A commonly requested feature in .NET is the ability to use covariant return types. "When you want to go to it"

It's like multiple inheritance -- there are times when it is really useful. Covariant return types has been on my wish list for a long time!

Quote: It should be noted that most of the discussions about this feature happened in early 2015, over two years ago. And nothing has been done with it, at least publicly, since the proposal was formally written up back in February.

The ELO system, which most chess federations use today, ranks players by the results of their games. Although simple and efficient, it overlooks relevant criteria such as the quality of the moves players actually make. To overcome these limitations, Reseachers have now developed a new system. Oh great. Now the AIs have started trash-talking.

Is this approach any more valid than the numerous existing comparison systems?
I don't see how you can really factor in advances in chess theory let alone the advantages that modern players have from working with AIs and databases.
Is there any point doing so anyway? Depending on your age, you'll have your hero, whether it be Carlsen, Kasparov, Fischer or whoever. Trying to compare chess players across eras makes no more sense than arguing over whether Stanley Matthews was a better footballer than Lionel Messi when in many ways, they were competing in an entirely different sport.
Slogans aren't solutions.

So, a player who makes awesome moves, but always loses, could be ranked higher than a player who appears clueless, but wins?

I wasn't aware that there is any other options. After all it is a game and it is all about winning...

Not a problem.
The world will just end up with an "american internet" and an "everyone else internet".
We've been living with that with the English language for so long that we'll just ignore the "american internet" like we do "american English".
Not a biggie, at all.

Errr... the rules they look to change only began in 2015.
Can you remind me of the horrible mess that was the internet before 2015? I don't recall.

Sure, because, before then, politicians hadn't got* involved in the "who owns the interwebs?" question.
It was ours, as in "the people's". They added rules so that they could later change them to "own" it.
* Aktcherley, this should be "gotten", because it's only american politicians who say they own the interwebs.

Actually its the big corporate telecoms who "own" the "interwebs" since they're the ones who built, continue to build, and maintain them.

Fair enough, but they're rightly content to own (and rightly make a fortune from) the infrastructure.
I'm talking of the more ephemeral concept, not the wires and servers.

Isn't the basis of net neutrality that ISP's and telecom giants can't provide faster service to those willing to pay (ie. Netflix, Amazon, Alibaba, etc...)? That all data needs to be treated equally?
That seems more infrastructure and less ephemeral to me.
While I can see both sides of the issue I wonder if our ever increasing nanny states won't take it to the next level where they make the same rules for individuals. Every home can and must get the same connection speed regardless of the occupants willingness / ability to pay. Every company can and must get the same connection speed...

What was happening before was that when Netflix came out, some providers were slowing down Netflix traffic, so even if you were paying for a certain connection speed, your Netflix connections were being slowed down.

I still prefer a consumer based solution (protests, boycotts, etc...) rather than a government regulation solution.

Unfortunately, this strategy reminds me of Allan Sherman - The Let's All Call Up A.T. & T And Protest To The President March - YouTube[^]
Just as, back then, threatening to change phone companies was empty (What other phone company?!); now, with most people contractually bound to their ISP, and having few options, there's little leverage to bear on the providers.

The power of modern programming languages is that they are expressive, readable, concise, precise, and executable. Cogito ergo code
Or rather, whatever is the present-tense, first-person indicative version of to code. (I miss Grade 8)

Sadly, there isn't a definitive English word for this, so we just use the Latin: elephantare.

IMO, not really.
The BFS example that the author cited is no more or less than the Python code -- if you know the meaning of the symbols, it's easy to understand. Just because those symbols are mostly expressed in English words doesn't make it more readable. queue.popleft is still meaningless to someone that doesn't know what a queue is, and frankly, I have to guess at what "popleft" means with regards to a queue, and I've been using Python for a while now (but am no expert at it.) As it is, I would expect a popright() as well for symmetry, but I much more prefer the word "dequeue," which is more obvious to me given my background with programming languages (and would be the term I would use if I was implementing a queue.) But that's me.

Why should a queue (deque) be conceptualized as right-to-left or left-to-right?
Why not top-to-bottom (like a disposable cup dispenser on the side of the water cooler...)?
Defining it as "in left; out right" may require a mental translation from the problem space to the code space. The "impedance mismatch" between the spaces is larger than necessary, especially because the operations are not named symmetrically, as Marc noted.
Yes, the programmer could encapsulate it with naming that matches the problem space, but that adds complexity to the solution. Just naming the input and output as such ought to be sufficient (IMHO). If there are operations that bend those definitions, so be it.
(I don't see the reason for the deque class to exist. It appears to be a doubly-linked list with some LIFO queue concepts wrapped around it with the left-to-right convention.)
