I'm building (what I hope to be) your new home for all your photos and videos. It's called PhotoStructure. TL:DR; see https://blog.photostructure.com/introducing-photostructure/ In a nutshell, I've got 20 years of digital photos and videos, spread over tens of hard drives, CDRs, crashed laptops and servers, and takeouts from failed photo services. Nothing I tried could sweep everything into one neat and deduped pile.…

This sounds pretty cool but tbh, if I'm willing to try out a beta product with all my images (and the risk of losing them due to some bug or any other risk) and provide feedback, I'd like to have a bigger carrot than just using the product for free in beta only :)

As a side project, I'm working on a route planning app for running. I'm a long distance runner and travel for work a lot, so I frequently find myself planning a run on one of the many existing apps at 5am in a new city whilst jetlagged. My bugbear is that all the existing apps suck. I want a way to say "give me a running route that lasts approximately 10km and is as scenic (greenery, water, mountains, etc) as possibl…

I've wanted to build something similar for both cycling and motorcycling. There is an app for motorcycling that works ok, but it would be a fun project. Is this open source anywhere? I struggled to get started with working with road data and getting that into a route planning system.

I suspect you're referring to https://kurviger.de/en for motorcycling. This uses Graphhopper's builtin round-trip functionality (it was incorporated by the author of that motorcycling route planner). You can find more about the Graphhopper API here https://docs.graphhopper.com/#operation/getRoute, and it's completely open source at https://github.com/graphhopper/graphhopper

The motorcycling round-trip algorithm is quite crude, it relies on a user to pick a heading and then points N points in a circle on that heading and builds a route between them. It does not take into account any features of the map (e.g. forests, rivers, obstructions, etc). It's sufficient for longer distances though, but struggles on shorter distances.

My project isn't open source yet, but I hope to make it so if/when I finish it!

I'm writing a book that teaches people coding using JavaScript, the book that takes you from 0 (no coding background) to getting a job as a JS engineer. 2 years I ago, I had a hypothesis to see if anybody could learn coding if they tried. To test that, I reached out to random people with no coding background, most of them from underprivileged backgrounds. I figured they have fewer opportunities and are more likely to…

Is 130k realistic for someone with less than 2 years of not just experience but total exposure? I'm not aware of any market supporting that sort of value proposition; that's one hell of a book...

I generally take things which sound to good to be true with a pinch of salt. No exception here.

I am refactoring the report designer from one of my projects, https://apps.shopify.com/export-orders.

The report designer is iimplemented using Datatables.Net library (demo: https://www.youtube.com/watch?v=QQ-viTQARTk) and I am implementing the same functionality and some more features (column renaming, custom column expressions) using VueJS.

I've had this thought. I'm intrigued! Strava has a "Strava Local" but it appears to be automated and is, frankly, bad. Would love to see what you come up with!

I think Strava Local is curated, but I agree with the 'frankly, bad' part of your comment. For my home city of London it has a few of the major landmark routes, but doesn't have anything near my house, nor does it have any of the less obvious but more fun local routes.

My frustration with Strava is that they have SO much good data, yet they do so little with it.

are you lifting weights and exercising? If not get on it ASAP. Revert back to the physical-activity-heavy lifestyle of our ancestors and you'll feel better

If you hate exercise, try physically-active VR games. You don't even feel like you're exercising (although you sure feel it the next day!)

AFAIK that's not enough calories burned to get you into caloric deficit. You need more intensive or longer exercise

Umbrella App.

It's a free, open source app with best practice advice on how activists/journalists/aid workers/travellers can learn about and manage their own digital and physical security.

It covers stuff like travel safety, staying safe at protests, dealing with arrest, surveillance, sending a secure mail or communication etc. Our background is working with activists and journalists to keep them safe, so we wanted an all-in-one guide for anyone who needs help. You can read more about it at https://www.secfirst.org or try it

I was wondering why you choose to go with video data rather than photos. From what I know, for a given feature point, you would rather have pictures with really different point of views. It seems to me video would generate a lot of redundant data, massively increasing processing times for very little gain. What's your experience on this?

They probably are using drone/car/vehicle to capture the imaginery - at least that's the only reason i can think of - i used to do that back at the university. We recorded a video from a drone, split it into frames, and built the mesh using those frames. When drone is competently flown it creates a nice stripe of overlapping frames - and overlapping stripes(i don't know proper technical english translation for that t…

I'm aiming for software to digest the output of a 300fps tethered camera on a drone. Basically an Apertus Axiom beta with a fancier FPGA to use all 64 lanes of the sensor to not have only 150fps, and being able to attach a 40G QSFP+ transceiver to it for data offloading.

Existing software makes hand-picked pictures worthwhile, but I want full-auto behavior.

Near-term I want a construction worker to open the case with the hardware after cleaning his hands, and then showing all insides of the building to the camera, before swapping the storage and getting the data physically back to base for processing.

Also, video capture gets you continuity of motion. Unordered picture collections are horribly expensive to compute with.

I also prefer redundancy to holes in my textures or models ;)

My drone swirls around the buildings, btw. I want VR for walking, not google earth.

Are you on Strava? In new cities I just look at their HeatMap to see where the locals are running.

The heat map is a nice visualisation for the vast amount of data that Strava has, but I don't find it useful for planning runs as an individual. It pretty much just shows where the major roads are in cities (which ironically is what I want to avoid).

Strava's more recent "draw your route" feature is quite cool, but again it requires that you know the area and does not take into account the features of the land.
