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.
Here’s a problem I wasn’t able to find a solution online to…
Sometimes, when you import a document into Google Doc from a different wordprocessor, you can end up with the problem that the table is wider than the page. The following is an example:
The problem is that there is nothing to grab on the top ribbon to pull the edge of the table back. If the problem was the internal alignment of the columns, then you could use a slider in the ribbon bar:
But since there isn’t one, then there’s nothing to grab.
The solution is to go to Table>Table Properties and then uncheck the column width button. Read the rest of this entry »
Some quick reminders for my own use about master slides in Office
Turn on default sections
Impress master slides come with some sections built in (e.g. slide count, date, etc.). But by default these sections don’t appear unless you turn them on.
To turn them on:
- Insert > Header/Footer > make sure the relevant section is checked in the dialogue that opens.
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 quite like using Google Docs. I’m less crazy about Google Drive.
One of the common issues I have with the relationship between the two comes when I am given the direct link to a Google Doc or Sheet as part of a project. I often want to access (or start) other documents in that same folder. But until now I never knew how to find that folder (everything I learned comes from this page).
It turns out that all you need to do is click on the little folder icon beside the file name (highlighted in yellow in the following image):
When you do this, a dialogue opens up with a “Move” button. 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.
I’ve spent a frustrating couple of days trying to squeeze things into a Google Docs table that was too narrow for its content.
The problem was that while I could move individual columns within a table, I simply couldn’t find the way of widening the outer boundaries of the table—i.e. moving the leftmost border to the left or the rightmost border to the right. Making things worse, I had been able to do it a couple of weeks ago. But nothing I was doing seemed to work now.
The trick turned out to be remarkably easy, though it points to a UI problem in Google Docs. Basically, Google Docs allows you to adjust column width in two different ways: by reaching up into the measurement ribbon at the top of the document and moving columns there (when you do this, you see a left-right arrow cursor [⇔] that has not been captured in the screenshot):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 »
Paperpile allows users to put in their library’s ezproxy server. This allows the system to search for PDFs licensed through the university library, especially when off campus.
Although Paperpile has proxy addresses for a lot of Canadian universities, it doesn’t have one for Lethbridge. After doing some digging, I think I was able to find out ours:
I found information on the server here (specifically about how to log in to JSTOR using it). Read the rest of this entry »
