Welcome ... I'm Kristof

I've been a passionate software developer for a very long time ... now I'm a tech-savvy IT manager and tinker with things like this blog in my free time ;)

Developing software never lets you go. It's a creative passion and for me it's the web that has fascinated me for almost 30 years.

My latest stuff is below and here is more about me. Meet me @kiko@indieweb.social.

VS Code on the Web

Multiple ways to work with Visual Studio Code online

For most of the years I have been in the IT industry, I have worked with the “fat” Visual Studio from Microsoft. Fat in terms of features, for sure, but also in size and load times. It made no sense to use an other IDE, while developing software with VB.NET/C#. But with the advent of Node.JS JavaScript, so far only known as a scripting language for web pages, outgrew itself and became a serious competitor to established languages.

In 2012 Adobe came out with Brackets, a lightweight IDE for developing web applications, written with the very same tech stack: HTML, CSS and JavaScript! Based on the Chromium Embedded Framework, it felt like a normal application! Mind blowing…

In 2015 there was a new kid in town: Visual Studio Code (VS Code), of all things from … Microsoft. During this time, the Redmond-based company had finally jumped on the open source bandwagon and perhaps they saw that Adobe was doing some things right on the IDE market with Brackets (but also some things wrong) and you didn’t want to miss the chance to engage the open source community.

The speed with which VS Code passed other IDE’s in the developer favor was quite amazing, due to the fact that the source code was openly available on GitHub and the developers in Switzerland released a new version every damn month.

What was exciting for me was the question of how long it would take for someone to make this IDE based on web technology available online, i.e. in a browser. It took until 2021…

Lightroom Presets

Croatian Presets for Lightroom

Staying in Croatia is always a joy, in summer but also in winter. I’m on this side of the Adriatic sea almost every year. In summer you have a pleasant heat, inviting you to swim, and sometimes too many tourists. In winter you have the magic light and space to enjoy the country.

Over the past years a have created some presets to bring my images, shot in Croatia, to a next level of beauty and I want to share them with you in this post.

The Last Image Gallery...

... you have to deal with: Spotlight

In the last decade(s) I have seen and tried many image galleries and lightboxes for showing images or groups of images. Depending on your needs, you can choose out of trillions of solutions, for every JS framework or vanilla JS, in every flavour, size and color. With many of them, however, you reach the limits quite quickly. Be it in terms of visual adaptability, extensibility or implementation. Customization cost time and nerves, especially if the respective library has structural weaknesses.

However, from today on, I don’t need to look for a suitable solution for my next project, because I found one that leaves absolutely none of my wishes unfulfillede: Spotlight by Nextapps from Berlin, Germany.


To make it clear: this is not a paid advertising text or something like that. That wouldn’t make sense either, because Spotlight is Open Source (Apache 2.0 License) and its code is availabel at GitHub. I’m just thrilled with the work of the developers.

Problems with post asset files in Hexo and a solution approach

A while ago I wrote about Automatic Duplicate Image Shadow and used indiepen for showing the result of my efforts.

indiepen is a solution for showing code samples without the need of a code sharing platform, like codepen. Just reference a index.html, main.js and styles.css from wherever you want and indiepen is wrapping it with a neat viewer inside an IFrame.

I did it quick and dirty first (sample files in a static folder) and now it was the time to do it right: place the sample files in a subfolder of the post in my Hexo-driven blog solution, in order to reference it from there AND have the possibility to call it directly via ./post/my-post/sample.

The key to achive that in Hexo is the configuration option post_asset_folder: true, which generates a subfolder for all assets with the same name as the post.

|- _posts
|- my-blog-post
|- my-first-asset.jpg
|- my-second-asset.jpg
|- my-blog-post.md

My idea regarding the indiepen files was having a subfolder for each indiepen in the post asset folder:

|- _posts
|- my-blog-post
|- my-first-asset.jpg
|- my-second-asset.jpg
NEW |- sample
NEW |- index.html
NEW |- main.js
NEW |- styles.css
|- my-blog-post.md

Run hexo generate, check that the indiepen was showing up properly and I thought I was done. Wrong … after commiting my changes to Github, where my blog is living, and checking my RSS feed a while after, I saw this:

Photo Workflow Re-Thought

To be honest: many of my posts here on kiko.io are written just for me. To internalize things by writing them down and to give my future me the chance to look up something I did in the past. So is this post. Future me: Don’t forget the following!

I while ago I was on a trip, shooting a lot of photographs and on my way back home I had three 32GB SD cards full with great photos. I was working with my old Nikon D7000, which has 2 card slots and I just took them out, when one of the cards was full. Worked fine for several years … but after this trip, one of the cards, full with RAW files and wonderful photos, w-a-s   N-O-T   r-e-a-d-a-b-l-e   a-n-y-m-o-r-e … f***! I saved myself the backup and now had to suffer over my carelessness.

I thought about some fancy and expensive backup solutions for professional photographers, but realized after a while, that I already had the equipment to achieve everything I needed and I could even use it to improve my general workflow.

In this post, I want to show you, what my workflow looks like today and how yours might benefit from my mistake.

Application-Specific Links on Windows 10

What works and what we still have to wait for

While reading the Chris Coyier’s post Application-Specific Links the other day, I realized what has been bugging me for a long time now: a proper solution for openening a certain URL in a modern Web App.

Since the beginning of the digital age (feels like that), we have files associated to a certain application, installed on our machine, regardless if its running Windows, iOS, OS/2 or whatever. We have learned that well and no one questions it … but … the IT world keeps on turning and today we are not only talking about files, but about links.

Many modern applications are written with Web technologies, thanks to cross platform frameworks like Electron. Some of them are real apps for working on things, like the famous editor Visual Studio Code, and some are mirroring their online services in a desktop app only, like Slack or Notion. However, the latter have the problem how to deal with links to their online services. When a user is sent a link and has become accustomed to using the desktop app, it won’t open in the app as he clicks on it, but in his default browser. The question is, how to associate not only files, but links with certain desktop apps?

Pattern for dynamic Hexo pages

Set up pages with dynamic data easily

Hexo is a great SSG platform for blogging. Just write your Markdown beneath some Frontmatter meta data, run hexo generate and publish the results to a web server.

But at some point you may want to process different data from internal or external sources and integrate it into your blog. Hexo doesn’t support this out of the box, but has a powerful feature called Generator, which helps you to achieve your goal. The following is a sample and pattern of how to implement this.

The starting point of my example is the requirement to display several elements of the same type on a dynamic page, but you can of course adapt the example according to your needs.
