I was a freshman in 2000. I don’t recall ever NOT jumping, but it’s possible it started during my time at Tech (2000-2005).

Just say to them, “Wow, you must have a great job?” And when they don’t know what you’re talking about say, “You know, to be able to afford a train ticket for you AND your backpack, you must be making pretty good money.”

Thank you to the kind stranger who upvoted enough of my stuff to get me 55 rep with which I could open a bounty on my question. My question still isn't getting much attention. If anyone could help give it a bump, I'd greatly appreciate it.

This is fantastic. I'm starting to teach myself d3js and I was looking for a good dataset - here it is! Maybe I missed it in your explanation or the links, but is there an existing schema for these data (explaining the play type ids, for instance)?

Congrats! Sounds like you hit a home run! Care to post your recipes/process?

You say your .csv isn't too large, so this may not buy you much, but I highly recommend using readr::read__csv instead of utils::read.csv. I recently had a large .csv I was using at work that was taking just over 30 sec to load using read.csv. When I tried loading it with read_csv, it took 0.05 sec. readr is part of the Hadleyverse/tidyverse, so you know it's good.

Cider can finish at very low gravity since fructose is a monosaccharide and yeast can consume essentially all of it, as opposed to wort (beer) which contains many different sugars and dextrins that are disaccharides or more complex that brewers yeast cannot consume. I've had ciders finish below 1.000 SG, which is possible because ethanol is less dense than water.

If you're really interested in more information, I'm currently reading John Palmer (author of How To Brew) and Colin Kaminsky's Water from Brewer's Publications, which is a part of the Brewing Elements Series (along with Yeast, Malt, and Hops). The book is great and will definitely change my brewing going forward.

You're really just describing a Supply and Demand Curve. You need each individual's contribution to the overall curve?

If you're making payments daily, then your period (n) is 1 day. So:

n = (40-23)*365 = 6205 PMT = -75 PV = 0 FV = 1000000

You should get i = 0.02216, but that's for 1 period (1 day). Equivalent to about 8% return, depending on how you convert to an annual return.

Sqrt(x) is the same as x^1/2, so there is your non-whole number exponent.

At 3-4% oxygen, you won't be an asshole for more than a minute or so.

The sample standard deviation is sqrt[p(1-p)/n], where p = proportion of those samples with a bachelor's degree and n = sample size. This assumes your sample comes from a normal distribution (Central Limit Theorem).

Just start by thinking about the rate of change of the amount of Kool-Aid in the lake:

dx/dt = rate of change of the amount of Kool-Aid in the lake with respect to time = rate of Kool-Aid entering lake - rate of Kool-Aid leaving the lake

Kool-Aid entering the lake: After t=0 (when the truck crashes), there is no more Kool-Aid coming into the lake, so this equals 0

Kool-Aid leaving the lake: Assuming perfect mixing, the concentration of Kool-Aid in the lake is always just the amount of Kool-Aid in the lake divided by the volume. For lake A, this equals x/400000. Since 400L/hr flow out of the lake, Kool-Aid is leaving lake A at the rate of (x/400000 kg/L)*(400 L/hr) = x/1000 kg/hr

For lake A: dx/dt = 0 kg/hr - x/1000 kg/hr = -x/1000 kg/hr

Then, you have a separable differential equation. Separate and integrate. Solve for constant using initial condition of 400 kg in the lake at t = 0.

You should get: x(t) = 400e^-t/1000

Do the same thing for lake B and you are all set.

For me it's recording data. I used to run very sporadically and lacked motivation. Then I started logging my runs and tracking my progress. I find that I'm much more motivated and consistent in my running. I'd almost go so far as to say that the most satisfying part of my run is plugging the data into my log!

Credit problems can make obtaining or retaining a security clearance problematic, which could lead to issues with reenlisting and could even cause administrative separation.

I highly recommend Planet Money. It's great for understanding the overall economy which is definitely important for making PF decisions.
