I don't know of it's the reason, but inet_aton[0] and other parsing libraries that match its behaviour will parse 1.1 as 1.0.0.1. I use `ping 1.1` as a quick connectivity test. [0] https://man7.org/linux/man-p

This used to be me until I started using screenshot shortcuts that put images in the clipboard instead of files. You can paste directly into jira, slack, hangouts, whatsapp web, and many other places.

Author here. Those are great tips, thanks! I actually just installed evolve from pip last night. I'll probably borrow from your hgrc, or at least let it inspire me :-) > I'm in the opposite boat where I've used mercurial f

And you get 4 extra cores and 24 gigs of ram "for free" vs i3.16xl (which is what we use). I think we looked into switching but it wasn't clear if the reservations could be switched over.

Yup, that's the blog post I mentioned in the intro. Sometimes obsessively reading HN pays off. Even if it's a year later... :-)

Back when we ran the Citus cluster on EBS, we lost some EBS volumes as well. This manifested as disk not responding, followed several days later by an email from AWS with the subject Your Amazon EBS Volume vol-123456789abcdef telling you

Post author here. It's ephemeral, yes. It survives reboots, so that's not a problem. It doesn't survive instance-stop, so if a machine is being decommissioned by AWS we do indeed lose its data. As for how we protect against i

Hi post author here! First off, we actually do use RDS for other databases. As you point out, having a lot of the operational stuff taken care of for you is great. The post is specifically about our Citus cluster, which stores the analytics

Post author here, happy to answer any questions. Looking into this one was fun, especially actually looking at the vDSO source instead of just thinking of it as "the makes gettimeofday syscall fast thing".

I'm curious why chroot is used instead of mount namespace and pivot_root(2). This would let them get away without CAP_SYS_CHROOT, while also providing stronger filesystem isolation.

Honest question: how do people use influxdb for monitoring and alerting? Our metrics feed into influx, and I cannot get answers to simple questions like “what is the failure rate” because arithmetic across measurements isn't possible [

Here's an issue: https://github.com/hashicorp/terraform/issues/15263

by kalmar 9y ago
Oh interesting. Note to self: see if there's an option to disable `terraform apply` without a plan. I always refresh when running the pre-apply plan, but while iterating I use that. Do you always run your `tffreshplan` command before a

I don't think it would work in this case, as the `ebs_block_device` block isn't a resource. In fact, the TF state doesn't even have the volume IDs for them! An alternative to doing this was `terraform import` on all the volum

by kalmar 9y ago
That's pretty cool. So is the model that you don't manage the volumes in TF at all? (Btw I think I know people you know... also in Montreal and I know a couple folks at AdGear!)

(OP here) I think that would be a useful thing to do in some situations, but it often won't get what you'd like. There's no guarantee that a view will ever call it's superclass' implementation, so inserting code has

Now I want to learn about stack probes!

by kalmar 10y ago
Ah so the idea is that there's already 8 KB of actual pages set for stack by this point. So when I try to get another (8 MB - 8 KB + 1 B), that blows things up? I wonder if I can watch this happen in /proc/$pid/maps or s
