17” laptop for seniors

I wonder if this is the start of a trend… a 3 lb. laptop with huge screen and medium (2560×1600) resolution: LG gram 17″.

Could this be the perfect device for seniors? With eyes older than 50 years, 4K resolution on a 13″ screen is not all that useful.

Maybe this particular laptop isn’t the one, since it lacks a touch screen (I don’t need the convertible fold-over feature, but I don’t think I can go back to a non-touch laptop), but I’m wondering if it shows a future to which we can look forward.

As with other computers these days, I’m mystified by the small amount of RAM (16 GB) with which this thing is set up. My 32 GB desktop right now shows that 19.4 GB is in use. Google Chrome accounts for 6 GB. CrashPlan backup software is using 3 GB (it needs this if you have a lot of disk space to be backed up). Microsoft Edge is using 0.5 GB. Adobe Acrobat is virtuous! It has a bunch of big documents open and is consuming only 147 MB.

Given that processor performance has more or less stalled out I would expect a modern laptop to be available with 32 or 64 GB of RAM and 1-2 TB of SSD. A SanDisk 2 TB drive is $250 at Amazon. The 16 GB of RAM that LG includes is less than $100 at retail on Amazon. Why buy an expensive package, screen, and battery to go with a puny RAM and SSD?

Readers: Can bringing the weight down to 3 lbs. and the package size down to where 15″ laptops typically are revive the moribund 17″ laptop category?

Why aren’t all dishwasher detergents the same?

Here’s a conundrum… given that dishwashers haven’t changed in the past couple of decades and fundamental detergent chemistry hasn’t changed substantially since 1946 (source), why wouldn’t all dishwasher detergents have converged to essentially the same formula? Or maybe there would be three formulae: soft water, medium water, hard water.

Perhaps detergents actually are all the same, but there is money to be made in fancy packaging and convincing advertising? If so, why does Consumer Reports rate detergents on a scale from 19 (Cascade Complete Gel with Dawn; looks like Procter and Gamble might need to spend more time in the lab and less time making toxic masculinity commercials for its Gillette division) to 85 (Costco’s Kirkland Signature Premium pacs, which might be Finish Powerballs in disguise? Finish rates 83).

Maybe it makes sense that the eco brands such as Seventh Generation and Ecover perform badly. Or the Trader Joe’s absurdly cheap (about 1/3rd the price of Costco!) pacs aren’t great (though nowhere near as bad as that Cascade gel product, above).

But why wouldn’t similarly priced pacs from the bigger vendors all be formulated essentially the same? How is it that the folks who make Finish know something that the chemical engineers behind Cascade don’t know, or vice versa? Even products with similar prices from the same company performed differently.

[Separately, if Consumer Reports is right, you should never ever buy dishwasher gel. A Palmolive eco+ was a mediocre performer and all the rest fell on a spectrum of bad to worse. The top-end Costco pacs were the best performers as well as about 1/3 the price of the top-end brand name pacs.]

It makes sense to me that a Tesla and an Audi electric car will be different. But why should dishwasher detergents be? Everyone wants the same thing (clean dishes).

Gillette-compatible blades from Schick

In https://philip.greenspun.com/blog/2019/01/24/gillette-versus-dorco-shaving-test-2/ the one thing that seems to give Gillette a slight boost over the Korean-made Dorco blades is that flexible head on the Gillette handle.

What if one could buy third-party blades and put them on the Gillette handle?

Schick offers just such a product: Hydro Connect. I ordered some yesterday and will be offering a report!

(These seem to be tough to obtain from retailers, though it is easy to buy them direct from Schick. I’m wondering if retailers are afraid of getting entangled in litigation, e.g., “P&G’s Gillette sues Schick maker Edgewell over razor blade design,” which notes that “Procter & Gamble Co’s (PG.N) Gillette unit on Monday sued the maker of Schick razors for the second time in 13 months, seeking to stop its sale of razor blade cartridges designed to fit Gillette’s Fusion handles.”)

Gillette versus Dorco Shaving Test 2

Continuing research in response to the controversy over Gillette’s recent “toxic masculinity” ad campaign … (see Test 1)

Test 2:

  • two days of growth
  • shaving in the shower
  • Edge shaving gel
  • Dorco Pace 7 on right side of face
  • latest and greatest Gillette Fusion 5 ProShield with Flexball on left side of face
  • second shave for each cartridge (first shave was Test 1)

Results: Indistinguishable feel and capability of the two blade cartridges. Equal resulting smoothness of face on both sides. No nicks from either system.

Winner: Gillette by a hair(!), due to the Flexball (introduced 2014), which seems to reduce workload slightly.

[Bizarre: in their zeal to be the wokest of U.S. consumer goods companies, Gillette has neglected to be orthographically consistent with their only potential advantage over Dorco. Parts of their web site use “FlexBall” while other pages include “Flexball”.]

Renovate a 10-year-old Buderus gas boiler?

We have a 10-year-old Buderus GB142 wall-hung gas boiler that is suffering from myriad corrosion issues. The HVAC service folks recommend either dumping in $3,300+ for a “major renovation”, including replacement of the manifold and everything connecting to the boiler, or spending $15,500 (minus $2,750 in rebates under the poor-renters-should-subsidize-rich-homeowners political theory that prevails in Massachusetts) on a new 150,000(ish) BTU high efficiency system.

Does anyone have experience with these beasts? Are they worth fixing? Are we going to pay $3,300 now and then $15,500 a year from now when something else blows up?

Also, if we do decide to replace, Lochinvar or Bosch? (presumably we don’t want to go back into the Buderus money sinkhole, though on the other hand Bosch liked them well enough to buy them!)

Note that my glorious plan to replace this with an old-style standard efficiency boiler ($2,000 part every 20 years) seems to be impractical. It has to go into a small closet (no basement in this house due to architectural genius back in the 1960s) and the latest code would require fan-driven make-up air. So it wouldn’t be any cheaper than having a high-efficiency unit, according to the HVAC guys (and, for some reason, everyone who comes out to fix boilers on Christmas Day or crawl around in attics in July seems to identify as male; where is Hillary to address this injustice?).

[Separately, this is a great illustration of why official CPI is grossly understated for homeowners. The cost of maintaining a house has skyrocketed (very labor-intensive in a country where a worker can cost $30,000/year in health insurance premium before the first dollar of wages has been paid). The cost of paying real estate taxes has gone up dramatically (and about to go up 30% more in our town due to the approval of a $110 million school project (to renovate a school building occupied by 440 town-resident K-8 students!)). None of this is reflected in CPI (background) because they look at what we would pay to rent our house if we could find a landlord sufficiently passionate about losing money to want to buy it, maintain it, and rent it out.]

Update: Readers commented about what a rip-off the above quote was, for the Lockinvar 155,000 BTU boiler and associated fittings. So I got a competitive quote from a regular plumbing contractor who is excellent: $20.750. And I got a second quote from a friend’s heating guy: $15,000 plus or minus. Apparently this is the price in the Boston suburbs. We decided to go with the HVAC company’s $15,500 plan. Typical Americans can’t afford to live in America, is my conclusion. It just looks like we can because we’re using legacy infrastructure that hasn’t worn out or fallen down yet.

The best small kitchen knives (paring and utility)

Due to the fact that we think children will be poisoned unless they are fed organic home-cooked meals (not to mention sliced fruit and vegetable snacks offered every hour by their grandma), there is a crazy amount of cutting going on in the kitchen.

This has led to some practical research on knives. Here’s what I have figured out so far…

The Shun DM0700 Classic 3.5-inch paring knife seems to be popular for small fruit cut by small hands, but the Wusthof’s extra length is better for most things and the Wusthof is more idiot-proof with a rounded edge at the back of the blade near your hand. (I do love the big Santoku knives.)

[That there do not seem to be any good American-made knives, at least not at a competitive price, makes me wonder how the political debate about America’s biggest problems still contains statements of the form “We should do X the way that Country Y does X.” (example: New York Times story suggesting that the U.S. health care funding bureaucracy be torn up and rebuilt like Singapore’s so that we can cut spending from our 17 percent of GDP to their 5 percent) If we can’t compete in a straightforward market such as paring/utility knives, why do we think that we can do stuff that other countries do?]

Trek T80+ Electric Bike Review

I have been commuting to East Coast Aero Club, about 4 miles away, using a Trek T80+ electric bicycle. The machine was introduced in 2013 and discontinued in 2015 in favor of an improved design where the motor is in the bottom bracket. Fortunately the government assures us that there is no inflation because the new bikes cost $2800-3000 while the old one listed at $2100 (I paid $1300 for a closeout at Cycleloft in Burlington, Massachusetts). What does the beast weigh? Mine is an “XL” frame size and is about 52 lbs. using a bathroom scale. It seems to have started life as a Trek hybrid and was pimped out at a factory in Germany with the BionX hardware that is also available to enthusiastic hobbyists.

The bike comes with a 250-watt motor and a 250 watt-hour battery on the rear rack. Thus you can be a Tour de France rider for about one hour. Unfortunately this does not quite generate Tour de France speeds due to the fact that (a) I weigh 200 lbs., which I suspect is more than the typical pro cyclist, (b) the bike weighs about 35 lbs. more than a Tour de France bike (can be no lighter than 15 lbs.).

The bike is practical for commuting due to a sturdy rack on the back and a built-in lock that blocks the rear wheel from turning (so they can bend all of your spokes but not ride off with the bike). There is an included taillight on the back of the battery but no headlight, contrary to the magazine review cited below. There is a conventional Shimano 21-speed drivetrain that would be useful if the battery died but when commuting I find that the only gears I use are 4-7 on the largest chainring.

You control the motor by putting torque into the drivetrain via the pedals and setting a boost level from 0 to 4. With the boost on 4 your pushes on the pedals are magnified to the point that the bike will go 20 mph when you’re pedaling hard enough to go perhaps 8 mph. The electric boost cuts out at 20 mph by design. It also cuts out if you pull on a brake lever. Trek claims a range of up to 40 miles but that would be with flat terrain, a lightweight owner, and only partial boost. If I set the bike to max boost and go 10 miles over some slightly rolling hills the battery indicates a 50 percent charge. The charger is comparable in size and weight to a typical Windows notebook computer charger and therefore it would be quite reasonable to commute 20-30 miles to work, plug the bike in during the workday, and then ride back home on a fresh battery. The battery can be removed for charging, using the same key provided with the integrated lock, if there is no power outlet near where you park the bike.

What about exercise while watching the motor do all the work? It turns out that you will get as much exercise per minute of riding as on a regular bike. You will get only about one-third or one-half as much exercise as you would riding a regular bike to the same destination, however, because you won’t be riding for very long. The bike is so much more satisfying to ride and results in so many more destinations being accessible (e.g., 10-mile round-trip to the drugstore) that a typical owner should get more exercise than with just a regular bike. This is a substitute for a car rather than a substitute for a road or mountain bike.

Is it fun? Yes! I lent the Trek T80+ to an aircraft mechanic and he had a silly grin on his face as he said “This is what biking should be.” The bike is also nice on hot days because you are guaranteed to have a 12-20 mph breeze at all times.

What about the new stuff? It seems as though the 900-lb. gorilla of the bike world, Shimano, has entered the market with the Shimano Steps system, which is what Trek is using on their latest models. This may prove the point of Crossing the Chasm (that the innovators often don’t end up as market leaders because products that appeal to hobbyists and early adopters don’t necessarily appeal to the mainstream).

Happy Friday: Machine-assisted Fun

It’s Friday again and therefore time to put the Happy Helmet on.  What could be more fun for an American than wallowing in materialism and playing with machines?


This old gold dredge is on the road from Nome, Alaska to the small town of Council.

“>

MIT demonstrates its patriotism by giving us a four-day weekend for Patriot’s Day and I’ll be heading south in the airplane:  Saturday to DC (parents/sibs); Sunday to Williamsburg, Virginia (w/parents); Tuesday morning to Gettysburg, Pennsylvania (visit Matthew Amster, anthropologist, and Andy Wermuth, documentary filmmaker); Tuesday evening back to Boston (weather permitting; the forecast is a bit ugly).  On the way down I hope to repeat a fun flying experience from Monday:  asking the Logan Airport tower for a “city tour” clearance.  On the way to East Hampton we were able to fly down the Charles River at 1500′, right over Harvard and MIT, then made a right turn to the south in front of the tall buildings of downtown.  The only other aircraft in this space normally are the medical helicopters.


It is biking time again.  If you’re old and creaky and don’t like biking because it hurts your neck, back, and, uh, butt, I can recommend a recumbent.  It is as comfortable as sitting on your living room sofa except that sometimes you fall over sideways onto pavement (recumbents have smaller tires and therefore less angular momentum and therefore less resistance to tipping over).  You can pick them up new for $600+ and learn about them in alt.rec.bicycles.recumbent


If you live in the Boston area, I found a bike shop that seems vastly superior to the usual suspects (Wheelworks and IBC):  ATA Cycle on Mass Ave near Porter Square in Cambridge (http://www.atabike.com/).  They are very fast yet thorough with mechanical work.  They have some beautiful mountain bikes for trips through the Middlesex Fells, Lynn Woods, and other local spots.


When you get tired from biking and watch to relax on the sofa, this summer will bring the first crop of HDTVs that have enough holes in the shadow mask to display something like all the pixels in an HDTV signal (1920×1180).  Unlike with computer monitors, TV makers don’t tell you how fine the dot pitch can be.  The HDTVs sold so far have taken a high-res signal in but aren’t capable of producing anything other than a low-res picture because there aren’t actually enough distinct holes in the metal grille separating the electron gun from the phosphors.  Blowing $2500 on a Sony KV-34XBR910 so that you can enjoy every pixel of Laverne and Shirley will provide a much-needed boost to both the US and Japanese economies.


If you’re concerned that America’s maturation into neo-feudalism will tempt the serfs to try to take away some of your hard-earned wealth, consider an armored car from Lincoln, Cadillac, or Mercedes.
