This is great information -- thank you. Do you have any general advice for switching over from one domain & TLD to another -- i.e., setting up redirects, etc... for those that have linked to the previous domain, as well as for Google in

On the monetary side, that is fixed in part by social security here in the US. It pays out monthly as long as you are old enough and alive. A kind of "old age" insurance.

Careful -- this is only locally optimal! You can do better :). [1] is the proven globally optimal solution of a very similar problem from one of the foremost experts in the TSP, Bill Cook at U of Waterloo. It is solvable in less than a seco

There have been some really really awful Lenovo Thinkpad trackpads in the last 2-3 years -- one specific one that I have used that you see a TON of complaints about was the X230 trackpad (google it, it's a mess). One of the worst I hav

Wow, the article didn't even mention the "original" solve of the 48 US city problem (one in each state) in 1954 (they included Washington D.C., so 49 to be precise)! For those interested, Dantzig (creator of the simplex metho

Piggybacking this, Coca Cola is the king of marketing prowess, in part because the product stays the exact same (or 99.8% the same). It's part of their "moat." Tech can't do that, in my opinion almost by definition due t

Can't edit now, but you're 100% correct, my typo was overlooked by me... three (or more) times!

>The problem with getting specific is that it ties you in to a specific solution. Agreed -- would Google have the same incentive to roll out Google Fiber if they could just use (slower) existing coax/cable lines as a middleman? It c

Coal is being switched out for natural gas here in the US... as a specific example, in 2012, see Plant McDonough right next to Atlanta, GA [1]. As I stated before, the reason is in part due to the effects on air quality (an externality), no

Carbon capture and sequestration (CCS) of CO2 is still in very early development and pilot testing, so costs are quite uncertain, and it is not in use in any reasonably sized coal plant in the US. For all plants >60MW planned to have CCS

My guess is that the "harbingers of failure" are just anti-popular-item folk. They like an item because other people (read: the huge market a company actually wants) don't like it, or because it's "different."

IP geolocation on my phone says that I am in Kansas (as a Sprint user), but I am definitely in Atlanta. Not that I think fine location data is necessary (I don't, and would like clear permissions options), but not sure IP geolocation i

Certainly this article was a bit heavy handed in its recommendations -- in my experience, there is a spectrum of people, with a spectrum of feelings about random interactions (some of which can even change from day to day, depending on mood

I would guess that this was an easier-to-market way to sell the user on an unfortunate price increase. I would imagine no one would disagree that they want a safe ride, and for Uber I am sure that indeed it will support newly discovered cos

Ah, this was a surprise since OR doesn't appear all that often on HN -- and I haven't sub'd to quite a few of these. Thank you!

No lawyer? Any reason why none was mentioned? Extortion is serious federal crime (across state lines, multiple companies, even clear admission of guilt). At the least it would get GoDaddy's attention vs. just asking nicely.

Interesting... although his explanation of TSP complexity is unfortunately incorrect (or misstated). The complexity he is describing is specifically for the naive brute force search [1] algorithm for finding the shortest path for TSP. And a

It certainly can't hurt to not be distracted -- Erdos was famously asexual, and it seemed to have turned out well for him! [1][2] [1] http://www.jrhenry.net/johnrhenry/erdos.htm [2] http://www.nndb.com&

It looks like indeed it's the latter -- the .gdoc files are just pointers, and moving them out of the google drive is akin to copying the pointer/shortcut... But, more than that, moving the .gdoc file pointer out of Google drive m

We have English classes since we need to read and write on a daily basis. We have math classes since we need to add/subtract/multiply on a daily basis. But why don't we have a technology literacy course where kids can learn a
