  • Cookie access within a HTTP Class

    - by James Jeffery
    I have a HTTP class that has a Get, and Post, method. It's a simple class I created to encapsulate Post and Get requests so I don't have to repeat the get/post code throughout the application. In C#: class HTTP { private CookieContainer cookieJar; private String userAgent = "..."; public HTTP() { this.cookieJar = new CookieContainer(); } public String get(String url) { // Make get request. Return the JSON } public String post(String url, String postData) { // Make post request. Return the JSON } } I've made the CookieJar a property because I want to preserve the cookie values throughout the session. If the user is logged into Twitter with my application, each request I make (be it get or post) I want to use the cookies so they remain logged in. That's the basics of it anyway. But, I don't want to return a string in all instances. Sometimes I may want the cookie, or a header value, or something else from the request. Ideally I'd like to be able to do this in my code: Cookie cookie = http.get("http://google.com").cookie("g_user"); String g_user = cookie.value; or String source = http.get("http://google.com").body; My question - To do this, would I need to have a Get class, and a Post class, that are included within the HTTP class and are accessible via accessors? Within the Get and Post class I would then have the Cookie method, and the body property, and whatever else is needed. Should I also use an interface, or create a Request class and have Post and Get extend it so that common methods and properties are available to both classes? Or, am I thinking totally wrong?

  • How do I change the date format in Gnome 3 shell?

    - by James Haigh
    I want to change the date/time format on the top panel to a format close to RFC 3339 / ISO 8601, like one of these: %F %T ? 2013-06-24 16:13:00 %F %a %T ? 2013-06-24 Mon 16:13:00 %A %F %T ? Monday 2013-06-24 16:13:00 I know Unity has a preference somewhere hidden away in dconf, this is how I did it in Unity, but I can't find such a preference for Gnome 3 shell. Preferably, I'd also like to set one of these as my system-wide date/time locale preference.

  • Influence Maps for Pathfinding?

    - by james
    I'm taking the plunge and am getting into game dev, it's been going well but I've got stuck on a problem. I have a maze that is 100x100 with 0,1 to indicate if its a path or a wall. Within the maze I have 300 or so enemies and a player. The outcome I'm looking for is all the enemies work their way towards the player position. Originally I did this using an A* path finding algorithm but with 300 enemies it was taking forever to path find each one individually. After some research I found that an influence map / collaborative diffusion would be the best way to go. But I'm having a real hard time working out how this is actually done. Firstly.. How do you create a influence map? From what I understand each of my walls with have a scent of 0 so that makes them impassable.. then basically a radial effect from my player position to each other cell (So my player starts at 100 and then going outwards from that each other cell will be reduced value) Is that correct? If so,.. How would you do that (Math magic?) My next problem is if that is correct how would my "enemies" stop from getting stuck if they have gone down the wrong way? As say if my player was standing on the otherside of a wall if the enemy is just looking for larger numbers wont it keep getting stuck? I'm doing this in JavaScript so performance is key. Thanks for any help! EDIT: Or if anyones got a better solution? I've been reading about navmeshs, steering pathing, pre calculating all paths on load etc etc

  • JQuery Validation dates [migrated]

    - by james
    Im trying to get my form to validate...so basically its working, but a little bit too well, I have two text boxes, one is a start date, the other an end date in the format of mm/dd/yyyy if the start date is greater than the end date...there is an error if the end date is less than the start date...there is an error if the start date is less than today's date...there is an error The only thing is when I correct the error, the error warning is still there...here is my code: // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else { if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } and here are the two text boxes: <div id="campaign_start" style="display: inline-block"> <label class="date_range_label">from:</label> <asp:TextBox ID="FromCalTbx" runat="server" Width="100px" CssClass="FromCal editable float_left required" /> </div> <div id="campaign_end" style="display: inline-block"> <label class="date_range_label">to:</label> <asp:TextBox ID="ToCalTbx" runat="server" Width="100px" CssClass="float_left optional"/> </div> PS - testDate is the start Date otherDate is the end Date

  • Ways to prevent client seeing my code

    - by James Eggers
    I've got a bit of a strange problem.. Basically, I'm building a fairly complex (un-compiled, interpreted) program in Python. I've been working on most of this code for other purposes for a few months, and therefore don't want my client to be able to simple copy and paste it and then try and sell it (it's worth a fair amount). The other problem is that I need the script to run on a server that my client is paying for. Is there any way I can secure a particular folder on the machine from root access, make it so only one particular can access the directory? The OS is Ubuntu.

  • On installing nvidia drivers on 12.10 I get "Bad return status for module build on kernel: 3.5.0-19-generic (x86_64)"

    - by james
    New Ubuntu user - just recently made the mistake of trying a different nvidia driver. I'd managed to get the last (nvidia-current) one working through software sources a few weeks ago. The other day I tried to cross over to nvidia-experimental-310 and this produced a system error. Swapping back and forth between proprietary drivers now always causes an error and I can't get any of them to work. Installing through the terminal I get this error message every time: Building initial module for 3.5.0-19-generic Error! Bad return status for module build on kernel: 3.5.0-19-generic (x86_64) Consult /var/lib/dkms/nvidia-experimental-310/310.14/build/make.log for more information On rebooting, I end up with the crappy screen resolution and the thick black border around the screen. I use gksudo software-properties-gtk to bring up sources, where I can change back to the nouveau driver, which restores my screen. After that I can't find /var/lib/dkms/nvidia-experimental-310/310.14/build/make.log so I can't tell you what's inside. Any ideas what might be preventing the nvidia driver from installing? SOLUTION FOUND Okay - so I have a workaround. This is what has worked: Upgrade to kernel 3.7.0 as detailed here upgrade to latest version of the nvidia drivers as detailed here No idea what was happening with kernel 3.5.0-19, but this seems to be better. A little slower maybe on boot, but after days of messing around it's nice to have something that works.

  • Is it OK to create all primary partitions.?

    - by james
    I have a 320GB hard disk. I only use either ubuntu or kubuntu (12.04 for now). I don't want to use windows or any other dual boot os. And i need only 3 partitions on my hard disk. One for the OS and remaining two for data storage. I don't want to create swap also. Now can i create all primary partitions on the hard disk. Are there any disadvantages in doing so. If all the partitions are primary i think i can easily resize partitions in future. On second thought i have the idea of using seperate partition for /home. Is it good practice . If i have to do this, i will create 4 partitions all primary. In any case i don't want to create more than 4 partitions . And i know the limit will be 4. So is it safe to create all 3 or 4 primary partitions. Pls suggest me, What are the good practices . (previously i used win-xp and win-7 on dual boot with 2 primary partitions and that bugged me somehow i don't remember. Since then i felt there should be only one primary partition in a hard disk.) EDIT 1 : Now i will use four partitions in the sequence - / , /home , /for-data , /swap . I have another question. Does a partition need continuous blocks on the disk. I mean if i want to resize partitions later, can i add space from sda3 to sda1. Is it possible and is it safe to do ?

  • How to test whether an image is already in cache? [migrated]

    - by Evik James
    I am developing a web site that has a lot of large, high-quality images on the home page. On the home page, there is an image carousel that pulls ten high quality images from a database. The images can be 1 meg each. The carousel images aren't my problem (right now), but it has something to do with it. The problem I am trying to address right now is that I use a high quality background image that I want to continue using, it's about 180k. If I have the background in cache on the home page, I want to use it. If not, then I don't want to use it on the home page. I'll load it from a different page. When the user returns to the home page, and the background image is in cache, I want to use it. Can I test whether an image is already in cache and if so, dynamically load or NOT load based on that? You can see the home page here: http://flyingpiston2012-com.securec37.ezhostingserver.com/

  • What technology(s)would be suitable for the front end part of a Java web game?

    - by James.Elsey
    As asked in a previous question, I'm looking to create a small MMO that will be deployed onto GAE. I'm confused about what technologies I could use for the user interface, I've considered the following JSP Pages - I've got experience with JSP/JSTL and I would find this easy to work with, it would require the user having to "submit" the page each time they perform an action so may become a little clumsey for players. Applet - I could create an applet that sits on the front end and communicates to the back end game engine, however I'm not sure how good this method would be and have not used applets since university.. What other options do I have? I don't have any experience in Flash/Flex so there would be a big learning curve there. Are there any other Java based options I may be able to use? My game will be text based, I may use some images, but I'm not intending to have any animations/graphics etc Thanks

  • Is the structure of my site's navigation (via price/service tables) considered 'Duplicate Content' by Google?

    - by James Gadsby
    As I'm building my business website, I'm using service/price tables at the bottom of each service page to demonstrate to customers/potential clients my other offerings. Of course, given that there are 7 or 8 service pages, each with (according to Google) the same service descriptions below the original content for that service, would this be counting as duplicate content? If so, what could I do about it?

  • Stuck with Regular Expression code to apply HTML tag to text but exclude if inside <?> tag

    - by James Buckingham
    Hi there. I'm trying to write a bit of regex which would go through some text, written by our Editors, and apply an <acronym> tag to the first instance it finds of an abbreviation set we hold in our "Glossary of Terms". So for this example I've used the abbreviation ITS. 1st thing I thought I'd do is setup an example with a mix of scenerios I could test against, i.e. ITS sitting with punctuation, in HTML tags & ones that we've applied this to already (in other words the script has run through this before, so no need to do again). I'm almost there but just got stuck at the last point :-(. Here's the regex I've got so far - <[^<|]+?>?>ITS<[^<]+?>|ITS The Example - FROM ( EVERY ITS IN BOLD TO BE WRAPPED WITH ACRONYM ): I want you to tag thisITS, but not this wrapped one - <acronym title="ITS" id="thisIsATest">ITS</acronym> This is another test as I still want to update <p>ITS</p> that have other HTML tags wrapped around them.` ITS want ones that start sentences and ones that finish ITS. ITS, and ones which are wrapped in punctuation.` Test link: <a href="index.cfm>ITS</a> AND I WANT THIS CHANGE TO : I want you to tag this <acronym title="ITS">ITS</acronym>, but not this wrapped one - <acronym title="ITS">ITS</acronym> This is another test as I still want to update <acronym title="ITS">ITS</acronym> that have other HTML tags wrapped around them.` <acronym title="ITS">ITS</acronym> want ones that start sentences and ones that finish <acronym title="ITS">ITS</acronym>. <acronym title="ITS">ITS</acronym>, and ones which are wrapped in punctuation. Test link: <acronym title="ITS"><a href="index.cfm>ITS</a></acronym> Are there any Reg Ex experts out there that could help me finish this off? Any other hints tips would also be appreciated. Thanks a lot, James P.S. This is going to be placed in a ColdFusion application if that helps anyone in specific syntax.

  • GWT combobox not displaying correctly

    - by James
    Hi, I am using GWT with GWT-EXT running in glassfish. I create 2 combo boxes as follows: import com.extjs.gxt.ui.client.widget.form.ComboBox; import com.extjs.gxt.ui.client.widget.form.SimpleComboBox; this.contentPanel = new ContentPanel(); this.contentPanel.setFrame(true); this.contentPanel.setSize((int)(Window.getClientWidth()*0.95), 600); this.contentPanel.setLayout(new FitLayout()); initWidget(this.contentPanel); SimpleComboBox<String> combo = new SimpleComboBox<String>(); combo.setEmptyText("Select a topic..."); combo.add("String1"); combo.add("String2"); this.contentPanel.add(combo); ComboBox combo1 = new ComboBox(); combo1.setEmptyText("Select a topic..."); ListStore topics = new ListStore(); topics.add("String3"); topics.add("String4"); combo.setStore(topics); this.contentPanel.add(combo1); When these are loaded in the browser (IE 8.0, Firefox 3.6.6 or Chrome 10.0) the combo boxes are shown but don't have the pull down arrow. They look like a text field with the "Select a topic..." text. When you select the text it disappears and if you type a character and then delete it the options are shown (i.e. pull down is invoked) however, there is still no pull down arrow. Does anyone know what the issue might be? Or how I can investigate further? Is it possible to see the actual HTML the browser is getting, when I View Page Source I only get the landing page HTML. As an additional I also have a import com.google.gwt.user.client.ui.Grid that does not render correctly. It is in table format but has no grid lines or header bar etc. Cheers, James

  • Issue accessing class variable from thread.

    - by James
    Hello, The code below is meant to take an arraylist of product objects as an input, spun thread for each product(and add the product to the arraylist 'products'), check product image(product.imageURL) availability, remove the products without images(remove the product from the arraylist 'products'), and return an arraylist of products with image available. package com.catgen.thread; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import com.catgen.Product; import com.catgen.Utils; public class ProductFilterThread extends Thread{ private Product product; private List<Product> products = new ArrayList<Product>(); public ProductFilterThread(){ } public ProductFilterThread(Product product){ this.product = product; } public synchronized void addProduct(Product product){ System.out.println("Before add: "+getProducts().size()); getProducts().add(product); System.out.println("After add: "+getProducts().size()); } public synchronized void removeProduct(Product product){ System.out.println("Before rem: "+getProducts().size()); getProducts().remove(product); System.out.println("After rem: "+getProducts().size()); } public synchronized List<Product> getProducts(){ return this.products; } public synchronized void setProducts(List<Product> products){ this.products = products; } public void run(){ boolean imageExists = Utils.fileExists(this.product.ImageURL); if(!imageExists){ System.out.println(this.product.ImageURL); removeProduct(this.product); } } public List<Product> getProductsWithImageOnly(List<Product> products){ ProductFilterThread pft = null; try{ List<ProductFilterThread> threads = new ArrayList<ProductFilterThread>(); for(Product product: products){ pft = new ProductFilterThread(product); addProduct(product); pft.start(); threads.add(pft); } Iterator<ProductFilterThread> threadsIter = threads.iterator(); while(threadsIter.hasNext()){ ProductFilterThread thread = threadsIter.next(); thread.join(); } }catch(Exception e){ e.printStackTrace(); } System.out.println("Total returned products = "+getProducts().size()); return getProducts(); } } Calling statement: displayProducts = new ProductFilterThread().getProductsWithImageOnly(displayProducts); Here, when addProduct(product) is called from within getProductsWithImageOnly(), getProducts() returns the list of products, but that's not the case(no products are returned) when the method removeProduct() is called by a thread, because of which the products without images are never removed. As a result, all the products are returned by the module whether or not the contained products have images. What can be the problem here? Thanks in advance. James.

  • The Java Community Process: What's Broken and How to Fix It

    - by Tori Wieldt
    In a panel discussion today at TheServerSide Java Symposium, Patrick Curran, Head of the Java Community Process, James Gosling, and ?Reza Rahman, member, Java EE 6 and EJB 3.1 expert groups, discussed the state of the JCP. Moderated by Cameron McKenzie, Editor of TheServerSide.com, they discussed what's wrong with JCP and ways to fix it.What's wrong with the JCP? Reza Rahman was quite supportive of the JCP. "I work as a consultant, and it's much better than getting a decision made a large company," Reza commented. He gave the JCP "Five stars" and explained that as an individual, he was able to have an impact on things that mattered to him. Cameron asked, "Now all these JCP problems came after Oracle acquired Sun, right?" To which the crowd had a good laugh, and the panel all agreed many of the JCP problems existed under Sun. How is the JCP handled differently under Oracle than Sun? "Pretty similar," said James. Oracle "tends more towards practicality" said Reza. "I'm glad to see things moving again, we've got several new JSRs filed," Patrick commented.How to Fix It?They all agreed greater transparency is a top issue. Without it, people assume sinister behavior whether it's there or not. Patrick said that currently spec leads are "encouraged" to be transparent, and the JCP office is planning to submit JSRs to change the JCP process so transparency is mandated, both for mailing lists and issue tracking. Shining a light on problems is the best way to fix them.Reza said the biggest problem is lack of a participation from the community. If more people are involved, a lot of the problems go away. "Developers are too non-chalant, they should realize what happens in the JCP has an direct impact on their career and they need to get involved." Reza commented.Got Involved!During Q&A, someone asked how a developer could get involved. They answered: Pick a JSR you are interested in and follow it. To start, you could read an article about the JSR and comment on the article (expert group members do read the comments). Or read the spec, discuss it with others and post a blog about it. Read the Expert Group proceedings. Join the JCP (free for individuals). Open source projects have code that you can download and play with, download it and provide feedback. Patrick mentioned that the JCP really wants more participation. "One way we are working on it is that we are encouraging JUGs to join the JCP as a group, and that makes all members of the JUG JCP members," Patrick said.They commented that most spec leads are desperate for feedback. "And, please get involved BEFORE the spec is finalized!" James declared. Someone from the audience said it's hard to put valuable time into something before it's baked. Patrick explained that Post Final Draft (PFD) is the time in the JCP process when the spec is mature enough to review but before the spec is finalized. The panel agreed the worst thing that could happen is that most people in the Java community just complain about the JCP without getting involved. Developer Sumit Goyal, conference attendee, thought it was a healthy discussion. "I got insights into how JSRs are worked on and finalized," he said.Key LinksThe Java Community Process Website  http://jcp.org/en/home/indexArticle: A Conversation with JCP Chair Patrick Curran Oracle Technology Network http://www.oracle.com/technetwork/java/index.htmlTheServerSide Java Symposium  http://javasymposium.techtarget.com/

  • WPF TreeView databinding to hide/show expand/collapse icon

    - by Julian Lettner
    I implemented a WPF load-on-demand treeview like described in this (very good) article. In the mentioned solution a dummy element is used to preserve the expand + icon / treeview item behavior. The dummy item is replaced with real data, when the user clicks on the expander. I want to refine the model by adding a property public bool HasChildren { get { ... } } to my backing TreeNodeViewModel. Question: How can I bind this property to hide/show the expand icon (in XAML)? I am not able to find a suitable trigger/setter combination. (INotifyPropertyChanged is properly implemented.) Thanks for your time. Update 1: I want to use my property public bool HasChildren instead of using the dummy element. Determining whether or not an item has children is somewhat costly, but still much cheaper than fetching the children.

  • WPF: Filter TreeView without collapsing it's nodes

    - by Julian Lettner
    This one is a follow-up question. I filter the top level nodes of a TreeView control like shown below. private void ApplyFilterHandler(object sender, RoutedEventArgs e) { if (_filterCheckBox.IsChecked.Value) CollectionViewSource.GetDefaultView(TopLevelNodes).Filter += MyFilter; else CollectionViewSource.GetDefaultView(TopLevelNodes).Filter -= MyFilter; } . <TreeView ItemsSource="{Binding TopLevelNodes}"> ... </TreeView> When the user applies the filter all nodes get collapsed. Question How can I hide certain nodes in a tree while retaining the expand state of the other nodes? Can someone explain, what happens internally on ICollectionView.Filter += MyFilter. Thanks for your time.

  • How do I pass a custom field to a hook (Invision Power Board [ipb] / PHP)

    - by Julian Young
    A long shot but here's hoping someone has some experience coding PHP hooks for Invisions Power Board forum. I'm attempting to code a status addition and the PHP works fine on it's own, it's the passing of the IPB's reference to my hook that is the issue. I.E. You setup a custom field in your forum for MSN Username, then from within a skin / template hook you pass the custom field to the hook and then use your PHP code to check on the status. Here is the IPB skin code I am hooking into on Global-userInfoPane... <if test="authorcfields:|:$author['custom_fields'] != """> <foreach loop="customFieldsOuter:$author['custom_fields'] as $group => $data"> <foreach loop="customFields:$author['custom_fields'][ $group ] as $field"> <if test="$field != ''"> <li> {$field} </li> </if> </foreach> </foreach> </if> Although I could easily add my own skin hook here. i.e. <if test="myHookHere:|:1===1"></if> Literally all I need is a single custom field entry from here passed to my hook. If I query every member when the hook is run then that will result in many extra sql queries per page view. All I want to do is pass that specific custom field to the hook... i.e. myHookHere( $customfield['msn_username'] ) Is this possible? How do you reference the customfield? Can I execute pure PHP from here? Appreciate anyone that can help! I tried the official invision forums but not had much luck.

  • Android - Views in Custom Compound Component are not inflated (findByView returns null)

When i try to find the views inside the custom compound, findViewById returns null.

  • Fade out when user leaves page — jquery

    I have some simple page transitions that fade in, once the user has landed. However, I'm also trying to make the same page fade out, when the user leaves. I have found a few solutions, but they appeared to use delay(). Are there any that don't? Thanks for any help, (I'm new to this, mind!) Tom :) I am currently using this code: $(document).ready( function(){ $( 'body' ).fadeIn(2000); $('#stop').click(function (e) { e.preventDefault(); }); $('#clients').click(function() { $("#projectinfo").slideUp('slow'); $("#us").fadeOut('slow'); $("ul").fadeToggle('slow'); }); $('#information').click(function() { $("#projectinfo").slideUp('slow'); $("ul").fadeOut('slow'); $("#us").fadeToggle('slow'); }); $('#question').click(function() { $("#projectinfo").slideToggle('slow'); }); $('#question').hover(function() { $("#projectinfo").slideToggle('slow'); }); $("a").click(function(event){ event.preventDefault(); linkLocation = this.href; $("body").fadeOut(1000, redirectPage); }); function redirectPage() { });

  • WPF: Binding to ObservableCollection in ControlTemplate is not updated

    - by Julian Lettner
    I created a ControlTemplate for my custom control MyControl. MyControl derives from System.Windows.Controls.Control and defines the following property public ObservableCollection<MyControl> Children{ get; protected set; }. To display the nested child controls I am using an ItemsControl (StackPanel) which is surrounded by a GroupBox. If there are no child controls, I want to hide the GroupBox. Everything works fine on application startup: The group box and child controls are shown if the Children property initially contained at least one element. In the other case it is hidden. The problem starts when the user adds a child control to an empty collection. The GroupBox's visibility is still collapsed. The same problem occurs when the last child control is removed from the collection. The GroupBox is still visible. Another symptom is that the HideEmptyEnumerationConverter converter does not get called. Adding/removing child controls to non empty collections works as expected. Whats wrong with the following binding? Obviously it works once but does not get updated, although the collection I am binding to is of type ObservableCollection. <!-- Converter for hiding empty enumerations --> <Common:HideEmptyEnumerationConverter x:Key="hideEmptyEnumerationConverter"/> <!--- ... ---> <ControlTemplate TargetType="{x:Type MyControl}"> <!-- ... other stuff that works ... --> <!-- Child components --> <GroupBox Header="Children" Visibility="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Children, Converter={StaticResource hideEmptyEnumerationConverter}}"> <ItemsControl ItemsSource="{TemplateBinding Children}"/> </GroupBox> </ControlTemplate> . [ValueConversion(typeof (IEnumerable), typeof (Visibility))] public class HideEmptyEnumerationConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { int itemCount = ((IEnumerable) value).Cast<object>().Count(); return itemCount == 0 ? Visibility.Collapsed : Visibility.Visible; } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } #endregion } Another, more general question: How do you guys debug bindings? Found this (http://bea.stollnitz.com/blog/?p=52) but still I find it very hard to do. I am glad for any help or suggestion.

  • How to create a Turing machine that takes a single digit decimal number from 0 - 9 and output the cu

    - by Julian
    I'm working on a project for a Turning machine but having problems conceptualizing the steps. f(x) = x^3, where x is a single digit between 0 - 9 inclusive. Based on my understanding I am to convert the number to binary but how do I find the cube of a number in binary. Also, how do I write the cube on the tape. So far I'm thinking I should create a state diagram that accepts the binary versions of 0-9 but what next?
