ANTHROPIC'S PAPER SMELLS LIKE BULLSHIT

Anthropic's recent report on a Chinese cyber espionage operation coordinated by Claude may have been falsified. There is a lack of verifiable information and technical details. The report claims that the AI autonomously executed a significant portion of the attack, but it fails to provide IoCs, TTPs, or evidence to support its claims.

AGI FANTASY IS A BLOCKER TO ACTUAL ENGINEERING

The pursuit of Artificial General Intelligence (AGI) is bad for actual engineering. The belief in AGI, particularly within companies like OpenAI, is being used to justify environmentally damaging and exploitative practices in the pursuit of limitless scaling. AGI's supposed high expected value relies on arbitrary and unfalsifiable estimations while ignoring tangible negative externalities.

SUPERCOOKIE

Supercookie is a method that uses favicons to create a persistent, unique identifier for website visitors, even in incognito mode and after clearing browsing data. It exploits how browsers cache favicons, allowing servers to track whether a browser has loaded specific favicons, creating a unique fingerprint. This tracking method affects major browsers and is difficult for users to clear.

COINBASE DATA BREACH TIMELINE DOESN'T ADD UP: I HAVE RECORDINGS & EMAILS PROVING ATTACKS STARTED MONTHS BEFORE THEIR 'DISCOVERY'

This article goes over the personal experience of a sophisticated phishing attack targeting a Coinbase user in January. The author reported the attack, which involved the scammer possessing detailed personal information, to Coinbase, but received no response to their crucial question of how the attacker obtained the data. Coinbase later disclosed a data breach in May, attributing it to bribed overseas customer support contractors, but the author's earlier experience suggests the breach was active months prior.

BEHIND THE COMPLAINTS: OUR INVESTIGATION INTO THE SUSPICIOUS PRESSURE ON ARCHIVE.TODAY

AdGuard DNS was contacted by the Web Abuse Association Defense (WAAD), which demanded that it block Archive.today for hosting illegal content, with implied threats of legal action under French law. AdGuard's investigation revealed WAAD to be a recently formed, opaque organization with suspicious activities, potentially impersonating individuals and making false reports. AdGuard has filed a complaint with the French police and is investigating the connection between WAAD and the real lawyer.

WHY DO WE NEED DITHERING?

Dithering was initially necessary to simulate more colors than available in early computing due to memory limitations. It involves using limited palettes and adding noise with neighboring colors to create gradients, tricking the eye into perceiving a smoother transition. Ordered dithering uses a threshold map, while error diffusion algorithms, like Floyd-Steinberg, distribute the error to neighboring pixels for a less patterned result.

THINK IN MATH. WRITE IN CODE

Programmers often prioritize programming language features over their primary purpose: instructing machines rather than expressing ideas, which is better suited for flexible mediums like mathematics. Devs should “think in math,” which means using logical models and deductions to understand problems before coding to create better solutions.

NEEDY PROGRAMS

There's a shift in software design where programs now demand more from users than they offer. Mandatory accounts, constant updates, intrusive notifications, and annoying onboarding processes are driven by the program's needs, not the user's. Programs that quietly serve their function without demanding attention or personal information are better.

THE WRITE LAST, READ FIRST RULE

TigerBeetle, a financial transactions database, uses a system of record and a system of reference (Postgres) to maintain consistency in the absence of transactions. The "Write Last, Read First" principle guarantees data integrity by writing to the system of record last and reading from it first. Idempotent operations are necessary, as the application uses a durable execution framework (Distributed Async Await) that guarantees eventual completion through checkpointing and resumption.
