The document discusses the Sun StorageTek 2500 series arrays. It provides context on challenges facing IT today such as data growth, storage utilization, and complexity. The 2500 arrays are presented as affordable primary and secondary storage solutions for entry-level and workgroup environments. Key features highlighted include simple management, small footprint, strong performance for the price, and reliable data protection.
Oracle Automatic Storage Management has proven to be one of the most widely adopted new features in Oracle Database 10g and it has been dramatically improved in the later 11g releases. This presentation will explain what changes are solved by ASM, how these challenges are solved, what barriers there are to ASM adoptions, and how 11g Release 2 addresses these barriers.

Deduplication reduces the amount of disk storage needed to retain and protect data by ratios of 10-30x and greater, making a disk a cost-effective alternative to tape. Data on disk is available online and onsite for longer retention periods, and restores become fast and reliable. Storing only unique data on disk also means that data can be cost-effectively replicated over existing networks to remote sites for disaster recovery and consolidated tape operations.

Database performance in blade environments: Dell PowerEdge M1000e vs. Cisco U...Principled Technologies
Scalable and reliable compute performance, in conjunction with your 16Gb Fibre Channel capability with SAN-based storage, means you don’t have to worry about your application VMs losing performance as your business grows. In our tests, the Dell PowerEdge M1000e blade environment delivered up to 91.7 percent greater throughput while running a virtualized OLTP database workload than the similarly priced Cisco UCS 5108 blade environment. More importantly, the Dell M1000e blade environment delivered consistent scaling as we added blade servers, in contrast to the performance degradation we observed in the Cisco UCS 5108 blade environment. The Dell M1000e also left room to grow within the 10U, with eight additional half-height slots available for compute nodes in the future, whereas the Cisco UCS 5108 blade environment would require a second enclosure to house additional blades. Finally, both solutions were similarly priced, so there is no additional cost associated with the advantages of the Dell environment. For applications demanding dense compute environments, high throughput, and lower response rates, companies will find the Dell PowerEdge M1000e blade environment better able to scale to meet predictable performance requirements as their business grows.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
