前段时间一直被MajdataPlay的外键输入问题困扰:有玩家反映majplay会无征兆地出现拖判和吃音,但是内屏一切正常 因为我是第一次接触游戏开发,IO这方面也完全没经验 一开始我和bb本怀疑是线程调度的问题,即:IO线程时间片被其他线程挤占了,导致IO线程无法及时处理HID设备回报。为了验证这个猜想,我们尝试提高了IO线程的优先级,照旧 接下来我怀疑是我那套框架有问题:majplay是根据上一帧与这一帧的按键状态判断按键是不是"click"。为此我重写了这部分的实现,改进了IO线程与主线程之间的交互,问题照旧....... 到这里我已经怀疑这不是majplay的锅:IO线程没有任何异常,IO线程与主线程的交互没有问题,Note判定逻辑也没有问题,那就是设备确实没有回报给majplay或者设备发过来的回报中按键确实没有按下,但是大佬说hdd没有这种问题.....(人已经快崩溃了,这完全看不透也摸不着,因为我用单片机模拟玩家打高速纵连是完全没有问题的,我在家里用手台测试也没有问题) 到最后,bb本灵光一闪,说有没有可能是led刷新率过高,把按键控制板干爆炸了?我们让大佬把led刷新间隔从16ms改成100ms,吃音问题瞬间没有了,无语了 。。。。。。。。。。。。。。。。。。。。 adx是一个控制板同时管理按键和led,为什么我没有遇到吃音问题呢,因为我的手台不是adx的... #dev

Repost of the publication 🇨🇳Hydrogen notes from China: hydrogen is everywhere #H2nomics#international A final travel note from Igor Chausov and Pavel Melnikov from China — on the role of hydrogen in the country’s energy strategy. 🚌 At a bus stop on the outskirts of Shanghai, a bus with green plates and the words “Fuel Cell” on its side pulls up as part of everyday routine, passengers getting on and off. We observed this not only in megacities but also in many county-level cities across China: hydrogen buses, together with the more widespread electric buses, have largely displaced diesel vehicles. 🚜Beyond buses, a wide range of hydrogen-powered equipment is already operating — either in pilot mode or commercially — on Chinese roads: trucks and trailers mining dump trucks bulldozers water trucks street sweepers garbage trucks warehouse forklifts shunting locomotives 👉 This diversity is supported by the rapid development of hydrogen fuel cells and the expansion of industrial-scale production of these next-generation power systems. 🔌Hydrogen is also used in stationary applications: power supply for remote mining and infrastructure sites autonomous ultra-fast EV charging hubs telecom infrastructure off-grid settlements 🏭 While the chemical industry still largely supplies “grey” hydrogen to transport and other sectors, it is simultaneously launching numerous projects to switch from coal and scarce natural gas to green hydrogen — with expectations of cost reductions driven by cheaper renewables and electrolyzers. 🎯Key takeaway China’s energy strategy avoids binary choices and instead follows a “middle path” (中道, Zhong Dao). 👉 It does not choose between electrification and hydrogen. Instead, it treats hydrogen: as a tool for electrifying industry and transport and as a bridge between the world of “molecules” (chemicals, fuels) and the world of “electrons” (powering transport, industry, and utilities) 📌Bottom line: In China, hydrogen is not an alternative to electrification — it is an integral part of a broader, system-level energy transition.
