Seven Years of Opportunity...

APOD has a celebratory post up today – celebrating seven years on Mars by the amazing Opportunity explorer.  Designed for a mission of 90 days, it is still in nearly perfect condition seven years later.  It has now logged over 15 miles (27 km) of roving over the Martian surface, far more than its designers ever dreamed of.  It's also had its share of good luck: unexpectedly common dust devils have cleaned the accumulated dust off its solar panels on several occasions.  Without these lovely dust storms, Opportunity's solar panels would long ago have been blocked.

Opportunity's sibling rover Spirit is also still operational, but it has suffered more component failures (especially its wheels) and is now stuck in one place.  Nevertheless, it's still doing yeoman science work every day.

An Unserious Speech...

Peggy Noonan on Obama's State of the Union Speech - her lead:
It is a strange and confounding thing about this White House that the moment you finally think they have their act together—the moment they get in the groove and start to demonstrate that they do have some understanding of our country—they take the very next opportunity to prove anew that they do not have their act together, and are not in the groove. It's almost magical.

The State of the Union speech was not centrist, as it should have been, but merely mushy, and barely relevant. It wasted a perfectly good analogy—America is in a Sputnik moment—by following it with narrow, redundant and essentially meaningless initiatives. Rhetorically the speech lay there like a lox, as if the document itself knew it was dishonest, felt embarrassed, and wanted to curl up quietly in a corner of the podium and hide. But the president insisted on reading it.
What she said.

Mac Software Recommendations...

Quite a few things on this list that are new to me, and sound interesting...

Happy Music, Happy Feet...

Via my cousin Mike D.:



I was panting myself by the time they were finished...

She Lives Way Down the Street!

Very funny sermon, via my mom:

Shameless Plug...

For my company.  Our marketing folks just posted this little movie about our upcoming Winter 2011 release (coming in early February).  There are no technical details here; it's just setting the scene for them.

I love it that we do things like this movie!


Winning the Future...

As many others, including Sarah Palin, have observed: Obama's State of the Union theme “Winning the Future” is the wrong phrase to describe his leadership, but it's the right acronym.  The graphic is already viral...

Awesome.

She's Back!

Rachel Lucas is posting again, albeit only occasionally.  Here's one destined to be a classic: “Noodles that are Wrong”.

I go to work with a smile on my face on those days when Rachel has a new post...

M78 (in Orion)...

Jeez, it never looked like this in my telescope!  From APOD, of course...

Holey Moley!

It's like Christmas for geeks!

Sometimes, You're Just Amazed...

Just over a month ago, Frankie joined our little development team.  She keeps a blog that I think of as part of her recovery plan – recovery from a profoundly sad event in her life a couple of years ago (I'll let her tell that story through her blog).  The blog is called “Hope Rising”; a title that is hopeful in and of itself.

Well, this morning I visited her blog for the first time in a few days, and found this beautiful post.  The paragraph below was just one of several that I stopped and reread a few times:
My pursuit of hope introduced me to what I have come to call the space in between. The place in my life where what was is gone and what will be has yet to be revealed. It’s the place where the only road available is the one forged with decisions and consequences of my past and my only power is in choosing the demeanor with which I walk it. For me that road was letting go of Arielle and walking that road in pursuit of hope was my spoken choice.
Arielle is the subject of the sad event. The post this comes from is all about Frankie being ready to run in her first half-marathon – which she did on the next day.  That's her at right, crossing the finish line.

I'm proud to know you, Frankie.  And I'm looking forward to knowing you better...

Found Emu...

Seen on a piece of chipboard posted along side Lawson Valley Drive this morning on my way to work (at 4 am!):
Found Emu
Heh!

Update: added photos

Industry, Meet Statist...

TigerHawk explains, very clearly, how the Obama administration's failure to understand how capitalism works is wrecking our industrial jewel: the pharmaceuticals.  Read it and weep.  Then vote these assholes idiots out of office at every possible opportunity.

For the children.

And yourself...

Minimum Wage = Recovery Roadblock...

If it's not obvious to you why the minimum wage (at any level!) is a problem, then read Warren Meyer's excellent piece in Forbes.  Meyer, by the way, is the blogger at the always-interesting CoyoteBlog...

These Really Work!

Via my mom, who says she verified the following on Snopes:
Amazing Simple Home Remedies

1. Avoid cutting yourself when slicing vegetables by getting someone else to hold the knife while you chop.

2. Avoid arguments with females about lifting the toilet seat by using the sink instead.

3. High blood pressure sufferers – simply cut yourself and bleed for a few minutes, thus reducing the pressure on your veins. Remember to use a timer.

4. A mouse trap placed on top of your alarm clock will prevent you from rolling over and going back to sleep after you hit the snore button.

5. If you have a bad cough, take a large dose of laxatives. Then you'll be afraid to cough.

6. You only need two tools in life – WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

7. If you can't fix it with a hammer, you've got an electrical problem.

And the daily thought:

Some people are like slinkies – not really good for anything, but they bring a smile to your face when pushed down the stairs.
Yup, this is the kind of home I grew up in. Does that explain anything for you?

So You Think You're a JavaScript Whiz?

Try this mind-bender!  What does this JavaScript expression do, if executed in a browser?
($=[$=[]][(__=!$+$)[_=-~-~-~$]+({}+$)[_/_]+($$=($_=!''+$)[_/_]+$_[+$])])()[__[_/_]+__[_+~$]+$_[_]+$$](_/_)
The answer can be found here, once you give up trying to figure it out...

New Memory Technology...

This sounds very promising: a new semiconductor technology for non-volatile memory with the speed of volatile RAM.  Unlike some other, more exotic methods proposed over the years, this one doesn't require any advances in fabrication technology...

Alternative to OS/X Terminal...

In alpha right now.  It has some interesting features...

Public Key Cryptography Invented Earlier than We Thought?

Ask anyone interested in cryptography about public-key cryptography, and the names of Diffie, Hellman, Murkle, Rivest, Shamir, and Adleman will quickly arise.  They're the inventors of the concept of public-key cryptography as most of us know it.

Well, maybe not.  If this article is accurate, apparently the British government developed public-key cryptography independently and several years earlier than the six listed above.  The narrative sounds plausible to me, though of course I have no personal knowledge of any of it...

Wow!
