Frontier AI has broken the open CTF format

The competitive format of Capture The Flag (CTF) has been fundamentally changed by the use of AI tools, making it pay-to-win and reducing the art of security to a prompt. The scoreboard no longer reflects human growth and the community is losing interest, with many top teams and players struggling to stay competitive in the current format.

SQL patterns I use to catch transaction fraud

Fraud detection in transaction data is mostly SQL-based, using patterns like rapid transactions, geographic impossibility, and amount anomalies to identify suspicious activity. By combining multiple patterns and scoring each transaction, analysts can catch more fraud and reduce false positives, but require human review and careful tuning of thresholds to avoid losing customers.

Gaining control of every projector and camera on campus

https://www.edna.land/blogs/posts/scanning/1.png
The user developed a program to brute force DNS subdomains on their college network, eventually optimizing it to 200 Mibps per 2 threads, but was limited by the DNS server's capacity and was asked to stop by IT after causing a campus-wide outage. The user then discovered a secret fourth option to scan IP addresses instead of subdomains and built a port scanner using AF_XDP, which led to ...

Additive Blending on the Nintendo 64

The original PlayStation supported additive blending, making effects like explosions look cooler. The N64's Reality Display Processor had a more flexible way to control blending, but it was complicated to use.

The main thing about P2P meth is that there's so much of it (2021)

https://dynomight.net/img/p2p-meth/meth4.jpg
New meth made from P2P may be chemically different from old meth, but evidence suggests it's mostly due to increased availability and purity, not contaminants. The rise in meth use and overdose deaths is likely linked to the increased availability and potency of the drug, rather than a change in its chemical composition.

How to Write to SSDs [pdf]

The paper proposes a set of out-of-place optimizations that reduce write amplification across both the DBMS and SSD layers, improving throughput by 1.65-2.24× and reducing flash writes per operation by 6.2-9.8×. The proposed optimizations include compression & page packing, grouping by deathtime, ZNS support, aligning DB and SSD GC units, NoWA pattern, and using FDP placement hints to ...

EMiX: Emulating Beyond Single-FPGA Limits

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
FPGA-level emulation is a key step in pre-silicon chip design validation. However, emulating large-scale multi-core systems increasingly exceed the hardware resource capacity of a single FPGA, limiting the feasibility of full-system emulation. To address this challenge, we introduce EMiX, a scalable multi-FPGA framework that enables distributed emulation of multi-core RISC-V architectures ...
