My First Grace Hopper Celebration

My First Grace Hopper Celebration

Cloudflare #GHC18 team

I am 25+ years into my career in technology, and this was the very first time I attended a conference geared towards women.

A couple of weeks ago I went to Grace Hopper Celebration (#GHC18), and I can still feel the exuberant energy from the 22,000 women over the intensive 3 day conference. I attended with our Cloudflare team; our purpose was to connect with women in the greater tech community and recruit new talent to join our team and mission to help build a better Internet.

Cloudflare prioritizes GHC because we recognize that diversity in our company, and particularly in our technical departments, is crucial to our success. We believe that the best companies are diverse companies. This was Cloudflare’s second time sponsoring GHC, and I was part of the planning committee. This year I headed to the event with 20 of my colleagues to meet all of the incredible attendees, hold on-site interviews, and even host our own Cloudflare panel and luncheon.

Getting to #GHC18

Early Tuesday morning, the day before the conference, as I joined the Southwest Airlines boarding line at Oakland Airport, my fellow passengers were not the usual contingent of Continue reading

Wave energy to power undersea data centers

Offshore, underwater data centers are going to be powered using wave motion, says a sustainable energy developer. And it's going to happen soon.Commercial wave energy company Ocean Energy says it’s almost completed a marine hydrokinetic wave generator build and that the 1.25 Megawatt power-production capacity vessel will be ready to deploy in 2019.The 125-feet-long wave converter OE Buoy will provide enough electricity for a subsea data center platform, the company claims.“Technology companies will be able to benefit from wave power [in] marine-based data storage and processing centers,” Ocean Energy CEO John McCarthy said in a press release earlier this month. “OE Buoy presents them with the potential double-benefit of ocean cooling and ocean energy in the one device.”To read this article in full, please click here

GLIF 2018 Held at the Home of Hamlet

The 18th Annual Global LambaGrid Workshop (GLIF 2018) was held on 18-21 September 2018 at the Kulturværftet in Helsingør (Elsinore), Denmark. Kronberg Castle, located next to the venue, was immortalised as Elsinore in the William Shakespeare play Hamlet, but there proved to be nothing rotten with the state of high-bandwidth networking as 50 participants from 19 countries came to hear how these networks are facilitating exascale computing in support of biological, medical, physics, energy production and environmental research, and to discuss the latest infrastructure developments.

This event was organised by myself with support from NORDUnet who hosted the event in conjunction with the 30th NORDUnet Conference (NDN18), and where I also took the opportunity to raise awareness of the MANRS initiative.

The keynote was provided by Steven Newhouse (EBI) who presented the ELIXIR Compute Platform which was being used for analysing life science data. In common with high-energy physics, genomics research produces a lot of data, but this is more complex and variable, requires sequencing and imqging on shorter timescales, and of course has privacy issues. The European Molecular Biology Laboratory is based across six countries and employs over 1,600 people, but also collaborates with thousands of other scientists Continue reading

A Question of Timing

When considering website performance, the term TTFB - time to first byte - crops up regularly. Often we see measurements from cURL and Chrome, and this article will show what timings those tools can produce, including time to first byte, and discuss whether this is the measurement you are really looking for.

Timing with cURL

cURL is an excellent tool for debugging web requests, and it includes the ability to take timing measurements. Let’s take an example website www.zasag.mn (the Mongolian government), and measure how long a request to its home page takes:

First configure the output format for cURL in ~/.curlrc:

$ cat .curlrc
-w "dnslookup: %{time_namelookup} | connect: %{time_connect} | appconnect: %{time_appconnect} | pretransfer: %{time_pretransfer} | starttransfer: %{time_starttransfer} | total: %{time_total} | size: %{size_download}\n"

Now connect to the site dropping the output (-o /dev/null) since we’re only interested in the timing:

$ curl -so /dev/null https://www.zasag.mn
dnslookup: 1.510 | connect: 1.757 | appconnect: 2.256 | pretransfer: 2.259 | 
starttransfer: 2.506 | total: 3.001 | size: 53107

These timings are in seconds. Depending on your version of cURL, you may Continue reading

MUST READ: Operational Security Considerations for IPv6 Networks

A team of IPv6 security experts I highly respect (including my good friends Enno Rey, Eric Vyncke and Merike Kaeo) put together a lengthy document describing security considerations for IPv6 networks. The document is a 35-page overview of things you should know about IPv6 security, listing over a hundred relevant RFCs and other references.

No wonder enterprise IPv6 adoption is so slow – we managed to make a total mess.
