Philip Reames is a experienced software engineer with technical lead and management experience.

In this short video, Philip talks about Falcon, a new Just-in-time compiler (JIT) for the Zing VM. The goal is to replace C2. It is built around LLVM. 

Falcon features:

  • Azul’s new “Falcon” Just-in-Time (JIT) compiler is a new, highly optimized runtime compiler for Azul’s Zing runtime for Java (JVM)
  • Falcon is based on LLVM, the compiler infrastructure project backed by dozens of companies and hundreds of contributors advancing the latest capabilities in modern compiler technology
  • Falcon delivers substantial performance gains over Java’s legacy “C2” JIT compiler
  • Zing with Falcon achieves better application SLA metrics, reduces operating costs, and results in an improved customer experience

Google decided to close the social network Google+ not in August 2019, but in April. The reason was another vulnerability in the API, due to which it was possible to obtain private information of 52.5 million accounts. The company plans to close the social network API until mid-March 2019.

By December 10, 2018, the following error information was published:

  • Third-party applications requesting access to profile data, because of the bug in the API, received permission to view information, even if it is hidden by privacy settings;
  • the names of users, their email addresses, information about occupation, age and other confidential information were at risk;
  • passwords, financial data and national identification numbers have not been compromised;
  • the company has no evidence that anyone has exploited the vulnerability;
  • the error was fixed within 6 days: from November 7 to November 13, 2018.
  • Google said it sends notifications to all users affected by the bug.

The previous data leak of Google+ users occurred in October 2018. Then about 500 thousand accounts were compromised. The attackers could get the names, email addresses, age, gender and occupation of users.
