Bash: infinite sleep (infinite blocking)
...p infinity), hence the best you can do probably is:
while :; do sleep 2073600; done
(Note that I believe sleep loops internally for higher values than 24 days, but this means: It is not blocking, it is very slowly looping. So why not move this loop to the outside?)

The Directory Performance drops by 60% between 120 and 1000 Directories.
Values for Numbers > 1000 remain relatively stable
Interestingly the Number of Directories and Files do NOT significantly interfere.
So the Lessons are:

What is the recommended batch size for SqlBulkCopy?
...ult is 30 seconds. You might try doubling the BulkCopyTimeout property to 60 seconds. This allows a longer period of time for a larger set of batch rows to be copied. For example, a batch of 50,000 rows might take around 40 seconds just exceeding the 30 seconds time limit so bumping it up to 60 s...
A simple explanation of Naive Bayes Classification
...number of RED objects / total number of objects
Since there is a total of 60 objects, 40 of which are GREEN and 20 RED, our prior probabilities for class membership are:
Prior Probability for GREEN: 40 / 60
Prior Probability for RED: 20 / 60
Having formulated our prior probability, we are now re...
