GitHub's annual report on its user community "combined telemetry data from over four million repositories with direct survey from over 12,000 developers to identify current trends among software development companies and open-source projects," reports InfoQ.

ZDNet notes the data shows that remote developers "aren't planning to go back to the office." Before the pandemic, only 41% of developers worked at an office either full-time or part-time, but of the 12,000 surveyed in GitHub's 2021 State of the Octoverse report, just 10.7% expect to go back to the office after the pandemic ends... Pre-pandemic, 28.1% of developers had hybrid arrangements but after the pandemic, 47.8% expect some hybrid arrangements. Before the pandemic, 26.5% worked in places where all workers were remote. Now, 38.8% expect to be fully remote.
ZDNet also highlighted some other general statistics: GitHub says it now has 73 million developer users and that it gained 16 million new users in 2021. Users created 61 million new repositories and there were 170 million pull requests that got merged into projects... One of the biggest projects on GitHub is the container software Docker, which has a whopping 632,000 contributors from 215 countries and consists of 49,593 packages.
That's more than a magnitude larger than the estimated number of Linux contributors — and implies that for every 117 developers now on GitHub, there was one who contributed to Docker.

Meanwhile, 2021's most popular language rankings for GitHub are the same as 2020, with one exception: Shell has risen one position to become the 8th most popular language, edging out C (which now ranks as the 9th most popular language).

And InfoQ summarized some other interesting statistics from GitHub's report:

• Good, reliable, and up-to-date documentation can boost productivity by 50%.

• Documentation is often under-invested.

• The number of pull requests merged within the workday goes down by 17% with each additional reviewer.

The U.S. General Services Administration said Friday that the Defense Department has solicited bids from Amazon, Google, Microsoft and Oracle for cloud contracts. From a report: The outreach comes after the Pentagon set aside a highly contested $10 billion contract that Microsoft had won and Amazon had challenged. The value of the new contracts is not known, but the Defense Department estimates it could run into the multiple billions of dollars. The new effort, known as Joint Warfighting Cloud Capability, or JWCC, appears like it will bolster the top global cloud infrastructure providers, Amazon and Microsoft, although it could also provide more credibility to two smaller entities.

"The Government anticipates awarding two IDIQ contracts -- one to Amazon Web Services (AWS) and one to Microsoft Corporation (Microsoft) -- but intends to award to all Cloud Service Providers (CSPs) that demonstrate the capability to meet DoD's requirements," the GSA said in its announcement. An indefinite delivery, indefinite quantity, or IDIQ, contract includes an indefinite amount of services for a specific period of time.

Drinking coffee or tea may be linked with a lower risk of stroke and dementia, according to the largest study of its kind. The Guardian reports: Strokes cause 10% of deaths globally, while dementia is one of the world's biggest health challenges -- 130 million are expected to be living with it by 2050. In the research, 365,000 people aged between 50 and 74 were followed for more than a decade. At the start the participants, who were involved in the UK Biobank study, self-reported how much coffee and tea they drank. Over the research period, 5,079 of them developed dementia and 10,053 went on to have at least one stroke.

Researchers found that people who drank two to three cups of coffee or three to five cups of tea a day, or a combination of four to six cups of coffee and tea, had the lowest risk of stroke or dementia. Those who drank two to three cups of coffee and two to three cups of tea daily had a 32% lower risk of stroke. These people had a 28% lower risk of dementia compared with those who did not drink tea or coffee. The research, by Yuan Zhang and colleagues from Tianjin Medical University, China, suggests drinking coffee alone or in combination with tea is also linked with lower risk of post-stroke dementia. "[W]hat generally happened is that the risk of stroke or dementia was lower in people who drank reasonably small amounts of coffee or tea compared to those who drank none at all, but that after a certain level of consumption, the risk started to increase again until it became higher than the risk to people who drank none," said professor Kevin McConway, an emeritus professor of applied statistics at the Open University who was not involved in the study.

"Once the coffee consumption got up to seven or eight cups a day, the stroke risk was greater than for people who drank no coffee, and quite a lot higher than for those who drank two or three cups a day."

The study has been published in the journal PLOS Medicine.

Going into the Hour of Code in 2018, Microsoft boasted that 100+ million Minecraft Hour of Code tutorials had already been logged by students.

In this year's Hour of Code: TimeCraft tutorial, kids will "learn basic coding concepts to correct mysterious mishaps throughout history!" An accompanying one-size-fits-all lesson plan for ages 6-18 instructs students to: "Experience a choose-your-own-adventure game, exploring key moments in human achievement. Using your coding superpowers, save the future by solving mysterious mishaps in time." Among other things, the coding challenges have K-12 students travel back in time to save Jazz from a kazoo future, prevent the Great Pyramids from being built as cubes, save the Great Wall of China from destruction by pandas, and wipe the frown off of the Mona Lisa. New this year, Microsoft notes, is that educators can sign up to have a Microsoft Education Expert lead their classroom through an Hour of Code lesson with Minecraft, thanks to the magic of Microsoft Teams Live Events.

On November 8, Microsoft made generally available to users worldwide its latest versions of Visual Studio and .NET. Users can download Visual Studio 2022 and .NET 6 starting today. From a report: Visual Studio 2022 is the first release of a 64-bit version of Visual Studio. By making Visual Studio 64-bit, officials said that they expect the release to better use all system resources, especially when working with more complex solutions over longer periods. According to Microsoft, during early VS 2022 testing, customers were able to run the VS IDE for days, even with solutions containing 700 or more projects.

Visual Studio 2022 also includes a number of edits and debug improvements. It also provides Hot Reload, which allows developers to edit their source code while their apps are running in Visual Studio 2022 and from the .NET CLI. , It also has Live Preview capabilities and cross-platform testing on Linux, among other new and improved features. Visual Studio 2022 is available for immediate download. The release notes for Visual Studio 2022 v.17 are here.

So apparently three Stanford professors are offering some tough-love to young people in the tech community. Mehran Sahami first worked at Google when it was still a startup (recruited to the company by Sergey Brin). Currently a Stanford CS professor, Sahami explained in 2019 that "I want students who engage in the endeavor of building technology to think more broadly about what are the implications of the things that they're developing — how do they impact other people? I think we'll all be better off."

Now Sahami has teamed up with two more Stanford professors to write a book calling for "a mature reckoning with the realization that the powerful technologies dominating our lives encode within them a set of values that we had no role in choosing and that we often do not even see..."

At a virtual event at Silicon Valley's Computer History Museum, the three professors discussed their new book, System Error: Where Big Tech Went Wrong and How We Can Reboot — and thoughtfully and succinctly distilled their basic argument. "The System Error that we're describing is a function of an optimization mindset that is embedded in computer science, and that's embedded in technology," says political scientist Jeremy Weinstein (one of the book's co-authors). "This mindset basically ignores the competing values that need to be 'refereed' as new products are designed. It's also embedded in the structure of the venture capital industry that's driving the growth of Silicon Valley and the growth of these companies, that prioritizes scale before we even understand anything about the impacts of technology in society. And of course it reflects the path that's been paved for these tech companies to market dominance by a government that's largely been in retreat from exercising any oversight."

Sahami thinks our technological landscape should have a protective infrastructure like the one regulating our roads and highways. "It's not a free-for all where the ultimate policy is 'If you were worried about driving safely then don't drive.'" Instead there's lanes and traffic lights and speed bumps — an entire safe-driving infrastructure which arrived through regulation." Or (as their political science professor/co-author Rob Reich tells the site), "Massive system problems should not be framed as choices that can be made by individual consumers."

Sahami also thinks breaking up big tech monopolies would just leaves smaller "less equipped" companies to deal with the same problems — but that positive changes in behavior might instead come from government scrutiny. But Reich also wants to see professional ethics (like the kind that are well-established in biomedical fields). "In the book we point the way forward on a number of different fronts about how to accelerate that..."

And he argues that at colleges, just one computing-ethics class isn't enough. "Ethics must be embedded through the entire curriculum."

ZDNet reports: JavaScript is now used by more than 16.4 million developers globally, says a survey of more than 19,000 coders — making it the world's most popular programming language "by a wide margin".

SlashData's 21st State of the Developer Nation Report examined global software developer trends across 160 countries during Q3 2021, covering programming languages, tools, APIs, apps and technology segments, as well as attitudes of developers themselves... While not necessarily a surprise in itself — JavaScript has, after all, been the world's most-used language for a number of years now — SlashData found that upwards of 2.5 million developers had joined the JavaScript community in the past six months alone. That's the same as the entire user base of Swift; or, the combined communities of Rust and Ruby.

The data for JavaScript also included language derivatives TypeScript and CoffeeScript.

Python might not be a close second, but its popularity is impressive nonetheless: according to SlashData, the language is now used by some 11.3 million coders, primarily within data science and machine learning, and IoT applications. The brainchild of Guido van Rossum, Python's popularity has exploded in recent years, overtaking that of Java, which is currently used by 9.6m developers. Java remains a go-to for mobile and desktop apps, SlashData's survey found. According to SlashData, Python added 2.3m developers to its community in the past 12 months. "That's a 25% growth rate, one of the highest across all the large programming language communities of more than 7M users," the report noted.

"The rise of data science and machine learning (ML) is a clear factor in Python's popularity. More than 70% of ML developers and data scientists report using Python. For perspective, only 17% use R, the other language often associated with data science."
The survey concluded these are, in order, the 10 most popular programming languages:

1. JavaScript
2. Python
3. Java
4. C/C++ [Yes, it lumps them together]
5. PHP
6. C#
7. "Visual development tools"
8. Kotlin
9. Swift
10. Go

The report also found that Rust, although coming in at #14, grew faster than any other language in the past 24 months, "nearly tripling in size from just 0.4M developers in Q3 2019 to 1.1M."

"It has never been more difficult to be a software developer than it is today," says Nigel Simpson, a former director of enterprise technology strategy at Walt Disney.

And they're not the only one who thinks so, writes the U.K. Group editor of InfoWorld: "Complexity kills," Lotus Notes creator and Microsoft veteran Ray Ozzie famously wrote in a 2005 internal memo. "It sucks the life out of developers; it makes products difficult to plan, build, and test; it introduces security challenges; and it causes user and administrator frustration."

If Ozzie thought things were complicated back then, you can't help but wonder what he would make of the complexity software developers face in the cloud-native era. The shift from building applications in a monolithic architecture hosted on a server you could go and touch, to breaking them down into multiple microservices, packaged up into containers, orchestrated with Kubernetes, and hosted in a distributed cloud environment, marks a clear jump in the level of complexity of our software. Add to that expectations of feature-rich, consumer-grade experiences, which are secure and resilient by design, and never has more been asked of developers. "There is a clear increase in complexity when you move to such a pervasive microservices environment," said Amazon CTO Werner Vogels during the AWS Summit in 2019. "Was it easier in the days when everything was in a monolith? Yes, for some parts definitely."

Or, as his colleague, head of devops product marketing at AWS, Emily Freeman, said in 2021, modern software development is "a study in entropy, and it is not getting any more simple."

On the other hand, complex technologies have never been easier to consume off the shelf, often through a single API — from basic libraries and frameworks, to image recognition capabilities or even whole payments stacks. Simply assemble and build your business logic on top. But is it really that simple?
The article also cites a critical 2020 blog post by RedMonk analyst Stephen O'Grady. "The process of application development is simply too fragmented at this point," O'Grady wrote. "The days of every enterprise architecture being three-tier, every database being relational, and every business application being written in Java and deployed to an application server are over.

"The single most defining characteristic of today's infrastructure is that there is no single defining characteristic. It's diverse to a fault."

An anonymous reader quotes a report from ZDNet: LFX supports projects and empowers open source teams by enabling them to write better, more secure code, drive engagement, and grow sustainable software ecosystems," the Linux Foundation says. Now, to address the growing threat of software supply chain attacks, the foundation is upgrading its LFX Security module to deal with these attacks. Jim Zemlin, the Linux Foundation's executive director, announced this new tooling today at the Linux Foundation Membership Summit.

Enhanced and free to use, LFX Security makes it easier for open source projects to secure their code. Specifically, the LFX Security module now includes automatic scanning for secrets-in-code and non-inclusive language, adding to its existing automated vulnerability detection capabilities. Software security firm BluBracket is contributing this functionality to the LFX as part of its mission to make software safer and more secure. This functionality builds on contributions from open source developer security company Snyk, helping make LFX the leading vulnerability detection platform for the open source community. [...] LFX Security will be further scaled out in 2022, helping to solve challenges for hundreds of thousands of critical open source projects under the Open Source Security Foundation. LFX Security is free and available now.

theodp writes: Chicago Public School (CPS) teachers were 'blindsided' after access to popular classroom software was yanked due to CPS's interpretation of Illinois' Student Online Personal Protection Act (SOPPA), the Chicago Sun-Times reports. Sneha Dey writes, "Among the software products that violate the law, CPS now says, are programs like Code.org, which is widely used in computer science classes, and Adobe applications used for artistic design and newspaper page layouts. That left has many high school newspapers unable to produce their print editions. Also off limits is Scratch, software to create interactive stores, animations and games. CPS had partnered with the Scratch Foundation to hold family coding nights, among other events."

The Blueprint's Karen Buecking has more on how the new student data protection law has upended the computer science curriculum at CPS, noting that CPS teachers received an email from tech-backed Code.org explaining the situation: "We've already signed student data protection agreements with over 150 districts across the state to comply with the new law," said the Code.org representative. "The bad news is CPS's agreement and application process contains onerous requirements unrelated to student privacy that make it prohibitive for organizations like Code.org to agree to CPS's requirements as written."

The Oracle JDK "is available free of charge for production use again," reports InfoQ, under a new "Oracle No-Fee Terms and Conditions" license.

The move, announced in mid-September, "reverses a 2018 decision to charge for Oracle JDK production use and does not affect Oracle's OpenJDK distribution," they write, noting that the new license "applies to the recently released version 17 of Oracle JDK and future versions." Donald Smith, Senior Director of Product Management at Oracle, explained the reason for this decision in a recent blog post, writing:

"Providing Oracle OpenJDK builds under the GPL was highly welcomed, but feedback from developers, academia, and enterprises was that they wanted the trusted, rock-solid Oracle JDK under an unambiguously free terms license, too. Oracle appreciates the feedback from the developer ecosystem and are pleased to announce that as of Java 17 we are delivering on exactly that request."

Smith explicitly stated that the No-Fee Terms and Conditions license "includes commercial and production use" [although the license does not seem to highlight this fact] and stated that "redistribution is permitted as long as it is not for a fee."

Abstract of a paper written by Michael Navarrete of University of Maryland: The United States experienced an unprecedented increase in unemployment insurance (UI) claims starting in March 2020, mainly due to layoffs caused by COVID-19. State unemployment insurance systems were inadequately prepared to process these claims. Those states using an antiquated programming language, COBOL, to process UI claims experienced longer delays in benefit disbursement. Using daily card consumption data from Affinity Solutions, I employ a two-way fixed effects estimator to measure the causal impact of COBOL-induced delays in UI benefits on aggregate consumption. The delays caused a 4.4 percentage point relative decline in total card consumption in COBOL states relative to non-COBOL states. Performing a back-of-the-envelope calculation using 2019 data, I find that real GDP declined by $181 billion (in 2012 dollars).

An indie developer has found an interesting observation: Though only 5.8% of his game's buyers were playing on Linux, they generated over 38% of the bug reports. Not because the Linux platform was buggier, either. Only 3 of the roughly 400 bug reports submitted by Linux users were platform specific, that is, would only happen on Linux. PC Gamer reports: The developer, posting as Koderski for developer Kodera Software on Reddit, makes indie game [Delta] V: Rings of Saturn -- that's Delta V, or DV, for the non-rocket-science-literate. [...] Koderski says he's sold a little over 12,000 copies of his game, and about 700 of those were bought by Linux players. "I got 1040 bug reports in total, out of which roughly 400 are made by Linux players," says Koderski's post. "That's one report per 11.5 users on average, and one report per 1.75 Linux players. That's right, an average Linux player will get you 650% more bug reports." Koderski's numbers are a limited sample size drawn from one person's experience, but tell a compelling story.

Koderski also says that very few of those bugs were specific to Linux, being clear that "This 5.8% of players found 38% of all the bugs that affected everyone." The bug reports themselves were also pretty high quality, he said, including software and OS versions, logs, and steps for replication. Multiple commenters on the post chalked this up to the kind of people who use Linux: Software professionals, IT employees, and engineers who would already be familiar with official bug reporting processes. It's a strong theory as to why this might be, though the sheer passion that the gaming on Linux community has for anyone who supports their favorite hobby may be another.

"Microsoft is reversing a decision to remove a key feature from its upcoming .NET 6 release, after a public outcry from the open source community," reports the Verge.

"Microsoft angered the .NET open source community earlier this week by removing a key part of Hot Reload in the upcoming release of .NET 6, a feature that allows developers to modify source code while an app is running and immediately see the results." It's a feature many had been looking forward to using in Visual Studio Code and across multiple platforms, until Microsoft made a controversial last-minute decision to lock it to Visual Studio 2022 which is a paid product that's limited to Windows. Sources at Microsoft, speaking on condition of anonymity, told The Verge that the last-minute change was made by Julia Liuson, the head of Microsoft's developer division, and was a business-focused move.

Microsoft has now reversed the change following a backlash, and anger inside the company from many of Microsoft's own employees. "We made a mistake in executing on our decision and took longer than expected to respond back to the community," explains Scott Hunter, director of program management for .NET. Microsoft has now approved the community's pull request to re-enable this feature and it will be available in the final version of the .NET 6 SDK...

This eventful episode came after weeks of unrest in the .NET community over Microsoft's involvement in the .NET Foundation. The foundation was created in 2014 when Microsoft made .NET open source, and it's supposed to be an independent organization that exists to improve open source software development and collaboration for .NET.

"Bringing VS Code to the browser is the realization of the original vision for the product," Microsoft said in a blog post. "It is also the start of a completely new one. An ephemeral editor that is available to anyone with a browser and an internet connection is the foundation for a future where we can truly edit anything from anywhere."

Or, as Mike Melanson describes it in his "This Week in Programming" column, "Microsoft continued its march toward developer dominance this week with the launch of Visual Studio Code for the Web, a lightweight version of the company's highly popular (mostly) open source code editor..." Now, before you go getting too excited, VS Code for the Web isn't really a fully-functional version of VS Code running in the browser, as it has no backend to back it up, which means its primary purpose is for client-side HTML, JavaScript, and CSS applications... VS Code for the Web is able to provide syntax colorization, text-based completions and other such features for popular languages such as C/C++, C#, Java, PHP, Rust, and Go, while TypeScript, JavaScript, and Python are "all powered by language services that run natively in the browser" and therefore provide a "better" experience, while those aforementioned Web languages, such as JSON, HTML, CSS, and LESS, will provide the best experience. Extensions, meanwhile — which are among the top reasons for using VS Code — generally work for user interface customizations (and can be synced with your other environments), but, again, not so much for those back-end features.

Caveats aside, VS Code for the Web does, indeed, offer a lightweight, available-anywhere code editor for things like your tablet, your Chromebook, and heck, even your XBOX...

While companies like Amazon and Google seem to be sitting idly by in this arena, Microsoft is not the only company focused on providing remote developer experiences. The Eclipse Foundation, for example, last year offered what it said was "a true open source alternative to Visual Studio Code" with Eclipse Theia, and Eclipse Foundation executive director Mike Milinkovich said he expects this to be just the beginning. "We have been saying for years that the future of developer tools is the browser. Developers already use their browsers for the vast majority of their day-to-day tasks, with code editing being amongst the last to move," Milinkovich wrote in an email. "Microsoft's recent vscode.dev announcement is a recognition of this trend. I expect that every serious cloud vendor will be following suit over the next few quarters."

GitPod, meanwhile, has been hard at work in this very same arena, with its own launch just last month of the open source OpenVSCode Server, which also lets developers run upstream Visual Studio Code in the browser.
Gitpod co-founder Johannes Landgraf calls it "yet another validation that we reached a tipping point of how and where we develop software" — but also more. "Think orchestration and provisioning of compute, operating system, language servers and all other tools you require for professional software development in the cloud."

Melanson's column also argues VS Code for the Web is meant to entice geeks further into the Microsoft development universe. "The next thing you know, you've spent $100 on other things...like GitHub Codespaces, which is, after all, pretty much the same exact thing, except it provides all those back-end services and, more importantly for Microsoft, is not free to use. And more important still, once you've got all those developers fully hooked on VS Code, Codespaces, GitHub, and the rest of it, Azure isn't too far down the line now, is it?"

TechCrunch's Sarah Perez writes about the new set of App Store Guidelines that Apple introduced today: One of the changes is the result of a previously announced settlement agreement with a class of U.S. app developers. It clarifies that developers are allowed to communicate with their customers about other payment methods available outside their app. Related to this, another new guideline explains that apps may request customer information like name and email, but the request must be optional for the user and shouldn't prevent them from using the app. The third guideline is unrelated to legal action, and simply details how developers can use a new App Store feature, called in-app events, which rolls out next week.

Specifically, Apple deleted a clause from guideline 3.1.3 which had previously said developers were not permitted to use information obtained within their app to target individual users outside of the app to use purchasing methods other than Apple's own in-app purchases. The old rule had also said this would include sending out emails to the address on file obtained when the customer signed up for the app. With this clause gone, developers are no longer barred from those sorts of communications. Apple also added a new section to guideline 5.1.1 (x) which explains further how developers may go about requesting user contact information. It says: "Apps may request basic contact information (such as name and email address) so long as the request is optional for the user, features and services are not conditional on providing the information, and it complies with all other provisions of these guidelines, including limitations on collecting information from kids."

Intel has open-sourced ControlFlag , a tool that uses machine learning to detect problems in computer code -- ideally to reduce the time required to debug apps and software. From a report: In tests, the company's machine programming research team says that ControlFlag has found hundreds of defects in proprietary, "production-quality" software, demonstrating its usefulness. "Last year, ControlFlag identified a code anomaly in Client URL (cURL), a computer software project transferring data using various network protocols over one billion times a day," Intel principal AI scientist Justin Gottschlich wrote in a blog post on LinkedIn.

"Most recently, ControlFlag achieved state-of-the-art results by identifying hundreds of latent defects related to memory and potential system crash bugs in proprietary production-level software. In addition, ControlFlag found dozens of novel anomalies on several high-quality open-source software repositories." The demand for quality code draws an ever-growing number of aspiring programmers to the profession. After years of study, they learn to translate abstracts into concrete, executable programs -- but most spend the majority of their working hours not programming. A recent study found that the IT industry spent an estimated $2 trillion in 2020 in software development costs associated with debugging code, with an estimated 50% of IT budgets spent on debugging.

Akamai researchers have analyzed 10,000 JavaScript samples including malware droppers, phishing pages, scamming tools, Magecart snippets, cryptominers, etc. At least 26% of them use some form of obfuscation to evade detection, indicating an uptick in the adoption of this basic yet effective technique. BleepingComputer reports: Obfuscation is when easy-to-understand source code is converted into a hard to understand and confusing code that still operates as intended. Threat actors commonly use obfuscation to make it harder to analyze malicious scripts and to bypass security software. Obfuscation can be achieved through various means like the injection of unused code into a script, the splitting and concatenating of the code (breaking it into unconnected chunks), or the use of hexadecimal patterns and tricky overlaps with function and variable naming.

But not all obfuscation is malicious or tricky. As the report explains, about 0.5% of the 20,000 top-ranking websites on the web (according to Alexa), also use obfuscation techniques. As such, detecting malicious code based on the fact that is obfuscated isn't enough on its own, and further correlation with malicious functionality needs to be made. This mixing with legitimate deployment is precisely what makes the detection of risky code challenging, and the reason why obfuscation is becoming so widespread in the threat landscape.

"One of Python's long-standing weaknesses, its inability to scale well in multithreaded environments, is the target of a new proposal among the core developers of the popular programming language," reports InfoWorld: Developer Sam Gross has proposed a major change to the Global Interpreter Lock, or GIL — a key component in CPython, the reference implementation of Python. If accepted, Gross's proposal would rewrite the way Python serializes access to objects in its runtime from multiple threads, and would boost multithreaded performance significantly... The new proposal makes changes to the way reference counting works for Python objects, so that references from the thread that owns an object are handled differently from those coming from other threads.

The overall effect of this change, and a number of others with it, actually boosts single-threaded performance slightly — by around 10%, according to some benchmarks performed on a forked version of the interpreter versus the mainline CPython 3.9 interpreter. Multithreaded performance, on some benchmarks, scales almost linearly with each new thread in the best case — e.g., when using 20 threads, an 18.1x speedup on one benchmark and a 19.8x speedup on another.
