Oops, isquared.nl had some unscheduled downtime last night after the telltale signs of a dying disk:

Jun 28 01:09:07 c3 kernel: [  184.700869] hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Jun 28 01:09:07 c3 kernel: [  184.700869] hda: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=20586, sector=20407
Jun 28 01:09:07 c3 kernel: [  184.700869] ide: failed opcode was: unknown

One emergency dd to a disk, stolen from my old TV set-top box, later and we're up and running again.
Only a shame that due to the layout of the partitions on the dead disk, I can't grow my filesystems easily to make use of the much larger disk that is transplanted to the server.

"NS zet bussen in" is een iCal feed gemaakt van de aankondigingen van werkzaamheden op de NS website.
De aankondigingen op de NS site zijn slecht te lezen door computers, ik heb geprobeerd deze zo goed en zo kwaad mogelijk om te zetten naar "all-day" events.

De feed is beschikbaar op http://isquared.nl/nszetbussenin.ics, deze feed is (bijvoorbeeld) in Google Calendar als gedeelde agenda toe te voegen. Op deze manier weet je de volgende keer vooraf of er werkzaamheden zijn op weg naar de afspraak die je probeert te maken.

The tag cloud on the left side of this page displays tags assigned to articles. The size of each tag is determined on the number of articles to which this tag is assigned.

I was interested how this tag cloud looks like when the size is determined by the popularity of articles tagged with a certain tag among readers of isquared.nl.

To visualize this I have hacked together a quick application, called TagPop, to display the tags based on popularity, this is available here.

In a later post I will write more about the inner workings of TagPop.

Since the new site is built somewhat like a blog, I'll repost the old content as blog entries from here.

Welcome to the new design for isquared.nl.

The old layout didn´t render properly on some browsers and wasn't too user-friendly anyway. So I decided on less form over function and tried to make it a bit easier to maintain at the same time.

This is still a work in progress, so some features may misbehave or don´t work at all, this should be fixed soon, depending on my spare time. ;-)
