I was always curious how hashing functions were implemented, so I read about the
"polynomial rolling hash function", and I decided implementing it would be a
good exercise. After writing that, writing a hash table was simple.
Write a function to modify an array of integers in-place such that all of the
zeroes in the array are at the end, and the order of the other integers is not
changed.
This solution operates in O(n) time instead of O(n*log(n)) time, which
surprisingly isn't *that* big of a difference...
Consider a size of n of 10M...
1) ~10s
2) ~0.5s
So, yes, the O(n*log(n)) will take 100x longer to complete, but for an enormous
input size of 10M elements, it can still complete in under a minute. The
difference between that and the second, faster, algorithm, is just 9s.
Write a function that reads a string of compressed XML and outputs the
decompressed version.
Note to self: Now that I'm growing more comfortable writing parsers, I'd like to
become equally comfortable writing pretty-printers.
After a five year hiatus, I decided to attempt to solve the famous N queens
problem again. This time, instead of modeling the chess board using a
`[[Bool]]`, I'm using `[Integer]` where the `Integer` indicates which column has
a queen. This is a bit lighter in RAM.
- The new PANETTONE.IRC package contains the SEND-IRC-NOTIFICATION function,
which opens a new TCP socket to irccat (if it's running and configured) in
order to announce the creation of new issues.
- The IRCCATHOST and IRCCATPORT environment variables must be set for this to
work.
- Additionally, the ISSUECHANNEL environment variable may be used to direct
announcements at a given channel (otherwise it'll just use the first one).

This module configures irccat by creating a JSON configuration file
from a user-supplied Nix struct (this is not checked for correctness),
and merging it recursively with secrets from
`/etc/secrets/irccat.json` at service launch time.
This way we get the ability to configure (most) options declaratively
via Nix, while providing the secrets outside of Nix.
Side note: We need to figure out a secrets distribution mechanism.
Tested: Wrote a dummy config in whitby/default.nix locally and checked
that this builds, but I have not actually run the service yet. I
expect that some minor tweaks will end up being necessary.

Extends storage.Persist to accept a Content-Type argument, which in
the GCS backend is persisted with the object to ensure that the object
is served back with this content-type.
This is not yet implemented for the filesystem backend, where the
parameter is simply ignored.
This should help in the case of clients which expect the returned
objects to have content-types set when, for example, fetching layers
by digest.
Considered adding hswaw, but after q3k left it'd be a single edge, so
perhaps no point.

To ensure that registry clients which attempt to pull manifests by
their content hash can interact with Nixery, this change implements
persisting image manifests in the CAS in the same way as image layers.
In combination with the previous refactorings this means that Nixery's
serving flow is now compatible with containerd.
I have verified this locally, but CI currently only runs against
Docker and not containerd, which is something I plan to address in a
subsequent PR.
This fixes#102
Modifies the layer serving endpoint to be a generic blob-serving
endpoint that can handle both manifest and layer object "types".
Note that this commit does not yet populate the CAS with any
manifests.
There's just not enough juice in this machine to run more than one.
