A tale of Phobos – How we almost cracked a ransomware using CUDA
For the past two years we've been tinkering with a proof-of-concept decryptor for the Phobos family ransomware. It works, but is impractical to use for reasons we'll explain here. Consequently, we've been unable to use it to help a real-world victim so far. We've decided to publish our findings and tools, in hope that…

Don't link to line numbers in GitHub
Today I saw a co-worker take a link from a specific line number in our team’s github repository and place it in the comments section of a user story. This is very helpful for those who need to see a quick reference to the code that could be causing a defect, but it’s wrong . Here’s what you need to do instead.

Convolutions, Fast Fourier Transform and polynomials (2022)
You may remember from high school what a polynomial is. If so, you may also remember how to multiply two of them. But what if I told you that the method you were taught is slow as F? In this post we will connect polynomials with the Fourier Transform and convolutions, and show you how to multiply polynomials with…

Possibly all the ways to get loop-finding in graphs wrong
In my puzzle collection , there are many games in which you have to connect points together by edges, making a graph, and the puzzle rules say you must avoid making any loop in the graph. Examples are Net , Slant , and some configurations of Bridges (although not the default one). Loopy and Pearl also care about…

Practical Guide to SQL Transaction Isolation
You may have seen isolation levels in the documentation for your database, felt mildly uneasy, and went on with life. Few day-to-day examples of using transactions really mention isolation. Most use the database’s default isolation level and hope for the best. It’s a fundamental topic to understand however and you’ll…

Lessons Learned Reproducing a Deep Reinforcement Learning Paper
There are a lot of neat things going on in deep reinforcement learning. One of the coolest things from last year was OpenAI and DeepMind’s work on training an agent using feedback from a human rather than a classical reward signal. There’s a great blog post about it at Learning from Human Preferences , and the…

Designing a Tree Diff Algorithm Using Dynamic Programming and A*
During my internship at Jane Street 1 , one of my projects was a config editing tool that at first sounded straightforward but culminated in me designing a custom tree diffing algorithm using dynamic programming, relentlessly optimizing it and then transforming it into an A* accelerated path finding algorithm. This…

Ruby and Its Neighbors: Smalltalk
Smalltalk was the second major influence on Ruby's design. A different kind of influence, since almost nothing of Smalltalk's syntax made into Ruby. But many of the details of how objects work are directly inspired by Smalltalk, including the idea that every piece of data is part of the object system.

Apple Slaps Developers In The Face
[Adobe would like me to make it clear that the opinions below are not the official views of the company and are entirely my own.] By now you have surely heard about the new iPhone 4.0 SDK language that appears to make creating applications in any non-Apple-approved languages a violation of terms.
