Hey, SharePoint Services (WSS) IS free. Microsoft Office Sharepoit Services (MOSS) isn’t, but for the purpose of an intranet site, WSS should do it. This is of course if you are using Windwos Server as a base… (which is not free). Edit: Here is a good comparison between WSS and MOSS.
Plurk.com uses Node.js for their Comet engine, they have a fairly high traffic load too. Blog post about Plurk using Node.js
Many SysAdmins use non-standard paths in order to avoid an easy-to-guess path in case of attacks. If you are building an Internet web server I suggest considering a non-standard path.
Whether it is “okay” or not depends on how sensitive the images are. If you are not using SSL, the URLs, HTML and the images themselves will be cached on your user’s computers.

If you specifically want to monitor an HTTP/HTTPS server and not just general connectivity (by way of ICMP), check out the EchoPingHttp and EchoPingHttps probes. There are also probes that will monitor DNS and SSH services. We use smokeping for general … Read more

Basically, python’s webserver is not configured to run php files by default, but instead of trying to reconfigure python’s web server, you can simply run php’s web server, which works almost exactly like python’s simplehttpserver, with php [options] -S <addr>:<port> [-t docroot] Example: php -S 127.0.0.1:80 -t … Read more
Okay, I have found the answer finally. The optimal number of Unicorn workers is not directly connected to the number of CPU cores, it depends on your load and internal app structure/responsiveness. Basically we use sampling profiler to determine workers’ state, we try to keep workers 70% idle and 30% doing the actual work. So, … Read more
