+
+* About reproducible builds
+
+ - Packages with the same source code, built with the same toolchain, should come out identical.
+ - reproducible-builds.org
+
+* What lead to the creation of a monster?
+
+ - u-boot was marked as reproducible
+ - I knew it was wrong:
+
+ U-Boot SPL 2016.01+dfsg1-3 (*Feb 21 2016 - 21:39:10*)
+
+ - Handful of arm systems
+
+* Humble Beginnings
+
+ - In August of 2015, work was done to enable two dual-core and two
+ quad-core build machines.
+
+ [[./images/hb2_20160630_021.jpg]]
+
+* It Lives!
+ - In September, the network went live, building around 200 source
+ packages a day.
+ - With over 20,000 packages in the archive, it would take over 100
+ days to build everything in unstable...
+
+* The Monster Grows In Strength and Numbers
+
+ - I bought a couple more boards...
+ - Donation from beagleboard.org of a beagleboard-x15
+ - In December 2015, the Debian Project Leader approved a proposal to
+ triple the capacity of our build network.
+
+ [[./images/bbx15_20160630_012.jpg]]
+
+* Recent Sightings
+
+ [[./images/rack_20160630_010.jpg]]
+
+* Current configuration
+ - Three dual-core, 1gb ram
+ - Two quad-core, 1gb ram
+ - Two dual-core, 2gb ram
+ - Eight quad-core, 2gb ram
+ - Three quad-core, ~4gb ram
+ - Three octa-core, 2gb ram
+
+* How many Whatsits?
+
+ (3*2)+(2*4)+(2*2)+(8*4)+(3*4)+(3*8) =
+
+ *86 cores!!!!*
+
+ (3*1)+(2*1)+(2*2)+(8*2)+(3*4)+(3*2) =
+
+ *43 gb ram!!!!*
+
+* Devouring the archive
+ - Builds about 1400 or more packages a day!
+
+ [[./images/stats_builds_per_day_armhf-2016-06-30.png]]
+
+ - Builds unstable, testing and experimental in around 45 days.
+
+* Building in Power
+
+ - The whole armhf build network runs in under 180 watts!
+
+ [[./images/power/b20160630_029.jpg]]
+
+* Space
+ [[./images/heater_20160702_210953_1.jpg]]
+
+ - A space heater used at debconf16 uses 400-800 watts!
+
+* Hungry for Bandwidth
+
+ June 2016
+ | | received | transmitted |
+ | | | |
+ | firewall | 137.37 GiB | 643.67 GiB |
+ | | | |
+ | proxy | 115.68 GiB | 4.99 TiB |
+
+* Boards of a feather
+
+ - Cubox-i4pro and i4x4
+ - Hummingboard-i2ex
+ - Wandboard Quad and Dual
+ - Firefly-RK3288
+ - Beagleboard-x15
+ - Cubietruck
+ - Bananapi
+ - OrangePI Plus2
+ - Raspberry PI 2
+ - Odroid-XU4
+ - Odroid-U3
+
+* Platforms enabled in the Debian
+ - linux: Odroid-U3, Firefly-RK3288, Odroid-XU4, BeagleBoard-X15
+ - u-boot: Odroid-XU4, Firefly-RK3288, BeagleBoard-X15,
+ Cubietruck plus, OrangePI plus
+ - debian-installer: BeagleBoard-X15, Firefly-RK3288
+
+* Platforms to pout about
+ - lack mainline kernel and u-boot:
+ - Cubieboard4, Odroid-C1+
+ - lack mainline kernel:
+ - Cubietruck plus, Lemaker HiKey
+ - Non-free firmware blobs:
+ - raspberry pi 2, Odroid-U3, Odroid-XU4, Odroid-C1+, Firefly(??)
+ - Mainline u-boot support for all ram:
+ - Firefly-RK3288 4gb variant, Cubox-i4x4
+
+* In December of 2017, the reproducible build network became aware
+
+ - Other boards:
+ - Pine64, Odroid-C2
+ - Lemaker Cello, HP Moonshot
+ - Build archictecture-independent packages on different architecture
+ for first and second build.
+* By 2050...
+ - The Autonomous Reproducible Build Network Produced a bit-for-bit
+ copy of the entire earth.
+* Thanks
+ - Holger for all the work to integrate armhf and continued
+ maintenance of jenkins.debian.net
+ - Hardware donations: Debian, LeMaker, BeagleBoard.org Solid-Run
+ - All the great reproducible builds folks!
