Why are Hybrid SSD / Magnetic drives using the SSHD acronym?


I love technology and I love acronyms, but I hate it when they start reusing old acronyms. It was bad enough with "ATM" which we knew as "asynchronous transfer mode" in the broadband packet switching days of computer networking (especially here at Washington University), or short for "atmospheres" or automated teller machines (or the dreaded Adobe Type Manager). But another acronym recently came out for some pretty neat technology: hydrid solid-state and magnetic hard drives. These drives pair a small amount of MLC NAND memory (usually 8GB) with a much higher capacity, more conventional magnetic drive to create a drive with SSD-like performance, yet a large amount of storage (where the magnetic media does not need to be accessed as often either as its most used data is cached to the memory.) So this is a great idea, but they decided to come up with the acronym of SSHD (solid-state hybrid drive) to name this technology. The problem with any Linux geek like myself, is we know "sshd" is the daemon software for Secure Shell or SSH (typically the OpenSSH package in most Linux distributions) which allows encrypted remote terminal access or encrypted file transfer between Linux systems.

So when I started googling to see how people were using these new hybrid drives with Ubuntu or CentOS installations, I started getting all these results about OpenSSH server issues instead. Why did they pick SSHD as the acronym? You cannot even pronounce that as an acronym, and that is always much more fun! Why not HSSD which can be pronounced as "hissed" and is not used for much of anything? Why pick a acronym already used in the tech world?

BMI & BMR Calculator (Body Mass Index and Basal Metabolic Rate)

Image
My wife has been researching type 2 diabetes and recently checked a book out of the library which included a body mass index (BMI) chart much like the one pictured here. Whereas it is fairly easy to follow, I, of course, think it must be converted to an online calculator! However, when I checked the Internet, there were already a billion of them so I had to make one that was different. So my lovely BMI BMR calculator accepts either inches or centimeters for your height and pounds or kilograms for your weight and calculates not only your BMI, but also your BMR (basal metabolic rate) which determines how many calories you should consume! So I made a spiffy "all in one" healthy body indicator calculator which not only determines how underweight or overweight you are, but also tells you how many calories you should consume to maintain or improve your ideal weight.

Trying out the L'Ecole Culinaire Presentation Room restaurant

Image
We had been seeing the ads for the restaurant at L'Ecole Culinaire and since we live so close by we thought we would try it out. We had always enjoyed dining out at cooking or hotel schools like the CHIC in Chicago and the Statler at Cornell where we went to college. Since we still love to go out and eat here in St. Louis , we ventured over to their restaurant on the first day they were open for lunch. The first thing we noticed is that they do not have much parking! They really need to let patrons know where they are supposed to park. The restaurant itself is small but very well attended. There was one fellow who kept straightening all the centerpieces and place settings on the tables, and we always saw one or two student workers milling about. The lunch menu was small and the choices did not appear overly "gourmet". The special of the day was a bison burger stuffed with cheese, and other choices picked by my group included a club sandwich, a "margherita" pi

Not all Frosted Window Films are the same!

Image
We live in an older home with a lot of issues and one of them concerns our back door to our patio from our sunroom. The door has double paned glass on it, but unfortunately the seal has broken so you can see moisture collect inside of it. We decided the easiest way to "remedy" the problem was to cover the window with some "frosted" film so we did not have to see the moisture condensing between the panes. But the question was, what film? There are a bunch of them available so we had to select something to try on the door. The first place we tried was our nearby Lowe's store which had a bunch of Gila brand film. We selected what seemed like the typical adhesive based door sized  film that cost about $25 after tax. We thought it could not be that hard to put up and look nice on our door. So one day my wife ran out and purchased it at Lowe's and we commenced to install it on our door window. We made our own soapy water solution and followed the directions
