<p>Are there any open source or commercial web programming language that function much like Fog Creek's Wasabi? As in you write your web app in this parent language and it then compiles down to php for Linux hosts and ASP.NET for Windows hosts.</p>
| <p><a href="http://haxe.org/" rel="nofollow noreferrer">Haxe</a> is the closest I've seen, but it only compiles to PHP (and mod_neko), not to ASP.</p>
| <p>As far as I know, Fog Creek had to develop Wasabi because there wasn't such a tool. There are a few toolkits trying to be portable, but none that compiled to ASP or PHP that I know of (besides Wasabi, that is).</p>

<p>i dunno, but will your machine suffer great slowdown if you use a very complex regex?
like for example the famous email validation module proposed just recently? which can be found here <a href="http://ex-parrot.com/~pdw/Mail-RFC822-Address.html" rel="nofollow noreferrer">RFC822</a></p>

First I used regex but when I switched to using regular string functions it got a lot faster, like taking 40% of the time of the regex version. So while of course it depends, my thing got a lot faster.</p>

<p>I need to tweak some variables (only in a development setting) without having to restart IIS or anything (so I assume Web.Config is the wrong place to put them). Where is the easiest place to put about 500 config settings that have to be read for every request and written to, like I said, while IIS is running?</p>
... | <p>In a database?</p>
| <p>500 Config Settings to be read for every request? I'd put them in a database so they can be indexed and cached. A separate XML or data file would also most likely be cached in memory by the web server, but still wouldn't provide the performance an indexed database table could. But it depends on how you are access... | 22,759 |
