甲骨文考虑将 Java EE 送给开源基金会
甲骨文想要结束它在 Java 平台企业版 Java EE 上的主导开发角色，寻找开源基金会接手。甲骨文称，即将发布的 Java EE 8 提供了一个机会重新思考 Java 的开发。虽然目前 Java 的开发是在开源社区的参与下进行的，但甲骨文主导的开发流程被认为并不敏捷，灵活或足够开放。甲骨文认为让开源基金会接手可以采用更敏捷的开发流程，更灵活的许可授权和改变治理流程。甲骨文同时表示，它会继续参与 Java EE 的开发。Red Hat 和 Eclipse 基金会都对此表示欢迎，认为转移到一个供应商中立的开源基金会对平台和社区都有益。Eclipse 基金会表示愿意接手。

咸鱼了又没有PV成...原因我就不说了,现在我把之前欠生存战争吧的几行代码写了就去玩游戏..玩腻了就去把ls的server写了.,还要搞开发板...🙈

估计彻底结束放假前ls还能发布第一个版本,如果能再做到#![no_std],使用libc来进行文件IO的话就可以做PV了,不然算了

这时候我发现snowman给出的反编译结果🌚
int64_t printf = 0;
int32_t fun_510(int64_t rdi) {
goto printf;
}
int64_t c_print() {
int32_t eax1;
int64_t rax2;
eax1 = fun_510(12);
*reinterpret_cast<int32_t*\>\(&rax2) = eax1;
*reinterpret_cast<int32_t*\>\(reinterpret_cast<int64_t\>\(&rax2) + 4) = 0;
return rax2;
}
虽然垃圾的不知道到那里去了,但的确比反汇编的好...
