  • How should I migrate a site from ZWiki to MediaWiki?

    - by Dan L
    I have a fairly extensive wiki on ZWiki on Zope (in turn on Plone). Most pages are in reStructured text format, but there are several in straight HTML as well. What is the best approach to migrate those pages over to a MediaWiki wiki with pages converted to MediaWiki and HTML formats? Of course I'd like to automagically convert all links (internal and external).

  • Basic LaTeX questions

    - by bpc89
    Two (hopefully quick) questions about LaTeX: How do you number select functions? I'm working in a documentclass{article}, if that matters. I want to have certain functions numbered such as function1 function2 (1) function3 function4 (2) How do you make a sign to evaluate an integral? I know how to do brackets, but is it possible to only make one straight light to the right of the function with the bounds of integration? I can't figure out how to do that.

  • Are there any modern GUI toolkits which implement a heirarchical menu buffer zone?

    - by scomar
    In Bruce Tognazzini's quiz on Fitt's Law, the question discussing the bottleneck in the hierarchical menu (as used in almost every modern desktop UI), talks about his design for the original Mac: The bottleneck is the passage between the first-level menu and the second-level menu. Users first slide the mouse pointer down to the category menu item. Then, they must carefully slide the mouse directly across (horizontally) in order to move the pointer into the secondary menu. The engineer who originally designed hierarchicals apparently had his forearm mounted on a track so that he could move it perfectly in a horizontal direction without any vertical component. Most of us, however, have our forarms mounted on a pivot we like to call our elbow. That means that moving our hand describes an arc, rather than a straight line. Demanding that pivoted people move a mouse pointer along in a straight line horizontally is just wrong. We are naturally going to slip downward even as we try to slide sideways. When we are not allowed to slip downward, the menu we're after is going to slam shut just before we get there. The Windows folks tried to overcome the pivot problem with a hack: If they see the user move down into range of the next item on the primary menu, they don't instantly close the second-level menu. Instead, they leave it open for around a half second, so, if users are really quick, they can be inaccurate but still get into the second-level menu before it slams shut. Unfortunately, people's reactions to heightened chance of error is to slow down, rather than speed up, a well-established phenomenon. Therefore, few users will ever figure out that moving faster could solve their problem. Microsoft's solution is exactly wrong. When I specified the Mac hierarchical menu algorthm in the mid-'80s, I called for a buffer zone shaped like a <, so that users could make an increasingly-greater error as they neared the hierarchical without fear of jumping to an unwanted menu. As long as the user's pointer was moving a few pixels over for every one down, on average, the menu stayed open, no matter how slow they moved. (Cancelling was still really easy; just deliberately move up or down.) This just blew me away! Such a simple idea which would result in a huge improvement in usability. I'm sure I'm not the only one who regularly has the next level of a menu slam shut because I don't move the mouse pointer in a perfectly horizontal line. So my question is: Are there any modern UI toolkits which implement this brilliant idea of a < shaped buffer zone in hierarchical menus? And if not, why not?!

  • Well tested C/C++ lock free queue?

    - by uj
    I am looking for a well-tested, publicly available C/C++ implementation of a lock free queue. I need at least multiple-producers/single-consumer functionality. Multiple-consumers is even better, if exists. I'm targetting VC's _Interlocked... intrinsics, though anything which is straight forward to port would be fine. Could anyone give any pointers?

  • Geometry library for python (or C++) for CAD-like operations?

    - by gct
    I'm trying to put together a simple program that will let me visualize a series of consecutive cuts on a wood panel using a router with a particular cutting head. I'm trying to find a decent geometry library that will give me a shortcut through the CAD-like stuff. Specifically, I'd like to be able to define a rectangular solid (the wood panel) and then define a bit profile shape, and take cuts through the rectangular solid (sometimes on a straight line, sometimes on a circular arc). Does anyone know of anything that will do this?

  • Best way to check for string in comma-delimited list with .NET?

    - by Jeremy Stein
    I'm reading a comma-delimited list of strings from a config file. I need to check whether another string is in that list. For example: "apple,banana,cheese" If I check for "apple" I should find it, but if I check for "app" I should not. What's the most straight-forward and concise way to do this? It doesn't have to be fast. (I'll add my solution as an answer, but I'm hoping someone has something better.)

  • How to autodoc .Net Google code projects?

    - by Remus Rusanu
    I know how to generate html documentation using Sandcastle and similar tools. But if I want to host the project on Google code, how can I easily publish the documentation straight into the Google project Wiki pages? I can see the SVN repository has a wiki folder which I assume maps to the project Wiki pages and I guess I can make a build step to build the documentation from the autodoc tags. But is there some tool that generates wiki compatible format from the code documentation tags?

  • Make a table row's text editable immediately

    - by Ricky
    I have an NSTableView in my user interface, where new rows are added when the user presses a button or keyboard shortcut. Each row consists of two text cells (the table is comprised of two columns). Is there a way to immediately select the first text cell of a new row which is added? So, basically, I would like the user to be able to press the button, adding a new row to the table and then having it editable straight away.

  • How to build a tree from a list of items and their children recursively in php?

    - by k1lljoy
    I have a list of items stored in the DB, simplified schema is like this: id, parent, name I need to generate a tree structure (in a form of a multi-dimensional array) that can be infinite levels deep. Top level items would have parent = 0. Next level down would have parent equal to the the id of the parent item, fairly straight forward. What would be the best way to do this, while consuming as little resources as possible?

  • Describe relative angles between points (like driving directions)

    - by aan234g
    I have a list of points with x, y coordinates. I know how to get the distance between points with sqrt(pow($x2 - $x1, 2) + pow($y2 - $y1, 2)) and the angle between points with atan2(y1 - y2, x1 - x2). How can I calculate the relative angle between the points (left, right, straight)? So, if I'm at point 1, what is the relative direction to point 2, then 2 to 3, 3 to 4, etc... Thanks for any help!

  • is there a way to designate the line token delimiter in Perl's file reader?

    - by Dr.Dredel
    I'm reading a text file via CGI in, in perl, and noticing that when the file is saved in mac's textEdit the line separator is recognized, but when I upload a CSV that is exported straight from excel, they are not. I'm guessing it's a \n vs. \r issue, but it got me thinking that I don't know how to specify what I would like the line terminator token to be, if I didn't want the one it's looking for by default.

  • Using low level api for datastore in google app engine ? is it bad ?

    - by Chez
    There is little documentation on how to use the low level api for datastore and quite a lot on JPA and JDO and how it translates to it. My question is: is there any advantage in coding against the JPA or JDO specs instead of accessing directly the low level api for datastore ? From an initial look, it seems simple and straight forward but I am not sure if there are good reasons why not to do it. Thanks Cx

  • Where does the query language sit within the MVC pattern?

    - by weesilmania
    I'd assume that since the query language sits within the controller (typically) that it belongs to that component, but if I play devil's advocate I'd argue that the query language is execute within the domain of the model, and is tightly coupled to that component so it might also be a part of it. Anyone know the answer? Is there a straight answer or is it technology specific?

  • Which version of .NET is available for Xbox 360?

    - by Rosarch
    I tried to look this up on MSDN, but couldn't get a straight answer. It says: The .NET Compact Framework for Xbox 360 implements a subset of the .NET Compact Framework, and has been optimized to take advantage of and expose the power of the Xbox 360. What exactly is the subset? Which version of the framework? 3.5? 2.0?
