Day 5 - Advent of Code 2024

I just completed "Print Queue" - Day 5 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/5
Yes, it's been some time 😏 Will keep going with #golang

Why would someone from #mdpi think it's a good idea to contact me when I have no prior experience of doing molecular dynamics or any kind of chemistry? I mean, yes, my workplace is involved in pharmaceuticals, but why contact the one person who does #CFD?

I very much like the idea! Maybe a reasonable use case for a LLM πŸ˜ƒ

The likely reason why AI companies make such wild and unsubstantiated claims about AI capabilities rather than market them on the merits of what they can actually do is that there is probably no market that will pay enough for these services to recover the cost, let alone the investments.

This latest cancer claim could really do some damage, given a lot of people have trust in Dr. Google πŸ€•

This post is not up to date anymore. As of May I've became leader of the #CFD group at the RCPE. Which sounds like a move upwards, but in reality the CFD group is me myself and I (and two external persons). I have the freedom to like what my bosses think is good for business 🫀

Wow, das hΓ€tte ich Salzburg nicht zugetraut, gut so! salzburg.orf.at/stories/3316... Hoffentlich nimmt sich Graz das als Vorbild um den Radweg um die Seifenfabrik wird wieder befahrbar zu machen.

I submitted slides for #EFDC2; let's see if I adapt them in the meantime. At plenty of conferences I have been to, people have edited their slides literally during their talk. I'm not saying it's good, but preparing the slides a month in advance seems excessive 🀨. #conference #submittedondeadline

Some #running stuff πŸƒ. Currently training for a new half marathon PB and until this week my watch only suggested base runs. This week threshold sessions are weaved in. Monday the first session was 17min @ tempo which turned out to be fine (for reference a little less 4.5km). Today 2x 20min 😡

Good news: Was asked to chair a session at the #EFDC2 πŸ™‚ Bad news: One project that needs to be wrapped up has gone somewhat nuclear 🀯
There are many things to do, but first let's finish the slides for my talk on August 26th in Dublin πŸ˜…

The #EFDC2 is approaching fast, a little over a month left until the conference starts in Dublin. To my surprise I got an email yesterday that I should send the organizers my sildes until August 1st. Hell, I know a lot of people who finish their talk in the session before their presentation πŸ™ˆ

Back to literature review for #protein stuff. Found this in the abbreviations section after the acknowledgments in a paper: "MS masss pectrometry". I mean it is a typo and people make mistakes, but there were only seven abbreviations used and it is pretty hard not to autocorrect that one.

It's 1/sqrt(eps_0 mu_0), sorry typo

I actually don't know who was the first to derive the speed of light from Maxwell's equation, but there is neat trick that c = sqrt(eps_0 mu_0). I can live with a changing speed light (to some degree) but would this alter either eps_0 or mu_0 as well?

The programme for the #EFDC2 is now online 😊. Got lucky and will present first day afternoon and not in the morning session after the conference dinner.
Anyway really looking forward to this conference, here is the link: abbey.eventsair.com/AbbeyEventAp...

Last week was horrible with lots of bad news πŸ™. This week started with some rain 🌧️, which is actually good news after two weeks around 30Β°C 🌞πŸ”₯.
Let's see what the rest of the week will bring πŸ™„

Is there a lot of construction noise at the Physics Building atm? Doesn't the large lecture hall on the ground floor share its windows with the construction site? Thanks for sharing the progress 😊

When do Austrian grocery stores start to use LLMs to run whole stores? Why I am asking ... www.anthropic.com/research/pro...

2019 hat das EU-Parlament ΓΌbrigens den Klimanotstand ausgerufen – auch mit Stimmen der Union.

2025 scheinen sie im Rausch und im Namen der "Entbürokratisierung" alles vergessen zu haben, verwÀssern Klimaziele und Maßnahmen oder stellen sie infrage.
