我们知道无绿幕抠像（也叫智能抠像、轻松抠像）是由计算机通过对人物的轮廓识别来进行的，前些日子给大家介绍了英伟达NVIDIA的一个带有无绿幕抠像的软件Broadcast，无绿幕抠像效果还不错，但是这个软件的运行，需要英伟达NVIDIA GeForce RTX™2060 和以上级别的
从win10直接跳到win11系统，用了一段时间，页面清爽，类手机使用习惯，总体满意，个别使用习惯上、设置上需要学习和熟悉下，同时win11也确实砍掉了一些功能，比如右键没有新建txt文档 ，有点让人费解~ 相信很多人都习惯用txt临时记点东西，今天教大家把这个功能恢复出来。
MLPerf在测试时使用了Llama2-7B_INT4模型，总体来说对硬件的要求并不算高，First token时间不到1秒，平均速度为12.91 tokens/s，因此酷睿Ultra 5 225H平台部署本地化AI是基本没有性能方面的问题的。
BIOS设置为全英文界面加上专业名词不容易理解所以部分小伙伴一到BIOS设置界面就非常头疼今天暖心的小微帮大家整理了BIOS的中英文对照表以后进入BIOS界面再也不怕看不懂啦！温馨提示：BIOS设置界面根据产品型号不同会有所区别，今天我们以ThinkPad X390为例。
不久微软也公布了相关内容 ，其中关于默认值的部分值得关注:Recommended Defaults for Enabling/Disabling Virtualization Extensions. The default setting of this switch requires some thought. Consider the costs of disabling Intel Virtualization Technology/AMD Virtualization through a system firmware setting: If these facilities are disabled by default in system firmware， users would have to explicitly enable that support on each platform instance for legitimate uses， which would represent a significant challenge for enterprises that have thousands of machines and plan on using the hardware extensions. The cost of enabling virtualization hardware support through a manual system firmware setting would result in an increase in deployment time and cost. This cost can be mitigated through the use of various in-band and out-of-band mechanisms for remote management. Given the current usage model for the virtualization extensions， we believe that the following default settings are the right ones for system firmware: For systems that are destined for a server role ， enable the virtualization extensions. The threat of running malicious code as an administrator on servers is reduced through Windows Server policies and organizational best practices. For systems that are destined for a client role， disable the virtualization extensions. For systems that might be deployed in either a server or client role ， it would be prudent to disable the extensions by default. As always， the exception to any guideline is when a customer specifically indicates to a manufacturer that they do not want to follow that guideline.
