Submission+-The Programmers That Want To Get Rid of Software Estimates (medium.com)

An anonymous reader writes: A look inside the #NoEstimates movement, which wants to rid the software world of time estimates for projects. Programmers argue that estimates are wrong too often and a waste of time. Other stakeholders believe they need those estimates to plan and to keep programmers accountable. Is there a middle ground?

Software project estimates are too often wrong, and the more time we throw at making them, the more we steal from the real work of building software. Also: Managers have a habit of treating developers’ back-of-the-envelope estimates as contractual deadlines, then freaking out when they’re missed. And wait, there’s more: Developers, terrified by that prospect, put more and more energy into obsessive trips down estimation rabbit-holes. Estimation becomes a form of “yak-shaving”—a ritual enacted to put off actual work.

Google Pledges Not To Sue Any Open Source Projects Using Their Patents153

sfcrazy writes "Google has announced the Open Patent Non-Assertion (OPN) Pledge. In the pledge Google says that they will not sue any user, distributor, or developer of Open Source software on specified patents, unless first attacked. Under this pledge, Google is starting off with 10 patents relating to MapReduce, a computing model for processing large data sets first developed at Google. Google says that over time they intend to expand the set of Google's patents covered by the pledge to other technologies." This is in addition to the Open Invention Network, and their general work toward reforming the patent system. The patents covered in the OPN will be free to use in Free/Open Source software for the life of the patent, even if Google should transfer ownership to another party. Read the text of the pledge. It appears that interaction with non-copyleft licenses (MIT/BSD/Apache) is a bit weird: if you create a non-free fork it appears you are no longer covered under the pledge.

Submission+-7th Graders Find Large Cave on Mars (cnet.com)

EMB Numbers writes: Cnet news http://news.cnet.com/8301-17938_105-20008507-1.html?part=rss&subj=news&tag=2547-1_3-0-20 reports that "the science class from Evergreen Middle School in Cottonwood, Calif. found the opening while working on a research project with the Mars Space Flight Facility run out of Arizona State University in Tempe." "The students examined more than 200 images of Mars taken with the Thermal Emission Imaging System (Themis), an instrument on NASA's Mars Odyssey orbiter."

The only other similar opening near the volcano was found in 2007, when Glen Cushing, a scientist with the U.S. Geological Survey, published a research paper on the surface anomalies.

The opening is estimated to be 620 feet by 520 feet and the hole to be at least 380 feet deep.
