If you want some in-depth technical details on how VORs work, I found this video very helpful. It goes into many of the details of the analog radio engineering:

venti··on All the stupid startup/app ideas I've had so far
Here is a German company that created a device where you can donate by putting cash into the collection bag or by swiping your card. You can even change the amount by turning the handle.

venti··on Starlink Maritime
Yes, you are right. I had not seem the price tag when I posed the question. This product is for merchant ships or yachts and does not make any sense for small boat owners.
venti··on Starlink Maritime
Is anything know about the power consumption of the Starlink antenna? Does the maritime version use less power than the conventional unit?

The fixed-location version of Starlink consumes around 60 to 100 W constantly which is problem if you want to e.g. use solar panels on a sail boat to supply the device.

venti··on How toilet paper is made (2014) [video]
If you speak any German, the children's TV show "Sendung mit der Maus" did a more in-depth movie about making toilet paper: https://www.youtube.com/watch?v=DwSPihWGOCI
venti··on Debugging a Live Saturn V
"We resealed the cabinet, signed off on all the paperwork and got the out of there without any more sight seeing."

That's the NASA spirit!

venti··on Ask HN: What are your favourite self-hosted tools?
InvoicePlane is a superb tool that I regularly use for writing, sending and tracking of the invoices that I send to my clients: https://invoiceplane.com/

I wish it had a proper API, though.

Another similar project is Mycroft: https://mycroft.ai/get-mycroft/
venti··on VR social productivity app Bigscreen raises $3M with Andreessen Horowitz
This reminded me of a project by Sun Microsystems called Project Wonderland. They created a virtual world in which you could attend meetings and look at slides together with other avatars – although this was not in VR.

Here is a demo video: https://youtu.be/-CFOGDBFKrk

Another community radio from Berlin (with a real FM frequency): http://www.88vier.de/
venti··on Williams tube – cathode ray tube used as computer memory
There is an art installation that uses cathode ray tubes: http://www.alpha60.de/art/love_letters/

I guess that they probably don't use the tubes as the actual memory. But it looks extremely cool.

venti··on Modelling game economy with Neo4j
There will be a Neo4j hackathon for beginners in Berlin, Germany later today: http://www.meetup.com/graphdb-berlin/events/222114664/
venti··on Ask HN: What will be the future for email?
Wow, I had the very same idea. But everyone I told the idea basically said: "email is a horrible protocol stack, you don't want to build anything on top of it" or just something like "email is dead". I still think it is good idea.
venti··on PyPy.js: A fast, compliant Python implementation for the web
yes it can: import js js.globals.document.getDocumentById("...")
venti··on PyPy.js: A fast, compliant Python implementation for the web
Yes, in his talk at https://www.youtube.com/watch?v=PiBfOFqDIAI&t=1355 Ryan Kelly already showed a Python 3 version of pypy.js

venti··on Thrust: Chromium-based cross-platform, cross-language application framework
This is great! Installed it via PIP and it just worked. I would love to see this combined with https://github.com/enthought/jigna / https://www.youtube.com/watch?v=KHSXq5jfv_4 .

venti··on Radios Had 'Like' Buttons Before the Internet Existed
As far as I can tell, it should have worked like this: The devices would turn on at approx. 3 am and then draw a current from the power outlet. Someone at the power plant would then look at the Watt meter and from the reading they would know what the outcome was.
