1/3: Very happy that LOCO, the International #Workshop on #Low #Carbon #Computing we started two years ago, is going to take place again! Adrian Friday and team will host #LOCO2026 in Lancaster and online on September 10 and 11 this year! 💻 🌱 lancaster-university.github.io/loco2026/

Key info as displayed on https://lancaster-university.github.io/loco2026/:

2nd International Workshop on Low Carbon Computing (loco2026)

10-11 September, Lancaster, UK

The carbon footprint of ICT is rising despite the urgent need to decarbonise society and to stay within planetary boundaries. The operational and embodied carbon emissions from ICT are already estimated to contribute between 2 to 3 percent of the global emissions and new technologies such as AI is driving overall growth in data centre demand, which globally rivals that of entire nations. This growth in emissions from computing is unsustainable and alternative low emissions pathways for computing are urgently needed.

The LOCO workshop provides a forum for radical ideas, early work, and critical perspectives that aim to reduce the emissions from computing.

Joining me this time were Kathleen West, James Nurdin, Youssef Moawad, Giulio Attenni, and Magnus Reid. I am very lucky to get to work with such a bright and friendly group of young researchers at Glasgow! 😊

I believe that research works best as a team sport, with all the obvious benefits, and think that teams work best when there are chances to get to know each other away from the desks from time to time. For example, when there is a tricky flat tire to fix together midway through a bike trip... 🚲 🌬️ 🔧

I had a great time at IEEE #ICDCS 2025. First time that I attended a conference without a talk or helping to organize, so this was a new experience! Of course, also rather nice to attend a top conference after 10 minutes on public transport (and after dropping off the wee one at nursery too ☺️)

Having a good time with Drs Reza Farahani, Lauri Lovén, Ilir Murturi, and Paul Harvey ahead of the banquet dinner

Dr Blesson Varghese explaining how ML can be made feasible on small edge devices in his workshop keynote

Scottish treats in the coffee breaks – Tunnock's Tea Cakes and shortbread too!

As a vegetarian i was "in safe hands" at ICDCS, as this card says, identifying me as "vegi" :)

Next week, around #Neurodiversity #Celebration #Week 2025, a few colleagues from UofG's CoSE College and I are offering #Disability Office Hours. Have a look here, lnkd.in/ePS2hpHN, if you're a CoSE student or staff and you'd like to take up this offer for a friendly, supportive chat! 🙂

Poster advertising the Disability Office Hours of the College of Science and Engineering at the University of Glasgow.

UofG CoSE Disability Office Hours are an opportunity
for students and staff with a disability to talk to a
member of staff with a disability about anything
disability-related. In other words, they are a chance to
have a friendly and supportive conversation with a
member of staff who has first-hand experience of the
challenges that disabilities can pose.

Our definition of disability is broad and includes
all forms of long-term health conditions
(including mental health), neurodiversity, and
sensory and mobility impairments.

We organise Disability Office Hours every semester,
usually around UK Disability History Month (end of
November) in Semester 1 and around Neurodiversity
Celebration Week (end of March) in Semester 2.

Specific dates and a list of colleagues
involved can be found on the College
website (with colleagues' personal
information available in a Sway after
logging in as a staff or student).

It’s been two weeks since we held the 1st International Workshop on Low-Carbon Computing (LOCO), and I'm still buzzing. It was so good to see this community come together, hear about all the interesting ideas and early results, and witness how many care deeply about computer system sustainability! 🧵
