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. There has been a recent surge in people starting to restart blogging even though on closed platforms like Medium, but I guess it at least that is searchable outside from search engines, and hope to see more self hosted blogs following Hackernoon’s recent split.
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.
I had an old Samsung N150 netbook lying around in my parent’s house. It was an amazing netbook and I remember fondly using it when my parents were not using it to browse the internet and sometimes even use it for school work. It came with Windows Vista if I recall correctly but I had installed Windows XP service pack 3 on it because as we know, Vista sucked! Well, the netbook was very solid, it even ran small games such as Fifa Manager etc and came with a solid keyboard, ethernet and VGA as well for connecting to a big screen.
After diving into Spacemacs yesterday, I was able to setup LaTeX properly. Only SyncTeX is left to be setup although, right now I can live without it. After tweeting about it, I got a reply about setting up Python on Spacemacs. I had installed the python layer but had not tested it. There was no hitch, although I faced a small issue with having python2 as well as python3 on my system.
I have been using Vim for text editing and even Vim mode even in Sublime Text. Although, I wanted to use Org mode so I switched to Spacemacs with Evil mode that gives the best of both worlds. I had been using TeXworks and TeXstudio for editing and building LaTeX documents but now that I have Emacs, I wanted to try out the pdf-tools layer and latex layers so that all my work can be done from inside Spacemacs itself.
I downloaded a .rpm and double clicked it to install it and it started yumex-dnf. But for some reason it crashed and dnf was locked. I fixed it using yumex-dnf --exit and installed the rpm using sudo dnf install cacher-1.1.10.x86_64.rpm
