Maglev trains use magnetic levitation to float above the track and propel vehicles without friction. They can reach speeds over 500 km/h, faster than F1 cars or traditional trains. Maglev trains have been introduced in several countries since the 1960s for their high speed, low noise, and ability to operate in all weather conditions with minimal maintenance requirements compared to mechanically-powered trains. Shanghai, China claims the fastest maglev train at 501 km/h.

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.
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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

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.
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:

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.

Maglev train
1. Maglev Train<br />What is a Maglev Train?<br />A Maglev Train is a system of transportation that suspends guides and propels vehicles.<br />How does it work using magnetic force?<br />In current electromagnetic suspension (EMS) systems, the train levitates above a steel rail while electromagnets, attached to the train, are oriented toward the rail from below. Magnetic attraction varies inversely with the cube of distance, so minor changes in distance between the magnets and the rail produce greatly varying forces.<br />In electrodynamics (the force of electricity in motion) suspension (EDS), both the rail and the train exert a magnetic field, and the train is levitated by the repulsive force between these magnetic fields. The magnetic field in the train is produced by either superconducting magnets, or by an array of permanent magnets. The repulsive force in the track is created by an induced magnetic field in wires or other conducting strips in the track.<br />Advantages<br />Maintenance Requirements of Electronic versus Mechanical Systems: Traditional rail is subject to the wear and tear of miles of friction on mechanical systems and increases exponentially with speed, unlike maglev systems. This basic difference is the huge cost difference between the two modes and also directly affects system reliability, availability and sustainability.<br />All-Weather Operations: Maglev trains currently in operation are not stopped, slowed, or have their schedules affected by snow, ice, severe cold, rain or high winds. This cannot be said for traditional friction-based rail systems. Also, maglev vehicles accelerate and decelerate faster than mechanical systems regardless of the slickness of the guide way or the slope of the grade because they are non-contact systems.<br />Efficiency: Due to the lack of physical contact between the track and the vehicle, maglev trains experience no rolling resistance, leaving only air resistance and electromagnetic drag, potentially improving power efficiency.<br />Noise: Because the major source of noise of a maglev train comes from displaced air, maglev trains produce less noise than a conventional train at equivalent speeds.<br />Countries that had introduced this technology<br />New York, United States 1968<br />In 1961, when he was delayed during rush hour traffic on the Throgs Neck Bridge, James Powell, a researcher at Brookhaven National Laboratory, thought of using magnetically levitated transportation to solve the traffic problem. Powell and BNL colleague Gordon Danby jointly worked out a Maglev concept using static magnets mounted on a moving vehicle to induce electrodynamics lifting and stabilizing forces in specially shaped loops on a guide way. <br />Hamburg, Germany 1979<br />Transrapid 05 was the first maglev train with long stator propelling force licensed for passenger transportation. In 1979, a 908 m track was opened in Hamburg for the first International Transportation Exhibition. There was so much interest that operations had to be extended three months after the exhibition finished, having carried more than 50,000 passengers. It was reassembled in Kassel in 1980.<br />Birmingham, United Kingdom 1984–1995<br />The world's first commercial automated maglev system was a low-speed maglev shuttle that ran from the airport terminal of Birmingham International Airport to the nearby Birmingham International railway station between 1984–1995. The length of the track was 600 meters, and trains quot;
flewquot;
at an altitude of 15 millimeters, levitated by electromagnets, and propelled with linear induction motors. It was in operation for nearly eleven years, but obsolescence problems with the electronic systems made it unreliable in its later years. One of the original cars is now on display at Railworld in Peterborough, while the RTV31 hover train vehicle is preserved on the Nene Valley Railway in Peterborough.<br />Japan 1985<br />In Japan, there are two independently developed Maglev trains. One is HSST by Japan Airlines and the other, which is more well-known, is JR-Maglev by Japan Railways Group.<br />Vancouver, Canada, and Hamburg, Germany 1986-1988<br />In Vancouver, Canada (1986), the JR-Maglev was exhibited at Expo 86. Guests could ride the train along a short section of track at the fairgrounds. In Hamburg, Germany (1988), the TR-07 in international traffic exhibition (IVA88) performed Hamburg.<br />Berlin, Germany 1989–1991<br />In West Berlin, the M-Bahn was built in the late 1980s. It was a driverless maglev system with a 1.6 km track connecting three stations. Testing in passenger traffic started in August 1989, and regular operation started in July 1991. Although the line largely followed a new elevated alignment, it terminated at the U-Bahn station Gleisdreieck, where it took over a platform that was then no longer in use; it was from a line that formerly ran to East Berlin. After the fall of the Berlin Wall, plans were set in motion to reconnect this line. Deconstruction of the M-Bahn line began only two months after regular service began that was called Pundai project and was completed in February 1992.<br />What is the average speed of the maglev train and which country claimed the fastest moving one?<br />The average speed of the maglev train is 3720 mph and China (Shanghai) claimed the fastest moving one. Maglev vehicle achieved a Chinese record speed of 501 km/h at a non-commercial top speed. The journey was designed to connect Shanghai Pudong International Airport quickly to the outskirts of central Shanghai where passengers could interchange for their final destinations in the city centre.<br />Which is faster, F1 racing car or Maglev train?<br />A maglev train is faster. The fastest F1 racing car can only reach a speed of around 350 km/h while the fastest maglev train can reach a speed of 501 km/h.<br />Would you want the maglev train to be introduced in Singapore? If yes, why? If not, why not?<br />Yes, I would like to have a maglev train in Singapore as it can move in a faster than the normal MRT trains we have in Singapore and it creates lesser noise than the MRT trains.<br />Why this video was chosen amongst the many thousands online?<br />Link: http://www.youtube.com/watch?v=1pXlvIpP_d8&feature=fvst <br />I think is video was chosen amongst the many thousands online because it provided relevant information about the maglev trains and it has a clear video too. The maglev train is useful to us because it is fast and convenient.<br />Source:<br />http://www.youtube.com<br />http://en.wikipedia.org/ <br />
