Health / Nutrition ... Society ... Technology ...

We just survived our first major mid-summer heat wave here in New Jersey. Despite my advanced old age I’m still a bit on the thin side (BMI about 19), so the hot weather doesn’t bother me as much as for many other people (but of course, I pay the price in January and February during the dark, sub-freezing days). I recently saw an article on the Boston Globe site suggesting that perhaps we could get used to living without as much air conditioning as most of us have now come to expect. I had to smile, as I never did come to expect AC that much; I don’t have an air conditioner in my apartment, and I hardly ever use the one in my car even in July and August (except when I have have someone with me who might get ugly if the A/C stayed off).

There was another recent note in the New Yorker reflecting on how cheap air conditioning has changed our social customs and expectations over the past few decades and generations. I’m old enough to remember when many small stores and workplaces didn’t have it. I worked for a railroad during my college summer vacations, and none of the offices where I did my job had it (the railroad was broke and couldn’t afford it). Many small stores didn’t have it either. There were still trains, buses and subway cars in the 1960s and early 70s that didn’t have it. But as the 70’s, 80s and 90s progressed, air conditioners became cheaper to buy and more efficient to run, and thus conquered the world. After 2000, the victory of air conditioning became complete with world manufacturing (read “made in China”) and stable energy costs (due mainly to hydro-fracking of natural gas and oil; ask the anti-fracking advocates if they are ready to turn their AC’s off in August). You have to be really, really poor these days to be deprived of air conditioning. Most public housing in Newark (where I work) has central air, and very few houses or multi-family buildings don’t have at least one or two AC’s in the window (sometimes with anti-break-in window bars shaped to accommodate such a unit).

So today, every car, store, home, apartment, workplace, bus, office, construction vehicle, control station, outhouse, just about every enclosed space that can be occupied by humans has AC. AC has become as much of a universally recognized right here in the USA as  »  continue reading …

Psychology ... Technology ...

I learned the rudiments of computer programming while in college, back in the mid-1970s. That was back in the dark ages of computers, when we keyed our programs on punch cards and brought them to a desk to be run. The output would come back in the form of a stack of thin 11 x 18 inch pages, listing all the stupid errors you made, along with all sorts of other computer system gibberish. So you’d re-punch some of your cards and try again; maybe in an hour or two you’d get your next set of results, hoping for a column or two of output numbers that made sense. That was my introduction to Fortran.

I didn’t make a career out of computer work, but knowing basic computer logic did help me in my various jobs over the next three decades. Still, I really only knew one half of the world of computer usage, as I never took a class on databases (COBOL, back then). To me, databases were like the dark side of the moon. I figured that they really weren’t all that important, and even if they were, how hard could it be? You just put numbers in indexed boxes, according to rows and columns. How complicated would it be to retrieve the number in row 1035, column 215 — say, sales of washing machines on July 23, 1974 at the Wichita store?

Only later in life did I come to know just how important the world of databases is. In 2000 I took a mid-life career hiatus and went through some classes at the now-defunct Chubb Top Gun program, which gave me  »  continue reading …

I’m probably into the final decade of my working life, so I’m not trying all that hard anymore to keep up with modern business trends. Nevertheless, I was chatting with the IT director at my job the other day, and we started talking about cloud computing. Our employer (a mid-sized local government agency) does not yet utilize cloud services, but the IT guy wants us to. I asked him, just why do we need to buy our computing services from “the cloud”. The IT guy in question is not very good at giving concise, relevant answers. And once again, he went off on one of his rambling monologues (sort of like my blog entries!). But somewhere in his speech, I heard a sentence that actually summed it up.

In a nutshell: my employer invested over a quarter million $$ into servers and enterprise software for e-mail, file storage and exchange, anti-virus, and other network management functions. This is the backbone of our data system, to which about 400 desktop computers are connected. We pay additional on-going sums for all the wiring within our main office, and to rent T-1 connection lines between our headquarters and 5 remote office locations. There are further fees for equipment repair, software maintenance, and the in-house staff needed to keep the servers healthy.

Going to the cloud means renting all of this capacity from some big company with a huge server bank, and connecting to it with individual high-speed internet connections from every local site. As such, we could do away with  »  continue reading …

Technology ...

I have not yet gotten myself a smart phone, and I don’t think I will anytime soon. I’ve seen many of the Androids and I-Phones out there, very impressive. They do all kinds of things; view pictures, take pictures, surf the Internet, figure out your location with GPS, tell you where restaurants and other stuff is in your vicinity, record voices, view and send e-mail and text messages, on and on. But you know what? Aside from the e-mail and texting, these smart phones remind me of Leatherman tools. I.e., those all-in-one things that look like a mutant pair of pliers; they have all sorts of mini-tools folding out from them. Akin to a Swiss knife on steroids!

But as with the Leatherman, almost none of the tools on a smart phone are the best possible forms of that tool. The I-Phone screens, although getting bigger,  »  continue reading …

I’m nearing the end of my fifth decade on this planet and I admittedly don’t know much about bring up kids (other than having watching my parents do it — and realizing many years later that they had done a much better job of it than I had thought at the time). But with that said, I wanted to discuss a recent “high profile homicide” involving a 12 year old girl, and the question of whether her parents had in some way failed by not training her to be wary of the situation that did her in. (Oh, and also some comments on the parents of the leading suspects.) Actually, I am not going to stand in judgment as to whether the parents in question “failed”. Obviously I cannot. In fact, I am sympathetic regarding all the challenges that parents face in the modern world, a world that is arguably more complex and uncertain than the one that my parents brought me up in.

The case in question is the murder of Autumn Pasquale in Clayton, NJ last Saturday. From what I’ve read, 12-year old Autumn was a fairly typical pre-teen Caucasian girl who lived in a single parent middle-class home. Her father is a postal worker; I couldn’t find out very much about her mother (Jennifer Cornwell). It appears that Ms. Cornwell presently lives in Cherry Hill. According to MyLife.com, Ms. Cornwell lived in Clayton until 2005, then was in Moorestown until 2010. If true, then Autumn lived with her father only. It’s uncertain if anyone else lived with them (Mr. Pasquale was pictured at Autumn’s funeral with his girlfriend Cheryl Evans).

During the week before last, Autumn had a brief discussion on Facebook with one of the suspects, 15 year old Justin Robinson of Clayton (an African American). The discussion was about a picture of Robinson’s BMX  »  continue reading …

Brain / Mind ... Psychology ... Technology ... Zen ...

I just found out about the Flynn Effect. The Flynn Effect is all about “psychometrics”, i.e. the measurement of human intelligence. About 28 years ago, a New Zealand sociology researcher who specializes in intelligence issues (whose last name is Flynn, not surprisingly) noticed that IQ scores have been rising steadily since at least the late 1940s, possibly since 1932. This effect has been taking place for both the highest and lowest scoring groups, as well as the middle. In effect, every new generation seems to be smarter than the one preceding it. That effect goes on today. I got out of college in 1975, so the class of 2012 has me and my peers beat by quite a bit — around 12 points (the effect is about 1/3 IQ point per year).

According to a recent Scientific American article (which brought me up to speed on this issue), the Flynn effect has been driven by one specific component of the IQ tests. It is not the component for arithmetic skills, nor the component for vocabulary skills; these scores have only gone up a bit over the past 60-odd years. The big jump is in “similarities”, the measurements of “fluid intelligence”. These are the tricky questions that attempt to gage a person’s “abstract intelligence”, the ability to see patterns (according to someone’s judgment about what patterns are important to see). I.e., which of the following animals is least like the others: orangutan, anteater, skunk and zebra; or BOOM is to 4267 as ZOOK is to (choose one): 3902, 54892, 3319 . . . or Mary is 16 years older than her brother, and is four times her sister’s age; if her sister was born two years before her brother, then . . . (these are not real IQ questions, of course).

Interestingly, the Sci Am article points out that Dr. Flynn and others feel that the Flynn Effect reflects changes in what society expects from us, both in  »  continue reading …

Outer Space ... Technology ...

The “space race” ain’t what it used to be in the USA. In the glory years of the 1960s and 70s, the USA put men on the moon and sent up the first orbiting space stations. But over the next 30 years, the dangerous-but-not-very-inspiring Space Shuttle soaked up most of the dwindling resources available for “exo-atmospheric” exploration, and ultimately left us at a dead end. For now, the only way for Americans to get into space is by hitching a ride aboard a Russian Soyuz vehicle (although NASA is working with Boeing, SpaceX and some other firms to get American manned vehicles back into earth orbit sometime before 2020 . . . or so they hope).

However, during these years, the USA had not done so badly in terms of sending increasingly sophisticated robot probes and vehicles to the planet next door, i.e. Mars. We’ve managed to get about 2 out of every 3 Mars missions successfully to the red planet, whether in orbit or to the surface via parachutes and rockets or bouncing air-bags. Now we’re kicking it up a notch with the Curiosity rover, a mission set to make a landing attempt in a few hours (around 1:30 AM Eastern Daylight Time on Monday, Aug 6), eight months after launch from Cape Canaveral. This baby is almost 5 times the size of previous scientific rovers, and will be a scientific lab on wheels. It will move more than twice as fast as the Sojourner and 5 times the Opportunity, and have twice as many scientific instruments on board to probe the Martian surface. Sounds great, makes you almost proud once again of the American space program.

But one problem . . . first this thing has to land first, using a wacky “sky hook” arrangement  »  continue reading …

In the 1960s, steel was still a big deal here in America. We made lots of it and we used lots of it. Our cars, refrigerators, beer cans, pipelines, guns and many buildings were made mostly of steel (unlike today, where such products have much plastic, aluminum, molded carbon, and other “composites” in them). So back around 1970 I noticed that US Steel was running ads on TV about their latest innovation, called “Cor-Ten” steel. Actually, Cor-Ten was invented in the 30s, but by the late 60’s US Steel felt it was ready for wide-scale marketing and production. Cor-Ten is now known as a “weathering steel“.

Basically, weathering steel was supposed to eliminate the need for paint. Most steel rusts away if not properly coated, usually with paint. But Cor-Ten supposedly rusted in a way that protects itself from further rust. I.e., when exposed to the elements, it creates a dark-red coating something like rust. But unlike rust, this coating keeps it from decaying any further . . . in theory. So long as you could put up with the rusty look to it, you didn’t need paint to keep the steel from frittering away . . . again, in theory. US Steel touted Cor Ten’s rusty look as somehow artistic or natural, something that people would like to see.

I was a big railroad enthusiast back in the 1970s, and I remember seeing new railroad cars made of Cor-Ten, complete with the “faux-rusty” look. But by the 1980s those cars disappeared. Could it be that Cor-Ten wasn’t the magic material that US Steel made it out to be?

Well, a quick web search confirms that notion. It turns out that  »  continue reading …

Personal Reflections ... Technology ...

I spent most of the past weekend in “geek mode”, as I just bought another computer (one of those ubiquitous HP/Compaq DC5000’s coming off five-year leases, which can be had with XP Pro for under $200). Well, I wanted to swap hard drives with an old Dell Dimension L with Windows 98 that I still keep running, mostly for sentimental purposes (the DC5000 comes with a 40 G Seagate drive, whereas I had an 80G Maxtor in the Dell). And of course I didn’t want to have to reload all the applications and the operating systems. My one “ace card” here is that I have Norton Ghost installed on both of these computers. But the handicap is that I don’t have a CD burner or any other convenient way to get a Ghost image out of the Dimension L. That was one handicap, anyway. I also had to repartition the drives, and forgot how to boot to DOS and use G disk. Then I also forgot how to take the hard drive out of the Dimension L (finally found where the screws are), and I had to search to find the hard drive in the HP (small form factor, everything is scrunched in).

This all made for two clumsy days of trial-and-error work. I do have a third computer (yes, another Dimension L, that one with Win2K) with a CD burner and a slow USB wire device to exchange files with the W98 Dell. So I was able to get a spanned image of the C drive over to the Win2K box, and then burned those spans to disk. But guess what? That doesn’t work, you can’t copy an image spanned to a folder onto individual disks and expect it to install correctly. So I had to partition the 40 G hard drive going into the W98, then make a Ghost image of the spanned Ghost images and put that directly to spanned disks, install that image on the extended partition (D drive) and then Ghost those spanned files over to the primary partition (C drive). Yikes! But it all finally worked; both the HP and the old Dell still had their respective “minds” (operating systems and software applications), despite swapping their “brains” (hard drives).

I must admit that without the Internet and Google, I probably couldn’t have done this. The net is a great place to go with a computer crisis. The chances that someone before you has had the same problem is pretty good. I had to look up a number of things over the weekend, and usually got some good pointers on what to do next. I will say, though, that sometimes you really have to sift through a lot of chaff in order to get to the answer. Here are two examples. When using G disk (an old-fashioned unfriendly DOS format), I was getting some discouraging responses to my command inputs, despite copying them from the Norton handbook. One cryptic response was “TOO MANY PARAMETERS”. Another was “UNKNOWN SWITCH”.

Yow, sounds very threatening! But in the end, the problems and the fixes were very simple. As to parameters, the problem was simply that you were to identify the disk with a number (usually “1”), and not “Disk 1” or such. If you spelled out “disk”, this amounted to adding “too many parameters” to the expected disk identification. Similar problem and solution for “unknown switch”es: I left out a blank space at a critical point, and the G disk program refused to recognize the “switch” (command).

Here is the discussion that finally settled this for me:

http://forums.pcpitstop.com/lofiversion/index.php/t111634.html

The first five or six commentators seem just as confused as the guy who was having the “parameter” and “unrecognized switch” problems. FINALLY, the last guy knew that it was just a matter of mis-typing the command.

Another issue involved converting the extended drive on the DC5000 over from FAT32 to NTFS format, as to match the format on the C drive which the XP programming installation forced. (NTFS is supposed to be a better format than FAT32, so I had no objection to it). I did the Google research and learned the XP command to convert an extended drive (i.e., anything on your hard disk that’s not the C drive), and punched it in. And saw an unfriendly response: Format not available for this volume. WHAAAAAAAAAAAAA ???? Well, I copied the response and punched it into Google, and read the following technical discussions:

http://forums.pcpitstop.com/lofiversion/index.php/t111573.html

http://www.technologyquestions.com/technology/windows-xp/66641-unable-convert-ntsf.html

If you check these out, you will have to cut through a variety of guesses and theories until someone finally spots the error: my error, and the people who wrote in to these web sites, simply misspelled “NTFS” as “NTSF”. DUHHHHH!!!!! Thus chastened, I went back, typed in the proper spelling, and the D drive converted over to NTFS without problem.

It was that kind of weekend. Clumsy, humbling, frustrating, way behind schedule; but in the end, the machines were still humming. It was that kind of weekend; for some of us, it’s just that kind of life.

Personal Reflections ... Technology ...

I was reminiscing the other day about the cars that I used to drive. The one that I had the longest was a 1974 Plymouth Duster. My mother bought it new for me in early ’74, and I finally got rid of it in early 1988. Somehow I survived fourteen years with that car. And I am most grateful for surviving those years. That car would do the craziest things, things that could have cost me my life. Luckily — VERY luckily — the car pulled its tricks in relatively tame circumstances.

Just what did this car do? Well, it stalled a lot. And not just at stop lights. It once stalled on the Garden State Parkway while doing 55 MPH. I was able to pull over safely since it was on a Sunday night. But had that been in heavy traffic on a weekday afternoon — well, I don’t want to think about it. What else? Well, my Duster had something call torsion bars. They were part of the suspension system. I learned about them while driving with some guys out on a back road near the Delaware River around sunset. Boomp! What was that? And why is the car driving so funny now? The answer was that the right torsion bar had cracked and failed. And without it, you couldn’t do more than 10 mph without losing control. It was a long night getting home, and a couple of days getting a new torsion bar installed (with the help of one of the guys).

Then there was a cold January day on a photo road trip to middle New Jersey, where the car was doing just fine. Until it decided not to start at all; no amount of cranking with the pedal floored did any good. A ballast resistor suddenly failed. And my brother had to come to the rescue with a tow chain, which came unhooked in the middle of downtown Newark, NJ on Route 21. I’ll never forget standing in the middle of the road at sunset with a line of blocked cars honking, big office buildings on either side, waiting while my brother and my friend got the chains re-hooked. Somehow we got away before the cops could hassle us.

And then there was the time that the floats in the carburetor went, causing the car to stall during a left turn. Not every left turn, mind you. You just never knew when you’d lose all power during a left turn. Another time, the carburetor came loose while I was tooling along in a 40 mph zone, heading for work. I hit a bump and poof, red lights and a stalled engine. I called up the gas station guy who lived next door to my family, and walked the rest of the way.

I still don’t know how I nursed 14 years and 125,000 miles out of that confounded Chrysler contraption. I do remember spending a lot of time under the hood and sometimes under the frame. It was a lot easier to work on cars back in those days; you can’t get to anything on a modern car. But you were always working on your car back then; there was something to tend to just about every weekend, even if there wasn’t an emergency breakdown. I got to know a lot of auto parts stores back then. Even a radiator place that supposedly didn’t sell to the public (but they gave me a break).

Today I’m driving a Toyota Corolla. Knock on wood, but so far it’s acting like — like a Toyota Corolla. Nothing much goes wrong, so long as it’s taken to a good mechanic every 5000 miles (where I walk out a hundred bills or two lighter). Almost everything under the hood is now a mystery to me. But it starts up and runs, and keeps on running.

The overall intent of both cars is about the same: basic transportation. But so far, the Toyota seems to provide it with much less drama. Sometimes I almost miss getting my hands all greasy and sweaty with a socket wrench, or standing at an auto store counter telling the guy that I need a whatchamagizmo for a ’74 Plymouth one-ninety-eight six cylinder. And it’s worth a laugh remembering those crazy breakdown situations, and what I had to do to get out of them in one piece (and without going bankrupt, given that we didn’t have too much money back then). But here in my old age, a Toyota is the right car for the times. Thankfully, they don’t build ’em like Chrysler-Plymouth used to!
