Measure code review performance across GitHub teams with leaderboards and reviewer analytics.
u/SnooStrawberries827 · Reddit
my team had 47 open PRs and nobody was reviewing them, so I gamified it our team hit 47 open PRs at one point last month and nobody was reviewing them. tried slack reminders, deadlines, rotating reviewers, none of it really stuck. might be related to the fact that everyone's hyped about how fast AI can write code now, copilot cranking out entire features in hours, but none of that matters if the PR just sits there for a week. feels like writing code stopped being the bottleneck a while back

Benchmark AI models by having them animate a 3D banana plant's full lifecycle.
fran-mora · HN
I gave 5 AI coding agents one prompt: grow a banana plant through its whole life in three.js: sprout, leaves, flower, fruit, rot, then pups that restart the loop. It's deceptively simple and yet very hard to get right from procedural code: you have to write working three.js and understand how the plant is actually built; how it hangs, ages and decays. Get the biology wrong and the code renders something weird. These are agents, not bare models (Claude Code and Codex for now). They can use tools, including playwright to check their work and improve it.

最近玩《黑悟空》时觉得手柄灵敏度有点问题,于是做了个手柄在线检测工具 最近在玩黑悟空时,有时候感觉视角转动不太顺,摇杆回中也有点奇怪。 一开始我不确定到底是游戏里的灵敏度设置、蓝牙连接,还是手柄本身有轻微漂移,所以就找了一些在线手柄检测工具。虽然能用,但有些界面比较乱,有些只能显示简单的按键状态,对死区和轮询率的解释也不太清楚。 于是干脆自己做了一个: 欢迎体验,如果遇到问题,我可以立即修复: https://gamepadbench.com/ 目前可以检测: - 左右摇杆位置和回中漂移 - 按键与模拟扳机输入 - 自定义死区范围 - 浏览器观察到的轮询率 - 浏览器和手柄支持时测试震动 我自己目前主要用 Xbox Series S 手柄通过蓝牙测试,摇杆、按键、扳机和震动都能正常识别。Chrome 和 Edge 的兼容性相对更好,连接后需要先按一下手柄上的任意按键,让浏览器识别设备。 现在比较想收集不同设备的兼容性反馈。如果大家手边有 Xbox 、PS5 、Switch Pro 或其他第三方手柄,可以帮忙试一下。 如果
