Jitbit condemns this war. I'm from Russia originally and I'm ashamed of my passport right now. Forgive us Ukraine 🇺🇦 💙💛.

This is MS 365 Copilot. Can you guess which tab is selected?

As a founder, nothing makes me more nervous than watching someone review our product on YouTube. Nail-biting, sweating - the full panic mode.😱😱. Sometimes I even ask someone on the team to watch it first, like it's a horror movie and I need a spoiler before I go in.

The wildest part of the AI race - no one has a real moat. Any edge vanishes in months via reverse engineering, talent poaching, or clever hacks. Not even hardware is safe: Nvidia meets Google TPUs, then comes Groq with LPUs. Can't decide if that's terrifying or a blessing.

After ~5 hours comparing inference hosting costs for small LLMs like Gemma/LLaMA, I'm seriously tempted to just buy a damn 24GB Radeon card and run it under my damn desk.

In this new AI world, it's not the coding or fancy MCPs that blow my mind - it’s how search has changed. Like, you ask a weird, rare question:. "Does the visor from the Airoh Commander 2 helmet fit the 2016 Commander?". And it’s like: "brr brr… not really! sources: x,y,z". 🤯.

Tried switching from Cursor back to VSCode + GitHub Copilot. Copilot's still behind. Tab completions got a tiny bit better, reasoning and agent-mode file edits are still worse. Back to Cursor - even if it's lagging on upstream VSCode features/extensions.

Yaak @yaakapp is my new favorite REST client. P.S. Ironically, made by the same guy who built Insomnia, sold it, now making a new one 🤣🤣.

Wow, found an awesome solution on reddit: They run s-core/m-core benchmarks on _all_ cloud servers (not just AWS) and publish a table. Tick "AWS", filter by CPUs/RAM, sort by benchmark results, CPU-GHz, mem bandwidth etc etc. Awesome tool, bookmark it.

AWS is so annoying. You get a 4-core, 16GB server - but nooo, some "m7ax.whatever" will be 3X faster - with *less* cores, *less* RAM and half the price. Because f**k you, that's why. Here's a 10-mile-long list of instance type descriptions, good luck figuring it out.

Looking at Claude Code's pricing, it immediately hits you just how much money Cursor is *burning*. Overdrive mode - just bleeding money. All just to grab more market share. P.S. And honestly, not even sure Claude Code is profitable either. Probably not.

Tried using AI to fill out a vendor questionnaire. "As a large language model Gemini For Workspaces cannot fill blanks in your Google sheets". Wait, WHAT?!!. As we use Cursor, ClaudeCode, MCPs and Agents daily - we forget how far behind "AI for normies" is.

Me: "This method turned out kinda complicated, help me refactor". Cursor: "Nah, it's all clear. Nothing to simplify". 🤨🤨.

The stuff you can do with AI now is actually insane:. -Add ClaudeCode to a GitHub repo.-Mention it in an issue "hey @сlaude fix this".-Go grab a coffee.-Come back to a ready PR. My only problems:.-How the hell do I keep up.-We're all cooked.

Funny how the biggest progress has been in vibeCODING. Not vibe law, not vibe logistics or vibe HRing — coding. Coders be like: “let’s automate our own extinction first”.
