Low-code is paving the way to a more tech-savvy workforce and more opportunities for technology professionals. 'That's a game changer, it's a life changer.'

The fallout continues between University of Minnesota researchers and the Linux kernel developers after the researchers described how they had intentionally submitted some commits to the Linux kernel that would introduce vulnerabilities, in a paper titled “On the Feasibility of Stealthily Introducing Vulnerabilities in Open-Source Software via Hypocrite Commits,” detailing how they had intentionally submitted some…

In my last week of high school in 1996, I quit my job at Carl's Jr. because I thought maybe without school, I'd have time to learn enough skills to get hired at a PC shop or something. I didn't know that I actually had incredibly marketable skills as a Linux sysadmin and C programmer, because I was the only tech person I'd ever known (except the people I chatted with on Undernet's #LinuxHelp channel).

In the words of Dan Kaminsky, the legendary DNS hacker, "the Internet's proven to be a pretty big deal for global society." For the Internet to work, computers must be able to find one another on the most complex network of all: the World Wide Web. This was the problem posed to government workers and academic IT staff a few decades ago, and it's their solutions that we use today.

Digital platforms and transformation efforts are not an advantage by themselves; it's what businesses do with those platforms that matters.

The challenge of software testing is immensely underestimated and invariably unappreciated. Even with seemingly basic applications, like a common mobile app, there are a staggering number of testing approaches you could take, paths and conditions you could exercise, device configurations you could test against, and so on.

The U.S. Army has released stunning footage of their new night vision technology, demonstrated by the Enhanced Night Vision Goggle-Binocular (ENVG-B). It has to be seen to be believed: The previous generation of night vision featured a greenish glow, because the images were generated by electrons traveling through a

Matias Bjørling was only 28 when he developed the initial Open Channel SSD architecture (for solid-state drives), pushing for what he called “the necessary death of a block device interface.” He argued that the conventional block interface, which arbitrarily reads and writes to SSD data blocks, had a major impact on the throughput, latency and…
