Do you really need an OpenTelemetry Collector? If you're just sprinkling SDKs into a side project - maybe not. If you're running a multi-service production environment and care about cost, performance, security boundaries, or intelligent processing - yes, you almost certainly do.

DACLab says it can remove CO2 using less electricity than many competitors

techcrunch.com Tim De Chant 2025-09-20 08:00:00

The world’s countries may have pledged to cut its carbon pollution, but with global emissions reaching an all-time high last year they’ve fallen far short. Digging out of that hole is going to require removing carbon straight from the atmosphere. But it comes with a hefty price tag, mostly because of the energy required. Removing one metric ton of CO 2 using direct air capture is expected to require around 2,000 kWh of electricity when the technology is sorted and scaled up. One startup called

Traveling to Europe? You Need to Know About These New Identity Checks and Fees

Travelers to Europe will soon have their fingerprints and facial data captured and verified for entering and exiting EU countries, signaling the beginning of the end for passport stamping. The new system, which the EU is calling the EES (Entry/Exit System) will kick off on Oct. 12 and will be gradually phased in across checkpoints through April 9, 2026. By April 10 of next year, the EU hopes to do away with physical passport stamping in favor of a digital biometric system that it says will make

Frontier buys $31M worth of antacids for the ocean

Frontier, the carbon removal clearinghouse founded by Google, Strip, Shopify, and others, announced today that it is buying 115,208 metric tons of carbon removal credits from geoengineering startup Planetary in a deal worth $31.2 million. Where most Frontier deals to date have bought carbon from startups specializing in direct air capture, enhanced weathering, or bioenergy with carbon capture, the organization’s agreement with Planetary is its first to do so by enhancing ocean alkalinity.

Google is expanding a key anti-theft feature to make your apps more secure

Hadlee Simons / Android Authority TL;DR Android’s Identity Check feature is being expanded in the upcoming Android 16 QPR2 update to better protect your sensitive apps. The feature will now enforce biometric-only authentication for any app that uses the biometric prompt, removing the screen lock credential as a fallback. This optional security measure will prevent thieves who know your PIN from accessing sensitive apps when you’re outside of a trusted location. Late last year, Google announc

Once upon a time, in their startling report titled "Bigger Monsters, Weaker Chains," ACLU analysts Jay Stanley and Barry Steinhardt argued that the US was quickly becoming a full-blown "surveillance society," where advanced technology and crumbling regulation come together to create the kind of world that was previously the domain of dystopian science fiction. "The fact is, there are no longer any technical barriers to the Big Brother regime portrayed by George Orwell," they wrote. That was in

Microsoft is buying tons of carbon removal from Xprize startup Vaulted Deep

techcrunch.com Tim De Chant 2026-01-11 02:03:19

Microsoft is building data centers as fast as it can, and that’s killing its carbon balance sheet. Since 2020, its carbon emissions have grown by nearly a quarter, undermining the pledge it made that year to remove more carbon from the atmosphere than it generates by 2030. So Microsoft has been buying massive amounts of carbon-removal credits to attempt to remedy that situation, including a newly announced purchase of 4.9 million metric tons from Vaulted Deep. Neither party disclosed the financ

CFOs want AI that pays: real metrics, not marketing demos

This article is part of VentureBeat’s special issue, “The Real Cost of AI: Performance, Efficiency and ROI at Scale.” Read more from this special issue. Recent surveys and VentureBeat’s conversations with CFOs suggest the honeymoon phase of AI is rapidly drawing to a close. While 2024 was dominated by pilot programs and proof-of-concept demonstrations, in mid-2025, the pressure for measurable results is intensifying, even as CFO interest in AI remains high.

OpenTelemetry for Go: Measuring overhead costs

news.ycombinator.com Nikolay Sivko 2026-03-14 05:09:17

Everything comes at a cost — and observability is no exception. When we add metrics, logging, or distributed tracing to our applications, it helps us understand what’s going on with performance and key UX metrics like success rate and latency. But what’s the cost? I’m not talking about the price of observability tools here, I mean the instrumentation overhead. If an application logs or traces everything it does, that’s bound to slow it down or at least increase resource consumption. Of course,

In the fast-paced world of CI/CD, understanding the performance and behaviour of your pipelines is crucial. GitHub Actions has become a popular choice for automating builds and deployments, but anyone who's debugged a flaky workflow or long-running job knows how challenging it can be to get visibility into what's happening under the hood. We usually rely on build logs, timing data, or guesswork when something goes wrong. Wouldn't it be nice to trace a pipeline run step-by-step, or have metrics o

Shaping Light – Volumetric Lighting

As I became more familiar with post-processing over the past few months, I was curious to push those newly learned techniques beyond pure stylization to achieve something more functional. I wanted to find new ways to enrich my 3D work which wouldn't be possible without leveraging effects and passes alongside custom shaders. As it turns out, post-processing is great entrypoint to enhance a 3D scene with atmospheric and lighting effects, allowing for more realistic and dramatic visuals. Because t

Our scene representation is a hybrid of primitive and volumetric model. (a) Primitive component. We explicitly allocate voxels primitives to cover different scene level-of-details under an Octree layout. Note that we do not replicate a traditional Octree data structure with parent-child pointers or linear Octree. We only keep voxels at the Octree leaf nodes without any ancestor nodes.
