In the examples, 0x3bffffffffffffffff decodes to -18446744073709551616, which doesn't fit into int64_t. Why didn't they switch to bignums after INT64_MIN (-9223372036854775808) instead? Seems a bit asymmetric.

The full text is a little less alarmist:

According to the original paper, 81% of SO users didn't provide their age, so to conclude that older programmers are more knowledgeable from this data seems unwarranted. The paper acknowledges however that SO population may not be a good proxy for the programming community in general:
Research into the nature of the SO population and its relation to the programmer population at large needs to be conducted, in order to support inferences to the programmer population. Further investigation is needed of how SO measures, such as user reputation and question scores translate in to programming knowledge and ability. Research on the relationship between age and knowledge on SO should be related to the existing literatures on aging and on the development of expertise.[1]

The programmer inadvertently used a vendor-specific feature. This is the key difference. Nobody writes perfect, standards-compliant code all the time, so the compiler needs to tell you when you are doing this.

A quote from Stroustrup:
"Use of a supplier's language extensions and non-standard-conforming features limits the portability of your code and can prevent you from choosing a new implementation supplier."

I'd love to see this with a little more curation. An example (there are more): calling Inmarsat a startup is a bit tenuous when they are LSE listed with a market cap of 2.8 billion.

This would be a great analogy if countries in grey shared a common language.

The article opens by quoting the NYTimes claiming the iPad's keyboard is "abysmal for typing anything over 140 characters", yet fails to address this point anywhere. Is touch as fast and accurate as a keyboard and mouse?

The key is the same length as the data, making this a one-time pad rather than XOR encryption. http://en.wikipedia.org/wiki/One-time_pad

Presumably you'd have to store the keys somewhere, given that only a savant would be able to memorise them. That somewhere will probably as easy to seize as the encrypted data.
