Airline pricing may seem mystifying, but behind every airfare is a complex system of fare buckets and inventory controls. Airlines don't just sell seats - they manage a dynamic inventory of fares, divided into booking classes (fare buckets) with different prices and rules. For the technically curious, understanding how fare buckets work reveals the "source code" of airline revenue management. This report delves into the hierarchy of booking classes, how airlines update seat availability across r
At Morphik, we build RAG tools to provide developers accurate search over complex documents. In this article, we explain why we operate over "images" of pages instead of doing OCR/ parsing. If you’ve ever tried to extract information from a complex PDF: one with charts, diagrams, and tables mixed with text, you know the pain. That invoice with a nested table showing quarterly breakdowns? The research paper whose intricate figures actually contain the key findings? The technical manual where the

I chat with Kostantsa Rangelova and Dave Jones, authors of a new Ember report, who find that solar-plus-storage costs have declined so much that it can now provide baseload-level power in sunny cities for less than the cost of new nuclear or even new gas. We discuss why even energy pros are behind the curve on this, how quickly the technology is improving, and why most of the world doesn't see natural gas as a viable option the way the US does.

There’s nothing worse than a test suite that fails randomly. Flaky end-to-end (E2E) tests erode confidence, slow down releases, and lead developers to ignore legitimate failures. If your team starts using the term “CI roulette,” it’s time to act. Flaky tests are fixable—but it takes visibility, discipline, and the right tooling. What Is a Flaky Test? A flaky test is one that fails sometimes and passes other times, without any changes to the code. They’re usually caused by: Timing issues (e.g
is a news editor with over a decade’s experience in journalism. He previously worked at Android Police and Tech Advisor. Google is introducing the option to easily switch between personal and work profiles in its Chrome browser on iOS, with data kept separate between the two. The new option is part of Google’s enterprise software package, and doesn’t allow non-enterprise users to switch freely between two Google accounts in the browser. Companies that adopt Chrome Enterprise can let employees
We don’t talk enough about the amount of paperwork we come across every day. From essential bank documents, work contracts, tax notices, and bills to invoices, application forms, IDs, letters, and more, keeping everything organized can be a chore. And even more so if there’s a mix of physical and digital paperwork to deal with. Scanning your documents and organizing them digitally is a smart idea. But while there are plenty of scanner apps, any features you might need beyond basic scanning are
Jacob O'Bryant | 19 Jul 2025 I've previously written about my latest approach to unit tests: [Y]ou define only the input data for your function, and then the expected return value is generated by calling your function. The expected value is saved to an EDN file and checked into source, at which point you ensure the expected value is, in fact, what you expect. Then going forward, the unit test simply checks that what the function returns still matches what’s in the EDN file. If it’s supposed to
Previously, we explored how memory is measured and what tools are available for inspecting usage in iOS apps. Now, let’s shift our focus to reducing memory consumption using a set of practical techniques and development best practices. But first let’s discuss different approaches to treat this problem. Initial Source of a Problem Every spike in memory has a cause, and memory optimization is no exception. Sometimes it’s a 3rd-party library — Lottie is a classic example, especially if you export
Announcing SecretSpec: Declarative Secrets Management We've supported .env integration for managing secrets, but it has several issues: Apps are disconnected from their secrets - applications lack a clear contract about which secrets they need - applications lack a clear contract about which secrets they need Parsing .env is unclear - comments, multiline values, and special characters all have ambiguous behavior across different parsers - comments, multiline values, and special characters al

Following the Big Bang, our universe expanded at an exponential rate. According to this theory, known as cosmic inflation, the explosive growth produced tiny quantum fluctuations that later evolved into galaxies. Cosmic inflation neatly explains how our universe got so large and mostly homogenous, and that’s why it’s remained a strong theory in cosmology for decades. But it’s far from perfect. Cosmic inflation depends on certain theoretical assumptions that can get rather arbitrary—not ideal fo
Alaska Airlines paused its operations for several hours, late on July 20. This was due to what the company called, "a significant IT outage" affecting its operations. About 3 hours later, flights resumed and the company posted on X: "Alaska Airlines has resolved its earlier IT outage and has resumed operations. We sincerely apologize for the inconvenience, and encourage guests to check your flight status before heading to the airport." The delays affected Alaska Air and Horizon Air flights at
hiding messages in playing cards I was recently thinking about the huge number of ways you can shuffle a deck of 52 cards and wondered if it would be possible to store arbitrary data, which I explore in this blog post. This blog post will go into the detail of how I found a way to store text inside the order of a deck of cards. If you want to play around with the tool, go here. How many different ways can we shuffle a deck of 52 cards? We can think of it like picking one card from 52, then one
With summer now well and truly here, you're probably spending more time in your backyard or garden than you would through the rest of the year. The warmer weather also means that new plants and flowers are blooming, and all of that extra color is always welcome, right? But did you know that some plants aren't as safe as they might look? In fact, you might be surprised just how many common plants and flowers could be dangerous to you, your family and even your pets. In this article, we enlist the
Interest will restart for SAVE borrowers whose loans remain in a general forbearance on Aug. 1. Viva Tung/CNET If you're a student loan borrower enrolled in SAVE, do you have to switch to a new repayment before interest payments restart in August? That's the question on millions of borrowers' minds, but the answer depends on your forgiveness options and financial situation. "It's crucial for borrowers to act based on their own personal situation," said Elaine Rubin, a student loan policy exper
The new Superman movie continues to rule the box office after its second weekend, leading the pack with $57 million from US audiences, and this relaunch of the DC universe is only getting started. Superman stars Rachel Brosnahan as Lois Lane, Nicholas Hoult as Lex Luthor and David Corenswet as the Man of Steel. The movie isn't an origin story; it picks up when Superman is already well-known (and moments after he loses any fight-winning streak he previously had). I won't provide any more details
After launching 37 different products over the last few years, I’ve had one go viral and almost all the others struggle to get any traction at all. Like many indie makers, I used to think the best strategy was to just keep launching, make more bets, and hope one finally catches fire. But here’s what I’ve learned: Virality is rare and nearly impossible to predict Most of my launches that failed didn’t actually fail, they just grew much slower than I expected My current project, Refgrow, took

Users won’t need a special phone or plan to take advantage of the benefits fr
The Apple Sports app, which allows users to track sports scores in real-time, today expanded its coverage of soccer. With the new 3.1 update, fans of the FA Community Shield soccer tournament can now follow along inside Apple Sports. Also notable is that the app is now available to download in Mexico. This means fans of Liga MX can now use the app for the first time to track the performance of their local teams, as well as how they fare in the MLS Leagues Cup. Apple also said the app has incre
Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells in human tissues, and observe “animalcules” — bacteria and protists — in the water of a lake. Increasingly powerful light microscopes followed, revealing cell organelles like the nucleus and energy-producing mitochondria. But by 1873, scientists realized there was a limit to the level of detail. W
In the early 2010s, researchers in Mexico City noticed that sparrows and finches at the national university were lacing their nests with cigarette butts. The birds would collect the butts—mostly smoked—carefully remove the outer paper layer, and weave fibers from the filters into their homes, among the twigs and grass.

Annealed neodymium iron boron magnets sit in a barrel at a Neo Material Technologies Inc. factory in Tianjin, China on June 11, 2010. China's exports of rare-earth magnets to the United States in June surged more than seven times from the prior month, as American firms clamor to get hold of the critical elements following a preliminary Sino-U.S. trade deal. In April, Beijing placed restrictions on several critical magnets, used in advanced tech such as electric vehicles, wind turbines and MRI
We did not visit Poland often. Only when someone died. I have not been able to bring part of my mother’s ashes to Poland yet because of the pandemic. They sit in my living room, waiting to join my other dead relatives in her village of Bedoń. I live in California, 3,000 miles away from where I grew up, and when my mother couldn’t sleep she’d call me. I always picked up. “I think I know how I got sick,” she said once. My mother had an aversion to being sick and to anyone knowing about it. Her
Published on July 09, 2025 Ever wondered how cartoons create that hand-drawn “jitter” effect? I recently watched an ARTE documentary about Neapolitan pizza and was fascinated by the animated illustrations (drawn in simple shapes and plain colors) that accompanied the segment where the recipe and its ingredients were presented. The illustrations were static, but they had a subtle animation effect that made them look like they were moving slightly. See for example in this short clip, where you c
Log by Time, not by Count July 20, 2025 "How to Log" is a surprisingly deep topic in software engineering with many different viewpoints, and they're almost all valid in different situations. I'm going to argue that when processing lots of events, it's best to log every X seconds, rather than every X messages. This is a simple concept, but I've never seen it written down before. Let's quickly look at some pseudocode to understand what I mean. Count-based logging num_events_processed = 0 whi
At WWDC25, Apple introduced a few new capabilities to the Photos app for iOS 26. Most notably, it reintroduces a tab bar layout after last year’s controversial single-page redesign. It also allows you to create spatial scenes from existing photos. On top of those headlining features, there’s another underlying feature in the Photos app for iOS 26 that a lot of users might appreciate, and thats event details. Let’s explain. With iOS 26, if you’ve gone to a concert, sporting event, or some sort
Java Criminally Underhyped? Not Back in 1997. Earlier today, a fun little moment of Twitter serendipity alerted me to an article by Jackson Roberts, a computer science student at the University of Colorado, entitled “Java is criminally underhyped”. It’s a really interesting article, and Jackson’s observations correlate with a lot of my own thinking about languages and platforms, although I am squarely in the .NET / CLR camp on that particular front. But Jackson ends his article: I am curious
