I see your point. I think there is no getting around the fact that we would receive too little light from the planet. Discarding almost all of the photons coming from it is the best start for a solution, if the best result we could hope is to tell the planet together with all local junk from interstellar objects.

IANAA but I have an impractical idea that might work. Everything outside solar system is either redshifted or blueshifted by a large margin. If we use a very narrow band of spectrum for observation we may observe only stuff move relatively slowly wrt Earth. For example, if we are reasonable sure that any planet in our neighborhood would have some helium in it, just look at around 447.148 nm. Stuff near us move relatively slowly wrt Earth, so helium's absorption bands would be shifted only slightly. If we have a whole sky map at 447.148 nm and one at 447.147, subtracting the former from the latter would give you map of things that are something close by and has helium in it.

I understood you liked Lumina, i was backing you up that it's decent.

Regarding PC-BSD, I'd file a bug report on your install issue and maybe wait until they release a new version against FreeBSD 11.

If you just want the Lumina desktop, perhaps you can install it from a FreeBSD package and switch over to it on your current install? FreeBSD has it in ports/packages.

It's PIN in THE US if it's a debit card (usually) but signature otherwise. Recently went to the UK and non of our cards worked with PIN. Everything was signature and merchants there found it to be a real hassle. They did look at the back of our cards to match it too.

We should have gone chip and pin from the beginning.

The reads seemed a bit faster in the UK than they are here too.

Submission + - Comcast has major outage for Internet subscribers (

An anonymous reader writes: Comcast is currently experiencing a major Internet outage over locations across the US. Many major cities are reporting outages of Internet and VOIP service. Some subscribers are reporting issues with cable television service such as missing channels or pixelation.

Calls to business support indicate there is an outage but Comcast's twitter accounts haven't acknowledged the problem for customers, often claiming it's their modem.

Submission + - Eric Holder says Edward Snowden performed a 'public service'. (

An anonymous reader writes: Former U.S. Attorney General Eric Holder says Edward Snowden performed a "public service" by triggering a debate over surveillance techniques, but still must pay a penalty for illegally leaking a trove of classified intelligence documents.
"We can certainly argue about the way in which Snowden did what he did, but I think that he actually performed a public service by raising the debate that we engaged in and by the changes that we made," Holder told David Axelrod on "The Axe Files," a podcast produced by CNN and the University of Chicago Institute of Politics.

Comment Re:Parts of OS X are already open source (Score 4, Insightful) 268

You're not wrong, but I think open source developers find ways of making code difficult to use as well. For example, the GNOME project seems to hate non Linux operating systems. Many tools are pushing systemd or wayland integration now.

One can argue that since it's open you can re-implement systemd or write a wayland compositor yourself but this is significant work and it's also a moving target. Just because something is open, doesn't mean it's useful.

We all forget that sometimes.

Comment Parts of OS X are already open source (Score 4, Insightful) 268

The Mac OS X kernel and many other system components are already open source and available on Apple's developer site. This has been the case for years.

Similarly, Microsoft has started to open source .NET, ASP.NET and related tech as well as their plan to bring SQL Server to Linux. I think at this point a mix of closed and open source is already happening. Even in the Linux world, some people run Oracle or IBM software that is commercial on linux. This isn't a new thing.
