Wardriving results for 27 - 29 April: 66 new networks with GPS. No purpose wardriving done, just minor detours through Utrecht.

Wardriving results for 25 - 26 April: 294 new networks with GPS. Most of those from a tour through Lombok, an older part of Utrecht. Lombok has its own Internet provider which started in 2003 with wireless Internet (site in Dutch), which is now moving towards connecting homes via fiber (site in Dutch). I can imagine they have interference problems in their wireless network with hundreds of access-points.

Wrote a bit on how I configured FreeBSD as a PPS slave.

It seems Google used this map upgrade to signal developers that the Google maps API was upgraded recently to v2. So I followed the instructions about the upgrade to v2 for my loc2map script and now I can see that Surfnet, the Internet provider for higher education in the Netherlands, puts their routers in a wheat field in Rotterdam or under the trees in Amsterdam (zoom in to the deepest level). Ok, the LOC RFC says you can give coordinates 'in the area' and update the 'horizontal resolution' accordingly. It still looks funny.

Hey, Google maps has been updated for the Netherlands. Clear Satellite images of constructions close to where I work and detailed maps. I hope they make this data accessible for google maps api soon, because I still get 'lower' resolution satellite images and maps that say 'the Netherlands exist' in my simple google maps api application. For the black helicopter crowd: Naval base 'Kattenburg' in Amsterdam.

The latest in wheelchairs which takes into account that wheelchair users do want to get off the paved road: an All-Terrain Wheelchair built by the Fraunhofer Institute for Information and Data Processing IITB and Otto Bock HealthCare and the Tank Chair which does indeed look like a one person tank.

Ik heb voor de hcc!pc netwerkgroep een blog opgezet met serendipity, eens kijken of dat gaat werken. Ook heb ik beschreven waarom ik serendipity gekozen heb.

Configuring the NetApp continues. Basic configuration has been done yesterday and now I'm playing with it myself. Trying to understand everything, hoping to make it do what I want. So far I got ldap userlookups working after several tries (for multiple ldap server names, put a comma and(!) a space between the names.

Wardriving results for the period of 11 April to 19 April: 910 new networks with GPS locations. A bike ride through another part of Leidsche Rijn got me 451 new networks. Otherwise small and larger detours through parts of Utrecht where I was before, which usually give me 20-50 new networks each.

Today at work was 'My First NetApp' day. A NetApp engineer came over in the afternoon to help with the rackmount and the initial installation. Since the initialization of the disks was going to take longer than planned, the rest of the installation will be done tomorrow. I am eager to work with the NetApp, hoping it will improve the response time of the home directories (main reason we started looking for new storage). That is the first bit we hope to be able to bring on-line. Later we will look at other storage that we can move to the NetApp.

Aanpassing aan het artikel over marketingsnake. Ze heten nu green-advertising. Verder exact dezelfde manier van werken.

Speaking of FreeBSD and ntp: yesterday at work I set up a Dell Poweredge 2550 as ntp server. FreeBSD 5.4, a kernel with PPS support (the PPS bits will arrive when I have time to make a cable). It now runs over the weekend to see how stable ntpd will get.

Another problem with a public NTP server: Poul-Henning Kamp runs an NTP server on the Danish internet exchange DIX. He found out D-link routers all hammer on that NTP server (and lots of others) without any prior agreement. Read his Open Letter to D-Link about their NTP vandalism and Richard Clayton's write-up on how he researched the problem and found the source in the D-Link equipment. NTP was one of the last services that you could run cooperatively and assume your clients would play nice, now with 'home broadband routers' everywhere out in the world who like to keep the right time (and use sloppy-programmed client software to get that time), this trust in cooperative clients has been broken several times. Yes, this looks a lot like the former case with the University of Wisconsin - Madison and Netgear routers. At least, that case was solved with a good fix and an apology from Netgear.

Wardriving results for the period of 29 March until 10 April: 398 new networks found with GPS. Most of those when I had to be in the city center and walked a number of back streets between the place I parked my bike and the place I had to be. Not a lot of wardriving happened otherwise because of a busy schedule and other things to do (like marriage preparations).

Het lijkt wel recent of Duitsland het nieuwe land is om spam vandaan te sturen naar Nederlandse Internet gebruikers. Nadat ik eerst ontdekt had dat marketingsnake spam verwees naar een in Duitsland gehoste website valt het me nu meer op. Shirtcity, ook gehost in Duitsland lijkt het gewoon leuk te vinden om naar een random opgegeven mail adres mail te sturen en meerdere pogingen tot unsubscribe en klachten bij providers niet te zien als reden om daar mee te stoppen.

Typed a bit about the web form spam attempts that I have seen today.

Several times I received e-mails asking for links on this site to sites with sex toys (all people with websites get link requests probably, I just get weird ones). But, sofar, nobody told me what page exactly made them request a link. And when I asked in reply which page made them ask for that link they went 'uh.. link to us from any page!' which was not a usable answer. This weekend I got a request that was specific enough, they wanted a link from the Friday afternoon link page to their webstore. Just a webstore, not a real good Friday afternoon page. Ehm. No.

Wardriving results 25-28 March: 278 new networks with GPS, 3876 total according to WiGLE. This included some walking through the center of Utrecht. Where GPS reception does fail sometimes, especially indoors...

I'm trying to reinstall windows 98 on one of my fathers oldest computers (a Pentium-75 with 96 Mb memory). This turned out to be more of a 'fight' than usual. The first harddisk has 2 partitions and uses PowerQuest Bootmagic to help them boot. I wanted to make an extra copy of the data on the DOS partition, so I wanted to boot the PLD rescue CD. Which shows up as bootable when this system boots, and then it skips this option and still boots from harddisk. Another bootable CD boots ok. The PLD rescue CD has an image of a floppy that can boot anything using Smart Bootmanager. So I start finding a floppy that is usable enough to boot that image. After several tries that works. I find out that the default settings of the PLD rescue CD don't work on a machine with slightly less than 96 Mb mem (yes, an old computer), correct bootoption: la. So, finally I was able to make a copy of the DOS partition. Next bit: trying to convince the windows 98 setup to only play with the windows 98 partition. It really wants to install on the entire first disk (yes, the monopoly position behaviour we know Microsoft for) but I fixed that by changing the partition type of the DOS partition to 'non-FS data' (type 0xda) using the fdisk tool on the pld-linux cd. And.. succes.
