• What is the point of CSS collapsing margins?

  - by Tom

  The CSS2 box model tells us that adjoining margins collapse. I find it quite annoying, being the source of many design bugs. I hope that by understanding the purpose of collapsing margins, I will understand when to use them and how to avoid them when they are not needed. What is the purpose of this feature?

• How Can I Make Apache Stop Serving ALL Unknown File Types (like .php~)?

  - by user223304

  I am coming from IIS and moving to Apache and recently found out that Apache by default serves up files of an unknown file extension as PURE TEXT. This can be an issue if a user uses certain programs that back up .php files as .php~. Then the .php~ file becomes completely readable by simply navigating to it in a browser. To make matters worse these .php~ files are often considered 'hidden' in the linux environment from the user so some may not even know they exist. Bots have been created around this fact that scour the internet looking for popular file name backups and extracting potentially secure info from them. I already know how to stop serving up .php~ files or any specific file extensions. I also know not to use any editors that would save backup files like this. My question is, how can I stop this default Apache behavior of serving up ANY non-MIME file type at all? I just don't like the this behavior and would like to stop it. I don't want it serving up .aspx~, .html~, .bob, .carl, no extension or anything else that is not a real MIME type. I know that I can probably go and use a directive to first Deny access to all file types. Then add the ones I want to serve out one by one. But I'm wondering if there's an easier/quicker way. Thanks for any help.

• How can one extract rdf:about or rdf:ID properties from triples using SPARQL?

  - by lennyks

  It seemed a trivial matter at the beginning but so far I have not managed to get the unique identifier for a given resource using SPARQL. What I mean is given, e.g., rdf:Description rdf:about="http://..." and then some properties identifying this resource, what I want to do is to first find this very resource and then retrieve all the triples given some URI. I have tried naïve approaches by writing statements in a WHERE clause such as: ?x rdf:about ?y and ?x rdfs:about ?y I hope I am being precise.

• css sprite button is jumping around

  - by Richard

  Hello everyone, Does anyone know what is causing the sprite rollover to jump around It is I think more likely a photoshop question, but I am not completely sure. I hope to get an answer here anyway, since I think most webdesigners/programmers problably worked with photoshop also. This is what I want the rollover to do example 1 and this is my testpage (see the play button) I made the sprite with spriteme.com thanks, Richard

• Use Java Annotation not to run a method

  - by Michael Mao

  Hi all: I've got a method in my class only for testing purpose : private void printOut(String msg, Object value) { System.out.println(msg + value); } It is a wrapper method for System.out.println(); So I hope, with the use of Annotation, I can choose not to run this method during productive environment while still keep those diagnostic output ready if I am to switch back to debugging environment. Which Annotation shall I put on top of the method name?

• How to debug a kernel created using ubuntu-vm-builder?

  - by user265592

  Aim: Trying to perform a code walkthrough of what functions are getting called for sending and receiving packets over the network. I am building a kernel and using gdb for debugging/ tracing purposes. I have build a vm using the following command : time sudo ubuntu-vm-builder qemu precise --arch 'amd64' --mem '1024' --rootsize '4096' --swapsize '1024' --kernel-flavour 'generic' --hostname 'ubuntu' --components 'main' --name 'Bob' --user 'ubuntu' --pass 'ubuntu' --bridge 'br0' --libvirt 'qemu:///system' And I can run the VM successfully in qemu using the following command: qemu-system-x86_64 -smp 1 -drive file=tmpGgEOzK.qcow2 "$@" -net nic -net user -serial stdio -redir tcp:2222::22 Now, I want to debug the kernel using gdb. For this I need an executable with debug symbols(vmlinux), which apparently I don't have, as the vm-builder never asked for any such options and simply created a .qcow2 file. Question 1: Am I taking the correct approach to solve the problem and is there an easier way to do it? Question 2: Is there a way to debug this kernel using GDB? P.S: I don't have hardware support for KVM. Please correct me if I am wrong. Thanks.

• Find location using only distance and bearing?

  - by pinnacler

  Triangulation works by checking your angle to three KNOWN targets. "I know the that's the Lighthouse of Alexandria, it's located here (X,Y) on a map, and it's to my right at 90 degrees." Repeat 2 more times for different targets and angles. Trilateration works by checking your distance from three KNOWN targets. "I know the that's the Lighthouse of Alexandria, it's located here (X,Y) on a map, and I'm 100 meters away from that." Repeat 2 more times for different targets and ranges. But both of those methods rely on knowing WHAT you're looking at. Say you're in a forest and you can't differentiate between trees, but you know where key trees are. These trees have been hand picked as "landmarks." You have a robot moving through that forest slowly. Do you know of any ways to determine location based solely off of angle and range, exploiting geometry between landmarks? Note, you will see other trees as well, so you won't know which trees are key trees. Ignore the fact that a target may be occluded. Our pre-algorithm takes care of that. 1) If this exists, what's it called? I can't find anything. 2) What do you think the odds are of having two identical location 'hits?' I imagine it's fairly rare. 3) If there are two identical location 'hits,' how can I determine my exact location after I move the robot next. (I assume the chances of having 2 occurrences of EXACT angles in a row, after I reposition the robot, would be statistically impossible, barring a forest growing in rows like corn). Would I just calculate the position again and hope for the best? Or would I somehow incorporate my previous position estimate into my next guess? If this exists, I'd like to read about it, and if not, develop it as a side project. I just don't have time to reinvent the wheel right now, nor have the time to implement this from scratch. So if it doesn't exist, I'll have to figure out another way to localize the robot since that's not the aim of this research, if it does, lets hope it's semi-easy.

• Explicit disable MySQL query cache in some parts of program

  - by jack

  In a Django project, some cronjob programs are mainly used for administrative or analysis purposes, e.g. generating site usage stats, rotating user activities log, etc. We probably do not hope MySQL to cache queries in those programs to save memory usage and improve query cache efficiency. Is it possible to turn off MySQL query cache explicitly in those programs while keep it enabled for other parts including all views.py?

• How to measure a canvas that has auto height and with

  - by Wymmeroo

  Hi Folks, I'm a beginner in silverlight so i hope i can get an answer that brings me some more light in the measure process of silverlight. I found an interessting flap out control from silverlight slide control and now I try to use it in my project. So that the slide out is working proper, I have to place the user control on a canvas. The user control then uses for itself the height of its content. I just wanna change that behavior so that the height is set to the available space from the parent canvas. You see the uxBorder where the height is set. How can I measure the actual height and set it to the border? I tried it with Height={Binding ElementName=notificationCanvas, Path=ActualHeight} but this dependency property has no callback, so the actualHeight is never set. What I want to achieve is a usercontrol like the tweetboard per example on Jesse Liberty's blog Sorry for my English writing, I hope you understand my question. <Canvas x:Name="notificationCanvas" Background="Red"> <SlideEffectEx:SimpleSlideControl GripWidth="20" GripTitle="Task" GripHeight="100"> <Border x:Name="uxBorder" BorderThickness="2" CornerRadius="5" BorderBrush="DarkGray" Background="DarkGray" Padding="5" Width="300" Height="700" > <StackPanel> <TextBlock Text="Tasks"></TextBlock> <Button x:Name="btn1" Margin="5" Content="{Binding ElementName=MainBorder, Path=Height}"></Button> <Button x:Name="btn2" Margin="5" Content="Second Button"></Button> <Button x:Name="btn3" Margin="5" Content="Third Button"></Button> <Button x:Name="btn1_Copy" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy1" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy2" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy3" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy4" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy5" Margin="5" Content="First Button"/> <Button x:Name="btn1_Copy6" Margin="5" Content="First Button"/> </StackPanel> </Border> </SlideEffectEx:SimpleSlideControl>

• overriding big popup on directions Google Maps

  - by Glycerine

  I've happily implemented v2 of Google maps to my site without a hitch, I also successfully perform a drive directions using GDirections.load(). What I need to do is stop the popup of the mini map when you select a particular step in the routing directions. So when the user clicks on say "step 3", instead of the default popup showing a mini map, I'd like to add a custom icon to that position. Hope it makes sense Thanks in advance guys.

• What does "Computing additional info" mean?

  Eclipse Helios periodically starts running a job which displays "Computing additional info". During this time, Eclipse is very sluggish, bordering on unusable. What does this job do? Can I shut it off? I just hope that someone in the JDT team comes to sense and gets rid of it, make it go faster, or at the very least change it to something meaningful.
