GitHub has been at work for the last year to develop a new load balancer, the GitHub Load Balancer (GLB), aimed to be able to scale to billions of connections per day running on commodity hardware. GitHub engineers Joe Williams and Theo Julienne explain how GLB was designed.
Day 1 of JavaOne 2016 topics: learning about Java 8&9 features, Docker for Java developers, and development tools for Java EE 8. InfoQ highlights a few of the day's interesting sessions.
Continuous deployment results in a higher sense of responsibility and better quality of deployments, argues Paul de Raaij, technical pathfinder at Coolblue. Coding standards prevent your code base from becoming a mess, automated inspections are great for tedious and boring checks, and manual checks are great for checking if the logic or use of code actually makes sense.
Shape Security has open sourced a new schemaless binary serialization format called SuperPack.
Google has started updating certain devices to the latest Android 7.0, dubbed Nougat.

At QCon New York 2016, Etsy software engineer Stefanie Schirmer told how her company successfully transitioned to an API-first architecture that supports multiple devices, addresses server-side performance problems, and was quickly adopted by development teams.
Stefan Thies, DevOps Evangelist at Sematext, in a recent post discusses ten important container monitoring metrics and their implications on operating Docker containers, specifically when running many containers per host. Combined in a single correlated view these metrics provide a starting point for monitoring Docker-based environments.
In his presentation "Understanding Hardware Transactional Memory" at QCon New York 2016, Gil Tene introduces hardware transactional memory (HTM). Whereas the concept of HTM is not new, it is now finally available in commodity hardware. The purpose of HTM is to be able to write to multiple addresses in memory in an atomical way so that there cannot be inconsistencies in cooperation other threads.
Although the definition of system programming is fuzzy, it can be described as having to think at the bit, byte, instruction or CPU cycle level. Systems programming also implies demanding performance and reliability requirements. Joe Duffy, engineering director at Microsoft, presented strategies for system programming in C# at QCon New York. He also discusses pitfalls and how to mitigate them.
Windows Management Instrumentation (WMI) is a primary source of data when monitoring Windows systems. Given that the performance counters available vary from machine to machine, a tool is needed to list all counters available. The WMI type provider is one possible option to explore WMI performance counters.
While the last two versions of SQL Server focused on improving performance by offering new features, SQL Server 2016 looks inwards towards improving existing functionality.
Log4j, the popular logging library for Java, will include a number of configuration options that allows it to run in a completely garbage-free manner. The release follows previous attempts to improve the performance of logging libraries, and has been positively received by the industry. Further changes to increase the number of scenarios in which log4j can run garbage-free are expected.
