Comment Re:Understanding the risks does not make it safer (Score 1) 106

Stick it on a spare machine, try your mission critical software with test data, see what's different, and what breaks. In any case, you should be asking why you're investigating a non-LTS release for serious stuff, and indeed why you're bothering with Ubuntu at all for serious stuff.

Comment Re:So, they've reached the end of the alphabet (Score 1) 106

Names are less vulnerable to single-char typos. 17.04 is one char (and physically one key) away from 18.04. Also, it is easier to search for things related to your distro using google if you use the name (since google will struggle to grasp the context for each number you use).

Comment Target market likely 'social media pros' (Score 1) 84

There are many who make a tidy income out of social media, and reaching people through Twitter is part of that. I imagine that is a sensible and reasonably sized target market for one level of 'premium'. Heavy users who can spare a few dollars/pounds per month and are basically Twitter junkies would make another sensible target market. But since Twitter surely can't keep losing money every quarter, it's gotta start thinking of this stuff.

How can you get so much wrong in one short post?

Lots of browsers are used on Windows. I use LibreOffice on Windows.

Okay, that is true.

> EMACS vs. vi.

Lots of editors are used with Windows.

BSD is not Linux. It would make as much sense to claim: "MacOS vs. Windows"

> It's the Organized Religion of software, with followers locked in endless battles over which system is The One.

Hardly exclusive to Linux. There is MacOS vs. Windows, Android vs iOS, Firefox vs. Chrome, many competing applications.

> Religion never finding true peace is exactly why Linux has never found the Year of the Desktop.

No. It's all about the apps.

Submission + - Mars rover spots clouds shaped by gravity waves (

sciencehabit writes: NASA’s Curiosity rover has shot more than 500 movies of the clouds above Mars, including the first ground-based view of martian clouds shaped by gravity waves, researchers report. The shots are the best record made so far of a mysterious recurring belt of equatorial clouds known to influence the martian climate. Understanding these clouds will help inform estimates of ground ice depth and perhaps recurring slope lineae, potential flows of salty water on the surface, says John Moores, a planetary scientist at York University in Toronto, Canada, who led the study. “If we wish to understand the water story of Mars’s past,” Moores says, “we first need to [separate out] contributions from the present-day water cycle.”

Submission + - Japanese Company Develops a Solar Cell With Record-Breaking 26%+ Efficiency (

An anonymous reader writes: The silicon-based cells that make up a solar panel have a theoretical efficiency limit of 29 percent, but so far that number has proven elusive. Practical efficiency rates in the low-20-percent range have been considered very good for commercial solar panels. But researchers with Japanese chemical manufacturer Kaneka Corporation have built a solar cell with a photo conversion rate of 26.3 percent, breaking the previous record of 25.6 percent. Although it’s just a 2.7 percent increase in efficiency, improvements in commercially viable solar cell technology are increasingly hard-won. Not only that, but the researchers noted in their paper that after they submitted their article to Nature Energy, they were able to further optimize their solar cell to achieve 26.6 percent efficiency. That result has been recognized by the National Renewable Energy Lab (NREL). In the Nature Energy paper, the researchers described building a 180.4 cm2 cell using high-quality thin-film heterojunction (HJ)—that is, layering silicon within the cell to minimize band gaps where electron states can’t exist. Controlling heterojunctions is a known technique among solar cell builders—Panasonic uses it and will likely incorporate it into cells built for Tesla at the Solar City plant in Buffalo, and Kaneka has its own proprietary heterojunction techniques. For this record-breaking solar cell, the Kaneka researchers also placed low-resistance electrodes toward the rear of the cell, which maximized the number of photons that collected inside the cell from the front. And, as is common on many solar cells, they coated the front of the cell with a layer of amorphous silicon and an anti-reflective layer to protect the cell’s components and collect photons more efficiently.

Comment Re:Try an Antenna - might add Roku & Plex as w (Score 4, Informative) 141

I use an antenna, and also add Rokus, and have Plex on my FreeBSD desktop.

During "Game of Thrones" I sign up for HBO Go - it costs $15 a month.

I also sign up for netflix off and on, and may go with Amazon Prime, since I buy stuff from Amazon anyway.

Works great, I am not missing anything.

Submission + - John Goodenough responds to skeptics of his new lithium-on battery (

Lucas123 writes: John Goodenough, the University of Texas researcher who this week demonstrated new battery cells that are safer and have at least three times as much energy density as today's standard Li-on batteries, responded to skeptics who said the technology described in research published in a peer-reviewed journal, appear to defy the laws of thermodynamics. In an article published Monday by Quartz , various energy experts took exception to Goodenough's claims, even calling them "unbelievable." Goodenough is also co-inventor of the original lithium-ion battery. In an email to Computerworld, Goodenough said "any new discovery invites strong skepticism." In this case, the skeptical scientists wondered how it is possible to strip lithium from the anode and plate it on a cathode current collector to obtain a battery voltage since the voltage is the difference in the chemical potentials (Fermi energies) between the two metallic electrodes,. "The answer is that if the lithium plated on the cathode current collector is thin enough for its reaction with the current collector to have its Fermi energy lowered to that of the current collector, the Fermi energy of the lithium anode is higher than that of the thin lithium plated on the cathode current collector," Goodenough said.

Submission + - GNOME 3.24 Officially Released

prisoninmate writes: GNOME 3.24 just finished its six-month development cycle, and it's now the most advanced stable version of the modern and popular desktop environment used by default in numerous GNU/Linux distributions. It was developed since October 2016 under the GNOME 3.23.x umbrella, during which it received numerous improvements. Prominent new features of the GNOME 3.24 desktop environment include a Night Light functionality that promises to automatically shift the colors of your display to the warmer end of the spectrum after sunset, and a brand-new GNOME Control Center with redesigned Users, Keyboard & Mouse, Online Accounts, Bluetooth, and Printer panels. As for the GNOME apps, we can mention that the Nautilus file manager now lets users browse files as root (system administrator), GNOME Photos imitates Darktable's exposure and blacks adjustment tool, GNOME Music comes with ownCloud integration and lets you edit tags, and GNOME Calendar finally brings the Week view. New apps like GNOME Recipes are also part of this release.
