The new Return to Silent Hill trailer gives us our first look at Pyramid Head

Nearly three years on from its original announcement, Return to Silent Hill finally has a proper trailer. It’s only 40 seconds long, but in that time we get a healthy supply of foggy and eerily empty street shots, terrifying monsters and a very brief glimpse of the iconic Pyramid Head. It looks like a Silent Hill movie alright. Return to Silent Hill is based on the 2001 survival horror classic Silent Hill 2, which got the remake treatment last year and remains one of the genre’s most important

Retry Loop Retry

Retry Loop Retry Some time ago I lamented that I don’t know how to write a retry loop such that: it is syntactically obvious that the amount of retries is bounded, there’s no spurious extra sleep after the last attempt, the original error is reported if retrying fails, there’s no code duplication in the loop. https://matklad.github.io/2023/12/21/retry-loop.html To recap, we have fn action () E ! T { ... } fn is_transient_error (err: E) bool { ... } and we need to write fn action_with_r

The Annotated Transformer (2022)

The Annotated Transformer v2022: Austin Huang, Suraj Subramanian, Jonathan Sum, Khalid Almubarak, and Stella Biderman. Original: Sasha Rush. The Transformer has been on a lot of people’s minds over the last year five years. This post presents an annotated version of the paper in the form of a line-by-line implementation. It reorders and deletes some sections from the original paper and adds comments throughout. This document itself is a working notebook, and should be a completely usable impl

Playing every game of Wordle simultaneously

If you’ve fallen far enough down the Wordle rabbit hole you may have heard of Quordle, a version of Wordle where you solve four words at once. If you’re looking for more of a challenge, Britannica has you covered with Octordle, where you solve eight words at once. And of course any Wordler worth their salt should be able to handle sixteen words, like in Sedecordle. And no, it doesn’t stop there: Sexaginta-quattuordle isn’t real, it can’t hurt yo– One logical extreme of this trend would be to

A visual introduction to big O notation

Big O notation is a way of describing the performance of a function without using time. Rather than timing a function from start to finish, big O describes how the time grows as the input size increases. It is used to help understand how programs will perform across a range of inputs. In this post I'm going to cover 4 frequently-used categories of big O notation: constant, logarithmic, linear, and quadratic. Don't worry if these words mean nothing to you right now. I'm going to talk about them

Apple accuses Android brand of trade secret theft over wearables (Update: Response)

Update: August 25, 2025 (1:07 AM ET): OPPO has now issued an official statement addressing Apple’s legal filing against it and a former Apple employee. The company posted the following in an email to Android Authority: We are aware of the recent lawsuit filed by Apple in California and have carefully reviewed the allegations in Apple’s complaint. We have found no evidence establishing any connection between these allegations and the employee’s conduct during his employment at OPPO. OPPO respec

Dynamically patch a Python function's source code at runtime

written by Eric J. Ma on | tags: In this blog post, I share how I discovered a powerful Python trick: dynamically changing a function's source code at runtime using the compile and exec functions. This technique enabled me to build more flexible AI bots, like ToolBot, that can generate and execute code with access to the current environment. While this opens up exciting possibilities for LLM-powered agents and generative UIs, it also raises serious security concerns. Curious how this hack can s

Without the futex, it's futile

Phil Eaton’s book club is starting The Art of Multiprocessor Programming, 2nd Edition , which is a very well regarded textbook, and pretty recently updated (2021). I’ve even heard of a couple of authors. I’ve done a lot of concurrent programming, and have always felt like I’ve still got plenty to learn, so I was excited for the topic. So far, what I’ve learned is that I would never recommend this book, despite any merits. Academia certainly struggles to find the right balance between teaching

UFO 50 Review: Indie Nostalgia Arrives on the Switch 2

As an older gamer, you'd think I have a fondness for retro games. But I don't. I grew up when simply playing any video game was exciting, even if the game itself was bad. UFO 50 changes that. First released last year on PC and recently ported to the Switch and Switch 2 on Aug. 7, the unique indie title flips the script with a collection of 50 "retro" games that actually never existed. UFO 50 is a collection of fictional retro games designed to look like they came out in the Apple II, Amiga and

A Lisp in 99LOC

Lisp in 99 lines of C and how to write one yourself In honor of the contributions made by Church and McCarthy, I wrote this project and the accompanying article to show how anyone can write a tiny Lisp interpreter in a few lines of C or in any "C-like" programming language for that matter. I attempted to preserve the original meaning and flavor of Lisp as much as possible. As a result, the C code in this project is strongly Lisp-like in compact form. Despite being small, these tiny Lisp interpr

In-depth analysis on Valorant's Guarded Regions

This post is not meant to be an attack towards Riot Games’ Vanguard or Microsoft’s Windows, they have done an excellent job with their products and will continue to do so for the coming years, the content of this post is gathered solely by me, and I am not tied to any game hack publisher or entities.

Lambdas, Nested Functions, and Blocks (2021)

I have the fortunate privilege to be part of the ISO C Standard mailing list, and recently a thread kicked off about Lambdas and what their need is in the C Community. That thread was in response to an ongoing push by Jens Gustedt’s proposal N2736, where Gustedt is building steam to put a proper function + data type into the C Standard at some point. What kicked off in that thread was a lot of talking about nested functions, blocks, statement expressions, whether we even need the ability to have

Microsoft is getting ready to return to the office

is a senior editor and author of Notepad , who has been covering all things Microsoft, PC, and tech for over 20 years. Microsoft originally encouraged its employees to work from home amid the coronavirus outbreak in 2020. This new flexible working arrangement then became an official “hybrid workplace” policy several months after the pandemic began, allowing managers to approve permanent remote work. Now that the pandemic has settled into endemicity, Microsoft wants employees to return to the of

Ask HN: How do you tune your personality to get better at interviews?

I just got declined for a job and it has gotten under my skin much more than it should. (Under the advisement of my lawyer (ChatGPT) I won't say the company's name). It has really annoyed me; I ended up doing three interviews over the course of four weeks, and I'm pretty confident that I got the technical questions right. It could be that my resume is too "jumpy", which is fair, but they could have read my resume before they wasted my time and theirs with three multi-hour interviews. The only

Funky new wallpaper to welcome the latest Apple Store

Apple has today previewed its latest retail store ahead of its opening on Saturday. As usual, the company has created a funky new wallpaper to celebrate the opening, and made it available for download. The store design mirrors what we have seen in other recent mall openings: a curved frontage with lots of glass, blurring the boundary between interior and exterior … Qianhai Yifang City Apple store The latest store is in Shenzhen, which is coincidentally home to a lot of Apple suppliers.

Scientists Unveil Wild New Way to Explore the Edge of Space

Scientists often refer to the mesosphere as the “ignorosphere”—a region that’s too high for planes or weather balloons to explore, yet too low for satellites to probe. Despite our technological advances, we’ve yet to find a decent way to monitor this large stretch of air, which lies about 37 miles (60 kilometers) above the surface. But engineers are inching towards a solution—one inspired by a toy-like invention from the 19th century. A Nature paper published today presents a proof-of-concept f

James Gunn’s ‘Superman’ Flies Home This Week

James Gunn’s Superman was pushed out of the top five at the box office this past weekend, marking the beginning of the end of its box office run. It’s been a good one, with over $330 million in the U.S. so far and another $250 million worldwide. It’s the highest-grossing Superman film ever, domestically not adjusted for inflation, and now the journey takes its next step. Gunn took to social media Tuesday to announce his DC Universe film will be available on digital August 15. That’s this week.

Why tail-recursive functions are loops

One story every computing enthusiast should hear is the lesson of how loops and tail-recursion are equivalent. We like recursive functions because they’re amenable to induction, and we can derive them in a way that is in direct correspondence with the definition of the datatype over which they recur. We like loops because they’re fast and make intuitive sense as long as variables don’t change in too tricky a way. In general, recursive functions are slower than loops because they push stack fram

Generic Containers in C: Safe Division Using Maybe

Generic Containers in C: Safe Division Using Maybe. Martin Uecker, 2025-08-10 I discuss the implementation of type and bounds safe generic containers in C. Previously, I discussed a span type, bounds checking using arrays. and a a vector type. This time, I will discuss maybe inspired by Haskell. This type can used to return a value that may not exist, e.g. because an error was encountered during the computation. The following examples shows for a divide function that catches division by

People returned to live in Pompeii's ruins, archaeologists say

People returned to live in Pompeii's ruins, archaeologists say New evidence suggests people returned to live among the ruins of Pompeii after the ancient Roman city was devastated by a volcanic eruption. Archaeologists believe some survivors who could not afford to start a new life elsewhere returned to the site and may have been joined by others looking for a place to settle. Pompeii was home to more than 20,000 people before Mount Vesuvius erupted in AD79, burying - and preserving - much of

Writing a storage engine for Postgres: An in-memory table access method (2023)

With Postgres 12, released in 2019, it became possible to swap out Postgres's storage engine. This is a feature MySQL has supported for a long time. There are at least 8 different built-in engines you can pick from. MyRocks, MySQL on RocksDB, is another popular third-party distribution. I assume there will be a renaissance of Postgres storage engines. To date, the efforts are nascent. OrioleDB and Citus Columnar are two promising third-party table access methods being actively developed. Why
