• Build a JavaScript wrapper for a rails-generated XML API?

  - by Thor Thurn

  I am working with a large website written in Ruby on Rails. Thanks to the support for REST in Rails 2, the site's business logic is all accessible via a consistent XML API. Now I want to be able to easily write one or more JavaScript frontends to the site that interact with the generated Rails XML API. Ideally, an automated wrapper for the API could be created in JavaScript, since this would minimize the effort required in writing XML processing code for the more than 500 API functions. How, then, can I automatically generate a wrapper around a given XML API in JavaScript so that it's more pleasant to work with? I've worked with solutions of this nature for Java that generate classes and methods to wrap an API, so my current thinking is that I want something of that nature for JavaScript. I'd be open to an alternative take on the problem, though.

• How to override HTML <FONT SIZE="2"> with CSS

  - by Deverill

  I was given the task of doing a facelift to our current site. I am moderately well versed in CSS so I am converting the bazillion tags to CSS styles and deleting about 2 times that many that were simply not necessary. It's all going well until I run into a certain product page that is only a wrapper into which other HTML files are pulled by a server.execute(filename) command. (we're using aspx for the wrapper page.) There are almost 700 of these pages and they all are cursed with this and that. Past editors with FrontPage that only know how to drag pretty things on the screen. Anyway, I am wondering if there is a way to use CSS in the wrapper page to override the tag behavior so I can make it something sane that fits with the rest of my pages. I'd even be open to something JavaScript that would remove the tags, but that's my less preferred solution. Thanks!

• How should I structure my git commits?

  - by int3

  I'm trying to contribute to open source software for the first time, but I'm pretty inexperienced with version control systems. In particular, right now I want to make a number of changes to different parts of the code, but I'm not sure if the maintainer would want to integrate all of them into the master repository. However, the changes I'll be making are independent, i.e. they affect different parts of the file, or parts of different files. How should I go about making the changes? If I make a string of commits on the same branch, will the maintainer be able to pick and choose what he wants from the individual commit? E.g. can he patch in the changes I made in my second commit while ignoring the first one? Or should I make each change in a separate branch?

• How do I get the server hostname from a mounted directory with cocoa/obj-c?

  - by Andrew

  Currently when I open a file with my program I can select files on a server by clicking on the server name in the sidebar in an NSOpenPanel and then selecting the file. No problem, this works fine for using the file as long as the shared directory is mounted. I get a path like "/Volumes/SHARENAME/filename.bla". My question is how do I get the server hostname of the computer it came from. For instance, if I clicked on the device with name SERVERNAME under "Shared" in the NSOpenPanel how do I get SERVERNAME from "/Volumes/SHARENAME/filename.bla". I have looked at quite a bit of documentation and have been unable to find a solution for this problem. Any help toward this will be greatly appreciated. Thank you.

• Eclipse: How to add an existing source folder?

  - by evilfred

  ARGH Eclipse is SO frustrating I have a directory called c:\RemoteSrc . Under this there are 3 directories which are currently source folders (I think? the icon is an open folder with a little orange grid in it) in my Eclipse project. I have dropped a new directory under c:\RemoteSrc which I also want to add to my project. BUT If I right click on my project and go "Build Path..." - "Link Source" and try to add it it tells me "Folder already exists with a different case". Yes i KNOW that the folder already exists THATS WHY IM TRYING TO ADD IT.

• Encryption using rijndael

  Hi all. I'm quite new in programming .I wrote the below code in order to prompt the user for a password to encrypting a file, But it just work when the length of password is 8, What can I do on order to accepting any number of characters for the password? string pass = textBox2.Text.ToString(); string password = @"" + pass + ""; UnicodeEncoding UE = new UnicodeEncoding(); byte[] key = UE.GetBytes(password); FileStream fsCrypt = new FileStream(@"c:\\users\\new", FileMode.Create); name = fsCrypt.Name; RijndaelManaged RMCrypto = new RijndaelManaged(); CryptoStream cs = new CryptoStream(fsCrypt, RMCrypto.CreateEncryptor(key, key), CryptoStreamMode.Write); FileStream fsIn = new FileStream(filename, FileMode.Open); int data; while ((data = fsIn.ReadByte()) != -1) cs.WriteByte((byte)data);

• how do I detect OS X in my .vimrc file, so certain configurations will only apply to OS X?

  - by Brandon

  I use my .vimrc file on my laptop (OS X) and several servers (Solaris & Linux), and could hypothetically someday use it on a Windows box. I know how to detect unix generally, and windows, but how do I detect OS X? (And for that matter, is there a way to distinguish between Linux and Solaris, etc. And is there a list somewhere of all the strings that 'has' can take? My Google-fu turned up nothing.) For instance, I'd use something like this: if has("mac") " open a file in TextMate from vi: " nmap mate :w<CR>:!mate %<CR> elseif has("unix") " do stuff under linux and " elseif has("win32") " do stuff under windows " endif But clearly "mac" is not the right string, nor are any of the others I tried.

• Strange fstream problem

  - by noname

  Hi, I have really strange problem. In Visual C++ express, I have very simple code, just: #include <fstream> using namespace std; int main() { fstream file; file.open("test.txt"); file<<"Hello"; file.close(); } This same code works OK in my one project, but when I create now project and use this same lines of code, no file test.txt is created. Please, what is wrong?¨ EDIT: I expect to see test.txt in VS2008/project_name/debug - just like the first functional project does.

• Issue connecting to SQL Compact Edition on Windows Mobile 6 Emulator

  - by Chad

  I am developing an application for Windows Mobile 6 using an emulator. When I try to open the database connection to the SDF file it is throwing an exception that it is not able to connect or find the file. My questions are: Where on the mobile device is the SDF file supposed to be deployed? Does the SDF file get automatically deployed to the emulator when I build the project (like in then windows forms app) or do I have to do that manually? Any help would be appreciated.

• Integrate IPhone Safari like view in Android?

  - by sunil

  The main concept goes like this. I have four listviews with its own data loaded at the same time. Only one listview will be visible to the user. Now, when the user presses a button, not only the current listview but also other three listviews should be minimized and then user can just scroll just as in Gallery and select the listview that one wants to open. I hope you all have understood what I want. Let me know if someone have some idea of implementing such a User Interface in Android. Thanks & Regards Sunil

• How to create a tree with filtered nodes from drupal taxonomy.

  - by sprugman

  I'm trying to create a menu tree in drupal like this: - term 1 node 1 node 2 - sub-term 1 node 3 node 4 + sub-term 2 - sub-term 3 node 5 - sub-sub-term 1 node 6 + term 2 etc. (Sub-term 2 and term 2 are toggled closed.) Some requirements: Output this using something like JQuery Menu to get an interactive tree Filter the nodes by cck type Filter the nodes by cck field Only have terms with nodes or other active terms in them show up Mark the current node as such, and automatically open the tree to that point Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.

• Reading a triangle of numbers into a 2d array of ints in Python

  - by Gabriel Silk

  I want to read a triangle of integer values from a file into a 2D array of ints using Python. The numbers would look like this: 75 95 64 17 47 82 18 35 87 10 20 04 82 47 65 ... The code I have so far is as follows: f = open('problem18.input', 'r') arr = [] for i in range(0, 15): arr.append([]) str = f.readline() a = str.split(' ') for tok in a: arr[i].append(int(tok[:2])) print arr I have a feeling this could be done in a tighter, more Pythonesque way. How would you do it?

• Removing DIVs in a jquery dialog

  I have a dialog window that uses a URL for its contents { function(){jQuery.ajax({'success':function(html) { jQuery('#menu_dialog').html(html); $('#menu_dialog').dialog('open'); $('#header').hide(); },'url':'/testing/index.php/menu','cache':false});return false;}; } What happens is that it was displaying the whole page, including the header, the footer,navigation menu,etc. What I want is for the dialog to only display the content inside the <content> tag. How can I remove the unnecessary divs in the dialog window?

• Xcode missing Command Line Utility section - can't start Foundation project template

  - by Liza

  I downloaded the iPhone SDK from the iPhone dev center a couple of days ago and installed it yesterday. I'm following the Stanford iPhone development tutorials available on iTunes U. On Assignment 1B, the first instruction is to open a new Foundation Project template. The screenshot shows several sections in Xcode which my version doesn't seem to have, including the Command Line Utility section which the Foundation Project template is shown to be in. Does this need to be installed manually? I tried searching on Google with no luck. The fact that I'm an OS X newbie doesn't really help any either. Thanks in advance!

• XSL: Dead or not dead

  - by Seattle Leonard

  I'm currently taking on a new project at home. In this project I'm going to be generating HTML emails. For this purpose, I believe XSL to be a good candidate. However, I have heard people say that XSL is a dead language, and if it's not that it is on it's way out. In fact, MS has been very leary to support XSL 2.0. Personally I feel that any time you are going from text to text, it is a great tool. Such as: Generating HTML e-mails Creating Open Office Docs Generating another XML doc What are your thoughts? Is it dead, or is it still a viable, usefull tool?

• How can I override an HTML "rules" attribute using CSS?

  - by ajoten

  The DITA Open Toolkit automatically inflicts some inline table attributes when one publishes to HTML, including frame="border" and rules="all". I need to override this "rules" attribute using CSS styles for cells, and while I can get the desired result in IE and Chrome, Firefox puts solid black gridlines in the table and refuses to budge on the matter. Obviously I can't edit the HTML, company policy is to not edit the XSLT, so how can I remove these gridlines using CSS alone? I've tried various cunning combinations of border-xxxxxx styles and given them !important declarations to no effect. Thanks, Andrew

• Python Scraper for Javascript?

  - by Diego

  Hey all, Can anyone direct me to a good Python screen scraping library for javascript code (hopefully one with good documentation/tutorials)? I'd like to see what options are out there, but most of all the easiest to learn with fastest results... wondering if anyone had experience. I've heard some stuff about spidermonkey, but maybe there are better ones out there? Specifically, I use BeautifulSoup and Mechanize to get to here, but need a way to open the javascript popup, submit data, and download/parse the results in the javascript popup. <a href="javascript:openFindItem(12510109)" onclick="s_objectID=&quot;javascript:openFindItem(12510109)_1&quot;;return this.s_oc?this.s_oc(e):true">Find Item</a> I'd like to implement this with Google App engine and Django. Thanks!

• WCF on Win Server 2008 and IIS7 with only net.tcp binding hide IIS features

  - by Nicola Celiento

  Hi all, I've installed HTTP Activation and Non-HTTP Activation IIS's features for Framework.NET 3.0 under WCF Activation feature. I'm trying to remove http and https bindings (under default Web Site) from IIS Manager and leave others (net.tcp, net.msmq, etc.) but if I close and re-open IIS manager I not found any icons in the right panel (Feature View). The only feature I see is IIS Manager Permissions. It's right I don't see them? I hope you can help me. Thank you in advance!

• I want to query whitepages.com 4,000 times, how to save the results?

  - by John Corbin

  I have an old customer list of 4,000 businesses. I want to determine if the phone numbers associated with each listing are still working (and therefore the business is probably still open). I can put each number in whitepages.com and check them one by one... but want to automate the results. I have looked at their API and can't digest it. I can form the correct query URL, but trying things like cURL -O doesn't work. I have access to Mac tools, Unix tools, and could try various javascript stuff if anyone could point me in the right direction... would even pay. Help? Thx

• How do I change the effective user of psql?

  - by gvkv

  I'm using psql to run a simple set of COPY statements contained in a file: psql -d mydb -f 'wbf_queries.data.sql' where wbf_queries.data.sql contains lines: copy <my_query> to '/home/gvkv/mydata' delimiter ',' null ''; ... but I get a permission denied error: ... ERROR: could not open file ... for writing: Permission denied I'm connecting under my user account (gvkv) which is also a superuser in PostgreSQL. Obviously, psql is running under a different (effective) user but I don't know how to change this. Can it be done within psql or do I need some unix-fu?

• Fixing lots of broken references in a working asp.net mvc project

  - by davidbuttrick

  The last time I worked on this project everything was fine. That was about 4 days ago. Now, when I open the project, all the references to .Net are not working, I cannot build my project any more. I have tried following the advice in posts here, but to no avail. Even simple things, like Request.cookies - Request is underlined in curlies, and I get 'Request is undefined' when I roll over it. That doesnt seem like I need to just remove and recreate the reference to System.Web.Mvc - which I have tried, and had no luck. Any ideas? Surely there are other issues that can cause this problem... Thank you.

• Solve equation from string to result in C

  - by Alexandre Cassagne

  Hi, I would like to know if anyone has info or experience on how to do something which sounds simple but doesn't look like it when trying to program it. The idea is : give a string containing an equation, such as : "2*x = 10" for example (this is simple, but it could get very complex, such as sqrt(54)*35=x^2; and so on....) and the program would return x = 5 and possibly give a log of how he got there. Is this doable ? If so, does anyone have a lead ? For info there is this site (http://www.numberempire.com/equationsolver.php) which does the same thing in PHP, but isn't open source. Thanks for any help !

• Returning more than one result

  - by Hairr

  I'm using the following code: def recentchanges(bot=False,rclimit=20): """ @description: Gets the last 20 pages edited on the recent changes and who the user who edited it """ recent_changes_data = { 'action':'query', 'list':'recentchanges', 'rcprop':'user|title', 'rclimit':rclimit, 'format':'json' } if bot is False: recent_changes_data['rcshow'] = '!bot' else: pass data = urllib.urlencode(recent_changes_data) response = opener.open('http://runescape.wikia.com/api.php',data) content = json.load(response) pages = tuple(content['query']['recentchanges']) for title in pages: return title['title'] When I do recentchanges() I only get one result. If I print it though, all the pages are printed. Am I just misunderstanding or is this something relating to python? Also, opener is: cj = CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

• Simulating a cookie-enabled browser in PHP

  - by Itamar Benzaken

  How can I open a web-page and receive its cookies using PHP? The motivation: I am trying to use feed43 to create an RSS feed from the non-RSS-enabled HighLearn website (remote learning website). I found the web-page that contains the feed contents I need to parse, however, it requires to login first. Luckily, logging in can be done via a GET request so it's as easy as fopen()ing "http://highlearn.website/login_page.asp?userID=foo&password=bar" for example. But I still need to get the cookies generated when I logged in, pass the cookies to the real client (using setcookie() maybe?) and then redirect.
