Huh.
So, just now I learned that you can convert miles to kilometers with the Fibonacci sequence?
A mile is 1.609 kilometers.
The Golden Ratio, the ratio between Fibonacci numbers as they get large, is 1.618.
So, within about 1%. And large doesn't need to be that large, it's actually pretty accurate from about 8 onwards.
1 1 2 3 5 8 13 21 34 55 89 etc etc
5 miles is 8 km.
21 miles is 34 km.
89 miles is 144 km.
etc etc.
Kinda neat IMO.
Moving a VM from one hosting provider to another using:
* install new VM
* zfs send | zfs recv
* tar -c, scp, tar -x
* some copy/paste
* finding a bug in the FreeBSD image.

hey #datascience nerds: can I just gush for a second on how great the combination of #ZFS and #LMDB is?
I'm working with a 2.1 TB LMDB database of academic citations. I have half a dozen processes hammering away at this at random. But between ZFS's compression and excellent caching and LMDB's clever use of caching I'm barely hitting the disk at all (99% cache hit rate), and it's only using about 15GB memory.
On 1 July, EDRi and 47 civil society organisations sent a joint statement to the Hungarian Council Presidency and a number of member state permanent representatives. We call on the Council and European Parliament to demand that the European Commission withdraw the draft CSA Regulation.
I am all for more diversity in tech!!!I have a blast for kanshi, a tool to handle multiple monitors on wayland

It's so easy to use! 
You have to define a profile for each combination of connected screen you want to support, and configure which resolution / refresh rate / position of each of them (and their position if any).
What's great is that it's per-screen name so if you have multiple desktop with different screen with different quirks (dpi, refresh rate, resolution), you have to declare them all but it will always fit exactly what you wanted.
60 hours left on the "Run Your Own Mail Server" Kickstarter.
Backers get not just RYOMS in their preferred format, but five other Unix-like books as a bonus. $55 in ebooks for just $15, maybe more if we hit another stretch goal--plus assorted losses of authorial dignity. I can't imagine offering a better deal.
