Looking Forward to ApacheCon, CentOS Dojo Denver, and CloudStack Collaboration Conference in April

In just a bit more than a month, the mile-high city is going to play host to a triple-feature of open source IT goodness:

Starting April 7th and running through the 11th, you’ll have a chance to connect with folks developing and deploying some of the most used infrastructure in the world. Apache Web server? Check. Apache Hadoop? Check. Lucene, Solr, Libcloud, Kafka, Cordova…? Check, check… well you get the idea. Also CentOS and Apache CloudStack.

The schedule for each of these events is outstanding. Oh, and I managed to sneak in a few talks as well. I’ll be doing a talk at each:

You really, really don’t want to miss this year’s ApacheCon, and stay for the Dojo and CloudStack Collab because they’re also going to be chock full of goodness. You can register for ApacheCon here, and register for the CentOS Dojo for just $50 through March 20 and add the CCC registration there as well. Or just register for the CentOS Dojo on April 10th separately if you can only make one day.

Have questions about any of the events? Drop me a note by email or hit me up on Twitter, happy to try to help or find the right person.  Hope to see you in Denver!

Brief Review: Seiki 4K 39″ TV/Monitor

Just a bit ago, I blogged about getting a 4K monitor working on Fedora 20. Now that I’ve had a bit of time with the monitor, I wanted to comment on the experience a little.

Reviews on various sites really bagged on this monitor’s color/clarity compared to traditional computer monitors. While I don’t doubt discerning users might find flaws in this monitor, it’s just fine for my use case. That is, I spend the day using IRC, a few terminals, Web browser, PDF reader, mail client, and maybe LibreOffice.

If I’m using any sort of image editing/photo editing software, it’s strictly for cropping and re-sizing. So, honestly, it doesn’t matter to me if things are perfectly color-calibrated or if it’s good for gaming.

Compared to my 27″ Apple Cinema Display, I’d give it a B- or C+ for picture quality. But a small sacrifice of picture quality is well worth the extra desktop space.

Daily Use

The productivity increase I got from the 4K monitor was so great, I finish my work in half the time and have been promoted twice in the last week.

Uh, OK… not really. But we geeks are always chasing that tiny productivity boost, or searching to zap annoyances in our work day – and I’m happy to say there has indeed been a productivity boost and some zapped annoyances.

You can’t really quantify the improvement you get from a new setup like this, but if I had to… I’d say it’s 10%, maybe 15% more productive. I find myself spending less times tabbing through things, I can actually have four to six things open at the same time for a task without any need to tab through windows and find something. Example: Planning the Infrastructure.Next events, I can have a few emails or Web browsers open that have speakers’ abstracts, the Lanyrd page for Infrastructure.Next @ SCALE and Infrastructure.Next @ Ghent, a terminal for using middleman to update Red Hat’s Open Source Community blog, and still keep an eye on IRC/IM.


The 39″ monitor is the same distance as the 27″ monitor, which admittedly is not the best layout ergonomically. The top and far right/left of the monitor are just high/far enough away that it’s slightly uncomfortable. I’d like to push the monitor back about another six to eight inches, but there’s not room on my desk.


A few annoyances with the setup so far.

First, the power management and Fedora don’t seem to get along. I had to turn off power management in KDE, because either Fedora was crashing, or the monitor wasn’t waking up again or taking a signal after KDE put the display to sleep.

The monitor has a sleep feature that kicks in at a regular interval, and the option to turn it off is greyed out in its menu. So, every few hours I get a overlay display on the monitor telling me it’s going to sleep in 60 seconds. So I grab the remote, mash a button, and it stays awake. (Or if I’m not at the computer, I have to power it on again when I get back to the desk.)

Not a huge deal, but also a bit annoying.

It has a PC input for sound, but I haven’t found a way to select that input while also using HDMI, which is annoying.

The only workable input to get the 4K resolution is HDMI. I’d like to use DisplayPort, but that’s not an option for this display. I’ve read a bit about “active” DisplayPort-to-HDMI adapters that might let me use the laptop DisplayPort successfully, and I’m going to try that soon.


For my use, the positives outweigh the negatives, though I debate whether I should have waited for the Dell 4K monitors. Higher cost, but probably better quality and easier to set up.

But, you get what you pay for. The Seiki is cheap and available now. It works well enough that I’m sure I’ll get quite a bit of use out of it. Worst case scenario, I could always use it as a TV if 4K ever really becomes a thing for Blu Ray/streaming video and replace it with a Dell or another proper 4K monitor when they become more available.

If you spend all day at the computer, I’d strongly recommend checking it out.

A Quick Tip/Request on Social Media

Fail Whale One of the things I use social media for is to put the word out about projects that I work with/on and to draw attention to events or things that might be of interest.

Likewise, a lot of my friends are in a similar position. Whenever I peek into Twitter, Google+, or Facebook, I try to re-share/amplify things that my friends post that might be of interest to people who follow me or are connected to me on social media. This used to be sort of de rigueur for social media, but I’ve noticed that the practice has fallen way off.

Assuming your friends are posting things that might be of interest, you might consider boosting their signal a little and help to spread the word. I generally try to RT or promote other people’s events, posts/articles, and so forth at least as much as my own. And if I notice someone being kind to me on social media, I try to return the favor. (Note, this is not a request that everyone all become retweetbots or anything — just asking for folks to take a second and help promote other folks’ stuff as much as they pimp their own.)

The nice thing is that you have a chance to be exposed to things outside your own network, and I’ve run into a lot of interesting things, articles, and people that way.

Thoughts, comments, flames?

DevOps in DC Intro to Ansible

Going all the way to Washington D.C. for USENIX LISA next week? There’s lots to do at LISA (hint: Red Hat events, Fedora events) but if you want to get out and meet some of the local DevOps type folks who might not be at LISA, you might want to check out the DevOpsDC meetup on Tuesday night:

Introduction to Ansible with Michael DeHaan

Ansible is a radically simple IT orchestration engine that makes your applications and systems easier to deploy. Avoid writing scripts or custom code to deploy and update your applications— automate in a language that approaches plain English, using SSH, with no agents to install on remote systems.

Right now the group has 35 slots available, and I suspect as LISA gets closer they’re going to fill up quick. If you’re going to be in town, sign up and learn about Ansible. (And say “hi,” if you see me at the event – looking forward to meeting new DevOps folks!)
