If your CGO development toolchain depends on external dependencies such as system libraries, or you want to develop on an older version of go while having a different version on your host, you can use a docker container and mount the source from your host machine and build the project inside the container. This can enable us to have a consistent development environment across various developers and their host systems without having to modify system libraries.
I have recently stopped using facebook, but I really miss the convenience of the birthday notifications. I tried to find the .ics which you could export from facebook events page to your calendar program but it was nowhere to be found and I thought I would have to script scraping it myself. A quick search on github later, I found that someone had already beat me to it. You can find the repository on github and follow the documentation, but I have documented the steps I followed below:
Sometimes old projects and libraries require certain specific system library versions that are hard to reproduce, or cumbersome to replicate on our development environment. Docker can be used to simplify the build process of these projects and it is often a lot faster than starting a VM in your machine and using that to build these projects. I recently found out about such a project at my workplace. This was a C++ binary that was statically compiled, so there was no issue with distribution but the build process had become very complex over time.
Three months of self inflicted digital pain and how it changed my habits Last December, I decided to start an experiment and adopt a new launcher called Siempo apart from the OnePlus and Nova launcher that I’m used to since I started using Android. After three months, even though I have stopped using it, I have observed some changes and would like to share it with my readers who are also interested in digital well being.
Go recently introduced a heavily requested feature that allows programmers to set socket options before accepting and creating connections. You can find a mention of this in Go 1.11 Release Notes. Although, not many have written on this and implementing this is a bit confusing due to a change in the way one has to implement this. So I decided to share this with others who might be interested in using this feature.
Suppose you are in a situation where you want to watch a movie on your TV or monitor but don’t want to use speakers. Maybe you are looking to listen to an audio book stored on your laptop but don’t want to transfer it to your phone. Or you just want to buy an audio jack splitter. Look no further, PulseAudio to the rescue. PulseAudio provides streaming via SimpleProtocol on TCP via a simple command.
Convolution It is a matrix operation in which we add each element with local neighbors with respect to the weight of the kernels. Mathematically, it is the element-wise product of each element of the kernel with the image-piece followed by a sum. These filters can be used to detect various things like edges etc. Filters/Kernels Filters/Kernels capture features in their receptive field using matrices containing values (weights) with convolution. A higher result of this operation implies that the feature captured by the kernel is in the image, and a lower score implies the opposite.

I had originally written a Lyric API as a hobby project way back using Node. I published it on github as a combination of API server hosted on heroku along with a library hosted on NPM. It still gets 50 downloads a week and the hosted heroku API server is actually used by many people even though it offers little to no functionality. I was recently looking at wtf dashboard and even contributed a small patch to it.
Suppose you have a HTTP request to be sent but don’t care about the result or errors. This request is sent through a function which is usually called inside a goroutine and is not in any way a core aspect of your main logic. The only important part is forming the actual request and the payload. When you wrote this function, you did not write tests as it would be a pain to make the function return something and check it.
