While working at Apple, Chris Lattner designed Swift to "fully leverage the power of LLVM," and "led a team for a while at Google to try to move Swift out of its Apple comfort zone, to become a replacement for Python in AI model development." That's according to a blog post by Jeremy Howard, an advisor to Lattner's Modular AI (which he co-founded in 2022 to build a next-generation AI platform for developers).

"But sadly," Howard writes, Swift "did not receive the support it needed from either Apple or from Google, and it was not ultimately successful." And yet... [W]hilst at Google Chris did develop another project which became hugely successful: MLIR. MLIR is a replacement for LLVM's intermediate representation [or IR] for the modern age of many-core computing and AI workloads. It's critical for fully leveraging the power of hardware like GPUs, TPUs, and the vector units increasingly being added to server-class CPUs.

So, if Swift was "syntax sugar for LLVM", what's "syntax sugar for MLIR"? The answer is: Mojo! Mojo is a brand new language that's designed to take full advantage of MLIR. And also Mojo is Python.

Wait what?

OK let me explain. Maybe it's better to say Mojo is Python++. It will be (when complete) a strict superset of the Python language. But it also has additional functionality so we can write high performance code that takes advantage of modern accelerators...

Whereas Swift was a brand new language packing all kinds of cool features based on latest research in programming language design, Mojo is, at its heart, just Python. This seems wise, not just because Python is already well understood by millions of coders, but also because after decades of use its capabilities and limitations are now well understood. Relying on the latest programming language research is pretty cool, but its potentially-dangerous speculation because you never really know how things will turn out...

A key trick in Mojo is that you can opt in at any time to a faster "mode" as a developer, by using "fn" instead of "def" to create your function. In this mode, you have to declare exactly what the type of every variable is, and as a result Mojo can create optimised machine code to implement your function. Furthermore, if you use "struct" instead of "class", your attributes will be tightly packed into memory, such that they can even be used in data structures without chasing pointers around. These are the kinds of features that allow languages like C to be so fast, and now they're accessible to Python programmers too — just by learning a tiny bit of new syntax...

I can't begin to describe all the little (and big!) ideas throughout Mojo's design and implementation — it's the result of Chris and his team's decades of work on compiler and language design and includes all the tricks and hard-won experience from that time — but what I can describe is an amazing result that I saw with my own eyes.
Mojo hasn't been released to the public yet, (other than an online "playground" with a waitlist where they're "rolling out access slowly.") But the blog post notes that creating a programming language's syntax is usually complex, error-prone, and controversial — a problem Mojo neatly avoids by "outsourcing" its syntax to an existing language, "which also happens to be the most widely used language today."

And "As a compiled language, Mojo's deployment story is basically the same as C," the post argues. [That is, "you can literally just make the compiled program available for direct download. It can be just 100k or so in size, and will launch and run quickly."]

"This means that Mojo is far more than a language for AI/ML applications. It's actually a version of Python that allows us to write fast, small, easily-deployed applications that take advantage of all available cores and accelerators!"

OpenAI CEO Sam Altman told CNBC that the company no longer trains its AI large-language models such as GPT with paying customer data. "Customers clearly want us not to train on their data, so we've changed our plans: We will not do that," Altman told CNBC's Andrew Ross Sorkin. From the report: OpenAI's terms of service were quietly updated March 1, records from the Internet Archive's Wayback Machine show. "We don't train on any API data at all, we haven't for a while," Altman told CNBC. APIs, or application programming interfaces, are frameworks that allow customers to plug directly into OpenAI's software. OpenAI's business customers, which include Microsoft, Salesforce and Snapchat, are more likely to take advantage of OpenAI's API capabilities.

But OpenAI's new privacy and data protection extends only to customers who use the company's API services. "We may use Content from Services other than our API," the company's updated Terms of Use note. That could include, for example, text that employees enter into the wildly popular chatbot ChatGPT. Amazon reportedly recently warned employees not to share confidential information with ChatGPT for fear that it might show up in answers.

AI startup Hugging Face and ServiceNow Research, ServiceNow's R&D division, have released StarCoder, a free alternative to code-generating AI systems along the lines of GitHub's Copilot. From a report: Code-generating systems like DeepMind's AlphaCode; Amazon's CodeWhisperer; and OpenAI's Codex, which powers Copilot, provide a tantalizing glimpse at what's possible with AI within the realm of computer programming. Assuming the ethical, technical and legal issues are someday ironed out (and AI-powered coding tools don't cause more bugs and security exploits than they solve), they could cut development costs substantially while allowing coders to focus on more creative tasks.

According to a study from the University of Cambridge, at least half of developers' efforts are spent debugging and not actively programming, which costs the software industry an estimated $312 billion per year. But so far, only a handful of code-generating AI systems have been made freely available to the public -- reflecting the commercial incentives of the organizations building them (see: Replit). StarCoder, which by contrast is licensed to allow for royalty-free use by anyone, including corporations, was trained on over 80 programming languages as well as text from GitHub repositories, including documentation and programming notebooks. StarCoder integrates with Microsoft's Visual Studio Code code editor and, like OpenAI's ChatGPT, can follow basic instructions (e.g., "create an app UI") and answer questions about code.

Following the announcement of the bill in March, El Salvador President Nayib Bukele signed a law today eliminating income, property, capital gains, and other tariffs on technology innovations. Watcher Guru reports: The announcement reinforces El Salvador's perspective as a haven for technology development. Additionally, Bukele stated that the new act protects "technology innovations, software and app programming, AI, computer, and communications hardware manufacturing."

The Innovations and Technology Manufacturing Incentives Act will likely attract tech developments to the country. Moreover, the elimination of taxes presents an economic benefit to a host of companies. Conversely, El Salvador continues to maintain its commitment to a variety of tech innovations that are being developed.

T-Mobile on Monday said it experienced a hack that exposed account PINs and other customer data in the company's second network intrusion this year and the ninth since 2018. From a report: The intrusion, which started on February 24 and lasted until March 30, affected 836 customers, according to a notification on the website of Maine Attorney General Aaron Frey. "The information obtained for each customer varied but may have included full name, contact information, account number and associated phone numbers, T-Mobile account PIN, social security number, government ID, date of birth, balance due, internal codes that T-Mobile uses to service customer accounts (for example, rate plan and feature codes), and the number of lines," the company wrote in a letter sent to affected customers. Account PINs, which customers use to swap out SIM cards and authorize other important changes to their accounts, were reset once T-Mobile discovered the breach on March 27.

The incident is the second hack to hit T-Mobile this year. It's the ninth since 2018, based on reporting by TechCrunch. In January, T-Mobile said "bad actors" abused its application programming in a way that allowed them to access the data of 37 million customers. The hack started on November 25, 2022, and wasn't discovered by T-Mobile until January 5, TechCrunch said. Data obtained in that incident included names, billing addresses, email addresses, phone numbers, dates of birth, T-Mobile account numbers, and information such as the number of lines on accounts and plan features.

Researchers at the University of Minnesota report via Phys.Org: Biocomputing is typically done either with live cells or with non-living, enzyme-free molecules. Live cells can feed themselves and can heal, but it can be difficult to redirect cells from their ordinary functions toward computation. Non-living molecules solve some of the problems of live cells, but have weak output signals and are difficult to fine-tune and regulate. In new research published in Nature Communications, a team of researchers at the University of Minnesota has developed a platform for a third method of biocomputing: Trumpet, or Transcriptional RNA Universal Multi-Purpose GatE PlaTform.

Trumpet uses biological enzymes as catalysts for DNA-based molecular computing. Researchers performed logic gate operations, similar to operations done by all computers, in test tubes using DNA molecules. A positive gate connection resulted in a phosphorescent glow. The DNA creates a circuit, and a fluorescent RNA compound lights up when the circuit is completed, just like a lightbulb when a circuit board is tested.

The research team demonstrated that:

- The Trumpet platform has the simplicity of molecular biocomputing with added signal amplification and programmability.
- The platform is reliable for encoding all universal Boolean logic gates (NAND, NOT, NOR, AND, and OR), which are fundamental to programming languages.
- The logic gates can be stacked to build more complex circuits.

The team also developed a web-based tool facilitating the design of sequences for the Trumpet platform. "Trumpet is a non-living molecular platform, so we don't have most of the problems of live cell engineering," said co-author Kate Adamala, assistant professor in the College of Biological Sciences. "We don't have to overcome evolutionary limitations against forcing cells to do things they don't want to do. This also gives Trumpet more stability and reliability, with our logic gates avoiding the leakage problems of live cell operations."

"It could make a lot of long-term neural implants possible. The applications could range from strictly medical, like healing damaged nerve connections or controlling prosthetics, to more sci-fi applications like entertainment or learning and augmented memory," added Adamala.

Phoronix reports: With the financial backing of Amazon Web Services, sudo and su are being rewritten in the Rust programming language in order to increase the memory safety for the widely relied upon software... to further enhance Linux/open-source security.
"[B]ecause it's written in C, sudo has experienced many vulnerabilities related to memory safety issues," according to a blog post announcing the project: It's important that we secure our most critical software, particularly from memory safety vulnerabilities. It's hard to imagine software that's much more critical than sudo and su.

This work is being done by a joint team from Ferrous Systems and Tweede Golf with generous support from Amazon Web Services. The work plan is viewable here. The GitHub repository is here.

HackerNoon tested five AI bots on coding problems from Leetcode.com — GPT-4, GitHub Co-Pilot, Bard, Bing, and Claude+.

There's some interesting commentary on the strengths and weaknesses of each one -- and of course, the code that they ultimately output. The final results? [GPT-4's submission] passes all tests. It beat 47% of submissions on runtime and 8% on memory. GPT-4 is highly versatile in generating code for various programming languages and applications. Some of the caveats are that it takes much longer to get a response. API usage is also a lot more expensive and costs could ramp up quickly. Overall it got the answer right and passed the test.

[Bing's submission] passed all the tests. It beat 47% of submissions on runtime and 37% on memory. This code looks a lot simpler than what GPT-4 generated. It beat GPT-4 on memory and it used less code! Bing seems to have the most efficient code so far, however, it gave a very short explanation of how it solved it. Nonetheless, best so far.
But both Bard and Claude+ failed the submission test (badly), while GitHub Copilot "passes all the tests. It scored better than 30% of submissions on runtime and 37% on memory."

Microsoft is rewriting core Windows libraries in the Rust programming language, and the more memory-safe code is already reaching developers. From a report: David "dwizzle" Weston, director of OS security for Windows, announced the arrival of Rust in the operating system's kernel at BlueHat IL 2023 in Tel Aviv, Israel, last month. "You will actually have Windows booting with Rust in the kernel in probably the next several weeks or months, which is really cool," he said. "The basic goal here was to convert some of these internal C++ data types into their Rust equivalents."

Microsoft showed interest in Rust several years ago as a way to catch and squash memory safety bugs before the code lands in the hands of users; these kinds of bugs were at the heart of about 70 percent of the CVE-listed security vulnerabilities patched by the Windows maker in its own products since 2006. The Rust toolchain strives to prevent code from being built and shipped that is exploitable, which in an ideal world reduces opportunities for miscreants to attack weaknesses in software. Simply put, Rust is focused on memory safety and similar protections, which cuts down on the number of bad bugs in the resulting code. Rivals like Google have already publicly declared their affinity for Rust.

Last year Python's massive PyPI repository of pre-written software packages had 235.7 billion downloads — a 57% annual growth in its download counts and bandwidth. So now Python's nonprofit Python Software Foundation has an announcement.

Their director of infrastructure said today that they're rolling out "the first step in our plan to build financial support and long-term sustainability of PyPI, while simultaneously giving our users one of our most requested features: organization accounts." Organizations on PyPI are self-managed teams, with their own exclusive branded web addresses. Our goal is to make PyPI easier to use for large community projects, organizations, or companies who manage multiple sub-teams and multiple packages.

We're making organizations available to community projects for free, forever, and to corporate projects for a small fee. Additional priority support agreements will be available to all paid subscribers, and all revenue will go right back into PyPI to continue building better support and infrastructure for all our users... Having more people using and contributing to Python every year is an fantastic problem to have, but it is one we must increase organizational capacity to accommodate. Increased revenue for PyPI allows it to become a staffed platform that can respond to support requests and attend to issues in a timeframe that is significantly faster than what our excellent (but thinly spread) largely volunteer team could reasonably handle.

We want to be very clear — these new features are completely optional. If features for larger projects don't sound like something that would be useful to you as a PyPI maintainer, then there is no obligation to create an organization and absolutely nothing about your PyPI experience will change for you.

We look forward to discussing what other features PyPI users would like to see tackled next...

Long-time Slashdot reader theodp writes: According to Google Trends, peak "Lean to Code" occurred in early 2019 when laid-off Buzzfeed and Huffpost journalists were taunted with the phrase on Twitter... As Meta founder and CEO Mark Zuckerberg recently put it, "We're in a different world." Indeed. Encouraging kids to pursue CS careers in Code.org's viral 2013 launch video, Zuckerberg explained, "Our policy at Facebook is literally to hire as many talented engineers as we can find."

In Learning to Code Isn't Enough, a new MIT Technology Review article, Joy Lisi Rankin reports on the long history of learn-to-code efforts, which date back to the 1960s. "Then as now," Lisi Rankin writes, "just learning to code is neither a pathway to a stable financial future for people from economically precarious backgrounds nor a panacea for the inadequacies of the educational system."
But is that really true? Vox does note that the latest round of layoffs at Meta "is impacting workers in core technical roles like data scientists and software engineers — positions once thought to be beyond reproach." Yet while that's also true at other companies, those laid-off tech workers also seem to be finding similar positions by working in other industries: Software engineers were the most overrepresented position in layoffs in 2023, relative to their employment, according to data requested by Vox from workforce data company Revelio Labs. Last year, when major tech layoffs first began, recruiters and customer success specialists experienced the most outsize impact. So far this year, nearly 20 percent of the 170,000 tech company layoffs were software engineers, even though they made up roughly 14 percent of employees at these companies. "Early layoffs were dominated by recruiters, which is forgoing future hiring," Revelio senior economist Reyhan Ayas told Vox. "Whereas in 2023 we see a shift toward more core engineering and software engineering, which signals a change in focus of current business priorities."

In other words, tech companies aren't just trimming the fat by firing people who fill out their extensive ecosystem, which ranges from marketers to massage therapists. They're also, many for the first time, making cuts to the people who build the very products they're known for, and who enjoyed a sort of revered status since they, like the founders of the companies, were coders. Software engineers are still important, but they don't have the power they used to...

The latest monthly jobs report by tech industry association CompTIA found that even though employment at tech companies (which includes all roles at those companies) declined slightly in March, employment in technical occupations across industry sectors increased by nearly 200,000 positions. So even if tech companies are laying off tech workers, other industries are snatching them up. Unfortunately for software engineers and the like, that means they might also have to follow those industries' pay schemes. The average software engineer base pay in the US is $90,000, according to PayScale, but can be substantially higher at tech firms like Facebook, where such workers also get bonuses and stock options.

The Rust team released a new version Thursday — Rust 1.69.0 — boasting over over 3,000 new commits from over 500 contributors.

Phoronix highlights two new improvements: In order to speed-up compilation speeds, Rust 1.69 and moving forward debug information is no longer included in build scripts by default. Cargo will avoid emitting debug information in build scripts by default — leading to less informative backtraces in build scripts when problems arise, but faster build speeds by default. Those wanting the debug information emitted can now set the debug flag in their Cargo.toml configuration.

The Cargo build shipped by Rust 1.69 is also now capable of suggesting fixes automatically for some of the generated warnings. Cargo will also suggest using "cargo fix" / "cargo clippy --fix" when it knows the errors can be automatically fixed.

"The Rust Foundation on Monday apologized for confusion caused by the organization's proposed trademark policy changes," reports the Register.

The Foundation now says their proposed policy "clearly needs improvement" and "there are many valid critiques of the initial draft," promising to address them and adopt a more transparent process (with a report summarizing the feedback soon). From the Register's report: The foundation, which provides financial and legal support for the memory-safe programming language, had proposed fresh rules on the use of the word Rust and its logo, which included the recommendation that people not use 'Rust' in their Rust crate names, eg: vulture-rs would be preferred over vulture-rust. These draft changes triggered a backlash... Over the weekend, Rust creator Graydon Hoare voiced support for the community's objections in a Reddit discussion thread, in response to a post by programmer Andrew Gallant, a former member of the Rust moderation team, who argued the new policy was not all that different from the old one.

"Open them up side by side — old and new — and look at what they each say about, specifically, package names, project names, repos or websites using the word 'rust', or modified versions of the logo used for small groups or projects," wrote Hoare. "These are specifically the things people are upset about, because they all changed from 'acceptable' to 'prohibited' when 'clarifying' the policy. And those are specifically things that everyone in the community does, and has done, for years. There are zillions of packages, projects, repos, websites and groups using the names and logo this way, as the old policy said they could. The new policy tells them all to stop."
Long-time open source advocate Bruce Perens told the Register that Rust's trademark policy "goes far awry of fair use which is legally permitted. Books on Rust will always have its name in their title, commercial products will be advertised as being written in Rust, being compatible with Rust, or compiling Rust. But the policy attempts to deny permission for these things. A proper trademark policy prevents others from representing that their product is Rust or is endorsed by the trademark holder of Rust. That's really as much as you can ever enforce, so there's no sense in a policy that asks for more."

The Register also spoke to Ashley Williams, a former member of the Rust core team and the original executive director and founder of the Rust Foundation, who argued upheaval in Rust's governance over the past year led to a team with less experience dealing with the Rust community. "I think a couple of very passionate people participated in the trademark working group and they didn't involve a lot of people who have even basic experience interacting with the community. So really classic community behaviors ended up getting prohibited in that [draft] policy. And that's really why everybody got upset. The policy ultimately said, 'a thing that you do all the time as a way of contributing to the Rust community is now against our policy.'"

ChatGPT, OpenAI's large language model for chatbots, not only produces mostly insecure code but also fails to alert users to its inadequacies despite being capable of pointing out its shortcomings. The Register reports: Amid the frenzy of academic interest in the possibilities and limitations of large language models, four researchers affiliated with Universite du Quebec, in Canada, have delved into the security of code generated by ChatGPT, the non-intelligent, text-regurgitating bot from OpenAI. In a pre-press paper titled, "How Secure is Code Generated by ChatGPT?" computer scientists Raphael Khoury, Anderson Avila, Jacob Brunelle, and Baba Mamadou Camara answer the question with research that can be summarized as "not very."

"The results were worrisome," the authors state in their paper. "We found that, in several cases, the code generated by ChatGPT fell well below minimal security standards applicable in most contexts. In fact, when prodded to whether or not the produced code was secure, ChatGPT was able to recognize that it was not." [...] In all, ChatGPT managed to generate just five secure programs out of 21 on its first attempt. After further prompting to correct its missteps, the large language model managed to produce seven more secure apps -- though that's "secure" only as it pertains to the specific vulnerability being evaluated. It's not an assertion that the final code is free of any other exploitable condition. [...]

The academics observe in their paper that part of the problem appears to arise from ChatGPT not assuming an adversarial model of code execution. The model, they say, "repeatedly informed us that security problems can be circumvented simply by 'not feeding an invalid input' to the vulnerable program it has created." Yet, they say, "ChatGPT seems aware of -- and indeed readily admits -- the presence of critical vulnerabilities in the code it suggests." It just doesn't say anything unless asked to evaluate the security of its own code suggestions.

Initially, ChatGPT's response to security concerns was to recommend only using valid inputs -- something of a non-starter in the real world. It was only afterward, when prompted to remediate problems, that the AI model provided useful guidance. That's not ideal, the authors suggest, because knowing which questions to ask presupposes familiarity with specific vulnerabilities and coding techniques. The authors also point out that there's ethical inconsistency in the fact that ChatGPT will refuse to create attack code but will create vulnerable code.

An anonymous reader quotes a report from Wired: Stack Overflow, a popular internet forum for computer programming help, plans to begin charging large AI developers as soon as the middle of this year for access to the 50 million questions and answers on its service, CEO Prashanth Chandrasekar says. The site has more than 20 million registered users. Stack Overflow's decision to seek compensation from companies tapping its data, part of a broader generative AI strategy, has not been previously reported. It follows an announcement by Reddit this week that it will begin charging some AI developers to access its own content starting in June.

"Community platforms that fuel LLMs absolutely should be compensated for their contributions so that companies like us can reinvest back into our communities to continue to make them thrive," Stack Overflow's Chandrasekar says. "We're very supportive of Reddit's approach." Chandrasekar described the potential additional revenue as vital to ensuring Stack Overflow can keep attracting users and maintaining high-quality information. He argues that will also help future chatbots, which need "to be trained on something that's progressing knowledge forward. They need new knowledge to be created." But fencing off valuable data also could deter some AI training and slow improvement of LLMs, which are a threat to any service that people turn to for information and conversation. Chandrasekar says proper licensing will only help accelerate development of high-quality LLMs.

Chandrasekar says that LLM developers are violating Stack Overflow's terms of service. Users own the content they post on Stack Overflow, as outlined in its TOS, but it all falls under a Creative Commons license that requires anyone later using the data to mention where it came from. When AI companies sell their models to customers, they "are unable to attribute each and every one of the community members whose questions and answers were used to train the model, thereby breaching the Creative Commons license," Chandrasekar says. Neither Stack Overflow nor Reddit has released pricing information. "Both Stack Overflow and Reddit will continue to license data for free to some people and companies," notes Wired. "Chandrasekar says Stack Overflow only wants remuneration only from companies developing LLMs for big, commercial purposes."

"When people start charging for products that are built on community-built sites like ours, that's where it's not fair use," he says.

The Linux Foundation, the nonprofit tech consortium that manages various open source efforts, today announced the launch of the TLA+ Foundation to promote the adoption and development of the TLA+ programming language. AWS, Oracle and Microsoft are among the inaugural members. From a report: What is the TLA+ programming language, you ask? It's a formal "spec" language developed by computer scientist and mathematician Leslie Lamport. Best known for his seminal work in distributed systems, Lamport -- now a scientist at Microsoft Research -- created TLA+ to design, model, document and verify software programs -- particularly those of the concurrent and distributed variety.

To give a few examples, ElasticSearch, the organization behind the search engine of the same name, used TLA+ to verify the correctness of their distributed systems algorithms. Elsewhere, Thales, the electrical systems manufacturing firm, used TLA+ to model and develop fault-tolerant modules for its industrial control platform. "TLA+ is unique in that it's intended for specifying a system, rather than for implementing software," a Linux Foundation spokesperson told TechCrunch via email. "Based on mathematical concepts, notably set theory and temporal logic, TLA+ allows for the expression of a system's desired correctness properties in a formal and rigorous manner."

Google is updating its Bard AI chatbot to help developers write and debug code. Rivals like ChatGPT and Bing AI have supported code generation, but Google says it has been "one of the top requests" it has received since opening up access to Bard last month. From a report: Bard can now generate code, debug existing code, help explain lines of code, and even write functions for Google Sheets. "We're launching these capabilities in more than 20 programming languages including C++, Go, Java, Javascript, Python and Typescript," explains Paige Bailey, group product manager for Google Research, in a blog post. You can ask Bard to explain code snippets or explain code within GitHub repos similar to how Microsoft-owned GitHub is implementing a ChatGPT-like assistant with Copilot. Bard will also debug code that you supply or even its own code if it made some errors or the output wasn't what you were looking for.

Reddit has long been a forum for discussion on a huge variety of topics, and companies like Google and OpenAI have been using it in their A.I. projects. From a report: Reddit has long been a hot spot for conversation on the internet. About 57 million people visit the site every day to chat about topics as varied as makeup, video games and pointers for power washing driveways. In recent years, Reddit's array of chats also have been a free teaching aid for companies like Google, OpenAI and Microsoft. Those companies are using Reddit's conversations in the development of giant artificial intelligence systems that many in Silicon Valley think are on their way to becoming the tech industry's next big thing. Now Reddit wants to be paid for it.

The company said on Tuesday that it planned to begin charging companies for access to its application programming interface, or A.P.I., the method through which outside entities can download and process the social network's vast selection of person-to-person conversations. "The Reddit corpus of data is really valuable," Steve Huffman, founder and chief executive of Reddit, said in an interview. "But we don't need to give all of that value to some of the largest companies in the world for free." The move marks one of the first significant examples of a social network's charging for access to the conversations it hosts for the purpose of developing A.I. systems like ChatGPT, OpenAI's popular program. Those new A.I. systems could one day lead to big businesses, but they aren't likely to help companies like Reddit very much. In fact, they could be used to create competitors -- automated duplicates to Reddit's conversations.

"Java would become easier for students to learn under a proposal to introduce flexible main methods and anonymous main classes to the language," reports InfoWorld.

Details of the plan include enhancing the protocol by which Java programs are launched to be flexible, in particular to allow the String[] parameter of main methods to be omitted and allow main methods to be neither public nor static; the Hello World program would be simplified. Anonymous main classes would be introduced to make the class declaration implicit.
It's currently a disabled-by-default preview language feature in JDK 21 (scheduled for General Availability in September), included to provoke developer feedback based on real world use (which may lead to it becoming permanent in the future). This wouldn't introduce a separate beginner's dialect or beginners' toolchain of Java, emphasizes Java Enhancement Proposal (JEP) 445. "Student programs should be compiled and run with the same tools that compile and run any Java program."

But it argues that a simple "Hello World" program today has "too much clutter...too much code, too many concepts, too many constructs — for what the program does."


public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}



Anonymous main classes would make the public class declaration implicit (while also sparing newbies the "mysterious" modifier static and the args parameter String[] ). The program is streamlined to:


void main() {
System.out.println("Hello, World!");
}


The proposal argues this change reduces "the ceremony of writing simple programs such as scripts and command-line utilities." And since Java is intended to be a first programming language, this change would mean students "can write their first programs without needing to understand language features designed for large programs," using instead "streamlined declarations for single-class programs". (This allows students and educators to explore language features more gradually.) A Hello, World! program written as an anonymous main class is much more focused on what the program actually does, omitting concepts and constructs it does not need. Even so, all members are interpreted just as they are in an ordinary class. To evolve an anonymous main class into an ordinary class, all we need to do is wrap its declaration, excluding import statements, inside an explicit class declaration.
