On June 8th, 2004 I was at my parents house and my mom and I looked at the
sun in a very rudamentary way. We held binoculars at the sun and used a
sheet of paper on the other end to make out a tiny dot that was venus. Never
look directly at the sun, or you'll have sight problems later. So on June 5th
and 6th (depending where you are) Venus will transit the suns disk again and
supposedly we won't see this event repeating from happening for a few
generations, so it may be worth it to take a look. It looks like we'll have
clouds here but there is a chance for it to clear up.
All sorts of telescopes will study venus from earth as the atmosphere will
likely be illuminated by the sun and we'll see details of how thick the
atmosphere may be. Who knows, there may be other science experiments that
could be done. Have fun to anyone looking at this solar system event. Also
have fun reading about it on the Internet, the best virtual telescope on
earth. I know I will.

Home network fully at OpenBSD 5.1
June 2nd, 2012
This morning I upgraded uranus to 5.1 and it took about 2.5-3 hours with all
the packages being upgraded and such. This is usually such a pain that I
don't want to run -current and wait for the OpenBSD releases every year.
Oh yes I also upgraded libcrypto after the errata for 5.1.

Ordered 4 books (I know, I know)
May 27th, 2012
Now that I'm making a fairly good income I gotta put my money somewhere so
I invested it into education. I bought four books that will help me with
my trait. One of them is:
Building Telephony Systems...
I think SIP phones are going to be with us for a long time to come. My
Grandstream even hinted that it can do IPv6 now, which I have to play with.
Oh well.

What to do about ports?
May 23rd, 2012
I had moved /usr/ports to /usr/local/ports because it didn't fit anymore.
And today I ran out of space on /usr/local.

At that point I unfortunately had to kill the typescript since it was on
the /usr filesystem and I needed to unmount it. What I did was something
along the lines of.
umount /usr
disklabel wd0 # and do some math
export EDITOR=/bin/ed
disklabel -e wd0 # and forget some commands, but it came back to me
newfs /dev/rwd0f
cd /usr ; restore -xf /mnt/backup/j-usr.dump # I backed up those before hand
cd /usr/X11R6 ; restore -xf /mnt/backup/j-usr-x11r6.dump
vi /etc/fstab # take out the old parititions
shutdown -r now
In the end my partitions looked like this and I was able to continue building
ports in /usr:
jupiter$ df
Filesystem 512-blocks Used Avail Capacity Mounted on
/dev/wd0a 2057756 125456 1829416 6% /
/dev/wd0d 8250780 236 7838008 0% /tmp
/dev/wd0f 26829980 14103900 11384584 55% /usr
/dev/wd0k 209124908 83352904 115315760 42% /usr/local
/dev/wd0j 4122108 321792 3594212 8% /usr/obj
/dev/wd0i 4122108 1694272 2221732 43% /usr/src
/dev/wd0e 38273692 65532 36294476 0% /var
Putting the ports in the right directory is becoming a real problem for me.
And I've put some security of my system at risk because I took out some
compartmentization.

What's up? Nothing.
May 21st, 2012
May,2012 is probably the least contentious (if that's a word) month in this
blog's history. I'm busy working and haven't found anything worth putting up.

io.solarscale.de needed a rescue/fsck
May 11th, 2012
Today io.solarscale.de acted real weird. The filesystem turned read-only on
me. So I rebooted the vps. When it came back it suggested fsck'ing the
filesystem. So I rebooted it once more hoping that it would fsck on boot.
It didn't do that. So I learned from my VPS provider how to put the system
in a rescue mode and finally I was able to fsck the hd image. The system
is debian and the particular filesytem is ext4 with journaling. For some
reason it would mount rw before the second reboot but still manage to say
it needed to fsck, how cocky! Anyhow. Everything seems sweet now. And
I may have learned how to install FreeBSD on this vps too. Shall the time
ever come I may do that.

OpenBSD 5.1 released, jupiter.centroid.eu built
May 1st, 2012
OpenBSD 5.1 has been released today, at least I found the OS on the ftp.eu.openbsd.org ftp server.
So I wiped my vmware setup and installed it on the 160 GB SSD. Here is a
paste from the top while playing a youtube video:
load averages: 0.98, 0.91, 1.00 jupiter.centroid.eu 14:14:43
56 processes: 53 idle, 1 zombie, 2 on processor
CPU0 states: 11.6% user, 0.0% nice, 4.8% system, 0.0% interrupt, 83.6% idle
CPU1 states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle
CPU2 states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle
CPU3 states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle
CPU4 states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle
CPU5 states: 4.0% user, 0.0% nice, 0.8% system, 0.0% interrupt, 95.2% idle
CPU6 states: 13.2% user, 0.0% nice, 8.8% system, 0.0% interrupt, 78.0% idle
CPU7 states: 11.6% user, 0.0% nice, 9.8% system, 0.0% interrupt, 78.6% idle
Memory: Real: 269M/958M act/tot Free: 6994M Cache: 575M Swap: 0K/7353M
mostly idle. This thing is a beast. Yes I did turn on HT again to see if the
lockups were confined only to Linux. I had another 80 GB SSD which I have now
put to rest until I need a replacement SSD. Also I tried gnome but it didn't
work so I'm back to using fluxbox which is fine with me.

Wildcarddnsd, pondering hacking again
April 29th, 2012
Well I had a really long break from hacking on wildcarddnsd. While reading in
this SIP book (see below) I noticed that the SRV RR is not supported by W.
So I'm thinking of putting that in. Anyone interested in helping with this?
Other little hacks are moving the command line flags to options in the config
file. If anyone is interested in doing that go right ahead! If you want a
bigger challenge I need a replacement parse.c file that is nicer perhaps a
YACC file (no bison!). What's on the menu for the long run? Well I hope to
be getting some time to do DNSSEC sometime in the next 2 years and also the
recursive resolver function I'd like to re-implement as this one is currently
broken. There is lots to do you just gotta look for it.

BOINC processing coming to an end
April 29th, 2012
In this article
I wrote about increasing boinc from 1 to 2 cores. It has been doing that
since February 2nd. So all good things come to an end, they say and it is
without regret that I'll be ceasing my processing probably around May 2nd. So
I had done 3 months of processing on 2 cores. OpenBSD Europe has started
shipping OpenBSD 5.1 and I fully expect my copy to get here tomorrow so that
I can start installing Jupiter with OpenBSD. In this other
article
I wrote about being in spot 142,597 well I'm happy to report that I'm now in
spot 97,043 so in the top 100,000. And also in the top 5% of BOINC participants. I think it's a job well done and I also paid for it with my electricity
bill. At least I gave something back for science.
