Like US car companies, it is very hard to admit when the fat years are over. Give them time; I suspect they will come around a bit.

Like anything in the US, all the big players wants to keep status quo. In many ways I experience the US as being hopelessly stuck in the 70'ties...
Granted I've only lived here for a little more than a year now, nor was alive in the 70'ties :)

Submission + - Japan to land unmanned lunar probe in 2018 (astrowatch.net)

Taco Cowboy writes: The Japan Aerospace Exploration Agency (JAXA) is planning to attempt Japan’s first lunar landing in fiscal 2018, sources close to the project said Sunday. JAXA has said it will use unmanned probes to study the possible use of materials on the moon as well as its environment, which could pave the way for future manned missions. JAXA is expected to brief a government panel on the project with the aim of securing funding for mission preparations from the budget for fiscal 2016, which begins next April, the sources said

The lunar probe is likely to be launched on an Epsilon advanced rocket, the sources said

The SLIM mission is aimed at establishing a method for pinpoint landings that would make it possible to approach a target area with a level of accuracy ranging in the hundreds of meters

Submission + - Hubble turns 25 (hubble25th.org)

Taco Cowboy writes: The Hubble Telescope was launched on April 24, 1990, aboard the Space Shuttle Discovery from Kennedy Space Center, Florida

Currently it is flying about 340 miles over the Earth and circling us every 97 minutes

While the telescope itself is not really much to look at, that silver bucket is pure gold for astronomers

Scientists have used that vantage point to make ground-breaking observations about planets, stars, galaxies and to reveal parts of our universe we didn't know existed. The telescope has made more than 1 million observations and astronomers have used Hubble data in more than 12,700 scientific papers, "making it one of the most productive scientific instruments ever built," according to NASA

The truly spectacular images of the cosmo have also led to a scientific bounty that has far exceeded Hubble’s original goals: measuring how fast the universe is expanding; figuring out how galaxies evolve; and studying the gas that lies between galaxies

NASA aims to keep Hubble operating through at least 2020 so that it can overlap with its successor. The James Webb Space Telescope is due to launch in October 2018 and begin observations in mid-2019

The institute is reviewing scientists’ proposals for telescope time and mulling if some projects merit special attention as Hubble nears its end. Typically, the program receives about five requests for every hour of available telescope time

“There’s clearly there’s no lack of things to do with this observatory in its remaining years. The question is what do we do?” Sembach said at a recent American Astronomical Society meeting in Seattle

Submission + - Rosetta spacecraft witnessed and recorded a 'Comet Fart' (discovery.com) 1

An anonymous reader writes: On March 12, the Rosetta spacecraft was imaging Comet 67P/Churyumov-Gerasimenko from a distance of 75 kilometers (46 miles) and by pure chance it spotted an eruption of dusty material from the shaded nucleus

Long-duration spacecraft are essential if we are to fully understand the evolution of a comet as it gradually heats up during its approach to the sun. And it just so happens that Rosetta is always in orbit around 67P’s nucleus, ready to spot any transient event that could erupt at any time on the surface

This latest event focuses on the comet’s shaded underside. It is assumed that some sunlight slowly heated an outcrop, providing enough energy to sublimate subsurface ices, ejecting vapor and dust as a jet. The transient jet was imaged and measured by Rosetta’s scientific imaging system OSIRIS

There is also the possibility that a wave of heating passed through the icy material, eventually producing a more explosive jet event

Comment Actually it should be farthest (Score 2) 94

Furthest-most? When "furthest" is just not far enough?

Technically it should actually be "farthest" since it refers to a physical distance whereas "furthest" means most distant in a figurative sense. For example you say "furthest from the truth" not "farthest from the truth" but "Cape Spear is the farthest east you can go in Canada" not "furthest east". So to summarize: "furthest-most" should not have a hyphen, should not have the 'most' added since it is redundant and finally should actually be "farthest" since it refers to a physical distance.

As for the origin of the "cold spot" I understood that it was completely statistically consistent with quantum fluctuations in the early universe. So how about we rule out that explanation first before coming up with multiple universes or other crazy stuff.

IPSec is perfectly usable.

Telebit demonstrated transparent routing (ie: total invisibility of internal networks without loss of connectivity) in 1996.

IPv6 has a vastly simpler header, which means a vastly simpler stack. This means fewer defects, greater robustness and easier testing. It also means a much smaller stack, lower latency and fewer corner cases.

IPv6 is secure by design. IPv4 isn't secure and there is nothing you can design to make it so.

IPv6 would help both enormously. Lower latency on routing means faster responses.

IP Mobility means users can move between ISPs without posts breaking, losing responses to queries, losing hangout or other chat service connections, or having to continually re-authenticate.

Autoconfiguration means both can add servers just by switching the new machines on.

Because IPv4 has no native security, it's vulnerable to a much wider range of attacks and there's nothing the vendors can do about them.

Comment Re: DNS without DHCP (Score 4, Informative) 390

Anycast tells you what services are on what IP. There are other service discovery protocols, but anycast was designed specifically for IPv6 bootstrapping. It's very simple. Multicast out a request for who runs a service, the machine with the service unicasts back that it does.

Dynamic DNS lets you tell the DNS server who lives at what IP.

IPv6 used to have other features - being able to move from one network to another without dropping a connection (and sometimes without dropping a packet), for example. Extended headers were actually used to add features to the protocol on-the-fly. Packet fragmentation was eliminated by having per-connection MTUs. All routing was hierarchical, requiring routers to examine at most three bytes. Encryption was mandated, ad-hoc unless otherwise specified. Between the ISPs, the NAT-is-all-you-need lobbyists and the NSA, most of the neat stuff got ripped out.

IPv6 still does far, far more than just add addresses and simplify routing (reducing latency and reducing the memory requirements of routers), but it has been watered down repeatedly by people with an active interest in everyone else being able to do less than them.

I say roll back the protocol definition to where the neat stuff existed and let the security agencies stew.
