Adrian’s recipe for gluten and dairy free boozy fruit cake

Adrian Cockcroft

This is a synthesis of several recipes that I’ve modified over the years. I usually make a cake for the holidays. Growing up my mother made what she called a Dundee Cake, a round fruit cake with almonds on top. She would make it a month before, and soak brandy into it. My version avoids wheat and dairy, I use honey rather than sugar and I soak the fruit in spirits before I make it, then it’s good to eat a few days later.

Percona

One of the routine operations when administering PostgreSQL is periodic updates to the database system’s architecture. PostgreSQL does a good job of allowing one to update a schema, add types, functions, triggers, or alter a table by adding and removing columns and updating column data types, etc., in a reliable manner. However, there is no built-in mechanism to help identify the differences, let alone generate the necessary SQL, to accomplish updates in an easy manner from the development

Dashboard Story: How We Created PMM Dashboard for Highload

Let’s say you have highload instances. How do you monitor them? There are a lot of servers with 100, 200… 500+ nodes. How can we collect, check, and analyze metrics from all these servers? How can we understand what and where something happened? Scroll, scroll, scroll… down? That was the task that we faced at Percona and successfully resolved.

A MyRocks Use Case

Percona

I wrote this post on MyRocks because I believe it is the most interesting new MySQL storage engine to have appeared over the last few years. Although MyRocks is very efficient for writes, I chose a more generic workload that will provide a different MyRocks use case. The use case is the TPC-C benchmark but executed not on a high-end server but on a lower-spec virtual machine that is I/O limited like for example, with AWS EBS volumes.

Fast memcpy, A System Design

ACM Sigarch

When I worked at Google, fleet-wide profiling revealed that 25-35% of all CPU time was spent just moving bytes around: memcpy, strcmp, copying between user and kernel buffers in network and disk I/O, hidden copy-on-write in soft page faults, checksumming, compressing, decrypting, assembling/disassembling packets and HTML pages, etc. If data movement were faster, more work could be done on the same processors.

Alex Russell

TL;DR : To serve users at the 75 th percentile ( P75 ) of devices and networks, we can now afford ~150KiB of HTML/CSS/fonts and ~300-350KiB of JavaScript (gzipped). This is a slight improvement on last year's budgets , thanks to device and network improvements.

PostgreSQL Role Inheritance at a Glance

Percona

PostgreSQL manages database access permissions using the concept of roles. A role can be either a database user or a group of database users, depending on how the role is set up. Roles can own the database objects and assign privileges on those objects to other roles to control who has access to which objects. Furthermore, it is possible to grant membership in a role to another role, thus allowing the member role to use privileges assigned to another role.
