• MCV/MVP Patterns and Applications that interface with Hardware (DAQ/PLC/etc)

  - by Ryan

  I've been reading a lot about the MCV and MVP patterns for use with UI and it seems like a really nice powerful way to handle user interfaces. I am - however - having a difficult time deciding how this could integrate into a system where data in the model is created from a Data Acquisition System or Serial/Ethernet devices. There is also the added step that 70% of application interaction is performed by a PLC instead of a live user. It seems that for apps that just read/write & manipulate information from a database this works great, but how does does hardware and automation fit into these patterns? Is it as simple as another controller (for lack of a better term) that interacts with hardware that manipulates data and writes to a model? Maybe I am over thinking this or thinking too simply, so any advice would be great. I'm not quite sure where I'm going with this, so if something doesn't make sense or I was too vague leave me a comment. Thanks!

• Can I safely store UInt32 to NSUInteger?

  - by mystify

  In the header, it is defined like: #if __LP64__ || (TARGET_OS_EMBEDDED && !TARGET_OS_IPHONE) || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64 typedef long NSInteger; typedef unsigned long NSUInteger; #else typedef int NSInteger; typedef unsigned int NSUInteger; #endif So does an UInt32 fit without problems into an NSUInteger (an unsigned int)? Where's the difference between UInt32 and unsigned int? And I assume that an unsigned long is bigger than an unsigned int?

• Facebook graph api - delete like

  - by Martin

  Hi there, I'm developing an app for Facebook in PHP, part of which lists the user's "likes". I would like to add a link next to each like so that the user can manage their likes by deleting them where they see fit. Facebook mentions this in their graph api docs: "You can delete a like by issuing a DELETE request to /POST_ID/likes (since likes don't have an ID)." But each like must have an id - how else would you delete it? Has anyone done this before, any help will be appreciated.

• Given a number of rectangles that can be rotated, find an enclosing rectangle of minimum area

  - by efficiencyIsBliss

  So, I'm trying to implement an algorithm that takes in a number of rectangles as input and tries to pack them into a rectangle of minimum area. The rectangles can all be rotated by 90 degrees. I realize that this is similar to the bin packing problem, but I am unable to find a good algorithm that accounts for the rotation. I found a paper that discusses this at length here and while I understand the article itself, I was hoping to find something simpler. Any suggestions? -Edit- I think I misstated the problem earlier. We are given a number of rectangles, such that each can be rotated by 90 degrees. We need to find a rectangle that fits all the given rectangles such that no two rectangles overlap, while minimizing the area of the enclosing rectangle. The problem I face here is that we are asked to find the minimum, as opposed to being given an enclosing rectangle and checking if the given rectangles fit or something of that sort.

• Operational Transformation library?

  - by gamers2000

  I'm looking for a library that would allow me to synchronize text in real-time between multiple users (ala Google Docs). I've stumbled upon Operational Transformation, which seems to fit my needs. Having said that, I understand the gist of OT, but not the math nor implementation of OT. Thus, I was wondering if there was a drag'n'drop Javascript library that would hook into a text area, generate the transforms, then allow me to apply those transformations onto another client? (I've gotten the Etherpad source, but I can't make head or tails out of it. If anyone could point out how to leverage on Etherpad's OT implementation, that'll be great too!)

• How to set a dialog themed activity width to screen width?

  - by Pentium10

  I am followin the method described here to create an EditText input activity. But the view doesn't fill the width of the screen. How can I tell to fit the screen width? <activity android:name="TextEntryActivity" android:label="My Activity" android:theme="@android:style/Theme.Dialog"/> - <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:orientation="vertical" android:gravity="right" android:layout_height="wrap_content"> <EditText android:text="@+id/txtValue" android:id="@+id/txtValue" android:layout_width="fill_parent" android:layout_height="wrap_content"></EditText> <Button android:text="Done" android:id="@+id/btnDone" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button> </LinearLayout>

• Can GraphViz be used for a graph editing GUI?

  - by user185420

  I am creating an application which will allow a developer to create a program flow-chart by selecting pre-defined functions from a ToolBox (which will show up as small graphical elements). In other words, developer will select one or more pre-defined functions (graphical elements) from ToolBox and drag-drop on the main work area. The application will then, based on the flow of functions selected, will auto-generate ready-to-compile-code. I looked a GraphViz, but am not sure whether it can be used to create a GUI IDE for editing graphical elements. I am looking for a functionality similart to Microsoft Visio, where users can add/remove/drag-drop/ various shapes to create a diagram. Does GraphViz fit in here? If yes, can you direct me to some examples showing how to do it? If GraphViz cannot be used, what are the other open source/free components available? I am intending to build the final application in .Net.

• Float over two elements

  - by eWolf

  My problem is rather complex to explain, so I'll show you an example: http://ewolf.bplaced.de/misc/float.htm I want to have a floated element (the blue box) to be be placed over two other elements (red and green) and I want the whole thing to be fixed-width and centered (done by the box with the black border) while the background of the red and green box should fill the whole width. I'm actually not quite sure if the way I've done it now is XHTML/CSS valid, but it works - at least in Firefox. In IE6, the green box expands to fit the whole blue box - how can I fix this in IE6 or find another solution to show it correctly in all browsers?

• Howto read system informations in C++ on windows and linux?

  - by f4

  I need to read system information like cpu/ram/disks usage in C++. Maybe swap, network and process too but that's less important. It has probably been done thousand of times before so I first tried to search for a library. Someone here suggested SIGAR, which seems to fit my needs but is GPL and it is for inclusion in a proprietary product. So it's not an option here. I feel like it's something not that easy to implement, as it'll need testing on several platforms. So a library would be welcome. If you don't know of any library, could you point me in the right direction for both platforms?

• Is there a standard .NET exception to throw when a class doesn't implement a required attribute?

  - by a typing monkey

  Suppose I want to throw a new exception when invoking a generic method with a type that doesn't have a required attribute. Is there a .NET exception that's appropriate for this situation, or, more likely, one that would be a suitable ancestor for a custom exception? For example: public static class ClassA { public static T DoSomething<T>(string p) { Type returnType = typeof(T); object[] typeAttributes = returnType.GetCustomAttributes(typeof(SerializableAttribute), true); if ((typeAttributes == null) || (typeAttributes.Length == 0)) { // Is there an exception type in the framework that I should use/inherit from here? throw new Exception("This class doesn't support blah blah blah"); // Maybe ArgumentException? That doesn't seem to fit right. } } } Thanks.

• iPhone + selecting a portion of UIImage using some rectangular frame and than cropping it

  - by pratik

  Hello, I have requirement of selecting a portion of UIImage displayed on iPhone screen (for e.g. selecting the face from the image of some human being) using some rectangular type of frame. It means a rectangular type of frame can be moved across the image to place it at portion that we want. After placing it, I need to resize the frame in order to have that portion completely fit in the frame. Finally, the UIImage should be cropped so that I have a UIImage only displaying the portion that I selected using the frame. Please help me. Regards, Pratik

• Are there Adaptive Replacement Cache patent-free alternatives?

  - by aleccolocco

  An open source high-performance project I'm working on needs to keep a cache of parsed/compiled files. A plain LRU or a plain LFU wouldn't fit. Plain LRU wouldn't work as there will be remote batch/spider processes hitting the service regularly. Plain LFU wouldn't work because content will age. ARC seems like the perfect solution but since IBM holds patents to it at least one open source project dropped it. Are there any (good enough) alternatives? EDIT: I'm not looking for exactly the same thing, just something that could handle those two situations. Perhaps some simple strategy with timestamps and sources. There have to be many programmers who faced this situation before. That's why the "good enough" bit.

• Question regarding CGRectIntersectsRect and rotated rectangular image

  - by user309030

  Hi guys, I've got a long rectangular image which is rotated at different kind of angles. However the frame of the rectangular image does not rotate along with the image and instead, the rotation causes the frame to to become larger to fit the rotated image. So when I used CGRectIntersectsRect, the collision detection is totally off because the other image colliding with the rectangular image will collide before it even reaches the visible area of the rect image. In case you don't really know what I'm talking about, have a look at the ascii drawing: normal rectangular image frame, O - pixels, |, – - frame |----------| |OOOOOOOOOO| |----------| after rotation |----------| |O | | O | | O | | O | | O | | O | | O | | O | | O | |----------| I've read through some of the collision articles but all of them are talking about collision with a normal straight rectangle and what I really want is collision with a slanted image, preferably pixel collision detection. TIA for any suggestions made.

• How can I use splne() with ggplot?

  - by David

  I would like to fit my data using spline(y~x) but all of the examples that I can find use a spline with smoothing, e.g. lm(y~ns(x), df=_). I want to use spline() specifically because I am using this to do the analysis represented by the plot that I am making. Is there a simple way to use spline() in ggplot? I have considered the hackish approach of fitting a line using geom_smooth(aes(x=(spline(y~x)$x, y=spline(y~x)$y)) but I would prefer not to have to resort to this. Thanks!

• jquery ui position fails with margin

  - by oliwel

  Hi, I am trying to use jQuery to position an inpage div (Context-Menu) relative to a clicked tablerow on a webpage. This works fine until I add an offset with either "left" or "margin-left" to the outer container. Using padding-left works.... The relevant code is: $('#supermenu').position({ my: "left top", at: "left top", of: $(event.target).closest('tr'), collision: "fit" }); The caller looks like: <tr onclick="getMenu(event)"><td>.... What happens: The left margin is added "twice" to the X Offset, so the Menu is not aligned to the left border of the table but somewhere right of it. The offset from the border is exactly the offset from the outer container. Anybody can shed some light? Oliver

• Automatic website screenshots for Web app?

  - by amfeng

  Is there a way to take automatic screenshots of a web page (by specifying its URL) in a web app using PHP or Ruby on Rails? Perhaps using a plugin or some external REST service. I've researched a lot, and nothing seems to fit except something like this (http://www.binarymoon.co.uk/2010/02/automated-take-screenshots-website-free/) but I doubt Wordpress would just let me spam their servers for something not Wordpress related. I'd like to use it for my own web application so I'm not sure of the legal implications..how hard is this to implement myself? What does it entail? Thanks!

• .NET 2d library for circuit diagrams

  - by Dinah

  I want to draw and manipulate logic flow (as opposed to analog) circuit diagrams and I'm trying not to reinvent the wheel. Problems like positioning, line drawing, line crossing and connecting, path finding, rubberband lines, and drag & drop are also identical in flow charts, UML diagrams, or class diagrams so I started by viewing related topics via Google and Stack Overflow. However, the following requirements seemed to keep me from finding anything that quite fit: assuming a chip has an image with input and output stubs, the connecting lines would connect to the chip only in the exact spots of the I/O stubs the color of connecting lines are able to be set as per a chip's output Is there an existing .NET 2d graphics library that would be suitable for drawing circuit diagrams?

• How do you deploy your SharePoint solutions?

  - by Lars Mæhlum

  I am now in the process of planning the deployment of a SharePoint solution into a production environment. I have read about some tools that promise an easy way to automate this process, but nothing that seems to fit my scenario. In the testing phase I have used SharePoint Designer to copy site content between the different development and testing servers, but this process is manual and it seems a bit unnecessary. The site is made up of SharePoint web part pages with custom web parts, and a lot of Reporting Services report definitions. So, is there any good advice out there in this vast land of geeks on how to most efficiently create and deploy a SharePoint site for a multiple deployment scenario? Edit Just to clarify. I need to deploy several "SharePoint Sites" into an existing site collection. Since SharePoint likes to have its sites in the SharePoint content database, just putting the files into IIS is not an option at this time.

• iPhone - Make loadView entries fill up parent view?

  - by Eli

  I have a loadView call that basically places one view at the top (like a header) and one at the bottom (like a footer). It's possible via a passed in parameter to not have a header or a footer, to hide them later, or to resize the view. I have all this working, but it's very susceptible to breaking because the views can go in various places of various sizes and all must be manually set to the correct size or they will not use up all the space. I want one in between the two of them that automatically resizes to fill whatever space is not taken by the others. loadView doesn't seem to be able to obtain the size of its parent's frame (or where it's being fit in, exactly), nor do I see an obvious way to just put the center view at a certain position and have its width and height automatically adapted. Any ideas? If I'm not explaining myself well enough and you know Java Swing, think BorderLayout with a BorderLayout.NORTH, BorderLayout.SOUTH, and BorderLayout.CENTER component.

• Has anybody used the WB B-tree library?

  - by Chris B

  I stumbled across the WB on-disk B-tree library: http://people.csail.mit.edu/jaffer/WB It seems like it could be useful for my purposes (swapping data to disk during very large statistical calculations that do not fit in memory), but I was wondering how stable it is. Reading the manual, it seems worringly 'researchy' - there are sections labelled [NOT IMPLEMENTED] etc. But maybe the manual is just out-of-date. So, is this library useable? Am I better off looking at Tokyo Cabinet, MemcacheDB, etc.? By the way I am working in Java.

• Need a good way to share iPhone source code on the Web.

  - by CJCraft.com

  Hi, I'm looking for a way to share some iPhone SDK source code I have with others. Goals: Share iPhone SDK source code, Objective C written in XCode. I have a good bit of source code I want to share. I'd like for it to be easy. I'd like for it to have syntax highlighting, by this I mean coloring and formatting Ideally it would allow me some room to make it "fit" into my site. I want it to look like basically another page on my site where the content is the code. It shouldn't be just a text file in other words. Here's an example where someone was able to do this for C#: http://www.opennetcf.com/library/sdf/ I guess what I want is the ability to create html documentation for all the classes, etc.

• Saving an IP adddress to DB

  - by Mark

  I want to save a user's IP address to my database just in case any legal issues come up and we need to track down who performed what action. Since I highly doubt I will ever actually need to use this data (well, maybe for counting unique hits or something) do you think I can just dump the REMOTE_ADDR into a field? If so, what should the length of that field be? 39 chars should fit an IPv6 address, no? I don't know if I'll ever get any of those, but just in case...

I know there are different applications/use-case scenarios which have different encoder used but i want to consdier all that and have a overall usage number(%) My guess is(highest to lowest % of content) - H.264(AVC) DivX MPEG2 VP6 Where do H.263, MPEG4, VC-1, RV, Theora, etc. fit in here. How may this look like in future? PS:I would like this to be community wiki to have get wider range of inputs, if someone with privileges can do it for me please. thank you. -AD

• Picture position in a desktop background slideshow

  - by user334017

  I'm using windows 7 and I have a slideshow for my desktop background. I have pictures that are all of varying sizes, some are smaller then my screen's resolution, some are the same, and some are much larger. To look good, smaller wallpapers need to have their picture position set to 'center' (where the picture is centered on the screen and the background color fills up the edges). And the larger backgrounds need to be set to 'fit' (where the picture is scaled down so the entire image is shown on the screen). I can't seem to figure out a way to have the picture position intelligently change in my background slideshow so that the wallpapers always look good. Any insight?

• Validation of dependent properties in a "live edit" WPF app

  - by Ryan Cromwell

  I'm working on an app which supports live editing. That is you update properties in one area and their impact is seen in another with hitting "apply". Happens to be a charting app. One such edit "group" allows specifying a range. A triple range in fact: High, Target and Low. Our validation is such that High must be greater than target, target must be greater than Low (rocket science). Our dilemma is that the visual experience is a bit jarring when someone wants to go from say 30,20,10 to 15,10,5. I'm curious if anyone has implemented a mechanism for this scenario that might fit well in our situation such that we don't "yell" at the user as they change the range values.
