Nine Giga-pixel Image of the Milky Way



From The Verge.


Using images from the ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), researchers have stitched together a massive nine-gigapixel image of the Milky Way galaxy. The 108,200 x 81,500 image consists of nearly nine billion pixels, and was used to create a catalog of 84 million stars. Researchers claim that this is the largest image of its kind — the first to catalog the entire bulge of the Milky Way galaxy — and contains ten times more stars than any previous study.

My favorite part is where it says “Click to Enlarge.”

D-Wave uses quantum method to solve protein folding problem

RT @physorg_com

Report by Lisa Zyga
The study, “Finding low-energy conformations of lattice protein models by quantum annealing,” is published in a recent issue of Nature’s Scientific Reports. The computer used quantum annealing to find the lowest-energy protein configuration by solving for the configuration as an optimization problem, where the optimal state was the lowest-energy state. Proteins can be folded in a large number of ways because they’re made up of many chains of amino acids. Yet somehow, proteins almost always manage to fold themselves in the correct configuration (when they don’t fold correctly, they can cause misfolded-protein diseases such as Alzheimer's, Huntington's, and Parkinson's). Scientists think that proteins fold themselves correctly because the correct configuration is also the state of lowest energy, the state at which the protein becomes stable.

Gigaom's Four Part Series on North Carolina Data Centers

RT @gigaom

Article by Katie Fehrenbacher.

 Apple, Google, Facebook and other Internet giants have chosen a several hundred-mile stretch of land north of Charlotte, North Carolina to build their mega east coast data centers. These are some of the largest data centers in the world for some of the most powerful Internet and tech companies on the planet. Why here? Will this continue in the future? And what’s been the affect on the local communities? Check out the 4-part series I published this week on North Carolina’s mega data center cluster, the resources that go into these things, and why one, in particular, is betting on clean power.

Yahoo Passwords Leak

I've found it really difficult to find good, responsible news reports on this event.  I'm sure Steve Gibson (grc.com) will report on it on this week's upcoming Security Now.

Here's a pretty good article on this event at Cnet.

In this case, you're password would only have been compromised if you'd logged into the Yahoo Contributor Network, apparently also known as Yahoo Voices, and previous to Yahoo,  Associated Content which Yahoo acquired.

Here's the main, important advice which has been true for a long time, maybe always.  Please don't use the same password for more than one site.  I like the recommendation to use LastPass at lastpass.com.  It gives you a secure way to keep up with and use your passwords.

The only reason you need to change your password on other sites than Yahoo is if you (ever) used the same passwords on them.

Seesmic



FlipBoard is beautiful.  I've been using it since about the first day it became available on Android for general users.  Maybe three weeks?

However, in the past couple of days I've gone back to reading Twitter, meaning news in general, on Seesmic on my phone.  It's just faster to read down through the tweets without having to flip over the images.

Again, the experience of using FlipBoard, the fonts and the look are a joy to use.  I'll probably use FlipBoard when I want to be entertained a bit more by my news reading experience than simply getting the information.

I do have one complaint.  Some web sites rendered on FlipBoard are a little hard to use.  I find myself fighting with the (already annoying) Android pinch-zoom-scroll feature to get the text zoomed and placed in the FlipBoard version.  I finally adopted the practice of just tapping the drop down and selecting View On Web to go to Chrome.  Note this is on web sites that FlipBoard renders in their usual web view and not in a FlipBoard-optimized version.  I think.

Why is Clojure so slow?



RT @newsycombinator

From Martin's Computer Programming Blog.


What we can see it that Java itself accounts for 0.35s of the startup time, but unfortunately Clojure adds another second(!) on top of that. This 1.3s pause before main gets called is why Clojure is unsuitable for "terminal scripts". The running time of any scripts (like lein or starting the REPL) will be totally dominated by the startup time. Most Clojure developers will not notice this too much to, since they spend almost all their time in the REPL itself, but users of those Clojure programs will!

My summary is that it spends 95% of the startup-time loading the clojure.core namespace (the clojure.lang.RT class in particular) and filling out all the metadata/docstrings etc for the methods. This process stresses the GC quite a bit, some 130k objects are allocated and 90k free-d during multiple invokes of the GC (3-6 times), the building up of meta data is one big source of this massive object churn.

Leap Second Problems

RT @arstechnica

“Almost exactly 24 hours ago, the Internet faced the most recent one. It didn't go so well. Headlines have varied—calling the incident "Y2K 2.0," declaring that the "Internet died," or simply saying it, "Gave the Internet a Really Bad Headache." Hyperbolic? Sure, but the following sites did confirm leap second-related outages…”


Google and the Leap Second






Soon after the advent of ticking clocks, scientists observed that the time told by them (and now, much more accurate clocks), and the time told by the Earth's position were rarely exactly the same. It turns out that being on a revolving imperfect sphere floating in space, being reshaped by earthquakes and volcanic eruptions, and being dragged around by gravitational forces makes your rotation somewhat irregular. Who knew?

These fluctuations in Earth’s rotational speed mean that even very accurate clocks, like the atomic clocks used by global timekeeping services, occasionally have to be adjusted slightly to bring them in line with “solar time.” There have been 24 such adjustments, called “leap seconds,” since they were introduced in 1972. Their effect on technology has become more and more profound as people come to rely on fast, accurate and reliable technology.

Re-Tweeting



Who do I recommend following on Twitter?  Recently I was talking to a co-worker about how I had switched from using RSS to Twitter for reading news a few years ago (meaning at least two, I'm not sure without checking).  That leads to the question, who would I recommend following.

In the past I would have said to just look at my re-tweets to gather a recommended list.  However, most recently I've taken to writing blog posts here instead of re-tweeting most of the time, though I'll still re-tweet short items of interest.   When I post, I usually just link back to the original article so there's not any mention of who I got the article link from on Twitter.

I'm going to experiment with ways to acknowledge the original tweets and Twitter account, starting with a classic RT at the beginning of the post.  However, if that's just too repulsive to look at on an otherwise nice looking blog post, the next idea will be some other Twitter acknowledgement, maybe at the bottom.

The nice thing about an RT is that it will show up in the Twitter feed that's reduced from my blog in the traditional way.  We'll see how this goes.

Why we owe it all to Alan Turing

by Dan Crow on Gigaom.

…he, more than anyone, can be said to be the father of the computer. So what was his great insight? What is it he did that shaped our world so profoundly?

The Church-Turing Thesis has two very important implications.

First, it recognized the fundamental limitations of the system — for example, that there are some programs that are not computable by any machine.

But it was the second implication that was most profound: within its limitations, a Turing Machine can be programmed to run any piece of software. In fact, one of the programs that can be run on a Turing Machine is a simulation of a Turing Machine. And the simulated Turing Machine can itself run any program that a Turing Machine can run.

This is the genius of Turing’s work, his key insight. He has defined a “Universal Machine” — one that can run simulations so powerful they are themselves universal machines.

A Bit More on Bradbury

One of my favorite writers, Jerry Pournelle, wrote on his blog, “At one time the whole genre was dominated by ‘ABC’, Asimov, Bradbury, and Clarke, although usually someone would quickly add Robert Heinlein. Now the Big Four are gone. They will all be missed.”

Verified by Visa?

I was submitting an order on-line for refurbished electronics from a site I normally don't use.  A window popped up for Verified by Visa asking for the CVV code again, also the last four digits of my social security number and asking me to create a password.  It has our bank's logo on it.

Of course I was suspicious.  I poked around the web and found the actual Visa site as well as this article which pretty much explains what happened to me along with the program.

I also went to my bank's web site and found a discussion of the program there.

The bottom line:  This is a good thing.  It essentially adds a password to your credit card.  You have to supply this password when you use your card on-line.

I would have appreciated more warning but maybe there was something from the bank that I ignored.

So Long Ray Bradbury



I enjoyed many of his short stories, particularly in high school.  This is a very nice video of him at JPL on the eve of Mariner 9 entering Mars orbit in 1971.  He's sitting next to Arthur C.

My Favorite Venus Transit Video



It's pretty clear that NASA's Solar Dynamics Observatory (SDO) has stolen the show, at least on Youtube and Twitter, with it's videos of the recent Venus transit.  However, my favorite video is not the popular, creepy (yet beautiful!) extreme ultraviolet images of a flat-looking black circle moving across amazing prominences and other features in the hot solar corona.  

My favorite is this video in orange light where you can clearly see sunlight scattered around Venus' atmosphere as it moves in front of the Sun.  The limb of the Sun also seems to be refracted by the planet's atmosphere.

These images were made by the SDO's Heliocentric and Magnetic Imager (HMI) which observes at a wavelength of an Fe I (unionized iron) absorption line at λ6173.

Melancholia Misses the Physics





Melancholia was a dark and slightly depressing movie but with some interesting special effects.  I watched it on a recommendation from Hal.  However, they got the science wrong on a couple of basic accounts and I think I know why.

If a terrestrial planet (dirt and rock) came that close to the Earth, there would be two major effects.  First, the tidal force on the Earth would be extreme.  The Moon's diameter is more like the size of the United States and look at it's tidal force.  Such an approaching big planet as the fictional Melancholia would basically put the Earth's surface through a food processor before any collision ever occurred.  I'm not sure if the tidal force would be enough to completely destroy the Earth, but anything and anyone on or near the Earth wouldn't know the difference.

Tidal force is caused by the difference in gravitational force between the closest and farthest parts of one body caused by another.  This effect of the Moon on the Earth causes it's ocean surface to bulge toward and away from the Moon.  The Earth's crust also does the same but to a lesser and non-catastrophic extent.

Second, the two bodies would move about their mutual center of gravity.  The Earth would be perturbed completely out of it's orbit by the encounter in some crazy way.   It could still involve a single close encounter, again with both planets being destructively disturbed by the tidal forces of each on the other, followed by a later, final impact, but there's no telling what their mutual trajectory would look like.  What is nearly certain is that the Earth would not continue on it's nearly-circular orbital path.

So surely they had a science/astronomical advisor for the movie.  Why such fundamental mistakes?  I propose that when they consulted their expert, they were thinking of a small asteroid collision with a body more the size of a large metropolis or a state.  A small  body wouldn't perturb the Earth from it's orbit and wouldn't have much tidal effect.  However, the impact would be catastrophic.

Later, because they had brilliant ideas about the look and effect of a  giant planet approach and final impact, they changed the threatening body but they didn't go back and consult the expert.  They just kept the path from the previous discussions.

On the occasion of Robert A. Moog's birthday, here's an excellent interview from The Guardian.  The original interview was by Don Snowden, published in the Los Angeles Times in 1981.

A New York musician who had bought some of my equipment was there and he was in complete shock. He said, ‘This is the end of the world.’”

Emerson's wild-man-of-the-opera stage antics may have shocked some of Moog's more conventional customers but they thrilled many rock fans. ELP quickly became one of rock's most successful attractions and paved the way for other progressive rock bands like Yes and Genesis.

Why Have I Disappeared from Facebook?

Or at least, why am I not responding?

I have a few FB accounts and it seems that FB has decided I need to provide a phone number to keep them active.  Right now I can't log into most of them without providing a cell phone number.  I'm generally put off by this whole development and mostly inclined not to provide any information like that and just leave FB, at least on those accounts, behind.

For anyone who wants to read what I have to say, the good news is that I usually only post on FB an echo of what I post here.  You can always see what I have to say by reading this blog.  You always could.

Similarly, I've provided easy and effective ways to contact me.  You can, for example, use those to comment on or follow up on my postings here.

What I am missing out on are some postings and pictures by folks on the locked FB accounts, and even occasional messages.  Right now I can't reply to any of them and can't see many of them.

For most of the time I've not been a fan of FB and I'm less a fan than ever right now.  Who knows, though, they may yet emerge as the preferred way to communicate and stay in touch.  I expect the future holds some interesting surprise that I haven't imagined.

In the mean time, if you're looking for me, I'm still here where I've been the whole time.  That's the nice thing about centering communication, at least the outbound kind, on one's own blog.  You always have control of it and it can persist beyond the limits and misdirections of other services.

New Look

Well, now I've gone and done it.  For the first time in some six years (I think) I've changed the look of the site here.  I may make more changes over the coming days as I sort this out.

The site was looking a little old and, frankly, I didn't really like the current version of the look.   I did like the fonts, colors and general layout.

However, I'm clearly a fan of the lighter and more open looks and this one is an example of that.   I like the days being grouped this way.

I spent some time poking around with the text font.  This is currently Open Sans (I think).
