Read the article below from The Economist....Less globalisation, More Tech. It is a "thick" read but the article has excellent points about how our current situation could shape business technology.

Pick 5 Points from the Article and add them to our shared Google Doc. In our shared doc provide supporting detail why those points were the ones you picked.

Sometimes change is so vast and dislocating that it is hard to tell disaster from opportunity. In March Ocado, a British online grocer, saw its servers so overloaded that it suspected hackers. “We thought that we were under a denial-of-service attack,” says Tim Steiner, the company’s boss. In fact, Britons were desperately trying to arrange to get food and drink deliveries for the weeks ahead. After Boris Johnson, the prime minister, announced a national lockdown the site filled three weeks’ worth of delivery slots in an hour.

Companies for which the ill wind of covid-19 has blown some good have been very much in the minority. In February, even as stockmarkets began to crash, business leaders could console themselves with three observations. First, they bore no blame for the crisis. Some downturns, such as the dotcom bust of 2000-01 and the financial crisis of 2007-09 are seen through a quasi-biblical lens of retribution—just deserts for orgies of speculation. This was more like a tsunami, or a war; its casualties had some hope of being treated as innocent victims deserving of support, rather than the authors of their own fate.

Second, most companies—particularly in America—went into the crisis in pretty solid shape; employment was booming, order books were relatively full and the easing of America’s trade war with China augured well. Third, within days of global markets melting down China was tentatively reopening some factories and lifting some of its draconian lockdowns. This suggested a v-shaped recovery, or at worst a u-shaped one, something requiring not life-and-death measures but a battened-down Sufi stoicism: “This, too, shall pass.” As Dara Khosrowshahi, who runs Uber, said confidently as late as early March, “At least from what we’ve seen the bounceback can be pretty quick.”

Unfortunately, many European countries and some American states immediately began to impose social-distancing measures and, soon thereafter, lockdowns. Businesses found themselves looking into the abyss of a largely moribund economy. According to the International Labour Organisation sectors now facing a severe decline in output, and thus a high risk of lay-offs and furloughs, employ almost 38% of the global workforce: some 1.25bn workers (see chart 1).

Government handouts in America and Europe should ease the pain of some of that unemployment—if fully implemented and if the benefit systems work. But many of the proposed beneficiaries, such as florists, gyms and bakeries, will still go short. Whether they scrape by or go under, that will prolong the slump in consumer confidence—as will the possibility of a second wave of illness after restrictions are lifted. One pessimistic Wall Street banker talks of a future neither v-shaped, u-shaped or even w-shaped, but “more like a bathtub”.

Yet even as they walk through the valley of the shadow of death, chief executives and corporate strategists are beginning to look to the post-covid world to come. What they think they see, for good or ill, is an acceleration. Three existing trends—the deglobalisation unpicking the business world that grew up in the 2000s; the infusion of data-enabled services into ever more aspects of life; a consolidation of economic power into the hands of giant corporations—look likely to proceed at a faster rate than before, and perhaps to go further, too. Optimists—and business folk tend to look on the bright side—see this acceleration as offering new possibilities for reinvention, even resurrection. Pessimists see inefficiencies and insularity weighing on profitability for many years to come.

Seasick

Whether or not such doldrums lurk in the future, the present is a mad swell of chop and change in which the fortunes of different regions and sectors vary wildly.

China’s economy shows distinct signs of recovery. Bernstein, an investment firm, notes that many of the swanky metropolitan restaurants it tracks there were full by the first weekend in April. That said, many migrant workers have yet to return to work. Air and rail traffic remain severely curtailed, as do car sales. The Chinese, though, are at least making cars to sell. European and American plants are shuttered.

Neither is the gloom within countries evenly spread. Some sectors are doing worse than others, and in all the fortunes of the most and least resilient are far apart (see chart 2). Should the coming recession not kill off animal spirits entirely, there will be lots of opportunities for corporate upheaval, takeovers and strategic shifts.

China’s government may encourage its state-owned firms to go global by buying distressed car companies in Europe. The share price of Daimler is less than half what it was when Geely, a Chinese carmaker, bought a 10% stake in 2018. Car companies may also see offers from technology giants keen to improve co-operation between metal bashers and the engineers of autonomy—currently wary at best. The healthier airlines, such as Qantas and iag, owner of British Airways, will snap up airport slots from their bankrupt rivals and may try to acquire others only just staying aloft. Private-equity firms, which have mountains of committed investor cash, may start buying up fundamentally sound but impecunious suppliers in various industries, aware that when demand returns such companies will see its first fruits. Anand Mahindra, chairman of the Mahindra group, one of India’s largest conglomerates, says that as well as big corporations buying smaller ones, many smaller firms will look to merge with peers.

Around the world, small and medium-sized firms are particularly exposed. In America, a survey published on April 3rd by MetLife, an insurer, and the us Chamber of Commerce found that 54% of non-sole-proprietor firms with fewer than 500 employees were either closed or expected to close in coming weeks. It has been a similar story in China. As well as driving unemployment, this has systemic implications. Though such firms are often relatively inefficient, the nimbler ones can play a role in supply chains that would be hard to duplicate. Aware of this, some big firms, such as Unilever, are attempting to buoy up suppliers by paying them more quickly.....

.......Take China and its supply-chain primacy first. By 2017, when average Chinese manufacturing wages had become as high as those in the poorer parts of Europe, it was clear that the logic which saw a large fraction of the world’s supply chains pass through the country needed re-examining. The former boss of a big American company’s Chinese operations says that in the past few years the trade war and other risks of business disruption saw many global firms seek to reduce their dependency on China. One of their favoured strategies was to put more business into factories elsewhere in Asia.

But the acute stage of China’s covid-19 crisis made it clear how essential China remains as a provider of inputs to such factories elsewhere in Asia and around the world. “What people thought was a global supply chain was a Chinese supply chain,” says Mr Mahindra. The quest for supply chains independent of Beijing needs to go further, and deeper.

Joerg Wuttke, president of the eu Chamber of Commerce in China, says that if there is one lesson people are drawing from the pandemic in this regard it is that “single source is out and diversification is in.” In other words, companies do not just need suppliers outside China. They need to build out their choice of suppliers, even if doing so raises costs and reduces efficiency. Mr Mahindra expects to see new demand for production in Vietnam, Myanmar and possibly, if it can grasp the opportunity, India.

For some, the need to have more suppliers looks like an opportunity to promote possibilities at home. The government-owned Development Bank of Japan plans to subsidise relocation costs of companies that bring production facilities back to the country. Rich Lesser, the ceo of Boston Consulting Group (bcg), which advises big global firms, says that robotics and other new approaches to manufacturing make the case for moving factories closer to home more compelling, because they reduce the cost difference. Just as previous information technology was put to work underpinning the spread of supply chains, so today’s can be used to shorten them—potentially making companies more responsive to local tastes.

And the range of the changes information technology makes possible will only increase: that is the essence of the second current of post-covid acceleration. The growth of firms built on digital connections with and between hundreds of millions, or billions, of people, and which collect reams of cloud-based data in the process, was central to the bull market that met its end in February. That growth still has plenty of room to run.

Responding to covid-19 has seen many people and companies realise that it had more to offer them than they had realised. Zoom, an online videoconferencing service, was serving 10m customers a day at the beginning of the year, most of them in business meetings. Now it is providing 200m people a day ..... Slack, which provides a medium by which far-flung colleagues can co-ordinate things, has become part of dinner-table conversation. 

It is not only young tech-companies, and tech companies that were previously mostly used by the young, that have prospered. Microsoft’s Teams product is gaining many converts. No one expects the amount of distance working ever again to be as low as it was before the virus hit.

Restrictions put in place during the sars outbreak of 2003 helped accelerate China’s embrace of e-commerce. Covid-19 is having a similar effect, even in economies where e-commerce is already common. Chris Grigg, boss of British Land, one of Britain’s biggest retail and office landlords, says that as a result of covid-19 his company has brought forward by several years the time when it expects the share of shopping done online in Britain to double from its current 20%—already among the highest levels in the world. The pandemic may not just highlight the convenience of online life; it may also make some of its drawbacks less disturbing. Germans, who have historically well-founded privacy concerns, are resistant to anything that looks like “surveillance capitalism”. But Karl Haeusgen, chairman of hawe, a maker of hydraulic pumps, says an app that helped maintain public health by tracing covid-19 infections could make them less protective of their data. If that were the case, they might become converts to other data-driven business, too.

This trend will be good news for giants of the tech scene such as Alphabet, Amazon and Apple. So will other factors. The need for economic resilience will be added to the arguments against breaking up the biggest tech companies. If the tech world splinters into rival Chinese and Western camps each side will want its champions.

If things look pretty good for big tech, though, they look none too shabby for big everything else. As the world gets back on its feet, big firms will have better access to capital markets, giving them an extra edge over smaller competitors. And across the world there will be one increasingly big customer, too—the state. As Mr Mahindra says, “the only engine of consumption for the next 12 to 24 months will be government.” Big companies fit well with big government: they make its life simpler; they lobby it more assiduously.

These trends will inevitably have pernicious side-effects. Less dependence on China will mean less access to the rapid-fire innovation that takes place there. The bigger the tech firms, the harder it will be for startups to gain sufficient scale to challenge them. Not impossible; Zoom has done well in a world where bigger companies offer services along similar lines. But more difficult.

But though innovative businesses may face challenges in the post-covid world, they may also help bring it into being. This is not just because pharmaceutical and biotech companies are feverishly searching for drugs and vaccines. It is because business can knit people together. Mr Lesser of bcg argues that companies which build a bond with “emotionally vulnerable” consumers during the crisis may help reduce their anxieties on the other side—anxieties which might otherwise linger. Businesses will need to encourage people back to restaurants, bars and boutiques when lockdowns end but fears persist. And because small companies are being badly hit, recovery in these sectors will need to see new relationships formed.

Please provide your thoughts on how OPEN Source is able to IMPACT a Cure

Article #1: Open Source and Corona Article from zd.net

In Linux and open-source circles, we're fond of saying we've changed the world. And, well, we have changed the world. But, now, we, along with everyone else, face a new challenge: COVID-19.

Here are some of the open-source projects taking on the coronavirus.

CHIME: THE COVID-19 HOSPITAL IMPACT MODEL FOR EPIDEMICS

One of the biggest problems we face is how to plan and deal with the sheer number of patients that our hospitals will shortly have coming their way. This project, from the Predictive Healthcare team at Penn Medicine, is a tool that leverages SIR modeling, an epidemiological model, which computes the theoretical number of people infected with a contagious illness in a closed population over time, can help hospitals deal with capacity planning.

The newly open-sourced CHIME enables hospitals to enter information about their facility and population and then modify assumptions around COVID-19's spread and behavior. Once it has this information, hospital administrators can run a standard SIR model to project the number of new hospital admissions each day, along with the daily hospital census. They can also create best and worst-case scenarios to assist with capacity planning. 

The most important factor in this model is the doubling time. This defines how rapidly a disease spreads. Experiences in other geographical contexts suggest that doubling time may range from three to 13 days or more. You can enter your own doubling time estimate in an online version of CHIME and see what happens 

The US, according to Our World in Data, has a four-day doubling rate. That does not bode well for our future. Dr. Liz Specht estimated even at a doubling rate of six, "all hospital beds in the US will be filled by about May 10." But, at least with Chime, we can make what plans we can for dealing with this tsunami of cases. 

PFIZER OPEN-SOURCES SOFTWARE TOOLS

Pfizer is one of the Big Pharma drug giants. Historically, it and its rivals are as friendly to open source as Steve Ballmer was when he was Microsoft's CEO. Pfizer CEO Albert Bourla is now calling on all the drug companies to join forces to battle the pandemic. 

Bourla said:

"With very little known about this virus, many are working to develop cell-based assays, viral screening, serological assays, and translational models to test potential therapies and vaccines. Pfizer is committed to making the vital tools we develop available on an open source platform to the broader scientific community and to sharing the data and learnings gained with other companies in real time to rapidly advance therapies and vaccines to patients."

We don't have any further details at this time on this proposal. Still, just the fact that Pfizer is opening its code is significant. 

FACEBOOK OPEN-SOURCES COVID19 MEDICAL SUPPLIES

No, Facebook, isn't doing anything directly with open-source software and the virus. This is a Facebook group devoted to creating an open-source ventilator, and it has widened its reach to open-sourcing other medical supplies. Ventilators are essential for taking care of people struggling to breathe in serious cases of coronavirus. The US has approximately 100,000 ventilators, and we may need many more. Other groups, such as EndCoronavirus, are also working on open-source ventilators. 

Ventilators may look simple. They're not. Still, the need is great and, hopefully, something can be done in time to create a truly useful ventilator. If not, the efforts to open-source other medical aids won't go amiss. 

NEXTSTRAIN

This is an open-source program for the real-time tracking of pathogen evolution such as COVID-19. It's used to work out a disease's family history, which, in turn, can give us an idea of how it will turn out tomorrow. Previously, it had been used on Ebola; now, armed with coronavirus genetic data from Global Initiative on Sharing All Influenza Data (Gisaid), the project is tracking the coronavirus.

According to a Wired report, researchers using this software were able to establish that the virus was shared around Seattle as early as Jan. 20.  That was when people still thought there had to be a direct connection with a victim from Wuhan to be infected.

Only time will tell how useful any of these projects will turn out to be. That said, some of them may prove essential in the weeks and months ahead as we cope with the coronavirus.

Article #2 from Forbes

How Every PC Gamer In The World Can Join The Fight Against Coronavirus
Jason Evangelho I cover the fascinating worlds of Linux & consumer PC hardware.

Graphics cards are obviously a useful tool for gaming, video editing and even cryptocurrency mining. But did you know you can “donate” your AMD Radeon or Nvidia GPU’s spare compute cycles to researching and potentially fighting against the ongoing coronavirus pandemic?

Folding@Home is a distributed computing project that was founded in October 2000 at Stanford University, and it was specifically designed for disease research. It has historically been targeted at researching cancer, ALS, Parkinson’s, Huntington’s and more.

The software uses the spare CPU and GPU cycles of thousands of computers globally to simulate protein folding and computational drug design.

Put another way, Folding@Home uses computer simulations to understand a protein’s moving parts. Once scientists have a firm grasp on how the atoms move and interact within a protein, they can venture closer to discovering therapeutics to treat it.

But these simulations require massive computational power. And the Folding@Home team now wants to direct as much global compute power as possible at fighting SARS-CoV-2.

“Viruses also have proteins that they use to suppress our immune systems and reproduce themselves. To help tackle coronavirus, we want to understand how these viral proteins work and how we can design therapeutics to stop them.”

Greg Bowman, Folding@Home Director

The TL;DR

If you own a Windows, macOS or Linux PC that has a graphics card, you can join thousands of others around the world by donating your spare GPU cycles. This helps power the advanced simulations that could unlock a key to more deeply understanding the novel coronavirus (SARS-CoV-2) and its resulting disease COVID-19.

To get started, all you have to do is download the Folding@Home client for the OS you’re currently using. The linked page should automatically detect your OS and present the right installer.

After that, simply install Folding@Home. Should you need help, here’s a link to detailed installation guides for Windows, macOS and Linux.

Tips For Folding@Home

While this is meaningful software for a terrific cause, it isn’t the most elegant. So I’ll include a few tips for getting it up and running without grinding your PC to a halt.

1) Once the software is installed and launched, it should automatically open a web page that acts as a simple controller and monitor. If it doesn’t, point your browser at https://client.foldingathome.org.

2) If you have a GPU and you want to dedicate those compute cycles to various coranavirus research, choose “Any disease” from the dropdown box labeled “I support research fighting...”

When Folding@Home is active, it will put a heavy load on your system. This is normal. If you’d rather the software run only when you’re not using your PC, select “only when idle.” I’ve also found that a “Medium” power setting strikes a good balance between the app’s performance and system usability.

No GPU? Your CPU Is Still Useful

If you don’t have a dedicated graphics card, you can still make a difference. CPU-only workloads contribute to researching Alzheimer’s, Parkinson’s, Huntington’s and cancer. The Folding@Home team is also working on adding COVID-19 simulations to CPU workloads as well, but no timeline was given for that.
