• HTML element to use as a Javascript message display

  - by javanix

  I have a message display field on my website that I'd like to change the value of via JS. I've been using just a textfield, disabling it, and modifying the value via a JS function (after using a little CSS to make it not look like a text field): <input type="text" id="message" style="background: white; color: black" size="50" disabled> There has to be a better way (for instance, formatting is tricky whenever the message runs over the specified size), but I can't think of it off the top of my head. Can anyone point me in a better direction? Thanks! FYI: I am doing a timer function which I'd like to look something like "HH:MM:SS | 'my message here'"

• CellTable + AsyncListViewAdapter<T>, stuck at 'loading' when paging

  - by Jaroslav Záruba

  Hi I'm trying to make CellTable, AsyncListViewAdapter<T> and SimplePager<T> working together. I managed to display my data, but whenever I click either "go to start" or "go to end" button I get that 'loading' indicator which stays there till the end of days. ( AsyncListViewAdapter<T>.onRangeChanged doesn't even get called this time.) As I have only single row in my data those two buttons should be (and appear to be) disabled. I went through the code-snippets in this thread, but I can't see nothing suspicions in what I've been doing. Is there some obvious answer to a rookie mistake? I shrinked my variable names, hopefully it won't wrap too much. protected class MyAsyncAdapter extends AsyncListViewAdapter<DTO> { @Override protected void onRangeChanged(ListView<DTO> v) { // doesn't get called on go2start/go2end :( Range r = v.getRange(); fetchData(r.getStart(), r.getLength()); } } private void addTable() { // table: CellTable<DTO> table = new CellTable<DTO>(10); table.addColumn(new Column<DTO, String>(new TextCell()) { @Override public String getValue(DTO namespace) { return namespace.getName(); } }, "Name"); // pager: SimplePager<DTO> pager = new SimplePager<DTO>(table); table.setPager(pager); adapter = new MyAsyncAdapter(); adapter.addView(table); // does not make any difference: // adapter.updateDataSize(0, false); // adapter.updateDataSize(10, true); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(table); vPanel.add(pager); RootLayoutPanel.get().add(vPanel); } // success-handler of my fetching AsyncCallback @Override public void onSuccess(List<DTO> data) { // AsyncCallback<List<DTO>> has start field adapter.updateViewData(start, data.size(), data); if(data.size() < length) adapter.updateDataSize(start + data.size(), true); } Regards J.

• Low cost way to host a large table yet keep the performance scalable?

  - by Leo Liang

  I have a growing table storing time series data, 500M entries now, and 200K new records every day. The total size is around 15GB for now. My clients are querying the table via a PHP script mostly, and the size of the result set is around 10K records (not very large). select * from T where timestamp > X and timestamp < Y and additionFilters And I want this operation cheap. Currently my table is hosting in Postgres 7, on a single 16G memory Box, and I would love to see some good suggestion for me to host this in low cost and also allow me to scale up for performance if needed. The table serves: 1. Query: 90% 2. Insert: 9.9% 2. Update: 0.1% <-- very rare.

• Nicely printing/showing a binary tree in Haskell

  - by nicole

  I have a tree data type: data Tree a b = Branch b (Tree a b) (Tree a b) | Leaf a ...and I need to make it an instance of Show, without using deriving. I have found that nicely displaying a little branch with two leaves is easy: instance (Show a, Show b) => Show (Tree a b) where show (Leaf x) = show x show (Branch val l r) = " " ++ show val ++ "\n" ++ show l ++ " " ++ show r But how can I extend a nice structure to a tree of arbitrary size? It seems like determining the spacing would require me to know just how many leaves will be at the very bottom (or maybe just how many leaves there are in total) so that I can allocate all the space I need there and just work 'up.' I would probably need to call a size function. I can see this being workable, but is that making it harder than it is?

• How to detect an 'image area' percentage inside an image?

  - by DaNieL

  Mhh, kinda hard to explain with my poor english ;) So, lets say I have an image, doesnt matter what kind of (gif, jpg, png) with 200x200 pixel size (total area 40000 pixels) This image have a background, that can be trasparent, or every color (but i know the background-color in advance). Lets say that in the middle of this image, there is a picture (for keep the example simple lets suppose is a square drawn), of 100x100 pixels (total area 10000 pixels). I need to know the area percentage that the small square fill inside the image. So, in i know the full image size and the background-color, there is a way in php/python to scan the image and retrieve that (in short, counting the pixel that are different from the given background)? In the above example, the result should be 25%

• Nokia aurait abandonné le développement de son Smartphone sous MeeGo et se serait allié à Microsoft

  Nokia aurait abandonné le développement de son Smartphone sous MeeGo et se serait allié à Microsoft Les rumeurs ne font que s'enchainer sur le net concernant l'avenir de l'OS mobile de Nokia MeeGo, depuis la publication d'un memo interne expédié à tous les employés de la firme par son PDG Stephen Elop. Dans ce memo le PDG de Nokia fait une comparaison extrême en présentant sa firme comme étant une entreprise sur une plate-forme pétrolière en flamme, avant de conclure que des changements radicaux de comportement doivent être effectués.

• Is there a graphical way of installing fonts in 11.10/Gnome 3

  - by appi2012

  When testing 11.10, I wanted to install some fonts. However, it seems that I cannot simply double click a font file to install it. I've tried searching google, but I haven't found anything that says the gnome3 can't do this. Is this going to be addressed? Is there a way I can install new fonts easily? (I know of the manual copying of the fonts to /usr/share/fonts/, but I'm just curious if there is something easier I've been missing.) Thanks

• I'm working on a website that sells different artwork, what's the best way to handle different image

  - by ThinkingInBits

  I'm working on a website that will allow users to upload and sell their artwork in different sizes. I was wondering what the best way would be to handle the different file sizes automatically. A few points I was curious on: How to define different size categories (small, medium, large) in such a way that I'll be able to dynamically re-size images with proportional dimensions. Should I store actual jpegs of the different sizes for download? Or would it be easier to generate these different sizes for download on the fly My thumbnails will be somewhat larger than your average thumbnails, should I store a second 'thumbnail image' with the sites watermark overlaying it? Or once again, generate this on the fly? All opinions, advice are greatly appreciated!

• Orchard shapeshifting

  - by Bertrand Le Roy

  I've shown in a previous post how to make it easier to change the layout template for specific contents or areas. But what if you want to change another shape template for specific pages, for example the main Content shape on the home page? Here's how. When we changed the layout, we had the problem that layout is created very early, so early that in fact it can't know what content is going to be rendered. For that reason, we had to rely on a filter and on the routing information to determine what layout template alternates to add. This time around, we are dealing with a content shape, a shape that is directly related to a content item. That makes things a little easier as we have access to a lot more information. What I'm going to do here is handle an event that is triggered every time a shape named "Content" is about to be displayed: public class ContentShapeProvider : IShapeTableProvider { public void Discover(ShapeTableBuilder builder) { builder.Describe("Content") .OnDisplaying(displaying => { // do stuff to the shape }); } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } This handler is implemented in a shape table provider which is where you do all shape related site-wide operations. The first thing we want to do in this event handler is check that we are on the front-end, displaying the "Detail" version, and not the "Summary" or the admin editor: if (displaying.ShapeMetadata.DisplayType == "Detail") { Now I want to provide the ability for the theme developer to provide an alternative template named "Content-HomePage.cshtml" for the home page. In order to determine if we are indeed on the home page I can look at the current site's home page property, which for the default home page provider contains the home page item's id at the end after a semicolon. Compare that with the content item id for the shape we are looking at and you can know if that's the homepage content item. Please note that if that content is also displayed on another page than the home page it will also get the alternate: we are altering at the shape level and not at the URL/routing level like we did with the layout. ContentItem contentItem = displaying.Shape.ContentItem; if (_workContextAccessor.GetContext().CurrentSite .HomePage.EndsWith(';' + contentItem.Id.ToString())) { _workContextAccessor is an injected instance of IWorkContextAccessor from which we can get the current site and its home page. Finally, once we've determined that we are in the specific conditions that we want to alter, we can add the alternate: displaying.ShapeMetadata.Alternates.Add("Content__HomePage"); And that's it really. Here's the full code for the shape provider that I added to a custom theme (but it could really live in any module or theme): using Orchard; using Orchard.ContentManagement; using Orchard.DisplayManagement.Descriptors; namespace CustomLayoutMachine.ShapeProviders { public class ContentShapeProvider : IShapeTableProvider { private readonly IWorkContextAccessor _workContextAccessor; public ContentShapeProvider( IWorkContextAccessor workContextAccessor) { _workContextAccessor = workContextAccessor; } public void Discover(ShapeTableBuilder builder) { builder.Describe("Content") .OnDisplaying(displaying => { if (displaying.ShapeMetadata.DisplayType == "Detail") { ContentItem contentItem = displaying.Shape.ContentItem; if (_workContextAccessor.GetContext() .CurrentSite.HomePage.EndsWith( ';' + contentItem.Id.ToString())) { displaying.ShapeMetadata.Alternates.Add( "Content__HomePage"); } } }); } } } The code for the custom theme, with layout and content alternates, can be downloaded from the following link: Orchard.Themes.CustomLayoutMachine.1.0.nupkg Note: this code is going to be used in the Contoso theme that should be available soon from the theme gallery.

• Microsoft Unveils New Logo

  Indeed, with those four familiar colored squares - set in a bigger square rather than standing on a point in a diamond - Microsoft's new corporate logo seems almost inevitable. As you'd expect, the company's name makes up part of the logo, but instead of the thick italic letters it has used for the past two and a half decades, it's in a more standard, lighter font. Jeff Hansen, Microsoft's general manager of brand strategy, notes that the point of the new logo is to signal the heritage but also signal the future - a newness and a freshness. It's very fitting when you consider just how many...

• How to sort some values from an array in a controller in Rails?

  - by Alfred Nerstu

  I've got a links array that I'm saving to a database. The problem is that the records aren't saved in the order of the array ie links[1] is saved before links[2] and so on... This is a example from the view file: <p> <label for="links_9_label">Label</label> <input id="links_9_name" name="links[9][name]" size="30" type="text" /> <input id="links_9_url" name="links[9][url]" size="30" type="text" /> </p> And this is my controller: def create @links = params[:links].values.collect { |link| @user.links.new(link) } respond_to do |format| if @links.all?(&:valid?) @links.each(&:save!) flash[:notice] = 'Links were successfully created.' format.html { redirect_to(links_url) } else format.html { render :action => "new" } end end end Thanks in advance!

• how to check if internal storage file has any data

• Does a program exist for checking two similar directories for file differences?

  - by John Sullivan

  Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories.

• Something like a manual refresh is needed angularjs, and a $digest() iterations error

  - by Tony Ennis

  (post edited again, new comments follow this line) I'm changing the title of this posting since it was misleading - I was trying to fix a symptom. I was unable to figure out why the code was breaking with a $digest() iterations error. A plunk of my code worked fine. I was totally stuck, so I decided to make my code a little more Angular-like. One anti-pattern I had implemented was to hide my model behind my controller by adding getters/setters to the controller. I tore all that out and instead put the model into the $scope since I had read that was proper Angular. To my surprise, the $digest() iterations error went away. I do not exactly know why and I do not have the intestinal fortitude to put the old code back and figure it out. I surmise that by involving the controller in the get/put of the data I added a dependency under the hood. I do not understand it. edit #2 ends here. (post edited, see EDIT below) I was working through my first Error: 10 $digest() iterations reached. Aborting! error today. I solved it this way: <div ng-init="lineItems = ctrl.getLineItems()"> <tr ng-repeat="r in lineItems"> <td>{{r.text}}</td> <td>...</td> <td>{{r.price | currency}}</td> </tr </div> Now a new issue has arisen - the line items I'm producing can be modified by another control on the page. It's a text box for a promo code. The promo code adds a discount to the lineItem array. It would show up if I could ng-repeat over ctrl.getLineItems(). Since the ng-repeat is looking at a static variable, not the actual model, it doesn't see that the real line items have changed and thus the promotional discount doesn't get displayed until I refresh the browser. Here's the HTML for the promo code: <input type="text" name="promo" ng-model="ctrl.promoCode"/> <button ng-click="ctrl.applyPromoCode()">apply promo code</button> The input tag is writing the value to the model. The bg-click in the button is invoking a function that will apply the code. This could change the data behind the lineItems. I have been advised to use $scope.apply(...). However, since this is applied as a matter of course by ng-click is isn't going to do anything. Indeed, if I add it to ctrl.applyPromoCode(), I get an error since an .apply() is already in progress. I'm at a loss. EDIT The issue above is probably the result of me fixing of symptom, not a problem. Here is the original HTML that was dying with the 10 $digest() iterations error. <table> <tr ng-repeat="r in ctrl.getLineItems()"> <td>{{r.text}}</td> <td>...</td> <td>{{r.price | currency}}</td> </tr> </table> The ctrl.getLineItems() function doesn't do much but invoke a model. I decided to keep the model out of the HTML as much as I could. this.getLineItems = function() { var total = 0; this.lineItems = []; this.lineItems.push({text:"Your quilt will be "+sizes[this.size].block_size+" squares", price:sizes[this.size].price}); total = sizes[this.size].price; this.lineItems.push({text: threads[this.thread].narrative, price:threads[this.thread].price}); total = total + threads[this.thread].price; if (this.sashing) { this.lineItems.push({text:"Add sashing", price: this.getSashingPrice()}); total = total + sizes[this.size].sashing; } else { this.lineItems.push({text:"No sashing", price:0}); } if(isNaN(this.promo)) { this.lineItems.push({text:"No promo code", price:0}); } else { this.lineItems.push({text:"Promo code", price: promos[this.promo].price}); total = total + promos[this.promo].price; } this.lineItems.push({text:"Shipping", price:this.shipping}); total = total + this.shipping; this.lineItems.push({text:"Order Total", price:total}); return this.lineItems; }; And the model code assembled an array of objects based upon the items selected. I'll abbreviate the class as it croaks as long as the array has a row. function OrderModel() { this.lineItems = []; // Result of the lineItems call ... this.getLineItems = function() { var total = 0; this.lineItems = []; ... this.lineItems.push({text:"Order Total", price:total}); return this.lineItems; }; }

• C# socket blocking behavior

  - by Gearoid Murphy

  My situation is this : I have a C# tcp socket through which I receive structured messages consisting of a 3 byte header and a variable size payload. The tcp data is routed through a network of tunnels and is occasionally susceptible to fragmentation. The solution to this is to perform a blocking read of 3 bytes for the header and a blocking read of N bytes for the variable size payload (the value of N is in the header). The problem I'm experiencing is that occasionally, the blocking receive operation returns a partial packet. That is, it reads a volume of bytes less than the number I explicitly set in the receive call. After some debugging, it appears that the number of bytes it returns is equal to the number of bytes in the Available property of the socket before the receive op. This behavior is contrary to my expectation. If the socket is blocking and I explicitly set the number of bytes to receive, shouldn't the socket block until it recv's those bytes?, any help, pointers, etc would be much appreciated.

• Best way to model map values in Grails?

  - by Mulone

  Hi guys, I have to implement map values in my Grails app. I have a class that can contain 0..N OsmTags, and the key is unique. In Java I would model this with a Map in each object, but I don't know how to map classes in Grails. So I defined this class: class OsmTag { /** OSM tag name, e.g. natural */ String key /** OSM tag value, e.g. park */ String value static constraints = { key blank:false, size:2..80,matches:/[\S]+/, unique:false value blank:false, size:1..250,matches:/[\S]+/, unique:false } } That works ok, but it's actually quite ugly because the tag key is not unique. Is there a better way to model this issue? Cheers

Unfortunately once I open the PDF with a texteditor some lines doesn't make sense... just like.... %PDF-1.6 %âãÏÓ 3 0 obj <</Ff 0/F 6/Type/Annot/Subtype/Widget/DR<</Font<</Helv 2 0 R>>>>/T(Ä\n¬4^XÈ4ýæçO§W²W^D³^Ywzº<92>õÌ^AÀÄi]â<96><8c>)/V(Ä\n¬4^XÈ4ýæçO§W²W^Dø<93>r^D¥à<82>ú<83>Z^Q7^Cv^FÈ)/AP<</N 1 0 R>>/P 4 0 R/BS<</W 1/S/S>>/FT/Tx/Rect[40 50 70 80]/DA(Ä\n¬4^XÈ4ýæçO§W²W^Dù~êw3<84>&^X´âL|q@³^VC<8a>"Ýo^N¿=Ì<91>ta^R`àz)>> endobj 6 0 obj so %PDF-1.6 is fine but after it s not resolving the correct letters.... I tried with vim ... is there any chance to get the correct content ....

• MATLAB plot moving data points in seperate subplots simutaneously

  - by Nate B.

  I wish to visualize the movement of a data point throughout space across a period of time within MATLAB. However, the way I want my figure to display is such that only a single instant is plotted at any given time. That was easy, I simply created a for loop to update my 3D plot display for every set of coordinates (x,y,z) in my data. However, I wish to display 4 different viewing angles of this plot at all times. I am well aware of how to setup subplots within MATLAB, that is not the issue. My issue is getting all 4 of these subplots to execute simultaneously so that all 4 subplots are always displaying the same point in time. I would appreciate if anyone could suggest how to handle this issue. As requested, my code for a figure with a single plot is shown below: datan = DATA; %data in form of x,y,z,a,b,c by column for row# of time points tib=zeros(size(datan,1),12); tib(:,1:3) = datan(:,1:3); tib_ref=tib(1,1:3); for i=1:size(datan,1) tib(i,1:3)=tib(i,1:3)-tib_ref; end angle_to_dircos close all figure('Name','Directions (Individual Cycles)','NumberTitle','off') for cc=1:2 hold off for bb=1:10:size(tib,1); scatter3(tib(bb,1),tib(bb,2),tib(bb,3),'green','filled'); %z and y axes are flipped in polhemus system hold on p0 = [tib(bb,1),tib(bb,2),tib(bb,3)]; p1 = [tib(bb,1)+10*tib(bb,4),tib(bb,2)+10*tib(bb,5),tib(bb,3)+10*tib(bb,6)]; p2 = [tib(bb,1)+10*tib(bb,7),tib(bb,2)+10*tib(bb,8),tib(bb,3)+10*tib(bb,9)]; p3 = [-(tib(bb,1)+100*tib(bb,10)),-(tib(bb,2)+100*tib(bb,11)),-(tib(bb,3)+100*tib(bb,12))]; vectarrow(p0,p1,1,0,0) hold on vectarrow(p0,p2,0,1,0) hold on vectarrow(p0,p3,0,0,1) hold on az = 90; el = 0; view(az, el); xlim([-50,50]); ylim([-50,50]); zlim([-50,50]); xlabel('distance from center in X'); ylabel('distance from center in Y'); zlabel('distance from center in Z'); title('XYZ Scatter Plots of Tracker Position'); hold on plot3(0,0,0,'sk','markerfacecolor',[0,0,0]); p0 = [0,0,0]; p1 = [10,0,0]; p2 = [0,10,0]; p3 = [0,0,100]; vectarrow(p0,p1,1,0,0) hold on vectarrow(p0,p2,0,1,0) hold on vectarrow(p0,p3,1,0,1) drawnow; end end

• Overriding constructors

  - by demas

  Here is sample code: class One def initialize(*args) case args.size when 0 puts "one initialize" when 1 puts "one initialize #{args[0]}" end end end class Two def initialize(*args) if args.size == 2 then puts "two initialize #{args[0]} and #{args[1]}" else super(args) end end end one = One.new one = One.new("thing") two = Two.new("some", "other") two = Two.new("some") Now I'm launching the code and getting the error message: [[email protected]][~/temp]% ruby test2.rb one initialize one initialize thing two initialize some and other test2.rb:17:in `initialize': wrong number of arguments(1 for 0) (ArgumentError) from test2.rb:17:in `initialize' from test2.rb:26:in `new' from test2.rb:26:in `<main>' How can I call parent's constructor from class Two ?

• read http header info in ASIHttpRequest asynchronous

  - by user262325

  Hello everyone One of my project is to download several large size files using ASIHTTPRequest in asynchronous mode. I hope to read the http returned header info to get the size of files. I know [request respsonseHeaders] (requestFinished: delegate method ) can do that. I tested and found that requestFinished: is only triggered when it completed the download of a whole single file. But I hope to access the function [request respsonseHeaders] before ASIHTTPRequest starting to download files (just when ASIHTTPRequest got the returned header info). I can not find the triggered event for this. Welcome any comment Thanks interdev

• How can I shift html-text in the JButton to the left?

  - by Roman

  I use HTML to put text into a JButton. In this way I can play with colors and text size. What I do not like is the distance from the left border of the button and the text (this separation is too large). Is there a way to decrease this distance? I think it should be some parameter in the style of the HTML code. Sample of the code: JButton btn = new JButton("<html><span style='color:#000000; font-size: 11pt;'>" + label + "</span></html>");
