How can I find a specific element in a List?
...
Use a lambda em>x m>pression
MyClass result = list.Find(m>x m> => m>x m>.GetId() == "m>x m>y");
Note: C# has a built-in syntam>x m> for properties. Instead of writing getter and setter methods (as you might be used to from Java), write
private string _id;...
Math - mapping numbers
...
If your number m>X m> falls between A and B, and you would like Y to fall between C and D, you can apply the following linear transform:
Y = (m>X m>-A)/(B-A) * (D-C) + C
That should give you what you want, although your question is a little ambigu...
Shading a kernel density plot between two points.
...nd I believe we had similar questions here too.
You need to find the indem>x m> of the quantile values to get the actual (m>x m>,y) pairs.
Edit: Here you go:
m>x m>1 <- min(which(dens$m>x m> >= q75))
m>x m>2 <- mam>x m>(which(dens$m>x m> < q95))
with(dens, polygon(m>x m>=c(m>x m>[c(m>x m>1,m>x m>1:m>x m>2,m>x m>2)]), y= c(0, y[m>x m>1:m>x m>2], 0), col=...
What is the difference between persist() and merge() in JPA and Hibernate?
...avadoc:
The semantics of the persist
operation, applied to an entity m>X m> are
as follows:
If m>X m> is a new entity, it
becomes managed. The entity m>X m> will be
entered into the database at or before
transaction commit or as a result of
the flush operation.
If m>X m> is a
preem>x m>isting ma...
How to catch integer(0)?
... length integers, then you want something like
is.integer0 <- function(m>x m>)
{
is.integer(m>x m>) && length(m>x m>) == 0L
}
Check it with:
is.integer0(integer(0)) #TRUE
is.integer0(0L) #FALSE
is.integer0(numeric(0)) #FALSE
You can also use assertive for this.

Scala constructor overload?
...
It's worth em>x m>plicitly mentioning that Aum>x m>iliary Constructors in Scala must either call the primary constructor (as in landon9720's) answer, or another aum>x m>iliary constructor from the same class, as their first action. They cannot simply c...
How to do a PUT request with curl?
...
Using the -m>X m> flag with whatever HTTP verb you want:
curl -m>X m> PUT -d arg=val -d arg2=val2 localhost:8080
This em>x m>ample also uses the -d flag to provide arguments with your PUT request.

You can override ggplots default scales by modifying scale_m>x m>_continuous and/or scale_y_continuous. For em>x m>ample:
library(ggplot2)
dat <- data.frame(m>x m> = rnorm(100), y = rnorm(100))
ggplot(dat, aes(m>x m>,y)) +
geom_point()
Gives you this:
And overriding the scales can give you s...
Is it a bad practice to use break in a for loop? [closed]
...e nested sub-blocks, yes, you could easily forget that some code won't be em>x m>ecuted after the break. If, however, the loop is short and to the point, the purpose of the break statement should be obvious.
If a loop is getting too big, use one or more well-named function calls within the loop instead....
how do I make a single legend for many subplots with matplotlib?
...ies, with multiple subplots with matplotlib. That is, I have 9 plots on a 3m>x m>3 grid, all with the same for lines (of course, different values per line).
