vlowther··on Linux Problems on the Desktop (2018)
You have a very limited imagination. Wireshark is regularly attacked -- it parses random data it gets off the network, therefore it can be attacked using deliberately malformed packets. See https://www.wireshark.org/security/ for more info.
vlowther··on Study shows massive insect loss
The study cited in the paper was carried out on Puerto Rico. There isn't exactly another more suitable climate to migrate to.

Bash, but...

vlowther··on Show HN: Dr-provision, a single binary system provisioning solution
One of our demo workloads deploys Kubernetes via kubeadm on bare metal nodes -- we have a video of the process here: https://www.youtube.com/watch?v=OMm6Oz1NF6I
vlowther··on Show HN: Dr-provision, a single binary system provisioning solution
Hi, I am one of the lead engineers developing dr-provision. We have a few interesting features:

* Written in Go, for that single binary install goodness.

* Stackable read-only content layers, to make change control of your provisioning infrastructure easy. We also provide several content layers that include common provisioning tasks such as installing Ubuntu, Centos and Debian, performining initial system discovery and inventory, and a bunch of other stuff.

* Full REST API. All aspects of dr-provision are managed via our REST API, and we also provide a CLI interface and a React-based Web UI.

* Integrated DHCP, TFTP, static HTTP and BINL servers. No need for dnsmasq, tftpd, or nginx.

* Tasks and Workflows: You can define provisioning workflows to manage all aspects of provisioning a system, from initial system discovery through installing your OS to handing control of the system off to Ansible/Chef/Puppet.

vlowther··on Universally Unique Lexicographically Sortable Identifier in Go
That was bad and you should feel bad. :)
vlowther··on Leonard Cohen Has Died
Hah. Closing Time was the last song at mine.
vlowther··on What we learned in Seoul with AlphaGo
Until very recently, the usual sorts of AI really sucked at winnowing through the stupidly broad and deep state trees go has. This is really a nice demonstration of how quickly modern AI has advanced.
vlowther··on AlphaGo beats the world champion Lee Sedol in first of five matches
Your assertion that the universe has infinite anything is a common mistake. A stupidly large number of states is not infinite.
vlowther··on The Meditations by Marcus Aurelius
A better (if more time consuming) option is to learn Latin and read it in the original.
vlowther··on SICL – A fresh implementation of Common Lisp
That nil does double duty as boolean false and shorthand for '(). Scheme got it right with #f not being the same thing as '()
vlowther··on Docker 0.9: introducing execution drivers and libcontainer
Reporter here. I just have everyone use the devicemapper backend for everything.
