We’ve covered the four-day workweek in several issues: In the pre-pandemic issue 6-10, we made the case that a four-day workweek could be the norm by 2050. In issue 9-05, the cover article also said the four-day workweek may be coming and potentially much sooner than 2050 because of the pandemic. Neither of these articles, however, looked at the positive impact a four-day workweek could have on the planet and our ecosystem.

When the pandemic hit, the world as we knew it changed dramatically with everyone at home, transportation infrastructure stopped and heavy industrial production drastically curtailed. Emissions from driving, flying and industrial output were dramatically reduced. Air quality in cities around the world showed marked improvement, while global emissions plummeted.

In May 2021, environmental and social justice collective Platform London released a report detailing the ecological impact of a shorter work week. From the earliest days of the pandemic, it was apparent that fewer people commuting translated quickly to reduced pollution, clearer skies, and less congestion on the roads. The impact was global, with Americans reporting less smog in Los Angeles and Europeans famously spotting dolphins in the canals of Venice. While some of this may be exaggerated, the benefits of fewer rush hour commuters are not. Fewer people heading to the office also means a reduction in electricity consumption from fewer lights, air conditioners and elevators running.

Many estimates put the reduction in carbon footprint at around 30% simply by offering one full day off per week. A more modest 10% reduction in hours (roughly three to four hours a week for most full-time workers) still translates to a 14.6% decrease in carbon emissions.

“The one thing we do know from lots of years of data and various papers and so forth is that the countries with short hours of work tend to be the ones with low emissions, and work time reductions tend to be associated with emission reduction,” said Juliet Schor, an economist and sociologist at Boston College who researches work, consumption and climate change.

It’s what you might call a “potential triple-dividend policy, so something that can benefit the economy, society and also the environment,” said Joe O’Connor, chief executive of the nonprofit group 4-Day Week Global. “There are not many policy interventions that are available to us that could potentially have the kind of transformative impact that reduced work time could have.”

Part of the problem is that we can’t forecast what workers will do with that additional day. Many believe, and international studies like those recently done in Iceland prove, that people will eventually gravitate into more eco-friendly activities like hiking, camping and other outdoor activities. But, if people choose to spend their extra time off traveling, particularly if they use planes or automobiles, we may not see any material eco-related benefits.
​
“When we talk about the four-day workweek and the environment, we focus on the tangible, but actually, in a way, the biggest potential benefit here is in the intangible,” O’Connor said. “It’s in the shift away from a focus on hard work to a focus on smart work. It’s the cultural change in how we work and the impact that could have on how we live, and I think that’s the piece that’s really revolutionary.”

Record heat all over the globe is now a potentially bigger threat to ongoing data center operations than cybercrime. In late July, Google Cloud’s data centers in London went offline for a day because of cooling failures. Oracle’s cloud-based data center, also in London, was hit and went offline, causing outages for US clients.

The World Meteorological Organization (WMO) says there’s a 93% change that one year between 2022 and 2026 will be the hottest on record. “For as long as we continue to emit greenhouse gases, temperatures will continue to rise,” says Petteri Taalas, WMO secretary general. “And alongside that, our oceans will continue to become warmer and more acidic, sea ice and glaciers will continue to melt, sea level will continue to rise, and our weather will become more extreme.”

A survey conducted by the Uptime Institute, a digital services standards agency, found that 45% of all US data centers have experienced an extreme weather event that threatened their ability to provide uninterrupted service.

The problem with both US-based and European centers is that their cooling systems were designed for a cooler planet than we have today. Newer data centers are now being constructed with a forecasted weather scenario to better plan for much higher temperatures.

Most data centers don’t operate at full capacity, but recent Cushman & Wakefield research shows that eight data center markets worldwide out of 55 they investigated operate at 95% or higher capacity. These centers are only strained by high temperatures a few days a year and they have been able to adjust loads to compensate for the heat. 

As climate change alters our temperatures permanently, data centers will have to improve their cooling systems so that continuous service can be assured.

“There are a deceptively large number of legacy data center sites built by banks and financial services companies needing to be refreshed and refitted,” says Simon Harris, head of critical infrastructure at data center consultancy Business Critical Solutions. As part of that rethink, Harris advises companies to look at design criteria that can cope with climate change, rather than solely minimizing its effects. “It’ll be bigger chiller machines, machines with bigger condensers, and looking more at machines that use evaporative cooling to achieve the performance criteria needed to ensure that for those days things are still in a good place,” he says.

Companies are trying novel approaches to dealing with the climate issues. Microsoft ran a three-year trial of a data center set 117 feet below the sea offshore of Scotland to insulate it from temperature fluctuations. Other companies are building centers in even more northern climates, but that probably won’t be a viable solution for those organizations who use edge computing and need their centers close to where data is consumed, often in hotter, urban areas.
​
We all have to do everything we can to reduce the impact of climate change, but now is the time for all data center management personnel to better plan for the increased temperatures we will experience for the foreseeable future.

Large data centers need power backup to operate without interruption. They rely on large banks of lithium-ion batteries to provide the instantaneous power when the normal power supplied by the local grid fails. Those lithium-ion batteries could soon be used to help local power grids manage energy demand.

Any city or region that gets its power from renewables is subject to the whim of the weather. Unlike fossil-based energy, renewable energy sources ebb and flow. The battery systems these grids use provide power when the renewable sources ebb and recharge when they flow.

Microsoft realized it could partner with local power grids where its data centers are located around the world and offer to store that renewable power in their battery backup systems. Today, sophisticated data centers operate with what are known as “uninterruptible power supply systems.” These systems include a bank of batteries which kick in the instant the power goes out and may operate for only a few minutes until the backup generators are up and running.

Microsoft’s newest data center in Dublin, Ireland, is due to come online in 2023 and it is planned as the first center to partner with a local power grid. The plan would be to have the data center’s large battery installation provide backup for when the grid sees more energy demand than it can supply. But, instead of only responding to outages, it might actually prevent them.

The company isn’t publicly sharing how much energy its Dublin battery installation will prove to the grid. But, from information provided by Microsoft’s Datacenter Advanced Development Group, we know that a typical center uses “tens of megawatts of power.”

To put the battery’s size into perspective, a single megawatt generated by a power plant can provide electricity for several hundred homes.

Microsoft has tested the concept on a small scale in Chicago, IL and Quincy, Washington in the past. But because almost 35% of all of Ireland’s electricity come from wind farms, this was one of the best places to set up a full commercial partnership.
​
The company currently operates over 200 data centers worldwide and has plans to build between 50 and 100 new centers a year through the rest of this decade. Given Microsoft’s commitment to reduce its greenhouse gas emissions, it needs more renewable energy for its data centers. The partnerships they plan with local power grids should be real win-win scenarios.

At the end of May, Walmart announced an expansion of its drone-delivery service. By the end of the year, the retail giant plans to offer the service from 34 locations in six states. When the service started, it was only offered from a single store in Arkansas and with this expansion; they hope to reach up to 4 million households.

The service will operate between 8AM and 8PM and deliver packages weighing less than 10 pounds. The service will be operated by a company Walmart has invested in--DroneUp. There will be a charge of $3.99 for the delivery. The order is packed into a box and a DroneUp pilot flies the drone to the customer’s location, easing the box gently down on the front lawn with a claw-like device at the end of a sturdy cable.
This program expansion is forecasted to take hundreds of deliveries within a few months to more than a million drone deliveries a year. Walmart is clearly targeting the one or two items that are purchased with quick last-minute trips. The press release stated that the top-selling item at one of the early hubs is Hamburger Helper.

The Wall Street Journal reported that both UPS and FedEx are experimenting with drones but aren’t offering an actual service yet. Alphabet (Google’s parent) has its own drone service called Wing with limited offerings in Virginia and Texas. Wing is also operating in Australia and through the first quarter of 2022, they claim deliveries of over 200,000 parcels.
​
And we can’t forget Amazon. As we wrote in Technology This Week Issue 8-49, the company is still experiencing problems with its drone efforts. The big difference for Amazon’s program is that they want the drones to be autonomous rather than piloted. Because of their commitment to “certified pilots,” Walmart will have a tougher time scaling up their efforts. Drone flights, by regulation, must be ‘line-of-sight’ flights. Stores will have to have control towers in their parking lots and are limited to a 1.5-mile radius for deliveries.
We will all keep our eyes on Walmart during the rest of 2022 to see if they will be successful in their new drone efforts. It could be a chance for Walmart to surpass Amazon in a critical technology area in the new retail arena!

Walmart was late in actively addressing competition with Amazon in ecommerce. In its new efforts to meet Amazon’s challenge, the company announced that it has plans to open four new fulfillment centers.

These fulfillment centers are where online orders will be packed and shipped. They are the first of a new breed of logistics for Walmart. The technology-heavy investments they are making involve robotics, machine learning and artificial intelligence.

Walmart said they were working with Knapp, an international logistics provider, to replace their current 12-step manual process with a new 5 steps and doubling the number of orders a location can fulfill in a day. Instead of moving product with people, the new approach will have robots shuttle skiffs to stagers directly, eliminating the need for floor personnel to walk up to nine miles or more a day.

"These four next-generation [fulfillment centers] alone could provide 75% of the U.S. population with next- or two-day shipping on millions of items," David Guggina, Senior Vice President of Innovation and Automation at Walmart U.S., wrote in a blog post.

When the four new centers join the company’s existing 31 dedicated e-commerce fulfillment centers, Walmart believes it will be able to reach 95% of the U.S. population with next- or two-day shipping. And with its 4,700 physical stores, the company could offer same-day delivery to about 80% of the U.S.

Both Walmart and Amazon are focusing on their weaknesses as compared to each other. Walmart is spending billions on logistics and automation and Amazon is spending billions on new physical stores, particularly for groceries (where Walmart dominates.)

Walmart’s new fulfillment centers will be located in Joliet, Illinois; McCordsville, Indiana; Lancaster, Texas; and Greencastle, Pennsylvania—with each planning to hire over 1,000 new workers. 
​
Amazon currently has 253 fulfillment centers, 110 sortation centers, and 467 delivery stations in North America, not to mention hundreds of thousands of drivers and over 100 Amazon Air cargo aircraft at the end of 2021.

Edge technologies are projected to experience the highest investment increase in 2022, growing 76% to $462,000 according to a new Gartner, Inc. survey.

Looking back to 2021, 5G drew the highest average investment in 2021, with survey respondents reporting an average of $465,000 invested in the technology. This was followed by IoT at $417,000 and edge technologies (i.e., edge AI and edge computing) at $262,000. 

The edge architecture is allowing AI to become more actionable. Moving AI inferencing closer to the point of data generation is making the edge more intelligent, which is improving decision-making within organizations and data-driven outcomes. In conducting AI inferencing on the edge, the data is processed in real time to generate actionable insights for decision-makers.

It makes sense that among the reasons organizations are using edge technologies and 5G are to improve employee productivity, augment existing products and services by making them more connected and intelligent, and automate business processes. Asset intensive industries such as manufacturing, natural resources and energy are among the early adopters of ET to solve core business problems. 

It’s interesting to note that the decisions to invest in these emerging technologies (ET) no longer solely rest with IT. The survey showed that Boards of Directors are among the main decision makers for ET investments in over half of surveyed organizations, just behind CIOs and CTOs, signaling that the business has more confidence in the ROI these technologies bring.

In fact, counter to conventional thinking, most survey respondents reported that ET investments are meeting or exceeding user expectations. When enterprises are choosing between two vendors’ ET offerings, the vendors’ ability to provide demonstrable use cases and a track record of success ultimately clinches the win. Product managers should look to focus on these success stories and ensure short deployment/ implementation timelines when targeting business users to adopt ET.

Gartner surveyed 500 global respondents from mid-sized and larger organizations in September and October 2021 to understand buying behavior when investing in emerging technologies.

Predictions indicate that a nanometer-sized wave-based computer could solve equations in a fraction of the time of their larger, electronic counterparts.  
Booting up your laptop may seem like an instantaneous process, but in reality, it’s an intricate dance of signals being converted from analog waveforms to digital bytes to photons that deliver information to our retinas. For most computer uses, this conversion time has no impact. But for supercomputers crunching reams of data, it can create a serious, energy-consuming slowdown. Researchers are looking to solve this problem using analog, wave-based computers, which operate solely using light waves and can perform calculations faster and with less energy. Now, Heedong Goh and Andrea Alù from the Advanced Science Research Center at the City University of New York present the design for a nano-sized wave-based computer that can solve mathematical problems, such as integro-differential equations, at the speed of light.
One route that researchers have taken to make wave-based analog computers is to design them into metamaterials, materials engineered to apply mathematical operations to incident light waves. Previous designs used large-area metamaterials—up to two square feet ( ∼0.2 m2)—limiting their scalability. Goh and Alù have been able to scale down these structures to the nanoscale, a length scale suited for integration and scalability.
The duo’s proposed computer is made from silicon and is crafted in a complex geometrical nanoshape that is optimized for a given problem. Light is shone onto the computer, encoding the input, and the computer then encodes the solution to the problem onto the light it scatters. For example, the duo finds that a warped-trefoil structure can provide solutions to an integral equation known as the Fredholm equation.
Goh and Alù’s calculations show that their nano-sized wave-based computers should be able to solve problems with near-zero processing delay and with negligible energy consumption.

The BlackByte ransomware gang appears to have made a comeback after targeting at least three U.S. critical infrastructure sectors, according to an advisory from the FBI and the Secret Service.

BlackByte is a ransomware-as-a-service (RaaS) operation that leases out its ransomware infrastructure to others in return for a percentage of the ransom proceeds. The gang emerged in July 2021 when it began exploiting software vulnerabilities to target corporate victims worldwide. While BlackByte had some initial success—security researchers tracked attacks against manufacturing, healthcare, and construction industries in the U.S., Europe, and Australia—the gang hit a rough patch months later when cybersecurity firm Trustwave released a free decryption tool that allowed BlackByte victims to recover their files for free. The group’s simplistic encryption techniques led some to believe that the ransomware was the work of amateurs; the ransomware downloaded and executed the same key to encrypt files in AES, rather than unique keys for each session.

Despite this setback, it appears the BlackByte operation is back with a vengeance. In an alert posted in mid-February, the FBI and the Secret Service (USSS) warned that the ransomware gang had compromised multiple U.S. and foreign businesses, including “at least” three attacks against U.S. critical infrastructure, notably government facilities, financial services, the food industry, and agriculture.

The advisory, which provides indicators of compromise to help network defenders identify BlackByte intrusions, was released just days before the ransomware gang claimed to have encrypted the network belonging to the San Francisco 49ers. BlackByte disclosed the attack the day before the Super Bowl by leaking a few files it claims to have been stolen.

Brett Callow, a ransomware expert and threat analyst at Emsisoft, says that while BlackByte isn’t the most active RaaS operation, it’s been steadily racking up victims over the past few months. However, he adds that because of recent action by the U.S. government against ransomware actors, the gang might take a cautious approach.

“The FBI and Secret Service advisory states that BlackByte has been deployed in attacks on at least three U.S. critical infrastructure sectors, including government. Interestingly, no such organizations are listed on the gang’s leak site, which could indicate that those organizations paid, that no data was exfiltrated or that BlackByte chose not to release the exfiltrated data,” he said. “That final option is not unlikely: since the arrests of members of REvil, the gangs seem to have become more cautious about releasing data, and especially with U.S. organizations.”

Callow said that while all signs suggest BlackByte is based in Russia, since the ransomware, like REvil, is coded not to encrypt the data of systems that use Russian or Commonwealth of Independent States (CIS) languages. That “shouldn’t be taken to mean the attack was carried out by individuals based in Russia or the CIS.”
​
“Affiliates may not be located in the same county as the individuals who run the RaaS,” he added. “They could be based anywhere—including the U.S.”

If you’ve noticed cryptic new icons popping up on your phone next to the 5G logo, you’re not alone. Carriers are expanding their 5G networks in a big way this year, and those little “UW” and “UC” logos you’re suddenly seeing represent the different varieties of 5G you’re encountering in the wild. Like Pokémon, but way more confusing.

Isn’t 5G just… 5G? Nope. There are low, mid, and high-band varieties of 5G spectrum. They all provide different levels of data speeds, and all major US carriers use all three. Naturally, they also have different names for them. Depending on your carrier, you may see abbreviations pop up next to the 5G symbol on your phone when you’re connected to the corresponding network. Here’s a quick guide to the different varieties of 5G in the US and the abbreviations carriers have assigned to them.

5G Spectrum Basics. Broadly speaking, low-band 5G has widespread signal reach, but speeds aren’t much faster than 4G LTE (if at all). High-band 5G is very fast—download a movie in seconds fast—but the signal is extremely limited. Then there’s mid-band 5G, which offers a kind of middle ground between the two: far-reaching signal and speeds that are noticeably faster than 4G, though not shockingly fast like high-band.

Verizon
5G UW: Verizon refers to both its high-band and mid-band 5G as Ultra Wideband (UW). Until recently, UW referred only to the high-band network, also called mmWave. Verizon put a lot of energy into building and promoting this network, but even in the limited areas where it exists, the signal can be difficult to find. Starting in 2022, Verizon started lighting up new mid-band 5G spectrum in major cities and classified it, too, as Ultra Wideband. Not confusing at all.

If you see the 5G UW icon on your phone, chances are you’re on the mid-band network. If you’re on mmWave, you’ll notice a big difference in data speeds. But if your data just seems noticeably fast, not ridiculously fast, then you’re probably on mid-band.

5G Nationwide: Verizon refers to its low-band 5G as 5G Nationwide. You’re connected to this network if you just see a 5G logo on your phone without “UW” next to it. And if your reaction to seeing that 5G icon pop up is something like “Huh, this doesn’t seem any faster than 4G,” you’re not imagining things. It’s generally not much faster than LTE. Certain Verizon plans, like its basic 5G Start unlimited plan, only include this low-band version of 5G. 

AT&T
5G Plus: A “5G+” logo on your screen means you’re connected to either AT&T’s high-band or mid-band spectrum. AT&T has put much less effort behind building out a high-band network outside of stadiums and airport terminals, so you’re not likely to encounter it just out-and-about. As of early 2022, mid-band AT&T spectrum is also sort of scarce since the carrier is taking a “kill two birds with one stone” approach to its mid-band expansion. A 5G logo without the “Plus” refers to the carrier’s low-band 5G network, which, it’s worth repeating, is not much faster than LTE.

T-Mobile
5G UC: T-Mobile’s “Ultra Capacity” network technically includes high-band 5G, but the bulk of the network—and T-Mobile’s advertising—is centered on the mid-band spectrum included in the name. While Verizon and AT&T are just getting their mid-band networks up and running, T-Mobile got a head start with the 2.5GHz mid-band spectrum it picked up when it acquired Sprint. If you see that “5G UC” logo on your phone, you can bet that’s the spectrum you’re connected to. 
​
Extended Range: A 5G logo without “UC” indicates that you’re connected to low-band 5G, which T-Mobile calls “Extended Range.” Again, it’s not much faster than LTE, but coverage is more widespread than mid-band or high-band 5G. If you’ve seen a 5G logo on your T-Mobile phone and been unimpressed by the data speeds, that might be why.

Here are a few FinTech firms that are emblematic of how technology innovation is shaping the future of money across a variety of financial services.

Versapay—Accounts receivable
In its quest to rid companies of paper checks, Toronto-based Versapay has developed one of the first collaborative accounts receivable platforms, combining advanced invoicing, automation, and payments technology to deliver improvements and efficiencies for its 250,000 business clients. It has mushroomed during the pandemic, which fueled a demand for digital payments, including the digitizing of accounts receivable services. In a recent interview, Versapay CEO Craig O'Neill said a large majority of finance leaders will adopt digitized payments in the next few years. "Surveys show that 93% of finance leaders are saying they're going to digitize how they do business on both the accounts payable and accounts receivable side. There's going to be a sea change over the next couple of years, which will really change the face of business: paper goes away completely, including check stock, and will set people free to work wherever they want," he said.  

BestEgg—Personal lending and financial management resources
This Wilmington, Del.-based FinTech, is on a mission to help people feel more confident about their everyday finances by making money accessible through fast, simple, and easy personal loans. BestEgg has created a proprietary AI platform to deliver digital products including loans for debt consolidation, credit card refinancing, home improvement, moving, vacation and baby adoption. BestEgg recently introduced an online financial health platform to bolster confidence for consumers in the wake of the COVID-19 pandemic, which has had a debilitating effect on many peoples' finances. "The future of digital finance is human," says Sabrina DeVito, chief strategy officer for Marlette Holdings, which operates BestEgg. "Digital can come across as cold, but the winners are going to be those who not only use digital to create extraordinary experiences but also are human in how they come across," she said.

Kabbage—Small business financing
Small businesses took a beating during the coronavirus pandemic—large numbers shut down permanently, crippling local communities both economically and socially. Fortunately, more small businesses are forming in the shadow of the pandemic, and one FinTech is helping to make that possible. Kabbage, backed by American Express, is a one-stop FinTech resource for small businesses, providing access to cash flow solutions such as business checking, flexible funding, and payment processing services. It recently launched Kabbage Funding, which provides flexible lines of credit between $1,000 and $150,000, and Kabbage Checking for online business checking accounts.
"We saw a technology opportunity; a way to use an API to automate serving a business that couldn't have been served previously," said Kathryn Petralia, co-founder of Kabbage. Petralia says what she's seeing with small businesses is that there's more support by many other companies to serve these unserved small businesses. "They're a vital part of the economy—a vital part of job growth and so now we can do that using technology where we couldn't do it before because it was always hard to market to small business. But thanks to the data and these new technology platforms, we can do it," Petralia said.

UpTip—Cashless tipping
This new startup replaces cash tipping with an e-payment platform and enables users to provide ratings on service providers such as wait staff and limousine drivers. Companies are given a QR code after registering with UpTip. Customers scan the code on their smartphone to view the company's profile, give a star rating, leave feedback and, of course, provide a tip. Tips are deposited directly into a debit card or bank account of choice.
​
The travel and hospitality industry is still struggling in the wake of COVID and so are the people whose lives and livelihoods have depended on tipping. Eric Plam, UpTip's founder, believes the pandemic has been a catalyst to help people figure out how much they value people who serve them and the services they provide. UpTip will help collect the data used to determine how much service staff are valued. "We really believe that personality, enthusiasm and merit should be rewarded and so this is one reason we enjoy tipping and that's one thing we do with our service and ratings platform—we try to raise people who are doing a great job because we want to help them advance in their careers", Plam said.
