Today I revisited a post by Martin Fowler on Sacrificial Architecture from last year because I was looking for this quote:
“design for ~10X growth, but plan to rewrite before ~100X”
Thanks Lars Fosdal for pointing me to it in the first place back then.

Back in the Visual Studio 2010 days there was a request for Printing source code with syntax coloring.
Then, the Visual Studio team released an extension that did just that: Color Printing Extension Now Available! – The Visual Studio Blog – Site Home – MSDN Blogs.
It got updated for Visual Studio 2012 in the gallery Color Printing extension, but that does not mention it has moved to the Productivity Power Tools 2013 extension.
Both tools are from the Visual Studio IDE team, and mentioned on their blog.

After a recent big update to OpenSuSE Tumbleweed, I could not ssh into my system any more.
The ssh client side would report a Read from socket failed: Connection reset by peer which I misinterpreted as the sshd not running at all.
Luckily the server is a VM, so I could reach the console. There I saw this:
sshd trying to load files it shouldn’t
The files should not be loaded as they are not specified in the sshd_config file:
dsa and ecdsa not specified in the config file
So I knew something was broken. After reading some messages in the forums.opensuse.org I got at Bug 977812 – sshd killed by SIGSYS on client connection
As usual with such issues the cause seems a combination of factors:
And we have the culprit, I believe: together with the glibc upgrade, openssl
was updated from 1.0.2g-1.1 to 1.0.2-2.12 which brought, among others, patch
openssl-urandom-reseeding.patch.
A temporary fix is to comment out a line in /etc/sshd_config so you get this diff:
-UsePrivilegeSeparation sandbox # Default for new installations.
+# UsePrivilegeSeparation sandbox # Default for new installations.
Be sure to undo this as soon as you’ve received a final fix.
A final fix is being fast-tracked so it appears in Tumbleweed soon.
I will report after deployment of [opensuse-factory] New Tumbleweed snapshot 20160502 released! as I think it contains the fix.
I already knew about openQA: Test summary which lists the builds, but not the changes in the builds.
Reading through Information Board or the like for Tumbleweed I found the openSUSE Mailinglist Archive: opensuse-factory which does the announcements and release notes for Tumbleweed.
It had both the announcement of the “big patch”, ssh bug report and temporary fix:

On Mac OS X, to solve the Python error “ValueError: unknown locale: UTF-8“:
Add some lines to your ~/.bash_profile then re-start bash (or re-login):
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

If you have a Raspberry Pi left, then you can make this:
The PiDP-8/I is a modern replica of the 1968 PDP-8/I computer. It’s open-source hardware, so schematics, design files & software are available.
