Ellipsis and slice are used for slicing. e.g: class MyContainer(object): def __getitem__(self, key): return key >>> c = MyContainer() >>> c[1] 1 >>> c[1:] slice(1, None, None) >&

Nice and concise. It would be complemented nicely by a list of Python "gotchas". E.g., off the top of my head, mutable default arguments, or trying to catch multiple exceptions with "except Exception1, Exception2:". That

They don't mention the exact charges, but I think it's safe to assume that's the maximum sentence for the charges. So "terrorist threats with nothing to back it up" aren't necessarily worth 8 years in prison, b

"subsidising travellers"? If anything the travellers must be subsidising the non-travellers now. A couple of megabytes of data do not cost hundreds of dollars to move just because you have to route through one more network.

I do mean the hash function "SHA-512/256", as defined in FIPS 180-4 [1]. It is basically a version of SHA-512 that truncates the final result to 256 bits (Like SHA-384). It is not vulnerable to length extension, because unlike SHA-256, the

It does matter what hash function you use, though. MD5 and SHA-512 are both vulnerable to length extension, but there are other hash functions that are not, like SHA-512/256, SHA-3 or BLAKE. The documentation for both Keccak and BLAKE2 reco

Unless I'm missing something, the example code will just calculate the checksum of "key:value&key:value&key:value", so actually anything with the same number of parameters will pass. Assuming "key:value" is supposed to read "#{key}:

That would require the CPU to currently be using at least 33% of the laptop power on average, which sounds high. My phone is currently reporting 30% on wifi and 24% on the display - and this is a small screen device that spends most of its

Oh, wow. I had assumed that people who visited around the same time got the same next page URL, maybe as part of a caching strategy or something. This way seems impractical, TBH. Certainly for the user - the expiration a bit of a nuisance,

That doesn't sound too different from finding and exploiting a bug in an online bank. If e.g. someone found a way to log in as other users, that would reflect poorly on the bank's security, but it wouldn't entitle them to withdraw all the m

They're not actually being sued, are they? That part seemed a bit dishonest to me. It looks like so far they have only been served a particularly obnoxious cease and desist letter.

My impression was that TokuDB is a single-server database, as a backend for MySQL. In that case it wouldn't be a direct competitor to HBase and Cassandra, both of which you normally wouldn't even consider unless you expect to have a cluster

These are all reasons why you'll do fine with MySQL if you're stuck with it, but they don't give a compelling reason to choose MySQL over e.g. PostgreSQL. One thing I like about MySQL is the support available from third parties like Percona
