What are the underlying data structures used for Redis?
...rios where you want to store an HTML page, but also when you want to avoid converting your already encoded data. So for instance, if you have JSON or MessagePack you may just store objects as strings. In Redis 2.6 you can even manipulate this kind of object server side using Lua scripts.

Exotic architectures the standards committees care about
...ters (including void*) always had the same size. (Of course, you couldn't convert a function pointer to void*, since void* might be smaller. But according to the standard, you can't do that today, either.)

What is the difference between a strongly typed language and a statically typed language?
...he type system. C is notoriously weakly typed because any pointer type is convertible to any other pointer type simply by casting. Pascal was intended to be strongly typed, but an oversight in the design (untagged variant records) introduced a loophole into the type system, so technically it is we...
How does this print “hello world”?
... symbols) = 127 possible values, which can be represented with 7 bits.
We converted each UTF-8 (16 bit) character to 7 bits, and gain more than 56% compression ratio. So we could send texts with twice length in the same number of SMSs. (It is somehow the same thing happened here).

This converts the absolute times to seconds:

static const uint64_t NANOS_PER_MSEC = 1000ULL * NANOS_PER_USEC;

.NET unique object identifier
...erence is the unique identifier for the object. I don't know of any way of converting this into anything like a string etc. The value of the reference will change during compaction (as you've seen), but every previous value A will be changed to value B, so as far as safe code is concerned it's still...
