Android 检测当前网络是否可用

嵌入式设备的switch 以及PHY 芯片调试和选型 (1) 越来越的设备需要多网口的需求,于是需求搭配一个交换机实现网口的扩展。但是很多软件或是硬件工程师在实际选型和应用中经常会遇到一些问题。这里总结一下,避免大家采坑。 几个概念: MAC(介质访问控制),可以理解成数据链路层即可 PHY(物理性),简单理解层转成物理层的连接组件即可 控制接口(MDC/DMIO,I2C,... 阅读详情

 public static boolean isNetworkAvailable(Context ctx) {
  boolean bl = false;
     ConnectivityManager cm = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);  
     NetworkInfo info = cm.getActiveNetworkInfo();

利用OrthoFinder做泛基因家族聚类分析

这条命令会将 Arabidopsis_thaliana.TAIR10.59_longest_trans.pep.fa 文件中的所有序列ID,去掉ID中的空格后面的部分,只保留 > 后第一个空格之前的基因ID,并将结果保存在 An1.fasta 文件中。muscle 是一种常用的多序列比对工具,用于基因组或蛋白质序列的比对。基因家族(Gene family),是来源于同一个祖先,由一个基因通过基因重复而产生两个或更多的拷贝而构成的一组基因,它们在结构和功能上具有明显的相似性,编码相似的蛋白质产物。

汽车IVI中控开发入门及进阶(三十八):手机投屏HiCar开发

为了兼容这部分手机,车机端在向手机端发送USB控制命令字的同时,需要启动mDNS Server,广播车机端IP地址和HiCar SDK侦听的Server Socket端口(IP地址和端口在HiCar SDK初始化USB driver时,告知车机),在检测到手机断开USB连接时关闭mDNS Server。厂商在集成HiCar SDK开发HMI应用时,不可避免会使用到智能座舱的敏感权限,例如位置权限、摄像头权限、麦克风权限等,SDK初始化时,厂商HMI应用需要设置必要的车机参数供SDK使用。

多模型AI协同看K线图:从原理到最小可实现系统

大语言模型在金融图表理解中的应用正在从单模型推理走向多模型协同。其核心原理在于将同一K线图并行分发给多个大语言模型,独立输出趋势判断、关键点位与风险提示,再通过结构化解析与聚合逻辑形成综合结论。这种设计能对冲单模型视觉偏差、过度自信和风格偏置,提升分析结论的稳定性和风险表达完整性。在量化交易研究、行情日报自动生成、AI教学演示等场景中,多模型协同可作为高效的分析辅助工具。本文从工程实践角度,拆解图表预处理、模型分发、输出协议、并行调度与结果聚合的最小可运行实现,并给出生产落地时的常见问题与排查路径,帮助开发
