We’re looking for a ColdFusion developer to join our team of 15 developers and designers at WhiteLabelDating.com. We’re focused on creating the very best online dating platform in the industry. We’re highly profitable, growing quickly and want to recruit the best people to work with our experienced team and be a part of our future.

We’re based at 1 High Street in the centre of Windsor, west of London. We’re easily commutable from London (West from Paddington or South-West direct from Waterloo), Reading, Staines or Slough.

Our core application is written ColdFusion and we’re looking for someone to join the team to help maintain and improve all areas of the code. This would be an ideal role for an intermediate level developer looking to improve their skill set and also diversify into other languages and frameworks such as Ruby on Rails. We are currently investigating architecture changes and someone with an interest in cloud computing, sphinx and highly available database systems would be a great asset.

Now the majority of our SSL certificates for the site in question are server out via a SSL accelerator on our Cisco LBAL’s but this site wasn’t. It was still using a cert on the local box. Having dug deeper I noticed that a couple of the servers had the following lines of code in whereas all the others didn’t. Due to the load balancing that solves the randomness side of it.

AddType application/x-x509-ca-cert .crt
AddType application/x-pkcs7-crl .crl
SSLPassPhraseDialog builtin
SSLSessionCache shmcb:/var/cache/mod_ssl/scache(512000)
SSLSessionCacheTimeout 300
SSLMutex default
SSLRandomSeed startup file:/dev/urandom 256
SSLRandomSeed connect builtin
SSLCryptoDevice builtin

Something in those lines of code causes the issues, I’m stabbing in the dark that it’s the session cache as none of the others would seem to be causing the problem. I’ve not tried line by line to find the offender.

Hopefully that will help someone out as I found lots of results in Google but not many solutions!

Currently our setup has a MySQL 5.0.x master running with quite a few slaves. The setup is OK but isn’t as scalable as we’d like. The master isn’t suffering load wise so we don’t need to look at distrubtion masters or get into pyramid replication which is just a bit too complex. The main hang up is searching. We have members, each member has loads of related details, photos, payments, messages, profile information etc and currently it’s spread out over a number of tables. We’ve looked at sphinx, hadoop, solr / lucence but aren’t sure if those kinds of things can be used for multi faceted objects. We don’t want a plain text search because the data is mostly lots of numbers like height, age, hair colour all picked from lookup tables but maybe we can combine our data into some form of index that is better for searching? Currently we flatten the most searched data out into single tables (split on certain categorizations) and search those the details in them are updated regularly by triggered actions in the application. Memcache is an option as we use it to store data already.

MySQL 5.4 looks great in the performance enhancements it could bring but that’s now not looking like it’s going to be coming until around December. I hope Sun release it sooner however as the inital peek at it we’ve had seem to back up Sun’s claims.

Any ideas / suggestions / experience would be appreciated. Comment or email me.
