Free and Open Source Software Developers' European Meeting
tuan t. pham
#Saturday, Febuary 4
##Software Heritage
Speaker: Stefano Zacchiroli, Roberto Di Cosmo
Software must written for people to read, and only incidentally for machine to execute.
Think of it as Project Gutenberg of Human Written Software meets
WaybackMachine/Archive. Source for the Win!
Source code provides a view into the mind of the designer, Len Shustek.
##Sysdig Analysing log data
/dev/null is available everywhere. Let's write to it. Clever Hack!
Tools: sysdig, csysdig
Source: https://github.com/draios/sysdig
##Backup and disaster Recovery Bareos, ReaR, Relax and Recovery...etc. Using scripts to take snapshot of the system and recover when disaster strike.
#Sunday, Febuary 5
##Scaling Graphite At Booking.com, there are a lot of metrics to collect. In order to scope with the large amount of data, the traditional Graphite software stack is redesigned in order to scale. Vladimir Smirnov gives a brief talk on how they did it.
###Initial Thought
| Legacy Graphite Component | New component |
|---|---|
carbon-relay.py |
carbon-c-relay |
carbon-c-relay: written in C, routes 1M data points per second using only 2
cores.
The key with scaling is that carbon-[c]-relay is Single Point Of Failure.
It's hard to scale when there are requirements of Fault-tolerance and High
Availability. So the team at Booking redesign the Graphite Stack using
carbonzipper, carbonserver, and go-carbon.
###Redesign the Graphite software stack
| Legacy Graphite Component | New component |
|---|---|
carbon-cache.py |
carbonzipper + carbonserver + go-carbon |
The beautiful new software stack looks like this:
###SourceCode on github.com
| Component | URL |
|---|---|
carbonzipper |
https://github.com/dgryski/carbonzipper |
carbonserver |
https://github.com/grobian/carbonserver |
carbonsearch |
https://github.com/kanatohodets/carbonsearch |
go-carbon |
https://github.com/lomik/go-carbon |
carbon-api |
https://github.com/dgryski/carbonapi |
carbon-c-relay |
https://github.com/grobian/carbon-c-relay |
Another thought: IPv6 on Android just works with Android 6.x version.
