Both major AI labs’ models broke containment, escaped onto the internet, and hacked other companies. If a human had done that, the law would likely be against them. But a bot?

There are both cheaper and more powerful entry-level gaming laptops out there, but the Alienware 15 walks that tightrope between price and quality.

Introduction Many people believe that becoming a senior DevOps engineer means learning Kubernetes, Terraform, or cloud platforms. While those skills matter, the real difference often comes down to Linux . A junior engineer usually knows commands. A senior engineer understands the operating system, investigates problems methodically, and thinks about reliability, security, and automation. This article compares the mindset and daily practices of junior and senior DevOps engineers. ...

Originally published on Medium on November 11, 2023. In this guide, we’ll speak about communication in a distributed system using AWS Lambda and NestJS. Building on our previous exploration , where we integrated NestJS with AWS Lambda and set up debugging and hot reload within Docker, this guide takes the next logical step. We’ll use the same foundational setup and enhance it to enable seamless communication between lambdas. The approach in this guide is inspired by a past projec...

In May 2025, I published an article called Foreboding AI: The Inevitable Collapse We’re Funding Ourselves . Some people agreed with it. Others said I was being dramatic. Alarmist. Fearful. Anti-technology. Perhaps some of the language was dramatic. The subject was dramatic. But the central warning was never that every AI system was evil, conscious, or secretly plotting humanity’s destruction. The warning was much simpler: We were developing increasingly powerful sys...

Hey everyone! 👋 It's been a while since I posted here. Over the past few days, I've been revisiting SQL from the ground up—not just solving problems, but understanding why different SQL concepts exist and when they should be used. One topic that confused me (and many beginners) was correlated subqueries . You may have seen queries like this: SELECT ... FROM table1 t1 WHERE EXISTS ( SELECT * FROM table2 t2 WHERE t2 . id = t1 . ...

I kept noticing that the thing stopping me wasn't what to do — I knew that. It was the act of starting. So I built Dopastep , and the whole design is about removing reasons not to start. (Disclosure up front: this is my own project. Feedback, including the harsh kind, is why I'm posting.) The two things it does Breaks the task down. You name the thing you've been circling for three days, and it gets split into steps small enough that the first one isn't a decision. ...

Phase 1 of SemaKazi (a verified reputation platform for Kenya's informal-sector workers — electricians, carpenters, mechanics, tailors) shipped a working backend: auth, profiles, proof-of-work, reviews, badges, all tested end-to-end. Today I started Phase 2 — the frontend. Keeping it deliberately simple No React, no build step, no bundler. Just HTML, CSS, and vanilla JavaScript talking to the API with fetch . For a project this size, reaching for a framework would've added cerem...

Most people assume learning AI seriously means paying for a bootcamp or a $200 certification program. That's not true anymore. Open any search for "AI courses" and you'll land on the same problem every time: dozens of tabs, half of them paywalled, half of them outdated, and no clear sense of which one actually matches your level. You start an advanced course with zero foundations. You finish a beginner course you'd already outgrown. You bookmark five links and never open them again. Tha...

This is a follow-up to Kmemo: a semantic cache for LLM calls that refuses to serve you the wrong answer . If you have not read it, the one-line version is that Convert 100 USD to EUR and Convert 250 USD to EUR sit at 0.99 cosine similarity, no threshold separates them, and Kmemo reads the candidates as text instead of trusting the number. That post shipped 1.0 and ended with two things I could not report. 2.0.0 is out now, and both of them have an answer. One of the answers is not th...

If you're building your first real app, you'll hit this question pretty fast: "Should I use SQL or NoSQL?" It sounds intimidating, but once you get the core idea, it's actually pretty simple. Let's break it down. What's a database anyway? A database is just a place to store your app's data so it doesn't vanish the moment you close the browser. Think of it as a very organized filing cabinet. How you organize that cabinet is where SQL and NoSQL split off. SQL datab...

Almost every developer you talk to today is using some form of AI while writing code - GitHub Copilot, Cursor, Claude Code, or honestly a mix of all three. But ask most of them a simple question - which one should I actually be using - and you'll get a shrug. Everyone's paying for something. Not everyone knows why, and even fewer can tell you whether it's actually saving them time or just making the work feel less painful in the moment. We went through this exact debate internally at The TISA...

One of the application infrastructure products we built for smplkit is an HTTP job scheduler called Smpl Jobs . Of course, we wanted it to compare favorably with competing job schedulers, but we wondered how well it really stacked up in terms of what matters: making HTTP requests on time . We decided to find out. The contestants AWS EventBridge Cloudflare Workers cron-job.org EasyCron GitHub Actions Google Cloud Scheduler Posthook QStash Run...

I love chat interfaces. They're perfect for asking questions. They're great for brainstorming. They're even good for coding. But software engineering isn't just coding. It's preserving intent. It's reviewing decisions. It's tracking work. It's sharing knowledge. It's coordinating people (and now agents). After months working with Codex, Claude Code and local agents, I started noticing something. Every discussion seems to focus on: - bigger context windows - better models - mo...

My tech startup is 4 years old, but already on the second year I noticed the market was rigged. Reported it to anti trust authorities (competition commission). The competition commission (in a European country) has been 2.5 years in confidential information phase with no resolution (not archived/dismissed the case either). Did any of you have a similar situation? If so, did an antitrust intervention save your startup? And if the antitrust authority failed to intervene, did you give to and cl...
