Wartungsfenster Podcast

Ausnahmsweise ein Blogpost in deutscher Sprache. Grund dafür ist, dass Claudia Kühn und ich seit Januar 2022 einen gemeinsamen Podcast rund um den Themenkomplex Datacenter, Cloud und IT ein. Eine lockere Kaminzimmerrunde in der wir entspannt über unseren Job, und alles was damit zu tun hat, plaudern.

On the road to... nowhere?

Its been four month since my last blog post, and the blog frequency was quite low before that. This blog is, to be honest, a giant pile of stuff that has not worked as expected. Okay, some random thoughts or howto’s, but most blog posts are about stuff that failed in some way. That’s a bit “depressing”. I should write more about the fun things in my life For a pretty long time my focus was on infrastructure.

What is in the bag?

Michael White published the third release of his “What is in the bag” blog post. In reference to this, I would like to share the content of my bag. I used a RIMOWA Salsa business trolley for several years. Unfortunately, it broke in June 2017 and a repair was refused by RIMOWA. I was very disappointed of the product quality and the customer service experience with RIMOWA. I decided to switch to a backpack, which felt much more comfortable than carrying or pulling the RIMOWA trolley.

Security: If it doesn't hurt, you're doing it wrong!

The Informationsverbund Berlin-Bonn (IVBB), the secure network of the german government , was breached by an unknown hacker group. Okay, a secure government network might be a worthy target for an attack, but your network not, right? Do you use the same password for multiple accounts? There were multiple massive data breaches in the past. Have you ever checked if your data were also compromised? I can recommend If you want to have some fun, scan GitHub for -—-BEGIN RSA PRIVATE KEY—–.

My tool chain for 2018

Each of us has his or her personal tool chain. Depending on your job role, the tool chain will look different. My personal tool chain does not have changed much over the last few years, but if I added or removed a tool to my tool chain, this change was often influenced by other peoples tool chain. My primary work device is a Lenovo ThinkPad X250 (Intel i5 5200U, 8 GB RAM, 250 GB SSD) with Windows 10.

Continuity vs. change

Note: I trashed this blog post several times. But I would like to express my point of view (hey, this is my blog. :D ) Some weeks back, I had an interesting discussion with a HR consultant. Bottom line: You ruin your career, if you stay for more than 3 years at the same company. IMHO this is bullshit. I have started my IT career, right after school, with an apprenticeship at a local IT company.

Fight the chaos: Design your toolbox properly

You need tools and methods to accomplish your daily tasks. No one will deny this insight. I would like to give you an insight into my box of tools and methods. These tools and methods work for me, but they do not have to work for you. The design of your personal toolbox depends on your job. Depending on who you ask, my job role consists of several roles: Currently, I am working as a consultant, head of the business unit, pre-sales consultant and technical account manager.

Why VARs should rethink their business model

Okay, the headline of this blog post is a bit provocative. This blog post is not written from the vendor perspective. It’s the perspective of someone, who’s sitting between the vendor and the customer. A value-added reseller (VAR) is typically located between vendor and customer. And the business model of a VAR is typically based on selling hardware, software and service. Added value The typical customer doesn’t have the time, money and the know-how to transform business requirements into a bill of materials (BOM).

Lean ITIL Service Operation

The IT Infrastructure Library (ITIL) is a set of pre-defined processes and common practices (I try to avoid the word “best practice” when talking about ITIL) for the IT service management (ITSM). When I talk with customers about ITIL, they often complain about the overhead of ITSM processes, that were designed according to ITIL. I already wrote about this in one of my previous blog posts (Is lean ITSM a myth?

Hey infrastructure guy, you should learn Python!

I’m not a developer. I’m an infrastructure guy. All I ever needed was to write some scripts. Therefore, I never needed more than DOS batches, BASH/ CSH/ KSH, Visual Basic Script and nowadays PowerShell. So why should I learn another programming language? One to rule them all? I don’t think that there is a single programming language that is perfect for all use cases. The spread and acceptance of a language shows a positive correlation with the number of available frameworks, tools and libraries.
