Matango, Fungus of Terror!

Tuesday, November 5th, 2013

By way of the YCombinator news feed:

From around 420 to 350 million years ago, when land plants were still the relatively new kids on the evolutionary block and “the tallest trees stood just a few feet high,” giant spires of life poked from the Earth. “The ancient organism boasted trunks up to 24 feet (8 meters) high and as wide as three feet (one meter),” said National Geographic in 2007. With the help of a fossil dug up in Saudi Arabia scientists finally figured out what the giant creature was: a fungus. (We think.)

(You know, I’d read about Mantango in one of the Golden Turkey books, but it wasn’t until I read the Wikipedia entry that I became aware it was based on a William Hope Hodgson short story.)

I was looking at my “Squid” tag the other day (no, really, I am not making this up) and thinking “I don’t use this tag nearly enough”.

Well, the Monterey Bay Aquarium Research Institute (MBARI for short) has their own YouTube channel. And they have a tradition of posting themed videos for Halloween.

This year’s video is “Spooky Eyes”, and it is chock-full of squidly goodness. (There are also some non-squid creatures in it.)

I also kind of like the music in this video. It sounds a little like a toy piano or maybe a child’s keyboard. The title of the piece is “Halloween Sputnik” by Richard Desilets, in case it catches your ear as well.

There’s a playlist of MBARI’s other Halloween themed videos, including “Big Teeth” and “Predators and Scavengers”.

And if you don’t want to watch the video, the LAT has a slideshow based on it.

Scentee, a Japanese tech brand, has created a product that attaches to your smartphone and releases a scent. The plug-in accessory fits into the headphone socket of a smartphone (iPhone and Android). The device works with a companion app that tells it to spray a burst of fragrance into the air when you receive a message.

Available scents are claimed to include:

…rose, mint, curry, jasmine, cinnamon roll, lavender, apple, strawberry, ylang-ylang (a fragrant flower), coconut, and if you remember the fried corn soup fritters at KFC Japan from earlier this year, the corn soup scent should come as no surprise. There’s also a limited-edition Korean BBQ collection with two meat scents and baked potato. A bacon scent is in the works.

Yeah, I’ll believe it when I see it in action. But even if this does turn out to be real, and not a hoax, I still think it is a damn stupid idea. (Anyone remember the iSmell?)

Also:

Almost as cool as making the theme song to “The Wire” (the Season 5 version) your ringtone … almost.

Oh, bullshit. Everyone knows the Season 1 version (with the Blind Boys of Alabama) is the best version.

Edited to add: I have been challenged to provide support for the above statement.

Here’s a handy page that contains YouTube versions of the theme song from all five seasons.

Big dismal science.

Happy Halloween, everyone.

Dean Karlan lives in New Haven, Connecticut. He gets a lot of trick-or-treaters in his neighborhood: “Residents say the area’s popularity is because the houses are so close together, minimizing the door-to-door travel time for trick-or-treaters.”

Dr. Karlan is also a behavioral economist. So why not combine the two and do science experiments on children?

Last year’s study found that 38% of kids 9 and older who saw a poster of First Lady Michelle Obama chose fruit instead of candy — twice as many as those who made that choice after seeing Ann Romney, wife of 2012 Republican presidential candidate Mitt Romney. The study indicated that the first lady’s “Let’s Move” campaign, promoting healthy living for children, appeared to be reaching its target audience.

In other experiments, Karlan has found that the more generic the costume is, the more likely it is that the child will choose a see-through bag with candy in it over a non-transparent bag. Karlan has also found that…

…older children would change their stated political party loyalty if it meant getting a little more candy. Younger children, however, could not be bribed, and remained steadfast.

I’d like to see a follow-up to this experiment where children get equal amounts of candy, but those who identify as Democrats have more of their candy confiscated by the researchers.

This year, the study aims to test whether some children are inherently planners — whether they planned their costume ahead of time or procrastinated until the last minute, and whether they have a plan for how they will eat their candy. They’ll weigh their answers against whether kids choose fruit or give into the easy temptation of candy.

One more thing I’d like to know: why isn’t Dubner interviewing Karlan, instead of doing a re-run this week? With all due respect, guys, it seems like you’ve been doing a lot of re-runs recently, and that doesn’t really motivate me to give you money.

(This also reminds me that my youngest niece has gotten to the age where I can start doing science experiments on with her. She’s still a little young for the economics based ones, though.)

Important safety tip (#18 in a series)

Saturday, October 12th, 2013

A while back, I suggested the words ‘f–king” and “b-tch”, along with the conjugate “f–king b-tch”, do not belong in a professional email.

To that list, I now suggest that the word “whore” be added.

Also: pay the writer! But that’s not really a “safety” tip…

Tom Clancy obit roundup: LAT. Appreciation from LAT. NYT. Baltimore Sun. A/V Club. WP.

In other news, the Dread Pirate Roberts graduated from Westlake. I’d also like to direct folks to Popehat, where former federal prosecutor Ken White has posted an analysis of the charges.

And it seems that the Brooklyn DA’s office has found at least one witness who says “the police coached him into giving false testimony”.

The witness, Sharron Ivory, gave crucial evidence in one of roughly 40 trial convictions handled by the detective, Louis Scarcella, that are now being reviewed by the Brooklyn district attorney’s office. The review was prompted by revelations that Mr. Scarcella sometimes engaged in questionable tactics, and may have helped frame an innocent man in another case.

Scarcella is not accused of being the person who got Mr. Ivory to lie:

Records show that it was not Mr. Scarcella who presented the photographs to Mr. Ivory. His role in the case involved obtaining the confession, which the defendant, Sundhe Moses, said he signed only because the detective had become physically abusive. When it came time to testify in court, Mr. Ivory ultimately did not identify Mr. Moses, but the jury, apparently persuaded by the confession, voted to convict.

Consumer advisory: iTunes 11.1

If you have not updated to iTunes 11.1 yet, don’t.

atp

This is a screen snapshot from my iTunes 11.1 of one of the podcasts I listen to, the Accidental Tech Podcast. Click to embiggen.

In spite of what you see in the “Plays” column, I have actually listened to every episode of ATP. I delete podcasts from iTunes as I listen to them.

When I “upgraded” to 11.1, all of these podcasts I had already listened to, and deleted from iTunes, popped back in with that little “cloud” icon under the “Unplayed” column. Apparently, Apple wants me to know that these podcasts are available in “the cloud”.

That’s great, Apple, but if I want to find an episode I’ve missed, I can go to the podcast’s page in iTunes, or to the podcast’s website. How do I turn off the display of podcasts in “the cloud”?

Surprise! According to everything I’ve been able to find on Apple’s support sites, you can’t. You can’t delete them from iTunes. You can’t get rid of them. The “Show iTunes purchases in the cloud” option does nothing for podcasts.

You can use the “My Podcasts” view to show just the podcasts you’ve downloaded and not deleted, without the “cloud” podcasts. But I have sound reasons for preferring the “List” view over “My Podcasts” – “List” shows you more information and less graphics.

Bad job, Apple. May the person who decided on this develop a case of painful rectal itch.

There’s an interesting post over at the Cryptographic Engineering blog about Duel-EC.

For those not following the story, Dual-EC is a pseudorandom number generator proposed by NIST for international use back in 2006. Just a few months later, Shumow and Ferguson made cryptographic history by pointing out that there might be an NSA backdoor in the algorithm. This possibility — fairly remarkable for an algorithm of this type — looked bad and smelled worse. If true, it spelled almost certain doom for anyone relying on Dual-EC to keep their system safe from spying eyes.

The post itself is pretty wonky, but a couple of scattershot points:

Flaw #1: Dual-EC has no security proof.
Let me spell this out as clearly as I can. In the course of proposing this complex and slow new PRG where the only damn reason you’d ever use the thing is for its security reduction, NIST forgot to provide one. This is like selling someone a Mercedes and forgetting to attach the hood ornament.

Flaw #3: You can guess the original EC point from looking at the output bits.

Flaw #4: If you know a certain property about the Dual_EC parameters, and can recover an output point, you can predict all subsequent outputs of the generator.

This is a huge deal in the case of SSL/TLS, for example. If I use the Dual-EC PRG to generate the “Client Random” nonce transmitted in the beginning of an SSL connection, then the NSA will be able to predict the “Pre-Master” secret that I’m going to generate during the RSA handshake. Given this information the connection is now a cleartext read. This is not good.

Flaw #5: Nobody knows where the recommended parameters came from.

So does all of this amount to a backdoor? Quoth Matthew Green,

including some kind of hypothetical backdoor would be a horrible, horrific idea — one that would almost certainly blow back at us.
You’d think people with common sense would realize this. Unfortunately we can’t count on that anymore.

(Subject line hattip.)

(You know, I’m halfway tempted to start a Kickstarter for a truly random random number generator. Something based off atomic decay, perhaps. What’s stopping me is:

  1. I have no electronics design skills or ability. Of course, I could hire someone, but…
  2. I’d be surprised if someone hasn’t already done this.)

(Edited to add: You could just get your random numbers from here, of course, while you’re waiting for the revolution. Nothing wrong with that plan, is there?)

(Speaking of Big John von Neumann, I just finished Turing’s Cathedral: The Origins of the Digital Universe, about the early history of computing, with a strong concentration on the Princeton Institute for Advanced Study and von Neumann’s work. It’s an interesting book – I think it serves as a good introductory biography of von Neumann. Dyson wanders a bit into the mystic towards the end, a little bit more than I would have liked, which prevents me from fully endorsing it. But if you liked Project Orion: The True Story of the Atomic Spaceship, you should enjoy this book as well.)

The Rational Choices of Crack Addicts

Answer after the jump.

Toes in the water.

Tuesday, September 3rd, 2013

Sorry about the short blogging quasi-hiatus there.

After work on Friday, I drove down to San Antonio for LoneStarCon 3, the 71st World Science Fiction Convention. It was a swell time. I got to hang out with several friends, including Mike the Musicologist, Andrew the Colossus of Roads, RoadRich, and Lawrence, who was doing a land office business in books. (Who says people don’t read any more? I covered the table for him a little bit, and by Ghu the books were flying off the table like snow crab legs at an all you can eat Chinese buffet.)

I haven’t been down to San Antonio for reasons other than medical for years, and hadn’t been on the RiverWalk since LoneStarCon2. I’d forgotten how nice the RiverWalk is, even though the vendors make things a bit crowded. (I don’t remember there being as many sidewalk vendors there last time I was down. But I’m getting old, and memory fades.)

Mike the Musicologist did most of the meal planning. Breakfast for two out of three of the days we were there was in the Marriott Rivercenter, mostly for reasons of timing. However, it is a pretty good buffet; I’d go so far as to say, with the custom omelets and made-to-order waffles, it comes close to being worth $20+tax and tip. Especially since I really didn’t see any breakfast places near the hotels or along the Riverwalk. (McDonalds and Whataburger excepted. There was also a Denny’s across the street from the Rivercenter; but literally the first thing I heard when I got to the hotel was that a mutual acquaintance of ours got food poisoning from the Denny’s bacon.)

The one non-Marriott breakfast was at the Magnolia Pancake Haus on Embassy Oaks, which was packed to the gills. We waited 40 minutes for a table, but the Munchener Apfel Pfannekuchen was worth it. I’d love to go back (and maybe try the wild mushroom hash) but I’d make sure I brought a good book.

(At some point in the near future, I want to do a post on how tablets, and especially the iPad, are transforming the restaurant industry, with Magnolia being one of my examples.)

We also had an excellent meal at Moroccan Bites (I loved the lamb shank and the chicken bites) and a pretty good meal at a place called Charlie Wants a Burger. (I had the pulled pork sandwich. And wings.) Sunday night we went to Fogo de Chao…which, you know, is Fogo de Chao. If you want huge amounts of roasted meat, you know what you’re getting into. For reasons I won’t discuss here (think Tim Cahill’s rule #6, corollary 1), I just had the salad bar. Which is actually a reasonable thing to do at Fogo de Chao (especially since you also get to eat the fried polenta, bananas, and cheese rolls), and I didn’t feel ripped off at $22.50. (I did feel gouged by the $3.25 iced tea. Note to self: water next time.)

(If you think you detected a trend, you may be right: Moroccan Bites and Magnolia have both been on Diners, Drive-Ins, and Dives. Guy Fieri may have problems running a place of his own, but as far as recommendations go, he’s batting 100% with me.)

Oddly enough, I bought more t-shirts (three) than I did books (two). Of course, one of those shirts is a gift for my brother. And one of those shirts I don’t actually have yet (they’re shipping it). And one of those books I bought mostly so I could support my friends. (I would have bought more books, but nobody had any Robert Frezza. “The Whistling Pig” was the theme to my last few months at 4LCC.)

I do want to say a few words about the best thing that happened at the convention. I don’t like bragging about famous people I know, mostly because I’m always afraid someone will ask them about me and they’ll say “Dwight who?” (Or, if they’re talking to Gardner Dozois, “That a–hole Dwight?!”)

(If you’ve never met Gardner in person, let’s just say he has a puckish sense of humor.)

But I digress. The best thing that happened at the convention is that one of my closest friends in the world won the Hugo Award for Best Novelette. That put the cap on a pretty swell weekend.

Congrats, again, Pat.

Quote(s) of the day.

Friday, August 30th, 2013

I probably would have posted these even if Lawrence hadn’t done a quote of the day, because: Derek Lowe! More “Things I Won’t Work With“!

But I can’t decide which one I like more:

Explosions are definitely underappreciated as a mixing technique…

Or:

The hyenas will have to remain unspayed, because it’s time to add fresh azide to the horrible mercury prep.

“Spaying hyenas” has so many possible uses.

“How was work today, honey?”
“Spaying hyenas.”

The economics of expensive fluids.

Monday, August 26th, 2013

Would you believe that IV fluid (specifically, normal saline) is almost as cheap as house-brand cola at the grocery store?

The limit for one liter of normal saline (a little more than a quart) went to $1.07 this year from 46 cents in 2010, an increase manufacturers linked to the cost of raw materials, fuel and transportation. That would seem to make it the rare medical item that is cheaper in the United States than in France, where the price at a typical hospital in Paris last year was 3.62 euros, or $4.73.

That is, if you buy it in bulk from the manufacturer. If you go to the hospital and get an IV…

The charges included “IV therapy,” billed at $787 for the adult and $393 for the child, which suggests that the difference in the amount of saline infused, typically less than a liter, could alone account for several hundred dollars.

Of course, there’s hospital overhead and such involved. You don’t expect to go to Best Buy and pay wholesale price for a laptop, so why would you expect to pay wholesale for IV fluid? But isn’t $786 a lot of markup?

At White Plains Hospital, a patient with private insurance from Aetna was charged $91 for one unit of Hospira IV that cost the hospital 86 cents, according to a hospital spokeswoman, Eliza O’Neill.
Ms. O’Neill defended the markup as “consistent with industry standards.” She said it reflected “not only the cost of the solution but a variety of related services and processes,” like procurement, biomedical handling and storage, apparently not included in a charge of $127 for administering the IV and $893 for emergency-room services.

SmarterTimes has one take on this. I have another. Actually, I have two:

  1. If you go to watch a dragon dance, don’t eat lunch from food stalls at the Buddhist monastery.
  2. This is one of the reasons I have qualms about health care reform. I really do believe the system is broken and needs reform. But many of the proposed changes seem like tugging at a protruding wire in a deeply intertwingled snarl of wiring, without knowing whether you’re going to rip something vital loose or shock yourself or both.

This also gives me a chance to plug a forthcoming paperback that I’m very excited about: David Goldhill’s Catastrophic Care: How American Health Care Killed My Father–and How We Can Fix It. I haven’t read Goldhill’s book yet, but I have read (and written about, even) his 2009 Atlantic essay that this book is based on. I won’t say it was a huge influence on my thinking, but the essay did help me clarify many of my own thoughts about what’s wrong with the system (particularly the role of insurance) and how things could be changed.

I’m not sure how applicable Goldhill’s prescriptions are to this incident. Much of what he talks about involves changes in routine health care, such as providing consumers with better cost information; being poisoned by monks at a dragon dance is the kind of catastrophic event you’d figure should be covered by insurance, and not the sort of thing where you shop around for the best deal on IV fluids and antibiotics.

Still, this does give me a chance to plug his book, which I was previously unaware of…

NYT headline:

Rodriguez’s Lawyer Calls Baseball’s Offer a ‘Trap’

(Edited to add: I am willing to offer karma points and gratitude for a photoshop of Admiral Ackbar in a Yankees uniform.)

At least Richard Cohen is consistent. Here’s a man who’s never met a totalitarian initiative he doesn’t like.

Speaking of NYC and guns…

“A lot of firepower,” Mayor Michael R. Bloomberg mused as he paused to look at some of the 254 guns — large-caliber pistols and military-grade weapons modified to improve aim and avoid detection —

Say what?

Officials said two men — Earl Campbell of Rock Hill, S.C., and Walter Walker of Sanford, N.C. — bought stolen guns from associates or used straw purchasers at legitimate stores, then simply loaded them into suitcases and boarded cheap buses to Chinatown or occasionally drove in private cars. Most of the deals were for several weapons; one sale, for $9,700, included 14 weapons.

So let’s see. NYC has strict gun control. So crooks are stealing weapons (already illegal) or engaging in “straw purchases” (also illegal, and rarely prosecuted by the Feds). So what we need is more gun control, and also stop and frisk.

During the investigation, which emerged last August from an unrelated drug case, the undercover detective watched as two of the suspects struggled to assemble an assault rifle during a sale. They even looked at an instructional video on their smartphone, said Bridget G. Brennan, the city’s special narcotics prosecutor, before the detective agreed to buy the gun in pieces.

I would laugh at these guys, but…I’ve got my own embarrassing gun related issue (which I will write more about at some time in the future; no, it wasn’t a negligent discharge, I’m just having problems getting something to run right), so I’m withholding the laughter for now.
