No, this is not a real Sinatra error :).
This is the personal homepage of Elad Meidar, a web developer and an entrepreneur specializing in Ruby on Rails. I hang around in Israel, and i am currently having the best time of my life over at Fiverr.com
I am a proud member of RailsBridge, Helping new Rails developers get into our world and also contributed a few Patches to the Ruby on Rails core.
Most web applications that i know, are based on interpreted script languages (PHP, Ruby, Python) and some are compiled (.Net, Java). The complied languages often (if not always) come with a full environment, IDE and a debugger for the server side code, the interpreted languages aren’t and the developer is more than ofter required to load the application and page in order to check for syntax error and use debug prints as the most basic tool of debugging.
here we go:
The ultimate solution – Firebug addon
ok, i know what you might say: “it’s a FIREFOX addon!, how can it be THE ultimate solution?”.
Well, good news.
Internet Explorer – Evil, annoying, can’t we just drop it?
DebugBar – Firebug’s little brother
debugbar is a nice Firebug mockup for IE, simple but not as strong as Firebug. problems are that it’s not free, and you’ll have to install a whole lot of crap on your computer. too bad.
The IE Developer Toolbar is a poor attempt to find a solution for some of the problems facing a web developer when dealing with IE, but at least it’s something.
Safari – When i am not working, that’s the one.
*by saying Safari, i mean the MacOS one, not that fucked up Windows version, yak.
Safari came from Apple, so it’s probably padded with thought, intention and considiration to any kind of end-user, as well as a developer.
The Safari developer tools are nice, from a very descriptive, good looking Console and Network stats, to a rendering engine that can mimic other browsers (although i am not sure how good it is.).
FireFox – by the developers, for the developers
Two addons you’ll have to pay attention to are the Web Developer toolbar addon, and Firebug we’ve mentioned before.
You're seeing this error because I think it is funny.
