The article said that he was selling radio equipment. I’m sure all of the buyers will be getting contacted and investigated to ascertain if foreign buyers were involved.

This is a cool find! Calendly still has the killer feature of being able to check multiple calendars to find scheduling blocks. Syncing accounts on multiple Google Workspace instances at a time still remains a pain.

That's just the part of the equation when using electro-optical imagery. You're paying to task a satellite, not necessarily a clear picture. To me this will be an interesting test for SkyFi. Casual customers just expect to see the

I tried listening to it with my AirPods on. The enhanced audio sounds much more natural this way, as if I’m in the room with you.

I agree. I was also taken aback for the first few seconds. After those first few seconds, I think I was able to adjust to the sound. This would be wilder if I were in an unconstrained environment with similar enhanced audio quality. It woul

This is incredible. I took a talk recording I made for NeurIPS and passed it through this tool. The improvement in audio quality was night and day. It went from clearly being recorded in a bedroom to a studio-like experience. [0, original]

Sentinel-1 is the current workhorse for all sorts of InSAR things, but as you mentioned, the resolution is pretty meh for things like damage assessment. Beyond InSAR, people have been doing change detection on GRDs to get damage proxy maps,

We do not currently use SAR! High-resolution SAR is currently very hard to find. Vendors like Capella Space are pretty pricey for HADR operations, though they do provide some data for deeply discounted/free prices for major disasters.

Whether or not that data can be used ethically is an entirely separate conversation, one that IRBs have spent decades answering, and a process that LAION completely skirts on the basis of being a company.

It's one thing to link to online content. They also provide a download script to then turn the links into realizable images. This defense, that they merely provide links and not images, is the thin layer of abstraction that their entir

LAION-5B includes images of humans without their explicit consent. Images of people generally involve IRB/HSR. Additionally, almost any IRB will mention that if you’re using data derived from humans, you must go through IRB. LAION ca

This dataset is a massive failure when it comes to ethical research practices. LAION-5B openly indexed copyrighted data that it had no business collecting. They failed to go through an IRB when curating this data. The ethics review for this

As a PhD student alongside Matt, it’s not any intern. Ph.D. internships are much more scoped to specific lines of work and are a way to potentially fund promising researchers for the long term. In fact, Berkeley AI Research has a built-in w

The warping you’re observing is a result of the projection used to display the map on a 2D screen. They actually do use pentagons to solve the tessellation issue.
