More to follow: wikis without nofollow

I've come to realize that it's silly that most wikis are using nofollow by default. In fact, it seems that the majority of the most visited websites are not contributing to a healthy way for spreading pagerank. Twitter, Facebook, Flickr, Youtube, Wikipedia and Delicious are all adding rel="pleasefollow" to links added by their users.

We're working on 73 pages. If this number somehow bothers you you are very welcome to start a new page. is a wiki about cults.

Underscores to dashes in MediaWiki (not yet)

It's clear that dashes (-) are better than underscores (_) for search engine optimization. So people have looked for ways to make MediaWiki use -. Wikihow is one of the few MediaWiki sites that behaves this way, but unfortunately even they don't seem to be running an extension for this. I tried my luck at changing the MediaWiki core (Title.php) but I'll leave this for now.

Back in A'dam

My unlimited MetroCard was still valid for a day and a half so I left it to the poor soul who was robbed from all of his belongings in Lower Manhattan - he was also staying at my host's place in Williamsburg. I had a good flight to Dublin, where I had a very pleasant stay with Dublin's superhost. The guy has been hosting more than 1000 people. Now I'm back in Amsterdam, and it feels good to be among friends. It was just a bit annoying to find out that a "1 zone" tram ride in Amsterdam costs 2,60 euro these days. I boycotted that and walked instead - with about 25 kg of extra weight.

Out of New York and into Groundcrew

I'm in Northampton MA right now, at Joe Edelman's place. It's nice to be out of the City. It's even nicer to see Joe excited about Groundcrew. The guy who worked on the user interfaces for Blogger and Twitter is doing the design and there are some cool opportunities. It also looks like the project has taken a clear direction on one side - while leaving open the community side for later. The main problem is the cost of text messages, which should have been free by now.

Logos for wikis

I'd like to see some logos for the following wikis: Healthywiki, Visawiki and Wikifurniture. Let me know if you think you can make something nice, or even better, you can directly upload it to the wiki. And yeah, anything is better than nothing at all.

Silly with rsnapshot

A bit silly. I tried setting up rsnapshot to make snapshots of the entire filesystem on my server. This apparently led to a fatal exception in the Linux kernel, probably when rsyncing /dev and especially /proc. It took a bit of time before it was fixed, but everything is working fine again. I'll make sure to first try silly things such as backup / localhost on my laptop.

fail2ban and sshd on non-standard port

Sometimes wifi connections only allow connections to a limited range of ports. In Israel connections to ports over 1024 were seriously throttled. So I put the SSH server of one machine on port 22. When going through /var/log/auth last week I found many bots trying to enter with standard names. So I installed fail2ban, today I'm checking and everything is working fine. For your own safety you can set up IP addresses that can always come through. Merely putting sshd on a non-standard port seems to be a more adequate way to keep bots out.

My wikis - a couple of new ones and a tiny reflection

So yeah, I tend to start wikis all the time.  The past months have been no exception.  Marc had been talking a lot about "Cultwiki" (or at least about cults in various forms) so while in Israel I took a little moment and set up Cultwiki, which so far almost hasn't seen many edits - I'm not really that interested in cults myself  - or well, to think about why a specific group I like or don't like is a cult.  But maybe you are just as interested as Marc?  I also set up

Working on Backups

Today I got myself a new portable 320 GB harddrive. I've been setting up rsnapshot for some time machine like backups, both from my laptop as well as from my Hetzner server. Now I'm hoping rsnapshot will also properly run under cygwin so it can run on my brother's laptop with a future Lacie RAID 2TB Hard Disk MAX, for extra data security with RAID 1. P.S. Rename USB drive in Ubuntu.
