| 1. | HackerRank open sourced its ATS. My resume scored 90/100. Oh wait 74. No – 88(danunparsed.com) |
| 518 points by sambellll 10 hours ago | 206 comments | permalink | |
tl;dr: HackerRank's open-sourced ATS (hiring-agent) produces wildly inconsistent resume scores—the same resume scored anywhere from 66 to 99 across 100 runs, meaning a candidate could fail an 85-point cutoff 65% of the time purely by chance. The author traces this to flawed design: subjective categories like "projects" rely on LLM vibe-checks with no proper rubric, while "experience" gives everyone 25/25 regardless of seniority due to a two-line prompt. With 65% of the score weighted on open source and projects, the tool filters by noise rather than quality. | |

| 2. | GLM 5.2 beats Claude in our benchmarks(semgrep.dev) |
| 882 points by jms703 18 hours ago | 407 comments | permalink | |
tl;dr: Semgrep benchmarked open-weight and frontier models on IDOR vulnerability detection and found Zhipu AI's GLM 5.2 scored 39% F1 with just a bare prompt, beating Claude Code (32%) at roughly $0.17 per bug found. Both were beaten by Semgrep's own multimodal pipeline (53-61% F1), suggesting the harness/scaffolding matters more than the underlying model. The authors caution this is a single task on one dataset, but argue GLM 5.2's performance at ~1/6 the cost of frontier models—plus the ability to run locally—makes open weights newly viable for security teams. | |

| 3. | Age verification is just a precursor to automated attribution of speech(nonogra.ph) |
| 551 points by arkhiver 8 hours ago | 313 comments | permalink | |
tl;dr: Age verification laws, marketed as child protection measures, are actually identity attribution systems that link online accounts to real-world identities like SSNs and government IDs. This solves law enforcement's traditionally labor-intensive problem of identifying anonymous speakers, potentially enabling automated enforcement against inconvenient speech once adoption is widespread. The author urges readers to refuse verification, or if unavoidable, use third-party services paid in Monero. | |

| 4. | Historical memory prices 1960-2026(dam.stanford.edu) |
| 322 points by vga1 17 hours ago | 118 comments | permalink | |
tl;dr: An interactive dataset tracking historical memory prices ($/GB) from 1960 to 2026 across DRAM, NAND flash, and HBM, extending John C. McCallum's classic dataset with monthly updates from Keepa (Amazon retail) and quarterly HBM estimates from Epoch AI. It breaks out DRAM by generation (SDRAM through DDR5), HBM by generation (HBM2e through projected HBM4), and includes a modeled accelerator cost breakdown for Nvidia, AMD, Google TPU, and AWS Trainium. Raw CSV data is downloadable; caveats note that "cheapest retail" often reflects EOL clearance rather than leading-edge pricing. | |

| 447 points by engmarketer 19 hours ago | 584 comments | permalink | |
tl;dr: After an orthopedist diagnosed a Grade III partial-thickness subscapularis tendon tear and began aggressive treatment (including shockwave therapy and a homeopathic injection), the author ran their DICOM MRI files through Claude Code (Opus) for a second opinion, which instead found an intact tendon with only mild tendinosis. A follow-up arbitration run by Claude sided with the "no tear" reading at moderate-to-high confidence. The author acknowledges they can't fully trust either verdict but is now skeptical of the clinic's intervention-heavy plan. | |

| 504 points by bilsbie 23 hours ago | 403 comments | permalink | |
tl;dr: Congress is fast-tracking the KIDS Act, a bundle that combines a revised KOSA with bills like SAFE BOTS and SCREEN, imposing liability whenever platforms "knew or should have known" a user is a minor—effectively forcing age verification (via ID or facial scans) for all users despite disclaimers to the contrary. The package also pressures platforms to moderate broad categories of lawful speech (addiction, gambling, fraud discussions) and contains encryption carve-outs with loopholes that could undermine private and ephemeral messaging. | |

| 9. | Professor denounces mass AI fraud on an exam at Brown(english.elpais.com) |
| 421 points by geox 19 hours ago | 559 comments | permalink | |
tl;dr: Brown University economics professor Roberto Serrano caught at least 50 students cheating on a take-home midterm using ChatGPT, after the class averaged 96/100 but dropped to 48/100 on an in-person final—with 22 of 27 no-shows having previously scored perfect 100s. Serrano criticized Brown's administration for responding with silence and is abandoning take-home exams, while urging broader debate on AI-enabled academic fraud. The incident reflects a wider trend: Princeton recently ended its 133-year-old unproctored honor code system in response to AI cheating. | |

tl;dr: LibrePods reverse-engineers Apple's proprietary AirPods protocol to bring exclusive features—like noise control switching, ear detection, accurate battery status, conversational awareness, and head gestures—to Linux and Android. Spoofing a Vendor ID as Apple's unlocks additional capabilities such as accessibility settings and hearing aid customization, while features like Find My, spatial audio, heart rate monitoring, and high-quality two-way audio are planned but likely require root. The project is GPLv3-licensed and warns that librepods.org is an unofficial site falsely claiming affiliation. | |

tl;dr: A GitHub issue requests that OpenAI Codex add a `.codexignore` mechanism (both repo-level and global) to explicitly prevent the agent from reading or transmitting sensitive files like `.env`, `.pem`, or SSH keys to the model. The requester notes this was previously raised in issue #205, which was closed in favor of a Rust implementation (codex-rs), but no equivalent feature appears to exist there as of August 2025. | |

| 246 points by colinprince 23 hours ago | 97 comments | permalink | |
tl;dr: Medium users typing in Polish couldn't enter the letter Ś because the editor blocked Ctrl+S to prevent the browser's save dialog. The bug arose because Polish keyboards use Right Alt+S to type Ś, and Windows internally maps Right Alt to Ctrl+Alt—so the editor's Ctrl+S handler was swallowing the keystroke. The fix was a one-line change: only block Ctrl+S when Alt isn't also pressed. | |

tl;dr: Former MEP Patrick Breyer warns of a two-pronged EU push this weekend to revive "Chat Control" mass-scanning of private messages. EP President Metsola is reportedly trying to resurrect the expired Chat Control 1.0 regulation despite Parliament's March rejection, while Monday's trilogue on the permanent CSAR proposal could mandate warrantless scanning, "voluntary" detection as risk mitigation, and age verification that ends anonymous communication. Civil society has relaunched fightchatcontrol.eu to pressure lawmakers. | |

Violations could be reported to the Department of Labor and Economic Opportunity, potentially resulting in fines or overtime pay. The bill has been referred to the Labor Committee. | |

| 264 points by Brajeshwar 4 days ago | 173 comments | permalink | |
tl;dr: Princeton researchers are using reinforcement learning, inverse design, and diffusion models to automate RFIC design—a notoriously artisanal field where chips for 5G, radar, and satellite comms have traditionally been hand-crafted over years. Their AI-generated power amplifiers, which often look like QR codes rather than symmetric layouts, have achieved record bandwidth and efficiency while cutting design time from months to minutes. The main bottleneck now is training data, most of which sits locked behind corporate NDAs, prompting calls for open chip-design datasets akin to ImageNet. | |
