In case you have no idea what to read next …

The list of the books, I want to share with you, is totally unordered, it has no special meaning, there is no hidden key. I started this list when I realised that my project (JNI Cookbook) has to go through serious cleaning and I decided to tell people there are better books out there to […]

New font for the JNI Cookbook Redux cover

I am jumping between fonts from time to time. This time, the cover was changed a little bit – it uses now Source Code Pro. I think it has little bit more light feeling comparing to JetBrains Mono. I know it’s all just a matter of taste and some people prefer one font over the […]

Debugging Java with JNI on HPC machine

If you have worked on CLI based machines, where there is no way of running GUI debugger (e.g. TotalView) you probably know the struggle of debugging JNI based code.

Dealing with double _main in the Fortran code

From time to time it happens that you are forced to work with legacy code. This code might have _main already defined inside. This may happen in case you are trying to link two object files, both, defining _main function. There is hope! Let’s say we have a code (legacy one) And now, we are […]

Data backups – dedicated solution vs. home made server

Some years ago (~10) I was puzzled by the choice between dedicated backup machine (something like one describe here: QNAP TS-231P – rok i trzy fackupy później (na szczęście z happy endem)) vs. my own setup. There are advantages of dedicated backup solutions (so called NASes). These machines have close to zero configuration setup, look […]

Google Cloud Platform vs. recent stuff vs. refurbished machine

Recently, I have received “the very first time GCP client” offer from Google. I assume that all the people get this initial credit so they can test GCP based services. For me this was an obvious sign – how will it perform with Minecraft installed. To be honest, I was positively surprised. Setting everything up […]

The story of my new 47 PB hard drive

At some point, my Time Machine started to complain that there is no enough space to make a complete backup of my disk When I tried to figure out what was happening, it turned out that my $HOME was the place that occupied most of the space. I have tried to use typical approach to […]

Blade Runner

I’ve seen things you people wouldn’t believe. SVN repos so big they didn’t fit on SSD. I watched spaces glitter among the dark tabs of Python. All those moments will be lost in time, like tears in rain. Time to code using new hype.
