  • jquery plugin with multiple functions

    - by tcurdt
    According to the developer documentation jquery plugins are supposed to have only one namespace for all functions they make available. Which is straight forward as long as you only expose a single function per context (static/element). (function($){ var state_a = 0, $.myplugin = function(in_options) { // static return this; } $.fn.myplugin = function(in_options) { // element return this; } })(jQuery); This makes calls like this possible: $("elem").myplugin(options); jQuery.myplugin(options); What's the best approach if you have more than one function and need to share state? I would like to call into my plugin like this: $("elem").myplugin.start(options); $("elem").myplugin.stop(); jQuery.myplugin.start(options); jQuery.myplugin.stop();

  • How do you use kate? Tips/Tricks/Workflow

    - by Roman A. Taycher
    We all seen a bunch of these? Mostly for IDE's but also for vim and emacs. Kate is (only) a text editor (an awesome one) but it has a ton of options plus a number of plugins, so its hard to know all of it well. How do use the Kate text editor? Please share your workflow and help me and others learn some of the cool tricks you use. I'll start I use the built in terminal a lot opening files quickly, and using it as an enhanced haskell repl with ghci (since ghci doesn't allow you all to just put in all kinds of haskell code). Also use split views to quickly compare files (especially different versions of the same file). Also the auto-complete maybe simple(more use for saving typing time then remembering functions) but it works really well for that. Also if You highlight something and hit a start [/{/( it puts it in between brackets rather then replacing it with a bracket(why the hell do a lot of IDEs not have this feature).

  • Joomla Template Design

    - by John
    Hi, Can I create any design I want and then use it in a Joomla template or is there certain rules you have to stick to? I ask this as most of the Joomla templates I see pretty much have the same layout e.g. top bar content box, right hand menu and bottom bar. Thanks

  • Running a Windows Forms app. from a service.

    - by RemotecUk
    Hi, I have a strange application in that for development and testing I need a windows forms application so that I can monitor what it is doing. For production, the application will be started from a service and no visible UI is needed. I dont really want to re-write the app. once it is completed into a console app so I would like to leave it as it but start it from the service. My question is will this application work fine from a service? At the moment it has UI elements and I have been able to successfully start the application from a service using the Process class (System.Diagnostics). Could anything go wrong with this approach?

  • Oracle Hash Cluster Overflow Blocks

    - by Andrew
    When inserting a large number of rows into a single table hash cluster in Oracle, it will fill up the block with any values that hash to that hash-value and then start using overflow blocks. These overflow blocks are listed as chained off the main block, but I can not find detailed information on the way in which they are allocated or chained. When an overflow block is allocated for a hash value, is that block exclusively allocated to that hash value, or are the overflow blocks used as a pool and different hash values can then start using the same overflow block. How is the free space of the chain monitored - in that, as data is continued to be inserted, does it have to traverse the entire chain to find out if it has some free space in the current overflow chain, and then if it finds none, it then chooses to allocate a new block?

  • Grouping Months of a particular Time span together using DateTime.

    - by Calibre2010
    public static string TimeLine2(this HtmlHelper helper, string myString2) { StringBuilder myString3 = new StringBuilder(); DateTime start = new DateTime(2010, 1, 1); DateTime end = new DateTime(2011, 12, 12); myString3.Append("<table>"); myString3.Append("<tr>"); for (DateTime date = start; date <= end; date = date.AddDays(1)) { DayOfWeek dw = date.DayOfWeek; var g = date.Month; var sun = " "; switch (dw) { case DayOfWeek.Sunday: sun = "S"; break; case DayOfWeek.Monday: sun = "M"; break; case DayOfWeek.Tuesday: sun = "T"; break; case DayOfWeek.Wednesday: sun = "W"; break; case DayOfWeek.Thursday: sun = "T"; break; case DayOfWeek.Friday: sun = "F"; break; case DayOfWeek.Saturday: sun = "S"; break; } myString3.Append("<td>" + sun + " " + g + "</td>"); } myString3.Append("</tr>"); myString3.Append("<tr>"); for (DateTime date = start; date <= end; date = date.AddDays(1)) { var f = date.Day; myString3.Append("<td>" + f + "</td>"); } myString3.Append("</tr>"); myString3.Append("</table>"); return myString3.ToString(); } Basically, what I have here is a few loops showing all the days of the week and also all the days in a month. This is all placed inside of a table, so you get MTWTFSSMT W T F S S M M TWTFSSM 12345678910 11 12 13 14 + + to 31 1234567 I'm trying to code a way in which I can split all of these days of the week and days in months so that my code returns each month with all its days in the month and all its days of the week, not just all my months between my timeSpan but splits them so MAY MTWTFSSMTWTFSSMTWTFSSMTWTFSSMTWTF 12345678 JUNE MTWTFSSMTWTFSSMTWTFSSMTWTFSSMTWTF 123456789

  • Best way to handle SQL Server fulltext index updates

    - by tlianza
    Hi all, I have a fulltext index which doesn't need to be immediately up-to-date, I'd like to spare myself the I/O (when I do bulk updates, I see a ton of I/O related to the index) and do the index updates during low usage times (nightly, perhaps even weekly). It seems there are two ways to go about this: Turn off change tracking (SET CHANGE_TRACKING OFF) and add a timestamp field to the indexed table, so that you can run alter fulltext index on <table> start INCREMENTAL population, or Enable change tracking, but set it to MANUAL, so that you can run alter fulltext index on <table> start UPDATE population when you need it updated. Is there a preferred method? I couldn't tell from this overview if there was a performance benefit one way or the other. Tom

  • Scala actors: receive vs react

    - by jqno
    Let me first say that I have quite a lot of Java experience, but have only recently become interested in functional languages. Recently I've started looking at Scala, which seems like a very nice language. However, I've been reading about Scala's Actor framework in Programming in Scala, and there's one thing I don't understand. In chapter 30.4 it says that using react instead of receive makes it possible to re-use threads, which is good for performance, since threads are expensive in the JVM. Does this mean that, as long as I remember to call react instead of receive, I can start as many Actors as I like? Before discovering Scala, I've been playing with Erlang, and the author of Programming Erlang boasts about spawning over 200,000 processes without breaking a sweat. I'd hate to do that with Java threads. What kind of limits am I looking at in Scala as compared to Erlang (and Java)? Also, how does this thread re-use work in Scala? Let's assume, for simplicity, that I have only one thread. Will all the actors that I start run sequentially in this thread, or will some sort of task-switching take place? For example, if I start two actors that ping-pong messages to each other, will I risk deadlock if they're started in the same thread? According to Programming in Scala, writing actors to use react is more difficult than with receive. This sounds plausible, since react doesn't return. However, the book goes on to show how you can put a react inside a loop using Actor.loop. As a result, you get loop { react { ... } } which, to me, seems pretty similar to while (true) { receive { ... } } which is used earlier in the book. Still, the book says that "in practice, programs will need at least a few receive's". So what am I missing here? What can receive do that react cannot, besides return? And why do I care? Finally, coming to the core of what I don't understand: the book keeps mentioning how using react makes it possible to discard the call stack to re-use the thread. How does that work? Why is it necessary to discard the call stack? And why can the call stack be discarded when a function terminates by throwing an exception (react), but not when it terminates by returning (receive)? I have the impression that Programming in Scala has been glossing over some of the key issues here, which is a shame, because otherwise it's a truly excellent book.

  • SDK for writing DVD's

    - by Matt Warren
    I need to add DVD writing functionality to an application I'm working on. However it needs to be able to write out files that are being grabbed "live" from a camera, over a long period of time. I can't wait until all the files are captured before I start writing them to the DVD, I need to write them out in chunks as I go along. I've looked at IMAPI v2, but the main problems seems to be that you need to point it to all the files you plan to write out to disk before you start the burning process. I know it has to concept of "sessions", which means you can write to the DVD in several parts, before you finally "close" it. But I was wondering if there were any other DVD writing SDK's that allow you to be constantly writing files to a DVD and in particular files that are only in memory. It would be more efficient if I didn't have to write the captured images out to hard before they are burned to DVD. The solution needs to work under .NET on Windows XP and vista

  • Cancel outlook meeting requests via MailMessage in C#

    - by BTmuney
    I'm creating an application using the ASP.NET MVC 1 framework in C#, where I have users that register for events. Upon registering, I create an outlook meeting request public string BuildMeetingRequest(DateTime start, DateTime end, string attendees, string organizer, string subject, string description, string UID, string location) { System.Text.StringBuilder sw = new System.Text.StringBuilder(); sw.AppendLine("BEGIN:VCALENDAR"); sw.AppendLine("VERSION:2.0"); sw.AppendLine("METHOD:REQUEST"); sw.AppendLine("BEGIN:VEVENT"); sw.AppendLine(attendees); sw.AppendLine("CLASS:PUBLIC"); sw.AppendLine(string.Format("CREATED:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow)); sw.AppendLine("DESCRIPTION:" + description); sw.AppendLine(string.Format("DTEND:{0:yyyyMMddTHHmmssZ}", end)); sw.AppendLine(string.Format("DTSTAMP:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow)); sw.AppendLine(string.Format("DTSTART:{0:yyyyMMddTHHmmssZ}", start)); sw.AppendLine("ORGANIZER;CN=\"NAME\":mailto:" + organizer); sw.AppendLine("SEQUENCE:0"); sw.AppendLine("UID:" + UID); sw.AppendLine("LOCATION:" + location); sw.AppendLine("SUMMARY;LANGUAGE=en-us:" + subject); sw.AppendLine("BEGIN:VALARM"); sw.AppendLine("TRIGGER:-PT720M"); sw.AppendLine("ACTION:DISPLAY"); sw.AppendLine("DESCRIPTION:Reminder"); sw.AppendLine("END:VALARM"); sw.AppendLine("END:VEVENT"); sw.AppendLine("END:VCALENDAR"); return sw.ToString(); } And once built, I use MailMessage, with an alternate view to send out the meeting request: meetingInfo = BuildMeetingRequest(start, end, attendees, organizer, subject, description, UID, location); System.Net.Mime.ContentType mimeType = new System.Net.Mime.ContentType("text/calendar; method=REQUEST"); AlternateView ICSview = AlternateView.CreateAlternateViewFromString(meetingInfo,mimeType); MailMessage message = new MailMessage(); message.To.Add(to); message.From = new MailAddress(from); message.AlternateViews.Add(ICSview); SmtpClient client = new SmtpClient(); client.Send(message); When users get the email in outlook, it shows up as a meeting request, as opposed to a normal email. This works well for sending out updates to the meeting request as well. The only problem that I am having is that I do not know the proper format for sending out a cancellation. I've attempted to examine some meeting request cancellations in text editors and can't seem to pinpoint the difference in the format between cancelling/creating. Any help on this is greatly appreciated.

  • Webdav -- GET on a directory

    - by Joe Cannatti
    I am beginning to build a tool that uses WebDAV. I am having trouble wrapping my head around something here. I think I am missing something conceptual. I can use PUT's to add files to the server. I can use GET's to read files from the server, but when I try to use GET on a directory I get a 403:Forbidden. I am using basic authentication. My code in MacRuby is as follows Net::HTTP.start('localhost') do |http| res = Net::HTTP::Get.new('http://localhost/webdav/') res.basic_auth 'jcannatti', 'webdav' http.request res end this returns <Net::HTTPForbidden 403 Forbidden readbody=true> however this Net::HTTP.start('localhost') do |http| res = Net::HTTP::Put.new('http://localhost/webdav/gorilla.txt') res.body = "testetsetest" res.basic_auth 'jcannatti', 'webdav' http.request res end returns <Net::HTTPCreated 201 Created readbody=true> What should happen when calling a GET on a WebDAV directory when everything is working correctly? thanks

  • How to optimize Dijkstra algorithm for a single shortest path between 2 nodes?

    - by Nazgulled
    Hi, I was trying to understand this implementation in C of the Dijkstra algorithm and at the same time modify it so that only the shortest path between 2 specific nodes (source and destination) is found. However, I don't know exactly what do to. The way I see it, there's nothing much to do, I can't seem to change d[] or prev[] cause those arrays aggregate some important data for the shortest path calculation. The only thing I can think of is stopping the algorithm when the path is found, that is, break the cycle when mini = destination when it's being marked as visited. Is there anything else I could do to make it better or is that enough? P.S: I just noticed that the for loops start at 1 until <=, why can't it start at 0 and go until <?

  • Getting clusters of rows close together in time

    - by Mike
    I have a table basically like so ID | ItemID | Start | End | --------------------------------------------------------------- 1 234 10/20/09 8:34:22 10/20/09 8:35:10 2 274 10/20/09 8:35:30 10/20/09 8:36:27 3 272 10/21/09 12:15:00 10/21/09 12:17:00 4 112 10/21/09 12:20:14 10/21/09 12:21:21 5 15 10/21/09 12:22:39 10/21/09 12:24:15 There are two "clusters" of entries here, 1-2 and 3-5 separated by a gap in time, specifically 30 minutes is what I'm interested in. What I would like is the first and last rows of the cluster of entries. This is fairly easy to achieve by retrieving all the rows and looping through them in order of start time, but I'd like to have it in SQL if possible. I'm using SQL Server 2008, thanks.

  • How is the Tomcat temp directory location defined?

    - by sdoca
    I am running Tomcat bundled with Liferay5.2.3 and use Eclipse 3.5 (Galileo) as my IDE. I set up my Tomcat server in Eclipse as per this blog entry: http://www.jroller.com/holy/entry/developing_portlets_for_liferay_in. If I start Tomcat via the Eclipse server config, Liferay/Tomcat uses my C:\Documents and Settings\user\Local Settings\Temp\ directory. However, if I start Tomcat directly using the startup.bat script, Liferay/Tomcat uses the Tomcat temp directory. I can't figure out if Eclipse, Liferay or Tomcat is deciding which temp directory to use or how to change it. I would prefer to use the Tomcat temp directory. I have this issue with both the Lifera/Tomcat bundles 5.5 and 6.0 (liferay-portal-tomcat-6.0-5.2.3.zip and liferay-portal-tomcat-5.5-5.2.3.zip). Anybody have any clues?

  • What are some of the practical cons to using ASMX webservices?

    - by Earlz
    Hello, at my workplace we are about to start a big project. My boss (a programmer, this is a startup) wishes to use ASMX webservices for this purpose. I do not want to start off a new program using deprecated technology and would like to show him this. I dislike WCF at this moment because it has such an extreme learning curve, but I'd rather learn it than use an unsupported technology. The problem I'm having is that I can not find any practical list of cons and downfalls when compared to WCF so that I can convince my boss to not use them. And saying "it's not as powerful" is not an adequate explanation. What exactly can it not do that we may need it to do for a webservice that is not meant to be shared externally? (as in, we don't support third-parties using our webservices unless they are using one of our clients. )
