Comment Re:Sanity checks (Score 1) 213

Depends on the business case for one or the other. In this case, the bank may well have decided 'the less than, literally, 600-in-7.5-billion chance of having somebody exceed this age range is less important to us than stopping incorrect payments going out to people with ages that are far FAR beyond 'wildly improbable.''

In other cases, it would be far better to have multiple incorrect accounts than to miss one valid but wildly outlier account.

What if you think 'Out of 7.5 billion humans, there are, at most, 600 people over the age of 110. How many of the 0.00000799927238618 percent of humans who fit this category likely happen to live in our country? How much bigger is the number of incorrect or fraudulent records where the age is above, say, 110?'

Why would someone who is not a programmer set up such an arbitrary limit?

Probably because it's not arbitrary; most people don't live to be 110, and everybody knows you're supposed to perform sanity checking. According to a quick google search (the height of scholarly rigor,) there's maybe 300 people in the world who are older than 110 years. The most wild estimate is 600.

On the other hand, fraud is a real thing, not to mention straight up human error; somebody dies, they don't get taken out of the system, so the money keeps going out.

I doubt very highly it's a 'two digit year' storage issue.

More likely, it's perfectly correct and reasonable boundary checking; an age should never be less than 0, and never more than, what? How many people are actually older than 110? She is an extreme outlier, and proof positive that the boundary checking is working.

Performance predictions have an optimistic bias.
It's known as the planning fallacy
It amazes me how people who should really know better fall for this.
For example, if the last time you did it, it took 3 weeks, a good prediction is that this time it's going to take 3 weeks.
Yet most people will predict less than 3 weeks - even if you point out the planning fallacy to them before hand.
I can almost here the rationalizing; "It's not going to take 3 weeks again, because we aren't going to make the same mistakes again."

But it's far, far, worse than just an inability to predict accurately.
Frequently schedules are determined by need rather than reality. As in, we need this done by Tuesday - make the schedule accordingly.

Ok, so it's like the SCOTUS and pornography; you'll know it when you see it.

So, the followup question would be: you have teams of competitive StarCraft players who train in amounts and methods very similar to atheletes, and who play for cash prizes, sponsorship deals, and what not; what term would you say applies?

Comment Turing (Score 1) 630

My first 'formal' computer programming training was in High School, using a language developed at the University of Toronto called Turing.

It was a cute little language, and I remember doing some fun stuff in it, including some basic 3d wireframe engine work. Which was pretty exciting stuff in high school computer programming in the early 90s on a 386.

You know people might need to get more than two loads of laundry done in a day. While one might not need to supervise the washing machine, you do need to be around to move the laundry to the dryer, so that you know, it drys. Where with a normal washer I could have the wash done in thirty minutes, throw it in the dryer, start ANOTHER load in the washer and then run into town to get some errands done, when I get home an hour later, oh looks. I have a load of dry laundry., and another load of laundry to put in the dryer. Meanwhile you are still waiting for your first load of laundry to wash and I'm getting load number three in the washer.

You'd be amazed at how much laundry two kids and two adults can produce in a week.

Given that I had laundry duty for the wife and three daughters, I know exactly how much laundry can be produced in a week. I also know that it's not unusual for the laundry to sit in the washing machine for three hours after it's run before I get around to moving it to the dryer.
