Parents can limit how teens use channels, whose Status they can see, who can see their Status updates, and control who can add teens to groups.

Three days left to exhibit at TechCrunch Disrupt 2026. Book by October 2 at 11:59 p.m. PT to showcase your startup to 10,000+ founders, investors, operators, and tech leaders.

Founded by Apache Flink veterans, the startup is taking on workflow heavyweight Temporal.

At TechCrunch Disrupt 2026, Cerebras Systems CEO and co-founder Andrew Feldman will explore the growing demand for compute, energy, and infrastructure, how Cerebras is approaching those constraints differently, and what comes next if today’s AI hardware reaches its limits.

This conversational AI assistant is intended to provide personalized feedback to creators, rather than generic advice.

Fitbit Air costs around $146 in India, roughly $47 more than its U.S. pricing.

Pledge signed by President Trump and top AI leaders misspells the United States.

The order -- Harbinger's biggest ever -- comes as the startup is reportedly considering an IPO.

Instinct is rolling out human-curated product and travel recommendations, but some users aren’t happy about getting suggestions they never asked for.

Privacy-Preserving Active Learning for heritage language revitalization programs across multilingual stakeholder groups Introduction: When a Dying Language Met Differential Privacy Last spring, I found myself hunched over a laptop at 2 AM, staring at a dataset of 4,200 annotated sentences in Nahuatl — a language with roughly 1.7 million speakers, most of them elders, scattered across central Mexico. A community organization had reached out to me after reading one of my earlier a...

When designing parallel and concurrent systems, developers invariably face a core architectural dilemma: Multi-Process vs. Multi-Threading. If you learned systems programming in C, you likely remember fork() and join() (or waitpid()) as the default primitives for spawning and managing execution units. In the early days of Linux, POSIX thread implementations were notoriously fragile, making process cloning the de facto standard for parallelism. However, as operating systems matured and prod...

1. Introduction — Why Does WebFlux Exist? If you've built REST APIs with Spring MVC, you know the model: one thread handles one request, start to finish. That thread blocks while waiting for a database call, a downstream HTTP call, or a file read. This is called the thread-per-request model, and it works fine — until you have thousands of concurrent, slow, I/O-heavy requests. At that point, you run out of threads, not CPU. Spring WebFlux solves this by using a reactive, non-blocking m...

Tutorial hell doesn't feel like hell. That's the problem. It feels like progress. You watch a video, you type along, the code runs, and you think "I get it." Then you open a blank file and nothing comes. I lived in that loop for a long time. This is how I got out. How to know you're in it You finish a course and immediately start another one You can follow along, but a blank editor freezes you You say "I'll start my own project once I learn a bit more" Your projects...

If you give an LLM access to your code, you write tools. A tool is a function plus what a model needs to call it: a name, a description, and a schema for the arguments. Then you write the same tools again. The first version uses the AI SDK's tool() . The project adds an MCP server, so the tools are rewritten for registerTool . Another team uses Mastra, and the tools are written a third time with createTool . The functions stay the same. Only the wrapper changes. Each wrapper is also tie...

JavaScript Objects and Arrow Functions. Here is a quick breakdown of what I covered: ​1. JavaScript Objects (Key-Value Pairs & Methods) ​Objects allow us to group related data and functionality together. ​Example 1: Mobile Object: const mobile = { brand: "Vivo", price: 15000, network: "5G", browse: function () { console.log("Browsing..."); } } Example 2: Bike Objects (TVS & Bajaj): const TVS = { model: "XL-100", price: 99000, cc...

A Deep Investigation I've been sitting on this project for a while, I haven't shared it until now. While learning about networking and on one of my massive side tangents, I thought it would be really cool to have a detailed breakdown of what the data is doing at what stage in the process. No, not another OSI Model post, but the Wi-Fi 7 NIC exclusively. I wanted to know, "What is the process for the cutting edge Wi-Fi technology?" - something I have limited knowledge about. That's a VERY B...

I build a tool that schedules social posts. This week I added four new places to publish: WordPress, dev.to, Hashnode and Lemmy. Then I had each adapter reviewed by someone who did not write it. The most useful findings were all the same kind of bug: the code said "published" when it had only proven "the server answered". Here are four ways that happens. 1. A 200 is not the post My first version of the read-back check fetched the public page and treated HTTP 200 as "live". Tha...

TypeScript Partial , Required , and DeepPartial in 2026: Which Utility Type Actually Fits Your Use Case This article was written with the assistance of AI, under human supervision and review. Most TypeScript utility type problems stem from teams treating Partial<T> , Required<T> , and DeepPartial<T> as interchangeable shortcuts when each solves a distinct problem. Developers reach for Partial to silence compiler errors during form updates, then spend week...

You asked something. The answer came back polished. Later you found out it was wrong. A statistic that doesn't exist. A citation to a paper nobody wrote. A confident summary of a document that says the opposite. The frustrating part isn't the mistake. It's that nothing in the reply looked like a mistake. No hedge. No wobble. No visible seam. That gap is the thing worth understanding. Once you see why confidence and accuracy have nothing to do with each other, you stop being surprised and st...

People ask it as a yes or no. It isn't one. Not because nobody knows the answer, but because "job" is the wrong unit to ask about. Almost nobody does one thing at work. You do a bundle of tasks, and AI hits each one differently. Some are already mostly automatable. Some are decades out. A few will actually get easier in a way that makes you more valuable, not less. Average all of that into a verdict about your job title and you throw away the information you actually need. So here's the us...

By the end of this post, a pull request that breaks your data will fail in GitHub before anyone can merge it. Most data quality checks run after the data lands. But often, what broke it was a code change approved an hour earlier. So let's check it right there, in the pull request, with three pieces: A data contract in YAML. A Python script that turns it into Great Expectations (GX) checks. A GitHub Actions workflow that runs the script on every pull request. All the files are ...
