This is not an article with lot of bar charts. I am no database expert but I can talk something about database which so called some "WordPress Experts" in their "professional services" possibly has no such options to the clients. Slow WordPress is quite common and blindly increasing RAM like work is not a solution. Talking about InnoDB vs Percona XtraDB vs TokuDB Storage Engine for WordPress is a … [Read more...]

Arduino Fingerprint Scanner Module GT-511C3, GT-511C1R
Fingerprint scanners are definitely interesting but not many things are known these stuffs as Open Source hardware in this niche still quite less and the module is quite complex. Here is a guide on buying Arduino fingerprint scanner module GT-511C3, GT-511C1R buying guide and basic details to not get ripped off. GT-511C3 or GT-511C1R is the part number of the stuff - if you are lucky then it will … [Read more...]
Theoretical Foundations of Big Data : Part 2
This article is part of series of articles on the topic which can be guessed from the title. Theoretical Foundations of Big Data is second part of our series of articles. Readers if not already read, can read our first article of this series on Theoretical Foundations of Big Data. While dealing with large amounts of data, there are certain rules to which the providers and users of Big Data have to … [Read more...]
Theoretical Foundations of Big Data : Part 1
All of us are well aware that increasing digitization of content, increasing use of intelligent systems and their networking in more and more everyday objects are continually generating, capturing and transmitting data to manufacturers or other service providers. Due to the sheer mass of the resulting data, the administration and processing of these data reaches its limits. The intelligent and … [Read more...]
Which Software as a Service (SaaS) Still Important to the Users
All of us use some of the Software as a Service (SaaS). In this article we are discussing which Software as a Service (SaaS) still important to the users as the cost of dedicated, VPS, cloud servers declined and declining to afford & number of F/OSS software increased. It is off-topic matter to mention, yet Platform as a Service (PaaS) apparently failed to convince from developers to the CIOs. … [Read more...]
Arduino LDR/Photoresistor and LED Based Light Meter
These projects are good for the beginners to learn basic things. We are showing a basic light meter, you'll try to add a push button to start and another push button to stop. In previous articles we have shown how to create basic sound meter with microphone and Arduino. That circuit was slightly difficult. LDR aka Photoresistors are more easy electronic component. Indeed, you can directly use a … [Read more...]
Traefik : Reverse Proxy for Docker Containers on Ubuntu 16.04
In our previous guides, we focussed on basics around Docker in Docker Tutorials as part 1, part 2, part 3 and part 4. With Traefik, we can manage configuration dynamically. Here is a Guide on How to Install and Configure Traefik as Reverse Proxy for Docker Containers on Ubuntu 16.04. Official Traefik website is here : [crayon-69ff34a2899b4163254628/] Of course they have a Docker image too … [Read more...]
How to Install and Set Up LXD on Ubuntu 16.04
LXD works with a directory based storage backend. LXD is lxc with strong security. We can install LXD, ZFS and Bridge-Utils on Ubuntu 16.04 and configure that LXD to use a physical ZFS partition or loopback device combined with a bridged networking setup allowing for containers to pick up IP addresses via DHCP on the vLAN. For a dedicated server which runs multiple web sites with Linux containers, … [Read more...]
Arduino and LED Bar Display : Circuit Diagram, Code
LED bar display is actually like multiple LED, it is not like Arduino modules like TM 1637. Here is a guide explaining the basics, circuit diagram, code on Arduino and LED Bar Display. We need no extra library for the LED bar display but we need correct circuit and logically correct code to use this electronic component. Big advantage of LED Bar Display is it is quite cheap, we can use with IC … [Read more...]
List of Electronics Prototyping & Project Materials
After Twelfth grade, in standard countries degrees really matters least for the intelligent and hard working persons in the field of applied science. Several times it has been proved that traditional education mostly good for nothing and humans with no traditional education became the best possible on the niche - Thomas Edison and Steve Jobs are two good examples. And in this era of information … [Read more...]
Arduino UNO Prototype Shield Tutorial
Normally we use breadboard for prototyping and various types of prototyping boards to make an Arduino project permanent. In such case, usually we do not use the Arduino development board but we use the components to build Arduino. However, not all project needs so much effort. For some, making only the non-Arduino part of circuit permanent works fine. In this Arduino UNO prototype shield tutorial … [Read more...]
