Since they seem to want to launch from the southern tip of south island I wonder how long they will have to wait for the wind to die down. Two, three years?
But if you have 20 or 30 branches for deployed systems and your fix needs to be imported into most of them then your clean up is viewed as a total PITA because now it is not clear why you made all those changes.
And that means the validation people run through their test book and create maybe 1000 or 2000 bug reports. These bug reports bounce around through the development teams acquiring cruft along the way. When the bug eventually stops bouncing somebody might have a go at fixing it. So they change something and if they can't see the bug anymore they go cvs commit right then and there. At the same time the other 1999 bugs are bouncing around, looking for a home.
At the end of the (as we call it) bug fixing process the original software doesn't exist in its original form. It appears to pass most of the test sbut you would not be advised to lean against it or anything because something else might break.
And neither the summary nor what I had heard meshes with your claim that SA has been turned off and resolutions that are far better than what this new system is supposed to attempt to achieve.
GPS includes a (currently disabled) feature called Selective Availability (SA) that adds intentional, time varying errors of up to 100 meters (328 ft) to the publicly available navigation signals. This was intended to deny an enemy the use of civilian GPS receivers for precision weapon guidance.
Seeing as civilian technologies have been demonstrated to get around the artificial limitation in the accuracy of GPS wouldn't it make more sense for the U.S. military to just allow access to the full precision signal to civilians?
They do. In fact the US military is reliant on consumer grade GPS gear so it is unlikely they would ever turn selective availability back on.
The real distinction now is between meter resolution and centimeter resolution.
I'm struggling to think of a positioning system design that would require GR/SR to work rather than time of flight... I think it would have to be an active transponder system, or some kind of weird gravity wave detector? It would be interesting.
You could use relativistic effects to calculate the motion of a receiver faster than measuring the movement between two positional fixes.
It just turned up here. That said slashcode is a bit flaky now. Occasionally it gives me a front page with the last five or so articles removed. Maybe it gave you a preview for some reason.
Its hard to know when to stop. Windows has been done. This is evidenced by the two most recent versions which don't actually do anything more than XP. It may be the same with gnome. This happens all the time, and not just in software.
There is always FVWM for me. That will never change.
80% percent of the tour looks like stuff in the current gnome. I mean we already have a NetworkManager and you already get a calendar when you click on the clock.
Virtual desktops get more recognition. The UI is more modal and Mac like. So what if their default configuration has just the one panel? Thats how I configure it anyway.
In recent years I have rented two DVDs where the previews were unskippable. Thats annoying. And in the future:
This disk has been licensed for three viewers. To proceed beyond the anti pirating presentation your player must detect three viewers facing the screen with eyes open for the entire 20 minutes.
Ha! One company I deal with for work you have to PGP encrypt your file, ASCII amour the output and strip off the header and footer so you are sending the raw data. Thats the only way to get an attachment into an email for their system. Anything uu or base64 encoded it will crack and if it sees anything at all apart from random data the message gets eaten.
Well probably the ultimate way forward was the hotjava browser, which was just the JDK applet viewer running an applet which could display a web page, with the capability to load new classes to display other content. Unfortunately this idea is more microsofts wet dream than suns wet dream and nobody wants to trust microsoft to that extent.
Simple, kludgy ascii based protocols help to keep the web open.

Umm...

They fire them from Woomera (ie, in the southern hemisphere) all the time.

If we are talking about ray tracing then the clients can share the path for rays from the light sources through reflections off static objects.

From the wiki:
GPS includes a (currently disabled) feature called Selective Availability (SA) that adds intentional, time varying errors of up to 100 meters (328 ft) to the publicly available navigation signals. This was intended to deny an enemy the use of civilian GPS receivers for precision weapon guidance.
As well, it's next to useless if it takes a $15K machine to generate the required images in pseudo-realtime for a single session.
Maybe the rendering cost scales non-linearly.
Maybe if you are trying to render an MMO, a single render farm can do less work in total than all the clients rendering from their own POV.
Someone please explain to me why China is getting treated with kid gloves?
Because if they go down we all go down and they know it.
Thanks. That looks interesting. It is the type of thing we should probably be using in my day job.

A gps time source is only off by a handful of ns. You then want to send that time over NTP and add milliseconds of year?
How else would you distribute your time reference?

I can't spell it either but most of the user interfaces I interact with can.

They are handy in /. signature blocks, which also have an artificial limit on length.
Methinks it is time for somebody to get out and push.

It could be just like video rental places now. Most movies I watch I just rent when I need them. I have the DVDs of a few I want to keep.
