What would a EvE online Internet look like?
I always viewed this map like a network, it’s a large mesh of systems that connect to each other so that people can get across, with most systems having more than two jump gates. this lead me to think what would happen if you took the idea of the map being a network literally? What would a EvE online internet of systems look like?

For this we need to understand how the real Internet works. The internet is a large collection of ISP’s that are all numerically identified with a standardised and unique ISP number, called an Autonomous System Number or ASN ( or AS for shorter ). These AS’es need a way to exchange routes with each other, since they will own ranges of IP addresses, and need a way to tell other ISPs that their routers can route these IP addresses. For this, the world has settled on Border Gateway Protocol or BGP.

Scala Best Practices - Foreword
I often find myself, both professionaly and otherwise, having to explain bits of Scala to newcomers to the language (but usually not new to programming).

Something that’s becoming increasingly obvious is that Scala developers follow a certain set of unspoken rules without really thinking about them, and never really explain them to beginners. This is not helping Scala’s reputation as a hard to learn language, which is unfortunate - it’s a language I enjoy and wish more people would learn.

This site is meant to address that, by listing and explaining all these rules I wish someone’d told me about when I was learning the language.

Comments, suggestions, … are welcome! I’m clearly not the best Scala developer out there and might have gotten things wrong, or right for the wrong reasons. If you see areas that could be improved on, feel free to open an issue!

Squarespace/pgbedrock: Manage a Postgres cluster's roles, role memberships, schema ownership, and privileges
pgbedrock is an application for managing the roles, memberships, ownerships, and most importantly the permissions for tables, sequences, and schemas in a Postgres database.

Given the parameters to connect to a Postgres database (i.e. host, port, etc.) and a YAML file (a "spec") representing the desired database configuration, pgbedrock makes sure that the configuration of that database matches the spec. If there are differences, it will alter the database to make it match the spec.

It can be run as a docker container (via docker run quay.io/squarespace/pgbedrock) or as a local command-line utility (via pip install pgbedrock).

λ Tony's blog λ - scala.Option Cheat Sheet
Many people who are coming in to Scala first encounter the Option type, which may be thought of (among other things) as a type-safe null. They also encounter pattern matching as both a new and (relatively) powerful concept, but also one that is easy to understand. This leads to quite a lot of use of pattern matching and often excessively so in what I have observed.

Deploying EFF's Certbot in AWS Lambda
This post describes the steps needed to deploy Certbot (a well-maintained LetsEncrypt/ACME client) inside AWS Lambda. The setup used below is now powering 100% automated TLS certificate renewals for this website - the lambda runs once a day and if there’s less than 30 days remaining on my existing cert it will provision a new one and import it to be served by my CDN.

kelseyhightower/kubernetes-the-hard-way: Bootstrap Kubernetes the hard way on Google Cloud Platform. No scripts.
This tutorial walks you through setting up Kubernetes the hard way. This guide is not for people looking for a fully automated command to bring up a Kubernetes cluster. If that's you then check out Google Kubernetes Engine, or the Getting Started Guides.

Kubernetes The Hard Way is optimized for learning, which means taking the long route to ensure you understand each task required to bootstrap a Kubernetes cluster.

Istio / Consuming External Web Services
In many cases, not all the parts of a microservices-based application reside in a service mesh. Sometimes, the microservices-based applications use functionality provided by legacy systems that reside outside the mesh. We may want to migrate these systems to the service mesh gradually. Until these systems are migrated, they must be accessed by the applications inside the mesh. In other cases, the applications use web services provided by external organizations, often over the World Wide Web.

firstlookmedia/gpgsync: GPG Sync is designed to let users always have up-to-date public keys for other members of their organization
GPG Sync is designed to let users always have up-to-date OpenPGP public keys for other members of their organization.

If you're part of an organization that uses GPG internally you might notice that it doesn't scale well. New people join and create new keys and existing people revoke their old keys and transition to new ones. It quickly becomes unwieldy to ensure that everyone has a copy of everyone else's current key, and that old revoked keys get refreshed to prevent users from accidentally using them.

GPG Sync solves this problem by offloading the complexity of GPG to a single trusted person in your organization. As a member of an organization, you install GPG Sync on your computer, configure it with a few settings, and then you forget about it. GPG Sync takes care of everything else.

RevK®'s rants: Unicode Dicks
One of the things that has always slightly amused and puzzled me is that unicode lacks a "cock" glyph. I mean, it seems to have characters and symbols from modern and historic cultures and forms of writing, and surely cave men have been drawing dicks on cave walls for tens of thousands of years, so why is this missing?

Postgres Distributed Key Generation
This SQL creates a Postgres function to generate sequential, numeric, unique IDs in a consistent format across services. Useful for database sharding or microservices.

Draws heavily on Instagram's ID generator, via Rob Conery, with minor modifications.

The main changes are that the unique number resolution is per-second rather than per-millisecond. This is to reduce key size below 2^53^-1 so that generated IDs that are under Javascripts Number.MAX_SAFE_INTEGER limit . This is important if you're using these on a Node.js server (e.g. our use case is an Express API using Hashids).

Max IDs are in the order of 51 bits, broken down as follows:

31 bits for the timestamp difference
10 bits for a unique service ID (eg ID of the service/shard)
10 bits for a global sequence ID (modulo 1024 — meaning a maximum of 1024 unique records per second)
