Certified··on xDedic – the shady world of hacked servers for sale
Certain FOX episodes have shown up on file sharing networks over the past years with trailers for other FOX shows preceding the actual content. You don't think networks are already promoting their tv shows directly to the file sharing demographic?
Certified··on Samsung Demos Its First BGA SSD: 1500 MB/s Read Speed and Tiny Package
I have not knowingly seen this used in the wild but it looks intriguing. I've seen a lot of conformal coatings used to increase shock resistance but from my experience that is only half the battle. The thermal expansion and contraction can be the real slow silent killer. The caveat being that I was dealing with devices rated (and used) from -30°C to 85°C.

I was referring to a seismic acquisition node used in geophysical exploration. Here is an example of a seismic node made by Sercel, one of the largest players in that market: http://www.sercel.com/products/Pages/unite.aspx

I used to repair seismic nodes as part of my job. BGAs had the highest failure rate in high shock and temperature cycling environments by far. I find it worrying that so many chips are being designed with BGA. All it takes is one ball disconnect and you have a useless device without an expensive solder reflow. It seems like a really good way to design a device to have to be replaced after 5-10 years...

>It was an old plane. It was marginal economically. It had a fatal accident. And then, just as it was returning to service, the travel slump after 9/11 happened.

I agree that all those are the primary retirement factors but I did not want to bring them up as they where being discussed elsewhere in the comments.

I'm interested to see that people where complaining about the potential of Concorde stratospheric pollution all the way back in 1972[1]. Maybe it was not so much a reason for retirement but one of the many reasons the concorde received such a poor public reception in the 70s. I think Boom has some serious hurdles ahead of them in this regard. Environmental regulations have done nothing but grow since the 1970s and many countries where outright banning the concorde from their airspace then.

Maybe I am misinformed but I was under the impression part of the reason concorde was retired is because at those speeds you tear up the ozone.

"From their particle measurements, the authors of the Science study calculate that a future possible fleet of 500 supersonic passenger aircraft will increase the surface area of particles in the atmosphere by an amount similar to that following small volcanic eruptions. In mid-latitude regions, such emissions have the possibility of increasing ozone loss above that expected for nitrogen oxide emissions alone. The increase in the number of particles may also affect the ozone-related processes occurring on wintertime polar stratospheric clouds (PSCs) in the polar regions."

Certified··on Unexpected evidence of a new particle at LHC
Ah ha! I appreciate you pointing this out. I read the sentence at least ten times trying to make sense of it and still failed to make that connection.

It still leaves me wondering what experiment at the LHC has attempted to reveal extra dimensions of, and collapse matter into a black hole. I have not been able to find any LHC experiments with this set as a goal, but I would love to be shown otherwise.

Certified··on Unexpected evidence of a new particle at LHC
I got to the second sentence before getting frustrated with the integrity of an article by Nature:

"They have tried to recreate dark matter, reveal extra dimensions of and collapse matter into microscopic black holes."

The missing word was slightly irksome. I find the claim that anyone has intentionally tried to create microscopic black holes bombastic.

CERN's own site:

"According to the well-established properties of gravity, described by Einstein’s relativity, it is impossible for microscopic black holes to be produced at the LHC. There are, however, some speculative theories that predict the production of such particles at the LHC. All these theories predict that these particles would disintegrate immediately. Black holes, therefore, would have no time to start accreting matter and to cause macroscopic effects." - http://press.web.cern.ch/backgrounders/safety-lhc

They have certainly looked into it for safety sake but if CERN's intent was to create microscopic black holes, I suspect it would be a very different machine.

Certified··on Scientists track down the source of mysterious radio bursts
It has been suggested that some if not most elliptical galaxies are the result of two similarly sized spiral galaxies colliding: http://spacetelescope.org/images/potw1148a/

The most energetic event I can think of would be two galactic core sized black holes colliding. Has this been ruled out already as a possible cause of FRBs?

Certified··on Secretive X-37B Military Space Plane Could Land in California Tuesday
TL;DR : I think the X-37 is nothing more spectacular than an upgradable spy satellite that can change it's orbit of inclination giving it the ability to spy on any part of the globe as quickly as possible.

Although the X-37B's mission is a closely guarded secret, many facts are public knowledge. I compiled a quick timeline a while back and seeing as it is in the news again, I am reviving it.

1998 : During the Clinton administration, Boeing test drops the X-40A, a test vehicle that would later be developed into the X-37. The government's own National museum of the US Air Force [freely states](http://www.nationalmuseum.af.mil/factsheets/factsheet.asp?id...) "The SMV program aimed at developing a new generation of small and reusable, highly maneuverable space vehicles for deploying satellites, surveillance, and logistics missions."

1999 : Public acknowledged start date of the X-37 project. Obvious similarities between the X-40A, launched a year earlier, and the X-37 show that work had already been started on the project, in one form or another.

2004 : The Bush administration decides to shake up nasa and outlines it's [Vision for Space Exploration](http://www.nasa.gov/pdf/55583main_vision_space_exploration2....). In it, they outline the future of spaceflight laying out the, later cancelled, renewed efforts to send manned missions to the moon and later mars. In it they talk about a new generation of launch vehicles. This document is the beginning of the end for the already aging shuttle program. In it, they spell out that the shuttle program's only continuing purpose would be to finish the international space station.

2004 : Also in President George's plan is the further classification of the X-37/X-40 projects as they are [moved from NASA to Darpa](http://www.space.com/337-nasa-transfers-37-project-darpa.htm...) where a tighter lid can be kept on the whole project.

2006 : First Drop test of the X-37

2009 : Barack Obama is elected POTUS

22Apr2010 : First launch of the first X-37, Mission USA-212, and lasted 225 days

5Mar2011 : A different X-37 is launched and lasted 469 days

11Dec2012 : Another X-37 is launched and is still in orbit at the time of writing this. It is possibly that it is the same ship as was used in the first launch. As of today it has been in orbit, 657 days. USA-240 Mission

8Oct2014 : [NASA Partners with X-37B Program for Use of Former Space Shuttle Hangars](http://www.nasa.gov/press/2014/october/nasa-partners-with-x-...)

13Oct2014 : [The X-37B is reportedly going to land in California Tommorrow](http://news.yahoo.com/secretive-x-37b-military-space-plane-c...)

My personal conclusions on all this lead me to believe the following however I highly recommend anyone with interest in the subject research it and make your own conclusions as I might have missed something: Due to the long amount of time they have kept each X-37 in orbit and the apparent desire to keep one in orbit at any given time, I personally believe that the mission is ongoing and of perceived strategic importance to the united states. Given that the US government itself has described the X-37's predecessor as a "highly maneuverable space vehicle for deploying satellites, surveillance, and logistics missions" I believe this is exactly what it is doing. It is an orbital space plane with a next generation optics and surveillance package that has the added ability of being able to change it's orbital inclination in the event that a certain spot on the earth needs observation urgently. Changing your orbital inclination costs a lot of fuel so you still want to be able to deorbit to be able to refuel and have another ready to take it's place when you do this. This also gives your engineers at Boeing time to make improvements and upgrades on one bird while the other is flying keeping your optics and sensors at the cutting edge all the time.
