  • MATLAB: comparing all elements in three arrays

    - by sasha
    I have three 1-d arrays where elements are some values and I want to compare every element in one array to all elements in other two. For example: a=[2,4,6,8,12] b=[1,3,5,9,10] c=[3,5,8,11,15] I want to know if there are same values in different arrays (in this case there are 3,5,8)

  • Dependency Injection: I don't get where to start!

    - by Andy
    I have several articles about Dependency Injection, and I can see the benefits, especially when it comes to unit testing. The units can me loosely coupled, and mocking of dependencies can be made. The trouble is - I just don't get where to start. Consider this snippet below of (much edited for the purpose of this post) code that I have. I am instantiating a Plc object from the main form, and passing in a communications mode via the Connect method. In it's present form it becomes hard to test, because I can't isolate the Plc from the CommsChannel to unit test it. (Can I?) The class depends on using a CommsChannel object, but I am only passing in a mode that is used to create this channel within the Plc itself. To use dependancy injection, I should really pass in an already created CommsChannel (via an 'ICommsChannel' interface perhaps) to the Connect method, or maybe via the Plc constructor. Is that right? But then that would mean creating the CommsChannel in my main form first, and this doesn't seem right either, because it feels like everything will come back to the base layer of the main form, where everything begins. Somehow it feels like I am missing a crucial piece of the puzzle. Where do you start? You have to create an instance of something somewhere, but I'm struggling to understand where that should be. public class Plc() { public bool Connect(CommsMode commsMode) { bool success = false; // Create new comms channel. this._commsChannel = this.GetCommsChannel(commsMode); // Attempt connection success = this._commsChannel.Connect(); return this._connected; } private CommsChannel GetCommsChannel(CommsMode mode) { CommsChannel channel; switch (mode) { case CommsMode.RS232: channel = new SerialCommsChannel( SerialCommsSettings.Default.ComPort, SerialCommsSettings.Default.BaudRate, SerialCommsSettings.Default.DataBits, SerialCommsSettings.Default.Parity, SerialCommsSettings.Default.StopBits); break; case CommsMode.Tcp: channel = new TcpCommsChannel( TCPCommsSettings.Default.IP_Address, TCPCommsSettings.Default.Port); break; default: // Throw unknown comms channel exception. } return channel; } }

Can I do this in vi?

  • Installing Ruby 1.9.1 on Ubuntu?

    - by Björn
    I wonder about installing the latest version of Ruby on Ubuntu 9.04. Now I can run through the ./configure and make stuff fine, but what I wonder about: how to avoid conflicts with the packaging system? For example if some other package I install depends on Ruby, wouldn't the package manager install the (outdated) Ruby package and in the worst case overwrite my files? So I think I need some way to tell Ubuntu that Ruby is in fact already installed?

  • Scala: Can't catch exception thrown inside a closure

    - by Dmitriy
    Disclaimer: absolute novice in Scala :( I have the following defined: def tryAndReport(body: Unit) : Unit = { try { body } catch { case e: MySpecificException => doSomethingUseful } } I call it like this: tryAndReport{ someCodeThatThrowsMySpecificException() } While the call to someCodeThatThrowsMySpecificException happens just fine, the exception is not being caught in tryAndReport. Why? Thank you!

  • Opengl Coordinate System

    - by praveen
    Say I am using an Identity Matrix for my modelViewTransformation Matrix on an Open GL ES2.0 program. The Co-ordinate system in this case is the canonical opengl co-ordinate system which extends from (-1,-1,-1) to (1,,1,1). My question is, is this coordinate system right-handed or left-handed? A broader question: Is there a document with OpenGL which can list all the mathematical conventions followed by the API?

  • Converting string to email-attachment on android

    - by sandis
    So I have som data that I have converted to a string. While I have found how to attach something from the SD-card to a mail, I cant figure out how to directly convert my string to a mail-attachment without involving the SD-card. In case it holds significance, I have read some data from a database, converted it to csv-format, and now wants to attach it as a csv-file. Cheers,

  • SEO difference between dash and hypen

    - by FFish
    I understand with dashes once can search for keywords in different order. What if my keyword has a space in it like real estate or New York Should I use underscores in this case? If I do a Google search for New_York Google hints me: Did you mean: New York There is clearly a difference. Even capitals seems to make a difference, looking at the search results..

  • Creating secure .exe files in C#

    - by George
    Hi, I have heard some mutterings about C# being quite easy to "crack" and/or reverse engineer. Is this the case and if so, how can I go about preventing this, if possible ? Or at least making it more difficult ? Thanks, George.

  • SQL Server Express 2008 using (local) in connection string

    - by Jeff
    Is it possible to connect to a SQL Server Express 2008 database in ASP.NET with a server name of (local) like "server=(local);integrated security=SSPI;database=DBNAME"? I'm working with another developer on a project and it's getting annoying having to have 2 different version of web.config because he is using SQL Server 2008 and (local) works, but I can't seem to get it to work with SQL Server 2008 Express locally. The database is located on the same computer as the .NET code in case that matters. Thanks.

  • Subroutine to apply Daylight Bias to display time in local DST?

    - by vfclists
    UK is currently 1 hour ahead of UTC due to Daylight Savings Time. When I check the Daylight Bias value from GetTimeZoneInformation it is currently -60. Does that mean that translating UTC to DST means DST = UTC + -1 * DaylightBias, ie negate and add? I thought in this case for instance adding Daylight Bias to UTC is the correct operation, hence requiring DaylightBias to be 60 rather than -60.

  • Fastest way to represent a collection of bits in PHP?

    - by Piskvor
    What is a good way to represent a collection of bits? I have a set of various on/off toggles (thousands of them) and need to store and retrieve their state. The naïve implementation would be an array of booleans, but I'm wondering if there's a better way (better in terms of access speed and/or memory requirements). I've found this BitArray implementation, but it's limited to 32 bits, which is not enough for this case.

  • What versions/flavors of WinZip can be opened by the gnu.java.util.zip.dll v.6.0.140.8?

    - by dreynold
    Evaluating a third party data processing tool, I have bumped into a case where some WinZip files cause an exception: Caused by: gnu.java.util.zip.ZipException: Unknown compression method 98 at gnu.java.util.zip.ZipFile.getInputStream(ZipFile.java:470) I have seen this with files created with WinZip 11.2 and newer. What's the latest version of WinZip (or compatible compression method) that the zip.dll can handle? I've been hunting for some reference on this, but other than unversioned source code, I have had little luck so far.
