Instead, There Will Be No Kolab 18

We had previously planned for a Kolab 18 release, but given the additional work associated with slapping a new version number on an otherwise fully compatible series of enhancements, have decided against it.

Kolab Now Really Beta (DevOps Edition)

This week, I accidentally made Kolab Now Beta really beta — though pre-alpha more than beta, strictly speaking — completely intentionally; Oops, I #devops'ed https://t.co/zp9ncO0w1k — Kolab Operations (@kolabops) September 5, 2017 I can now proudly announce it runs off of otherwise public GIT source repositories directly, and the developers working on the projects involved…

Performance Testing w/ Fedora Help(*2)

In the next couple of weeks or so, we’ll be executing performance testing of Kolab on OpenPower in one of the world’s largest testing facilities. How do we do this? With help of Fedora(^2). Part I: The Data Set A good performance test requires a good data set. In the particular set of tests, we…

Kolab for Open Power

Among a variety of deliberations concerning the security and transparency of a little Kolab thing running anywhere — at home, rented space or hybrid cloud — this post is about the transparency of the hardware layer, and our ongoing efforts to make that so. We have said what, why and how on LWN, at events…

The 3rd Pillar to Save Your Ass

A controversial topic, to say the least, is what happens when you double-click a message in a Roundcube messages listing, while also having enabled the preview pane.

Purposefully Not the Center of Attention

I disagree. One can arguably not…

Kolab 16.1 for Jessie: Way Ahead of Schedule

I reported before that I was a little ahead of schedule in making Kolab 16.1 available for Debian Jessie, and as it turns out I was wrong — I’m way ahead. In fact, installing and configuring Kolab 16.1 on Jessie passes without any major head-aches. I think the one little tidbit I have left relates…

Service Window: git.kolab.org migration

It’s been a while since we last updated Phabricator, and it’s been a while since the overall system that runs git.kolab.org was paid attention to. Suffice it to say that it’s time to upgrade the system. We’ve meanwhile packaged Phabricator and its dependencies, stripped off some superfluous external dependencies that it shipped, and fixed some…

Apple on Guam: The Dots on The i

I’ve said before we had gotten reports from people that voluntarily participate in the Kolab Now Beta Programme, that the iPhone iOS and Mac OS X Mail.app were not really happy using IMAP over implicit SSL (you know, the one on port 993). Here’s a summary of the things that have happened thus far; Supply…
