  • Recognizing when to use the mod operator

    - by Will
    I have a quick question about the mod operator. I know what it does; it calculates the remainder of a division. My question is, how can I identify a situation where I would need to use the mod operator? I know I can use the mod operator to see whether a number is even or odd and prime or composite, but that's about it. I don't often think in terms of remainders. I'm sure the mod operator is useful and I would like to learn to take advantage of it. I just have problems identifying where the mod operator is applicable. In various programming situations, it is difficult for me to see a problem and realize "hey! the remainder of division would work here!" Any tips or strategies? Thanks

  • SCSI Windows Setup on Dell Precision 670 Workstation...please help.

    - by sweetcoder
    Error Windows Setup: "setup did not find any hard disk drives installed in your computer" This is not exactly a programming question but I thought you guys might be able to help. I just received a Dell Precision 670 workstation. Windows is not recognizing the hard drive and I have experienced this before with other computers. I usually would just go in the bios and set the configuration to compatibility mode. I have no idea how to do this on this machine. There is this Adaptec SCSI HostRaid BIOS v4.30.4S5 screen on startup. It says to press CTRL A for SCSI select utility. It shows a Maxtor ATLAS10K5_73WLS for the drive. I was wondering if anyone out there knew how to configure this thing so that windows setup will recognize the hard drive? Any advice is very much appreciated and if you have to know further information please let me know. Raid was turned off in the BIOS for this device. TY

  • Trying to understand Java Classloading

    - by Jens
    Hello, I'm currently getting to know Java and OSGi, so I've read a few books. In one particular book the class loading is described. You can download it (free and legal) from the authors page (Neil Bartlett): OSGi Book On page 9 and 10 are this pictures: It seems like there is the possibility that our class "Foo" won't use the class "Bar" of foobar.jar, but instead class "Bar" from naughty.jar. Because of the flat and global structure of the Java classpath this could be, but as far as I know you would define a package from where you want to import a certain class: import foobar.Bar This should prevent loading the wrong class, shouldn't it? Of course assuming that the package is called "foobar".

  • how to add "Existing solution folder recursively" to my VS2005 solution

    - by user36753
    I tried drag and drop from the explorer, but no luck with following error: "Folders cannot be dropped or pasted as solution items. Choose an individual document instead." I know we can create each folders/subfolders manually and add each file, but any quick way to do this on visual studio 2005? Updated: Thank you for the reply, but I do not want the folders to be added under any project, It should appear as a separate node inside my solution, like any other project. In this case the show all files does not work, since the solution itself does not have any folder, it is only if we select any project it works. I know we can create each folders/subfolders manually and add each file, but any quick way, because there are few hundreds of files.

  • Ruby Programming Techniques: simple yet not so simple object manipulation

    - by Shyam
    Hi, I want to create an object, let's say a Pie. class Pie def initialize(name, flavor) @name = name @flavor = flavor end end But a Pie can be divided in 8 pieces, a half or just a whole Pie. For the sake of argument, I would like to know how I could give each Pie object a price per 1/8, 1/4 or per whole. I could do this by doing: class Pie def initialize(name, flavor, price_all, price_half, price_piece) @name = name @flavor = flavor @price_all = price_all @price_half = price_half @price_piece = price_piece end end But now, if I would create fifteen Pie objects, and I would take out randomly some pieces somewhere by using a method such as getPieceOfPie(pie_name) How would I be able to generate the value of all the available pies that are whole and the remaining pieces? Eventually using a method such as: myCurrentInventoryHas(pie_name) # output: 2 whole strawberry pies and 7 pieces. I know, I am a Ruby nuby. Thank you for your answers, comments and help!

  • Installing Daemons

    - by Shahmir Javaid
    Dear Stackoverflowers, A simple link would be nice for me to understand how to install my C++ program as a deamon in UNIX, now i know some will say this should be on SERVERFAULT but as far as i understand it i need the init.d shell script to actually create the start and stop for the daemons. But if you guys can show me a simple shell script for the daemon and the file directories every thing required is associated with, that would be great. I was going to do this http://www.linux.com/archive/feed/46892 but if you read the comments every one is moaning x( . P.S. ive already done the required code for C++ to run as a daemon i just need to know how to actually install it as a daemon. At the moment im using crontab which is just not a good idea for the future of my problem. Thanks in advance

  • EnvDTE: ArgumentException when accessing the ActiveConfiguration

    - by Smith
    Hello, I'm writing an addin for Visual Studio 2008. At some point in my code, I'm attempting to access the current active configuration for a project: var configName = _Project.ConfigurationManager.ActiveConfiguration.ConfigurationName; Sometimes, in some very obscure cases, the getter for ActiveConfiguration throws an ArgumentException. Nothing in the documentation says anything about this (but given the very poor quality of the documentation, it was to be expected), and the exception's message is not helping at all. Also, ConfigurationManager is an interface, and I don't know what's the real implementation behind it, so I can't simply disassemble it in Reflector to know the cause. Any help would be greatly appreciated.

  • Detect the FTS3 extension in SQLite3

    - by pts
    What is the SQLite query to detect if the FTS3 extension module is installed? Or is it possible to get a list of installed extensions with an SQLite3 query? It has to work with pysqlite2. I know that I can get the list of tables using SELECT * FROM sqlite_master, I'd like to get something similar for the list of extensions. I also know that CREATE VIRTUAL TABLE v USING FTS3 (t TEXT) succeeds iff FTS3 is installed, but I'd like to get a query without side effects (not even creating a temporary table).

  • Does weak typing offer any advantages?

    - by sub
    Don't confuse this with static vs. dynamic typing! You all know JavaScripts/PHPs infamous type systems: PHP example: echo "123abc"+2; // 125 - the reason for this is explained // in the PHP docs but still: This hurts echo "4"+1; // 5 - Oh please echo "ABC"*5; // 0 - WTF // That's too much, seriously now. // This here might be actually a use for weak typing, but no - // it has to output garbage. JavaScript example: // A good old JavaScript, maybe you'll do better? alert("4"+1); // 51 - Oh come on. alert("abc"*3); // NaN - What the... // Have your creators ever heard of the word "consistence"? Python example: # Python's type system is actually a mix # It spits errors on senseless things like the first example below AND # allows intelligent actions like the second example. >>> print("abc"+1) Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> print("abc"+1) TypeError: Can't convert 'int' object to str implicitly >>> print("abc"*5) abcabcabcabcabc Ruby example: puts 4+"1" // Type error - as supposed puts "abc"*4 // abcabcabcabc - makes sense After these examples it should be clear that PHP/JavaScript probably have the most inconsistent type systems out there. This is a fact and really not subjective. Now when having a closer look at the type systems of Ruby and Python it seems like they are having a much more intelligent and consistent type system. I think these examples weren't really necessary as we all know that PHP/JavaScript have a weak and Python/Ruby have a strong type system. I just wanted to mention why I'm asking this. Now I have two questions: When looking at those examples, what are the advantages of PHPs and JavaScripts type systems? I can only find downsides: They are inconsistent and I think we know that this is not good Types conversions are hardly controllable Bugs are more likely to happen and much harder to spot Do you prefer one of the both systems? Why? Personally I have worked with PHP, JavaScript and Python so far and must say that Pythons type system has really only advantages over PHPs and JavaScripts. Does anybody here not think so? Why then?

  • Windows Forms in Visual Studio Express

    - by noname
    Good day, can I ask one question about Windows Forms? As far as I know Windows Forms is Win32 wrapper like MFC, created for use with .NET. But, what I dont know is, can you use windows forms and compile directly to native code? Becouse in Visual Studio Express, there is windows forms available only for CLR. And, there is no GUI tool for use with win32 project. I expected there will be one, since its called Visual, like Visual Basic has. Thanks.

  • Vim Register Use in Ex Mode

    - by Peck
    Potentially 2 questions in one. I would like to know how to reference a register in Ex mode. For instance, I'm editing a file and I want to save the file with a timestamp (or just datestamp really) appended to it. I know I can set register to the value of a shell commands output using: :let @a = system("date +\"%Y-%m-%d\"") Is there any to dereference this register and insert its value into an Ex command? Something like: :w testfile.<value of "a register> Copying to the system clipboard and pasting would be nice, but doing it in a more generic/programitic way for building on other commands in the future would be nice.

  • Simplex noise vs Perlin noise

    - by raRaRa
    I would like to know why Perlin noise is still so popular today after Simplex came out. Simplex noise was made by Ken Perlin himself and it was suppose to take over his old algorithm which was slow for higher dimensions and with better quality (no visible artifacts). Simplex noise came out in 2001 and over those 10 years I've only seen people talk of Perlin noise when it comes to generating heightmaps for terrains, creating procedural textures, et cetera. Could anyone help me out, is there some downside of Simplex noise? I heard rumors that Perlin noise is faster when it comes to 1D and 2D noise, but I don't know if it's true or not. Thanks!

  • has_many :through on self?

    - by Glex
    I have a User model. A user can be either a dj, a club, or a clubber (this is controlled by the User#account_type attribute). A club can have many djs, and a dj can have many users: enumerated_attribute :account_type, %w(^clubber dj club), :nil => false do label :clubber => "Clubber" label :dj => "DJ" label :club => "Club" end has_many :dj_club_relationships, :class_name => "User", :dependent => :destroy has_many :dj_user_relationships, :dependent => :destroy has_many :djs, :through => :dj_club_relationships, :class_name => "User" has_many :users, :through => :dj_user_relationships However, this doesn't work as well as expected, since Rails doesn't know, for example, that it needs to destroy all dj_club_relationships with club_id when the user being destroyed is a club, and with dj_id when the user is a dj. How can I help rails know about it?

  • Project in Eclipse that builds a jar used by another project in Eclipse

    - by Paul Tomblin
    I have several projects open in Eclipse. One of them is the main app, and others build jars used by that main app. How do I make it so that when I hit F3 on a method call in the main app that it takes me to the source in the other project instead of taking me to the class file in the Libraries list? I got it so that it shows me the source, but I can't actually edit it like it could if I go to the other project, and similarly when I step through in the debugger it doesn't go into the editable code. I don't know if it's relevant, but we're using Maven to handle the dependencies. I know this should be simple, but I haven't found the option.

  • mysql.sock file missing after installing MySQL on Snow Leopard

    - by Hristo
    This is a recent problem... MySQL was working and a couple of days ago I must have done something. I deleted MySQL and tried reinstalling using the .dmg file. The mysql.sock file never gets created and I get the following error messages: Hristo$ mysql Enter password: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) I also tried stopping Apache and installing but Apache gave me an error... I don't know if this is good or bad: Hristo$ sudo apachectl stop launchctl: Error unloading: org.apache.httpd I tried the MacPorts installation as well but the socket file still didn't get created. I don't really know what to do and I don't want to reinstall Snow Leopard and start from scratch :/ I also tried installing the 32-bit version and same deal. No luck. Any ideas? Thanks, Hristo

  • Silverlight 4 - elevated permission *inside* the browser

    - by Doug
    I know Silverlight 4 can handle elevated permissions outside the browser. Is there a way to accomplish this inside the browser? I need to make a folder/file upload manager that gives a better user experience than the standard , and I'd like to implement it in Silverlight. I know Java has an option to gain elevated permissions, but you have to attach a signed certificate to your app. Does Silverlight 4 have a similar option - to gain elevated permissions by attaching a signed certificate (after warning the user, of course)? -Doug

  • How can I overwrite a System.Drawing.Bitmap onto an existing GDI bitmap?

    - by MusiGenesis
    If I have a .Net Bitmap, I can create from it a GDI bitmap by calling the Bitmap's GetHbitmap() method. Bitmap bmp = new Bitmap(100, 100); IntPtr gdiBmp = bmp.GetHbitmap(); This works fine, but every time you call GetHbitmap, Windows has to allocate new memory for the object that gdiBmp references. What I'd like to do - if possible - is write a function (I know PInvoke will be necessary here) that also generates a GDI bitmap copy of a Bitmap, but that uses an existing object instead of allocating a new one. So it would look something like this (if it were an extension method of Bitmap): //void OverwriteHbitmap(IntPtr gdi) Bitmap bmp1 = new Bitmap(100, 100); IntPtr gdi1 = bmp1.GetHbitmap(); Bitmap bmp2 = new Bitmap(100, 100); bmp2.OverwriteHbitmap(gdi1); How can I do this? I assume I'll need to know the structure of a GDI bitmap, and probably I can use LockBits and BitmapData for this, but I'm not sure exactly how.

  • Locating binding errors

    - by softengine
    I'm dealing with a large WPF application that is outputting a large number of binding errors. A typical error looks like this: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.ItemsControl', AncestorLevel='1''. BindingExpression:Path=HorizontalContentAlignment; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'HorizontalContentAlignment' (type 'HorizontalAlignment') Problem is I don't know where in the app this is coming from. Searching the entire solution for AncestorType={x:Type ItemsControl} doesn't necessary help since I still don't know which result is the culprit. I've tried setting PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.All; but the extra information doesn't help locate the problematic bindings. File names and line numbers is really what I need. Is there anyway to get this information?
