<p>Depends a lot on humidity. Condensing a fridge full of humid air releases a fair bit of heat.<p>Also a fuller fridge will have much more thermal mass and care less.<p>But yes, exchanging the entire air volume of a fridge every time you open it is very energy-wasteful.</p>

<p>Some more things to consider: Sugary things like marinades and rubs will stick more as they caramelize compared to just salt & spices. This is great if you're making a pan sauce, as there's more to deglaze. But I've had my pan act so non-stick in some cases that I couldn't build a fond.<p>Also if the surface of the food is wet, it can cool the pan a LOT on contact, as well as cause other reactions that promote sticking. This is especially true with too little oil.</p>

<p>Considering the list was generated from data, not just the author's opinion, I wonder what criteria you're using for "should".<p>My guess is a lot more of the general population feels the same (negative) way about it, but your sample of people you've seen reacting to it is giving you selection bias, thinking more people enjoy it</p>

<p>Have an annual salary in mind for a similar role, chop off the last three zeros, and that's my hourly rate.<p>It works out to approximately double which is just enough to account for things you would normally get from an employer:<p>- payroll taxes (SS/Medicare)
- PTO/sick days
- equipment & supplies
- training/conferences
- health insurance
- retirement savings<p>Etc</p>

<p>Thanks :) I love that I'm not the first/only one to do one of these in Brainfuck (especially in direct response to Ben's series).<p>I have a feeling the approach I take will follow from whatever I decide for RAM zeroing. The purist in me is still a bit put off by the idea of preprocessing. It feels more like a compiler+CPU rather than just a CPU. If I go the "highest address counter" approach where I synthesize zeros the first time a RAM location is passed, I probably won't do the loop pre-processing.<p>I could do a hybrid approach where both jump points are indexed the first time the loop is scanned. This would achieve amortized constant time. I think I could live with that...</p>
