  • MKAnnotations are being made successfully, however they sometimes fail to render on MKMapView

    - by jtkendall
    I'm working on an iPhone app using the 3.1.3 SDK, my app finds the users current location, displays it on a MKMapView and then finds nearby locations and renders them as MKAnnotations. My code is working, however sometimes the nearby annotations do not appear on the map. They are still being made as I see the correct data in the console (from NSLog which runs just after the annotations are made). When it fails is completely random, it could be the 5th time I've hit "Build and Run" for the day, or the 500th it doesn't appear to have any pattern and doesn't throw any type of error, it just doesn't add the annotations to the MapView. This is the method called for each nearby location to add the MKAnnotation. - (void)addPinsWithLocation:(NSDictionary *)spot { CLLocationCoordinate2D location; location.longitude = [[spot objectForKey:@"spot_longitude"] doubleValue]; location.latitude = [[spot objectForKey:@"spot_latitude"] doubleValue]; PlaceMarks *placemark = [[PlaceMarks alloc] initWithCoordinate:location title:[spot objectForKey:@"spot_name"] subtitle:@""]; NSLog(@"Adding Pin for Location: '%@' at %f, %f", [spot objectForKey:@"spot_name"], location.latitude, location.longitude); [mapView addAnnotation:placemark]; } Any ideas on how to get MKAnnotations to always show?

  • Designing a silverlight dashboard with mef - is it possible? (with dynamic loading of xaps)

    - by Tim Robbin
    Hello! I am just trying to wrap my head around MEF. And as I am really going to love it ( I guess ) I started my first sample project and immediatly stumbled into a big problem and now I am asking myself if I can use MEF for my scenario at all and that is the following: Imagine that one got some kind of dashboard with, let's say, five regions and above each region there are two comboboxes. The values in the first combobox represent different possible views (for example, chartControl, tableControl, pictureControl, ...) and the values of the second combobox represents the different data sources for the currently selected control. As the controls are very big in size one wants to download them as needed. If the user selects one comboboxitem the corresponding control xap should be loaded and displayed in this specific region. If the user selectes another control in the same combobox the control should be removed from the visualtree and the next control should be downloaded and displayed. If the user changes the selection in a different combobox the corresponding control should be loaded again only in this specific region, with perhaps different data. And to make it a little more interesting - as this is some kind of dashboard one can change the layout from five regions to - for example - ten regions. I've seen the video "MVVM with MEF in Silverlight Video Tutorial Part 2: Plugins and Metadata" ( http://csharperimage.jeremylikness.com/2010/03/mvvm-with-mef-in-silverlight-video_09.html ) but he is using an ItemsControl and is working with Visibility and he only got ONE region. So I think that this technique is not working for me... Puh, I hope I could make myself clear! Thanks a lot for any piece of information!!! Greetings, Tim.

  • OpenGL Colour Interpolation

    - by Will-of-fortune
    I'm currently working on an little project in C++ and OpenGL and am trying to implement a colour selection tool similar to that in photoshop, as below. However I am having trouble with interpolation of the large square. Working on my desktop computer with a 8800 GTS the result was similar but the blending wasn't as smooth. This is the code I am using: GLfloat swatch[] = { 0,0,0, 1,1,1, mR,mG,mB, 0,0,0 }; GLint swatchVert[] = { 400,700, 400,500, 600,500, 600,700 }; glVertexPointer(2, GL_INT, 0, swatchVert); glColorPointer(3, GL_FLOAT, 0, swatch); glDrawArrays(GL_QUADS, 0, 4); Moving onto my laptop with Intel Graphics HD 3000, this result was even worse with no change in code. I thought it was OpenGL splitting the quad into two triangles, so I tried rendering using triangles and interpolating the colour in the middle of the square myself but it still doesnt quite match the result I was hoping for. Any help would be appreciated. Thanks.

  • When is a good time to start thinking about scaling?

    - by Slokun
    I've been designing a site over the past couple days, and been doing some research into different aspects of scaling a site horizontally. If things go as planned, in a few months (years?) I know I'd need to worry about scaling the site up and out, since the resources it would end up consuming would be huge. So, this got me to thinking, when is the best time to start thinking about, and designing for, scalability? If you start too early on, you could easily over complicate your design, and make it impossible to actually build. You could also get too caught up in the details, the architecture, whatever, and wind up getting nothing done. Also, if you do get it working, but the site never takes off, you may have wasted a good chunk of extra effort. On the other hand, you could be saving yourself a ton of effort down the road. Designing it from the ground up to be big would make it much easier later on to let it grow big, with very little rewriting going on. I know for what I'm working on, I've decided to make at least a few choices now on the side of scaling, but I'm not going to do a complete change of thinking to get it to scale completely. Notably, I've redesigned my database from a conventional relational design to one similar to what was suggested on the Reddit site linked below, and I'm going to give memcache a try. So, the basic question, when is a good time to start thinking or worrying about scaling, and what are some good designs, tips, etc. for when doing so? A couple of things I've been reading, for those who are interested: http://www.codinghorror.com/blog/2009/06/scaling-up-vs-scaling-out-hidden-costs.html http://highscalability.com/blog/2010/5/17/7-lessons-learned-while-building-reddit-to-270-million-page.html http://developer.yahoo.com/performance/rules.html

  • Dynamically created controls and the ASP.NET page lifecycle

    - by Dirk
    I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls. protected override void OnLoad(EventArgs e) { base.OnLoad(e); RenderDynamicControls() } private void RenderDynamicControls(){ //1. call service layer to retrieve form definition //2. create and add controls to page container } I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code: protected void MyButton_Click(object sender, EventArgs e) { RenderDynamicControlsALittleDifferently() } private void RenderDynamicControlsALittleDifferently() (){ //1. clear all controls from the page container added in RenderDynamicControls() //2. call service layer to retrieve form definition //3. create and add controls to page container } My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid. On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax. Any code/advice that make that transition easier would be much appreciated. Thanks

  • How do you make a static sprite be a child of another sprite in cocos2D while using SpaceManager

    - by JJBigThoughts
    I have two static (STATIC_MASS) SpaceManager sprites. One is a child of the other - by which I mean that one sort of builds up the other one, but although the child's images shows up in the right place, the child doesn't seem to exists in the chipmunk physics engine, like I would expect. In my case, I have a backboard (rectangular sprite) and a hoop (a circular sprite). Since I might want to move the backboard, I'd like to attach the hoop to backboard so that the hoop automatically moves right along with the backboard. Here, we see a rotating backboard with attached hoop. It looks OK on the screen, but other objects only bounce off the backboard but pass right through the hoop (in a bad sense of the term). What doesn't my child sprite seem to exist in the physics engine? // Add Backboard cpShape *shapeRect = [smgr addRectAt:cpvWinCenter mass:STATIC_MASS width:200 height:10 rotation:0.0f ];// We're upgrading this cpCCSprite * cccrsRect = [cpCCSprite spriteWithShape:shapeRect file:@"rect_200x10.png"]; [self addChild:cccrsRect]; // Spin the static backboard: http://stackoverflow.com/questions/2691589/how-do-you-make-a-sprite-rotate-in-cocos2d-while-using-spacemanager // Make static object update moves in chipmunk // Since Backboard is static, and since we're going to move it, it needs to know about spacemanager so its position gets updated inside chipmunk. // Setting this would make the smgr recalculate all static shapes positions every step // cccrsRect.integrationDt = smgr.constantDt; // cccrsRect.spaceManager = smgr; // Alternative method: smgr.rehashStaticEveryStep = YES; smgr.rehashStaticEveryStep = YES; // Spin the backboard [cccrsRect runAction:[CCRepeatForever actionWithAction: [CCSequence actions: [CCRotateTo actionWithDuration:2 angle:180], [CCRotateTo actionWithDuration:2 angle:360], nil] ]]; // Add the hoop cpShape *shapeHoop = [smgr addCircleAt:ccp(100,-45) mass:STATIC_MASS radius: 50 ]; cpCCSprite * cccrsHoop = [cpCCSprite spriteWithShape:shapeHoop file:@"hoop_100x100.png"]; [cccrsRect addChild:cccrsHoop]; This is only half working for me. Note: SpaceManager is a toolkit for working with cocos2D-iphone

  • Bidirectional/Loopback UDP in .net

    - by Jason Williams
    I've got an app that needs to transmit and receive on the same port. This can happen in two cases: Where the PC is talking to a piece of remote hardware. It "replies to sender", so the datagrams come back in to my PC via the sending port. Where the PC is talking to itself (loopback mode) for testing and demoing (a test app feeds fake data into our main app via UDP). This only seems to fail when trying to achieve loopback. The only way I can get it working is to ensure that the receiver is set up first - something I cannot guarantee. Can anyone help narrow down my search by suggesting a "correct" way to implement the UdpClient(s) to handle the above situations reliably? (The only solution that I've found to work reliably with the remote hardware is to use a single UdpClient in a bidirectional manner, although I'm working with legacy code that may be influencing that finding. I've tried using two UdpClients, but they step on each others toes - In some cases, once one client is started up, the other client cannot connect. With ExclusiveAddressUse/ReuseAddress set up to allow port sharing, I can almost get it to work, apart from the receiver having to start first)

  • changing sounds when objects meet

    - by blacksheep
    i'd like to change sounds when tapping on an image and drag another image over several others. it is not working properly: the "MoveImage" is not dragable, the tapping is working outside the "TouchImage" and the sounds do not change when tapping on it. (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if(((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)))) { [sound_E play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)))) { [sound_F play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)))) { [sound_D play]; } if (((CGRectContainsPoint(myTouchImage.frame, location)), (CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)))) { [sound_Dis play]; } } (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; if (CGRectContainsPoint(myMoveImage.frame, location)){ CGPoint yLocation = CGPointMake(myMoveImage.center.x,location.y); myMoveImage.center = yLocation; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_1.frame)) { E_NOTE.text = @"E"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_2.frame)) { F_NOTE.text = @"F"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_3.frame)) { D_NOTE.text = @"D"; } if(CGRectIntersectsRect(myMoveImage.frame,myImage_4.frame)) { Dis_NOTE.text = @"D#"; } }

  • Where to post code for open source usage?

    - by Douglas
    I've been working for a few weeks now with the Google Maps API v3, and have done a good bit of development for the map I've been creating. Some of the things I've done have had to be done to add usability where there previously was not any, at least not that I could find online. Essentially, I made a list of what had to be done, searched all over the web for the ways to do what I needed, and found that some were not(at the time) possible(in the "grab an example off the web" sense). Thus, in my working on this map, I have created a number of very useful tools, which I would like to share with the development community. Is there anywhere I could use as a hub, apart from my portfolio ( http://dougglover.com ), to allow people to view and recycle my work? I know how hard it can be to need to do something, and be unable to find the solution elsewhere, and I don't think that if something has been done before, it should necessarily need to be written again and again. Hence open source code, right? Firstly, I was considering coming on here and asking a question, and then just answering it. Problem there is I assume that would just look like a big reputation grab. If not, please let me know and I'll go ahead and do that so people here can see it. Other suggestions appreciated. Some stuff I've made: A (new and improved) LatLng generator Works quicker, generates LatLng based on position of a draggable marker Allows searching for an address to place the marker on/near the desired location(much better than having to scroll to your location all the way from Siberia) Since it's a draggable marker, double-clicking zooms in, instead of creating a new LatLng marker like the one I was originally using The ability to create entirely custom "Smart Paths" Plot LatLng points on the map which connect to each other just like they do using the actual Google Maps Using Dijkstra's algorithm with Javascript, the routing is intelligent and always gives the shortest possible route, using the points provided Simple, easy to read multi-dimensional array system allows for easily adding new points to the grid Any suggestions, etc. appreciated.

  • Where did Pylons beautiful error handling go? Using Nginx + Paster + Flup#fcgi_thread

    - by Tony
    I need to run my development through nginx due to some complicated subdomain routing rules in my pylons app that wouldn't be handled otherwise. I had been using lighttpd + paster + Flup#scgi_thread and the nice error reporting by Pylons had been working fine in that environment. Yesterday I recompiled Python and MySQL for 64bit, and also switched to Ngix + paster + Flup#fcgi_thread for my development environment. Everything is working great, but I miss the fancy error reports. This is what I get now, and it is a mess compared to what I got used to: http://drp.ly/Iygeg . And here are the pylons/nginx configs. Pylons: [server:main] use = egg:Flup#fcgi_thread host = 0.0.0.0 port = 6500 Nginx: location / { #include /usr/local/nginx/conf/fastcgi.conf; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param QUERY_STRING $query_string; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_pass_header Authorization; fastcgi_intercept_errors off; fastcgi_pass 127.0.0.1:6500; }

  • Building Paypal based membership website - total noob - would appreciate help

    - by Ali
    this is a follow up on my question on paypal integration. I'm working ona membership site for racing fans. My membership site has 3 membership levels - free, gold and premium. When a user signs up he/she can gets a free membership on the spot but has the option to upgrade to a gold membership for 4 Dollars a month or a premium membership for 10 Dollars a month. I've gone through the paypal integration guide a few times though and have a vague understanding of how to get this to work. I think the recurring payments option would be fine enough - however I don't know how do I implement this in my system. Like when a user decides to go for a paid account i.e. Gold or premium from basic - what should I do on both my code side and on the paypal account side - I'd really appreciate if anyone would outline what I'd have to do here. Plus when a user decides to upgrade from lets say a Gold to a premium account - there is the issue of computing how much should be charged to upgrade his/her account eg: a user has been billed for 4 dollars and the next day opts to go for a premium account so assuming that the surplus for the rest of the month is 5 dollars and further from that all payments would be recurring 10 dollars monthly - how do I implement this? And in case a user decides to downgrade from a premium account of 10 dollars a month to a gold account of 4 dollars a month - how do I handle the surplus which would have to be refunded for that month alone and changing the membership? And like wise if someone wishes to cancel membership and go to having a free account - how do I refund whatever is owed and cancel the subscription. I'm sorry if it sounds like I'm asking to be spoon fed :( I'm quite new to this and this is for a client and I would really appreciate all the help here and really have to get this working right. Thanks again everyone - waiting for all your replies.

  • When to choose which machine learning classifier?

    - by LM
    Suppose I'm working on some classification problem. (Fraud detection and comment spam are two problems I'm working on right now, but I'm curious about any classification task in general.) How do I know which classifier I should use? (Decision tree, SVM, Bayesian, logistic regression, etc.) In which cases is one of them the "natural" first choice, and what are the principles for choosing that one? Examples of the type of answers I'm looking for (from Manning et al.'s "Introduction to Information Retrieval book": http://nlp.stanford.edu/IR-book/html/htmledition/choosing-what-kind-of-classifier-to-use-1.html): a. If your data is labeled, but you only have a limited amount, you should use a classifier with high bias (for example, Naive Bayes). [I'm guessing this is because a higher-bias classifier will have lower variance, which is good because of the small amount of data.] b. If you have a ton of data, then the classifier doesn't really matter so much, so you should probably just choose a classifier with good scalability. What are other guidelines? Even answers like "if you'll have to explain your model to some upper management person, then maybe you should use a decision tree, since the decision rules are fairly transparent" are good. I care less about implementation/library issues, though. Also, for a somewhat separate question, besides standard Bayesian classifiers, are there 'standard state-of-the-art' methods for comment spam detection (as opposed to email spam)? [Not sure if stackoverflow is the best place to ask this question, since it's more machine learning than actual programming -- if not, any suggestions for where else?]

  • How to remove Modules from a Intellij Maven Project permanently?

    - by herpnderpn
    I am currently working on a larger scale Maven-based project in IntelliJIdea 12.1.6 Ultimate. I have been working with IntelliJIdea since about 5 months. An included module has dependencies on another module. The dependent module's source was also part of my project until recently. Since I removed the dependent module from my project, I get compile errors whenever I am trying to compile the source without maven. The pom.xml of removed modules in Intellij seem to be placed onto the Settings-Maven-Ignored Files. I cant seem to remove it from there, only check or uncheck it. It's not possible to include the module again since IntelliJ will say its still under Ignored Files. 2 ways allow me to compile again: Uncheck the pom from Ignored files, which will include the module again in my project. Or delete the source of the dependent project, so my project will load the dependent module from the maven repository. But whenever I update my project from svn, the source of the dependent module is restored (I don't know why this even happens since its not part my project) and the cycle begins anew. I googled this for a while since it gets really annoying. It became a problem with several excluded modules. I could rebuild the intellij-project but since a lot of IntelliJ settings were made (not related to the problem) I would rather solve this. Any help is appreciated, I guess I must be missing something

  • StructureMap and injecting IEnumerable<T>

    - by GiddyUpHorsey
    I'm new to StructureMap and have some existing code that I'm working with that uses StructureMap 2.5.4. There is a class that is constructed using StructureMap that has a constructor that takes IEnumerable<TCar> as a parameter. The registry has the following code. Scan(x => { x.TheCallingAssembly(); x.WithDefaultConventions(); x.AddAllTypesOf<ICar>(); } ); ForRequestedType<IEnumerable<ICar>>().TheDefault.Is.ConstructedBy( x => ObjectFactory.GetAllInstances<ICar>()); I'm writing a unit test and have obtained a nested container off the ObjectFactory and have injected an instance using the Inject method. One of the instances of ICar should receive the injected type in its constructor. However it wasn't working and I tracked that down to the ObjectFactory.GetAllInstances() call which doesn't use my nested container. How can I get this to work? I also read about StructureMap autowiring arrays and IEnumerable instances but I couldn't get it to work. Is there a better way to rewrite the above registry code so that an instance of IEnumerable<TCar> will be created and use the injected type from my nested container?

  • Porting some PHP to ColdFusion

    - by Oscar Godson
    OK, I'm working with converting some very basic PHP to port to a dev server where the client only has CF. Ive never worked with it, and I just need to know how to port a couple things: <?php $pageTitle = 'The City That Works'; $mainCSSURL = 'header_url=../images/banner-home.jpg&amp;second_color=484848&amp;primary_color=333&amp;link_color=09c&amp;sidebar_color=f2f2f2'; require('includes/header-inc.php'); ?> I know: <cfinclude template="includes/header-inc.cfm"> but how to i get the var to be passed to the include and then how do I use it on the subsequent included file? Also in my CSS (main.php) I have (at the top): <?php header('Content-type: text/css'); foreach($_GET as $css_property => $css_value) {define(strtoupper($css_property),$css_value);} ?> and im using those constants like this: #main-content a {color:#<?= LINK_COLOR ?>;} How can I get that to work also with CF? Never thought I'd be working with CF :)

  • MVC : Checkboxes generated using JavaScript not appearing in FormCollection on postback

    - by Andy Evans
    I took over another project (written by one contractor, modified by another and now it's not working) written using MVC/C# where a view that has a table (see below) is dynamically populated using JSON/Javascript - the first column of which is a checkbox. View (spark view engine) <table id='component_list' name='component_list' cellpadding='0' border='0' cellspacing='0'> <thead> <tr> <th>&nbsp;</th> <th>Component</th> <th>Component Type</th> <th>Evenflo Part #</th> <th>Supplier Part #</th> <th>Supplier</th> <th>Requirement</th> <th>Location</th> <th>Region</th> </tr> </thead> <tbody> </tbody> </table> When the page is rendered, I look at the source for the page and do not see the table data (I wouldn't expect to see this). However, when the form is posted back, controller, the FormCollection is empty. Supposedly this had been working before the last contractor got their hands on it - which is another post all together. My goal right now is having the checkboxes in the FormCollection. Any suggestions would be greatly appreciated. Thanks,

  • backbone.js removing template from DOM upon success

    I'm writing a simple message board app to learn backbone. It's going ok (a lot of the use of this isn't making sense) but am a little stuck in terms of how I would remove a form / html from the dom.

  • Cant' cast a class with multiple inheritance

    - by Jay S.
    I am trying to refactor some code while leaving existing functionality in tact. I'm having trouble casting a pointer to an object into a base interface and then getting the derived class out later. The program uses a factory object to create instances of these objects in certain cases. Here are some examples of the classes I'm working with. // This is the one I'm working with now that is causing all the trouble. // Some, but not all methods in NewAbstract and OldAbstract overlap, so I // used virtual inheritance. class MyObject : virtual public NewAbstract, virtual public OldAbstract { ... } // This is what it looked like before class MyObject : public OldAbstract { ... } // This is an example of most other classes that use the base interface class NormalObject : public ISerializable // The two abstract classes. They inherit from the same object. class NewAbstract : public ISerializable { ... } class OldAbstract : public ISerializable { ... } // A factory object used to create instances of ISerializable objects. template<class T> class Factory { public: ... virtual ISerializable* createObject() const { return static_cast<ISerializable*>(new T()); // current factory code } ... } This question has good information on what the different types of casting do, but it's not helping me figure out this situation. Using static_cast and regular casting give me error C2594: 'static_cast': ambiguous conversions from 'MyObject *' to 'ISerializable *'. Using dynamic_cast causes createObject() to return NULL. The NormalObject style classes and the old version of MyObject work with the existing static_cast in the factory. Is there a way to make this cast work? It seems like it should be possible.

  • vb.net inline IF with OR... not evaluating

    - by rockinthesixstring
    I'm working on a small problem where I'm trying to show/hide a panel based on two criteria A specific data field must not be blank The specific data filed must also not equal "Not Relocatable" Unfortunately this doesn't seem to be working for me (note that setting either one or the other criteria works just fine.) <asp:Panel runat="server" Visible='<%#If(Not String.IsNullOrEmpty(DataBinder.Eval(Container.DataItem, "_236")) Or Not DataBinder.Eval(Container.DataItem, "_236") = "Not Relocatable", True, False)%>'> <tr> <td> </td> <td class="align-right lightgreen"> Buyer would consider relocating a business, if it is: </td> <td> </td> <td colspan="3"> <%#DataBinder.Eval(Container.DataItem, "_236")%> </td> <td> </td> </tr> </asp:Panel> Can anyone lend a hand to rectify this problem for me?

  • Have any software engineers gotten math degrees later in their careers?

    - by vin
    I have a bachelors in computer science and worked the last 12 years as a software engineer. I'm bored with doing general development work, so I want to specialize. I'm thinking about getting a master's degree in math so I can build math models and write algorithms to implement them. I'm unsure what type of work I'd do (financial, gaming, graphics, science, research, etc) but I'm open minded. I would need to refresh my undergrad math skills (which are old and faded), but I loved algebra and calculus. I've been working with couple statisticians so I've been finding myself more interested in statistics. Since I'm a parent supporting a household, I would have to continue working while studying. Have any software engineers taken this route? (Specifically, going from BS in comp sci to MS in math.) If so, what advice do you have for coursework, financing, and getting a job that combines programming with advanced math? How abundant are these kinds of jobs? I'm not sure where one starts. Also, how do you hop from a BS to an MS in a different subject?

  • Trying to get django app to work with mod_wsgi on CentOS 5

  • How do I add two alternating UITableViews to an existing UINavigationController view?

    - by Ron Flax
    I'm new to iPhone development and I am writing an iPhone app that needs two different table views, which are selectable using a button bar or tab bar. These table views are both the same size, but only cover about two thirds of the screen from the bottom up. The top portion of the screen remains the same when either of these tables is displayed. I'd also like to animate (flip) these views when the user selects one or the other. The view that these two tables will be displayed on is the detail view of my app where the user has already selected an item from the primary screen's table. I'm using a UINavigationController to manage the primary and detail views and I have this working. I also have the first of these two detail tables working as part of my detail view, but I think it makes more sense to isolate the code for these two tables and not duplicate all of the code for the part of the detail view that doesn't change. I don't really care how these two table views are created (either in code or via IB). I've tried several things and I can't seem to figure it out. Any help or ideas (with sample code) would be greatly appreciated!

  • Load SQL query result data into cache in advance

    - by Marc
    I have the following situation: .net 3.5 WinForm client app accessing SQL Server 2008 Some queries returning relatively big amount of data are used quite often by a form Users are using local SQL Express and restarting their machines at least daily Other users are working remotely over slow network connections The problem is that after a restart, the first time users open this form the queries are extremely slow and take more or less 15s on a fast machine to execute. Afterwards the same queries take only 3s. Of course this comes from the fact that no data is cached and must be loaded from disk first. My question: Would it be possible to force the loading of the required data in advance into SQL Server cache? Note My first idea was to execute the queries in a background worker when the application starts, so that when the user starts the form the queries will already be cached and execute fast directly. I however don't want to load the result of the queries over to the client as some users are working remotely or have otherwise slow networks. So I thought just executing the queries from a stored procedure and putting the results into temporary tables so that nothing would be returned. Turned out that some of the result sets are using dynamic columns so I couldn't create the corresponding temp tables and thus this isn't a solution. Do you happen to have any other idea?

  • iPad width in viewport settings overflowing past device width

    - by user1327771
    I am at my wit's end here, and I beseech the fine folks here at stackoverflow for help. I am working on a design for a blog for a friend of mine, and I'm working in HTML5. I am trying to get the width of the page to span the width of an iPad. So, in my document head, I have the following: <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0"> Now, if you go to the index page, on an iPad, it looks just fine. The width of the page spans the width of the iPad in portrait mode, as I expect it to: http://www.alanreuterart.com/femmegamers/index.html It also looks fine on any individual blog posts as well. However, on the "about" and "join" pages, the width does not do this. It's actually overflowing past the length of the iPad to the right. View the following page on an iPad to see what I mean: http://www.alanreuterart.com/femmegamers/about.html I've tried everything. I cannot, for the life of me, figure out how to get it those two pages to correctly span the device width of the iPad. One important note, though: before anyone tells me to set my viewport width to 960, I cannot do that because the pages have media queries in them to convert to a mobile layout for the iPhone and other mobile phones. (I am not making a special unique layout for the iPad.) Can ANYONE help out here? Thanks in advance! —Me.
