I’ve been working on the new “Create an Uber Clone in 7 Days” book for ages. After so much work this is finally almost done! We have a release date: August 16th (yes 2018!). You can already pre-order the kindle edition but you’d get it for free if you buy the print edition which for some inexplicable reason can’t be pre-ordered. UPDATE: Since writing this I’ve added a dedicated book site, I’d rather you share that instead of the link ..

I’m almost done with grad school and graduating with my Master’s in Computer Science - just one class left on Wednesday, and that’s the final exam. Originally I had hoped to graduate last year, but things happened that delayed my graduation year (to be specific, I switched from a thesis to non-thesis curriculum). My final class is Distributed Computing , which I had a project to do. This project included a report. For my project, I compa..

I’ve wanted to see the Tor in person for a long time, ever since reading a fantasy book set in Glastonbury in high school. My wish has finally come true! I’m writing this post from a small apartment called Chalice Lodge on High Street, Glastonbury. To my left is an organic restaurant named Hundred Monkeys Cafe. To my right and just across the street is an organic food store. Surrounding those are a myriad of crystal shops, psychic healing p..

Ten years ago, the iPhone 3G was just announced, the second version of the iPhone ever. A lot has changed since in tech to the point where it is hard even to imagine how we lived before. Ten years into the future… who knows where tech would be? I don’t know for sure, but this doesn’t stop me from making educated guesses. It is also hard to know “exactly” ten years in the future where technology will be in its trajectory, but what is easie....

Last week we installed an airconditioning unit in our house and yesterday a DHT11 humidity and temperature sensor arrived that I had ordered in the past from ebay and had totally forgotten about it. So, I got the idea to monitor the temperature and humidity in the room, to see how well the airconditioning unit works. What better way to do this than use Prometheus, Grafana and a spare Raspverry Pi Zero W I had lying around.

What follows is a set of notes I took during two of the IJCAI Goal Reasoning workshop talks, about rebel agents. Both talks were presented by the same speaker and both focused on rebel agents. These talks were quite short and the speaker had to go fast, so I feel like I missed out on a lot of the information I wanted to record. As a result some parts are obviously omitted and more than usual are written from memory today, increasing potenti..

I am currently starting to learn Scala (to add to a myriad of other languages I have programmed in over my career). We are also in the process of “dockerizing” our application. So I wanted to try for myself getting a simple Scala application running in Docker.

Web development has evolved faster than nearly every other software engineering discipline. The pace of innovation has been relentless, and front-end developers are confronted with new frameworks, tools, and standards for “modern” web development **constantly**. Framework fatigue is real thing. This post Modern Web Development first appeared on Dan Stroot's Blog

There is a fast way to compute the rotation of a vector by a quaternion, apparently noted first by Fabian Giesen. See this blog post . Since the original description/derivation seems to have been lost in the sands of time (pages 404), I thought I would re-derive it. In the derivation below, I will follow the notation of Ken Shoemake in Quaternions . Suppose we have a unit quaternion $$q = [\mathbf{v}, w]$$ The rotation of a vector....

When you first get started learning about functional programming in JavaScript, there are a few functions you grasp pretty easily. Array.prototype.filter is very intuitive, especially if you have worked with a language like SQL which is all about filtering out data. Array.prototype.map is a bit more complex, but you can figure it out pretty quickly if you’re given a few examples.

Key-Id's FIDO U2F token is a (very) small conveniently sized 2nd factor token, supporting FIDO U2F for 2FA/SSV on various sites. I find it a useful accompaniement to my Yubikey In order to be able to use it with U2F on Linux though, you'll probably need to add a udev rule so that the device is correctly detected. This documentation details the rule to use. For reference, this is the detail provided for these dongles by lsusb Bus 001 ..

For a list of actions on macOS, the standard control is an action button as defined in the macOS Human Interface Guidelines . Here’s the definition from that page: An action button (often referred to as an action menu) is a specific type of pull-down button that operates like a contextual menu, without the disadvantage of being hidden, providing access to app-wide or table-specific commands. An action button includes a gear icon when....

Steve just implemented one of the harder RFE’s we had in a while. It isn’t finished but we can already try some of these features and you should be able to try some of these rich types of push messages. The difficulty stems from the way these push messages are implemented differently in the native OS’s outside of the domain where we have full control. As part of that work our entire developer guide section related to push was rewritten ..
