description: To draw the right conclusions based on environmental indicators can be a challenging task due to the consideration of a broad variety of environmental impacts that show diverging results. Many LCA practitioners seek help in interpreting diverging results in different impact categories by applying single score LCIA methods. But the ISO standards do not support weighting for publishing comparative LCA. Nevertheless, the increasing need for unequivocal results lead to the development of single score impact assessment method. This DF focuses on the present state of normalization and weighting in LCA. The statements in ISO 14040 are taken as one of the baselines, e.g. concerning internal and external normalization and hints on interpretation. The ongoing developments for the technical specification on this theme (ISO/TS 14074) are covered. Approaches broadening this view in ISO will be presented as well. An overview on present schemes such as the ILCD recommendations for LCIA and further developments within the EU Product Environmental Footprint (PEF) initiative will be provided. Another key question will be: How useful is the concept of the carrying capacity or the planetary boundaries for aggregating indicator scores? A discussion of different weighting methods should shed more light on the uncertainties and differences of various approaches (e.g. transparency, completeness, applicability). The forum should launch further discussion about these issues to initiate also a revision of standards like ISO 14040/44/74 to better reflect the current state of the art. In summary, the DF aims at a critical discussion and review of currently available methods for normalization and weighting to promote a better understanding of the complex topic and controversial debate in the scientific community. How ISO standards on weighting, normalization and grouping can be implemented in the future are identified. Research needs are formulated to foster progress in this field of LCA application. This forum aims to provide a fertile ground for discussion between LCA researchers, practitioners and other people interested in the interpretation and development of normalization and weighting methods.

description: Materials from renewable feedstocks may cause significant environmental impacts due to land use and land use change related to feedstock sourcing. Whilst these impacts are clearly spatially-dependent, spatially-resolved impact assessment is often hampered by lack of data, and in some cases, methods or models. In addition, the location and impacts of production are likely to change in the future, e.g. due to the consequences of climate change and due to sourcing trends in a growing economy and considering geopolitical conditions. This discussion forum will focus on 1) Methods that can be used to track the current locations of crop production systems in complex supply chains to support spatially resolved impact assessment and 2) Methods and tools to predict future locations of crops in the context of megatrends such as climate change and increasing demand for agricultural raw materials. 3) Advances of methods for spatially resolved consideration of environmental impacts of land use change will also be covered in this LCA forum.

description: Roman Architecture (HSAR 252) Professor Kleiner discusses the development of Third Style Roman wall painting in late first century B.C. villas belonging to the imperial family and other elite patrons. Third Style painting, as Professor Kleiner demonstrates, is characterized by departure from the perspectival vistas and panoramas of the Second Style toward an attenuation of architectural elements and a respect for the inherent flatness of the wall. The Third Style remains popular until the middle of the first century A.D., when it is replaced by the Fourth Style of Roman painting; both styles coexist in the Domus Aurea, the luxurious pleasure palace of the emperor Nero in downtown Rome. Professor Kleiner characterizes the Fourth Style of Roman wall painting as a compendium of previous styles, with imitation marble veneer, framed mythological panels, and the introduction of fragments of architecture situated in an illogical space. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner discusses special subjects in Roman wall painting that do not fall within the four architectural styles but were nonetheless inserted into their wall schemes: mythological painting, landscape, genre, still life, history painting, and painted portraiture. The lecture begins with an in-depth examination of the unique Dionysiac Mysteries painting in Pompeii in which young brides prepare for and enter into a mystical marriage with the god Dionysus and simultaneous initiation into his cult. Professor Kleiner then presents a painted frieze from Rome that depicts the wanderings of Odysseus against a continuous landscape framed by Second Style columns. She subsequently analyzes Roman still life, remarkable in its similarity to modern still life painting; a scene of daily life in Pompeii; and a painting depicting a specific historical event--a riot in the Pompeii Amphitheater that caused the arena to be shut down for ten years. The lecture ends with a discussion of painted portraiture on Pompeian walls, including likenesses of two different women holding a similar stylus and wax tablet. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner discusses the transformation of Rome by its first emperor, Augustus, who claimed to have found Rome a city of brick and left it a city of marble. The conversion was made possible by the exploitation of new marble quarries at Luna (modern Carrara) on the northwest coast of Italy. The lecture surveys the end of the Roman Republic and the inauguration of the Principate and analyzes the Forum of Julius Caesar and the Forum of Augustus. Professor Kleiner shines a spotlight on Caesar's attempt to link himself to his divine ancestress Venus Genetrix and on Augustus' appropriations of Greek caryatids and other decorative motifs that associate his era with the Golden Age of Periclean Athens. Finally, she analyzes the Ara Pacis Augustae, a monument commissioned upon Augustus' return to Rome after achieving diplomatic victories in Spain and Gaul, and serving as the Luna marble embodiment of the emperor's new hegemonic empire. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner explores sepulchral architecture in Rome commissioned by the emperor, aristocrats, successful professionals, and former slaves during the age of Augustus. Unlike most civic and residential buildings, tombs serve no practical purpose other than to commemorate the deceased and consequently assume a wide variety of personalized and remarkable forms. The lecture begins with the round Mausoleum of Augustus, based on Etruscan precedents and intended to house the remains of Augustus and the new Julio-Claudian dynasty. Professor Kleiner also highlights two of Rome's most unusual funerary structures: the pyramidal Tomb of Gaius Cestius, an aristocrat related to Marcus Agrippa, and the trapezoidal Tomb of Marcus Vergilius Eurysaces, probably a former slave who made his fortune overseeing the baking and public distribution of bread for the Roman army. Professor Kleiner concludes the lecture with a brief discussion of tombs for those with more modest means, including extensive subterranean columbaria. She also turns briefly to the domed thermal baths at Baia, part of an ancient spa and a sign of where concrete construction would take the future of Roman architecture. 00:00 - Chapter 1.

She first presents Tiberius' magnificent Villa Jovis on the Island of Capri and an underground basilica in Rome used by members of a secret Neo-Pythagorean cult. She then turns to the eccentric architecture of Claudius, a return to masonry building techniques and a unique combination of finished and unfinished, or rusticated, elements. Finally, Professor Kleiner highlights the luxurious architecture of the infamous Nero, especially his Domus Aurea or Golden House and its octagonal room, one of the most important rooms in the history of Roman architecture. The construction of the Domus Aurea accelerates the shift in Roman building practice toward a dematerialized architecture that fully utilizes recent innovations in concrete technology and emphasizes interior space over solid form. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner features the tumultuous year of 68-69 when Rome had four competing emperors. Vespasian emerged the victor, founded the Flavian dynasty, and was succeeded by his sons, Titus and Domitian. The Flavians were especially adept at using architecture to shape public policy. Professor Kleiner demonstrates that Vespasian linked himself with the divine Claudius by completing the Claudianum and distanced himself from Nero by razing the Domus Aurea to the ground and filling in the palace's artificial lake. In that location, Vespasian built the Flavian Amphitheater, nicknamed the Colosseum, thereby returning to the people land earlier stolen by Nero. Professor Kleiner discusses the technical and aesthetic features of the Colosseum at length, and surveys Vespasian's Forum Pacis and Titus' Temple to Divine Vespasian. The lecture concludes with the Baths of Titus, Rome's first preserved example of the so-called "imperial bath type" because of its grand scale, axiality, and symmetry. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner investigates the major architectural commissions of the emperor Domitian, the last Flavian emperor. She begins with the Arch of Titus, erected after Titus' death by his brother Domitian on land previously occupied by Nero's Domus Transitoria. The Arch celebrated Titus' greatest accomplishment--the Flavian victory in the Jewish Wars--and may have served as Titus' tomb. Professor Kleiner also discusses the Stadium of Domitian, the shape of which is preserved in Rome's Piazza Navona. Her major focus is the vast Imperial Palace on the Palatine Hill designed by the architect Rabirius and featuring Domitian as dominus et deus (lord and god). Constructed from brick-faced concrete and revetted with multicolored imported marbles, this structure was divided into public and private wings, and was so magnificent that it served as the urban residence of all subsequent Roman emperors. The lecture concludes with the so-called Forum Transitorium, a narrow forum begun by Domitian and finished by his successor Nerva, which features a temple to Domitian's patron goddess Minerva and a series of decorative columnar bays that create a lively in-and-out undulation that heralds the beginning of a "baroque" phase in Roman architecture. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner analyzes the major public architectural commissions of the emperor Trajan in Rome. Distinguished by their remarkably ambitious scale, these buildings mimic Trajan's expansion of the Roman Empire to its furthest reaches. Professor Kleiner begins with Trajan's restoration of the Forum of Julius Caesar and proceeds to the Baths of Trajan. Situated on the Oppian and Esquiline Hills, these Trajanic baths follow the basic model of the earlier imperial Baths of Titus but increase the size of the complex several times. Most of the lecture focuses on the famous Forum and Markets of Trajan, built on land that the engineer and architect Apollodorus of Damascus created by cutting away part of the Quirinal Hill. The Forum of Trajan consists of a large open rectangular area, a basilica, Greek and Latin libraries, and a temple dedicated to Trajan after his death. Between the libraries stands the celebrated Column of Trajan with a spiral frieze commemorating the emperor's military victories in Dacia (modern Romania) and reaching a height of 125 feet. The brick-faced concrete Markets of Trajan climb up the hill and form a dramatic contrast to the marble forum. The lecture concludes with a brief discussion of the Arch of Trajan at Benevento, which depicts scenes of the emperor's greatest accomplishments and the first representations of his successor, Hadrian. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner features the architecture built in and around Rome during the reign of Hadrian. The lecture begins with the Temple of Venus and Roma, a Greek-style temple constructed near the Colosseum in Rome, which may have been designed by Hadrian himself. Professor Kleiner then turns to the Pantheon, a temple dedicated to all the gods that combines the marble porch and pediment of a traditional Greco-Roman temple with a vast concrete cylindrical drum, hemispherical dome, and central oculus. The porch serves to conceal the circular shape from view, but upon entering the structure the visitor is impressed by the massive interior space and theatrical play of light. The Pantheon represents the culmination of the Roman quest towards an architecture that shapes and dramatizes interior space. Professor Kleiner next discusses the Villa of Hadrian at Tivoli, a sprawling complex in which the emperor re-created buildings and works of art he observed during his empire-wide travels. The lecture concludes with a brief overview of the Mausoleum of Hadrian (the Castel Sant'Angelo), a round tomb that refers back to the Mausoleum of Augustus and served as the last resting place for Hadrian and the succeeding Antonine dynasty. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner focuses on Ostia, the port of Rome, characterized by its multi-storied residential buildings and its widespread use of brick-faced concrete. She begins with the city's public face--the Forum, Capitolium, Theater, and Piazzale delle Corporazioni. The Piazzale, set behind the Theater, was the location of various shipping companies with black-and-white mosaics advertising their business. Professor Kleiner examines the Baths of Neptune and the Insula of Diana, a brick apartment building with four floors that housed a number of Ostia's working families. The Insula of Diana and other similar structures, including warehouses like the Horrea Epagathiana, demonstrate a fundamental feature of second-century Ostia: the appreciation of the aesthetic qualities of brick facing. Since the time of Nero, brick was customarily covered with stucco and paint, but these Ostian buildings are faced with exposed brick, the color, texture, and design of which make it attractive in its own right. The lecture ends with a survey of several single family dwellings in Ostia, including the fourth-century House of Cupid and Psyche, notable for the pastel-colored marble revetment on its walls and floors and for a charming statue of the legendary lovers. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner discusses the increasing size of Roman architecture in the second and third centuries A.D. as an example of a "bigger is better" philosophy. She begins with an overview of tomb architecture, a genre that, in Rome as in Ostia, embraced the aesthetic of exposed brick as a facing for the exteriors of buildings. Interiors of second-century tombs, Professor Kleiner reveals, encompass two primary groups -- those that are decorated with painted stucco and those embellished primarily with architectural elements. After a discussion of the Temple of the Divine Antoninus Pius and Faustina and its post-antique afterlife as the Church of S. Lorenzo in Miranda, Professor Kleiner introduces the Severan dynasty as it ushers in the third century. She focuses first on the Arch of Septimius Severus in the Roman Forum, the earliest surviving triple-bayed arch in Rome. She next presents the so-called Septizodium, a lively baroque-style façade for Domitian's Palace on the Palatine Hill. The lecture concludes with the colossal Baths of Caracalla, which awed the public by their size and by a decorative program that assimilated the emperor Caracalla to the hero Hercules. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner discusses two Roman cities in North Africa: Timgad and Leptis Magna. Timgad was created as an entirely new colony for Roman army veterans by Trajan in A.D. 100, and designed all at once as an ideal castrum plan. Leptis Magna, conversely, grew more gradually from its Carthaginian roots, experiencing significant Roman development under Augustus and Hadrian. Septimius Severus, the first Roman emperor from North Africa, was born at Leptis and his hometown was renovated in connection with his historic visit to the city. This large-scale program of architectural expansion features the Severan Forum and Basilica and the nearby Arch of Septimius Severus, a tetrapylon or four-sided arch located at the crossing of two major streets. The lecture culminates with the unique Hunting Baths, a late second or early third-century structure built for a group of entrepreneurs who supplied exotic animals to Rome's amphitheaters. Its intimate vaulted spaces are revealed on the outside of the building and silhouetted picturesquely against the sea, suggesting that the bath's owners knew how to innovate through concrete architecture and how to enjoy life. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner features the baroque phenomenon in Roman architecture, in which the traditional vocabulary of architecture, consisting of columns and other conventional architectural elements, is manipulated to enliven building façades and inject them with dynamic motion. This baroque trend is often conspicuously ornamental and began to be deployed on the walls of forums and tombs in Italy already in the late first century A.D. But baroque architecture in Roman antiquity was foremost in the Greek East where high-quality marble and expert marble carvers made it the architectural mode of choice. At Petra in Jordan, tomb chambers were cut into cliffs and elaborate façades carved out of the living rock. The cities of Miletus and Ephesus in Asia Minor were adorned with gates and fountains and libraries and stage buildings that consisted of multi-storied columnar screens. The lecture culminates with the Sanctuary of Jupiter Heliopolitanus, a massive temple complex at Baalbek in Lebanon, with Temples of Jupiter and Bacchus in enormous scale and with extreme embellishment, and the Temple of Venus with an undulating lintel that foreshadows the curvilinear flourishes of Francesco Borromini's S. Carlo alle Quattro Fontane in seventeenth-century Rome. 00:00 - Chapter 1. Baroque Architecture in the Roman Empire 11:51 - Chapter 2. Exploring Baroque Elements in Italy 23:41 - Chapter 3.

description: Roman Architecture (HSAR 252) Professor Kleiner discusses the rebirth of Athens under the Romans especially during the reigns of the two philhellenic emperors, Augustus and Hadrian. While some have dismissed the architecture of Roman Athens as derivative of its Classical and Hellenistic Greek past, Professor Kleiner demonstrates that the high quality of Greek marble and Greek stone carvers made these buildings consequential. In addition some structures provide evidence for the frequent and creative exchange of architectural ideas and motifs between Greece and Rome in Roman times. After a brief introduction to the history of the city of Athens, Professor Kleiner presents the monuments erected by Augustus and Agrippa on the Acropolis and in the Greek and Roman Agoras, for example the Odeion of Agrippa. Following with Hadrian's building program, she features an aqueduct and reservoir façade, the Library of Hadrian, and the vast Temple of Olympian Zeus, a project begun over six hundred years earlier. Professor Kleiner concludes the lecture with the Monument of Philopappos, a Trajanic tomb on the Mouseion Hill built for a man deprived of the kingship of Commagene by the Romans, but who made the best of the situation by becoming a suffect consul in Rome and then moving to Athens, where he died and was memorialized by his sister Balbilla. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Professor Kleiner explores the architecture of the western provinces of the Roman Empire, focusing on sites in what are now North Italy, France, Spain, and Croatia. Her major objective is to characterize "Romanization," the way in which the Romans provide amenities to their new colonies while, at the same time, transforming them into miniature versions of the city of Rome. Professor Kleiner discusses the urban design of two Augustan towns before proceeding to an investigation of a variety of such established Roman building types as theaters, temples, and aqueducts. The well-preserved Theater at Orange, the Maison Carrée at Nîmes, and the unparalleled aqueducts at Nîmes (the Pont-du-Gard) and Segovia are highlighted. The lecture concludes with an overview of imperial and private arches and tombs in the western provinces, among them the controversial three-bayed arch at Orange. The Trophy of Augustus at La Turbie serves as a touchstone for the Roman West, as it commemorates Augustus' subjugation of the Alpine tribes, clearing the way for Rome to create new cities with a distinctive Roman stamp. 00:00 - Chapter 1.

Rome Redux: The Tetrarchic Renaissance

uk: Архітектура, дизайн інтер'єру

description: Roman Architecture (HSAR 252) Professor Kleiner characterizes third-century Rome as an "architectural wasteland" due to the rapid change of emperors, continuous civil war, and a crumbling economy. There was no time to build and the only major architectural commission was a new defensive wall. The crisis came to an end with the rise of Diocletian, who created a new form of government called the Tetrarchy, or four-man rule, with two leaders in the East and two in the West. Diocletian and his colleagues instituted a major public and private building campaign in Rome and the provinces, which reflected the Empire's renewed stability. Professor Kleiner begins with Diocletian's commissions in Rome--a five-column monument dedicated to the tenth anniversary of the formation of the Tetrarchy, the restoration of the Curia or Senate House, and the monumental Baths of Diocletian. She then presents Diocletian's Palace at Split, designed as a military camp and including the emperor's octagonal mausoleum, followed by an overview of the palaces and villas of other tetrarchs in Greece and Sicily. Professor Kleiner concludes with the villa on the Via Appia in Rome belonging to Maxentius, son of a tetrarch, and the main rival of another tetrarch's son, Constantine the Great. 00:00 - Chapter 1.

Rome of Constantine and a New Rome

uk: Архітектура, дизайн інтер'єру

description: Roman Architecture (HSAR 252) Professor Kleiner presents the architecture of Constantine the Great, the last pagan and first Christian emperor of Rome, who founded Constantinople as the "New Rome" in A.D. 324. She notes that Constantine began with commissions that were tied to the pagan past (the Baths of Constantine in Rome) but built others (the Aula Palatina at Trier) that looked to the Christian future. Professor Kleiner makes an impassioned case that some of the finest and most innovative Roman buildings date to the Constantinian period. The "Temple of Minerva Medica," a garden pavilion, for example, is decagonal in shape and the colossal Basilica Nova was inventively modeled on the frigidaria of Roman imperial bath complexes. In addition, the Arch of Constantine, a triple-bayed structure commemorating Constantine's victory over Maxentius at the Battle of the Milvian Bridge, serves as a compendium of Constantine's accomplishments in the context of those of the "good emperors" of the second century A.D. In conclusion, Professor Kleiner asserts that the transfer of the Empire's capital from Rome to Constantinople diminished Rome's influence, at least temporarily, but not the impact of its architecture, which like the city of Rome itself, is eternal. 00:00 - Chapter 1.

description: Roman Architecture (HSAR 252) Kleiner presents the three options for the course's term paper, which fall into two main categories: a research paper or a project to design a Roman city. For the research paper, she suggests cities and monuments not covered or mentioned briefly in the lectures, which embody some of the themes and issues raised in the course. Such topics include, in the Eastern Empire, the Roman cities of Corinth and Gerasa (Jerash), the Library of Celsus at Ephesus, and the Temple of Bel and the tower tombs at Palmyra. In the West, possible subjects are the Villa of the Papyri at Herculaneum; funerary architecture in Pompeii; a Roman villa at Fishbourne; Roman baths at Bath; and the private houses at Vaison-la-Romaine. Students may also study a site or monument of their choice, provided that the topic is pre-approved by Professor Kleiner.

She describes the plan of the ideal domus italica and features two residences that conform to that layout. She then presents the so-called Hellenized domus that incorporates elements of Greek domestic architecture, especially the peristyle court with columns. The primary example is the famous House of the Faun with its tetrastyle atrium, double peristyles, and floor mosaic of the battle between Alexander the Great and Darius of Persia at Issus, a Roman copy of an original Greek painting.

The lecture begins with an introduction to the history of the city of Herculaneum and what befell some of its inhabitants when they tried to escape obliteration by Vesuvius. She features three houses in Herculaneum, two of which--the Houses of the Mosaic Atrium and the Stags--are among the best examples of a residential style popular in Campania between A.D. 62 and 79. Professor Kleiner then turns to the First or Masonry Style of Roman wall painting, which seeks to replicate the built architecture of Hellenistic kings and other elite patrons by using stucco and paint to imitate a real wall faced with marble. She follows with Second Style Roman wall painting, which uses only paint to open up the wall illusionistically onto vistas and prospects of sacred shrines, city scenes, and landscapes. The lecture concludes with a discussion of the Garden Room from the Villa of Livia at Primaporta, which epitomizes the Second Style by transforming the flat wall into a panoramic window. 00:00 - Chapter 1.

description: Presenting traceloop, a “time travel” tracing tool to trace system calls in cgroups using BPF and overwritable ring buffers. Many people use the “strace” tool to synchronously trace system calls using ptrace. Traceloop similarly traces system calls but asynchronously in the background, using BPF and tracing per cgroup. I’ll show how it can be integrated with systemd and with Kubernetes via [Inspektor Gadget](https://github.com/kinvolk/inspektor-gadget). Traceloop's traces are recorded in a fast, in-memory, overwritable ring buffer like a flight recorder. As opposed to “strace”, the tracing could be permanently enabled on systemd services or Kubernetes pods and inspected in case of a crash. This is like a always-on “strace in the past”. Traceloop uses BPF through the gobpf library. Several new features have been added in gobpf for the needs of traceloop: support for overwritable ring buffers and swapping buffers when the userspace utility dumps the buffer.

In this talk we will show you the benefits and drawbacks of different approaches and what solution we finally chose. Probably everybody who uses Kubernetes in a productive environment with multiple users possibly has looked at policies. Often the operators of the cluster(s) just trust the policies but in some cases it might be useful to control if the policies actually have taken action and often there are just to many Policies in the cluster setup to manually test them all (and obviously you don’t want to do this). Testing the effectiveness of the Network Policies can be done in different approaches. In this talk we will show you the benefits and drawbacks of different approaches and what solution we finally chose. Also we will show you some other tools and how they complement our solution. As a takeaway you will get an overview of different testing strategies for policies, as well as understanding challenges in testing policies in general and the Kubernetes ecosystem. We will get a feeling that it’s not always the best idea to just trust other plugins to implement the policies correctly. Our solution is open-sourced under

description: We will present Yomi, a new proposal for installing Linux using SaltStack. This installer is designed to be used in heterogeneous clusters, where you need a bit of intelligence during the installation and be integrated as one more step in the provisioning process. [Yomi] is a new kind of installer for the [open]SUSE family based on SaltStack and independent of AutoYaST. The goal of this project is to make the installation of Linux (currently openSUSE) when: * You have a cluster of heterogeneous nodes (different profiles of memory, storage, CPU and network configurations) * The installation needs to be unattended * The installer needs to make decisions based on local profiles and external data * The installation process needs to be integrated, as one step more, into a more complicated provisioning workflow. The dependencies of Yomi are minimal, as only Salt and a very few CLI tools are required, which make it ideal to be deployed a booted from PXE Boot.

description: Atomic Updates and user modified configuration files in /etc often lead to hard to resolve conflicts. In this talk, I want to show the most common and biggest problems and possible solutions. More and more Linux Distributors have a Distribution using atomic updates to update the system. They all have the problem of updating the files in /etc, as an admin could do changes after the update but before the reboot to activate the updates. But everybody come up with another solution which solves their usecase, but is not generic useable. Additional there is the "Factory Reset" of systemd, which no big distribution has really fully implemented today. A unique handling of /etc for atomic updates could also help to convince upstream developers to add support to their applications, while currently they hesitate to add distribution specific patches and support. During this talk, I will describe the different areas of problems and possible solutions. The goal is to provide a concept working for all Linux Distributors (like the FHS). My dream is, that no package installs anything in /etc, it should only contain changes made by the system administrator or configuration files managed by the system administrator. For some problems, it would be already enough today if Linux distributors would adjust the configuration of applications or use all features of them. Other requires minimal to intrusive changes to packages, and for the last kind complete new concepts are necessary.

description: Buck is an opensource build system. At Facebook, we’ve taught it to build container images that work with systemd. At Facebook we use an open-source build system called Buck. Buck is a build system designed to provide more strong guarantees of incremental builds, reproducibility, and dependency management. Open-source Buck can now be used to construct fully described and fully self-contained container images that work with systemd! I will show how we use this tool internally at Facebook and how it can be used externally (It’s open-source!) to build service containers for use by systemd. I will dive into the the details of how these builds are performed with systemd-nspawn, how we use the Buck system to define the systemd services and their dependencies, and how these images work at runtime.

description: The embedded world has dealt with image creation for decades. Why not use those decade of experience to reliably create image for the datacenter world ? Building an OS image in a reliable, reproducible, tracable and archivable way is a hard problem, but it is a problem that the embedded world has been working on for decades and where mature and easy to use tools exist Nowdays, the world of containers is rediscovering these problems and most tools do not provide the level of tracability and reliability needed to be able to properly track the content of an image in every detail and be confident that it is possible to report what changes are local and what licenses are used. Buildroot is one of the tools the embedded world provides to solve that problem. It is robust, mature, deadly simple to use and can really help getting back the control on container images.

description: How to run clusters for GPU computing based blockchain hashing diskless on cost effective commodity hardware. Running the nodes of a cluster diskless is quite common in HPC environments. The challenges to run diskless in the context of blockchain hashing for cryptocurrencies are different. There are constraints like to run sufficiently on hundreds of machines with commodity 1 Gbit/s network hardware or the modest RAM size of 4 Gigabyte. This talk will provide insights in the technical approaches that made it possible to run GPU-clusters for blockchain hashing diskless and provide an outlook to other potential GPU-based use cases beyond blockchain hashing. I will discuss like how some early userspace trickery and state of the art RAM compression is used. How to handle the modest given RAM size and how a neat toolset based on container-runtimes helps to easily build boot images and plug-in packages. And how to use plug-in packages as an elegant way for adding further software like proprietary GPU drivers to the computing nodes of the clusters.

description: The difficult task to checkpoint and restore a process is used in many container runtimes to implement container live migration. This talk will give details how CRIU is able to checkpoint and restore processes, how it is integrated in different container runtimes and which optimizations CRIU offers to decrease the downtime during container migration. In this talk I want to provide details how CRIU checkpoints and restores a process. Starting from ptrace() to pause the process, how parasite code is injected into the process to checkpoint the process from its own address space. How CRIU transforms itself to the restored process during restore. How SELinux and seccomp is restored. I also want to give an overview how CRIU uses userfaultfd for lazy migration and dirty page tracking for pre-copy migration. I want to end this talk with an overview about how CRIU is integrated in different container runtimes to implement container live migration.

Custom cgroup-bpf programs in systemd

uk: Комп'ютерні науки

description: The primary focus is to gather feedback from systemd community regarding ongoing and future work to introduce custom cgroup-bpf programs to systemd. The motivation is to give a user a capability to attach their own cgroup-bpf programs to systemd containers. This is a continuation of started at ASG2018 and followed by and . Currently systemd utilizes BPF macro-assembly which is poorly extendable and maintainable, so the 1st iteration would be introducing `libbpf` library to systemd. The first attempt was made and it raised valid questions about `libbpf` testability and dependencies it introduces. We’d like to address that. Another topic of focus may be implementation details, such as how to store libbpf programs: either as bytecode or as restricted C which compiles with the rest of systemd. For attendees with no context a brief intro to eBPF will be made including new initiatives which may be of use to systemd, e.g. “Compile once, run everywhere”. Since this is ongoing work the agenda may vary depending on activity in PRs.

description: BuildStream is used to build Freedesktop SDK for different deployment systems allowing applications based on it to be distributed at once to multiple systems. Flatpak, Snapd and Docker are similar. They are all used for deployment and applications use their own runtime. Each system has its own tools for development. Flatpak uses Flatpak Builder. Snapd uses Snapcraft. Docker development is based on `Dockerfile`s. Freedesktop SDK was developed to be the runtime of Flatpak. It used to be partly built with Flatpak Builder. It has since changed to be built with a deployment system agnostic tool: BuildStream. For this reason we can export the Freedesktop SDK to multiple formats. We will show how it is possible to build an application for the three systems at once.

eBPF support in the GNU Toolchain

This talk covers the ongoing effort about adding eBPF support to the GNU Toolchain. eBPF is a virtual machine running within the Linux kernel; initially intended for user-level packet capture and filtering, eBPF has since been generalized to also serve as a general-purpose infrastructure for non-networking purposes. Binutils support is already upstream. This includes a CGEN cpu description, assembler, disassembler and linker. By the time of the conference a simulator will be available as well, along with GDB support. A GCC backend will be submitted for inclusion upstream before September. The first part of the talk will be a brief general description of the project, its components, what motivated us to start working on it, and an update on the project's status at the time of the conference. Then we will discuss the particular challenges of supporting a target like eBPF: On one hand, the kernel virtual machine has some unique characteristics that have a definitive impact on the tooling, like the in-kernel validator and the specialized contexts in which eBPF programs run. We will show how the tools can help improving the eBPF programmer's experience. On the other hand, the exact shape of compiled eBPF code is still subject to change, and is in fact rapidly changing and evolving. Initially quite simple in terms of toolchain needs (single compilation units, no linking) this is changing as more kernel systems are being changed/written to be based on eBPF, and as the in-kernel validator is becoming more and more sophisticated. Along with bigger and more complex programs comes the need for more abstraction, hence modularity and code reuse. Kernel hackers are already discussing about bpf-to-bpf calls, run-time linking, and so on. This increased level of ambition and sophistication imposes additional requirements on the tools. Finally, interoperability with clang/llvm (the other available toolchain supporting eBPF) will be also discussed, in the more general context of ABI and conventions for compiled eBPF, which are still to be (well) defined and documented.

description: Currently everyone uses the same seccomp rules for running their containers. This tool allows us to generate seccomp rules based on what the container actually requires and allows us to lock down the container. We had a GSOC student this summer who instrumented podman to allow it to run containers and then genrate the seccomp rules for the container based on the syscalls that the container actually made. Once you have this newly generate seccomp file and are satisfied that you have thoroughly tested the container, you can run the container inproduction using the seccomp.json file. This talk will explain how the tool works and demonstrate it in action.

GNU poke is a new interactive editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them. Once a user has defined a structure for binary data (usually matching some file format) she can search, inspect, create, shuffle and modify abstract entities such as ELF relocations, MP3 tags, DWARF expressions, partition table entries, and so on, with primitives resembling simple editing of bits and bytes. The program comes with a library of already written descriptions (or "pickles" in poke parlance) for many binary formats. GNU poke is useful in many domains. It is very well suited to aid in the development of programs that operate on binary files, such as assemblers and linkers. This was in fact the primary inspiration that brought me to write it: easily injecting flaws into ELF files in order to reproduce toolchain bugs. Also, due to its flexibility, poke is also very useful for reverse engineering, where the real structure of the data being edited is discovered by experiment, interactively. It is also good for the fast development of prototypes for programs like linkers, compressors or filters, and it provides a convenient foundation to write other utilities such as diff and patch tools for binary files. This talk (unlike Gaul) is divided into four parts. First I will introduce the program and show what it does: from simple bits/bytes editing to user-defined structures. Then I will show some of the internals, and how poke is implemented. The third block will cover the way of using Poke to describe user data, which is to say the art of writing "pickles". The presentation ends with a status of the project, a call for hackers, and a hint at future works.

If we have a service which can do all of this, why not propose a new upstream release automatically as a change to the linux distro once the release is done? Wouldn't it be awesome if upstream developers could control and track in which version their software is in Fedora 30? Sounds interesting?

description: Most modern container image formats use tar-based linear archives to represent root filesystems, which results in many issues when using modern container images. In this talk, we will demonstrate a solution to this problem that we plan to propose for standardisation within the Open Container Initiative (code-named "OCIv2 images"). This talk is specific to the Open Container Initiative's image specification, but the same techniques could be applied to other systems (though we'd obviously recommend using OCI). In order to avoid the [numerous issues with tar archives](https://www.cyphar.com/blog/post/ociv2-images-i-tar) it is necessary to come up with a different format. In addition, layer representations result in needless wasted space for storage of files which are no longer relevant to running containers. Massive amounts of duplication are also rampant within OCI images because tar archives are completely opaque to OCI's content-addressable store. Luckily the problem of representing a container root filesystem for distribution is very similar to existing problems within backup systems, and we can take advantage of prior art such as [restic](https://restic.net/) to show us how we can get significant space-savings and possibly efficiency savings. However, we also must ensure that the runtime cost of using this new system is equivalent to existing container images. Container images are efficient at runtime because they map directly to how overlay filesystems represent change-sets as layers, but with some tricks it is possible for us to obtain most of the improvements we also gained in distribution with de-duplication. Our proposed solution to all of these problems will be laid out, with opportunities for feedback and discussion.

description: oomd is a userspace out-of-memory killer. This talk covers past, present, and future development along with possible plans for systemd integration. Running out of memory on a host is a particularly nasty scenario. In the Linux kernel, if memory is being overcommitted, it results in the kernel out-of-memory (OOM) killer kicking in. Perhaps surprisingly, the kernel does not often handle this well. oomd builds on top of recent kernel development to effectively implement OOM killing in userspace. This results in a faster, more predictable, and more accurate handling of OOM scenarios. oomd has gained a number of new features and interesting deployments in the last year. The most notable feature is a complete redesign of the control plane which enables arbitrary but "gotcha"-free configurations. In this talk, Daniel Xu will cover past, present, future, and path-not-taken development plans along with experiences gained from overseeing large deployments of oomd. Anita Zhang will close the talk with a discussion of why oomd would be a great addition to systemd.

description: Traditionally processes are identified globally via process identifiers (PIDs). Due to how pid allocation works the kernel is free to recycle PIDs once a process has been reaped. As such, PIDs do not allow another process to maintain a private, stable reference on a process. On systems under pressure it is thus possible that a PID is recycled without other (non-parent) processes being aware of it. This becomes rather problematic when (non-parent) processes are in charge of managing other processes as is the case for system managers or userspace implementations of OOM killers. Over the last months we have been working on solving these and other problems by introducing pidfds – process file descriptors. Among other nice properties, the allow callers to maintain a private, stable reference on a process. In this talk we will look at challenges we faced and the different approaches people pushed for. We will see what already has been implement and pushed upstream, look into various implementation details and outline what we have planned for the future.
