Stop Asking 'Can I?', Start Saying 'I Will': A Bias for Action

2025-02-23

Instead of constantly seeking approval, take initiative and inform your boss of your plans with a deadline. This article uses the author's experience in small companies (<200 employees) to illustrate a 'proactive' strategy: for tasks within your scope, act first, give your boss veto power, and set a clear deadline. This increases efficiency and avoids delays caused by waiting for approvals. This method ensures progress while keeping the boss informed and allowing for feedback.

Booting 5000 Erlang VMs on a 192-Core Ampere One Server

Underjord, a consultancy specializing in Elixir and Nerves, successfully ran 5000 Erlang virtual machines on a 192-core Ampere One server. Each VM runs a Linux IoT device using the Nerves framework. This was achieved using a new bootloader, little_loader, streamlining ARM64 QEMU VM booting and leveraging KVM acceleration. Challenges included compilation issues and memory optimization, but these were overcome by adjusting BEAM VM allocators, Erlang release modes, and Linux kernel parameters. Over 5000 VMs were successfully run, opening new possibilities for testing and development of the Nerves framework and potentially integrating into future Nerves tooling.

Exbody2: High-Fidelity Whole-Body Motion Mimicry in Humanoid Robots

2024-12-18

Researchers have developed Exbody2, a generalized whole-body tracking framework enabling humanoid robots to perform expressive motions with human-like stability. Trained in simulation using Reinforcement Learning and then transferred to the real world, Exbody2 decouples keypoint tracking from velocity control. It leverages a privileged teacher policy to distill precise mimicry skills, achieving high-fidelity replication of dynamic movements such as running, crouching, and dancing. Experiments on two humanoid platforms demonstrate superior performance compared to state-of-the-art methods, providing practical guidelines for advanced whole-body control in humanoid robotics.

The AI Job Apocalypse is Here (and it's not what you think)

Duolingo's recent layoffs, framed as an "AI-first" strategy, expose a hidden truth: AI-driven job displacement is already widespread. Hundreds of writers and translators have been replaced by AI, a trend echoed across creative industries, journalism, and even government. This isn't a robot uprising, but a calculated move by corporations using AI to cut costs and consolidate power. The resulting job crisis is particularly acute for recent college graduates, with unemployment rates reaching historic highs. While the full economic impact remains unclear, the crisis reveals a deeper issue: the erosion of valuable jobs and the potential for AI to exacerbate existing inequalities. We're facing a critical juncture, needing to define what kind of work we value and how to protect it before the AI-driven job apocalypse consumes us.

TeaVM 0.11.0 Released: New WebAssembly Backend

2024-12-15

TeaVM 0.11.0 has been released, featuring a brand new WebAssembly backend. The old WebAssembly backend, while functional, lacked adoption due to insignificant performance gains and a poor developer experience. The new backend, leveraging the WebAssembly GC proposal, addresses these issues, improving interaction with browser JS APIs and reducing binary file size. While currently slightly less feature-rich than the JS backend, it already supports JSO (Java-to-JS interaction API), aiming for parity in the next release. This release also includes bug fixes in BitSet implementation and adds support for various JS APIs, such as file reading, touch events, the Popover API, and Navigator.sendBeacon.

Mozilla's Betrayal: Firefox Users Revolt Over Data Privacy Changes

Mozilla's recent update to Firefox's Terms of Use has ignited a firestorm of outrage among users. The update grants Mozilla broad permission to use user data, a stark contrast to previous promises to never sell user data—promises now scrubbed from the Firefox FAQ. While Mozilla claims the data will only be used as described in its Privacy Notice, concerns remain about the potential use of this data for AI development. The vague wording and the removal of previous guarantees have shaken user trust, leading some to migrate to alternative, Firefox-based open-source browsers. This incident highlights the growing importance of data privacy and the repercussions of companies contradicting their past assurances.

Server CPU Utilization: Don't Be Fooled by the Numbers!

Do you rely on server CPU utilization to assess server performance? This author ran a series of stress tests and discovered that CPU utilization isn't linearly correlated with actual work efficiency. Especially above 50% utilization, hyperthreading and Turbo Boost significantly skew the relationship, leading to much higher actual throughput than the reported utilization suggests. Instead of relying on CPU utilization, the author recommends benchmarking to measure actual work completed for a more accurate assessment of server performance.

Google has scored a significant victory in its ongoing antitrust battle with the Department of Justice. While the DOJ still seeks significant regulatory changes to Google's search and Android operations, it has dropped its demand for Google to divest from its AI investments. Instead, Google will now be required to notify the government of future AI acquisitions. This is a substantial win for Google, which argued that restricting its AI investments would harm US leadership in the field.

Groundbreaking Study: Myocardial Infarction May Be Infectious

A groundbreaking study from Finland and the UK reveals that myocardial infarction (heart attack) may be an infectious disease. Researchers discovered that bacterial biofilms within atherosclerotic plaques can be activated by viral infections or other triggers, leading to inflammation, plaque rupture, and ultimately, a heart attack. This challenges the conventional understanding of heart attack pathogenesis and opens doors for new treatments, diagnostics, and even vaccines. The study found bacterial DNA in plaques and developed antibodies confirming bacterial involvement. The findings offer novel diagnostic and therapeutic strategies and the potential for preventing heart attacks through vaccination.

California Orders Uber to Fingerprint Drivers for Teen Rides

The California Public Utilities Commission (CPUC) ruled that Uber must fingerprint drivers for its teen ride-hailing service, Uber for Teens, to continue operating in the state. This decision stems from safety concerns regarding unaccompanied minors. While Uber has historically resisted fingerprint-based background checks, the CPUC cited the importance of protecting children from potential sexual offenders. The ruling significantly impacts Uber's operations, while competitor HopSkipDrive, which already employs stricter safety measures including fingerprinting, supports the decision. The added cost of fingerprinting may lead to higher prices for Uber's teen ride service.

Massive Supply Chain Attack: Malware Delivered via Abandoned Amazon S3 Buckets

2025-02-12

Researchers registered roughly 150 abandoned Amazon S3 buckets for around $400, finding they contained software libraries still in use. These buckets received eight million requests in two months, highlighting a massive vulnerability. An attacker could easily inject malware into these libraries, spreading it widely through software updates – a SolarWinds-style attack on a much larger scale. The abandonment of these buckets leaves developers unable to automatically patch vulnerabilities, giving attackers control over updates and hindering vendor identification of affected software. This underscores the critical flaws in software supply chain security; fixing it will be both difficult and expensive.
