  • How are vector patterns used in syntax-rules?

    - by Jay
    Hi, I have been writing Common Lisp macros, so Scheme's R5Rs macros are a bit unnatural to me. I think I got the idea, except that I don't understand how one would use vector patterns in syntax-rules: (define-syntax mac (syntax-rules () ((mac #(a b c d)) (let () (display a) (newline) (display d) (newline))))) (expand '(mac #(1 2 3 4))) ;; Chicken's expand-full extension shows macroexpansion => (let746 () (display747 1) (newline748) (display747 4) (newline748)) I don't see how I'd use a macro that requires its arguments to be written as a vector: (mac #(1 2 3 4)) => 1 4 Is there some kind of technique that uses those patterns? Thank you!

  • cross platform keyboard/mouse input recommendation

    - by Jay
    Does anyone have any suggestions for a good cross platform input library? I'd like to get: * at least keyboard and mouse input * on at least the big three operating systems * Small/fast * C or C++ * permissive licensing gpl2/mit/free/etc. So far I've seen: * OIS (used in Ogre) http://sourceforge.net/projects/wgois/ * SDL (used everywhere it seems, might be a clue) http://www.libsdl.org/index.php * Allegro http://www.talula.demon.co.uk/allegro/readme.html Has any one used any of these, or know of something else that might be good? Thanks

  • Why exactly is eval evil?

    - by Jay
    I know that Lisp and Scheme programmers usually say that eval should be avoided unless strictly necessary. I´ve seen the same recommendation for several programming languages, but I´ve not yet seen a list of clear arguments against the use of eval. Where can I find an account of the potential problems of using eval? For example, I know the problems of GOTO in procedural programming (makes programs unreadable and hard to maintain, makes security problems hard to find, etc), but I´ve never seen the arguments against eval. Interestingly, the same arguments against GOTO should be valid against continuations, but I see that Shemers, for example, won´t say that continuations are "evil" -- you should just be careful when using them. They´re much more likely to frown upon code using eval than upon code using continuations (as far as I can see -- I could be wrong).

  • Setting MinimumSize Attribute for a Control in a TFS WorkItem

    - by Jay Yother
    Tools used: Visual Studio 2008 SP1 Team Explorer Team Foundation Server Power Tools October 2008 Release. Using the Process Editor in Visual Studio, I am attempting to set the MinimumSize attribute for a control in a WorkItem template to make the default size of the input area larger. I am setting the attribute according to this website: http://msmvps.com/blogs/vstsblog/archive/2007/07/07/undocumented-attributes-for-controlling-the-work-item-form-layout.aspx No matter what I set this attribute to it has no affect. I have tried setting the attribute with and without surrounding (). I've tried different capitalization of the attribute but no luck. I have verified that the MinimumSize attribute is being correctly set in the associated xml file. The control (HtmlFieldControl) is currently setup as the second child on a Tab Page. (The first control is also an HtmlFieldControl.) I've tried adding a group to the Tab Page such that the hierarchy is TabPage-Group-Column-Control with no success. I've also tried setting the attribute for the first control with no luck. Any idea what I am doing wrong?

  • Ubuntu server 13 hangs on boot

    - by Slava Fomin II
    I formatted my WD30EFRX 3TB SATA HDD as GPT with the following layout: 200 MB FAT32 (BOOTABLE) 50GB EXT4 (Mount point: /) 4 GB SWAP SPACE ~2.9 TB EXT4 (with no mount point) Then i created a Flash USB using Rufus 1.3.3 and the following ISO-image: ubuntu-13.04-server-amd64.iso. I used following configuration to create the USB: GPT partition scheme for UEFI computer FAT32 (16KB) I successfully booted from this USB on my Intel D510MO motherboard in UEFI mode (there were a black and white boot loader menu instead of a colorful GUI) and installed the OS. During the boot loader installation i saw it was grub-efi-amd64 as it must be. After installation i removed the flash drive and tried to boot the system, but just after a BIOS POST it hangs (there is a white blinking cursor at the left top corner of the black screen) and nothing happens. UEFI Mode is enabled in the BIOS configuration and i've updated the BIOS to the latest firmware. What went wrong, how i can confirm that system was installed properly? How can i boot the OS?

  • JMonkey Engine (JME) load Blender scene with textures?

    - by leigero
    I am having the hardest time trying to accomplish the simplest task. I have created a floor and 4 walls (not that complicated) in Blender. I added a basic material and cloud texture so they have something to look at other than gray. When I import them into JMonkey they show up as solid white objects with no shading or depth. White silhouettes. I thought this may be a lighting issue, but I have ambient light added to the scene. I can remove that light or adjust its intensity and it has no affect on the scene. I exported all Blender files into OgreXML format, then converted them to .j3o format in JMonkey. I renamed the textures to match their corresponding mesh and this didn't do anything. Does anybody know how to create a flat object and put it into JMonkey with a texture? This sounds simple and there is absolutely no information on this. This should be step 1!

  • How can I do a clean Mod_Rewrite that hides the variable numbers passed in the query string but just

    - by Jay Bee
    Hi, I have been developing web applications for a while now. My applications have been fairing poorly in search engine results because of the dynamic links that my websites generate. I admire the way some developers do their mod_rewrite to produce something like: http://www.mycompany.com/accommodation/europe/ to run a substitute of "index.php?category_id=2&country=23" How can I achieve that in my urls? Warm regards, JB

  • PHP regex - find and replace

    - by jay
    Hi, I am trying to do this regex match and replace but not able to do it. Example <SPAN class="one">first content here</SPAN> <SPAN class="two">second content here </SPAN> <SPAN class="three">one; two; three; and more.</span> <SPAN class="four">more content here.</span> I want to find each set of the span tags and replace with something like this Find <SPAN class="one">first content here</SPAN> Change to <one>first content here</one> same way the the rest of the span tags. class="one", class="two" and so on are the only key identifier which I use in the regex match expression. So if I find a span tag with these class then I want to do the replace. My main issue is that I am not able to find the occurrence of first closing tag so what it does is it finds from the start to end which is of no use. So far I have been trying to do this using notepad++ but just found that it has its limitations so any php help would be appreciated. regards

  • Problem accessing updated variables within OnTouch

    - by Jay Smith
    I have an OnTouch and a setOnTouchListener that updates varibles which contain screen coord info. The problem is it doesnt seem to ever update them. On line 78, RGB.setText(test); it never changes from 0.0. If i were to move that line and the line above it into the onTouch it updates. any idea what is wrong? Thank you. package com.evankimia.huskybus; import com.test.huskybus.R; import android.app.Activity; import android.os.Bundle; import android.view.MotionEvent; import android.view.View; import android.view.View.OnTouchListener; import android.widget.TextView; public class HuskyBus extends Activity { TextView RGB; private CampusMap mCampusMap; private float startX = 0; //track x from one ACTION_MOVE to the next private float startY = 0; //track y from one ACTION_MOVE to the next float scrollByX = 0; //x amount to scroll by float scrollByY = 0; //y amount to scroll by /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); RGB = (TextView) findViewById(R.id.coordBox); mCampusMap = (CampusMap) findViewById(R.id.map); mCampusMap.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { // TODO Auto-generated method stub switch (event.getAction()) { case MotionEvent.ACTION_DOWN: // Remember our initial down event location. startX = event.getRawX(); startY = event.getRawY(); break; case MotionEvent.ACTION_MOVE: float x = event.getRawX(); float y = event.getRawY(); // Calculate move update. This will happen many times // during the course of a single movement gesture. scrollByX = x - startX; //move update x increment scrollByY = y - startY; //move update y increment startX = x; //reset initial values to latest startY = y; mCampusMap.invalidate(); break; }//end switch return false; } ; }); //end onDraw? String test = "" + scrollByX; RGB.setText(test); } }

  • Stop objects from wrapping in Android

    - by jay
    How do I prevent a TextView, or any visual object, from wrapping to the screen and instead being chopped off the sides? Is there some XML attribute or code to do this or is it impossible to have anything overflow from the screen? For example, you have this: But you really want this: Any ideas?

  • Running a GWT application (including Applets) inside an IFRAME from an ASP.NET 3.5 app?

    - by Jay Stevens
    We are looking at integrating a full-blown GWT (Google Web Toolkit 2.0) application with an existing ASP.NET 3.5 application. My first gut reaction is that this is a horrible frankenstein idea. However, the customer has insisted that we use this application developed by a third-party. I have almost NO CONTROL over the development of the GWT app. My first thought is to actually attempt to embed this in an iFrame. Because GWT is running under Tomcat/Jakarta, it is hosted on a different server from the .NET app so the iFrame src will be to a URL on the other machine. I need to utilize our own ASP.NET authorization scheme to restrict access to the embedded GWT application. The GWT app also uses embedded java applets, which don't seem to be working right now inside the iframe. The GWT app makes calls to a backend server (using GWT-RPC?). Any major problems with this approach that anyone can see? Will GWT work on an iframe while hosted on a different machine? NOTE: SIMPLY ADDING A DIV WITH THE SAME NAME DOES NOT WORK FOR THIS!

  • jquery hover issue

    - by jay
    hi, i have mouseover issues sometimes when i move my mouse fast over links it loops for quite a while, is there a way to only loop if mouse is stil over and stop if the mouse is not. $('ul.display li').hover(function() { $('ul.display li').find('#details').hide(); // hides all deatils div before showing $('#light').delay('800').fadeIn("fast"); // shows div that fades out all other content. if($.cookie("switch_thumb") =="thumb_view" || $.cookie("switch_thumb") =="null"){//checks for cookie set for display type $(this).find('#details').delay('900').animate({width:'toggle'}); // grow width }else{ $(this).find('#details').delay('900').animate({height:'toggle'}); // grow height } }, function() { $('#light').fadeOut("fast"); // dim the light to show all content $('ul.display li').find('#details').hide(); //hide all details return false; // supposed to stop looping. });

  • glColor3f Setting colour

    - by Aaron
    This draws a white vertical line from 640 to 768 at x512: glDisable(GL_TEXTURE_2D); glBegin(GL_LINES); glColor3f((double)R/255,(double)G/255,(double)B/255); glVertex3f(SX, -SPosY, 0); // origin of the line glVertex3f(SX, -EPosY, 0); // ending point of the line glEnd(); glEnable(GL_TEXTURE_2D); This works, but after having a problem where it wouldn't draw it white (Or to any colour passed) I discovered that disabling GL_TEXTURE_2D Before drawing the line, and the re-enabling it afterwards for other things, fixed it. I want to know, is this a normal step a programmer might take? Or is it highly inefficient? I don't want to be causing any slow downs due to a mistake =) Thanks

  • How to make images hosted on Amazon S3 less public but not completely private?

    - by Jay Godse
    I fired up a sample application that uses Amazon S3 for image hosting. I managed to coax it into working. The application is hosted at github.com. The application lets you create users with a profile photo. When you upload the photo, the web application stores it on Amazon S3 instead of your local file system. (Very important if you host at heroku.com) However, when I did a "view source" in the browser of the page I noticed that the URL of the picture was an Amazon S3 URL in the S3 bucket that I assigned to the app. I cut & pasted the URL and was able to view the picture in the same browser, and in in another browser in which I had no open sessions to my web app or to Amazon S3. Is there any way that I could restrict access to that URL (and image) so that it is accessible only to browsers that are logged into my applications? Most of the information I found about Amazon ACLs only talk about access for only the owner or to groups of users authenticated with Amazon or AmazonS3, or to everybody anonymously.

  • WPF binding behaviour different when bound property is declared as interface vs class type?

    - by Jay
    This started with weird behaviour that I thought was tied to my implementation of ToString(), and I asked this question: http://stackoverflow.com/questions/2916068/why-wont-wpf-databindings-show-text-when-tostring-has-a-collaborating-object It turns out to have nothing to do with collaborators and is reproducible. When I bind Label.Content to a property of the DataContext that is declared as an interface type, ToString() is called on the runtime object and the label displays the result. When I bind TextBlock.Text to the same property, ToString() is never called and nothing is displayed. But, if I change the declared property to a concrete implementation of the interface, it works as expected. Is this somehow by design? If so, any idea why? To reproduce: Create a new WPF Application (.NET 3.5 SP1) Add the following classes: public interface IFoo { string foo_part1 { get; set; } string foo_part2 { get; set; } } public class Foo : IFoo { public string foo_part1 { get; set; } public string foo_part2 { get; set; } public override string ToString() { return foo_part1 + " - " + foo_part2; } } public class Bar { public IFoo foo { get { return new Foo {foo_part1 = "first", foo_part2 = "second"}; } } } Set the XAML of Window1 to: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <StackPanel> <Label Content="{Binding foo, Mode=Default}"/> <TextBlock Text="{Binding foo, Mode=Default}"/> </StackPanel> </Window> in Window1.xaml.cs: public partial class Window1 : Window { public Window1() { InitializeComponent(); DataContext = new Bar(); } } When you run this application, you'll see the text only once (at the top, in the label). If you change the type of foo property on Bar class to Foo (instead of IFoo) and run the application again, you'll see the text in both controls.

  • C++: ifstream::getline problem

    - by Jay
    I am reading a file like this: char string[256]; std::ifstream file( "file.txt" ); // open the level file. if ( ! file ) // check if the file loaded fine. { // error } while ( file.getline( string, 256, ' ' ) ) { // handle input } Just for testing purposes, my file is just one line, with a space at the end: 12345 My code first reads the 12345 successfully. But then instead of the loop ending, it reads another string, which seems to be a return/newline. I have saved my file both in gedit and in nano. And I have also outputted it with the Linux cat command, and there is no return on the end. So the file should be fine. Why is my code reading a return/newline? Thanks.

  • MySQL multidimensional arrays...

    - by jay
    What is the best way to store data that is dynamic in nature using MySQL? Let's say I have a table in which one item is "dynamic". For some entries I need to store one value, but for others it could be one hundred values. For example let's say I have the following simple table: CREATE TABLE manager ( name char(50), worker_1_name(50), worker_2_name(50), ... worker_N_name(50) ); Clearly, this is not an ideal way to set up a database. Because I have to accommodate the largest group that a manager could potentially have, I am wasting a lot of space in the database. What I would prefer is to have a table that I can use as a member of another table (like I would do in C++ through inheritance) that can be used by the "manager" table to handle the variable number of employees. It might look something like this. CREATE TABLE manager ( name char(50), underlings WORKERS ); CREATE TABLE WORKERS ( name char(50), ); I would like to be able to add a variable number of workers to each manager. Is this possible or am I constrained to enumerating all the possible number of employees even though I will use the full complement only rarely?

  • Why is there no way to resize SRFI-4 vectors in Scheme?

    - by Jay
    I see that SRFI 4 does not mention resizing of vectors. I'm using f64vectors (for which I need fast access), and I'd like to be able to resize them quickly (similar to what realloc does in C), and not necessarily copy the whole vector. Since I didn't find any references to a "resize-f64vector" procedure, I'd like to know why it doesn't exist (and if making a new vector and copying over is my only option).

  • Pointer Arithmetic & Signed / Unsigned Conversions!

    - by Jay
    Incase of pointer arithmetic, are the integers automatically converted to their signed variants? If yes, why? Suppose I do pointer + uiVal where pointer is a pointer to int and uiVal is initialized to -1, then I find that the address in pointers get decremented by 4. Why is the unsigned value of -1 not considered here?
