I was having trouble with the mouse being too sensitive on my touchpad. After googling around I found this Dell page. I’ve followed the instructions (it was last updated Feb 2019), with the following changes and modifications:
16.04in all kernal and file names (e.g. in Step 3);
*in Step 5 iii in the file name
sudo gedit /usr/share/x11/xorg.conf. Read the rest of this entry »
Just bought a Dell XPS 13 Developer Edition with OEM Ubuntu (18.04 LTS Bionic Beaver) installed.
As I was setting the computer up for the first use, it asked me if I wanted to create a recovery key (i.e. disk or USB), but indicated that you could also do this later. I didn’t have a USB key with me, so I skipped the step.
Once I got set up, however, I wasn’t able to see where I could access the utility to make the recovery disk. I thought the dialogue during set up had said the Ubuntu app store, and various Dell sites seemed to indicate either the app store or launchpad. Read the rest of this entry »
I had been working experimentally on a file a couple of days ago and forgot to change the name to something meaningful. I remembered roughly when I was working on it and would recognise the name and context when I saw it (probably). But the problem is how to you find the relevant files? Stackoverflow to the rescue (as always), with a bit of
find /home/dan/ -name *.xml -mtime -2 -ls |more
It’s all pretty self explanatory except the
-mtime -2: the utility, the start directory, any restrictions on the file name (you want to use this if you are searching a home directory: I have 10k+ files, it looked like before I added it, given all the cache files from the web browsers), the time period in days (-mtime), and a ls-style display. |more is a pipe that allows you to look at the output in segments if there is more than a screen’s worth.
-mtimeis the only funny bit: it searches back the number of days expressed by its value. If the value is positive, it searches bac Read the rest of this entry »
A problem I’ve had lately has been how to find and replace text in multiple files from the command line. Since I keep googling the answer, here’s a post to remind me. It is based on this page: https://superuser.com/questions/428493/how-can-i-do-a-recursive-find-and-replace-from-the-command-line
find . -type f -name "*.txt" -print0 | xargs -0 sed -i'' -e 's/foo/bar/g'
Note that unlike the source, I have
-i'' rather than
-i ''. This seems to required on a *nixes.
I also discovered (mostly ‘cause I’m not good at regular expressions, I suspect), that if you are searching and adding things in < and > that you need to escape everything except the first and the last < and >. Read the rest of this entry »
I have a strange problem in the gnew gnome windows manager that ships with Ubuntu 17.10: on my three-monitor desktop, application windows occasionally open off screen. I.e. in the following screen shot, they open partially or entirely in the space marked “invisible window” to the left or right of the tall window.
To make matters worse, applications that open like this do it all the time. I.e. Read the rest of this entry »
An interesting issue with the *nix ls command, or, why you should never begin a filename with a hyphenPosted: December 6, 2017
In which I discover an odd error using
ls and learn how to solve it.
There are many articles about this on the web. This is just a reminder to me as to what I’ve been doing.
Change boot to developer mode
Doing the following deletes all local data on your system. You can always reinstall the Operating System (Chrome seems to do that remotely). But your data is wiped after you do this.
- Hold down the ESC + ↻ (refresh) key (the refresh key is where F3 would be on a normal keyboard)
- While holding them down push the ⏽ (power) key (top right corner). Read the rest of this entry »
I need to use Vidyo conferencing software for some projects I’m on. Because I just reinstalled Ubuntu 16.04, I needed to reinstall the Vidyo desktop.
This is not easy, since the installation file Vidyo directs you to contains a dependency that is not available on Ubuntu 16.10 (libqt4-gui).
There are various solutions out there, though I was not able to get the one proposed by Vidyo itself to work.
Just updated my CMS (Textpattern) to the latest version (6.4.2). I had to because the University just updated the PHP on the server and this broke the old install.
This document is a quick primer on using TextPattern, the Content Management System that controls my web pages. It covers the basics only.
After I have made you an account, you should receive login information in an email. Read the rest of this entry »
This exercise is an experiment in “phonetic” spelling, that is to say the use of orthography to capture sound.
In doing this, we are trying to get a sense for how people in previous eras might have used one spelling system to transcribe another language—e.g. use French spelling to write Middle English, or adapt Latin letters to spell Germanic languages.
This is not an exercise in the use of modern Phonetic Alphabets (e.g. IPA). If you know phonetic transcription, try to ignore that knowledge here. Read the rest of this entry »
For a little while, I’ve been surprised by popups on my blog site dpod.kakelbont.ca (tl;dr: they don’t happen any more because I removed the SweetCaptcha plugin).
I’m not quite sure the contexts in which I’d been seeing them, but for whatever reason I thought they were coming as an artefact of something else: a bottom banner on my cellphone that I was accidentally touching or something similar.
But today it became clear that there really was Something Amiss. When I checked on both Chrome and Firefox, it was happening the first time I clicked on any page link in my site. It took a little while googling for a solution (turns out a lot of people want popups to appear in their Wordpress sites and most things I found were about how to make them happen).Read the rest of this entry »
How you do this depends on whether you are setting it up for the first time or want to restore already-saved files from Dropbox to their correct place.
First time (i.e. you have never used dropbox to backup your files)
- Install dropbox
- In the terminal, navigate to the Dropbox folder (probably
- Soft link to each directory you want to backup in dropbox (i.e.
ln -s ~/Documents .,
ln -s ~/Desktop . Read the rest of this entry »
