Question2Answer Number Captcha
I’ve been using Question2Answer for a number of years now to power Ask Planet Kubb. I like Question2Answer because it is simple to run, uses a standard PHP + MySQL setup and can even be used in a multi-site farm configuration easy enough. However, I’ve been frustrated by it’s ability to manage spam registrations.
Question2Answer has built in support for ReCaptcha and it has a plugin method to use other anti-spam measures. I’ve used ReCaptcha for a while, but it results in 4 to 10 spam registrations a day. I tried switching to the Q2A Logical Captcha by amiyasahu which uses Text Captcha. I even submitted a pull request to properly salt the captchas. But this resulted in 3-4 times the spam registrations as ReCaptcha! Ouch!
I decided to apply the same type of spam defense I’ve successfully used for MediaWiki and early results are great. It uses the Numbers_Words PHP package to spell out a number of nine digits and then ask the user to identify the number in a specific position. The question looks like this:
This works really well. You can grab q2a-number-captcha and git clone it for your own use.

Awesome! AWS container service!
AWS is first cloud platform with container support. Yes?
Some CLI geekdom in the AWS re:Invent keynote. Nice!
Impressive Docker AWS container demo at re:Invent!
AWS Lambda announced! AWS Lambda has big potential for #TeamSPS!
Skrillex performing at re:Play!
Expecting a packed Lambda breakout session at re:Invent!
AWS #reinvent should hand out copies of Strucuture of Computer Programs to celebrate Lambda.
Love AWS Lambda bringing cloud scale to functional workloads. Opens up amazing potentials.
Lots of buzz in conversations about Lambda.
Wonder how long until social feeds like Gnip allow connecting AWS Lambda functions. Seems obvious.
Line for AWS ECS session is insane.
At the most in-demand re:Invent session of AWS Container Service. Packed!
Every session at re:Invent touching on containers or Docker have been completely full with lines out the door.
When did “fleet” overtake the term “farm”. Tertiary impact of all this container talk?
The Container Service slides seem to have gone without review from the AWS brand managers. 🙂 Refreshing actually.
“Server farm” v “server fleet”. Fleet sounds bigger. Better to be transportation system than farmers?
Very cool elastic container service demo.
AWS re:Invent - Day 1
Seated for AWS re:Invent keynote!
Andy Jassy “Cloud has become the new normal.” True for many!
“shower cycles”? New term to me.
Amazon Aurora looks compelling.
Impressed by first day keynote and all the work going on!
At the re:Invent Security Keynote. AWS capabilities for security has radically changed and improved in recent years. AWS has 5 to 7 thousand instances running continual security tests against internal systems constantly.
Lunch for 9,500.
You will not miss Michael Ducy. Very sparkly!
Nice demo of Datadog.
Attending impressive session on Key Management in AWS with Amy Patton. Wishing Milinda Rambel Stone, our security leader for #TeamSPS, was here too!
AWS re:Invent - Day 0
Looking forward to connecting with the rest of #TeamSPS at #reinvent!
68 °F and the cab driver had the heat on. Opened window. #vegas
Hotel is pretty full so got upgraded to a suite. Nice digs.
“These Days” by Foo Fighters really cannot be too loud.
Yard is ready for snow with 15 minutes of daylight to spare.
Being able to AirDrop from my iPhone to my MacBook is surprisingly useful.
