I would love more & cheaper VIA Rail trains in Canada as well... Especially when so many train cars are running empty! https://emptytrains.com/ (petition started about a year ago)…

I’m not the GP, but I feel like “unlearning” often relates to the need to feel certain. When looking for a solution, is the path straight? Or is it curvy, full of alternatives that appear strange at f…

The mapping engine is CartoDB, but I (seriously) doubt that this copy protection was implemented by them. They're much more serious & better at writing good code. You can also see that the en…

Extremely interesting, thanks for this clarification. For those curious, it's documented here[0] -- search for "To ensure that resources are distributed across the Availability Zones for a r…

The Verge article should have linked to https://twitter.com/youtubeartifact (with no 's' at the end)…

The Verge article links to an incorrect Twitter handle, it should be @youtubeartifact (and not youtubeartifacts with an 's'). [0] There's a great tutorial/article here [1] on datam…

Yes! It’s sometimes even more than that, going up to 55 degrees (measured at the St-Laurent/René-Lévesque crossing), which makes North more West than North..! Street name suffixes follow the “Mon…

Check out Amulets (a great musician) who once sold a variable speed tape player in his shop [1] There's also the fascinating OM-1 Cassette Tape synthesizer [2] -- it varies the pitch of the tape …

Have you already negotiated with them? (@techjuice brings up a great list of points which could be negotiated). Is the contract signed? Is 100k their first offer? You could contact 10x Management (the…

That’s exactly what I meant.

The GP is me. :) I apologize if my original comment was not clear, or could leave itself open to a different interpretation. I really did mean that when someone in an emergency situation needs help, p…

This is not about opening a backdoor that would allow 911/etc. to request your phone’s location. It’s only about sending your location when you specifically ask for help in an emergency situation…

Cheers :) For those who can read/understand (or are learning) French, here’s a recent radio interview (there’s a photo of the medal as well in the article): https://ici.radio-canada.ca…

I absolutely agree that any new solution will need to be transparent / obvious / non-3rd party app based. While getting Apple and Google on board may seem like a tall order (I’m sure it is),…

Thank you, dang. I love and owe this community a lot, and would be thrilled to involve it.
comment
I’d love to talk more, if you can. My email in my profile. As stated in a comment above, I think that this should be a global nonprofit. Mapping tools should be made for free to emergency responders. …

I’d love to talk more if you can. Email in my profile. My plan is to do this as a nonprofit. Build great mapping tools and offer them for free to all worldwide emergency responders. PSAPs have a role …

Thanks for the link. I think that this needs to be on mobile OS level to be effective. The good news is that there are only 2 major ones. See https://crisisresponse.google/emergencyloc…

This is an extraordinarily important and interesting “space” ripe for innovation. A few weeks ago, I was awarded one of the highest civilian public awards from the Commandant of the US Coast Guard in …

I’ll definitely try it, thanks! I’ve been “on” grayscale on my phone for a few months now and I’ve enjoyed it very much. One “proof” that I have of grayscale’s benefits is that when I switch back to c…

I agree that the value of this is not perfectly clear, considering what the Stripe dashboard, and Stripe Billing specifically, offer. I've been wondering for a while what are good Stripe Checkout…

Same! I also remember the CueCat's XOR-based ""encrypted"" output :-) Found an article from 2000 on this! https://www.securityfocus.com/news/89 …

in addition to that, wouldn't it have access to the MAC addresses of the wifi networks around you, and more importantly, be able to do a geo-ip check?

Thank you, great video! This 30 minute movie from 1960 explaining mechanical typesetting is absolutely fascinating if you're curious: https://www.youtube.com/watch?v=EzilaRwoMus …

Do you know of specific demand? Would you mind contacting me (gs @ my HN username .com) to chat about this? Thanks!
