See the original posting on DZone Python

I think some of us are getting it wrong when it comes to self-organization.

Self-organization doesn’t mean that the team doesn’t have managers or that they get to decide what problems to solve or what product to build.

Self-organization doesn’t mean that the team doesn’t have any tooling constraints, or architectural constraints, or budget constraints, or timing…

Samsung’s new ATIV Book 9 was announced last year at CES, and now it has a release date. The all-aluminum ultrabook, which looks like Samsung’s strongest answer to the MacBook Air yet, will be available beginning March 1st. At  0.46-inches thick and 2.09 pounds, it’s the lightest laptop in the Book 9 line. Visually, it’s similar to other offerings in Samsung’s recent lineup, and features Intel’s Broadwell Core M processor. Samsung is also paying more attention to audio this time: the laptop features a built-in Wolfson lossless audio player and native FLAC support.

See the original posting on The Verge

After decades of hints and rumors, the original Catwoman, Selina Kyle, finally came out of the closet as bisexual this week. In Catwoman #39, Selina is the head of Gotham’s Calabrese crime family, and, on the brink of a mob war, shares a kiss with the woman currently in the Catwoman costume, Eiko Hasigaway, in a moment that promises that have major ramifications for both characters as the storyline progresses. It’s a big moment for the narrative, but most important is that, according to series writer Genevieve Valentine, the confirmation is canon.

In her blog, Valentine writes that, for her, “this wasn’t a revelation so much as a confirmation.” Indeed, Selina Kyle’s relationships outside of the one she shares with Bruce Wayne have…
