After the HS2 fiasco, perhaps the journey is over for heavy engineering in Britain – The Guardian

Notebook

It was always going to be complicated driving a great railway through expensive, scenic, Tory-voting countryside; best stick to broadband and buses

Sources connected to the now-truncated HS2 project tell me of the insane difficulty, expense and delay of building an underground electricity supply to one section of the line. The cost of feasibility work went from 3.5m to 12m, as 18 options were explored for achieving this mundane task. The preferred one proved unacceptably hazardous to some canal bridges under which it would pass. The next foundered when a landowner demanded 2.8m for permission for the supply to cross their property, to which HS2 objected, only to see the figure raised to 7m by an independent valuer. The option eventually chosen started construction earlier this year, three years behind schedule, at several times the original intended cost.

Its hardly surprising, then, that the project as a whole proved expensive. At the root of the problem is the High Speed Rail Act of 2017, which places an overwhelming obligation for permissions and consents on contractors, which in turn reflects the fact that barrelling a huge railway through scenic, prosperous and Conservative-voting parts of the home counties was always going to be complicated. Sunaks cancellation was pointlessly destructive, but at least it gives pause for thought: perhaps this densely populated country, with its well-guarded natural beauties, is no longer the place it was when Brunel and Stephenson drove great railways across the landscape.

We might perhaps turn our genius to designing a future beyond heavy engineering, that pays more attention for example to improving peoples lives in the places where they live. Maybe things like buses, local trains and broadband that work well boring, but more useful, and less environmentally damaging.

I appreciate the demand of the Royal Borough of Greenwich for the complete demolition of a 23-storey development called Mast Quay, and the restoration of the land to its former condition, on account of 26 major deviations from its planning consent. These include the failure to provide gardens, play areas, wheelchair access and underground car parking as promised, as well as shrunken balconies and a significant cheapening of its external appearance. Its good to see a local authority stand up to the greed and arrogance of a property company. To demolish an entire brand-new building, though, seems extraordinarily wasteful and environmentally reckless. Could the developers not pay a colossal fine instead, equivalent to the cost of demolition and reconstruction, to be spent on affordable housing? Or donate all or some of the buildings flats for the same purpose, while also paying for the missing gardens and play areas? If planning law doesnt allow for such actions, it should be changed.

Its an under-recognised fact of architectural history that, much of the time, builders in the past were aiming for the biggest, brightest, most colourful and impactful structures they could achieve. Its only the effect of time, and the disappearance of paint and decorations, that make us think of the past as mostly grey and brown. Georgian Illuminations, an exhibition at Sir John Soanes Museum in London, shows how the supposedly sober architects of the 18th century liked to dress up buildings like the Bank of England with expensively dazzling lighting effects, using the then up-to-date technology of whale oil lamps. In which case we might embrace the Sphere, the recently opened Las Vegas venue whose internal and external surfaces consist of vast curved digital screens. Theres a proposed London version that may well have unacceptable impacts on nearby homes, but the thing itself just takes those Georgian lights to their next step.

ABET accreditation reaffirms UTSA’s excellence in engineering … – UTSA

ABET has also accredited, for the first time, UTSAs new bachelors program in chemical engineering. The B.S. in chemical engineering was established in Fall 2017 and designed with a rigorous curriculum and a low faculty-to-student ratio that enables close interactions between students and professors. Additionally, the program provides experiential learning opportunities to make students more competitive job candidates upon graduation and to position them for success in the workforce. Alumni are pursuing graduate degrees at elite chemical engineering programs in the nation.

Having an ABET-accredited program will provide us with another springboard to grow connections with the chemical industries, especially in Texas, said Nehal Abu-Lail, interim chair of the UTSA Department of Biomedical and Chemical Engineering. This accreditation will also enable us to attract the most competitive students to our program. It is a testimonial to the high-quality education we are providing to our students.

Brey added that ABET accreditation for young degree programs is a significant milestone. The B.S. in chemical engineering was retroactively accredited to 2020, ensuring that all of UTSAs undergraduate chemical engineering students, including the inaugural graduating class, is able to hold up a degree from an ABET accredited program.

The reviewers were particularly impressed by our facilities, specifically the Margie and Bill Klesse Unit Operations Teaching Laboratory, which offers students outstanding opportunities for hands-on application of classroom theory, he added.

UTSA chemical engineering major Yamur Hocaolu said, I am beyond happy and proud of UTSA for achieving the ABET accreditation in the chemical engineering program. As a current junior chemical engineering student, my time here has provided me with many opportunities, such as being an undergraduate research assistant, Klesse Student Ambassador, and overall, just giving me the opportunity to academically and professionally develop as a female engineer.

Hocaolu added, I originally began studying chemical engineering due to my deep interest in math and chemistry, and I seek to utilize this degree to help combat environmental issues. Thanks to UTSA, I am able to have this opportunity and to truly help my community.

School of Engineering expands first-year advising program – University of Virginia The Cavalier Daily

A new advising plan for first-year students has been implemented at the School of Engineering this year to improve upon the current embedded advising program. Under the new system, students will take foundational engineering courses over a full year with their advisor as their instructor, someone who is also a faculty member within the School of Engineering.

First-year Engineering students will take a sequence of courses titled Engineering Foundations throughout their first year. These courses will be taught by a team of six advisors who will focus solely on advising the students in their classes. Classes will be capped at 48 students per section, and each advisor will have around three groups of students. The classes will meet twice a week throughout the year.

William Guilford, associate dean for undergraduate affairs for the School of Engineering, said this embedded model brings more consistency to the quality and frequency of advising. Guilford has served as an academic advisor in the past for these courses.

It [will] definitely help with the social aspects of these courses, Guilford said. Having taught a pilot myself, when the students know you're their academic advisor, and they know that you are there, not just to teach them, but to support them that makes a palpable difference in the classroom.

Revamping undergraduate student advising has long been central to the Universitys 2030 plan last month, the Board of Visitors discussed progress made in both the Engineering School and the College to continue strengthening advising.

In past years, first-year students took a one semester-long course in the fall titled Introduction to Engineering with their advisor. Advisors included members of the Engineering faculty from around the school. After declaring a major in the spring of their first year, students received a new advisor specific to their department within the school.

Though the new expanded program had pilot phases during the past two years, this year will mark the first full-scale implementation, with first-year students taking the two engineering foundations courses over a full academic year as opposed to one semester.

This years new team of advisors, a combination of new faculty and faculty already at the University, will only instruct first-years in engineering foundations courses. The advisors underwent training this summer to prepare them for the role. Throughout this year, they will continue to undergo monthly training surrounding advising and teaching their introductory courses.

Leyf Starling, First Year Engineering Center lecturer and an instructor on this team, said the training was primarily devoted to developing curricula for these courses and better understanding the Universitys network of resources. According to Starling, continuous training throughout the year will enhance the programs success.

We have weekly meetings where we will talk about advising issues and I feel like we have incredible support, Starling said. If any questions come up and we don't know the answers, then we can help find the answers.

Another advisor who participated in this training, Engineering Associate Prof. Esther Tian, said that students have received the new program positively, aligning with the excitement and hard work put in by advisors.

Seeing the excitement in the classroom, and then the connection they have already started [forming] among themselves, I think this is really something good, Tian said.

Discussions surrounding these changes began in 2019 but implementation was delayed by the onset of the COVID-19 pandemic, Guilford said. After returning in person plans were made to implement them during this academic year.

First-year Engineering student Albert Sein said advisors who instruct courses often gain a more detailed understanding of individual students needs.

I think it's really helpful to have [my advisor] as a professor because she gets to know the type of student that you are and your strengths and weaknesses because shes grading your work, Sein said.

The School of Engineering will continue to build upon other facets of the embedded advising model, which includes an Assistant Dean of Students and Center for Diversity in Engineering, who specifically serve Engineering students.

In recent years, Engineering has also added two embedded Counseling and Psychological Services counselors for its students, as well as a specialist from the Student Disability Access Center, who focus on fulfilling the needs of students within the school.

Guilford said stronger advising supports overall learning within the Engineering school. The advising classes offer a chance for instructors to work hands-on with students through projects that introduce both engineering concepts and interpersonal connections.

You're able to explore a lot of different things in a very simple format and the very first week of class, when everyone's just kind of still trying to figure out how to find a classroom, Guilford said.

ST Engineering showcases applications of new technologies to stay ahead of disruption – CIO

The advent of new technologies has accelerated the rate of innovation and disrupted the business landscape as we know it. As the pace of innovation speeds up, tomorrows front runners are those who readily embrace disruptive technologies to spearhead new business models and capture new avenues of growth.

The good news is that many organisations are cognisant of the key role that new technologies play. Foundrys CIO Tech Priorities 2023 found that IT leaders are investing in technologies that provide greater efficiencies, better security, and improved end-user experience, with most actively researching or piloting projects around artificial intelligence (AI) and machine learning, data analytics, automation, and IT/OT intelligence.

This is the reality futurist Mike Walsh shared during his keynote speech at ST Engineerings InnoTech Conference 2023: that 21st-century companies will be defined by their mastery of technologies such as AI, automation, and algorithms, driven by the rapid pace of change.

Think about how technological advances have influenced consumers to gradually shift their focus from products to platforms, transactions to experiences, and data to decisions. This, in turn, is forcing businesses to rethink the way they operate, engage, and go to market.

At the same time, the influx of new technologies and new business models is introducing myriad vulnerabilities and expanding the threat surface area. Consider how the time to execute ransomware attacks has been reduced by 94 percent. What used to take attackers at least two months to deploy in 2019 is only taking them under four days in 2021.

To sharpen their competitive edge and succeed in 2023, companies need to do what felt unthinkable just years ago: to do more, do better, and do so with less. This means adapting to the needs of consumers, businesses, and governmentsas well as changing market conditionsby becoming more efficient, agile, and smart.

This is an approach ST Engineering adheres to, with its recent showcase on leveraging new technologies at InnoTech Conference 2023. These revolve around accelerating industry transformation, particularly among healthcare, front liners, and defence, to help organisations thrive in an evolving technology landscape.

Thriving in todays volatile business climate means having to take a measured and balanced approach to implementing digital strategies, while keeping an inquisitive and nimble attitude to embrace innovations. Consider both the upsides and downsides to every disruptive innovation and develop applications that are smart, secure, and sustainable, without losing your focus on solving real-world challenges, says Low Jin Phang, President, Digital Systems, ST Engineering.

These use cases by ST Engineering are underpinned by three pillars:

Streamlining complex operations with AI as the next frontierThe rise of video content poses a unique challenge to businesses when it comes to sifting through them to make data-driven decisions, especially given the sheer volume of data that video content generates.

This is a challenge AGIL Vision seeks to solve. The video analytics platform allows users to perform more intuitive searches within video streams via the use of natural-language prompts to identify specific objects, such as umbrellas, backpacks, vehicles, and firearms, as well as human behaviour such as pickpocketing or climbing over fences.

By leveraging state-of-the-art Generative AI models and advanced language-vision intelligence, image and language encoding and decoding capabilities were integrated to improve the breadth of search with a higher degree of accuracy. These can be applied to security surveillance in instances such as:

The launch of AGIL Vision, which is an all-in-one, plug-and-play solution, helps users to easily deploy and set up on-premise to enhance security and data privacy significantly, as it eliminates the need to send data externally. At the same time, the model can be fine-tuned to meet the needs of organisations, thus empowering staff to enhance their productivity and efficiency without having to employ additional manpower.

Then there is the Remote Virtual Assistant, a head-mounted device that can be used withinhospitals. This allows nurses to consult doctors through secure voice and video calls during medical emergencies, with doctors able to connect remotely and offer timely interventions. This is bolstered by generative AI to help prepare notes and reports automatically. This significantly reduces administrative tasks for nurses, enabling them to focus more time on life-saving activities.

Improving security and safety via robotics and advanced connectivityThe use of unmanned devices and vehicles is growing increasingly common in various industries, from traffic monitoring to construction, due to its promise of enhanced efficiency and most importantly, its ability to keep employees safe especially in hazardous environments.

ST Engineering has recently completed a proof-of-concept, involving 5G connectivity, at Sentosa island. This is a security operation involving a command centre, multiple unmanned aerial drones, unmanned ground vehicles, and smart video cameras.

With these connected by a private and secure 5G network, this system has leveraged AI-driven video analytics to improve operational efficiency and uncover potential threats. Such network connectivity will also enable ST Engineering to develop high-performance unmanned vehicles that can perform tasks that are too hazardous for humans.

Defending against cyberattacks with quantum securityAgainst a backdrop of increasingly sophisticated cyberattacks, organisations should exercise caution even when adopting innovative new technologies, which can greatly expand their attack surface. Staying proactive against threats is crucial to strengthening their security posture while keeping employees educated about the potential cybersecurity pitfalls.

To this end, quantum security, a powerful, developing field in cybersecurity, will become a crucial tool against cybercrime. With threat actors actively stealing confidential data, quantum computers can encrypt and decrypt these data in the future to ensure the privacy and integrity of data.

In particular, ST Engineerings host of quality security solutions, which leverage Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) techniques, ensure that network architectures are secure against attacks. In particular, QKD is built upon quantum mechanics such that data can be transmitted while staying resistant to attacks that may be effective against traditional encryption methods. This is coupled with Quantum Resistant Encryption (QRE) protocols and safeguards.

Furthering their digital transformation in the face of rampant digital disruption is no small undertaking for many organisations. But while they are eager to move forward, insufficient budgets, competing priorities, and the lack of right skill sets may hinder them from moving forward. By investing in the right technologies, organisations can capitalise on innovations to drive growth, even with lesser resources.

In the next two to five years, the business landscape will see more new digital technologies emerging. Its thus important for organisations to embrace disruptive technologies and translate them into solutions that can deliver real value. These would be applications that have wide-ranging use cases, and can transform how we live, work, and play, concluded Low.

A more effective experimental design for engineering a cell into a … – MIT News

A strategy for cellular reprogramming involves using targeted genetic interventions to engineer a cell into a new state. The technique holds great promise in immunotherapy, for instance, where researchers could reprogram a patients T-cells so they are more potent cancer killers. Someday, the approach could also help identify life-saving cancer treatments or regenerative therapies that repair disease-ravaged organs.

But the human body has about 20,000 genes, and a genetic perturbation could be on a combination of genes or on any of the over 1,000 transcription factors that regulate the genes. Because the search space is vast and genetic experiments are costly, scientists often struggle to find the ideal perturbation for their particular application.

Researchers from MIT and Harvard University developed a new, computational approach that can efficiently identify optimal genetic perturbations based on a much smaller number of experiments than traditional methods.

Their algorithmic technique leverages the cause-and-effect relationship between factors in a complex system, such as genome regulation, to prioritize the best intervention in each round of sequential experiments.

The researchers conducted a rigorous theoretical analysis to determine that their technique did, indeed, identify optimal interventions. With that theoretical framework in place, they applied the algorithms to real biological data designed to mimic a cellular reprogramming experiment. Their algorithms were the most efficient and effective.

Too often, large-scale experiments are designed empirically. A careful causal framework for sequential experimentation may allow identifying optimal interventions with fewer trials, thereby reducing experimental costs, says co-senior author Caroline Uhler, a professor in the Department of Electrical Engineering and Computer Science (EECS) who is also co-director of the Eric and Wendy Schmidt Center at the Broad Institute of MIT and Harvard, and a researcher at MITs Laboratory for Information and Decision Systems (LIDS) and Institute for Data, Systems and Society (IDSS).

Joining Uhler on the paper, which appears today in Nature Machine Intelligence, are lead author Jiaqi Zhang, a graduate student and Eric and Wendy Schmidt Center Fellow; co-senior author Themistoklis P. Sapsis, professor of mechanical and ocean engineering at MIT and a member of IDSS; and others at Harvard and MIT.

Active learning

When scientists try to design an effective intervention for a complex system, like in cellular reprogramming, they often perform experiments sequentially. Such settings are ideally suited for the use of a machine-learning approach called active learning. Data samples are collected and used to learn a model of the system that incorporates the knowledge gathered so far. From this model, an acquisition function is designed an equation that evaluates all potential interventions and picks the best one to test in the next trial.

This process is repeated until an optimal intervention is identified (or resources to fund subsequent experiments run out).

While there are several generic acquisition functions to sequentially design experiments, these are not effective for problems of such complexity, leading to very slow convergence, Sapsis explains.

Acquisition functions typically consider correlation between factors, such as which genes are co-expressed. But focusing only on correlation ignores the regulatory relationships or causal structure of the system. For instance, a genetic intervention can only affect the expression of downstream genes, but a correlation-based approach would not be able to distinguish between genes that are upstream or downstream.

You can learn some of this causal knowledge from the data and use that to design an intervention more efficiently, Zhang explains.

The MIT and Harvard researchers leveraged this underlying causal structure for their technique. First, they carefully constructed an algorithm so it can only learn models of the system that account for causal relationships.

Then the researchers designed the acquisition function so it automatically evaluates interventions using information on these causal relationships. They crafted this function so it prioritizes the most informative interventions, meaning those most likely to lead to the optimal intervention in subsequent experiments.

By considering causal models instead of correlation-based models, we can already rule out certain interventions. Then, whenever you get new data, you can learn a more accurate causal model and thereby further shrink the space of interventions, Uhler explains.

This smaller search space, coupled with the acquisition functions special focus on the most informative interventions, is what makes their approach so efficient.

The researchers further improved their acquisition function using a technique known as output weighting, inspired by the study of extreme events in complex systems. This method carefully emphasizes interventions that are likely to be closer to the optimal intervention.

Essentially, we view an optimal intervention as an extreme event within the space of all possible, suboptimal interventions and use some of the ideas we have developed for these problems, Sapsis says.

Enhanced efficiency

They tested their algorithms using real biological data in a simulated cellular reprogramming experiment. For this test, they sought a genetic perturbation that would result in a desired shift in average gene expression. Their acquisition functions consistently identified better interventions than baseline methods through every step in the multi-stage experiment.

If you cut the experiment off at any stage, ours would still be more efficient than the baselines. This means you could run fewer experiments and get the same or better results, Zhang says.

The researchers are currently working with experimentalists to apply their technique toward cellular reprogramming in the lab.

Their approach could also be applied to problems outside genomics, such as identifying optimal prices for consumer products or enabling optimal feedback control in fluid mechanics applications.

In the future, they plan to enhance their technique for optimizations beyond those that seek to match a desired mean. In addition, their method assumes that scientists already understand the causal relationships in their system, but future work could explore how to use AI to learn that information, as well.

This work was funded, in part, by the Office of Naval Research, the MIT-IBM Watson AI Lab, the MIT J-Clinic for Machine Learning and Health, the Eric and Wendy Schmidt Center at the Broad Institute, a Simons Investigator Award, the Air Force Office of Scientific Research, and a National Science Foundation Graduate Fellowship.

Tissue Engineering and Biomanufacturing Research Opportunity – ISS National Lab

KENNEDY SPACE CENTER (FL), October 4, 2023 A new research announcement to leverage the unique environment of the International Space Station (ISS) to advance tissue engineering and biomanufacturing is now open. The ISS National Laboratory is soliciting concepts for applied research and technology development for regenerative medicine applications seeking to demonstrate space-based manufacturing and production activities for terrestrial applications. Through this research announcement, multiple projects will be awarded funding to support project costs, hardware and integration costs, and flight allocation to the orbiting laboratory.

Through in-space production and manufacturing efforts, the ISS National Lab seeks to enable new business models that can grow capital investment and develop a robust market in low Earth orbit (LEO). Both NASA and the ISS National Lab have prioritized utilization of the space station for in-space production applications and manufacturing opportunities, and this research announcement reflects a desire to build on this growing area of emphasis.

The ISS National Lab is seeking proposals in the areas of regenerative medicine and biofabrication as well as associated technologies that may benefit from the unique conditions on the space station. Of particular interest are studies that propose to:

As a recent example, Redwire Space launched an updated BioFabrication Facility (BFF) to further bioprinting capabilities in the absence of gravity. The company successfully bioprinted a complete human meniscus (a protective piece of cartilage in the knee joint) in space for the first time and returned it to Earth earlier this month. This significant milestone helps pave the way to one day being able to print tissues and organs in space for patients on Earth and future space travelers. The space environment is beneficial for biofabrication because microgravity allows delicate tissues to mature and strengthen without collapsing under their own weight as they do on Earth. On an upcoming Commercial Resupply Services mission to the space station, a prior ISS National Lab Research Announcement recipient will launch neural organoid models to better understand mechanisms behind human neurodegenerative disease. The investigation, led by the National Stem Cell Foundation, uses induced pluripotent stem cells derived from patients with Parkinsons disease and primary progressive multiple sclerosis to develop a brain organoid model that will be tested on Earth and in microgravity, where the onset and progression of the disease is accelerated. This accelerated model of disease can advance biomarker discovery for improved diagnosis and accelerate drug discovery and development for the treatment of neurodegenerative disease.

Findings from such investigations will help improve patient care on Earth and help establish a robust and sustainable economy in LEO.

This research announcement follows a two-step proposal process. The Step 1: Concept Summary is due at the close of business on November 20, 2023. Only approved Step 1 concepts will be invited to submit a full proposal. For more information on this research announcement, including how to attend an upcoming webinar slated for October 13, 2023, please visit our research announcement overview webpage.

Austin Engineering eyes US expansion with Wyoming government … – International Mining

Posted by Daniel Gleeson on 9th October 2023

Austin Engineering says it has achieved a significant development milestone and moved a step closer to undertaking a major rebuild and expansion of its US manufacturing base in Casper, Wyoming, after securing the benefit of a $20 million grant and loan package through the City of Mills, Wyoming and the Wyoming Business Council.

The funds are designated for the construction of a proposed new circa-69,000-sq.ft (6,410-sq.m) manufacturing facility and a 15,000-sq.ft paint and blast building on the site of Austins existing manufacturing facility, on land already owned by Austin. The grant and loan facility is made to the City of Mills, which will build the facility to Austins requirements, and lease it to the company.

North America is Austins strongest performing business unit on a revenue and margin basis, the company says. The expansion of the Casper facility would significantly increase the manufacturing capacity for Austins customised mining haul truck bodies primarily for the US and Canada. It will also be capable of manufacturing other product lines such as mining buckets, water tanks, and tyre handlers.

The $15 million grant and $5 million loan package application was approved by the State Loan and Investment Board. It requires final approval from the Wyoming State Attorney General and the Austin Board after a full review of the business case. The Austin Board does not expect to give final development approval for the new facility until the end of the year after a full business case has been completed and assessed.

If final approval is given, construction could commence sometime in late financial year 2024 (to end-June 2024) following board approval, final facility design and permitting, with the build forecast to take up to two years. The construction will not affect the existing production output and it is envisaged that it would create circa-50 new permanent jobs in addition to the current 110-strong staff base.

As part of the investment, Austin would need to commit a further $5 million capital funding for the facility, the majority of which would need to be spent during its 2025 and 2026 financial years.

As part of the package, Austin has agreed to donate approximately 25 acres (10.1 ha) of land, that is mostly industrially unusable, due to being part of a floodplain, and not required for production or storage, to the City of Mills for future community development projects and public facilities.

In the last 12 months, Austin has undertaken expansions of its Indonesian and Chilean-based facilities, enhancing both output and manufacturing efficiencies across the business. However, this investment would be the biggest undertaken to expand capacity.

Austin CEO and Managing Director, David Singleton, said: We are extremely pleased to have been awarded this funding package from the Wyoming Business Council to undertake a much-needed rebuild of our existing facilities. As well as being part of the local community in the City of Mills since 1940, and Wyoming since 1938, our Casper facility is the hub of our rapidly growing North American operations.

North Americas financial year 2023 revenues were up 13% year-on-year. We had recently taken a short-term lease on a facility to meet increased orders in the region. A larger, permanent facility would enable Austin to increase its output further in line with expected growth.

This rebuild will also ensure Austin US stays at the forefront of designing and building customised truck bodies, mining buckets and other equipment. The determination to improve mining efficiency in North America has seen a strong growth in demand for trays and buckets, particularly in recent years, and is expected to continue.

An Engineering Perspective on Cloud Cost Optimization: Erik … – InfoQ.com

A single line of code can shape an organization's financial future. Erik Peterson, the CTO and founder at CloudZero, presentedan engineeringperspective on cloud cost optimization during day three at QCon San Francisco. His session was part of the "Architecting for the Cloud" track.

Petersons talk focusedon five real examples of "million-dollar lines of code" and how this can challenge conventional views on engineering's pivotal role in cloud cost optimization. He startedhis talk by emphasizing the importance of considering costs as a critical metric often overlooked in engineering decisions. He statedthat every engineering decision is a purchasing decision, and harboring unwarranted skepticism about cloud services can become a self-fulfilling prophecy.

Next, Peterson discussed five practical examples with code samples, which include optimizing debug lines to curb logging costs, streamlining API usage to reduce expenses, being mindful of database write volumes to control costs, ensuring resource cleanup in infrastructures as code, and the potential benefits of rewriting code related to content delivery networks.

One of the examples was regarding a debugging statement that led to high costs:

In the code sample, Peterson showed the Lambda function in question (obfuscated from the real function):

The problem was the line of code with the logger.debug statement that generated the cost. The solution was to delete that line.

Peterson's key takeawaysfrom theexamples included:

And provided a quote from Donald Knuth:

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%

He continued that all the examples he provided were only problems at scale. Peterson statedthat software engineers deploying to the public cloud should think about the following questions iteratively and over time, not all at once:

Regarding the last question, he stresses that the metric to answering the money question is not money (cost) but tracking your desiredCloud Efficiency Rate (CER).

Peterson states that the CER should become a non-functional requirement for any cloud project, with defined stages to aid prioritization. These stages are:

Lastly, Peterson ended the session with a final thought from Sir Tony Hoare:

I call it my billion-dollar mistake. It was the invention of the null reference in 1965. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years.

Note that there is a QCon London session on the null reference billion-dollar mistake: Null References: The Billion Dollar Mistake
