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…

I've always wondered how flight search sites develop a system for such a difficult problem with minimal API options and Google limiting access to QPX. There seems to be a lot of data fragmentation in the travel industry too. How do you automate under those constraints? Are there good alternatives to QPX?

I work on software that's used by NASA (and other organizations) to model spacecraft missions. This project spans the gambit of interesting problems in computer science: numerical methods, high-fidelity orbit modeling, orbit determination (using Kalman filters to estimate spacecraft state), complex 3D visualization, language parsing, IDE design, and many more topics.

It's definitely one of the most interesting projects I've ever worked on!

Alleviating homelessness using technology and data.

I recently learned that homelessness is not just about the people you see on the street every day, but that homelessness is in fact a funnel that people fall deeper into as their situation becomes increasingly desperate. At the bottom of the funnel are the aforementioned group known as the "chronically homeless". The top of the funnel however, looks a lot different, it consists of people who might be couch surfing with friends, sleeping in cars or moving between motels. This group is known as the "hidden homeless". We likely encounter this group every day, at work, in the coffee shop, at the gym, but they look just like you and I so we fail to recognise their situation.

The "hidden homeless", at the top of the funnel, actually make up the vast majority of the homeless population. What's even more surprising is that this group overwhelmingly has access to technology, 90% have access to a smartphone or laptop with internet access.

The not-for-profit organisation I am involved with called Ample Labs (www.amplelabs.co) is working on developing chatbots to more rapidly connect this group with essential services. This allows us to get a better understanding of their behaviours, what services they use and how effective they are. This has two benefits - first by connecting the 'hidden homeless' with essential services quickly, we make it less likely that they will fall further down the funnel into chronic homelessness; secondly, it provides us with essential data that we share with cities to inform policy making.

The long term hope, is that by using data to prevent at-risk populations from falling deeper into homelessness we can combat the problem at its source and start to eliminate homelessness before it even begins.

Pivoting my parents' homegrown ERP business from the traditional software sales model (one-time sale with annual support contracts) to a SaaS model with MRR to grow and scale the company. This also comes with changing the organization’s mindset and tools used. I have to say that the technical challenges of bringing in modern web technologies to interface with legacy systems has been an interesting (and frustrating at…

That sounds really cool -- I'd be interested to hear more about some of the hurdles you've encountered integrating modern web tech and old enterprise software. Any particularly notable challenges you'd be willing to share?

Aggregating virus spread data to visualize for Wikipedia. Hacky but working. https://github.com/globalcitizen/2019-wuhan-coronavirus-data...

Increasing food safety and security plus availability and choice in urban environments using robotics to automate food preparation and software to manage operations and logistics. Hopefully also make money. Differences from web stuff: includes embedded, mobile, electronics design, mechanical design, fabrication, business, cross-border operations, food safety regulations, etc.

Thank you for working to fix a problem that would materially improve people's lives. I have a lot of respect for that. Finding a way to have both a technological and social impact in a single project is one of my longterm goals.

Homelessness is a topic I know embarrassingly little about. What has the data led you to recommend to cities, policy-wise?

It seems like large-scale data collection should be (but isn't) used to inform many public policy decisions. Another area where I think data could have a huge impact is studying how the punishments that criminals are served in court affects their outcomes later in life, and requiring judges to factor that data into their verdicts.

Creating the worlds best IP address and domain name APIs and data sets, at https://ipinfo.io and https://host.io.

We've solved scaling and reliability (we handle 20 billion API requests a month), and we're now focusing almost all our efforts on our data quality, and new data products (like VPN detection).

We're bootstrapped, profitable, and we've got some big customers (like apple, and t-mobile), and despite being around for almost 7 years we've still barely scratched the surface on the opportunity ahead of us.

If you think you could help we're hiring - shoot me a mail - ben@ipinfo.io

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…

Great idea. My suggestion: why not use the Gmail-style johndoe+spotify@ suffix? Just because people would be more used to it. That way johndoe@ also would work.

Characterizing the effect of near-surface humidity and wave action on Ka/Ku band satellite transmissions from a surfboard-sized autonomous swimming vessel. I have a little sensor platform, and customers that want it to do a whole lot more. Bandwidth can be hard to come by 6000 miles from the nearest human. Also, working on how to integrate a small team of hackers into a big team of production oriented engineers. Maki…

I’m surprised there’s so much demand for that. Also I bet you’re excited for starlink.

The ocean's a big place, and really hard to operate in. I'm looking forward to seeing how low power the terminals end up consuming!
