- Comment on How to deploy a satellite and what are the costs? 1 week ago:
I looked into CubeSats in a previous job. Basically, there are four parts:
- What’s the purpose?
- How to design and build one?
- How to launch it?
- How to collect the data?
Part 1: this is the back of the napkin sketch. What are you trying to do? Weather, water, fire, or air data? Imaging? Has anyone already done this? What’s the plan?
Part 2: you can DIY the whole thing, starting with the CalPoly CubeSat workshops: www.cubesat.org. They’re the folks that started the whole thing.
There are also kits and services out there. One example is Pumpkin: www.pumpkinspace.com, but there are a lot of others like it out there. You want to figure out what sensors you need, mechanisms to orient the sensors, radios, power management, etc. Also, what’s the lifespan before it descends into the atmosphere and burns out.
Part 3: The big problem is launch. You need to eventually get it up into space. There are commercial services, but you’re looking at $50K and up to get into the queue. Another option is to go through NASA’s Launch Intitiative: www.nasa.gov/…/cubesat-launch-initiative/ or ESA’s Fly Your Satellite program: www.esa.int/…/CubeSats_-_Fly_Your_Satellite
These require being part of a non-profit or educational institution. And the waiting list is long. Like, years.
Part 4: OK, now that you got it up in space, what do you do with the data? It’s circling the globe and there’s a narrow window where the radio can connect to an earth station, send the data, and maybe receive instructions like where to point the sensors. Forget about OTA. You won’t have a large enough connection window or bandwidth to do that.
You can roll your own comms, or you can see about using an existing service, like AWS Ground Station: aws.amazon.com/ground-station/. Microsoft had a similar service called Azure Orbital, but they retired it last year.
After all is said and done, you now have some cool data. You’ll want to process it and use it for something. This goes back to step 1. Figure out what’s the purpose, what you want to get out of it, and work backward. You can use the AWS service, pipe it into an S3 bucket or store it in a database, then run analytics and visualizations on it. If you want realtime, it’ll cost extra.
It won’t be cheap, but it will likely be a lot of fun. I proposed several projects in a past life. We got pretty far, but the launch window was years away and by then I was heading out. All this is an infodump of what I learned back then. Hope this helps.

Watched it. Basically, Complex Fluid Dynamics + Reinforcement Learning + Human-guided Design. All very sensible. Nothing to do with chatbots.
Points off for showing stock footage of HTML web source, and unsubtle promo for SaaS platform. Double points off for ‘owl-inspired’ cooling fan bullshit, and skirting the line on becoming a Mahle infomercial.

I was told by a food research lab you could scoop off the top layer (oxygenated) and consume the rest of jams and sauces.
I’m not sure I believe them. They were growing large quantities of insects in a smelly, dank room for protein.

- Comment on [deleted] 1 month ago:
Way back when, MSFT would set up developer meetups and give everyone who showed up a free Windows phone for development. I still have a couple in a box somewhere. People would take them, but nobody wanted to make apps. Everybody was busy enough with iOS and Android.
MSFT even tried to pay companies to port their popular apps to Windows. A few took the money and did the port, but nobody wanted to support it.
Samsung was also trying to get people to write apps for their watches. Same issue. It’s really hard to break in if you’re entering an already crowded market.

- Comment on I ain't risking shit 1 month ago:
I was in an Apple Store for a Genius Bar appointment when these two guys with hoodies and COVID masks walked in and started pulling phones off the displays and stuffing them into backpacks.
It took less than a minute and then they ran off. The security guard just stood to the side and recorded a video. Once they were gone, everyone just went back to what they were doing, like nothing had happened.
Afterward, I asked the Genius Bar guy if that happened often. He said the two guys hadn’t gotten much because they hadn’t refilled the display from a guy coming in and stealing all the phones literally the day before!
The phones were tracked and the cops eventually caught the two dudes as well as the other solo guy.
- Comment on Why does a Local AI Voice Agent Running on a Super-Cheap Soc Matter? 1 month ago:
Advantages of running things locally:
- Saving on electricity, bandwidth, and processing
- Able to customize for individuals or families
- Enhanced privacy
- Option for future federated/mesh applications
- Keeps running when network/cloud goes down (Hello, AWS!)

- Comment on In which ways the dot com craze of the late 90s and the current AI market differ? In which ways are the same phenomena? 2 months ago:
The unbridled enthusiasm is the same.
In the dotcom era, I had friends working at e-commerce startups selling items you could easily find at a store. They even had to buy from the same wholesale suppliers, and try to undersell retail, even though they had additional shipping cost (offset a little by not having to pay local sales tax). So they ate the losses because VCs told them they had to show the only metric was positive customer growth (not profit). All business ideas were “add e-commerce to X.”
In the 2008 crash, even though it was triggered by real-estate debt, a lot of the same tech dynamics were at play, except “add mobile to X.”
A lot of present day AI companies are following the same path. “Add AI to X.”
What’s different this time is that there’s a lot more hardware involved, in the form of GPU and data center expansion. After dotcom, we were left over with a lot of fiber, telco, and home internet expansion which was still usable. This time, it’s not clear what the data centers will be good for if AI crashes out. Maybe crypto-mining.
