I have a Bluetooth keyboard to connect to my phone, sounds like that.
I don't like typing on flat keyboards, part of the laptop form factor that does not appeal to me.
For me phone+keyboard is a laptop substitute rather than laptop+better keyboard

In my experience cashiers always finish the customers already in line before going on break or whatever

Reminded of container deposit machines that often aren't ready to take the next one as fast as I can get it out.
The stores where they're counted by hand are so much quicker

In general, a downside of mass production is that making new items is more efficient per unit than specialized repair jobs even though the wasted material seems sad.

As a currency nerd, I'm reminded of some things about US paper money.

Replacements for damaged bills are 'star notes', a separate serial number range ending in a star - since 1910 it's been easier to make those ahead of time rather than print new ones with the same serial numbers. Not replacing with something would make the print run a nonstandard size or serial number increment.

If an error on one bill has been discovered after the bills have been cut and wrapped into packs of 100, it's quicker to destroy and replace the whole pack than to find and replace the damaged bill(s) or save the undamaged bills for later use. With the latest $100 bill redesign, there were so many errors (with paper creasing) that it was worthwhile, but it was still a very involved process. The initial printings through much of 2010 and 2011 couldn't be released until 2016 as they were sorted. A new printing was ready for release by late 2013. The first wave was 6% star notes, an abnormally high error rate. The second wave was about 1%, still slightly high. The current wave is about two thirds of a percent, closer to normal.

*except for a few very small runs of high denomination bills decades ago

Russian election interference aimed at leftists like Black Lives Matter activists could get them to not vote Hillary (maybe stay home or vote for left wing third parties - I wonder to what extent Jill Stein was involved or if she was just a useful idiot)

That's one of my big gripes with the political correctness crowd - using words like 'racism' differently. It's not that they never have a point, but that it's disingenuous to use the same word for a different analysis

TFA said that the algorithm suggested multiple solutions based on different parameters
optimizing cost (but that annoyed the most parents and gave fewer high school students late starts)
pleasing the most parents and giving all high school students late starts (but this cost way more)
balancing those factors

The compromise was chosen and apparently pleased nobody. I'm reminded of the engineering slogan "fast, cheap, good - pick 2". It doesn't sound like a problem with the algorithm technology, rather how it was used

Early start times are a problem for highschoolers. This plan started high school later - but started elementary school earlier. That's a better fit to young kids' sleep schedules but would've wreaked havoc on their parents' schedules.

Start time changed from 9:30 to 7:15 rather than an overnight work shift. If changed had been used instead of shifted, it would've been clearer.

When those security holes are exploited to create botnets that then attack a 3rd party it's not a personal freedom to be stupid issue. Antivaxxers threatening herd immunity is a rather direct analogy.

Yeah, British teeth get a bad rap because you aren't into cosmetic whitening and straightening like Yankees, but you don't have more cavities. Maybe it's too hard to keep them white with all the tea. :)

I also wouldn't be surprised if tulips are treated like other agricultural commodities. Yet that seems to be missing the point, a joke about cryptocurrency being an investment bubble, since tulip mania is one of the most famous investment bubbles

We choose to go to college not because we are rich but because it is hahd.

Yeah, people making high six low seven figures for successfully managing a large operation don't bother me, gotta keep that talent away from regular businesses. The CEOs who get 8 digits for failing is the sort of thing that ticks me off

Yep. My college's fundraising appeals get thrown right out. If they can't get by on what they're already charging it's not my problem
