I Programmer writes: December 1st is much anticipated among those who like programming puzzles. It is time to start collecting stars by solving small puzzles on the Advent of Code website with the goal of amassing 50 stars by Christmas Day, December 25th. Raku has also opened its advent calendar and there's a brand new Bekk Christmas blog with informational content on multiple topics... At the time of writing we are only 10.5 hours into Advent of Code's Day 1, almost 50,000 users have completed both puzzles and another 8,484 have completed the first. [Some programmers are even livestreaming their progress on Twitch, or sharing their thoughts (and some particuarly creative solutions) in the Advent of Code subreddit.]

We can credit Perl with pioneering the idea of a programming advent calendar with daily articles with a festive theme and the Raku Advent Calendar now continues the tradition. Now in its 13th year, but only the third with its new name this year's first advent post solves a problem faced by Santa of creating thumbnails of approaching 2 billion images...
Smashing magazine has pulled together its own exhaustive list of additional geek-themed advent calendars. Some of the other highlights:

• The beloved site "24 Pull Requests" has relaunched for 2021, daring participants to make 24 pull requests before December 24th. (The site's tagline is "giving back to open source for the holidays.") Over the years 26,465 contributors (as well as 25,738 organizations) have already participated through the site.

• The Advent of JavaScript and Advent of CSS sites promise 24 puzzles delivered by email (though you'll have to pay if you also want them to email you the solutions!)

• This year also saw daily challenges from the sixth annual Code Security advent calendar being announced on Twitter, while TryHackMe.com has its own set of cybersecurity puzzles (and even a few prizes).

On Monday JetBrains (creators of the Kotlin programming language and makers of the integrated development environment IntelliJ IDEA) made an announcement: a preview for a lightweight new multi-language IDE called Fleet using IntelliJ's code-processing engine with a distributed IDE architecture and a reimagined UI.

By Friday they'd received an "overwhelming" number of requests, and announced the preview program had stopped accepting new requests. ("To subscribe for updates and the public preview announcement at jetbrains.com/fleet or follow @JetBrains_Fleet on Twitter.")

They'd received 80,000 requests in just the first 30 hours, reports Visual Studio magazine: Although JetBrains didn't even mention VS Code in its Nov. 28 announcement, many media pundits immediately characterized it along the lines of an "answer to Visual Studio Code," a "response to Visual Studio Code," a "competitor to Visual Studio Code" and so on...

"When you first launch Fleet, it starts up as a full-fledged editor that provides syntax highlighting, simple code completion, and all the things you'd expect from an editor," JetBrains said. "But wait, there's more! Fleet is also a fully functional IDE bringing smart completion, refactorings, navigation, debugging, and everything else that you're used to having in an IDE — all with a single button click."
"It starts up in an instant so you can begin working immediately..." boasts the Fleet web page, adding that Fleet "is designed to automatically detect your project configuration from the source code, maximizing the value you get from its smart code-processing engine while minimizing the need to configure the project in the IDE." And it also offers "project and context aware code completion, navigation to definitions and usages, on-the-fly code quality checks, and quick-fixes..."

Fleet also offers a collaborative environment allowing developers to work together — not just sharing the editor, but also terminals and debugging sessions. (There's even a diff view for reviewing changes.) "Others can connect to a collaboration session you initiate on your machine, or everyone can connect to a shared remote dev environment," explains Fleet's web page. "It supports a number of remote work scenarios and can be run locally on the developer's computer, in the cloud, or on a remote server," reports SD Times. (And Fleet's home page says soon it will even run in Docker containers configured with an appropriate environment for your project.)

SD Times adds that Fleet "currently supports Java, Kotlin, Go, Python, Rust, and JavaScript. The company plans to extend support to cover PHP, C++, C#, and HTML, which are the remaining languages that have IntelliJ IDEs." It's multi-platform — running on Linux, MacOS, or Windows — and Fleet's web page promises "a familiar and consistent user experience" offering one IDE for the many different technologies you might end up using.

And yes, there's a dark theme.

Wikipedia co-founder Jimmy Wales is selling a non-fungible token (or NFT) based on his first edit of the free encyclopedia. From a report: Auction house Christie's will hold a sale of the token from December 3rd to 15th, auctioning it alongside the Strawberry iMac Wales was using around Wikipedia's launch. The funds will go toward charitable causes and WT.Social, a donation-backed social network that Wales launched in 2019. Wales' NFT is effectively the keys to a very early version of Wikipedia, which debuted in January of 2001.

"What you see displayed is what Wikipedia looked like at the moment that I set up the software," he tells The Verge. The single page will be launched publicly on the web, and much like Wikipedia itself, anyone will be able to see and edit it. But all changes will revert after five minutes, returning it to its original state: a single edit reading "Hello, World!" following a long-held tradition of programming. The NFT, which is written to the Ethereum blockchain, encodes a smart contract that grants its buyer control over that website. The buyer can change the window for reverting edits, and if they really want, they can turn off editing or shut down the page. They can also take a completely hands-off approach and let Wales manage the page for them.

How many members of your team are so irreplaceable that if they were hit by a bus, your project would grind to a halt?

For PHP, that number is: two. (According to a post by PHP contributor Joe Watkins earlier this year that's now being cited in Mike Melanson's "This Week in Programming" column.) "Maybe as few as two people would have to wake up this morning and decide they want to do something different with their lives in order for the PHP project to lack the expertise and resources to move it forward in its current form, and at current pace," Watkins wrote at the time, naming Dmitry Stogov and Nikita Popov as those two. Well, last week, Nikita Popov was thankfully not hit by a bus, but he did decide to move on from his role with PHP to instead focus his activities on LLVM.

Also thankfully, Watkins' article earlier this year opened some eyes to the situation at hand and, as he writes in a follow-up article this week, JetBrains (Popov's employer) reached out to him at the time regarding starting a PHP Foundation. This week, with Popov's departure, the PHP Foundation was officially launched with the goal of funding part/full-time developers to work on the PHP core in 2022. At launch, the PHP Foundation will count 10 companies — Automattic, Laravel, Acquia, Zend, Private Packagist, Symfony, Craft CMS, Tideways, PrestaShop, and JetBrains — among its backers, with an expectation to raise $300,000 per year, and with JetBrains contributing $100,000 annually. Alongside that, the foundation is being launched using foundation-as-a-service provider Open Collective, and just under 700 contributors have already raised more than $40,000 for the foundation.

One of the key benefits to creating a foundation, rather than sticking with the status quo, goes beyond increasing the bus factor — it diversifies the influences on PHP. Watkins points out that, for much of the history of PHP, Zend, the employer of Dmitry Stogov, has been a primary financial backer, and as such has had some amount of influence on the language's direction. Similarly, JetBrains had increased influence during its time employing Popov on PHP."To say they have not influenced the direction of the language as a whole would just not be true...." While Watkins says that everything has been above board and gone through standard processes to ensure so, influence is nonetheless indisputable, and that "The Foundation represents a new way to push the language forward..."

The current RFC process, JetBrains writes, "will not change, and language decisions will always be left to the PHP Internals community."
And in addition, Watkins adds, "It provides us the mechanism by which to raise the bus factor, so that we never face the problems we face today, and have faced in the past."

On Monday morning the moderation team for the Rust programming language "resigned effective immediately," reports The New Stack: The resignation was tendered via a pull request on GitHub, wherein team member Andrew Gallant wrote that the team resigned "in protest of the Core Team placing themselves unaccountable to anyone but themselves."

According to the page describing Rust governance, the moderation team's purpose is to do just that — to help "uphold the code of conduct and community standards" — and according to the resignation letter, they are unable to do so, with the Core Team seemingly being outside of those bounds. "As a result of such structural unaccountability, we have been unable to enforce the Rust Code of Conduct to the standards the community expects of us and to the standards we hold ourselves to," Gallant continues, before making four specific recommendations to the Rust community as to how to move forward.

First, Gallant writes that the Rust community should "come to a consensus on a process for oversight over the Core Team," which he says is currently "answerable only to themselves." Next, the outgoing team recommends that the "replacement for the Mod Team be made by Rust Team Members not on the Core Team," and that this future team "with advice from Rust Team Members, proactively decide how best to handle and discover unhealthy conflict among Rust Team Members," with "professional mediation" also suggested. The final point, which they say is unrelated, is that the next team should "take special care to keep the team of a healthy size and diversity, to the extent possible," something they failed to do themselves. To that point, the outgoing team is just three members, Andre Bogus, Andrew Gallant, and Matthieu M...

The former team concludes their resignation letter, writing that "we have avoided airing specific grievances beyond unaccountability" because they are choosing "to maintain discretion and confidentiality" and that the Rust community and their replacements "exercise extreme skepticism of any statements by the Core Team (or members thereof) claiming to illuminate the situation."
"Our relationship with Core has been deteriorating for months," they add in a thread on Reddit (where the subReddit's moderators have since locked out comments "in light of the volatile nature of this thread.")

There's just one more official update. Thursday former Rust moderation team member Andrew Gallant tweeted the URL to a new post which has now appeared on the "Inside Rust blog" — titled "In response to the moderation team resignation." The post reads: As top-level team leads, project directors to the Foundation, and core team members, we are actively collaborating to establish next steps after the statement from the Rust moderation team. While we are having ongoing conversations to share perspectives on the situation, we'd like to collectively state that we are all committed to the continuity and long term health of the project.

Updates on next steps will be shared with the project and wider community over the next few weeks. In the meantime, we are grateful to the interim moderators who have stepped up to provide moderation continuity to the project.

An anonymous reader quotes a report from The Next Web: YouTube's decision to hide dislike counts on videos has sparked anger and derision. One inventive programmer has attempted to restore the feature in a browser extension. The plugin currently uses the Google API to generate the dislike count. However, this functionality will be removed from December 13. "I'll try to scrape as much data as possible until then," the extension's creator said on Reddit. "After that -- total dislikes will be estimated using extension users as a sample."

The alpha version isn't perfect. It currently only works on videos for which the Youtube API returns a valid dislike count. The calculations could also be skewed by the userbase, which is unlikely to represent the average YouTube viewer. The developer said they're exploring ways to mitigate this, such as comparing the downvotes collected through the public of extension users to a cache of real downvotes. The results should also improve as uptake grows. The plugin could provide a useful service, but its greatest value may be as a potent symbol of protest. You can try it out here -- but proceed at your own risk. If you want to check out the code, it's been published on GitHub.

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.

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."

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."

"Virtually all compilers -- programs that transform human-readable source code into computer-executable machine code -- are vulnerable to an insidious attack in which an adversary can introduce targeted vulnerabilities into any software without being detected," warns cybersecurity expert Brian Krebs in a new report. An anonymous reader shares an excerpt: Researchers with the University of Cambridge discovered a bug that affects most computer code compilers and many software development environments. At issue is a component of the digital text encoding standard Unicode, which allows computers to exchange information regardless of the language used. Unicode currently defines more than 143,000 characters across 154 different language scripts (in addition to many non-script character sets, such as emojis). Specifically, the weakness involves Unicode's bi-directional or "Bidi" algorithm, which handles displaying text that includes mixed scripts with different display orders, such as Arabic -- which is read right to left -- and English (left to right). But computer systems need to have a deterministic way of resolving conflicting directionality in text. Enter the "Bidi override," which can be used to make left-to-right text read right-to-left, and vice versa.

"In some scenarios, the default ordering set by the Bidi Algorithm may not be sufficient," the Cambridge researchers wrote. "For these cases, Bidi override control characters enable switching the display ordering of groups of characters." Bidi overrides enable even single-script characters to be displayed in an order different from their logical encoding. As the researchers point out, this fact has previously been exploited to disguise the file extensions of malware disseminated via email. Here's the problem: Most programming languages let you put these Bidi overrides in comments and strings. This is bad because most programming languages allow comments within which all text -- including control characters -- is ignored by compilers and interpreters. Also, it's bad because most programming languages allow string literals that may contain arbitrary characters, including control characters.

"So you can use them in source code that appears innocuous to a human reviewer [that] can actually do something nasty," said Ross Anderson, a professor of computer security at Cambridge and co-author of the research. "That's bad news for projects like Linux and Webkit that accept contributions from random people, subject them to manual review, then incorporate them into critical code. This vulnerability is, as far as I know, the first one to affect almost everything." The research paper, which dubbed the vulnerability "Trojan Source," notes that while both comments and strings will have syntax-specific semantics indicating their start and end, these bounds are not respected by Bidi overrides. [...] Anderson said such an attack could be challenging for a human code reviewer to detect, as the rendered source code looks perfectly acceptable. "If the change in logic is subtle enough to go undetected in subsequent testing, an adversary could introduce targeted vulnerabilities without being detected," he said. Equally concerning is that Bidi override characters persist through the copy-and-paste functions on most modern browsers, editors, and operating systems.

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 anonymous reader shares a report: Leaked documents from company all-hands meetings in the summer of 2020 and January and February of this year, led by the school's now former chief operating officer, Molly Graham, who resigned earlier this month, and others led by its chief business officer, Matt Wyndowe, showed that Lambda School placed only 30% of its 2020 graduates in qualifying jobs during the first half of 2020. This figure is in stark contrast to the 74% placement rate it advertised for its 2019 graduates, the latest figure the school has made publicly available. In a tweet, Graham wrote that her mission was to "get the company through a pivotal phase" and position it to "operate well without me." These documents, given to Insider by a person familiar with the meetings, alongside over a dozen interviews with former Lambda School students and instructors, suggest that Graham is leaving with that mission far from accomplished.

Cofounded in 2017 by the tech entrepreneurs Austen Allred and Ben Nelson, with help from the startup accelerator Y Combinator, Lambda School offered a nontraditional path for those seeking careers in computer science. In lieu of a four-year degree, students could take a crash course in programming while paying no tuition up front; an income-share agreement allowed students to pay the school a portion of their salary after being hired in a tech job with an annual salary of at least $50,000. Blog posts advertised it as "incentive-aligned" education. With the global edtech industry worth more than $106 billion as of this year, schools have popped up across North America promising to teach students using a similar business model. Lambda School itself has raised a total of $122 million from venture capital. Lambda School enrolls thousands of students a year and has indicated it plans on growing many times over to give investors profitable returns on the investments they've made.

"Money may not grow on trees," argues InfoWorld, "but it does grow in GitHub repos." (as well as other open-source code-hosting sites). "Open source projects produce the most valuable and sophisticated software on the planet, free for the taking, dramatically lowering the costs of information technology for all companies..."

Then they picked out a few to recognize and honor with their 2021 Best of Open Source Software Awards.

The winners include:

• Windows Terminal, which they describe as a command-line terminal application with GPU-accelerated rendering giving "an order-of-magnitude performance boost over the older console host... Configuration options let you customize terminal appearance and behavior in ways never possible before."

• Crystal, "a project to deliver a programming language with the speed of C and the expressiveness of Ruby" which can interface with C code. (Version 1.0 was released this spring after years of development.)

• Flutter, Google's UI toolkit for generating natively-compiled mobile/web/desktop applications (based on Dart).

• Presto, an open source distributed SQL engine, and BlazingSQL, a GPU-accelerated SQL engine.

• Apache Superset (an enterprise-ready business intelligence web application offering easy dataset visualization) and Apache Solr, a search platform built on Apache Lucerne. ("Unlike Elasticsearch, which dropped its open source license, Solr is still free.")

"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?"

An anonymous reader quotes a report from Motherboard: In the early hours of Sunday morning, hackers took down the corporate servers and systems of Sinclair Broadcast Group, a giant U.S. TV conglomerate that owns or operates more than 600 channels across the country. Days later, inside the company, "it's pandemonium and chaos," as one current employee, who asked to remain anonymous as they were not authorized to speak to the press, told Motherboard. Sinclair has released very few details about the attack since it was hacked Sunday. On Wednesday, Bloomberg reported that the group behind the attack is the infamous Evil Corp., a ransomware gang that is believed to be based in Russia and which was sanctioned by the U.S. Treasury department in 2019.

The ransomware attack interfered with several channels' broadcast programming, preventing them from airing ads or NFL games, as reported by The Record, a news site owned by cybersecurity firm Recorded Future. It has also left employees confused and wondering what's going on, according to current Sinclair workers. "Whoever did this, they either by accident or by design did a very good job," a current employee said in a phone call, explaining that there are some channels that haven't been able to air commercials since Sunday. "We're really running in the blind [...] you really can't do your job." The employee said that he was working on Sunday and was able to get two emails out to colleagues. "And one of them got it, and the other one didn't," they said.

Employees did not have access to their emails until Tuesday morning, according to the two employees and text messages seen by Motherboard. The office computers, however, are still locked by the company out of precaution, and Sinclair told employees not to log into their corporate VPN, which they usually used to do their jobs. Until Thursday, the company was communicating with employees via text, according to the sources, who shared some of the texts sent by the company. In one of them, they called for an all hands meeting. The meeting, according to the two current employees, was quick and vague. Both sources said that the company should be more transparent with its own employees.

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.

The Food and Drug Administration approved a virtual reality-based treatment for children with the visual disorder amblyopia, or lazy eye, the company behind the therapy announced today. The Verge reports: Luminopia's approach uses TV and movies to develop the weaker eye and train the eyes to work together. Patients watch the show or movie through a headset that shows the images to each eye separately. The images shown to the stronger eye have a lower contrast, and the images are presented with overlays that force the brain to use both eyes to see them properly. Kids using the therapy and wearing glasses had more improvement in their vision than a similar group of kids who did not use the therapy and just wore corrective glasses full time during a clinical trial of the technology. After 12 weeks watching the shows one hour per day, six days per week, 62 percent of kids using the treatment had a strong improvement in their vision. Only around a third of the kids in the comparison group had similar improvements over the course of the 12 weeks.

Luminopia has over 700 hours of programming in its library, and it partnered with kids' content distributors like Nelvana and Sesame Workshop to develop the tool. The authors of the clinical trial wrote that they think that the option to pick popular videos might be one reason users stuck to the program -- people followed the treatment plan 88 percent of the time. Less than 50 percent of patients stick to eye patches or blurring drops. With the approval, Luminopia joins only a handful of companies with clearance to offer a digital therapeutic as a prescription treatment for medical conditions. Last year, the FDA approved a prescription video game called EndeavorRx, which treats ADHD in kids between eight and 12 years old. Luminopia said in a statement that it plans to launch the treatment in 2022.

"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.

Following a brief beta-testing period, Ubuntu 21.10 has finally become available to download in the "final" stable form. BetaNews: Code-named "Impish Indri," this version of Ubuntu is not a Long Term Support (LTS) version, so it is only supported for nine months. Ubuntu 21.10 features Linux kernel 5.13 and a Snap variant of the Mozilla Firefox browser. "Ubuntu 21.10 brings the all-new PHP 8 and GCC 11 including full support for static analysis, greatly improving everyday developer security awareness in low-level programming. With Gnome 40 desktop users gain dynamic workspaces and touchpad gestures. The new Firefox snap, published by Mozilla, improves security and guarantees access to both the latest and the extended support release versions of the browser. The exact same versions of the browser are available on multiple different versions of Ubuntu, simplifying enterprise developer platform management," says Canonical.
