A few weeks ago I had to do a script to migrate all of a company’s CV data to another system via means of a database dump and hammering this data down an API. I was excited to get coding again, and as it usually goes with excitement, it was crushed by reality within mere 15 minutes as my Python development environment came to halt. http://vepsalainen.eu/posts/7_simple_infra_monitoring/ Sun, 23 Aug 2020 10:10:49 +0300 http://vepsalainen.eu/posts/7_simple_infra_monitoring/ Intro My home network is getting populated with various Raspberry Pis doing mundane tasks, and at some point I wanted a nice view on how everything is doing. Also updating those machines is currently more or less a manual task, so in order to automate stuff, I need a view on how they are doing (in case some update would fail). Enter: Monitoring. There is a problem though; majority of the solutions around are do-it-all-and-beyond solutions where I needed a really-really-simple one. http://vepsalainen.eu/posts/6_mounting_nuc_to_dell_monitor/ Fri, 24 Jul 2020 10:00:49 +0300 http://vepsalainen.eu/posts/6_mounting_nuc_to_dell_monitor/ Dell monitors, amongst others, have Quick VESA Mounts. Handy for just plugging your monitor to it’s stand, but the implementation is not good for anyone wanting to mount stuff on their monitor. As you can see from the pictures, the mount hides the actual VESA mounts, without actually utlizing them in any way. The plastic cover can be removed, exposing VESA mounts, but this makes the mount loose. So we won’t do that. http://vepsalainen.eu/posts/5_implementing_containerized_pihole/ Tue, 21 Jul 2020 20:19:49 +0300 http://vepsalainen.eu/posts/5_implementing_containerized_pihole/ Intro Pretty much everyone, who is tech inclined, blocks their ads nowadays. But what if you could block all the ads on all the browsers on your whole internal network? Including those pesky mobile phones? Enter: pi-hole! Pi-hole works as a DNS server, blocking all pesky DNS queries to URLs that smell like advertisements. With the containerized version of pi-hole you are not only restricted to RPis, but you can run the setup just about everywhere you can run a container in. http://vepsalainen.eu/posts/4_coping_with_windows10/ Fri, 10 Jul 2020 07:10:49 +0300 http://vepsalainen.eu/posts/4_coping_with_windows10/ Intro For a while my home computer (a NUC) has had Ubuntu on it and my work machine has been a Macbook Pro. As it’s summer holidays, and I sometimes find myself idle with funny thoughts, I decided to clean Ubuntu off my NUC and go full Windows 10. In this blog post I give out some hints how to cope with to make the best of this operating system really popular amongst ATMs and elderly people. http://vepsalainen.eu/posts/3_securing_identity/ Wed, 17 Jun 2020 17:20:49 +0300 http://vepsalainen.eu/posts/3_securing_identity/ Passwords originate from ancient times (like tech generally) with military context. They are used to confirm that the you are person you are claiming to be, as only you know the secret. “Halt, who goes there” “It is me, Romulus” “What is the password?" “Ananas!" “Proceed!” When you think of it, doing authentication this way still in 2020 seems rather silly. Nevertheless, as the world and it’s services are getting digitalised, an essential part of securing your digital identity is securing your passwords. http://vepsalainen.eu/posts/2_azure_terratest/ Wed, 10 Jun 2020 07:10:49 +0300 http://vepsalainen.eu/posts/2_azure_terratest/ Intro I recently had the opportunity to find a solution on automatic testing for Terraform-made infrastructure on Azure on a project I was working on. The project’s setup was the following: Microsoft Azure, as a cloud platform Azure Repos, for version control Azure Pipelines (configured with yaml), for CICD Terraform, for IaC After consulting Mr. Goole on what tools would be the best for testing the infra we were left with two candidates: Chef Inspec and Terratest. http://vepsalainen.eu/posts/1_career_advice/ Fri, 29 May 2020 20:47:49 +0300 http://vepsalainen.eu/posts/1_career_advice/ I was recently approached by a person via Linkedin, asking for some career advice on moving into a “more tech oriented” position. This person had read some of my earlier blog posts on gaining cloud certifications and was looking for an answer more tailored to her needs and something that would be updated to the state of 2020. I spent the better half of my day mentally drafting my response, but my processing of the issue didn’t stop after I pushed the “send”-button. http://vepsalainen.eu/about/ Tue, 26 May 2020 18:02:10 +0300 http://vepsalainen.eu/about/ I’m Tero Vepsäläinen and this is a blog for my (mostly) career oriented bloggings / musings. I work as a DevOps Lead for Polar Squad combining softer skills as a Site Lead and dipping into the hard(core) skills as a DevOps Consultant. To contact me, use Linkedin. Not the bestest of platforms, but I guess pretty much everyone has an account there and I don’t have to figure out how to make my e-mail address spam-bot-proof.
