Come work with us at @developmentseed as a Cloud Engineer! You'll be developing tools to handle lots of 🌎 Earth Observation data, manage ☁️ cloud infrastructure, and work with open source 🤗

Nice to have is some familiarity with cloud-native formats like @zarr, Cloud-optimized GeoTIFF, GeoParquet, etc (or a willingness to pick them up)!

Application details 👉https://developmentseed.org/careers/cloud-engineer (deadline Friday 29 March 2024).

Geographic considerations are largely missing from the ongoing & in discussion.

We've written up some thoughts to start this discussion: https://agile-giss.copernicus.org/articles/4/42/2023/

... including a framework to evaluate models from several sustainability-related angles, including , intensity, , and implications

How do you approach questions of sustainability & in your work?

@weiji14@mastodon.nz avatar

Thanks @underdarkGIS for starting this meaningful discussion on sustainability! @djh, the NASA/IBM Prithvi 100M model is actually 'small' in comparison to others like Scale-MAE (323M param, https://github.com/bair-climate-initiative/scale-mae) from the BAIR group, or the 2.4B param model from SI Analytics (https://arxiv.org/abs/2304.05215). See also the discussion in this thread - https://news.ycombinator.com/item?id=36985197

But best to steer clear from the assumption that more params = better model. It remains to be validated on many use-cases.

The peak of Chinese New Year for me is on the ninth day in Penang, when the whole neighbourhood comes alive with fireworks, firecrackers and well, setting fire to golden paper. 拜天公,literally praying to the heavenly grandfather or Jade Emperor, involves lots of fruit offerings, smoked meat, and sugar cane for some reason. Part of the rich Hokkien culture here in the community that still values tradition.

Back in after three years, feels good to be home 😭 Nice to see all the Spring Festival/ decor!

Will have an overnight stay at a capsule hotel before I jump on my next flight to 🤤 Also need to find my accent back and get a refresher on new Malay slang. Sudah berapa tahun tak guna lah, tak pandai cakap lagi 😂

Two signs saying Welcome to Malaysia after picking up luggage and walking into the Arrivals area.
Entrance to CapsuleTransit hotel at Kuala Lumpur International Airport 2 (KLIA2) Level 1.
One very cozy bed in a capsule hotel which is inside one of those metal container boxes (can see the paneling right bwhind the pillow). There are these lovely wooden walls at the sides, and a small pull down table with a mirror behind it.

To set the scene a little bit, here's my basic office setup! The poster above holds a special place in my heart as it's the first proper I stepped foot on back in 2018! I remember how it took a good day to walk across the glacier trunk, and it puts those satellite image pixels I see on screen into proper perspective on land.
