Building AI products in the probabilistic era

I was recently trying to convince a friend of mine that ChatGPT hasn't memorized every possible medical record, and that when she was passing her blood work results the model was doing pattern matching in ways that even OpenAI couldn't really foresee. She couldn't believe me, and I totally understand why. It's hard to accept that we invented a technology that we don't fully comprehend, and that exhibits behaviors that we didn't explicitly expect. Dismissal is a common reaction when witnessing A

Here’s a demo: https://www.youtube.com/watch?v=Mx8FyP7KvJg It’s surprisingly hard to find good product data. If you want your software to recommend products and deep-link to merchants, you’ll quickly discover that the data you need—clean titles, normalized attributes, deduped listings, current prices and

Why we still build with Ruby in 2025

When we started Lago, we picked Ruby on Rails for our core API. The choice was obvious because our founding team had decade of Rails experience. Rails was the fastest way we could build an API product. Today, we’ve receive millions of API calls a day. We’ve upgraded through multiple Ruby/Rails versions. Maybe that sounds silly in a world where young, Python/Go/JS-wielding entitlements have never even heard of Ruby. We do admit that we’ve added Go and Rust where it makes sense. But if we were

Ikea’s most Ikea product ever

Ikea is teaming up with a Swedish designer for its latest collection, and the first product being teased is a dedicated plate for Ikea’s greatest product: meatballs. The 12-piece Gustaf Westman collection that’s launching on September 9th includes a chunky blue serving dish that is shaped to fit exactly 11 of the delicious morsels “in a celebratory row.” “I love designing objects for a specific function – i

Vendors that treat single sign-on as a luxury feature

Why does this exist? Single sign-on (SSO) is a mechanism for outsourcing the authentication for your website (or other product) to a third party identity provider, such as Google, Okta, Entra ID (Azure AD), PingFederate, etc. In this context, SSO refers to a SaaS or similar vendor allowing a business client to manage user accounts via the client’s own identity provider, without having to rely on the vendor to provide strong authentication with audit logs, and with the ability to create and del

Branch prediction: Why CPUs can't wait?

Recently, I have had some free time and started learning some low-level computer fundamentals, trying to practice and better understand the concepts in greater detail. Along the way, I learned about a modern compiler infrastructure named LLVM, which is a target-independent optimizer and code generator that has been used as a part of many compilers for different programming languages like Rust, Zig, or Haskell. While diving into LLVM’s aggressive optimization features, I have a humbling realizati

The Plan to Turn the Caribbean’s Glut of Sargassum Into Biofuel

Esteban Amaro, director of the Quintana Roo Sargassum Monitoring Network, agrees that fuel is the best product to focus on. Processing the seaweed into other consumer products is possible, but inadvisable given that the health risks of doing so have not yet been sufficiently studied. “I believe that sargassum’s purpose is to produce energy, because when it decomposes, it releases many heavy metals such as arsenic, lead, and cadmium,” Amaro says. “Therefore it is better to produce biofuels or bi

Teaching the model: Designing LLM feedback loops that get smarter over time

Subscribe Now Large language models (LLMs) have dazzled with their ability to reason, generate and automate, but what separates a compelling demo from a lasting product isn’t just the model’s initial performance.

A treaty to end plastic pollution is still out of reach — that’s not necessarily a bad thing

is a senior science reporter covering energy and the environment with more than a decade of experience. She is also the host of Hell or High Water: When Disaster Hits Home , a podcast from Vox Media and Audible Originals. The nations of the world have been on the precipice of reaching a global agreement to curb plastic pollution for a few years now. Delegates from 184 governments met in Geneva this month to try to hammer out a final treaty, but in the end, they walked away without a deal. This

Philips Hue accidentally reveals major product lineup ahead of launch

TL;DR Philips Hue briefly put up a page revealing a range of new smart lighting products on its website before taking the page down. The Festavia line is getting expanded with the addition of two new models: Festavia permanent lights and Festavia globe string lights. The company is also releasing a gradient strip light and a light bulb that uses 40% less power. Mistakes happen, and sometimes those errors lead to leaks of products we can look forward to. It looks like that’s exactly what happe

Let's get real about the one-person billion dollar company

If you like this post, follow my journey on Twitter: https://x.com/random The biggest hurdle to the one-person billion dollar company is not AI capability, but founder pain tolerance. Sam Altman is betting on it in his private group chats. Dario Amodei predicted it'll happen in 2026. These geniuses think the one-person billion dollar company is inevitable, and unicorn teams are getting smaller, but a one person? That’s not going to just happen. One person is an intentional choice by an i

Reflecting on My Failure to Build a Billion-Dollar Company (2019)

Feb 7, 2019 by Sahil Lavingia Reflecting on My Failure to Build a Billion-Dollar Company In 2011, I left my job as the second employee at Pinterest — before I vested any of my stock — to work on what I thought would be my life's work. I thought Gumroad would become a billion-dollar company, with hundreds of employees. It would IPO, and I would work on it until I died. Something like that. Needless to say, that didn't happen. Now, it may look like I am in an enviable position, running a prof

Trump delays China tariff increases by another 90 days

President Donald Trump has signed an executive order extending lower tariffs with China for another 90 days, CNBC reports. The new executive order was signed before the previous agreement was set to end on August 12 at midnight. The extension will maintain the current 30 percent tariff on goods from China while representatives from both countries negotiate a new trade deal. The previous agreement lowered US tariffs down from 145 percent to 30 percent, and Chinese tariffs down from 145 percent t

Low-cost MacBook production starting soon, possible $599 or $699 pricing

We learned back in June that Apple is working on a new entry-level MacBook, to be powered by the A18 Pro chip rather than an M-series processor. This would be the first time the company has ever offered a MacBook below $999. A new supply-chain report says that the first stage of production is scheduled to begin sometime next month, with full-scale manufacturing potentially in progress by the end of the year … Low-cost MacBook The MacBook Air has always been the cheapest model offered by Apple

Sonos says it’s forced to raise prices while trying to win back customers

During what's supposed to be a year of redemption, Sonos has announced that its gadgets will become more expensive this year, complicating the company's comeback plans. Tariffs that US President Donald Trump announced last week take effect today, including a 19 percent tariff on goods imported from Malaysia (the levy is said not to apply to semiconductors and was cut down from a 25 percent tariff that Trump threatened in July.) Among other countries affected is Vietnam, which now sees a 20 perc

Let's stop pretending that managers and executives care about productivity

Let's stop pretending that managers and executives care about productivity I’ve just been on a bit of a summer break. Did a bit of travel locally. Visited Hvalfjörður. Walked a lot. I know from experience that if I don’t take a summer break, the winter becomes more of a slog and my thoughts become groggier. Often, as soon as you rest, your mind starts to “helpfully” come up with ideas to help fill your time. One of the invasive thoughts that kept prodding my brain during my break was about mo

A Sonos Price Hike Is About to Make a Bad Situation Even Worse

As a company, there are lots of things you can do when people are upset with your product. You could offer concessions (discounts in an effort to drive demand), swap your CEO (that’s a statement and a vibe shift), or you could pledge to do better and actually fix issues making people upset (imagine that!). One thing I would not recommend doing when times are tough, however, is raising prices, but Sonos seems to have been forced into this exact scenario. According to Sonos’ newish CEO, Tom Conra
