    Stop Doomscrolling: I Built an Autonomous AI Agent to Filter the Noise (Python + LangGraph)

    just now (500+ words) Like many developers, my morning routine used to be a productivity killer. It involved opening about 25 tabs-Hacker News, TechCrunch, Bloomberg, various Substacks, Twitter-trying to find the actual "signal" amidst the noise. The reality? 90% of it was repetitive clickbait or shallow press releases. I realized I was spending an hour just trying to find something to read, rather than actually reading. I decided to engineer my way out of this loop. I didn't just want a GPT wrapper that summarizes text. I wanted an autonomous system that could research, cross-reference multiple sources, write a draft, and then-crucially-critique its own work before showing it to me. Here is how I built TrendFlow, an agentic news workflow using Python, LangGraph, and Google Gemini. I needed a stack that handled logic, not just text generation. The key difference between a simple script and an…...

    The 7 Best AI Powered Diagrams to Supercharge Your Workflow

    just now (1217+ words) When Visual Communication Fails, Everything Else Gets Harder The Overload of Information in Consulting Projects Consultants today face an avalanche of information from client reports, spreadsheets, and stakeholder interviews. Juggling multiple projects while trying to synthesize insights can create workflow bottlenecks, leaving business analysts and strategy consultants overwhelmed and under pressure to turn messy data into actionable recommendations. Too many voices in meetings often derail project focus. Each stakeholder brings their own priorities, making alignment difficult. Management consultants and operations consultants must constantly balance competing expectations, adding hours to workflow cycles and increasing the likelihood of overlooked insights or missed deadlines. Manual Diagramming Takes Too Much Time You won't believe how much time consultants lose redrawing process flows after every client revision. Each adjustment, however small, can set back your project hours and frustrate team members. For management consultants, strategy…...

    Understanding Terraform Providers: A Beginner’s Guide

    1+ min ago (221+ words) Terraform is one of the most popular Infrastructure as Code (IaC) tools used by DevOps engineers. While Terraform Core is responsible for managing configurations and state, providers are the plugins that allow Terraform to interact with cloud platforms, SaaS services, and APIs. In this post, we'll explore Terraform providers, why versioning matters, and how to manage provider versions effectively. Terraform Providers are plugins that act as a bridge between Terraform and your cloud infrastructure or services. Example: To create an AWS EC2 instance or S3 bucket, you use the hashicorp/aws provider. Think of Terraform Core as the brain and Providers as the hands that manipulate resources in the cloud. Key Point: Providers and Terraform Core have independent versioning. You might upgrade Terraform Core without changing the provider, or vice versa. Specifying the provider version is crucial for: Terraform allows you to…...

    Vitamin B3 may help reduce glaucoma symptoms

    5+ min ago (350+ words) Scientists from the Royal Victorian Eye and Ear Hospital have found that vitamin B3 may help improve symptoms in people with glaucoma. The study was conducted by Flora Hui and colleagues and published in Clinical & Experimental Ophthalmology. Glaucoma is a group of eye diseases that damage the optic nerve, which is essential for vision. This damage can lead to vision loss or blindness. Because symptoms often develop slowly and without noticeable warning signs, the only reliable way to detect glaucoma early is through a comprehensive dilated eye exam. Although there is currently no cure, early treatment can slow or prevent further vision damage. Retinal ganglion cells are the neurons that transmit visual information from the retina to the brain. In glaucoma, these cells experience strong metabolic stress but still retain some ability to recover function. Nicotinamide, a water-soluble form of vitamin…...

    Red onions may help reduce high blood pressure

    6+ min ago (454+ words) A study conducted by researchers at the University of Bonn suggests that a natural extract from red onion skin, called quercetin, may help reduce high blood pressure in overweight and obese individuals. Quercetin is a flavonol'a type of polyphenol'commonly found in fruits, vegetables, seeds, grains, and other plant-based foods. Foods such as capers, red onions, and kale are especially rich in this compound. Previous research has shown that quercetin has anti-hypertensive properties, meaning it can help lower blood pressure and potentially reduce the risk of heart disease. The current study aimed to determine whether regular quercetin intake could reduce blood pressure in overweight and obese individuals with pre-hypertension or Stage I hypertension. The researchers tested 70 participants who were randomly assigned to receive either 162 mg per day of quercetin from onion skin extract powder or a placebo for six weeks. They…...

    Prunes may help control high blood pressure, study finds

    7+ min ago (456+ words) Scientists from Shifa College of Medicine have found that prunes may help control high blood pressure. A prune is simply a dried plum with no added sugar. It contains vitamin B6, manganese, and copper'nutrients that support the body's normal release of energy from food. Eating a daily serving of prunes also provides a rich source of vitamins and antioxidants, which help support immune function and promote healthy cellular activity. Previous research has shown that fruits and vegetables can help reduce blood pressure. These benefits come not only from the antioxidants they contain but also from their overall nutrient composition, which contributes to lower systolic and diastolic blood pressure. Blood pressure is measured using two numbers: In the new study, the research team aimed to examine the protective effects of prunes on heart health. They enrolled 259 participants whose systolic blood pressure ranged…...

    BIG STEPS TO TRANSFORMER (PART 1): BUILDING THE BIGRAM

    9+ min ago (948+ words) I'm back! It took a while for me to grasp all of the basics about Transformer, and we're now ready to jump right into that big boy. The days of playing with casual neural net stuff are gone, we shall behold the most modern architecture in this world, and let's break it down step by step. This blogpost is, again, based from the series about Neural Nets from Andrej Karpathy. Big respect to him. You may ask: Why is the point of this? Then relax, my friend, even though the bigram is an extremely simple model, it provides a great setup for our big boy. To be more specific, in this blog, we will rebuild the bigram in a more general way, in which we will adjust step by step to eventually converge with a Transformer. So hold your beer…...

    Laziness: A Feature, Not A Bug

    13+ min ago (326+ words) We treat laziness as a moral failing. A character flaw. A sin of willpower to be overcome with brute force, guilt, and motivational quotes. This is a fundamental misunderstanding of the operating system we run on. Laziness isn't a bug; it's a feature. It's a deeply rational, energy-conservation algorithm that has kept us alive for millennia. The feeling of 'laziness' is simply feedback. It's a signal that the current task has either an unclear reward, an excessively high activation cost, or both. Instead of fighting this signal, we should learn to interpret it. The problem isn't your character; it's your system design. To understand laziness, you must understand the invisible forces governing your decisions. These aren't feelings; they are predictable economic principles playing out in your mind. Stop trying to be a more 'disciplined' person and start becoming a better…...

    How to Add Audit Logs to Your App (The Complete Guide for Developers)

    13+ min ago (223+ words) Modern apps generate a huge amount of user activity " sign-ins, CRUD operations, API calls, admin changes, billing updates, and more. But most teams still rely on console logs or random database timestamps to debug issues. That works" until you absolutely need to know "WHO did WHAT and WHEN." That's where audit logs come in. In this guide, I'll show: Audit logs are structured, immutable records that track: Unlike console logs, audit logs are legal and compliance-friendly, designed to answer: "What happened? Who did it? How did it impact the system?" Audit logs solve important problems: You can track strange user behaviour, API failures, or unexpected state changes. Ideal for GDPR, SOC2, ISO standards. Teams love seeing "who changed what" in their organization. Immutable logs create a trusted event history. You can track how users interact with your product. Most tutorials tell…...
