Last night's ADSN conference dinner at Thai Pothong was fantastic! Just look at the cocktail I had order, never seen anything like it! It had mango, pineapple, and even sticky rice in it. Definitely would go back to this restaurant the next time I'm in Sydney. #ThaiPothong #Sydney #FancyCocktail

Enjoying the Australian Data Science Network (ADSN) Conference at the University of Sydney. Quite a few interesting talks on AI, LLMs, machine learning, and data science. It's been a great opportunity to meet and network with the folks in this area. #datascience #AI #machinelearning #LLMs #ADSN

Off to Sydney to attend the Australian Data Science Networking Conference for a few days. Hopefully the weather will be a bit less gloomy in Sydney.

So Brian Kilmeade on Fox advocates for killing homeless people and later issues an apology but is not fired yet Jimmy Kimmel gets fired for criticizing how the right has put all the blame for Charlie Kirk's murder on the left and Trump's response to the murder. The double standards are ridiculous!
Brian Kilmeade endorses euthanizing homeless people: "Involuntary lethal injection, or something. Just kill them."

The murder of Charlie Kirk was an awful act. Jimmy Kimmel condemned the murder of Kirk but rightly voiced his criticism of the far right for putting all of the blame on the left as well as Trump's response to Kirk's murder. Because of that Kimmel is canceled, a clear violation of free speech!
“What the administration is doing violates the First Amendment and the Communications Act,” Anna Gomez (the FCC’s lone Democratic commissioner) told TNR's Greg Sargent, noting that the government is “using the public interest standard to go after anything it doesn’t like.”

Trump’s Ouster of Jimmy Kimmel Is Much Worse Than You Think It Is
Anna Gomez, the FCC’s lone Democratic commissioner, tells TNR that chairman Brendan Carr’s move violates both the First Amendment and the Communications Act. Democrats must extract consequences.

Australia Post and other Australian-based carriers have suspended most package shipments to the US thanks to Trump's tariffs. I guess I won't be shipping any gifts over for Christmas! Hope Americans don't mind paying more for goods as they will be the ones paying the tariff tax! #TrumpTariffs
Australia Post joins other global mail services and suspends US parcels
Australia Post is taking the extraordinary step of immediately suspending many forms of shipping to the United States, as a Trump administration tariff deadline approaches on Friday.

Attending the Brisbane Data Analytics and AI Bootcamp! Hoping to meet and network with data/data science industry experts! Looks like a good turnout. #dataanalytics #datascience #AI #levelupyourdata

The final instalment (for now) of my blog series on predicting exoplanet orbital obliquities is now live (www.astrobrett.com/obliquity_ML...)! Here I use a simplified binary random forest classifier model to predict obliquity classes. #DataScience #MachineLearning #Exoplanets #RandomForest

This morning at Dept of Housing and Urban Development (HUD) HQ in DC as mandatory return to office began, this video played on loop for ~5 mins on screens throughout the building, per agency source.

Building staff couldn’t figure out how to turn it off so sent people to every floor to unplug TVs.

Part 4 of my blog series on predicting exoplanet orbital obliquities is now live (www.astrobrett.com/obliquity_ML...)! Here I use a random forest classifier model to predict obliquity classes. Stay tuned for the final installment of this series, coming soon! #DataScience #MachineLearning #Exoplanets

Rantings of a madman! The rest of the world should turn their backs on Trump and America. #madman #DonaldTrump

WTF! Sounds to me like Dump wants to forcefully annex Canada via economic warfare. I'm truly embarrassed right now that I'm an American and my heart goes out to Canada. As I'm living in Australia, I will boycott US products and try to buy Canadian products when I can. #Tarrifs #Canada #DonaldTrump

Part 3 of my blog series on predicting exoplanet orbital obliquities is now live (www.astrobrett.com/obliquity_ML...)! I improved the model with physically derived imputation & engineering new features. Stay tuned for Part 4 on a classifier approach. #DataScience #MachineLearning #Exoplanets

While I do want to refrain from posting political stuff on Bluesky and focus on astronomy and data science, this was a really bad look for Elon Musk and America. This makes me embarrassed to be an American citizen.
He did it twice.

Over the past few months, I've been working on an exciting data science project using machine learning to explore exoplanets. I’ve documented my findings/methods in a series of blog posts on my website (www.astrobrett.com/data_science...), so check it out! #DataScience #MachineLearning #Exoplanets

Does Meta enable scammers on their platforms? I've noticed tons of scammer 'sponsored' content on Facebook, illegally using trademark brands (e.g., JBHIFI) to scam people. I've reported these, but according to Facebook, there's nothing wrong with these ads. It's one of many reasons I'm leaving Meta.

I plan on using this platform for data science and astronomy related content, including projects I'm working on. But for my first post, I thought I would share these photos I took of an impressive double rainbow 🌈 from this afternoon after a heavy thunderstorm. #rainbow #thunderstorm #Toowoomba
