  • At the Crossroads of Open Source and Open Standards [Ed: Another Linux Foundation article]
    A new crop of high-value open source software projects stands ready to make a big impact in enterprise production, but structural issues like governance, IPR, and long-term maintenance plague OSS communities at every turn. Meanwhile, facing significant pressures from open source software and the industry groups that support them, standards development organizations are fighting harder than ever to retain members and publish innovative standards. What can these two vastly different philosophies learn from each other, and can they do it in time to ensure they remain relevant for the next 10 years?

Red Hat: PodCTL, Security Embargos at Red Hat and Energy Sector

  • [Podcast] PodCTL #50 – Listener Mailbag Questions
    As the community around PodCTL has grown (~8000 weekly listeners) we’ve constantly asked them to give us feedback on topics to discuss and areas where they want to learn. This week we discussed and answered a number of questions about big data and analytics, application deployments, routing security, and storage deployment models.
  • Security Embargos at Red Hat
    The software security industry uses the term Embargo to describe the period of time that a security flaw is known privately, prior to a deadline, after which time the details become known to the public. There are no concrete rules for handling embargoed security flaws, but Red Hat uses some industry standard guidelines on how we handle them. When an issue is under embargo, Red Hat cannot share information about that issue prior to it becoming public after an agreed upon deadline. It is likely that any software project will have to deal with an embargoed security flaw at some point, and this is often the case for Red Hat.
  • Transforming oil & gas: Exploration and production will reap the rewards
