|How to measure length of generator sequence (list comp vs generator expression)|
| by Brian in Programming Languages|
I have a generator that generates a finite sequence. To determine
the length of this sequence I tried these two approaches:
seq_len = sum([1 for _ in euler14_seq(sv)]) # list comp
seq_len = sum(1 for _ in euler14_seq(sv)) #
sv is a constant
starting value for the sequence.

|Hibernate: can I override an identifier generator using XML with a custom generator?|
| by Jules in Programming Languages|
I want to use a custom sequence generator in my application, but the
entity is located in a domain model jar that is shared with other
applications. Apparently entity annotations can be overridden in
orm.xml but I can't figure out the proper XML incantation to
get this to work.
I can modify the annotation in the entity

|Homemade Wind Generator Using an Automobile Generator|
| by Charlie98 in Hobbies, Games & Toys|
You can make a homemade wind-powered generator with no special training.
Many of the parts you need can be cannibalized from other equipment. You
can even use an old car generator, more frequently called an alternator.
FunctionWwind pushes against the blades of the turbine, causing them to
rotate. This in turn rotates the generator they are hooked up to, causing
it to produce electricity.

I would like to know how to write python function which can flatten

|Pseudorandom Sequence Generator not just a number generator|
| by Kbotei in Web Design|
I need an algorithm that pretty much will turn a unix timestamp into a
suitably random number, so that if I "play back" the timestamps I get the
same random numbers.
And here's what I mean by suitably:
Most humans will not detect a loop or pattern in the random numbers.
It need not be cryptographically secure.
All numbers must be capable
of being generated. (I've

|How to Install a Generator in a Generator Ready RV|
| by FriendL in Cars|
Recreational vehicles are most effective as self-contained units when
equipped with an onboard power source capable of providing 120-volt AC
power. This is the purpose of a generator. Installing the generator into a
cargo bay obviates the need for a bumper mount or for constant loading and
unloading. It reduces this expensive accessory's vulnerability to weather
damage, vandalism and theft. 'Gener

|Error Using Ruby generator in Rails (not Rails::Generator)|
| by language-agnostic in Programming Languages|
Edit: To be clear, I'm trying to use this kind of generator (i.e. with a
'yield' statement) not a Rails generator.
I have the following
(simplified) initializer mixin in a Rails project that I could use some
help with. What I wanted to do was create a generator to track Twitter API
calls (this is just for debugging, I know about rate_limit_status).
