Building a tool for more efficient software coding: USask research – News


Unfortunately, software errors (bugs) can have massive economic impacts, with only 606 bugs costing $1.7 trillion worldwide in 2017, affecting 3.7 billion people and over 300 companies,” said Bhattacharjee.

Software bugs have the potential to put humans in dangerous situations. Glitches in flight control software can lead to fatal plane crashes or errors in self-driving car programs can cause an increased risk of accidents.

“The ratio of reading versus writing code is almost nine to one. Therefore, by guiding developers to read code more effectively and efficiently, we can minimize developers’ time, ultimately reducing software cost and encouraging more bug-free software.”

To combat bugs during the software developing process, Bhattacharjee and research supervisors Dr. Banani Roy (PhD) and Dr. Kevin Schneider (PhD) from the USask Department of Computer Science are developing a tool to aid developers in reading and writing better code.

The team has been working alongside the USask Global Institute for Water Security, where their source code tool has been used to maintain and develop the Cold Region Hydrological Model (CRHM) software program that is used to predict potential fluxes and states of water and energy in the environment.

Bhattacharjee also developed the back end of the USask Global Water Futures Nutrient App, which allows farmers and scientists across North America to measure water quality by using their phone cameras and low-cost water test kits. The app can measure nutrient concentrations in freshwater and provide water contamination alerts.

In both cases, it is vitally important the information provided to environmental decision makers is as accurate as possible.

“We created an Abstract Code Summary (ACS) tree, an indexed data structure for searching and exploring the codebase in a guided way,” said Bhattacharjee.

The ACS tree provides a way for computer science students and experienced developers to effectively navigate complex computer code and as a result improve their ability to make…

Automotive cyber security must be efficient, scalable and foolproof, says Kaspersky


Vehicle exteriors have undergone sizeable changes over the last ten years, but the real transformation has taken place under the hood. One change is the sheer number of electronic control units (ECUs) modern vehicles contain. Today’s high-end vehicle can require as many as 100 ECUs to function as intended. Complex computing operations such as advanced driver assistance systems (ADAS) and autonomous driving will only add to the required computing power. Though these ECUs can enable connected services or automated driving, every additional link in the chain opens up potential cyber security flaws.

“The autonomous, connected, electric and shared (ACES) trends bring new requirements which modern automotive operating systems need to be capable of handling,” Ilya Efimov, Head of Technology Solutions Development, KasperskyOS told Automotive World. As he detailed, ADAS functionality requires significant computing power. While this power can be integrated, Kaspersky is concerned over the potential vulnerabilities which could be unlocked within safety-critical components. “As more cars are connected to the internet, it is clear that modern internet threats that we see on desktop computers or mobile devices will come to automotive too. Connected cars open a new attack vector,” he added.

Adaptive security

Kaspersky is no stranger to cyber security, and to tackle this new field it has developed the Kaspersky Automotive Adaptive Platform. The company says it offers a software development kit (SDK) with a ‘security-first’ design specifically for automotive, based on the company’s own operating system, KasperskyOS. “We see that this platform will be a solution for automotive vendors to reduce their cost. As the cyber security trend grows in automotive, our operating system is a great fit to combat a rising problem,” said Efimov. “Right now we have a version that automotive developers can use to develop their own applications, and we’re working on launching it commercially next year.”

“As vehicles start to communicate with other vehicles, with road infrastructure, with the wider network, they will also need additional cyber security solutions”

Fastest magnetic read/write ever is incredibly energy efficient

Enlarge / Magnets, how do they work? (credit: Paul Downey (Flickr))

Magnetic media, in the form of disk and tape drives, has been the dominant way of storing bits. But the speed and low power of flash memory has been displacing it from consumer systems, and various forms of long-term memory are in development that are even faster. But a new paper suggests that magnetic media may still be competitive—you just have to stop reading and writing it with magnets.

Using a specific form of garnet and some ultrafast laser pulses, a Dutch-Polish team of researchers performed what they suspect is the fastest read/write of magnetic media ever. And, for good measure, the process was extremely energy efficient.

Heat is actually a problem for both hard drives and flash. Although it doesn’t create a problem in most consumer systems, dealing with excess heat is a major issue in data centers. The problem, according to the authors of the new paper, is one of scale. While we can calculate the minimum energy needed to flip a magnetic bit, we use much more than that to ensure that every bit gets written as intended. Eight orders of magnitude more, in fact. Most of that excess energy ends up dissipating into the environment, where it ends up as heat.
