Adventures & experiences in contemporary technology
What amazes me is how things can become more complicated over time. As long as you knew HTML, CSS and JavaScript, building a website was not as onerous as long as web browsers played ball with it. Since then, things have got easier to use but more complex at the same time. One example is WordPress: in the early days, themes were much simpler than they are now. The web also has got more insecure over time, and that adds to complexity as well. It sometimes feels as if there is a choice to make between ease of use and simplicity.
It is against that background that I reassessed the technology that I was using on my public transport and Irish history websites. The former used WordPress, while the latter used Drupal. The irony was that the simpler website was using the more complex platform, so the act of going simpler probably was not before time. Alternatives to WordPress were being surveyed for the first of the pair, but none had quite the flexibility, pervasiveness and ease of use that WordPress offers.
There is another approach that has been gaining notice recently. One part of this is the use of Markdown for web publishing. This is a simple and distraction-free plain text format that can be transformed into something more readable. It sees usage in blogs hosted on GitHub, but also facilitates the generation of static websites. The clutter is absent for those who have no need of the Gutenberg Editor on WordPress.
With the content written in Markdown, it can be fed to a static website generator like Hugo. Using defined templates and fixed assets like CSS together with images and other static files, it can slot the content into HTML files very speedily since it is written in the Go programming language. Once you get acclimatised, there are no folder structures that cannot be used, so you get full flexibility in how you build out your website. Sitemaps and RSS feeds can be built at the same time, both using the same input as the HTML files.
In a nutshell, it automates what once needed manual effort used a code editor or a visual web page editor. The use of HTML snippets and layouts means that there is no necessity for hand-coding content, like there was at the start of the web. It also helps that Bootstrap can be built in using Node, so that gives a basis for any styling. Then, SCSS can take care of things, giving even more automation.
Given that there is no database involved in any of this, the required information has to be stored somewhere, and neither the Markdown content nor the layout files contain all that is needed. The main site configuration is defined in a single TOML file, and you can have a single one of these for every publishing destination; I have development and production servers, which makes this a very handy feature. Otherwise, every Markdown file needs a YAML header where titles, template references, publishing status and other similar information gets defined. The layouts then are linked to their components, and control logic and other advanced functionality can be added too.
Because static files are being created, it does mean that site searching and commenting or contact pages cannot work they would on a dynamic web platform. Often, external services are plugged in using JavaScript. One that I use for contact forms is Getform.io. Then, Zapier has had its uses in using the RSS feed to tweet site updates on Twitter when new content gets added. Though I made different choices, Disqus can be used for comments and Algolia for site searching. Generally, though, you can find yourself needing to pay, particularly if you need to remove advertising or gain advanced features.
Some comments service providers offer open source self-hosted options, but I found these difficult to set up and ended up not offering commenting at all. That was after I tried out Cactus Comments only to find that it was not discriminating between pages, so it showed the same comments everywhere. There are numerous alternatives like Remark42, Hyvor Talk, Commento, FastComments, Utterances, Isso, Mouthful, Muut and HyperComments but trying them all out was too time-consuming for what commenting was worth to me. It also explains why some static websites even send readers to Twitter if they have something to say, though I have not followed this way of working.
For searching, I added a JavaScript/JSON self-hosted component to the transport website, and it works well. However, it adds to the size of what a browser needs to download. That is not a major issue for desktop browsers, but the situation with mobile browsers is such that it has a sizeable effect. Testing with PageSpeed and Lighthouse highlighted this, even if I left things as they are. The solution works well in any case.
One thing that I have yet to work out is how to edit or add content while away from home. Editing files using an SSH connection is as much a possibility as setting up a Hugo publishing setup on a laptop. After that, there is the question of using a tablet or phone, since content management systems make everything web based. These are points that I have yet to explore.
As is natural with a code-based solution, there is a learning curve with Hugo. Reading a book provided some orientation, and looking on the web resolved many conundrums. There is good documentation on the project website, while forum discussions turn up on many a web search. Following any research, there was next to nothing that could not be done in some way.
Migration of content takes some forethought and took quite a bit of time, though there was an opportunity to carry some housekeeping as well. The history website was small, so copying and pasting sufficed. For the transport website, I used Python to convert what was on the database into Markdown files before refining the result. That provided some automation, but left a lot of work to be done afterwards.
The results were satisfactory, and I like the associated simplicity and efficiency. That Hugo works so fast means that it can handle large websites, so it is scalable. The new Markdown method for content production is not problematical so far apart from the need to make it more portable, and it helps that I found a setup that works for me. This also avoids any potential dealbreakers that continued development of publishing platforms like WordPress or Drupal could bring. For the former, I hope to remain with the Classic Editor indefinitely, but now have another option in case things go too far.
Recently, I encountered the following kind of message when reading an Excel file into SAS using PROC IMPORT:
ERROR: Error opening XLSX file -> xxx-.xlsx . It is either not an Excel spreadsheet or it is damaged. Error code=8000101D
Requested Input File Is Invalid
ERROR: Import unsuccessful. See SAS Log for details.
Naturally, thoughts arise regarding the state of the Excel file when you see a message like this but that was not the case because the file opened successfully in Excel and looked OK to me. After searching on the web, I found that it was a file permissions issue. The actual environment that I was using at the time was entimICE and I had forgotten to set up a link that granted read access to the file. Once that was added, the problem got resolved. In other systems, checking on file system permissions is needed even if the message seems to suggest that you are experiencing a file integrity problem.
Earlier in the year, I upgraded my monitor to a 34-inch widescreen Iiyama XUB3493WQSU. At the time, I was in wonderment at what I was doing even if I have grown used to it now. For one thing, it made the onscreen text too small so I ended up having to scale things up in both Linux and Windows. The former proved to be more malleable than the latter and that impression also applies to the main subject of this piece.
What I also found is that I needed to scale the user interface font sizes within Adobe Lightroom Classic running within a Windows virtual machine on VirtualBox. That can be done by going to Edit > Preferences through the menus and then going to the Interface tab in the dialogue box that appears where you can change the Font Size setting using the dropdown menu and confirm changes using the OK button.
However, the range of options is limited. Medium appears to be the default setting while the others include Small, Large, Larger and Largest. Large scales by 150%, Larger by 200% and Largest by 250%. Of these, Large was the setting that I chose though it always felt too big to me.
Out of curiosity, I decided to probe further only to find extra possibilities that could be selected by direct editing of a configuration file. This file can be found in C:\Users\[user account]\AppData\Roaming\Adobe\Lightroom\Preferences and is called Lightroom Classic CC 7 Preferences.agprefs. In there, you need to find the line containing AgPanel_baseFontSize and change the value enclosed within quotes and save the file. Taking a backup beforehand is wise even if the modification is not a major one.
The available choices are scale125, scale140, scale150, scale175, scale180, scale200 and scale250. Some of these may be recognisable as those available through the Lightroom Classic user interface. In my case, I chose the first on the list so the line in the configuration file became:
AgPanel_baseFontSize="scale125"
There may be good reasons for the additional options not being available through the user interface but things are working out OK for me for now. It is another tweak that helps me to get used to the larger screen size and its higher resolution.
While there are many tools that will build XML site maps, there is some satisfaction to be had in creating your own. This is in spite of there being a multitude of search engine optimisation plugins for content management systems like WordPress or what is built into static site generators like Hugo. Sometimes, building your own allows for added simplicity and that is shared with recent efforts in WordPress theme development.
The sitemap XML protocol is simple enough to offer a short coding project. The basis was what Hugo generates and I used Python to create the XML files. The only libraries that I needed were configparser, SQLAlchemy and pandas. the first two of these allowed databases to be queried and the last on the list was used for data processing. Otherwise, it was a case of using what is built into the Python language like file writing and looping.
Once the scripts were ready, they could be uploaded to web servers and executed by scheduled jobs using CRON to keep things up to date. along the way, I also uncovered a way to publicise the locations of the sitemap files to search engine bots using robots.txt. The structure of the instruction is the following:
User-agent: *
Sitemap: sitemap.xml
This means that it announces to all bots the location of the sitemap file. In my case, I always included the full URL for the XML file and that clearly varies by website location.
In recent days, I have been trying to get Windows 11 to run smoothly within a VirtualBox virtual machine, and there has been a lot of experimentation along the way. This was to eradicate intermittent freezes that escalated CPU usage and necessitated hard restarts. If I was to use Windows 11 as a long-term replacement for Windows 10, these needed to go.
An internet search showed that others faced the same predicament but a range of proposed solutions did nothing for me. The suggestion of enabling 3D graphics capability did nothing but produce a black screen at startup time so that was not a runner. It might have been the combination of underlying graphics hardware and the drivers on my Linux Mint machine that hindered me when it helped others.
In the end, a look at the bug tracker for Windows guest operating systems running on VirtualBox sent me in another direction. The Paravirtualisation interface also may have caused issues with Windows 10 virtual machines since these were all set to KVM. Doing the same for Windows 11 seems to have stopped the freezing behaviour so far. It meant going to the virtual machine settings, navigating to System > Acceleration and changing the dropdown menu value from Default to KVM before clicking on the OK button.
Before that, I have been blaming the newness of VirtualBox 7 (it is best not to expect too much of a fresh release bringing such major changes) and even the way that I installed Windows 11 using the streamlined installation or licensing issues. Now that things are going better, it may have been a lesson from Windows 10 that I had forgotten. The EFI, Secure Boot and TPM 2.0 requirements of Windows 11 also blindsided me, especially given the long wait for VirtualBox to add such compatibility, but that is behind me at this stage.
Windows 11 is not perfect but Start11 makes it usable and the October 2025 expiry for Windows 10 also focuses my mind. It is time to move over for sake of future-proofing if nothing else. In time, we may get a better operating system as Windows 11 matures and some minds surely are thinking of a “Windows 12”. However things go, it may be that we get to a point where something vintage in the nature of Windows XP, Windows 7 or Windows 10 appears. Those older versions of Windows became like old gold during their lives.
For reasons that I cannot recall now, I installed the Hugo static website generator on my Linux system and web servers using Homebrew. The only reason that I suggest is that it might have been a way to get the latest version at the time since Linux Mint only does major changes every two years, keeping it in line with long-term support editions of Ubuntu.
When Homebrew was installed, it changed the lookup path for command line executables by adding the following line to my .bashrc file:
eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"
This executed the following lines:
export HOMEBREW_PREFIX="/home/linuxbrew/.linuxbrew";
export HOMEBREW_CELLAR="/home/linuxbrew/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/linuxbrew/.linuxbrew/Homebrew";
export PATH="/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin${PATH+:$PATH}";
export MANPATH="/home/linuxbrew/.linuxbrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="/home/linuxbrew/.linuxbrew/share/info:${INFOPATH:-}";
While the result suits Homebrew, it changed the setup of Python and its packages on my system. Eventually, this had undesirable consequences like messing up how Spyder started so I wanted to change this. There are other things that I have automated using Python and these were not working either.
One way that I have seen suggested is to execute the following command but I cannot vouch for this:
brew unlink python
What I did was to comment out the offending line in .bashrc and replace it with the following:
export PATH="$PATH:/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin"
export HOMEBREW_PREFIX="/home/linuxbrew/.linuxbrew";
export HOMEBREW_CELLAR="/home/linuxbrew/.linuxbrew/Cellar";
export HOMEBREW_REPOSITORY="/home/linuxbrew/.linuxbrew/Homebrew";
export MANPATH="/home/linuxbrew/.linuxbrew/share/man${MANPATH+:$MANPATH}:";
export INFOPATH="${INFOPATH:-}/home/linuxbrew/.linuxbrew/share/info";
The first of these adds the Homebrew paths to the end of the PATH variable instead of the start of the same as was the case before. This means that system folders get searched for executable files before the Homebrew ones. It also means that Python packages are loaded from my user area and not the Homebrew one as was the case under its own terms. There are other things to remember with Python packages such as not having a version installed at the system level and another at the user one since these will conflict with one another.
So far, the result of the Homebrew changes is not unsatisfactory and I will watch for any rough edges that need addressing. If something comes up, then I will set things up in another way.
One thing that I have been doing across my websites is to move away from using Google web fonts using the advice on the Switching.Software website. While I have looked at free web font directories like 1001 Free Fonts or DaFont, they do not have the full range of bolding and character sets that I desire so I opted instead for the Google Webfonts Helper website. That not only offered copies of what Google has but also created a portion of CSS that I could add to a stylesheet on a website, making things more streamlined. At the same time, I also took the opportunity to change some of the fonts that were being used for sake of added variety. Open Sans is good but there are other acceptable sans-serif options like Mulish or Nunita as well, so these got used.
Earlier this year, I changed over two websites from dynamic versions using content management systems to static ones by using Hugo to build them from Markdown files. That meant that I needed to look at the editing of MarkDown even if it is a fairly simple file format. For one thing, Grammarly can be incorporated into WordPress so I did not want to lose something like that.
The latter point meant that I was steered away from plain text editors. Otherwise, there are online ones like StackEdit and Dillinger but the Firefox Grammarly plugin only appears to work on the first of these, and even then only partially in my experience. Dillinger does offer connections to online file storage providers like Google, Dropbox and OneDrive but I wanted to store files on my desktop for upload to a web server. It also works with Github but I prefer to use another web hosting provider.
There are various specialised MarkDown editors for desktop usage like Typora, ReText, Formiko or Ghostwriter but I chose none of these. My actual choice may surprise many: it was Visual Studio Code. The availability of a Grammarly plug-in was what swayed it for me even if it did need to be switched on for MarkDown files. In many ways, it does work as smoothly as elsewhere because it gets fooled by links and other code-like pieces of text. Also, having the added ability to add words to a custom dictionary would be ideal. Some rule overriding is available but I am not sure that everything is covered even if the list of options is lengthy. Some time is needed to inspect all of them before I proceed any further. Thus far, things are working well enough for me.
Since I created a bespoke theme for this site, I have been tweaking things as I go. The basis came from the WordPress Theme Developer Handbook, which gave me a simpler starting point shorn of all sorts of complexity that is encountered with other themes. Naturally, this means that there are little rough edges that need tidying over time.
One of these is dealing with errors on the site like when content is not found. This could be a wrong address or a search query that finds no matching posts. When that happens, there is a redirection to the home page using some simple JavaScript within the loop fallback code enclosed within script start and end tags (including the whole code triggers the action from this post so it cannot be shown here):
location.href="[blog home page ]";
The bloginfo function can be used with the url keyword to find the home page so this does not get hard coded. For now, this works so long as JavaScript is enabled but a more robust approach may come in time. It is not possible to do a PHP redirect because of the nature of HTTP: when headers have been sent, it is not possible to do server redirects. At this stage, things become client side so using JavaScript is one way to go instead.
This is the second post on Ansible following my main system’s upgrade to Linux Mint 21. Then, I manually ran some Ansible playbooks only to spot messages that I had not noticed before. Here, I discuss two messages issued because of an issue with an inventory file, which is where one defines lists of servers against which playbooks are executed. The default is called hosts and is located at /etc/ansible but the system upgrade had renamed the existing one so Ansible could not find it. The solution was to take a copy and put somewhere safer. Then, I needed to add the location of the new file to the affected ansible-playbook commands using the following construct:
ansible-playbook [playbook path] -i [inventory file path]
Before I did this, I was seeing messages including the text “Could not match supplied host pattern” or others with the following text:
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
The cause was the same in each case and attending to the inventory file got rid of the unwanted messages. The new file also should not be affected by system upgrades in the future.
