I understand modern computers have modified Harvard architectures. Can the fact that they can read instructions from somewhere other than where they hold data allow them to fetch instructions directly from ROM chips? Do they load the BIOS to RAM first, or do they execute it directly from the chip? I don't have a computer I can open nearby, so... If I remove ALL the RAM from the memory slots, will the computer be able to start the full BIOS, run the POST stuff and tell me I need RAM? It's funny I've never tried it... EDIT: my intention with this question is to learn whether commercial CPUs (or

Obviously, I can load yaml directly, but was wondering if there's something

在Ubuntu下安装docker不会遇到什么问题，但是centos6却会遇到一些问题，但是总结起来也无非两点：内核和依赖 1）升级内核 centos6.5下的内核是2.6，但是docker要求的是3.10以上，所以需要升级内核 [smartlife@iZ28xflbekqZ ~]$ uname -r 2.6.32-573.26.1.el6.x86_64 升级（yum方式） 1、导入public key rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org 2、安装elrepo到内核为2.6.32的CentOS中 rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm 3、安装kernel-lt(long term support)长期支持版本 yum --enablerepo=elrepo-kernel install kernel-lt -y 4、编辑grub.conf文件，修改Grub引导顺序 vim /etc/grub.conf 确认安装的新内核的位置，将default的值调整为新内核的顺序，一般新安装的内核在第一个位置，如本次升级案例中新装的内核位置为0，所以将default修改为0，保存退出，reboot重启服务器

概述 对于 Spring 和 SpringBoot 到底有什么区别，我听到了很多答案，刚开始迈入学习 SpringBoot 的我当时也是一头雾水，随着经验的积累、我慢慢理解了这两个框架到底有什么区别，我相信对于用了 SpringBoot 很久的开发人员来说，有绝大部分还不是很理解 SpringBoot 到底和 Spring 有什么区别，看完文章中的比较，或许你有了不同的答案和看法！ 什么是Spring呢？ 先来聊一聊 Spring 作为 Java 开发人员，大家都Spring可不陌生，简而言之， Spring 框架为开发 Java 应用程序提供了全面的基础架构支持。它包含一些很好的功能，如依赖注入和开箱即用的模块，如： Spring JDBC 、 Spring MVC 、 Spring Security 、 Spring AOP 、 Spring ORM 、 Spring Test 这些模块大家应该都用过吧，这些模块缩短应用程序的开发时间，提高了应用开发的效率 例如，在 Java Web 开发的早期阶段，我们需要编写大量的代码来将记录插入到数据源中。但是通过使用 Spring JDBC 模块的 JDBCTemplate ，我们可以将这操作简化为只需配置几行代码。 什么是Spring Boot呢？ Spring Boot 基本上是 Spring 框架的扩展，它消除了设置 Spring

Apparently the app is started after the boot but it immediately crashes (just to be clear the app normally works fine). I have already read and tried different solutions ( link1 , link2 ) and actually the same code works fine with another app I was developing.
