On the 12th my provider M-Net will activate the DSL link. I've taken the 12th
and 13th off work so that I can hook everything up at home. I'm worried of
not getting back my static IP, which I had for 4 years. I let M-Net know this
but haven't had a reply from them yet. Not getting the static IP will not be
the end of the world, but the end of e-mail, www, shell server and other stuff
at home. I truely hope I get my static IP back though, and will fight for it.

Let's start with my computer for cooling. :-) The fact that this was
developed in China is cool too because most computer parts come from there...

Then here is a series of chips to consider.
Jupiter is currently an i7-930, but an i7-980 would be nice but is still pricy,
with 3 years warranty however it would give 6 year lifespan of the
3 year old
machine perhaps. I'm watching for the price for the 970/980 to come down.
I'm also considering what tasks I want running on Jupiter. Right now there isn't too much CPU intensive stuff. Also Jupiter never ran over nights. I turn it
off at night and plan on continuing to do so.

My blog and other data stored on my VPS's can be examined by the NSA through
the american hoster I use. This is cautioned by the BBC. Particularily falls the VPS in Hong Kong
then under jurisdiction of the NSA because I use an American provider based in
Los Angeles. The VPS in Panama is operated by a canadian company and they
probably have similar laws. So my data is wide open to the american
contintent. I do not know what sort of information they would like to gather
though other than web and dns logs. In terms of juicyness my blog doesn't
have very much worth spying over. But I thought the article in the BBC was
intriguing nontheless. I'm not going to pull back my blog over this though.

The BBC has an article about the NAP of the Americas in Miami, USA.
Here it is.
The NAP is what most routes from Germany go through when I traceroute
my Panamanian VPS. Interesting building, it reminds me a little of 151
Front albeit much larger.

I joined IRC in 1994 or earlier. The very first time I used efnet chat network
was when my BBS provider had a door to ircII client or something. There I
first hung out in #linux or #linuxhelp and someone helped me upgrading/compiling
from Linux 1.2.3 to 1.2.13. I left IRC at that and was MUD'ing on ncmud for
a long while but when I noticed a slight addiction I left MUDing. IRC was the
addiction to heal my addiction.
I spent time in the channels #unixhelp, #unix,
#toronto, #germany, #bork, #freebsd, where some more and some less. I was
very taken with the #unix crowd and liked being there but admittedly I was
always a bit careful because of the chance that I get hacked by someone there
(it was a large channel of 100 or so clients). Eventually I left #unix and
went totally offline (from the Internet) when I had a new toy. An iBook with
built in wireless lan. I spent the Summer of 2000 mostly outdoors riding
around wardriving with it.
The wardriving did me no good and I eventually came
back online and this time not to #unix but #unixhelp. There was people from
#unix there so I knew some people. To this day I IRC on efnet and IRCnet on
the channels #unixhelp, #bluenight and #dns. More on this all later.

In Germany the electric grid is becoming more and more decentralized. Solar
and Wind powerplants are being created in every region. Wouldn't it then also
make sense to also decentralize the computers in germany? I read of all these
supercomputer centers, datacenters around regions that serve as Internet hubs
that they are having problems getting guaranteed energy, mostly to cool their
arrays of server racks. What we need is a distribution of high speed Internet
access and put large computers to use at home on a distributed computing effort
in my opinion. These computers don't need as much cooling as centralized
computers in data centers, saving energy.
PS: I'd like to get away from moving fans to cool computers but rather use
LASERS to do that.
So who serves your mail? Perhaps we all need static IP's too, face it
privacy is gone anyhow, with static IP's we can receive our own mail and not
need large datacenters (and the complexity involved).

My time machine backup is really slow. It's been backing up 1.5 days now across
two nights and only did 38 GB from 282GB to back up. The drive that it's
backing up to I timed with dd command to be writing 121 MB/s (roughly twice of
what USB2 is capable of) so it doesn't seem to be a speed issue. iostat is

Let's see 2MB/s at peak for one second out of ten and on the computer is 96%
cpu idle. Something is surely wrong.. I suspect it's doing a lot of small
files but even then..
I'm at a loss and googling for solutions isn't working either.

Usually I always buy a backup drive right away. However planning to buy a
new wireless timecapsule didn't work out because I'm still expecting apple
to release an 802.11ac access point. The current models are 802.11n and less.
But since the capsule is only 100 or so euros more than the airport extreme,
I'm gonna go with an extreme instead and plug this new harddrive into it.
I bought a 2TB external harddrive btw. This will be enough to back up my
mac mini with timemachine.

I noticed that typing control-left arrow and conrol-right arrow can switch
between main screen and vmware guest. This is fancy and quick. I personally
go from OpenBSD to Mac OS X between work and personal time.
