Electric trucks can draw on decades of gradual progress in the electrification of passenger cars, and take a giant leap forward in almost a single step: an improved charging standard (MCS) and #V2G technology!

Scania pioneers vehicle-to-grid through Megawatt Charging System for heavy transport
Scania has successfully demonstrated one of the world’s first vehicle-to-grid (V2G) implementations for heavy commercial vehicles using Megawatt Charging System

Zero days since I've discovered a random #CPython bug that triggers in very specific circumstances and I don't really have time to report it, nor can expect anyone to do it for me.
This time it's a test failure and refcounts being broken while running fastjsonschema's test suite on #Python 3.15 freethreading with pytest's --junit-xml option enabled 😱. And of course removing --junit-xml makes all tests pass.
EDIT: and of course I cannot reproduce outside Portage. Yet inside, it reliably crashes every single time.

This is the most detailed picture of a human cell ever made 🧪

Sam Bousaba on Instagram: "This is a single human cell. The white filament-like structures are microtubules, and the small colored particles are ribosomes. Your body contains on the order of ~37 trillion cells. Each cell functions like a highly organized, self-regulating factory operating continuously. There is no central “supervisor”—yet thousands of processes run in parallel with remarkable coordination. Every ribosome is constantly building proteins by linking amino acids together. In eukaryotic (human) cells, a ribosome typically adds about 5–10 amino acids per second (not ~20). Since a single cell can contain millions of ribosomes, protein production is massive—resulting in millions to tens of millions of peptide bonds formed per second per cell. The microtubules act as an internal transport network. Motor proteins such as kinesin move along these tracks, carrying cellular cargo. They “walk” step by step using ATP, at speeds of roughly 500–1000 nanometers per second. Each cell contains a dense network of these filaments, with many motor proteins moving simultaneously. Just beneath the cell membrane lies the actin cortex, a dynamic meshwork that helps maintain cell shape and resist mechanical stress. This structure is continuously remodeled—assembled and disassembled—allowing the cell to adapt to its environment. Now scale this up. Across ~37 trillion cells, each containing millions of ribosomes and hundreds to thousands of mitochondria, your body is constantly producing energy in the form of ATP. Total ATP turnover is enormous—roughly equivalent to your body weight in ATP recycled every day. The DNA in a single human cell, if stretched out, measures about 2 meters. Across all your cells, this would span distances comparable to traveling from Earth to the Sun and back many times (the exact multiple depends on assumptions about cell count and DNA packing). None of these processes are under conscious control. They began when you were a single cell and have continued uninterrupted ever since."

“If the same person keeps appearing in architecture debates, delivery risks, historical explanations, escalation paths, and cross-team translation, that is no longer just a compliment.
This is a system smell.”
I strongly resonate with this post!
There are bugs in our organization and processes that you can't discover in an IDE.

webkb: WebKB graphs (1998)
Web graphs crawled from four Computer Science departments in 1998, with each page manually classified into one of 7 categories: course, department, faculty, project, staff, student, or other. All graphs included in a single .zip; also included are 'co-citation' graphs, which links i and j if they both point to some k. Edge weights count the number of links from i to j.
This network has 349 nodes and 1393 edges.

I keep seeing the "cars replaced horses" thing related to "AI."
People keep comparing "AI" to cars (positively) without thinking about the fact that cars were forced on people (AAA bought up and destroyed tram lines, there were massive protests, etc), and are the primary driver of climate change that is currently on track to make complex human society impossible. Meanwhile, cities that weren't destroyed for cars, or that have reversed most of the damage, are some of the most desirable places to live.
Maybe we could take the car analogy as a warning. Maybe it could be a reminder to think about how forcing technology on people against their will can reshape society in a profoundly negative way.
The answer for cities has been to right-size transit. Eliminate cars wherever possible, maintain emergency vehicles and mobility aids, and find more efficient alternatives (bikes, trams, metros, and trains) where possible. I feel as though we can extrapolate from the metaphor.
We do not have to repeat the mistake of reshaping society around a single, oversimplified, solution in order to benefit a tiny minority. Perhaps we can actually choose the right technologies based on use cases, rather than hype or dogma.
Cars didn't replace horses. Cars replaced walkable cities, tram lines and mass transit, and children playing in the streets.
"Cars replaced horses" to the benefit of a small group of elite men, at tremendous cost to literally everyone else. When people say, "AI is the new 'cars replacing horses'" they are saying something very specific about their privilege and intentions.

AuthProbe: Specification-Driven, Multi-Identity Detection of Broken Object-Level Authorization in Recruitment API
Jay Barach
https://arxiv.org/abs/2607.20574 https://arxiv.org/pdf/2607.20574 https://arxiv.org/html/2607.20574
arXiv:2607.20574v1 Announce Type: new
Abstract: Broken Object-Level Authorization (BOLA), also known as Insecure Direct Object Reference (IDOR), has topped the OWASP API Security ranking since 2019 and is the root cause of some of the largest exposures of applicant data in recruitment technology. The defining feature of this flaw class is that a malicious request is byte-for-byte indistinguishable from a legitimate one, which is precisely why web application firewalls and single identity scanners fail to catch it. We present AuthProbe, an open-source, black-box scanner that detects BOLA and IDOR in HTTP APIs by driving its tests from an OpenAPI specification and by acting under two or more identities that the operator controls. AuthProbe discovers, for each identity, the objects that identity legitimately owns, then attempts to read one identity's objects while authenticated as another and confirms a leak by comparing the response against a ground-truth fetch by the true owner. It also walks predictable identifiers to expose enumeration and reports missing authentication and existence oracles. The tool returns a severity-thresholded exit code and machine-readable reports so that it can gate a continuous integration build. On a synthetic recruitment API in which the McHire failure class is reproduced, AuthProbe detects every planted cross-identity read with no false positives on a hardened counterpart, and its running time grows linearly with the number of objects under test. AuthProbe is released under the Apache 2.0 license with an authorized-use guardrail.

And yet another EV charging card giving access to ‘all’ chargers in Europe. And this one, too, makes ‘the pile of cards in your glove box’ redundant, just like the previous ones. And just like the next one, if this one adjusts its rates again.
