Which parts of Real World Haskell are now obsolete or considered bad practice?
...ity
type Reader r = ReaderT r Identity
So they're defined by their monad transformer.
Chapter 17. Interfacing with C: the FFI
The overall chapter is fine, but as one can read in the comments or on Yuras Shumovich's blog, the finalizer part in the following code is bad practise:
pcre_ptr <- c...
How can I plot with 2 different y-axes?
...function(vec, lims=range(vec), clip=c(0, 1)) {
# find the coeficients of transforming linear equation
# that maps the lims range to (0, 1)
slope <- (1 - 0) / (lims[2] - lims[1])
intercept <- - slope * lims[1]
xformed <- slope * vec + intercept
# do the clipping
xformed[xform...
Why are side-effects modeled as monads in Haskell?
...uments, or from libraries, respectively), construct no-ops with return, or transform a value in an irreversible manner using (>>=). The essence of programming in an arbitrary monad is generating a list of irrevocable actions: "do X, then do Y, then...". Sounds pretty imperative to me!

...uctor, wrap the std::initializer_list<rref_capture<T>> in some transformation trait of your choosing - say, std::decay_t - to block unwanted deduction.

How do HTML parses work if they're not using regexp?
...
Parsing HTML is the transformation of a linear text into a tree structure. Regular expressions cannot generally handle tree structures. The regular expression you need at each point to get the next token changes all the time. You can use regu...
How can I get a view's current width and height when using autolayout constraints?
...ght (or the frame, which is equivalent unless you're playing with the view.transform).
If what you want is the width and height implied by your existing constraints, the answer is not to inspect the constraints manually, since that would require you to re-implement the entire constraint-solving log...
What's wrong with using $_REQUEST[]?
...nsidered harmful for the same reason that simple-to-medium-complexity data-transformations are often performed in the application code instead of declared in SQL: some programmers suck.
As such, if one tends to use $_REQUEST everywhere, I can do anything via GET that I could via POST, which means s...
How to create a memory leak in Java?
...painful memory leaks in the JEE world, often caused by 3rd party libs that transform data (BeanUtils, XML/JSON codecs). This can happen when the lib is loaded outside your application's root classloader but holds references to your classes (eg. by caching). When you undeploy/redeploy your app the ...
