Whatever you choose, run the export once a quarter and actually open the output. Half the people with an export button have never once pressed it. Mine was quietly producing an almost-empty archive for four months and I only found out because I got curious.

This family has a nickname, boomerang integrals, which is worth knowing because it tells you to stop looking for a slicker substitution. Same trick shows up on ∫ sec³(x) dx and on ∫ e^(ax) cos(bx) dx in general. Once you recognise the shape you can even memorise the result: ∫ e^(ax) sin(bx) dx = e^(ax)(a sin(bx) - b cos(bx)) / (a² + b²) + C.

The recognition quality also depends enormously on how tidy you are. My handwriting is bad and search finds maybe half of what I want, which is fine for browsing and useless as an index.

Worth auditing what you have allowed through, because almost everyone builds a leak into their own focus mode. People whitelist messages because of a family thing, or allow one work app because of an on call rotation, and then the mode is doing nothing except making them feel organised. On my phone the work focus allows exactly one contact and no apps, and my home screen in that mode is a single blank page with nothing on it, so unlocking the phone shows me nothing to tap. That last part cut my pickups more than the notification rules ever did, because the reward for reaching disappeared.

Rule that saves a lot of pain: pick await or .then per function and do not mix them. Mixed style is where the stray promises hide, because you stop being able to see at a glance which values are resolved.

This one bites people constantly. Same reason your first shot of the day behaves oddly on an espresso grinder.

Found space eleven days later on a partner, one day earlier than planned, for slightly fewer points. Not the outcome I feared.

I did not know holds were even a thing. Adding that to my checklist along with the transfer timings.

One percent refund rate on a digital product is at the low end of normal and you should be pleased with it rather than annoyed. Do the arithmetic on the alternative: if tightening the policy to a case-by-case review costs you even two percent of conversions on 190 sales, you have lost more than the $78, plus the hours you spend arbitrating refund requests, plus the occasional dispute from someone who felt stonewalled: and a dispute costs you a fee on top of the money.

Generous refund policies are usually cheaper than they look precisely because they prevent the expensive outcome.

Adverts, support forums, and the questions people ask in industry groups. All public, all specific, all better than a title filter.

The two-hour rule comes from the water-resistance and rub-off assumptions baked into the testing protocol, not from the filters expiring on your face. Sitting still indoors you are not removing much product. I reapply before going outside rather than on a timer, and that's the version almost everyone I know eventually settles into.

Whatever you do, do not run git push --force to make the message go away. That is the one command in this area that genuinely destroys someone's work, specifically your colleague's. If you ever truly need it, --force-with-lease at least refuses when the remote moved under you.

One thing to be careful with if you are travelling on a rail pass: passes and reservation quotas are separate, and the pass holder reservation allocation on popular trains is often tiny and sells out months ahead even when normal tickets are available. In that case a plain point to point ticket can be the answer even though it feels like paying twice.

Terse: second trainer. Race in your better trainer. Buy the plate for marathon two, once you know whether you even like the distance.
