2021-08-14 15:14:36 @mbuf Hi all. This is the second talk on FOSS and companies.
2021-08-14 15:15:23 @mbuf I want to mention few important points, and you can then ask your questions.
2021-08-14 15:16:18 @mbuf This is a follow-up to an earlier discussion that we had in this channel on choosing companies
2021-08-14 15:17:19 @mbuf The first and foremost is to have a portfolio of your own where you can showcase your Free/Libre and Open Source contributions
2021-08-14 15:17:57 @mbuf This can be just your GitLab or GitHub link, or a list of patches, documentation changes, and other contributions to F/OSS projects that you have and are contributing to
2021-08-14 15:18:49 @mbuf Your work, by itself, will reflect on your calibre. Once, you have this in place, it will help attract companies who are interested in hiring you
2021-08-14 15:19:44 @mbuf By creating this portfolio of yours, you also create a name for yourself, and it helps in your branding
2021-08-14 15:20:29 @mbuf When people start noticing your work, you

2021-07-10 15:06:24 mohan43u-we the first talk is about rootless containers
2021-07-10 15:06:41 mohan43u-we lets first talk about containers
2021-07-10 15:07:07 mohan43u-we to learn containers, we need to first learn about an old command called chroot
2021-07-10 15:07:52 mohan43u-we if you read 'man chroot' you will learn how it changes the root directory of a process
2021-07-10 15:08:14 mohan43u-we every process have a root file system view (the word view is important)
2021-07-10 15:08:56 mohan43u-we normally in unix, every process see root as same

2021-06-12 15:06:43 mohan43u-we systemd-networkd is part of systemd framework
2021-06-12 15:07:01 mohan43u-we systemd is the init system in modern linux
2021-06-12 15:07:30 mohan43u-we apart from init functionality, systemd is capable of doing lot of other things in order to make a linux os usable
2021-06-12 15:07:46 mohan43u-we one of that functionality is to configure network interface
2021-06-12 15:08:16 mohan43u-we you can configure a network interface through many ways
2021-06-12 15:08:55 mohan43u-we as you see in the presenter terminal (in https://meet.ilugc.in), the command 'ip link' will show all the currently available network interfaces
2021-06-12 15:09:16 mohan43u-we there are physical interfaces as well as virtual network interfaces
2021-06-12 15:09:37 mohan43u-we you can configure a network interface either static or dynamic
2021-06-12 15:10:29 mohan43u-we as you see in the presenter terminal, I'm currently showing details about one physical network interface called eth0
