• TortoiseSVN: how to set up projects on a existing directory structure of source code

  - by Steve

  I have an old pet project I want to revive (haven't had enough time for it last year - small kid - you know) - so restored old copy of my dev folder from archive, but since I have rebuilt my machine since when - I can't remember what needs to be done now. I installed the latest version of TortoiseSVN, and the existing directory structure from my old dev machine looks like: ProjectName *SubProject1 **branches ***1.1 ***1.2 **tags **trunk *SubProject2 **branches **1.0.3 **1.0.4 **1.0.5 **tags **trunk I tried "import project" but it ask for a url - don't know what to specify there ... can someone post a url to a good TortSVN tutorial - so I could set up my projects quickly (I guess I need to setup SubProject1 and SubProject2) - then I install AnkhSVN for VS2008 and will spend this Sunday coding like crazy while I still have some time ;-)

• Using terminal vs KDE in linux?

  - by Ke

  Hi Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal??? How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE? Any thoughts are much appreciated. I would love to understand the benefits but just cant seem to see them right now. Cheers Ke.

• Hybrid static/dynamic Google Map

  - by jonathanconway

  Ever noticed that when you go to maps.google.com and do a search (say, car wash), it renders a lot of results (represented by small circles) and a few prominent ones (seen as regular-size pins)? Notice how quickly it does this? From what I can tell from analyzing this in Firebug, much of this is generated on the server and sent to the client as a static image. However, it's still dynamic. You can still zoom in and out, or click on a result and see a dynamic InfoWindow rendered. Google have made the map quick and smooth using static images, while still making it flexible. Is there a way to do this kind of 'pre-loading' with my own Google Map (implemented with the Google Maps API)?

• Add a delay to OnContactDown events for Surface controls

  - by RTigger

  We're using the Controls.PreviewContactDown, PreviewContactUp, and PreviewContactChanged events to capture tagged items being placed, removed, and moved on the Surface, which works great in the Simulator application that comes with the surface. On an actual Surface if you moved a tagged item too quickly the cameras actually lose focus of the tag, assume it was removed, and then re-capture it when it stops moving. That provides a pretty poor experience for our clients. What I'm proposing is a way to override or create a new event that would respond to tagged item events, but not fire the event handler until after a delay... i.e. if "ContactUp" is fired, wait 100ms and THEN execute the event handler. Ideally we'd just be able to use an alternate attached property to define these event handlers, i.e. <Panel local:TagDown="TagDownEventHandler" /> And if we could get it to use ICommand objects instead of event handlers that'd be even better.

• trying to decide between asp.net and jsp

  - by Amir

  Hey Guys, I am wondering if anyone can shed some lights on the situation. I am about to start a project and trying to figure out what solution is best to go with asp.net or java jsp pages I have personally worked alot with .net and am really happy with the framework and Visual studio as IDE I find it easy to work with and there is a massive community support behind .net, i can get alot done quickly I have not every written anything use java jsp, there will be a learning curve here , so my experience is limited here. however after seeing jira i am very impressed with its capabilities, it has changed alot since the old days ( java 1.2 ) that i used to work with, and the fact that it runs under linux is a huge plus, so i am trying to decide is the learning curve, worth the price ? so given the situation above what would you recommended? Thanks, Amir

• Debugging asp.net with firefox and visual studio.net - very slow compared to IE

  - by john

  Debugging asp.net websites/web projects in visual studio.net 2005 with Firefox is loads slower than using IE. I've read something somewhere that there is a way of fixing this but i can't for the life of me find it again. Does anyone know what i'm on about and can point me in the right direction please? Cheers John edit sorry rob i haven't explained myself very well(again). I prefer Firefox for debugging (firebug etc) hitting F5 when debugging with IE the browser launches really quickly and clicking around my web application is almost instant and when a breakpont is hit i get to my code straight away with no delays. hitting F5 when debugging with FireFox the browser launches really slowly (ok i have plugins that slow FF loading) but clicking around my web application is really really slow and when a breakpoint is hit it takes ages to break into code. i swear i've read something somewhere that there is a setting in Firefox (about:config maybe?) that when changed to some magic setting sorts all this out.

• Customizing the Superfish drop-down menu

  - by Pieter

  I've been tinkering around with the excellent Superfish drop-down menu to fit my needs. Here's the result. Still, there are two oddities I need to fix. Since I changed the font family and font size used for the items in the menu bar, the drop-down menus are aligned incorrectly a few pixels lower than where they should be. Secondly, when I hover over a menu item that has a submenu, an arrow to the right is displayed but it's not as visible as it should be due to the light background color. Can I change this quickly without making a new arrow image?

• Can I use the TFS Object Model to interact with TFS via F#?

  - by Russell

  I am looking for some quick ways to do some (more) complex queries across who has what checked out and things like that (eg. which files have 1 person checked out). I have been learning F# over the last year or so and saw the potential to use both the functional aspects of F# to quickly create some useful and more complex TFS commands. I was wondering if anyone else has done this, or have any ideas on how I would go about doing this. PS: I am using TFS 2005. Thanks Russell

• 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?

• Automatically call httpservice.send

  - by Matt Robinson

  I have an application that displays the data from 3 xml files (auto generated from SQL table) using httpservices to get them. The first xml file is small and contains around 30 items, the second and thrid contain around 200-300 items each. The first dataset loads quickly and is invoked on creationComplete. The second and third are called from click events and take quite a few seconds to load. A user of the application will take at least 2-3 minutes reading the data from the first dataset so is there a way I can have the httpservice.send for the second and third xml files called automatically, straight after the first file has finished loading to be able to show the first dataset immediateley and get rid of the waiting times between dataset views. An answer doesnt need to be specific, just a point in the right direction would be great. All answers greatly appreciated Matt

• Umbraco or ASP.NET MVC

  - by StupidBoy

  I'm about to create a site that will act as public front site of company that sells furniture, but after user log in, he'll see much more options. Internal news, files to download, customized pricings, newsletters, etc. - stuff for wholesale clients. I want to make it quickly and maintain/extend it easily. I'm asp.net developer and while I could write it in python, php, whatever else (I know these too), I still prefer asp.net. I was thinking about umbraco, since it gives a real productivity boost and that I familiar with it ( and extending it). I've had a short romance with ASP.NET MVC, so I know what it's all about, but I would still spend some time learning it (but what a fun!). Of course, there's also webforms, but that's my last choice here. Last but not least to mention is the SEO. The question is, have anyone of you had similiar dilemma and what was your final choice?

• Parse HTML file to grab all ID and Classes for a CSS file

  - by iamfriendly

  Hey all, A short while ago, I'm fairly certain I came across an application (or perhaps a plugin for Coda - the IDE I use) which quickly parses a html document and then spits out all of the elements with IDs and Classes for me to use in a CSS file. Having fully 'got into' zen coding - using the wonderful TEA plugin for Coda, I'm now hot on the heels of this app/plugin again. I've tried and failed miserably at hunting through Google, but have come up completely empty handed. Does anyone know of anything which can do this? Happy New Year everyone!

• playing only part of a sound using FMOD

  - by carneades

  I'm trying to play only part of a sound using FMOD, say frames 50000-100000 of a 200000 frame file. I have found a couple of ways to seek forward (i.e. to start playback at frame 50000) but I have not found a way to make sure the sound stops playing at 100000. Is there any way FMOD can natively do this without having to add lbsndfile or the like into the picture? I should also mention that I am using the streaming option. I have to assume that these sounds are arbitrarily large and cannot be comfortably/quickly loaded into memory.

• Change Sprite Anchorpoint without moving it?

  - by Oscar Gomez

  I am trying to change my Sprite anchor point so that I can rotate over a 0.0f,0.0f anchorpoint. At first my object is rotation at the default anchor point (0.5f,0.5f). However later on I need it to rotate over a 0.0,0.0 AnchorPoint. The problem is I cannot change the anchor point and change the position accordingly, so it stays on the same position, without the object appearing to quickly move and reposition to its original point. Is there a way I can set the anchor point and the position of my Sprite at once, without it moving at all?. Thank you. -Oscar

• Qtestlib: QNetworkRequest not executed

  - by dzen

  I would like to test an asynchronous request to a webserver. For that purpose I'm creating a simple unittest to quickly try a few lines of code: void AsynchronousCall::testGet() { QNetworkAccessManager *nam = new QNetworkAccessManager(this); QUrl url("http://myownhttpserver.org"); QNetworkRequest req(url); this->connect(nam, SIGNAL(finished(QNetworkReply*)), this, SLOT(reqFinished(QNetworkReply *))); QNetworkReply *rep = nam->get(req); } void AsynchronousCall::reqFinished(QNetworkReply *rep) { qDebug() << rep->readAll(); qDebug() << "finshed"; } The problem is that reqFinished() is never reached. If I had a simple QEventLoop and and a loop.exec() just after the nam-get(req); the request is executed. Any hint ? Do I have to use a loop.exec() in my every unittests ?

• What makes you come back to stackoverflow every day? [closed]

  - by rmarimon

  I know this is not a programming question. Let's try to label it a programming community question so that it doesn't get closed. I've been wondering what makes the programming community so prone to helping others in stackoverflow. Is this something particular to programmers? Do you think lawyers and accountants would help other lawyers and programmers as we do? What makes you come back to stackoverflow every day? It would be great to have an answer per reason so that we can get the list of reasons. In my case, I come to stackoverflow to ask questions that I can't solve quickly, and to test how good I am when answering questions. So far I’ve failed miserably at trying to answer questions but it has helped me understand how little I know.

• Django BigInteger auto-increment field as primary key?

  - by Alex Letoosh

  Hi all, I'm currently building a project which involves a lot of collective intelligence. Every user visiting the web site gets created a unique profile and their data is later used to calculate best matches for themselves and other users. By default, Django creates an INT(11) id field to handle models primary keys. I'm concerned with this being overflown very quickly (i.e. ~2.4b devices visiting the page without prior cookie set up). How can I change it to be represented as BIGINT in MySQL and long() inside Django itself? I've found I could do the following (http://docs.djangoproject.com/en/dev/ref/models/fields/#bigintegerfield): class MyProfile(models.Model): id = BigIntegerField(primary_key=True) But is there a way to make it autoincrement, like usual id fields? Additionally, can I make it unsigned so that I get more space to fill in? Thanks!

• tetris rotation

  - by Samuel

  Hey, For university we're supposed to write a game (the language is modula2 little chance you know it). Each tetromino is defined through a central piece and 3 relative pieces, Now when it comes to rotation i just rotate the relative blocks (linear algebra). What i am asking myself is how to handle the rotations a user does when the piece has already "landed" because than the user has a little time left to move his pieve quickly into the desired position but in tetris versions all over the web you can "rotate over" other pieces, but i dont seem to get it with my rotation. Over what piece do i need to rotate? are there guidelines? Thanks

• Ruby on Rails: Model.all.each vs find_by_sql("SELECT * FROM model").each ?

  - by B_

  I'm fairly new to RoR. In my controller, I'm iterating over every tuple in the database. For every table, for every column I used to call SomeOtherModel.find_by_sql("SELECT column FROM model").each {|x| #etc } which worked fine enough. When I later changed this to Model.all(:select => "column").each {|x| #etc } the loop starts out at roughly the same speed but quickly slows down to something like 100 times slower than the the find_by_sql command. These calls should be identical so I really don't know what's happening. I know these calls are not the most efficient but this is just an intermediate step and I will optimize it more once this works correctly. Thanks!

• What is the best XPS WYSIWYG Editor that will output XAML?

  - by Simon

  I am looking for a WYSIWYG for XPS that will ouput the raw XAML. My intentions is use the tool for a way to quickly generate and test the XAML (of XPS documents) with the intention of then generating the same xaml in code and programmatically generating an XPS document. The same approach that many people use for generating html. Can anyone recommend any of the below products or suggest any others? Better yet does anyone know of a free XPS editor? NiXPS Edit $300USD http://www.nixps.com/nixps_edit_20.html XamlPad is free but also quite limited and does not really target XPS. Office System Power Tools is not WYSIWYG http://blogs.msdn.com/adrianford/archive/2008/07/03/visual-studio-and-xps-files.aspx XPS eXaminer 1.0 $399USD http://storefront.qualitylogic.com/p-16-qualitylogic-xps-examiner.aspx

• Facebook API friends_get is extremely slow

  - by IkimashoZ

  I have a PHP application running in iFrame mode. I am rendering an <fb:multi-friend-selector condensed="true"> inside of <fb:serverfbml> tags. This is inside a PHP file that calls a function that gets a list of user IDs using $facebook->api_client->friends_get();. The multi-friend selector renders just fine, but, when I leave the friend_get() call uncommented, the page takes between 15-20 seconds to load (confirmed with Firebug)! The goal is to limit the number of users displayed in the selector by building a list of user ids not to display, for use in the friend selector's exclude_ids parameter. And since it's "exclude_ids" and not "include_ids", I can't think of a way of getting around this api call. It seems to me there must be something I can do to make the api call faster, because I've seen friend selectors that load much more quickly.

• lazy loading images in UIScrollView

  - by idober

  I have an application the requires scrolling of many images. because I can not load all the images, and save it in the memory, I am lazy loading them. The problem is if I scroll too quickly, there are "black images" showing (images that did not manage to load). this is the lazy loading code: int currentImageToLoad = [self calculateWhichImageShowing] + imageBufferZone; [(UIView*)[[theScrollView subviews] objectAtIndex:0]removeFromSuperview]; PictureObject *pic = (PictureObject *)[imageList objectAtIndex:currentImageToLoad]; MyImageView *iv = [[MyImageView alloc] initWithFrame:CGRectMake(currentImageToLoad * 320.0f, 20.0f, 320.0f, 460)]; NSData *imageData = [NSData dataWithContentsOfFile:[pic imageName]]; [iv setupView:[UIImage imageWithData: imageData] :[pic imageDescription]]; [theScrollView insertSubview:iv atIndex:5]; [iv release]; this is the code inside scrollViewWillBeginDecelerating: [NSThread detachNewThreadSelector:@selector(lazyLoadImages) toTarget:self withObject:nil];

• How can I reprogram a USB "easy button"?

  - by Shawn Simon

  I have a USB "easy button"- is a USB cable attached to a large button. It appears as a keyboard to the computer. When I push the button, it sends the keys Start+R and then quickly types in a pre-configured URL. I am fairly certain that the company that produces these buttons sets the URL via some sort of software over USB. How could I reprogram the button myself? What sort of software would I need? Here is a link to the website: http://www.usbsmartbuttons.com/

• Fast permutation -> number -> permutation mapping algorithms

  - by ijw

  I have n elements. For the sake of an example, let's say, 7 elements, 1234567. I know there are 7! = 5040 permutations possible of these 7 elements. I want a fast algorithm comprising two functions: f(number) maps a number between 0 and 5039 to a unique permutation, and f'(permutation) maps the permutation back to the number that it was generated from. I don't care about the correspondence between number and permutation, providing each permutation has its own unique number. So, for instance, I might have functions where f(0) = '1234567' f'('1234567') = 0 The fastest algorithm that comes to mind is to enumerate all permutations and create a lookup table in both directions, so that, once the tables are created, f(0) would be O(1) and f('1234567') would be a lookup on a string. However, this is memory hungry, particularly when n becomes large. Can anyone propose another algorithm that would work quickly and without the memory disadvantage?

• Is there a standard site structure format?

  - by artlung

  Is there a standard site structure format? The use of this would be for export and import into a CMS or framework to define the urls, content, metadata for a website. Something tool agnostic would be the goal. JSON, YAML, XML, whatever. Maybe something like: { 'baseurl': 'http://example.com', 'site': [ {'slug': '/', 'title': 'ExampleCo. Inc.'}, {'slug': '/about', 'title': 'About Our Company'}, {'slug': '/services', 'title': 'Our Services'}, {'slug': '/products', 'title': 'Products'}, {'slug': '/products/purchase', 'title': 'Purchase Products Now'}, {'slug': '/products/downloads', 'title': 'Downloads'}, {'slug': '/contact', 'title': 'Contact Us'} ] } My thinking is that it would allow you to quickly populate a content management system or framework with a generic site navigational structure. Does something like this exist?
