How to crack the coding challenge

Even for the most seasoned software engineer or developer with a background education in computer science or engineering, completing a coding challenge or a technical screening can be nerve-wracking. Now, imagine you’re a self-taught developer -- the anxiety levels skyrocket.But formal education in computer science, software programming and/or engineering is not mandatory, and in the current IT talent war, the need for those credentials is diminishing further. Many self-taught coders are just as competent as those with a formal degree. The trick is getting past the unconscious biases levied against those without a degree.“From talking to self-taught programmers, I’ve found that one of their biggest sources of fear is the knowledge that they don’t have a degree. Non-traditional candidates are really intimidated by technical screenings, coding interviews, because they’ve been made to feel they’re not qualified without that computer science degree. But I don’t feel that’s true,” says Gayle Laakmann McDowell, founder of technical career consulting firm CareerCup and author of Cracking the Coding Interview.To read this article in full or to leave a comment, please click here

DDN Turns The Crank On “Wolfcreek” Storage

In the high performance computing arena, the stress is always on performance. Anything and everything that can be done to try to make data retrieval and processing faster ultimately adds up to better simulations and models that more accurately reflect the reality we are trying to recreate and often cast forward in time to figure out what will happen next.

Pushing performance is an interesting challenge here at the beginning of the 21st century, since a lot of server and storage components are commoditized and therefore available to others. The real engineering is coming up with innovative ways of putting …

Carnegie Mellon researchers visualize way to fend off DDoS attacks

Following the massive DDoS attack that last month that targeted DNS provider Dyn and temporarily knocked Twitter, Netflix and other big names off the Internet, we were bombarded with pitches from vendors begging to offer their expert opinions on the matter while extolling the virtues of their solutions that naturally would have safeguarded organizations.Now, a couple of weeks later, Carnegie Mellon's CyLab Security and Privacy Institute too is touting research that it says shows that the tools really needed to stymie such attacks are on the way. Somehow, this seems more believable than some of the all-to-eager vendor claims, though it doesn't appear the tools will quite be ready to fly for imminent DDoS attack candidates, such as 2016 U.S. Presidential Election-related sites and Black Friday 2016 websites.To read this article in full or to leave a comment, please click here

Worth Reading: Blocking DDoS at Domain Registration

PREDATOR which stands for ‘Proactive Recognition and Elimination of Domain Abuse at Time-Of-Registration,’ is based on the notion that criminals need to obtain many domains to ensure profitability and attack agility, leading to abnormal registration behaviors such as burst registrations and textually similar names. “The intuition has always been that the way that malicious actors use online resources somehow differs fundamentally from the way legitimate actors use them,” says Princeton University computer science professor Nick Feamster — one of the researchers who worked on the project. “We were looking for those signals: what is it about a domain name that makes it automatically identifiable as a bad domain name?” —CircleID

After protest, Lenovo brings Linux compatibility to Yoga 900 and 900S

Lenovo created a stir when it said the Yoga 900 and 900S hybrids would work only with Windows, not Linux. The company has now changed its stance, bringing Linux support to those PCs.The PC maker earlier this month issued a BIOS update so Linux can be loaded on Yoga 900, 900S and IdeaPad 710 models.The BIOS update adds an AHCI (Advance Host Controller Interface) SATA controller mode so users can load Linux on the laptops.This is a Linux-only BIOS, meaning it should be used only by those who want to load the OS. If you want to continue with Windows, do not load the firmware.To read this article in full or to leave a comment, please click here

Android patches fix Drammer RAM attack, but not Dirty Cow exploit

Google released a new monthly batch of security patches for Android, fixing a dozen critical vulnerabilities that could allow attackers to compromise devices. One of the mitigated issues is a bit-flipping attack against memory chips that could lead to privilege escalation, but a more widespread rooting vulnerability in the Linux kernel remains unpatched.While Google releases firmware updates for its Nexus and Pixel devices on the first Monday of every month, the security patches are shared with third-party device manufacturers one month in advance and are also contributed later to the Android Open Source Project to benefit the entire ecosystem.To read this article in full or to leave a comment, please click here

French plan for biometric database of 60 million people sparks outcry

When the French government quietly announced, in the middle of a holiday weekend, the merging of two files to create a megadatabase holding the biometrics of almost 60 million French citizens, it was clearly hoping to avoid an outcry. It failed. Among those lining up to criticize the government's move are its own minister of state for the Digital Sector and Innovation, and the National Digital Council, a body created by the government to provide independent recommendations on all matters relating to the effect of digital technologies on society and the economy. Minister of State Axelle Lemaire told French journalists the megadatabase used 10-year-old technology and had real security problems.To read this article in full or to leave a comment, please click here

At campaign’s end, Trump takes a swipe at IBM

In Minnesota on Sunday, Republican presidential nominee Donald Trump added IBM to the list of companies he criticizes for moving jobs offshore or to Mexico. Trump's line was a one sentence throwaway at the Twin Cities rally, but it may have resonated with this rally crowd.In Rochester, Minn., IBM created a massive operation. In 1956, it broke ground on what would become a 32-building, 3.5-million-square-foot complex that employed 8,100 workers at its peak in 1991. It made punch card systems and later became widely known for its AS/400 system development work.IBM created a stable workforce, and by 1988 was able to point out that the average Rochester employee was 39.5 years old and a 14-year IBM veteran. Nearly 40% of those workers were engineers or programmers, according to IBM's official history.To read this article in full or to leave a comment, please click here

Make your emails more trusted with DKIM

The war against spam has been a long one. Just as we get better filtering, spammers and phishers turn to more sophisticated techniques. We are even seeing ransomware attacks like Cryptolocker and Cryptowall become commonly spread over email. There must be a technical way to stop some of this, right?There is an Internet authentication system -- DomainKeys, and its successor, DKIM -- that tries to mitigate some of the risk of trusting that emails are actually from who they say they are from. Strangely, though, this technology has not made its way into Microsoft Exchange. In this piece, I want to open the curtains on DomainKeys and DKIM, show how they work and why what they do is important, and then demonstrate how to use a free utility to set up DKIM on your on-premises Exchange servers.To read this article in full or to leave a comment, please click here(Insider Story)
