Understand the “Decorator Pattern” with a real world example
...encryption standard. Similarly, in a system you can have the encryption as AES - Advance encryption standard. Also, you can have the combination of encryption - First DES, then AES. Or you can have first AES, then DES.
Discussion- How will you cater this situation? You cannot keep creating the obj...
Ignore outliers in ggplot2 boxplot
...rnorm(100), 100))
# create boxplot that includes outliers
p0 = ggplot(df, aes(y = y)) + geom_boxplot(aes(x = factor(1)))
# compute lower and upper whiskers
ylim1 = boxplot.stats(df$y)$stats[c(1, 5)]
# scale y limits based on ylim1
p1 = p0 + coord_cartesian(ylim = ylim1*1.05)

Plotting two variables as lines using ggplot2 on the same graph
...of variables, you can build the plot manually yourself:
ggplot(test_data, aes(date)) +
geom_line(aes(y = var0, colour = "var0")) +
geom_line(aes(y = var1, colour = "var1"))

Java 256-bit AES Password-Based Encryption
I need to implement 256 bit AES encryption, but all the examples I have found online use a "KeyGenerator" to generate a 256 bit key, but I would like to use my own passkey. How can I create my own key? I have tried padding it out to 256 bits, but then I get an error saying that the key is too long. ...
Overlaying histograms with ggplot2 in R
...
Your current code:
ggplot(histogram, aes(f0, fill = utt)) + geom_histogram(alpha = 0.2)
is telling ggplot to construct one histogram using all the values in f0 and then color the bars of this single histogram according to the variable utt.
