10x The National Checking Average On Your Idle Cash
The average U.S. checking account pays ~0.07% APY. Most high-earning engineers leave their liquidity in low-yield legacy accounts. Optimize your finances with Wealthfront’s Cash Account: 3.30% APY + an extra 0.75% boost on your uninvested cash for Pointer readers when you open your first Cash Account (total 4.05% variable APY).
Zero monthly fees and instant transfers to eligible accounts. APY that is 10x the national average. Checking features built-in.
Learnings From Conducting ~1,000 Interviews At Amazon
— Steve Huynh, Gergely Orosz
tl;dr: “I’ve found the topic of behavioral interviews from a software engineer’s perspective somewhat under-discussed – even though this interview carries huge weight in securing an offer and what level you come in at. No matter how strong your technical skills are, especially at mid-sized and larger companies, you are unlikely to get an offer if you are deemed to not be a fit for what the company is looking for.”

Red-Teaming Your Strategy
— Mike Fisher
tl;dr: “The goal of red-teaming is not to slow decisions down indiscriminately. It’s to introduce just enough friction to prevent irreversible errors. What follows are practical mechanisms that create disconfirming evidence on purpose.”

Why Can’t They Just…?
— Lara Hogan
tl;dr: “The question ‘why can’t they just’ is valid, because it’s coming from a place of concern, about something that is either deeply affecting someone’s ability to get work done, or affecting their trust in senior leadership, or affecting their trust in the company. We shouldn’t avoid this question. So how do you face it head-on?”
Leadership Management
“The best way to predict the future is to invent it.” — Alan Kay
Threat Modeling Guide For Software Teams
— Gayathri Mohan, Jim Gumbley
tl;dr: “Rather than conducting security analysis as a separate or upfront activity, teams should integrate threat modeling into their development process through small, regular activities. The article helps teams get started and develop their practice using different approaches across application development, and infrastructure.”

The Search Engine Behind Cursor’s Agents
tl;dr: “turbopuffer is the search engine that Cursor’s agents use to index and retrieve over 1 trillion code files without blowing out margins. It’s built natively on object storage with smart caching, so it’s much cheaper than traditional RAG databases, but just as fast (p90 < 20ms). When Cursor switched to turbopuffer they cut their retrieval costs by 20x while improving agent reasoning.”

The Vertical Codebase
— Dominik Dorfmeister
tl;dr: “What we’d want is low coupling and high cohesion. A structure where it’s clear what our code interdependencies are and where modules are as focused as possible. Arguably, the horizontal split creates the opposite: No clear boundaries between modules and code living together that is only loosely related. We need an alternative.”
Architecture BestPractices
How The Heck Does Shazam Work?
— Shri Khalpada
tl;dr: “The trick is to transform the waveform into something more useful for a computer. Your phone runs a mathematical operation called a Fast Fourier Transform (FFT) on small slices of the waveform. Each slice gets decomposed from a single complex wave into a list of the individual frequencies present at that moment. You can think of it as asking: which pure tones would you need to add together to recreate this slice of sound?”
SystemDesign DeepDive
Agents With Taste
— Emil Kowalski
tl;dr: “An engineer has never been more leveraged than today thanks to a fleet of agents. But when it comes to more visual work, like animations, coding agents don’t quite know what great feels like. My way of getting there is to create a skill file for each aspect of the interface. If you know what great feels like, describe the rules, then give them to your agents so they can follow them.”
