Comment It's not just audio triangulation (Score 1) 220

The sound triangulated was in cryogenic liquid oxygen at 50 PSI. The speed of sound in that is approximately 1 kilometer per second.This paper is about calculating the exact speed. Elon talked in the conference about reading telemetry with millisecond accuracy. But this would yield only 1 meter resolution.

Submission + - California Legislation May Allow FIrst Responders to Shoot Down Drones

Required Snark writes: During the recent North Fire that burned vehicles on I-15 in California, firefighters had to suspend aerial operations because of the presence of drone aircraft according to CNN

Five such "unmanned aircraft systems" prevented California firefighters from dispatching helicopters with water buckets for up to 20 minutes over a wildfire that roared Friday onto a Los Angeles area freeway that leads to Las Vegas.

Helicopters couldn't drop water because five drones hovered over the blaze, creating hazards in smoky winds for a deadly midair disaster, officials said.

In response, legislation has been introduced that would allow first responders to disable drones in emergency situations. A second bill would allow jail time and fines for drone users that interfere with firefighting efforts.

Senate Bill 168, introduced by Gatto and Sen. Ted Gaines, R-El Dorado, would grant “immunity to any emergency responder who damages an unmanned aircraft in the course of firefighting, air ambulance, or search-and-rescue operations.”

Los Angeles County fire Inspector David Dantic declined to comment on the specific legislation, but said his agency’s aircraft cannot operate safely if a drone is in the same airspace.

Gatto and Gaines also teamed up on companion legislation: SB 167, which would increase fines and introduce the possibility of jail time for drone use that interferes with firefighting efforts.

Submission + - Europe's top court to decide if Uber is tech firm or taxi company

An anonymous reader writes: A Spanish judge has requested that the European Court of Justice determine whether or not Uber is a generic "digital service," as it claims, or a "mere transport activity." If the court rules that Uber is a transportation firm the company may have to follow the same licensing and safety rules as taxis and other hired vehicles. "Today's news means that the European Court of Justice will now determine if the national rules currently being applied to digital services like Uber are legal and appropriate under European law," said Mark MacGann, Uber's Head of Public Policy for EMEA, on a conference call with journalists.

Roger,

This is great. It does look like a 1:1 mapping to what we expect autoconf to do, except neater and maintainable.

The only problem with selling this to GNU folks is that it would make CMake a prerequisite to everything. But I think it's worth it. And then there's inertia. And the language isn't as pretty as we'd like.

Can you see any other possible objections?

Thanks

the Emacs vs VI war is over (Emacs won)

Nope. B-)

When I got my first UNIX box, back in the '80s, it had two megabytes and did NOT have demand paging, which would have allowe a larger virtual image to run. That was too small to compile emacs. (The joke at the time was that the name was really an acronym for Eight Megabytes And Constantly Swapping. B-) )

So I learned VI. Then I used it VERY heavily for years, on the original conferencing system whose software was later ported to The Well. After that a number of editing idioms were "wired into" my hindbrain and I could do the things I wanted to do with text very efficiently with vi.

As machines improved I tried emacs several times. Each time I found that the stuff I depended on took about 1.5 to 3 times as many keystrokes. This was too much of a penalty to pay for the handful of features it offered.

At one point I considered going to it but running in a vi emulator mode and gradually migrating to native idioms. But I discovered that, kitchen sink that it was, it had TWO vi emulator modes, each with distinct deviations from vi (alias "bug sets"). With one vi emulator, even with substantial shortcomings, I might still have made the shift. With two there was no easy way to chose, so I didn't bother.

Now I'm using vim, which is close enough. One of my regular colleagues is an emaxian rather than a vithian and we get along just fine. B-)

Also: It's not clear to me which group should be handling this. It seems to be a conflict between how two projects downstream of the compiler itself are handling a global namespace.

I'd only expect the compiler guys to fix it if they decided the downstream stuff was a problem and pulled part of it into their own stuff to settle the matter.

Wouldn't it be easier to check your bugzilla ticket?

There were already several tickets out on it (and flames from the maintainers about duplicates) so I didn't file another. None of them seemed to indicate that anyone, let alone the core compiler crew, were intending to do anything abut it.

I was hoping someone more actively engaged in either reporting or dealing with the issue might happen to be participating here and care to chime in. B-)

Meanwhile, others should know that there IS (or, we can hope, WAS) an issue before they make plans to try to use the toolset for a new project.
