  • Pre-UC Road Trip — Day 2: Heading to San Diego for UC 2026. I felt a little out of place at first, but I loved the laid-back vibe of La Jolla.

    今天正式开始动手修改 UC Demo 的配置文件,把真正要讲的内容替换成真实数据,也顺便发现了不少配置上的小问题。虽然数据准备依然是目前最大的难点,但至少整体开始进入可以一步步推进的状态了。

    今天 Reinforcement Learning 的讨论会上,我也表达了一个自己的想法:不要因为没有测试数据,就否定一个值得探索的方向,而应该先确定方向,再去想办法准备数据。

    不过,这两天整体状态还是有点低落。总觉得自己做的事情好像没有创造出足够的价值,也还在努力调整心态,希望把 UC 和 Cowork 两边都一步步推进。

    今天早上 7:40 准点送哈妹上学,她今年以来第一次穿裙子去学校,还担心自己是不是“唯一穿裙子的那个”。 这一周状态有点起伏,demo 没做出来让我有点焦虑。 工作上开始把 demo 和 PPT 拆成阶段来做:先 fake data 跑流程,再补真实数据,最后录制。 另外也在重新思考 Cowork 的用户价值。

    今天是 6 月份以来最早送哈妹到学校的一天,也继续坚持学习李宏毅老师的 Reinforcement Learning 课程。Q-Learning 依然有点难,但至少开始建立起整体框架,准备一步一步把 DRL、机器学习和深度学习系统学下来。

    昨天最惊喜的瞬间,是放学路上看到一大片像雪山、棉花糖一样的云;晚上又和朋友一家在小区楼下吃饭聊天,孩子们玩到天黑才回家,这种简单又温暖的生活让我觉得特别珍贵。

    工作上,UC Demo 最大的挑战开始转向测试数据,时间、版权和 Legal 都成了新的难题。接下来继续完善 PPT,再一步步解决 Demo 的问题。

    今天北京依然凉爽,早上从世界杯新闻开始一天——C 罗终于进球,而且一场进了两个。与此同时,我继续学习李宏毅老师的 DRL 课程,开始接触 Q-Learning 的内容。

    工作上,UC 演讲 PPT 基本完成初稿,焦虑感也减轻了不少。与此同时,团队里 Dev 和 PE 的协作终于开始逐渐对齐,从“各做各的”慢慢走向共同完善产品。这或许是比完成一个功能更重要的进展。

    北京因为昨晚的一场雨变得凉爽了不少。 想起昨晚和哈妹聊起天气预报,她第一次意识到天气预报其实是“概率预测”,而不是一定会发生的事实。 早上起来看到梅西再次进球,继续刷新世界杯纪录。随后又学习了一会 PPO 和强化学习课程,把不懂的地方交给 ChatGPT 解释,对理解帮助很大。另外还读到一篇关于 AI 年轻创业者的报道。 晚上打完羽毛球,看到了红红的夕阳,很美。

    端午假期结束,重新回到工作节奏。

    这次一家人去了河北雾灵山和承德自驾游,三天里经历了天气变化、雾灵天路的惊喜风景,以及假期结束前那种熟悉的不舍。虽然总共开了 500 多公里,但旅程并不觉得累,反而收获了很多美好的回忆。

    回到工作后,最重要的任务就是准备 Esri UC 的演讲内容。今天花了一整天梳理 PPT 结构,终于把整体框架搭起来了,焦虑感也少了很多。接下来继续一步一步推进,迎接忙碌但充满期待的一周。

  • 2026年端午自驾游,从北京到河北承德,三天540公里。

    第一天穿过雨幕抵达阿那亚·雾灵山,在农家院的涮羊肉里慢慢安顿下来。 第二天自驾雾灵山景区,沿山路蜿蜒上行,风大云近,像开在天上;随后到承德市区,逛吃二仙居夜市。 第三天走进避暑山庄,在山水与古建筑间收尾,吃了特色的新乾隆酒家。

    返程时有不舍,也有一点假期结束的焦虑,但更多是这一路雨声、山路和家人在一起的踏实记忆。

    今天聊了两件事:学习和放假前的心态。 早上五点多醒来,看了葡萄牙比赛和一些 AI 学习内容。最近越来越觉得,与其追逐每天变化的 AI 热点,不如回到基础,从 Machine Learning、Deep Learning 到 Reinforcement Learning,花时间系统地学一遍。看到“AI by Hands”的学习方式也很受启发——慢一点、亲手推导、真正理解。 下午工作状态有些松散,临近端午假期,总有点心不在焉。简单修复了一些项目问题,也聊到了 GIS Solution、Skills 和产品思路。 接下来三天准备和家人去自驾。

    因为昨晚北京暴雨,电动车没骑回来,所以今天改成走路去上班。

    一路上和哈妹边走边聊红绿灯、电量、车品牌,还被她说成“小骄傲”,还说自己是“不带刺的玫瑰”。

    走路去公司的路上,多了一段很安静的时间,可以慢慢想事情,也挺舒服的。

    2026年6月16日,一日记录。

    今天是一个阴沉但还算平静的早晨,送哈妹去学校,她扎着丸子头去参加“星光小舞台”表演,是第一个节目。

    早上起来的时候,也看到她的手指结痂了,在慢慢恢复,而我自己的手指也在观察恢复情况。

    今天的状态里,有很多关于工作、AI工具、以及系统设计的思考。最近在推进 Cowork 的 map as a context 设计,逐步从 referent → intent → map effect 的链路去打通。

    过程中也看到一些有意思的现象,比如 follow-up suggestion 让系统自动生成地图连线结果,甚至在“看似失败的运行日志”中,最终意外得到正确输出。

    除了工作,也在反思自己对 AI 时代的不自信:很多东西来得太快,反而难以消化,导致表达和分享变得谨慎。但也开始意识到,慢一点、理解清楚一点,可能才是更重要的方式。

    今天是一个阴天的早晨,哈妹早上带着受伤的手指去上学。我生活的节奏又回到了工作日模式,整理这一周的任务:cowork、C3,以及 UC 的准备,同时也要重新把视频剪辑这件事捡起来。

    周末下午在家待了一整天,状态比较疲惫,大部分时间在看电视。 周末还去踢了球,手掌有点轻微受伤,去医院检查后确认问题不大。 这一周事情不少,希望能把节奏找回来,一件一件做完。
