DESCRIPTION:Speaker: Bruno Cornec\nThese days\, most people speaking APIs 
 think REST API. It's ubiquitous\, uses standard protocols and formats\, ba
 sed on giants shoulders...\nFor the sysadmin REST API like Redfish is a ni
 ce way to have a cross-manufacturer out of band management interface e.g.\
 n\nHowever in some case\, you have constraints that do not allow you to us
 e a REST API. When your system is not reachable directly using the HTTPS p
 rotocol e.g.  In that case\, you can still use an API of course\, but base
 d on other standards\, such as the venerable STMP one !\n\nOur use case\, 
 a training on demand workshop system\, involves a Web front-end to manage 
 user registration to run jupyter notebooks hosted on a back-end hosting th
 e jupyterhub instance as well as all the companion systems needed to perfo
 rm the various workshops proposed (on Redfish\, Git\, Rust as visible on h
 ttps://hackshack.hpedev.io/workshops)\n\nSo to make it work flawlessly\, w
 e used an SMTP based API\, the front-end generating the SMTP content and t
 he back-end using procmail\, some scripts and ansible playbooks to manage 
 the setup of the user environment. Once logged on the platform\, the user 
 has acces to its own workshop content\, with all the links to the other sy
 stems available to perform the actions. Why SMTP ? Well our needs were sma
 ll enough to avoid developing a full REST one (even if if have also one fo
 r the front-end)\, we benefit from the asynchronous aspect of e-mail for f
 ree in the management of requests\, and it's fun to use old methods to sho
 w young engineers that there is more than one way to do it \;-)\n\nInteres
 ted ? Well come to hear how we did that and we'll show you how it works\, 
 from the automatic deployment of the platform up to the run of a workshop.

DESCRIPTION:Speaker: Tishampati Dhar\nThe Digital Earth Australia and Digi
 tal Earth Africa programs host and process very large volumes of open data
  on cloud infrastructure using primarily Kubernetes as an orchestration me
 chanism. The project is run out of an Australian government agency\, Geosc
 ience Australia\, and as such\, this infrastructure needs to meet the [Ess
 ential-8](https://www.cyber.gov.au/acsc/view-all-content/essential-eight/e
 ssential-eight-explained) security mitigation requirements.\n\nThis talk p
 resents the difficult balancing act of meeting the security needs of an op
 enaccess\, open data and open source platform. The principal workloads on 
 this infrastructure include web applications\, petabyte scale data process
 ing and cross-continent data movement. Part of this platform enables scien
 tific experimentation\, which essentially allows arbitrary code execution 
 too. Recent statistical operations on year-long continental Satellite imag
 ery time-series for Africa consumed 4\,000 CPUs and 50 TiB of RAM across 2
 00 nodes.\n\nThe infrastructure is mostly codified and open sourced [here]
 (https://github.com/opendatacube/datacube-k8s-eks) as terraform modules. A
 pplications are deployed via [Helm Charts](https://github.com/opendatacube
 /datacube-charts) and scanned using [Trivy](https://github.com/aquasecurit
 y/trivy). The network within the cluster and to the outside is filtered us
 ing [Cilium](https://cilium.io/). Deployments are automated and audit-logg
 ed via GitOps and [Flux](https://github.com/fluxcd/flux).\nThe ability for
  users to self-signup and run arbitrary code occasionally leads to some cy
 cles being lost to Monero. This talk will cover general security principle
 s as well as specific security incidents and mitigation actions taken in r
 esponse.\n\nIn conclusion\, our stack meets Australian Government security
  practice\, while enabling very large workloads to be executed in a flexib
 le\, on-demand computation environment that empowers scientific users. Thi
 s talk will tell you how we do it.

DESCRIPTION:Speaker: Curtis Millar\nShell scripts in all their incarnation
 s have been the go-to for constructing portable glue that interacts with o
 ther scripts and programs. With the evolution of UNIX\, the introduction o
 f the POSIX Shell Command Language gave us a standardised shell language t
 he is the most common mechanism for distributing code to operate in the mo
 st diverse of situations.\n\nWhilst many shell implementations extend upon
  this standard to make it more usable\, this talk will see how we can prod
 uce more expressive programming primitives to allow for truly composable a
 nd portable shell scripts\, showing what the true power of the POSIX shell
  standard is\, where the pain points lie\, and why this standard is ultima
 tely restricted in what it can provide.\n\nGiven the amount of effort requ
 ired to make shell scripts that are both portable and reusable\, we'll als
 o discuss when you should reach for a shell script and when its best to re
 ach for something more powerful\, even if that power brings problems of it
 s own.

DESCRIPTION:Speaker: Sumana Harihareswara\nWhen an open source project has
  gotten stuck\, how do you get it unstuck? Especially if you aren't alread
 y one of its maintainers? My teams have done or are doing this with Mailma
 n\, PyPI\, pipenv\, and Autoconf\, and I have some lessons to share. It is
  even possible for a new contributor\, who's never worked on a project bef
 ore\, to show up and be the catalyst that revives a project or gets a long
 -delayed release out the door. I'll share a few case studies\, principles\
 , and gotchas.\n\nThere's also a larger context here\; why do projects get
  stuck in the first place? Why do so many widely used\, multi-contributor\
 , reasonably important free and open source software projects find themsel
 ves years behind their intended release schedules\, or caught between lega
 cy maintenance burdens and the effort of a much-needed architectural overh
 aul\, or stifled by simmering and unresolved interpersonal disagreements? 
 I propose that a key factor here is the lack of prior management experienc
 e and skill among many FLOSS project maintainers. Individual contributors 
 who have never managed public-facing projects before are often in dire nee
 d of project and product management skills -- and may not realize it. I'll
  discuss that problem\, the particular set of skills maintainers often nee
 d and don't have\, and various initiatives -- including my own upcoming bo
 ok -- to teach those skills.\n\nMore than developer time\, maintainership 
 -- coordination\, leadership\, and management -- is a bottleneck in softwa
 re sustainability. You'll come away from this talk with steps you can take
 \, in the short term and in the long run\, to address this for projects yo
 u care about.\n\nMore information and resources are available at https://w

DESCRIPTION:Speaker: Jordan Niethe\nIn the Linux kernel there are many tim
 es where we need to examine\, manipulate and patch instructions\, which is
  of course deeply tied to the instruction set of each architecture.\nLike 
 any good RISC architecture\, Power has had a fixed instruction size. That 
 only gives you so much space to play with\, and we were running out of roo
 m.\nPower10 presents a solution to that by introducing a new class of inst
 ructions which are twice as long.\nThis means our faithful "unsigned int" 
 is no longer going to cut it as our instruction type and raises questions 
 as how both types of instructions should be represented. Can we move to us
 ing "unsigned long"? Or a struct? How will this impact 32 bit and 64 bit s
 ystems? What about little and big endian ones? Do we have to change anythi
 ng at all?\nWe will see how the mailing list's form of dialectic helps ans
 wer these questions.

 bsystems<\, we want to identify them: We are interested of what subsystems
  the kernel actually consists of and how they are related to each other. T
 his is helpful for newcomers\, to get a better insight in the kernel\, but

 his promises benefits for developers and the community. But beyond this\, 
 a precise documentation and definition of subsystems is also necessary for
  upcoming challenges like certifications in safety critical environments (
 for instance\, as aspired by the Linux Foundation's ELISA project). Proper

 Therefore\, we decided to take a look at the bigger picture. Quite literal

 It measures intersections of responsibility for MAINTAINERS entries\, and 
 clusters them based on overlap intensity\, effectively detecting de-facto 
 subsystems. It reveals sensible\, though sometimes surprising\, structures
 \, compares the differences between de-facto and documented subsystems\, a

DESCRIPTION:Speaker: Mark Eaton\nI recently built a web application called
  the Open Journal Matcher (https://ojm.ocert.at)\, which is a recommender 
 tool for academics looking to find a suitable scholarly journal for their 
 work. The Open Journal Matcher allows users to paste in a draft abstract\,
  which it then compares with the abstracts of over 5600 journals from the 
 Directory of Open Access Journals. The application then returns the top fi
 ve suggested matches\, which are meant to be both relevant and serendipito
 us. This can be very useful to anyone trying to find an appropriate journa
 l for their work.\n\nWhile there are other journal matching services avail
 able\, to my knowledge this is the only one that is both fully interdiscip
 linary and fully open source. The code for the matcher application\, the c
 ode for the matching algorithm\, and the content of the journals\, is all 
 openly licensed. \n\nUpon its release in June 2020\, the OJM received a ve
 ry favorable reception from the open scholarship and scholarly communicati
 ons communities. It has been shared widely by on many platforms. For me\, 
 this has reaffirmed the need for such a tool\, and has led me to focus on 
 its further development.\n\nThis presentation will describe insights glean
 ed while building this tool. I’ll describe the challenges of gathering j
 ournal data from the Directory of Open Access Journals’ API at scale\; t
 he numerous lessons learned while using natural language processing tools 
 to calculate the similarity of texts\; and the difficulties processing lar
 ge amounts of data very quickly for the web using Google Cloud Platform an
 d asynchronous Python programming.\n\nThis project also raises important q
 uestions about the ethics of algorithmic decision making. As technologists
 \, how do we critically evaluate the algorithms that we use when we solve 
 practical programming problems? How do we communicate the trade-offs and c
 hoices we make to stakeholders in our communities who rely upon the tools 
 we build? And how do we ensure that feedback from our communities always c
 omes first in shaping those tools\, so that they most help the people we a
 re serving?\n\nThis presentation will be of interest to authors who are lo
 oking for a journal to publish their scholarly work. It will also be relev
 ant to technologists who are interested in building open source tools for 
 their communities. It will be helpful to librarians who promote scholarly 
 communications\, and who may find this tool to be a useful addition to the
 ir toolkit. Lastly\, it will serve as an interesting example of the novel 
 services we can provide to our communities when we apply open digital tech
 nologies in support of our scholarship.

  Certain structures and norms can make it hard to implement positive chang

 how we'll create a culture that values both experience and institutional m

 rse it is! But ask any programmer you know how much they know about the te
 chnical implementations of how humans observe or operate in space? They'll
  likely be unable to tell you much. Because this is a domain entrenched in
  hardware and communications technologies we developers don't have to inte
 ract with often\, if at all\; to many\, domain-specific hardware in a scie
 nce like astronomy may as well be magic. But the same can be true for the 
 other side\; many of the highly technical personnel working in the space s
 ciences--from astrophysicists to communications engineers--often know soft
 ware practices only as far as it is required to construct scripts or maint
 ain single libraries to run a pipeline whose parameters or requirements so
 metimes won't change for decades. Herein lies an interdisciplinary domain 
 ripe for collaboration or specialisation.\n\nThis talk is a high-speed cra
 sh course in the some of the key data formats\, units and terminology used
  in the domain of radio astronomy--particularly the kind of near-Earth obs
 ervation that has become so critical to our mitigation of the ever-impendi
 ng space debris crisis--for those from a software background. But there wi
 ll be no circuit diagrams here\; let's approach the topic with less maths 
 and more drawings and mad gesturing\, and to tell the great story of space
  observation that led us to this point and its impact on practices (partic
 ularly software practices) still in use today. \n\nFrom the technical and 
 socio-political determinants of core components like units of measurement 
 and the conflicting standards for their conversion\, to the slightly incor
 rect application of open source paradigms and the prevalence of sole maint
 ainers. From the original FORTRAN\, QBASIC and C libraries that still unde
 rlie the majority of this domain\, to the costs of opting for one of the m
 odern Python alternatives. And with a special focus on the particularities
  of Australia's own radio telescopy capabilities and publicly available re
 sources.\n\nIn this tale of off-by-one errors and spherical trigonometry t
 here is fun and humour to be found\, as well as tools and lessons you can 
 use to start delving into hard space science problems from your own comput
 er: such as tracking satellite passes\, interpreting analog-first telescop
 e imagery\, measuring the efficacy of different space surveillance systems
 \, and more! All you need is some Python (or your own favourite language)!

 h and complexity of BPF programs are also increasing.  That\, combined wit
 h the fact that the kernel BPF verifier is getting more and more smart\, a
 llowing more sophisticated programs to run in the kernel\, results in peop
 le wanting to write BPF programs in high-level languages such as C. \n\nFo
 r many years a LLVM port was the only option for BPF developers who wanted
  to write C BPF programs.  A year ago Oracle undertook the task to add a B
 PF port to the GNU Toolchain.  At the present time we have upstreamed supp
 ort for BPF to GCC\, the binutils (assembler\, disassembler\, linker)  the
  GDB debugger and the GNU simulator.  This is work in progress\, and we ar
 e currently in the task of adding support for BTF and CO-RE (Compile once\
 , run everywhere.)\n\nIn this talk we will describe the current status of 
 the port and quickly show how it can be used to do BPF development.

  body of software (adds a feature\, makes a bugfix)\, that developer wants
  to know (and even more important\, the upstream maintainers want to know)
  whether and how it affects system performance.  Too often on the mailing 
 lists I see the phrase 'The performance change is down in the noise'\n\nTw
 o simple statistical tests can be used to determine whether a change is *r
 eally* down in the noise\, or  whether there's a real difference.  Student
 's T test can tell you how likely it is that the mean of two sample sets i
 s the  same\, but it works only on Normal (Gaussian) distributions.  The M
 ann-Whitney U test tells you how likely it is for the median to be the sam
 e\, and works on *any* underlying distribution.\n\nKernel microbenchmarks 
 usually show very  skewed distributions\, where the minimum and the mode a
 re the same\;  but there is a long tail\, with several small modal points 
 in it.\nI've worked out the reason for this\, and how to use the Mann-Whit
 ney U test to determine whether small changes (too noisy to see by eyeball
 ing the resutst) are real or not.\n\nEven though this talk has some statis
 tics in it\, I'm not a statistician\, so it's all stuff that anyone with y

DESCRIPTION:Speaker: Mike Lynch\nArkisto is a project for digital data pre
 servation which focuses on sustainability and reusability\, based on open 
 standards\, taking a data-centric approach.\n\nThe basis of an Arkisto rep
 ository is simply a file system\, with digital artefacts laid out on disk 
 or object storage according to the Oxford Common File Layout standard (OCF
 L)\, which provides efficient versioning and digital preservation features
 . Human- and machine-readable data descriptions are included using RO-Crat
 e\, a format for managing linked data using the JSON-LD and Schema.org sta
 ndards.\n\nDatasets stored in this format can be then indexed using open-s
 ource tools such as Solr or ElasticSearch and made available for search\, 
 discovery and download.\n\nArkisto is intended to address the issue of res
 earch data collections which are no longer being looked after\, due to ins
 titutional changes\, lack of funding or software support. Rather than lock
 ing collections in to a specialised or monolithic repository or database\,
  Arkisto encourages a modular philosophy where the primary object\, the da
 ta itself\, is stored in long-lived formats which are easy to code against
 \, and tools such as indices are relatively cheap to build\, deploy and mo
 dify.\n\nI'll present a short explanation of the key standards and concept
 s behind Arkisto\, and show a couple of applications of its use as a data 
 publication repository at UTS\, and at PARADISEC\, an extensive collection
  of cultural data around endangered languages.

 on some of the other security and performance management capabilities that
   SELinux and CGroups bring to containerised deployments.\n\nTo outline th

   The burden of being watched disproportionately falls on marginalised gro

  becomes far more important to you.  And if your only method of communicat

 rue privacy is a great deal harder to achieve.\n\nIn this talk\, we'll exa

 technology can be exploited to reveal information about its users.  We'll 
 break down ways that disabled people can - and do - avoid tracking and hac
 king\, and find out why paying a 'privacy tax' isn't always feasible for e
 veryone.  Finally\, we'll discuss open-source software that's already redu

 om being signs of the apocalypse\, these have been the sorts of disasters 
 that Free and Open Source Software conference organisers have faced in the
  leadup to their events over the last ten years.\n\nLinux.conf.au in 2011 
 took place in the immediate aftermath of a one-in-forty year flood on the 
 Brisbane River. North Bay Python in 2019 took place amongst nearby mass ev
 acuations and the threat of smoke pollution from nearby bushfires. PyCon U
 S 2020 cancelled an in-person event and rapidly regrouped to produce onlin
 e material\, barely weeks after Coronavirus became widespread in the Unite
 d States.\n\nAll three of these events delivered an event that was signifi
 cantly different to what they had originally planned\, but successfully na
 vigated unexpected circumstances to deliver valuable material and a memora
 ble experience for attendees.\n\nWhile events like conferences are unique 
 in that people (used to) travel to them\, have real deadlines\, and have p
 hysical constraints that online communities don’t have to deal with\, un
 expected crises can affect any project.\n\nThrough interviews with organis
 ers from three disaster-impacted conferences\, we’ll explore common them

  they learned through the process including:\n\n* Maintaining the trust of
  your community through effective and timely communication\n* Developing a

  navigating your commitments with external vendors \n\nThis talk uses conf

 r journey from resistance to adoption of something unthinkable - An FPGA c

 the semiconductor industry.  Companies are demonstrating that you can buil
 d a successful business model based on open source\; just look at the acce
 lerating adoption rate that RISC-V ISA is seeing in the processor space.  
 And yet this is just the tip of the iceberg in terms of how disruptive ope
 n source hardware can become to the semiconductor industry.  \n\nSince the
  inception of our industry\, the vendor-supported FPGA development tools h
 ave been proprietary and closed source. Initially this was simply because 
 that is the way things were done – there were no open standards. But ove
 r time\, keeping them closed and proprietary enabled a level of influence 
 and control over users. If a designer liked your software\, they tended no
 t to change\, and that implicitly makes your user base captive.\n\nOpen so
 urce FPGA tools have been around for a long time\, being used primarily by
  hobbyists and in academia. Over the past few years\, this situation has e
 volved\, with an increasing number of new developers with software backgro
 unds gravitating towards open source FPGA development tools\, including de
 sign teams at some of the largest companies in the electronics industry.\n
 \nSo\, why do FPGA companies still resist them? \n\nNot Invented Here? Fea
 r? Control?\n\nThis talk will serve two purposes:\n1.	To show how one comp
 any is building its future on top of open source FPGA tools\n2.	To share h
 ow we arrived at our decision in the hope that others will soon take the s
 ame leap.

 the home network safe and performant.\nConsumer routers suck: in performan
 ce\, connection reliability\, security\, and ability to have a sane config
 uration.\nOpenWRT and DD-WRT are nice\, but sometimes one has this weird u
 rge to just do it again\, from scratch and using open bits whereever possi
 ble.\nMaybe just because.\n\nAnyway\, I decided to order two PC Engines AP
 U 4d4 boards from the awesome Pascal in Switzerland. These are cheap-ish l
 ittle fan-less single board computers with a 1 GHz AMD GX-412TC 4 core CPU
  (64-bit\, of course)\, 4GB RAM\, 4x Gbit Ethernet ports\, and plenty of o
 ther connectors and options. I put in a PCIe SSD card.\nI first talked to 
 the board's BIOS via a serial cable (was already up-to-date\, good)\, and 
 installed Debian 10 on it (with some minor hackery) from a USB stick.\n\nA
 nd behold\, my NBN HFC connection is now stable\, and faster.\n\nMaybe you
  would like to do something similar\, or maybe you just want to pick up a 
 few of the things that I've done - you can do any of this with a regular L
 inux box as well:\n - A few of the ports are configured as a switch\, usin
 g bridged network interfaces.\n - One port talks to the NBN HFC modem with
  PPPoE connection and a VLAN\, insisting it's actually the original ISP-pr
 ovided device.\n - IPv4/IPv6 native dual stack\, each with subnets (I just
  have those\, from when I ran a company from home)\n - Outbound rate-limit
 ing on the HFC connection to keep the stupid NBN happy.\n - Appropriate ke
 rnel tuning via sysctl - seemingly quite necessary for dealing with funny 
 traffic!\n - A hand-crafted effective firewall\, providing safety but also
  (when desired) insights in what fun tries to scan and gain access\, how a
 nd from where.\n - Configuring Unbound DNS to get rid of most ads on the L
 AN.\n - Surviving a reasonably-sized DDoS or other attack without flinchin
 g too much.\n - Using dynamic geo-blocking\, again with options to gain in
 sight.\n - WireGuard VPN end-point\, both for my own devices and for geo-t
 unneling (using policy routing) (* see below for a WireGuard love story)\n
  - Optional Suricata intrusion detection/prevention.\n - Being invisible f
 or scans\, if so desired.\nExtra options are adding mobile data backup wit
 h an on-board SIM card (may do)\, and wifi (might do using my 2nd board).\
 n\nIn this talk I will show what it all looks like on the outside and insi
 de\, and go over the configuration - understandable for small league nerds
 .\nSo you can do this yourself\, or just learn more about how the various 
 bits work.\n(Some entertaining stuff-ups and anecdotes are also included.)
 \n\n* A WireGuard love story\n\nWhat if there was a VPN that only requires
  a few thousand lines of code\, and lives inside the kernel?\nHorays! Than
 ks to Jason Donenfeld\, WireGuard is now available in recent Linux kernels
 \, and otherwise easy to add.\nBut how to set it all up? The documentation
  is kinda all there\, but mostly if you already know your stuff.\nTutorial
 s abound\, but some things have changed since. Aargh.\n\nSo now that the d
 ust has settled\, let's look at this from the non-whizz perspective.\nHow 
 to peer\, or set up a server with clients\, or a network tunnel with polic
 y routing.\nI'm not the expert\, but I've made it work and I can explain w
 hat I did.

  mess right now\, and doesn't look like sorting out any time soon.  The po
 st-WW-II / post-Cold War-I period of prosperity seems to have come to an e
 nd\, and the unfortunately predictable result is geo-political turmoil\, a
 nd the rising popularity of "strong" and "charismatic" leaders\, not disim
 ilarly to 100 years ago in Europe.  But in those 100 years\, technology ha
 s come a long way\, such that oppression by malevolent governments has bec
 ome much easier to achieve\, and much harder to escape\, if we rely on off
 -the-shelf solutions.    In short\, the Digital Summer may be drawing to a
  close\, and a Digital Winter looks likely to blow in to many countries.\n
  \nBut its not all doom and gloom:  The open-source community offers hope\
 , through its ability to create solutions that are decentralised and self-
 sufficient.  The Digital Summer is still with us\, and so we have time to 
 create effective solutions. We need systems that exhibit "Digital Sovereig
 nty".  By this\, we mean systems that cannot be subjugated\, subverted or 
 supplanted by hostile third-party actors\, such as state-level actors.  In
  short\, we need systems that will let people keep on communicating when t
 he proverbial hits the oscillatory.\n\nIn this talk I will explain more of
  these ideas of Digital Sovereignty\, the Digital Winter\, and how we can 
 work to shorten (or potentially avoid it) and how I am working to create a
  digitally sovereign smart-phone\, as an example of a Digitally Sovereign 
 device.

DESCRIPTION:Speaker: Aaron Boxer\nAI-powered video analytics is one of the
  most challenging applications of\nAI to edge devices\, given the edge's p
 ower\, compute\, and memory limitations.\nThis area is currently dominated
  by NVidia Deep Stream\, which suffers from:\n\n1. vendor-lock-in from CUD
 A language and NVidia hardware\n\n2. lack of transparency into low level t
 ensor operations and algorithms due to\nclosed source drivers and librarie
 s.\n\nCan we give freedom of choice back to AI multimedia developers ?\n\n
 Can we build a pure open source stack\, running from application to ML fra
 mework\ndown to GPU driver\, which allows complete transparency into the M
 L inference\nworkflow ?\n\nThe new Panfrost open source driver for Mali GP
 Us is solving this problem\non the edge by enabling a fast and efficient m
 achine learning stack\nrunning pure open source. Combining this with Tenso
 rFlow Lite and GStreamer\,\nwe get a powerful open source AI stack for vid
 eo analytics. And because\nthe stack is open from top to bottom\, we get v
 isibility into the complete\ninference process\, allowing us to better und
 erstand and explain how an \nanalytic model makes its predictions.\n\nThe 
 ability to explain how a model infers it's results (explainability) is an\
 nincreasingly desirable ML feature\, particularly in applications that hav
 e an impact\non privacy\, such as video facial recognition. Explainability
  allows us to build\nethical and trustworthy ML systems known to be free f
 rom bias. \nClosed source blobs and libraries interfere with explainabilit
 y by hiding\ncrucial computations from view. \n\nIn this talk\, we will wa
 lk through the process of building an AI-driven multimedia\npipeline on to
 p of a completely open source inference stack:\nopen source GPU driver\, m
 achine learning framework and machine learning models.\nWe will share what
  we have learned about optimizing these models to run fast\non resource-co
 nstrained hardware such as the Rockchip RK3399. And we will discuss\nhow t
 his completely open stack is a critical component of ethical and trustwort
 hy\nvideo analytics.\n\nHere is a link to the PDF of the slides: \n\nhttps

DESCRIPTION:Speaker: Christopher Biggs\nYou've hopefully heard of Linux\, 
 but have you heard of Tux's protege\, Zephyr?    Zephyr\, a Linux Foundati
 on project\, is a real time operating system targetted at computers too sm
 all to run Linux.   Zephyr aims to bring the Linux Effect to remote sensin
 g\, building automation\, industrial control\, and more.\n\nThere've been 
 a number of Zephyr talks at LCA in the past\, but I want to focus on the p
 racticalities of developing and testing an IoT solution running Zephyr\, w
 ith help from Linux.    Many of my projects involve zephyr devices that us
 e Bluetooth\, LoRa or 4G NbIoT and aren't directly reachable from the inte
 rnet for debugging and upgrades.   So when we're in the early stages of fi
 eld testing a Zephyr device\, we send a Linux box along as a Troop Leader 
 to look after the zephyr scouts.\n\nThis presentation will begin with the 
 practicalities of getting started with Zephyr---picking a board that is ea
 sy to use and getting you over the hump of beginning development.    The f
 irst few times I tried Zephyr\, encouraged by previous LCA speakers\, I ga
 ve up in frustration\, but eventually it "Clicked" and I want to share the
  tips and gotchas I've learned that will save you frustration.   Next\, I 
 will cover how I prepare an embedded linux system for remote cellular acce
 ss in the field (working around Telstra's frustrating use of multiple laye
 rs of NAT)\, and use this linux system to monitor and upgrade zephyr-based
  sensors during the test phase (SPOILERS: we use SaltStack\, ZeroTier and 
 MCUmgr to provision a Raspberry Pi to be a VPN gateway to the Zephyr devic
 es under development).\n\nAs an example\, we'll discuss a feral animal man
 agement solution that really does involve a Zephyr device (and sometimes i
 ts Linux troop leader) sitting in a tree\, observing and photographing ani
 mal behaviour.

  In 2019 we closed our doors\, to reshape our Federation Square building i
 n order to become more public-facing\, and to house a major new permanent 
 exhibition\, The Story of the Moving Image.\n\nAs you might imagine\, we h
 ave a lot of moving image to show\, and a lot of fascinating objects to te
 ll people about\, all of which can be overwhelming to some audiences. That
 's why we designed and built a system called The Lens. Every visitor to th
 e museum can pick up a Lens\, which they use to collect objects and media 
 to watch and explore in their own time. The Lens depends on a network of h
 undreds of Raspberry Pi devices to display media and interact with visitor
 s\, all running Python on Linux. All these devices need to be robust and m
 aintainable in order to survive the 10-year lifespan of the exhibition.\n\
 nIn this talk\, I'll give you a tour of the technology at ACMI\, including
  our Internet-of-Things fleet and management tools\, why Linux has been su
 ch a great choice for all of our devices\, and XOS\, the eXperience Operat
 ing System\, which provides content and configuration to the devices.

 about creating the physical form\, culminating in a device that even owner

 ve virtual shared space\, without a fixed purpose. It's a similar idea to 
 Second Life or to a lesser extent\, VR Chat. Vircadia is a fork of the now
  dead High Fidelity in its original incarnation. A simple way of looking a
 t it the 3D equivalent of Apache.\n\nWhat it does is providing a 3D enviro
 nment (with optional VR support) where to socialize\, script\, make games\
 , hold meetings\, or do most anything that could be done in a 3D setting. 
 It was made to be flexible and can serve many purposes.\n\nThis talk is ma
 de in response to the question "How can open source play a role in creatin
 g\, helping and adapting to this ongoing change? What new developments in 
 software and coding can we look forward to in 2021 and beyond?" made in th
 e call for submissions by Linux Conf AU\, and we think we have a good answ
 er.\n\nThe talk will be mostly a high level overview -- who we are\, where
  this all came from\, what is it good for and how we think it can be of gr
 eat help in current times\, as well as what are our plans for the future.

DESCRIPTION:Speaker: Leigh Brenecki\nIn the late 1970s\, industrial design
 er Dieter Rams wrote his "ten principles of good design"\, a set of aphori
 sms outlining how he saw his work. Rams and his ten principles have been h
 ugely influential on design to this day\, and that influence extends far b
 eyond Rams' realm of shelving systems\, wristwatches and FM radios—Apple
  chief designer Jony Ive cites him as an influence\, and articles applying
  the principles to web or UI design are a dime a dozen.\n\nBut we as devel
 opers are designers too\, whether we like it or not\, and not just on thos
 e occasions where we build something that faces an "end user". Our fellow 
 developers are also our users\, and the APIs and the developer tools that 
 we build are products that are designed\, intentionally or otherwise.\n\nI
 n this talk\, we'll use Rams' ten principles to explore good design of API
 s and developer tools\, and the things we should keep in our minds to buil
 d APIs and developer tools that are designed for our peers to use.

DESCRIPTION:Speaker: Derek Miller\nVeracruz is a privacy-preserving comput
 e infrastructure.  \nThe infrastructure allows secret data to be fed into 
 secret programs\, which are offloaded to third parties who host the comput
 ation\, and produce secret results.\n\nIn this setting\, everybody is mutu
 ally distrusting and has individual concerns:\n- The data and program owne
 rs want to retain their secrets\,\n- The host does not want their machine 
 to be damaged by programs they cannot audit or monitor\n\nVeracruz uses se
 cure enclaves as the venue for performing these computations. Trust in the
  enclave is established via remote attestation\, which establishes a trust
 ed public key specific to the enclave.\nSecret inputs (program\, data) are
  provisioned into the enclave using the trusted public key and TLS.\nResul
 ts are retrieved by an appointed agent.\n\nThe identities of all participa
 nts and their roles are compiled in a mutually agreed upon global policy f
 ile. The participants identities are established using TLS client certific
 ates embedded in the policy.\n\nPrograms are provided to the system in Web
  Assembly\, which allows the enclave software to enforce sandboxing of the
  provided program.\n\nVeracruz has implemented interfaces for Arm TrustZon
 e (running on QEMU)\, Intel's SGX\, and Amazon Nitro Enclaves. The specifi
 c details of each platform are abstracted from the parties in the computat
 ion.\n\nMost of the project is implemented in Rust to take advantage of it
 s improved memory safety as compared to other mainstream systems programmi
 ng languages.

 becoming available in new / upcoming ARM64 CPUs\, two new hardware extensi
 ons\, namely - LVA (Large Virtual Addressing)\nand LPA (Large Physical Add

  from Linux kernel version 5.4\, the 52-bit (Large) Virtual Address (VA) a
 nd Physical Address (PA) support was introduced for the ARM64\nkernel. Alt
 hough the kernel documentation describes these features (see [1] for more 
 details) and how they impact the new kernels running on older CPUs (which 
 don't support 52-bit VA extension in hardware) and the newer CPUs (which s
 upport 52-bit VA extension in hardware)\, it is still at-times complex for
  a normal user to understand the same and understand how one can "opt-in" 
 for receiving VAs from a 52-bit space.\n\nIn this talk\, I explain how:\nA
 . the kernel memory layout gets "flipped" for ARM64 after the support for 
 these features were added\,\nB. user-space applications\, especially the o
 nes which provide debugging support (e.g. kexec-tools\, makedumpfile and c
 rash-utility) get impacted because of the same\, and\nC. how user-space ap
 plications can "opt-in" to receiving VAs from a 52-bit space by specifying
  an mmap hint parameter that is larger than 48-bit.\n\n[1]. https://git.ke

DESCRIPTION:Speaker: Kathy Reid\nIt's estimated that by 2023\, there will 
 be 8 billion voice assistants in the world. We find them on our mobile dev
 ices. We find them in our cars. We find them embodied into hardware device
 s\, situated on in our living rooms\, our kitchens\, our bedrooms. Voice u
 ser interfaces - using natural spoken language to issue commands to a comp
 uting system - have been around for decades\, both in reality\, and in our
  imagination. Advances in machine learning and in embedded hardware mean t
 hat voice interfaces are experiencing a renaissance - just ask Siri\, or A
 lexa\, or OK Google. \n\nAt the same time\, traditional mainstays of open 
 source speech recognition and voice synthesis are in decline. For example\
 , the CMU Sphinx team has moved on to a commercial project. Common Voice a
 nd DeepSpeech from Mozilla are no longer being actively supported\, and th
 eir future (at the time of writing) is unclear. The open source voice assi
 stant community - Mycroft\, Julius\, Sepia\, OVAL - is fragmented\, and st
 ruggling to gain traction due to the power of content creators  - such as 
 Spotify - to dictate which channels their content can be accessed through.
  This reinforces the power and the dominance of proprietary players. \n\nT
 hose same proprietary players are driven by commercial considerations to o
 perate in markets that yield a profit - mostly white\, Western markets. Wi
 thout open source options\, much of the Global South will be under-served 
 by voice technology and its benefits - the ability to overcome poor litera
 cy\, gain instant access to information without a computer in your own lan
 guage - and so on. \n\nIf we're going to use voice technology to provide b
 enefits to some groups of people in the world\, and in doing so\, that rei
 nforces digital divides around inclusion\, equity and access\, then should
 n't voice technology be a public good?\n\nThere are several things we can 
 do to intervene in this state of affairs\, including\; \n\n- gaining more 
 widespread support and adoption of open source voice assistants\, which ai
 ds the case for content providers to support them\;\n- investing in voice 
 for low resource languages through measures such as corpora creation\, and
  tools for training low resource languages\; \n- ensuring that we know the
  value our voice data has for proprietary providers\, and choosing judicio
 usly when we share it\;\n- and allowing more services that have benefit to
  marginalised groups to deliver their services through voice user interfac
 es.\n\nBut there are significant barriers to achieving voice that is more 
 accessible to all\, including\; \n\n- the vast amounts of data required fo
 r training\;\n- the high barriers to entry of deep learning and machine le
 arning infrastructure\; \n- and differences in languages and accents \n\nT
 his talk will provide an overview of the landscape\, and identify where\, 
 and how\, we can best intervene to ensure everyone has a voice.

DESCRIPTION:Speaker: Joel Sing\nFollowing the publication of RFC 8446 in A
 ugust 2018\, the LibreSSL project wanted to add support for TLSv1.3. Howev
 er\, rather than shoehorning it into the existing code used by the TLSv1.2
  stack\, it was decided that the slower approach of developing a new TLS s
 tack from scratch would be preferable. Over the course of a year or so\, t
 hree people worked for approximately six weeks to produce a TLS stack cons
 isting of just under 7\,000 lines of C code.\n\nThis talk will look at the
  design decisions made and approaches taken while implementing a TLS stack
  from scratch. We'll discuss the challenges of fitting new code into an ex
 isting long standing API\, along with various problems encountered due to 
 assumptions made in existing open source software\, particularly failure m
 odes triggered by changes in API behaviour. Interoperability will be cover

DESCRIPTION:Speaker: Rafael Wysocki\nSuspend-to-idle is a system-wide susp
 end variant which in principle does not rely on platform support. The susp
 end-to-idle control flow does not take non-boot CPUs offline and expects a
 ll CPUs to enter idle states through the idle loop\, like in the working s
 tate of the system. However\, it assumes that the scheduler tick will be s
 topped on all CPUs and the timekeeping will be suspended\, which is a sour
 ce of significant complications. It also expects system wakeup devices sel
 ected by user space to be functional and it needs to prevent all of the ot
 her interrupt sources from waking up the system. In some cases one interru
 pt source can signal both wakeup and non-wakeup events\, so it is necessar
 y to distinguish the former from the latter. All of that together causes t
 he suspend-to-idle support code in the Linux kernel to be quite complex\, 
 especially on systems where ACPI is used\, and that code has changed for m
 ultiple times in response to additional pieces of information on what is n
 eeded coming mostly from the users in the form of problem reports. I will 
 describe the evolution of that code since its inception in 2013 and explai
 n the reasons for making the changes in it.

DESCRIPTION:Speaker: Josh Bassett\nHardware description languages\, like V
 erilog and VHDL\, have been used since the early 1980s to describe all typ

 oprocessors.\n\nWhile these languages are still widely considered to be in
 dustry-standard\, their tooling and ergonomics have fallen far behind mode
 rn software development best-practices. \n\nChisel is an open-source digit
 al design tool that leverages the Scala programming language\, providing d
 esigners with the power of a modern programming language to describe compl
 ex digital circuits. Importantly\, it also enables the use of many modern 
 software engineering practices (e.g unit testing\, static analysis\, CI\, 
 etc.).\n\nChisel is not a toy — it was most notably used by the Chips Al
 liance (Linux Foundation) to implement the open-source Rocket Chip RISC-V 
 processor core (https://github.com/chipsalliance/rocket-chip). It was also
  used by Google to develop the edge tensor processing unit ASIC (https://c
 loud.google.com/edge-tpu).\n\nThis talk aims to give an introduction to Ch
 isel\, and showcase how it can be used to create digital designs that are

DESCRIPTION:Speaker: Tim Serong\nThe Ceph project switched from installing
  regular software packages\, to deployment as application containers (Podm
 an/Docker/Kubernetes) in the most recent release.  Suddenly\, we have stor
 age clusters where the admin isn't dealing with a bunch of normal daemons 
 anymore\; instead there's a whole lot of containers running\, and if you'r
 e used to the old way of doing things\, the container mode can be inscruta
 ble\, and difficult to debug when things go wrong.\n\nThis isn't just a st
 ory for Ceph people - this is a story of unexpected failures\, of learning
  where to look when things break\, of trying to fix those broken things\, 
 and then discovering someone's hidden half your trusty old tools\, and the
  other half don't work properly anymore.\n\nCeph users will come away from
  this talk with a good understanding of how everything is deployed now\, a
 nd why.  Beyond that though\, I hope to ensure that anyone who's gone from
  dealing with packaged software to the container world never finds themsel
 ves like I did\, late one night\, staring at a terminal into which they've
  just typed the words "containers are hideously undebuggable black boxes a
 nd we never should have invented them".

DESCRIPTION:Speaker: Lana Brindley (she/her)\nOne thing the pandemic has f
 orced many of us to do is to take a step back. To just stop for a moment a
 nd think about where we are. And while you are taking stock of your person
 al life\, let me talk you through taking stock of your professional life\,
  or at least the bits of it you have managed to document. In the hustle of
  the beforetimes\, documentation was often a forgotten or sidelined thing 
 that you could do roughly now\, fix later\, or just never quite get around
  to. Take a deep breath\, look around your home office\, give the dog a pa
 t\, and let's work out what you have\, what you need\, and how you can ope
 n a can of Marie Kondo on all of it.

DESCRIPTION:Speaker: Neil McGovern\nIn August 2019\, GNOME was notified th
 at it was being sued in the state of California over a broad patent which 
 allegedly covered Shotwell\, a photo management application. The plaintiff
 ? A prolific filer of patent suits\, and a patent assertion entity. This w
 as the first time that a FOSS project has been sued for patent infringemen
 t.\n\nThis talk is the story from the Executive Director of the GNOME Foun
 dation\, on how he responded and the strategies taken to not only defeat t
 he suit\, but to secure a ground-breaking agreement which means that this 
 particular PAE will never be able to sue any FOSS project ever again.

 ing Google's main backbone to largely fall off the Internet. This is the s
 tory of how we used that incident as a learning opportunity\, how a lack o
 f buy-in hindered further improvements\, and how an existing toolkit of py
 thon libraries allowed testing and validation tools to be quickly built\, 
 preventing any chance of a recurrence.

 han getting a new gizmo and plugging it in only to discover it doesn’t w
 ork? We really didn’t want you to feel that way\, so we tested component
 s individually and again once each completed badge was assembled.\n\nLearn
  how we went about testing hundreds of badges in a time-effective manner\,
  and hear a tale of failures found and quirks uncovered\, and what we did 
 to recover.\n\nWe’ll also give a wrapup for OHMC2021\, the future for Sw
 agbadge\, our vision for Dagbadge and what we have in mind for the wider c
 ommunity.
