I am not a Twitcher, honest!
I can safely say that I have never Twitched, nor have I ever been tempted to become a Twitcher. But I will admit to being a bit of a birder, albeit only within the grounds of my estate in Annapolis, where seven bird feeders attract over thirty species of birds over the course of a year. So what exactly is a Twitcher, and should we be wary of them?
Twitching, which Wikipedia defines as “the pursuit of a previously located rare bird” is the preserve of fanatics who’s seemingly sole purpose in life is to seek and locate the rarest of rare birds and then proceed to tick them off a list. This, apparently gives them some sense of greatness in their world, but to most regular birders, Twitchers are frowned upon as being nothing more than inconsiderate glory hunters.
For those with Twitchering aspirations, there is some excellent advice to be found in Sibly’s Bird East book. While browsing this indispensible birders bible the other day, it dawned on me that a large portion of the advice for Twitchers could also be applied when we go hunting elusive Gremlins that are playing havoc with electrical and mechanical systems on board boats. This seems especially relevant for refrigeration and air conditioning, so, using the same advice given for finding rare birds, let’s interpret some points in order to help find those darn marine Gremlins.
1) “Most birders who find rare birds are looking for rare birds.”
Twitchers are actually looking for the unusual. If your mind is honed in to looking only for the obvious and normal, then you may overlook the possibility of something unusual going on. Strange happenings in complicated mechanical systems often occur only under a unique set of circumstances, and Gremlins can be hiding anywhere.
2) “An intimate knowledge of the common species is essential.”
You must have an in-depth knowledge of the system under investigation and its operational characteristics so that you can identify what is normal and what might be the work of a Gremlin. You must have a clear idea of what it should be doing before taking readings, putting a gauge set on, etc., and seeing what it actually is doing. In other words, don’t try and rationalize what you see without first having a clear understanding of what it should look like in normal operation.
We Are So Terribly, Terribly Sorry!
“We’re sorry.” “I’m sorry to hear that.” “Very sorry, but it’s out of our hands.”
We’re having to utter these sorry little phrases more and more these days, but not relating to any issues with our products. These are being made in response to reports of shipping issues, where damaged goods, lost or missing packages, inconvenience from signatures being required, and excessive shipping costs all seem to be on the increase lately. In addition, our once chirpy pick-up/delivery drivers seem to be generally disgruntled of late, and they put it down to the “Amazon Effect”.
So, what exactly is the Amazon Effect?
Are you, or is anyone you know, a Temperature Control Freak? You know the type; constantly fiddling with air conditioning and refrigerator controls and reporting on them to anyone within earshot. Well, I have such a friend.
TCF, as we will call him, has a digital temperature controller/thermostat and tells me that 39.2°F is the perfect temperature for his fridge. How he comes to this conclusion is beyond me, and quite honestly I don’t want to ask. Suffice to say that he’s happy with that after several months of laborious experimentation. And then there is the freezer ...
Now a fridge can only be between a narrow band of temperatures; too cold and it’s a freezer, too warm and it’s not a fridge. But a freezer can be kept at any temperature below freezing; from marginally frosty to cryogenic. It’s all down to how you intend to use it.
Foodstuffs will be preserved as long as they are frozen, but the appearance and edibility when thawed will differ with different temperatures and time. In Europe there is a star rating system for freezers as follows:
