40k-Year-Old Symbols in Caves Worldwide May Be the Earliest Written Language

We may take it for grant­ed that the ear­li­est writ­ing sys­tems devel­oped with the Sume­ri­ans around 3400 B.C.E. The archae­o­log­i­cal evi­dence so far sup­ports the the­o­ry. But it may also be pos­si­ble that the ear­li­est writ­ing sys­tems pre­date 5000-year-old cuneiform tablets by sev­er­al thou­sand years. And what’s more, it may be pos­si­ble, sug­gests pale­oan­thro­pol­o­gist Genevieve von Pet­zinger, that those pre­his­toric forms of writ­ing, which include the ear­li­est known h

Understanding Deflate

Understanding Deflate I’m trying to understand how Deflate works so decided to compress a simple string TOBEORNOTTOBEORTOBEORNOT using GZIP then decode the resulting file by hand. Compressing the data Pretty simple here, text in bytes out: $ echo -n 'TOBEORNOTTOBEORTOBEORNOT' | gzip -n | xxd -ps -u 1F8B08000000000000030BF17772F50FF2F30F09013342605C00F14E3D2D 18000000 Reading the GZIP data Even though I’m really interested in the compressed data I have to decode the GZIP “wrapper” in order

Marvel Is Ready to Make Knull Happen Again

Since he first debuted as the big bad of Donny Cates and Ryan Stegman’s Venom run, Marvel’s been giving symbiote god Knull a bigger spotlight. Between his King in Black event, being a seasonal villain in Marvel Rivals, and his appearance in Venom: The Last Dance, it’s clear the publisher wants to put him in the same tier as Green Goblin or Thanos. Now, in its biggest move to build the baddie up yet, the publisher is giving the gooey baddie a solo story ahead of a larger event on the horizon. Sp

Oura rolls out new features for pregnancy and perimenopause

One downside to a fitness trackers is that they’re rarely able to understand the context in which their users live. It’s an issue Oura is looking to remedy by launching two sets of features intended to help people during pregnancy and when they reach perimenopause. Given both processes are liable to take a toll, causing physical, mental and emotional changes, having a smart ring that understands what’s going on is vital. For the former, the Oura app will now monitor your biometrics throughout p

Apple's history is hiding in a Mac font

Rome wasn't built in a day, and the same is true of desktop operating systems. The modern versions of Windows, macOS, and Linux we know and (sometimes) love today represent decades of iteration and overhauls, but much of that legacy is invisible. New design languages and interfaces show up every few years, and in the process, old applications and designs are covered up or replaced. It doesn't take long to find legacy holdovers in today's Windows 11—for example, that Windows 3.1-era file picker

A Deadly Outbreak of Legionnaires’ Disease Is Hitting NYC

A deadly outbreak of Legionnaires’ disease is ripping through Central Harlem in New York City. Local health officials report that about two dozen residents have been sickened by the pneumonia-causing bacteria so far this month. The NYC Health Department issued its latest update on the outbreak Wednesday, following its first report last week. Since July 25, there have been 22 cases of Legionnaires’ disease diagnosed throughout the area, along with one death. Residents in the affected neighborhoo

Asymmetry of verification and verifier's law

Asymmetry of verification is the idea that some tasks are much easier to verify than to solve. With reinforcement learning (RL) that finally works in a general sense, asymmetry of verification is becoming one of the most important ideas in AI. Understanding asymmetry of verification through examples Asymmetry of verification is everywhere, if you look for it. Some prime examples: Sudoku and crossword puzzles take a lot of time to solve because you have to try many candidates against various c

What Is Pruritus? What the FDA Warning About Xyzal and Zyrtec Side Effects Means

When that allergy season hits, it's normal to reach for your medication to try and get through your day. An FDA estimate says that 62.7 million over-the-counter packages of Zyrtec (cetirizine) and Xyzal (levocetirizine) were sold in 2022. We're now in an era where climate change is making for longer, more intense pollen seasons, which is partly responsible for allergies getting worse. The sales figures have likely climbed in the last three years, with worsened allergy symptoms like a runny nose,

Open, free, and ignored: the afterlife of Symbian

The result of the pioneering joint Psion and Nokia smartphone effort is still out there on GitHub. Smartphones are everywhere. They are entirely commoditized now. Most of them run Android, which uses the Linux kernel. The rest run Apple's iOS, which uses the same XNU kernel as macOS. As we've said before, they're not Unix-like, they really are Unix™. There have been a bunch of others. BlackBerry tried hard with BB10, but even a decade ago, it was over. It was based on QNX and Qt, and both of t

Traditional Chinese Medicine Has Not Been Vindicated by Science

People love to show that skeptics were wrong about something, especially when national pride hangs in the balance. The South China Morning Post published the following headline on November 3rd: “Scientists find traditional Chinese medicine is based on a complex network of proteins – 3,000 years before modern science.” The article points out that respectable editorials in the scientific literature had repeatedly referred to traditional Chinese medicine (TCM) as “largely just pseudoscience” and “

QRS: Epsilon Wrangling

I haven’t shipped any new features for Quamina in many months, partly due to a flow of real-life distractions, but also I’m up against tough performance problems in implementing Regular Expressions at massive scale. I’m still looking for a breakthrough, but have learned things about building and executing finite automata that I think are worth sharing. This piece has to do with epsilons; anyone who has studied finite automata will know about them already, but I’ll offer background for those peop

Which operating system was targeted by the first ever mobile phone virus?

Choose wisely! The correct answer, the explanation, and an intriguing story await. Correct Answer: Symbian Before becoming the iconic star of Super Mario Bros., what was Mario originally named? The first known mobile phone virus was Cabir, also referred to as Caribe. Discovered in June 2004 by Kaspersky Lab, Cabir primarily targeted mobile devices running the Symbian operating system, an OS widely used in Nokia phones during the early 2000s. Although the virus itself was not overtly malicious

Tick Bite? Here's What to Know About Lyme Disease and Your Next Steps

You just finished a satisfying summer hike or wrapped up a weekend of yard work when you spot a tick clinging to your clothes. The fresh-air high fades quickly as you remember the risks -- ticks are known carriers of Lyme disease, a growing concern across the US. Lyme disease cases have more than doubled in recent years, according to the CDC, with annual reports jumping from around 42,000 to nearly 90,000. While part of that increase is due to improved detection and reporting methods, the risk

Bzip2 crate switches from C to 100% Rust

Today we published bzip2 version 0.6.0 , which uses our rust implementation of the bzip2 algorithm, libbz2-rs-sys , by default. The bzip2 crate is now faster and easier to cross-compile. The libbz2-rs-sys crate can also be built as a C dynamic library, if you have a C project that would benefit from these improvements. Why though? Why bother working on this algorithm from the 90s that sees very little use today? The thing is that many protocols and libraries still need to support bzip2 to be

Me an' Algernon – grappling with (temporary) cognitive decline

Originally published May 20, 2015. Since then my cognitive function has made a fairly complete comeback, well except accounting for normal aging. I was reminded of this essay by my experience with augmented coding. That “normal aging” stuff left me without the patience to get set up for coding. With the genie, though, I’m happy to dive into most any project. It’s like wearing an exoskeleton but for my brain. The point remains—don’t take cognition for granted. If you’re augmented coding & you wa

Whatever Happened to Sandboxfs?

Back in 2017–2020, while I was on the Blaze team at Google, I took on a 20% project that turned into a bit of an obsession: sandboxfs. Born out of my work supporting iOS development, it was my attempt to solve a persistent pain point that frustrated both internal teams and external users alike: Bazel’s poor sandboxing performance on macOS. sandboxfs was a user-space file system designed to efficiently create virtual file hierarchies backed by real files—a faster alternative to the “symlink fore
