Minimal Accessible Tooltip
Please! Stop with the mobile web sites! If you are using browser agent strings to change your CSS/layout don't! Use responsive CSS instead. There are other situations when you need a small window and devices that have a small screen where your web site does not work.
After quite a few years of waiting, I finally got my Librem 5 phone. I am now using it as my primary phone… using my work phone as a back-up. Here are the issues and whether I think using it as a primary phone is a good idea so far.
If you are wanting to apply accessibility labels onto an image, here are the label (
aria-label) priorities (highest first):
aria description does not get read out if there is no other label attributes. (Tested on Windows, NVDA, and Firefox and Edge).
Javscript is missing functions to format dates in some common formats, such datetime-local inputs and RFC 5322 (email dates) in a non-obsolete way. While Date.toUTCString() is close, the timezone is now obsolete (though it is handy for HTTP Date and other such headers). Here's the basic functions to get the right formats
When changing a reworked menu to have accordian animations, I came to the realisation that I have been missing a big issue when using
transition animations — accessibility. I detail a simple fix in this article.
Turns out screen readers really don't like you playing with the
display CSS property on lists, for example to change it to an inline list — it will cause lists items to be read like a paragraph. Here's how to do without upsetting the screen readers.
I have started experimenting with low power wide area networks (LP-WAN) in New Zealand using a u-blox SARA-R410-02B. Here is what I have experimented with so far.
I have recently been dealing with parsing binary data packets from various sources, and have published two NPM libraries from it: binary-decoder and sbd-direct-ip. Here's how they came to be.
I started developing my trap-watch project on an ESP32-CAM using the ESP IDF. Here is the newbie difficulties I ran into.
Developing ESP-IDF components I thought it would be great if I could make a command to open all the files for a component at once. What a rabbit hole it was. Here is how I did it.
Making a script parse arugments in Bash took me way too long last time I did it, so here is a nice full example of how to do it using
I have recently started trapping some introduced predators around my local area and have had baits and pre-feed disappear with nothing to show for it, so I decided to get sparky and see if I could catch the culprit in the act.
Finally got around to creating a SLD style for GeoServer to display bathymetric contour lines using the GEBCO gridded bathymetric data. Here's how.
I am often trying to find more space on my hard drives and found today my own docker containers wasting space thanks to ! Here's how I fixed it.
Upon recently trying Deezer again, I found their web app ate all my memory when running in Firefox, so I decided to see if I could find out why. I got as far as memory-file-data/string and Blobs. Here's how.
In a culmination of litter surveys and litter picks, linked data and data exploration, and remoteStorage and ActivityPub, I have created a web-based litter pick/survey app that I hope will allow federated citizen science.
My latest litter pick target was Hoe Stream and the White Rose Lane Local Nature Reserve. Here's how it went.
I just created a Gitlab CI job to create a release with information from a CHANGELOG.md file for some of my projects. Here's how I did it.
I noticed something strange happening during build process during a multi-tasking bug fix. Turns out I was using Gitlab CI's caching incorrectly. I should have been using artifacts. Here's what I saw.
As a birthday treat, I took the day off work to try out my electronerised litter picker. Here's how it went.
In preparation for a day of litter picking, I finally got round to a project idea - attaching a camera to a litter picker to record it all. Here's what I did.
I finally started implementing UI testing on first-draft using WebdriverIO. While writing tests was easy, getting the tests running was a little more difficult. Here is how I did it.
Hooray! My new blog is live! Based on Sapper, using MongoDB and eventually ActivityPub and ActivityStreams, it will be my federated posting hub to the world.
Creating this new blog, I wanted to make sure there was no metadata data leaking personal information. Here's how I removed all the metadata tags except the ones I wanted from my photos.
tmux for your terminal multiplexer but want an easy to reattach to a session? Here's a small bash script to do it.
Here's how to help your readers save time by making your post's shell commands easy to select and copy - with a simple CSS property.
Making my new blog, I didn't initially set the published dates to be native dates in the database. Here what I did to change them …and do all the upgrades I needed.
I recently needed to test that some Vue components were creating the correct HTML. To do this, I decided to create snapshots of Object representations of the rendered HTML.
HTML5 number inputs aren't useful, but tel inputs, have all the power
I decided to look into the extortion emails I have been getting and wrote a small script to extract the bitcoin addresses that have been used.
As part of my pledge not to upgrade, I decided to repair two of my failing mice instead of replacing them with a brand new model (as tempting as it was). Here's what I did.
To handle the manage the amounts of images we seem to be producing on our trips, I created a few simple scripts to do a few tasks that I found myself doing constantly.
As Canons files are name IMGXXXX.JPG, where XXXX is a one up number, and everytime you start a new folder (good for a new place) on the 450D, it starts from 1, you end up with quite a few duplicate names. To get around this, I add the folder identifier to the name using this simple bash script. The script can also make web-ready versions of the image, but I now use the next script for that.
# Goes through folders and renames images depending on folder name and # makes a web ready version of the image rF= num=1 chars=XX cD=`pwd` ##find . -type f -name '*.*' -print0 | while IFS= read -r -d '' file; do echo "$@" | while IFS= read -r -d '~' d; do #for d in "$@"; do if [ -f "$d" ]; then dN=`basename "$d"` convert -auto-orient -resize 1100x1100 -quality 80 "$d" "$rF/$dN" echo resized $d - $rF/$dN elif [ -d "$d" ]; then p='' dN=`basename "$d"` if (echo $dN | grep -q '..._....'); then p=`echo $dN | sed -re 's/(...)_....\/?/\1/'` p="G$p" echo Folder $d from G15 - p = $p elif (echo $dN | grep -q '...CANON'); then p=`echo $dN | sed -re 's/(...)CANON\/?/\1/'` p="4$p" echo Folder $d from 450D - p = $p elif (echo $dN | grep -q '....CANON'); then p=`echo $dN | sed -re 's/(....)CANON\/?/\1/'` echo Folder $d from a labelled Canon device - p = $p else p=$chars$((num++)) echo Unknown folder - p = $p fi if [ "$p" ]; then # Move into folder cd "$d" # Rename files for f in `ls ???_????.??? 2>/dev/null`; do n=`echo $f | sed -re "s/(...)(_....\....)/\1_$p\2/"` mv $f $n done if [ "$rF" ]; then # Make sure resized folder exists if [ ! -d $rF ]; then mkdir $rF fi # Make web version of image for f in *.JPG; do convert -auto-orient -resize 1100x1100 -quality 80 "$f" "$rF/$f" echo resized "$f" done fi # Move back into original folder cd "$cD" echo finished folder $d else echo Uknown type of folder - ignoring fi else echo Not sure what to do with $d, ignoring. fi done
I currently keep a directory of copied web-ready images so that it can synced with the server holding my blog whenever I get a chance. This script will create web-ready images for any new images it finds. One thing I do need to do to it is make it so it will update the photo if it has been modified.
dir=/home/photos/web-ready find /home/photos/large -iname '*.jpg' | while read file; do path=`dirname "$file"` name=`basename "$file"` if [ ! -d "$dir/$path" ]; then mkdir -p "$dir/$path" fi if [ ! -f "$dir/$path/$name" ]; then convert -auto-orient -resize 1100x1100 -quality 80 "$file" "$dir/$path/$name" echo Done $file else echo Skipping $file fi done
