Re:Tire Pressure Sensor IDs: Why, Where and When (2015) on Wednesday October 08, 2025 @04:13PM (#45520095)
A couple years ago I picked up some Autel MX Sensors which support "cloning" through their diagnostic tool. Then I cloned my summer tire TPMS IDs to be the same TPMS IDs as my winter tires, and now I can swap them seasonally in only a few minutes with no need to make the car relearn them.

Re:Ask HN: Why does news.Y Combinator.com use a DNS TTL of 1s? on Saturday November 09, 2024 @07:58PM (#42097873)
NextDNS has a "Cache Boost" option that, when enabled, clamps answers to a minimum TTL to mitigate things like this. I've noticed that some Samsung IoT domains also have aggressively low TTL.

Re:Experian is a pile of dark pattern garbage on Monday March 13, 2023 @05:59PM (#35143558)
A few months ago I was able to bypass creating an account (and sidestepping all the dark patterns) by just calling their automated phone number and unfreezing with my PIN. Was pretty painless.
Phil's Lab is a really detailed channel covering multilayer PCB design skills. He shares a lot of nuance that would be gained only through years of trial/error or an apprenticeship.

Instead of paying for a separate SIM, I've been piggybacking on the "data only" SIMs that Google Fi let's you add to a normal subscription. No extra per-SIM fees, and you just pay for whatever data it uses at $10/gb.
