OpenAI Engineer Quits, Says Company Is Pure Chaos Inside

OpenAI CEO Sam Altman is setting a breakneck pace with his company, rolling out feature after feature to keep the multibillion-dollar gravy train steaming ahead. And that kind of drum beat, especially paired with ChatGPT's meteoric rise, is bound to cause plenty of chaos behind the scenes. In a blog post, former OpenAI engineer Calvin French-Owen, who helped build the company's new coding agent Codex, said there "wasn't any personal drama in my decision to leave" — but he did recap his experie

Adding lookbehinds to rust-lang/regex

In a previous blogpost, Erik wrote about how he implemented the linear time matching algorithm from [RegElk+PLDI24] in the popular regex engine RE2. In this one, we're looking at how to do the same thing for the official regex engine from the Rust language. Namely, we add support for unbounded captureless lookbehinds. First, let's discover the newly supported feature and its limitations. Lookbehinds allow regexes to make assertions about things preceding some part of the regex pattern without c

Building Modular Rails Applications: A Deep Dive into Rails Engines

I’ve been building Rails applications for the last 10 years on a daily base and almost all of them use active storage now. Users are uploading files and then the questions start rolling in from the team and they are always the same: “How much storage are we actually using?” “Can we see which files aren’t attached to anything anymore?” “What types of files are users uploading the most?” “Is there a way to browse through all our stored files?” I usually open the Rails console, write a few querie

Apple profits means iPhone users still get no real browser choice, says group

A web advocacy group says that iPhone users still get no real web browser choice more than a year after this was supposed to happen under antitrust legislation. The non-profit Open Web Advocacy (OWA) claims Apple deliberately places obstacles in the path of developers, and that’s because doing so protects a large slice of its profits … In theory, Apple allows choice Since the first iPhone, Apple retained exclusive control over web browsing on the device. Even when third-party browsers were al

Where are the iPhone’s WebKit-less browsers?

It’s been 16 months since a DMA ruling allowed iOS developers like Google and Mozilla to use their own browser engines in the EU, so… where are they? According to the Open Web Advocacy (OWA) — a nonprofit group of software engineers that advocates for the open web — Apple continues to place technical and financial restrictions on WebKit-alternative iOS browser engines that effectively stifle competition. OWA says these barriers include insufficient testing tools outside of the US, hostile legal

Ford’s Recall Affects Almost Every Cool Car They Make, and There’s No Fix Yet

If you’ve recently bought one of Ford’s best-selling vehicles, like the wildly popular Bronco, the workhorse F-150, or the family-hauling Explorer, the company has some unsettling news for you. Ford is recalling a staggering 850,318 of its most iconic models worldwide, including 844,098 in the U.S. alone, from the 2021-2023 model years due to a defect that can cause the engine to suddenly stall while driving. But the real kicker in this massive safety recall isn’t just the danger of your engine

Context Engineering Guide

What is Context Engineering? A few years ago, many, even top AI researchers, claimed that prompt engineering would be dead by now. Obviously, they were very wrong, and in fact, prompt engineering is now even more important than ever. It is so important that it is now being rebranded as context engineering. Yes, another fancy term to describe the important process of tuning the instructions and relevant context that an LLM needs to perform its tasks effectively. Much has been written already

Preliminary report into Air India crash released

'Why did you cut off?' pilot heard in voice recording of cockpit One of the findings from the report outlines how a pilot could be heard asking the other pilot in a voice recording of the cockpit in the moments before the crash: why did you cut off? The report says that both engine fuel cut off switches were turned to "cut-off" with a time delay. Below is an excerpt of that finding from the preliminary report: "The aircraft achieved the maximum recorded airspeed of 180 Knots IAS at about 08:

Windows 11 now uses JScript9Legacy engine for improved security

Microsoft announced that it has replaced the default scripting engine JScript with the newer and more secure JScript9Legacy on Windows 11 version 24H2 and later. The decision is driven by security concerns, as JScript9Legacy is expected to offer better protection against web threats, such as cross-site scripting (XSS), and also improved performance. "To provide a more secure experience, beginning with Windows 11, version 24H2, JScript9Legacy is enabled by default to handle all scripting proces

Seven Engineers Suspended After $2.3M Bridge Includes 90-Degree Turn

Ever had to make a 90-degree turn on a bridge? No? That’s the problem. In India, seven engineers just got suspended for designing exactly that. A brand-new $2.3 million bridge in Bhopal, India, is going viral—not because it solved traffic, but because it bends at nearly a 90-degree angle. Now, seven engineers have been suspended, a retired official is facing investigation, and the construction firms behind the project have been blacklisted.

Marjorie Taylor Greene Is Going After ‘Chemtrails’ With New Bill to Ban Weather Modification

House Representative Marjorie Taylor Greene (R-GA) is the latest lawmaker to seemingly go after the fictional threat of chemtrails. Over the weekend, Greene stated she will soon introduce a federal bill aimed at banning substances from being injected into the atmosphere. Greene announced the proposed bill in an X post published Saturday. The legislation would reportedly bar chemicals from being released into the air for the “express purpose of altering weather, temperature, climate, or sunlight

Possible Google Pixel 10a back cover makes a very early (and very sketchy) appearance

Ryan Haines / Android Authority TL;DR An image of a “Google Pixel 10A engineering back cover” has emerged online. The back appears to be slightly different from the Pixel 9a. It’s only been a few months since the release of the Pixel 9a, but that’s not going to stop leakers from going after its successor. We’ve already heard a few rumors about the Pixel 10a, such as its codename. Now a new potential leak may give us a few more details about the next entry to Google’s mid-range line. On the C

Prompting LLMs is not engineering

Prompting LLMs is not engineering published in: With the proliferation of AI models and tools, there's a new industry-wide fascination with snake oil remedies called "prompt engineering". As of July 2025 the term is now "context engineering" or "context prompting" or "context manipulation". To put it succinctly, prompt engineering is nothing but an attempt to reverse-engineer a non-deterministic black box for which any of the parameters below are unknown: training set weights constraints o

Nano-engineered thermoelectrics enable scalable, compressor-free cooling

Researchers at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have developed a new, easily manufacturable solid-state thermoelectric refrigeration technology with nano-engineered materials that is twice as efficient as devices made with commercially available bulk thermoelectric materials.

NASA tested a new SLS booster that may never fly, and the end of it blew off

NASA's Space Launch System appears to have a finite shelf life. The Trump administration wants to cancel it after just three launches, while the preliminary text of a bill making its way through Congress would extend it to five flights. But chances are low the Space Launch System will making it to nine flights, and if it does, it's questionable if it would reach that point before 2040. The SLS rocket is a core piece of NASA's plan to return US astronauts to the Moon under the Artemis program, b
