The Programmers Who Want To Get Rid of Software Estimates

An anonymous reader writes: This article has 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? Quoting: "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.

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."

Why debunked autism treatment fads persist

Science Daily - Thu, 26/02/2015 - 8:46pm
The communication struggles of children with autism spectrum disorder can drive parents and educators to try anything to understand their thoughts, needs and wants. Authors describe a litany of treatments for autism that have been attempted with little or no success over the years, including gluten- and casein-free diets, antifungal interventions, chelation therapy, magnetic shoe inserts, hyperbaric oxygen sessions, weighted vests, bleach enemas, sheep-stem-cell injections and many more.

Social circles: Degree to which urban movement is linked to social activity

Science Daily - Thu, 26/02/2015 - 8:46pm
If you live in a city, you know that a fair amount of your movement around town is social in nature. But how much, exactly? A study uses a new method to infer that around one-fifth of urban movement is strictly social, a finding that holds up consistently in multiple cities.

Malaria transmission linked to mosquitoes' sexual biology

Science Daily - Thu, 26/02/2015 - 8:46pm
Sexual biology may be the key to uncovering why Anopheles mosquitoes are unique in their ability to transmit malaria to humans, according to researchers. "Our study is the first to reveal the evolutionary dynamics between the sexes that are likely responsible for shaping the ability of Anopheles mosquitoes to transmit malaria to humans," said the study's senior author.

Strong connection between violence, mental illness in Guatemala during civil war lessens in postwar period

Science Daily - Thu, 26/02/2015 - 8:45pm

Embrace unknowns, opt for flexibility in environmental policies, experts say

Science Daily - Thu, 26/02/2015 - 8:45pm
We make hundreds, possibly thousands, of decisions each day without having full knowledge of what will happen next. Life is unpredictable, and we move forward the best we can despite not knowing every detail. Likewise, two professors argue that ecosystem managers must learn to make decisions based on an uncertain future.

Facebook's Colonies

Slashdot - Thu, 26/02/2015 - 8:38pm
sarahnaomi writes: Facebook this week released a major report on global internet access, as part of the company's Internet.org campaign, which aims to bring cheap internet to new markets in partnership with seven mobile companies. Facebook says 1.39 billion people used its product in December 2014, and it's natural for the company to try to corral the other four-fifths of the planet. But aside from ideals and growth markets, the report highlights a tension inherent to the question of access: When Facebook sets sail to disconnected markets, what version of the internet will it bring? In its report, Facebook advocates for closing the digital divide as quickly as we can, which is a good thing. But when Facebook argues that, "as use of the internet continues to expand, it will exert a powerful effect on the global economy, particularly in the developing world," it's arguing that any increase in access is inherently good, which isn't necessarily the case.

Who's Afraid of Android Fragmentation?

Slashdot - Thu, 26/02/2015 - 7:55pm
Nerval's Lobster writes: The dreaded term "fragmentation" has been applied to Android more times than anyone can count over the past half-decade. That's part of the reason why game developers often build for iOS before Android, even though Android offers a bigger potential customer base worldwide, and more types of gaming experiences. Fortunately, new sets of tools allow game developers to build for one platform and port their work (fairly) easily to another. "We've done simultaneously because it is such a simple case of swapping out the textures and also hooking up different APIs for scores and achievements," London-based indie developer Tom Vian told Dice. "I've heard that iOS is a better platform to launch on first, but there's no sense for us in waiting when we can spend half a day and get it up and running." So is fragmentation an overhyped roadblock, or is it a genuine problem for developers who work in mobile?

'Ecosystem services' help assess ocean energy development

Science Daily - Thu, 26/02/2015 - 7:49pm
Environmental scientists suggest that the way to fill vast gaps in knowledge about the ecological and socioeconomic impacts of ocean energy development is to consider how the benefits provided by ocean ecosystems change before and after the placement of ocean energy infrastructure.
