<strong>Hacking Formula 1: Accessing Max Verstappen's passport and PII through FIA bugs (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Devs discovered a vulnerability in the FIA Driver Categorisation portal that allowed them to escalate their privileges to administrator. This admin access granted them the ability to view sensitive PII, including passports and resumes, of F1 drivers like Max Verstappen. The vulnerability was reported to the FIA, which took the site offline and implemented a fix.

<strong>4 Unconventional Ways to Cast in Typescript (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
This article goes over four unconventional methods to cast between types in TypeScript, showing potential unsoundness in the language's type system. These methods include abusing the `is` operator, using mutation across boundaries, exploiting structural typing, and manipulating `void` type combinations. While TypeScript generally provides good type safety, these techniques can introduce subtle bugs and unsafety.

<strong>How Memory Maps (mmap) Deliver 25x Faster File Access in Go (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Memory maps in Unix allow a file to be mapped into virtual memory, enabling direct reads via pointers instead of slower seek/read operations. Benchmarks in Go show memory maps can be up to 25 times faster than using `ReaderAt` for random lookups and iterations. While writing to memory maps is inefficient due to page faults, they can still be great for read-heavy operations when files are cached.

<strong>The price of mandatory code reviews (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Based on data from 400+ companies and 3,000+ engineers, this article challenges the mandatory code review practice in software development. The research found that teams without code reviews are 1.9x more productive but produce 2.4x more bugs, while high-quality reviews (though 38% slower) reduce bugs by 61% compared to low-quality ones. Top-performing teams (90th percentile) achieve both speed and quality by being selective about when reviews are needed.

Apple's attention to detail, a hallmark of the brand, has declined in the last 8-10 years. This article points out inconsistent UI design across apps, intrusive permission requests, and the buggy, visually flawed "liquid glass" design as evidence of a decline in user experience.

<strong>Introducing PyTorch Monarch (17 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
PyTorch Monarch is a distributed programming framework that makes cluster programming easier by treating resources as local, similar to single-machine Python. Monarch organizes resources into meshes, enabling operations on entire clusters with fault handling and separation of control and data planes. It provides distributed tensors that integrate with PyTorch, allowing operations across thousands of GPUs.

<strong>Living dangerously with Claude (10 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Running coding agents like Claude with unrestricted permissions comes with increased productivity and the ability to outsource tasks, but also makes Claude vulnerable to prompt injection attacks. The safest thing to do is to sandbox coding agents, ideally on external systems with controlled network access, to mitigate these risks.

<strong>Programming With Less Than Nothing (9 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
An interviewer asks a candidate to solve FizzBuzz, and the candidate responds by attempting to implement the entire problem using combinatory logic in JavaScript. The interviewer is initially skeptical, recognizing the approach as an exercise in reinventing programming primitives from lambda calculus. The candidate then constructs numbers, lists, and string manipulation functions using combinators, eventually producing the desired FizzBuzz output.
