@lathelabs Neither, sadly. I tried sniffing nothing and guessing twice — both timed out. Then I just cloned arduino-app-cli and read https://t.co/hhO85k8Tjj. The format was right there: [0, msgid, method, params].Less glamorous than sniffing the inter-chip link, but it worked

Bought an Arduino UNO Q to blink an LED. Ended up reverse-engineering its RPC protocol.

It has a 13×8 LED matrix, so I built a web console — click cells in the browser, the matrix lights up.

The official App Lab couldn't launch custom apps, so I bypassed it.

ai video is everywhere now.
two kinds: multimodal models generating it directly, and llms writing code to generate it.
the video isn't worth anything, the content is.
watch enough of either and it's just fatigue.
mass-produce it fast all you want — still useless.

Many founders today don't fundraise by making investors fully understand the project
They fundraise by making investors fully understand what it costs to miss it

Just tried playing Half-Life on the R36S handheld — the rk3326 chip is actually strong enough to run it!
Plus you can even connect a mouse or keyboard. This little thing is way more capable than it looks. 🎮

@ting_267 感谢！

熟���我的朋友都知道我爱复古掌机，绕不开 RetroArch

最近用它搜游戏，发现搜不了中文，找 ROM 特别麻烦

原因是菜单搜索用的是自绘键盘，不接系统输入法
日文假名、韩文都有键盘页，就是没有中文，为啥呢

因为 24 个谚文、92 个假名能塞进 4×11 的格子
但是常用汉字 3500 多个，塞不进去

然后我换了个思路，做成两级：
· 声母索引页（a–z）
· 每个声母一页常用字，按频率排

字表来自我自己的库：8000 多个游戏名里，实际出现 1500 多个汉字、2 万多次
按拼音首字母分组，组内按出现次数排序

提了 PR 之后，维护者回复：
「Cherry-picked and merged and pushed another patch on top. Thanks」

他还补了一个 commit，修了我漏掉的索引页格数，还有翻页绕圈的问题

@gamescrazy_jj 对，是被逼出来的hhh，RA的屏幕键盘只能一格发一个键码，没有拼音、候选、上屏那一层，做不了百度输入法那种东西，当然考虑到，掌机上大家打的字其实就那么些，那干脆直接铺到第一屏，十字键少翻页就够了

My agent runs my stack.

Ark, Discord, Cloudflare, GSC, QQ, Feishu, WeChat, Baidu Pan — all under one operator.

Not "AI assists me." It manages my life. The interface is the agent now.

@davidpwalter Let me have a try

[Ethan Yeang @EthanYeang]

@Dexmal_AI How did you do it?

机器人公司把大量机器人卖给数据采集公司

数据采集公司雇用一批人遥控这些机器人

采集一大批数据之后，把数据卖回给机器人公司

那么站在机器人公司的角度，它的财报会变成什么样呢？
卖给数采公司的机器人记作销售收入，从数采公司买的数据记作研发费用

你要是光看它的财报会觉得：收入爆发增长、研发投入极高，妥妥是起飞中的高科技公司

但实际上它是一种循环交易：你买我的，我买你的，我们的财报都很好看

在 NVIDIA Thor 上多轮 RL 迭代后,小鸭子的体态越来越野了,像一��牛 🦆🐂 lol

你们看到的这只蛮牛冲撞鸭,它的 ONNX 推理版会开源,大家可以直接拿回去在真机上跑

同时,具身智能学习社区 https://t.co/Dg18M9ZOzt 也即将上线——上传你自己训练的 ONNX,让全世界体验你的训练成果 🚀

After multiple rounds of RL iteration on NVIDIA Thor, the little duck is getting wilder and wilder — it's basically a bull now 🦆🐂 lol

This bull-charging duck's ONNX inference version will be open-sourced, so everyone can grab it and run it on real hardware right away.

Meanwhile, the embodied AI learning community https://t.co/Dg18M9ZOzt is also launching soon — upload your own trained ONNX and let the world experience your training results 🚀

openai 还是太慷慨了，还有一次reset次数，同时跑四个项目，用不完，根本用不完

[Ethan Yeang @EthanYeang]

microduck学走路ing
终于在nvidia thor上把rl训练跑起来了

想在thor上跑强化学习解决架构兼容和驱动配置这些工程性的问题

不过咱们已经淌过一遍水了，感兴趣的小伙伴可以参考
