Saturday Stew: Clearing out the Groupatwos before Pesach

Written By: cahwyguy - Sat Apr 12, 2014 @ 9:18 am PDT

Observation StewIn the Talmud, there is a learned Rabbi who opines that groupatwos are to be considered Chametz during Passover. Luckily, this week was so busy I accumulated a bunch of groupatwos. So let’s get that feather and that candle and get them out of the links list before Passover starts Monday night:

Saturday Stew (Belated): Transportation, Science, Streets, and XP

Written By: cahwyguy - Sun Apr 06, 2014 @ 6:23 am PDT

Observation StewYesterday was a crazy day, and I didn’t get a chance to post my normal Saturday Stew. Luckily, stew can cook a little extra without going bad, so here’s something tasty for your morning. Note that I left a few ingredients at work — I’ll save them for next week, and you likely wont’ miss them here.

A Matter of Time: Mail, Mobile Phones, and Mainframes

Written By: cahwyguy - Fri Apr 04, 2014 @ 12:23 pm PDT

userpic=anniversaryToday’s lunchtime news chum collection comes to you courtesy of Timex, for it is all about time and anniversaries. This is appropriate, as NIST is about to introduce a new, more-accurate atomic clock.

  • Mail. This week marks the 10-year anniversary of Gmail. Many of you may remember life before Gmail. I certainly remember the days of command-line email — /bin/mail, mailx, and numerous other mail readers (I was particularly fond of using email within emacs). Then we moved to nicer email clients, such as Pegasus, while the Corporate folks dealt with Outlook and Notes. Web-based email, at that time, was horrid — limited storage, limited interfaces, limited searching. Google changed all that with gigantic limits and great interfaces, all for the cost of your soul (no, that not right) your privacy (getting closer) the ability to search through your mail and sell you stuff based on it (that’s the ticket). Gmail isn’t perfect — there still isn’t the ability to work with digital certificates and encrypted mail. Hopefully we’ll get that. Otherwise, Gmail has become such a juggernaut (especially when combined with Android) that it is unstoppable.
  • Mobile Phones. Speaking of Android, this week is also the 41st anniversary of the first mobile phone call. Talk about life-changing devices. No longer can you hide anywhere — being incommunicado is now unthinkable. We’ve got from only a few having cellphones to everyone having them with them 24×7. In fact, you now no longer have just a phone, but an entire miniature computer with you. As evidence, I just added a page to my Passover Hagadah to remind people to turn off their cell phones; yet another form of escaping from slavery!
  • Mainframes. This week also is the 50th anniversary of the IBM 360 mainframe. Now, many of you youngsters (hey, you, get off my lawn) don’t even know what a mainframe is, so bear with me. Back in the 1950s, computers were one-shots — built for a specific purpose, for a specific task. Some smaller computers (such as the IBM 7090) started to come in, but they still often used plugboards and were unsuitable for the enterprise. In the 1960s, IBM introduced the 360 line — a range of computers, all running a common OS (at that time, OS/MFT) with common machine instructions that were extensible. Business could now afford computers. I programmed on a number of 360 systems: the 360/50 at LA Unified, the 360/91 and 360/75 at UCLA, and later, the 370/3033 at UCLA.

It’s the Littlest Things…

Written By: cahwyguy - Thu Apr 03, 2014 @ 12:22 pm PDT

userpic=observationsToday’s collection of lunchtime news chum stories all have to do with the littlest things having big effects:

  • High-O Silver! Recently, my wife picked up a new antibiotic gel at the pharmacy — an over-the-counter colloidal silver creme. I thought nothing of it (other than to try it and see it worked well) — after all, there are people who use colloidal silver to fight infections, although it has the side effect of turning your skin blue. Additionally, according to numerous studies, consumers may benefit from the silver specks’ ability to inhibit the growth of bacteria, fungus and other microorganisms, including disease-causing Escherichia coli and Staphylococcus aureus. So, I was intrigued by this Discover article about the new silver antibiotic gel — it seems that it contains silver nanoparticals that may harm humans and wildlife. The problem is that silver nanoparticles’ tiny size allows them to enter parts of living things bodies that other molecules can’t reach. This can damage the inner workings of cells and inhibit protein production.  And of course, being stupid humans, we’re just tossing this stuff into the environment, along with plastic nanoparticles, gold nanoparticles, and copper nanoparticles.
  • Battling the Bulge. Everyone has heard, by now, of the various bariatric surgical approaches for weight loss. Two of the best approaches are the Roux-en-Y gastric bypass operation and the vertical sleeve gastrectomy. One might think that these approaches work by reducing the size of the stomach, and thus reducing the amount of food one can eat and/or absorb. But if you think that, you would be wrong. There’s some new research on how obesity surgery really works, and it is astounding. It appears that these surgeries actually work by setting in motion a cascade of signaling changes in the gut and elsewhere. Those changes, in turn, reshape the mix of gut bacteria in ways that appear to turn up metabolic function, lipid metabolism and signals that tell the brain it’s time to stop eating. Researchers have already observed that certain bile acids circulate more copiously in the guts and blood of patients in the wake of bariatric surgery, but could only guess at why. They also have observed that the community of bacteria colonizing the guts of obese patients changes in the wake of bariatric surgery. Researchers just found that that one link between these two changes is a genetic “switch,” or transcription factor, called FXR. Increased bile acid unlocks FXR, which improves metabolic function directly. But improved FXR signaling also promotes the growth of gut bacteria that help regulate fat metabolism, and suppresses gut bacteria that is linked to weight gain and metabolic disturbance. The next step is to figure out how to create the FXR signalling through medicine, not surgery.
  • Concrete Isn’t Forever. Most of us see something made of concrete, and we think “permanence” (well, I also wonder about the water trapped in the structure). But all of our concrete isn’t permanent, and that’s creating a problem. Here’s the scary headline related to this that caught my eye: Concrete-Dissolving Bacteria Are Destroying Our Sewers. The problem is that, within the sewer system, one set of microbes emits hydrogen sulfide, the gas that is also responsible for raw sewage’s unpleasant smell. This gas fills the empty space between the top of the pipe and the water flow. Another set of microbes living in this headspace turns hydrogen sulfide to sulfuric acid, which eats away at concrete, leaving behind gypsum, the powdery stuff you find in drywall. This turns the sewer pipes into wet drywall. Yuk. That’s worse than Orangeberg piping. The current solution is to put plastic liners into the concrete pipes, a process that is almost as expensive as digging them up entirely. A better approach might be to embed anti-bacteria in the concrete (but that can build resistance). Microbiologists are instead thinking about how to tinker with the water systems and DNA sequencing to create probacteria — bacteria in the water pipes that are harmless to humans (so they say) but can manage the sewer bacteria.
  • [ETA] Bugs from Birth. Here’s a P.S. item from Andrew Ducker on how the birth process was designed to colonize us with beneficial microbes that help keep the bad ones out. The implication of this is that, as more and more women opt go to the Caesarian route for convenience, we are entering life less prepared with the good stuff we need to get us started. As the article notes, “the founding populations of microbes found on C-section infants are not those selected by hundreds of thousands of years of human evolution or even longer.” In other words — we are too safe for our own good.

Scientists like to say that this is a bacteria’s world, and we just live with it. After all, humans carry more bacteria cells than human ones, and without bacteria, we couldn’t live in the world. In fact, small microbes now are believed to be responsible for one of the greatest mass extinctions on earth! We need to think more about our indiscriminate use of antibiotics,  and the impacts of our growing use of nanotechnology that we don’t fully understand.

Observation StewWell, it’s Saturday, and you know what that means — a tasty news chum stew of the leftovers that couldn’t make a coherent dish during the week:

OK, so it’s a skimpy stew.

Problems From The Past

Written By: cahwyguy - Fri Mar 28, 2014 @ 11:38 am PDT

userpic=headlinesThis has been a busy week between work, headaches, our daughter being home, and planning for a new phone (acquired yesterday). Still, a few articles caught my eye, and some of them even themed. In particular, this set of items, all dealing with things we’ve seen in the past:

Saturday Stew: From XP to Exes, from New Coins to Old History

Written By: cahwyguy - Sat Mar 22, 2014 @ 6:52 am PDT

Observation StewIt’s Saturday, and that means it is time to clear out the links for the week. This has been a busy week, with a major recorganization (which was more of an org chart relocation) at work (means loads of “all-hands” meetings full of sound and fury, saying little), loads of documents to review, and loads of stuff to catch up on. As a result, I rarely got time to look at the news over lunch, and have only collected a few things that didn’t them. Let’s get to them:

  • The Death of XP. My RSS feeds are full of dire warnings about continuing to use XP after support stops on April 8. As it is, I have three XP machines at home: two that are just sitting, turned off, and one that is used solely as a print server. Still, I am thinking about replacing it, and two articles caught my eye. The first looks at 3 Linux alternatives to upgrading Windows–I’d seriously think about upgrading at least one to Linux if it can work as a print server on a Windows network. The second talks about how Microsoft is offering special deals of $100 for those upgrading from XP. With some Windows 8 machines in the $200-$300 range, this brings systems to the noise level.
  • Challenging Coins. Two interesting articles on coins this week. The first talks about the new £1 coin Britain is introducing. It will be 12-sided, and incorporate different-colored metals, for a faux gold and silver look, instead of the mostly copper blend now in circulation, and boast a high-tech anti-forgery feature used in paper money. It looks like it is complicated to make. Even more complicated is a new domed collectable coin being made by the US Mint: a domed coin commemorating baseball. Evidently, it was very hard for the mint to manufacture, and took a bit of experimenting to get right. What’s interesting here is reading the comments — there are a large number of people who do not understand that collectable coins and stamps make the government money.
  • Training For It. About a week or so, I had set aside a story about a railroad club in Orange County that had their trackage stolen, intending to send them a little something. Turns out I wasn’t the only one: the club has received thousands of dollars in donations. A nice reminder that there are a lot of good people in the world.
  • Bad Design. Here are two articles about some bad designs. The first is about a new device you can slap on a milk carton–it uses nanotechnology to indicate visually if the milk is good or bad. So what’s the problem? According to the article, “red” is good, “green” is bad. This is the opposite of how red and green are nomally used in interfaces, and I predict people will get sick from the “green is good” hardwiring. The second is about golfing: it appears that titanium clubs striking rocks can create sparks that start brush fires. Perhaps they should give golf clubs to people on Survivor.
  • Out of This World. I’ve had this article sitting for a few weeks, but nothing seems to want to pair with it. Baker is a dying town — once home to the largest thermometer in the world, it is now slowly fading into the desert. But the owner of Alien Jerky wants to change that — and one way is to build a flying saucer shaped hotel.
  • The Jewish Valley. I’m into history. I’m into Judaism. So naturally, I’m into the history of Jews in the San Fernando Valley. Many years ago, Rabbi John Sherwood and I even toyed with the idea of writing a book on the subject. So here’s an interesting article in that vein: it explores the early days of the Valley Jewish Community Center, which became the Conservative synagogue Adat Ari El. This is the synagogue that was the parent of most Conservative synagogues in the valley, just like Temple Beth Hillel was the first Reform congregation and was essentially the parent of most Reform congregations in the valley.
  • Marital Success. What makes a successful marriage? Is it your partner? It is living together before you get married to work out the problems? Is it “murder frequently, divorce never?” According to this article from Atlantic, it is being mature when you get married. An exploration of the science of cohabitation shows that the older people are when they make their long-term commitment as a couple, the more likely that couple will stay together. The study found that individuals who committed to cohabitation or marriage at the age of 18 saw a 60 percent rate of divorce. Whereas individuals who waited until 23 to commit saw a divorce rate that hovered more around 30 percent. I got married when I was 25, and next year we will have been married for 30 years. As they say, you do the math.
