But the buoyancy variation with depth is pretty dangerous, I think. I do not know if that variation is truly the fault of the suit or the fleshy diver.

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.

I've recently been working on a simple-to-use birthday reminder service (simple as in: no need to open any accounts, no need to ever login anywhere, no passwords etc.): https://ReminderExpress.com Just finished working on v1 of this a few minutes ago, by sheer coincidence; it should now be fully functional.

Love the idea of not having to sign in. Got an error message however.

Can you send me a screenshot? Haven't gotten any other reports. Seems to be working from here.

This is awesome! Would be interesting to add BLE Beacon support for autoplay when you walk up to a specific area on the tour.

Thanks! Ya there are a ton a features I think you could add to this - beacon and location support would be very cool.

Great idea! Would it be implementable with Google Project Tango? Currently working on an idea with museums, and they don't want to handle any installations (i.e. beacons)

I have a project idea that might be useful for someone to learn about audio processing (and maybe neural networks?). I like to listen to audio and watch video of podcasts (and lectures and other human speech) at faster speeds. Sometime, especially if I'm trying to "skim" to see if the media is worth listening to carefully, I'd like to listen at 3x or faster. Very often, the limiting factor is the intelligibility of t…

At some point it might become useful to feed the audio in to speech recognition, then feed the result in to a Text-to-Speech engine. You will lose all of your prosody and speaker characteristics, but blind people have their screen readers at crazy speeds so it will stay intelligible.

Project: R.I.P.Link - a tool for finding dead links on the web[0]. The inspiration for this project came from Wikipedia and the Internet Archive partnering to fix broken links on Wikipedia[1]. After briefly searching around I couldn't find any great tools for this, and I decided it would be an interesting side-project. I was also looking for a good medium-size project to improve my Go skills and understanding of conc…

I made a link tester for all the links on my webpage, after I did not maintain it for a while and half the links were dead: https://github.com/benibela/site/blob/master/manage.sh#L33

That's cool I've been kind of thinking building something like this. Are you using Twilio? How are the transcriptions?

Thinking of removing them since honestly, they aren't very good. Yep using Twilio. Would love to chat more if you're interested.

Have you looked at IBM's Speech to Text? - https://www.ibm.com/watson/developercloud/speech-to-text.htm...

Not sure if there is a difference but might be worth trying a few different services.

I have an app for hundreds public libraries. Such libraries have online cataloges where you can search books, or renew books you have lend, and my app connects to their webpages to show all catalogs in a common interface. Or do things the catalogs do not support, like automatically renewing every due book: http://www.videlibri.de/index_en.html

It takes an awful amount of time to maintain, since there are no APIs and I have to parse the webpages. Every other week/month some webpage changes and I need to adjust it.

It has been going on for years, and I need to update a lot of internal things, too. It is all in German, I need to work on an English translation. Often libraries have multiple copies of the same book. Then you want to search the book, select one copy and order that copy. The current version only stores these copies as strings, because each book is a list of string->string pairs, which looks bad when the user is show the string "Copy 1, library building 1, 123456, orderable". (i.e. an index, building where you find it, the signature of, and status). I just made a new version that would show that all such copies in a 4-column table, but it needs more testing before a release. Each library has different columns, and too many columns might not fit on the screen.

And I made my own programming language to minimize the amount of time spend on adjusting the webpage parsing: http://www.videlibri.de/xidel.html

It was just for small webpages, so speed did not matter and its evaluation just interprets the syntax tree, but now I made it XQuery compatible. Someone wrote a raytracer in XQuery, and when I run that in my implementation, it runs quite slowly. I probably need to build a byte-code for it.
