  • Generic Dictionary - Getting Conversion Error

    - by pm_2
    The following code is giving me an error: // GetDirectoryList() returns Dictionary<string, DirectoryInfo> Dictionary<string, DirectoryInfo> myDirectoryList = GetDirectoryList(); // The following line gives a compile error foreach (Dictionary<string, DirectoryInfo> eachItem in myDirectoryList) The error it gives is as follows: Cannot convert type 'System.Collections.Generic.KeyValuePair<string,System.IO.DirectoryInfo>' to 'System.Collections.Generic.Dictionary<string,System.IO.DirectoryInfo>’ My question is: why is it trying to perform this conversion? Can I not use a foreach loop on this type of object?

  • Please help me get my content div to get an auto height from absolutely positioned element

    - by Justin Hollender
    I need some help with a CSS layout. It is set up like this: +--------------------+ | | | header | |-| |--------------| | |nav| content | | | | | | | | | | | | | | footer | +--------------------+ So, the nav is supposed to be floating above all the main page content. That's why I have it set to be absolutely positioned. The issue is that the nav items are dynamic, without a set height. Right now, the nav expands past the content. How can I fix it so that the content will have an auto height based off the nav? Thanks in advance.

  • Automatic conversion between methods and functions in Scala

    - by fikovnik
    I would like to understand the rules when can Scala automatically convert methods into functions. For example, if I have following two methods: def d1(a: Int, b: Int) {} def r[A, B](delegate: (A, B) ? Unit) {} I can do this: r(d1) But, when overloading r it will no longer work: def r[A, B, C](delegate: (A, B, C) ? Unit) {} r(d1) // no longer compiles and I have to explicitly convert method into partially applied function: r(d1 _) Is there any way to accomplish following with the explicit conversion? def r[A, B](delegate: (A, B) ? Unit) {} def r[A, B, C](delegate: (A, B, C) ? Unit) {} def d1(a: Int, b: Int) {} def d2(a: Int, b: Int, c: Int) {} r(d1) // only compiles with r(d1 _) r(d2) // only compiles with r(d2 _) There is somewhat similar question, but it is not fully explained.

  • Floating toolbar on bottom, centered, 80% of current screen width

    - by Tom
    I'm trying to implement a Facebook like toolbar on the bottom of the screen for a website I'm currently working on. Currently, I have it 100% of the width of the screen but I'd like to have it look almost exactly like Facebook's toolbar, centered, bottom justified on top, around 80% of the current screen's width. Here is the current CSS for the toolbar I have that is 100% of the screen's width. Thanks in advance. CSS: <style type="text/css"> #toolbar { background:url('/_assets/img/toolbar.gif') repeat-x; height:25px; position:fixed; bottom:0px; width:100%; left:0px; border-left:1px solid #000000; border-right:1px solid #000000; z-index:100; font-size:0.8em; } </style>

  • Automating the choice between JPEG and PNG with a script

    - by MHC
    Choosing the right format to save your images in is crucial for preserving image quality and reducing artifacts. Different formats follow different compression methods and come with their own set of advantages and disadvantages. JPG, for instance is suited for real life photographs that are rich in color gradients. The lossless PNG, on the other hand, is far superior when it comes to schematic figures: Picking the right format can be a chore when working with a large number of files. That's why I would love to find a way to automate it. A little bit of background on my particular use case: I am working on a number of handouts for a series of lectures at my unversity. The handouts are rich in figures, which I have to extract from PDF-formatted slides. Extracting these images gives me lossless PNGs, which are needlessly large at times. Converting these particular files to JPEG can reduce their size to up to less than 20% of their original file size, while maintaining the same quality. This is important as working with hundreds of large images in word processors is pretty crash-prone. Batch converting all extracted PNGs to JPEGs is not an option I am willing to follow, as many if not most images are better suited to be formatted as PNGs. Converting these would result in insignificant size reductions and sometimes even increases in filesize - that's at least what my test runs showed. What we can take from this is that file size after compression can serve as an indicator on what format is suited best for a particular image. It's not a particularly accurate predictor, but works well enough. So why not use it in form of a script: I included inotifywait because I would prefer for the script be executed automatically as soon as I drag an extracted image into a folder. This is a simpler version of the script that I've been using for the last couple of weeks: #!/bin/bash inotifywait -m --format "%w%f" --exclude '.jpg' -r -e create -e moved_to --fromfile '/home/MHC/.scripts/Workflow/Conversion/include_inotifywait' | while read file; do mogrify -format jpg -quality 92 "$file" done The advanced version of the script would have to be able to handle spaces in file names and directory names preserve the original file names flatten PNG images if an alpha value is set compare the file size between the temporary converted image and its original determine if the difference is greater than a given precentage act accordingly The actual conversion could be done with imagemagick tools: convert -quality 92 -flatten -background white file.png file.jpg Unfortunately, my bash skills aren't even close to advanced enough to convert the scheme above into an actual script, but I am sure many of you can. My reputation points on here are pretty low, but I will gladly award the most helpful answer with the highest bounty I can set. References: http://www.formortals.com/introducing-cnb-imageguide/, http://www.turnkeylinux.org/blog/png-vs-jpg Edit: Also see my comments below for some more information on why I think this script would be the best solution to the problem I am facing.

  • convert mp4 to flv. Adobe Medio Encoder Failing.

    - by Derek Adair
    Hi, I am trying to encode a .mp4 to a .flv I've tried using the Adobe Media Encoder but the video is lost in the conversion process, leaving me a black screen and some audio. I have yet to find something that can do this successfully for free. I found ffmpeg, which looks promising... but I can't figure out how to get it to work. Any direction would be greatly appreciated. -Thanks.

  • How to convert tar file from gnu format to pax format

    - by nosid
    On the one hand I have a lot of tar files created with gnu format, and on the other hand I have a tool that only supports pax (aka posix) format. I am looking for an easy way to convert the existing tar files to pax format - without extracting them to the file system and re-create the archives. GNU tar supports both formats. However, I haven't found an easy way to the conversion. How can I convert the existing gnu tar files to pax?

  • getAudioInputStream can not convert [stereo, 4 bytes/frame] stream to [mono, 2 bytes/frame]

    - by brian_d
    Hello. I am using javasound and have an AudioInputStream of format PCM_SIGNED 8000.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian Using AudioSystem.getAudioInputStream(target_format, original_stream) produces an 'IllegalArgumentException: Unsupported Conversion' when the target_format is PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian Is it possible to convert this stream manually after every read() call? And if yes, how? In general, how can you compare two formats and tell if a conversion is possible?

  • How do I change a Git remote HEAD to point to something besides "master"

    - by jhs
    Short version: How do I set a Git remote's HEAD ref to point to something besides "master"? My project has a policy not to use a "master" branch (all branches are to have meaningful names). Furthermore, the canonical master repository is only accessible via ssh://, with no shell access (like GitHub or Unfuddle). My problem is that the remote repository still has a HEAD reference to refs/heads/master, but I need it to point to a different branch. This is causing two problems: When cloning the repo, there this, warning: remote HEAD refers to nonexistent ref, unable to checkout. That's confusing and inconvenient. The web-based code browser depends on HEAD as a basis for browsing the tree. I need HEAD to point to a valid branch, then.

  • Extend MySQL implementation of PiP Algorithm?

    - by Mike
    I need to make a point in polygon MySQL query. I already found these two great solutions: http://forums.mysql.com/read.php?23,286574,286574 MySQL implementation of ray-casting Algorithm? But these functions can only check if one point is inside a poly. I have a query where the PiP part should only be one part of the query and check for x points inside a polygon. Something like this: $points = list/array/whatever of points in language of favour SELECT d.name FROM data AS d WHERE d.name LIKE %red% // just bla bla // how to do this ? AND $points INSIDE d.polygon AND myWithin( $points, d.polygo ) // or UPDATE I tried it with MBR functions like this: SET @g1 = GeomFromText('Polygon((13.43971 52.55757,13.41293 52.49825,13.53378 52.49574, 13.43971 52.55757))'); SET @g2 = GeomFromText('Point(13.497834 52.540489)'); SELECT MBRContains(@g1,@g2); G2 should NOT be inside G1 but MBR says it is.

  • Fastest way to find the closest point to a given point in 3D, in Python.

    - by Saebin
    So lets say I have 10,000 points in A and 10,000 points in B and want to find out the closest point in A for every B point. Currently, I simply loop through every point in B and A to find which one is closest in distance. ie. B = [(.5, 1, 1), (1, .1, 1), (1, 1, .2)] A = [(1, 1, .3), (1, 0, 1), (.4, 1, 1)] C = {} for bp in B: closestDist = -1 for ap in A: dist = sum(((bp[0]-ap[0])**2, (bp[1]-ap[1])**2, (bp[2]-ap[2])**2)) if(closestDist > dist or closestDist == -1): C[bp] = ap closestDist = dist print C However, I am sure there is a faster way to do this... any ideas?

  • can the point have a longer history

    - by stevejb
    Hello, I often find myself in the following situation. Say I was editing a file with this contents \begin{itemize} \item \end{itemize} I really like http://stackoverflow.com ! And say the point was after the word \item. What I want to do is select http://stackoverflow.com , C-w it, and go back to \item, and yank it there. What I would do is C-s htt and that would bring the point to the 2nd t of http, and from there I would go backwards, C-SPC on h, then select the rest of the word. Now, I would like to use something like C-x C-x to bring me back to \item, but it will instead bring me back to the h of http. Is there a command like C-x C-x which brings the point back through its history of location? Thanks,
