I switched to Godot expecting some pain but it was great. Way more depth of searchable stuff on the net to help figure things out than I expected.

If you're thinking of starting a new project and you're experienced with unity, don't be put off making the switch. It won't put you back as much as you think and it's a lot better in many ways, but more importantly it's momentum is going in the right direction

I posted this in a comment but going to post it again at the top level. For anyone interested in discussing this, I highly recommend you read the NHC forecasters day 2 summary. Ignore the media, just go straight to the source.

This is very much unprecedented, despite many here posting that hurricane remnants hit CA all the time.

That's not how this works. It's the water, not the wind. This is completely unprecedented

For anyone in CA or Nevada reading this misguided comment, please read the latest update from the forecasters at NHC:

That's just 5 20tb drives. Some cloud providers will copy it on to them if you send them in, and usually cheaper than the bandwidth cost. Same for ingress

That sounds fascinating... How do you end up with AliExpress vendors sending you EDA?

Yea but grass doesn't grown on methane

Yes 100%.

Get a ublox F9P board and antenna. Couple hundred dollars.

Set it up to do RTK using public CORS base stations (will give you 2cm apx accuracy). You will get a kick out of it.

Then next level is grab the latest rtklib, and do PPP processing.

The RTK step is simple and will boost your motivation to learn more. PPP is also easy to setup, but there are many things you can take to make it more accurate. Each one you will learn about something new. Satellite clock corrections, position corrections, ionosphere and troposphere modelling, receiver dynamics, tidal loading, wind up, etc. List goes on a lot

Once you've done that you'll have a 'feel' for it. From there you'll find your own resources based on what most interests you

And yea, it is fascinating. I'm not bored of it after all this time. New stuff keeps coming out. SSR is super interesting right now

Ive been working with GNSS for the last decade and a bit, and this article and the comments here are a low point for HN in terms of people making comments about stuff they dont understand.

PSA: if you want to learn about corrected GNSS, stop reading this thread now. I started replying to some comments then gave up, most here are more wrong than right.

Not so much. Modern GPS will get a first fix pretty quickly regardless, you don't need to seed it.

AGPS is used when satellite coverage is poor, like urban canyons in a city, also a situation where there are a lot of cell towers and triangulation is somewhat useful

In the unlikely event any Aussie or NZ farmers are reading this, it costs less than $1k to setup your own base station and transmit corrections via a number of RF links. One base station is good to a radius of about 60km, so not enough for large ranches but fine for crops. You can setup as many as you need, then no reliance on L band SBAS

Cell towers have no relation whatsoever to any of the different types of differential GNSS

In my work I have had to evaluate a whole bunch of SBCs, and the Asus Tinkerboard is a cut above all the others.

I expect the quality of this board to be similar

I design low volume specialist equipment, and would love to try these.

Problem is I can't even talk to manufacturers at my volumes, and this probably won't be on Digi-Key/mouser/RS etc for years.

If I were them I would get these out to us little guys through those distributors so more engineers in general are familiar with them.

Something about the honesty in the way this is written I love. I am a fan now of their gear even without reading any reviews.

I just tried to buy one of their APs but looks like they arent available in my country.
