I’ve just written a quick and dirty guide on how to use Certbot on Debian 9 with Route 53. This is useful if you are trying to manage wildcard certificates and don’t want to, or can’t, screw around with managing the current state of the Route 53 plugin on Debian 9.

If you’re loooking for a bit of light reading before bed, this might be just the answer: An Advanced Introduction to GnuPG.
On a mostly related note, I’m going to move all of my (admittedly trivial) secure e-mail to my ProtonMail account. If you have any reason to contact me securely, I advise you e-mail with GPG at gmobrien at protonmail dot com as of December 2018.
No big editorial, just a note for folks who have reason to use any of my GitHub projects and read the blog…
From here on, I’ll be maintaining any public software over here: https://gitlab.com/gmobrien
After a few shenanigans with Rogers and Teksavvy, I managed to switch over to my cable Internet service yesterday. Thankfully the only issues were administrative. After 24 hours of service, I’m cautiously optimistic that my local segment doesn’t seem to be especially congested.
I’ve not quite cracked 100Mbps download speed in any of my tests, but I have been able to hit 98Mbps pretty consistently and I’m always hovering around 10Mbps up. My ping times seem to stay to between 10-15ms to servers hosted in the downtown Toronto core. This is up about 5-7ms from my DSL service, but I’m fortunate enough to have always had good ping times in artificial tests simply because of location and this doesn’t seem to be a showstopper. I guess I’ll know more when I get a chance to sit down and play a few online games.
Last night during the supposed peak usage period, I was only seeing a drop in download bandwidth of 3-4Mbps at worst and barely any difference in upload bandwidth at all. My latency did increase a little bit as well but never more than 5ms and most of the time it was closer to 1ms.
If this holds, then four times the bandwidth is a fair trade for not having the lowest ping on the server! I thought I’d share this in case anybody else is considering Teksavvy cable as I found it incredibly hard to find anything other than horror stories which were clearly a result of unique circumstances when I was researching the switch.
Here’s a link to my Speedtest results if you are interested in a bit more detail.
So for the first time at home I have what until relatively recently would have been viewed as LAN speed for my Internet service, and with an unlimited, and reasonably managed bandwidth policy. I’m not an abusively high user, I’ve almost always stuck inside my current cap on my DSL service, but I do appreciate that a good service provider should manage their networks during extreme congestion.
My experience with Teksavvy has been positive enough over the years, I’ve been a customer since 2006, and I’ve only ever had one provider that was better and this was back in the .com bubble days when Ottawa was crawling with technically savvy and responsive providers! So I’m giving them the benefit of the doubt that they will not do anything naughty with their traffic shaping policies. Continue reading
I am in the process of getting my new photography site going, I’m hoping this spring and summer in particular are going to be very productive. I’ve been playing around with some new techniques and hope to have some new photos up soon.
For now, I’ve been curating my old photos and getting things organized.
I’ve been using WordPress for this site for about 6 years and am generally quite happy with the fact that it “just works”. I’ve been using a simple default theme (Twenty Twelve) for much of that time as well. Recently I’ve been trying to be a bit more active on the blog and there are few (very minor) issues and personal taste differences I have with the theme which I’ve hacked out it of it.
I was doing some reading on how best to integrate SmugMug with the site since I’m on the verge of switching from Flickr for my personal photos and while I was doing this reading I discovered that there is a correct way of modifying themes for WP! It’s actually quite elegant and avoids several potential problems.
I give you WordPress Child Themes.
So this is a bit of a take 2 (3?)… I recently recovered the database for the old community forum that used to be hosted on quay.net. I had thought that it was completely lost due to a bad backup and crappy hard drive, but it turned out that I had a copy of the backups stored on my old laptop!
I don’t know if it’s something worthy of full resurrection yet, but at the very least I thought I’d migrate the data to BB software that was supportable and put the old content back up in case people would like to get at their old posts.
For the time being at least it can be found over here.
I’ll likely share this with people via some social media as well once I figure out what to do with the data. If you’re returning, I’d encourage you to take a look at this post.
Since I’ve breathed a bit life back into this blog, I was playing around with using Google Fonts, deciding to use the Ubuntu font as an example. It turns out that this was a singularly unfortunate choice for testing!
There is a known issue (without an apparent resolution) which under certain circumstances can cause problems with rendering the apostrophe character. In my case I was seeing small superscript 9 characters instead of apostrophes.
There is an example of the issue appearing in a different context on the Xojo forums.
The easiest solution in my case was simply to use a different font. I wasn’t a big fan of how Ubuntu renders minuscule w anyway.
Now that I’ve converted the site to use TLS, I’m going about replacing my old homebrewed Flickr plugin to use SlickrFlickr since it seems to be maintained and has similar, but extended, functionality.
I switched mostly so that I wouldn’t have maintain my own plugin, unfortunately I discovered after I finished setting up SlickrFlickr that it only returns the http scheme and not https scheme for the Flickr API.
Not to be too discouraged, I’ve created a simple fix for this and even though it’s a freemium plugin, I may submit a patch to the developer because it’s so simple.
There are three variables that contain the URL scheme in them:
# the variable $url in phpFlickr.php sets some image locations
sed 's/\$url = \"http/$url = \"https/g' wp-content/plugins/slickr-flickr/phpFlickr.php
# these strings also need to be changed in slickr-flickr-api-photo.php
sed -e 's/\$this->url = \"http/\$this->url = \"https/g' -e 's/\$this->link = \"http/\$this->link = \"https/g' wp-content/plugins/slickr-flickr/slickr-flickr-api-photo.php
I’ve actually implemented it as a check in my own local copy of the plugin by verifying the Apache server variables to figure out if the connection is HTTPS. I just don’t currently have this implementation in patch format. I will post it soon.
