About this site
These are just some thoughts about this and that in the software industry, and elsewhere, by a long-time coder/hacker.
Except - for demonstration purposes i have added Disqus comments to an article showing how to enable disqus in stbl. If you open this article, disqus will track you, add cookies and try to make profit from that information. I have also added IntenseDebate comments to one article, where I show how to enable that for stbl. This will also add some tracking. IntenseDebate is a free service from the company behind Wordpress.

I am a Norwegian expat, currently living in a small village in Bulgaria with my dogs and my computers.
Over the years I have worked with many programming languages. My preferred programming language for the past 20 years is C++. The code I write for my own projects usually runs on Linux, Windows and macOS.
Unlike many software developers, I have never had any desire to "move on" in my career and become a manager. I guess I love solving problems and writing code too much. I have worked in tiny startups, medium size startups, and for two years as a senior C++ developer in a giant software company. I have declined senior staff positions in two of the largest software / IT companies in the world. I treasure my personal and professional freedom more.
I am not a "Full Stack" or "Front End" or "Back End" developer. I have a wide surface of experience that makes it hard to put a simple label on it. I know how to make web sites, of course. I also know how to make native GUI applications for Linux, Windows, macOS, Android and IOS. I am best known for some of the servers and libraries I have written (most for the War FTP Daemon I guess). I have spent months optimizing a new thread-pool written in portable C++ for a sever application used by almost all medium to large companies in the world. I have written - and optimized - C++ database libraries, using sqlite, Microsoft SQL Server, MySQL, and Postgres. Even Oracle (although I prefer not to talk about that). I have written hundreds of command-line programs.
Today lot's of people are embracing micro-services and REST. I am familiar with both. That is; splitting complex functionality into micro-services (which is hard to get right), and making components talk to each others. The talking part with REST I have used for quite some time - both on the client end and at the server side. I have also played with Googles more efficient alternative, grpc. And before that I used Zeroc's ICE and Corba. I have even used Sun's legacy RPC protocol over UDP for client/server communication.
Besides being a senior software architect / developer, I have been:
- IT consultant
- IT Security consultant
- IT technician (that's where it all started)
- Sales manager, hardware, software and services (I had an insane sales-score, but I was not happy)
- Journalist (at two local radios in Norway)
- Radio technician (at three local radios in Norway)
- Manager for a team of software developers (I sucked at it!)
- Flipping burgers at KFC
- Bouncer at two night clubs in Norway
- Disk Jockey
- Manager for a night club
- Preschool teacher
- Assistant at a large institution for mentally disabled people
Programming languages I have used professionally over the past 5 years:
- C# (.net Core)
- Objective C
- Java (I hate it!)
- php (You will find my name in the C source code for one of the standard libraries)
Operating systems I have written software for
- Linux (since 1997)
- Windows (from 3.0 to 10)
- QNX (3 and 4)
- SCO Unix
- Interactive Unix
- Digital VAX
C++ technologies and libraries I use a lot today
- Modern C++ 11, 14, 17
- boost libraries
- QT (both widgets and QML)
Other programs / technologies I use often these days
- Visual Studio Code
- Visual Studio Professional
- Android Studio
- Wireshark (They used to use my adns library port for their Windows version)
Some things I have designed and implemented
- nginx-swarm-proxy - Docker container to use stock Nginx as an adaptable front-end for Docker Swarm services

- whid - "What Have I Done" - Time Tracker for Freelancers and Individual Contractors
- stbl (the software that I use to build this site)
- restc-cpp - A small and very fast REST HTTP[S] client library in C++14
- shinysocks - A small, ultra-fast SOCKS proxy server.

- SmsRelay - Android app that forwards SMS messages to XMPP
- FTP Server (War FTP Daemon)
- vUbercool - a http/dns server to host 1 billion websites on a laptop
- HTMGen32 - The software I used to build my homepages in 1997
- WarCMS - Full featured CMS / Social network application in php - later with a core engine in C++, interacting with the PHP code over object oriented RPC (ICE).
- VikingGTD - Simple "Getting Things Done" App for Android
- WarLib - A tiny C++ library providing some basic building blocks to modern C++ applications; like logging, threadpool, tasks, etc.
- wfde - A Full featured modern C++ library implementing the server side FTP protocol (and HTTP).

- Numerous small utilities and libraries for Linux and Windows
- A commercial APN (Apple Push) gateway / microservice

- NNTP server (just for fun)
- NFS server (I needed it)
- Basic interpreter (just for fun)
- Spread Sheet (using curses from lack of a windowing system - just for fun)
- Website for a Norwegian energy provider - with aggregated data from hundred of thousands of on-line power meters, broken down to house holds, buildings, campus, city, corporation or enterprise. It provided customers with the ability to generate reports from any time-period and any selection of facilities - usually - in seconds. (This was before Big Data came on the radar - I did it using MySQL, C++, PHP and some hard thinking)
- Shipyards management software (an overall system that planned and scheduled repairs of ships, including naval ships, and integrated deeply with the organizations other IT systems)
- Truck yard management software (for a while used by most of the Volvo truck yards in Norway)

- DaRe - Database replication utility
- ssft- Simple and secure file transfers over SSL. (Like scp, but designed to be more constrained and secure)
- WarSetup - Windows installer. Initially written because Microsoft's setup library had too many bugs, later rewritten to use WIX conveniently with advanced options from a very simple GUI interface.
- War Support - A software support site written in php with issue tracking, version tracking, downloads, etc.
- Full featured Word Processor (network distributed architecture for QNX, Interactive Unix and SCO Unix, running on terminal, X/Motif and the QNX graphical UI (at that time)). (We were actually two developers on this project, so I can only claim 50% credit).

- HTTP (servers and clients)
- NNTP (server)
- SMTP (clients)

General Internet servers I have implemented singlehandedly from scratch
- FTP server
- HTTP Server
- DNS server
- NFS server
- NNTP (usenet) server
