In Beijing, they can be the fastest option for trips within a few kilometers, and their growing numbers create all kinds of strategic encounters with the existing traffic system. Watching these games makes me think that AI still has a long way to go before it can imitate them.https://zhaoliangbin42.github.io/en/notes/prompt_txt2img/https://zhaoliangbin42.github.io/en/notes/prompt_txt2img/Sun, 30 Nov 2025 00:00:00 +0800When I started blogging earlier this year, I used GPT-5 to generate images, but the results were still rather plain. Research kept me busy and the blog sat idle for a while. Now Gemini 3 Nano Banana Pro has taken another step forward, and I have a little more time, so I decided to replace the old images and see whether it could handle the job. These are some of the prompts I used; feel free to try them if you like the pictures.https://zhaoliangbin42.github.io/en/notes/tutorial-how-to-use-server/https://zhaoliangbin42.github.io/en/notes/tutorial-how-to-use-server/Sun, 13 Jul 2025 00:00:00 +0800How can researchers work more comfortably with remote Ubuntu servers?https://zhaoliangbin42.github.io/en/notes/reflection-wechat-official-account/https://zhaoliangbin42.github.io/en/notes/reflection-wechat-official-account/Fri, 04 Jul 2025 00:00:00 +0800Content or traffic?
