el_devo··on OpenAI Five at Dota 2 – The International [video]
Here is a post from the Dota 2 subreddit discussing the timing with proof that OpenAI's reaction was over the 200ms minimum:

Yes, as the sibling poster said, there is a 200ms reaction speed restriction on OpenAI. Also note that OpenAI is using the Dota 2 bot API (its input is not pixels, and its outputs are not mouse actions and keystrokes), so it has more precise information than the human team on things like unit coordinates and can target its actions more exactly.
el_devo··on The Great Firewall of Yale
For what it's worth, at my university, UNC Chapel Hill, there are two networks, one of which requires you to install a custom root certificate, and is the network that the university prefers you connect to. For devices on which this is not possible, there is another network which only requires that you register your device's MAC address to your university id for access.

Regardless of which option you choose, you are required to install another program (unless the OUI of your MAC indicates that it is a device other than a computer) which scans your computer for malware and any software which the university does not allow you to have, such as torrenting applications, and will not allow you to connect to the network until after your machine is cleared. This program must be running the entire time you are connected to the network or you will be disconnected.

As a student who works as tech support in the dorms, it certainly is a nightmare!

There is also a link in the upper-right corner of the page that avoids this problem.
el_devo··on Writing A Lisp Interpreter In Haskell
I would say this tutorial is an excellent one to read through when you are first learning Haskell, and then return to it later when you have a better understanding of the language. Some important concepts are glazed over, and you will almost certainly not understand what is going on the first time you read the tutorial.

Once you are comfortable with Haskell the code makes much more sense and is a great starting point for writing an interpreter of your own.

You can also click the lower right corner, then click the windows flag on the menu that pops out.

This has exactly the same problem as the above method.

I went back and used the assist, and this time ended up with a 7.8. It was a much better experience!

As a person with red-green color deficiency, I got a 3.1. I'm proud of that!
el_devo··on Why Science Majors Change Their Minds (It’s Just So Darn Hard)
It isn't that the math is too hard, it's that the students want to run before they learn to walk.

I'm a 17 year old in high school right now and having taken Calculus AB and BC (I and II) the teacher was constantly skipping material that I think was very important to have a general understanding of Calculus. Needless to say, I read the book to learn everything she was skipping, and I was also the only one who got a 5 on the AP exam. My classmates weren't stupid, they had just learned to solve very specific problems rather than actually learning Calculus. The very specific testing curricula hurt actual learning.

Another issue lies in the fact that (at least at my school) calculus and other high maths are seen as only for the very smartest kids. We need to change that. If students are required to have been exposed to calculus they won't be in as much shock when they get to college.

The availability of higher classes is a big problem as well. I was super lucky to find a public school program that allowed me to take classes with a community college, because otherwise there would have been no classes for me to take past sophomore year and Calculus I. I'm taking Multivariate Calculus next semester, and I doubt many high school students have this opportunity at all.

I realize that I'm in the minority here. Not many high school students have the opportunity to take Calculus III their senior year, and that really needs to change.
