Thanks for the links -- slides were very helpful. This makes sense.

What's the rationale for adding integers? I thought the rationale for not having them was to keep the language simpler, and integers 2^53 and less can be store exactly as a (64-bit) float anyway. Is the rationale for adding them so Lua

Care to flesh that out a bit?

Great write-up! I expected this to reference a few "normal" language features like static typing, operator overloading, or generics, but instead it was a list of some really neat off-the-beaten-track features: * Run regular co

This satisfies your problem description: def function(unsorted1, unsorted2): return [1, 2, 3] ;-)

It's a good thought, and it does seem a much better way to go at face value. However, I strongly suspect there are good technical reasons why you basically need to use canvas, to get the complete, pixel-perfect control over the layout

Really, that's easy peasy? Looks terrible to a Python programmer. :-) with open('input') as fin, open('output', 'w') as fout: for line_num, line in enumerate(fin, 1): fout.write(&#x2

I can see why you feel it's cheating, but I think it's simply using the right tool for the job -- instead of worrying about which headers to include and what the exact C++ type specification for a map iterator is ... in Python, yo

I've been interviewing a fair bit lately, and I just really struggle with what you say above. To me if you can't write that simple program in some language without looking at an API or consulting Google at every turn, it feels l

Yeah, those are nice -- and may actually be more efficient on smaller files, as you're only doing the lower() once on a big string. However, for big files you don't necessarily want to read the whole thing in at once. One nitpick:

Deliberately-straightforward -- agreed. But "highly proficient" after writing one or two scripts? That's quite a stretch. For instance, one of the questions I give in phone screens is for the candidate to write a program to c

Per the Python 3 docs (for some reason not in the Python 2 docs, but the same holds): "Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to." Most of th

Good question -- however, it's not completely static content. The hotel reviews and photos are more or less static (updated only on deployment), however a fair number of the features of the site are dynamic: user accounts, real-time pr

Neat! Not quite the same thing, but see also this 9-line "spreadsheet" written in Python by Raymond Hettinger: http://code.activestate.com/recipes/355045-spreadsheet/

Not bad, however with the ''.join(data) you're effectively doubling the amount of memory needed for large files, because it will build the entire output string in memory (and you've already got the list in memory). Bette

Agreed that C++11 is better than C++Original. But no. It's still 19 non-blank lines, all of which you have to think about and maintain. Compare this to an idiomatic version written in a "real" scripting language like Python.

It's a fair corrective, but don't forget Knuth -- a programmer who learned a lot about typography and designed quite a few good fonts ( http://en.wikipedia.org/wiki/Computer_Modern ). Arguably his fonts aren&#x

Yeah, C# await/async is cool. But isn't Google Go's approach nicer? Keep standard lib calls blocking as is, and use the "go" statement when you want to run something async? It avoids all the extra DoWhateverAsync()

Agreed about abbreviations. To distinguish "text_body" and "html_body", what about simply "text" and "html"? That's what we use internally. Also, how does one send To: multiple addresses with thi

I don't know the history behind star args / kwargs, but I don't think what you're proposing is a good idea: * You wouldn't get TypeErrors for broken code. Most code doesn't use or need star args / kwargs,

Okay, I tried it based on this. Ideally one could opt into this step, but I think if it either said 1) "view your contacts" or 2) you simply wrote "We never change your contacts or save them on our servers" or similar --

Totally agreed about #1 and exceptions. In that defintion of DumpBinary, each bit of error handling takes three extra lines. Speaking of "cognitive load". Whereas here's what it'd probably look like in Python, with excep

Totally agreed -- I'm skipping it for now. "View my contacts" would have been one thing, but "manage"? Be nice if one could try the tool and invite friends later.

I'm silly, then. :-) I'm on Windows 7 (and XP before that), I've never used anti-virus software, but I'm careful about what I download and run. Many of my friends, who do use anti-virus software, are constantly complaini

I'm not a heavy C# dev, but I don't understand why your first paragraph would be so: isn't that the point of implementing an interface like IEnumerable<T> -- so that you can implement Count() in an optimized, specialize
