KLog is in GitHub

From time to time some people ask me to push my code to GitHub.

I must admit that I am confortable having KLog in the Savannah SVN. It works without any error, not a simngle problem since I started to use it many years ago, I also have some automations built at home, in my development environment… I though that it made no sense to migrate to GitHub.

Some days ago I decided to move my code to GitHub, I will probably keep Savannah and GitHub repositories until (hopefully) I finally get the same feeling with GitHub than Savannah.

I am doing this with the hope that some of you will be contributing to KLog easily if it is in GitHub and maybe KLog improves ­čÖé

If KLog development is mainly mine, it makes no sense to move to GitHub.

Anyway, you can find ttwo repositories:

https://github.com/ea4k/klog This repository hosts the code of KLog.

https://github.com/ea4k/klog-data This repository hosts files that are useful for KLog users or developers.

I hope this changes are useful for KLog!

KLog wiki

Many times, many people have asked for a manual, documentation, guide or similar.

A document explaining how to do something in particular or define some feature.

I admit, I prefer to code than to document but the manual could not wait any longer.

I have installed a Dokuwiki instance so we (yes, not only me, you also can support) write a manual for KLog.

You can find the manual in the KLog wiki.

If you want to contribute, register with your callsign and send me an email so I can change your profile to the editor profile… yes, it is not done automatically but I prefer to go this way to have the wiki full of spam in some days.

I will work on the wiki, trying to explain how to use KLog and I will also try to not releasing a new feature that is not explained I the Wiki.

How popular is KLog?

Maintaining a free software application where you simply code and upload your packages to the repositories makes very difficult to know if is there somebody out there using what you are producing.

I started KLog not for the users but for personal use and I keep that spirit, however the users of KLog are important as some of them are actively supporting KLog by reviewing, reporting bugs, providing suggestions, patchs, translations and I have even received some donations that I have used to pay for the hosting ­čÖé

On the other hand, I guess that the users that are actively saying “hello I am here” are just a small percentage.

Some days ago I realiced that maybe I could get some data from the Debian Popularity Contest and here is the data:

KLog is clearly not one of the most popular Debian packages. It is in the #36167 position out of 87160.

The interesting data comes when we compare with other hamradio logs as the results allow me to be more optimistic.

In the following graphic you can see a comparison of the different logs that Debian is providing by the number of installations. I am comparing just the last 5 years.

If we check for the most recent use of the log, KLog gets the first position mand it’s been the most used for a couple of years or so… or at least that is what we can see as KLog is the purple line.

With a two years span, we can see that people is installing cqrlog and maybe is people coming from xlog, that is clearly wining the contest but with a descendent tendence.

Again focusing on if the users installing the package are really using it, KLog is usually the winner.

It would be really interesting to have similar data coming from other sources, to see if one of the main differences of KLog (being native multiplatform) is noticed or not. How many macOS users does KLog have? How many Windows users does KLog have?

Anyway, these data are just for information and I hope it is funny for you to see what the popcon package is providing as it was for me to write this post.

Thank you for using KLog!
