Norse God Forseti (Forsite)

The God of Justice and Truth. Son of Balder, god of light, and of Nanna, goddess of immaculate purity, Forseti was the wisest, most eloquent, and most gentle of all the gods. When his presence in Asgard became known, the gods awarded him a seat in the council hall, decreed that he should be patron of justice and righteousness, and gave him as abode the radiant palace Glitnir.

Nanna

In Norse mythology, Nanna Nepsdóttir or simply Nanna is a Goddess associated with the god Baldr. In the Prose Edda, written in the 13th century by Snorri Sturluson, Nanna is the wife of Baldr and the couple produced a son, the god Forseti. After Baldr’s death, Nanna dies of grief. Nanna is placed on Baldr’s ship with his corpse and the two are set aflame and pushed out to sea. In Hel, Baldr and Nanna are united again.

Matt Schallert: My Summer at Tumblr

This summer I had the amazing opportunity to work as an Engineering
Intern at Tumblr. Having done two previous internships I thought I
knew what to expect, but Tumblr was a whole new awesome experience
that far exceeded any of my expectations.

The team I worked on is called the SRE Systems team. SRE stands for
Site Reliability Engineering, and is generally responsible for making
sure Tumblr is always up and running at peak performance. At Tumblr,
SRE is divided into three areas with the Systems team overseeing
Tumblr’s infrastructure and the tools that drive it.

Since the SRE team has to make sure that everything is always working
as it should be, the task of monitoring Tumblr’s various systems is an
important one. Anything that’s involved in making the site work needs
to be monitored, whether that’s making sure a server is running all
the processes it should be or checking that the third-party APIs used
by the site are working correctly.

At Tumblr a tool called Icinga is used for monitoring. However just
having Icinga installed isn’t that useful unless it’s properly
configured to monitor what you want it to. The problem of generating
those configurations is what I got to work on for the first part of my
summer. While generating some config files may sound straightforward,
it turns out to be more complicated in practice and was a fun
challenge to work on. The service I created also offered performance
and reliability improvements over the previous tool used for the task,
and getting to see those improvements take effect was really
rewarding.

For the rest of my summer I got to work on planning the migration to
Icinga 2, which is a ground-up rewrite of the original version
(written back in the early 2000’s) and offers a lot of improvements.
Icinga 2 is going to allow Tumblr to have much better insight into the
health of its infrastructure, and if nothing else will save engineers
a lot of headache from clicking around a web interface created over 10
years ago!

Overall my summer at Tumblr was an absolutely incredible experience.
There’s something really powerful about being a part of a company
where everyone is passionate about the same mission of helping
creators make their best content and get it out to the world. And as I
sit in the library back at CMU working my way through problem sets and
class projects, there’s no place I’d rather be than back at the office
with “Fuck Yeah!” doormats and a never-ending supply of cold brew
coffee.
