Both package managers will ask to be regularly updated. This can take some time.

Write a program to find 100 largest numbers out of an array of 1 billion numbers
...ion (the first k numbers are automatically added to the queue). We can use order statistics (see link) to calculate this probability. For example, lets assume the numbers were randomly selected uniformly from {0, 1}, the expected value of (i-K)th number (out of i numbers) is (i-k)/i, and chance of a...

sort -k4nr file.txt
to sort file.txt by column 4 numerically in reverse order. (Though the data in the question has even 5 fields so the last field would be index 5.)

Now, if it turns out that your program is constantly using 100% CPU, and adding more threads just makes it slower, then you'...
Rotating x axis labels in R for barplot
...produce a barplot with qsec colum information
mtcars = mtcars[with(mtcars, order(-qsec)), ] #order mtcars data set by column "qsec"
end_point = 0.5 + nrow(mtcars) + nrow(mtcars) - 1 #this is the line which does the trick (together with barplot "space = 1" parameter)
barplot(mtcars$qsec, col = "gre...

Mythical man month 10 lines per developer day - how close on large projects? [closed]

@mm24 Fourthly, massive performance improvements. F# is orders of magnitude faster than Mathematica and their proof-of-concept code in F# is 5x faster than their production C++ code. This means that tests execute in seconds rather than hours, at which point testing becomes an inte...
What is a mixin, and why are they useful?
