Self-repairing software tackles malware

     University of Utah computer scientists have developed software that not only detects and eradicates never-before-seen viruses and other malware, but also automatically repairs damage caused by them. The software then prevents the invader from ever infecting the computer
again.
     A3 is a software suite that works with a virtual machine - a virtual computer that emulates the operations of a computer without dedicated hardware. The A3 software is designed to watch over the virtual machines operating system and applications, says Eric Eide, University of Utah research assistant professor of computer science leading the university s A3 team with U computer science associate professor John Regehr. A3 is designed to protect servers or similar business-grade computers that run on the Linux operating system. It also has been demonstrated to protect military applications.
     The new software called A3, or Advanced Adaptive Applications, was co-developed by Massachusetts-based defense contractor, Raytheon BBN. The four-year project was completed in late September.
     There are no plans to adapt A3 for home computers or laptops, but Eide says this could be possible in the future.
     "A3 technologies could find their way into consumer products someday, which would help consumer devices protect themselves against fast-spreading malware or internal corruption of software components. But we havent tried those experiments yet," he says.
     Unlike a normal virus scanner on consumer PCs that compares a catalog of known viruses to something that has infected the computer, A3 can detect new, unknown viruses or malware automatically by sensing that something is occurring in the computer s operation that is not correct. It then can stop the virus, approximate a repair for the damaged software code, and then learn to never let that bug enter the machine gain.
     While the military has an interest in A3 to enhance cybersecurity for its mission-critical systems, A3 also potentially could be used in the consumer space, such as in web services like Amazon. If a virus or attack stops the service, A3 could repair it in minutes without having to take the servers down.

The Right to a “Custody Hearing” under International Law

by Maria Laura Canineu
February 3, 2014

        A person who is arrested has a right to be brought promptly before a judge. This is a longstanding and fundamental principle of international law, crucial for ensuring that the person’s arrest, treatment, and any ongoing detention are lawful.
        Yet, until now, Brazil has not respected this right. Detainees often go months before seeing a judge. For instance, in São Paulo state, which houses 37 percent of Brazil’s total prison population, most detainees are not brought before a judge for at least three months. The risk of ill-treatment is often highest during the initial stages of detention, when police are questioning a suspect. The delay makes detainees more vulnerable to torture and other serious forms of mistreatment by abusive police officers.
        In 2012, the UN Subcommittee on Prevention of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment reported that it had received “repeated and consistent accounts of torture and ill-treatment” in São Paulo and other Brazilian states, “committed by, in particular, the military and civil police.” The torture had allegedly occurred in police custody or at the moment of arrest, on the street, inside private homes, or in hidden outdoor areas, and was described as “gratuitous violence, as a form of punishment, to extract confessions, and as a means of extortion.”
        In addition to violating the rights of detainees, these abusive practices make it more difficult for the police to establish the kind of public trust that is often crucial for effective crime control. These practices undermine legitimate efforts to promote public security and curb violent crime, and thus have a negative impact on Brazilian society as a whole.
        The right to be brought before a judge without unnecessary delay is enshrined in treaties long ago ratified by Brazil, including the International Covenant on Civil and Political Rights (ICCPR) and the American Convention on Human Rights. The United Nations Human Rights Committee, which is responsible for interpreting the ICCPR, has determined that the delay between the arrest of an accused and the time before he is brought before a judicial authority “should not exceed a few days,” even during states of emergency.
        Other countries in Latin America have incorporated this right into their domestic law. For instance, in Argentina, the federal Criminal Procedure Code requires that in cases of arrest without a judicial order, the detainee must be brought to a competent judicial authority within six hours.
        In contrast, Brazil’s criminal procedure code requires that when an adult is arrested in flagrante and held in police custody, only the police files of the case need to be presented to the judge within 24 hours, not the actual detainee. Judges evaluate the legality of the arrest and make the decision about whether to order continued detention or other precautionary measures based solely on the written documents provided by the police.
        The code establishes a maximum of 60 days for the first judicial hearing with the detainee, but does not explicitly say when this period begins. In practice, this often means that police in Brazil can keep people detained, with formal judicial authorization, for several months, without giving the detainee a chance to actually see a judge.
        According to the code, the only circumstance in which police need to bring a person before the judge immediately applies to cases of crimes not subject to bail in which arresting officer was not able to exhibit the arrest order to the person arrested at the time of arrest. Otherwise, the detainee may also not see a judge for several months.

Innovation is the new key to survival

[…]

At its most basic, innovation presents an optimal strategy for controlling costs. Companies that have invested in such technologies as remote mining, autonomous equipment and driverless trucks and trains have reduced expenses by orders of magnitude, while simultaneously driving up productivity.

Yet, gazing towards the horizon, it is rapidly becoming clear that innovation can do much more than reduce capital intensity. Approached strategically, it also has the power to reduce people and energy intensity, while increasing mining intensity.

Capturing the learnings 

The key is to think of innovation as much more than research and development (R&D) around particular processes or technologies. Companies can, in fact, innovate in multiple ways, such as leveraging supplier knowledge around specific operational challenges, redefining their participation in the energy value chain or finding new ways to engage and partner with major stakeholders and constituencies.

To reap these rewards, however, mining companies must overcome their traditionally conservative tendencies. In many cases, miners struggle to adopt technologies proven to work at other mining companies, let alone those from other industries. As a result, innovation becomes less of a technology problem and more of an adoption problem.

By breaking this mindset, mining companies can free themselves to adapt practical applications that already exist in other industries and apply them to fit their current needs. For instance, the tunnel boring machines used by civil engineers to excavate the Chunnel can vastly reduce miners" reliance on explosives. Until recently, those machines were too large to apply in a mining setting. Some innovators, however, are now incorporating the underlying technology to build smaller machines—effectively adapting mature solutions from other industries to realize more rapid results. 

Re-imagining the future

At the same time, innovation mandates companies to think in entirely new ways. Traditionally, for instance, miners have focused on extracting higher grades and achieving faster throughput by optimizing the pit, schedule, product mix and logistics. A truly innovative mindset, however, will see them adopt an entirely new design paradigm that leverages new information, mining and energy technologies to maximize value. […]

Approached in this way, innovation can drive more than cost reduction. It can help mining companies mitigate and manage risks, strengthen business models and foster more effective community and government relations. It can help mining services companies enhance their value to the industry by developing new products and services. Longer-term, it can even position organizations to move the needle on such endemic issues as corporate social responsibility, environmental performance and sustainability.

A deep freeze this week in the Lone Star state, which relies on electricity to heat many homes, is causing power demand to skyrocket. At the same time, natural gas, coal, wind and nuclear facilities in Texas have been knocked offline by the unthinkably low temperatures.

“The extreme cold is causing the entire system to freeze up,” said Jason Bordoff, director of Columbia University’s Center on Global Energy Policy. “All sources of energy are underperforming in the extreme cold because they’re not designed to handle these unusual conditions.”

The ripple effects are being felt around the nation as Texas’ prolific oil-and-gas industry stumbles.

It’s striking that these power outages are happening in a state with abundant energy resources. Texas produces more electricity than any other US state — generating almost twice as much as Florida, the next-closest, according to federal statistics.

Wind power is also booming in Texas, which produced about 28% of all the US wind-powered electricity in 2019, the EIA said. But the problem is that not only is Texas an energy superpower, it tends to be an above-average temperature state. That means its infrastructure is ill-prepared for the cold spell currently wreaking havoc. And the consequences are being felt by millions.

Critics of renewable energy have pointed out that wind turbines have frozen or needed to be shut down due to the extreme weather.

Even though other places with colder weather (like Iowa and Denmark) rely on wind for even larger shares of power, experts said the turbines in Texas were not winterized for the unexpected freeze.

But this is not just about wind turbines going down. Natural gas and coal-fired power plants need water to stay online. Yet those water facilities froze in the cold temperatures and others lost access to the electricity they require to operate.

It’s too early to definitively say what went wrong in Texas and how to prevent similar outages. More information will need to be released by state authorities. Still, some experts say the criticism of wind power appears overdone already. “In terms of the blame game, the focus on wind is a red herring. It’s more of a political issue than what is causing the power problems on the grid,” said Dan Cohan, associate professor of environmental engineering at Rice University.

The energy crisis in Texas raises also questions about the nature of the state’s deregulated and decentralized electric grid. Unlike other states, Texas has made a conscious decision to isolate its grid from the rest of the country.

That means that when things are running smoothly, Texas can’t export excess power to neighboring states. And in the current crisis, it can’t import power either.
