Let's Talk About Tech!

Background I think, like most of the 3D Printer guys, you have your printer in your basement. This is indeed a great place, but it means each time you are about to start a print, you have to go downstairs, start the power switch, and go back at your computer place and star the print. OctoPrint is easy to get remote access to the printer, but, what about controlling the power switch ?!?

Background We came to a point where unprotected VMs can be out of sight and we could potentially miss protection on some important object. We do not want to apply a default protection at the top level of our infrastructure to avoid any uncomfortable storage usage. So what ? It would be nice to have a script running on a cluster and check what are the unprotected VM and apply an SLA ... mmmh let me think...

Background I would like to automate the Nutanix AHV cluster addition on my Rubrik appliances. Either for testing purpose or for more general deployments. In order to achieve this, you need to perform couple of actions and clicks in the UI. But since the Rubrik UI is API-First, of course, that should be doable via API call ? Isn't it ? But why limiting this to only adding new Cluster ? Let's see...

Background Would it be nice to directly manipulate Google Drive as part of the OS File System ? Would it be nice to automate backups directly in the cloud ? Would it be nice to stop buying expensive external storage ? The idea is not to send a "all to cloud" message. But sometimes, this very handy to have quickly have access to some centralized storage. Well, I think so. But How ? Cloud Storage is object storage (S3 like), so each files are actually identified by a unique URL and a set of credentials granting or not certain rights. There is a way of course !

Background Sending REST API calls to the cluster is sometimes slow and not very efficient. I came across some interesting posts on that topic. It looks like while REST is getting all the results (even the one you are not interested with) it exist another query type that only returns what you are looking for. This is GraphQL. Let's have a look !

Background Yeah, I know, I should have written it down in a safe place, in a vault or so. But it happened. I've lost access to my Raspberry taking care of my hotspot and sending my various API calls to my Yamaha Amplifier . This is an issue since I need to adjust some settings !

Background Lock down, working from home, ... we all been there and for a long time. Since this situation is going to last; we need to have a nice working environment. Today, I'm presenting you a nice way to decorate your home office and ... yes, discount code will follow !

Background There is no mystery, java log4j flaw had a huge impact on any IT team these days. If you want to know more details about it, I really encourage you to read this and upgrade asap your affected systems. This being said, it would be nice to know what systems are affected ... It could be cumbersome to search in each and every systems, especially if you have more than 1000 VMs ... If you are using Rubrik for your backups, it might simplify things !

Background We have a quite large AHV infrastructure and sometimes this is not always easy to get all the relevant details to improve/maintain it. Don't get me wrong, Prism Central is helping a lot. But, when it comes to optimisation of the assets, it is hard to see what gains we can make - starting by detecting the powered off VMs.

Background When we had an issue on an AHV VM, the first reflex was to restore it from last night backup. It was very quick and we were all happy ... unless we realized that no networking was connected. We opened a case with Nutanix to troubleshoot the issue and ....
