Good system design

I see a lot of bad system design advice. One classic is the LinkedIn-optimized “bet you never heard of queues” style of post, presumably aimed at people who are new to the industry. Another is the Twitter-optimized “you’re a terrible engineer if you ever store booleans in a database” clever trick. Even good system design advice can be kind of bad. I love Designing Data-Intensive Applications, but I don’t think it’s particularly useful for most system design problems engineers will run into. Wha

This researcher turned OpenAI’s open weights model gpt-oss-20b into a non-reasoning ‘base’ model with less alignment, more freedom

Apple TV+ among ‘final contenders’ for MLB Sunday Night Baseball, playoff games

Apple TV+ currently offers baseball fans Friday night games, but it sounds like Apple may soon be able to up its MLB offerings for subscribers. The Athletic says MLB rights are down to either Apple or Peacock Andrew Marchand writes at The Athletic: Apple and NBC/Peacock appear to be the final contenders for the “Sunday Night Baseball” package and, presumably, [first-round] playoff games. Apple already pays $85 million annually for exclusive Friday doubleheaders. It is possible MLB could split

REI Co-op Base Camp 6 Review: All-Weather, All-Season Family Tent

When my wife and I had kids, one of the first things we did was get a bigger tent. Fifteen years ago, the nicest car camping tent I could find was REI's Kingdom 6. All these years later, that tent is still going strong (a friend is off camping in it right now), but it turned out that we never really needed all that room. I'd happily trade that room for little more strength in stormy weather, which always seem to find me when I'm camping, and a smaller footprint that will fit in more spots. That

Why We Migrated from Neon to PlanetScale

In May 2025, during the same week Neon announced their acquisition, our databases went down four times. For hours. Database spin-ups, their entire value proposition, were completely disabled. Our "serverless" databases couldn't even start. That was the final straw in our decision to migrate to PlanetScale. Who We Are and Why Databases Matter More At OpenSecret, we're building something unique: a confidential computing platform powered by AWS Nitro Enclaves. Our flagship application, Maple AI,

7 Best Tents (2025), Tested: Camping, Family, and Outdoor Palaces

REI’s Base Camp tent is the best-designed, best-built six-person tent I've ever used. It also proved itself one of the most waterproof large tents in our testing. It's a traditional dome tent design, with two crossed poles and two side poles. The tent floor is high-quality 150-denier (150D) polyester, while the sides are a combination of mesh and 40D nylon. There's loads of storage pockets, double doors, great vents, and huge windows, making it comfortable even in summer heat. It's also one of t

I've tested every iPad sold by Apple right now - here's the model I recommend most

ZDNET's key takeaways The 11th-generation iPad 11th Generation normally retails for $349. The upgraded iPad has double the base storage as the previous generation, more RAM, and an upgraded processor in the A16 Bionic chip. However, it still isn't compatible with Apple Intelligence and doesn't support the Apple Pencil Pro. $299 at Amazon $349 at Apple $299 at Best Buy more buying choices It's not every day that a tech giant offers a new, improved product for an equal or lesser price than its

Virtual 6NF

One of the goals of this substack is to research ways of removing historical cruft from the way relational model is taught. One thing that puzzles me particularly is why Sixth Normal Form (6NF) is historically treated so... reverently? Lots of texts on the internet consider 6NF to be “exotic”, “academic”, “never used in practice”, etc., etc. As software developers, we can solve any problem by adding one level of abstraction, and database modeling is not an exception. I’m going to show that any

SpaceX is building a water pipeline to Starbase — but access comes with some conditions

The newest piece of infrastructure coming to Starbase, Texas, isn’t a launch mount or a booster. It’s a water pipeline, and who can hook up a tap (and on what terms) will shape the definition of “company town.” The new line, which will stretch from Brownsville to the newly incorporated city of Starbase, will replace the truck-hauled deliveries SpaceX has used to transport potable water for its employees and on-site residents. Brownsville Public Utilities Board (BPUB) COO Mark Dombroski confirme

President Trump says Intel’s new CEO “must resign immediately”

Donald Trump has called for the newly appointed chief executive of Intel, Lip-Bu Tan, to resign, alleging that the semiconductor industry veteran is “highly conflicted.” “The CEO of INTEL is highly CONFLICTED and must resign, immediately,” Trump said in his post on his Truth Social website on Thursday. “There is no other solution to this problem.” The US president’s post did not provide details of Tan’s alleged conflicts of interest. Trump’s broadside follows a letter from Republican Senator T

RFK Jr. defends $500M cut for mRNA vaccines with pseudoscience gobbledygook

If anyone needed a reminder that US health secretary and fervent anti-vaccine advocate Robert F. Kennedy Jr. has no background in science or medicine, look no further than the video he posted on social media Tuesday evening. In the two-and-a-half-minute clip, Kennedy announced that he is canceling nearly $500 million in funding for the development of mRNA-based vaccines against diseases that pose pandemic threats. The funding will be clawed back from 22 now-defunct contracts awarded through the

You can now try Microsoft’s Gaming Copilot AI assistant on PC

The beta version of Gaming Copilot is available to Xbox Insiders on PC via the Game Bar functionality. It's also available to try on Windows-based handheld gaming devices, but the company says the functionality there is currently limited. A variant of this tool recently launched as a beta for mobile .

Joe Keery and Liam Neeson Team Up for a Gross-Out Sci-Fi Film From the Writer of ‘Jurassic Park’

There aren’t many writers who you’d give top billing to over the cast, director, or intellectual property. But most writers aren’t David Koepp. Koepp may not be a household name, but his films are. He’s written the scripts for Jurassic Park, Mission: Impossible, Spider-Man, the last two Indiana Jones movies, Death Becomes Her, Panic Room, and more. He also directs (Premium Rush, Ghost Town, Stir of Echoes) and is a novelist too. He’s a pretty prolific guy and the primary author behind a brand ne

HHS Winds Down mRNA Vaccine Development Under BARDA

WASHINGTON, D.C. — The U.S. Department of Health and Human Services (HHS) today announced the beginning of a coordinated wind-down of its mRNA vaccine development activities under the Biomedical Advanced Research and Development Authority (BARDA), including the cancellation and de-scoping of various contracts and solicitations. The decision follows a comprehensive review of mRNA-related investments initiated during the COVID-19 public health emergency. “We reviewed the science, listened to the

Coinbase shares slide Tuesday as crypto play takes double-digit fall from July record

Shares were last down more than 5%. The decline occurred as investors adopted a risk-off stance on Tuesday and the three major averages declined. Coinbase is now off more than 30% from its all-time high of $444.65, reached on July 18.

Delta denies using AI to set personalized ticket prices

What just happened? Delta Air Lines has categorically denied using artificial intelligence to set ticket prices based on individual customer data, responding to concerns raised by several members of the US Senate. The airline issued its statement following criticism from lawmakers who alleged that Delta was exploring advanced pricing models designed to tailor fares to the maximum amount each customer might be willing to pay – a practice sometimes referred to as surveillance pricing.
