First there was an old (1997) Windows 95 OSR 2 box boasting a P55C Intel Pentium processor with an staggering clock frequency of 166 MHz; 16 MiB of RAM (later expanded to 32), a 1.2 GB* hard disk; it had an onboard S3 Trio64V+ with 1 MiB of video RAM.
* Hard-disk manufacturer ‘gigabytes’.

Then, there was another OEM machine (2002), running Windows XP on a 1.3 GHz Intel Celeron (“Celeron-S”) including 256 MiB of RAM and a 40 GB hard disk; before it was decommissioned for good, it ran both Windows XP SP2 and openSUSE 10.0; it was the first machine on which I ever installed Linux (SUSE Linux 9.3), and my original introduction to Wesnoth (0.9.5 from openSUSE 10.0) happened there; the onboard Intel 810E IGP became the victim of various Linux graphics-related shenanigans. (This was the last computer I ever owned that included a 3.5" floppy disk drive; unfortunately, it was broken and it took me a year and various casualties to figure this out.)

Later during 2006, Blackcore appeared: another OEM machine running Windows XP SP2, equipped with a 2.6 GHz Intel Pentium 4 (Prescott) with Hyper-Threading; 1 GiB of RAM, a 160 GB hard disk, and an IGP from the biggest piece of shit chipset manufacturer otherwise known as VIA. This was my first named computer, a practice which has truly paid off to this day. It currently runs the same original installation of Windows XP upgraded to SP3; it has run various Linux distributions and versions and I’ve not stuck with any of them simply because VIA is the biggest piece of shit chipset manufacturer.

Following the color-themed naming scheme, Greycore became the first laptop I ever owned around mid 2007; an Acer Aspire 5050 including an AMD Turion 64 MK-36, an amount of RAM I don’t remember anymore, 80 GiB hard disk drive, and Windows Vista. It first ran openSUSE 10.2 and openSUSE 10.3 besides Windows for a long time, until I got fed up with an incident involving a security update utterly ruining my system with terrible timing. It took a while before I finally decided to switch to another distribution instead of keeping the same old 10.3 installation around, but it was worth it — Debian Lenny (testing at the time, Q3 2008) was my choice and I have stuck with Debian ever since.

Greycore was decommissioned once Bluecore took over; an HP Pavilion dv5-1132la running Windows Vista SP1. It was a much better deal than Greycore in the long term, as I acquired it on Christmas Eve 2008 and it lasted until January 2011 with mild wearing symptoms until it finally kicked the bucket (it got better later); Greycore did not last more than a year before it got utterly wrecked.

Bluecore started with 2 GiB of RAM and ended up with 4 GiB as Wesnoth began to demand significantly more memory for compiling. The 2 GHz dual core AMD Athlon 64 performed very well at the beginning, but our favorite open source game’s development largely outpaced it. The 250 GB hard disk served me well despite running into low space situations in various opportunities as I began to experiment with the processor’s hardware-assisted virtualization capabilities. This overheating beast (51 °C - 64 °C idle, 65 °C - 92 °C under load) has only run Debian as its native operating system besides Windows — first Lenny (testing, later stable), then Squeeze (testing), and very recently, Wheezy (testing). The ATI Radeon HD 3200 was an infinite source of frustration when it came to OpenGL on Linux until very late 2009.

Its untimely and infuriatingly IGP-driven demise resulted in Reicore taking over; first temporarily, and then permanently as its 2.1 GHz dual core Intel Pentium T4300 and Intel GM45 graphics processor ended up proving far more worthwhile than Bluecore’s AMD-based configuration. Reicore (an HP Pavilion dv4-1624la) was purchased for someone else at first, and ran Windows 7 until she became mine, and then I proceeded to wipe it out to make room for Debian — first Squeeze (stable), and now Wheezy (testing). I have never run out of space with its 500 GB hard disk, and even today my /home partition has a little more than 50% of free space. It helps that the processor’s lack of virtualization capabilities has not been very encouraging in the virtual machine department, I guess.

Notice that Reicore also breaks the naming pattern. This was explained before.

Six computers — that’s quite a lot! I wonder what will come next... (Written wink!)

For my own consideration in the future:

• Bluecore’s DVD drive is ruined and I need to find a way to make the Linux kernel shut up about it.
• apt-cacher doesn’t play well with slow download rate uplinks.
• Dismissing maintainer-suggested /etc/sudoers changes is highly inadvisable.
  

  dpkg: warning: 'ldconfig' not found in PATH or not executable
  dpkg: warning: 'start-stop-daemon' not found in PATH or not executable
  dpkg: error: 2 expected programs not found in PATH or not executable
  

• The Giant Blinking Cursor of Doom has not stopped being a thing that exists and is decidedly annoying and disruptive during reboot sequences.
• Purging grub-pc during unused package removal binges... I have had better ideas.

From a recent topic in Wesnoth.org’s Game Development forum:

[...] this is also quite close to advertisement, but you don't have the traits of a spammer.

This is one of my major qualms about the current organization of the Wesnoth.org forums. The non-indicative Game Development section was indeed created for that specific purpose of serving as a venue for advertising other games and potentially recruiting contributors. The definition of spam for this section is sketchy at best, but common sense suggests that the following forms of promotion would be off-limits:

• Advertising things that are not games
• Blatant advertising by posting links to different topics
• Misleading information/scam

If advertising in GD in general was considered spam, then the forum would be nearly or entirely empty. The question is, why do we provide this marketing channel in the first place? It seems to me like the primary goal is promoting open-source game development, but the forum description implies that this is not a strict requirement for posting there. I am not terribly comfortable with the idea that it should be our mission to do this seeing as how there are larger and better organized communities for this kind of thing, but I can see how some people might prefer to have means to preach to the world at large without having to maintain a blog or register accounts on other boards.

Quite lazy, if you ask me.

But all this is fine by me as long as I’m not forced to read every single topic that crops up in there.

Just as irker’s adoption rate is increasing, I have just completed work on a very simple application for Subversion repositories — two applications, in fact.

irker-svnpoller is a very simple script that polls a single commit log (not data) from a Subversion repository and delivers notifications to any number of channels using an irkerd running on the same host. It mimics the CIA bots’ formatting, much like nenolod’s irker CIA proxy, from which I borrowed a small amount of code.

irker-svnpoller → irkerd

But exactly how is this supposed to be useful to anyone, you may be wondering right now? Well, irker-svnpoller is not really intended to be used stand-alone. A timed poller script that tracks the last notified revision could come in handy, but people could get impatient waiting for their commits to appear in their IRC channels minutes later. I am well familiarized with the defects, quirks, and virtues of my primary audience—the Battle for Wesnoth and Wesnoth-UMC-Dev projects—, and this approach would simply not scale well over time.

Enter the first companion script, svnmail-filter. It reads email message headers from stdin to determine a commit’s revision number and the pertinent repository to probe using irker-svnpoller. Configuration is mostly done through a ruleset file using the JSON format.

Of course, svnmail-filter is not that useful on its own either. The idea is that procmail or some other MDA should pipe incoming email headers through svnmail-filter — and preferably, only those from legitimate sources, such as subscribed commit mailing lists. This is actually simpler than it sounds, and it is more or less inspired by CIA.vc’s perpetually broken mail-based SVN poller.

MDA → svnmail-filter → irker-svnpoller → irkerd

Since no service in the pipeline other than irkerd runs persistently in the background, this should be significantly more fault-resilient than CIA.vc’s approach, which apparently required a poller service to listen and act upon local requests. The downside is that the host running irker-svnpoller may need to create many short-lived SVN repository connections for individual commits in a chain. In Wesnoth’s case, SVN commit chains are rare enough, but their size often goes around a dozen individual commits or so. Regardless, this shouldn’t be terribly concerning for a production server with a decent low-latency uplink, and the overhead on the repository provider should be rather small compared to pushing massive commit diffs across the network.

Right now, the Wesnoth and Wesnoth-UMC-Dev projects are using this service as a stopgap measure until their respective providers—Gna.org and SourceForge.net—allow installing a hook that can either talk directly to an irkerd server, or to an instance of the aforementioned CIA proxy using the CIA XML-RPC method.

I am not all that keen on other people using a piece of software I developed and tested within less than three days without any prior experience working with Python. There are also various problems inherent to any application depending upon Subversion and its incompetent network transport layer.

Nonetheless, I published a Git repository on GitHub including a small amount of documentation to get started:

• shikadilord/irker-svnpoller on GitHub

I am open to possible improvements coming from people intending to use this on production servers. In particular, if someone out there works with a commit mailing list where revision numbers can’t be found in mail subjects it would be necessary to adapt svnmail-filter a little to handle that case. Perhaps it might even be possible to skip the irker-svnpoller step for mailing lists where the notification message structure is constant and well documented.
