Edward J. Schwartz: Computer Science Researcher

In Part 1 and Part 2, I reported some peculiar behavior for quantized Qwen3.5-2B models.

This post contains a broken experiment in which thinking was inadvertently enabled but did not use sampling parameters intended for thinking…

In Part 1, I introduced auto-bench, a tool for benchmarking quantized LLMs for local coding agents, and shared some results from a…

OOAnalyzer is one of my favorite projects for a few reasons.

Like many people, when I'm on the go and need to do something, I reach for an LLM assistant.

New open LLMs are released constantly and keep improving.

I'm happy to announce that my student Luke Dramko's paper "Idioms: A Simple and Effective Framework for Turbo-Charging Local Neural…

(Apologies in advance, this is probably going to be rambling.)

My colleague Cory Cohen recently asked me to take a look at some surprising behavior in Ghidra's decompiler.

Systematic Testing of C++ Abstraction Recovery Systems by Iterative Compiler Model Refinement I'm excited to announce that our paper…

Many people seem to be unaware that decompilers have a decompilation export feature, which is particularly beneficial when you are trying to…

Can existing neural decompiler artifacts be used to run on a new example?

In Part 1, we showed that tool-calling agents built using open source LLMs and LangChain almost universally performed poorly.

Given the recent change in government here in the US, I've been thinking a lot about my personal beliefs and values.

For the past several years, I've been using Advent of Code as an excuse to do some professional development and learn new languages.

One of the most exciting possibilities of AI and LLMs are agents: tools that allow LLMs to interact with various tools in order to solve…

I recently signed up for BlueSky.

This page documents my experience with "pressure washing" my vinyl fence and siding.

At some point, I hope to create a Notes section on my website that will turn Markdown files into a list of notes.

Fostering My wife and I started fostering rescue dogs mostly by accident.

In my last post I talked about how I have been using Ansible for my new laptop configuration, and shared my configuration for notion.

Sometime while I was in graduate school, I started using the notion window manager.

I'm a serial car leaser.

I was playing around with ChatGPT and it came up with this gem: In the thrilling world of ones and zeros, where the mere thought of assembly…

I saw a quote in a recent ACM article that resonated with me: Security must be a business enabler, not a hinderer.

Imagine that you reverse engineered a piece of malware in pain-staking detail, only to find that the malware author created a slightly…

Hello, Merry Christmas and Happy Holidays!

I've been working on a blog post that has some interesting images in it.

I'm trying to document a few things that I do infrequently enough that I tend to forget how to do them, and need to rediscover the process…

Sometimes it is necessary to use a bleeding edge Linux kernel such as to debug hardware issues.

Some days I hate computers.

I've been feeling left behind by all the exciting news surrounding AI, so I've been quietly working on a project to get myself up to speed…

I've mentioned a few times that I'm an avid skier.

My family and I had quite the day attending the 2023 Central Pennsylvania Open Source Conference (CPOSC) yesterday at the Ware Center in…

Last December, I did most of Advent of Code in Rust, which I had never used before.

Right before the holidays, I, along with my co-authors of the journal article The Art, Science, and Engineering of Fuzzing: A Survey…

It's been an exciting year so far.

I'm happy to announce that a paper written with my colleagues, A Generic Technique for Automatically Finding Defense-Aware Code Reuse…

One of the aspects I like about my job as a researcher at SEI is that I split my time between being an academic researcher and a software…

I'm a long time user of weechat.

My colleagues and I wrote a survey paper on fuzzing entitled The Art, Science, and Engineering of Fuzzing: A Survey.

My colleagues and I finished the camera ready version of our DIRE paper on variable name recovery.

Variable Recovery As far back as I can remember, one of the accepted dogmas of reverse engineering is that when a program is compiled, some…

Many people don't know that in addition to my work with computers, I'm very passionate about exercise and fitness.
