I have a legacy application that generates VRML 1.0 files. I'd like to build a WebGL-based web interface that can display these VRML files. Is there an easy way to do so?
Edit: Specified that they are VRML 1.0.
If you can get it to VRML 2.0 (VRML '97) using a tool like the above-referenced one from Parallelgraphics, you can use the Fraunhofer Institute's tools (see discussion and links to InstantReality at http://www.x3dom.org/?page_id=532) to go from VRML 2 to either X3DOM or X3D. With Firefox or Chrome and a current graphics card and driver, you've got the WebGL support needed to run X3DOM. X3DOM handles only a subset of X3D, but can be referenced straight from XHTML and CSS, or plug-ins required. It's at a much higher level and easier to deal with than dealing directly with WebGL.
As I understand it, X3D is a development from VRML, and there's a WebGL-based renderer for it called X3DOM. Converting over is unlikely to be zero-effort, but it might be easier than trying to make the jump all the way to a "native" WebGL format.
VRML can be pretty complex with lots of interactivity and it doesn't look like a ont-to-one converter is available. However, here is what you could try:
Convert your VRML file to a standard OBJ file using something like MeshConv
Import the converted file in CopperLicht (Free) or CopperCube (Not free)
You will then have some kind of conversion of your VRML file which you can fine-tune.

We have different forms of documentation for our desktop apps, but until now most iOS apps have been fairly self-explanatory so we've been able to get by with simple hint strings in settings etc.
But for a more complex app I'd like to be able to create a few HTML pages that look approximately like native iOS UI and are easy to maintain.
Dashcode has a browser template that seems to fit the bill, but it's terribly buggy under Lion. I could start from scratch using something like iUI, but I'm wondering if there isn't something readymade already out there that would fit the bill?
Requirements:
- One or possibly two levels of hierarchy
- Display short formatted text with images
- Preferably HTML so the documentation authors can create and format the content on their own without touching the dev side of things
Any ideas or tips would be appreciated!
I use CSS formatted HTML pages that can either be included in the project or served from the web or actually both (you can do a check so see if the app has a connection to the server and if so serve them up from there or serve them from a local resource).
I personally think the Static Cell UITableView is the ultimate way to display those help options. That and Storyboard were the two big favorites for me in iOS5.

I was looking for something to help me parse general meta-tags from websites similar to this github project I found for open graph data. Here's a demo app.
Basically, I'd like to be able to have a user input a URL from a news site and have it retrieve from that the Title, Desc, etc., leaving as little work possible for the user. Before I go roll my own I was wondering if there was a current project / gem that exists similar to the project above? (as it only works with open graph and not general meta-tags)
I also noticed that facebook's linter does this as well even without open graph specific tags.
I would recommend the Nokogiri gem. It is an HTML, XML, etc. parser so you can use it to parse pages on your own. The nice thing about this approach is that it affords you the most flexibility for your specific use case. You can use the gem to parse any meta and header tags as long as you can express them using XPath or CSS3 selectors.
You can also try this free (for most) Open Graph API that I built: http://www.opengraph.io/

Unfortunately, I can't use rtf2latex2e because it says that DropUNIX "no longer supports the classic environment". I barely know what I'm doing otherwise, besides dropping my .rtf file onto the DropUNIX program.
What else can I use? I don't mind which type of file it is I'm converting to LaTeX (.doc would also be OK, as long as it keeps my formatting).
I am using Mac OS 10.5.8.
Open Office can. Download it.
See the fmtconv question on the UK TeX FAQ, or, more specifically, the page on Converters from PC Textprocessors to LaTeX - Overview, which is specifically about this question and has many many examples. This general list of word-processor filters may help too.
UnRTF claims to be able to convert RTF to LaTeX as well as other formats (e.g. HTML). It claims to support HTML best, so perhaps RTF->HTML->LaTeX (e.g. with html2latex) might work better. I haven't actually tried any of this though.
Make your rtf/doc document into docx, and convert it using docx2tex.
You need the System.IO.Packaging .NET class to get this to work, which is no problem if you are using Windows, and is in principle supported by Mono if you are not. If anyone has success doing this with Mono, I'd like to hear of your experiences: this didn't work a year or so ago, but their implementation of that class has improved since then.
I say more about the utility in an answer at tex.stackexchange. Suffice it to say that I consider this by far the cleanest, most Latex-friendly option out there.

Are there any YAML parsers or YAML Serialization libs in Delphi?
I have recently started a Delphi-YAML project on BitBucket:
https://bitbucket.org/OCTAGRAM/delphi-yaml
At least, I've got something running, but there are many tests missing and there are probably many bugs hiding.
I don't know about a full YAML implementation, but JSON (a subset) is getting pretty popular and there are even some Delphi libraries listed on the JSON site. Delphi 2009 is even using (a slightly modified version of?) JSON in DataSnap.
http://sourceforge.net/projects/lkjson
http://www.progdigy.com/?page_id=6
http://sourceforge.net/projects/is-webstart/
May be it is high time to implement a YAML parser in Delphi...
Copy code from PyYAML (but Python is a dynamically typed language)
Or take a look at SnakeYAML which is written in a statically typed language (Java)
Free Pascal also has some json libs.
I garbled up something like this to interface with PHP once. Here is the code:
http://www.stack.nl/~marcov/phpser.zip
Note that it is more proof of concept than an usable lib.
This open source C# YAML parser looks like it could be a starting point for a Delphi implementation:
YamlDotNet - A .NET library for parsing and emitting YAML

I am looking for a web-based WYSIWYG (or WYSIWYM) editor like TinyMCE or WMD Editor (used to write this question) that supports users to write mathematical formulas. I have looked at LaTeX a little bit but it has a learning curve and I am not sure if support for MathML is extensive. Ideally I would also like to avoid having to rewrite an editor and would rather just pick one off the shelf.
Would like to know if any of you have dealt with a similar situation and what solution you adopted/built.
I was looking for something similar and came across this question. Then I was excited to find Mathquill, via the Wikipedia page on formula editors.
I've used a bunch of different formula editors, from MS Equation Editor to Google Docs' to LyX, and this is probably the most usable/fluid of all of them for simply banging out formulas. And it's web-based and GPL. This thing is much nicer than Google Docs' formula editor, at least.
Still leaves plenty of things to be desired, e.g. so far I've found: bolding, entering things like bra-kets, \hat, undo/redo history, mouse drag selection, etc. But I'm impressed by what's already in there. Anyway, it's just a few Javascript files, and on github.
http://www.dessci.com/en/ has the software to do exactly what you want.
I used texvc in a project a while back (what wikipedea uses) and it was reasonable, but it isn't really WYSIWYG. On the other hand, I prefer that since in many cases it's easier to specify what you mean than draw it.
see here DragMath
http://www.dragmath.bham.ac.uk/index.html
which is already used by Moodle and other sites.
And its Open Source
WIRIS would be another Javascript based visual math editor (commercial license required for some applications).
