[From the last episode: We looked at how containers help to separate the different activities that might be going on at the same time within one server.] We’ve talked so far about how we can take a single program and provide better security, privacy, and proper operation by using virtualization […]

These days, there’s another concept that’s very popular in the cloud-computing world: the container. The word “container” is […]

[From the last episode: We saw some of the mistakes that can cause programs to fail and to breach security and/or privacy.] We’ve seen how having more than one program or user resident as a “tenant” in a server in the cloud can create some challenges – at least with […]

[From the last episode: We saw how pointers are an important kind of variable, representing data whose location we can’t predict in advance.] We saw last time that pointers are used to store the addresses of data stored in memory space that’s allocated while the program is running. Why might […]
