Parse on their ditching-Rails story. I haven’t heard a nice thing about Ruby or Rails as an operational, production-quality platform in a long time :(
we are introducing Flow Logs for the Amazon Virtual Private Cloud. Once enabled for a particular VPC, VPC subnet, or Elastic Network Interface (ENI), relevant network traffic will be logged to CloudWatch Logs for storage and analysis by your own applications or third-party tools. You can create alarms that will fire if certain types of traffic are detected; you can also create metrics to help you to identify trends and patterns. The information captured includes information about allowed and denied traffic (based on security group and network ACL rules). It also includes source and destination IP addresses, ports, the IANA protocol number, packet and byte counts, a time interval during which the flow was observed, and an action (ACCEPT or REJECT).
‘[Tim Hunt] said that while he meant to be ironic, he did think it was hard to collaborate with women because they are too emotional – that he was trying to be honest about the problems.’ So much for the “nasty twitter took my jokes seriously” claims then.
Good post, and hard to disagree.
One of the “features” of systemd is that it allows you to boot a system without needing a shell at all. This seems like such a senseless manoeuvre that I can’t help but think of it as a knee-jerk reaction to the perception of Too Much Shell in sysv init scripts. In exactly which universe is it reasonable to assume that you have a running D-Bus service (or kdbus) and a filesystem containing unit files, all the binaries they refer to, all the libraries they link against, and all the configuration files any of them reference, but that you lack that most ubiquitous of UNIX binaries, /bin/sh?
ouch, really sounds like Storm didn’t cut the muster. ‘It’s hard to imagine something more damaging to Apache Storm than this. Having read it through, I’m left with the impression that the paper might as well have been titled “Why Storm Sucks”, which coming from Twitter themselves is quite a statement.’ If I was to summarise the lessons learned, it sounds like: backpressure is required; and multi-tenant architectures suck.
