In my case it's because it's difficult to find one that isn't a shitty Chinese low ball version. They have TERRIBLE supply chain and cloning issues and half the official resellers are shipping junk ones out. The fake ones used to fail cal but they now load in firmware which ignores that cal step :palm: :palm: :palm:.

Argh, one of my pet hates there, computer nerdlings with a poor grasp of English expropriating an inappropriate word as a label for something and thereby forcing everybody else to mangle the language to use it.
Because some semi-literate nerk has misused "affinity" (which properly express the idea of "penchant for", "liking for", "preference for" or "predilection towards") you're forced to abuse English and create a clumsy neologism "anti-affinity" when there are perfectly good antonyms for "affinity" in existence - "aversion", "antipathy" "dislike" - but using them immediately exposes the weakness of using "affinity" to mean "required to associate itself with instances using a particular computer resource" or in the anti- case "required to disassociate itself from instances using a particular computer resource".
And then the bastards go and add injury to insults to the language by not even making it work properly.

It just doesn’t do anything and 1/3 of your capacity goes offline. And thus we learn the failure modes of a cluster platform written by amateurs on crack backed with marketoids.

Moral of the story, never trust people who treat language in an ugly way to be elegant or correct in implementing anything. The more buzzwords and neologisms, the less likely it is to work.

Everything but vegetable fat. Makes them taste as if they had been cooked in dishwater.
Real Belgian frites are cooked in beef fat.

My grandmother cooked her chips in beef fat.
She died of heart failure at 72. I think her blood was probably lumpy :-DD

My father occasionally gave me something he had as a kid. A slice of bread with beef dripping.
Back then farmers won prizes for animals with the most fat.
--- End quote ---
When I were a lad we used to have two brown pots in the fridge. One contained beef dripping (complete with a layer of jelly and some crispy bits) collected from Sunday roasts, the other contained fat poured out of the bacon pan (with a few crisp bits for good measure). I hardly ever roast a joint of beef so I only have one little brown pot in the fridge.

Even for straightforward topics where you don't have to generate the source material (such as front-line war reports), John Simpson reckoned an hour post-processing the material gave you a minute of content.

Back in my Journo days we used to reckon that for long form written articles (3k words and up) it took about a day to research and write a thousand words, with a rough logarithmic relationship for shorter pieces. So, a good 200 word piece was half a day's work, 500 words a whole day, 1k words 2 days, until you got to 3k words where it settled down to a flat output of 1k words/day. Unfortunately rates for freelancers were set at a fixed £/1k words rate, so the feature writers used to do much better than the people who contributed short pieces.
For context: newsreaders tend to speak at around 160 words per minute, the average reader will read at 200 words per minute.
