  • Is there anything you have done for which, if I had done the same actions, I would be irredeemable?

    Is there anything that you have done, for which if I had done, you would expect me to jump into the volcano?

    Feel free to judge yourself just a tiny bit more harshly than you would judge others. But only slightly. Give yourself as much of a break as you would give me after expressing remorse for my actions.


  • I think that to be eligible to be president, your age as of the last day of your next term should be less than the life expectancy of your constituents. You want to serve longer, you better make sure your constituents live longer.

    As far as Biden stepping aside, I don’t think it’s a bad idea at all. Find a 40- to 50-year-old combat veteran who grew up with wind turbines and solar panels on her family farm, and has been living and working in a blue state for the past 5+ years. Have her run on a platform of “Ok, Boomer”.

    Juxtapose a picture of her running with a pack and rifle against a doctor looking at X-rays of a foot with a magnifying glass. Photos of her family’s wind farm against headlines of Trump denouncing wind turbines. Her smiling at an award or promotion ceremony against Trump’s scowling mugshot.





  • The hotter it gets, the thicker the oxide layer form

    This is accurate enough for tempering of most cutting tools, but technically, the oxide layer will continue to grow if you hold a lower temperature for a longer than normal time, and might not fully develop if you reach a higher temperature for a shorter than normal period of time.

    This property useful if you are trying to develop a specific color rather than achieve a specific metallurgy. You can heat to a lower temperature for a longer time to develop a deeper, more consistent color.

    In my experience, it’s easier to develop colors with an oven or propane torch rather than a forge or acetylene.


  • I won’t say that this blade is properly heat treated; it probably isn’t. In welding, the problem is the wide variation of heat affects in a very small zone. You can have material that is very brittle just millimeters away from material that is very soft and ductile.

    You’re describing “normalization”, which is a process that makes steel uniformly tough, but “plastic”. When you flex it, it bends, and stays bent. “Annealing” is a similar process, where the temperature is raised a bit higher, and the cooling slowed even more. “Annealing” leaves the steel very soft.

    In tool making, you’re first looking for high hardness (acquired with a “quenching” process). This makes it very brittle; it has no elasticity.

    Next, you’re dialing back that hardness with a “tempering” process, which is done at a lower temperature than the normalization process, and the cooling can be much faster. When tempered, it’s still very hard, (significantly harder than “normalized”) but now it is slightly elastic. It will flex, but beyond a critical point, it just snaps; it probably won’t take on a permanent bend.

    These colors are oxide layers that form at temperatures in the “tempering” range.





  • The 15% or 20% guidelines are based on the amount of work performed by the tipped employees (who earn less than minimum wage before tips.) the amount of the check correaponds pretty closely to how much time a waiter has to spend serving a table.

    Drivers are not usually employees; they usually have $0/hr in wages, and pay their own fuel and vehicle expenses. Delivery services typically pay $2 per trip, and a trip will involve 2-4 stops. The base pay from the delivery service does not even cover fuel costs, let alone the driver’s time.

    The amount of work a delivery driver performs is not at all related to the amount of the check. The 15%/20% rules are not remotely close to the amount of work the driver performs. $8 on a $20 order is a garbage tip if it’s a 10-mile delivery to a fourth-floor walkup. $4 on a $70 order might be a decent tip if it’s a 1-mile delivery to a front porch.

    The appropriate tip for delivery is based on mileage, not food price. $1 for pickup, $1 for dropoff, and $1 per mile is a pretty basic tip. A driver can complete about 3, $2 runs per hour. $3 tips gives him a gross income of about $15/hr, and he can net about $10-12 of that after expenses.
