How the government protects us from salmonella

“A Bug in the System” is a February 2, 2015 New Yorker article about salmonella poisoning caused by America’s industrial chicken production system.

It turns out that the federal government spends your tax dollars on workers at the Centers for Disease Control and the US Department of Agriculture. These workers can figure out which products are making people sick. However they require a tremendous amount of evidence before they can suggest to a manufacturer that products be recalled and these recalls are strictly voluntary.

Why do we pay taxes for antitrust law enforcement?

Staples seems to be confident in its ability to buy Office Depot (CNN), thus creating a nationwide monopoly for office supply retail: “There’s about to be one game in town when it comes to office supplies.” Presumably the folks involved have researched the likely federal response and concluded that this attack on the consumer will be approved.

I guess that leads to two questions:

  1. why do we pay the salaries, benefits, and pensions of antitrust regulators if it is even conceivable for something like this to be approved?
  2. why do Americans bother studying classical “free market” economics if the real economy will be dominated by monopolies like “Staplot”?

Job opportunities for Math PhDs

“The Pursuit of Beauty” is a New Yorker (Feb 2) article about one of the world’s leading mathematicians, who obtained his first standard academic job, at University of New Hampshire, at age 59. What kind of job did he have for many of the years since he received his PhD?

A member of the group, a chemist in a lab, opened a Subway franchise as a means of raising money. “Since Tom was a genius at numbers,” another member of the group told me, “he was invited to help him.” Zhang kept the books. “Sometimes, if it was busy at the store, I helped with the cash register,” Zhang told me recently. “Even I knew how to make the sandwiches, but I didn’t do it so much.” When Zhang wasn’t working, he would go to the library at the University of Kentucky and read journals in algebraic geometry and number theory. “For years, I didn’t really keep up my dream in mathematics,” he said.

All that he needed to do to get a “real job”was solve a problem that had stymied mathematicians since the 19th Century….

Which microphone sounds better?

Folks:

I want to publish some narrated slide shows (previous posting). I’ve recorded myself reading from an unpublished novel that I have written. The first MP3 below is using a regular microphone. The second is made with a headset noise-cancelling mic that presumably gets rid of more of the room sound. I would be very interested in readers’ opinions as to which sounds better for a slide show.

Note that both were recorded in Audacity, processed with the “Compressor Effect,” and output to MP3.

Obamacare means that more people have to file tax returns?

A friend who is close to 65 and retired, but not collecting Social Security, earns less than $10,150 per year. Therefore she should not have to file an income tax return under IRS regulations. However, to purchase health insurance through the Massachusetts-run Obamacare exchange they need proof of what her income actually is. After about 15 phone calls to figure out why she couldn’t buy health insurance, the answer seems to be that she must file a tax return showing $0 in income. Then she will become eligible to purchase insurance at the government-established rate.

Is this true in all states or is it something unique to Massachusetts? If so, what’s the meaning of the IRS filing threshold? Won’t all Americans now have to file tax returns?

Why do online banking systems make only 3-12 months of transactions available?

Folks:

It is time to start thinking about taxes. I am interested in downloading 2014 transactions from two banks that offer online banking. One offers 12 months of transactions from their database (i.e., 11 out of 12 months of 2014). The other can go back for 3 months. Given the cost of hard drives and servers, why can’t I get all of my transactions for 2014? Google keeps 10 years of my email. What would be hard about keeping 5-10 years of numbers and short text strings for financial transactions?

All you have to be is white (to be credited with Super Bowl victory)?

From the movie Being There:

Louise (the former housekeeper, watching Chance on television): It’s for sure a white man’s world in America. Look here: I raised that boy since he was the size of a piss-ant. And I’ll say right now, he never learned to read and write. No, sir. Had no brains at all. Was stuffed with rice pudding between th’ ears. Shortchanged by the Lord, and dumb as a jackass. Look at him now! Yes, sir, all you’ve gotta be is white in America, to get whatever you want. Gobbledy-gook!

I’m not a football fan but I enjoyed watching this year’s Super Bowl at a friend’s house. To my untrained eye, the most critical point in the game was Patriot Malcolm Butler’s interception of a pass from the Seahawks quarterback during, literally, the last minute of the game. How did the New York Times describe the game? The summary on the home page:

With a late interception, Bill Belichick and Tom Brady won their fourth title, making them one of the most successful combinations of a coach and a quarterback in pro football.

So it was one of these two white guys who intercepted the pass? Clicking through to the full article contained some information about Butler, but not until the third paragraph (Belichick and Brady were mentioned in the first).

Did I miss something? Why doesn’t Malcolm Butler, who happens to be black, get the first credit?

Why do laptops have so little RAM?

My model of the computing world is that RAM is everything and everything should be (in) RAM. Yet if you look at high-end laptops they generally can’t be configured with more than 16 GB of RAM. Perhaps this is a limitation in Intel’s mobile chipsets, but, even if so, that just means that the folks at Intel have decided that laptops should have only 16 GB (about $125 worth), which leaves us with the same question of “Why?”

Example high-spec laptop: http://www.apple.com/macbook-pro/specs-retina/ ($3000 with 1 TB of PCIe SSD and yet just 16 GB of RAM max.)

Is RAM power-hungry? I wouldn’t have thought so compared to the screen backlight and what used to be a standard mechanical hard drive.

What’s the performance difference between RAM and PCIe flash storage (“PCIe SSD”)? Doesn’t running virtual memory result in a substantial performance hit compared to telling the operating system not to build a paging file? (maybe it doesn’t matter now that everyone has decided to run a tower of virtual machines, each of which in turn has virtual memory!)

Since processors aren’t giving us substantially more scalar performance it seems that a main way to benefit from Moore’s Law would be to have additional RAM. But the market isn’t developing in that direction. Why not?

Hoarders can tell us about less intense love affairs with stuff?

I’ve finished Kimberly Rae Miller’s Coming Clean: A Memoir, a well-written book about her unusual childhood spent with father with a serious hoarding problem and a mother with a related compulsive shopping problem. I have never seen any of the TV shows about this lifestyle so it was a shock to find out how bad it can get:

The third upstairs room was by all accounts the master bedroom; it was the largest in the house, but my parents had moved out of it when I was born, taking over a downstairs bedroom closer to my room. The only things that lived there now were a bed frame, a broken mirror, some newspapers from before I was born, and cat feces. It was the cleanest room in our house.

Shortly after we moved into the new house, my parents stopped sharing a bedroom. My father took over the guest room, where he slept on a trundle bed. Because of his piles of paper, the trundle bed could only half extend. He slept on that lower bed, with papers on the floor piled to upper-mattress level and surrounding him on all sides. The upper mattress became a desk of sorts, with its own stash of newspapers, catalogs, and documents preserved above the tides of trash. My mother stayed in the master bedroom, and checking in with her was my first stop each morning. “Morning, honey. Come sit down,” my mom said. She seemed far more upbeat than was normal for a postfight morning.

The downstairs had become a relative swamp ground. It never seemed to dry out from the flooding, so when we did walk through it, the inches of trash would squish beneath our feet, creating an unsteady terrain.

We gave up the kitchen and survived solely on fast food and hermetically sealed snacks we could keep in our bedrooms.

My parents’ home is something else entirely. The papers are the easy part, but once they’re bagged and off to the dump, next comes the stuff. They have so much stuff. My father loves electronics, the more broken and useless the better. And office supplies. Bundles of Post-it notes, pens, pencils, scientific calculators, hole punchers, and staplers can be found in every room. While my mother’s postsurgical depression has certainly lessened over the years, her compulsive shopping for things they do not need with money they do not have did not. She will never admit that she is part of the problem now, insisting that she will return most of what she buys. But things don’t get sent back; they have a habit of being engulfed by the stuff surrounding them. Each new box added to the house becomes a new surface to put things on.

[being away at college] felt like my reward for the years of shame I’d logged. No one there knew about the hate-fueled letters our neighbors left in our mailbox. They didn’t know how much I appreciated cafeteria food after having spent most of my teenage years eating hermetically sealed, chemically laden foods, because our kitchen had been left to rot under cobwebs and maggots. I no longer had to plan meetings with friends so they wouldn’t know where I lived.

When I returned to New York [from college], the things that had been so normal to me before—the rats, the sludge, the ubiquitous smell of mildew, the feeling that this was my home—were glaringly wrong. I couldn’t get used to them again.

Can people who can live for decades amid clutter and filth teach us anything about relatively normal lives? Miller pokes around in the academic literature to figure out why her parents might have hoarded:

In my reading I found that many hoarders have similar stories to my dad. Maybe they weren’t the children of abusive alcoholics, but they were emotionally neglected at some point in their development. One of the more popular theories behind the triggers for hoarding indicates that people who were neglected emotionally as children learn to form attachments to objects instead of people. When they do connect with others, they then keep any object that reminds them of that person as a way of holding on to those attachments.

In going through some of the people I know, the ones who had the happiest childhoods, with the best connections to their families, seem to be those who have spent the lowest percent of their income on stuff. By contrast, those whose parents separated or whose parents were prone to heavy drinking and other irresponsible behavior, are more likely to be shopaholics. The divorce litigators that we’ve interviewed for our forthcoming book relate experiences consistent with the psychology research reviewed by Miller. Divorce plaintiffs who came from the lowest social class and most dysfunctional families were the ones most motivated by money as litigants. Compared to people from middle-class and upper-class families, people whose own childhood was spent living on welfare and/or who were themselves children of divorce were more likely to insist that they couldn’t survive without designer clothing, imported German cars, and deluxe housing and pushed cases through to trial in hopes of squeezing the last dollar out of their former romantic relationship and their children.

What if you think you might be at risk of falling too deeply in love with stuff? Miller’s family experience suggests sticking with the smallest possible apartment:

“My parents never threw anything out,” my mother later confessed on the train ride back. “They had someone in regularly to clean, but there was always stuff everywhere. I remember thinking how great it was that they had a room reserved for junk.” “Your parents were hoarders?” I was trying to wrap my head around the fact that my family tree was messy down to the roots. “I grew up with it,” she said. “I guess that’s why I didn’t see it in your father until it was so out of hand.” “Was Daddy always like this?” “Oh, no. When we first moved in together, long before you were born, he was the complete opposite. We had this light green carpet that he obsessed over keeping clean. If anyone stepped on it with shoes on, he was there with a sponge, washing up their footsteps.” “When did he start collecting things?” I wondered how different my life would have been if my father was still obsessed with keeping things clean. “When we left the Bronx,” she told me. “It was like he had too much space.

What do readers think? What kind of person is most likely to become a hoarder? And is buying a lot of stuff on Amazon good clean American fun or does it place on the “hoarding spectrum”? And what is the best way to push back against the temptation to hoard?

The book also contains some pretty horrifying medical stuff. The mother was a victim of scoliosis starting in childhood. She endures crazy amounts of surgery that is of no value:

All the tests my mom had taken hadn’t revealed to the doctors that her spine had started to fuse to itself where her curvature was most acute. Putting the rods in would have pulled her vertebrae apart, potentially paralyzing her. “Come on,” he said. “The anesthesia should wear off soon. Let’s go wait for Mom to wake up.” There was nothing else to be done. My mother would be sent home in a few days to heal. Her abdominal muscles had been cut open during the first surgery and she could no longer walk on her own—she would spend the summer in bed, and then the fall, winter, and following spring. Her body was fitted for a plastic brace that would be used in the few instances she needed to be wheeled outside of the house. The brace would do the heavy lifting of keeping her upright until her own body was once again capable. The government job she’d had for years didn’t wait for her to recover; she lost her job while her body struggled to once again become functional.

Then she needs a relatively routine gall bladder operation but it goes awry and she is nearly killed.

The surgery, Dr. Abdallah explained, took a turn for the worse when he accidentally severed the vein going to her liver. Since the surgery was laparoscopic, using small incisions for minimum invasion, they couldn’t find the source of the bleeding quickly enough to prevent massive blood loss. In searching for the vein, they had ended up destroying her bile ducts. The lack of blood had caused her kidneys to go into distress. “Is she going to die?” Apparently this was the only question I was capable of asking anyone, first my father and then the doctor. It’s the only thing I cared about. “She’s not out of the woods yet. We’ll know more in the next forty-eight hours.” Dr. Abdallah looked as rattled as we did. He did these types of surgeries all the time. They weren’t supposed to end like this.

(Mom recovers but it takes about a year.)

The family has to move to hide from social services agencies that might have removed Miller from her parents’ care:

The kids were different in Grandma’s neighborhood. They seemed to be a little bit older than their seven or eight years. I was one of only two white kids in my class, a stark difference from my almost exclusively white classmates on Long Island. It never occurred to me that I didn’t fit in, and I felt the salutation of “new white girl” was as apt a description as any. There were no carpools or play dates to dodge—kids walked home after school and played with whomever they could find loitering the hallways of their building. During lunch they traded war stories in the cafeteria, stories about mothers leaving them with their grandparents and not coming back or cousins who had been killed. I didn’t talk about my dad because I had promised not to, and I doubted many of my classmates would understand what it was like to have too much, but for the first time my secret felt like a good thing. I fit in with these kids and their unfair lives.

Miller takes her own unfair life and, without self-pity, makes it an interesting and thought-provoking story even for those of us who’ve had reasonably fair lives.

Extreme Photography Instruction

A friend turned me onto this blog by a photography student. It works best if you go to the oldest posting in the archive and then read the newer ones in chronological order. Or start on the last page and keep clicking “previous page.” Here are a few samples of quotes from the professor:

The camera in your hand is not a passport for you to be a moron…

You can never ever “capture” anything in a photo. You haven’t captured a person in your photo because they’re not arrested there. All you can do is merely pause a real life situation. So don’t even think about saying capture and photograph in the same sentence or I will behead you.

Student: Do you have a fondest memory? Roma: Yes. It was the minute before I had to walk in here and talk to you. [This kind of student question does not typically arise in the Department of Electrical Engineering and Computer Science.]
