Are You a Puppet?

So I’ve never cared much for the whole DevOps thing and I sort of snicker when it’s mentioned at the office but hey, I get that it’s one of the cool new buzzwords. I get that it makes managing a ton of servers considerably easier even if it means (as a developer) that I have to remember to disable the agent when I’m playing around or my changes will be overwritten. I decided that even though it’s not really part of my playground, my servers are all controlled by the Puppet master and it might be good to have a working knowledge of what it’s doing.

My Macbook is Screaming!

I’ve been teetering at the edge of my Macbook Pro’s hard drive limit for a while and completely ran the 500GB drive down to 0 bytes free once. I’ve been wanting to upgrade to SSD for a long time but I didn’t want to just swap it out for a similarly sized drive. Unfortunately, the prices of larger drives continued to be more than what I wanted to pay. Finally, after a long wait, my vision was to be realized.

Updating SSH Key List

While playing around with x2go tonight I realized I’d missed a critical step so I thought I’d share it here in case you run into the same problem. When I added my default (id_rsa) public key to the session configuration and enabled auto-login I was prompted several times to enter the passphrase. Unfortunately, the default key doesn’t have one. Rather than creating a new one that I’d have to update wherever it’d be used I opted to create a new key that included a passphrase. No problem, right? Right.

Sharing SSH Keys

Oooh boy work has been insane. I can’t believe it’s been so long since I updated anything. Not that I haven’t been studying, of course. Unfortunately, though, I’ve been so tied up I didn’t meet my goal of getting certified by the end of 2015. So I’ve adjusted that to 2016. 🙂

I’ve been playing around with stuff like GitLab and Github and so tonight I setup my own GitLab server. I decided I wanted to be  a good Linux citizen and use SSH keys instead of passwords when I hit a stumbling block I’d forgotten. My Mac doesn’t include ssh-copy-id. Thanks Steve.

I Have an IDEA

As a software developer by trade I’ve been coding in Java for about a dozen years. I’ve tried a number of integrated development environments (IDE) during this time and one stands out as head and shoulders above the rest. I’ve never been a fan of two of the more popular IDEs, Netbeans and Eclipse. Read More

99 Percenter

Well, I’m almost done with my Linux+ studies. I’ve reached the 99% mark and it feels good. I’m still in the review process and I’m trying to bone up on some areas but overall I’m feeling pretty good.

la-progressI hope to have some positive results to report soon!

modprobe

Objective: System Architecture
Here’s a little tip concerning modprobe. As you review the man page for this tool you may see the -l option. Pay attention to the verbiage: List all modules matching the given wildcard (or “*” if no wildcard is given). This option is provided for backwards compatibility. Read More
