Blast from the past: 超獣機神ダンクーガ (Super Beast Machine God Dancougar)

After quite a long time, I was finally able to take a look at this series: a rather atypical mecha show that despite some bad production, still manages to be interesting.

Partings

Because changes occur when one least expects them. This post is about one such change.

DIY KVM over IP with pikvm

(Note: this post also appears in Planet KDE and Planet openSUSE because I thought this might be interesting to others)

As I mentioned in some other posts, I have a small “server” which I use as a NAS to provide archiving for photos and other files of interest. As it runs in a remarkably small (and quiet) enclosure, I’ve managed to put it in an incospicuous part of the room it is in. For the most part, it runs without a hitch: but in some (rare) occasions it needs to be looked at, and sometimes either logging via SSH is not possible, or it is not enough to diagnose the problem. In other words, I need to check what’s on the display. And the position it is in means that attaching a monitor and a keyboard can be inconvenient at best. In other words, I needed out-of-band management.

Quick tips: Server Name Indication for internal domains with Turris Omnia

Omnia?
#

The Turris Omnia is quite a nice (although a little pricey) OpenWRT-based router from CZ.NIC. It provides a fairly powerful CPU, relatively unconstrained eMMC space, and quite a lot of hackability (some revisions even have GPIO ports to play with). It runs a modified version of OpenWRT, named TurrisOS.

The problem
#

A few years ago, I built a custom NAS for my storage needs, using a cheap Intel SoC (J1900 chipset) and a (much pricier) mini-ITX small form factor server tower. While I want it to be primarily a NAS, I wanted to run a few services on it, for example Nextcloud or Pymedusa. Of course, in these days it’s better to use HTTPS, and the process is both cheap and fast using Let’s Encrypt. I also wanted to use SNI with multiple subdomains (files.example.com, medusa.example.com, etc.) pointing to the same internal LAN IP (because some of the software I used is much harder to set up with subpaths of a single domain).

Fixed comments

Sat, 09 Jan 2021 02:14:57 +0100

The migration happened and well… it turns out that it was not as smooth as I expected. In particular, comments weren’t working at all due to a filesystem permission on the database (which meant nothing would get written at all). That is now fixed. Sorry for the problems.

To add problems over problems, I had a hardware failure (RAID card) last June, which wrecked the root filesystem and I had to reinstall everything from scratch. When I looked back to recover the last comment backup… Well… it wasn’t being backed up. I was able to recover the ones up to 2015-2016 or so because I had still my old Disqus export laying around.

Refreshed look

Wed, 06 Jan 2021 00:30:09 +0100

You might have noticed that the blog has a markedly different look than before. It has not only changed visually, but also under the hood. This (brief) post summarizes the reasons behind the change.

Why?

Simply put, the previous solution was unmaintainable. “But,” you might say, “it was a static site generator! How could it become unmaintainable?”.

I'm back

Wed, 27 Aug 2008 19:00:42 +0000

Sadly (for me) I’m back from the holidays. For those of you who wondered why the updates on Japan stopped: when I got back to Tokyo I didn’t have an Internet connection, so I had no means to update. The whole holiday was a blast, though, and we’re considering getting back in two years.

Aside from that, work has picked up a really fast pace immediately (why on Earth journals don’t accept LaTeX-produced PDFs?) and I expect a round of meetings and planning to start soon to plan the next three months. I had a poster accepted at the ECCB 2008 conference, but the steep fees (1200 euro for flight, registration and lodging) made me reconsider. Better luck next time, I guess.
