Security researcher David Buchanan has found that Twitter image uploads can be polyglot files, meaning they can be valid simultaneously in multiple formats, such as a .jpg, a .rar archive and a .zip archive. From a report: Using some Python code he wrote, he created a thumbnail image of William Shakespeare overlaid with the words, "Unzip Me" and posted it to Twitter. The .jpg image is also a valid .zip file, so if you download it, you can unzip it and extract the contents, a multipart .rar archive of the text of Shakespeare's plays. [...] Twitter performs some processing on uploaded images, which has the potential to mess with the data. But Buchanan found that his multi-format file survived this process. It may be that image itself (excluding the rather bulky metadata) is light enough not to trigger any compression or post-upload processing.

Donald Fischer, who served as a product manager for Red Hat Enterprise Linux during its creation and early years of growth, writes: Red Hat saw, earlier than most, that the ascendance of open source made the need to pay for code go away, but the need for support and maintenance grew larger than ever. Thus Red Hat was never in the business of selling software, rather it was in the business of addressing the practical challenges that have always come along for the ride with software. [...] As an open source developer, you created that software. You can keep your package secure, legally documented, and maintained; who could possibly do it better? So why does Red Hat make the fat profits, and not you? Unfortunately, doing business with large companies requires a lot of bureaucratic toil. That's doubly true for organizations that require security, legal, and operational standards for every product they bring in the door. Working with these organizations requires a sales and marketing team, a customer support organization, a finance back-office, and lots of other "business stuff" in addition to technology. Red Hat has had that stuff, but you haven't.

And just like you don't have time to sell to large companies, they don't have time to buy from you alongside a thousand other open source creators, one at a time. Sure, big companies know how to install and use your software. (And good news! They already do.) But they can't afford to put each of 1100 npm packages through a procurement process that costs $20k per iteration. Red Hat solved this problem for one corner of open source by collecting 2,000+ open source projects together, adding assurances on top, and selling it as one subscription product. That worked for them, to the tune of billions. But did you get paid for your contributions?

Jeffrey M. Perkel, writing for Nature: Perched atop the Cerro Pachon ridge in the Chilean Andes is a building site that will eventually become the Large Synoptic Survey Telescope (LSST). When it comes online in 2022, the telescope will generate terabytes of data each night as it surveys the southern skies automatically. And to crunch those data, astronomers will use a familiar and increasingly popular tool: the Jupyter notebook. Jupyter is a free, open-source, interactive web tool known as a computational notebook, which researchers can use to combine software code, computational output, explanatory text and multimedia resources in a single document. Computational notebooks have been around for decades, but Jupyter in particular has exploded in popularity over the past couple of years. This rapid uptake has been aided by an enthusiastic community of user-developers and a redesigned architecture that allows the notebook to speak dozens of programming languages -- a fact reflected in its name, which was inspired, according to co-founder Fernando Perez, by the programming languages Julia (Ju), Python (Py) and R.

[...] For data scientists, Jupyter has emerged as a de facto standard, says Lorena Barba, a mechanical and aeronautical engineer at George Washington University in Washington DC. Mario Juric, an astronomer at the University of Washington in Seattle who coordinates the LSST's data-management team, says: "I've never seen any migration this fast. It's just amazing." Computational notebooks are essentially laboratory notebooks for scientific computing. Instead of pasting, say, DNA gels alongside lab protocols, researchers embed code, data and text to document their computational methods. The result, says Jupyter co-creator Brian Granger at California Polytechnic State University in San Luis Obispo, is a "computational narrative" -- a document that allows researchers to supplement their code and data with analysis, hypotheses and conjecture. For data scientists, that format can drive exploration.

An anonymous reader writes: A software security engineer has identified 12 Python libraries uploaded on the official Python Package Index (PyPI) that contained malicious code. The 12 packages used typo-squatting in the hopes a user would install them by accident or carelessness when doing a "pip install" operation for a mistyped more popular package, like Django (ex: diango).

Eleven libraries would attempt to either collect data about each infected environment, obtain boot persistence, or even open a reverse shell on remote workstations. A twelfth package, named "colourama," was financially-motivated and hijacked an infected users' operating system clipboard, where it would scan every 500ms for a Bitcoin address-like string, which it would replace with the attacker's own Bitcoin address in an attempt to hijack Bitcoin payments/transfers made by an infected user.
54 users downloaded that package -- although all 12 malicious packages have since been taken down.

Four of the packages were misspellings of django -- diango, djago, dajngo, and djanga.

"In 2012, most CS teacher professional development was paid for by the National Science Foundation or Google." And in the years that followed, 80,000 primary and secondary school teachers received opportunities to learn how to teach computer science without paying any fees -- thanks to tech-bankrolled Code.org.

But is anyone taking the classes? Slashdot reader theodp quotes a Communications of the ACM post by University of Michigan professor Mark Guzdial: In 2013, Code.org began, and they changed the face of CS education in the United States . It started out as just a video (linked here, seen over 14 million times), and grew into an organization that created and provided curriculum, offered teacher professional development, and worked with states and districts around public policy initiatives. A recent report from Code.org showed that 44 states have enacted public policies to promote computing education in the five years from 2013 to 2018, and much of that happened through Code.org's influence....

Now, Code.org has announced that they are starting to scale back their funding, which begins a multi-year transition to shift the burden of paying for teacher professional development to the local regions.... The only question is whether it's too soon. Will local regions step up and demonstrate that they value computer science by paying for it...? I'd guess that many states have between 40% and 70% of their high schools now offering computer science. However, even though many schools offer computer science, there are still few students taking computer science.
Indiana reported that only 0.4% of Indiana high school students had enrolled in their most popular course. Meanwhile in one region in Texas, 54 of 159 high schools offer computer science, yet only 2.3% of their students have ever taken a computer science class. But of course, there's another issue.

"If Code.org (or NSF or Google) are paying for all the development of CS teachers, then the districts don't get to say, 'In our community we care about this and we care less about that.' The U.S. education system is organized around the local regions calling the shots, setting the priorities, and deciding what they want teachers to teach."

Microsoft has official closed its acquisition of GitHub, the Git-based code sharing and collaboration service with 31 million developers. "The Redmond, WA-based software behemoth first said it would acquire GitHub for $7.5 billion in stock in June of this year, and after the acquisition closed it would continue to run it as an independent platform and business," reports TechCrunch. From the report: The acquisition is yet another sign of how Microsoft has been doubling down on courting developers and presenting itself as a neutral partner to help them with their projects. That is because, despite its own very profitable proprietary software business, Microsoft also has a number of other businesses -- for example, Azure, which competes with AWS and Google Cloud -- that rely heavily on it being unbiased towards one platform or another. And GitHub, Microsoft hopes, will be another signal to the community of that position. In that regard, it will be an interesting credibility test for the companies. Nat Friedman, previously the CEO of Xamarin, will be the CEO of GitHub on Monday. He says the site will be run as an independent platform and business.

"We will always support developers in their choice of any language, license, tool, platform, or cloud," he writes, noting that there will be more tools to come. "We will continue to build tasteful, snappy, polished tools that developers love," he added.

An anonymous reader quotes a report from Quartz: If you haven't heard, universities around the world are offering their courses online for free (or at least partially free). These courses are collectively called MOOCs or Massive Open Online Courses. In the past six years or so, over 800 universities have created more than 10,000 of these MOOCs. And I've been keeping track of these MOOCs the entire time over at Class Central, ever since they rose to prominence.

In the past four months alone, 190 universities have announced 600 such free online courses. I've compiled a list of them and categorized them according to the following subjects: Computer Science, Mathematics, Programming, Data Science, Humanities, Social Sciences, Education & Teaching, Health & Medicine, Business, Personal Development, Engineering, Art & Design, and finally Science. The full list is available in the report. If you need help signing up, there's a report for that too.

PolygamousRanchKid shares a report from 9to5Mac: At the Jamf Nation User Conference, IBM has announced that it is open sourcing its Mac@IBM provisioning code. The code being open-sourced offers IT departments the ability to gather additional information about their employees during macOS setup and allows employees to customize their enrollment by selecting apps or bundles of apps to install.

Back in 2015, IBM discussed how it went from zero to 30,000 Macs in six months. In 2016, IBM said Apple products were cheaper to manage when you looked at the entire life cycle: "IBM is saving a minimum of $265 (up to $535 depending on model) per Mac compared to a PC, over a 4-year lifespan. While the upfront workstation investment is lower for PCs, the residual value for Mac is higher The program's success has improved IBM's ability to attract and retain top talent -- a key advantage in today's competitive market."

Amazon is learning how hard it can be to move off of Oracle's database software. From a report: On Prime Day, while the e-retailer was dealing with a major website glitch that slowed sales, the company was also dealing with a technical problem in Ohio at one of its biggest warehouses, leading to thousands of delayed package deliveries, according to an internal report obtained by CNBC. The problem was in large part due to Amazon's migration from Oracle's database to its own technology, the documents show. The outage underscores the challenge Amazon faces as it looks to move completely off Oracle's database by 2020, and how difficult it is to re-create that level of reliability. It also shows that Oracle's database is more efficient in some aspects than Amazon's rival software, a point that Oracle will likely emphasize during this week's annual OpenWorld conference in San Francisco.

An anonymous reader writes: Undoubtedly in response to this politically motivated sort of claptrap, SQLite has released their own Code of Conduct. From the preamble:

Not everyone has found SQLite's attempt informative or funny (though many did). A developer wrote, for instance, "So is the SQLite CoC thing a joke or not? If it's not a joke, f*ck this. If it is a joke, that's even worse. Your CoC should be taken seriously." A security researcher, chimed in, "This sort of stunt will make actual code of conduct discussions harder. It's not funny, helpful, or wise."

Github engineers are trying to repair the data storage system underpinning the code hosting website, which has been presenting users with a "What!?" error for much of the Sunday. From a report: Depending on where you are, you may have been working on some Sunday evening programming, or getting up to speed with work on a Monday morning, using resources on GitHub.com -- and possibly failing miserably as a result of the outage. From about 4pm US West Coast time on Sunday, the website has been stuttering and spluttering. Specifically, the site is still up and serving pages -- it's just intermittently serving out-of-date files, and ignoring submitted Gists, bug reports, and posts. Sometimes, it appears to be serving a read-only cache or older backup of itself, although some fresh code pushes are coming through onto the site. From the status page, it appears a data storage system died, forcing the platform's engineers to move the dot-com's files over to another box. In the meantime, some older versions of files and repos are being served to visitors and users. "We're continuing to work on migrating a data storage system in order to restore access to GitHub.com," the team said just after 5pm PT, adding in the past few minutes: "We are continuing to repair a data storage system for GitHub.com. You may see inconsistent results during this process."

America's Multi-State Information Sharing & Analysis Center is operated in collaboration with its Department of Homeland Security's Office of Cybersecurity and Communications -- and they've got some bad news. MS-ISAC released an advisory warning government agencies, businesses, and home users of multiple high-risk security issues in PHP that can allow attackers to execute arbitrary code. Furthermore, if the PHP vulnerabilities are not successfully exploited, attackers could still induce a denial-of-service condition rendering the probed servers unusable... The PHP Group has issued fixes in the PHP 7.1.23 and 7.2.11 releases for all the high-risk bugs that could lead to DoS and arbitrary code execution in all vulnerable PHP 7.1 and 7.2 versions before these latest updates.
But meanwhile, Threatpost reported this week that 62% of the world's web sites are still running PHP version 5 -- even though its end of life is December 31st. "The deadlines will not be extended, and it is critical that PHP-based websites are upgraded to ensure that security support is provided," warned a recent CERT notice.

So far Drupal is the only CMS posting an official notice requiring upgrades to PHP 7 (by March, three months after the PHP 5.6's end of life deadline). Threatpost notes that "There has been no such notice from WordPress or Joomla."

An anonymous reader quotes Martin Monperrus, a professor of software at Stockholm's KTH Royal Institute of Technology: Repairnator is a bot. It constantly monitors software bugs discovered during continuous integration of open-source software and tries to fix them automatically. If it succeeds to synthesize a valid patch, Repairnator proposes the patch to the human developers, disguised under a fake human identity. To date, Repairnator has been able to produce 5 patches that were accepted by the human developers and permanently merged in the code base...

It analyzes bugs and produces patches, in the same way as human developers involved in software maintenance activities. This idea of a program repair bot is disruptive, because today humans are responsible for fixing bugs. In others words, we are talking about a bot meant to (partially) replace human developers for tedious tasks.... [F]or a patch to be human-competitive 1) the bot has to synthesize the patch faster than the human developer 2) the patch has to be judged good-enough by the human developer and permanently merged in the code base.... We believe that Repairnator prefigures a certain future of software development, where bots and humans will smoothly collaborate and even cooperate on software artifacts.
Their fake identity was a software engineer named Luc Esape, with a profile picture that "looks like a junior developer, eager to make open-source contributions... humans tend to have a priori biases against machines, and are more tolerant to errors if the contribution comes from a human peer. In the context of program repair, this means that developers may put the bar higher on the quality of the patch, if they know that the patch comes from a bot."

The researchers proudly published the approving comments on their merged patches -- although a conundrum arose when repairnator submitted a patch for Eclipse Ditto, only to be told that "We can only accept pull-requests which come from users who signed the Eclipse Foundation Contributor License Agreement."

"We were puzzled because a bot cannot physically or morally sign a license agreement and is probably not entitled to do so. Who owns the intellectual property and responsibility of a bot contribution: the robot operator, the bot implementer or the repair algorithm designer?"

An anonymous reader quotes TechCrunch: For the longest time, GitHub was all about storing source code and sharing it either with the rest of the world or your colleagues. Today, the company, which is in the process of being acquired by Microsoft, is taking a step in a different but related direction by launching GitHub Actions. Actions allow developers to not just host code on the platform but also run it. We're not talking about a new cloud to rival AWS here, but instead about something more akin to a very flexible IFTTT for developers who want to automate their development workflows, whether that is sending notifications or building a full continuous integration and delivery pipeline.

This is a big deal for GitHub. Indeed, Sam Lambert, GitHub's head of platform, described it to me as "the biggest shift we've had in the history of GitHub... I see Continuous Integration/Continuous Delivery as one narrow use case of actions. It's so, so much more," Lambert stressed. "And I think it's going to revolutionize DevOps because people are now going to build best in breed deployment workflows for specific applications and frameworks, and those become the de facto standard shared on GitHub... It's going to do everything we did for open source again for the DevOps space and for all those different parts of that workflow ecosystem...."

Over time -- and Lambert seemed to be in favor of this -- GitHub could also allow developers to sell their workflows and Actions through the GitHub marketplace. For now, that's not an option, but it it's definitely that's something the company has been thinking about. Lambert also noted that this could be a way for open source developers who don't want to build an enterprise version of their tools (and the sales force that goes with that) to monetize their efforts.

OpenSourceAllTheWay writes: There are many fantastic open-source tools out there for everything from scanning documents to making interactive music to creating 3D assets for games. Many of these tools have an Achilles heel though -- while the code quality is great and the tool is fully functional, the user interface (UI) and user experience (UX) are typically significantly inferior to what you get in competing commercial tools. In an nutshell, with open source, the code is great, the tool is free, there is no DRM/activation/telemetry bullshit involved in using the tool, but you very often get a weak UI/UX with the tool that -- unfortunately -- ultimately makes the tool far less of a joy to use daily than should be the case. A prime example would be the FOSS 3D tool Blender, which is great technically, but ultimately flops on its face because of a poorly designed UI that is a decade behind commercial 3D software. So here is the question: should open-source developer teams for larger FOSS projects include a professional UI/UX designer who does the UI for the project? There are many FOSS tools that would greatly benefit from a UI re-designed by a professional UI/UX designer.

MongoDB is taking action against cloud giants who are taking its open-source code and offering a hosted commercial version of its database to their users without playing by the open-source rules. The company announced today that it has issued a new software license, the Server Side Public License (SSPL), "that will apply to all new releases of its MongoDB Community Server, as well as all patch fixes for prior versions," reports TechCrunch. From the report: For virtually all regular users who are currently using the community server, nothing changes because the changes to the license don't apply to them. Instead, this is about what MongoDB sees as the misuse of the AGPLv3 license. "MongoDB was previously licensed under the GNU AGPLv3, which meant companies who wanted to run MongoDB as a publicly available service had to open source their software or obtain a commercial license from MongoDB," the company explains. "However, MongoDB's popularity has led some organizations to test the boundaries of the GNU AGPLv3."

So while the SSPL isn't all that different from the GNU GPLv3, with all the usual freedoms to use, modify and redistribute the code (and virtually the same language), the SSPL explicitly states that anybody who wants to offer MongoDB as a service -- or really any other software that uses this license -- needs to either get a commercial license or open source the service to give back the community. "The market is increasingly consuming software as a service, creating an incredible opportunity to foster a new wave of great open source server-side software. Unfortunately, once an open source project becomes interesting, it is too easy for cloud vendors who have not developed the software to capture all of the value but contribute nothing back to the community," said Eliot Horowitz, the CTO and co-founder of MongoDB, in a statement. "We have greatly contributed to -- and benefited from -- open source and we are in a unique position to lead on an issue impacting many organizations. We hope this will help inspire more projects and protect open source innovation."

At the company's first developer conference, Magic Leap announced they are opening orders of the Magic Leap One Creator's Edition headset to the 48 contiguous states of the USA. If you're in Hawaii or Alaska, no dice. TechCrunch reports: Previously, you had to be in Chicago, LA, Miami, NYC, San Francisco or Seattle in order to get your hands on it. Also, if you had previously ordered the headset in one of those cities, someone would come to you, drop it off and get you set up personally. That service is expanding to 50 cities, but you also don't need to have someone set it up for you in order to buy one now. It's worth reiterating that this thing costs $2,295. The company is doing a financing plan with Affirm so that interested buyers can spread the cost of the device over 24 months.

An anonymous reader quotes a report from The Verge: For months, Google has been trying to stay out of the way of the growing tech backlash, but yesterday, the dam finally broke with news of a bug in the rarely used Google+ network that exposed private information for as many as 500,000 users. Google found and fixed the bug back in March, around the same time the Cambridge Analytica story was heating up in earnest. [...] The vulnerability itself seems to have been relatively small in scope. The heart of the problem was a specific developer API that could be used to see non-public information. But crucially, there's no evidence that it actually was used to see private data, and given the thin user base, it's not clear how much non-public data there really was to see. The API was theoretically accessible to anyone who asked, but only 432 people actually applied for access (again, it's Google+), so it's plausible that none of them ever thought of using it this way.

The bigger problem for Google isn't the crime, but the cover-up. The vulnerability was fixed in March, but Google didn't come clean until seven months later when The Wall Street Journal got hold of some of the memos discussing the bug. [...] Part of the disconnect comes from the fact that, legally, Google is in the clear. There are lots of laws about reporting breaches -- primarily the GDPR but also a string of state-level bills -- but by that standard, what happened to Google+ wasn't technically a breach. Those laws are concerned with unauthorized access to user information, codifying the basic idea that if someone steals your credit card or phone number, you have a right to know about it. But Google just found that data was available to developers, not that any data was actually taken. With no clear data stolen, Google had no legal reporting requirements. As far as the lawyers were concerned, it wasn't a breach, and quietly fixing the problem was good enough.

The Internet Archive has launched a free, browser-based Commodore 64 Emulator with over 10,500 programs that are "working and tested for at least booting properly." Interestingly, the emulator comes just before the launch of Commodore's own C64 Mini. "It's based off the VICE emulator version 3.2, which is a triumph of engineering," adds HardOCP.

Economist Paul Romer, a co-winner of the 2018 Nobel Prize in economics, uses the programming language Python for his research, according to Quartz. Romer reportedly tried using Wolfram Mathematica to make his work transparent, but it didn't work so he converted to a Jupyter notebook instead. From the report: Romer believes in making research transparent. He argues that openness and clarity about methodology is important for scientific research to gain trust. As Romer explained in an April 2018 blog post, in an effort to make his own work transparent, he tried to use Mathematica to share one of his studies in a way that anyone could explore every detail of his data and methods. It didn't work. He says that Mathematica's owner, Wolfram Research, made it too difficult to share his work in a way that didn't require other people to use the proprietary software, too. Readers also could not see all of the code he used for his equations.

Instead of using Mathematica, Romer discovered that he could use a Jupyter notebook for sharing his research. Jupyter notebooks are web applications that allow programmers and researchers to share documents that include code, charts, equations, and data. Jupyter notebooks allow for code written in dozens of programming languages. For his research, Romer used Python -- the most popular language for data science and statistics. Importantly, unlike notebooks made from Mathematica, Jupyter notebooks are open source, which means that anyone can look at all of the code that created them. This allows for truly transparent research. In a compelling story for The Atlantic, James Somers argued that Jupyter notebooks may replace the traditional research paper typically shared as a PDF.
