Fixing “couldn’t parse private ssl key” in Dovecot

I run Debian Linux including a mail server, and part of the system is Dovecot, an open source IMAP and POP3 server which has always worked well for me.

Unfortunately it stopped working after an upgrade. With Linux I am in the habit of doing:

apt-get update

apt-get upgrade

to keep the system patched, and

Server shipments decline as customers float towards cloud

Gartner reports that worldwide server shipments have declined by 4.2% in the first quarter of 2017.

Not a surprise considering the growth in cloud adoption but there are several points of interest.

One is that although Hewlett Packard Enterprise (HPE) is still ahead in revenue (over $3 billion revenue and 24% market share), Dell

PowerShell documentation stubs: frustrating for users

I’ve been writing a piece on PowerShell, Microsoft’s generally excellent scripting and automation platform. PowerShell is also largely open source, in its cross-platform, PowerShell Core guise.

Of course I went straight to the official documentation as part of my research. Looks good; but I was puzzled. I would find a promising topic like Object Pipeline,

Windows S: another go at locking down Windows, but the Store is not ready and making it ready is a challenge

There were two big ideas behind Surface RT and Windows RT, the 2012 Windows 8 project which left Microsoft (and some OEM partners) with a mountain of unsold hardware. One was to compete with iPads and Android tablets by making Windows a touch-friendly operating system. The second was that Windows had to move on from

Xamarin Challenge shows bumps in Microsoft’s path to cross-platform mobile

Microsoft ran a Xamarin Challenge over on Paul Thurrott’s site. The idea was to demo how to build a cross-platform mobile app with Microsoft’s cross-platform mobile toolkit.

The challenge was in three steps. You build a weather app, complete with crash analytics on the Visual Studio Mobile Center.

Microsoft financials: cloud good, Surface down, and “We had no material phone revenue this quarter”

Microsoft has released its financial results for the third quarter of its financial year. Revenue was up 8% year on year, and operating income up 6%. I’m always interested in the segmentation of the figures so here is a quick table:

Microsoft needs to fix its Android emulator

Microsoft wants Windows 10 to be an ideal developer operating system, with its Linux subsystem, and Visual Studio 2017 is notable for its strong cross-platform development tools.

There is an annoyance though. Google’s Android SDK includes an emulator for debugging mobile applications, but it requires hardware acceleration in the form of Intel’s HAXM (Hardware

Disabling automatic update restarts in Windows Server 2016

Windows Server 2016 is in effect the Windows 10 version of the server OS. If you look in Settings it seems to have the same attitude to updates; in other words, you get them automatically whether you like it or not. Currently my server is even offering me Windows 10 Creators Update:

However, I
