A quick-start guide to podcasting

  • Opensource.com (Posted by bob on Aug 19, 2017 11:22 AM EDT)
  • Story Type: News Story
Presumably the only thing that gives me authority on podcasting is that I have been running my own podcast for almost three years. The Sysadministrivia Podcast often includes not-safe-for-work language—in fact, it conjures images of raucous, uncouth men battling mid-life crises and sitting around a dimly lit poker table, smoking cigars and playing Texas Hold 'Em. We don't play cards, though—we talk about systems administration. read more

  • Story Type: News Story
COBOL is the Rodney Dangerfield of programming languages—it doesn't get any respect. It is routinely denigrated for its verbosity and dismissed as archaic. Yet COBOL is far from a dead language. It processes an estimated 85% of all business transactions, and 5 billion lines of new COBOL code are written every year. read more

Today my colleague almost lost everything that he did over four days of work. Because of an incorrect git command, he dropped the changes he'd saved on stash. After this sad episode, we looked for a way to try to recover his work... and we did it! First a warning: When you are implementing a big feature, split it in small pieces and commit it regularly. It's not a good idea to work for a long time without committing your changes. read more

Open core, open perimeter, and the future of enterprise software

  • Opensource.com (Posted by bob on Aug 17, 2017 7:43 AM EDT)
  • Story Type: News Story
Today, software development is built around APIs. Instead of embedding a vendor's product into their application, developers can call an API to consume services from a vendor.

It is, in many senses, wonderfully non-intimate. read more
