Venus transit approaching / clouds?

June 3th, 2012

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.
