English and Norwegian players will face off under extreme and dangerous levels of heat stress, scientists say, thanks to a Wet Bulb Index over over 90°F.
Ties van der Meer doesn’t know how many siblings he has. The 47-year-old was conceived at a private fertility clinic in the Netherlands using sperm provided by an anonymous donor. After the Netherlands banned anonymous donation in 2004, the doctor who ran the clinic destroyed records that might have identified those donors, he says. He…
New parents obsess over percentile numbers. I get it. I built a tool that plots your baby measurements against official WHO and CDC growth standards. What it does: Weight, height, and head circumference percentiles for ages 0-36 months Visual growth chart showing where your baby falls on the curve Uses WHO Child Growth Standards (0-24 months) and CDC reference data (24-36 months) 35 pages, all pre-rendered for fast loading The hard part: Parsing the WHO growth standard tables into usable JSON. Those tables are dense and not designed for programmatic use. That took more time than building the actual calculator UI. ?? Try it: babypercent.com Built with Next.js, no database, no tracking. Just a calculator that respects your privacy.
Oddly, it wasn't the first time this had happened to the man.
“EMF straws” and similar products are being sold as a way to block electromagnetic frequencies that come from common electronic devices, even without scientific evidence that they work.
We just opened the waitlist for Something, and the part that surprised me most while building it wasn't the multi-agent orchestration — it was how hard it is to make an AI actually disagree. Every model we tested defaults to being helpful, which in practice means agreeable. Even when explicitly prompted to "find flaws," the outputs would soften into "here are some considerations" instead of a real critique. We had to engineer around this specifically: Separate system prompts with opposing reward framing — one agent optimizes for identifying growth potential, the other is explicitly told its only success metric is surfacing a disqualifying flaw Structured output forcing a verdict, not a summary — the skeptic agent (Nothing) has to commit to a specific weakness category (unit economics, timing, technical feasibility) rather than hedging across all of them A reconciliation step where both outputs get merged into one conviction score, so the founder isn't just reading two contradictory paragraphs If anyone's built adversarial agent setups and hit the same "it just wants to agree with me" problem, curious how you solved it.

An image of Portugal forward Pedro Neto’s cleats at the World Cup has reignited a practice among some soccer players: modifying their cleats to relieve heel discomfort.
Some of you may have noticed I disappeared a bit from the community over the last couple of weeks....

There's still a slew of questions about why some people develop alpha-gal syndrome.
The data can help predict what a future pandemic virus might look like.
To start off, I appreciate the community support I have received on the post about being behind. I am behind, and I can't prove it but does it matter?

Rest assure, I will respond to each and every one of you and I am glad to be part of this community! With that said, I want to return the favor to the community about something important. I recently talked to @georgekobaidze and @codingwithjiro in the Virtual Coffee group about life in general. What I notice about our conversation how we ended up talking about regrets and how we should have done this and that. For example, we talked about not networking or not doing beyond the coursework at our University/College because of how non-social we are. Of course, we all have regrets like these and we improve overtime. As we kept the conversation going, there is something that comes down to the root based on the conversations we have and conversations I had overall. One side is that we have regrets and as a result, we improve. We self-reflect on our wants and needs and we improvise from there. For example, for me, I never did networking because of the fear of what other people thinks. I slowly realized that 99% of the irrational thoughts never comes true. Even if it does, I know myself that I could handle the situation. As a result, I took small steps and joined dev.to. We all know where I am at now XD On the other hand, there are people who identifies these regrets they have, but does not act on it. It has become common to college students who says that the "Job Market is Cooked" and that "They are not good enough". To be fair, impostor syndrome is real and yes, the job market is coo
Bullshit is cheap but truth is expensive. Anyone with half a brain cell can post wild misinformation that goes mega viral, which wastes the time and expertise of highly trained people who feel an obligation to inform others of the truth. Today I want you to meet one of those highly-trained people, Dr. Zachary Rubin, […]
TL;DR Tech has taught me many things over the years. It taught me how to learn new technologies, build projects, apply for opportunities, and keep growing. What it didn't teach me was something that turned out to be just as important: how to take care of myself while doing all of those things. For a long time, I believed I would slow down later. Later, when life became less busy. Later, after the next project. Later, after the next opportunity. The problem was that "later" never seemed to arrive. It took an unexpected pause in my own life to realize that building a successful career means very little if we forget to take care of the person trying to build it. Looking back, I don't see that experience only as a difficult chapter. It changed the way I think about success, growth, and what it means to build a career that's sustainable. Today, I still love learning, building, writing, and chasing opportunities. None of that has changed. What has changed is the realization that taking care of myself isn't something separate from my career. It's one of the reasons I'll be able to keep building it for years to come. Along the way, I also realized that many of the things that truly support us are easy to overlook. Rest, movement, nourishing ourselves well, meaningful relationships, and simply checking in on the people around us often receive far less attention than the next framework, project, or milestone, even though they make everything else possible. More than anything, I wanted to write this because I care deeply about this community. I hope none of us have to wait until life forces us to slow down before remembering to take care of ourselves. I hope we build careers we're proud of, but I hope we also build lives we're able to enjoy. This isn't an article about productivity or health advice. It's simply a reflection on something I wish I had understood earlier. Your career matters. So does the person building it. I'd also love to hear your story. Has there been a momen
Holes in socks have become a curious sight at this year’s World Cup. The reasons why are a weird mix of biomechanics, perception, and player habits.
We’ve all been there: it’s 7:00 PM, you’re exhausted after a long sprint, and you open a food delivery app. Your brain screams "Double Cheeseburger," but your body is still recovering from that mid-afternoon sugar spike. What if your phone was smart enough to say, "Hey, your blood sugar is currently 160 mg/dL and rising—maybe skip the extra fries?" In this tutorial, we are building a Chief Health Officer (CHO) Agent . This isn't just a simple chatbot; it’s a sophisticated AI Agent using LangGraph to bridge the gap between real-time medical data (CGM) and real-world actions (Food Delivery APIs). By leveraging automation , function calling , and state machines , we’ll create a system that actively protects your metabolic health. The Architecture: How the CHO Agent Thinks To build a reliable agent, we need a "stateful" workflow. We aren't just sending a prompt to an LLM; we are creating a loop that monitors glucose levels, analyzes food options, and interacts with the browser. graph TD A[Start: Hunger Trigger] --> B{Fetch CGM Data} B -->|Sugar High/Unstable| C[Constraint: Low GI Only] B -->|Sugar Stable| D[Constraint: Balanced Meal] C --> E[Scrape Delivery App Menu] D --> E E --> F[Agent: Analyze Ingredients & GI Index] F --> G[Selenium: Mark/Filter Non-Compliant Items] G --> H[End: Safe Ordering] subgraph "The LangGraph Loop" C D E F end Prerequisites Before we dive into the code, ensure you have the following: LangGraph & LangChain : For the agent's cognitive architecture.

OpenAI API Key : Specifically for GPT-4o’s reasoning and function-calling capabilities. Step 1: Defining the Agent State In LangGraph, everything revolves around the State . Our CHO agent needs to track the current glucose level, the user's health constraints, and the list of available food items. from typing import TypedDict , List , Anno

A large-scale clinical trial has shown that even long-term consumption of DHA—an omega-3 fatty acid found in abundance in oily fish—may not lead to improvements in cognitive function.
TLDR: The most powerful AI on the planet, only a few days of access. Maximize it. I'd first like to give credit where it's due: @trickell - Thank you for sharing Network Chuck's youtube video with me. The reference video is found here guys if you missed it: Network Chuck's Video on Fable I first started by creating a nice template for tech documentation for personal use. It created a beautiful piece of work in about 5 minutes - something I could easily expand on in the future. Here is what it generated for me with after a one or two careful prompts: Clean UI, Easy Navigation! Created this personal reference guide for studying for CCNA (Network Chucks Summer of CCNA) Wanna see it? It lives here: Techdocs But after learning about the true span of Fable's power, I started asking the serious questions, the ones that are life-changing. How can I increase my quality of life based on my resume, experience, and current life circumstances? I wrote about 2 pages of life issues that needed fixing - you know the stuff that slowly eats away at your soul, like student loan debt and people that are challenging to work with? Yes - I told it my biggest issues and instructed it to give me actionable plans that are free or low-cost. Even fable told me that this was a lot. 😅 Getting Organized Knowing the scope of my own problems I knew that my thoughts and processes had to be organized. Luckily for me, I remembered I had a good place to do that. A place that Fable could connect to and place documentation in place for me with checklists, notes, summaries and actionable plans. That app is called Notion, and some of you may have heard of it. No one is going to organize your life for you, no one, except for AI I couldn’t think of a better place for lightning fast critical life-admin documentation on the spot. And I can tell you, this integration works like a charm, and I highly recommend it. For a busy person with a million ideas, this is great. Anxiety Relief I had a tremendous amount of
