Random number generation in C++11: how to generate, how does it work? [closed]
... MyRNG; // the Mersenne Twister with a popular choice of parameters
uint32_t seed_val; // populate somehow
MyRNG rng; // e.g. keep one global instance (per thread)
void initialize()
{
rng.seed(seed_val);
}
Now we can create distributions:

Python concatenate text files
...path/to/output/file', 'w') as outfile:
for line in itertools.chain.from_iterable(itertools.imap(open, filnames)):
outfile.write(line)
Sadly, this last method leaves a few open file descriptors, which the GC should take care of anyway. I just thought it was interesting

];
gulp.task('move',['clean'], function(){

PHP Session Fixation / Hijacking
...it's done by giving them a url like http://www.example.com/index...?session_name=sessionid. Once the attacker gives the url to the client, the attack is the same as a session hijacking attack.
There are a few ways to prevent session fixation (do all of them):
Set session.use_trans_sid = 0 in your...

The most straight forward "solution"
flPanel.Controls.AddRange(_list.AsEnumerable());
Now since you are covariantly changing List<LinkLabel> to IEnumerable<Control> there is no more concerns since it is not possible to "add" an item to an enumerable.

Delete an element from a dictionary
... use an an already constructed dict without a single item as **kwargs, some_function(**{k:v for k,v in some_dict.items() if k not 'some_key'})

Is it smart to replace boost::thread and boost::mutex with c++11 equivalents?
...not
C++11 supports std::async, but Boost does not
Boost has a boost::shared_mutex for multiple-reader/single-writer locking. The analogous std::shared_timed_mutex is available only since C++14 (N3891), while std::shared_mutex is available only since C++17 (N4508).
C++11 timeouts are different to Boo...

Range: products-by-date=2009_03_27-

Range: products-by-date=0-2009_11_30
to get all products older than that date. '0' is probably not best solution, but RFC seems to want something for range start. There...
How to convert Java String into byte[]?
...(Charset.forName("UTF-8"));
byte[] b = string.getBytes(StandardCharsets.UTF_8); // Java 7+ only
However the problem you appear to be wrestling with is that this doesn't display very well. Calling toString() will just give you the default Object.toString() which is the class name + memory address...
