Interviews

I was introduced to Linux in the era of Red Hat Linux 9, but I thought it *was* Linux, and when "Enterprise" was added I stopped using it. Several years ago, I picked up Ubuntu and started using it full time. More recently, besides use at home, I applied what knowledge I have of Linux to a robotics competition, using the Raspberry Pi, hosted by the American Society of Agricultural & Biological Engineers in New Orleans last year. When a similar competition was assigned to an introductory Control Theory class I took last semester, the professor opted to have me assist the TA and all my classmates in teaching basic Linux skills and Python programming to do a simple maze following project.

Google Developer Kees Cook Details The Linux Kernel Self-Protection Project

Google

At the Linux Security Summit last month, Google developer Kees Cook shared the current workings of the Kernel Self-Protection Project (KSPP). The project, he said, goes beyond user space and even beyond kernel integrity. The idea is to implement changes to help the kernel protect itself.

To understand the importance of the project, Cook said, we need to think about the multitude of devices running Linux, such as servers, laptops, cars, phones, and then consider that the vast majority of these devices are running old software, which contains bugs. Some of these devices have very long lifetimes, but the lifetime of a bug can be longer still.

Linux

The feedback from our first alpha release has reported the Moksha desktop on the 16.04 base is as stable as ever, so the only reason this remains with a pre-release tag is due to some rough edges in terms of polish. There are some minor issues with the default theme under our new 16.04 base and I am still looking to make time to compile a non-PAE kernel image and create a separate disc image for that.

  • But is it safe? Uncork a bottle of vintage open-source FUD
    Most of the open source questioners come from larger organisations. Banks very rarely pop up here, and governments have long been hip to using open source. Both have ancient, proprietary systems in place here and there that are finally crumbling to dust and need replacing fast. Their concerns are more oft around risk management and picking the right projects. It’s usually organisations whose business is dealing with actual three dimensional objects that ask about open source. Manufacturing, industrials, oil and gas, mining, and others who have typically looked at IT as, at best, a helper for their business rather than a core product enabler. These industries are witnessing the lighting fast injection of software into their products - that whole “Internet of Things” jag we keep hearing about. Companies here are being forced to look at both using open source in their products and shipping open source as part of their business. The technical and pricing requirements for IoT scale software is a perfect fit for open source, especially that pricing bit. On the other end - peddling open source themselves - companies that are looking to build and sell software-driven “platforms” are finding that partners and developers are not so keen to join closed source ecosystems. These two pulls create some weird clunking in the heads of management at these companies who aren’t used to working with a sandles and rainbow frame of mind. They have a scepticism born of their inexperience with open source. Let’s address some of their trepidation.
  • Real business innovation begins with open practices
    To business leaders, "open source" often sounds too altruistic—and altruism is in short supply on the average balance sheet. But using and contributing to open source makes hard-nosed business sense, particularly as a way of increasing innovation. Today's firms all face increased competition and dynamic markets. Yesterday's big bang can easily become today's cautionary tale. Strategically, the only viable response to this disruption is constantly striving to serve customers better through sustained and continuous innovation. But delivering innovation is hard; the key is to embrace open and collaborative innovation across organizational walls—open innovation. Open source communities' values and practices generate open innovation, and working in open source is a practical, pragmatic way of delivering innovation. To avoid the all-too-real risk of buzzword bingo we can consider two definitions of "innovation": creating value (that serves customer needs) to sell for a profit; or reducing what a firm pays for services.
  • This Week In Servo 79
    In the last week, we landed 96 PRs in the Servo organization’s repositories. Promise support has arrived in Servo, thanks to hard work by jdm, dati91, and mmatyas! This does not fully implement microtasks, but unblocks the uses of Promises in many places (e.g., the WebBluetooth test suite). Emilio rewrote the bindings generation code for rust-bindgen, dramatically improving the flow of the code and output generated when producing Rust bindings for C and C++ code. The TPAC WebBluetooth standards meeting talked a bit about the great progress by the team at the University of Szeged in the context of Servo.
  • Servo Web Engine Now Supports Promises, Continues Churning Along
    It's been nearly two months since last writing about Mozilla's Servo web layout engine (in early August, back when WebRender2 landed) but development has kept up and they continue enabling more features for this next-generation alternative to Gecko. The latest is that Servo now supports JavaScript promises. If you are unfamiliar with the promise support, see this guide. The latest Servo code has improvements around its Rust binding generator for C and C++ code plus other changes.
  • Riak TS for time series analysis at scale
    Until recently, doing time series analysis at scale was expensive and almost exclusively the domain of large enterprises. What made time series a hard and expensive problem to tackle? Until the advent of the NoSQL database, scaling up to meet increasing velocity and volumes of data generally meant scaling hardware vertically by adding CPUs, memory, or additional hard drives. When combined with database licensing models that charged per processor core, the cost of scaling was simply out of reach for most. Fortunately, the open source community is democratising large scale data analysis rapidly, and I am lucky enough to work at a company making contributions in this space. In my talk at All Things Open this year, I'll introduce Riak TS, a key-value database optimized to store and retrieve time series data for massive data sets, and demonstrate how to use it in conjunction with three other open source tools—Python, Pandas, and Jupyter—to build a completely open source time series analysis platform. And it doesn't take all that long.

  • Time to Kill Security Questions—or Answer Them With Lies
    The notion of using robust, random passwords has become all but mainstream—by now anyone with an inkling of security sense knows that “password1” and “1234567” aren’t doing them any favors. But even as password security improves, there’s something even more problematic that underlies them: security questions. Last week Yahoo revealed that it had been massively hacked, with at least 500 million of its users’ data compromised by state sponsored intruders. And included in the company’s list of breached data weren’t just the usual hashed passwords and email addresses, but the security questions and answers that victims had chosen as a backup means of resetting their passwords—supposedly secret information like your favorite place to vacation or the street you grew up on. Yahoo’s data debacle highlights how those innocuous-seeming questions remain a weak link in our online authentication systems. Ask the security community about security questions, and they’ll tell you that they should be abolished—and that until they are, you should never answer them honestly. From their dangerous guessability to the difficulty of changing them after a major breach like Yahoo’s, security questions have proven to be deeply inadequate as contingency mechanisms for passwords. They’re meant to be a reliable last-ditch recovery feature: Even if you forget a complicated password, the thinking goes, you won’t forget your mother’s maiden name or the city you were born in. But by relying on factual data that was never meant to be kept secret in the first place—web and social media searches can often reveal where someone grew up or what the make of their first car was—the approach puts accounts at risk. And since your first pet’s name never changes, your answers to security questions can be instantly compromised across many digital services if they are revealed through digital snooping or a data breach.

  • Record-breaking DDoS reportedly delivered by >145k hacked cameras
    Last week, security news site KrebsOnSecurity went dark for more than 24 hours following what was believed to be a record 620 gigabit-per-second denial of service attack brought on by an ensemble of routers, security cameras, or other so-called Internet of Things devices. Now, there's word of a similar attack on a French Web host that peaked at a staggering 1.1 terabits per second, more than 60 percent bigger. The attacks were first reported on September 19 by Octave Klaba, the founder and CTO of OVH. The first one reached 1.1 Tbps while a follow-on was 901 Gbps. Then, last Friday, he reported more attacks that were in the same almost incomprehensible range. He said the distributed denial-of-service (DDoS) attacks were delivered through a collection of hacked Internet-connected cameras and digital video recorders. With each one having the ability to bombard targets with 1 Mbps to 30 Mbps, he estimated the botnet had a capacity of 1.5 Tbps. On Monday, Klaba reported that more than 6,800 new cameras had joined the botnet and said further that over the previous 48 hours the hosting service was subjected to dozens of attacks, some ranging from 100 Gbps to 800 Gbps. On Wednesday, he said more than 15,000 new devices had participated in attacks over the past 48 hours.
