LUKI NOTES

Today, many systems may generate huge amounts of data such as system logs, financial transactions, customer profiles, security incidents, and so on. It is encouraged by the advancement of some technologies like IoT, mobile devices, and cloud computing. There are also fields that specifically learn to manage and process a lot of data like data science and machine learning. A set of data can be processed to produce certain results like detecting anomalies, predicting the future, or describing the state of a system. To generate such a result, the typical phases are collecting data, data preparation, visualization, and data analysis or generating results. In collecting data, we have to take some considerations including the location where the data will be stored, the type of stored data, and the retrieval method or how other systems can consume the data. When we want to select a location, we should consider whether the storage is available in the cloud or on-premise infrastructure, ...

We may utilize different keys for different projects or accounts. When we pull data from a Git repository through an SSH connection, by default the Git tool will follow the default SSH configuration for selecting the key used which is located in ~/.ssh/id_rsa . We can also set a custom SSH configuration located in the  ~/.ssh/config  file that will be followed by the Git tool too as explained in my other post . For setting the private key locally or per session, there are other options. First, we can utilize an environment variable that will be read by the Git tool for selecting the correct SSH command which is GIT_SSH_COMMAND . The usage is as follows. GIT_SSH_COMMAND="ssh -i ~/.ssh/your_id_rsa -F /dev/null" git clone git@github.com:your/project.git The -F /dev/null parameter is used for ignoring any available SSH configuration in the host. This method will apply the custom SSH command during the user session or it can be permanent too by setting it in the host envi...
