Lightning Talk #9: How UX and Data Storytelling Can Shape Policy by Mika Aldabaux singapore
How can we take UX and Data Storytelling out of the tech context and use them to change the way government behaves?
Showcasing the truth is the highest goal of data storytelling. Because the design of a chart can affect the interpretation of data in a major way, one must wield visual tools with care and deliberation. Using quantitative facts to evoke an emotional response is best achieved with the combination of UX and data storytelling.

Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
By David F. Larcker, Stephen A. Miles, and Brian Tayan
Stanford Closer Look Series
Overview:
Shareholders pay considerable attention to the choice of executive selected as the new CEO whenever a change in leadership takes place. However, without an inside look at the leading candidates to assume the CEO role, it is difficult for shareholders to tell whether the board has made the correct choice. In this Closer Look, we examine CEO succession events among the largest 100 companies over a ten-year period to determine what happens to the executives who were not selected (i.e., the “succession losers”) and how they perform relative to those who were selected (the “succession winners”).
We ask:
• Are the executives selected for the CEO role really better than those passed over?
• What are the implications for understanding the labor market for executive talent?
• Are differences in performance due to operating conditions or quality of available talent?
• Are boards better at identifying CEO talent than other research generally suggests?
We discuss the concepts behind CrXPRT 2015, its development process, as well as the application’s structure. We also describe the component tests and detail the statistical processes used to calculate expected battery life.
We discuss the newest version of MobileXPRT, including its development process, new features, and details of the individual test workloads. We also explain exactly how the benchmark calculates results.

This guide is an extract from the two and three day course provided by me. It spans the complete testing lifecycle and the tool usages. It will look at the infrastructure implications and testing practices in formal and in agile teams. But, the main focus stays on the usages of the Microsoft Visual Studio testing tools, the knowledge you need to get starting with it, the practices you must have to work with it in real live and how you can bend the tools, with extensibility and normal use to your team needs.
The course and this guide is work in progress. It is not a testing training (I expect you already have testing knowledge), if you need that test process information I refer to the TMap website from Sogeti where you can find tons of information.

Investing in GenAI: Cost‑benefit analysis of Dell on‑premises deployments vs....Principled Technologies
Conclusion
Diving into the world of GenAI has the potential to yield a great many benefits for your organization, but it first requires consideration for how best to implement those GenAI workloads. Whether your AI goals are to create a chatbot for online visitors, generate marketing materials, aid troubleshooting, or something else, implementing an AI solution requires careful planning and decision-making. A major decision is whether to host GenAI in the cloud or keep your data on premises. Traditional on-premises solutions can provide superior security and control, a substantial concern when dealing with large amounts of potentially sensitive data. But will supporting a GenAI solution on site be a drain on an organization’s IT budget?
In our research, we found that the value proposition is just the opposite: Hosting GenAI workloads on premises, either in a traditional Dell solution or using a managed Dell APEX pay-per-use solution, could significantly lower your GenAI costs over 3 years compared to hosting these workloads in the cloud. In fact, we found that a comparable AWS SageMaker solution would cost up to 3.8 times as much and an Azure ML solution would cost up to 3.6 times as much as GenAI on a Dell APEX pay-per-use solution. These results show that organizations looking to implement GenAI and reap the business benefits to come can find many advantages in an on-premises Dell solution, whether they opt to purchase and manage it themselves or choose a subscription-based Dell APEX pay-per-use solution. Choosing an on-premises Dell solution could save your organization significantly over hosting GenAI in the cloud, while giving you control over the security and privacy of your data as well as any updates and changes to the environment, and while ensuring your environment is managed consistently.
Workstations powered by Intel can play a vital role in CPU-intensive AI devel...Principled Technologies
In three AI development workflows, Intel processor-powered workstations delivered strong performance, without using their GPUs, making them a good choice for this part of the AI process
Conclusion
We executed three AI development workflows on tower workstations and mobile workstations from three vendors, with each workflow utilizing only the Intel CPU cores, and found that these platforms were suitable for carrying out various AI tasks. For two of the workflows, we learned that completing the tasks on the tower workstations took roughly half as much time as on the mobile workstations. This supports the idea that the tower workstations would be appropriate for a development environment for more complex models with a greater volume of data and that the mobile workstations would be well-suited for data scientists fine-tuning simpler models. In the third workflow, we explored tower workstation performance with different precision levels and learned that using 16-bit floating point precision allowed the workstations to execute the workflow in less time and also reduced memory usage dramatically. For all three AI workflows we executed, we consider the time the workstations needed to complete the tasks to be acceptable, and believe that these workstations can be appropriate, cost-effective choices for these kinds of activities.
Enable security features with no impact to OLTP performance with Dell PowerEd...Principled Technologies
Get comparable online transaction processing (OLTP) performance with or without enabling AMD Secure Memory Encryption and AMD Secure Encrypted Virtualization - Encrypted State
Conclusion
You’ve likely already implemented many security measures for your servers, which may include physical security for the data center, hardware-level security, and software-level security. With the cost of data breaches high and still growing, however, wise IT teams will consider what additional security measures they may be able to implement.
AMD SME and SEV-ES are technologies that are already available within your AMD processor-powered 16th Generation Dell PowerEdge servers—and in our testing, we saw that they can offer extra layers of security without affecting performance. We compared the online transaction processing performance of a Dell PowerEdge R7625 server, powered by AMD EPYC 9274F processors, with and without these two security features enabled. We found that enabling AMD Secure Memory Encryption and Secure Encrypted Virtualization-Encrypted State did not impact performance at all.
If your team is assessing areas where you might be able to enhance security—without paying a large performance cost—consider enabling AME SME and AMD SEV-ES in your Dell PowerEdge servers.

In high-temperature test scenarios, a Dell PowerEdge HS5620 server continued running an intensive workload without component warnings or failures, while a Supermicro SYS‑621C-TN12R server failed
Conclusion: Remain resilient in high temperatures with the Dell PowerEdge HS5620 to help increase efficiency
Increasing your data center’s temperature can help your organization make strides in energy efficiency and cooling cost savings. With servers that can hold up to these higher everyday temperatures—as well as high temperatures due to unforeseen circumstances—your business can continue to deliver the performance your apps and clients require.
When we ran an intensive floating-point workload on a Dell PowerEdge HS5620 and a Supermicro SYS-621CTN12R in three scenario types simulating typical operations at 25°C, a fan failure, and an HVAC malfunction, the Dell server experienced no component warnings or failures. In contrast, the Supermicro server experienced warnings in all three scenario types and experienced component failures in the latter two tests, rendering the system unusable. When we inspected and analyzed each system, we found that the Dell PowerEdge HS5620 server’s motherboard layout, fans, and chassis offered cooling design advantages.
For businesses aiming to meet sustainability goals by running hotter data centers, as well as those concerned with server cooling design, the Dell PowerEdge HS5620 is a strong contender to take on higher temperatures during day-to-day operations and unexpected malfunctions.

Three AMD EPYC processor-based two-processor solutions outshined comparable Intel Xeon Scalable processor-based solutions by handling more Redis workload transactions and requests while consuming less power
Conclusion
Performance and energy efficiency are significant factors in processor selection for servers running data-intensive workloads, such as Redis. We compared the Redis performance and energy consumption of a server cluster in three AMD EPYC two-processor configurations against that of a server cluster in two Intel Xeon Scalable two-processor configurations. In each of our three test scenarios, the server cluster backed by AMD EPYC processors outperformed the server cluster backed by Intel Xeon Scalable processors. In addition, one of the AMD EPYC processor-based clusters consumed 20 percent less power than its Intel Xeon Scalable processor-based counterpart. Combining these measurements gave us power efficiency metrics that demonstrate how valuable AMD EPYC processor-based servers could be—you could see better performance per watt with these AMD EPYC processor-based server clusters and potentially get more from your Redis or other data intensive applications and workloads while reducing data center power costs.
Improve performance and gain room to grow by easily migrating to a modern Ope...Principled Technologies
We deployed this modern environment, then migrated database VMs from legacy servers and saw performance improvements that support consolidation
Conclusion
If your organization’s transactional databases are running on gear that is several years old, you have much to gain by upgrading to modern servers with new processors and networking components and an OpenShift environment. In our testing, a modern OpenShift environment with a cluster of three Dell PowerEdge R7615 servers with 4th Generation AMD EPYC processors and high-speed 100Gb Broadcom NICs outperformed a legacy environment with MySQL VMs running on a cluster of three Dell PowerEdge R7515 servers with 3rd Generation AMD EPYC processors and 25Gb Broadcom NICs. We also easily migrated a VM from the legacy environment to the modern environment, with only a few steps required to set up and less than ten minutes of hands-on time. The performance advantage of the modern servers would allow a company to reduce the number of servers necessary to perform a given amount of database work, thus lowering operational expenditures such as power and cooling and IT staff time for maintenance. The high-speed 100Gb Broadcom NICs in this solution also give companies better network performance and networking capacity to grow as they embrace emerging technologies such as AI that put great demands on networks.
Boost PC performance: How more available memory can improve productivityPrincipled Technologies
With more memory available, system performance of three Dell devices increased, which can translate to a better user experience
Conclusion
When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.

Upgrade your cloud infrastructure with Dell PowerEdge R760 servers and VMware...Principled Technologies
Compared to a cluster of PowerEdge R750 servers running VMware Cloud Foundation 4.5
Conclusion
If your company is struggling with underperforming infrastructure, upgrading to 16th Generation Dell PowerEdge servers running VCF 5.1 could be just what you need to handle more database throughput and reduce vSAN latencies. We found that a Dell PowerEdge R760 server cluster running VCF 5.1 processed over 78 percent more TPM and 79 percent more NOPM than a Dell PowerEdge R750 server cluster running VCF 4.5. It’s also worth noting that the PowerEdge R750 cluster bottlenecked on vSAN storage, with max write latency at 8.9ms. For reference, the PowerEdge R760 cluster clocked in at 3.8ms max write latency. This higher latency is due in part to the single disk group per host on the moderately configured PowerEdge R750 cluster, while the better-configured PowerEdge R760 cluster supported four disk groups per host. As an additional benefit to IT admins, we also found that the embedded VMware Aria Operation adapter provided useful infrastructure insights.
Based on our research using publicly available materials, it appears that Dell supports nine of the ten PC security features we investigated, HP supports six of them, and Lenovo supports three features.

Compared to the Supermicro management portfolio
Conclusion
Choosing a vendor for server purchases is about more than just the hardware platform. Decision-makers must also consider more long-term concerns, including system/data security, energy efficiency, and ease of management. These concerns make the systems management tools a vendor offers as important as the hardware.
We investigated the features and capabilities of server management tools from Dell and Supermicro, comparing Dell iDRAC9 against Supermicro IPMI for embedded server management and Dell OpenManage Enterprise and CloudIQ against Supermicro Server Manager for one-to-many device and console management and monitoring. We found that the Dell management tools provided more comprehensive security, sustainability, and management/monitoring features and capabilities than Supermicro servers did. In addition, Dell tools automated more tasks to ease server management, resulting in significant time savings for administrators versus having to do the same tasks manually with Supermicro tools.
When making a server purchase, a vendor’s associated management products are critical to protect data, support a more sustainable environment, and to ease the maintenance of systems. Our tests and research showed that the Dell management portfolio for PowerEdge servers offered more features to help organizations meet these goals than the comparable Supermicro management products.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Introduction
The purpose of the CrXPRT benchmark is to reliably evaluate the performance and battery life of devices
running the Google Chrome operating system (OS). The benchmark provides an intuitive user interface,
a runtime allowing it to be completed within half of a typical work day, and easy-to-understand results.
About the benchmark
The CrXPRT benchmark is published as an application (app) for the Chrome OS. It is intended to be
installed on devices running the Chrome OS (Chromebooks) and launched from the Chromebook Apps
center. The benchmark is divided into two test modes, performance and battery life, that run
independently of each other. The benchmark calculates performance scores and estimates battery life
using results from tests based on real-world productivity and media scenarios.
Some of the CrXPRT workload material is based on tests included in WebXPRT 2013. In addition, the
workload contains activities which are not part of WebXPRT, and some of the tests have been modified
to highlight specific features within the Chrome OS. The performance test includes seven individual
workloads. The battery-life test includes all seven workloads from the performance test, plus media
playback, gaming, and wait time scenarios.
After completing a test run, the benchmark displays a results page. The performance test produces an
overall performance score and individual workload scores. The battery life test produces an estimated
battery life expressed in hours and minutes, a separate performance score, and a frames per second
(FPS) rate for the HTML5 gaming component. The battery life performance score is different than the
main performance test score, so the two scores should not be compared. The following sections
describe the performance and battery life tests in more detail.
About the performance test
Portions of the performance test mode are adapted from the WebXPRT 2013 framework, which
contains many elements common to Chromebook usage. The performance suite includes Web browsing
and JavaScript workloads from WebXPRT 2013 along with additional workloads based on Portable
Native Client (PNaCl) and WebGL technologies. The seven performance scenarios are Photo Effects, Face
Detection (JavaScript), Offline Notes, Stock Portfolio Dashboard, DNA Sequence Analysis, 3D Shape with
WebGL, and Photo Collage using PNaCl. Further details about each workload can be found in Table 1.
The performance suite runs for seven iterations and reports an overall score and individual workload
scores. The performance test takes approximately 20 minutes to complete.
About the battery life test
The battery life test includes all seven workloads from the performance suite, plus video playback, audio
playback, and HTML5 gaming scenarios. It also incorporates realistic periods of wait time, for a total of
11 components. Table 1 describes the battery-life workloads in more detail.
3. Page 3 of 14 BenchmarkXPRT Development Community
Each iteration of the battery life test lasts for 30 minutes and is comprised of approximately 18 minutes
of active workloads and 12 minutes of wait/idle time. However, since different devices work at different
speeds, the exact amount of idle time will vary by device. By default, the test runs a total of seven
iterations, so the battery life test will take 3 hours and 30 minutes to complete.
You may also set the test to run for 4.5 hours, 5.5 hours, or until the battery is exhausted. These
extended tests require more iterations of the workload than the standard seven-iteration test, but are
the same as the standard test in all other respects.
The battery life test produces detailed results information including an estimated battery life with a 95
percent confidence interval, a performance score based on the seven performance suite workloads, and
a frames per second (FPS) rate from the HTML5 gaming scenario. The detailed results information also
includes the test’s exact duration, starting and ending battery levels for each iteration, and the
percentage of battery level drop for each iteration, so that testers can compare the expected battery life
to the actual elapsed time if they desire.
Results of the complete rundown test and the seven-iteration test should be very similar. However,
because it uses a large number of iterations, the rundown test will generally have a smaller confidence
interval.
Test workloads
Table 1 describes the CrXPRT performance and battery life workloads. All seven workloads from the
performance test are included in the battery-life test, but the battery-life test also includes video
playback, audio playback, HTML5 gaming, and wait time components.

Results data collection
In order to help us with future benchmark development, CrXPRT collects test information and some data
about the device that produced those results, and stores the information in a secure database. To see
the fields CrXPRT collects, click here.
If you do not want to provide system information such as processor and memory type, you have the
option to opt out of providing that information by unchecking a box on the Start Test page.
As with WebXPRT, we may quote aggregate results and result ranges, such as high and low scores, the
number of results, or the average score, but we will never make individual CrXPRT results public without
the tester’s permission. In addition, CrXPRT does not report, and therefore Principled Technologies
cannot make public, identifying personal or corporate data, or any other potentially confidential
information.
