In light of today's Apple Mac Pro announcements, I'll chime in... Problem: Building macOS desktop applications as an indie-developer. Project: Fileloupe for Mac and Videoloupe for Mac Fileloupe is a lightweight media browser that I actually announced on Hacker News a few years back. Videoloupe was just released and is a video player/editor in the spirit of the older QuickTime Pro 7. I work on both of these full-time…

Sorry to go off topic but are you living, holidaying or "digital-nomad"ing in bkk?

Scuba diving computers have become a necessary part of diving. Current models have indecipherable interfaces that hang from dongles or are worn as bulky wristwatches. I have developed a scuba diving computer HUD with a simple graphical interface placed in the diver's mask and is easy to learn and use. Also, scuba divers must maintain neutral buoyancy during the dive. The current method is manual, making it a difficul…

Have you looked into adding navigation / mapping / and comms to your dive computer? My company has a side project building a dive watch for divers. It has a navigation system and communications aspect where divers can send messages to each other and track a dive buddy's position. The project is mostly for fun but there is a market for it.

How do they track position? I know that (eg) GPS and Bluetooth don't work under water (or at least their range is so bad that they aren't useful). Seems like an interesting problem!

Problem: unsatisfied with package management on OS X / macOS Project: rekindle an old project of mine [0][1] Caveat: definitely works (as in I'm using it daily), but not ready for real public prime time as some meta+infra stuff still needs to be figured out. Will post instructions to get things running if some daring folks are interested. [0]: http://www.arch-osx.org / http://www.archmac.org [1]: https://github.com/a…

I've wondered about this myself. My thoughts always ended up deciding that what we need is a Mac equivalent of apt, which relies on the existing `installer`, as apt relies on dpkg.

I'd like to "TRY" before making a bigger cash commitment. I can pay BUT want to have an 1 off article to see the quality. I am not saying free. Just gimme a taste. Before i fork over the dough.

No problem, we have a one article option for $60!

that's what im sayin. I'd pay $60. Let me look for it

Tesla owner needs to cash out and sell his tesla. Opens my app and gets an offer OR uploads to get offers from buyers. I am not sure. What do you think?

Could be helpful to people. Not sure how often it would be used though, since tesla also sells there own used cars. You could also try to scope outside of Tesla's as well. Tesla may have a great computer in it, but alot of cars have computers in it. I'd says start with tesla definitely (since you seem to have already started :) ) but don't be afraid to Branch out!

Yeah so i am working on a dealer side. A dealer gets a tesla and can upload thier inventory. I found a few examples and have to figure out what is the value prop for a tesla owner who can upload his ad to cardotcom/ craiglist / autotrader and the likes. I want make it STUPID easy for a user to post an ad and get value from his $100. I am listing ( develop the market) 100 for free. I am doing it manually right now. But improving and a friend is calling all the used car dealers around here in NY to see if they want to list their used tesla inventory and we find them a shopper / send them a lead do the PPC FOR them etc....

Neoprene compresses at pressure, which means it's less buoyant at lower depths.

Yes, I agree, that is what I was saying also. I just wonder if the human body doesn't also change buoyancy with depth, making neoprene density variation pretty negligible by comparison.

From what I understand, no. The only thing that compresses is the air inside your lungs, but you keep on breathing in & out pressure compensated air, so the buoyancy difference doesn't change as you go down. Neoprene compression has a fairly large effect, pounds worth of buoyancy. Look at this spreadsheet for example, at depth you lose 11.6 pounds of buoyancy due to the neoprene compressing: https://www.scubaboard.com/community/threads/the-ultimate-wi...

You are right! It is a very hard and interesting problem. Radio will not work underwater. Inertial/mag sensors can be small and cheap but the quality is poor. Therefore I have been using some 'intelligent' (hate to use that word these days) processing of the data. It is still a relative position estimate if you can minimize the drift you are good to go. To help, we have communications between divers using acoustics. Using some cleaver DSP techniques and information sharing between divers you can do a lot.
