Was This the Geekiest Concert of All Time?

When the hamburger-shaped spaceship with the word “Millennium” on the back lowered down above me, I figured I was in for something special. What I didn’t expect was that, for the next two hours, the “Millennium…” let’s call it “Falcon,” would fly through an asteroid field before docking on a planet with light cycles and noir landscapes, as lines of code dropped down like rain and huge cylindrical gates of stars swirled around. But that’s what happened, and, I must say, it was phenomenal. Last w

Regarding Prollyferation: Followup to "People Keep Inventing Prolly Trees"

Last month I published a blog post about the parallel invention of Prolly Trees, where I observed the repeated independent invention of a certain type of data structure within a relatively short period of time. In short, I described the concept of a Merkle Tree created by applying a content-defined chunker to a file, hashing the chunks, and then recursively reapplying the chunker to the concatenated list of hashes until only a single chunk remained. Each iteration of this process defined a sepa

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

Tree Borrows

The Rust programming language is well known for its ownership-based type system, which offers strong guarantees like memory safety and data race freedom. However, Rust also provides unsafe escape hatches, for which safety is not guaranteed automatically and must instead be manually upheld by the programmer. This creates a tension. On the one hand, compilers would like to exploit the strong guarantees of the type system—particularly those pertaining to aliasing of pointers—in order to unlock powe

Apple’s newest AI study unlocks street navigation for blind users

There’s no shortage of rumors about Apple’s plans to release camera-equipped wearables. And while it’s easy to get fatigued by yet another wave of upcoming AI-powered hardware, one powerful use case often gets lost in the shuffle: accessibility. SceneScout, a new research prototype from Apple and Columbia University, isn’t a wearable. Yet. But it hints at what AI could eventually unlock for blind and low-vision users. As Apple’s and Columbia University’s researchers explain it: People who are

Bcachefs may be headed out of the kernel

Bcachefs may be headed out of the kernel The history of the bcachefs filesystem in the kernel has been turbulent, most recently with Linus Torvalds refusing a pull request for the 6.16-rc3 release. Torvalds has now pulled the code in question, but also said: I think we'll be parting ways in the 6.17 merge window. You made it very clear that I can't even question any bug-fixes and I should just pull anything and everything. Honestly, at that point, I don't really feel comfortable being involved

Dr. Phil’s ‘Anti-Woke’ TV Network Files for Bankruptcy After Only a Year

Last year, in an effort to capitalize on anti-woke backlash, Dr. Phil (real name Phil McGraw) launched his own TV channel, which he said would be used to fight the good fight against the far left’s radical crazies. Merit Street Media, according to McGraw, would be a vanguard in the battle for the soul of America. “Merit Street Media will be a resource of information and strategies to fight for America and its families, which are under a cultural ‘woke’ assault as never before,” said McGraw at t

There's no such thing as a tree (phylogenetically) (2021)

So you’ve heard about how fish aren’t a monophyletic group? You’ve heard about carcinization, the process by which ocean arthropods convergently evolve into crabs? You say you get it now? Sit down. Sit down. Shut up. Listen. You don’t know nothing yet. “Trees” are not a coherent phylogenetic category. On the evolutionary tree of plants, trees are regularly interspersed with things that are absolutely, 100% not trees. This means that, for instance, either: The common ancestor of a maple and a m

Graph Theory Applications in Video Games

Maze Generation w/ Disjoint-Sets & Union-Find Observing Properties of Mazes Cells are "matched" with a select few adjacent ones. Cells that have been matched do not have a wall between them. All cell pairs that are not "matched" have a wall separating them. Mazes can be represented as graphs. Depending on the properties of the maze, it can be a minimum spanning tree. We can use typical graph algorithms to find solutions to mazes. Popular choices include DFS (Depth-First Search)

People Keep Inventing Prolly Trees

Multiple Discovery refers to when a scientific discovery is made independently by multiple individuals around the same time. The most well-known examples are Isaac Newton and Gottfried Leibniz's independent invention of calculus, and Charles Darwin and Alfred Russel Wallace's independent formulation of the theory of evolution. (Source: https://xkcd.com/626/) There's even a hypothesis that multiple discovery is the norm, rather than an exception: that invention is an result of social conditions

The European wood pigeon helped me appreciate its omnipresent city cousins

As I read more about the Columbidae, though, I came to appreciate pigeons for more than just their beauty. Their big appetites are crucial to the health of forests around the globe. Researchers observing fig trees in Malaysia once found that green pigeons consumed far more fruit than any other animal in the jungle, visiting some trees more often than all other animals combined. Most animals defecate seeds near the parent tree, but pigeons are long-distance fliers who retain seeds in their guts l

Google Earth just made time travel easier - here's how to visit the old neighborhood

US Streetlights Are Turning Purple

American cities and towns started switching their streetlights from sodium lamps to LEDs about 15 years ago, which changed the color of many nighttime roads from yellowish orange to bright white. But lately an odd new nocturnal color has been spotted across the nation—and the globe. Anecdotal reports of purple-looking streetlights have been popping up since early 2021 in states including Florida, Utah, Texas and Massachusetts, as well as in Canada and Ireland. This phenomenon might seem weird b

Sparse Voxels Rasterization: Real-Time High-Fidelity Radiance Field Rendering

Our scene representation is a hybrid of primitive and volumetric model. (a) Primitive component. We explicitly allocate voxels primitives to cover different scene level-of-details under an Octree layout. Note that we do not replicate a traditional Octree data structure with parent-child pointers or linear Octree. We only keep voxels at the Octree leaf nodes without any ancestor nodes. (b) Volumetric component. Inside a voxel is a volumetric (trilinear) density field and a (constant) spherical ha
