Version 0.6.7 introduces significant enhancements to the language, particularly in the area of compile-time array manipulation. Key updates include: 1. **Mutable Compile-time Arrays**: Compile-time arrays can now be modified, allowing for direct assignment like `$arr[$i] = 123`. The only remaining immutable items at compile time are struct fields. 2. **Concatenation Operator**: The `+++` operator now functions on all array types, including those with gaps. 3.

The author discusses experimenting with an app that has various protections against reverse engineering, such as jailbreak detection and code obfuscation. They mention modifying apps, like TikTok, to alter functionality, which requires understanding how the app works internally. The app in question, which is more complex than a simple Widget app, offers an interesting mix of these protections. The author outlines the process of attaching a debugger to the app, ideally on a jailbroken phone, using tools like ssh and lldb. However,

The article by Danila Vershinin discusses the utility of the NGINX `try_files` directive, particularly for setting up SEO-friendly URLs and improving website performance. The directive routes requests for pretty URLs through a bootstrap file in PHP frameworks, allowing static files to be served directly by NGINX without involving PHP-FPM, which enhances performance. A typical configuration demonstrates this benefit, especially since it can make websites function effectively without needing to identify all static file locations. However, the author highlights

The author missed releasing a blog post in January due to life and work commitments but is now sharing insights on Kotlin's Result type regarding its effectiveness for error handling. They discuss a recent conversation comparing Kotlin's Result with arrow-kt's Either, expressing a preference for Either due to perceived design flaws in Result. Result is described as a class in Kotlin's standard library that encapsulates successful outcomes or failures without altering the control flow like exceptions do. The author illustrates its use with an example, noting that

On February 10, 2025, the author reflects on nearly four years since publishing an article about fast interpreters using tail calls and the musttail attribute. This technique, initially applied to Protocol Buffer parsers, has since gained traction, as evidenced by a new tail calling interpreter developed by Ken Jin as part of his Bachelor's thesis. This interpreter, which integrates the techniques from the author's article, has demonstrated a 9-15% performance improvement in Python and is slated for release in Python

The author discusses their aspirations to mount a radar system on a drone for synthetic aperture imaging, having previously tested homemade radars on the ground. They note the high costs associated with medium-sized drones capable of such tasks (around 1,000 EUR) and highlight a research paper that utilized a DJI S900 drone. The total system cost of £15,000 is deemed too expensive for the author. However, recent drops in prices for small FPV drones, which can lift significant payloads, have

A US government official claimed that there are individuals in the social security system receiving benefits with birth years recorded as "about 150 years old." Some attribute this to the Social Security Administration (SSA) using a 1875 epoch for dates in its systems, suggesting that unknown birth years are defaulting to this year. However, this claim is disputed for several reasons. In 2007, the SSA published data indicating they had removed individuals born before 1870 from their records due to their un

Researchers at the University of Surrey have published a study suggesting that time may not be fixed in a single direction, challenging the traditional view that it flows irreversibly from past to future. This possibility arises from the behavior of quantum systems interacting with their environment, known as 'open quantum systems.' The study explores why humans perceive time as moving in one direction and proposes that this perception may be linked to the way these quantum systems operate. By isolating the quantum system from its vast environment and assuming that energy
