As you’ve noticed, I tend to write from time to time on my experiences with cryptocurrencies. By now you may have understood that my interest is mainly with the coins that support the equihash algorithm (ASIC resistant, GPU-based mining) such as ZCash and its derivates, ZClassic and ZenCash. The challenges
My regular readers or twitter followers may have noticed that besides data center topics, I talk about cryptocurrencies from time to time. I’ve written a beginner’s introduction about zCash mining earlier in 2017, and would now like to talk about Zencash, a very new cryptocurrency that went live on 30-May-17. The network
As you know I was invited at HPE Discover in November 2016 and at the time my vision of things for HPE wasn’t exactly idyllic. Yes, the innovations in the 3PAR line were great, but there was nothing unique going on. The Machine, a great scientific project, looked to me

With the radical transformation of the data center storage landscape, and the transition from traditional block/file storage towards software-based / software-defined solutions, plus the advent of object storage and cloud integration, the bastion of traditional storage administrators is under siege from all sides. Is there a future for the storage
Security 101: In a world that is more and more connected, where our personal data and identity are stored in many places, it’s our duty to focus on security and do our best to protect our own data – and our privacy – with the tools that are available to
Today I’m sharing my adventures with ongoing Wi-Fi issues with the Retina 13.3″ MacBook Pro (2015) and how, despite being the biggest lamer at Wi-Fi and networking you’ve ever met, I seem to have fixed the issue. I purchased my MacBook pro in early February 2016, the device has been used predominantly
Yet another career/work related post, while I seek inspiration on the next technical article. Here you go again. You’re joining a new company, you have this job you’ve dreamed of for so long, or you’ve joined the company you’ve always craved to work for. You’ve made a serious enough impression
Size doesn’t matters is not something I like to hear in my data center environment, at least when referring to virtual machines. Size indeed does matter, and what matters most is for a VM to be right-sized. This article will cover oversized VMs and proper compute resource allocation for virtual
Let’s admit it, just like some crave for the car / plane / whatever of their dreams, there’s a non negligible share of IT folks who crave to have their own home lab. With many top-notch bloggers and IT professionals having their own jaw-dropping setups, it’s sometimes hard to resist
With the news that VMware is reducing their line of vSphere offers, and the fact that they now consider vSphere as a non-strategic product, I was thinking about what the future holds for VMware. Please take this with caution, I am fully aware that vSphere is the leading hypervisor in
Friday’s vExpert announcement madness has faded, so has the weekend, and it’s time to share some thoughts on the matter. I’d like to congratulate all the new and returning vExperts.

I have casually found out today that I have been acknowledged (for the third year in a row!) with the VMware vExpert accolade, of which I am both proud and humbled. Maybe you are a returning vExpert, if so, congratulations! But if you are a new vExpert, read below (and
There are some opportunities you shouldn’t let go. Two months ago I was at a very difficult moment of my life, struggling whether I had to accept a move as Business Consultant or risk being part of an organizational layoff. No matter how hard I tried to convince myself of
