• Rails: Obfuscating Image URLs on Amazon S3? (security concern)

  - by neezer

  To make a long explanation short, suffice it to say that my Rails app allows users to upload images to the app that they will want to keep in the app (meaning, no hotlinking). So I'm trying to come up with a way to obfuscate the image URLs so that the address of the image depends on whether or not that user is logged in to the site, so if anyone tried hotlinking to the image, they would get a 401 access denied error. I was thinking that if I could route the request through a controller, I could re-use a lot of the authorization I've already built into my app, but I'm stuck there. What I'd like is for my images to be accessible through a URL to one of my controllers, like: http://railsapp.com/images/obfuscated?member_id=1234&pic_id=7890 If the user where to right-click on the image displayed on the website and select "Copy Address", then past it in, it would be the SAME url (as in, wouldn't betray where the image is actually hosted). The actual image would be living on a URL like this: http://s3.amazonaws.com/s3username/assets/member_id/pic_id.extension Is this possible to accomplish? Perhaps using Rails' render method? Or something else? I know it's possible for PHP to return the correct headers to make the browser think it's an image, but I don't know how to do this in Rails... UPDATE: I want all users of the app to be able to view the images if and ONLY if they are currently logged on to the site. If the user does not have a currently active session on the site, accessing the images directly should yield a generic image, or an error message.

• Django ModelForm Imagefield Upload

  - by Wei Xu

  I am pretty new to Django and I met a problem in handling image upload using ModelForm. My model is as following: class Project(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=2000) startDate = models.DateField(auto_now_add=True) photo = models.ImageField(upload_to="projectimg/", null=True, blank=True) And the modelform is as following: class AddProjectForm(ModelForm): class Meta: model = Project widgets = { 'description': Textarea(attrs={'cols': 80, 'rows': 50}), } fields = ['name', 'description', 'photo'] And the View function is: def addProject(request, template_name): if request.method == 'POST': addprojectform = AddProjectForm(request.POST,request.FILES) print addprojectform if addprojectform.is_valid(): newproject = addprojectform.save(commit=False) print newproject print request.FILES newproject.photo = request.FILES['photo'] newproject.save() print newproject.photo else: addprojectform = AddProjectForm() newProposalNum = projectProposal.objects.filter(solved=False).count() return render(request, template_name, {'addprojectform':addprojectform, 'newProposalNum':newProposalNum}) the template is: <form class="bs-example form-horizontal" method="post" action="">{% csrf_token %} <h2>Project Name</h2><br> {{ addprojectform.name }}<br> <h2>Project Description</h2> {{ addprojectform.description }}<br> <h2>Image Upload</h2><br> {{ addprojectform.photo }}<br> <input type="submit" class="btn btn-success" value="Add Project"> </form> Can anyone help me or could you give an example of image uploading? Thank you!

• Using DisplayFor inside a display template

  - by Oenotria

  I've created a htmlhelper extension to reduce the amount of repetitive markup when creating forms: public static MvcHtmlString RenderField<TModel, TValue>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TValue>> expression) { return htmlHelper.DisplayFor(expression, "formfield"); } The idea being that inside my views I can just write @Html.RenderField(x=>x.MyFieldName) and it will print the label and the field's content with the appropriate div tags in place already. Inside the displaytemplates folder I have created formfield.cshtml containing the following: <div class="display-group"> <div class="display-label"> @Html.LabelFor(x => x) </div> <div class="display-field"> @Html.DisplayFor(x => x) </div> </div> Unfortunately it doesn't appear that it is possible to nest DisplayFor inside a display template (it doesn't render anything). I don't want to just using @Model because then I won't get checkboxes for boolean values, calendar controls for dates etc. Is there a good way around this?

• IE8, XHTML, position: fixed; and z-index.

  - by Joel

  I have an XHTML 1.0 transitional Doctype. I have a <div> that is position: fixed; bottom: 0px; left: 0px; width: 100%; z-index: 200;. Inside that <div> I have two buttons which are position relative, aligned right, with a set z-index of 201; In Firefox the bar at the bottom and the two buttons are correctly located at the bottom. In IE8 however, the bar is visible and the z-index appears to be overlaying the other content, but the buttons are hidden behind the main div, despite being children and having their z-index set. I'm using the following meta tag; <meta http-equiv="X-UA-Compatible" content="IE=edge" /> to force the document into IE8 mode. If I emulate IE7 (put on compatability mode), the bar and buttons work just fine. I don't understand how IE7's rendering is better than IE8. I don't want to have to force compatability mode due to other things that IE7 cannot render and IE8 can. Is there another solution, or have I missed something? Thanks.

• Does Zend Navigation view helper has a uri integrity check?

  - by simple

  I am kind a confused, though I am using the uri's, it doesn't render child menu items when uri has nonexisting element(madule name||controller name) <tours> <label>Tours</label> <uri>/admin/tour/index/list</uri> <class>admin-main-navigation-item ui-corner-right</class> <pages> <add> <label>Add</label> <uri>/admin/tour/index/form/type/add</uri> </add> <edit> <label>Edit</label> <uri>/admin/tour/index/list</uri> </edit> </pages> </tours> the edit and add item are not rendered because of the "admin" - is a dummy word that I use to distinguish if it is a frontend or backend of the module. any help would be appreciated, thanks

• Threading in Android

  - by virsir

  I am currently developing Android app, it needs download content from internet. I use thread to do that and then call runOnUiThread method to update GUI. I placed a refresh menu on it, if user tried to refresh the content, the download thread will be created and started. The problem is that how can I control the thread order, I need to accept the latest request's response and abandon previous thread requests if there were some other requests still running because the request parameters may have been changed by user. Currently I was using a threadId to do this thing, when a thread finished, it will check its threadId, if it was the latest recored one, it then takes control and render the response. My question is that is there any other proper better solution for this? Do I need to stop threads when user exit the app? I remember that some book said that do not try stop thread manually and wait itself finish is a good practice, is that true? Should I stop them by calling "stop" or "interrupt" method? I read some documents around threading in Android and found the class HandlerThread, what is it? In what kind of situation I need to use it?

• Converting json data to an HTML table

  - by dnaluz

  I have an array of data in php and I need to display this data in a HTML table. Here is what an example data set looks like. Array( Array ( [comparisonFeatureId] => 1182 [comparisonFeatureType] => Category [comparisonValues] => Array ( [0] => Not Available [1] => Standard [2] => Not Available [3] => Not Available ) [featureDescription] => Rear Seat Heat Ducts ),) The dataset is a comparison of 3 items (shown in the comparisonValues index of the array) In the end I need the row to look similar to this <tr class="alt2 section_1"> <td><strong>$record['featureDescription']</strong></td> <td>$record['comparisonValues'][0]</td> <td>$record['comparisonValues'][1]</td> <td>$record['comparisonValues'][2]</td> <td>$record['comparisonValues'][3]</td> </tr> The problem I am coming across is how to best do this. Should I create the entire table HTML on the server side pass it over an ajax call and just dump pre-rendered HTML data into a div or pass the json data and render the table client side. Any elegant suggestions? Thanks in advanced.

• Why won't Internet Explorer (or Chrome) display my 'Loading...' gif but Firefox will?

  - by codeLes

  I have a page that fires several xmlHttp requests (synchronous, plain-vanilla javascript, I'd love to be using jquery thanks for mentioning that). I'm hiding/showing a div with a loading image based on starting/stopping the related javascript functions (at times I have a series of 3 xmlhttp request spawning functions nested). div = document.getElementById("loadingdiv"); if(div) { if(stillLoading) { div.style.visibility='visible'; div.style.display=''; } else { div.style.visibility='hidden'; div.style.display='none'; } } In Firefox this seems to work fine. The div displays and shows the gif for the required processing. In IE/Chrome however I get no such feedback. I am only able to prove that the div/image will even display by putting alert() methods in place with I call the above code, this stops the process and seems to give the browsers in question the window they need to render the dom change. I want IE/Chrome to work like it works in Firefox. What gives?

• Pass variable to Info Window in FusionTableLayer

  - by user1030205

  I am building a web application that includes a Google Map layered with data from a Google Fusion Table. I have defined the info window for the markers in the Fusion Table and all is rendering as expected, but I have one issue. I need to pass a session variable from my web application to be included in the links that are defined in the info window, but can't seem to find a way to do this. Below is the javascript I am currently using to render the map: var myOptions = { zoom: 10, mapTypeId: google.maps.MapTypeId.ROADMAP, center: new google.maps.LatLng( 40.4230,-98.7372) } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); // Weather weatherLayer = new google.maps.weather.WeatherLayer({ temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT }); weatherLayer.setMap(map); //Hobby Stores var storeLayer = new google.maps.FusionTablesLayer({ query: { select: "col2", from: "3991553" }, map: map, supressInfoWindows: true }); //Club Sites var siteLayer = new google.maps.FusionTablesLayer({ query: { select: "col13", from: "3855088" }, styles: [{ markerOptions: { iconName: "airports" }}], map: map, supressInfoWindows: true }); I'd like to be able to pass some type of parameter in the call to google.maps.FusionTableLayer that passes a value to be include in the info window, but can't find a way to do this. To view the actual page, visit www.dualrates.com. Enter your zipcode and select one of the airport markers to see the info window. You may have to zoom the map out to see an airfield.

• Embed javascript in markdown

  - by Paul Tarjan

  I'm using the Maruku markdown processor. I'd like this *blah* blah "blah" in [markdown](blah) <script src="code.jquery.com/jquery-1.4.2.min.js"></script> <script> ...do stuff... </script> but it complains when I render it with a multitude of errors. The first one being ___________________________________________________________________________ | Maruku tells you: +--------------------------------------------------------------------------- | Could you please format this better? | I see that "<script type='text/javascript'>" is left after the raw HTML. | At line 31 | raw_html |<script src='http://code.jquery.com/jquery-1.4.2.min.js' /><script type='text/javascript'>| | text --> |//<![CDATA[| and then the rest seems like the parser is going nuts. Then it renders the javascript into a div on the page. I've tried making it a CDATA block and extra spacing between the jquery and my script. Help?

• STI and accepts_nested_attributes_for in rails

  - by ryanshackintosh

  I have models as follows: class Entity < ActiveRecord::Base has_many :addresses accepts_nested_attributes_for :addresses, :reject_if => lambda { |a| a[:label].blank?} , :allow_destroy => true end class Client < Entity before_save :set_type private def set_type self.type = "Client" end end class Address < ActiveRecord::Base belongs_to :entity end I have recently implemented accepts_nested_attributes_for on the /clients/new form, as follows: <% form_for(@client, :html => {:class => 'form'}) do |f| -%> <%= f.label :name %> <%= f.text_field :name -%> <%= f.label :phone %> <%= f.text_field :phone %> <% f.fields_for :addresses do |a| %> <%= a.label :street %> <%= a.text_field :street%> <%= a.label :city %> <%= a.text_field :city %> <% end %> <% end %> And my controller as follows: class ClientsController < ApplicationController before_filter :load_client , :except => [:index, :new, :create, :render_clients] def new @client = Client.new @client.addresses.build end def create @client = Client.new(params[:client]) if @client.save flash[:notice] = 'Client has been successfully added' redirect_to @client else render :action => 'new' end end The issue is that when the record is saved it gives an error stating: "Entity can't be blank" I assume it is something to do with the fact that a 'Client' and not an 'Entity' is being added. Can anyone point me in the right direction?

• Struts2 jQuery Plugin Autocompleter renders HTML with style attributes <== changing this?

  - by Tim

  I'm using the Struts2 jQuery plugin 2.1 and render an autocompleter in my JSP. Here's the code: <s:form id="search-form" action="search" theme="simple"> <s:url id="remoteurl" action="jsonlanguages"/> <div> <sj:autocompleter cssClass="bgstandardelement empty" id="languages" name="echo" href="%{remoteurl}" delay="50" value="Search..." /> <input type="submit" id="search-button" value="GO" /> </div> </s:form> No matter what theme I set the autocompleter-form to, the HTML rendered for the list I output is always an unordered list with a style element that I cannot override. It has the following stype-attribute: style='z-index: 1; top: 242px; left: 926px; display: none; width: 256px'; As I want another outfit for my list, this doesn't work. Putting in the following attribute has no effect: cssStyle="width:115px!important;" What can I do?

• Meteor: how to update DOM via Javascript without a page refresh?

  - by strack

  UPDATE: It looks like this script may be the catalyst I'm looking for. Will test it and answer/close this question if so. I'm sure I'll find the answer to this eventually, but I'm putting it out there now, in case someone else knows it right off... I am using RaphaelJS to manipulate the DOM (adds a bunch of SVG tags to an identified DIV), and I want to re-render those specific DOM parts, if there's an update to the MongoDB collection. As an example: -Let's say that I have a collection called PiePieces. -When the page is first rendered/ called, let's pretend that the number of pieces in the collection is 4. -I programmatically add a pie piece using console: PiePieces.insert({...}) -I want the page to update like it would for a standard handlebars binding situation, but the problem is, the new entry needs to go through the Raphael script, which performs direct DOM manipulation. So, the logic would go something like this: MongoDB collection update event - Client function call to manipulate DOM - DOM modified/ page updated without a refresh. I've tried implementing this by reading values from the DOM itself, and I can get the updated DOM, but the entire page refreshes and/or I have to manually refresh the page, OR the DOM tree isn't completed yet, and so it's blank until I refresh. Can you point me in the right direction, maybe with a small code snippet/example? (if something similar already exists, just tell me where and I'll go digging) Thanks in advance! (I am LOVING Meteor so far...)

• SVG text - total length changes depending on zoom

  - by skco

  In SVG (for web-browsers), if i add a <text>-element and add some text to it the total rendered width of the text string will change depending on the scale of the text. Lets say i add "mmmmmmmmmmmmmmmmmmmmmmmmmmA" as text, then i want to draw a vertical line(or other exactly positioned element) intersecting the very last character. Works fine but if i zoom out the text will become shorter or longer and the line will not intersect the text in the right place anymore. The error can be as much as +/- 5 characters width which is unacceptable. The error is also unpredictable, 150% and 160% zoom can add 3 characters length while 155% is 2 charlengths shorter. My zoom is implemented as a scale-transform on the root element of my canvas which is a <g>. I have tried to multiply the font-size with 1000x and scale down equally on the zoom-transform and vice versa in case it was a floating point error but the result is the same. I found the textLength-attribute[1] which is supposed to adjust the total length so the text always end where i choose but it only works in Webkit. Firefox and Opera seems to not care at all about this value (haven't tried in IE9 yet). Is there any way to render text exactly positioned without resorting to homemade filling of font-outlines? [1] http://www.w3.org/TR/SVG11/text.html#TextElementTextLengthAttribute Update Snippet of the structure i'm using <svg> <g transform="scale(1)"> <!--This is the root, i'm changing the scale of this element to zoom --> <g transform="scale(0.014)"> <!--This is a wrapper for multi-line text, scaling, other grouping etc --> <text font-size="1000" textLength="40000">ABDCDEFGHIJKLMNOPQRSTUVXYZÅÄÖabcdefghijklmnopqrstxyzåäö1234567890</text> </g> </g>

• Is it possible to anti alias using Copy swap effect?

  - by Nor

  I'm developing an application in VB.Net using Managed DirectX that runs in windowed mode and renders onto a picture box that is smaller than the form. Whenever I resize the form, the back buffer is streched to fit the picture box. This is not what I would like. The backbuffer size is the same as screen size, however, I only want to render a part of the back buffer, whose size is controlled by the size of the picture box into which I'm rendering. Resetting the device with new presentation parameters is something I would like to avoid. I'm aware that I can use an overload of Device.Present if I set the swap effect to copy, but this doesn't allow me to use Multi Sample Anti Alias (which requires the Discard swap effect). It seems to me that the overload Device.Present is not usable with any other swap effect than copy, and throws an exception. An other alternative I considered is the PresentFlags.DeviceClip, however it seems that it works only for Windows XP. I'm using Windows 7 and it doesn't seem to be doing anything. So, is it even possible that I use anti-aliasing in this situation?

• Devise password reset issue (new_user?)

  - by rabid_zombie

  When a user's email is inputted into the forgot password form and submitted, I am receiving an error saying login can't be blank. I looked around devise.en.yml for this error message, but can't seem to find it anywhere. Here is my views/devise/passwords/new.html.haml: %div.registration_page %h2 Forgot your password? = form_for(resource, :as => resource_name, :url => user_password_path, :html => { :method => :post, :id => 'forgot_pw_form', :class => 'forgot_pw' }) do |f| %div = f.email_field :email, :placeholder => 'Email', :autofocus => true, :autocomplete => 'off' %div.email_error.error %input.btn.btn-success{:type => 'submit', :value => 'Send Instructions'} = render "devise/shared/links" The form is posting to users/password like it should, but I noticed that my forgot password form attaches class = 'new_user'. Here is what my form displays: <form accept-charset='UTF-8' action='/users/password' class='new_user' id='forgot_pw_form' method='post' novalidate='novalidate'></form> My routes for devise (I have custom sessions and registrations controllers): devise_for :users, :controllers => {:sessions => 'sessions', :registrations => 'registrations'} How can I setup devise's forgot password functionality?

• Domain model for an online WYSYWG webpage generator / runtime

  - by CharlieBrown

  Hi all, I'm using C#, MVC, NHibernate and StructureMap as my IoC container, and need some ideas regarding my domain model. The application I'm working has two parts: an Authoring part and a Runtime part. The idea is to allow the user to create a webpage in Authoring (mostly a form actually) by choosing from a set of predefined controls. That webpage will be later used as a form in a call center environment (Runtime part), or may be used in an intranet portal, etc. Basically something similar to what a CMS would do. The difference is, of course, that the webpage/form the author generates will be used and fulfilled in runtime, and that authros should be able to freely create the webpage they want without limitations. I have a draft working model that allows a RunController to iterate over the ScriptPage (my class for the "generated webpage") Controls collection and uses partial views to render each of them. Works kind of fine. Basically I have a common ScriptControl class, and then I can create for example a TextInputControl or a DropDownControl by inheriting from that base class. I can also figure out the Authoring part of the app, although that will surely be fun in itself for sure. :) The biggest problem I have now is persistance. In order to be flexible, I want to be able to add more controls, and template controls (think of an Address composite control) in sepparate DLLs, so I think having a relational model that handles very possible control is not the way to go. My current thinking is using a kind of ObjectStore: binary-serializing the ScriptPage object that contains the List collection and deserializing at Runtime, but I'm not sure how good will it work with NHibernate and how good the performance will be. Serializing a small "page" with 10 controls results in 7964 bytes, for example. Any ideas out there? Thanks in advance, excuse the length. ;)

• Convert asp.net application to windows forms app

  - by rogdawg

  I have written and deployed an ASP.NET application that is pretty complex. It uses XSL transformations to create web forms for a large variety of data objects. The data comes from the database as XML via a web service. Now, I need to create a Windows desktop application that will provide a small subset of the web applications functionality to a user who may not have access to the web (working in remote areas). I will provide the data syncing using the MS Sync Framework. And I will have the desktop use a local data store. I would like to use the same xslt files in the desktop app that I use in the web app for the form creation so that, if changes are made, the desktop app can update itself when it connects and syncs its data. But, I am wondering how to replicate the asp.net codebehind logic of my web app in the windows forms. If I use a browser control to render the XSLTransformation result, then how could I handle click events, etc, in the form? Also, can I launch other windows as "dialog boxes" from my windows forms (I do this in my web app using RadControls functionality)? Thanks for any advice you can give.

• sending specific data into a collection partial

  - by mikeglaz

  I have a User class with a has_many :messages and a Message class which belongs_to :user. In the Message controller's show action has the corresponding view: <% if @messages.any? %> <ol class="microposts"> <%= render partial: 'shared/message', collection: @messages %> </ol> <% end %> And the shared/_message.html.erb template looks like this: <li id="<%= message.id %>"> <span class="content"><%= message.body %></span> <% user_id = message.from %> <% user = User.find(user_id) %> From: <%= user.name %> </li> I feel like the following two lines should be done in the Messages controller from what I read in tutorials on Rails: <% user_id = message.from %> <% user = User.find(user_id) %> But how would I pass each message's corresponding from value (which stores user.id) into the partial? thanks, mike

• UIBezierPath too many paths = too slow?

  - by HHHH

  I have a loop in which I'm adding many (10000+) lines to a UIBezierPath. This seems to be fine, but once I try and render the bezierpath, my device becomes extremely slow and jerky. Is this because I've added too many lines to my path? Adding lines to UIBezierPath - simplified: (this seems fine) [path moveToPoint:CGPointZero]; for (int i = 0; i < 10000; i++ ) { [path addLineToPoint:CGPointMake(i, i)]; } Rendering BeizerPath (Suggested by Rob) - this seems slow. - (void)drawBezierAnimate:(BOOL)animate { UIBezierPath *bezierPath = path; CAShapeLayer *bezier = [[CAShapeLayer alloc] init]; bezier.path = bezierPath.CGPath; bezier.strokeColor = [UIColor blueColor].CGColor; bezier.fillColor = [UIColor clearColor].CGColor; bezier.lineWidth = 2.0; bezier.strokeStart = 0.0; bezier.strokeEnd = 1.0; [self.layer addSublayer:bezier]; if (animate) { CABasicAnimation *animateStrokeEnd = [CABasicAnimation animationWithKeyPath:@"strokeEnd"]; animateStrokeEnd.duration = 100.0; animateStrokeEnd.fromValue = [NSNumber numberWithFloat:0.0f]; animateStrokeEnd.toValue = [NSNumber numberWithFloat:1.0f]; [bezier addAnimation:animateStrokeEnd forKey:@"strokeEndAnimation"]; } } Qs: 1) Is this because I'm adding too many paths too quickly? 2) I want to eventually draw many different lines of different colors, so I assume I would need to create multiple (10000+) UIBezierPaths - would this help or greatly slow the device as well? 3) How would I get around this? Thanks in advance for your help.

• What is the fastest (to access) struct-like object in Python?

  - by DNS

  I'm optimizing some code whose main bottleneck is running through and accessing a very large list of struct-like objects. Currently I'm using namedtuples, for readability. But some quick benchmarking using 'timeit' shows that this is really the wrong way to go where performance is a factor: Named tuple with a, b, c: >>> timeit("z = a.c", "from __main__ import a") 0.38655471766332994 Class using __slots__, with a, b, c: >>> timeit("z = b.c", "from __main__ import b") 0.14527461047146062 Dictionary with keys a, b, c: >>> timeit("z = c['c']", "from __main__ import c") 0.11588272541098377 Tuple with three values, using a constant key: >>> timeit("z = d[2]", "from __main__ import d") 0.11106188992948773 List with three values, using a constant key: >>> timeit("z = e[2]", "from __main__ import e") 0.086038238242508669 Tuple with three values, using a local key: >>> timeit("z = d[key]", "from __main__ import d, key") 0.11187358437882722 List with three values, using a local key: >>> timeit("z = e[key]", "from __main__ import e, key") 0.088604143037173344 First of all, is there anything about these little timeit tests that would render them invalid? I ran each several times, to make sure no random system event had thrown them off, and the results were almost identical. It would appear that dictionaries offer the best balance between performance and readability, with classes coming in second. This is unfortunate, since, for my purposes, I also need the object to be sequence-like; hence my choice of namedtuple. Lists are substantially faster, but constant keys are unmaintainable; I'd have to create a bunch of index-constants, i.e. KEY_1 = 1, KEY_2 = 2, etc. which is also not ideal. Am I stuck with these choices, or is there an alternative that I've missed?

  I'm using webview.capturePicture() to create a Picture object that contains all the drawing objects for a webpage. I can successfully render this Picture object to a bitmap using the canvas.drawPicture(picture, dst) with no problems. However when I use picture.writeToStream(fos) to serialize the picture object out to file, and then Picture.createFromStream(fis) to read the data back in and create a new picture object, the resultant bitmap when rendered as above is missing any larger images (anything over around 20KB! by observation). This occurs on all the Android OS platforms that I have tested 1.5, 1.6 and 2.1. Looking at the native code for Skia which is the underlying Android graphics library and the output file produced from the picture.writeToStream() I can see how the file format is constructed. I can see that some of the images in this Skia spool file are not being written out (the larger ones), the code that appears to be the problem is in skBitmap.cpp in the method void SkBitmap::flatten(SkFlattenableWriteBuffer& buffer) const; It writes out the bitmap fWidth, fHeight, fRowBytes, FConfig and isOpaque values but then just writes out SERIALIZE_PIXELTYPE_NONE (0). This means that the spool file does not contain any pixel information about the actual image and therefore cannot restore the picture object correctly. Effectively this renders the writeToStream and createFromStream() APIs useless as they do not reliably store and recreate the picture data. Has anybody else seen this behaviour and if so am I using the API incorrectly, can it be worked around, is there an explanation i.e. incomplete API / bug and if so are there any plans for a fix in a future release of Android? Thanks in advance.

• Password protect user image album

  - by Poland Rocks

  Hi Im making i photo sharint site I want to give the ability for my users to prevent the public to acces their albums with a password. Then they can give the password to the ones they want to be able to see it. To password protect their albums. Im thinking something like this, cant test it on this computer, should work ok. but as im a php/mysql beginner i wanna hear what you experts think if theres a better way/approach Albums id name owner password (if it isnt null the album is considered password protected) The code $id = isset($_GET['albumID']) ? intval($_GET['albumID']) : 0; $result = mysql_query("SELECT * FROM albums WHERE id = $id"); $row = mysql_fetch_object($result); // IS it password protected? if ($row->password != NULL) { echo "This album is password protected."; // User pressed "Enter" if (!empty($_POST['password'])) { $result = mysql_query("SELECT password FROM albums WHERE password = '".mysql_real_escape_string($_POST['password'])."'"); // Was It right password? if (mysql_num_rows($result) == 1) { $authed=1; } echo << <form method="post"> <input type="text" name="password" /> EOT; exit; } else $authed=1; if $authed==1 { // render albumimages etc }

• Ways to support manually executed tests? (that can be used on a Mac)

  - by Rinzwind

  Are there any tools that can be used on a Mac to support manually executed tests? I have a number of tests that I'm executing manually and which I'm currently documenting using merely a plain text file. "Tools" can be interpreted rather loosely here, anything that's a step up from the plain text file would be useful: a template for some suitable application, supporting AppleScript scripts, a web-based system, a full-blown application ... Some things that would be great to have better support for (see also the example below): Checking off each step while you're manually executing the test. Showing the next step(s) in a small window that is always kept in front of all other windows. Automatically updating the 'last tested' and 'using svn revision' info. Keeping a record of all previous testing rounds (not just the last one). ... Any suggestions for any such "tools" that can be used on a Mac? An example (faked) entry from the plain text file to give you a better idea of what I'm looking for: - Check that exported web pages render properly in Safari. Last tested: 2010-03-24 Using SVN revision: 1000 Steps: - Open a new document. - Add some items to the document. - Export the document to a web page "Test.html" in a new folder "Export Test" on the Desktop. - Open the web page in Safari, script: tell application "Finder" open file "Test.html" of folder "Export Test" of desktop end tell Expected results: - The web page should appear properly with all items shown. Clean up steps: - Remove the folder "Export Test" from the Desktop. ( Note: for those unaware, the snippet of AppleScript in the above can be executed from most text editing applications through the Services menu by selecting the snippet and using: the application menu Services Script Editor Run as AppleScript. This is quite useful to automate some steps for tests that are difficult to automate as a whole. )
