merging centos iso images

Thanks to @Anon on Unix.SE for the pointer on how to do this. And to @Andy‘s comment on @mmckinst‘s answer for the warning about additional packages you may need. As my three readers know, I run a CentOS mirror. One of the idiosyncrasies of CentOS, like its upstream RHEL, is that DVD ISOs aren’t always just one image – […]

columnar “email”

There needs to be a better way of handling group conversations. IRC uses the constant scroll mentality. Email has reply-at-top, reply-at-bottom, and reply-inline. Forums, reddit, Google+, Facebook, Twitter, and the like have a scroll-like view – every new post is merely sequentially listed after the last. This can all lead to highly confusing digital conversations. […]

what should an “ideal” support ticketing system provide?

If you were going to create a support ticketing system from scratch – what would you put in it? My initial list of needs (some of which derive from my book, Debugging and Supporting Software Systems, and other from my experiences in ticket smashes): “long” title support (HP truncates at 80 characters – give me at […]

apps on the network

{This started as a Disqus reply to Eric’s post. Then I realized blog comments shouldn’t be longer than the original post } The app-on-network concept is fascinating: and one I think I’ve thought about previously, too. Hypothetically, all “social networks” should have the same connections: yet there’s dozens upon dozens (I use at least 4 […]

soup to nuts mirroring of centos

I run a CentOS mirror. Have for a couple years. But I never stopped to see just how long it takes to start becoming a mirror. In case you wanted to know, I created a quick DO VM and ran the rsync mirror job yesterday. The results? At ~2.5MB/s, it took just over 8 hours to download […]

a public – or white-labelable – rfe service a la uservoice, but easier to use

I’ve seen some services that utilize uservoice to handle requests for features, functionality, etc. And I have seen companies have formal Request For Enhancement / Enhancement Request / etc processes (generally culminating from support cases (hopefully from good ones)). What I don’t see, though, is a way to either limit who can submit requests (uservoice, for example, […]

To add to my tutorial collection, here’s how to setup EtherPad on CentOS 6 (x64). As in the IRC tutorial, I used a Digital Ocean VM for this What is EtherPad? It’s an open-source collaborative text editor that works like Google Docs – ie, all editors/viewers can see changes from everyone else in realtime. Here’s […]
