Welcome to the last post of 2017, and no surprise but today I will speak about increased Ethereum (and Siacoin) mining profitability by overclocking GPU cards. Those of you following my blog lately already know - in December I decided to build 12 GPU mining rig and ordered goodies from Amazon. In total spending about $1,147.  The total investment right now covers just the core minimum - motherboard, power supply, PCI risers, RAM, processor and just 2 graphics cards. At the start, I ordered…

It has been a couple of days since my first GPU mining rig is set up and running, making me a couple of extra dollars every day. In these past couple of days, I have learned a lot, mostly tech stuff how to install different components on a motherboard and to connect to the mining pool. In today's article, I will share a few photos and notes what helped to get me here. It all started with ordering details for 12 GPU mining rig from Amazon. It sounds bit insane but I spent about $1,000 just for…

This Sapphire Pulse Radeon RX 560 4GB graphics card is the first I've put on test for mining ethereum. Bought it at about $190 at local Tbilisi electronics shop, but you could get this card from Amazon for about $130. Out of the box, I was able to get 10.72MH/s for Ether and 85.74 MH/s for dual mining Siacoin, on average by mining with this card only I'm able to make about $0.98 daily, which gives about 190 days for ROI. See: I'm Making $0.98 Per Day By Mining Ethereum and Siacoin, and I want…

In this article, you will learn how to set up a Drupal 8 with Nginx, PHP-FPM, MySQL and phpMyAdmin. This article might not be complete, but you will find a lot of useful information Update: How to Install Drupal 8 with Nginx, PHP-FPM 7.2, MySQL, phpMyAdmin on Ubuntu 18.04 - Linode Guide Prerequisites Ubuntu 16.04 - 64bit version. Root privileges. You can get a cheap VPS for $10/mo from Linode. As I've few test Linodes already purchased I'm going to use one of them Follow basic security…

Recently I ordered goodies for my first 12 GPU mining rig, including the motherboard. As I have got a few other PC's I decided to explore, are they optimal for GPU mining, for doing that, I had to learn the motherboard model and version. Luckily, there is a simple command line to run from CMD.  Open up the command prompt in Windows via either the run dialog (Windows+R) or by searching for “cmd” on the Start menu. At the command line, type the following text (noting that there are no spaces…

I love testing ideas and even more than just testing new ideas I love testing them using Minimum viable product approach.   I've been in a crypto craze for a while already - started with buy and hold, added little speculative trades, tried an ICO and now even considering to start mining. Totally insane? Well, I can only agree! In fact, that doesn't even sound like me - you see, I like buying and holding, I even enjoy doing a few swing trades once in a while, but to run a mining rig? Totally…

It has been already more than one year since I've enabled OneSignal Web Push notifications for this blog. Over the past year, the blog has acquired more than 25,000 web push subscribers. Frankly speaking - sure web push notifications are great if used the right way, speaking of me - unfortunately, or for good, as I keep writing on many topics, I still haven't found the most optimal use for web push notifications, as readers of this blog fall into many audiences and demographics. One of the use…

I spent a good amount of time, trying to learn how to implement a better user segmentation on OneSignal. The best I could get so far was the default OneSiganal's out of the box segmentation based on user country. As my blog covers many mutually unrelated topics, I was not utilizing the power of push notifications at 100%. In fact, after getting more than 26,000 subscribers (over a year) I felt afraid every-time I sent out a web push notification, as user targeting was very poor. At OneSignal …

Lately I've been working as a system administrator and helping out a lot to a small company setting up office computers. It involves purchasing office computers, setting up operating systems, configuring LAN and of course security. As these are topics I face on my everyday working day (though i feel more server guy) - I decided to write down my notes, as with time, things can be forgotten. Just recently we faced an issue on port forwarding to enable Remote Administration, see: How To Setup…

In today's article, I'll share quite an easy tutorial on how to configure TP-Link Wireless N Router WR840N for a LAN to allow connections from the internet using Radmin software. For the ease of this article, I will not cover in depths details how to configure Radmin, for that follow official guidelines (or leave a question in comment form). Today we are talking about port forwarding in router setup and firewall settings for Windows 10. Despite I'm providing details for TP-Link Wireless N…
