The Flexible Job Shop Problem (FJSP) is a well-studied combinatorial optimization problem with extensive applications for manufacturing and production scheduling. It involves assigning jobs to various machines to optimize criteria, such as minimizing total completion time. Current learning-based methods in this domain often rely on localized feature extraction models, limiting their capacity to capture overarching dependencies spanning operations and machines. This paper introduces an innovative architecture that harnesses Mamba, a state-space model with linear computational complexity, to facilitate […]

Claude can code, but can it check binary executables? We already did our experiments with using NSA software to hack a classic Atari game. This time, we want to focus on a much more practical task — using AI agents for malware detection. We partnered with Michał “Redford” Kowalczyk,a reverse engineering expert from Dragon Sector, known for finding malicious code in Polish trains, to create a benchmark of finding backdoors in binary executables, without access to source code.

It’s also reasonable for people who entered technology in the last couple of decades because it was good job, or because they enjoyed coding to look at this moment with a real feeling of loss. That feeling of loss though can be hard to understand emotionally for people my age who entered tech because we were addicted to feeling of agency it gave us. The web was objectively awful as a technology, and genuinely amazing, and nobody got […]

Not everything that can be automated should be. As QA engineers and leads, we often face the same question: Should we automate this, or handle it manually? And the truth is – there’s no single answer. The right choice depends on context, stability, and value. Automation is powerful when it accelerates learning and confidence, not just when it replaces human effort. But manual testing is equally valuable when it provides context, empathy, and deep insights that automation can’t […]

Hello everyone, I’m currently working on training a Spiking Neural Network (SNN) to play Breakout using BindsNET and the OpenAI Gym environment. I want to extract and save the rendered frames from the Gym environment to visually compare the performance of different models I’ve trained. However, I’m struggling to figure out how to properly implement this frame extraction within the BindsNET pipeline. Has anyone successfully done this or have any advice/code snippets to share? Any guidance would be […]

When I first thought about this article, I had planned to go with a headline ‘Harness Matters’ or something cool like ‘A good harness is all you need’, but to my own shock, it seems to not actually make that much of an impact – atleast as far as MVP’ing a front end wireframe goes. Maybe much further down the line it might matter more than this and compounds on varying abilities present in each of them, but […]

Let me set the scene. You’ve shipped three .NET applications in the last two years. Each one has a DbContext, a generic repository, probably a Unit of Work wrapper. Maybe you even went full CQRS on the last one because you’d watched enough conference talks to feel guilty about not doing it. And every single time, you wrote the same scaffolding. Different entity names. Different connection string. Same bones. At some point you stop and think — why […]

Graph classification is dominated by permutation-invariant graph neural networks. We revisit this problem from a different perspective: can small language models (SLMs) act as graph classifiers when graphs are serialized as text? Unlike GNNs, sequence-based transformers do not encode permutation invariance by construction, raising a fundamental question about structural stability under node relabeling.We provide the first systematic study of permutation robustness in small graph-as-text models. We introduce an evaluation protocol based on Flip Rate and KL-to-Mean divergence to […]

Robust watermarking is critical for intellectual property protection, whereas existing methods face a severe vulnerability against regeneration-based AIGC attacks. We identify that existing methods fail because they entangle the watermark with high-frequency cover texture, which is susceptible to being rewritten during generative purification. To address this, we propose WaterVIB, a theoretically grounded framework that reformulates the encoder as an information sieve via the Variational Information Bottleneck. Instead of overfitting to fragile cover details, our approach forces the model […]
