Install Apache Kafka on Ubuntu 16.04 : Single Cloud Server
Apache Kafka is a stream processing platform which aims to provide a low-latency platform for handling real-time data feeds. Its storage is a massively scalable pub/sub message queue architected as a distributed transaction log making it valuable to process streaming data. Kafka can connect to external systems for data import/export. Apache Kafka is a part of Big Data analysis too. Here are the … [Read more...]
Creating Circuits With Wire, Resin (Tikka Kebab Circuit Design)
China invented fire making and of course invented various cheap basic electronic things for DIY works. And a Japanese discovered first version of Tikka Kebab Circuit Design. Here is how to around creating circuits with wire, resin, soldier and no PCB. Our previous ways were designing PCB at home, using wire wrapping with breadboard design perfboard etc. Inventor named the way ""0'baka" means … [Read more...]
Cache Aware HTTP/2 Server Push On Apache2, WordPress
We discussed about HTTP/2 Server Push. Apache2 is superior web server software compared to Nginx and it supports HTTP/2 Server Push. Here are few examples of HTTP/2 Server Push on Apache2 running WordPress (we are not talking about simple Link Preload) which can make your webpage to load faster over HTTP/2. Properly implementing HTTP/2 Server Push not exactly easy work. At the end, we will learn … [Read more...]
Fail2Ban Log Analysis Bash Script For Report Generation
Previously we gave some complicated commands to our readers who use Fail2Ban and needs some checking. Other way was using BadIPs for creation of graph. Fail2Ban log analysis bash script is for report generation as list of attacker IPs, banned, unbanned, password attempts sorted by date, country. We written this easy script using various commands and we think it is useful to any sysadmin to quickly … [Read more...]
Arduino 7 Segment LED Display Temperature Sensor (TM1637 & DHT11)
TM1637 is a great cheap module and we have some introduction to TM1637, and some TM1637 projects like TM1637 clock, traffic light timer with push button, a planned project to make cooking top digital etc. This glowing temperature sensor for air-conditioned car with Arduino 7 Segment LED display & DHT11 sensor makes a practical sense. Later we will add digital speedometer function with … [Read more...]
What Is Cloud Data Services (CDS)?
Data commonly stored in databases, like SQL or NoSQL database, but there are other types of data like the data we talk about in the context of Big Data. The moment we talked about Big Data, data analysis in the context of data becoming obvious. Of course the logs of web servers are also source of data and they need analysis. For the larger enterprises, sources of data are diverse and their … [Read more...]
Install GoAccess Real-Time Web Log Analyzer : Apache, Ubuntu
Previously we published GoAccess guides for Nginx and Nginx log with GeoIP. Here in this guide we will show how to install GoAccess real-time web log analyzer for Apache webserver running on Ubuntu and in case of Apache you need not to separately work on how to enable Apache log to have GeoIP enabled features. Apache default log itself a standard format. Install GoAccess Real-Time … [Read more...]
Installing GeoIP Module On Apache2, Ubuntu 16.04
We did it before but for Nginx (you can look - Installing GeoIP On Nginx). We need this to use GoAcesss log analyzer like tools, Piwik etc. WordPress like modern CMS use PHP based function and needs no server side work. Installing GeoIP Module On Apache2, Ubuntu 16.04 Needs Some Manual Steps After Running Installation Command. Sample PHP file supplied to test. Installing GeoIP … [Read more...]
Create Own ATTiny 85 Arduino Based Wearables
ATTiny 85 is a programable microcontroller which is actually used in the smaller version of Arduino. If you search on Ebay, Amazon you will find that they costs lesser than $2 per piece. It is obvious, we made a list of components for creating bigger Arduino compatible LED watch with $8. Electronics is really cheap. Those official Arduino boards are development boards and not intended for real … [Read more...]
