Iterated Log Coding: A Novel Floating-Point Encoding Format

2025-02-26

This article introduces a novel real number encoding format—iterated log coding. Unlike traditional floating-point representations, this format uses a sequence of sign bits to represent numbers, each sign bit indicating the positivity or negativity of the number within a specific range. This approach allows for a remarkably wide range of representable numbers, including extremely large or small values that are beyond the capabilities of traditional floating-point formats. It features a unique lexicographic ordering property. While the precision distribution is non-uniform, the method offers advantages in representing numbers within certain ranges, particularly where extremely large or small values are involved and precision requirements are less stringent.

Mysterious Squares in Windows Filenames: A UTF-16 Surrogate Pair Adventure

2025-02-26

This article describes a curious phenomenon in Windows: many small executables with strange squares in their names appearing in Task Manager. These files are not malicious; the issue stems from the use of UTF-16 surrogate pairs in filenames. UTF-16, to accommodate extended Unicode characters, uses surrogate pairs to represent characters beyond the Basic Multilingual Plane. When string manipulation produces isolated or malformed surrogate pairs, filenames become unrenderable. The article explains surrogate pairs and provides a Python script to generate files with unrenderable filenames, reproducing the phenomenon.

Low-Overhead Statistical Memory Profiling in PyPy: Integrating VMProf and the GC

2025-02-25

This blog post describes a novel approach to low-overhead statistical memory profiling for PyPy. Instead of recording every allocation, it samples every nth allocated byte, cleverly integrating the sampling logic into PyPy's garbage collector's (GC) bump pointer allocator check. This ensures the fast path remains identical with and without memory sampling, minimizing overhead. Experiments demonstrate good performance across various sampling rates, offering finer control and lower overhead for memory profiling.

LLMs: The Unexpected Success of Document Ranking

2025-02-25

This paper argues that Large Language Models (LLMs) can be effectively used for listwise document ranking, and that surprisingly, some complex problems can be solved by transforming them into document ranking problems. The author demonstrates this by using patch diffing to locate N-day vulnerabilities. By reframing the problem as ranking diffs (documents) by their relevance to a security advisory (query), LLMs can efficiently pinpoint the specific function fixing a vulnerability. This technique has been validated at multiple security conferences and can be applied to other security problems such as fuzzing target selection and prioritization. Future improvements include analyzing ranked results and generating verifiable evidence, such as automatically generating testable proof-of-concept exploits.

Xcode's Constant Phone Home: Privacy Concerns and Build Speed Bottlenecks

2025-02-25

Developer Jeff Johnson discovered that Xcode frequently connects to Apple servers during project builds, leading to slow build times, especially during the "Gather provisioning inputs" phase. By disabling connections to developerservices2.apple.com using Little Snitch, he resolved the build speed issue. He also found that Xcode connects to other Apple servers, such as devimages-cdn.apple.com and appstoreconnect.apple.com, upon launch and project opening, seemingly unnecessarily and potentially transmitting developer information to Apple. Jeff argues that Xcode acts as a developer analytics collection mechanism, compromising developer privacy.

HTTP/2: Why It Doesn't Matter in Ruby HTTP Servers

2025-02-25

This post discusses the relevance of HTTP/2 support in Ruby HTTP servers like Puma. The author argues that while HTTP/2's main advantage – multiplexing for faster page load times – is significant over the internet, it offers little benefit on a LAN. Low latency and long-lived connections within a LAN minimize the impact of TCP slow start. Furthermore, HTTP/2's server push feature proved detrimental and has been superseded by the more elegant 103 Early Hints. The author advocates leaving HTTP/2 handling to load balancers or reverse proxies, simplifying deployment and maintenance for the application server.
