"it's Python, you do anything and it allocates" How true is this? I modified CPython to print when it allocates an integer object Then added numbers in a for-loop 100k times My terminal got spammed with 101006 allocations Why? Let's explore the internals of CPython: #FrontendDev

you don't even need Pangram to know if Rust was LLM authored, just check for "use" inside the function definition

nobody will tell you this... but your AI agent is probably slower and dumber because you gave it too many subagents Anthropic's own team tested it: one agent with skills often beat the multi-agent setup on quality, cost and speed - ~2x faster runs for one customer - 80%+ smaller Claude Code system prompt on newer models - tool choice breaks past 30-50 tools paste this prompt to fold your subagents back in the way Anthropic recommends: ----------------------------------------------------- audit my agent setup and fold my subagents back into one main agent. don't edit any files until i say ok. 1. MAP: list every subagent with its prompt, its tools and when it gets called. flag any that chain on each other's output, touch the same data, or usually run together. 2. SKILLS: turn each subagent's instructions into a skill. give each one a one-line description of when to use it, and load the full steps only when they're needed. 3. TOOLS: turn the API calls into tools grouped by what the user is trying to do, not one tool per API. keep the total under 30. 4. TESTS: before changing anything, write 10 test tasks that cover every chain of agents and every rule the agent must never break. 5. FOLD: fold in one subagent at a time. run every test task twice. keep a subagent only if the folded version scores worse, it needs fresh context for parallel work, or the main agent's context gets bloated without it. show me the full plan first and wait for my ok. ------------------------------------------------------

Finally switched from opencode to omp + deepseek. Best setup I've run. opencode was burning through tokens and acting like it was running good models when it was quietly routing to cheap, bad ones underneath. On top of that, the harness is missing simple stuff that would make anyone's job easier. Honestly just bad. I paid them a lot and they don't deserve it. Best investment you can make in yourself, and it's an easy weekend project. Thanks @can1357, you built something amazing.

‼️ A bug bounty hunter says they rooted their 2025 Samsung TV with zero-days and found an AI model tracking what they watch and the ads they skip. The TV also takes screenshots, categorises audio and can tap a soundbar's mic, they say. Then OpenAI banned them for "Cyber Abuse".

Holy shit! The Claude Desktop app has improved so much since the last time I used it. A popup side chat makes total sense. I'm a CLI guy, but I've only used the desktop app for the past 2 days, and I can't go back.

REA is most dangerous thing on the internet right now... It lets your AI agent reverse engineer any app, down to the binary If you use it correctly, you can rebuild any feature you pay for, for FREE In this article, I show you how:

While I reverse engineering my Wi-Fi router, Claude found f*cking scary privacy problem... Internet provider sees every site I open and can change anything in my router without asking me here's what else it found and 5 steps to fix yours: what Claude found: • my router keeps a list of 29 devices that ever touched my Wi-Fi and see when new connects • my provider can reach into my router any time, Claude found channel hiding in my connection name, and I have no way to turn it off • every site I opened was looked up though my provider in plain text • my provider's app on my TV box kept sending data while TV was off • and much more... and it's not just me: - about 1 billion devices have this remote channel (University of Innsbruck) - researhers pulled 2 billion+ router locations from Apple's Wi-Fi database, accurate to meters (University of Maryland) how to fix yours: 1. install repo below (It also helps improve Wi-Fi speed) and send Claude Code a photo of your router 2. change admin password from the one on the sticker 3. turn on encrypted DNS, your provider stops seeing your lookups 4. turn on Private Wi-Fi Address, your phone stops showing its real ID to every router 5. add _normal to your Wi-Fi name, Apple and Google stop adding it to their location maps Do it as soon as possible. Then read article below on how to find these problems in other tech:

Last week I got Opus 5.5 and GPT-6 Astra to separately build me a 3D game engine in C++ from ONE prompt - a short markdown doc with some basic requirements. Opus 5.5 worked for 36 HOURS STRAIGHT and produced not just a fully functional 3D game engine, but TWO great quality games to go along with it. Astra worked for 1.5 hours and produced a basic starting point. Not sure why it stopped, but the basic engine was there. No idea what the code looks like (yet) - keen to do a code review and find out. This is one of the games that Opus 5.5 built in the "Basalt" engine, as it called it. This is my reaction to seeing it for the first time.

I've added /retro into the "Main Flow" of my skills - I consider it that important. Even running it on a 'successful' agent session can turn up inefficiencies and workarounds the agent is battling against. aihero.dev/skills-retro

JOIN vs Subquery.. Both can be used to retrieve related data from multiple tables. But what exactly is the difference? When would you use a JOIN instead of a subquery? And the interesting one: Is a JOIN always faster than a subquery?

Rails 8.2 provides a way to access ENV, .env, and credentials all in one place. Wish we had this years ago.

I asked Claude to replicate Excel 97 in its entirety, and it did it in about 10 minutes. I've been playing around with it for a while and I can't find any faults. THIS IS A SINGLE 11 WORD PROMPT!! How can anyone possibly think AI hasn't arrived yet???
