How Cloud Computing Can Deal With Lightning Strikes and Hackers – Carnegie Endowment for International Peace

What exactly is the cloud and how does it work?

More and more of our daily lives takes place online, from banking and schooling to working and family gatherings, even more so amid the coronavirus pandemic. The cloud is the invisible computing architecture that keeps many of these digital platforms and tools running smoothly. Really, being in the cloud just means storing data on someone elses computer. A few major tech companies run massive global networks of data centers, linked with ocean-spanning fiber-optic cables and complex systems of integrated hardware and software. So there is no single cloud per se. Rather, companies like Amazon, Microsoft, and Google each run their own systems, almost like parallel internets. The risks of a companys whole cloud system going down at once are miniscule, though isolated outages of particular cloud services do happen.

Many internet users are seeing firsthand how disruptive it can be when the online tools they are relying on unexpectedly go offline or experience other bugs. For instance, when the videoconferencing software Zoom went offline for several hours one day in late August 2020, virtual classes around the United States were disrupted.

Dr. Tim Maurer is co-director of the Cyber Policy Initiative and a senior fellow at the Carnegie Endowment for International Peace. An expert on cybersecurity and geopolitics of the digital age, he currently focuses on the emerging global order for cybersecurity and the financial system.

Taking a step back, the pandemic has accelerated a decade-long transformation that was already under way. Many companies, governments, and ordinary people alike are switching from onsite information technology (IT) infrastructure to cloud computing, which provides data storage and processing services remotely. The good news is that many cloud companies have hired seasoned professional security teams with highly technical skills to protect the cloud infrastructure.

The bad news is that, as more and more people use and depend on the cloud, the risks and consequences of a systemic failure increase. Each of the major cloud providers have set up their systems to be as resilient as possible to any single-point failurethats why the risk of the whole cloud going down at once is exceedingly small. But that doesnt mean that it is immune to threatsthere are many ways that cloud services could be compromised or disrupted.

A few massive companies dominate the cloud computing market. These large cloud companies have the deep pockets and highly trained personnel needed to design and manage systems that are extremely secure and highly resilient to various risks of failure. That is why, as a rule, it is far more secure for most companies, organizations, and people to store their online data in the cloud rather than try to protect it themselves.

But theres a catch. Hackers and other nefarious criminals know that if they compromise a cloud provider, they can essentially scoop up the valuable data of many targets at once. This risk is called the Fort Knox dilemma: the data stores of cloud companies are highly protected but also highly prized targets. Theres a reason the Oceans Eleven cast targeted a casino instead of a convenience store.

Garrett Hinck was a research assistant with the Nuclear Policy Program at the Carnegie Endowment for International Peace.

And that isnt the only issue. The potential for threats against the cloud to create systemic risk are becoming increasingly apparent. A major cyber incident could have industry-wide or even economy-spanning effects, impacting financial services or triggering a temporary outage that prevents cloud clients from processing critical data like health insurance records.

Thankfully, the chances of an incident shutting down an entire cloud provider are exceedingly low: they make their systems as resilient as possible to keep that from happening. However, if one critical cloud-based dataset or process (like an algorithm for adjusting insurance claims, for example) failed, there could be significant consequences. Thats why its so important to understand the potential consequences of threats to cloud customers data as thoroughly as possible. As more and more critical data, like financial transactions and health records, are stored in the cloud, the consequences of major breaches will only increase.

The cloud is not invulnerable to hackers. While cloud providers can create secure environments, some vulnerabilities remain, and the security of the environment still also depends on their clients to store data securely. Cloud companies and the customers they serve both have important roles to play to keep data safe, and they divide up the responsibilities for data security accordingly. To use an analogy, it is not enough for a cloud provider to design a highly secure virtual safe: customers also have to be sure to set a good combination and keep that information from prying eyes.

In July 2019, for instance, a hacker broke into the cloud-based databases that stored personal information of Capital One credit card applicants and later attempted to sell the stolen information online. Personal information sold on the dark web can then be used by criminals for identity theft and other forms of fraud. This incident illustrates the damage that can ensue when security measures are breached.

Hackers arent the only risk facing the cloud or even the most common one. Cloud services can be disrupted by many unforeseen events including lightning strikes or flooding at data centers or even human error. In one notable incident, a typo by an Amazon engineer took the companys cloud storage service offline for many U.S.-based customers for four hours. These risks can have significant ripple effects because cloud services are complex and often rely on convoluted, interdependent internal systems. A failure can have outsize and unpredictable effects.

Additionally, vulnerabilities wired into the hardware and coded into the software that run the cloud can have broad impacts. The Meltdown and Spectre vulnerabilities, which affected the chips used in cloud servers, could have allowed attackers to spy on other cloud customers data. Cloud companies made herculean efforts to address these vulnerabilities and build a fix before the bugs became public in early 2018, underscoring their potential impact.

As organizations migrate to the cloud, responsibility for security becomes shared between cloud service providers and the organizations they serve. Having a clear understanding of who is responsible for what, especially where aspects of that responsibility are shared, is critical for pulling off a migration that leads to greater security, not less. Cloud service providers already assist their customers with facilitating this transition, and as they expand their business in the United States and abroad, it will be important that this assistance is scaled accordingly and provided equitably.

It is also clear that some reams of data are more important than others. The Health Insurance Portability and Accountability Act in the United States, for example, specifically protects medical data. Financial regulators focus on data and processes critical for the functioning of the financial system. It will become more important going forward for experts to open up the black box of cloud service providers and assess and protect risk based on how critical a particular set of data and associated services are. Finally, the tech industry remains a nascent sector. Unlike other sectors like aviation or finance, mechanisms to cooperate remain very limited among the main cloud service providers and competition even trumps shared security concerns.

How to approach IT logging in the cloud vs. on premises – TechTarget

Few things are more important for IT infrastructure than proper logging practices. Logs from both application and infrastructure components help IT admins find the root causes of issues. With the help of machine learning to analyze logs, IT admins can prevent and remediate security issues.

Logs are everywhere and new ones are generated all the time, but they cannot be taken for granted. As enterprises move into the cloud, they must understand how cloud operations change logging procedures. This article covers many aspects of logging in the cloud, including the cost of log collection, how to approach different types of cloud logs and storage decisions.

Logging on site is normally straightforward in terms of collection and analysis. While the cloud doesn't change that in theory, it does change a few considerations.

Log storage and analysis with on-premises resources traditionally isn't expensive. Large drives with multicore CPUs are reasonable in cost, and often last for years. With log storage and analysis in the cloud, users pay for resources they consume. While logs are not typically massive files, the volume of logs that accumulates when you collect them from many sources can add up rapidly. Consider whether you'll be throwing money away on the monthly charge to store them.

The real surprise admins get with logging in the cloud is how log files are processed. Compute resource use becomes another ongoing monthly cost -- unless an IT organization disposes of unnecessary files, their costs will add up quickly. A third-party service for log analysis can help with this particular cost -- and it can work with both cloud and on-premises logs. However, log analytics tools add their own cost and time investment, which organizations must keep in mind.

IT organizations must decide what to do with logs. Unlike with on-premises deployments, the IT organization does not control all of the infrastructure and components to run the application. The question is whether the organization has the ability to make changes in the cloud service. The answer depends on the service -- infrastructure (IaaS), platform (PaaS) or software (SaaS) -- as the access levels vary greatly.

With PaaS and IaaS cloud setups, IT admins have some control over logs and log analysis. With SaaS, the cloud provider controls almost everything from the data center hardware to the application. More admin control over the cloud environment makes it easier to see the value in log investment, because an organization can make meaningful changes, rather than just observing. The downside of more control over the cloud, with PaaS or IaaS, is the increased costs that go with it, which add to the cloud logging bill.

Pulling and processing detailed logs on a SaaS application might not be worth the investment in time and money, as an IT organization probably cannot make any effective changes to the SaaS environment or application. There's no real reason to work on these insights into information the cloud provider should already have.

With IaaS, cloud adopters have the most control over the environment, but are still limited to what the cloud provider allows them to adjust. Information from logs is key for cost-affecting decisions, such as whether to increase network bandwidth or compute resources for an application or service. Log analytics can lead to environment optimizations that pay off with lower overall cloud consumption.

When managing a cloud environment, select which logs to keep and which logs to ignore -- or not track at all. Look at the logs for the services that affect the environment and that are for aspects of the setup that you can change. Learn what the cloud provider monitors and optimizes as part of its responsibility for the environment.

To get started with logging in the cloud, look at the top 10 log types your organization monitors in its on-premises environment. Examples include access made between applications stacks, security logs or logs that show application errors. These logs should be universal -- from on premises to cloud services. Two additional logs that might not be on the on-premises log list are internet access and WAN. Connection to the cloud is key, so these logs should be a cornerstone of the collection process.

For logs the cloud provider would monitor, such as those tracking hardware events, verify the responsibility with the cloud provider. Commonly, the IaaS provider manages the hardware and therefore collects, analyzes and acts on hardware-related logs.

The length of time your organization retains its logs matters, especially for security events. After a security breach or attack occurs, logs are critical evidence used for a full investigation and to understand the effect of the issue.

Since cloud storage is a monthly cost, determine what logs to keep long term and which ones to dismiss on a more frequent basis. Consider transferring some types of cloud logs into long-term archival storage for future reference. Retrieval time can take hours or even days -- but this history could save a lot in costs when you need it.

While cloud-based log collection, management and analysis follow many of the same guidelines as these activities in on-premises environments, your organization will be most efficient if it accounts for cloud-related differences. Pay attention to log retention times, the size of your log storage and how many logs you're processing to keep costs under control. With logging in the cloud, key events and actions should be similar to those used in on-premises procedures, but don't forget to include WAN and internet activity logs, as these are more unique to cloud environments.

Are We Close To Realising A Quantum Computer? Yes And No, Quantum Style – Swarajya

Scientists have been hard at work to get a new kind of computer going for about a couple of decades. This new variety is not a simple upgrade over what you and I use every day. It is different. They call it a quantum computer.

The name doesnt leave much to the imagination. It is a machine based on the central tenets of the most successful theory of physics yet devised quantum mechanics. And since it is based on such a powerful theory, it promises to be so advanced that a conventional computer, the one we know and recognise, cannot keep up with it.

Think of the complex real-world problems that are hard to solve and its likely that quantum computers will throw up answers to them someday. Examples include simulating complex molecules to design new materials, making better forecasts for weather, earthquakes or volcanoes, map out the reaches of the universe, and, yes, demystify quantum mechanics itself.

One of the major goals of quantum computers is to simulate a quantum system. It is probably the reason why quantum computation is becoming a major reality, says Dr Arindam Ghosh, professor at the Department of Physics, Indian Institute of Science.

Given that the quantum computer is full of promise, and work on it has been underway for decades, its fair to ask do we have one yet?

This is a million-dollar question, and there is no simple answer to it, says Dr Rajamani Vijayaraghavan, the head of the Quantum Measurement and Control Laboratory at the Tata Institute of Fundamental Research (TIFR). Depending on how you view it, we already have a quantum computer, or we will have one in the future if the aim is to have one that is practical or commercial in nature.

We have it and dont. That sounds about quantum.

In the United States, Google has been setting new benchmarks in quantum computing.

Last year, in October, it declared quantum supremacy a demonstration of a quantum computers superiority over its classical counterpart. Googles Sycamore processor took 200 seconds to make a calculation that, the company claims, would have taken 10,000 years on the worlds most powerful supercomputer.

This accomplishment came with conditions attached. IBM, whose supercomputer Summit (the worlds fastest) came second-best to Sycamore, contested the 10,000-year claim and said that the calculation would have instead taken two and a half days with a tweak to how the supercomputer approached the task.

Some experts suggested that the nature of the task, generating random numbers in a quantum way, was not particularly suited to the classical machine. Besides, Googles quantum processor didnt dabble in a real-world application.

Yet, Google was on to something. For even the harsh critic, it provided a glimpse of the spectacular processing power of a quantum computer and whats possible down the road.

Google did one better recently. They simulated a chemical reaction on their quantum computer the rearrangement of hydrogen atoms around nitrogen atoms in a diazene molecule (nitrogen hydride or N2H2).

The reaction was a simple one, but it opened the doors to simulating more complex molecules in the future an eager expectation from a quantum computer.

But how do we get there? That would require scaling up the system. More precisely, the number of qubits in the machine would have to increase.

Short for quantum bits, qubits are the basic building blocks of quantum computers. They are equivalent to the classical binary bits, zero and one, but with an important difference. While the classical bits can assume states of zero or one, quantum bits can accommodate both zero and one at the same time a principle in quantum mechanics called superposition.

Similarly, quantum bits can be entangled. That is when two qubits in superposition are bound in such a way that one dictates the state of the other. It is what Albert Einstein in his lifetime described, and dismissed, as spooky action at a distance.

Qubits in these counterintuitive states are what allow a quantum computer to work its magic.

Presently, the most qubits, 72, are found on a Google device. The Sycamore processor, the Google chip behind the simulation of a chemical reaction, has a 53-qubit configuration. IBM has 53 qubits too, and Intel has 49. Some of the academic labs working with quantum computing technology, such as the one at Harvard, have about 40-50 qubits. In China, researchers say they are on course to develop a 60-qubit quantum computing system within this year.

The grouping is evident. The convergence is, more or less, around 50-60 qubits. That puts us in an interesting place. About 50 qubits can be considered the breakeven point the one where the classical computer struggles to keep up with its quantum counterpart, says Dr Vijayaraghavan.

It is generally acknowledged that once qubits rise to about 100, the classical computer gets left behind entirely. That stage is not far away. According to Dr Ghosh of IISc, the rate of qubit increase is today faster than the development of electronics in the early days.

Over the next couple of years, we can get to 100-200 qubits, Dr Vijayaraghavan says.

A few more years later, we could possibly reach 300 qubits. For a perspective on how high that is, this is what Harvard Quantum Initiative co-director Mikhail Lukin has said about such a machine: If you had a system of 300 qubits, you could store and process more bits of information than the number of particles in the universe.

In Indian labs, we are working with much fewer qubits. There is some catching up to do. Typically, India is slow to get off the blocks to pursue frontier research. But the good news is that over the years, the pace is picking up, especially in the quantum area.

At TIFR, researchers have developed a unique three-qubit trimon quantum processor. Three qubits might seem small in comparison to examples cited earlier, but together they pack a punch. We have shown that for certain types of algorithms, our three-qubit processor does better than the IBM machine. It turns out that some gate operations are more efficient on our system than the IBM one, says Dr Vijayaraghavan.

The special ingredient of the trimon processor is three well-connected qubits rather than three individual qubits a subtle but important difference.

Dr Vijayaraghavan plans to build more of these trimon quantum processors going forward, hoping that the advantages of a single trimon system spill over on to the larger machines.

TIFR is simultaneously developing a conventional seven-qubit transmon (as opposed to trimon) system. It is expected to be ready in about one and a half years.

About a thousand kilometres south, at IISc, two labs under the Department of Instrumentation and Applied Physics are developing quantum processors too, with allied research underway in the Departments of Computer Science and Automation, and Physics, as well as the Centre for Nano Science and Engineering.

IISc plans to develop an eight-qubit superconducting processor within three years.

Once we have the know-how to build a working eight-qubit processor, scaling it up to tens of qubits in the future is easier, as it is then a matter of engineering progression, says Dr Ghosh, who is associated with the Quantum Materials and Devices Group at IISc.

It is not hard to imagine India catching up with the more advanced players in the quantum field this decade. The key is to not think of India building the biggest or the best machine it is not necessary that they have the most number of qubits. Little scientific breakthroughs that have the power to move the quantum dial decisively forward can come from any lab in India.

Zooming out to a global point of view, the trajectory of quantum computing is hazy beyond a few years. We have been talking about qubits in the hundreds, but, to have commercial relevance, a quantum computer needs to have lakhs of qubits in its armoury. That is the challenge, and a mighty big one.

It isnt even the case that simply piling up qubits will do the job. As the number of qubits go up in a system, it needs to be ensured that they are stable, highly connected, and error-free. This is because qubits cannot hang on to their quantum states in the event of environmental noise such as heat or stray atoms or molecules. In fact, that is the reason quantum computers are operated at temperatures in the range of a few millikelvin to a kelvin. The slightest disturbance can knock the qubits off their quantum states of superposition and entanglement, leaving them to operate as classical bits.

If you are trying to simulate a quantum system, thats no good.

For that reason, even if the qubits are few, quantum computation can work well if the qubits are highly connected and error-free.

Companies like Honeywell and IBM are, therefore, looking beyond the number of qubits and instead eyeing a parameter called quantum volume.

Honeywell claimed earlier this year that they had the worlds highest performing quantum computer on the basis of quantum volume, even though it had just six qubits.

Dr Ghosh says quantum volume is indeed an important metric. Number of qubits alone is not the benchmark. You do need enough of them to do meaningful computation, but you need to look at quantum volume, which measures the length and complexity of quantum circuits. The higher the quantum volume, the higher is the potential for solving real-world problems.

It comes down to error correction. Dr Vijayaraghavan says none of the big quantum machines in the US today use error-correction technology. If that can be demonstrated over the next five years, it would count as a real breakthrough, he says.

Guarding the system against faults or "errors" is the focus of researchers now as they look to scale up the qubits in a system. Developing a system with hundreds of thousands of qubits without correcting for errors cancels the benefits of a quantum computer.

As is the case with any research in the frontier areas, progress will have to accompany scientific breakthroughs across several different fields, from software to physics to materials science and engineering.

In light of that, collaboration between academia and industry is going to play a major role going forward. Depending on each of their strengths, academic labs can focus on supplying the core expertise necessary to get a quantum computer going while the industry can provide the engineering muscle to build the intricate stuff. Both are important parts of the quantum computing puzzle. At the end of the day, the quantum part of a quantum computer is tiny. Most of the machine is high-end electronics. The industry can support that.

It is useful to recall at this point that even our conventional computers took decades to develop, starting from the first transistor in 1947 to the first microprocessor in 1971. The computers that we use today would be unrecognisable to people in the 1970s. In the same way, how quantum computing in the future, say, 20 years down the line, is unknown to us today.

However, governments around the world, including India, are putting their weight behind the development of quantum technology. It is clear to see why. Hopefully, this decade can be the springboard that launches quantum computing higher than ever before. All signs point to it.

Spin-Based Quantum Computing Breakthrough: Physicists Achieve Tunable Spin Wave Excitation – SciTechDaily

Magnon excitation. Credit: Daria Sokol/MIPT Press Office

Physicists from MIPT and the Russian Quantum Center, joined by colleagues from Saratov State University and Michigan Technological University, have demonstrated new methods forcontrolling spin waves in nanostructured bismuth iron garnet films via short laser pulses. Presented inNano Letters, the solution has potential for applications in energy-efficient information transfer and spin-based quantum computing.

Aparticles spin is its intrinsic angular momentum, which always has a direction. Inmagnetized materials, the spins all point in one direction. A local disruption of this magnetic order is accompanied by the propagation of spin waves, whose quanta are known as magnons.

Unlike the electrical current, spin wave propagation does not involve a transfer of matter. Asaresult, using magnons rather than electrons to transmit information leads to much smaller thermal losses. Data can be encoded in the phase or amplitude of a spin wave and processed via wave interference or nonlinear effects.

Simple logical components based on magnons are already available as sample devices. However, one of the challenges of implementing this new technology is the need to control certain spin wave parameters. Inmany regards, exciting magnons optically is more convenient than by other means, with one of the advantages presented in the recent paper in Nano Letters.

The researchers excited spin waves in a nanostructured bismuth iron garnet. Even without nanopatterning, that material has unique optomagnetic properties. It is characterized by low magnetic attenuation, allowing magnons topropagate over large distances even at room temperature. It is also highly optically transparent in the near infrared range and has a high Verdet constant.

The film used in the study had an elaborate structure: a smooth lower layer with a one-dimensional grating formed on top, with a 450-nanometer period (fig.1). This geometry enables the excitation ofmagnons with a very specific spin distribution, which is not possible for an unmodified film.

To excite magnetization precession, the team used linearly polarized pump laser pulses, whose characteristics affected spin dynamics and the type of spin waves generated. Importantly, wave excitation resulted from optomagnetic rather than thermal effects.

Schematic representation of spin wave excitation by optical pulses. The laser pump pulse generates magnons by locally disrupting the ordering of spins shown as violet arrows in bismuth iron garnet (BiIG). A probe pulse is then used to recover information about the excited magnons. GGG denotes gadolinium gallium garnet, which serves as the substrate. Credit: Alexander Chernov et al./Nano Letters

The researchers relied on 250-femtosecond probe pulses to track the state of the sample and extract spin wave characteristics. Aprobe pulse can be directed to any point on the sample with adesired delay relative to the pump pulse. This yields information about the magnetization dynamics in a given point, which can be processed to determine the spin waves spectral frequency, type, and other parameters.

Unlike the previously available methods, the new approach enables controlling the generated wave by varying several parameters of the laser pulse that excites it. In addition to that, thegeometry of the nanostructured film allows the excitation center to be localized inaspot about 10 nanometers in size. The nanopattern also makes it possible to generate multiple distinct types of spin waves. The angle of incidence, the wavelength and polarization of the laser pulses enable the resonant excitation of the waveguide modes of the sample, which are determined by the nanostructure characteristics, so the type of spin waves excited can be controlled. It is possible for each of the characteristics associated with optical excitation to be varied independently to produce the desired effect.

Nanophotonics opens up new possibilities in the area of ultrafast magnetism, said the studys co-author, Alexander Chernov, who heads the Magnetic Heterostructures and Spintronics Lab at MIPT. The creation of practical applications will depend on being able to go beyond the submicrometer scale, increasing operation speed and the capacity for multitasking. We have shown a way to overcome these limitations by nanostructuring a magnetic material. We have successfully localized light in a spot few tens of nanometers across and effectively excited standing spin waves of various orders. This type of spin waves enables the devices operating at high frequencies, up to the terahertz range.

The paper experimentally demonstrates an improved launch efficiency and ability to control spin dynamics under optical excitation by short laser pulses in a specially designed nanopatterned film of bismuth iron garnet. It opens up new prospects for magnetic data processing and quantum computing based on coherent spin oscillations.

Cuomo Threat Against Trump Applies to All Who Support President’s Agenda – AmmoLand Shooting Sports News

Cuban dictator Fidel Armas para qu? Castro provides an appropriate backdrop for New York's gun-grabbing wannabe totalitarian. (Governor Andrew Cuomo/Facebook)

U.S.A. -( better have an army if he thinks hes gonna walk down the street in New York, the New York Post quoted Gov. Andrew Cuomo in a Sept. 3 article. The governor was reacting to the president saying he was considering pulling federal funds from cities that encourage lawlessness by using threats that do just that.

New Yorkers dont want to have anything to do with him, Cuomo asserted. He cant have enough bodyguards to walk through New York City, people dont want to have anything to do with him.

That sure sounds like a death threat. If youre skeptical of that, feel free to send similar sentiments to Joe Biden about your town, and see if that doesnt result in a Secret Service response.

Its also a telling admission that New Yorks draconian gun laws must not work, but as history teaches us, thats not why those bent on political supremacy really impose them. And its more than that. Its a warning to all Trump supporters that they can expect the same hostility directed at them by New York Democrats and by those they encourage or incite to violence.

Thats because, in a very real way, Trump is an avatar, making fair the question How is it possible to hate a man like this and not hate those he represents? Those who voted for him didnt so much do it because they like the man it's because what he pledged in his campaign resonated with their values, and with the direction they want to see the country move in.

The Left Has One More ArgumentKill Them! a column by conservative commentator Ann Coulter noted:

What were seeing is the following: Prominent liberals repeatedly tell us, with deadly seriousness, that Trump and his supporters are: Hitler, fascists, bigots, haters, racists, terrorists, criminals and white supremacists, which is then followed by liberals physically attacking conservatives.

Its not just prominent liberals. Prominent useful idiot Republican for Biden Rick Wilson told MSNBCs openly socialist Lawrence ODonnell:

[H]e's a guy backed in large measure by a group of white supremacists and neo-nazis

Not all Trump supporters are Nazis, Wilson tweeted, seemingly conceding that point, but not quite. All Nazis are Trump supporters, he followed up, showing he intended the lying smear to tar all. And not to wander too far afield, but Hitlers National Socialism was based on Marx and dont let lying socialists tell you otherwise.

We're living in a time when Antifa/BLM street thugs are accosting people simply trying to mind their own business and screaming demands that they raise their fists in solidarity with communism. It is now considered acceptable in progressive circles to parrot the narrative lie that Silence is violence (thereby justifying self-defense). Such deliberate mob-inciting rhetoric from Democrat politicians like Cuomo needs to be seen for what it is: Political extortion to chill public support for Republicans. Its morally no different than radical leftists threatening to (further) dox people they hate for attending a Self Defense is Not a Crime rally in support of Kyle Rittenhouse.

Its no surprise that we see low-hanging fruit inspired to action, as the recent murder of Patriot Prayer member Aaron Jay Danielson proves. Nor should we be surprised when we see academics further stoke the flames, like the University of Rhode Island Professor Erik Loomis, a man who incidentally feeds off tax plunder at a public trough.

He killed a fascist. I see nothing wrong with it, at least from a moral perspective, Loomis wrote on his blog concerning that murder. Essentially, if you disagree, hes saying you deserve a death penalty.

How do you think such lunatics react when they see billionaire Michael Bloombergs Everytown spreading lies about those who believe the right of the people to keep and bear arms shall not be infringed like:


Does anyone really still believe that the reason behind the citizen disarmament wish list a Biden/Harris administration threatens to impose is about commonsense gun safety?

About David Codrea:

David Codrea is the winner of multiple journalist awards for investigating/defending the RKBA and a long-time gun owner rights advocate who defiantly challenges the folly of citizen disarmament.

Deep Dive: What would it take to change UNCW’s mind? [Free] – Port City Daily

Editors note: Haley, a UNCW student interviewed for this article, asked that only her first name be used because she fears stigmatization due to her positive Covid-19 test.

WILMINGTON Haley drove to Raleigh in mid-July to see her mother, who was hospitalized in an intensive care unit with an illness unrelated to the coronavirus. She followed the hospitals safety guidelines, and other than that trip, she said her only excursions in the prior days had been a one-time grocery run and work shifts at a veterinary clinic.

Three days after visiting her mother, Haley woke up with a fever, then suffered from chills and intense chest pain in the following days. She called the campus health clinic at UNCW, where she is a student, and told them she needed a Covid-19 test.

Eight days after Haley was tested, a doctor called to inform her she was Covid-19 positive. The doctor believed she got the virus while visiting her mother in Raleigh, but contact tracers thought it was more likely she was exposed in New Hanover County, Haley said.

I was feeling a lot of guilt. I was freaking out thinking that I had infected so many people, Haley said. Thats the part that has been really scary, is I thought I was doing everything right but still ended up with it.

Haley was diagnosed in late July, when UNCW had only a handful of positive cases on its radar. Since July, UNCW has reported 323 positive cases among students, and 10 cases among faculty and staff; most are recent, with 273 student cases and 7 faculty cases still active.

In the past month, three N.C. universities East Carolina University, UNC-Chapel Hill, and N.C. State University have bailed on in-person instruction for at least the foreseeable future, converting to an online-only class structure. Despite persistent criticism from the student body, and apparently being on the same track for increasing Covid-19 cases, UNCW currently has no official plans to make a similar decision.

In the week leading up to UNC-CHs campus closure decision on Aug. 17, UNC-CH reported 166 new cases; in the week of Aug. 31-Sept. 7, UNCW reported 158 new cases (and then over 50 more since then). UNC-CH had reported four clusters of concentrated cases at the time of its announcement. To date, UNCW has reported six clusters.

UNCW began classes on Aug. 19, nine days later than Chapel Hill, and its undergraduate population is at around 14,650 students, which clocks in at around 76 percent of Chapel Hills undergraduate population.

Haleys work shift at the veterinary clinic last weekend ended late in the night, and on the way back to her off-campus house, she saw a bunch of wicked young college kids, just all parking their cars along the streets, making their way into house parties outside the boundaries of campus, she said.

I feel like a lot of people dont know how easily you can get it, because I thought I was doing everything right, and then I still got it, Haley said. Im very worried for all of the students who are on campus right now, because I dont feel like they are going to be as efficient and proactive in trying to make sure that theyre not getting this virus.

Next week, the university will mandate the wearing of masks in all public spaces, said Chancellor Jose Sartarelli on a Zoom call with faculty.

Throughout the summer, UNCW officials were communicating with leaders at the New Hanover County Health Department, as both entities hoped that a collaborative relationship would strengthen their ability to slow the spread of the virus. Their relationship was bolstered on Aug. 7 by an agreement that allows for the exchange of patient information between the university and health department. The agreement fortified local contact tracing programs by increasing the resources, specifically the names of Covid-positive individuals, made available to the health department, which spearheads such efforts.

Carla Turner, assistant health director for New Hanover County, said conversations between the health department and UNCW officials have increased in frequency and now occur daily.

We were keeping an eye on the increasing number of 18-to-24 year old positives in New Hanover County, Turner said. As we watched that number continue to rise, and through our case investigation and contact tracing determined that there was some social gathering happening amongst students in the community, we reached out to UNCW.

Turner said during a Labor Day weekend phone call between the two entities, UNCW presented its now-underway plan to have double-occupancy rooms on campus converted into singles, Turner called the plan a really good first step to try to separate some of the contacts that were seeing amongst students.

Although the county and university are swapping case information and patient data, contact tracers still dont have a crystal-clear method of pegging a Covid-positive individual as a UNCW student.

The only way we are going to know that is when we call and talk to them and they tell us that they are, Turner said. What were doing is not punitive. We are just trying to protect this community as a whole.

The information contact tracers receive is only as good as the Covid-positive individual is willing to provide, Turner said.

One of the speed bumps were running into is that folks that were calling arent being completely forthcoming with information, she said.

One month ago, the 18-to-24-year-old demographic accounted for 26% of Covid-19 cases in New Hanover County, Turner said. As of last week, the 18-to-24-year-old population accounts for 34% percent of positive cases in the county.

In that age range of 18-to-24, we are seeing a steady increase of positives, as we see a slow decrease in the 25-to-49-year-old age range, Turner said.

On the morning of Sept. 10, James Winebrake, UNCWs provost and vice chancellor for academic affairs, sent out a mass email to university faculty.

He acknowledged the de-densification protocols implemented earlier in the week having first-year students in double rooms make the difficult decision of figuring out who gets to stay and who has to leave the dorm increases the complexities that faculty are facing in their courses due to student absenteeism related to COVID, Winebrake said in the email.

There is, of course, another option and that is an administrative directive to move ALL classes online However, I believe strongly in the principle that faculty are in the best position to determine how to deliver their course content, and I am not advocating for an administrative directive to move all classes online at this time. he wrote.

From his computer webcam, Chancellor Jose Sartarelli addressed UNCW faculty earlier this week in a Zoom meeting of the faculty senate, the legislative body of university professors.

The past few days have been more stable but we had heard from our folks at the local health authority, and they were getting concerned by the fact that our numbers are going up and the numbers for the county are going down, Sartarelli said. And so we discussed it and we came to the conclusion that perhaps another step in our effort would be to de-densify somewhat, somewhat more than we had been doing before. A lot of the positives that we had been getting were from the dorms next to the student village.

According to internal emails, after a UNCW press release mentioned the health department in relation to the de-densification decision, blame and questions were directed toward county health officials. New Hanover County communications staff told UNCW comms staff that in future press releases, if the health department was going to be cited, the county would like prior notice.

We would definitely like to be informed and allowed to provide edits on communications that mention the health department directly, Chief Communications Officer Jessica Loeper wrote to a UNCW media relations official.

[Editors note: UNCW is currently operating with an interim chief communications officer after CCO Janine Iamunno went on medical leave in early July]

On Aug. 28, Philip Tarte, the countys health director, forwarded a UNCW coronavirus-related press release to the departments preparedness coordinator, Lisa Brown.

I was not aware of the dashboard that is linked in the release, Brown responded, referring to UNCWs public data dashboard that represents confirmed COVID cases among UNCW students, faculty, and staff.

In reviewing the data in the public-facing reported cases, I am concerned about the timeliness of reporting these cases to NHC as that is not matching up with what I see in our cases, Brown wrote.

Two health department staffers from the county were placed at UNCW student health recently, to further integrate and fortify the joint-contact tracing apparatus, Turner said.

Dr. Katrin Wesner-Harts, UNCWs interim associate vice chancellor for student affairs, said she is grateful for the countys assistance as UNCW navigates through its decision-making process.

People have been dealing with this for months now and we all need to sort of stay with it, and not give up because thats going to play an important part, Wesner-Harts said.

Back on the Zoom call, Sartarelli talked about new mitigation efforts currently in the works.

Once this is done, next week were going to be talking to them, all of them, and demanding a little more stuff, the chancellor said. And the stuff that were going to be demanding is the wearing of masks everywhere, and even when youre sitting outside with your friends.

After Sartarelli finished his update, Provost James Winebrake took over, empathizing with professors on how uprooting a significant number of on-campus students could affect the facultys ability to teach.

This is going to be challenging. We cant kid ourselves. Theres going to be possibly a few hundred mostly freshmen who will be leaving campus, he said.

Professor Aaron Wilcox chimed in. I just want to stress again, the difference between a temporary pivot for faculty to provide online instruction materials, and to effectively have to teach an entire second course for the entire remainder of the semester, he said. That is a giant ask, and I understand their need for de-densification, but thats a lot to put on the faculty.

Winebrake responded: There arent a lot of easy answers here, but were doing what we think we have to do, and in consultation with the county health officials, what we need to do.

To inform a potential decision on canceling in-person classes, UNCW is following a seven-point plan of different metrics access to supplies such as personal protective equipment; adequate staffing; input from county partners; adequate access to testing; the number of active positive cases; adequate isolation/quarantine space; and guidance from different state authorities.

In the past two weeks, according to the UNCW dashboard, 280 active cases were reported in the community. Since July, 333 total cases have been reported.

When asked about the pivot plan, and what the specific number of active positive cases is that would warrant a campus closure, a UNCW spokesperson said, A variety of these factors will help inform the decision when to pivot from in-person to online, if needed. As the pivot plan was being developed, we consulted with the New Hanover CountyPublic Health Department.

When asked if New Hanover County public health officials have confidence in UNCWs ability to continue this semester as-planned, without needing to transition to an online-only format, a New Hanover County spokesperson said, Public Health is hopeful that UNCWs decision to move students to single rooms will help slow the spread of the virus by decreasing density and the close-proximity of student living.

The county spokesperson added that UNCW has never been asked by the county to make a transition away from in-person classes.

Public Healths consultation has involved, and continues to include, helping UNCW develop a plan that was flexible, including mitigation options, based on data and trends.Any actions by UNCW are part of their options in their plan, she said.

Provost Winebrake sent an emailed statement when asked about how UNCW officials are quantifying the risk assumed by the university as it continues operations. Each campus is different, and certain strategies may work well on one campus but not on another. Thanks to great work by our faculty and staff, and great effort by the vast majority of our students, UNCW is responding to conditions caused by the pandemic as efficiently and effectively as possible, the statement said.

We certainly understand that this virus spreads rapidly and that the situation on our campus could evolve quickly. We are approaching each day with a flexible mindset, and we are prepared to alter our plans as needed to continue supporting our educational mission in conjunction with the health and safety of our students, faculty, staff and the community.

Haley, the UNCW student who tested positive for Covid-19 in July, said the unexpectedness of her diagnosis makes her wary of UNCWs ability to continue operations on its current path.

As far as what goes on on-campus, I dont know, but its the stuff that goes on off-campus that is obviously concerning, she said. Theres just so many unknowns that we dont know about this virus, that I dont think its safe to have students congregating in classrooms. I just really dont think thats a good idea.
