IBM says buying Red Hat makes it the biggest in hybrid cloud

In a move that IBM says will make it the world’s leader in hybrid cloud, the company says it’s going to buy open-source giant Red Hat for $34 billion, banking on what it sees as Red Hat’s potential to become the operating system of choice for cloud providers.IBM says it expects growth in the use of cloud services to blossom in the coming years, with enterprises poised to expand from using cloud for inexpensive compute power to placing more applications in the cloud.[ Now see After virtualization and cloud, what's left on premises?] “To accomplish this, businesses need an open, hybrid cloud approach to developing, running and deploying applications in a multi-cloud environment,” IBM says in a written statement.To read this article in full, please click here

Network documentation 101 ! How? When? Why?

Documentation is an extremely important rule when building a network. You will know what has been done in your network. With a good network documentation, the network support and maintenance procedures could handle the incidents in a more professional and organized way.     Without a good network documentation, there is no map, topology or …

HiDPI on dual 4K monitors with Linux

I am using a Lenovo Thinkpad X1 Carbon laptop (210 DPI) since four years and a Nokia 8 phone (550 DPI) since a year. I enjoy their HiDPI screens: text is crisp and easy to read. To get a similar experience for my workstation, I bought a pair of Dell P2415Q monitors:

Two Dell P2415Q
Dual screen setup with two Dell P2415Q monitors

Monitors

The Dell P2415Q is a 24” display featuring an IPS panel with a 3840×2160 resolution (185 DPI) and a complete coverage of the sRGB color space. It was released in 2015 and its price is now below $400. It received positive reviews.

One of my units arrived with a dead pixel. I thought it was a problem from the past but Dell policy on dead pixels says:

During LCD manufacturing process, it is not uncommon for one or more sub-pixels to become fixed in an unchanging state. A display with a 1 to 5 fixed sub-pixel is considered normal and within industry standards.

Another issue is the presence of faint horizontal grey lines, (barely) visible on white background. The issue seems to not be uncommon but Dell is dismissive about it. If I sit correctly, the Continue reading

The 2018 Africa Summit on Women and Girls in Technology: My Story

October 9-11, 2018 will remain etched in the memories of the more than 250 girls and women in technology who converged in Accra, Ghana to participate in the second Africa Summit on Girls and Women in Technology. I was privileged to participate in this summit as well – together with seven other women in technology from my community in Ghana.

Highlights

The delegates were invited to provide their input into discussions on ongoing key policy processes in the continent and across the globe on broadband Internet access, sustainable development, and women’s empowerment.

The Deputy Minister of Communication from Ghana, Vincent Sowah Odotei, made the opening address, where he detailed Ghana’s achievements and plans to digitize Ghana and to support women to participate as users and producers of technology.

The program was planned such that the morning to lunchtime sessions were interactive keynote panels and “fireside chats,” touching on the following themes: Leadership in Technology Policy; Policy Engagement: The What, Why, and How; Women Advancing Science, Technology, Engineering, Arts, Mathematics and Design (STEAMD); Institutional Support for Women in Tech; and other topics.

The workshops were: Community Networks, Wikipedia Edit-a-thon, Enhancing Digital Security and Advocacy, and Mobilizing for Impact Continue reading
