• good/full Boot Spirit examples using version 2 syntax

  - by bpw1621

  Almost all of the examples I've gone and looked at so far from: http://boost-spirit.com/repository/applications/show_contents.php use the old syntax. I've read and re-read the actual documentation at http://www.boost.org/doc/libs/1_42_0/libs/spirit/doc/html/index.html and the examples therein. I know Joel is starting a compiler series on the blog http://boost-spirit.com/home/ but that hasn't gotten in full swing yet. Any other resources to see worked examples using some more sophisticated/involved aspects in the context of fully working applications?

• LESS CSS on Windows

  - by Mojave Storm

  Trying to set up LESS for css (see http://lesscss.org/index.html) on my Windows box, and I've installed ruby and rubygems and I've followed the instructions here (http://lesscss.org/docs) exactly. I have a file 'teststyle.less' in C:\ and in command when I type lessc teststyle.less to compile into a .css file, I get the error "The filename, directory name, or volume label syntax is incorrect." Out of those familiar with LESS, do any of you have a solution to my problem? Did I mess up the install? Thanks -Mojave Storm

• make local only daemon listening on different interface (using iptables port forwarding)?

  - by UniIsland

  i have a daemon program which listens on 127.0.0.1:8000. i need to access it when i connect to my box with vpn. so i want it to listen on the ppp0 interface too. i've tried the "ssh -L" method. it works, but i don't think it's the right way to do that, having an extra ssh process running in the background. i tried the "netcat" method. it exits when the connection is closed. so not a valid way for "listening". i also tried several iptables rules. none of them worked. i'm not listing here all the rules i've used. iptables -A FORWARD -j ACCEPT iptables -t nat -A PREROUTING -i ppp+ -p tcp --dport 8000 -j DNAT --to-destination 127.0.0.1:8000 the above ruleset doesn't work. i have net.ipv4.ip_forward set to 1. anyone knows how to redirect traffic from ppp interface to lo? say, listen on "192.168.45.1:8000 (ppp0)" as well as "127.0.0.1:8000 (lo)" there's no need to alter the port. thanx

• Add querystring parameters to link_to

  - by Craig

  I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.

• UIView "suck" animation

  - by igul222

  I'd like to use the UIView "sucking" transition (view is "sucked" into a point) referenced here: http://iphonedevwiki.net/index.php/UIViewAnimationState#Using_suckEffect The method above, however, uses private APIs, which makes it next to useless for an App Store app. How can I recreate a similar effect without relying on private APIs? I'm guessing the answer has to do with OpenGL, although I have zero experience there.
