Collecting java.util.logging to log4j2

Everybody wants to write a log. And in Java everybody wants to write their own logging framework or at least use of the many different ones. Then someone comes up with logging framework framework such as SLF4J. OK but what was I about to say. As so many times, I had a piece of Java […]

Building a (Finnish) Part of Speech Tagger

I wanted to try a part of speech tagger (POS) to see if it could help me with some of the natural language processing (NLP) problems I had. This was in Finnish, although other languages would be nice to have supported for the future. So off I went, (naively) hoping that there would be some […]

Porting An Elasticsearch Java App to 5.X

Recently I was upgrading some stuff on my search app which makes use of Elasticsearch. The good people at ES had been promoting ES 5.0 for a long time as it was in beta, and now it was out of beta so I figured I might as well upgrade that as well. Did not turn […]

Automating Deployment of my (Micro)Services

So I read somewhere on the internets that microservices are great and we should all be doing them. Being an overly enthusiastic geek to try all sorts of new fads and see how they work, I just had to go and give it a try, of course. So proceed to try to split my project […]

7 bytes of HTTPS on CloudFlare

I don’t do much front-end software engineering. If I can avoid, I don’t really do it at all. Prefer the backends etc. But for my personal projects no-one else is going to do it. I figured I should move to use HTTPS for some of the content. Using my lack of front-ending for past years […]

Locally Debugging Spigot Minecraft Server Plugins in IntelliJ

This time I had to debug some code for a Spigot server plugin. Spigot is a custom Minecraft server. You download the Spigot jar file, run it and it sets up a Minecraft server for you. You can then write custom plugins for the server, using the Spigot API, and drop them in the “plugins” […]

Harharhar said the Santa when capturing browser test metrics with Webdriver and LittleMobProxy

In the modern age of big data and all that, it is trendy to capture as much data we can. So this is an attempt at capturing data on a set of web browsing tests I run on Selenium WebDriver. This is with Java using Selenium Webdriver and LittleMobProxy. What I do here is configure […]

My Little TCP Tunnel

Do you ever wonder what happens when you try to use some driver or client library to access a networked service? Like send queries to a database using a client driver or use a client library provided by some PaaS provider such as AWS, and get back a cryptic error message (or nothing) and not […]

Performance testing with InfluxDB + Grafana + Telegraf, Part 3

This time running the test with the fixed SNMP based router monitoring and with the client-server monitoring as well. Notice in the following graphs how I learned to also put two scales on a single chart, combine line and bar charts, and add units to all the charts. OOoooo, prettyy…. First up, the number of […]

SNMP monitoring my ASUS RT-N66U for performance testing

I noticed I have previously also tried to monitor my ASUS RT-N66U router to see what traffic passes through. You know, just your regular paranoid stuff. However, this time I was trying to monitor the router CPU load and bandwidth use to figure out if delays in my performance tests were somehow related to the […]
