A high school computer science teacher claims there's an "unacknowledged failure" of America's computer science (CS) classes at the high school and junior high school level. "Visit classrooms and you'll find students working with robotic sensors, writing games and animations in Scratch, interfacing with Arduino microcontrollers, constructing websites, and building apps with MIT App Inventor...

"Look underneath the celebratory and self-congratulatory remarks, however, and you'll find that, although contemporary secondary education is quite good at generating initial student interest, it has had much less success at sustaining that engagement beyond a few weeks or months, and has frankly been ineffectual in terms of (a) measurable learning for the majority of students; (b) boosting the number of students who take a second CS course, either in high school or college; and (c) adequately preparing students for CS college study."

Long-time Slashdot reader theodp writes: In " A New Pedagogy to Address the Unacknowledged Failure of American Secondary CS Education ," high school computer science teacher Scott Portnoff argues that a big part of the problem is the survey nature of today's most popular high school CS course offerings — Exploring Computer Science (ECS) and AP Computer Science Principles (AP CSP) — both of whose foundational premise is that programming is just one of many CS topics. "Up until a decade ago," Portnoff explains, "introductory high school computer science classes were synonymous with programming instruction, period. No longer."

This new status quo in secondary CS education, Portnoff argues, resulted from baseless speculation that programming was what made Java-based AP CS A inaccessible, opposed to, say, an uninspiring or pedagogically ineffective version of that particular curriculum, or a poorly prepared instructor. It's quite a departure from the 2011 CSTA K-12 Computer Science Standards, which made the case for the centrality of programming in CS education ("Pedagogically, computer programming has the same relation to studying computer science as playing an instrument does to studying music or painting does to studying art. In each case, even a small amount of hands-on experience adds immensely to life-long appreciation and understanding").
This teacher believes that programming languages are acquired rather than learned, just like any other human language — and concludes the solution is multi-year courses focused on one programming language until proficiency is fully acquired.

For this reason, for the last seven years he's also been making his students memorize small programs, and then type them out perfectly, arguing that "the brain subconsciously constructs an internal mental representation of the syntax rules implicitly by induction from the patterns in the data."

"Amazon Web Services on Wednesday launched Amazon Honeycode, a fully-managed service that enables companies to build mobile and web applications without any programming," reports ZDNet: Customers can use the service to build apps that leverage an AWS-built database, such as a simple task-tracking application or a more complex project management app to manage multiple workflows. "Customers have told us that the need for custom applications far outstrips the capacity of developers to create them," AWS VP Larry Augustin said in a statement.

Low-code and no-code tools have been growing in popularity in recent years, enabling people with little or no coding experience to be able to build the applications they need. Other major cloud companies like Salesforce offer low-code app builders. With IT teams stretched thin during the COVID-19 pandemic, low-code tools can prove particularly useful.
Customers "can get started by selecting a pre-built template, where the data model, business logic, and applications are pre-defined and ready-to-use..." Amazon explains in a press release. "Or, they can import data into a blank workbook, use the familiar spreadsheet interface to define the data model, and design the application screens with objects like lists, buttons, and input fields.

"Builders can also add automations to their applications to drive notifications, reminders, approvals, and other actions based on conditions. Once the application is built, customers simply click a button to share it with team members."

"A proposal under consideration by Python's development team would finally bring pattern matching statements to the language," reports InfoWorld: The creators of the Python language are mulling a new proposal, PEP 622, that would finally bring a pattern matching statement syntax to Python. The new pattern matching statements would give Python programmers more expressive ways of handling structured data, without having to resort to workarounds...

While Python has lacked a native syntax for pattern matching, it has been possible to emulate it with if/elif/else chains or a dictionary lookup. PEP 622 proposes a method for matching an expression against a number of kinds of patterns using a match/case syntax:

match something:

case 0 | 1 | 2:
print("Small number")

case [] | [_]:
print("A short sequence")

case str() | bytes():
print("Something string-like")

case _:
print("Something else")


Supported pattern match types include literals, names, constant values, sequences, a mapping (basically, the presence of a key-value pair in the expression), a class, a mixture of the above, or any of those plus conditional expressions. Any matches that are ambiguous or impossible to resolve will throw an exception at runtime... If an object implements the __match__ method, it can be used to test if it matches a given class pattern and return an appropriate response.
One of the authors of the new PEP was Python creator Guido van Rossum, according to the article -- and he'd drafted an earlier pattern matching proposal back in 2006 that was rejected (following the rejection of an earlier proposal in 2001).

The article also notes that many aspects of this PEP were inspired by the way pattern matching works in Rust and Scala.

Long-time Slashdot reader PCM2 shares a report from CBS News: Gov. Gavin Newsom on Thursday announced a new COVID-19 modeling website as well as new open-source tools designed to help California residents understand the data informing local health departments and empower what he called "citizen scientists." The governor introduced the new coronavirus modeling website [...] as a way for residents to see the raw data that is driving the decisions of state and county officials with full transparency.

The new website features three sections: a "Nowcast" section that provides the most current information on how fast COVID-19 is spreading in the state and by county; a "Forecasts" section that provides short-term COVID-19 forecasts in the state and by county; and a "Scenarios" section that projects the possible long-term impacts under different scenarios and responses to COVID-19, again for the whole state and by county. "We want to open up our site to 'netizen-tists' ... of citizen-scientists, people that are out there doing coding every single day," said Newsom. "We want to give them access through an open-source platform to all of the available data that we have, that I have, that our health professionals have, in a way that we don't believe has been done before anywhere in the United States. This is a deep dive for transparency and openness. This is a new resource that we are making available today."

Basecamp's Hey email app is now open to everyone after Apple "definitively approved" it for the App Store. No invite code is required for users to sign up. Engadget reports: Basecamp CTO and co-founder David Heinemeier Hansson tweeted the news today. Hey will not include any in-app purchases (IAP), so Apple will not get its standard 30 percent commission. At first, Apple objected to the fact that users would download the app from the App Store but have to sign up via the web. Apple's policies require that developers use IAP to unlock paid features or functionality in an app. Hey managed to skirt around those rules by offering a free trial option.

Hey is now open to everyone, and it does not require an invite code. The app promises a more organized approach to email, for $99 per year. But perhaps more importantly, Hey is an example of how developers can avoid paying Apple 30 percent of IAP and subscription fees. "Hopefully this paves an illuminated path for approval for other multi-platform SAAS applications as well. There are still a litany of antitrust questions to answer, but things legitimately got a little better. New policies, new precedence. Apple took a great step forward," Hansson tweeted.

Michael Hawley, a computer programmer, professor, musician, speechwriter and impresario who helped lay the intellectual groundwork for what is now called the Internet of Things, died on Wednesday at his home in Cambridge, Mass. He was 58. From a report: The cause was colon cancer, said his father, George Hawley. Mr. Hawley began his career as a video game programmer at Lucasfilm, the company created by the "Star Wars" director George Lucas. He spent his last 15 years curating the Entertainment Gathering, or EG, a conference dedicated to new ideas. In between, he worked at NeXT, the influential computer company founded by Steve Jobs after he left Apple in the mid-1980s, and spent nine years as a professor at the Massachusetts Institute of Technology Media Lab, a seminal effort to push science and technology into art and other disciplines. He was known as a scholar whose ideas, skills and friendships spanned an unusually wide range of fields, from mountain climbing to watchmaking. Mr. Hawley lived with both Mr. Jobs and the artificial intelligence pioneer Marvin Minsky, published the world's largest book, won first prize in an international competition of amateur pianists, played alongside the cellist Yo-Yo Ma at the wedding of the celebrity scientist Bill Nye, joined one of the first scientific expeditions to Mount Everest, and wrote commencement speeches for both Mr. Jobs and the Google co-founder Larry Page.

Two of Mr. Hawley's Media Lab projects -- Things That Think and Toys of Tomorrow -- anticipated the Internet of Things movement, which aims to weave digital technology into everything from cars to televisions to home lighting systems. Led by companies like Amazon, Google, Intel and Microsoft, the movement is now a $248 billion market, according to the market research firm Statista. Mr. Hawley developed "a pattern of ideas that emerged long before the Internet of Things," Nicholas Negroponte, founder of the Media Lab, said in an email. "I would call that pattern not artificial intelligence, but intelligence in the artificial," he wrote. Mark Seiden, an independent computer security consultant who met Mr. Hawley in the early 1980s when they were both working at IRCAM, a music lab in Paris, and eventually hired him at Lucasfilm, compared Mr. Hawley's exploits to those of George Plimpton, the writer whose participatory kind of journalism had him masquerading as a boxer, a professional football player, a circus performer and a stand-up comedian.

Taking place this week is the virtual Perl + Raku "Conference in the Cloud" as a result of the COVID-19 pandemic causing the event to go virtual. A big announcement out of it is Perl 7. From a report: Perl 7 basically amounts to Perl 5 with more modern defaults and foregoing some of the extensive backward compatibility support found with Perl 5. News of Perl 7 comes a few days after the release of Perl 5.32. Perl 7 succeeds Perl 5 due to the Perl 6 initiative previously for what is now known as the Raku programming language. So to avoid confusion, similar to the PHP 6 debacle, Perl 7 is the next version. For the most part though Perl 7 is close to Perl 5.32 with changed defaults and is more forward looking with less commitment to backward compatibility support.

Apple's Worldwide Developers Conference this week didn't bring any particularly revolutionary new feature, but it did something perhaps more important for Apple's long-term strategy. The latest updates will unify the company's devices and give customers more reasons to stay within its product ecosystem. From a report: From an average user's standpoint, the updates to iOS and iPadOS were underwhelming and minor, aside from widgets (which Android has had for years). Siri's interface changes were impressive, but there wasn't much discussion of a needed under-the-hood revamp, and the Watch update was incremental, other than sleep tracking. The company didn't let these products languish, but Apple's engineers essentially did just enough. The really impressive achievements came in getting the products to work together, plus sweeping improvements to the Mac.

The biggest news of the conference was that Apple-made chips will replace those from Intel in Mac computers. Besides higher speeds and longer battery life, the change customers will notice first is that Mac computers will work more like an iPhone or an iPad, and will have the ability to run the same apps on the new macOS Big Sur operating system. Soon, someone will be able to buy an iPhone app and run it across Apple's major platforms: the Mac, the iPhone, the iPad, and in some cases a variant of it on the Apple Watch and Apple TV. The company also moved toward increased unification by bringing over glance-able information (widgets) from the Apple Watch to its larger devices, and by more deeply integrating its smart home features across products. For example, a HomePod speaker can now be a doorbell and an Apple TV can be a door camera viewer. All of this may drive existing customers to buy additional Apple products, knowing that they'll work together seamlessly. The strategy could boost Apple's sales in the long-term and, just as importantly, make it more difficult for a user to leave behind a device, which could blow a hole in their network of Apple products.

The state of California has lost again in its attempt to punish IMDb for ageism perpetrated by movie studios who seem to refuse to cast actresses above a certain age in choice roles. Techdirt reports: The law passed by the California legislature does one thing: prevents IMDb (and other sites, theoretically) from publishing facts about actors: namely, their ages. This stupid law was ushered into existence by none other than the Screen Actors Guild, capitalizing on a (failed) lawsuit brought against the website by an actress who claimed the publication of her real age cost her millions in Hollywood paychecks. These beneficiaries of the First Amendment decided there was just too much First Amendment in California. To protect actors from studio execs, SAG decided to go after a third-party site respected for its collection of factual information about movies, actors, and everything else film-related.

The federal court handling IMDb's lawsuit against the state made quick work of the state's arguments in favor of very selective censorship. In only six pages, the court destroyed the rationale offered by the government's finest legal minds. [...] Even if the law had somehow survived a First Amendment challenge, it still wouldn't have prevented studios from engaging in discriminatory hiring practices. If this was really the state's concerns, it would have stepped up its regulation of the entertainment industry, rather than a single site that was unsuccessfully sued by an actress, who speculated IMDb's publication of her age was the reason she wasn't landing the roles she wanted.

At the WWDC 2020 keynote today, Apple announced that the company is going to switch from Intel chips to Apple's own silicon, based on ARM architecture. They also announced that iPad and iPhone apps will be able to run natively on ARM-powered Macs. TechCrunch reports: First, you'll be able to compile your app to run both on Intel-based Macs and ARM-based Macs. You can ship those apps with both executables using a new format called Universal 2. If you've been using a Mac for a while, you know that Apple used the same process when it switched from PowerPC CPUs to Intel CPUs -- one app, two executables. As for unoptimized software, you'll still be able to run those apps. But its performances won't be as good as what you'd get from a native ARM-ready app. Apple is going to ship Rosetta 2, an emulation layer that lets you run old apps on new Macs.

When you install an old app, your Mac will examine the app and try to optimize it for your ARM processor. This way, there will be some level of optimization even before you open the app. But what if it's a web browser or a complicated app with just-in-time code? Rosetta 2 can also translate instructions from x86 to ARM on the fly, while you're running the app. And if you're a developer working on code that is going to run on servers, Apple is also working on a set of virtualization tools. You'll be able to run Linux and Docker on an ARM Mac.

As a bonus, users will also be able to access a much larger library of apps. "Mac users can for the first time run iOS and iPadOS apps on the Mac," Apple CEO Tim Cook said. While the company didn't share a lot of details, Apple isn't talking about Catalyst, its own framework that makes it easier to port iOS apps to macOS. You should be able to download and run apps even if the developer never optimized those apps for macOS.

After rejecting an update last week, Apple has approved a new version of the subscription email app Hey. From a report: The approval, which came last week, ahead of today's Apple Worldwide Developer Conference, is meant to lower the temperature after Apple's initial app rejection drew widespread condemnation from lawmakers and other developers. But the approval is also only temporary in spirit, meant to give Hey developer Basecamp time to develop a version of the app more in line with Apple's policies -- and Basecamp's approach to that challenge is very aggressive, as a letter posted to its website today details.

The "bespoke development" site Evrone.com (an IT outsourcing company) interviewed Ruby on Rails creator David Heinemeier Hansson (who is also co-founder and CTO of Basecamp -- and a racecar driver) shortly before he spoke at RubyRussia, Evrone's annual Moscow programming conference.

And they asked him an interesting question. As a man who's seen lots of Ruby code, "what makes code good or shitty? Anything that is obvious for you at first glance?" David Heinemeier Hansson: If the code is poorly written, usually it smells before you even examine the logic. Indentation is off, styles are mixed, care is simply not shown. Beyond that, learning how to write great code, is a life long pursuit. As I said in my RailsConf 2014 keynote, we're not software engineers, we're software writers. "Writing" is a much more suitable metaphor for what we do most of the time than "engineering" is. Writing is about clarity and presenting information in a clear-to-follow manner so that anybody can understand it.

There's no list of principles and practices that somebody can be taught and then they will automatically produce clear writing every time. If you want to be a good writer, it's not enough just to memorize the dictionary. Just knowing the words available to you, knowing the patterns of development is not going to make you a good developer. You have to develop an eye. You have to decide that the most important thing for your system is clarity. When you do decide that, you can start developing an eye.

The only way to become a good programmer, where, by definition, I define good programmers as somebody who writes software with clarity, is to read a lot of software and write a lot of software.
In 2016, David Heinemeier Hansson answered questions from Slashdot readers.

An anonymous reader quotes technology columnist Mike Melanson: The debate around adding generics to the Go programming language has been going on for years now, often with much resistance, but it's starting to look like one proposal finally has some backing and general acceptance from the greater Go community — much to the surprise of some involved.

Introduced this week in a blog post looking at the next step for generics, penned by Golang team members Ian Lance Taylor and Robert Griesemer, the first update in nearly a year on the topic explains that the generics design draft previously submitted for feedback has been refined, resulting in an updated design draft... For the time being, the team has introduced an experimentation tool that "permits people to type check and run code written using the version of generics described in the design draft" by translating generic code into ordinary Go code. It is meant to give users a feel of how the proposed design would, if accepted work, and they note that it will be implemented differently if so.

As for the proposal itself, it offers several levels of detail, from an abstract, to a high-level overview, to the full level of detail you might expect from such a document. As with everything Go, the design is intended to be fully backward compatible with Go 1, and the authors note that "as the term generic is widely used in the Go community, we will use it below as a shorthand to mean a function or type that takes type parameters.

"Don't confuse the term generic as used in this design with the same term in other languages like C++, C#, Java, or Rust; they have similarities but are not the same."
The article also notes that Go's package repository is now open source.

Stack Overflow asked 65,000 programmers for their favorite programming language, and this year Microsoft's TypeScript knocked Python from the #2 spot. So they interviewed Microsoft's principal engineering lead for the language "to find out what about TypeScript makes it so dang lovable." Q: Do you remember why the team came up with TypeScript, why you wanted to release something like this?

A: When I joined the team, there were a lot of people at Microsoft who wanted to develop JavaScript at what we call "application scale." Teams like TFS and Office wanted to build large JavaScript applications. A lot of those people had familiarity with statically-typed languages — C++, C#, Java, that kind of thing. They wanted to have that static typing available both for conceptual scalability and for the tooling...

Q: Was there a point where you saw an adoption point of no return? Was there something that came along where people were like, oh, yeah, we do TypeScript now?

A: Oh, it was definitely Google announcing that they were going to use TypeScript with Angular. That's kind of lost to time now. But if you look at the graphs for TypeScript, literally any graph — GitHub stars, downloads, pull requests — you can see the exact point when that Angular announcement came out. And the graph just changes. It never looks back... TypeScript shores up that last rough edge on JavaScript and gives you something that's just really fun to work with and runs everywhere. I think if TypeScript were a language that was built on top of a less universal language or a less fun language, I don't think it would be as successful. It's really taking something that's great and making it better...

I think my favorite thing that I see is people on the Internet saying, 'I did this huge refactoring in TypeScript and I was refactoring for three hours. And then I ran my code and it worked the first time.' In a dynamic language, that would just never, ever happen....

I would just say to people, if static types aren't a good fit for you, for either your programming style or the problem you're working on, just skip it. That's fine. It's okay. I won't be offended. If someone can get a thirty thousand line application that gets its job done without static types, I'm very impressed. That just seems really difficult. But kudos to those people who make it work. Python's the same way. Very few people have working Python type annotations, but Python is incredibly popular. I think the data speaks for itself — I think Python is number three in the survey... I guarantee you that a very small proportion of those Python developers have static types. Whatever your problem domain is, that might be the best fit for you.

"GitHub says it's open-sourcing its in-house linting tool, the GitHub Super Linter, to clean up code," reports ZDNet: Having a tool that checks source code for programming blunders and other errors is useful for developers. Now Microsoft-owned GitHub has released the 'Super Linter' to help developers avoid the hassles of setting up code repositories with multiple linters...

GitHub describes it as a "simple combination of various linters, written in bash, to help validate your source code" for the purpose of preventing broken code from being uploaded to a 'master' branch, the key branch that other branches in a tree are merged to... The Super Linter Action lets developers 'lint' or check their code base using popular linters for Python, JavaScript, Go, XML, YAML, and more programming languages. As such, GitHub engineer Lucas Gravley describes the Super Linter as the "one linter to rule them all".

"The GitHub Super Linter was built out of necessity by the GitHub Services DevOps Engineering team to maintain consistency in our documentation and code while making communication and collaboration across the company a more productive experience," says Gravley... "When you've set your repository to start running this action, any time you open a pull request, it will start linting the code case and return via the Status API. It will let you know if any of your code changes passed successfully, or if any errors were detected, where they are, and what they are," explains Gravley.

The Super Linter doesn't fix problems but does flag them, so developers can then go back and fix them before they reach the master branch.

From a report: Have you ever wondered why online ads appear for things that you were just thinking about? There's no big conspiracy. Ad tech can be creepily accurate. Tech giant Oracle is one of a few companies in Silicon Valley that has near-perfected the art of tracking people across the internet. The company has spent a decade and billions of dollars buying startups to build its very own panopticon of users' web browsing data. One of those startups, BlueKai, which Oracle bought for a little over $400 million in 2014, is barely known outside marketing circles, but it amassed one of the largest banks of web tracking data outside of the federal government. BlueKai uses website cookies and other tracking tech to follow you around the web. By knowing which websites you visit and which emails you open, marketers can use this vast amount of tracking data to infer as much about you as possible -- your income, education, political views, and interests to name a few -- in order to target you with ads that should match your apparent tastes. If you click, the advertisers make money.

But for a time, that web tracking data was spilling out onto the open internet because a server was left unsecured and without a password, exposing billions of records for anyone to find. Security researcher Anurag Sen found the database and reported his finding to Oracle through an intermediary -- Roi Carthy, chief executive at cybersecurity firm Hudson Rock and former TechCrunch reporter.

STERIS Corporation, a company that makes sterilization and other medical equipment, sent a letter to iFixit claiming their online database of repair manuals for ventilators and medical equipment violates their copyrights. Motherboard reports: "It has come to my attention that you have been reproducing certain installation and maintenance manuals relating to our products, documentation which is protected by copyright law," the letter said. The letter then went on to tell [Kyle Wiens, CEO of iFixit] to remove all Steris copyrighted material from the iFixit website within 10 days of the letter. As Motherboard reported in March, major manufacturers of medical devices have long made it difficult for their devices to be repaired through third party repair professionals. Manufacturers have often lobbied against right to repair legislation and many medical devices are controlled by artificial "software locks" that allow only those with authorization to make modifications.

"I'm disappointed that Steris is resorting to legal threats to stop hospitals from having access to information about how to maintain critical sterilization equipment during a pandemic," Wiens told Motherboard in an email. "No manufacturer should be stopping hospitals from repairing their equipment," Wiens said. "The best way to ensure patient safety is to make sure that equipment is being maintained regularly using the manufacturer's recommended procedures. The only way to do that is if hospitals have up to date manuals." With regards to the letter sent by Steris, Wiens said iFixit has not removed any material from its website. "We explained to Steris that what we did is a lawful and protected fair use under the U.S. Copyright act," Wiens said. "iFixit is protected by Section 512 of the Digital Millennium Copyright Act, which allows online platforms to host content contributed by users provided they comply with the Act's requirements, which iFixit does," a letter to Steris from the Electronic Frontier Foundation on behalf of iFixit said.

The European Commission announced Tuesday that it's launching two antitrust investigations into Apple's App Store rules and the Apple Pay platform. From a report: The Commission, the executive arm of the EU, said it will assess whether Apple's rules for app developers on the distribution of apps via the App Store breach EU competition rules. While companies can place their apps on the App Store at no cost, Apple charges companies 30% from in-app purchases and 30% on subscriptions for the first year, then 15% thereafter. Spotify, which competes directly with Apple Music, feels this is unfair and filed a formal complaint in March 2019. Kobo, an e-reader company that competes with Apple Books, has also filed a complaint. Executive Vice-President Margrethe Vestager, in charge of competition policy, said in a statement: "Mobile applications have fundamentally changed the way we access content. Apple sets the rules for the distribution of apps to users of iPhones and iPads. It appears that Apple obtained a 'gatekeeper' role when it comes to the distribution of apps and content to users of Apple's popular devices. We need to ensure that Apple's rules do not distort competition in markets where Apple is competing with other app developers, for example with its music streaming service Apple Music or with Apple Books. I have therefore decided to take a close look at Apple's App Store rules and their compliance with EU competition rules."

Ahead of Apple's Worldwide Developer Conference starting next week, the company has today launched a new version of its Apple Developer App to better support its plans for the virtual event. TechCrunch reports: Notably, the app has been made available for Mac for the first time, in addition to a redesign and other minor feature updates. With the needs of an entirely virtual audience in mind, Apple has redesigned the app's Discover section to make it easier for developers to catch up on the latest stories, news, videos and more, the company says. This section will be regularly updated with "actionable" content, Apple notes, including the latest news, recommendations on implementing new features, and information about inspiring engineers and designers, alongside new videos.

It has also updated its Browse tab where users search for existing sessions, videos, articles and news, including the over 100 technical and design-focused videos found in the WWDC tab. The WWDC tab has also been updated in preparation for the live event starting on Monday, June 22. The redesign has added a way to favorite individual articles, in addition to session content and videos. Plus it includes new iMessage stickers along with other enhancements and bug fixes. The app, which was previously available on iPhone, iPad and Apple TV, is also now offered on Mac.

"The terms 'allowlist' and 'blocklist' describe their purpose, while the other words use metaphors to describe their purpose," reads a change description on the source code for Android -- from over a year ago. 9to5Mac calls it "a shortened version of Google's (internal-only) explanation" for terminology changes which are now becoming more widespread.

And Thursday GitHub's CEO said they were also "already working on" renaming the default branches of code from "master" to a more neutral term like "main," reports ZDNet: GitHub lending its backing to this movement effectively ensures the term will be removed across millions of projects, and effectively legitimizes the effort to clean up software terminology that started this month.

But, in reality, these efforts started years ago, in 2014, when the Drupal project first moved in to replace "master/slave" terminology with "primary/replica." Drupal's move was followed by the Python programming language, Chromium (the open source browser project at the base of Chrome), Microsoft's Roslyn .NET compiler, and the PostgreSQL and Redis database systems... The PHPUnit library and the Curl file download utility have stated their intention to replace blacklist/whitelist with neutral alternatives. Similarly, the OpenZFS file storage manager has also replaced its master/slave terms used for describing relations between storage environments with suitable replacements. Gabriel Csapo, a software engineer at LinkedIn, said on Twitter this week that he's also in the process of filing requests to update many of Microsoft's internal libraries.
A recent change description for the Go programming language says "There's been plenty of discussion on the usage of these terms in tech. I'm not trying to have yet another debate." It's clear that there are people who are hurt by them and who are made to feel unwelcome by their use due not to technical reasons but to their historical and social context. That's simply enough reason to replace them.

Anyway, allowlist and blocklist are more self-explanatory than whitelist and blacklist, so this change has negative cost.
That change was merged on June 9th -- but 9to5Mac reports it's just one of many places these changes are happening. "The Chrome team is beginning to eliminate even subtle forms of racism by moving away from terms like 'blacklist' and 'whitelist.' Google's Android team is now implementing a similar effort to replace the words 'blacklist' and 'whitelist.'" And ZDNet reports more open source projects are working on changing the name of their default Git repo from "master" to alternatives like main, default, primary, root, or another, including the OpenSSL encryption software library, automation software Ansible, Microsoft's PowerShell scripting language, the P5.js JavaScript library, and many others.
