I am not the author of G-WAN. I am not claiming to have done anything. This whole thread is based on a misunderstanding. G-WAN does not have any CAPTCHA support. The example merely demonstrates how to use G-WAN's image generation API. The C

Both you and the OP have misunderstood the purpose of the CAPTCHA example. See my post[1] for an explanation. [1] http://news.ycombinator.com/item?id=4113826

I do not have an example handy, so hopefully an explanation is enough. The CAPTCHA example has two parts: generating the CAPTCHA values and presenting them in a way that is easy for humans to solve, but difficult for computers. This example

The CAPTCHA example is incomplete. It is missing the part that actually makes it difficult for robots to solve. The purpose of the example was to provide a list of ways to implement an effective CAPTCHA.

G-WAN is not reserving sockets, it is being given access to more file descriptors. Any application which uses a large amount of file descriptors requires this.

Adding more servers costs money. Doing more with less saves money. See page 2 of http://gwan.ch/archives/g-wan_case.pdf .

The first can be proven with the provided benchmarking tool.[1] As for the second, I agree that the source of those "units sold" should be cited. [1] http://gwan.ch/source/ab.c

If you list the claims you feel are far fetched, I can try to provide evidence to support them.

I wrote the Lua, Go, and Python examples handlers. JavaScript, Lua, and Python can be linked directly with the server for performance you would not get via separate processes. I had more difficulty with Go, which you can read about on the f

Here are some reasons: * G-WAN is not open-source, so people (justifiably) resist trying it. * It lacks software that takes advantage of the platform. * G-WAN gets limited coverage on news sites. (it's banned from Wikipedia for exam

PHP support is important for backwards compatibility. This is one reason why I am implementing FastCGI. See [1] for reasons why PHP+FastCGI is a poor choice in 2012. [1] http://gwan.ch/en_fastcgi.html

G-WAN does not require any installation and you do not need to run it as root. If you run G-WAN as root, it will automatically apply certain optimizations such as giving itself access to more than 1024 sockets. Remove sudo and the examples

You do not have to pay any money to run G-WAN.[1] G-WAN is not merely a "hello world" server. See [2] for the API features and [3] for more details. [1] http://gwan.ch/download [2] http://gwan.ch/api [3] http://gwan.ch/archives/gwan_linux

Those features activate automatically in daemon mode. The manual explains it on page 7. Can you be more specific with your question? Perhaps these forum threads will help.[1][2] [1] http://forum.gwan.com/index.php?p=/discussion/393/how-to-d

The author of G-WAN provides a benchmarking script[1] you can use to test the claims for yourself. [1] http://gwan.ch/benchmark I have tested the claims and find them to be legitimate. If you have a more specific question, I may be able to

I have been using G-WAN for about a year. If anyone has specific questions regarding it, I will try to answer them.

If you are referring to the memory usage comparison at [1], the latest G-WAN version now uses less RAM than nginx. [1] http://nbonvin.wordpress.com/2011/03/24/serving-small-static...
