Docker can take a toll on your disk space. Fortunately you don’t have to keep the files in /var/lib/docker and on certain cloud providers like Digital Ocean it’s cheaper to attach a new block volume than to upgrade a droplet to get more disk space. After you’ve decided on a location, simply do: Change /lib/systemd/system/docker.service: Then: When you’ve verified things are working, remove the old docker directory.
OpenDroneMap does an excellent job at post-processing aerial images. Fly the drone, download the images, process, wait a few hours and get your maps and 3D models. What about real-time? Real-time reconstructions present several challenges and requires a different approach. For starters, using only images as input, without an RTK system and accurate IMUs (better GPS and inertial sensors) you just can’t estimate the camera positions quickly enough. By relaying just on standard GPS and the on-board camera pitch/yaw/roll readings, […]
Have you heard of Mastodon? It’s a decentralized and open source twitter-like platform using open standards such as ActivityPub to function. Among many other features, it has no ads and a chronological order feed. In short, it’s awesome. I’ve tried to explain to my wife the concept of Mastodon. “It’s like Twitter, but you can install it on your own machine. And you are not isolated, if somebody installs their own Twitter, my Twitter can communicate with their Twitter”. Her reaction was like: […]
As an Aikido practitioner, I find the possibilities of VR very interesting for introducing new people to Japanese martial arts. Here’s a toy demo made in two hours. I’m hopeful I’ll find some time to expand this into a full game at some point in the future…
For a finite-size system to persist in time (to live), it must evolve in such a way that it provides easier access to the imposed currents that flow through it. (Adrian Bejan) If you’ve never heard of the Constructal Law, a good place to start is Wikipedia. While we can criticize at length its universal validity as a “law”, there’s some pretty good evidence that it applies well to human-made processes and designs. And software is a human-made design. How […]
It’s been a while since I’ve designed some icons. I’ve based some of them out of the IcoMoon dataset, made some from scratch and colored them to match a palette. These are going to be available as part of VirtualGIS‘s first Maple release. Stay tuned.
AR is a particularly interesting technology when combined with geospatial. AR provides an intuitive interface to navigate and understand the world in 3D. Some geospatial applications need precision. Consumer phones and tablets’ GPS units are not particularly accurate, so this is often not a concern. If we encode latitude and longitude data using single precision floats, we can expect to be off. How off? So if we need sub-meter accuracy, we need to exercise care. Mapbox Unity SDK makes it easy […]
I bought an Oculus Rift. Like with most technologies, I’m usually a “late adopter” (for developer standards) since I enjoy more tested products and lower prices. I was quite impressed. Although the video resolution is still far from HD, you are tethered via cable and need several tutorials to get the hang of the touch controllers, the experience is amazing. No doubt, this is the future of videogaming. If you can fork out the money to buy a serious gaming […]
I’m not going to write a long post about the debate on whether people working from home are more productive. I’ll let this article about a 2-year Stanford controlled study do it: https://www.inc.com/scott-mautz/a-2-year-stanford-study-shows-astonishing-productivity-boost-of-working-from-home.html In short: 500 employees were divided into two groups One group working at the office, the other at home Telecommuters worked the equivalent of an extra full day of work, attrition decreased by 50 percent, they took shorter breaks, had fewer sick days, and took less time off.
