Flight search. I hunt deals for Aussie travellers ( https://www.beatthatflight.com.au ), but an inordinate amount of my searching for deals is manual. - initially, all manual - secondly, timers - I know when some airlines do deals, so I go look - thirdly, I found other sites indexing unusually cheap flights, but they're not always the same price on my site - fourth, built a script to search my own site for a route, b…

Thought your username looked familiar, I've seen your site on OzBargain many times.

I always wondered how/if finding cheap flight deals could be automated, and it's interesting to hear that it's as hard as it seems.

Just FYI, your logo and part of the menu disappear off the sides of the site background on my 4K screen.

I am working on Site that helps people, who are in teaching profession, track fees. Often times, small-time tutors are left with using multiple tools like google docs, calendar etc. to track contacts, fees. This is attempt to provide one stop to manage all things.

I'm building a product that aims to get people hosting software again. The internet used to be bi-directional, in that people could host content as easily as they could consume it. We're currently a Kubernetes hosting platform, but I'm working hard on a system that will allow developers to extend our cloud with their own machines at home, in a data-center, or anywhere! From learning to host Minecraft servers at home, to Fortune 10 Software delivery, we don't see a reason why you should have to jump to different vendors and different platforms. Democratize server-side software! https://kubesail.com (YC S19)

We're trying to improve the security of the Internet by replacing Certificate Authorities with a distributed root of trust. DNS is currently centralized and controlled by a few organizations at the top of the hierarchy (namely ICANN) and easily censored by governments. Trust in HTTPS is delegated by CAs, but security follows a one of many model, where only one CA out of thousands needs to be compromised in order for…

This is really interesting. Are you using concepts from self-sovereign identity¹²? Do you think there is a relevant intersection? ¹ http://www.lifewithalacrity.com/2016/04/the-path-to-self-sov... ² https://w3c-ccg.github.io/did-primer/

All blockchains use self sovereign identity. They just don't use that buzz word.

Writing Mathematica software with Stephen Wolfram's support to extend the hyperoperators beyond exponentiation - tetration, pentation and so on, from the natural numbers to complex numbers and even matrices. I do this by extending the iteration of any smooth function to real and complex iterates. http://iteratedfunctions.com/ and http://tetration.org/. Physics has two mathematical methods for it's representation, partial differential equations and iterated functions. My work is more general than physical systems or even the universe because I can consider both measure and non-measure preserving systems. I am looking at AI applications as a system that is tuned to solve for physically possible models.

I'm working on pacing emails to a more manageable, calmer schedule. I'm doing it with essentially a UI-less system which is a rather fun way to produce an app. It simply requires a user to update their email of the website that emails them too frequently with a paced.email alias. E.g. johndoe.shopify@daily.paced.email johndoe.stripe@weekly.paced.email johndoe.github@monthly.paced.email At the end of each period, a si…

I like how this is done, I'd suggest forwarding to another existing email address, for example: johndoe_AT_gmail.com@weekly.paced.email

Then you don't even need a website.

I'm leading a startup nonprofit exploring policy solutions for America's 100 largest cities.

Of course, there are plenty of national and state-level policy organizations; some even dip their toes in the municipal policy scene. But in the cities, most gropus are self-interested or focused on a single issue.

We're trying to fill the gap with original research and projects that operationalize the research of others -- taking, for example, good research and popularizing it, developing components for model ordinances, etc.

Downloading has been resumable since HTTP/1.1 but people uploading content have a less reliable experience. Worse: typically upstream bandwidth is much lower so they are exposed longer to unreliable connections.

Trying to fix uploading through tus.io (low level protocol) and uppy.io (user interface). Both open source and free to add to any project.
