w2vgrep is a command-line tool that performs semantic searches on text input using word embeddings. It's designed to find semantically similar matches to the query, going beyond simple string matching. Supports multiple languages. The experience is designed to be similar to grep.

SSHamble is a research tool for SSH implementations that includes:

• Interesting attacks against authentication
• Post-session authentication attacks
• Pre-authentication state transitions
• Authentication timing analysis
• Post-session enumeration

A command line journal inspired by https://github.com/jrnl-org/jrnl I wanted to have a minimal journaling system that would store my files encrypted, and be easy to setup across multiple devices without needing too many dependencies.

This article is about the neural conundrum behind the slowness of human behavior. The information throughput of a human being is about 10 bits/s. In comparison, our sensory systems gather data at bits/s. The stark contrast between these numbers remains unexplained and touches on fundamental aspects of brain function: what neural substrate sets this speed limit on the pace of our existence?

You’re likely reading this text in a browser. Press Ctrl+F (⌘+F on macOS) and search for the word "text" on this page. The browser will instantly show you how many times the word appears. Even in texts hundreds of times longer than this page, browsers can quickly find the desired substring. Today, we’ll look at the algorithms that make this possible.

I can’t get through a zoom call, a conference talk, or an afternoon scroll through LinkedIn without hearing about vectors. Do you feel like the term vector is everywhere this year? It is. Vector actually means several different things and it's confusing. Vector means AI data, GIS locations, digital graphics, and a type of query optimization, and more. The terms and uses are related, sure. They all stem from the same original concept. However their practical applications are quite different.

So “Vector” is my choice for this year’s name collision of the year.

Recently I realize I've accumulated quite a few packages and wanted to do some cleaning and organizing.

These are the ones I kept and find useful.

The game engine for high-performance cross-platform games.

Firefiles is an open-source alternative to Dropbox that lets you manage files across multiple cloud storage providers through a single interface.

The Story of Chaos Theory and Some Fun Facts About the Scientists.

People seem to think that writing a garbage collector is really hard, a deep magic understood by a few great sages and Hans Boehm (et al). Well it’s not. In fact, it’s rather straight forward. I claim that the hardest part in writing a GC is writing the memory allocator, which is as hard to write as it is to look up the malloc example in K&R.
