Syncthing is becoming Pulse. Pulse replaces proprietary sync and cloud services with something open, trustworthy and decentralised. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party, and how it's transmitted over the Internet.

Adrian Cockroft's Cloud Outage Reports Collection
The detailed summaries of outages from cloud vendors are comprehensive and the response to each highlights many lessons in how to build robust distributed systems. For outages that significantly affected Netflix, the Netflix techblog report gives insight into how to effectively build reliable services on top of AWS. [....] I plan to collect reports here over time, and welcome links to other write-ups of outages and how to survive them.

Video Processing at Dropbox
On-the-fly video transcoding during live streaming. They've done a great job of this!
At the beginning of the development of this feature, we entertained the idea to simply pre-transcode all the videos in Dropbox to all possible target devices. Soon enough we realized that this simple approach would be too expensive at our scale, so we decided to build a system that allows us to trigger a transcoding process only upon user request and cache the results for subsequent fetches. This on-demand approach: adapts to heterogeneous devices and network conditions, is relatively cheap (everything is relative at our scale), guarantees low latency startup time.

DropBox outage post-mortem
A bug in a scheduled OS upgrade script caused live production DB servers to be upgraded while live. Fixes include fixing that script by verifying non-liveness on the host itself, and a faster parallel MySQL binary-log recovery command.

Scaling lessons learned at Dropbox
website-scaling tips and suggestions, "particularly for a resource-constrained, fast-growing environment that can’t always afford to do things “the right way” (i.e., any real-world engineering project". I really like the "run with fake load" trick; add additional queries/load which you can quickly turn off if the service starts browning out, giving you a few days breathing room to find a real fix before customers start being affected. Neat

Dropbox dedupe feature allows materialization of any file, if you know its hash
'allows users to exploit Dropbox’s file hashing scheme to copy files into their account without actually having them. Dropship will save the hashes of a file in JSON format. Anyone can then take these hashes and load the original file into their Dropbox account using Dropship.' heh. that sounds very familiar, I seem to recall thinking about this problem on several occasions... ;) Dropbox certainly didn't like it, going by this account

'Lsyncd uses rsync to synchronize local directories with a remote machine running rsyncd. Lsyncd watches multiple directories trees through inotify. The first step after adding the watches is to rsync all directories with the remote host, and then sync single file by collecting the inotify events. So lsyncd is a light-weight live mirror solution that should be easy to install and use while blending well with your system.' (via adulau)
