Practical information on how to Optimize Virtual Machines for High Performance by Boyan Krosnov, Chief Product Officer at StorPool Storage
Presentation delivered at OpenNebula TechDay Sofia on 25-th of February 2016
How do you operate over 1,200 deployments on a single BOSH Director? In the past many talks have had the Topic of Cloud Foundry at scale. But how about the underlying automation layer? BOSH has its own set of challenges and limits for running VMs and Deployments at scale. Learn which obstacles and limits came up and how we solved them with the help of the BOSH core development team. Learn how we monitor the directors, be it via logging and metrics or performance indicators. We’ll also show you how we automate BOSH itself to ensure the best experience for end users, and to keep them blissfully unaware of the complexity of the processes working on their behalf After this talk you will also be able to run at least 1,200 deployments on your directors.

As service providers and primary code contributors in the Islandora Community, discoverygarden encounters customers who are ingesting, accessing, and storing high volumes of data. For example, a customer who had 150,000 objects in 2012 now has three million objects and expectations to grow to five million in the very short term. This is increasingly common.
As repositories grow in size they can encounter poor performance, particularly during large ingests and derivative generation. To accommodate growing repositories caching mechanisms, infrastructure changes, and code updates are necessary.
The presentation will explore customer case studies that demonstrate interim solutions and the extensive, ongoing research and development to find long-term solutions.
"Orphans, Corruption, Careful Write, and Logging", by Ann W. Harrison and Jim Starkey. A frequent question on the Firebird Support list is "Gfix thinks my database is corrupt. How can I fix it?" The best answer may be to fix gfix itself so it reports benign errors differently from actual corruption. The most common errors reported by gfix can simply be ignored. From the beginning of InterBase to now, gfix is the least interesting of the utilities, so it's had little attention. However it requires a great deal of knowledge of database internals, so it's not easily replaced by a separately developed tool. So, from 1984 until now, gfix has reported major corruption and benign errors as if they were all the same.
What's a benign error? Usually, it's an artifact from the sudden death of a Firebird server that leaves obsolete record versions or even whole empty pages orphaned - neither released nor in use. Orphans represent lost space, but have no other damaging effect on the database. Orphaned record versions and pages occur because Firebird carefully orders its page writes to avoid the need for before or after logs. Database management systems that rely on logging for durability and recovery write each piece of data twice - once to a log and later to the database. Careful write requires discipline in programming. In 1984, careful write had performance advantages that more than made up for the need for careful programming.
This talk and paper explore the cause of "orphan" pages and record versions, Firebird's careful write I/O architecture, and the trade-offs between careful write and logging today.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
