How do you measure a great car? There are three factors I've observed: great cars can accelerate, great cars are fun to drive, and great cars have steering wheels.

Sorry, but leadership cannot be reduced to these three factors. There are many excellent leadership frameworks out there which provide great insight into how different leaders operate, and what the great ones have in common. Look up topics like Spiral Dynamics, the Action Logic leadership framework, Kegan & Lahey, and the Integral framework, and you'll have some good starting points on models of adult development that correlate to effective leadership.

I wrote a blog post focusing on the #2 problem mentioned: multiple testing. I simulated the typical mitigating approaches, and comparing them against Thompson sampling (code in GitHub). https://www.lucidchart.com/blog/2016/10/20/the-fatal-flaw-of...

I'm not a Bayesian fanatic, but given how perfectly A/B test optimization fits in the Bayesian approach, it's a shame it's not yet the de facto standard.

I think the primary reasons are (1) it's not as intuitive (especially for the uninitiated), (2) it's harder to implement an automated feedback mechanism, (3) FUD. E.g. https://www.chrisstucchio.com/blog/2015/dont_use_bandits.htm... lists devastating complications with correct multi-armed bandit tests, and then in fine print admits that traditional tests have all the same complications.

In the case of Fandango showing an interstitial ad when attempting to check out, I can't imagine that wouldn't hurt conversion, and I can't imagine that conversion wouldn't be one the key metrics they would test with. I would guess it's more just a lack of care. Someone said "we need our website to make more money" and someone else said "okay, I hear that ads are for making more money."

The point is, you don't know what that number is unless you do the math. It's not a matter of "judging it". It is a matter of calculating it.

If you "peek and halt" without doing the math. You might as well have a random good result in the first 10 and say "look! Positive results!". You recognize that is ridiculous. So when is peeking and stopping not ridiculous?

A: when the statistical power is sufficient for the observed effect. In the examples -- 1600 or 6000 for a 10% or 5% effect, respectively. And much less for a 20% or 40% effect! -- but you don't know the number required unless you do the math.
Right. In California trucks have a lower speed limit than cars, which results in what feel like pretty dangerous situations.

The right lane is pretty much for trucks going 55.

The left lane is a combination of:
* Trucks going 60-65 to pass a truck in the right lane
* 'Typical' cars who are going 75ish
* Fast cars who are going 80-90

So there is a huge disparity of speed in that lane -- and that disparity seems like it must be a huge factor in many highway accidents.

It always feels really dangerous. I wonder if it is safer than just having the trucks have the same speed limit as the cars.
You and I think that the cube root function is the simplest approach. The student doesn't necessarily agree. And I disagree with you that the most general approach is necessarily the simplest.

> i'll ignore rest and focus on 2x the body weight via deadlifts. for me this would mean doing 180kg (400 pound) deadlifts which most people simply never ever achieve with 2-3x/week routine (I am lean 188cm tall sporty guy).

Most people follow the wrong routine. I went from no prior weight lifting experience to a 180kg deadlift at 75kg body weight at 180cm height in just over six months training three times a week. No one considered this unusual. The difference is that I was training together with experienced powerlifters.

I stopped competing in powerlifting nine years ago and now lift casually to keep in shape and as physical therapy for injuries sustained from other activities. There is no way I could get from the 100kg I lift now back up to 200+ using this approach, and most people I see in the gym don't even try as hard as that. 180kg is definitely possible training twice a week if you train right.

What makes you say this? Anecdotally I have known a few 60- and 70- year old powerlifters who still put up 140kg+ deadlifts and they seemed fine. The older retired Olympic weightlifters I have met seemed fine as well.
I too worked on a Messenger-based text game, and found that when you're sending sequential messages, the trick (though unnatural) is to add delays not based on the current message being "typed" by the code, but based on the previous message.

For example, if your previous message contains 100 words, and the current message to be sent contains only 10 words, you still want a long delay -- you're catering it to the user reading the long message. Similarly, if your previous message was short and the next one is long, the delay doesn't have to be long because otherwise you're just making the user wait for no reason.

Love Discord. Most of my friends and I have switched over from using Mumble and it's been great.

I run a small Mumble host [1] and I've always thought of the idea of wrapping the Mumble client and server APIs to function like Discord/Slack as an open source alternative. Mumble is great and all, but the UI/UX appeal of Discord is so much better.

Keep up the great work!

If you were teaching a more formal method, I can see marking it wrong. But you're mistaken to think the student can't find the answer that way. If I had to solve x^3 = 7 in my head, I know that 2^3 = 8, and my next guess would be 1.9

1.9^3 = 6.859 (ok, I'd need a pencil for this)

Now I know the answer to two digits, "x is just a bit more than 1.9", and one can keep going if more precision is needed.

The technical issue was the result of a top down demand on engineers who weren't given enough time to deliver/test a safe design. I'm not sure how this can be directly attributed to the chaebol structure although the Lee heir in question was also pushing the Note 7 redesign effort.
I guess you could say this is a form of technical debt, or technical stubbornness.

I used to work for a company that specialized in Solar Panel data. I was hired to help the company catch up on their client queue (those waiting for the product to be set up).. and when I first started they were behind by about 140 clients and I had gotten the client queue down to about 30 clients remaining.

So our company would sell solar panels to corporations, and then they would put kiosks in the lobbys of their buildings so their clients could come take a look at the energy savings and other information about the building. It was a very popular way of doing things, especially in cities like New York, Chicago, and Los Angeles. Well, my job was actually designing the graphics for what was displayed on those kiosks and then syncing the data with the graphics.

There was a platform that did the work, but I still had to design the graphics and type in all the serial and model numbers and all that to sync everything together and make it show it in chart form in a gorgeous view. Anyways, for years, it was being done in Flash. Unfortunately, as progressive and dominant as our company was -- at one time, their technology was the best, even having received several awards. Over the years, HTML5, JSON, and other technologies were better and faster -- and could read data from a database just like as our system could, but turnaround time for production was faster for others. It took about 1 week for us to develop, set up, and sync everything from system to database. Now these other companies were able to get everything done in days, rather than a week or more. I think a huge part of the problem was my company had these corporations interested but forgot to hire enough people to actually do the work.

We did have an in-house software developer working on improving this technology, upgrading the software, but they seemed very reluctant to adapt the new software quickly. I had worked in the new software for a few days, and then all of a sudden, they called me into an office, and laid me off. A few months later, everyone else followed, and today, I think the company only holds on to about 2 or 3 employees who just maintain all the kiosks and software because of the existing contracts. Or maybe they went under... their website doesn't even work anymore.

Why did they go under? We were warned that technology was changing fast and that we needed to do something about it... and it was just the reluctance of the CEO to adapt the technology and push it out faster. Our competition slaughtered us. Luckily, it was my second job, so I worked out a great deal with them on letting me go.. I got about a month of vacation time on the condition that I wouldn't go file for unemployment. Obviously, already having another job, it worked out in my favor.

The 1541 had one at 1MHz.

The really fun thing about these was that you could actually download code to them and run it, so if you did have code that was small enough and CPU intensive enough and required little enough IO, you could in fact use them as an accelerator of sorts (but limited by a slow serial port and 2KB(?) I think of RAM on the drive)

I know of various code that downloaded code to it, but usually loaders or just to do things like blink the leds - I've never seen code that actually used the extra CPU for anything serious. I'm really curious if any exists.

The student demonstrated that they can do such problems with positive integer solutions. Possibly even negative integer solutions. But certainly they did not show any sort of reasoning along the lines you wrote.

But let's take your method. Your method is wrong because you aren't finding the solution. You are finding a sequence of numbers that converges to the solution. But this isn't the solution to the equation. The solution to the equation in question is a number and not a sequence.

The answer, over the reals, is 7^(1/3).

That is possibly the most condescending thing I've ever read. Whatever the author tried to make themselves less abrasive, it didn't work very well.
Let's take a calc 2 example. I ask students to integrate ln(x). I want to know if they can do integration by parts when one function is 1. Some of them can memorize the answer and just write it down. I don't give them credit for this. I'm giving an easy problem because I just want to know if they know how to do parts with 1 as one of the functions. I don't want to load the test with hard problems so that I can eliminate any possibility of memorization at play.

It's interesting reading all the replies I've gotten. It's nice to see other peoples' perspectives. Including yours.

I agree, but testing for understanding (as opposed to Socratically probing for it) is more time consuming, complex, and difficult than just testing for correct answers.
