Today is an #Erlang kind of day. :)

BTW earlier this week I started a new position at +Referential Labs​ as Chief Heretic. :)

The role was literally made for me. At +Referential Labs​ I hope to bring methods and research from academia in declarative/functional programming, formal methods, verification, distributed systems and related fields to applications in the systems, infrastructure, and active telemetry space.

Initially I will be working with some amazing people on Scala and/or Haskell projects in the data analytics space.

Follow us on Twitter @referentiallabs: https://twitter.com/referentiallabs

Cheers and happy reasoning! :)

I am really happy to hear about this opportunity. I hope to see more posts about what we can learn from other fields and apply that knowledge to change the world of operations.

A post on the functional API design choices that impact the ability to equationally reason about your code in functional programming languages:

Paper on the Linux Scheduler...

"Our recent experience with the Linux scheduler revealed that the pressure to work around the challenging properties of modern hardware, such as non-uniform memory access latencies (NUMA), high costs of cache coherency and synchronization, and diverging CPU and memory latencies, resulted in a scheduler with an incredibly complex implementation. As a result, the very basic function of the scheduler, which is to make sure that runnable threads use idle cores, fell through the cracks."

A decade of wasted cores :)

Yesterday I had the opportunity to talk at #PhillyETE about deploying using NixOS at Lookout. Below are my slides. Thanks!

#NixOS
Managing configurations for different kinds of nodes and cloud resources in a microservice architecture can be an operational nightmare, especially if not mana…

Absolutely. Also you will not get into trouble because MySQL 5.5 couldn't build on your version of OS X but that is what is used in production and the one time you do anything DB related there is a diff between 5.5 and 5.6 (your local version). Scaling the team for new devs is critical as well as keeping existing dev's envs up to speed (upgrades happen in infrastructure that may not be reflected in local dev envs of more tenured devs on the team too). It works both ways.

Excerpt:

"I teach her to draw strong professional boundaries and then to enforce them, not because she should have to, but because nobody else will. I insist that she must document everything, because someday he will paint this as a two-way emotional exchange. I wearily advise her to stick it out in science, but only because I cannot promise that other fields aren’t worse. And I hope that this is enough to make him stop. But it never, never stops."

Rest of Barcelona day 2.

+Ben Smith​ note that in the Gothic neighborhood (tourist area) there was quite a lot of graffiti. One photo here shows a man painting over the graffiti with black paint. So some does get covered up.

Last week I went to Toronto with my coworker +Ben Smith to work on a exciting new analytics project with our security researchers in the Toronto office.

In addition to working on Cassandra, Elasticsearch, Titan, and Spark infrastructure configurations, we also got to see some interesting street art and tried some great dark beers.

Thanks Toronto for having us. Much fun was had.

"When I think about getting rid of grades, I think of happier students, with whom I have more open, democratic relationships. I think about being forced to pay more attention to the quiet ones, since I’ll have to write something truthful about them, too. I’ve begun to wonder if a world without grades may be one of those states of affairs (like open marriages, bicycle lanes and single-payer health care) that Americans resist precisely because they seem too good, suspiciously good. Nothing worth doing is supposed to come easy."
