A fun but maybe not easy question as we look forward to #SC25

Which of these most resonates with how you think of yourself?

Can only pick one, can’t say “all of them” - get off the fence & pick a team 😁

1. #HPC/#Supercomputing

2. #AI

3. #Cloud

4. None - no resonance with any of them

1 week until #SC25

3 bits of advice:

1. Prioritise shoes for comfort not smart.

2. Find/force downtime during SC. Enough talks/meetings/receptions done well is better than lots rushed/tired/etc.

3. SC is about people as much as (or more than) technology.

Useful thread by @meredithmeredith.bsky.social on the difference between renting a server and buying access to an established globally present hyperscale infrastructure - including discussion (warnings) around concentration of risk and opportunity
📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).

It’s also concerning. 1/
PSA: we're aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.

Imagine you could visit 5 #supercomputer centres anywhere in the world - but only 5 - to learn the most about the state of the art for #HPC, plus future trends, etc. - which 5 would you choose and why?

Is it time for a #HPC community debate about the cities that are being picked for SC?

#SC25 is really struggling for available hotels near the conference center.

Plus some people are worried about the street safety reputation of STL and other recent SC cities.

Woah! How is it the middle of October already? When did that happen?

Long distance multi-leg UK train travel is gathering friction in passenger experience - ticket website search algos refusing to show best trains or connections, staff that make up rules based on their personal assumptions, crowded trains, etc … my trips to Exeter offer fresh frustrations each time.

One side effect of having lots of LED light bulbs around the house is that you forget you have the occasional bulb that is still the old filament style and also that those filament bulbs get really hot really quickly.

Anyway so I have a blister on my finger now.

Well, the apple lobby have showed up quickly as expected 😁 but where are the advocates for Windows or Linux for a new home laptop?
Thinking of buying new laptop for personal use plus some travel.

Windows vs Linux vs Apple Mac?

I've had Windows & Linux laptops before, keep drifting back to Windows. Never had a mac, but have iPhone, apple watch, ipad, etc.

Tell me your pros / cons of each & convince me which to buy and why!

The HPC (+ AI Infrastructure) Leadership Training Institute this week at BSC hit registration capacity weeks ago - extra places were opened & they went fast too, and people still on a waiting list.

Nice to see the guess of demand to run the first ever HPCLI in Europe was good!

Boarding #BritishAirways for Seattle … oh, nope, crew got on then back off again to say the aircraft hadn’t been cleaned at all, so now we all waiting at gate for estimated 40mins delay before boarding while aircraft gets cleaned.

Hearing the announcement: “boarding complete” for on time departure = good.

Followed by pilot: “there is a fault with the aircraft so there will be a delay before we can go …” = less good.
