For designers working with css, going to the command line can be daunting. So you could wrap this in a nice app on the dock or the menu bar, and maybe you'd like a couple of euro for your time and writing some support documentation..
I know :) The comment made me smile because I wrote the script for a client who is a designer.
I used to use the ipfw commands directly. I didn't want the client to remember the syntax and also starting and stopping the throttling involved a couple of commands which can go wrong. So I wrote this and also had some default values so that he can just do throttle start and throttle stop
i believe this tool (and the one in Lion/XCode) uses ipfw+dummynet, which is available also for linux/openwrt and windows at http://info.iet.unipi.it/~luigi/dummynet/ (you can find also some documentation material there).
Sure. You can add jitter, packet loss, duplication, corruption, shaping, reordering, prioritisation. This page has examples: https://www.linuxfoundation.org/collaborate/workgroups/netwo... (netem is the kernel framework, it is to tc what netfilter is to iptables). The examples apply to outgoing traffic, search for ifb0 for a way to apply them to incoming traffic.
Seems to be a trend to wrap a lesser known commandline tool in a cocoa app and knock it out for a couple of quid to arts graduates. Someone did a cocoa version of guard recently. That other guy tried to make a system preferences pane for the hostfile, but apple wouldn't let him. I'm sure there have been others.
At least this guy has the decency to point out that it's already built into OS X right there on the landing page ;)
If you need to do this stuff to a saturated gigabit pipe in both directions, then may I suggest the superbly named 1U Network Nightmare, yours for only $9999.
Hi guys, I'm the developer of the application.
Thank you for all your comments. I'll take them into consideration while trying to improve the rough edges and missing features of Slowy for the next update.
I'll update the website soon (http://slowyapp.com), completing the FAQ section and adding a new blog section.
