  • Working with jTempalte and objects

    - by Dejan.S
    EDITSolved the one object question I had at first Hi I'm using jTemplate for the first time. I been reading and it's not that hard to use it BUT I just found a examaple on one object use. <script type="text/html" id="TemplateREsultTable"> <div style="background-color: #ccc">{$T.Email}</div> <div style="background-color: #ddd">{$T.Password}</div> </script> One question about jTempaltes I got is what is better to do them in htm file or script? Another thought I got, is jTemplate the way to go?

  • Awstats showing 404s for pages and objects I definitely don't have...

    - by Andrew Heath
    I have a HostGator site using Awstats and I've recently noticed the following 3 bizarre 404s: [address] [times] /images/wikimedia-button.png 1 /apple-touch-icon.png 1 /imgs/custom-space.gif 1 the first and third also carry referrers from within my site, but are 100% definitely absolutely not linked by any of my pages. I'm not too worried about it, seeing as each one has only popped up once. But I am concerned about why Awstats thinks one of my pages is referring what is apparently a wikipedia image, and why Steve Jobs is trying to haxx0r me (/joke) This is my first site to receive moderate daily usage, so I'm curious if these sorts of unique weird-o 404s just come with the territory, or if I should be double-checking something... Thanks!

  • phantom error "error parsing XML: unbound prefix"

    - by Brad Hein
    The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check). My environment is: Fedora Eclipse Platform Version: 3.4.2 Based on build id: 20090211-1700 My target is Android API level 5. The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error. Screenshot: http://i50.tinypic.com/2i89iee.jpg Who should I report this to?

  • Why my VPN doesn't work anymore?

    - by xx77aBs
    I have openvpn server running on debian lenny. There is only one client - and it is running Windows 7 64-bit. This has worked for few months without any problems. And now, let's say for the last 7 days, it doesn't work at all. I connect successfully from client to the server, but I can't access anything through VPN. I have set it up so that all internet traffic is routed through VPN, and now when I connect with the client, the client can't do anything on the net (open any webpage, ping google, anything ...). Can you help me to figure out what's wrong ? I don't know where to start. I've also tried to connect to another openvpn server (I've installed and configured openvpn on another server, and when I try to connect to it result is the same). So I think there's something wrong with client ...

  • Android USB driver for Xperia X10a

    - by mlohbihler
    I've been trying for a couple hours now, and have hit all of the sites Google found, but i cannot get the Android USB driver on my XP box to talk to my new Xperia X10a. I found the lines that some kind soul posted, and has been syndicated repeated, but they don't work for me. The idea is to add them to the Google.NTx86 and Google.NTamd64 sections of the android_winusb.inf file: ;Xperia X10 %SingleAdbInterface% = USB_Install, USB\VID_0FCE&PID_E12E %CompositeAdbInterface% = USB_Install, USB\VID_0FCE&PID_E12E&MI_01 I tried a number of variations of the first line, including "Sony Ericsson X10a", which is what XP shows me in both the "found new hardware" wizard and the device manager, but no luck. The result is always the same. Here are my steps: Plug in the phone via USB "found new hardware wizard" appears Choose "No, not this time" and "next" Choose "Install from a list or specific location..." and "next" Choose "Search for best driver...", check "Include this location...", and browse for the "usb_driver" folder in the Android SDK installation. Click "next" It does a quick search and then says "Cannot install this hardware", "... because the wizard cannot find the necessary software". I've tried more things that i can recall now, including deleting registry entries, but it just won't work. Any help would be appreciated at this point. Regards, m@

  • OPENGLES 2.0 equivalent of glorthof?

    - by Zippo
    Hi Guys, In my iphone app, i need to project 3d scene into the 2D coordinates of the screen for some calculations. My objects go through various rotations, translations and scaling. So i figured i need to multiply the vertices with ModelView matrix first, then i need to multiply it with the Orthogonal projection matrix. First of all am on the right track? I have the Model View Matrix, but need the projection matrix. Is there a glorthof equivalent in ES 2.0? PS: i am new to opengl. Thanks for your help. Zippo

  • Will OpenGL give me any FPS improvement over CoreAnimation for scrolling a large image?

    - by Ben Roberts
    Hi, I'm considering re-writing the menu system of my iPhone app to use Open GL just to improve the smoothness of scrolling a big image (480x1900px) across the screen. I'm looking at doing this as a way to improve on using the method/solution as described here (http://stackoverflow.com/questions/1443140/smoother-uiview). This solution was a big improvement over the previous implementation but it's still not perfect and as this is the first thing the user will see I'd like it to be as flawless as possible. Will switching to OpenGL give me the sort of smooth scrolling I'm looking for? I've stayed clear of OpenGL until now as this is my first app and core animation has handled everything else I've thrown at it well enough, would be good to know if this alternative implementation is likely to work! thanks

  • Math operations in nHibernate Criteria Query

    - by Richard Tasker
    Dear All, I am having troubles with a nHibernate query. I have a db which stores vehicle info, and the user is able to search the db by make, model, type and production dates. Make, model & type search is fine, works a treat, it is the productions dates I am having issues with. So here goes... The dates are stored as ints (StartMonth, StartYear, FinishMonth, FinishYear), when the end-user selects a date it is passed to the query as an int eg 2010006 (2010 * 100 + 6). below is part of the query I am using, FYI I am using Lambda Extensions. if (_searchCriteria.ProductionStart > 0) { query.Add<Engine>(e => ((e.StartYear * 100) + e.StartMonth) >= _searchCriteria.ProductionStart); } if (_searchCriteria.ProductionEnd > 0) { query.Add<Engine>(e => ((e.FinishYear * 100) + e.FinishMonth) <= _searchCriteria.ProductionEnd); } But when the query runs I get the following message, Could not determine member from ((e.StartYear * 100) + e.StartMonth) Any help would be great, Regards Rich

  • RIA Services Repository Save does not work!?

    - by Savvas Sopiadis
    Hello everybody! Doing my first SL4 MVVM RIA based application and i ran into the following situation: updating a record (EF4,NO-POCOS!!) in the SL-client seems to take place, but values in the dbms are unchanged. Debugging with Fiddler the message on save is (amongst others): EntityActions.nil? b9http://schemas.microsoft.com/2003/10/Serialization/Arrays^HasMemberChanges?^Id?^ Operation?Update I assume that this says only: hey! the dbms should do an update on this record, AND nothing more! Is that right?! I 'm using a generic repository like this: public class Repository<T> : IRepository<T> where T : class { IObjectSet<T> _objectSet; IObjectContext _objectContext; public Repository(IObjectContext objectContext) { this._objectContext = objectContext; _objectSet = objectContext.CreateObjectSet<T>(); } public IQueryable<T> AsQueryable() { return _objectSet; } public IEnumerable<T> GetAll() { return _objectSet.ToList(); } public IEnumerable<T> Find(Expression<Func<T, bool>> where) { return _objectSet.Where(where); } public T Single(Expression<Func<T, bool>> where) { return _objectSet.Single(where); } public T First(Expression<Func<T, bool>> where) { return _objectSet.First(where); } public void Delete(T entity) { _objectSet.DeleteObject(entity); } public void Add(T entity) { _objectSet.AddObject(entity); } public void Attach(T entity) { _objectSet.Attach(entity); } public void Save() { _objectContext.SaveChanges(); } } The DomainService Update Method is the following: [Update] public void UpdateCulture(Culture currentCulture) { if (currentCulture.EntityState == System.Data.EntityState.Detached) { this.cultureRepository.Attach(currentCulture); } this.cultureRepository.Save(); } I know that the currentCulture-Entity is detached. What confuses me (amongst other things) is this: is the _objectContext still alive? (which means it "will be"??? aware of the changes made to record, so simply calling Attach() and then Save() should be enough!?!?) What am i missing? Development Environment: VS2010RC - Entity Framework 4 (no POCOs) Thanks in advance

  • Core Location Best Placement and User Interruption

    - by b.dot
    Hi All, My application uses Core Location in three different views. It's working perfectly. In my first view, I subclass the CLLocationManager and use protocol methods for location updates to my calling class. Before I install the framework and code in my other classes, I was wondering: Is the protocol method the best way? What happens to the Core Location execution if the user exits the view or quits the app while it's trying to get a location fix? Is the location task terminated with the GPS system turned off immediately? If the user simply switches to another view, is it OK to assume that I can start Core Location in the next view without regard to the last? Where should the first update location call be placed. Should the application delegate instantiate the CLLocation Manager class using protocol so that it can update any of the views chosen or should each class instantiate the manager. Any feedback would be appreciated. Thanks.

  • Background processing in rails

    - by hashpipe
    Hi, This might seem like a FAQ on stackoverflow, but my requirements are a little different. While I have previously used BackgroundRB and DJ for running background processes in ruby, my requirement this time is to run some heavy analytics and mathematical computations on a huge set of data, and I need to do this only about the first 15 days of the month. Going by this, I am tempted to use cron and run a ruby script to accomplish this goal. What I would like to know / understand is: 1 - Is using cron a good idea (cause I'm not a system admin, and so while I have basic idea of cron, I'm not overly confident of doing it perfectly) 2 - Can we somehow modify DJ to run only on the first 15 days of the month (with / without using cron), and then just stop and exit once all the jobs in the queue for the day are over (don't want it to ping the DB every time for a new job...whatever the jobs will be in the queue when DJ starts, that will be all). I'm not sure if I have put the question in the right manner, but any help in this direction will be much appreciated. Thanks

  • XCode Intellisense Question

    - by Cody C
    I've always seem to work around this lack of knowledge but I thought I would ask the community. I hope this question will make sense. In XCode, when I call a function that has several parameter the intellisense pops up. When I hit TAB the first time, it takes me directly to the first parameter. How do I get to the next parameter easily. If I hit TAB again, it puts an actual TAB in the line. For the last month I've been using arrow keys but I figured there must be a keyboard shortcut.

  • CSS Attribute Content Selector multiple declarations

    - by Dave
    I have this in my CSS: div#headwrap ul li a[href*="dev"] {background: #034769}; div#headwrap ul li a[href*="music"] {background: #A61300}; div#headwrap ul li a[href*="opinion"] {background: #b2d81e}; div#headwrap ul li a[href*="work"] {background: #ffc340}; So, my expected behavior is that where a link (a) within a list item (li) inside a unordered list (ul) inside a div with id "headwrap" has an href that contains "dev", the link will have a background color of #034769. If the link has an href that contains "music" it will have a background color of #A61300, and so on. However, what I am seeing is that the rule is only correctly applied to "dev". If I reorder the CSS declarations (putting music first, for instance), it only gets applied to "music". I'm testing in Firefox and Chrome, both are doing the same thing. Only the first one is applied. Anyone have any ideas why?

  • Scheme early "short circuit return"?

    - by Suan
    I'm trying to find out how I can do an "early return" in a scheme procedure without using a top-level if or cond like construct. (define (win b) (let* ((test (first (first b))) (result (every (lambda (i) (= (list-ref (list-ref b i) i) test)) (enumerate (length b))))) (when (and (not (= test 0)) result) test)) 0) For example, in the code above, I want win to return test if the when condition is met, otherwise return 0. However, what happens is that the procedure will always return 0, regardless of the result of the when condition. The reason I am structuring my code this way is because in this procedure I need to do numerous complex checks (multiple blocks similar to the let* in the example) and putting everything in a big cond would be very unwieldy.

  • Lucene: Question of score caculation with PrefixQuery

    - by Keven
    Hi, I meet some problem with the score caculation with a PrefixQuery. To change score of each document, when add document into index, I have used setBoost to change the boost of the document. Then I create PrefixQuery to search, but the result have not been changed according to the boost. It seems setBoost totally doesn't work for a PrefixQuery. Please check my code below: @Test public void testNormsDocBoost() throws Exception { Directory dir = new RAMDirectory(); IndexWriter writer = new IndexWriter(dir, new StandardAnalyzer(Version.LUCENE_CURRENT), true, IndexWriter.MaxFieldLength.LIMITED); Document doc1 = new Document(); Field f1 = new Field("contents", "common1", Field.Store.YES, Field.Index.ANALYZED); doc1.add(f1); doc1.setBoost(100); writer.addDocument(doc1); Document doc2 = new Document(); Field f2 = new Field("contents", "common2", Field.Store.YES, Field.Index.ANALYZED); doc2.add(f2); doc2.setBoost(200); writer.addDocument(doc2); Document doc3 = new Document(); Field f3 = new Field("contents", "common3", Field.Store.YES, Field.Index.ANALYZED); doc3.add(f3); doc3.setBoost(300); writer.addDocument(doc3); writer.close(); IndexReader reader = IndexReader.open(dir); IndexSearcher searcher = new IndexSearcher(reader); TopDocs docs = searcher.search(new PrefixQuery(new Term("contents", "common")), 10); for (ScoreDoc doc : docs.scoreDocs) { System.out.println("docid : " + doc.doc + " score : " + doc.score + " " + searcher.doc(doc.doc).get("contents")); } } The output is : docid : 0 score : 1.0 common1 docid : 1 score : 1.0 common2 docid : 2 score : 1.0 common3

  • OCS presence in SharePoint AJAX-based web part

    - by Maksym Ozerov
    I'm currently implementing AJAX-based web part which displays search result. This search result has user names and opposite to each name I'm rendering the OCS presence indicator. This indicator works fine in IE6 but I can't get it to work in IE7/8. Basically the problem in IE7/8 is that OCS is rendered but when you mouse over it nothing is shown. If you try to scroll page down then mouse over the OCS icon you will see the OCS actions menu in the bottom of the page instead of seeing it on the opposite to the user name. My AJAX-based web part uses jQuery post method to make a request to the server and receives json which is then rendered to the div. My HTML for the user name looks like this: <nobr> <span> <a target='_blank' href='/ViewExpert.aspx?uid=4'>Some Expert</a> <img height='1' width='3' border='0' alt='' src='/_layouts/images/blank.gif'><a class='ms-imnlink' onclick='IMNImageOnClick();return false;' href='javascript:'> <img height='12' width='12' border='0' id='3' ShowOfflinePawn='1' type='smtp' sip='[email protected]' src='/_layouts/images/blank.gif' valign='middle' name='imnmark' alt='No presence information' title=''> </a> </span> </nobr> After the HTML above is rendered on the page I call the following two lines of code: //have to reset this value, otherwise ProcessImn() fails after next AJAX request imnCount = 0; ProcessImn(); Any ideas why it doesn't work in IE7/8?

  • Explain BFS and DFS in terms of backtracking

    - by HH
    Wikipedia about DFS Depth-first search (DFS) is an algorithm for traversing or searching a tree, tree structure, or graph. One starts at the root (selecting some node as the root in the graph case) and explores as far as possible along each branch before backtracking. So is BFS? "an algorithm that choose a starting node, checks all nodes -- backtracks --, chooses the shortest path, chose neighbour nodes -- backtracks --, chose the shortest path -- finally finds the optimal path because of traversing each path due to continuos backtracking. Regex, find's pruning -- backtracking? The term backtracking confuseses due to its variety of use. UNIX find's pruning an SO-user explained with backtracking. Regex Buddy uses the term "catastrophic backtracking" if you do not limit the scope of your Regexes. It seems to be too wide umbrella-term. So: how do you define "Backtracking" GRAPH-theoretically? what is "backtracking" in BFS and DFS?

  • Installing php-module using port on osx lion. It works from command line but not from apache

    - by Lorraine Bernard
    I installed php5-intl on my osx lion. It seems to work properly on command line mode because if I try to run the following script (1): $fmt = datefmt_create( "en_US" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGORIAN ); echo "First Formatted output is ".datefmt_format( $fmt , 0)."\n"; > php -m |grep intl intl > php test.php First Formatted output is Wednesday, December 31, 1969 4:00:00 PM Pacific Standard Time But if I try to sun the same from my apache (after sudo apachectl restart) I get the following error: > tail /private/var/log/apache2/error_log PHP Fatal error: Call to undefined function datefmt_create() in P.S.: I also added the following line to my php.ini extension_dir = "/opt/local/lib/php/extensions/no-debug-non-zts-20090626" ll /opt/local/lib/php/extensions/no-debug-non-zts-20090626 total 848 -rwxr-xr-x 1 root 261712 7 May 10:54 xdebug.so -rwxr-xr-x 1 root 168912 31 May 19:53 intl.so

  • Hooking a Stacktrace in Delphi 2009

    - by Jim McKeeth
    The Exception class in Delphi 2009 received a number of new features. A number of them are related to getting a stacktrace: property StackTrace: string *read* GetStackTrace; property StackInfo: Pointer read FStackInfo; class var GetExceptionStackInfoProc: function (P: PExceptionRecord): Pointer; class var GetStackInfoStringProc: function (Info: Pointer): string; class var CleanUpStackInfoProc: procedure (Info: Pointer); Has anyone used these to obtain a stack trace yet? Yeah, I know there are other ways to get a stack trace, but if it is supported natively in the Exception class I would rather leverage that. Update: There is an interest blog post about this. Covers it in a lot of depth.

  • HttpModule Init method is called several times - why?

    - by MartinF
    I was creating a http module and while debugging I noticed something which at first (at least) seemed like weird behaviour. When i set a breakpoint in the init method of the httpmodule i can see that the http module init method is being called several times even though i have only started up the website for debugging and made one single request (sometimes it is hit only 1 time, other times as many as 10 times). I know that I should expect several instances of the HttpApplication to be running and for each the http modules will be created, but when i request a single page it should be handled by a single http application object and therefore only fire the events associated once, but still it fires the events several times for each request which makes no sense - other than it must have been added several times within that httpApplication - which means it is the same httpmodule init method which is being called every time and not a new http application being created each time it hits my break point (see my code example at the bottom etc.). What could be going wrong here ? is it because i am debugging and set a breakpoint in the http module? It have noticed that it seems that if i startup the website for debugging and quickly step over the breakpoint in the httpmodule it will only hit the init method once and the same goes for the eventhandler. If I instead let it hang at the breakpoint for a few seconds the init method is being called several times (seems like it depends on how long time i wait before stepping over the breakpoint). Maybe this could be some build in feature to make sure that the httpmodule is initialised and the http application can serve requests , but it also seems like something that could have catastrophic consequences. This could seem logical, as it might be trying to finish the request and since i have set the break point it thinks something have gone wrong and try to call the init method again ? soo it can handle the request ? But is this what is happening and is everything fine (i am just guessing), or is it a real problem ? What i am specially concerned about is that if something makes it hang on the "production/live" server for a few seconds a lot of event handlers are added through the init and therefore each request to the page suddenly fires the eventhandler several times. This behaviour could quickly bring any site down. I have looked at the "original" .net code used for the httpmodules for formsauthentication and the rolemanagermodule etc but my code isnt any different that those modules uses. My code looks like this. public void Init(HttpApplication app) { if (CommunityAuthenticationIntegration.IsEnabled) { FormsAuthenticationModule formsAuthModule = (FormsAuthenticationModule) app.Modules["FormsAuthentication"]; formsAuthModule.Authenticate += new FormsAuthenticationEventHandler(this.OnAuthenticate); } } here is an example how it is done in the RoleManagerModule from the .NET framework public void Init(HttpApplication app) { if (Roles.Enabled) { app.PostAuthenticateRequest += new EventHandler(this.OnEnter); app.EndRequest += new EventHandler(this.OnLeave); } } Do anyone know what is going on? (i just hope someone out there can tell me why this is happening and assure me that everything is perfectly fine) :) UPDATE: I have tried to narrow down the problem and so far i have found that the Init method being called is always on a new object of my http module (contary to what i thought before). I seems that for the first request (when starting up the site) all of the HttpApplication objects being created and its modules are all trying to serve the first request and therefore all hit the eventhandler that is being added. I cant really figure out why this is happening. If i request another page all the HttpApplication's created (and their moduless) will again try to serve the request causing it to hit the eventhandler multiple times. But it also seems that if i then jump back to the first page (or another one) only one HttpApplication will start to take care of the request and everything is as expected - as long as i dont let it hang at a break point. If i let it hang at a breakpoint it begins to create new HttpApplication's objects and starts adding HttpApplications (more than 1) to serve/handle the request (which is already in process of being served by the HttpApplication which is currently stopped at the breakpoint). I guess or hope that it might be some intelligent "behind the scenes" way of helping to distribute and handle load and / or errors. But I have no clue. I hope some out there can assure me that it is perfectly fine and how it is supposed to be?

  • Smooth Error in qplot from ggplot2

    - by Jared
    I have some data that I am trying to plot faceted by its Type with a smooth (Loess, LM, whatever) superimposed. Generation code is below: testFrame <- data.frame(Time=sample(20:60,50,replace=T),Dollars=round(runif(50,0,6)),Type=sample(c("First","Second","Third","Fourth"),50,replace=T,prob=c(.33,.01,.33,.33))) I have no problem either making a faceted plot, or plotting the smooth, but I cannnot do both. The first three lines of code below work fine. The fourth line is where I have trouble: qplot(Time,Dollars,data=testFrame,colour=Type) qplot(Time,Dollars,data=testFrame,colour=Type) + geom_smooth() qplot(Time,Dollars,data=testFrame) + facet_wrap(~Type) qplot(Time,Dollars,data=testFrame) + facet_wrap(~Type) + geom_smooth() It gives the following error: Error in [<-.data.frame(*tmp*, var, value = list(NA = NULL)) : missing values are not allowed in subscripted assignments of data frames What am I missing to overlay a smooth in a faceted plot? I could have sworn I had done this before, possibly even with the same data.

  • Pair programming: How should the pairs be chosen?

    - by Jon Seigel
    This topic has been covered peripherally in bits and pieces in some of the other pair-programming questions, but I want to (a) consolidate this knowledge into a separate question, and, most importantly, (b) go into much more depth on the subject. From the perspective of being an effective manager, how should pairs be arranged for pair programming to maximize both the happiness and productivity of the overall team? Some ideas to get started: Should two people never be paired (because of personalities, for example)? How much overlap in skillsets is needed? How much disconnect in skillsets is too much to overcome? (No two people will overlap 100%, and a disconnect in skills can be very beneficial to both people.) Should everyone pair with everyone else on a fixed/rotating basis? Should certain pairs be arranged to accomplish specific tasks? How important a role does HR play when growing or reorganizing the team?

  • Adding lengths of strings together in Ruby

    - by ppreyer
    I'm trying to write a program that takes the length of my first, middle, and last names individually and then adds the total amount of letters up in the end. My answer keeps on being 666 instead of 18. Here is the code I have written: puts 'What is your first name?' firstName = gets.chomp realFirstName = firstName.length.to_i puts 'What is your middle name?' middleName = gets.chomp realMiddleName = middleName.length.to_i puts 'What is your last name?' lastName = gets.chomp realLastName = lastName.length.to_i puts 'Did you know there are ' + realFirstName.to_s + realMiddleName.to_s + realLastName.to_s + ' letters in your name?' Just wondering where I went wrong.
