Special relativity, faster-than-light communication, and absolute time and space

Summary: Faster-than-light (FTL) communication is traditionally thought to violate causality according to special relativity. However if there is an absolute space and time (absolute reference frame), causality violation is avoided. Instead observers can detect and measure their speed relative to the absolute reference frame. The standard story Faster-than-light (FTL) communication is thought by some to allow signalling back in time, th....

Streaming using a Raspberry Pi Camera to Twitch in Full HD while injecting audio from rtl sdr

I have found the right setup to stream in 1080p from a Raspberry Pi using the camera to TwitchTV while injecting audio on the fly! Create an account on Twitch and grab you stream key in the Dashboard. This stream.sh script will create a FIFO start rtl_fm at freq 162.550M to listen to Canada weather bulletin (use your local NOAA channel) and inject and encode the audio to the existing h264 stream from the camera then stream it to twitch usin..

If you really want a high end electric car, and you have the money, then you can buy a Tesla. You’ll end up paying through the nose though. It is super expensive, and that is not just because it takes a lot of work and resources to make. It is expensive, because Tesla wants the profit, in order to reinvest it into energy projects. No way you can get a similar car cheaper. Unique products like Tesla cars have no alternatives, so the people....

Occasionally you may want to hide a method from appearing inside the fabric listing of available tasks. Usually its some sort of helper method you have created that is shared by multiple tasks. So how to hide it? Simply prefix with _ For example, def _apt_get (packages): '''Makes installing packages easier''' sudo( 'apt-get update' ) sudo( 'apt-get -y --force-yes install %s ' % packages) When listing t..

Showing or displaying the available tasks inside a fabric fabfile is one of those things that almost everyone wants to do at some point and usually works out you can just request a task you know will not exist (usually found through a typo). However there is a way to list them built into fabric itself. The below are all methods which can be used to display the currently defined tasks.

Despite having been around for over 20 years, HTTPS always remained very lightly adopted – until 2016. Data from two independent sources shows that HTTPS adoption more than doubled from 2015 to 2016. Snyk CEO Guy Podjarny digs into this data.

SimpleObjectCache is a very simple permanent, cross-platform, asynchronous key-value object cache for .NET. It comes with built-in SQLite 3 support. Alternative backends can be added by implementing the IObjectCache or IBulkObjectCache interfaces. How it works First, you need to set the ApplicatioName. This is also going to be the folder where your cache will reside. Depending on the host OS the location of this folder might be differe..

Annoyingly most cloud providers have an irritating habit of not adding any swap memory to any instance you spin up. Probably because if they added swap to the instance the disk size would appear to be smaller then it is or if they had a dedicated swap partition they would have to bear the cost or again use some of your disk space. Thankfully adding swap to your Ubuntu linux instance is fairly easy. The following task when run will check i..

On Monday this week, the Prometheus authors have released version 1.0.0 of the central component of the Prometheus monitoring and alerting system, the Prometheus server. (Other components will follow suit over the next months.) This is a major milestone for the project. Read more about it on the Prometheus blog, and check out the announcement of the CNCF, which has recently accepted Prometheus as a hosted project.

With the advent of cloud computing where you spin up and tear down servers at will it becomes extremely useful to pick the hosts you want fabric to run on at runtime rather then through the usual env.hosts setting. This allows you to query your servers through your cloud providers API without having to maintain a list. This can be a more powerful and flexible technique then using roles and in a devops world can save you a lot of time.

The package mock-require is useful if you want to mock require statements in Node.js. It has a simple API that allows you to mock anything, from a single exported function to a standard library. Here’s an example: app/config.js app/services/content.js test/services/content_spec.js

I was stuck on a 14 hour flight last week, and to my disappointment, only one of the two headphone speakers were working. The plane’s media centre has an audio connector that looks like this: Someone should consider probing this USB port. The hole to the left is smaller than a 3.5mm headphone jack, and designed for a proprietary headphone connector that I didn’t have, and the two holes to the right are part of a different proprietary c..

It all started with Glitch, a tiny algorithmic music composer. I spent lots of time deciding whether I should choose a native approach (e.g. C++, Qt, RtAudio) or an HTML5 way. After all I decided to give HTML5 a try - there is JavaScript which I still like, WebAudio that runs everywhere, UI that can be ported to desktop thanks to Electron, and I’ve heard browsers are really good at performance these days.

I have been traveling for about 40-something days now, and I don’t feel the way I expected. I hadn’t traveled around the northwest USA nor much of Europe before so I expected that I’d want to spend every day exploring around, to see the local history and culture. On previous, short vacations, I had spent most of the time going from one attraction to another. And I did explore for a while. I drove around between cities and national parks, ....

We are born, we live, and we die. Yet, humans presumptuously want to ply meaning with their existence. What am I — Just a coincidence? What makes me special, am I distinguishable? We're not blind and won't be satisfied with the unlaborious mythological answers. Which are only enough for the simple minds. The essence is there, somewhere downstairs...

Trying to use the keywords as variable names or function names are not permitted. Any code which previously used any of the following keywords have to be changed before a concepts-enabled compiler will successfully compile and build. Concepts ..

Preface As software engineers we invest time into thinking about the problems we are trying to solve every day. Sometimes the problems we face are small or simple. Other times they are large and complex. Either way, we can usually draw from our experience to find a path forward. While coding, we run into a lot of different bugs. Often, they are simple typos or a misuse of an API. These problems do not bog us down very much, and they are qui..

While visiting Amsterdam I explored the Van Gogh Museum. Seeing his paintings and listening to the audio guide, I learned about his effort to become a better painter and about his personal story. What amazed me the most was how he made himself a “genius” through hard, dedicated work. (if I got any of the things below factually wrong, please let me know!) Vincent Van Gogh was prolific. He “shipped” a lot of paintings, and did a lot o....
