• AVR Analog Comparator + Internal Pullup?

  - by vicatcu

  I have what I hope is a simple question pertaining to the Atmel AVR microcontrollers. So I want to use the ATTiny85's Analog Comparator to determine if a signal is above or below a threshold. This signal is normally "floating" and grounded when "active" (i.e. it's an active low - open collector signal). If I enable the pullup on the input pin (which is also the comparator input) by doing: DDRB = 0x00; // DDRB.1 = 0 = input PORTB = 0xFF; // PORTB.1 = 1 = internal pullup enabled If i use the analog comparator and select PORTB.1 as AIN1 will the internal pullup be applied to my input signal? I'm hoping someone has personal experience to verify this behavior. Hope this question isn't too 'hardware-oriented' for stack-overflow. Thanks!

• Qt not displaying PNG images on Linux

  - by ereOn

  Hi, I have a software written using Qt which is meant to work on both Windows and Linux. I use PNG images as icons for my QActions, embedded in a resource. I have the following tree directory: / resources/ icons.qrc image.png Here is the content of icons.qrc: <RCC> <qresource prefix="/resources" lang="fr"> <file alias="image.png">image.png</file> </qresource> </RCC> I declare my QIcon like that: QIcon(":/resources/image.png") Under Windows, it works well but on Linux (I only tried on Ubuntu 10.4 so far), the images aren't displayed. Is there anything special I have to do for this to work ? Is this a configuration problem ? Thank you.

• Modify EXE to stop launching firefox

  - by Random Joe

  I'm using a wireless modem program from my ISP. This program automatically disconnect when it detects the line is idle. It does so in 2-5 minutes of idle time. Whenever I reconnect, It will automatically fire up my default browser to the ISP portal. I DID NOT pay them to shove their web portal in my face 50 times a day. The ISP provides no options for disabling this behavior. Can someone please show me how to hex edit the EXE program to stop it from annoying the hell out of me?

• Multiple complete HTTP requests stuck in TCP CLOSE_WAIT state

  - by Sean Owen

  I have a Java and Tomcat-based server application which initiates many outbound HTTP requests to other web sites. We use Jakarta's HTTP Core/Client libraries, very latest versions. The server locks up at some point since all its worker threads are stuck trying to close completed HTTP connections. Using 'lsof' reveals a bunch of sockets stuck in TCP CLOSE_WAIT state. This doesn't happen for all, or even most connections. In fact, I saw it before and resolved it by making sure to set the Connection: Close response header. So that makes me think it may be bad behavior of remote servers. It may have come up again since I moved the app to a totally new service provider -- different OS, network situation. But, I am still at a loss as to what I could do, if anything, to work around this. Some poking around on the internet didn't turn up anything I'm not already doing. Just thought I'd ask if anyone has seen and solved this?

• Hudson CI project doesn't run NetBeans JUnit tests of dependent projects

  - by Liron Yahdav

  I have a set of NetBeans java projects with dependencies between them. I added the project at the top of the dependency tree to Hudson for continuous integration. Everything works fine, except that the unit tests of dependent projects don't get run by Hudson. This is because the ant scripts that NetBeans creates has dependent projects setup to run the "jar" target and not a target that also runs the unit tests. I could add ant build steps for each dependent project in Hudson to run the unit tests, but I was hoping there's a simpler solution.

• Casting to generic type in Java doesn't raise ClassCastException?

  - by Kip

  I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

• Which GUI control is suitable for this purpose?

  - by pecker

  Hello, I'm using winforms of .NET & C#. I'm developing a medical software. I need to implement "Patient History". When doctor enters the PatientID. All the previous appointment dates will be displayed in a side panel. These entries will dynamically fetched from the database. Interface will be more or less similar to Histroy in web browser. Except that I'm not going to use tree control and categorize entries into 'today' 'yesterday' 'older than 7 days' 'last week' etc.. What controls do I need to use. I'm not clear about this. If you have any better idea. Please mention.

• Does C99 guarantee that arrays are contiguous ?

  - by kriss

  Following an hot comment thread in another question, I came to debate of what is and what is not defined in C99 standard about C arrays. Basically when I define a 2D array like int a[5][5], does the standard C99 garantee or not that it will be a contiguous block of ints, can I cast it to (int *)a and be sure I will have a valid 1D array of 25 ints. As I understand the standard the above property is implicit in the sizeof definition and in pointer arithmetic, but others seems to disagree and says casting to (int*) the above structure give an undefined behavior (even if they agree that all existing implementations actually allocate contiguous values). More specifically, if we think an implementation that would instrument arrays to check array boundaries for all dimensions and return some kind of error when accessing 1D array, or does not give correct access to elements above 1st row. Could such implementation be standard compilant ? And in this case what parts of the C99 standard are relevant.

• What is the best method for implementing mouse wheel activity in Delphi VCL forms?

  - by Brian Frost

  As a long time user of Delphi 7, I've rolled my own mouse wheel handling in a few controls but lately I've noticed that some recent applications only need the mouse cursor to be placed over a control (e.g a list box or tree view) for the mouse wheel activity to cause that control to scroll. This feels nice (as opposed to having to click focus a control before it responds to the wheel. Now I've moved to Delphi 2010 I'm wondering what is the 'correct' behavior? And what can I use in Delphi that avoids me having to bodge this with my own solutions now? Thanks.

• Java webapp: where/how to automatically set each picture's width/height

  - by NoozNooz42

  For several reasons, a lot of "webmaster guides" (like Google and Yahoo!'s webmaster guides/guidelines) repeats several times that it is better to always put the width and height attribute of the img tag. One of the most obvious reason is that the elements in the page won't seem to be "jumping around" to a new location after every picture is loaded (always setting the correct width/height sure gets rid of this behavior). And there are other reasons to follow these guidelines / best practices. So: if we consider that these are indeed good practices if there are a lot of pictures and they are changing often if pictures aren't changing between two .war re-deploy (that is: there's no user-contributed picture) if we don't want to manually edit all these width/height attributes How do we automatically/programmatically serve HTML pages where every img tag have their width/height attribute correctly set as the best practice recommend?

• Gtk# TreeView set a single cell to have a different renderer?

  - by Buttink

  OK this is probably insane, but I want to be able to have a check box at the very top of every row in my tree view. This box will "disable" or "enable" the ability to use the column. Oh I think it should be mentioned that I'm using a ListStore and am using C#, mono, GTK#. However, ill take anything and try to figure it out. Ill even accept a way to make two views where the columns line up .... So, possible? or just insane?

• Hard link not works under MacOS in GUI mode

  - by AntonAL

  Hi, i faced a little strange behavior, while using hard links. From terminal, i create a text file 1.txt and a hard link "to this file" nano 1.txt mkdir dir ln 1.txt ./dir/ I check the resulting hard link and see, that it's contents is the same, as of "original" file. less ./dir/1.txt I change the initial file ... nano 1.txt ... and see, that changes was reflected in hard-link less ./dir/1.txt I change content of hard-link (more correct, of course - file, being referenced with hard-link) ... nano ./dir/1.txt ... and see, that changes are reflected in initial file less 1.txt Until now, all going well... Now, I close terminal and start playing with created files (1.txt and ./dir/1.txt) from Finder. When i change on this two files with TextEdit, changes are not reflected in another file. Just like the hard link was teared off... Whats going on here ?

• Insert Comment Reply Form Into Page Using Jquery

  I have been making a threaded comment system as a way to learn php and javascript/jquery properly. Ive done bits and bobs in the past but ive made a new years resolution to learn it properly. Im having trouble inserting a reply form into the comment tree below the comment being replied to.

This code wasn't working for me: $(document).ready(function(){ $(function() { $('a#reply').click(function() { $(this).append("the html blah"); }); }); }); Anyone see where im going wrong?

I need to get it in another class.

• Get all window handles for a process

  - by Jeremy

  Using Microsoft Spy++, I can see that the following windows that belong to a process: Process XYZ window handles, displayed in tree form just like Spy++ gives me: A B C D E F G H I J K I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object? To enumerate I'm using the win32 call: [System.Runtime.InteropServices.DllImport(strUSER32DLL)] public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

• Adding Java packages to GWT

  - by Organiccat

  I've tried searching but couldn't come up with a defined way on how to add your own packages to a GWT project. My tree structure looks like this: -com.mycompany -public MyApplication.html MyApplication.gwt.xml -com.mycompany.client MyApp.java -com.mycompany.gui TableLayout.java The answer I've seen out there says to add the packages relative to the root directory of the gwt.xml file, like so: <module> <inherits name="com.google.gwt.user.User" /> <entry-point class="com.mycompany.client.MyApp" /> <source path="client" /> <source path="gui" /> </module> It then complains: Unable to find type 'com.technicon.client.MyApp' Hint: Previous compiler errors may have made this type unavailable Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly Can anyone tell me what I'm doing wrong and how to fix this?

• Ruby and Forking

  - by Cory

  Quick question about Ruby forking - I ran across a bit of forking code in Resque earlier that was sexy as hell but tripped me up for a few. I'm hoping for someone to give me a little more detail about what's going on here. Specifically - it would appear that forking spawns a child (expected) and kicks it straight into the 'else' side of my condition (less expected. Is that expected behavior? A Ruby idiom? My IRB hack here: def fork return true if @cant_fork begin if Kernel.respond_to?(:fork) Kernel.fork else raise NotImplementedError end rescue NotImplementedError @cant_fork = true nil end end def do_something puts "Starting do_something" if foo = fork puts "we are forking from #{Process.pid}" Process.wait else puts "no need to fork, let's get to work: #{Process.pid} under #{Process.ppid}" puts "doing it" end end do_something

• Why does TabStop stop working??

  - by Jerry

  I have a project that uses a series of auto-generated user control instances. The user-control itself exists, but I populate a panel with a series of these user controls, one for each item in my collection. Each user control displays a ton of information, but only ONE text field is editable. All of the other fields have TabStop set to false, and are marked as ReadOnly. The tab order of each user control is set at the time it is created so that the tab-key goes from one field to the next (or ... it's supposed to). When I have TWO fields on my user control whose TabStop is set to true, everything works great. But if I only have ONE field whose TabStop is true, the tab key stops working, and I have to physically CLICK on the next user control for it to gain focus. What's up? Has anyone else seen this behavior? Am I doing something stupid as usual?

• wx Menu disappears from frame when shown as a popup

  - by Adam Fraser

  I'm trying to create a wx.Menu that will be shared between a popup (called on right-click), and a sub menu accessible from the frame menubar. The following code demonstrates the problem. If you open the "MENUsubmenu" from the menubar the item "asdf" is visible. If you right click on the frame content area, "asdf" will be visible from there as well... however, returning to the menubar, you will find that "MENUsubmenu" is vacant. Why is this happening and how can I fix it? import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): ''' R-click callback ''' f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) frame_menu = wx.Menu() f.MenuBar.Append(frame_menu, 'MENU') frame_menu.AppendMenu(-1,'submenu', m) f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop() Interestingly, appending the menu to MenuBar works, but is not the behavior I want: import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) f.MenuBar.Append(m, 'MENU') f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop()

• Fixing warning from git

  - by japancheese

  I've been doing a workflow of making a git repository on a remote central repository, cloning that repo on my local dev machine, doing some work, and then pushing the changes back to the same repo on the remote server. However, and I believe this was after an update I did to git recently, after pushing up a change, I'm getting the following warning: Counting objects: 2724, done. Delta compression using up to 2 threads. Compressing objects: 100% (2666/2666), done. Writing objects: 100% (2723/2723), 5.90 MiB | 313 KiB/s, done. Total 2723 (delta 219), reused 0 (delta 0) warning: updating the currently checked out branch; this may cause confusion, as the index and working tree do not reflect changes that are now in HEAD. Can someone explain to me exactly what this warning means, and what I'm doing wrong in my workflow to not receive this warning?

• How does refer(r)er work technically?

  - by NoozNooz42

  I don't understand: how are webserver and trackers like Google Analytics able to track referrals? Is it part of HTTP? Is it some (un)specified behavior of the browsers? Apparently every time you click on a link on a web page, the original web page is passed along the request. What is the exact mechanism behind that? Is it specified by some spec? I've read a few docs and I've played with my own Tomcat server and my own Google Analytics account, but I don't understand how the "magic" happens. Bonus (totally related) question: if, on my own website (served by Tomcat), I put a link to another site, does the other site see my website as the "referrer" without me doing anything special in Tomcat?
