Today I Leaned: Chickpea *is* Garbanzo Bean

 I've been gifted several cans of garbanzo beans, and I never really looked it up. So imagine my surprise that they are also known as chickpeas, one of those protein-rich beans that can be made into a variety of things, and tastes better than soy. 

I think I can mix up the cans I have with some microwaved veggies and some meat to make a sorta casserole, once I figure out how to make a savory but not too salty sauce.

Today I Learned: Portable Generators are NOT Standby Generators

You know portable generators... size of huge toolbox / large wheelbarrow (about 200 pounds), add fuel and it can power up your home for a short time... Costs about 1000 USD. 

Turns out the "short time" is 8-12 hours, which is the run-time based on their fuel consumption and their fuel tank size. 

And you are NOT supposed to run it past 50 hours (after which, you HAVE to change the oil). Failure to do so will likely damage the engine.  

Given that most of these only runs for 8-12 hours (based on fuel consumption and fuel tank capacity) that should not be a problem... Unless, of course, you were in a multi-day blackout like the one Texas endured not too long ago in 2021, and you can't really be bothered to change the oil when the fuel ran out at night. 

The solution is a "standby generator", which is quite a bit larger, and comes with a much larger fuel tank... and they are actually diesel, not gas or LNG. They are obviously more expensive, but they are designed to run for days at a time.

Today I Learned: What is a "skort"

Skort -- (noun) combination of "shorts" and "skirt"; athletic wear worn by female athletes, usually reaches down to mid-thigh, but also with wrap-around panels in the exterior covering the shorts so it resembles a short skirt.

Today I Learned: Shingled Magnetic Recording Hard Drives

Sometime during 2020, hard drive vendors have slipped SMR (shingled magnetic recording) drives into the consumer line of hard drive, that used to be only CMR (conventional magnetic recording). 

What's the difference? SMR writes overlapping tracks, instead of discrete tracks like in MMR. The result is MUCH higher data density, but much worse performance due to the need to micro-position the heads to read those overlapping tracks. With much higher density, what used to require more platters can now be made on fewer platters, reducing overall costs... as the expense of performance... something regular users likely would not notice. 

Previously SMR was only used on the VERY largest drives where they were advertised as archival grade: you write to it and mainly to store them rarely access them. But slipping them into the regular consumer channel means some people are buying them expecting them to perform one way... and they are not getting it. And some users are crying foul. 

Buyer beware... figure out if you have SMR or CMR spinning drives. 

Or just buy SSD.
