  • Hard Drive Light Emulator

    - by ProfKaos
    I've just got a new Dell Inspiron, and I'm a little disconcerted without the reassurance of a flashing hard drive light, especially with long installs. Is there something that can reveal HDD activity onscreen, e.g. in the system tray?

  • Handling JSON and HTML templates in jQuery

    - by Toby Hede
    I have an ajax-enabled site that presents a lot of dynamic content by interpolating JSON values with HTML. This all works fine. BUT it means I have significant amounts of HTML all through my JavaScript. For example: var template = "<div>Foo: {bar}</div><div>Blah: {vtha}</div>"; template.interpolate({bar:"bar",blah:"vtha"}); I have cut this down a fair bit - some of my dynamic elements have quite a lot of HTML and a lot going on. I am using jQuery and I am building on Rails, so if there is something smart in either framework, that would be great. For reference, the String interpolation function used above is: String.prototype.interpolate = function (o) { return this.replace(/{([^{}]*)}/g, function (a, b) { var r = o[b]; return typeof r === 'string' || typeof r === 'number' ? r : a; } ); };

  • Find out what variable is throwing a NullPointerException programatically

    - by Hectoret
    I know I can find out if a variable is null in Java using these techniques: if (var==null) - too much work try { ... } catch (NullPointerException e) { ...} - it tells me what line is throwing the exception using the debugger - by hand, too slow Consider this line of code: if (this.superSL.items.get(name).getSource().compareTo(VIsualShoppingList.Source_EXTRA)==0) { I would like to know if there's a generic way to find out programatically what variable (not just the line) is throwing the NullPointerException in a certain area of code. In the example, knowing that

  • How can I expose a service bus by a wcf service to be consumed by a silverlight client

    - by illdev
    In a Silverlight application, instead of consuming and writing (wcf) wrappers around messages that finally get sent to the bus, I want to send use my message bus as directly as possible. My idea was to expose the service bus directly as a wcf service, or, in other terms, I want to bidirectionally pub/sub over the wire. Has this been done already? Is bi-directionality doable at all? After all, we are (are we restricted to that?) in the http domain? Lots of questions. Some head start would be greatly appreciated! I am in .NET land, with using Rhino Service Bus, but the pattern should apply to different platforms.

  • Quick, beginner MASM register question - DX:AX

    - by Francisco P.
    Hello, I am currently studying for an exam I'll have on x86 assembly. I didn't have much luck googling for ":", too common of a punctuation mark :/ IDIV - Signed Integer Division Usage: IDIV src Modifies flags: (AF,CF,OF,PF,SF,ZF undefined) Signed binary division of accumulator by source. If source is a byte value, AX is divided by "src" and the quotient is stored in AL and the remainder in AH. If source is a word value, DX:AX is divided by "src", and the quotient is stored in AL and the remainder in DX. Taken from "Intel Opcodes and Mnemonics" What does DX:AX mean? Thanks a lot for your time :)

  • Google Maps & jQuery InfoWindow Replacement

    - by Denis Hoctor
    Hi all, So I'm rewriting my first google maps app and I'm looking at how I create info windows on click of a marker and it seems very inefficent to be adding a listener for each. Previously I've used GInfoWindow and EBubble (http://econym.org.uk/gmap/ebubble.htm). I was thinking that I could use jQuery to show a div with dynamic data if I had a hook for each marker to show the window and relevant marker info (pulled from JSON). I can see each marker has a unique id (e.g. mtgt_unnamed_2822) but I'm not sure how to predicte this. Has anyone tried this before or know how to go about it? Thanks Denis

  • L'Internet en 3D arrivera d'ici 5 ans d'après Intel, est-ce le futur du web ?

    L'Internet en 3D arrivera d'ici 5 ans d'après Intel, est-ce le futur du web ? Sean Koehl travaille chez Intel en tant que "techno évangéliste". Il s'est réccemment exprimé au sujet du futur d'Internet, et il estime que le réseau "sera complètement différent d'ici 5 à 10 ans". Selon lui, notre manière d'interagir entre nous, et avec des appareils électroniques, va changer. Radicalement. Ainsi, il prédit l'émergence d'une technologie tri-dimensionnelle très réaliste dans 5 ans. Comme de plus en plus de gens autour du monde s'équipent avec des ordinateurs ou des smartphones et ont un accès à l'Internet. Sean explique qu'on commence seulement à exploiter toute cette puissance informatiq...

  • jQuery Cluetip not activated until after hover or click event

    - by kenny99
    I'm not sure what is causing this, but I am using cluetip and binding it to a live event (either click or mouseenter), but in each situation the cluetip isn't firing until after one click or hover event. I am using the live event for ajax loaded content, but I'm also having this issue with non-Ajax loaded content. I'm not sure why this is happening - can anyone see where I might be going wrong? Many thanks. $("a.jTip").live("click", function(){ $('a.jTip').cluetip({ attribute: 'href', cluetipClass: 'jtip', arrows: true, activation: 'click', ajaxCache: false, dropShadow: true, sticky: true, mouseOutClose: false, closePosition: 'title' }) return false; });

  • jquery - get url path?

    I know I can use window.location.pathname to return a url, but how do I parse the url? I have a url like this: http://localhost/messages/mine/9889 and I'm trying to check to see if "mine" exists in that url? So, if "mine" is the second piece in that url, I want to write an if statement based on that... if(second argument == 'mine') { do something }

  • Difference between implementing an interface and applying an attribute in C#

    - by RemotecUk
    This might be a stupid question but Ill ask anyway, I was reading "OOP Demystified: A Self-Teaching Guide by Jim Keogh and Mario Giannini" chapter 11 which covers interfaces. The examples in this book are C++. I noticed that C++ uses ISerializable to make a class serializable which you would implement where as in C# you just attribute the class with the [Serializable] attribute. What is the key difference here? Is it that with an interface you must provide the implementation where as if you attribute something the compiler will work out the implementation for you? I guess that with the [Serializable] attribute the .Net framework uses reflection to make the serialized object from the actual object. That said is it possible in that case to have an [Disposable] attribute or using my theory above the framework wont know how to actually dispose of an object hence you have to do it yourself? Would be grateful for a clarification. Thanks.

  • How to get the time on the point that you click on the clock?

    - by Jeff
    For instance, when you click the clock on the screen, there will pop up a notification/dialog which displays the exact time point. Anyone can tell me how to achieve this function? Thanks in advance! Maybe I should explain the "exact time point" . For example, there is a big analog clock on the screen. When you click around the dial, it will pop up a dialog box to display the exact time.

  • How to get only the first row from a java.sql.ResultSet?

    - by llm
    I have a ResultSet object containing all the rows returned from an sql query. I want to be able to (in the java code, NOT force it in the SQL) to be able to take a ResultSet and transform it so that it only contains 1 (the first) row. What would be the way to acheive this? Also, is there another appropriate class (somewhere in java.sql or elsewhere) for storing just a single row rather than trimming my ResultSet? Thanks!

  • Sequential numbering from recursive function? e.g. 2, 2.1, 2.1.1, 2.2, 2.2.1

    - by Pete
    I have a recursive function reading a "table of contents" of documents from a database. I would like to print numbering with the document that reflects where the item is in the tree, e.g. First item, 1.1 Child of first item, 1.1.1 Child of child of first item, 1.2 Child of first item, Second item, 2.1 Child of second item, etc. Rather stumped about this at the moment - help please?
