About the Noble Jury
The Noble Jury is a collection of servers and utilities run for the purpose of facilitating community-minded projects. The system operator can be reached at firstname.lastname@example.org, and abuse or DMCA queries should be directed to email@example.com.
Naming and domains
Projects that are deemed "production-worthy" by their maintainer are hosted under the .noblejury.com domain. These projects recieve priority CPU time and the OOM killer is kinder to them. Some of these projects are hosted under their own project-specific domains as well: for example, many UMBC utilities are available through the umbc.in address. All production projects should only be accessible over HTTPS, with the exception of podcasts which are available in HTTP for compatibility reasons. SSL Certificates are graciously provided by Let's Encrypt.
Projects that are not stable enough to be used for production are hosted under one of the user domains, for example Cataloguer [opds.lin.anticlack.com] (an OPDS HTTP browser). User domains take the form of [projectname].[username].anticlack.com, and may or may not be HTTPS-secured. A notable exception to this name scheme is download.lin.anticlack.com, which is a static file host that is granted production privileges in terms of resources but not HTTPS secured for performance reasons.
The Jury uses NGINX as a frontend load balancer, with most projects using Postgres as the database. uWSGI manages all python web services and some Perl/Dancer applications. The FastCGI Process Manager coordinates the PHP process pools. Huginn and Ganglia (formerly a function provided by Munin) are the main automation and monitoring tools respectively. Mail is provided by Postfix and Dovecot with alpine and alpine-web as the standard clients for command-line and web access. SoGO is also provided as a groupware solution. Access to the server is done over SSH with public-key encryption only, with MOSH supported as a persistent process. Single Sign On is available for many services using oauth2_proxy.
The Jury is composed of the presiding host, sonika, vitrix, and the jurors. Expansion is planned to include another upstream host in the upcoming months.
The presiding host is a Linode 4GB VPS with 4GB RAM (2GB zram) and 2 Xeon CPU E5-2680 v2 cores @ 2.80GHz running Arch Linux. A fast storage solution on this host is provided by dedicating 100MB of RAM to application transient cache, with longer-term storage backed by Google Drive via rclone. Backups are taken hourly to several locations. This host is the primary public-facing presence for the Jury.
Sonika is a Yoga 2 Pro laptop running Arch Linux, which is connected by persistent reverse SSH tunnel to the presiding host. This node is used for nightly batch jobs and has a mirror of the application disks for failover.
Vitrix is a NAS share that is used for medium speed network storage (i.e. slower than local disks, faster than Google Drive). This node is used for serving mirrored content.
The jurors are IBM T43p laptops with around 1GB RAM and a Pentium M processor clocked @ 1.86GHz running Arch Linux 32. These hosts serve as low powered job slaves. Currently, two jurors are online, Lavavoth and Xgazd.
The yet unnamed upstream host will be an HP DL360 G6 with 12GB RAM and a Xeon E5504 @ 2GHz. This host will replace Vitrix as the primary disk pool, as well as provide GPU support for video transcoding and additional resources for development domains, including a read-only Postgres slave and a small read-write Postgres sandbox database. This host will also be used as the primary continuous integration testing host.
