I don't know why it's having issues. Here's the code for the HTML file when it's in the root folder: <script type="text/javascript" src="js/swfobject.js"></script> <script type="text/javascript"> var flashvars = {}; var params = { allowScriptAccess: "always" }; params.quality = "high"; params.wmode = "transparent"; var attributes = {id:"IDofSWF", name:"IDofSWF"}; swfobject.embedSWF("folio/event_so_js.swf", "flashContent", "700", "400", "9.0.0", false, flashvars, params, attributes);</script> </head> <body> <div id="flashContent"> <object data="folio/event_so_js.swf" name="IDofSWF" id="IDofSWF" type="application/x-shockwave-flash" width="700" height="400"></object></div> There is also a link on the page that calls a function in the actionscript using ExternalInterface, so it could be that causing the issues. The code for the link is: <a href="#" onclick="document.getElementById('IDofSWF').clicky()"> Any help would be awesome, because it's really confusing me.

  • WinAPI magic and MONO runtime

    - by Luca
    I'm trying to get the same result of a .NET application (see the link Hide TabControl buttons to manage stacked Panel controls for details), but using the MONO runtime instead of the MS .NET runtime. Pratically, when the custom control is executed using the MONO runtime, the underlying message is not sent to the control, causing the tab pages to be shown... Is there a portable solution which is elegant as the linked one? If it is not possible, what are possible workarounds (apart from removing/adding tabs at runtime)?
