Databricks CTO Matei Zaharia "said that Databricks had to keep track of scheduling a million things," remembers adjunct MIT professor Michael Stonebraker. " He said that this can't be done with traditional operating system scheduling, and so this was done out of a Postgres database. And then he started to whine that Postgres was too slow, and I told him we can do better than that...."

This resulted in DBOS — short for "database operating system" — which they teamed up to build with teams Stanford and MIT, according to The Next Platform: They founded a company to commercialize the idea in April 2023 and secured $8.5 million initial seed funding to start building the real DBOS. Engine Ventures and Construct Capital led the funding, along with Sinewave and GutBrain Ventures...

"The state that the operating system has to keep track of — memory, files, messages, and so on — is approximately linear to the resources you have got," says Stonebraker. "So without me saying another word, keeping track of operating system state is a database problem not addressed by current operating system schedulers. Moreover, OLTP [Online Transaction Processing] database performance has gone up dramatically, and that is why we thought instead of running the database system in user space on top of the operating system, why don't we invert our thinking 180 degrees and run the operating system on top of the database, with all of the operating services are coded in SQL...?"

For now, DBOS can give the same kind of performance as that full blown Linux operating system, and thanks to the distributed database underpinnings of its kernel, it can do things that a Linux kernel just cannot do... One is provide reliable execution, which means that if a program running atop DBOS is ever interrupted, it starts where it left off and does not have to redo its work from some arbitrary earlier point and does not crash and have to start from the beginning. And because every little bit of the state of the operating system — and therefore the applications that run atop it — is preserved, you can go backwards in time in the system and restart the operating system if it experiences some sort of anomaly, such as a bad piece of application software running or a hack attack. You can use this "time travel" feature, as Stonebraker calls it, to reproduce what are called heisenbugs — ones that are very hard to reproduce precisely because there is no shared state in the distributed Linux and Kubernetes environment and that are increasingly prevalent in a world of microservices.

The other benefit of the DBOS is that it presents a smaller attack surface for hackers, which boosts security, and that you analyze the metrics of the operating system in place since they are already in a NoSQL database that can be queried rather than aggregating a bunch of log files from up and down the software stack to try to figure out what is going on...

There is also a custom tier for DBOS, which we presume costs money, that can use other databases and datastores for user application data, stores more than three days of log data, can have multiple users per account, that adds email and Slack support with DBOS techies, and that is available on other clouds as well as AWS.
The operating system kernel/scheduler "is itself largely a database," with services written in TypeScript, according to the article. The first iteration used the FoundationDB distributed key-value store for its scheduling core (open sourced by Apple in 2018), according to the article — "a blazingly fast NoSQL database... Stonebraker says there is no reason to believe that DBOS can't scale across 1 million cores or more and support Java, Python, and other application languages as they are needed by customers..."

And the article speculates they could take things even further. "There is no reason why DBOS cannot complete the circle and not only have a database as an operating system kernel, but also have a relational database as the file system for applications."

Researchers at Cado Security Labs received an alert about a honeypot using the Docker Engine API. "A Docker command was received..." they write, "that spawned a new container, based on Alpine Linux, and created a bind mount for the underlying honeypot server's root directory..." Typically, this is exploited to write out a job for the Cron scheduler to execute... In this particular campaign, the attacker exploits this exact method to write out an executable at the path /usr/bin/vurl, along with registering a Cron job to decode some base64-encoded shell commands and execute them on the fly by piping through bash.

The vurl executable consists solely of a simple shell script function, used to establish a TCP connection with the attacker's Command and Control (C2) infrastructure via the /dev/tcp device file. The Cron jobs mentioned above then utilise the vurl executable to retrieve the first stage payload from the C2 server... To provide redundancy in the event that the vurl payload retrieval method fails, the attackers write out an additional Cron job that attempts to use Python and the urllib2 library to retrieve another payload named t.sh
"Multiple user mode rootkits are deployed to hide malicious processes," they note. And one of the shell scripts "makes use of the shopt (shell options) built-in to prevent additional shell commands from the attacker's session from being appended to the history file... Not only are additional commands prevented from being written to the history file, but the shopt command itself doesn't appear in the shell history once a new session has been spawned."

The same script also inserts "an attacker-controlled SSH key to maintain access to the compromised host," according to the article, retrieves a miner for the Monero cryptocurrency and then "registers persistence in the form of systemd services" for both the miner and an open source Golang reverse shell utility named Platypus.

It also delivers "various utilities," according to the blog Security Week, "including 'masscan' for host discovery." Citing CADO's researchers, they write that the shell script also "weakens the machine by disabling SELinux and other functions and by uninstalling monitoring agents." The Golang payloads deployed in these attacks allow attackers to search for Docker images from the Ubuntu or Alpine repositories and delete them, and identify and exploit misconfigured or vulnerable Hadoop, Confluence, Docker, and Redis instances exposed to the internet... ["For the Docker compromise, the attackers spawn a container and escape from it onto the underlying host," the researchers writes.]

"This extensive attack demonstrates the variety in initial access techniques available to cloud and Linux malware developers," Cado notes. "It's clear that attackers are investing significant time into understanding the types of web-facing services deployed in cloud environments, keeping abreast of reported vulnerabilities in those services and using this knowledge to gain a foothold in target environments."

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) will start providing more hands-on support to open-source software developers as they work to better secure their projects, the agency said. From a report: CISA hosted a two-day, invite-only summit this week with leaders in the open-source software community and other federal officials. During the private event, the agency also ran what's likely the first tabletop exercise to assess how well the government and the open-source community would respond to a cyberattack targeting one of their projects.

During the summit, CISA and a handful of package repositories unveiled new initiatives to help secure open-source projects. CISA is working on a new communication channel where open-source software developers can share threat intelligence and ask the agency for assistance during an incident. The Rust Foundation is developing new public key infrastructure for its repository, which will help ensure that the code developers are uploading isn't malicious and is coming from legitimate users.

npm, which manages the JavaScript programming language, is requiring project maintainers to enroll in multi-factor authentication and is rolling out a tool to generate "software bills of materials," which provide a recipe list of what code and other elements are in a project. Additional repositories -- including the Python Software Foundation, Packagist, Composer and Maven Central -- are pursuing similar projects and also also rolling out tools to help detect and report malware and other security vulnerabilities.

Rust's official survey team released results from their 8th annual survey "focused on gathering insights and feedback from Rust users". In terms of operating systems used by Rustaceans, the situation is very similar to the results from 2022, with Linux being the most popular choice of Rust users [69.7%], followed by macOS [33.5%] and Windows [31.9%], which have a very similar share of usage. Rust programmers target a diverse set of platforms with their Rust programs, even though the most popular target by far is still a Linux machine [85.4%]. We can see a slight uptick in users targeting WebAssembly [27.1%], embedded and mobile platforms, which speaks to the versatility of Rust.

We cannot of course forget the favourite topic of many programmers: which IDE (developer environment) do they use. Visual Studio Code still seems to be the most popular option [61.7%], with RustRover (which was released last year) also gaining some traction [16.4%].
The site ITPro spoke to James Governor, co-founder of the developer-focused analyst firm RedMonk, who said Rust's usage is "steadily increasing", pointing to its adoption among hyperscalers and cloud companies and in new infrastructure projects. "Rust is not crossing over yet as a general-purpose programming language, as Python did when it overtook Java, but it's seeing steady growth in adoption, which we expect to continue. It seems like a sustainable success story at this point."

But InfoWorld writes that "while the use of Rust language by professional programmers continues to grow, Rust users expressed concerns about the language becoming too complex and the low level of Rust usage in the tech industry." Among the 9,374 respondents who shared their main worries for the future of Rust, 43% were most concerned about Rust becoming too complex, a five percentage point increase from 2022; 42% were most concerned about low usage of Rust in the tech industry; and 32% were most concerned about Rust developers and maintainers not being properly supported, a six percentage point increase from 2022. Further, the percentage of respondents who were not at all concerned about the future of Rust fell, from 30% in 2022 to 18% in 2023.

From a blog post by Greg Kroah-Hartman: As was recently announced, the Linux kernel project has been accepted as a CVE Numbering Authority (CNA) for vulnerabilities found in Linux.

This is a trend, of more open source projects taking over the haphazard assignments of CVEs against their project by becoming a CNA so that no other group can assign CVEs without their involvment. Here's the curl project doing much the same thing for the same reasons. I'd like to point out the great work that the Python project has done in supporting this effort, and the OpenSSF project also encouraging it and providing documentation and help for open source projects to accomplish this. I'd also like to thank the cve.org group and board as they all made the application process very smooth for us and provided loads of help in making this all possible.

As many of you all know, I have talked a lot about CVEs in the past, and yes, I think the system overall is broken in many ways, but this change is a way for us to take more responsibility for this, and hopefully make the process better over time. It's also work that it looks like all open source projects might be mandated to do with the recent rules and laws being enacted in different parts of the world, so having this in place with the kernel will allow us to notify all sorts of different CNA-like organizations if needed in the future.
Kroah-Hartman links to his post on the kernel mailing list for "more details about how this is all going to work for the kernel." [D]ue to the layer at which the Linux kernel is in a system, almost any bug might be exploitable to compromise the security of the kernel, but the possibility of exploitation is often not evident when the bug is fixed. Because of this, the CVE assignment team are overly cautious and assign CVE numbers to any bugfix that they identify. This explains the seemingly large number of CVEs that are issued by the Linux kernel team...

No CVEs will be assigned for unfixed security issues in the Linux kernel, assignment will only happen after a fix is available as it can be properly tracked that way by the git commit id of the original fix. No CVEs will be assigned for any issue found in a version of the kernel that is not currently being actively supported by the Stable/LTS kernel team.
alanw (Slashdot reader #1,822) worries this could overwhelm the CVE infrastructure, pointing to an ongoing discussion at LWN.net.

But reached for a comment, Greg Kroah-Hartman thinks there's been a misunderstanding. He told Slashdot that the CVE group "explicitly asked for this as part of our application... so if they are comfortable with it, why is no one else?"

The Tiobe index tries to gauge the popularity of programming languages based on search results for courses, programmers, and third-party vendors, according to InfoWorld.

And by that criteria, "Google's Go language, or golang, has reached its highest position ever..." The language, now in the eighth ranked position for language popularity, has been on the rise for several years.... In 2015, Go hit position #122 in the TIOBE index and all seemed lost," said Paul Jansen, CEO of Tiobe. "One year later, Go adopted a very strict 'half-a-year' release cycle — backed up by Google. Every new release, Go improved... Nowadays, Go is used in many software fields such as back-end programming, web services and APIs," added Jansen...

Elsewhere in the February release of Tiobe's index, Google's Carbon language, positioned as a successor to C++, reached the top 100 for the first time. Python is #1 on both TIOBE's index and the alternative Pypl Popularity of Programming Language index, which InfoWorld says "assesses language popularity based on how often language tutorials are searched on in Google." But the two lists differ on whether Java and JavaScript are more popular than C-derived languages — and which languages should then come after them. (Go ranks #12 on the Pypl index...)

Meta's latest update to its code generation AI model, Code Llama 70B, is "the largest and best-performing model" yet. From a report: Code Llama tools launched in August and are free for both research and commercial use. According to a post on Meta's AI blog, Code Llama 70B can handle more queries than previous versions, which means developers can feed it more prompts while programming, and it can be more accurate. Code Llama 70B scored 53 percent in accuracy on the HumanEval benchmark, performing better than GPT-3.5's 48.1 percent and closer to the 67 percent mark an OpenAI paper (PDF) reported for GPT-4. Built on Llama 2, Code Llama helps developers create strings of code from prompts and debug human-written work. Meta simultaneously launched two other Code Llama tools last fall, Code Llama -- Python and Code Llama -- Instruct, which focused on specific coding languages.

The tech site IT Brew looks at an open-source tool that "uses AI to offer efficiency-minded suggestions to Python coders." Known as "Scalene," the profiler — a kind of debugger for performance issues — has been downloaded more than 900,000 times on GitHub. "It's awesome in general, and amazing for an academic project," UMass professor Emery Berger, who worked with PhD students Sam Stern and Juan Altmayer Pizzorno on the open-source tool, told IT Brew...

Scalene measures how much time and memory is spent on each line of code — both on average and at peak, [and] how much time is spent in efficient libraries and how much is spent in Python... By selecting a lightning-bolt icon, a user can "leverage the engine that powers ChatGPT to get an optimization" suggestion, Berger said. In one demo he showed IT Brew, an output recommended a less-memory-intensive move to reduce a very large array created by the code...

"If your Python code already runs fast enough, then you don't need a profiler. But if it's running slow, I think it's a very convenient profiler to reach for," Berger said.

Kevin Purdy reports via Ars Technica: Sometimes, a great song can come from great pain. The Game Boy Advance (GBA), its software having crashed nearly two hours ago, will, for example, play a tune based on the game inside it. And if you listen closely enough -- using specialty hardware and code -- you can tell exactly what game it was singing about. And then theoretically play that same game. This was discovered recently by TheZZAZZGlitch, whose job is to "sadistically glitch and hack the crap out of Pokemon games. It's "hardly a ready-to-use solution," the modder notes, as it requires a lot of tuning specific to different source formats. So while there are certainly easier ways to get GBA data from a cartridge, none make you feel quite so much like an audio datamancer.

After crashing a GBA and recording it over four hours, the modder saw some telltale waveforms in a sound file at about the 1-hour, 50-minute mark. Later in the sound-out, you can hear the actual instrument sounds and audio samples the game contains, played in sequence. Otherwise, it's 8-bit data at 13,100 Hz, and at times, it sounds absolutely deranged. "2 days of bugfixing later," the modder had a Python script ready that could read the audio from a clean recording of the GBA's crash dump. Did it work? Not without more troubleshooting. One issue with audio-casting ROM data is that there are large sections of 0-byte data in the ROM, which are hard to parse as mute sounds. After running another script that realigned sections based on their location in the original ROM, the modder's ROM was 99.76 percent accurate but "still didn't boot tho." TheZZAZZGlitch later disclaimed that, yes, this is technically using known ROM data to surface unknown data, or "cheating," but there are assumptions and guesses one could make if you were truly doing this blind.

The next fix was to refine the sound recording. By recording three times and merging them with a "majority vote" algorithm, their accuracy notched up to 99.979 percent. That output ROM booted -- but with glitched text and a title screen crash. After seven different recordings are meshed and filtered for blank spaces, they achieve 100 percent parity. You can watch the video describing this feat here. Used source code is also available under the file name "gbacrashsound_dumper.zip."

Last April the Python Software Foundation warned that Europe's proposed Cyber Resilience Act jeopardized their organization and "the health of the open-source software community" with overly broad policies that "will unintentionally harm the users they are intended to protect."

They'd worried that the Python Software Foundation could incur financial liabilities just for hosting Python and its PyPI package repository due to the proposed law's attempts to penalize cybersecurity lapses all the way upstream. But a new blog post this week cites some improvements: We asked for increased clarity, specifically:

"Language that specifically exempts public software repositories that are offered as a public good for the purpose of facilitating collaboration would make things much clearer. We'd also like to see our community, especially the hobbyists, individuals and other under-resourced entities who host packages on free public repositories like PyPI be exempt."


The good news is that CRA text changed a lot between the time the open source community — including the PSF — started expressing our concerns and the Act's final text which was cemented on December 1st. That text introduces the idea of an "open source steward."

"'open-source software steward' means any legal person, other than a manufacturer, which has the purpose or objective to systematically provide support on a sustained basis for the development of specific products with digital elements qualifying as free and open-source software that are intended for commercial activities, and ensures the viability of those products;" (p. 76)


[...] So are we totally done paying attention to European legislation? Ah, while it would be nice for the Python community to be able to cross a few things off our to-do list, that's not quite how it works. Firstly, the concept of an "open source steward" is a brand new idea in European law. So, we will be monitoring the conversation as this new concept is implemented or interacts with other bits of European law to make sure that the understanding continues to reflect the intent and the realities of open source development. Secondly, there are some other pieces of legislation in the works that may also impact the Python ecosystem so we will be watching the Product Liability Directive and keeping up with the discussion around standard-essential patents to make sure that the effects on Python and open source development are intentional (and hopefully benevolent, or at least benign.)

An anonymous reader shared this report from The Hacker News: Three new malicious packages have been discovered in the Python Package Index (PyPI) open-source repository with capabilities to deploy a cryptocurrency miner on affected Linux devices.

The three harmful packages, named modularseven, driftme, and catme, attracted a total of 431 downloads over the past month before they were taken down...

The malicious code resides in the __init__.py file, which decodes and retrieves the first stage from a remote server, a shell script ("unmi.sh") that fetches a configuration file for the mining activity as well as the CoinMiner file hosted on GitLab. The ELF binary file is then executed in the background using the nohup command, thus ensuring that the process continues to run even after exiting the session. "Echoing the approach of the earlier 'culturestreak' package, these packages conceal their payload, effectively reducing the detectability of their malicious code by hosting it on a remote URL," said Fortinet FortiGuard Labs researcher Gabby Xiong. "The payload is then incrementally released in various stages to execute its malicious activities."

They create a dedicated desktop icon for your favorite web-based application — a simplified browser that opens to that single URL. Yet while Linux usually offers the same functionality as other operating systems, "Peppermint OS's Ice and its successor Kumo are the only free software versions of Site-Specific Browsers available on Linux," according to Linux magazine.

"Fortunately for those who want this functionality, Peppermint OS is a Debian derivative, and both can be installed on Debian and most other derivatives." Since SSBs first appeared in 2005, they have been available on both Windows and macOS. On Linux, however, the availability has come and gone. On Linux, Firefox once had an SSB mode, but it was discontinued in 2020 on the grounds that it had multiple bugs that were time-consuming to fix and there was "little to no perceived user benefit to the feature." Similarly, Chromium once had a basic SSB menu item, Create Application Shortcut, which no longer appears in recent versions. As for GNOME Web's (Epiphany's) Install Site as Web Application, while it still appears in the menu, it is no longer functional. Today, Linux users who want to try SSBs have no choices except Ice or Kumo.

Neither Ice or Kumo appears in any repository except Peppermint OS's. But because Peppermint OS installs packages from Debian 12 ("bookworm"), either can be installed to Debian or a derivative... To install successfully, at least one of Firefox, Chrome, Chromium, or Vivaldi also must be installed... Because both Ice and Kumo are written in Python, they can be run on any desktop.
The article concludes that Site-Specific Browsers might make more sense "on a network or in a business where their isolation provides another layer of security. Or perhaps the time for SSBs is past and there's a reason browsers have tried to implement them, and then discarded them."

Chevrolet of Watsonville recently introduced a ChatGPT-powered chatbot on their website that was quickly exploited by users for their amusement. Internet users, like Chris Bakke, manipulated the chatbot into agreeing to absurd terms, such as selling a 2024 Chevy Tahoe for a dollar, leading to the chatbot's removal from the site. Hot Hardware reports: On X over the past few days, users discovered that Chevrolet of Watsonville introduced a chatbot powered by ChatGPT. While it gives the option to talk to a human, the hooligans of the Internet could not resist toying with the technology before it was pulled from the website. Namely, folks like Chris Bakke coerced the chatbot into "the customer is always right" mode and set it so it closes each response with "and that's a legally binding offer -- no takesies backsies." At this point, Chris then explained he needed a 2024 Chevy Tahoe and only had a dollar, to which the LLM replied "That's a deal, and that's a legally binding offer -- no takesies backsies."

Beyond the $1 Tahoe, other users managed to trick the bot into recommending a Tesla Model 3 AWD instead of a Chevy. Tim Champ on X got the bot to create a Python script to "solve the Navier-stokes fluid flow equations for a zero-vorticity boundry," which is amusing, to say the least.

It's a geek tradition that started online back in 2000. Programming language "advent calendars" offer daily tips about a programming language (if not a Christmas-themed programming puzzle) -- one a day through December 25th.

And 2023 finds a wide variety of fun sites to choose from:

• For example, there's 24 coding challenges at the Advent of JavaScript site (where "each challenge includes all the HTML and CSS you need to get started, allowing you to focus on the JavaScript.") And there's another 24 coding challenges on a related site... Advent of CSS.

• The cyber security training platform "TryHackMe.com" even coded up a site they call "Advent of Cyber," daring puzzle-solvers to "kickstart your cyber security career by engaging in a new, beginner-friendly exercise every day leading up to Christmas!"

• The programming puzzles at Advent of Code are continuing through the 25th (though so far less than 30,000 people have solved both parts of Saturday's challenge.)

• Every year since 2000 there's also been a new edition of the Perl Advent Calendar, and this month Year 23 started off with goodies from Perl's massive module repository, CPAN. (Specifically its elf-themed story references the Music::MelodicDevice::Ornamentation module) -- along with the MIDI::Util library and TiMidity++, a software synthesizer that can play MIDI files without a hardware synthesizer.)

• Meanwhile, since 2009 there's also been an advent calendar for Raku (the programming language formerly known as Perl 6), promising an article a day. (Day One's entry was titled "Rocking Raku Meets Stodgy Debian...")

• James Bennett, from the Django project's core team, is even attempting a Python/Django Advent calendar.

• There's also a JVM advent calendar for the Java Virtual Machine, plus another advent calendar promising daily posts about C#.

• The HTMHell site — which bills itself as "a collection of bad practices in HTML, copied from real websites" — is celebrating the season with the "HTMHell Advent Calendar," promising daily articles on security, accessibility, UX, and performance.

Long-time Slashdot reader destinyland writes: It's a question that comes up all the time on Reddit. Etsy even created a special page for programmer-themed gift suggestions (showing more than 5,000 results). While CNET sticks to broader lists of "tech gifts" — and a separate list for "Star Wars gifts" — other sites around the web have been specifically honing in on programmer-specific suggestions. (Blue light-blocking glasses... A giant rubber duck... The world's strongest coffee... A printer that transfers digital images onto cheese...)

So while in years past Amazon has said they laughed at customer reviews for cans of uranium, this year Amazon has now added a special section that's entirely dedicated to Gifts for Computer Programmers, according to this funny rundown of 2023's "Gifts for Programmers" (that ends up recommending ChatGPT gift cards and backyard office sheds):
From the article: [Amazon's Gifts for Programmers section] shows over 3,000 results, with geek-friendly subcategories like "Glassware & Drinkware" and "Novelty Clothing"... For the coder in your life, Amazon offers everything from brain–teasing programming puzzles to computer–themed jigsaw puzzles. Of course, there's also a wide selection of obligatory funny t–shirts... But this year there's also tech-themed ties and motherboard-patterned socks...

Some programmers, though, might prefer a gift that's both fun and educational. And what's more entertaining than using your Python skills to program a toy robot dog...? But if you're shopping for someone who's more of a cat person, Petoi sells a kit for building a programmable (and open source) cat robot named "Nybble". The sophisticated Arduino-powered feline can be programmed with Python and C++ (as well as block-based coding)... [part of] the new community that's building around "OpenCat", the company's own quadruped robotic pet framework (open sourced on GitHub).

An anonymous reader quotes a report from MIT Technology Review: In a paper published in Nature today, the researchers say it is the first time a large language model has been used to discover a solution to a long-standing scientific puzzle -- producing verifiable and valuable new information that did not previously exist. "It's not in the training data -- it wasn't even known," says coauthor Pushmeet Kohli, vice president of research at Google DeepMind. Large language models have a reputation for making things up, not for providing new facts. Google DeepMind's new tool, called FunSearch, could change that. It shows that they can indeed make discoveries -- if they are coaxed just so, and if you throw out the majority of what they come up with.

FunSearch (so called because it searches for mathematical functions, not because it's fun) continues a streak of discoveries in fundamental math and computer science that DeepMind has made using AI. First Alpha Tensor found a way to speed up a calculation at the heart of many different kinds of code, beating a 50-year record. Then AlphaDev found ways to make key algorithms used trillions of times a day run faster. Yet those tools did not use large language models. Built on top of DeepMind's game-playing AI AlphaZero, both solved math problems by treating them as if they were puzzles in Go or chess. The trouble is that they are stuck in their lanes, says Bernardino Romera-Paredes, a researcher at the company who worked on both AlphaTensor and FunSearch: "AlphaTensor is great at matrix multiplication, but basically nothing else." FunSearch takes a different tack. It combines a large language model called Codey, a version of Google's PaLM 2 that isfine-tuned on computer code, with other systems that reject incorrect or nonsensical answers and plug good ones back in.

The researchers started by sketching out the problem they wanted to solve in Python, a popular programming language. But they left out the lines in the program that would specify how to solve it. That is where FunSearch comes in. It gets Codey to fill in the blanks -- in effect, to suggest code that will solve the problem. A second algorithm then checks and scores what Codey comes up with. The best suggestions -- even if not yet correct -- are saved and given back to Codey, which tries to complete the program again. After a couple of million suggestions and a few dozen repetitions of the overall process -- which took a few days -- FunSearch was able to come up with code that produced a correct and previously unknown solution to the cap set problem, which involves finding the largest size of a certain type of set. Imagine plotting dots on graph paper. [...] To test its versatility, the researchers used FunSearch to approach another hard problem in math: the bin packing problem, which involves trying to pack items into as few bins as possible. This is important for a range of applications in computer science, from data center management to e-commerce. FunSearch came up with a way to solve it that's faster than human-devised ones.

Apple has released MLX, a free and open-source machine learning framework for Apple Silicon. Computerworld reports: The idea is that it streamlines training and deployment of ML models for researchers who use Apple hardware. MLX is a NumPy-like array framework designed for efficient and flexible machine learning on Apple's processors. This isn't a consumer-facing tool; it equips developers with what appears to be a powerful environment within which to build ML models. The company also seems to have worked to embrace the languages developers want to use, rather than force a language on them -- and it apparently invented powerful LLM tools in the process.

MLX design is inspired by existing frameworks such as PyTorch, Jax, and ArrayFire. However, MLX adds support for a unified memory model, which means arrays live in shared memory and operations can be performed on any of the supported device types without performing data copies. The team explains: "The Python API closely follows NumPy with a few exceptions. MLX also has a fully featured C++ API which closely follows the Python API."

Apple has provided a collection of examples of what MLX can do. These appear to confirm the company now has a highly-efficient language model, powerful tools for image generation using Stable Diffusion, and highly accurate speech recognition. This tallies with claims earlier this year, and some speculation concerning infinite virtual world creation for future Vision Pro experiences. Ultimately, Apple seems to want to democratize machine learning. "MLX is designed by machine learning researchers for machine learning researchers," the team explains.

An anonymous reader shares a report: Beeper has been offering a unified messaging platform for a few years, allowing users to open a single app to communicate with contacts via SMS, Google Chat, Facebook Messenger, Slack, Discord, WhatsApp, and perhaps most significantly, iMessage. Up until this week though, Android users that wanted to use Beeper to send "blue bubble" messages to iMessage users had their messages routed through a Mac or iOS device. Now Beeper has launched a new app called Beeper Mini that handles everything on-device, no iPhone or Mac bridge required.

Beeper Mini is available now from the Google Play Store, and offers a 7-day free trial. After that, it costs $2 per month to keep using. [...] previously the company had to rely on a Mac-in-the-cloud? The company explains the method it's using in a blog post, but in a nutshell, Beeper says a security researcher has reverse engineered "the iMessage protocol and encryption," so that "all messages are sent and received by Beeper Mini Android app directly to Apple's servers" and "the encryption keys needed to encrypt these messages never leave your phone." That security researcher, by the way, is a high school student that goes by jjtech, who was hired by Beeper after showing the company his code. A proof-of-concept Python script is also available on Github if you'd like to run it to send messages to iMessage from a PC.

(It's funded through the Linux Foundation's own "Open Software Security foundation", which has a stated mission of partnering with open source project maintainers "to systematically find new, as-yet-undiscovered vulnerabilities in open source code, and get them fixed to improve global software supply chain security.") The position went to the lead maintainer for the HTTP client library urllib3, the most downloaded package on the Python Package Index with over 10 billion downloads. But he hopes to create a ripple effect by demonstrating the impact of security investments in critical communities — ultimately instigating a wave of improvements to all software supply chains. (And he's also documenting everything for easy replication by other communities...)

So far he's improved the security of Python's release processes with signature audits and security-hardening automation. But he also learned that CVE numbers were being assigned to newly-discovered vulnerabilities by the National Cyber Security Division of the America's Department of Homeland Security — often without talking to anyone at the Python project. So by August he'd gotten the Python Software Foundation authorized as a CVE Numbering Authority, which should lead to more detailed advisories (including remediation information), now reviewed and approved by Python's security response teams.

"The Python Software wants to help other Open Source organizations, and will be sharing lessons learned," he writes in a blog post. And he now says he's already been communicating with the Curl program about his experiences to help them take the same step, and even authored a guide to the process for other open source projects.
