It’s not clear how this procedure works. In the article, it mentions that people entered with borrowed cards are a problem, as they are not paying the membership fee. Merely scanning the membership will not catch borrowers. How can this stop the use of borrowed cards? At the checkout register, you can flash the borrowed card, but then use any Visa card to pay the tab.

When my daughter remodeled a repo house that she and her husband bought, she has a problem that her contractor couldn’t solve. The kitchen ceiling was sloped and one of the hanging pendant lights has to have a threaded tube had to be shortened to make the two lamps be level. Looked that a normal 3/8 machine threaded parts had to be cut off and be retapped. Tried to tap and they would not fit without binding. Finally found that thread was a 1/8 in pipe and I realized that this was a hangover from the days if pre-electric gas lighting. Go figure!

It all has to do with the with the separation of the light source and the viewer. As a young graduate engineer, I remembered looking out the plane window at the shadow of the plane on the ground as we landed. It was always surrounded by a bright area. My initial thought was that the plane was somehow diffracting the light, till I realizes that in that area there were no shadows visible because I was in line with the sun.

I have struggled with the problem of old slides, looked at inexpensive slide duplicators and was not satisfied and here’s my quick and dirty method. First a bit of background. I’m 86 years and have been using an Exakta SLR since the late 50s. Took slides of our 4 kids until my wife complained about the hassle of looking at them, and insisted that on switch to prints. What to do with those old slides if the kids?
My kids are confirmed cell phone or I-pad users, so I didn’t have the need to make ultimate resolution copiers. They would only use an iPad ro look at them. I set up my old slide projector, a LaBelle, that could holf 175 slides and projected them onto a piece of foam care, which is grainless and dead white to a size of about 24 inches wide. Set my Canon Rebel 4ti on a tripod and photographed each slide in sequence. Experimented with aperature to get the best resolution and went to work. My biggest problem came about with portrait format mixed into landscape formats. I ran through all slides, photographing the landscapes first, then re-orientating the camera and reshooting only the portrait ones. This used the full area is the sensor. The only downside is that the file resulting numbers in the sequence taken, all the landscapes first and then the portraits. On an iPad, they look great, and that’s the way the kids will,ever look at them.
The use of foamcore is critical. First attempts with a glass bead screen and them a ridged silver screen wert ruined because the granularity was evident in the pictures. The projected size was about 24 inches wide and I adjusted the camera zoom to about midrange and distance the camera distance to the screen for best resolution.

Since most people get a mortgage to buy a house, the thing that counts is how much you can afford for a monthly payment. I ran a quick program which calculates the monthly payment for a house which sells for $400k, requiring a $100k down payment. If the interest rate is 4% for a $300k, 30 year mortgage, the monthly payment is $1432 per month. If the interest rate drops to 3%, the payment drops to $1265. I can now afford to go up a bit in the monthly payment to get a more expensive house. How much? With a bit of calculation, you will find that for your initial amount of $1432 per month, you could now afford a $340k mortgage.

There are a few advantages of sous vide over reverse sear. For one, it's easier. You can leave it in the sous vide until your ready to sear it. With reverse sear you have to pay attention to when it reaches the right temp. If you're distracted for a few minutes you can overcook the steak. Another big one for me is that when the reverse sear gets to 125 degrees in the middle, the outside will be much hotter and cooked more. with the sous vide it's perfect all the way through. Also, as I documented in a previous comment, with sous vide you can prepare several steaks at different levels of doneness and have them all ready at the same time.

I’ll admit the downsides of reverse sear. It does require that you pay attention, and the exact cooking time depends on the thickness of the steak. Also, you can only achieve one level of doneness if you are doing a steak dinner for a group, or can figure out the timing so that they all come out at the same time. This also puts timing restraints on the preparation of side dishes, as they have to be ready when the steaks are.
However, the same thing holds for the sous vide method. The doneness depends on the water bath temperature, and if you want different levels of doneness you need different water baths. One for rare, medium, etc. You can’t sous vide them ahead and hold them, unless you keep them in that water bath. If you try to chill them and then reheat them later, you have to reheat them in a bath that is no hotter than the lowest temp bath you used for the group of steaks. I suppose that this could work; well done would have the same internal temp as a rare steak. People that would ask for a well done probably wouldn’t notice the difference anyways😀

I have been having a conversation with one of my sons about the merits of sous vide versus reverse sear method of cooking a steak. The reverse sear involves oven cooking at 275 deg until the internal temp as measured by a sensor put in the center of the meat. The meat is seasoned with salt and pepper and placed on a rack. When the internal temp reaches 125, the steak is removed from the oven, wrapped with foil and left for 10 minutes. The internal temp will rise to about 130, or medium rare. It is then seared in a very hot cast iron skillet with a small amount of fat for a minute or so on all sides. The result is a steak with a good crust and a more or less uniform pink color.
One difference is that the reverse sear causes the steak to be dry on the surface as all the juices are dehydrated and their contents left there. This results in a fabulous crust. In the sous vide method, those juices are captured in the plastic bag and discarded. You dry the steak with paper towels as it won’t sear unless it is dry.

My son swears by the sous vide and has done a large prime ribs with it. He has a large pellet fired grill that he uses to sear, and the result is perfect. One of these days, we will have a cook off with blind tasting of steaks and compare the results.

I’m surprised nobody has mentioned Muir Woods, which is just north of SF. Giant redwoods, some a thousand years old, and the tallest trees in the world.

I’m surprised that the book “Eats, Shoots & Leaves” hasn’t been mentioned in this discussion. It was popular a decade ago and discussed the issue of how the use of commas could completely change the meaning of a sentence. It also discussed the use ”Grocer’s apostrophes” such as “Apple’s $.99 per pound” has proliferated. It’s written in a humorous vein and is quite entertaining.

My dad, who was a mechanical engineer at UC Lawrence Labs which used the metric system, told me about a request from the Livermore lab which asked that only English measurements be used when transferring specs. The request was satisfied by referring to flow rates in “Firkins per fortnight.”

Engineering is the economic application of science. One of my favorite sayings is: An engineer can do for a do for a dollar what any damned fool can do for a hundred.

Sounds like you learned the same bit of doggerel that I did. It goes: How I want a drink, alcoholic of course, after the heavy chapters involving quantum mechanics.

One solution to to landscape/portrait orientation would be to put all the slides in the carousel with the same orientation. It will be easier, I think, to rotate the image back to proper orientation in LR or PS or whatever you're using. Since I have slide shows in carousels in the order I made decades ago, I'd want to keep that order.


Yes, it would be preferable to maintain the original order, but the downside is that you will have to set the field of view in the camera large enough to cover both formats. When your camera is in the landscape orientation, a portrait slide will only use 44% of the available camera pixels. At the same field of view, a landscape slide also uses the same 44%,unless you are willing to change the camera zoom. If you have pixels to burn, it might be a reasonable compromise. I think that you are only going to view the results on a computer screen it might be ok.

If you go with projection onto a screen and photographing the with your camera, don’t use your old projection screen. Use a piece of foamcore instead, which is a 1/4 inch piece of foam covered with a white paper. It os available in sheets about 2 by 3 foot sheets. No texture was evident in the results. The camera, a Canon T6i with a 18-135 zoom, was on a tripod with a remote release and the projector was along side to minimize any parallax distortion. I tried using my old glass beaded screen and a newer solver screen and the texture of the screen was very evident in the photos. The only problem I had was that I used to take slides with both landscape and portrait orientations. My solution was to go through a cartridge of 150 slides and photograph the landscape versions first and then reorient the camera and catch all the portrait versions. My projector is a LaBelle that handled the slides stacked in a vertical tube. To do a 150 slide tube took less than 5 minutes. The worst part of the “two pass” process was that the resulting images were out of order, with all the landscape shots first and then the portrait ones next. I did a number of test shots and found that the bear results were in manual mode at f-11

Two golfers were about to tee off on the 9th fairway when a naked woman suddenly dashed across the fairway and disappeared into the bushes. 15 seconds later, two guys in white coats and nets ran across after the woman. After another 10 seconds came another guy in a white coat carrying two buckets full of sand.

One of the golfers turned to his caddy and asked, “What was that all about?” The caddy replied, “That woman is a patient at the mental hospital, and she occasionally escapes and they have to chase her down.” The golfer replies, “OK, but what about the guy with the buckets of sand?” The reply came back, “That’s his handicap, he caught her last time.”
