New tech harvests electricity out of thin air

Ambient temperature changes, which take place natively in the environment, could power Internet of Things (IoT) sensors indefinitely, say researchers.The remarkable concept, which the inventors at the Massachusetts Institute of Technology (MIT) call thermal resonating, is highly flexible — unlike previous scientific attempts at developing similar things.It essentially harvests electricity out of thin air, the group claims. No batteries or solar panel-requiring sunlight is needed.To read this article in full, please click here

Before Commenting on Someone Mentioning RFC1925 ;)

Some of my readers got annoyed when I mentioned Google’s BeyondCorp and RFC 1925 in the same sentence (to be perfectly clear, I had Rule#11 in mind). I totally understand that sentiment – reading the reactions from industry press it seems to be the best thing that happened to Enterprise IT in decades.

Let me explain in simple terms why I think it’s not such a big deal and definitely not something new, let alone revolutionary.

The Power of Women to Change the World: A message from our CEO on International Women’s Day

Today is International Women’s Day, with the goal to empower women in all settings. This year, the Internet Society is celebrating by shining a light on the women who are shaping the Internet, including our own CEO, Kathy Brown. She shared her thoughts how we can ensure that all women have a place at the table in our increasingly-connected world.

The Internet Society: Who are the women who have inspired you throughout your career? How have they inspired you?

Kathy Brown: It is sometimes seen as cliché to point to the women who raised you as your first inspiration — but for many of us, and for me, I believe it is nevertheless true that our mothers are the first fuel for our activism. My mother was a “community organizer” in the 1960’s War on Poverty in the U.S. She was an activist in rural, upstate New York — organizing communities to alleviate poverty. She was a mover and a doer; she was fearless and never yielding to powerful forces who either did not see or would not see the effects of poverty on individuals and families. Having grown up with a woman with that kind Continue reading

Riyadh, Saudi Arabia: Cloudflare Data Center #126

We are very excited to announce Cloudflare’s 126th data center in Riyadh, Saudi Arabia (only hours after launching in Reykjavík!). This joins our existing Middle East facilities to provide even stronger coverage and resilience for over 7 million Internet properties across the region.

Our newest deployment was made possible in partnership with Zain, which now experiences reduced latency for every Internet user accessing every Internet facing application using Cloudflare. At least four additional Middle East deployments are already in the works.

Riyadh, Saudi Arabia: Cloudflare Data Center #126

Over 30 million people live in Saudi Arabia, which is also the 13th largest country by area at over 830,000 square miles. In 2020, alongside the launch of entirely new “economic cities”, we might witness the opening of the world’s tallest skyscraper at a staggering 1,000m height, located in Jeddah. More modestly, but in much less than two years from now, we also expect to place a Cloudflare data center there.

Saudi Arabia has an incredibly young demographic, as over half of the population is less than 25. Additional 4G LTE deployments, while also paving the way for 5G, should drive increased Internet usage.

Stay tuned as Continue reading

Small Giants

I’m sure you’ve all come across the phrase “standing on the shoulders of giants”. Whilst it’s easy to remember or glibly repeat, it’s also easy to forget or ignore the serious message being delivered by those words. To me, the meaning is legion; something as close and personal as my parent’s care (well, of one […]

Packaging an out-of-tree module for Debian with DKMS

DKMS is a framework designed to allow individual kernel modules to be upgraded without changing the whole kernel. It is also very easy to rebuild modules as you upgrade kernels.

On Debian-like systems,1 DKMS enables the installation of various drivers, from ZFS on Linux to VirtualBox kernel modules or NVIDIA drivers. These out-of-tree modules are not distributed as binaries: once installed, they need to be compiled for your current kernel. Everything is done automatically:

# apt install zfs-dkms
