World War III has started, and almost no one seems to have noticed. Or perhaps the Cold War is a better analogy, if the Cold War had 20 sides fighting each other all at once and, again, if almost no one was paying enough attention to realize what is going on.

At least, this is what Alexander Klimburg insists in The Darkening Web, his new book on the battles of cyberspace. It's a quiet war, in the sense that few have died thus far, but it has the potential to be murderous, and every year raises the stakes of that war. The Chinese may be the world's leading players, but in November 2014, North Korea raised its status by stealing and posting publicly confidential information from the Sony corporation, and then erasing Sony's computersall in revenge for a minor comedy film mocking Kim Jong Un.

And then, of course, there are the Russians, both on the level of government and the level of individual criminals. In December 2015, during the Russian Army's push into Ukraine, Klimburg points out, "Ukraine became the first country to suffer a verified large-scale cyber attack on its critical infrastructure. Over 225,000 Ukrainians lost their light and heating in the middle of winter when a cyberattack disabled part of the country's power grid."

Meanwhile, we have hackers for money and hackers for mischief and even hackers on a mission, conducting distributed-denial-of-service attacks and information thefts in the name of one ideology or another. This spring, 16 hospitals in Great Britain were shut down by the WannaCry ransomware virus, which locked patients' computerized records until a small ransom had been paid to a bitcoin account. Similar attacks occurred across Europe and in the United States.

The United States has committed its share of these attacks. In 2009, the centrifuges Iran was using to enrich uranium were sabotaged with the Stuxnet virus, which is now generally agreed to have been a joint American-Israeli exploit. As far as that goes, the United States conducted the first massively successful international hack all the way back in 1981. The CIA learned from its KGB double agent Vladimir Vetrov that the Soviets were looking for software to control the trans-Siberian pipeline. So the CIA allowed the Soviets to steal a sabotaged version of the American software, which in 1982 caused an explosion large enough to be seen from space that destroyed a large portion of the Russian pipeline. Depriving the Soviets of potentially $8 billion a year in oil revenues, it is probably the greatest spy exploit achieved during the Cold War.

But these days the United States mostly operates as something like the backstop, the guarantor of world order, in the new cybernetic space. Or, at least, that's how it should be. There looms "an Armageddon," Klimburg writes, that only the "liberal democracies have the power to avert." But the American spy agencies have reserved for themselves the right to act as international rogue warriors in the cyber realm and thereby weaken the power of the United States to keep the internet in balance. The WannaCry ransomware attack exploited a mysteriously leaked vulnerability in Microsoft Windows that the NSA had previously discovered but not reported, hoping to use the vulnerability for its own spy work. Again and again, Klimburg insists, the American attempt "to achieve total dominance" in internet warfare "can be safely said to have totally backfired."

The overwriting and failure of tone in such clauses form a problem for The Darkening Web. Sentence by sentence, Klimburg just isn't a good writer, studding his text with confusing acronyms and launching into unnecessarily long-winded explanations of topics that weren't necessary for his point in the first placeas when he wanders into an excursus about "path dependency" without much of a clear path back out again.

Chapter by chapter, however, Klimburg has written a powerful and frightening book. The internet is, he thinks, "a fabulous artifice of human civilization," and its (mostly libertarian) early proponents taught us the belief that it would be a device "for advancing freedoms and prosperity." Unfortunately, the current direction of the Cold War of Cyberspace means it may well "become instead a dark web of subjugation." The "international cyber arms race" is "threatening the overall stability and security . . . of our very societies."

The Darkening Web asks us to distinguish three different species of computer attacks. The first is the genuinely and immediately violent: the cyber equivalent of actual war in which we hack a system to turn off automated defenses or cause a dam or a power grid to fail. The 2015 Russian assault on the Ukranian electrical system makes for a clear example.

The second form of computerized attack is the hack for informationloudly announced when done for political effect, but often kept quiet as secret spy work. The phishing attack that cracked the Democratic party's email servers during the 2016 presidential race is an obvious case of an attack in search of embarrassing or sensitive information.

Finally, there is the role of propaganda through the internet, in the form of pushing fake news or the form of restricting disfavored speech. Russia dominates recent press accounts about the first form, but China is the master of the second. Under pressure from Beijing, Apple recently removed from its app store hundreds of apps for its Chinese customers, including the app for the New York Times. The list of words banned by China for social media runs for pages.

Klimburg doesn't give his readers much of a solution for all of this. He insists that the internet needs to remain free, in order to combat the propagandists, but the freedom of the internet is exactly what the other two kinds of computerized attack rely on when they insinuate themselves into sensitive places.

What Klimburg does see clearly, however, is the opportunity that the "internet of things" offers for hacking. Our cars, our refrigerators, our crockpots, and our cameras are increasingly connected to the web these days, and there are, by one estimate, 25 billion devices online in the world today. Each of them is vulnerable and each of them offers a small opportunity for corruption, an accident waiting to happen. As that interconnectedness is extended to our power grids, our sewer systems, and our transportation networks, the chance for murderous attacks grows every year.

The Cyber Cold War is being fought among a swirl of opponents in a swirl of battles. It resembles the original Cold War in the fact that government-sponsored attacks on major institutions are avoided out of fear of retaliation. For that matter, it mirrors the old struggle against the Soviets in its constantly changing naturerequiring the United States always to keep moving ahead, just to stay even.

The Minifree Libreboot T400 is free as in freedom – TechCrunch

The Libreboot T400 doesnt look like much. Its basically a refurbished Lenovo Thinkpad with the traditional Lenovo/IBM pointer nubbin and a small touchpad. Its a plain black laptop, as familiar as any luggable assigned to a cubicle warrior on the road. But, under the hood, you have a machine that fights for freedom.

The T400 runs Libreboot, a free and open BIOS and the Trisquel GNU/Linux OS. Both of these tools should render the Libreboot T400 as secure from tampering as can be. Your Libreboot T400 obeys you, and nobody else! write its creators, and that seems to be the case.

How does it work? And should you spend about $300 on a refurbished Thinkpad with Linux installed? That depends on what youre trying to do. The model I tested was on the low end with enough speed and performance to count but Trisquel tended to bog down a bit and the secure browser, an unbranded Mozilla based browser that never recommends non-free software, was a little too locked down for its own good. I was able to work around a number of the issues I had but this is definitely not for the faint of heart.

That said, you are getting a nearly fully open computer. The 14.1-inch machine runs a Intel Core 2 Duo P8400 processor and starts at 4GB of RAM with 160GB hard drive space. That costs about $257 plus shipping and includes a battery and US charger.

Once you have the T400 youre basically running a completely clean machine. It runs a free (as in freedom) operating system complete with open drivers and applications and Libreboot ensures that you have no locked-down software on the machine. You could easily recreate this package yourself on your own computer but I suspect that you, like me, would eventually run into a problem that couldnt be solved entirely with free software. Hence the impetus to let Minifree do the work for you.

If youre a crusader for privacy, security, and open standards, than this laptop is for you. Thankfully its surprisingly cheap and quite rugged so youre not only sticking it to the man but you could possibly buy a few of these and throw them at the man in a pinch.

The era of common Linux on the desktop and not in the form of a secure, libre device like this is probably still to come. While its trivial (and fun) to install a Linux instance these days I doubt anyone would do it outright on a laptop that theyre using on a daily basis. But for less than a price of a cellphone you can use something like the T400 and feel safe and secure that youre not supporting (many) corporate interests when it comes to your computing experience. Its not a perfect laptop by any stretch but its just the thing if youre looking for something that no one but you controls.

Open-source entrepreneurship – MIT News

Open-source software is free software whose underlying code, or source code, is also freely available. Open-source development projects often involve hundreds or even thousands of volunteer coders scattered around the globe. Some of the best known are the Linux operating system, the Firefox web browser, and the WordPress blogging platform.

This past spring, MIT professor of electrical engineering and computer science Saman Amarasinghe offered 6S194 (Open-Source Entrepreneurship), a new undergraduate course on initiating and managing open-source development projects. The course had no exams or problem sets; instead, the assignments included consulting with mentors, interviewing users, writing a promotional plan and, of course, leading the development of an open-source application.

The course is an example of an academic trend toward project-based curricula, which have long had vocal supporters among educational theorists but have drawn renewed attention with the advent of online learning, which turns lectures and discussions into activities that students can pursue on their own schedules.

But where many project-based undergraduate engineering classes result in designs or products that may not make it out of the classroom, the goal of the new MIT class was a public software release, complete with marketing campaign. And the students learned not only the technical skills required to complete their projects, but the managerial skills required to initiate and guide them.

The creation of the course had a number of different motivations, Amarasinghe explains. MIT is a very structured place, and we ask so much of our students, sometimes they dont have time to do anything interesting outside, he says. When you talk to students, they say, We have ideas, but without credit, we don't have time to do it.

The other thing that happened was that for the last three, four years, Facebook had this Facebook Open Academy that got students from multiple universities and paired them up with open-source projects, Amarasinghe adds. What I found was a lot of times MIT students were somewhat bored with some of those projects because its hard to meet MIT expectations. We have much higher expectations of what the kids can do.

A third factor, Amarasinghe says, is that many research projects in computer science spawn software that, even though it represents hundreds of hours of work by brilliant coders, never makes it out of the lab. Open-source projects that clean that software up, fill in gaps in its functionality, and create interfaces that make it easy to use could mean that researchers working on related projects, instead of building their own systems from scratch, could modify the code of existing systems, saving a huge amount of time and energy.

Entrepreneurial expectations

Classes for Open-Source Entrepreneurship were divided between lectures and studio time, in which teams of students could work on their projects. Amarasinghe lectured chiefly on technical topics, and Nick Meyer, entrepreneur-in-residence at the Martin Trust Center for MIT Entrepreneurship, lectured on topics such as market research and marketing. During studio time, both Amarasinghe and Meyer were available to advise students.

Before the class launched, Amarasinghe and his teaching assistant, Jeffrey Bosboom, a graduate student in electrical engineering and computer science, had identified several MIT research projects that they thought could be the basis of useful open-source software. But students were free to propose their own projects.

After selecting their projects, the students first task was to meet with or, in the case of the students who proposed their own projects, identify and then meet with mentors, to sketch out the scope and direction of the projects. Then, for each project, the students had to identify and interview four to six potential users of the resulting software, to determine product specifications.

When you start out with the project, you have certain preconceptions about what the problem is and what you have to do to solve that problem, says Stephen Chou, an MIT graduate student in electrical engineering and computer science, who audited the course. One of the first things we had to do was to look for potential users of our project, and when you talk to them, you realize that the priorities that you start out with arent necessarily the right ones. At the same time, some of the people we talked to were working in fields that were completely unfamiliar, at least to me. So you start learning more about their problems, and sometimes you get completely new ideas. Its a good way to orient yourself. That was new to me, and it was very helpful.

The third stage of the project was the establishment of a software development timeline, and at the end of the semester, as the projects drew to completion, the students final assignment was the development of a promotional plan.

The projects

Several of the class projects built on software prototypes that had been developed by the students themselves or by their friends. One project, Gavel, was a system for scoring entries in contests such as science fairs or hackathons, in which teams of programmers develop software to meet specific criteria over the space of days. The initial version had been written by an MIT undergrad who was himself a frequent hackathon participant, and two of his friends agreed to use Amarasinghes course to turn the software into an open-source project.

Typically, hackathon judges use some sort of absolute rating scale, but this is a notoriously problematic approach: Different judges may calibrate the scales differently, and over the course of a contest, judges may recalibrate their own scales if they find that, in assigning their first few scores, they over- or underestimated the competition.

A better approach is to ask judges to perform pairwise comparisons. Comparisons are easier to aggregate across judges, and individual judgments of relative value tend not to fluctuate. Gavel is a web-based system that sequentially assigns judges pairs of contestants to evaluate, selecting the pairs on the fly to ensure that the final cumulative ranking will be statistically valid.

Another of the projects, Homer, also reflects the preoccupations of undergraduates at a technical university. Homer is based on psychological research on the frequency with which factual information must be repeated before it will reliably lodge itself in someones memory. Its essentially a digital flash-card system, except that instead of picking cards entirely at random, it cycles them through at intervals selected to maximize retention.

Other projects, however, grew out of academic research at MIT. One project dubbed Taco, for tensor algebra compiler was based on yet-unpublished research from Amarasinghes group. A tensor is the higher-dimensional analogue of a matrix, which is essentially a table of data. Mathematical operations involving huge tensors are common in the Internet age: All the ratings assigned individual movies by individual Netflix subscribers, for instance, constitute a three-dimensional tensor.

If the tensors are sparse, however if most of their entries are zero there are computational short cuts for manipulating them. And again, in the internet age, many tensors are sparse: Most Netflix subscribers have rated only a tiny fraction of the movies in Netflix library.

Taco provides a simple, intuitive interface to let data scientists describe operations involving sparse and nonsparse tensors, and the underlying algorithms automatically generate the often very complicated computer code for executing those operations as efficiently as possible.

Other projects from the class such as an interface for a database of neural-network models, or a collaborative annotation tool designed for use in the classroom also grew out of MIT research. But no matter the sources of the projects, the students were the ones steering them to completion.

They had a lot more ownership of a project than being part of a very large project that has thousands of contributors, finding a few bugs or adding a few features, Amarasinghe says. They got to think of the big-picture issues how to build a community, how to attract other programmers, what sort of licensing should be used. MIT students should be the ones who are doing new open-source projects and leading some of these things.
