Ask Slashdot: Have You Read 'The Art of Computer Programming'? (wikipedia.org) 49

In 1962, 24-year-old Donald Knuth began writing The Art of Computer Programming, publishing three volumes by 1973, with volume 4 arriving in 2005. (Volume 4A appeared in 2011, with new paperback fascicles planned for every two years, and fascicle 6, "Satisfiability," arriving last December). "You should definitely send me a resume if you can read the whole thing," Bill Gates once said, in a column where he described working through the book. "If somebody is so brash that they think they know everything, Knuth will help them understand that the world is deep and complicated."

But now long-time Slashdot reader Qbertino has a question: I've had The Art of Computer Programming on my book-buying list for just about two decades now and I'm still torn...about actually getting it. I sometimes believe I would mutate into some programming demi-god if I actually worked through this beast, but maybe I'm just fooling myself...

Have any of you worked through or with TAOCP or are you perhaps working through it? And is it worthwhile? I mean not just for bragging rights. And how long can it reasonably take? A few years?

Canonical Sues Cloud Provider Over 'Unofficial' Ubuntu Images (ostatic.com) 22

An anonymous reader quotes OStatic's update on Canonical's lawsuit against a cloud provider: Canonical posted Thursday that they've been in a dispute with "a European cloud provider" over the use of their own homespun version of Ubuntu on their cloud servers. Their implementation disables even the most basic of security features and Canonical is worried something bad could happen and it'd reflect badly back on them... They said they've spent months trying to get the unnamed provider to use the standard Ubuntu as delivered to other commercial operations to no avail. Canonical feels they have no choice but to "take legal steps to remove these images." They're sure Red Hat and Microsoft wouldn't be treated like this.
Mark Shuttleworth, the founder of Ubuntu, wrote in his blog post that Ubuntu is "the leading cloud OS, running most workloads in public clouds today," whereas these homegrown images "are likely to behave unpredictably on update in weirdly creative and mysterious ways... We hear about these issues all the time, because users assume there is a problem with Ubuntu on that cloud; users expect that 'all things that claim to be Ubuntu are genuine', and they have a right to expect that...

"To count some of the ways we have seen home-grown images create operational and security nightmares for users: clouds have baked private keys into their public images, so that any user could SSH into any machine; clouds have made changes that then blocked security updates for over a week... When things like this happen, users are left feeling let down. As the company behind Ubuntu, it falls to Canonical to take action."

70 Laptops Got Left Behind At An Airport Security Checkpoint In One Month (bravotv.com) 76

America's Transportation Security Administration has been making some surprising announcements on social media. An anonymous reader writes: A TSA spokesperson says 70 laptops were left behind in just one month at an airport security checkpoint in Newark. "And yes, there are plenty of shiny MacBooks in that pile," reported BravoTV, "which can cost in the $2,000 range new." The TSA shared an image of the 70 laptops on their Instagram page and on Twitter, prompting at least one mobile project designer to reclaim his laptop. "The most common way laptops are forgotten is when traveler's stack a bin on top of the bin their laptop is in," the TSA warns. "Out of sight out of mind."
The TSA is also sharing pictures on social media of the 70 guns they confiscated at security checkpoints in one week in November, reporting they've also confiscated a blowtorch, batarangs, and a replica of that baseball bat from "The Walking Dead". They're reporting they found 33 loaded firearms in carry-on luggage in one week, and remind readers that gun-carrying passengers "can face a penalty as high as $11,000. This is a friendly reminder to please leave these items at home."

Sysadmin Gets Two Years In Prison For Sabotaging ISP (bleepingcomputer.com) 78

After being let go over a series of "personal issues" with his employer, things got worse for 26-year-old network administrator Dariusz J. Prugar, who will now have to spend two years in prison for hacking the ISP where he'd worked. An anonymous reader writes: Prugar had used his old credentials to log into the ISP's network and "take back" some of the scripts and software he wrote... "Seeking to hide his tracks, Prugar used an automated script that deleted various logs," reports Bleeping Computer. "As a side effect of removing some of these files, the ISP's systems crashed, affecting over 500 businesses and over 5,000 residential customers."

When the former ISP couldn't fix the issue, they asked Prugar to help. "During negotiations, instead of requesting money as payment, Prugar insisted that he'd be paid using the rights to the software and scripts he wrote while at the company, software which was now malfunctioning, a week after he left." This tipped off the company, who detected foul play, contacted the FBI and rebuilt its entire network.

Six years later, Prugar was found guilty after a one-week jury trial, and was ordered by the judge to pay $26,000 in restitution to the ISP (which went out of business in October of 2015). Prugar's two-year prison sentence begins December 27.

Virginia Police Spent $500K For An Ineffective Cellphone Surveillance System (muckrock.com) 33

Cell-site simulators can intercept phone calls and even provide locations (using GPS data). But Virginia's state police force just revealed details about their actual use of the device -- and it's not pretty. Long-time Slashdot reader v3rgEz writes: In 2014, the Virginia State Police spent $585,265 on a specially modified Suburban outfitted with the latest and greatest in cell phone surveillance: the DRT 1183C, affectionately known as the DRTbox. But according to logs uncovered by public records website MuckRock, the pricey ride was only used 12 times — and only worked seven of those times.
According to Virginia's ACLU director, "each of the 12 uses cost almost $50,000, and only 4 of them resulted in an arrest [raising] a significant question whether the more than half million dollars spent on the device and the vehicle...was a wise investment of public funds."

Are We Seeing Propaganda About Russian Propaganda? (rollingstone.com) 221

MyFirstNameIsPaul was one of several readers who spotted this disturbing instance of fake news about fake news. An anonymous reader writes: Last week the Washington Post described "independent researchers" who'd identified "more than 200 websites as routine peddlers of Russian propaganda" that they estimated were viewed more than 200 million times on Facebook. But the researchers insisted on remaining anonymous "to avoid being targeted by Russia's legions of skilled hackers," and when criticized on Twitter, responded "Awww, wook at all the angwy Putinists, trying to change the subject -- they're so vewwy angwy!!"

The group "seems to have been in existence for just a few months," writes Rolling Stone's Matt Taibbi, calling the Post's article an "astonishingly lazy report". (Chris Hedges, who once worked on a Pulitzer Prize-winning team at the New York Times, even found his site Truthdig on the group's dubious list of over 200 "sites that reliably echo Russian propaganda," along with other long-standing sites like Zero Hedge, Naked Capitalism, and the Ron Paul Institute for Peace and Prosperity.) "By overplaying the influence of Russia's disinformation campaign, the report also plays directly into the hands of the Russian propagandists that it hopes to combat," complains Adrian Chen, who in 2015 documented real Russian propaganda efforts which he traced to "a building in St. Petersburg where hundreds of young Russians worked to churn out propaganda."

The Post's article was picked up by other major news outlets (including USA Today), and included an ominous warning that "The sophistication of the Russian tactics may complicate efforts by Facebook and Google to crack down on 'fake news'."

For The UK's 'Snoopers' Charter', Politicians Voted Themselves An Exemption (independent.co.uk) 102

The "Snoopers' Charter" passed in the U.K. greatly expands the government's surveillance power. But before they'd enact the new Investigatory Powers Act, Britain's elected officials first voted to make themselves exempt from it. Sort of. An anonymous reader writes: While their internet browsing history will still be swept up, just like everyone else's, no one will ever be able to access it without specific approval from the Prime Minister. And according to The Independent, "That rule applies not only to members of the Westminster parliament but also politicians in the devolved assembly and members of the European Parliament."
The article adds that the exemption was the very first amendment they approved for the legislation. And for a very long time, the only amendment.

UK Health Secretary Urges Social Media Companies To Block Cyberbullying And Underaged Sexting (betanews.com) 63

Mark Wilson shares his article on Beta News: Health secretary Jeremy Hunt has made calls for technology companies and social media to do more to tackle the problems of cyberbullying, online intimidation and -- rather specifically -- under-18-year-olds texting sexually explicit images. Of course, he doesn't have the slightest idea about how to go about tackling these problems, but he has expressed his concern so that, in conjunction with passing this buck to tech companies, should be enough, right?
Hunt apparently believes there's already a technology which can identify sexually explicit photos, and that social media networks should now also develop algorithms to identify and block cyberbullying, an idea the Guardian called "sadly laughable."

"Is the blanket censorship of non-approved communications for all under 18s -- something that goes far further than even the Great Firewall of China -- really the kind of thing a government minister should be able to idly suggest in 2016?"

Crooks Need Just Six Seconds To Guess A Credit Card Number (independent.co.uk) 97

schwit1 quotes The Independent: Criminals can work out the card number, expiration date, and security code for a Visa debit or credit card in as little as six seconds using guesswork, researchers have found... Fraudsters use a so-called Distributed Guessing Attack to get around security features put in place to stop online fraud, and this may have been the method used in the recent Tesco Bank hack...

According to a study published in the academic journal IEEE Security & Privacy, fraudsters could use computers to systematically fire different variations of security data at hundreds of websites simultaneously. Within seconds, by a process of elimination, the criminals could verify the correct card number, expiration date and the three-digit security number on the back of the card.

One of the researchers explained this attack combines two weaknesses into one powerful attack. "Firstly, current online payment systems do not detect multiple invalid payment requests from different websites... Secondly, different websites ask for different variations in the card data fields to validate an online purchase. This means it's quite easy to build up the information and piece it together like a jigsaw puzzle."

Devuan's Systemd-Free Linux Hits Beta 2 (theregister.co.uk) 257

Long-time Slashdot reader Billly Gates writes, "For all the systemd haters who want a modern distro feel free to rejoice. The Debian fork called Devuan is almost done, completing a daunting task of stripping systemd dependencies from Debian." From The Register: Devuan came about after some users felt [Debian] had become too desktop-friendly. The change the greybeards objected to most was the decision to replace sysvinit init with systemd, a move felt to betray core Unix principles of user choice and keeping bloat to a bare minimum. Supporters of init freedom also dispute assertions that systemd is in all ways superior to sysvinit init, arguing that Debian ignored viable alternatives like sinit, openrc, runit, s6 and shepherd. All are therefore included in Devuan.
Devuan.org now features an "init freedom" logo with the tagline, "watching your first step. Their home page now links to the download site for Devuan Jessie 1.0 Beta2, promising an OS that "avoids entanglement".

The US Government Funds A War On Online Fake News (bangordailynews.com) 328

An anonymous reader quotes the Washington Post: Congressional negotiators on Wednesday approved an initiative to track and combat foreign propaganda amid growing concerns that Russian efforts to spread "fake news" and disinformation threaten U.S. national security. The measure, part of the National Defense Authorization Act approved by a conference committee, calls on the State Department to lead government-wide efforts to identify propaganda and counter its effects. The authorization is for $160 million over two years...

The Senate Intelligence Committee, meanwhile, has approved language in the fiscal year 2017 intelligence authorization bill calling for new executive branch efforts to combat what it characterized as "active measures" by Russia to manipulate people and governments through front groups, covert broadcasting or "media manipulation." "There is definitely bipartisan concern about the Russian government engaging in covert influence activities of this nature," Sen. Ron Wyden, D-Ore., a member of the Senate Intelligence Committee, said in a statement. "If you read section 501 of this year's intelligence authorization bill, it directs the President to set up an interagency committee to 'counter active measures by Russia to exert covert influence over peoples and governments.'"

Several senators on the intelligence committee also asked President Obama to declassify any information relating to the Russian government and the U.S. election.

It Will Soon Be Illegal To Punish US Customers Who Criticize Businesses Online (arstechnica.com) 81

An anonymous reader writes: Congress has passed a law protecting the right of U.S. consumers to post negative online reviews without fear of retaliation from companies. The bipartisan Consumer Review Fairness Act was passed by unanimous consent in the US Senate, a Senate Commerce Committee announcement said. The bill, introduced in 2014, was already approved by the House of Representatives and now awaits President Obama's signature.

The Consumer Review Fairness Act -- full text available here -- voids any provision in a form contract that prohibits or restricts customers from posting reviews about the goods, services, or conduct of the company providing the product or service. It also voids provisions that impose penalties or fees on customers for posting online reviews as well as those that require customers to give up the intellectual property rights related to such reviews.

VM-Neutral Node.js API Unveiled, As NodeSource Collaborates With Microsoft, Mozilla, Intel and IBM (medium.com) 28

An anonymous reader writes: This week saw the first proof of concept for Node.js API (or NAPI for short), "making module maintainers' lives easier by defining a stable module API that is independent from changes in [Google's JavaScript engine] V8 and allowing modules to run against newer versions of Node.js without recompilation." Their announcement cites both the efforts of the Node.js API working group and of ChakraCore, the core part of the Chakra Javascript engine that powers Microsoft Edge.

And there was also a second announcement -- that the Node.js build system "will start producing nightly node-chakracore builds, enabling Node.js to be used with the ChakraCore JavaScript engine. "These initial efforts are stepping stones to make Node.js VM-neutral, which would allow more opportunities for Node.js in IoT and mobile use cases as well as a variety of different systems."

One IBM runtime developer called it "a concrete step toward the strategic end goal of VM neutrality," and the Node.js Foundation believes that the API will ultimately result in "more modules to choose from, and more stability with modules without the need to continually upgrade."

Drupal Event Apologizes For Giving Out Copies Of Playboy (drupalcamp.de) 229

An anonymous reader writes: The organization team for a regional Drupal event apologized Thursday for distributing copies of Playboy to attendees. The magazines were distributed in welcome bags, according to a statement from the organizers of DrupalCamp Munich, and "were provided by Burda, a major German publisher, who also provided other technical magazines as part of their sponsorship. These magazines were approved for inclusion by the camp organizers.

"At the time, we thought it would be a good idea, as playboy.de was one of the first major Drupal 8 websites ever released. Upon reflection, this wasn't the best idea, and the magazines have been removed... It was a decision made in poor taste, and we regret it.

The inclusion of the magazine had attracted criticism on Twitter from both male and female developers, with one writing sarcastically, "Dunno about you, but I only read playboy.de for the Drupal code."
