Writing a C compiler in 500 lines of Python (2023)

Writing a C compiler in 500 lines of Python Posted August 30, 2023 A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python , after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog post , so I'll just give an ove

‘007 First Light’ Looks Like Bond’s Promising Return to Gaming

A few months ago, we got our first look at 007 First Light, the first James Bond video game in over a decade. Now that we know we’ll be playing a young 20-something Bond on the path to earning his license to kill and 00 status, developer IO Interactive has given its latest project a fuller reveal ahead of its March 2026 launch. First Light contains a blend of action and stealth gameplay with moments of opportunity for Bond (voiced by Patrick Gibson of Dexter: Original Sin) to be a sneaky secret

Poor man's bitemporal data system in SQLite and Clojure

On trying to mash up SQLite with ideas stolen from Accountants, Clojure, Datomic, XTDB, Rama, and Local-first-ers, to satisfy Henderson's Tenth Law. Viz., to make a sufficiently complicated data system containing an ad-hoc, informally-specified, bug-ridden, slow implementation of half of a bitemporal database. Because? Because laying about on a hammock, contemplating hopelessly complected objects like Current Databases isn't just for the Rich man. Don't try this at work! The "Poor Man's Bitemp

Court reinstates fired FTC Democrat, says Trump ignored Supreme Court precedent

A Democrat who was fired from the Federal Trade Commission by President Trump was reinstated to her position yesterday in an appeals court ruling. Trump's firing of Commissioner Rebecca Kelly Slaughter violated Supreme Court precedent, said yesterday's ruling from the US Court of Appeals for the District of Columbia Circuit. A District Court judge ruled the same way in July, but Slaughter couldn't get back to work because of an administrative stay that delayed the lower-court ruling from taking

Why the US government is taking a stake in Intel

The Trump administration wants the United States to be the dominant force when it comes to artificial intelligence, and one way the administration hopes to achieve primacy is by bringing semiconductor manufacturing back to the U.S. To help with that transition, President Donald Trump has introduced potential chip tariffs and policies in recent months meant to bring more semiconductor manufacturing stateside. In late August, the Trump administration took an unprecedented step toward that goal w

reMarkable announces new Paper Pro Move: a palm-sized paper tablet that’s priced well

The First Trailer for ’28 Years Later: The Bone Temple’ Expands the Zombie-Infested World

If the first trailer for 28 Years Later: The Bone Temple was just the words “Aren’t you excited you only had to wait three months to see this footage?” it would be enough. The fact is, in modern Hollywood, it’s incredibly rare for a movie to come out in June and for its sequel to be heading to theaters six months later, in January. But that’s what happened with 28 Years Later and its sequel, 28 Years Later: The Bone Temple, which will be out January 16, 2026. And, lucky for us, the trailer is mu

ReMarkable Paper Pro Move Review: A Small Yet Mighty Digital Notebook

I love a list. I can happily write the same to-do list in six different places in a single day (good thing I test digital notebooks and paper planners). I often find myself rewriting the little brainstorms in my Notes app because the ideas are still banging around in my brain, asking to be let free onto a page, digital or not. But not every brainstorm or list needs a full-size page. That's where ReMarkable's latest digital notebook comes in. The reMarkable Paper Pro Move ($449) takes the same t
