Good example of livelock?
...uld wait.
The proper fix is to always respect the lock heirarchy. Pick an order in which you acquire the locks and stick to that. For example if both threads always acquire lock1 before lock2, then there is no possibility of deadlock.

Difference between Statement and PreparedStatement
...ons to the server is faster. As a rule of thumb network operations are an order of magnitude slower than disk operations which are an order of magnitude slower than in-memory CPU operations. Hence, any reduction in amount of data sent over the network will have a good effect on overall performance...

What is the best way to compute trending topics or tags?
... Addition
Normal z-scores as discussed above do not take into account the order of the data and hence the z-score for an observation of '1' or '9' would have the same magnitude against the sequence [1, 1, 1, 1, 9, 9, 9, 9]. Obviously for trend finding, the most current data should have more weight ...

...lest solution is to sort before comparing:
Enumerable.SequenceEqual(list1.OrderBy(t => t), list2.OrderBy(t => t))
Edit:
Here is a solution that performs a bit better (about ten times faster), and only requires IEquatable, not IComparable:
public static bool ScrambledEquals<T>(IEnume...

One more reason for strange conversion errors: Order of execution!
SQL-Server is well know to do things in an order of execution one might not have expected. Your written statement looks like the conversion is done before some type related action takes place, but the engi...
How do you get the index of the current iteration of a foreach loop?
...index is beside the point. Additionally, that the linked list does have an order only strengthens Jim's position. All you need to do is number each element in order. Specifically, you can achieve this by incrementing a count while you iterate, or you could generate a list of integers with the same l...

mongodb/mongoose findMany - find all documents with IDs listed in array
... Kind of late to this discussion, but how would you ensure the order of the items returned matches the order of the array of items you provide in the array? Documents are not guaranteed to come out in any order unless you specify a sort. What if you want them sorted in the same order you...
