Folk CRM's co-founder Simo Lemhandez reveals the company's path to 5X year-on-year growth and 100,000 users. Folk's team created substantial early interest with a waitlist before building the product then spent 18 months developing a robust solution before beta testing. By manually onboarding early users, they gained valuable insights that informed their iterative pricing strategy, which involved doubling prices every 6 months.
This article delves into the cognitive biases that influence how people search and select information online. Confirmation bias leads users to favor content that aligns with their preconceptions, while authority bias makes them trust content from perceived experts. Tactics for marketers include using power words to establish trust, conducting thorough keyword research to match user intent, and enhancing content with authoritative signals such as certifications and expert endorsements.

The simplified React utilizes Fiber architecture and concurrency mode to avoid blocking the main thread during rendering. It is able to execute tasks during browser idle time. It uses a linked list structure to connect work units and triggers updates through a custom useState implementation.
Facebook used Memcached, a key-value store, to efficiently handle billions of requests per second. It achieved this by scaling Memcached at three levels: cluster, region, and worldwide. It used parallel requests and batching, optimized client-server communication, and managed congestion effectively to reduce latency. “Memcache pools” were used to reduce load on their databases.
This developer discovered a significant performance issue in a database query used for indexing posts in their application Mattermost. The query was initially slow due to too much filtering, but was sped up by using PostgreSQL's row constructor comparisons. To help find this speed boost, the developer used the BUFFERS option in EXPLAIN statements for detailed insights and prioritized Index Cond over Filter for efficient queries.
Microservices are popular and great for scalability and team organization, but can bring problems to smaller organizations. Too many services can be hard to maintain, create excessive interdependencies, and make downsizing difficult in tough economic times.
Traditional code reviews, which focus on manually finding errors, have become a bottleneck for engineering teams. With advancements in automated testing and static code analyzers, code reviews can now shift their focus from error-finding to knowledge sharing and long-term codebase health.
This developer added a quicksort animation feature to a game to visually sort items while handling potential changes in the list being sorted. Instead of optimizing the quicksort algorithm to resume from its last state, the developer chose a simpler, inefficient solution (on purpose): the sorting illusion is created by repeatedly running the algorithm from the start until a change occurs.
Server-sent events is a protocol that allows web servers to push data to clients without the need for alternative mechanisms such as pinging, long-polling, or WebSockets. Better SSE is a dependency-less server-sent events implementation for Node, written in TypeScript.

Billions of Google users will soon see AI-generated summaries at the top of many of their search results. The AI Overviews are designed to take out the hard work of searching so users can focus on the important things. Google announced several other AI-powered features at its I/O developer conference, such as a feature in Lens that lets users search by capturing a video, a planning tool that can generate trip itineraries and meal plans with a single query, and suggestions within search results. While similar products have come under scrutiny for summarizing content and not directing users to the actual sources of information, Google says that early data shows that the new way of searching will actually lead to more clicks to the open web.
Ilya Sutskever, OpenAI's co-founder and chief scientist, is officially leaving the company. Sutskever helped lead the coup against Sam Altman and then later changed his mind. His employment status had been ambiguous since the ouster. Jakub Pachocki, the company's director of research, will be OpenAI's new chief scientist.
A large long-term trial of semaglutide found that early weight loss from the drug is generally maintained for up to four years, with the participants in the study receiving weekly injections. The participants in the study tended to lose weight over the first 65 weeks on the drug but then hit a plateau. Semaglutide reduced participants' risk of heart attack, stroke, and cardiovascular-related deaths by 20% over the span of a little over three years. 52.4% of participants who received the drug in the study moved to a lower category of body mass index during the trial.
A protein-based gel developed by researchers at ETH Zurich can break down alcohol in the gastrointestinal tract without harming the body. The gel, made from whey protein fibrils, uses individual iron atoms to convert alcohol in the intestine into harmless acetic acid. It has been shown to reduce blood alcohol levels in mice by up to 50%. The gel is only effective as long as there is still alcohol in the gastrointestinal tract, so it can't help with alcohol poisoning. While it has yet to be tested in humans, the researchers are confident it will be a success, so they have already applied to patent the gel.

Project IDX is an AI-centric, browser-based development environment that was launched as an invite-only service in August. Over 100,000 developers have already tried the service, which is now available in open beta. Google has added an integration with the Google Maps Platform into the IDE and integrations with the Chrome Dev Tools and Lighthouse to help debug applications. It will soon enable deploying apps to Cloud Run, Google Cloud's serverless platform for running front- and back-end services, and integrate with Checks, Google's AI-powered compliance platform.
Piko is a reverse proxy to connect to external networks. It can be used to expose services in a customer network, as a bring-your-own-cloud service, or to connect to IoT devices. The proxy server may be hosted as a cluster of nodes for fault tolerance, scale, and zero downtime deployments. Piko was designed to serve production traffic rather than as a tool for testing and development.
Google kicked off its I/O developer conference with a two-hour presentation containing a rapid-fire stream of announcements. This article summarizes these announcements into an easy-to-read list. The announcements include Firebase Genkit, an addition to the Firebase platform aimed at making it easier for developers to build AI-powered applications in JavaScript/TypeScript; LearnLM, a family of generative AI models fine-tuned for learning; AI-generated quizzes on YouTube; a new discovery feature for apps in Google Play; scam call detection; Ask Photos, a feature that lets users search across their Google Photos collection using natural language queries; and much more.
In this thread, developers discuss how they feel about AI technology and its impact on their careers. Advances in AI may leave some developers feeling disillusioned. Some developers feel that whatever they build will just get gobbled away by some big tech company. AI is de-democratizing tech in a big way - a handful of giga-scale companies hold all the cards. The field is still very much in its hype phase, so while the technology is impressive, there is still a lot it cannot do.
