Exploring my way out of Imposter Syndrome

  • Running Presenter Decks

    Last week, i was involved with Reaktor Breakpoint, a tech, design, business and future conference with about 600 attendees and twenty-odd speakers.

    Unlike with last Breakpoint in 2015, i wasn’t involved in the planning bits, i just worked with the execution. On the surface, my job sounds trivial. I was to make sure all presenters’ slides were delivered to the right stages, in time, before each presenter’s show, and looking awesome.

    I like to emphasize the last word of the previous paragraph, because that is your job and the job of nearly everyone working backstage or in production: making the presenter look, sound, and feel awesome.

    While delivering slides may sound like the job of a glorified runner, it was actually quite a bit of logistics than i’d originally expected.

  • Dabbling With Docker

    For me, Docker’s been this black box that people say is the best thing ever and is so easy to get into and just package everything with Docker and things’ll just work. Yeah. Right. I don’t trust that at all.

    So i’ve decided to learn something new. I’ve decided to demystify Docker.

  • Manfluenza

    I’ve been sick in a way that can only truly be appreciated by experiencing it. I’ve had manfluenza, which is the male version of any disease and is by definition worse just by the virtue of you being male. We’re not as good at handling pain. And yes, i’m joking. A bit.

    I was about to write a long technical post about my illness, but i’ll just lay down the short and sweet.

  • Cable Feng Shui

    Your network will always grow, and due to the laws of entropy, left to itself, it’ll grow messier. Here are some things to consider while it’s still small and manageable:

  • Link Aggregates and Virtual LANs

    A Link Aggregate (or Network Aggregate) is what you get when you push a single network link over several cables at once. In HP switches parlance, this is known as a trunk and in the Cisco dialect as an EtherChannel Bundle. On HP servers, it’s NIC Teaming and in other places it’s called Link/NIC bundling or bonding. In this post i’ll just call them Aggregates, and Aggregates are your friend.

  • HP Switch Certificate

    Setting up a SSL certificate on a HP (HPE/Aruba) 2530 switch is not hard or complicated but it is frustrating when you try to figure out exactly how it’s done. There’s some terminology that isn’t immediately obvious and the switch tends to be a bit picky about how things are done. So with that said, let’s dive in. I’ll assume here that you have a functioning PKI on your site, or that you’re able to get a certificate request signed somehow.

  • Some Nice HP Switch Settings

    I’m kind of fond of the HP (HPE/Aruba) 2530 series switches. They are mostly no-nonsense and fairly nice to configure from the command line.

  • Sharing your `known_hosts` among your admin peers

    The first time you contact an ssh server, you’re presented with a fingerprint and asked whether you want to trust the server to be who it is, based on this fingerprint. Blindly, i might add. If you’re at least a bit concerned about (usable) security, this should send a few shivers down your spine; how the heck are you supposed to know whether this fingerprint is right or not. If you’re managing your servers with ansible, this query can be inconvenient, as it stops your flow at some random place and it’s not entirely clear where it will commence.

  • Hugo, Custon Domain, Letsencrypt Certificate and Gitlab Pages

    Setting up https on a hugo site on Gitlab pages with your custom domain requires some manual work, but if i can do it, so can you.

  • The more Separator

    TL;DR: To preserve html styling in summaries on hugo, use the tag <!--amore--> (removing the letter a) in your text.
