Show HN: 2025 California Wildfire Satellite Images

https://california-wildfire-satellite-images.org/

I built a website for comparing satellite images from ESA Copernicus Sentinel-2 of Southern California from before and during the January 2025 wildfires. The extent of the damage to vegetation and buildings is clearly visible from these images.Although Copernicus Sentinel-2 data and tools are open and free to use via Copernicus Browser (https://browser.dataspace.copernicus.eu/), I hope that...

> When faced with a hypothetical expense of $400, 63 percent of all adults in 2023 said they would have covered it exclusively using cash, savings, or a credit card paid off at the next statement [...] 37 percent of adults [...] would not have covered a $400 expense completely with cash or its equivalent

Thanks for link; this post is indeed a dupe of that one.

Add musician Jonathan Coulton to that list: makes ~$500,000 a year without having ever signed on to a major label.
This is a good lesson for everyone who builds online communities: Some design decisions that are acceptable to the majority, like the real-name policy, harm groups of people who are already marginalized.
The Kelvin problem: what is the optimum way to partition 3D space into identical cells, such that the surface area between them is minimized? Lord Kelvin conjectured that the Kelvin cell gave this optimum partitioning. This conjecture stood for 100 years until Denis Weaire and Robert Phelan found a better cell in 1993.

Maybe.

One of TED's purposes is to bring together people with ideas and people with the capital and influence to make them happen.

You need to massage your data to get more meaningful results.

It might be interesting to compare your word counts with the word counts from a general-purpose word corpus, then pick out words that appear more frequently by a statistically-significant amount. Something like Amazon's statistically improbable phrases algorithm.

World of Goo, another excellent indie game, also reported a 90% piracy rate two years ago. The developers calculated that percentage from the number of users on their high score board, which were much more than the number of actual online sales. They were very gracious about it, deliberately choosing not to put any DRM on their software.

Sad as it may be, putting DRM might not increase sales numbers significantly. It just makes crackers more determined. Such was World of Goo's reasoning against DRM.

My hunch says that this is a culture-specific study. The findings might break down in some Asian cultures, especially those in which it is polite to speak highly of everyone, regardless of one's true feelings.
Given the nature of this community, if HN runs ads, I'd expect to see links to user-made alternate front-ends and ad-blocking extensions, right on the same page.
Re:Ask HN: How do I get involved in open source projects? on Wednesday August 04, 2010 @03:26AM (#1573896)
Similar thread: http://news.ycombinator.com/item?id=1518619

Start by helping software projects that you already use. You will have personal insight as to where the bugs are.

Start with projects that you personally use and enjoy! You'll have more insight in the project, and you'll feel more motivated. (e.g."I'll write a patch for feature X becuause I want to see it in the next release.")

Look for projects that are in the middle stages of maturity. A project that is too mature will require technically difficult work; one too young will require lots of discussion on design and specification.

Work on easy tasks first, such as minor bugs or gaps in documentation. These tasks tend to finish faster, and they'll encourage you to go on to tougher stuff.

Get familiar with the tracker (e.g. Trac, Bugzilla) and repository (e.g. SVN, Git, Mercurial). In particular, know how to create and submit a patch. Most projects rely on these tools for collaboration, so you should cater to their workflow processes.

Good luck!
