Comment Methane 'super-emitters' on Earth spotted by space (Score 2) 143

From the article at https://www.space.com/emit-instrument-international-space-station-methane-super-emitters:

EMIT has identified more than 50 methane super-emitters in its first few months of operation --- and that's not even its main job.

A powerful eye in the sky is helping scientists spy "super-emitters" of methane, a greenhouse gas about 80 times more potent than carbon dioxide.

That observer is NASA's Earth Surface Mineral Dust Source Investigation instrument, or EMIT for short. EMIT has been mapping the chemical composition of dust throughout Earth's desert regions since being installed on the exterior of the International Space Station (ISS) in July, helping researchers understand how airborne dust affects climate.

That's the main goal of EMIT's mission. But it's making another, less expected contribution to climate studies as well, NASA officials announced on Tuesday (Oct. 25). The instrument is identifying huge plumes of heat-trapping methane gas around the world â" more than 50 of them already, in fact.

Submission + - FCC To Approve 5G Network Despite Military Saying It Will Harm GPS (arstechnica.com)

An anonymous reader writes: The Federal Communications Commission is set to approve a new 5G cellular network despite claims from the Department of Defense that it will interfere with Global Positioning System (GPS) services. FCC Chairman Ajit Pai today asked fellow commissioners to approve an "application to deploy a low-power terrestrial nationwide network in the L-Band that would primarily support 5G and Internet of Things services." The application is from Ligado, formerly known as LightSquared, which for nearly a decade has sought permission to build a wireless network using frequencies near those used for GPS. A previous failure to obtain FCC approval helped push LightSquared into bankruptcy.

The FCC said its draft order would "ensure that adjacent band operations, including GPS, are protected from harmful interference." Pai said the FCC has "compiled an extensive record, which confirms that it is in the public interest to grant Ligado's application while imposing stringent conditions to prevent harmful interference." He continued: "Although I appreciate the concerns that have been raised by certain Executive Branch agencies, it is the Commission's duty to make an independent determination based on sound engineering. And based on the painstaking technical analysis done by our expert staff, I am convinced that the conditions outlined in this draft order would permit Ligado to move forward without causing harmful interference. For example, the draft order would authorize downlink operations at a power level that represents a greater than 99 percent reduction from what Ligado proposed in its 2015 application."

Submission + - My product development (O'Reilly) now a free download! (oreilly.com)

occamboy writes: I'm psyched that O'Reilly's made my book "Prototype to Product" freely available for download, to help teams developing products in response to COVID-19. It's a high-level cross-functional engineering look at how... well, how prototypes are developed into manufacturable products. Covers electronics, software, mechanicals, manufacturing, project management, regulatory, and so forth. Currently at 4.8 stars on Amazon, and only two of the reviews were by friends of mine :).

Hint: Figure 1-1 is all you really need to know, the rest is details.

Submission + - Concerns Over Google Modifying SSL Behavior (vortex.com)

Lauren Weinstein writes: "Google is handling SSL search queries on https://www.google.com/ in a manner significantly different than the standard, expected SSL end-to-end behavior — specifically relating to referer query data. These changes give the potential appearance of favoring sites that buy ads from Google. Regardless of the actual intentions, I do not believe that this appearance is in the best interests of Google in the long run."

Submission + - NASA to test new atomic clock (physorg.com)

edesio writes: "Many satellites and spacecraft require accurate timing signals to ensure the proper operation of scientific instruments. In the case of GPS satellites, accurate timing is essential, otherwise anything relying on GPS signals to navigate could be misdirected.

The third technology demonstration planned by NASA’s Jet Propulsion Laboratory is the Deep Space Atomic Clock. The DSAC team plans to develop a small, low-mass atomic clock based on mercury-ion trap technology and demonstrate it in space."

Submission + - Entry-Level NAS Storage Servers Compared (infoworld.com)

snydeq writes: "InfoWorld's Desmond Fuller provides an in-depth comparison of five entry-level NAS storage servers, including cabinets from Iomega, Netgear, QNAP, Synology, and Thecus. 'With so many use cases and potential buyers, the vendors too often try to be everything to everyone. The result is a class of products that suffers from an identity crisis — so-called business storage solutions that are overloaded with consumer features and missing the ease and simplicity that business users require,' Fuller writes. 'Filled with 10TB or 12TB of raw storage, my test systems ranged in price from $1,699 to $3,799. Despite that gap, they all had a great deal in common, from core storage services to performance. However, I found the richest sets of business features — straightforward setup, easy remote access, plentiful backup options — at the higher end of the scale.'"
Debian

Submission + - Debian 6.0 “Squeeze” frozen (debian-news.net)

edesio writes: From debian-news.net:

"In this very moment, during the ongoing annual Debian Developer
Conference “Debconf10 in New York, Debian’s release managers have
announced a major step in the development cycle of the upcoming stable release Debian 6.0 “Squeeze”: Debian “Squeeze” has now been frozen.

In consequence this means that no more new features will be added and
all work will now be concentrated on polishing Debian “Squeeze” to
achieve the quality Debian stable releases are known for.

The upcoming release will use Linux 2.6.32 as its default kernel
in the installer and on all Linux architectures."
