Observability Is the New Black

In early October I had a chat with Dinesh Dutt discussing the outline of the webinar he’ll do in November. A few days later Fastly published a blog post on almost exactly the same topic. Coincidence? Probably… but it does seem like observability is the next emerging buzzword, and Dinesh will try to put it into perspective answering these questions:

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:

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

By now pretty much all of online advertising is adtech, which doesn’t sponsor publishers. Instead it uses publishers to mark and track eyeballs wherever they might go. It does that by planting tracking beacons (mixed like poison blueberries into those cookies sites now require “consent” to) on readers’ browsers or phones, and then shoots the readers’ eyeballs with ads when they show up elsewhere on the Web, preferably on the cheapest possible site, so those eyeballs can be hit as often as possible within the budget the advertiser has paid adtech intermediaries. @Doc Serls Weblog

Consider, then, that most useful work relies on TCP/IP, which itself relies on the Domain Name System (DNS). We should know as much as possible about our use of the DNS, but most IT administrators are much too busy learning their specialized craft to also become experts on every enabling technology. —Paul Vixie @Dark Reading

The technology products that drive today’s businesses are increasingly produced through a highly diversified and complex international supply chain. Whether it is standard networking gear or a more specialized device like a human-machine interface or remote terminal unit, equipment is often developed through an elaborate web of OEMs, chip makers, 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

More Ansible Modules for Extreme

We published Ansible modules for Extreme SLX devices earlier this year. Now we have modules covering all the main Extreme Switching & Routing product families - SLX, VDX, MLX, EXOS, VSP.

Available Modules

• SLX - slxos_command, slxos_config, slxos_facts, slxos_interface, slxos_l2_interface, slxos_l3_interface, slxos_linkagg, slxos_lldp, slxos_vlan
• VDX - nos_command, nos_config, nos_facts
• EXOS - exos_command, exos_config, exos_facts
• VOSS - voss_command, voss_config, voss_facts
• MLX - ironware_command, ironware_config, ironware_facts

All modules are available in the current GA version of Ansible (2.7), except for voss_config. That one proved a bit trickier for me to write, and I didn’t get it done in time for the 2.7 cutoff. That one is an open Pull Request against the Ansible devel branch. That should get reviewed and merged soon. It will then make its way into the next GA release. You can of course use the code direct from my branch in the meantime.

All modules use the network_cli plugin. See Platform Options for general information about how to use this connection type.
