Walmart Canada claims that it was microservices that allowed them to replace hardware with virtual servers, reducing costs by somewhere between 20 and 50 percent. Now Slashdot reader snydeq shares an article by a senior systems automation engineer arguing that a microservices approach "offers increased modularity, making applications easier to develop, test, deploy, and, more importantly, change and maintain."
The article touts things like cost savings and flexibility for multiple device types, suggesting microservices offer increased resilience and improved scalabiity (not to mention easier debugging and a faster time to market with an incremental development model). But it also warns that organizations need the resources to deploy the new microservices quicky (and the necessary server) -- along with the ability to test and monitor them for database errors, network latency, caching issues and ongoing availability. "You must embrace devops culture," argues the article, adding that "designing for failure is essential... In a traditional setting, developers are focused on features and functionalities, and the operations team is on the hook for production challenges. In devops, everyone is responsible for service provisioning -- and failure."
The original submission ends with a question for Slashdot reader. "What cautions do you have to offer for folks considering tapping microservices for their next application?"Read Replies (0)

"Guido Vranken recently published 4 security vulnerabilities in OpenVPN on his personal blog," writes long-time Slashdot reader randomErr -- one of which was a critical remote execution bug. Though patches have been now released, there's a lesson to be learned about the importance of fuzzing -- bug testing with large amounts of random data -- Guido Vranken writes:
Most of these issues were found through fuzzing. I hate admitting it, but...the arcane art of reviewing code manually, acquired through grueling practice, are dwarfed by the fuzzer in one fell swoop; the mortal's mind can only retain and comprehend so much information at a time, and for programs that perform long cycles of complex, deeply nested operations it is simply not feasible to expect a human to perform an encompassing and reliable verification.
ZDNet adds that "OpenVPN's audits, carried out over the past two years, missed these major flaws. While a handful of other bugs are found, perhaps OpenVPN should consider adding fuzzing to their internal security analysis in the future." Guido adds on his blog, "This was a labor of love. Nobody paid me to do this. If you appreciate this effort, please donate BTC..."Read Replies (0)

An anonymous reader quotes the Guardian:
Parliament has been hit by a "sustained and determined" cyber-attack by hackers attempting to gain access to MPs' and their staffers' email accounts. Both houses of parliament were targeted on Friday in an attack that sought to gain access to accounts protected by weak passwords... The estate's digital services team said they had made changes to accounts to block out the hackers, and that the changes could mean staff were unable to access their emails...
The international trade secretary, Liam Fox, told ITV News the attack was a "warning to everyone we need more security and better passwords. You wouldn't leave your door open at night." In an interview with the BBC, he added: "We know that there are regular attacks by hackers attempting to get passwords. We have seen reports in the last few days of even Cabinet ministers' passwords being for sale online. We know that our public services are attacked, so it is not at all surprising that there should be an attempt to hack into parliamentary emails."
One member of Parliament posted on Twitter "Sorry, no parliamentary email access today â" we're under cyber-attack from Kim Jong-un, Putin or a kid in his mom's basement or something." He added later, "I'm off to the pub."Read Replies (0)

msm1267 writes: Linux, BSD, Solaris and other open source systems are vulnerable to a local privilege escalation vulnerability known as Stack Clash that allows an attacker to execute code at root. Major Linux and open source distributors made patches available Monday, and systems running Linux, OpenBSD, NetBSD, FreeBSD or Solaris on i386 or amd64 hardware should be updated soon. The risk presented by this flaw, CVE-2017-1000364, becomes elevated especially if attackers are already present on a vulnerable system. They would now be able to chain this vulnerability with other critical issues, including the recently addressed Sudo vulnerability, and then run arbitrary code with the highest privileges, said researchers at Qualys who discovered the vulnerability.Read Replies (0)

Long-time Slashdot reader destinyland got a surprise when he visited his local bookstore:
Jon Katz turns 70 this August, and he's published a new book called Talking to Animals: How You Can Understand Animals and They Can Understand You. Katz was a former newspaper reporter (and a contributing editor to Rolling Stone) who wrote for HotWired, the first online presence for Wired magazine in the mid-1990s, before becoming a controversial contributor to Slashdot during the site's early days. Katz left Manhattan in the 1990s to live on a farm "surrounded by dogs, cats, sheep, horses, cows, goats, and chickens," according to the book's description, an experience he writes about on his blog. His new book promises that Katz now "marshals his experience to offer us a deeper insight into animals and the tools needed for effectively communicating with them."Read Replies (0)

Phoronix is hosting a 2017 Linux Laptop Survey. From their site:
While Linux laptop compatibility is much better than where it was years ago, it's still not too uncommon to run into display/hybrid issues, shorter battery life under Linux than Windows or macOS, touchpad problems, and other occasional compatibility/performance shortcomings. So we've established this Linux Laptop Survey in conjunction with Linux stakeholders to hopefully gather more feedback that will be useful to many different parties...
The survey will be online until July 6th, after which the results will be publicly available, and will determine the most popular brands, distros, screen sizes, and GPUs, as well as common pain points and popular price points. And one particularly interestng question asks respondents what they'd like to see in a "dream Linux laptop."Read Replies (0)

citadrianne shares a report from The Outline: President Donald Trump's proposed budget seeks to slash $54 billion from social services including programs like Medicaid and Meals on Wheels. As these resources dry up, crowdfunding websites will further entrench themselves as extra-governmental welfare providers in order to fill the gap. For a lucky few, these sites are a lifeline. For most people, they are worthless. Crowdfunding's fatal flaw is that not every campaign ends up getting the money it needs. A recent study published in the journal Social Science & Medicine found that more than 90 percent of GoFundMe campaigns never meet their goal. For every crowdfunding success story, there are hundreds of failures. "As many happy stories as there are in charitable crowdfunding, there are a lot of really worthy causes when you browse these platforms that nobody has given a cent to," Rob Gleasure, professor at the business school of the National University of Ireland, Cork told The Outline. "People haven't come across them."
Feller and Gleasure's report highlighted how fickle crowdfunding can be. Of all the Razoo campaigns started in 2013, they found, more than a third didn't receive any funding at all. According to their report, donors are more likely to give to campaigns that feature lots of pictures and accompanying text.Read Replies (0)

An anonymous reader quotes a report from TorrentFreak: Two years ago, academic publisher Elsevier filed a complaint (PDF) against Sci-Hub and several related "pirate" sites. It accused the websites of making academic papers widely available to the public, without permission. While Sci-Hub is nothing like the average pirate site, it is just as illegal according to Elsevier's legal team, who obtained a preliminary injunction from a New York District Court last fall. The injunction ordered Sci-Hub's founder Alexandra Elbakyan to quit offering access to any Elsevier content. However, this didn't happen. Instead of taking Sci-Hub down, the lawsuit achieved the opposite. Sci-Hub grew bigger and bigger up to a point where its users were downloading hundreds of thousands of papers per day. Although Elbakyan sent a letter to the court earlier, she opted not engage in the U.S. lawsuit any further. The same is true for her fellow defendants, associated with Libgen. As a result, Elsevier asked the court for a default judgment and a permanent injunction which were issued this week. Following a hearing on Wednesday, the Court awarded Elsevier $15,000,000 in damages, the maximum statutory amount for the 100 copyrighted works that were listed in the complaint. In addition, the injunction, through which Sci-Hub and LibGen lost several domain names, was made permanent.Read Replies (0)

OneWeb has been granted approval from the FCC to launch a network of internet-beaming satellites into orbit. FCC chairman Ajit Pai said in a statement: "Humans have long sought inspiration from the stars, from the ancient Egyptians orienting the
pyramids toward certain stars to the Greeks using constellations to write their mythology. In modern
times, we've done the same, with over 1,000 active satellites currently in orbit. Today, the FCC harnesses
that inspiration as we seek to make the promise of high-speed internet access a reality for more Americans, partly through the skies..." The Verge reports: OneWeb plans to launch a constellation of 720 low-Earth orbit satellites using non-geostationary satellite orbit (NGSO) technology in order to provide global, high-speed broadband. The company's goal has far-reaching implications, and would provide internet to rural and hard-to-reach areas that currently have little access to internet connectivity. Additionally, OneWeb has a targets of "connecting every unconnected school" by 2022, and "bridging the digital divide" by 2027. According to OneWeb, the company plans to launch an initial 10 production satellites in early 2018, which, pending tests, will then be followed by a full launch as early as 2019.Read Replies (0)

Jessica Conditt reports via Engadget: President Barack Obama learned of Russia's attempts to hack U.S. election systems in early August 2016, and as intelligence mounted over the following months, the White House deployed secrecy protocols it hadn't used since the 2011 raid on Osama bin Laden's compound, according to a report by The Washington Post. Apparently, one of the covert programs Obama, the CIA, NSA and other intelligence groups eventually put together was a new kind of cyber operation that places remotely triggered "implants" in critical Russian networks, ready for the U.S. to deploy in the event of a pre-emptive attack. The downed Russian networks "would cause them pain and discomfort," a former U.S. official told The Post. The report says CIA director John Brennan, Obama and other officials had at least four "blunt" conversations with Russian officials about its cyber intrusions beginning August 4th. Obama confronted Vladimir Putin in person during a meeting of world leaders in China this past September, the report says, and his administration even sent Russia a warning through a secure channel originally designed to help the two countries avoid a nuclear strike. Moscow apparently responded one week later -- after the U.S. election -- denying the accusation.Read Replies (0)

According to an exclusive report via The Register, "a massive trove of Microsoft's internal Windows operating system builds and chunks of its core source code have leaked online." From the report: The data -- some 32TB of installation images and software blueprints that compress down to 8TB -- were uploaded to betaarchive.com, the latest load of files provided just earlier this week. It is believed the data has been exfiltrated from Microsoft's in-house systems since around March. The leaked code is Microsoft's Shared Source Kit: according to people who have seen its contents, it includes the source to the base Windows 10 hardware drivers plus Redmond's PnP code, its USB and Wi-Fi stacks, its storage drivers, and ARM-specific OneCore kernel code. Anyone who has this information can scour it for security vulnerabilities, which could be exploited to hack Windows systems worldwide. The code runs at the heart of the operating system, at some of its most trusted levels. In addition to this, hundreds of top-secret builds of Windows 10 and Windows Server 2016, none of which have been released to the public, have been leaked along with copies of officially released versions.Read Replies (0)

An anonymous reader quotes a report from TechCrunch: Yesterday The Information reported on allegations made by half a dozen women working in the tech industry who say they have faced unwanted and inappropriate advances from Silicon Valley venture capitalist, Justin Caldbeck, co-founder and managing partner of Binary Capital. The women include Niniane Wang, co-creator of Google Desktop and a prior CTO of Minted; and Susan Ho and Leiti Hsu, co-founders of Journy, a travel planning and booking service. The Information also talked to three other women who said Caldbeck made inappropriate advances to them. It says these women did not want their names disclosed for fear of retaliation from the VC -- and because of wider concerns they might suffer a backlash from men in the industry who don't see inappropriate advances as a problem. Among the allegations made to The Information are that Caldbeck sent explicit text messages to women; that Caldbeck sent messages in the middle of the night suggesting meeting up; that Caldbeck suggested going to a hotel bedroom during a meeting; that Caldbeck made a proposition about having an open relationship; and that Caldbeck grabbed a woman's thigh under the table of a bar during a meeting. Several of the women reported finding Caldbeck's advances so awkward they gave up on continued dealings with him. In Caldbeck's initial statement, he "strongly" denied the allegations and claimed: "I have always enjoyed respectful relationships with female founders, business partners, and investors." However, in response to The Information's story, his tone changed significantly: "Obviously, I am deeply disturbed by these allegations. While significant context is missing from the incidents reported by The Information, I deeply regret ever causing anyone to feel uncomfortable. The fact is that I have been privileged to have worked with female entrepreneurs throughout my career and I sincerely apologize to anyone who I made uncomfortable by my actions. There's no denying this is an issue in the venture community, and I hate that my behavior has contributed to it." Caldbeck has since released a full statement to Axios, where he says he "will be taking an indefinite leave of absence from Binary Capital..."Read Replies (0)

Tesla confirmed yesterday that it is "in talks" with the municipal government of Shanghai to manufacture its vehicles in the country. Tesla said in a statement: "Tesla is working with the Shanghai Municipal Government to explore the possibility of establishing a manufacturing facility in the region to serve the Chinese market. As we've said before, we expect to more clearly define our plans for production in China by the end of the year. Tesla is deeply committed to the Chinese market, and we continue to evaluate potential manufacturing sites around the globe to serve the local markets. While we expect most of our production to remain in the U.S., we do need to establish local factories to ensure affordability for the markets they serve." Quartz reports: The announcement follows more than a year of speculation that the electric-vehicle maker would set up shop in China, and confirms that Tesla is altering its China strategy away from merely exporting vehicles in order to reach more Chinese consumers. Earlier this year, Musk made a stealth visit to China to visit Wang Yang, one of the nation's highest-ranking officials, to discuss Tesla's plans. Tesla has been selling vehicles in China since 2014, but to date, its share of the electric vehicle market remains marginal, at just 2% as of June 2016, according to trade blog CleanTechnica. There are several reasons for this, one of which is price. Tesla currently exports its vehicles to China, and the government places an import tax of 50% on Tesla cars. The sticker price for the most simple Model S in China is $104,972, compared to $69,500 in the US.Read Replies (0)

From an article on The Outline, submitted by two readers: If you're one of the approximately 80 percent of Americans who have suffered from back pain, you may have been referred to a chiropractor for medical help. In the modern-day internet landscape, you'll find chiropractic celebrities like Dr. Josh Axe (1.7 million Facebook followers), Dr. Billy DeMoss (20,000 Facebook followers), and Dr. Eric Berg (472,000 YouTube subscribers) giving advice that goes beyond managing spinal issues. Both in their offices and on social media, chiropractors have adapted to a marketplace that's demanding more than just pain management: they extol the virtues of an "alkaline diet," tell you how to manage stress with detoxing, and wax scientific about the adrenal gland. [...] Chiropractic care, I'm sorry to say, is little more than the buffoonery of a 19th-century lunatic who derived most of his medical theory from seances. It has not evolved much since its creation. Chiropractic beliefs are dangerously far removed from mainstream medicine, and the vocation's practices have been linked to strokes, herniated discs, and even death. Chiropractors can't replace your doctor, and I'm amazed that they're still even allowed to practice. [...] Though some chiropractors are now making an effort to introduce evidence-based practices into their treatment, chiropractic as a whole hasn't evolved like other areas of medicine -- with hypotheses, experimentation, and peer review. Instead, it was birthed by a strange combination of hocus pocus, guesswork, and strongly held religious beliefs.Read Replies (0)

SpaceX has successfully launched and landed a recycled Falcon 9 rocket for the second time. "The rocket's first stage -- the 14-story-tall core that houses the fuel and the rocket's main engines -- touched down on one of the company's autonomous drone ships in the Atlantic Ocean shortly after taking off from a launchpad at nearby Cape Canaveral, Florida," reports The Verge. From the report: This particular rocket previously flew in January, when it was used to put 10 satellites into orbit for communications company Iridium. The rocket then landed on a drone ship in the Pacific Ocean. SpaceX retrieved the rocket and spent the next few months refurbishing it in preparation for today's launch. This afternoon, it was used to launch Bulgaria's first communications satellite for TV service provider Bulsatcom. The landing wasn't easy, though. Because the rocket had to push BulgariaSat-1 to such a high orbit, the first stage experienced more force and heat during reentry than any other Falcon 9, according to a tweet from SpaceX CEO Elon Musk. Musk even warned that there was a "good chance [the] rocket booster doesn't make it back." Shortly after the landing, though, Musk returned to Twitter to add that the rocket booster used "almost all of the emergency crush core," which helps soften the landing.Read Replies (0)
