a tumblelog
week 13, 2019

More Sassy

Converted the CSS of my main blog to Sass, a CSS extension language. Fixed a few small issues in the layout and even found an unclosed a element (oops). Also created a Makefile, similar to the one I use for this blog. For more information on the latter, see Create a static tumblelog with Perl.

The Swarm

Half past midnight I started in The Swarm by Frank Schätzing. This novel was recommended to me by my aunt Renate. She also recommended Ragdoll by Daniel Cole to me, which I finished earlier this month.

Google Search Console

After midnight I added Plurrrr to Google's Search Console. Right now it's processing data and I have to check again in a few days. I want to keep track of how well this site behaves on the Internet and if it attracts readers. Even though it's mostly a public notebook I do like to see other people visiting and hopefully enjoying this site.

Stylesheet made easy

I converted the stylesheet for this blog to Sass, a CSS extension language. This makes it easier to maintain the stylesheet and create other ones using different color schemes.

I generate the style sheet using:

sass --sourcemap=none \
     -t compressed \
     soothe.scss styles/soothe.css

The --sourcemap=none prevents /*# */ from being added to the end of the generated CSS file.

Holy Ghost

Two past twelve AM I finished Holy Ghost (A Virgil Flowers Novel) by John Sandford. It was an excellent read, recommended if you like mystery.

As it was already past midnight I blog this under a new day.

Emacs Color Themes

In the evening I browsed some Emacs color themes. My current theme is Charcoal Black, which I like a lot. I checked out once more an Emacs theme gallery, where I found last week Jason Milkin's Soothe theme that I used to pick the colors for this blog from. And I also checked out Emacs Themes and Owain Lewis' Emacs Themes.

From the latter page I like Brin, Graham, and Junio a lot. Maybe next month I try to make my own theme just like I did many years ago for Textpad, an editor running on Microsoft Windows. I probably am going to use Jason Milkin's Emacs Theme Editor.

First bug found

Found my first mistake in the tumblelog Perl program I wrote: I accidentally counted entries as days to limit the number of content on the main page. Since a day can have multiple entries this resulted in content already being moved off the front page. Easy fix: move the test outside of the innermost loop.

Major rewrite

Just finished a major rewrite of; the Perl program that generates the pages of this microblog. It now makes pages for each day besides week overviews.


Reading the JSON Feed Version 1 specification. Right now, I think it's overkill to add a JSON feed to this microblog, but I am considering to add such a feed to the blog on my personal website.

To find or not to find

Why not use File::Find and do it all in perl?

asked Reddit user raevnos in response to my submission Driving a Perl script via find. To which I replied:

Good question, which the article should have answered. In my case I wanted to use find to drive the Perl program because I consider it slightly easier to edit and fix on the cli than in a program. Also, I wanted to learn a bit more about find and the speed difference between \; and \+. Finally, I can imagine that this solution is faster, and can be modified easier (with cli tools) by other (non-Perl) users.

Viewport units: vw, vh, vmin, vmax

I have been working on a login form for mobile users the past days and this article on viewport units has been very helpfull.

A little wider now

On screens 480 pixels and wider this blog is now 480 pixels wide instead of 320 pixels. I used a CSS @media Rule as follows:

@media screen
    and (max-width: 479px) {
    #tl-page {
        width: 320px;

Markdown Cheatsheet

Since I am about to post an image I had to look up the syntax for embedding an image using Markdown. So I Googled and found a Markdown Cheatsheet which gave me the answer.

Image Test: Yellow Chrysanthemum flowers

Background image with opacity in CSS

I just used the following CSS code to create a body background image with opacity for work:

body::before {
  background-image: url("img.jpg");
  background-size: cover;
  content: "";
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -2;
  opacity: 0.25;

Code comes from a well written article by Chris Love. Thanks!.

First Post

Back in 2003 I started my first microblog. This is a continuation of this blog and it runs aside my new full blog. This tumblelog will be dedicated to short posts, notes, quotes, and link dumps.

I wrote the code that generates this static site in Perl and it will be soon available via my GitHub page.

The current layout is heavily based on the well-known tumblelog Anarchaia. Colors where picked from the Emacs Soothe theme by Jason Milkins.

What the Plurrrrrr!

Years ago I bought the domain Yesterday I started coding, the program that generates the static pages for this site, planning to use this domain. And today I noticed that I had let go this domain some time ago. So I just added one additional r. And hurray, was available.

A Simple Makefile Tutorial

Used a simple makefile tutorial to create a small Makefile that generates the pages for this site via and uploads the local version of this site using rsync.

How to manipulate CSS colors with JavaScript

This write up on manipulating CSS colors has a great intro on the two different color models CSS uses: RGB and HSL.

Installing the CommonMark Perl module on Ubuntu 18.10

Building Virtual Machine Labs

I downloaded the hands-on guide Building Virtual Machine Labs by Tony Robinson, which can be downloaded for free as PDF. I plan to start working through this guide starting next week.
