  • EC2 persistence of machine

    - by Seagull
    I want to 'persist' my Amazon EC2 images. My scenario: I have a range of Windows and Linux machines Some machines are EBS backed, whereas others are S3 backed. I need to be able to persist a machine (put it to sleep), preferably keeping all settings active I had them when the machine was running. I need to be able to quickly wake up a machine from sleep [Ideally with an SLA of less than 2 min to turn-on, if such an SLA is available with Amazon]. Here's the stuff that confuses me: AWS allows me to put EBS backed machines to sleep, but not S3 backed. I believe I can put S3 machines into some sort of persistence mode. But this involves shutting down the machine, writing it to S3 storage and then recovering from there (not a real sleep mode, but at least I don't continue to get billed for CPU). S3 backing seems to take a long time to either writing a machine to disk, or to recover (turn on a machine). I can't tell immediately which machines are EBS backed and which are S3 backed? It seems like I can instantiate either type, but it's not immediately clear how Amazon decided whether a given machine should be EBS or S3 backed. Advice?

  • How to calculate this string-dissimilarity function efficiently?

    - by ybungalobill
    Hello, I was looking for a string metric that have the property that moving around large blocks in a string won't affect the distance so much. So "helloworld" is close to "worldhello". Obviously Levenshtein distance and Longest common subsequence don't fulfill this requirement. Using Jaccard distance on the set of n-grams gives good results but has other drawbacks (it's a pseudometric and higher n results in higher penalty for changing single character). [original research] As I thought about it, what I'm looking for is a function f(A,B) such that f(A,B)+1 equals the minimum number of blocks that one have to divide A into (A1 ... An), apply a permutation on the blocks and get B: f("hello", "hello") = 0 f("helloworld", "worldhello") = 1 // hello world -> world hello f("abba", "baba") = 2 // ab b a -> b ab a f("computer", "copmuter") = 3 // co m p uter -> co p m uter This can be extended for A and B that aren't necessarily permutations of each other: any additional character that can't be matched is considered as one additional block. f("computer", "combuter") = 3 // com uter -> com uter, unmatched: p and b. Observing that instead of counting blocks we can count the number of pairs of indices that are taken apart by a permutation, we can write f(A,B) formally as: f(A,B) = min { C(P) | P:|A|?|B|, P is bijective, ?i?dom(P) A[P(i)]=B[P(i)] } C(P) = |A| + |B| - |dom(P)| - |{ i | i,i+1?dom(P) and P(i)+1=P(i+1) }| - 1 The problem is... guess what... ... that I'm not able to calculate this in polynomial time. Can someone suggest a way to do this efficiently? Or perhaps point me to already known metric that exhibits similar properties?

  • jquery noob problem with variables (scope?)

    - by aharon
    I'm trying to retrieve data from a php file named return that just contains <?php echo 'here is a string'; ?> I'm doing this through an html file containing <!DOCTYPE html> <html> <head> <script src="http://code.jquery.com/jquery-latest.min.js"></script> <script> var x; $.get("return.php", function(data){ x = data; }) function showAlert() {alert(x);} $(document).ready(function(){ alert(x); }); </script> </head> <body> <input type = "button" value = "Click here" onClick="showAlert();"> </body> </html> When the button is clicked it retrieves and displays the code fine, but on the $(document).ready thing, it displays "undefined" instead of the data in return.php. Any solutions? Thanks.

  • jQuery update not replacing js files in Drupal 6.16.

    - by vr3690
    Hi, I am using jquery update in drupal 6.16 along with a lot of other modules. I am trying to use jquery ui 1.7.2 to render tabs. But unfortunately they don't work properly since jquery update is not replacing the jquery file (jquery 1.3.2). I checked the version using $.fn.jquery (in firebug) and got 1.2.6 (not 1.3.2 as required) as the result - and as expected the aggregated js file was using the 1.2.6 version of jquery (see source). earlier I had just replaced the core script files in /misc with the js files in sites/default/modules/jquery_update/replace folder (like you'd do in 5.x) and got the necessary result (i also renamed jquery.min.js to jquery.js ). now suddenly that stopped working after i upgraded to 6.x-2.0-alpha1 and also installed the mollom module. disabling/uninstalling mollom or down-grading jQuery update does not seem to help. the problem only occurs on the front page though. other content pages have jQuery 1.3.2 the problem can be seen here. So, basically, for some reason, jquery update is not replacing the jquery files (as it is supposed to) on the front page. and i cannot figure out why that happens. any ideas?

  • Persistence of texture parameters

    - by fen
    I use glBindTexture() to bind a previously created texture. After the glBindTexture() call I use glTexParameteri() to set MIN and MAG filter. No problem so far. Are those parameters I set using glTexParameteri() bound to the texture itself or are they lost if I bind another texture. Do i have to set them again? glGenTexture(1, &tex1); glGenTexture(1, &tex2); /* bind tex1 and set params */ glBindtexture(GL_TEXTURE_RECTANGLE_ARB, tex1); glTexImage2D(GL_TEXTURE_RECTANGLE_ARB, ...); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MAG_FILTER, GL_LINEAR); /* do something */ /* bind tex2 and set params */ glBindtexture(GL_TEXTURE_RECTANGLE_ARB, tex2); glTexImage2D(GL_TEXTURE_RECTANGLE_ARB, ...); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MAG_FILTER, GL_LINEAR); /* do something */ /* bind tex1 again */ glBindtexture(GL_TEXTURE_RECTANGLE_ARB, tex1); /* do i have to set the parameters from above again or are they stored with tex1? */

  • How can I convert seconds to minutes in jQuery while updating an element with the current time?

    - by pghtech
    So I see a number of ways to display allot of seconds in a (static) hr/min/sec. However, I am trying to produce a visual count down timer: $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); My counter is reduced inside a SetInterval that triggers ever 1 second: //....... var counter = redirectTimer; jQuery('#WarningDialogMsg').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); //........ SetInternval( function() { counter -= 1; secCounter = Math.floor(counter % 60); minCounter = Math.floor(counter / 60); //....... $('#someelement').html(minCounter + ' minutes ' + ((secCounter == 0) ? '' : (secCounter + ' seconds'))); }, 1000) It is a two minute counter but I don't want to display 120 seconds. I want to display 1 : 59 (and counting down). I have managed to get it to work using the above, but my main question is: is there a more elegant way to accomplish the above? (note: I am redirecting once "counter == 0").

  • jquery-ui autocomplete with ASP MVC suggestions not displaying

    - by adamnickerson
    I have been trying to get a simple example of the jquery-ui autocomplete to work. I have a controller setup to handle the query, and it returns the json that looks to be in order, but I am getting no suggestions showing up. Here are the js libraries I am including: <script type="text/javascript" language="javascript" src="/Scripts/jquery-1.4.1.js"></script> <script type="text/javascript" language="javascript" src="/Scripts/jquery-ui-1.8.1.custom.min.js"></script> <link href="/Content/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> and here is the javascript and the form tags: <script type="text/javascript"> $(function () { $("#organization").autocomplete({ source: function (request, response) { $.ajax({ url: '/Organization/OrganizationLookup', dataType: "json", data: { limit: 12, q: request.term } }) }, minLength: 2 }); }); </script> <div class="ui-widget"> <label for="organization">Organization: </label> <input id="organization" /> </div> I get back a json response that looks reasonable from my controller: [{"id":"Sector A","value":"Sector A"},{"id":"Sector B","value":"Sector B"},{"id":"Sector C","value":"Sector C"}] id and value seem to be the default naming that autocomplete is looking for. But I get no joy at all. Any thoughts?

  • Assign click event to addon icon on navigation bar

    - by Charsee
    We have created a chrome extension for our app. Where we call a METHOD from a "js file" on CLICK event of the "extension icon" placed on the navigation bar. For this we use message passing between the app.js (file containing the METHOD to be called on icon click) and background.html (using a js file included in this html). The script used to pass message is:(from background.html) chrome.browserAction.onClicked.addListener(function (tab) { chrome.tabs.sendMessage(tab.id, "showPopup"); }); and to listen the message :(in app.js) chrome.extension.onMessage.addListener(function(request) { if (request === "showPopup") { showPopup(); } }); The click event works as expected. But now we want to do same thing in mozilla extension. and we can't pass message to app.js on the click of the icon,so that it can execute the containing methods. We have also added the app.js using pageMod, something like this exports.main = function(options, callbacks) { pageMod.PageMod({ include: ["*"], contentScriptWhen: 'start', contentScriptFile: [data.url('jquery-1.7.1.min.js'),data.url('app.js')] }); createAndAddNavBarButton(); }; function createAndAddNavBarButton() { var navBar = document.getElementById('nav-bar');//assume document has been defined if (!navBar){return;}; var nbBtn = document.createElement('navbaricon'); nbBtn.setAttribute('id', 'navButton'); nbBtn.setAttribute('image', data.url('icon_16.png')); nbBtn.onclick = function(){ showPopup(); return true; } navBar.appendChild(btn); } But the click event does nothing and showPopup() is undefined. When a new page loads event associated with it in the app.js executes without any error but the click event doesn't work. Is there a method from where we can assign click event directly to this icon, as we have done in the case of chrome extension.

  • SQL query for selecting the firsts in a series by cloumn

    - by SP
    I'm having some trouble coming up with a query for what I am trying to do. I've got a table we'll call 'Movements' with the following columns: RecID(Key), Element(f-key), Time(datetime), Room(int) The table is holding a history of Movements for the Elements. One record contains the element the record is for, the time of the recorded location, and the room it was in at that time. What I would like are all records that indicate that an Element entered a room. That would mean the first (by time) entry for any element in a series of movements for that element in the same room. The input is a room number and a time. IE, I would like all of the records indicating that any Element entered room X after time Y. The closest I came was this Select Element, min(Time) from Movements where Time > Y and Room = x group by Element This will only give me one room entry record per Element though (If the Element has entered the room X twice since time Y I'll only get the first one back) Any ideas? Let me know if I have not explained this clearly. I'm using MS SQLServer 2005.

  • how to get access to private members of nested class?

    - by macias
    Background: I have enclosed (parent) class E with nested class N with several instances of N in E. In the enclosed (parent) class I am doing some calculations and I am setting the values for each instance of nested class. Something like this: n1.field1 = ...; n1.field2 = ...; n1.field3 = ...; n2.field1 = ...; ... It is one big eval method (in parent class). My intention is -- since all calculations are in parent class (they cannot be done per nested instance because it would make code more complicated) -- make the setters only available to parent class and getters public. And now there is a problem: when I make the setters private, parent class cannot acces them when I make them public, everybody can change the values and C# does not have friend concept I cannot pass values in constructor because lazy evaluation mechanism is used (so the instances have to be created when referencing them -- I create all objects and the calculation is triggered on demand) I am stuck -- how to do this (limit access up to parent class, no more, no less)? I suspect I'll get answer-question first -- "but why you don't split the evaluation per each field" -- so I answer this by example: how do you calculate min and max value of a collection? In a fast way? The answer is -- in one pass. This is why I have one eval function which does calculations and sets all fields at once.

  • Rotate MapView in Android

    - by Matthew B.
    I am writing an Android app where one of the features is that the map will rotate according to the compass (i.e. if the phone is pointing east, the map will be oriented so that the east side of the map is on top). Previous answers that I have found suggested over writing the onDraw() method in mapView, however, the api changed the method to final so it cannot be overwritten. As a result I have tried to overwrite the dispatchDraw() method like so: Note: -compass is a boolean that if true, rotate the view -bearing is a float variable that has the degrees that the view should rotate protected void dispatchDraw(Canvas canvas) { canvas.save(); if (compass) { final float w = this.getWidth(); final float h = this.getHeight(); final float scaleFactor = (float)(Math.sqrt(h * h + w * w) / Math.min(w, h)); final float centerX = w / 2.0f; final float centerY = h / 2.0f; canvas.rotate(bearing, centerX, centerY); canvas.scale(scaleFactor, scaleFactor, centerX, centerY); } super.dispatchDraw(canvas); canvas.restore(); }

  • Python's asyncore to periodically send data using a variable timeout. Is there a better way?

    - by Nick Sonneveld
    I wanted to write a server that a client could connect to and receive periodic updates without having to poll. The problem I have experienced with asyncore is that if you do not return true when dispatcher.writable() is called, you have to wait until after the asyncore.loop has timed out (default is 30s). The two ways I have tried to work around this is 1) reduce timeout to a low value or 2) query connections for when they will next update and generate an adequate timeout value. However if you refer to 'Select Law' in 'man 2 select_tut', it states, "You should always try to use select() without a timeout." Is there a better way to do this? Twisted maybe? I wanted to try and avoid extra threads. I'll include the variable timeout example here: #!/usr/bin/python import time import socket import asyncore # in seconds UPDATE_PERIOD = 4.0 class Channel(asyncore.dispatcher): def __init__(self, sock, sck_map): asyncore.dispatcher.__init__(self, sock=sock, map=sck_map) self.last_update = 0.0 # should update immediately self.send_buf = '' self.recv_buf = '' def writable(self): return len(self.send_buf) > 0 def handle_write(self): nbytes = self.send(self.send_buf) self.send_buf = self.send_buf[nbytes:] def handle_read(self): print 'read' print 'recv:', self.recv(4096) def handle_close(self): print 'close' self.close() # added for variable timeout def update(self): if time.time() >= self.next_update(): self.send_buf += 'hello %f\n'%(time.time()) self.last_update = time.time() def next_update(self): return self.last_update + UPDATE_PERIOD class Server(asyncore.dispatcher): def __init__(self, port, sck_map): asyncore.dispatcher.__init__(self, map=sck_map) self.port = port self.sck_map = sck_map self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.bind( ("", port)) self.listen(16) print "listening on port", self.port def handle_accept(self): (conn, addr) = self.accept() Channel(sock=conn, sck_map=self.sck_map) # added for variable timeout def update(self): pass def next_update(self): return None sck_map = {} server = Server(9090, sck_map) while True: next_update = time.time() + 30.0 for c in sck_map.values(): c.update() # <-- fill write buffers n = c.next_update() #print 'n:',n if n is not None: next_update = min(next_update, n) _timeout = max(0.1, next_update - time.time()) asyncore.loop(timeout=_timeout, count=1, map=sck_map)

My GC starts work normally, I see a lot of small GCs and all that time CPU shows good load, like all 4 cores loaded to 40-50%, CPU graph is stable. Then , after 1 min of good work, CPU starts drop to 0% on 2 cores from 4, it's graph becomes unstable, goes up and down("teeth"). I see, that my threads work slower(I have monitoring), I see that GC starts produce a lot of FULL GC during that time and next 4-5 minutes this situation remains as is, then for short period of time, like 1 minute, it gets back to normal situation, but shortly after that all bad thing repeats. Question: Why I have so frequent full GC??? How to prevent that? I played with SurvivorRatio - does not help.

  • How can I optimize retrieving lowest edit distance from a large table in SQL?

    - by Matt
    Hey, I'm having troubles optimizing this Levenshtein Distance calculation I'm doing. I need to do the following: Get the record with the minimum distance for the source string as well as a trimmed version of the source string Pick the record with the minimum distance If the min distances are equal (original vs trimmed), choose the trimmed one with the lowest distance If there are still multiple records that fall under the above two categories, pick the one with the highest frequency Here's my working version: DECLARE @Results TABLE ( ID int, [Name] nvarchar(200), Distance int, Frequency int, Trimmed bit ) INSERT INTO @Results SELECT ID, [Name], (dbo.Levenshtein(@Source, [Name])) As Distance, Frequency, 'False' As Trimmed FROM MyTable INSERT INTO @Results SELECT ID, [Name], (dbo.Levenshtein(@SourceTrimmed, [Name])) As Distance, Frequency, 'True' As Trimmed FROM MyTable SET @ResultID = (SELECT TOP 1 ID FROM @Results ORDER BY Distance, Trimmed, Frequency) SET @Result = (SELECT TOP 1 [Name] FROM @Results ORDER BY Distance, Trimmed, Frequency) SET @ResultDist = (SELECT TOP 1 Distance FROM @Results ORDER BY Distance, Trimmed, Frequency) SET @ResultTrimmed = (SELECT TOP 1 Trimmed FROM @Results ORDER BY Distance, Trimmed, Frequency) I believe what I need to do here is to.. Not dumb the results to a temporary table Do only 1 select from `MyTable` Setting the results right in the select from the initial select statement. (Since select will set variables and you can set multiple variables in one select statement) I know there has to be a good implementation to this but I can't figure it out... this is as far as I got: SELECT top 1 @ResultID = ID, @Result = [Name], (dbo.Levenshtein(@Source, [Name])) As distOrig, (dbo.Levenshtein(@SourceTrimmed, [Name])) As distTrimmed, Frequency FROM MyTable WHERE /* ... yeah I'm lost */ ORDER BY distOrig, distTrimmed, Frequency Any ideas?

  • ASP.NET MVC3 - Bug using Javascript

    - by ebb
    Hey there, I'm trying to use Ajax.BeginForm() to POST A Json result from my controller (I'm using MVC3). When the Json result is called it should be sent to a javascript function and extract the object using "var myObject = content.get_response().get_object();", However it just throws a "Microsoft JScript runtime error: Object doesn't support this property or method" when trying to invoke the Ajax POST. My code: Controller: [HttpPost] public ActionResult Index(string message) { return Json(new { Success = true, Message = message }); } View: <!DOCTYPE html> <html> <head> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script type="text/javascript"> function JsonAdd_OnComplete(mycontext) { var myObject = mycontext.get_response().get_object(); alert(mycontext.Message); } </script> </head> <body> <div> @using(Ajax.BeginForm("Index", "Home", new AjaxOptions() { HttpMethod = "POST", OnComplete = "JsonAdd_OnComplete" })) { @Html.TextBox("message") <input type="submit" value="SUBMIT" /> } </div> </body> </html> The strange thing is that the exactly same code works in MVC2 - Is this a bug, or have I forgot something? Thanks in advance.

  • document.write Not working when loading external Javascript source

    - by jadent
    I'm trying to load an external JavaScript file dynamically into an HTML element to preview an ad tag. The script loads and executes but the script contains "document.write" which has an issue executing properly but there are no errors. <html> <head> <script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script> <script type="text/javascript"> $(function() { source = 'http://ib.adnxs.com/ttj?id=555281'; // DOM Insert Approach // ----------------------------------- var script = document.createElement('script'); script.setAttribute('type', 'text/javascript'); script.setAttribute('src', source); document.body.appendChild(script); }); </script> </head> <body> </body> </html> I can get it to work if If i move the the source to the same domain for testing If the script was modified to use document.createElement and appendChild instead of document.write like the code above. I don't have the ability to modify the script since it being generated and hosted by a 3rd party. Does anyone know why the document.write will not work correctly? And is there a way to get around this? Thanks for the help!

  • How can I emulate Vim's * search in GNU Emacs?

    - by rq
    In Vim the * key in normal mode searches for the word under the cursor. In GNU Emacs the closest native equivalent would be: C-s C-w But that isn't quite the same. It opens up the incremental search mini buffer and copies from the cursor in the current buffer to the end of the word. In Vim you'd search for the whole word, even if you are in the middle of the word when you press *. I've cooked up a bit of elisp to do something similar: (defun find-word-under-cursor (arg) (interactive "p") (if (looking-at "\\<") () (re-search-backward "\\<" (point-min))) (isearch-forward)) That trots backwards to the start of the word before firing up isearch. I've bound it to C-+, which is easy to type on my keyboard and similar to *, so when I type C-+ C-w it copies from the start of the word to the search mini-buffer. However, this still isn't perfect. Ideally it would regexp search for "\<" word "\>" to not show partial matches (searching for the word "bar" shouldn't match "foobar", just "bar" on its own). I tried using search-forward-regexp and concat'ing \ but this doesn't wrap in the file, doesn't highlight matches and is generally pretty lame. An isearch-* function seems the best bet, but these don't behave well when scripted. Any ideas? Can anyone offer any improvements to the bit of elisp? Or is there some other way that I've overlooked?

  • Strings exported from a module have extra line breaks

    - by Jesse Millikan
    In a DrScheme project, I'm using a MrEd editor-canvas% with text% and inserting a string from a literal in a Scheme file. This results in an extra blank line in the editor for each line of text I'm trying to insert. I've tracked this down to the apparent fact that string literals from outside modules are getting extra line breaks. Here's a full example. The editor is irrelevant at this point, but it displays the result. ; test-literals.ss (module test-literals scheme (provide (all-defined-out)) (define exported-string "From another module with some more line breaks. ")) ; editor-test.ss (module editor-test scheme (require mred "test-literals.ss") (define w (instantiate frame% ("Editor Test" #f) )) (define c (instantiate editor-canvas% (w) (line-count 12) (min-width 400))) (define editor (instantiate text% ())) (send c set-editor editor) (send w show #t) (send editor erase) (send editor insert "Some text with some line breaks. ") (send editor insert exported-string)) And the result in the editor is Some text with some line breaks. From another module with some more line breaks.

  • python tkinter gui

    - by Lewis Townsend
    I'm wanting to make a small python program for yearly temperatures. I can get nearly everything working in the standard console but I'm wanting to implement it into a GUI. The program opens a csv file reads it into lists, works out the average, and min & max temps. Then on closing the application will save a summary to a new text file. I am wanting the default start up screen to show All Years. When a button is clicked it just shows that year's data. Here is a what I want it to look like. Pretty simple layout with just the 5 buttons and the out puts for each. I can make up the buttons for the top fine with: Code: class App: def __init__(self, master): frame = Frame(master) frame.pack() self.hi_there = Button(frame, text="All Years", command=self.All) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2011", command=self.Y1) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2012", command=self.Y2) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2013", command=self.Y3) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="Save & Exit", command=self.Exit) self.hi_there.pack(side=LEFT) I'm not sure as to how to make the other elements, such as the title & table. I was going to post the code of the small program but decided not to. Once I have the structure/framework I think I can populate the fields & I might learn better this way. Using Python 2.7.3

  • Possibility of a custom Contacts field with a set list of values and Contacts lookup performance

    - by areyling
    I'm pretty sure it's not viable to do what I'd like to based on some initial research, but I figured it couldn't hurt to ask the community of experts here in case someone knows a way. I'd like to create a custom field for contacts that the user is able to edit from the main Contacts app; however, the user should only be allowed to select from a list of four specific values. A short list of string values would be ideal, but an int with a min/max range would suffice. I'm interested in knowing if it's possible either way, but also wondering if it make sense to go this route performance wise. More specifically, would it be better to look up a contact (based on a phone number) each time a call or SMS message is received or better to store my own set of data (consisting of name, numbers, and the custom field) and just syncing contact info in a thread every so often? Or syncing contacts the first time the app is run and then registering for changes using ContentObserver? Here is a similar question with an answer that explains how to add a custom field to a contact. Thanks in advance.

  • How can I differentiate a manual scroll (via mousewheel/scrollbar) from a Javascript/jQuery scroll?

    - by David Murdoch
    UPDATE: Here is a jsbin example demonstrating the problem. Basically, I have the following javascript which scrolls the window to an anchor on the page: // get anchors with href's that start with "#" $("a[href^=#]").live("click", function(){ var target = $($(this).attr("href")); // if the target exists: scroll to it... if(target[0]){ // If the page isn't long enough to scroll to the target's position // we want to scroll as much as we can. This part prevents a sudden // stop when window.scrollTop reaches its maximum. var y = Math.min(target.offset().top, $(document).height() - $(window).height()); // also, don't try to scroll to a negative value... y=Math.max(y,0); // OK, you can scroll now... $("html,body").stop().animate({ "scrollTop": y }, 1000); } return false; }); It works perfectly......until I manually try to scroll the window. When the scrollbar or mousewheel is scrolled I need to stop the current scroll animation...but I'm not sure how to do this. This is probably my starting point... $(window).scroll(e){ if(IsManuallyScrolled(e)){ $("html,body").stop(); } } ...but I'm not sure how to code the IsManuallyScrolled function. I've checked out e (the event object) in Google Chrome's console and AFAIK there is not way to differentiate between a manual scroll and jQuery's animate() scroll. How can I differentiate between a manual scroll and one called via jQuery's $.fn.animate function?

  • Match subpatterns in any order

    - by Yaroslav
    I have long regexp with two complicated subpatters inside. How i can match that subpatterns in any order? Simplified example: /(apple)?\s?(banana)?\s?(orange)?\s?(kiwi)?/ and i want to match both of apple banana orange kiwi apple orange banana kiwi It is very simplified example. In my case banana and orange is long complicated subpatterns and i don't want to do something like /(apple)?\s?((banana)?\s?(orange)?|(orange)?\s?(banana)?)\s?(kiwi)?/ Is it possible to group subpatterns like chars in character class? UPD Real data as requested: 14:24 26,37 Mb 108.53 01:19:02 06.07 24.39 19:39 46:00 my strings much longer, but it is significant part. Here you can see two lines what i need to match. First has two values: length (14 min 24 sec) and size 26.37 Mb. Second one has three values but in different order: size 108.53 Mb, length 01 h 19 m 02 s and date June, 07 Third one has two size and length Fourth has only length There are couple more variations and i need to parse all values. I have a regexp that pretty close except i can't figure out how to match patterns in different order without writing it twice. (?<size>\d{1,3}\[.,]\d{1,2}\s+(?:Mb)?)?\s? (?<length>(?:(?:01:)?\d{1,2}:\d{2}))?\s* (?<date>\d{2}\.\d{2}))? NOTE: that is only part of big regexp that forks fine already.
