Updating mailman on Centos 5 due to DMARC

Recently, some major service providers (notably Yahoo, Comcast and AOL) decided to bounce email that did not conform to the DMARC standard. As a side effect, this broke many long-standing configurations for mailing lists. Full details on this can be read elsewhere: http://www.spamresource.com/2014/04/up-in-arms-about-yahoos-dmarc-policy.html http://wiki.list.org/display/DEV/DMARC If you’re like me, you have a CentOS 5 machine running […]

Unbuckling the safety belts

In the last year or three, many programming languages, libraries, browsers and applications have been getting stricter and stricter about how they handle and accept SSL certificates. Of course, this is due to more and more exploits showing up in the wild. So now, formerly acceptable actions are getting warnings, and former warnings are causing […]

A killer business idea

I think I’ve had the best business idea I’ve had in years. It’s simple. I want to make a DNS registrar. Yeah, I know there are dozens of them. But this is the difference: It will be a ZERO UPSELL registrar. I will charge you what is the basic price I can to make the […]

“DevOps” washing…

I work for the professional services division of a company that is mostly a storage reseller. (VAR) What this means is there is often a desire to package up services that people like me can provide along with the hardware that we sell. The professional services side is often a nice add on. Think of […]

Today’s mischief – ROMAN DEATH!

Today’s mischief is brought to you by the line-noise that you can compile: Perl! You can add this code ANYWHERE in an executing perl stack. (a module, a referenced library, an inherited base class, etc) Then at any point the perl application warns() or dies() and shows the accompanying error, the line number is shown […]

DevOps Days – Silicon Valley 2013

I let the whole journaling thing go for a while, so I think I should fill a few key things back in. Most of my work of late has centered around the DevOps movement and related technologies. In many ways, it’s providing terms and frameworks for stuff that I have long know was “the right […]

Getting a newer version of git onto CentOs 5

Ah the joys of working with vintage OSes. So if you add the usual yum repositories to CentOs 5, git and curl are available in the updates repository. However, if you try to use git and do a push to a web DAV-based repository, say somewhere like github.com, you get the following error: $> git […]

An interesting error on “cvsimport” for git.

I’m writing this up in the hope that google might pick it up, and that it might help people in a similar situation. Lately I have been moving from CVS to git for the storage of my source code. When converting all my projects over, I used tge “cvsimport” function of git. Though a few […]

SSD, Macbook Air, and CPU

Some of you folks know me as an Apple user. I dont evangelize, as that never does any good, but I have been using apple computers off and on since about 1990-ish. On my last major job-switch (which has been an amazing 6-month roller-coaster of a ride, that I hope to be able to post […]

VMware Guest OS Ids

A lot of the VMware APIs required guest id’s to label the OSes. And yet, I can’t find a white paper anywhere that lists the full list of them. This capture was buried on a community thread, so I am including it here for my own future usage. If it helps you out too, then […]
