AWS reserved instances limit exceeded Problem Cause and Solution

This alert usually occurs when you choose the “no prepayment” reserved instance program. The reason for this is that you don’t have enough credit, in other words, your monthly expenses are too low. In this case, it’s best to choose a partial or full prepayment plan, so you can pass. Moreover, the partial prepayment and full prepayment programs will be more cost-effective. You can save a lot of money if you buy for a long number of years.

Solve the problem of timeout and slow installation of yarn packages such as electron and chromedriver

Installing electron and chromedriver with yarn in China is often a problem that cannot be connected. At this time, we may prefer to use a mirror repository in China to speed up the process, rather than setting up a proxy. And when installing electron, it is useless to set yarn’s global proxy alone. So how do you set up proxies based on different packages? You can follow the sample commands provided in the list below to set it up.   yarn global settings Set the repository address used by yarn to install general packages. yarn config set registry 注册模块镜像 yarn config set disturl # node-gyp 编译依赖的 node 源码镜像 This is the result of running the above command, and you can clearly see if the setup was … Read more

Implementation of a Hybrid Simulated Annealing Algorithm for Solving the Three-Dimensional Boxing Problem MATLAB

As I need to solve a three-dimensional packing problem in mathematical modeling, I have selected the paper “Hybrid Simulated Annealing Algorithm for Solving Three-Dimensional Packing Problems” published by Prof. Zhang Defu et al. in the Journal of Computing as the theoretical basis of the problem after searching. The abstract of the paper is as follows: A hybrid simulated annealing algorithm for efficiently solving the Three Dimensional Container Loading Problem 3D-CLP is proposed . The Three Dimensional Container Loading Problem (3D-CLP) requires loading a subset of a given set of boxes into a container such that the total volume of the loaded boxes is maximized. The hybrid simulated annealing algorithm presented in this paper is based on three important algorithms: (1) the composite block generation algorithm, which differs from … Read more

Solve the problem of oh-my-zsh plugin ‘zsh-autosuggestions’ not found and plugin ‘zsh-syntax-highlighting’ not found

When installing the zsh plugin zsh-autosuggestions or zsh-syntax-highlighting, we generally encounter the problem of oh-my-zsh plugin ‘xxx’ not found. Now, we analyze and solve the oh-my-zsh plugin ‘zsh-autosuggestions’ not found and plugin ‘zsh-syntax-highlighting’ not found problems. The reason for the problem is that the code repository of the plug-in has not been cloned to the local location, so the plug-in you want is not actually installed. Solving the problem is very simple, just simply enter the following command: $ git clone ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions $ git clone ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting $ source ~/.zshrc You can then reopen the shell and find that the problem is resolved. You can also use this method to solve such problems with other plugins.

Resize hard drive partitions with Gparted Live ISO bootable images

Introduction I have an 8G TF card with Openwrt installed on it, and the capacity of the root partition is not enough to meet my usage needs. So I started to expand the size of the root partition. The file system format of the root partition is Ext4. First, I tried to use DiskGenius and other Windows tools to expand the capacity, but unfortunately, none of them worked. So, we are going to use Gparted to expand it. Since the tool needs to run in a Linux environment, I didn’t really want to install a Linux distribution virtual machine for this purpose, so I used Gparted’s lightweight ISO image with Virtual Box virtual machine. Preparation First download and install the VritualBox virtual machine and VM VirtualBox Extension Pack. … Read more
