Interesting... If I prepend `(bytes #x78 #x9c)` to the compressed data created
by deflate, zlib-flate will uncompress it. Same thing happens in reverse where
I skip the first two bytes of the zlib-flate'd data and process it with inflate.

Perhaps you should use `gunzip-through-ports` which also parses the required
header?

I'm looking at some data that was zlib compressed and I thought I'd inflate it
with file/gunzip's deflate function, but I get "inflate: error in compressed
data". I thought to try from the opposite direction, grabbing some deflated
data from Racket and then asking zlib-flate to inflate it again,
I'm not sure about splicing-let-syntax, but if that doesn't work, you
could also try using local expand and drop the bindings on the
right-hand side of any definitions you find.

Change how local variables compile at the prompt that's inside the
debug repl? You should have the complete set of them, I think. Compile
them into looking into a table other than the namespace.

Hello,
I want to shadow instead of mutate.
The ideal solution would be to create a new environment that extends the old
one, so that new definitions in the new environment shadow the old definitions
instead of mutating them.
But if that isn't feasible with the way namespaces work right now, i
For the app that you're using, can you provide a histogram of the
inputs that you supply to number->string or, if it isn't too much
trouble, point me at the app so I can grab that?

Also, if you have something like this:

you should see the word `future` linked to the docs. (And, if you had

The short answer is ‘no.’ It’s in the print queue with MIT P and they will
bring out paper book this year. They also own all other electronic publication

Hello
I was wondering if the second edition of How to Design Programs was available
in a download format, and if so where can I find it.
The issue that I am having is that I spend a good part of my day in an
environment with little to no cell or Internet services, and it would be a lot
easier
I've made a package with two map implementations that use parallelism. "pmapf"
use futures and "pmapp" use places, I would like to get some feedback and
thoughts about it.
You can install it through the DrRacket package manager.

Thanks a lot! Retryers are fantastic. I have poorly written this code more
than a few times and I like the model a lot.
