Comment on Hashcash by Simon Rycroft

Thanks for the offer Guilio, but it will never be possible to alter the hashcash algorithm so that it doesn’t trigger a slow script warning, it’s meant to be a slow script.

Hello Simon, I would like to confirm that version 1.4 seems to work great!

I am still willing to help you in implementing the Javascript algorithm in a way that will not trigger the “slow script” warning; this will allow the option to set the toll cost per site/page (possibly in the module’s settings).

Thank you very much for your work.

Hello Simon,

I have just tried to submit a new comment on our site, and I am alway getting a “Your hashcash string is not valid. Are you a spammer?” error message. :-(

How should I proceed to diagnose this issue?

Hello Simon,

after a few spam messages posted during the first few hours after I installed the hashcash module, nothing else has been submitted.

So my complains are almost gone.

If you would like to improve the hashcash implementation (I suppose done in Javascript) to avoid the “slow script” warning I think I can provide you some good advices, as I have already done it for my own service.

Thank you very much for your reply

Unfortunately if you increase the toll of the module the majority of clients I tested complain of a "slow script" resulting in the code not being executed when the user selects to stop the script. I actually suspect that the module may not be set up correctly on your site, can you post some information to the project's Drupal page.

Hello Simon,

I am a great fan of hashcash, and I have used it extensively on our service.

Thanks to a comment of one of our users, I have found your hashcash module for Drupal, and I have installed it in place of the captcha modules.

The problem is that in the first couple of ours, I have got already three spam messages. :-(

Is it possible to tune the cost of the toll the hashcash is requesting? Is there anything else I should do to improve the efficacy of your module?

Sadly I think I spoke too soon. I’ve received a few spam comments even with this plugin. Askimet has been turned back on!

Comment on Contacts server? by simon

Very interesting Marty, the Symas site is quite awful to navigate around, which doesn’t say much for the software they’re providing. I’m not looking for a closed source fully packaged LDAP server, I’m more than capable of getting OpenLDAP working myself, I just find the whole LDAP protocol for saving a few contacts on a server a little OTT. LDAP is intended for the enterprise, which I certainly am not.

Well, a basic installation of OpenLDAP is probably smaller than the other database you’d install and offers, out of the box, solid security and excellent performance. There are numerous HOWTOs on how to set up a contact list and connect it to client applications and no new development is required.

You can download a pre-build binary version of OpenLDAP with OpenSSL, Cyrus SASL, and BDB all coordinated and tested from http://www.symas.com for FREE (Linux and most Unix platforms, Windows coming).
