Diffsitter – A Tree-sitter based AST difftool to get meaningful semantic diffs

diffsitter Disclaimer diffsitter is very much a work in progress and nowhere close to production ready (yet). Contributions are always welcome! Summary diffsitter creates semantically meaningful diffs that ignore formatting differences like spacing. It does so by computing a diff on the AST (abstract syntax tree) of a file rather than computing the diff on the text contents of the file. diffsitter uses the parsers from the tree-sitter project to parse source code. As such, the languages sup

Seven Engineers Suspended After $2.3M Bridge Includes 90-Degree Turn

Ever had to make a 90-degree turn on a bridge? No? That’s the problem. In India, seven engineers just got suspended for designing exactly that. A brand-new $2.3 million bridge in Bhopal, India, is going viral—not because it solved traffic, but because it bends at nearly a 90-degree angle. Now, seven engineers have been suspended, a retired official is facing investigation, and the construction firms behind the project have been blacklisted.

Measuring the Impact of AI on Experienced Open-Source Developer Productivity

We conduct a randomized controlled trial (RCT) to understand how early-2025 AI tools affect the productivity of experienced open-source developers working on their own repositories. Surprisingly, we find that when developers use AI tools, they take 19% longer than without—AI makes them slower. We view this result as a snapshot of early-2025 AI capabilities in one relevant setting; as these systems continue to rapidly evolve, we plan on continuing to use this methodology to help estimate AI accel

Superman Movies, Ranked

It took about 40 years from Superman first gracing the pages of a comic book to finally getting his own, full-fledged live-action blockbuster. In the 40 years since that, the Man of Steel has appeared on the big screen nine times, if you include this week’s latest iteration by James Gunn. By that math, we may be in for many, many more Superman movies over the next few decades. So, before that does or doesn’t happen, we thought it would be time to put them up against each other. Below, we have o

Ars Live recap: Climate science in a rapidly changing world

The conversation then moved to the record we have of the Earth's surface temperatures and the role of Berkeley Earth in providing an alternate method of calculating those. While the temperature records were somewhat controversial in the past, those arguments have largely settled down, and Berkeley Earth played a major role in helping to show that the temperature records have been reliable. Lately, those temperatures have been unusually high, crossing 1.5° C above pre-industrial conditions for t

As X loses its CEO, daily usage is down and competition is growing

Underwater turbine spinning for 6 years off Scotland's coast is a breakthrough

Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years to harness the power of ocean tides for electricity — a durability mark that demonstrates the technology’s commercial viability. Keeping a large, or grid-scale, turbine in place in the harsh sea environment that long is a record that helps pave the way for bigger tidal energy farms and makes it far more appealing to investors, according to the trade association Ocean Energy

The First ‘Red Sonja’ Trailer Feels Like an Early Aughts Throwback

10 ways an IT home lab can help you land your next job - and how to get started (it's easy!)

EschCollection/Getty Images When I was a kid, my home lab consisted of test tubes and beakers, sodium bicarbonate (baking soda), acetic acid (vinegar), and the occasional boom, followed closely by the sound of my mom in the distance yelling, "David Allen Gewirtz, you stop that right now." When the scold transitioned from "David Gewirtz" to "David Allen Gewirtz," I knew I was in trouble. To be fair, nothing prepared my nontechnical mom and dad to raise a future engineer. I was forever taking th

Could a Paper Plane Thrown from the ISS Survive the Flight?

Luckily, that third one has finally been answered, because of course someone would eventually. A new paper from Maximilien Berthet and Kojiro Suzuki from the University of Tokyo looks at "the dynamics of an origami space plane during Earth atmospheric reentry" – in ot

Lego’s Transforming Soundwave Actually Makes Some Noise

Cloning Came to Polo. Then Things Got Truly Uncivilized

To play polo at the highest level, you have to love horses or be filthy rich. Ideally both. A team might field around 40 ponies for each game and draw on a roster of hundreds of potentially playable horses for each tournament. In the gaps between tournaments, top players scour the globe for new equine talent—trying to snaffle foals from elite bloodlines or looking to ex-racehorses to uncover a polo star in the rough. Andrey Borodin, the billionaire patron of Park Place Polo, wears the No. 1 jer
