Calling The Next ‘Xbox’ ‘All-Digital’ Is Stupid — What They Mean Is ‘Solid State’.

I have never owned or even used an Xbox. Though I started programming in 1969 — or maybe because of that — computer games have never held any appeal. Yes, sure I have played a few and maybe written some rudimentary gaming code, in the 1970s, just to make sure I could do it. But, that is the extent of I and my intersection with computer games.

But, I do KNOW that all Xboxes, from Day 1, have all been DIGITAL. No, no part of it was ever analog — i.e., the opposite of digital.

CD/DVD drives maybe mechanical BUT they are 100% digital — as the ‘Ds’ in their names signify. ‘D’ for digital.

What these folks are trying to say is ‘SOLID STATE’. No moving parts. Everything electronic — no mechanical components bar the BUTTONS.

If you are a regular reader you will know that I always maintained that Dr. James Eakin, who alas passed away in August 2014 (way too prematurely), was, indubitably, THE BEST eye doctor in Central New Hampshire. With Jim’s passing we were in a lurch. We all went to Jim for our eye care (though I had to go somewhere for my bionic contacts). We tried a ‘local’ optometrist, up here ‘in the Lakes’, and was NOT happy. I had also got very disillusioned with the ‘fancy’ Manchester eye care place that saw me for my contacts — the only impressive thing about them being the outright audacity of their bills.

Deanna asked around, using her reach on Facebook, and heard about “Capital Vision Center“. We have now been there twice. Once in February for Deanna and yesterday, April 5th, so that Teischan (10) could get contacts. Both times we saw Dr. Baylus and he has impressed me, immensely. Given my dodgy eyes (despite my “Eagle Eyes” nickname) I am no stranger to eye doctors and I am rather particular. I have seen specialist in legendary Harley Street (in London) and Boylston Street (in Boston). Well, I am going to go see Dr. Baylus next. We have had a few conversations, about eyes, and I like his style.

I think this is the Digital Phoropter he uses. I could be wrong. It is pretty similar to this. Click to ENLARGE.

PLUS, they have ALL the latest technology — machines that I have only seen in Boston (though the place I was going to in Boylston St. had some of these machines 15 years ago). They use Digital Phoropters. That is so neat. The old analog phoropters, though visually and mechanically appealing, always seemed way too complicated for what they were trying to do. I would often have this conversation with eye doctors. Standing there adjusting all those knobs and sticking external lenses into holders just seemed so inefficient. Love the concept of the digital phoropter (and I am sure they are not cheap). I also think that they probably can be made to do more than they are currently used for — e.g., I am sure that they, with a bit more technology, could automatically, come up with the optimum prescription for your eyes.

Anyhow. This place is impressive and Dr. Baylus, from what I have seen so far, knows his stuff. I am not sure that I am willing, as yet, to pass on Jim’s mantle over to him but he is the only one in the running for now.

A beautiful example of an old analog phoropter, from Wikipedia, if you had no idea what I was talking about. Click to ENLARGE and goggle. I am going to check ebay to see how much an old one is. Would make a real neat wall hanging.

The Ozeri Gen II (ZB011) Digital Bath Scale (With BIA) That I Adored Goes On The Blink. I Am Bummed.

It Sure Is Cold. I Vetoed My 5°F (-15°C) Threshold …
>>Jan 24, 2013.


The last two days have not been good when it comes to electronic equipment. Not sure whether it is a coincidence to do with the ‘instant’ heat wave we are having. Thursday night my workhorse PC blew up! Much to Deanna’s amazement I did not go off the rails — mainly because I had taken the precaution, years ago, of having a 95% the same, backup system, pre-configured and ready to go.

The next morning, as is my wont, I weighed myself. Scales worked fine. I then went for my run. When I came back I hopped on the scales again because it amuses me to see how much water I have expended during the run. I do that most days too. So nothing new. Same routine.

The scales went ballistic! Told me I weighted 420 pounds! I wish. I would write a book about that. The damn scales were going crazy. Numbers rotating on the display like non-stop.

I removed the batteries and re-seated them. It was still demented. I tried again. Tried to rest it. Then it started saying that my batteries were low. As it happened we happened to have two spare batteries — and it takes those round, flat batteries as opposed to AA, AAA or 9V.

Still won’t work. Now it won’t register a weight. It will give me all my stored information but when I stand on it it displays NADA.

I am not amused. I loved those scales. I sang their praises.

They have a 1-800 number. That is a joke.

Checked with Amazon. I had bought them in January. So the normal return window has expired. Yes, I can still return it for a partial credit. I only paid ‘$20’ in total for these scales due to some Amazon promotion. So in the end not worth bitching too much.

But, Ozeri — I would never buy one of your products again.

Deanna has found a few possibles … in the $40 range. Given my diet regime I do need to keep track of my weight. So … yet another expense.

A pox on Ozeri.

My Ozeri Gen II on our bathroom floor.

My Ozeri Gen II on our bathroom floor.

As I talked about in my earlier post I ordered this digital scale because the old, analog one we had was obviously wrong. We have since worked out that it was about 6 – 8 pounds out! Then I remembered. I had bought it because I liked what it read.

We have had the Ozeri for about 2 weeks. I love it, though it tells me, daily, that I am heavier than I would like to be. It is uncompromising and with its decimal readings you don’t get to round up or down. It is as it says.

But, indubitably, the best $21 I have spent in a very long time — since Amazon still gave me free shipping even though it was under $25, and for a change, I wasn’t ordering anything else.

It is $39.95 on Amazon today. Not sure how I got it for $21. It was on sale for $29 that day.

As I had suspected it does ask you to enter your age, height and target weight. It uses that to identify you, it being able to identify 4 separate people based on the target weight specified.

My 21.2% body fat ratio from few days ago. I think it might have gone dowin since.

My 21.2% body fat ratio from few days ago. I think it might have gone dowin since.

That you enter your height means that it can work out your body fat, or Body Mass Index (BMI), by just dividing your weight in pounds by your height in inches. But, it insists that it does not and instead does so by measuring your Bioelectrical Impedance Analysis (BIA). I was skeptical, and as a professional cynic, I still am. But, from day one it insisted that my Body Fat Ratio as it calls it was good. I was impressed. For my advanced age, according to its handbook, my Body Fat Ratio should be in the 11 to 22 range to be ‘Healthy’. 22 – 28 is overweight and 28-80 is obese. When I turn 60 in a few months I can have a 13-25 range and still be in healthy.

Day one it had me a tad over 22. I was cool. I knew I was overweight. But, as I started to lose weight it came down. In a few days I was down below 22. But, per this scale it was impossible to shed even a pound. I went for about 4 days at the same weight. Then slowly it started to agree that I was losing weight. The decimal readings are unforgiving. So, if I am 182.3, I am 182.3. Not 182 and I can go at 182.3 for 3 days. But it is also scarily precise. On Saturday after I had been shoveling snow for 90 minutes I weighted myself. I had not drunk or eaten anything since I had weighed myself before going out to shovel. It said I had lost 2.25 pounds! That is just dehydration.

Love the scale. It is a work of art too. So far so good. I will get myself properly weighted again soon as I can get a feel as to its readings.

I will keep you posted.

Laser reflector installed on the Moon by the Apollo 11 mission in July 1969.

I will readily admit that I lead a very sheltered life. Though technology was my life for nearly 35 years, I have never had a great desire to own the latest and greatest in technology. Just don’t like the hassle. So, by choice I refuse to have a smart-phone. I have an old-fashioned cell phone with no Internet access. Most of the time, like much of today, I didn’t even know where it was. I don’t have a pad and never will. It is enough that the kids each one. Though I try to stay conversant with technology, I can be very blinkered — my research and writing requiring considerable focus and discipline. So, I had no idea that they are looking at the possibility of using DNA as a storage mechanism until Deanna told me about it a few days ago. Alas, they are still only using synthetic DNA, not that I actually had known that they actually had a thing called synthetic DNA. 20 years ago there was a great proposal for a feasible, extremely high capacity data storage scheme for the world. [Remember, I did use to be at the cutting edge of large data center technology.] This plan is doable right now. Did you know that there are Laser Reflectors on the moon? There has been one on the Moon since 1969. There is at least 3 reflectors on the moon, carried there by Apollo 11, 14 & 15; Apollo 11 the one that carried Neil Armstrong to his historic walk on the Moon. [No, you won’t be able to shine your 2 tripe-AAA battery powered laser pointer at it. Sorry.]

The plan is very simple. Start shooting a powerful laser at the Moon and create a laser ‘Local Area Network’ (LAN) — ‘local’ always a relative term in networking. Then pump data into this laser and have it continually go around the Earth-Moon laser LAN. In reality we (even I) know how to fix, at least in theory, all of the perceived problems — security the paramount.

Well a technology that I had no idea about was Bioelectrical Impedance Analysis (BIA). Part of this could be because I try to stay clear away from all things to do with medical stuff. It is bad enough having to go to a doctor. Plus, I can honestly say that even though I have had most tests that can be done on a human performed on me — I have never had my Body Mass Index (BMI) measured electronically. I am amazed and in awe. I am fairly adapt at calculating BMI = weight in pounds/height in inches.

bmiscalesWell it looks fairly certain that our bathroom scales, which I bought at the local consignment store, Trudy’s, because I liked what it showed, has been misleading us. Maybe I am not 180 lbs, but more like 188 or 189. Bummer, though I really cannot lose any weight from my bum. It all has to come from other places. So, I now need to lose 20 pounds rather than 11.

So, the first thing I do when I get back from seeing the cardiologist was to start looking at new scales. [The visit was a total waste of time and will most likely cost me $180. Very nice guy. But, I think he is ill, very ill. I felt bad for him. He looked in much worse shape than me, and he is 20 years younger.]

I first researched analog vs. digital. People swear that new digital is more accurate, though I am skeptical. But, I checked Amazon. Was amazed how cheap digital scales were. Then I noticed that some claimed that they would automatically calculate BMI. In my ignorance, I assumed that you had store your height and all that the scale did was do the division for me. Wrong!

The scales use BIA, and you don’t even feel it. It measures the electrical impedance of your body tissues for an estimate of total body water (TBW). Your weight less TBW provides an estimate of fat-free body mass. The rest is FAT! It does all of this in milliseconds. Amazon likes me. So they ‘said’, electronically of course, that I can have a fairly fancy BIA digital scale, with free shipping, for $21. Plus, they give me a year to pay for it, interest fee. How can I refuse. So, I am now waiting for my new scales. Hope they work. Yes, I gather that if you are extremely athletic and muscle bound, the reading might be off. Well, I don’t have that problem.
