A tool to detect renames, specification

Goal

• Can be used in conjunction with rsync. Executed before rsync to renames files to their new location and rsync can synchronize the rest as it works well for that
• Does detect the file renames that happened in a tree and apply the changes in the other tree

Components:

• a laptop with a file hierarchy to send
• a server that will receive the files

Operation:

• Client generates a unique key pair
• Client configures server to accept files from this public key
• Server advertise itself on bittorrent DHT using hash(this protocol name, "server" role, public key)

Build a fedora kernel rpm

Rationale:

• I need a custom kernel (because sound won't work with vanilla)
• I want to use Fedora Atomic Host
• The only way to override the kernel with Fedora Atomic Host is to install a kernel package using ostree-rpm
• I have a metered network connection and want to avoid downloading the kernel sources too many times
• The powerful machine that can build the kernel is nor running Fedora or Red-hat based system with rpmbuild available

A namespace is a collection of nomad jobs in the same directory. Sub-directories are sub-namespaces. When instanciated, a namespace is allocated an identifier (8 character unique ID). Before being inserted in nomad, the jobs are modified to include this namespace identifier:

• the nomad job name is prefixed by "NAMESPACE-" (the namespace identifier)
• the consul service definitions are prefixed by "NAMESPACE-" (the namespace identifier)
• the services have an additional environment variable: CONSUL_NAMESPACE_ID

sub-namespaces are also inserted in the system when their parent namespace is inserted. Each sub-namespace is given an identifier the same way. The parent namespace is instanciated with:

• an environment variable CONSUL_NAMESPACE_ID_FOR_subnsname containing the sub namespace identifier

TL;DR code linters may be beneficial but may also cause problems. Basically:

• It should be included in the editor plugins and shared as most as possible. Example: I never have to complain when vim reformat my Go source file upon saving it. I did not configure it either, it was automatic.
• automated tools cannot evaluate code complexity, only give metrics that may or may not represent complexity
• code complexity depends on how people read the code

Code complexity

Code is complex when understanding what it does, reading it, becomes complex. Thus it depends on how people are reading the code. One thing that makes code complex is when you have to browse to different locations/files when reading the code. Another thing that makes reading difficult is when code is not well organized and you struggle to find a piece of code.
