I Wrote a Compiler

I have a Computer Science degree. I attended a whole course of lectures on compilers (and have a certain fondness for “the red dragon book” as a result). However, I had never actually written a compiler from start to finish until a rainy day last weekend. Yes, this is what I do for fun. I wanted to make a compiler for a real language, but a simple one so I could complete the project in a few hours. I’ve always had a bit of a soft spot for BASIC - it’s the first progamming language I learned as

As Anthropic battles in global AI rankings, it’s important to note what sets it apart from other top AI labs. Since its founding in 2021, when seven OpenAI employees broke off over concerns about AI safety,

Former NASA Agent Suggests Government Used UFO Theories To Cover "Stealth Technology"

A former NASA official says he thinks the government uses rumors of alien conspiracies to hide its secrets — a suggestion corroborated by a recent bombshell report about military officials spreading UFO disinformation. In an interview with Fox News, Joseph Gutheinz, a former special agent at NASA's inspector general, said that the US military's clandestine operations are likely behind many UFO conspiracy theories. "I believe early on in the 1940s when all these UFO stories started coming up, i

What to read this weekend: Vampires and more vampires

I was pretty late in getting to this one, as it's been on my list for a good while now, but I really can't think of a better time to have finally picked up this retelling of the original sapphic vampire story, Carmilla, than during Pride Month. And what a treat it is. Hungerstone is a gothic novel that follows Lenore, a woman who has been uprooted from London and moved to the British moorlands by her husband, Henry, to fulfill his career ambitions. Henry is… not the best, and Lenore could defini

How a Cyberattack at a Company You've Never Heard of Nearly Derailed My Anniversary Carrot Cake

Every year since we got married, my husband and I have celebrated our anniversary with a carrot cake. Some years it was from the amazing bakery in our old neighborhood, while others it was a questionably fresh effort picked up at a train station shop on the way home from the office, but often I would bake my own. The funny thing is, neither of us really likes carrot cake. It just somehow ended up being the top layer of our wedding cake, so we have one every year. That's tradition for you. This

The fastest way to detect a vowel in a string

Austin Z. Henley Associate Teaching Professor Carnegie Mellon University [email protected] @austinzhenley github/AZHenley The fastest way to detect a vowel in a string 6/13/2025 I was nerdsniped recently: What is the best way to detect if a string has a vowel in it? This is trivial, right? But as I started getting into it, I realized there is much more to this. I challenged myself to come up with as many ways to detect a vowel as possible. I even asked a few friends to give it a go. Whi

Anbernic’s sliding screen handheld might be too chunky and heavy for your pockets

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. Anbernic hasn’t officially released or even put its new RG Slide handheld up for preorder yet, but a handful of reviewers have recently shared their first impressions of the new console. Anbernic may be leaning a bit too far into novelty and nostalgia with the RG Slide’s design, while not actually capitalizing on what made devices like the light

Victoria’s Secret restores critical systems after cyberattack

Victoria's Secret has restored all critical systems impacted by a May 24 security incident that forced it to shut down corporate systems and the e-commerce website. The company operates around 1,380 retail stores in nearly 70 countries and has reported net sales of $1.353 billion for the first quarter of 2025, with a forecasted net sales range of up to $6.3 billion for the year. In a Thursday filing with the U.S. Securities and Exchange Commission, the company disclosed that all restored criti

Experimental retina implants give mice infrared vision

Human vision relies on photoreceptor cells in the retina that react to visible light and trigger neurons in the optic nerve to send signals to the brain. Degradation of these photoreceptors is the leading cause of vision impairments, including blindness. However, a team of scientists at China’s Fudan University has recently built prototype retinal implants that can replace the failing photoreceptors and potentially provide infrared vision as a bonus. Sadly, they’ve only been tested in animals,

After RFK Jr. fires vaccine advisors, doctors brace for blitz on childhood shots

The medical community is bracing for attacks on, and the possible dismantling of, federal recommendations for safe, lifesaving childhood vaccinations after health secretary and fervent anti-vaccine advocate Robert F. Kennedy Jr. abruptly fired all 17 members of a federal vaccine advisory committee Monday. Outrage has been swift after Kennedy announced the "clean sweep" of the Centers for Disease Control and Prevention's vaccine advisory panel, the Advisory Committee on Immunization Practices (A

TinyCompiler: A compiler in a week-end

TinyCompiler: a compiler in a week-end Introduction Have you ever wondered how a compiler works, but you never found courage to find out? Then this series of articles is for you. I have never had the chance to look under the hood either, but one week-end I have decided to to write a translator from the esoteric programming language wend (short for week-end), which I just invented myself, into regular GNU assembly. The goal is to keep the code as tiny as possible, 500-ish lines of python sounds
