So recently I had the opportunity to present to the ElasticSearch Meetup Group hosted at Atlassian to talk about how HipChat scaled to 1 Billions messages. Below are video and the slides from the talk, hope you enjoy.
We at Oxygen Cloud are always looking at ways to make the cloud more personal. A while back we stumbled over the Backblaze blog talking about “How to build cheap cloud storage” and it gave us an idea! What if we get one, but turn it up the volume to 11 by integrating the Backblaze into the Oxygen Cloud?
This is what 55TB looks like! Continue reading
So a few days ago the wife was reporting problems with her e-mail and one of those e-mails she was having problems with was groupon. So I decided to take a look at the e-mail headers to figure out when they were sent and I found this little gem.

It’s a cute trick to get people who understand headers to be interested in the company.
Did I forget to mention that we at Oxygen Cloud are hiring, http://www.oxygencloud.com/careers.html
As more and more things move to the “cloud” as a Sys Admin you might find your self tasked with managing a Database that you don’t have shell access too. That has been the case for me with my last two jobs, Laughing Squid and now as Senior Sys Admin at Oxygen Cloud. With Oxygen we needed to backup some AWS RDS Instances and wanted to do it using a server on EC2 so we don’t have the bottle next of our local internet. This same method works with Rackspace Cloud Sites which I used at Laughing Squid. Its use a little known (could not find it easily with a google search) trick with mysqldump
mysqldump -P <port#> -h <server ip>-u mysql_user -p database_name table_name > backup.sql
To restore your DB in the cloud you use a more well-known mysql technique
mysql -u mysql_user -p -h <server ip> cloud_db_name < backup.sql
Looks like the iPhone stores GPS data on you to your local backup (and maybe apple) and you can now view it using iPhoneTracker. Scary and the history mode is even more scary as you can see where you went during a day and its pretty accurate.
