“Slack is killing email” – yeah, right

Responding to glorified technology advertising publication The Verge running this silly clickbait headline a while back, here’s my prediction on where Slack will eventually end up. As posted on Twitter, recorded here for posterity.

Google Calendar support in Thunderbird (and importing iCal files)

Capping off a nightmare week for standards support and the open web thanks to Google, they have also announced they are dropping support for the CalDAV standard later this year. I’ll have more to write on this topic in the near future (and the general gullability of social networks fanboys who are clueless about why open standards support actually matters), but for now the takeaway for Thunderbird users is that the CalDAV method of connecting to Google Calendar using Thunderbird and Lightning will soon no longer work.

Fortunately and thanks to the outstanding efforts of Philipp Kewisch, Lightning will continue to work with Google Calendar using Google’s non-standard Google Calendar API.

To get this to work, your Thunderbird client will first need the Lightning add-on to be installed and enabled. Next, download and install the Provider for Google Calendar add-on, and restart Thunderbird. Now, when adding a new network calendar you should see an option for Google Calendar:

Create a new network calendar

The address to put in the “Location” field in the above screengrab can be found by using the Google Calendar web interface, at “Settings -> Calendar -> [your calendar name] -> Calendar Address”. Clicking on the “XML” button will display the calendar address to use:

Google Calendar network address

Upon applying the remaining settings your Google Calendar should be up and running in Thunderbird. Due to Google’s assholish disregard for open standards of late, I’d strongly recommend donating to the continued development of the add-on (I have).


A problem I encountered when doing this, and not related to Thunderbird or Lightning, was in trying to import an ICS-format backup of one Google Calendar into another. In short, the following thread describes the problem and the resolution which worked for me:


The curious case of Postbox

Whilst working through some Gmail/IMAP/Thunderbird issues a while back, a reader left a comment with a recommendation to check out Postbox, an email client which amongst other things bills itself as “an awesome alternative to Thunderbird”.

As far as I can tell, Postbox is actually a Thunderbird fork, wrapped up in a non-free license with attendant commercial licensing terms and a fraction of the platform support. You get Mac and Windows, and some vague mutterings about demand potentially influencing a future Linux version. UI prettiness aside, a fair number of the advertised goodies seem to have their origins in recent Thunderbird releases, such as improved Gmail support and cloud storage service provider integration. So that’s some of the uniqueness of Postbox already gone.

Regarding the licensing, one of their blog entries entices users to switch to Postbox, highlighting Google’s purchase and subsequent shutdown of the much loved Sparrow email client. Considering Google could just as well purchase Postbox any day of the week they choose, Postbox users depending on proprietary functionality offered by the application would be just as much up shit creek, with no community support in the case of an acquisition and closure.

Licensing and duplication of features compared to Thunderbird notwithstanding, you’d probably expect to get some premium support for the cash shelled out for Postbox, right? Actually, you don’t get any support. That’s right, none. If you look at the Postbox support FAQ, they’ll tell you to read the manual, read Mozilla’s support forums (what?), Google the issue (what the hell??), and at the end of all that:

“Please note that we do not offer one-on-one support offerings to new users at this time. All support efforts are currently dedicated towards providing better documentation and self-help solutions so that our users can more quickly find the answers they need.”

You’d think personalised support would be close to the top of the list of desirable features for any commercial deployment, but apparently the folks at Postbox see it differently…

To recap: proprietary license and associated risks, not free, limited to two operating systems, most features already present in Thunderbird, and no actual support. What are the advantages of this application again? And is Postbox just hanging around in the hope of cashing in with an acquisition itself?

Personas for Thunderbird

Just a quick post because clearly I am the last person to know about this – but Thunderbird supports Personas. So, just like Firefox, you can beautify your favourite desktop email client with thousands of lightweight skins:

Now, we just need Sync for Thunderbird
