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.

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.

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 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 ...
Researchers analyzed the effects of mildew on magnetic tape sound quality using ATR-FTIR, SEM, and Praat. The study reveals mechanisms for preserving audio archives and provides a basis for improved preservation strategies.
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.
Quasicrystals are rare in nature, created by violent events like asteroid collisions or lightning strikes, and only three naturally occurring types have been found in a single Russian meteorite. These include icosahedrite, decagonite, and i-phase II, each with unique properties and compositions.
Researchers found a zero-click root exploit for the Google Pixel 10 using a Dolby UDC vulnerability. They also discovered a VPU driver vulnerability that allowed arbitrary kernel read-write, which was patched within 71 days.
A group of about 30 runestones in scandinavia which refer to voyages to england. they are comparable in number only to the approximately 30 greece rune stones ' and the 26 ingvar runstone - which mentions an expedition to caspian sea region. orsteinn had this stone raised in memory of himself and his son hefnir. it is classified as being carved in the 'rune
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 ...
The author bought a cheap PSP from Japan through Buyee, a forwarding service, and ended up with a working console already modded with custom firmware. They also purchased a replacement battery and a new battery bay cover to complete the device.
The article discusses the "all exponentials eventually become sigmoids" talking point, where a trend may initially grow exponentially but eventually flatten out due to physical or practical limits. However, the timing of this transition is often uncertain and can be misidentified, leading to incorrect predictions.
A California bill requiring game publishers to offer refunds or updated versions of games after support ends has passed committee, a win for the Stop Killing Games movement. The bill, Protect Our Games Act, aims to ensure long-term playable access to online games, but faces hurdles in the full California Assembly and Senate.
Orthrus is a dual-architecture framework that unifies autoregressive LLMs with diffusion models for high-speed parallel token generation. It achieves significant inference acceleration, lossless generation, and zero redundant memory overhead.
The Cerelog ESP-EEG offers cleaner signals due to true closed-loop active bias at a lower price point than the OpenBCI Cyton. It uses an ESP32 instead of the Cyton's PIC32 and RFduino stack for high-bandwidth WiFi streaming.

Epiq uses Git for collaboration, tracking changes as events and allowing deterministic replay. It provides a local interface for issue management and syncing with Git repositories.
Erlang/OTP 29 introduces new features and improvements, including support for unsafe functions and improved security. It also includes experimental native records and new guard BIFs, as well as several compiler warnings and security enhancements.
A scientific calculator project uses an FPGA with a custom CPU and microcode firmware. It requires Verilator, installed with prerequisites and built in WSL2 on a Windows partition.
Claude uses World Labs and FAL to create 3D environments, SFX, and meshes from a single image in under 5 minutes. The process involves inputting an image, specifying edit preferences, and selecting a model type, then confirming each step.
The Zulip open-source project is transitioning to a nonprofit foundation, with Kandra Labs donating the company and its leadership team joining Anthropic. This change provides stability, charitable fundraising opportunities, and a renewed commitment to Zulip's values.

The user saved a collection of 13,000 manuals from being discarded and digitized them, making them available on the Internet Archive after an 11-year effort. The user has moved to a new industrial space to continue their work, which is supported by donations and a Patreon, and is grateful for the opportunity to have a dedicated space for their archiving and digitizing work.
The US DOJ is seeking personal data on hundreds of thousands of drivers who used the EZ Lynk Auto Agent app, accused of violating the Clean Air Act by allowing emissions control bypass. The move raises concerns over digital privacy and could set a precedent for regulatory enforcement cases.
