Miksi?

Enää kaikissa Linux-distribuutioissa ei tule automaattisesti vi tai vim-editoria mukana. Siispä asennetaan se itse.

Miten?

apt install vim

Entä jos asennus ei toimi suoraan?

Kokeile putsata mahdolliset “roskat” pakettijärjestelmästä ensin kolmella komennolla:

sudo apt-get remove vim-common 

sudo apt-get clean && sudo apt-get purge 

sudo apt-get update && sudo apt-get install vim

En pääse ulos vim:stä!

Jos “hukut” vim:iin kun olet ajanut ohjelman, eli et pääse editorista pois, muista aina seuraava komento:

:q!

(kaksoispiste, pieni q, ja huutomerkki perään – sitten paina enter näppäimistöltä) – pitäisi toimia. Palaat shellin komentokehotteeseen.

WordPress 5.4 Beta 3

I had  several hundred articles  on Jukkasoft. It had been a journey of tad less than 11 years. User counts were up, visitors booming. My relative boom!

Then I wanted to actually delve deep into WordPress development. As I am a wetware engineer, going into tech is in itself rewarding. It’s new territory to conquer. Writing code and writing articles actually both work as mental exercise.

Nerd Sniping? Yes. Useful? Hope so!

Plugins are the sauce of a WordPress engine. Plugins have been used throughout the known universe, both time- and space-wise, to make most everything.

A WordPress site is composed of few basic ingredients:

• database
• WP engine (PHP code)
• an active theme
• plugins
• a configuration

Desired qualities of Plugins

Neat plugins make an improvement that is understandable, (somewhat) necessary, useful to at least a good bunch of people (one will do, for starters), and easy to use.

The freedom to experiment is wonderful. There’s probably not a plugin that would be useless, for the person who writes it. I haven’t written any plugins, yet. So the first ones will be pretty simple.

I do have a dream of a plugin, called ‘Diamond’ (what an original project name!?)

The Diamond plugin would allow to experiment with simple tinkerings, kind of like A/B test the effects of very simple changes to the blog; a change in a WordPress theme being used; perhaps just as simple as a background color, text style or similar.

The idea is that you could check the numbers, whether the changes in your blog’s visitors is positive. Increase in visitor counts and certain similarly headed statistics would tell you indirectly that at least you didn’t screw up!

I believe people vote by their true online actions. If the blog is not visited a lot, it simply doesn’t yet contain interesting stuff, OR it has some impediment that makes the content hard to access.

WordPress plugins explained

WordPress plugin dev rules of thumb

• use ‘return’ within the plugin PHP code
• do not ‘print’ content from a plugin
• register the plugin’s entry points
• use comment section to provide metadata for WordPress (it will understand your plugin better)

Gradient ascenter

• ascenter => we inverse the direction
• typically Scrum has burndown visualization
• developers are “relaxing towards a zero”, which may not be good
• in Gradient ascension, the (Gradient descenter’s) “cost function” is still applicable; see machine learning and Gradient Descent
• ..but as it’s going towards up (ascending), interesting idea of Project direction (compass) meaning arises also!
• without proper direction, we might end up in wrong valley
• Gradient ascenter was my ad-hoc term for the idea of a Software teamwork done like rock climbing: leave no one behind!
• safety net
• ascent happens only so that no one can be too far ahead (or too far left behind)
• psychological safety in a software project
• implementation: more to come!
