3 Things I Learned - Week #8

All in all this has been a good week – some ups, some downs – but knowledge is a never ending journey.

Here are some of the things I learned about over the last few days.

  1. Randy Bias wrote a very interesting point about how risky it can be to ‘check’ your into a CI/CD pipeline. Continuous Delusion at the Infrastructure Layer is a good read at understanding thta not everything belongs in the pipeline – you should consider how big your blast radius is.
  2. I am currently doing a Ambulance drivers course (that is the subject for a whole different post) but I never knew that there three different kinds of Hepatitis – where Hepatitis C – is the worst – and there is no cure known today.
  3. I did not even know that there were such large numbers Nine quintillion (9,223,372,036,854,775,808). Announcing the first SHA1 collision discovered this week by Google. I know that this is really nerdy – but still a good read.


3 Things I Learned - Week #7

A week where our Prime Minister Benyamin Netanyahu went to visit President Trump in the U.S. will always be an interesting one – no matter how you look at it.

Here are some things that enriched my knowledge this week.

  1. One of the things that someone told me regarding AWS and IAM roles attached to a instance – was that you only have a single chance of assigning a role, and once you do it, that’s it – no going back.
    So it seems that this is not the case. Attach an AWS IAM Role to an Existing Amazon EC2 Instance by Using the AWS CLI will show you the light and how to change a role after an instance has been provisioned.

  2. S3 is a great webserver – specifically if all you need to do is serve files. One such a repository that fits the bill perfectly – is a yum repo. There are hundreds of ways to do this, but this is the only one that I could find that would allow you to create a yum repo with multiple versions (with minor differences between them) – without having to duplicate the packages for each and every version.

  3. Never underestimate the powers of Social Networking. And of course – there are just some people who are just willing to sit down and have a conversation about technology. One such person is Kelsey Hightower. Thank you!
