You'd be forgiven for thinking this day would never come. Siri has spent a decade and half somewhere between "sort of useful at a few things" and "utterly disastrous, why did I even try, can it honestly not even set a timer." But the wildest thing just happened: Apple put out a new version of […]

The IPO market is back, and it’s not the same companies leading the charge. FAANG had a good run, but a new acronym is taking over: MANGOS — Meta (or Microsoft, depending on who you ask), Anthropic, Nvidia, Google, OpenAI, and SpaceX. Half of that bunch is heading to public markets in the same window, and it’s a stress test for investors, for valuations, and for […]

Today on Uncanny Valley, we take an early look at the SpaceX IPO and why you might find yourself among the investors without even realizing it.

Your pods keep getting killed. Not crashing — killed. One moment they're running fine, the next they're gone and Kubernetes is spinning up replacements. You check the logs and there's nothing useful. The pod just… disappeared. Turns out Kubernetes killed it on purpose. And if you don't tell it how much memory your app actually needs, it'll keep doing it. Why Kubernetes evicts pods Kubernetes runs on nodes — physical or virtual machines that host your containers. Each node has a finite amount of CPU and memory. When a node runs low on resources, Kubernetes has to make a choice: which pods stay, and which ones get evicted to free up space. The decision comes down to QoS classes — Quality of Service tiers that Kubernetes assigns to every pod based on how you've configured resource requests and limits. There are three classes: BestEffort — no resource requests or limits defined. Kubernetes has no idea how much CPU or memory the pod needs. These get killed first. Burstable — requests and limits are defined, but they're different (e.g., requests: 256Mi , limits: 512Mi ). The pod is guaranteed the request amount, but can burst up to the limit. Killed second. Guaranteed — requests and limits are set to the same value. Kubernetes reserves exactly that amount of resources for the pod. Killed last. If your pods don't have resource configuration at all, they're running as BestEffort. And when the node hits memory pressure, BestEffort pods are the first to go — no questions asked. The Guaranteed class Setting your pod to the Guaranteed class is one line in your deployment config. Define requests and limits for both CPU and memory, and make them identical: resources : requests : memory : " 512Mi" cpu : " 500m" limits : memory : " 512Mi" cpu : " 500m" That's it. Kubernetes now knows this pod needs exactly 512 MiB of RAM and half a CPU core, and it reserves that capacity when scheduling the pod onto a node. If a node doesn't have 512 MiB available, the pod won't be placed there. An

This article was originally published on hawksley.dev . I've owned the domain name hawksley.dev for a while now, but I've never done much with it aside from sending email. Over the weekend, I thought I might as well make good use of it and decided to create a blog. In the beginning, this site had a humble home page with some links to GitHub projects. A blog requires much more infrastructure for me to use it effectively. For one, it'd be great if I could just write my posts in Markdown and have them formatted by my project automatically. Having a look at the options available, the first that stood out was GitHub's Jekyll . It looked nice and had great integration with GitHub Pages, which I'm hosting with at the time of writing. However, it just felt too rigid. I needed something modern that I felt I could get my hands dirty with. Enter Astro. Why Astro In the grand scheme of things, the Astro framework is pretty new at just 5 years old. That hasn't prevented it from gaining popularity rapidly. It holds performance as a key design principle, anything that can be static will render statically. By default, it ships absolutely no JS to the browser, which felt perfect for my use case. I have no need for advertising or heavy tracking scripts weighing down my site. All I need is a place to write. Learning how to work with Astro was completely painless. I created a new GitHub repository and followed along with their very high-quality documentation to create a blog of my own. At the very end of it, I’d created a nice neat blog that loaded instantly and was easy to write for. I wasn't satisfied by using the tutorial's blog for my site, though, as it felt too cookie-cutter, and so I started again, now with confidence in the framework. The Design Decisions There were some definite design decisions I knew I wanted from the get-go. First-class light mode and dark mode support were a must. Plenty of blogs offered just one or the other, and after a bit of digging, it didn't seem tec

In 2025 Google Cloud added G4 , powered by NVIDIA's RTX PRO 6000 Blackwell Server Edition GPUs to their offering, allowing them to offer hardware not only for AI applications, but also for other applications, such as rendering, simulations or gaming. A single G4 instance with one accelerator ( g4-standard-48 ) comes equipped with 48 CPU cores, 180 gigabytes of RAM and 96 gigabytes of GPU memory. This is a lot of resources for a single cloud workstation, that only the most demanding workstreams would utilize. Most professionals who require a graphics accelerator to do their job, don't really need this much compute power for day to day tasks. It wasn't financially reasonable to pay for a G4 instance, when you weren't utilizing all the resources you paid for. If only there were smaller machine types… If only you could share that one very powerful GPU between multiple virtual machines… Introducing fractional VMs! During Google Cloud Next 2026, Google announced GA for fractional G4 VMs and was the first provider to bring vGPU functionality to RTX PRO 6000 accelerators. vGPU stands for virtual graphical processing unit . Just like VMs (virtual machines) are a way to split one physical computer into smaller, independent systems, vGPU allows for a single physical accelerator to be split into 2, 4 or 8 virtual accelerators! The new fractional machine types ( g4-standard-24 , g4-standard-12 , g4-standard-6 ) now allow you to perfectly match the compute capabilities to your needs! Who is it for? The existence of those new machine types makes it much more cost-efficient to move many GPU-dependent tasks to the cloud. Replacing physical workstations in offices with cloud infrastructure is not a new thing , but till now, Google Cloud didn't offer a good platform for those who needed workstations to process images, post-process videos, simulate physics or render 3D graphics. Those users now can get exactly the hardware they need, allowing their companies to move away from maintaini

If you've ever spun up an EC2 instance for a side project, accessed a remote work desktop from your personal laptop, or stored files on Google Drive without thinking about the physical hard drive it lives on, you've used virtualization. As the foundational technology behind all modern cloud computing, virtualization transformed how we build, deploy, and manage IT infrastructure—cutting hardware costs significantly for enterprises and making on-demand scalability a reality for teams of all sizes. In this guide, we'll break down exactly what virtualization is, how it powers the cloud, the 6 core types of virtualization, and best practices to implement it safely and efficiently. Table of Contents What is Virtualization in Cloud Computing? Core Virtualization Concepts You Need to Know Role of Virtualization in Cloud Computing 6 Key Types of Virtualization (With Use Cases) Top Benefits of Virtualization for Teams of All Sizes Virtualization vs. Related Technologies Virtualization vs. Cloud Computing Virtualization vs. Containerization Common Virtualization Challenges and Mitigations Real-World Virtualization Use Cases Virtualization Best Practices Conclusion References What is Virtualization in Cloud Computing? Virtualization is a technology that creates virtual, software-based representations of physical hardware (servers, storage, networks, etc.) and abstracts these resources from the underlying physical machine. A software layer called a hypervisor separates operating systems and applications from physical hardware, allowing multiple isolated, self-contained systems called Virtual Machines (VMs) to run simultaneously on a single physical host. Each VM has its own virtual CPU, memory, storage, and network interface, and operates independently of other VMs on the same host. For cloud providers, this technology is the backbone of all on-demand infrastructure services, allowing them to share physical hardware across thousands of customers securely and efficiently.

In the previous article, we connected our FastAPI application to a database using SQLite and SQLAlchemy. We also used classes like: class StudentCreate ( BaseModel ): name : str department : str cgpa : float without fully understanding what was happening behind the scenes. Today, we'll fix that. If you haven't read it check it out: FastAPI for AI Engineers - Part 3: Connecting to a database Ananya S Ananya S Ananya S Follow Jun 6 FastAPI for AI Engineers - Part 3: Connecting to a database # ai # fastapi # python # backend 6 reactions Add Comment 6 min read Why Do We Need Data Validation? Imagine you're building a weather application. A user asks: What is the temperature in Chennai? A valid response might be: 35 or 35°C But what if the API returns: Sunny This is clearly wrong. Temperature should be represented as a number. Even if the value itself is inaccurate, we still know that temperature must be numeric. This is where validation becomes important. Validation allows us to define rules about what data is acceptable before it enters our application. For example: Temperature should be numeric Age cannot be negative CGPA should be between 0 and 10 Email addresses should follow a valid format Without validation, applications can receive invalid data and behave unexpectedly. The Problem Without Validation Consider a student registration API. @app.post ( " /student " ) def create_student ( student ): return student A user could send: { "name" : "Ananya" , "cgpa" : "Excellent" } The API would accept it. But a CGPA should be a number, not text. As applications grow, manually checking every field becomes difficult. We need a better solution. Enter Pydantic Pydantic is a Python library used for data validation. FastAPI uses Pydantic extensively behind the scenes. Instead of manually validating data, we define a schema. from pydantic import BaseModel class Student ( BaseModel ): name : str cgpa : float Now FastAPI knows: name must be a string cgpa must be a floating-point nu

https://www.youtube.com/watch?v=VD9zEKQEJxo 这视频深入拆解了人工智能强化学习之父、图灵奖得主理查德·萨顿（Richard Sutton） 在2026年5月共同发表的一篇仅有7页、零算法、零跑分的哲学立场论文。这篇论文提出了 “行动认知 AI”（Enactive Artificial Intelligence，简称 Enactive AI）的概念，并在科技界和资本圈引发了巨大震动（甚至让红杉、英伟达、谷歌联合下注了11亿美元成立新公司）。 视频从 核心概念、哲学脉络、理论内在矛盾、认知科学质疑 以及 产业界的三路对赌 五个维度，极其详细地复盘了视频的所有核心内容： 一、 什么是“行动认知 AI”（Enactive AI）？ 视频强调，全网很多地方都把 Enactive （行动认知/生成认知）和 Generative （生成式 AI，如 GPT、Sora）混淆了，但两者的底层逻辑恰恰相反 [ 00:50 ]： 生成式 AI（Generative AI）： 核心是 续写和预测 。通过已有画面或文本，被动地去预测下一帧、下一个词长什么样 [ 01:07 ]。 行动认知 AI（Enactive AI）： 核心是 在互动中现生成认知 。认知不是大脑被动接收信号并建立静态世界模型，而是“你动了手，世界才向你显现” [ 01:47 ]。 > 举例： 人去拿杯子，不是眼睛先拍下一张静态照片让大脑去死算距离、角度 [ 01:53 ]，而是手往前探的过程中，随着角度、光影的实时动态变化，杯子的形状和可抓取性才在动作里一点点“长出来” [ 01:59 ]。 感知和行动硬死在一起，无法拆分。 这套理论源自认知科学中的 自创生（Autopoiesis）与自主性（Autonomy） [ 02:21 ]。它认为智能体应该像生物一样自我维持、组织，由内在生存需求去塑造感知，而不是一个干等着外部指令输入输出的机器 [ 02:24 ]。 二、 萨顿为什么要发这篇哲学论文？ 萨顿并不是一时性起，这是他为了对抗当前“大模型路线”打出的最后一张哲学底牌： 2019年《苦涩的教训》： 主张人类手写规则干不过堆算力、让机器自己学的通用方法 [ 02:47 ]。 2024年《大世界假设》： 真实世界远比静态内部模型复杂，智能体必须在运行中实时学习 [ 02:59 ]。 2025年《经验时代》： 人类数据是有限的，AI 必须靠自己生成自己的经验长大的 [ 03:12 ]。 2025年9月： 直指整个 AI 行业走错路，大模型堆数据去超智是死路一条 [ 03:19 ]。 这篇论文补上了最后一把火： 之前的论证全是算力、数据和复杂度的“机械账” [ 03:25 ]。而这一次，他第一次把强化学习（RL） 和 认知科学（行动认知）接在了一起，从本体论层面证明： 大模型路走不通，认识世界这件事本身，就只能通过行动和互动的经验来发生 [ 03:39 ]。 为此，2026年初论文共作者创办了 Ineffable Intelligence 公司，号称要造出完全不需要人类数据、靠自己学习的 AI，直接拿到了红杉、英伟达、谷歌 11 亿美元的巨额融资（估值 51 亿美元） [ 03:55 ]。 三、 论文隐藏的两大致命致命逻辑“回旋镖” 视频话锋一转，指出萨顿借来的这套哲学地基里，埋着两根砸中他自己的“大柱子”： 柱子 1：砸中了萨顿的“奖励假设”（自相矛盾） [ 04:35 ] 强化学习的号称教条： 奖励假设（Reward Hypothesis），即所有目标、意图都可以写成“最大化外部给定的标量分数” [ 04:53 ]。David Silver 甚至喊出“奖励就够了” [ 05:13 ]。 行动认知哲学的教条： 自主性（Autonomy），即什么是好坏、成败，标准必须从智能体随时会散架的“物理组织和生存危机”中自发长出来，不能由外部权威操控 [ 05:27 ]。 裂缝： 标准强化学习的奖励函数（Reward Function）是人类设计者用代码硬塞进去的（他律） [ 05:55 ]；而生物判断好坏是为了顶住熵增、维持结构不崩（自主） [ 06:11 ]。论文里作者自己也承认：强化学习的评估标准依然由外部奖励定义 [ 06:38 ]。 内驱动机能救场吗？ 比如好奇心驱动或求知驱动。视频认为不能，因为诸如“优化预测误差”的总结优化目标，依然是人类在架构层死死规定好的，根本不是智能体出于生存忧关的自发需求。没有真正的生命威胁，就没真正的意义生成 [ 07:12 ]。 柱子 2：砸中了萨顿自己的《苦涩的教训》 [ 07:49 ] 萨顿当年痛骂：研究者总忍不住把人类以为的思考结构（比如语法树、手工特征检测器）硬塞进 AI 架构里，这长期必被碾压 [ 08:13

In Modern Time applications are no longer simple monolithic systems. Today organizations run: Microservices Kubernetes Containers Serverless Functions Multi-Cloud Platforms Distributed Systems As infrastructure becomes more distributed, troubleshooting becomes significantly harder. A single user request may travel through: Frontend ↓ API Gateway ↓ Microservice A ↓ Microservice B ↓ Database When something breaks, the biggest challenge becomes: "What exactly happened?" This is where Observability becomes critical. 🔗 Resources ** Support the Journey on GitHub: If you're following along, consider starring and forking the repo:** https://github.com/17J/30-Days-Cloud-DevSecOps-Journey What is Observability? Observability is the ability to understand the internal state of a system by analyzing the data it produces. In simple words: Can we understand what is happening inside our systems? Observability helps engineers answer: Why is the application slow? Which service is failing? Which request caused the issue? What changed recently? Where is latency occurring? Without observability: Problem Exists ↓ Guessing Begins With observability: Problem Exists ↓ Evidence Available ↓ Faster Resolution Why Observability Matters Modern cloud-native systems generate enormous amounts of data. Example: 100 Microservices ↓ Millions of Requests ↓ Thousands of Containers Traditional monitoring alone is no longer sufficient. Organizations need: Visibility Insights Correlation Root Cause Analysis Observability provides all of them. Monitoring vs Observability Many people confuse monitoring and observability. Monitoring asks: What is wrong? Observability asks: Why is it wrong? Example: Monitoring: CPU Usage = 95% Observability: Which service? Which request? Which dependency? Which deployment caused it? Observability provides context. The Three Pillars of Observability Modern observability is built on three primary pillars. Metrics Logs Traces Or: Monitoring Logging Tracing Together they provide a

If you’ve ever spent hours debugging slow EC2 workloads or getting sticker shock from unexpected EBS IOPS charges, you’ve probably wondered if there’s a better storage option for temporary, high-performance data. AWS EC2 Instance Storage (also called Instance Store) is one of the most underutilized but powerful tools in the EC2 ecosystem—if you know how to use it correctly. This guide breaks down everything you need to know: core concepts, performance optimizations, use cases, limitations, and how it stacks up against EBS. By the end, you’ll be able to cut storage costs, boost workload performance, and avoid costly data loss mistakes. Table of Contents What Exactly Is AWS EC2 Instance Storage? Core Concepts of EC2 Instance Store Key Features That Make Instance Store Stand Out Which EC2 Instance Types Support Instance Store? Deep Dive: NVMe SSD Instance Store Volumes SSD Instance Store Performance Best Practices EC2 Instance Store vs EBS: Head-to-Head Comparison Top Real-World Use Cases for EC2 Instance Store Critical Limitations to Avoid Costly Mistakes Production-Grade Best Practices for Instance Store Root Volume Options: EBS-Backed vs Instance Store-Backed Instances EC2 Instance Store Pricing: No Hidden Costs Conclusion References What Exactly Is AWS EC2 Instance Storage? EC2 Instance Store is temporary block-level storage that is physically attached to the host server running your EC2 instance. Unlike standalone storage services like EBS, EFS, or S3, it is part of the EC2 service itself, with no network overhead between your instance and the storage disks. Its defining trait is its ephemeral nature: data stored on Instance Store only persists for the lifetime of the associated instance. If you stop, hibernate, or terminate your instance, all data on Instance Store volumes is permanently deleted. Core Concepts of EC2 Instance Store Before you start using Instance Store, make sure you understand these foundational rules: Device naming : Instance Store volumes are

We're likely to see more price increases as the big AI companies plan to go public.

I built something I desperately needed: daily AI audio lessons from real developer trends (plus a Dutch coach for inburgering B1). The hardest part wasn't the AI. It was figuring out how to score genuine rising skills vs. one-day noise. I ended up building a cross-day momentum signal that rewards skills accelerating over 3+ days and dampers spikes. But I'm stuck on the next problem: how do you personalize this without storing user data? (I'm privacy-first, so no subscriber DB — Telegram holds the member list.) If you've solved this, I'd love your take. And if you're learning Dutch + coding, I'd appreciate you trying it and telling me what's useless. What I'm curious about: Is the momentum signal actually working — am I surfacing real trends or just noise? Would the Dutch coach be useful for expat developers in NL, or is it too niche? Technical details (for those who care): • 7 sources: GitHub Trending, HN (Who-is-Hiring + front page), Stack Overflow tag deltas, dev.to, Reddit, Lobste.rs • Map-reduce skill extraction with deterministic attribution (corpus scan, not LLM tally) • Grounded briefs: reads actual source text via Jina + Exa, cited sources • Delivered via Telegram (audio + PDF), Spotify podcast, email • Privacy: PII redacted at ingestion, no subscriber data stored Live: https://yusuprozimemet.github.io/LearnX-Radar/ GitHub: https://github.com/Yusuprozimemet/LearnX-Radar (P.S. This is still beta — I'm looking for feedback, not users. If you try it, tell me what's useless, not what's good.)

Most organizations still think of the hypervisor as a resource abstraction layer. CPU. Memory. Storage. The platform that decides where workloads run. That mental model is increasingly incomplete. Every major virtualization platform — vSphere, AHV, Proxmox — has been steadily accumulating policy enforcement responsibilities. The hypervisor isn't just deciding where workloads run. It's increasingly deciding what they're allowed to do. The Speed of the Shift Is the Real Story Virtualization practitioners already know security controls have moved downward through the stack. What's less appreciated is how compressed the most recent phase has been. For years, hypervisors enforced resource allocation. Within a single platform generation cycle, that same layer accumulated encryption policy enforcement, workload trust validation, microsegmentation, secure boot enforcement, host attestation, and workload isolation boundaries — not as optional add-ons, but as core platform capabilities. The perimeter-to-OS transition took decades. The hypervisor accumulated a comparable policy enforcement surface in the time between one major vSphere release and the next. That compressed timeline is what creates the ownership lag — the governance model adequate for a resource scheduler has not caught up to a platform that enforces organizational policy. The Hypervisor Now Makes Binding Decisions The distinction that matters: a platform that observes policy versus a platform that enforces it. The hypervisor is no longer observing. It is enforcing. VM fails attestation → workload does not start. Encryption policy mismatch → workload cannot migrate. Segmentation policy violation → communication blocked at the platform layer. Trust validation failure → host removed from workload eligibility. Those are not scheduling decisions. Those are governance outcomes. The workload doesn't get a vote. This is what makes the hypervisor governance infrastructure : infrastructure that directly enforces organiza

The IaC landscape split into two philosophies about a decade ago and hasn't fully resolved the argument since. On one side: declarative configuration languages designed specifically for infrastructure (Terraform HCL, CloudFormation YAML, Bicep). On the other: general-purpose programming languages brought to infrastructure (AWS CDK, Pulumi). Both approaches have won in production at major organizations. Neither is clearly superior. This comparison covers Terraform, AWS CDK, and Pulumi in depth — how they work, where they excel, where they struggle, and which makes sense for different team situations. It isn't a beginner introduction to any of these tools; if you're choosing between them for a real project, this assumes you've at least skimmed each one. The core philosophical difference Terraform's HCL is a purpose-built configuration language. It's not Turing-complete (no arbitrary loops, no recursion, limited conditionals). This is by design: HashiCorp's position is that infrastructure definitions should be readable, predictable, and safe to generate tooling around. When you read a .tf file, you can understand what it creates without executing anything. CDK and Pulumi take the opposite position: the limitations of configuration languages are a tax on productive engineers. Why invent a domain-specific language when TypeScript already exists? Real programming languages have proper abstractions, test frameworks, package managers, IDE support, and a billion engineers who already know them. Infrastructure should be no different from application code. Both positions have merit. The choice between them often comes down to who's writing the infrastructure more than which approach is technically superior. Terraform Terraform is the default choice for infrastructure-as-code in 2026. It works with every major cloud provider and hundreds of minor ones. The Terraform Registry has thousands of modules — reusable packages for common patterns like VPCs, EKS clusters, and RDS databa
