SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI. The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models. Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

After 434 Leetcode problems, here's what actually matters in coding interviews: 1. Clarify constraints before coding (array size, negatives, duplicates) 2. Always verbalize brute force first — even if you know the optimal 3. Show your thinking: "Creating result array... iterating through input..." 4. Debug by writing intermediate values in comments, not just reading code The algorithm is maybe 30% of the evaluation. Communication is the rest. Wrote a detailed breakdown with examples 👇 medium.com/proandroiddev/how… #leetcode #codinginterview #softwaredevelopment

🧵 The worst cargo experience of my life - with @LOTPLAirlines This summer, I relocated from Yerevan to London to start work at @X. I shipped 2 bags via LOT's cargo service. One arrived. The other - with all our winter clothes - vanished in Warsaw. No call. No email. No updates. No official lost baggage documents. Just "formal" responses saying they're "searching." After 21 days of unsuccessful "searching", we filed for compensation. LOT's response? We submitted "too late" and we might be scammers. Seriously?? After THEY lost our belongings and never contacted us? @LOTPLAirlines - is this how you treat customers? Lose their property, ignore them, then accuse them of fraud? Please like and share for visibility, especially my Polish friends 🇵🇱 @AdamLowisz @matiwojt

Это сильно, конечно. Надеюсь, человек такое написал просто, чтобы хайпануть.

Непопулярное мнение, но руководителей действительно бессмысленно хвалить. Если работа делается хорошо, они и так в курсе. Важно давать жесткую критику. Чем жестче тем лучше
