• Go with Native or using phonegap ?

  - by knightrider

  Hello, I was about to develop iphone app and I want suggestion from the expert since I am totally newbie in it. I have one classified website which is written in php and mysql. What I want to create is Iphone app which can view those classifieds. There will be no complicated function at first version. It will be have different categories and query and display according to the category. And if there's new classified ad, they will get push notification. What I want to know is, what should i go with ? Native or using phonegap ? Is phonegap supports push notification ? Is native app can just get the results through mysql ? or do i need to change it to sql lite ? Any speed different between native and phone gap ? Any advantages and disadvantages ? Thanks.

• How do I setup a custom Gem.path using JRuby::Rack?

  - by Ben Hogan

  Hi Nick et al, I've been having some fun looking at to source code of JRuby-Rack and Rubygems to try to figure out how to solve a org.jruby.rack.RackInitializationException: no such file to load -- compass in my rackup script cased by require 'compass'. I'm passing in a custom 'gem.path' as a servlet init parameter and it is being correctly picked up by jruby-rack as far as I can tell by debugging in my rackup script: ENV['GEM_PATH'] => '/foo/lib/.jruby/gems' (expected) but rubygems seems to be broken: Gem.path => file:/foo/lib/jruby-complete-1.4.0.jar!/META-INF/jruby.home/lib/ruby/gems/1.8 I'm not sure why rubygems has not adjusted it's gem_path nor the LOAD_PATH, thus breaking require? Thanks again, I'm still a newbie at ruby, jruby, rack and sinatra. Any pointers in the right direction appreciated! Ben

• Keyboard Navigation of File Open Dialog in Windows 7

  - by dkusleika

  In Windows XP standard File - Open dialog, the top has a "Look In" box. I can press Alt+I to drop down a tree of the disks folders and easily navigate to other folders or network shares. In Windows 7, I can't seem to navigate the File - Open dialog as easily. The best I've been able to muster is to tab 5 times (in Excel 2007, but I assume it's a windows standard), then use arrow keys or use Alt+arrow keys like a browser to get around. It's simply not as good because I can't see the whole tree at once. Is there a way to see the whole folder tree? If not, do you have any other tips for keyboard navigation of the file open dialog in Windows 7?

• Rails request forgery protection settings

  - by Vitaly

  Hey, please help a newbie in Rails :) I have protect_from_forgery call (which is given by default) with no attributes in my ApplicationController class. Basically here's the code: class ApplicationController < ActionController::Base helper :all # include all helpers, all the time protect_from_forgery helper_method :current_user_session, :current_user filter_parameter_logging :password, :password_confirmation What I assume it should do is: it should prevent any POST requests without correct authenticity_token. But when I send post request with jQuery like the one below, it works fine (there's update statement that is executed in the database)! $.post($(this).attr("href"), { _method: "PUT", data: { test: true } }); I see in console that there's no authenticity_token among sent parameters, but request is still considered valid. Why is that?

• Clipboard: Copy image, get path back when pasting in file input.

  - by disown

  Hi All. First question here on superuser. I sometimes get ad-hoc bug reports from customers, which I need to transfer to our online bug tracker. Works fine for text, but pictures are tedious. I'm looking for a solution to copy-paste images from documents (like excel sheets) in a way that if you paste an image to a file input (or text input) on a html page, the file will automatically be written to disk (tmp dir), and the path written to the file input field. This question is related to Directly paste clipboard image into gmail message, but I would like to ask if there is a solution using a local program only. I'm interested in solutions for all OS's.

• DotNetOpenAuth OpenIdTextBox For Google/Yahoo

  - by user300992

  If I want to integrate DotNetOpenAuth (primary for people to use their Google/Yahoo accounts to login, not act as provider) into my existing site, is this one line control good enough? <rp:OpenIdTextBox ID="OpenIdTextBox1" runat="server" /> Say, if a user wants to login as Google, I can simply set the textbox to "https://www.google.com/accounts/o8/id" and then they can login. I tried it with my Google account, it seems working and I can get the token from HttpContext.Current.User.Identity.Name. Is this "one line" solution secure enough for production? or is it a "must" that I have to use "OpenIdSelector" or "OpenIDLogin" control? I also opened the .net template and some samples, they are very complicated. There are PAPE policies, xrds.aspx (for discovery), ConsumerKey + ConsumerSecret...etc. As a newbie, I am very confused. Any tips on this will be really appreciated. Thanks

• How do I access session data in Jinja2 templates (Bottle framework on app engine)?

  - by TylerW

  Hello! I'm running the micro framework Bottle on Google App Engine. I'm using Jinja2 for my templates. And I'm using Beaker to handle the sessions. I'm still a pretty big Python newbie and am pretty stoked I got this far :) My question is how do I access the session data within the templates? I can get the session data no problem within the actual python code. And I could pass the session data each time I call a jinja template. But since I need the session data in the main menu bar of the site... that means I would have to pass it on every single page. Does anyone know if I can access it directly in the templates? For example I need the session data for my header links: Home | FAQ | Login or Home | FAQ | Logout Any help is greatly appreciated! :D

• Version Control for developers new to source control

  - by Daisetsu

  I've been writing code for a few years now and our backup strategy has been to zip the entire code directory up every few days and put it somewhere else on your hard drive, or occasionally upload it to some online file hosting service. Unfortunately the file hosting service got canceled without telling me and we lost years of backups. It's come down to the point where I finally have to learn to use version control. The only problems are My boss really doesn't like SVN, he tried it and it had a high learning curve (at least his client). We need a reliable place to host it (we can pay a reasonable amount). Can someone suggest what may be the best version control system and client for a newbie which won't be too annoying. Second what is a good remote version control service?

• Functional Programming - Lots of emphasis on recursion, why?

  - by peakit

  I am getting introduced to Functional Programming [FP] (using Scala). One thing that is coming out from my initial learnings is that FPs rely heavily on recursion. And also it seems like, in pure FPs the only way to do iterative stuff is by writing recursive functions. And because of the heavy usage of recursion seems the next thing that FPs had to worry about were StackoverflowExceptions typically due to long winding recursive calls. This was tackled by introducing some optimizations (tail recursion related optimizations in maintenance of stackframes and @tailrec annotation from Scala v2.8 onwards) Can someone please enlighten me why recursion is so important to functional programming paradigm? Is there something in the specifications of functional programming languages which gets "violated" if we do stuff iteratively? If yes, then I am keen to know that as well. PS: Note that I am newbie to functional programming so feel free to point me to existing resources if they explain/answer my question. Also I do understand that Scala in particular provides support for doing iterative stuff as well.

• How to apply the shake effect to a dialog with an embedded form

  - by Felix Guerrero

  Hi. I'm newbie on this, I'm trying to apply the shake effect to a dialog that has an embedded form but not success on this. When I try to trigger the effect $("#divDialogContainer").effect("shake", {times: 3}, 80); only the fields inside the form tag is taking the effect but the dialog box itself doesn't. My div Code My dialog $("#restore_password").dialog({ height: 220, width: 310, autoOpen: false, modal: true, draggable: false, resizable: false, show: 'puff', hiden: 'puff', buttons: { "Confirm": function(){ $("#change_password").dialog('open'); }, "Cancel": function(){ $(this).dialog('close'); $("#forgot_data").dialog('close'); $("#dialog-form").dialog('open'); setTimeout(function(){ $("#name").focus(); }, 800); } }, close: function() { allFields.val('').removeClass('ui-state-error'); } }); Any ideas?, it would be helpful.

• Passing parameters to a flash movie inserted in a VB program

  - by Michael

  Hi! I need to insert a Flash movie in a Visual Basic 2008 express form and send parameters to the movie, but am a newbie to VB. The flash movie will plot points sent by VB in a graph. I tried to insert the Shockwave Flash control in the form but cannot find it anywhere. So I inserted the webbrowser control, which I understand can be used to a similar purpose. But how would I send the values of X and Y (coordinates to plot in Flash) to the flash swf? Thanks for any help!

• Return a pointer to a char array in C

  - by snitko

  I've seen a lot of questions on that on StackOverflow, but reading the answers did not clear that up for me, probably because I'm a total newbie in C programming. Here's the code: #include <stdio.h> char* squeeze(char s[], char c); main() { printf("%s", squeeze("hello", 'o')); } char* squeeze(char s[], char c) { int i, j; for(i = j = 0; s[i] != '\0'; i++) if(s[i] != c) s[j++] = s[i]; s[j] = '\0'; return s; } It compiles and I get segmentation fault when I run it. I've read this faq about about returning arrays and tried the 'static' technique that is suggested there, but still could not get the program working. Could anyone point out exactly what's wrong with it and what should I be paying attention in the future?

• Outlook 2010 corrupts all Office attachments on a Server 2008R2 Remote Desktop Server

  - by Zhadu

  I have a rather annoying problem with a clients new Remote Desktop server. The problem is that any and all Office attachments (tested with Word and Excel documents) sent to the users via email cannot be opened due to the file seemingly being corrupted/damaged. I have determined that it is a local problem on the server, as the attachments work fine on my own pc. Also I believe the problem is isolated to Outlook, as the users can open already stored Office files without any issues. What are your thoughts on this? Extra information: The server is running Microsoft Server 2008 R2. The Office is a version 2010. It is handeling the roles of AD and RDS - The client only has one server, hence the breach of best practise. There is currently no AV software on the server. I have tried running a repair as well as a reinstalling of Office, with the error still there.

• Image animation over CGContextDrawPDFPage

  - by BittenApple

  I have a pdf page displayed with CGContextDrawPDFPage in QuartzDemo sample application. I want to keep this page shown and have an image slide in from top over this page, just as it can be seen in the iBooks application. It's a book, the sliding image is a bookmark that slides in when you are about to close the book. I added this code by DyingCactus (hint: im a newbie to obj c and iphone dev) as follows: In QuartzViewController.m, the animation starts to show but the view slides away before the animation is finished, in fact I think the animation goes on while the view is sliding away. -(void)viewWillDisappear:(BOOL)animated { [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations]; } How can I keep the view visible and finish the animation before view disappears?

• Why does python use 'magic methods'?

  - by Greg Beech

  I've been playing around with Python recently, and one thing I'm finding a bit odd is the extensive use of 'magic methods', e.g. to make its length available an object implements a method def __len__(self) and then it is called when you write len(obj). I was just wondering why objects don't simply define a len(self) method and have it called directly as a member of the object, e.g. obj.len()? I'm sure there must be good reasons for Python doing it the way it does, but as a newbie I haven't worked out what they are yet.

• Is it possible to rename an open Word document without closing it?

  - by RoboShop

  I just ask this question as I do not believe that after so many versions of Word, it wouldn't exist. Usually when I'm working on a document and I realize I have to rename it, I have to close the document down, go to file explorer and then rename it, and then opening it up again. It's a procedure that's so ingrained in my usage pattern that I didn't realize until now that I'm actually having to open and close multiple windows/ applications etc. simply to rename a file. Surely, it's the year 2012, I should be able to do a simple thing like that with a few clicks right? So is there a way to just rename the file name of a word /excel / office document without having to close it first?

• relational database: how to design this table

  - by donpal

  I'm a database newbie designing a database. I'll use SO to ask my question because it's easier to ask it on something that you can see already, but it's not the same, it will just help me understand the right approach. As you can see, there are many questions here and each can have many answers. How should I store the answers in a table? Should I store all the answers in the SAME table with a unique id (make it the key) and just a new field for the question id? What if there are 100,000 answers like there is here? Do I still store them in 1 table? What keys should I use to minimize search time when I want to search for the answers of a specific question? The database is both read and write if that makes any difference in this case.

• Regex and PHP for extracting contents between tags with several line breaks

  - by John

  How can I extract the content between tags with several line breaks? I'm a newbie to regex, who would like to know how to handle unknown numbers of line break to match my query. Task: Extract content between <div class="test"> and the first closing </div> tag. Original source: <div class="test">optional text<br/> content<br/> <br/> content<br/> ... content<br/><a href="/url/">Hyperlink</a></div></div></div> I've worked out the below regex, /<div class=\"test\">(.*?)<br\/>(.*?)<\/div>/ Just wonder how to match several line breaks using regex. There is DOM for us but I am not familiar with that.

• HBase schema help

  - by Jody Powlette

  Coming from a SQL Server background, I'm a newbie with regard to HBase, but the technology looks to be a good fit for what we're doing and the cost is definitely right! I need to maintain a list of log entries which normally I would create in an RDBS as: create table Log ( UserID int, SiteID int, Page varchar(50), Date smalldatetime ) where one user may have 0 or 1000 rows in this simple table. Typical queries would be to find all the rows for one user or all the rows for one user on one site. How does this translate into a "map" in HBase where there is no "row key" AND the same (SiteID,Page) may appear many times. My first thought is that UserID is a row key, but I still don't understand "column families" and the other terminology well enough to understand how to setup the table to hold this data where the one UserID can have many (SiteID,Page,Date) "rows". Any direction is appreciated!

• Is there a plugin for default file location in sublime text 2?

  - by Vasek

  Is there a plugin (or a setting) in Sublime Text 2 to set the default file location for saving files? As of now, when I open Sublime Text 2 for the first time, create a file and try to save it, the file location option defaults to: C:\Windows\System32 I would like to set the default save file location to my Desktop so that everytime I want to save a file, the File windows opens the Desktop view. (the same idea as what can be configured e.g. in MS Word / MS Excel). Thanks for any tips!

• Need an algorithm to group several parameters of a person under the persons name

  - by QuickMist

  Hi. I have a bunch of names in alphabetical order with multiple instances of the same name all in alphabetical order so that the names are all grouped together. Beside each name, after a coma, I have a role that has been assigned to them, one name-role pair per line, something like whats shown below name1,role1 name1,role2 name1,role3 name1,role8 name2,role8 name2,role2 name2,role4 name3,role1 name4,role5 name4,role1 ... .. . I am looking for an algorithm to take the above .csv file as input create an output .csv file in the following format name1,role1,role2,role3,role8 name2,role8,role2,role4 name3,role1 name4,role5,role1 ... .. . So basically I want each name to appear only once and then the roles to be printed in csv format next to the names for all names and roles in the input file. The algorithm should be language independent. I would appreciate it if it does NOT use OOP principles :-) I am a newbie.

• Connecting to external MySQL DB from a web server not running MySQL

  - by jrb04c

  While I've been working with MySQL for years, this is the first time I've run across this very newbie-esq issue. Due to a client demand, I must host their website files (PHP) on a IIS server that is not running MySQL (instead, they are running MSSQL). However, I have developed the site using a MySQL database which is located on an external host (Rackspace Cloud). Obviously, my mysql_connect function is now bombing because MySQL is not running on localhost. Question: Is it even possible to hit an external MySQL database if localhost is not running MySQL? Apologies for the rookie question, and many thanks in advance.

• Incremental backups in Quickbooks 2005

  - by Nathan DeWitt

  My church uses Quickbooks 2005. They have a backup to a 512 MB thumbdrive. They have been backing up about every week for the past 18 months. The filesize of the backups have grown from 14 MB to about 23 MB. I was planning on giving them a 1 or 2 GB thumb drive and calling it a day, but when I dumped this info into Excel and projected out the growth rate, I found that we'll hit 1 GB in July, and 10 GB in about another 18 months, and then 100 GB about 18 months after that. It looks to me like Quickbooks saves all the transactions with every backup. Is there a way to force incremental backups? If this is the way it is, that's fine, but I'd rather not keep buying another order of magnitude of storage space every 18 months. Can I safely delete the previous backups, and just keep the recent 2 or 3 months worth? Thanks.

• Winforms - Visually remove button click event

  - by Wayne Koorts

  .NET newbie alert Using Visual C# 2008 Express Edition I have accidentally created a click event for a button. I then deleted the automatically-created method code, which resulted in an error saying that the function, which had now been referenced in the form loading code, could no longer be found. Deleting the following line from the Form1.Designer.cs file's InitializeComponent() function... this.btnCopy.Click += new System.EventHandler(this.btnCopy_Click); ... seems to do the trick, however, it makes me feel very dirty because of the following warning at the beginning of the #region: /// Required method for Designer support - do not modify /// the contents of this method with the code editor. I haven't been able to find a way to do this using the form designer, which I assume is the means implied by this warning. What is the correct way to do this?
