Lisp-stat: Lisp environment for statistical computing

Lisp-Stat is conceptually similar to R and will be familiar to most people from that ecosystem. It is suitable for both exploratory data analysis as well as front-line production deployments. Common Lisp is currently used at Google in several high-availability, high-volume transactional systems. Why Lisp? We had a few requirements when evaluating options. Specifically the system had to: Work well in the kind of exploratory environment conducive to analytics and AI Be robust enough to work in

Jokes and Humour in the Public Android API

Jokes and Humour in the public Android API Previously I have covered a relatively obscure now-removed placeholder string in Android that doubles as an easter egg, the fictitious carrier by the name of El Telco Loco. But this time it is about methods and other parts of the publicly facing Android API that may generally be more humourous than they are useful. Easter eggs, jokes, whatever you want to call them, that are visible to Android app developers rather than regular users. ActivityManager.

Start your own Internet Resiliency Club

Thanks to war, geopolitics, and climate change, Europe will have more frequent and more severe internet disruptions in the very near future. Governments and businesses need to prepare for catastrophic loss of communications. Unfortunately, the necessary changes are risky and expensive, which means they won’t do it until a crisis is already here. However, small groups of volunteers with a little bit of time and money can provide crucial initial leadership to bootstrap recovery. An Internet Resil

The Switch 2 Proves Nintendo Never Misses on Music

Nintendo is a lot of things to a lot of people for a lot of different reasons. Mario helps, and so do the host of other iconic first-party titles and the movies, toys, theme parks, and endless other IP offshoots they spawned. But beyond how Nintendo looks and plays and sells, it also has a sound, and thanks to the Switch 2, that sound is just as iconic as ever this time around. Seriously, though, listen to the Mario Kart World soundtrack right now. There’s a lot of newfangled Switch 2 music I l

Anker’s Soundcore Sleep earbuds finally feature active noise canceling

is a senior reporter who’s been covering and reviewing the latest gadgets and tech since 2006, but has loved all things electronic since he was a kid. Anker has announced a new version of its wireless sleep buds that could be even more effective at delivering a peaceful slumber by blocking out disturbing noises using active noise cancellation. Previous versions of the Soundcore Sleep earbuds blocked external sounds passively using just a snug fit inside the ear, but the new Sleep A30 finally ad

The U.S. Navy is more aggressively telling startups, ‘We want you’

While Silicon Valley executives like those from Palantir, Meta, and OpenAI are grabbing headlines for trading their Brunello Cucinelli vests for Army Reserve uniforms, a quieter transformation has been underway in the U.S. Navy. How so? Well, the Navy’s chief technology officer, Justin Fanelli, says he has spent the last two and a half years cutting through the red tape and shrinking the protracted procurement cycles that once made working with the military a nightmare for startups. The efforts

Aspora gets $50M from Sequioa to build remittance and banking solutions for Indian diaspora

India has been one of the top recipients of remittances in the world for more than a decade. Inward remittances jumped from $55.6 billion in 2010-11 to $118.7 billion in 2023-24, according to data from the country’s central bank. The bank projects that figure will reach $160 billion in 2029. This means there is an increasing market for digitalized banking experiences for non-resident Indians(NRIs), ranging from remittances to investing in different assets back home. Aspora (formerly Vance) is

Here's how to keep Meta AI from sharing your prompts on Facebook, Instagram

Artificial intelligence-generated images of women kissing while mud wrestling and President Donald Trump eating poop are some of the conversations users are unknowingly sharing publicly through Meta's newly launched AI app. The company rolled out the Meta AI app in April, putting it in direct competition with OpenAI's ChatGPT. But the tool has recently garnered some negative publicity and sparked privacy concerns over some of the wacky — and personal — prompts being shared publicly from user ac

Stanford Doctors Invent Device That Appears to Be Able to Save Tons of Stroke Patients Before They Die

Image by Andrew Brodhead Researchers have developed a novel device that literally spins away the clots that block blood flow to the brain and cause strokes. As Stanford explains in a blurb, the novel milli-spinner device may be able to save the lives of patients who experience "ischemic stroke" from brain stem clotting. Traditional clot removal, a process known as thrombectomy, generally uses a catheter that either vacuums up the blood blockage or uses a wire mesh to ensnare it — a procedure

How to set up a WhatsApp account without Facebook or Instagram

There's no shortage of reasons to stay off the Meta ecosystem, which includes Facebook and Instagram, but there are some places where WhatsApp remains the main form of text-based communication. The app is a great alternative to SMS, since it offers end-to-end encryption and was one of the go-to methods to send uncompressed photos and videos between iPhone and Android users before Apple adopted RCS. Even though Facebook, which later rebranded to Meta, acquired WhatsApp in 2014, it doesn't require

ChatGPT's AI coder Codex now lets you choose the best solution

ChatGPT's Codex, which is an AI agent that lets you code and delegate programming tasks, is now testing a new feature that lets you choose the best solution. OpenAI launched Codex in April, and it's a great tool, but it's nowhere close to replacing entry-level engineers. OpenAI insists Codex could help developers achieve more by delegating their tasks to different agents, and a new update brings it closer to the expectations set by the company. As per the release notes, ChatGPT Codex can now

Studio Ghibli marks 40 years, but future looks uncertain

Japan's Studio Ghibli turns 40 this month with two Oscars and legions of fans young and old won over by its complex plots and fantastical hand-drawn animation. But the future is uncertain, with latest hit "The Boy and the Heron" likely — but not certainly — the final feature from celebrated co-founder Hayao Miyazaki, now 84. In March, the internet was flooded with pictures in Studio Ghibli's distinctively nostalgic style after the release of OpenAI's newest image generator — raising questions o

GNOME and Red Hat Linux eleven years ago (2009)

GNOME and Red Hat Linux Eleven Years Ago By Oscar Laycock Four years ago, I switched on an old PC and found a seven year old (at that time) copy of Linux on it. I still use parts of the 1998 Red Hat Linux, today. Red Hat Linux in 1998 My copy of Red Hat Linux is 5.1, codenamed "Manhattan". It was released on May 22, 1998. The first Red Hat Linux 1.0 was released on November 3, 1994. Finally, Red Hat Linux merged with Fedora on 22 September 2003, when Red Hat started Red Hat Enterprise Linux.

Simplest C++ Callback, from SumatraPDF

SumatraPDF is a Windows GUI application for viewing PDF, ePub and comic books written in C++. A common need in GUI programs is a callback. E.g. when a button is clicked we need to call a function with some data identifying which button was clicked. Callback is therefore a combo of function and data and we need to call the function with data as an argument. In programming language lingo, code + data combo is called a closure. C++ has std::function<> and lambdas (i.e. closures). Lambdas convert

Cyborg Embryos Offer New Insights into Brain Growth

Scientists have created cyborg embryos by implanting electrode arrays into the developing brains of frogs, mice, and salamanders. Although the researchers reject implants in human embryos as unethical, they suggest their technology might one day help study and treat neurodevelopmental conditions in children. The stretchable technology at the core of the electrode arrays could record brain activity while remaining soft enough to accommodate the children’s growth. Recording the activity of neuron

The Skyscraper That Could Have Toppled over in the Wind (1995)

Within this seemingly simple computation, however, lurks a powerful multiplier. At any given level of the building, the compression figure remains constant; the wind may blow harder, but the structure doesn’t get any heavier. Thus, immense leverage can result from higher wind forces. In the Citicorp tower, the forty-per-cent increase in tension produced by a quartering wind became a hundred-and-sixty-per-cent increase on the building’s bolts. Precisely because of that leverage, a margin of safe

David Attenborough at 99: 'I will not see how the story ends'

My earliest memory of the ocean is of a tropical lagoon. Ammonites rose and fell in the warm water column, occasionally propelling themselves forwards, their curled ram’s horn shells surprisingly streamlined in the water. This tropical lagoon was in fact in my imagination, fired as I explored the old limestone quarry near my childhood home in Leicester, some 60 miles from the coast. For a small boy in the 1930s this was a marvellous place for adventures, and the knowledge that millions of year

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features

Seastar Seastar is a fast, extensible build system for C, C++, and maybe soon, Rust and Zig as well. I believe that it should be easy to make, prototype, and iterate upon designs. While C is still one of our most widely used languages, it makes it hard to create programs easily, especially for beginners. Instead, Seastar aims to be more like Rust's tooling with cargo , but supporting seamless compilation across more languages. Running Seastar is very simple to build and run. Assuming you have

Twin – A Textmode WINdow Environment

Twin - a Textmode WINdow environment Version 0.9.0 Twin is text-based windowing environment with mouse support, window manager, terminal emulator, networked clients and the ability to attach/detach mode displays on-the-fly. It supports a variety of displays: plain text terminals: Linux console, twin's own terminal emulator, and any termcap/ncurses compatible terminal; X11, where it can be used as a multi-window xterm; itself (you can display a twin on another twin); twdisplay, a general n

How fast can the RPython GC allocate?

While working on a paper about allocation profiling in VMProf I got curious about how quickly the RPython GC can allocate an object. I wrote a small RPython benchmark program to get an idea of the order of magnitude. The basic idea is to just allocate an instance in a tight loop: class A ( object ): pass def run ( loops ): # preliminary idea, see below for i in range ( loops ): a = A () a . i = i The RPython type inference will find out that instances of A have a single i field, which is an i

Datalog in miniKanren

A browser with Wasm GC and tail call support is required for this demo. We recommend using either Mozilla Firefox or Google Chrome. Datalog in miniKanren Having access to an embedded logical programming language makes some tasks really easy. One prerequisite for RealTalk is some form of Datalog, and I built one in Scheme using miniKanren so that I had access to all of the internals. This page explains the naive Datalog implementation I did before modifying some of it to fit my version of Dynam

First 2D, non-silicon computer developed

The team used metal-organic chemical vapor deposition (MOCVD) — a fabrication process that involves vaporizing ingredients, forcing a chemical reaction and depositing the products onto a substrate — to grow large sheets of molybdenum disulfide and tungsten diselenide and fabricate over 1,000 of each type of transistor. By carefully tuning the device fabrication and post-processing steps, they were able to adjust the threshold voltages of both n- and p-type transistors, enabling the construction

Telephone Exchanges in the UK

For more than a century the telephone exchange has formed the backbone of our telecommunications system. A vast array of more than 5,500 mostly nondescript buildings sit unnoticed on city, town or village streets, and quietly link up more than 254 million kilometres of cables and wires – keeping people in the UK connected to each other and the rest of the world. Since the first telephone exchange was established in London in 1879 with just eight subscribers, these anonymous looking buildings ha

It’s nearly impossible to buy an original Bob Ross painting (2021)

Bob Ross is not a hard man to find. Though he died in 1995, the late TV painter remains an omnipresent cultural staple. His Chia Pet perm, nap-inducing voice, and meme-worthy sayings — “Happy little trees!” — have transcended time. On YouTube, old episodes of his show, The Joy of Painting, boast ~450m views. Online, you can acquire Bob Ross paints, Bob Ross brushes, Bob Ross underwear, Bob Ross coffee mugs, Bob Ross energy drinks, Bob Ross watches, and Bob Ross toasters. But there’s one thing

20 Years Ago, Batman Began a New Era of Hollywood

There are plenty of constants in popular culture, and Batman is near the top of the list. He’s everywhere in some fashion, particularly in movies, and his various cinematic versions have been significant in some way that speaks to how both the audience and Warner Bros. view the character. Of those, Batman Begins may be the most important. The first chapter of an eventual trilogy from director Christopher Nolan and writers David S. Goyer and Jonathan Nolan released on June 15, 2005, and marked h

Behold, a Shadowy Full Look at the New He-Man

Amazon MGM’s upcoming Masters of the Universe movie just got a bit more real thanks another, more complete look at its musclebound lead, He-Man. Portrayed in the upcoming film by Nicolas Galtizine, the British actor released a picture of himself as Adam of Grayskull’s heroic persona, albeit from the back and bathed in shadow. The picture comes with the news that filming has wrapped, and Galtizine called it “an honour shouldering the responsibility of playing Adam and He-Man. It’s been the role
