  • Facebook Hacker Cup: Power Overwhelming

    - by marcog
    A lot of people at Facebook like to play Starcraft II™. Some of them have made a custom game using the Starcraft II™ map editor. In this game, you play as the noble Protoss defending your adopted homeworld of Shakuras from a massive Zerg army. You must do as much damage to the Zerg as possible before getting overwhelmed. You can only build two types of units, shield generators and warriors. Shield generators do no damage, but your army survives for one second per shield generator that you build. Warriors do one damage every second. Your army is instantly overrun after your shield generators expire. How many shield generators and how many warriors should you build to inflict the maximum amount of damage on the Zerg before your army is overrun? Because the Protoss value bravery, if there is more than one solution you should return the one that uses the most warriors. Constraints 1 = G (cost for one shield generator) = 100 1 = W (cost for one warrior) = 100 G + W = M (available funds) = 1000000000000 (1012)

  • C# .NET Controls for docked tool windows?

    - by Brett Powell
    I was using Qt with C++ to develop my GUI applications, but I have recently switched to try out C# .NET as it is much easier to do what I need to. I was wondering what controls I need to be using for a few things and if they exist for C# .NET or if I need to do something custom/special. If you look in that screenshot, I want to do something similar to how they have each tool window grouped into its own docking area with the option of closing it or breaking it out of the layout so it can be dragged. I am talking about the tool windows titled "Groups", "Resources", "Tools", etc. I also want to make these tool windows stay in the same place when the main window is resized. Qt has spring like widgets that will let you create a UI that keeps its shape when the window is resized. Does anything like this exist in C# .NET?

  • Sending bulk notification emails without blocking

    - by FreshCode
    For my client's custom-built CRM, I want users (technicians) to be notified of changes to marked cases via email. This warrants a simple subscription mapping table between users and cases and automated emails to be sent every time a change is made to a case from within the logging method. How do I send 10-100 emails to subscribed users without bogging down my logging method? My SMTP server is on a peer on my LAN, so sends should be quick, but ideally this should be handled by an external queuing process. I can have a cron job send any outstanding emails every 10 minutes, but for this specific client cases are quite time-sensitive and instant notification (as instant as email can be) would be great. How can I send bulk notification emails from within ASP.NET MVC without bogging down my logging method?

  • In Windows 7, clicking between file explorer windows does not generate window events. What's up?

    - by asmw
    I have a custom made global hook installed and am monitoring for window messages when file explorer windows are clicked on. The funny thing is that they don't generate any window messages! I click between two file explorer windows and nothing. No VM_CREATE, no VM_ACTIVATE. Nothing. Why is this? Spy++ crashes on my machine so I can't use it but my hook is pretty good and should pick everything up. For some reason these windows just don't function like normal windows in that they don't generate the standard window messages when they become active. It seems windows 7 does not see them as normal windows? what's going on?

  • Best anti boss tricks to hide your private page navigation from your desktop.

    - by systempuntoout
    This question is slightly related to programming and it's kinda lame, i know; but i saw many funny things in these years and i'm looking for new tricks from you. I'm talking about methods to fast-hide\camouflage not job related web pages on your desktop when boss arrives like a ghost\ninja behind your shoulders. I know how much can be frustrating, programming hard for ten hours and then been caught by your boss watching XKCD during a 2 minutes break. I think the most common anti boss trick is the evergreen CTRL+TAB, but you have to be fast and your left hand has to be near the keyboard. I saw pitch black brightness on Lcd (how can you pretend to program on that?) or custom sized browser to fit a little space just below the IDE. My favourite one at the moment is using fire gesture plugin with FF; with a micro gesture you can hide FF to your tray in a blink of an eye. Do you have any trick to share?

  • How to use Map element as text of a JComboBox

    - by llm
    I am populating a JComboBox (using addItem()) with all the elements of a collection. Each element in the collection is a HashMap (so its a ComboBox of Hashmaps..). My question is - Given that I need each item to be a HashMap how do I set the text to apear in the combobox on the GUI? It needs to be the value of a certain key in the map. Normally if I am populating a combobox with my own type, I would just overide the toString() method...but I am not sure how to acheive this since I am using a Java HashMap. Any ideas (if possible, without implementing my own HashMap)? Update: It seems like there isn't anyway to avoid having the object int the JComboBox overide toString() if I want custom functionality..I wish there was a way to (1) specify the objects to be loaded into the JComboBox and (2) specify how these objects are to appear in the GUI.

  • How can should I set up Flex 3 projects that reference common controls?

    - by Amy
    I'm not a flash developer, I'm having issues figuring out how I should set up these two projects that I have in Flex Builder. I've already created projA which has a .mxml that references several custom controls & skins from com.xxx.controls within projA I now have to build projB which also has a .mxml that will create a different .swf. I want to use some of the same controls from projA I currently build projA through the command line and nant and will need to do the same for projB. Should I create a new project to move all of the common controls into? How do I then use this library project in both the projects & compile via command? Thanks!

  • Compare TinyMCE and CKeditor for a Wiki

    - by Lakshman Prasad
    For a custom wiki django-wakawaka, i want to be able to add a WYSIWYG support. TinyMCE is obviously the most popular plugin, used even by Wordpress. But CK-editor seems more feature full. Those who have used either of these or both, which is better and why. Are there some better packages, that I am missing? Is there something that I am missing when I conclude CKeditor is better, by going through them (because it is not as widely used). I want to use it with django and jquery, with multiple instances of WYSIWYG widget per page. Does one offer advantage over the other.

  • How can a Delphi TPersistent object calculate its own deserialization time?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

  • resetting the image in an NSView

    - by Josan
    I think this is a very simple question, but I’m new to programming so I may be going about it in a wrong-headed way. I have a basic understanding of Objective-C writing terminal applications and am teaching myself how to use the Cocoa GUI. I understand how to use IBOutlet and IBAction to connect a simple button to a method that will repeatedly send random numbers to a textfield . I understand how to add a NSView file, connect it to a custom view in interface builder and draw a path through random points in the view when the application launches. (I’ve been putting this code inside the - (void)drawRect:(NSRect)dirtyRect method that is declared when the file is created). What I can’t seem to figure out is how to connect a button to an action that will then ‘refresh’ the view – in this case repopulate it with another set of random points connected with a path. Looking at the documentation, I think I should somehow be using – (void) setNeedsDisplay(BOOL)flag but nothing I have tried so far had worked. Please tell me, what am I missing here?

  • Repeated requests on our server?

    - by pitty.platsch
    I encountered something strange in the access log of our Apache server which I cannot explain. Requests for webpages that I or my colleagues do from the office's Windows network get repeated by another IP (that we don't know) a couple of seconds later. The user agent repeating our requests is Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2) Has anyone an idea? Update: I've got some more information now. The referrer of the replicate is set to the URL I requested before and it's not the exact same request as the protocol version is changed from 'HTTP/1.1' to 'HTTP/1.0'. The IP is not just one, it's just one of a subnet (80.40.134.*). It's just the first request to a resource that's get repeated, so it seems the "spy" is building up some kind of cache of visited places. The repeater is also picky. I tried randomly URLs with different HTTP status codes and different file patterns. 301s and 200s are redone, 404s not. Image extensions seem to be ignored. While doing my tests I discovered that this behavior seems to be common as I found other clients visiting just after the first requests: 66.249.73.184 - - [25/Oct/2012:10:51:33 +0100] "GET /foobar/ HTTP/1.1" 200 10952 "-" "Mediapartners-Google" 50.17.125.180 - - [25/Oct/2012:10:51:33 +0100] "GET /foobar/ HTTP/1.1" 200 41312 "-" "Mozilla/5.0 (compatible; proximic; +http://www.proximic.com/info/spider.php)" I wasn't aware about this practice, so I don't see it that much as a threat anymore. I still want to find out who this is, so any further help is appreciated. I'll try later if this also happens if I query some other server where I have access to the access logs and will update here then.

  • Captcha Alternative, how secure?

    - by aslum
    I do the web page for my local library, and I was thinking it might be kind of appealing to have a "custom" captcha based on book covers. So serve up one of several dozen book covers, and have the patron filling out the form type the book title to prove they're human. Assuming I stripped the title/author info from the image and filename, would that be enough? Would the fact that it was a unique system on a fairly small website be enough to make it effective? Just how tricky are the spam bots these days? Would having the image name be the ISBN # be too obvious?

  • LBA48 in Linux SCSI ATA Passthrough

    - by Ben Englert
    I am writing a custom disk monitoring/diagnostics app which, among other things, needs to do stuff to SATA disks behind a SAS PCI card under Linux. So far I am following this guide as well as the example code in sg_utils to pass ATA taskfiles through the SCSI layer. Seems to be working okay. However, in both cases, the CDB data structure (pointed to by the cmdp member of the sg_io argument to the ioctl) has only one unsigned char worth of space for the number of sectors. If you look at the ata_taskfile structure in linux\ata.h you'll see that it has an "nsect" and a "hob_nsect" field - high order bits for the sector count, to support LBA48. It turns out that in my application I need LBA48 support. So, anyone know how to set up an sg_io_hdr structure with an LBA48 sector count?

  • How can I detect 'any' ajax request being completed using jQuery?

    - by Brian Scott
    I have a page where I can insert some javascript / jquery to manipulate the output. I don't have any other control over the page markup etc. I need to add an extra element via jquery after each present on the page. The issue is that the elements are generated via an asynchronous call on the existing page which occurs after $(document).ready is complete. Essentially, I need a way of calling my jquery after the page has loaded and the subsequent ajax calls have completed. Is there a way to detect the completion of any ajax call on the page and then call my own custom function to insert the additional elements after the newly created s ?

    Hi everyone I have compiled an sqlite database that I would like to make public. I want to provide a very simple webpage that has a few form elements which are used to query the database.

  • Simple Emacs keybindings

    - by User1
    I have two operations that I do all the time in Emacs: Create a new buffer and paste the clipboard. [C-S-n] Close the current buffer. [C-S-w] Switch to the last viewed buffer [C-TAB] I feel like a keyboard acrobat when doing the first two operations. I think it would be worth trying some custom keybindings and macros. A few questions about this customization: How would I make a macro for #1? Are these good keybindings (i know this is a bit subjective, but they might be used by something popular that I don't use) Has anyone found a Ctrl-Tab macro that will act like Alt-Tab in Linux/Windows? Specifically, I want it have a stack of buffers according to the last viewed timestamp (most recent on top). I want to continue cycling through the stack until I let go of the ctrl key. When the ctrl key is released, I want the current buffer to get an updated position on the stack.

  • How to force a WebPart to display in all pages of a portal?

    - by Mehdi
    Hi, I'm working on a portal/CMS project and (unfortunately) build the foundation on WebParts platform. However I need to provide an option for admin to choose whether a webpart should be display in all pages or not. Finally I've found a nice article from Damon Armstrong that describes a way to store all personalization data of a group of pages into one record. Thus every changes the admin made for a webpart, affect whole pages. But it doesn't seems to be a solution for me. May be it would be solved by writing a custom personalization provider, but I don't now how. Any Ideas about the problem? Thanks

  • How do you create a Google Maps-esque drop down dialog?

    - by Daniel Lew
    In the Google Maps application, when you open the menu and click on "Directions", it pops up a dialog that is unique to Google Maps. It keeps the MapView in the background, but displays the search dialog from the top (or bottom, if you're on an old version of Android). I was curious if anyone knew how they achieved this effect. I'm willing to create a custom Dialog, but it seems that Dialogs are designed to pop into the middle of the screen (any other types of dialogs are denied permission as system dialogs). What trick is Google Maps using?

  • How to configure Hibernate database reverse engineering tool to map database table relation as a ent

    - by Piotr Kochanski
    Is it possible to configure Hibernate reverse engineering and code generation tool in such a way that one-to-many relation between tables is mapped to entities inheritance instead of enrites relation? I have Person table and Employee table, which are related with the foreign key (Person contains basic information, Employee the rest). In my Java code I would like this relation mapped to inheritance Employee extends Person. This can be done by hand, but maybe I missed some custom configuration parameter that I can use. I couldn't find any official documentation - docs link on RedHat Hibernate page (http://www.hibernate.org/5.html#A10) is broken...

  • Android Jar libraries

    - by Jeremy Edwards
    How do you setup a project that can result in a jar library file that can be used for android? I want to create a custom library across all projects. Few other questions: Does it need to be compiled against a specific version of android sdk? When an android package is compiled against a jar library does the classes necessary to work with the code get compiled with main code into the apk or does the entire jar get included? Any notable optimizations or pitfalls I need to know about with using a jar instead of integrating the code directly? Does the jar have to be signed like the apk needs to?

  • Choosing a Portal / CMS software for developing multi brand websites?

    - by hbagchi
    We are in the early stage of overhauling a multi-brand website built using a custom developed java mvc framework to enable web 2.0 features. Built-in features we are looking at are: i18n, sso, content search and indexing, personalization, mashup support, ajax support, rich media content storage and management support, friendly to search engine optimizations, bookmarkable URLs, support for social networking sites, support for page composition and decoration using templates. A combination of these features are supported by many portal and cms software. Any insights will be very helpful in using a portal/cms combination to address this requirements! This is a follow-up on this post focusing on the portal/cms angle

  • Using an image as a border

The issue that I am having is that the border skin does not appear the way that I had hoped it would. Here is a ss of the skin in place. Ideally I should have a transparent box with a 5 pixel border around it.
