A few weeks ago I had the opportunity to be briefed by the folks at Liqid, a Colorado-based startup. Their website claims that “The future is on-demand composable infrastructure”. There are now several companies claiming that they operate in this space, so we set to understand what is Liqid vision
I recently had the opportunity to attend a technology briefing from Uila, a company that works in the IT Monitoring space. This is a briefing I took up with great interest since colleagues and friends in the community had been talking (and writing) highly of them after they had presented
I’ve been writing twice about Zencash in 2017, first to introduce the project, then to talk about improvements made in the course of 2017. As we enter 2018 and the project has a solid record of achievements, it would be good to review what was done in 2017 and what
I’ve put together this guide to help the many people who reach out to me and ask me if it’s worth to invest in cryptocurrencies and if so, how to proceed and what to invest into. Because I keep repeating the same stuff over and over, and because the topic
Today Ravello announced that their nested virtualization solution, widely known and acclaimed by VMware technologists, is now available as a bare metal service on Oracle Cloud. What does this announcement exactly means, and beyond technological aspects what are the benefits of this solution? My regular readers may know about Ravello
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
Note: this article has been updated on 19-Apr-17. zCash is a new decentralised digital cryptocurrency which aims to provide better privacy of transactions by allowing either transparent addresses (t-addresses) or zero-knowledge proof addresses (z-addresses). While it uses a part of BitCoin’s original code, it’s been heavily modified by the development team. zCash
The more I’ve been working in IT, the more I’ve seen security disasters and the more I’ve become self-conscious about privacy and security. One of the largest pieces of our digital presence are our e-mail addresses. I’ve wanted to secure my e-mails and my privacy for a long time but the hassle of going
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
