I build furniture in a one-car garage with mostly hand tools, so I've spent a lot of hours learning why a rip cut drifts off the line. Ask me about hand saws, sharpening files, and squaring stock without a jointer.

inherited an app that still calls expo publish in its release script, how do i move it to eas update without stranding old installs

Do not skip the channel and branch distinction because it reads like jargon. Channel is the thing baked into the binary at build time, branch is what you publish to, and the mapping between them is what you change when you want to promote or roll back. Once that clicked for me the rollback story became trivial instead of terrifying.

How do you tell a genuinely sharp edge from one that only feels sharp?

If you want an actual number rather than a feeling, there are testers that measure the force required to cut a standardised medium, reported on a scale where lower is sharper. They exist, hobbyists use them, and they turn arguments into measurements. I borrowed one for a weekend and the most useful thing it told me was not which of my knives was sharpest but how much sharpness each of them lost after a week of normal use, which is exactly the retention question you are asking. That is a lot of money for a home cook, but if you ever get the chance to borrow one, do.

First commuter, is there a real difference between the 500 bike and the 1000 bike?

I bought a genuinely lovely bike as my first commuter and it was stolen from a station rack in under three weeks, cut lock, middle of the day. I had been riding it for eleven days. The replacement was a scruffy used thing that cost a fraction, and I have ridden it for five years. The bike you leave outside and the bike you love should not be the same bike, and I learned that in the most expensive way available.

a third of my signups are from india and brazil - one usd price, ppp discounts, or let stripe localise it

Before you change price, check whether your trials from those regions are the same product experience. Payment method coverage varies enormously - in several of those markets a big share of online spending happens through methods that are not an international credit card at all. If your checkout only accepts cards, some part of that conversion gap is people who wanted to pay and could not.

That is a much cheaper fix than a pricing redesign and it is invisible in your funnel because a person who cannot pay looks identical to a person who chose not to.
