A customer at the shop argued that a $20 chain checker is a waste of money

He said you can just measure chain stretch with a ruler and that the tool is just for upselling. I've seen guys get it wrong with a ruler and wear out a whole drivetrain, though. What's your shop's policy on checking for chain wear?

Got my first BCI headset to work by putting a wet paper towel on my forehead

My cheap EEG headband kept losing signal every 5 minutes during a coding session last Tuesday. I remembered reading about sweat improving conductivity, so I just folded a damp paper towel under the forehead sensor. The signal stabilized immediately and stayed locked for over an hour. Has anyone else tried a weird physical hack like this to get a better read?

Serious question, a client in Omaha told me his last barber always used a straight razor for the neckline.

He said it gave a cleaner finish than clippers with a guard. Has anyone else found that to be true, or is it just extra risk for the same result?

Update: tried the 'hold the comb vertical' vs 'horizontal' thing for blending

For the last month, I tried blending fades holding my comb flat against the head like I always have. Yesterday, I switched to holding it straight up and down, almost like a guard, and just flicking my wrist. The blend from a 2 to a 1 guard went from taking me like 4 passes to just 2, and the line disappeared way cleaner. It felt weird at first but the speed and finish are totally different. Anyone else have a small change in how you hold a tool that made a big difference in your fades?

Serious question, got a 30-day ban from a hiking forum for a trail condition photo

I posted a picture of a washed-out section on the Mist Falls trail in Kings Canyon last week, and the mods said it was 'unverified fear-mongering'. I just wanted people to know it was sketchy before they went. Has anyone else been banned for sharing what they thought was a simple safety heads-up?

My new burger recipe got 47 orders in one night at the food truck

I never expected that kind of volume for a lamb and feta special. Has anyone else had a simple menu item blow up like that?

Remember when training a basic image model felt like buying a new computer every month?

Back in 2020, I dropped about $800 on cloud credits to train a simple classifier for a hobby project. I had to babysit the thing, tweak settings constantly, and the whole process took over a week. The bill felt insane for what it did. Now, I see these new open-source models that can do the same thing in hours for maybe twenty bucks worth of compute, if that. It's wild how fast the cost of just trying something out has crashed. The barrier to entry is basically gone. Makes me wonder what we'll be able to build in a couple more years that seems impossible now. What's the biggest cost drop you've seen in your own projects lately?

Got told my field notes were 'unreadable' by a senior dig lead in Crete... started using a simple grid system the next day

PSA: I bought a $40 'universal' laptop charger that fried a client's motherboard in under a minute.

Some techs say cheap adapters are fine for quick fixes, but others argue you should only use OEM parts, so what's your rule for third party power supplies?

I used to think steamers were just for extractions until a client in Tampa said something

She told me 'my skin feels way more hydrated when you steam before the mask, not after' during a facial last month. I tried switching the order on my next 10 clients and the feedback on hydration was way better. Anyone else find a simple step change that made a big difference?
