Big bang pushed back two billion years

Our universe may be 15% larger and older than we thought, according to new measurements of the distance to a nearby galaxy.

Researchers led by Alceste Bonanos at the Carnegie Institution of Washington, US, used data from telescopes including the 10-metre Keck-II telescope in Hawaii, US, to measure the distance to a pair of stars in the Triangulum Galaxy.

The team used light, velocity, and temperature measurements to calculate the true luminosity of the two stars, which eclipse one another every five days. By comparing this intrinsic luminosity to their observed brightness, the team calculated that the galaxy lies 3.14 million light years away from us. Surprisingly, this is about half a million light years farther than previously thought.

Full Story.

I thought so...

I noticed that I needed a larger waist in the pants I just bought. Now I know why!

Matthias Klose has provided an update concerning plans for having GCC 6 become the default compiler of Debian 9.0 "Stretch." Everything still is on target for making GCC 6 the default for Stretch; GCC6 is currently available in Debian Testing, build failures are being worked through in the testing/unstable world, and there will be some bug squashing parties this summer for trying to get GCC 6 into shape.

Linux Kernel 4.6.3 Has Multiple Networking Improvements, Better SPARC Support

Today, June 24, 2016, renowned Linux kernel developer Greg Kroah-Hartman has announced the general availability of the third maintenance release for the Linux 4.6 kernel series. Linux kernel 4.6.3 is here two weeks after the release of the second maintenance update in the series, Linux kernel 4.6.2, to change a total of 88 files, with 1302 insertions and 967 deletions. Unfortunately, very few GNU/Linux distributions have adopted the Linux 4.6 series, despite the fact that Greg Kroah-Hartman urged everyone to move to this most advanced kernel branch as soon as possible from Linux 4.5, which reached end of life.

Leftovers: Gaming

  • Open Source Initiative, Breathing Games Collaborate By Creating Open Source Gaming Software
    The Open Source Initiative (OSI) announced that Breathing Games an international community working to improve the quality of health care and life expectancy for people with respiratory disease through therapeutic, science-based-and fun-games, had become an affiliate member. With one person in five now affected by chronic respiratory diseases-asthma, obstructive disease, and cystic fibrosis among many others-creating effective and engaging patient therapies is an increasingly challenging public health care issue. Patients, especially children, often perceive effective, traditional breathing exercises as boring and tedious. Poor patient compliance results in additional hospitalizations and increased costs. Research shows health-based gaming delivers promising results in positively changing behaviors and influencing health care practices.
