What is Protocol Buffers?

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. You can even update your data structure without breaking deployed programs that are compiled against the "old" format.

Why not just use XML?

Protocol buffers have many advantages over XML for serializing structured data. Protocol buffers:

  • are simpler
  • are 3 to 10 times smaller
  • are 20 to 100 times faster
  • are less ambiguous
  • generate data access classes that are easier to use programmatically

24 April 2019   144

The release of Node.js 12.0.0, a platform for executing network applications in JavaScript, is available. Node.js 12.0 refers to branches with a long period of support, but this status will be assigned only in October, after stabilization. Updates for LTS branches are issued for 3 years. Support for the last LTS branch of Node.js 10.0 will last until April 2021, and the year before last LTS-branch 8.0 until January 2020. Support for the intermediate branch Node.js 11.0 will be discontinued in June 2019. The lifetime of the LTS branch 6.0 will end on April 30.

These are some of the large list of updates and new staff:

  • V8 engine was updated to version 7.4 with support for asynchronous stack traces, increasing await performance, parsing JavaScript and calls when the actual and declared number of arguments does not match;
  • TLS 1.3 is now supported in the tls module and TLS 1.0 / 1.1 is shutdown by default;
  • Enhancing protection and checks on the size of allocated memory in the Buffer class;
