What a cool Christmas gift!

As many of you know, I’m active in BOINC. One of the projects I participate in is PrimeGrid. It’s a project that helps search for prime numbers of certain types. I don’t even pretend to understand the math. I just know a prime number is one that is only divisible by one and itself (for example 3, 5, 7, 13…).   There’s a bunch of different sorts of special primes that correspond to certain formulas.  But like I said, I’m not going to even pretend to understand the intricacies of the math.  I’ve been an on again, off again participant for over a year now. I come back to it for two reasons. First, the work units themselves are short (at least for the subprojects I’ve chosen). And second, Rytis, the project administrator is a genuinely nice guy. He’s a college student in Lithuania and his English is probably better than mine.  We chat via IM at least a couple times a week.

A few hours ago, I noticed I had gotten an email. My in box has been pretty quiet over the last few days because of the holidays so I was surprised to see the email. I was even more surprised to see that I (well, my computer) had discovered a prime big enough for inclusion in “The List of Largest Known Primes“.

My prime is 28739399349*2^333333-1 and contains 100354 digits. It’s currently ranked at #4306. When I submitted it, they estimate that at the current rate of prime discovery it will remain in the top primes list for approximately 10 weeks. So I guess I get 10 weeks rather than 15 minutes of fame.

Just for fun, I took a screen shot of my current certificate of computation.

Merry Christmas!

I want to wish all my readers a Merry Christmas and a Happy New Year!

I’ve included some of my favorite songs and clips from classic Christmas shows. Enjoy!

Holiday Pictures

It’s taken me a while, but I finally managed to remember to take pictures of my holiday decorations. Enjoy!

Theme change

Holiday time.  I’m trying to get in the spirit.  So I’ve changed over to this theme.  Everything that was in the sidebar is now on the bottom.  I need to figure out if that’s how it’s supposed to be, or if I’ve got something that’s too wide pushing the sidebar down.

I have my Christmas tree up and decorated.  I hung Christmas lights.  I made an Advent Wreath.  OK, so I stuck four votive candles of the proper color into a plastic grass mat.  But that’s the closet I’ll be able to get to a wreath here.  One of these days I’ll actually take some pictures.

Speaking of pictures, I just need to download the pictures from my camera of November’s birthday Friday.  I guess I should add that to my to-do list.

It may or may not get done this weekend.  I need to finish my portfolios.  And I have a software package I want to compile.  I know that it will compile without error with the default settings.  Now it’s a matter of tweaking the configuration file to get it to compile with processor specific optimizations.

More computer adventures

It’s no secret I’m actively involved with BOINC. I’ve learned a lot about computers from running their software and helping out in the various project forums. It was one of the project administrators that so kindly helped me get Linux up and running on my computer (current uptime 15 days, 10:07 and still going strong). Because running BOINC tends to stress your system, I was looking for a lightweight monitor for things like memory usage and temperatures. I know all about top to get processor/memory usage, but having nice little program with everything in the same place is preferable. So I found Conky.

If I had Debian or Gentoo or just about any other Linux distro, I would have been free and clear because there are pre-compiled packages. But of course there wasn’t an rpm for it (I use Fedora 7).

Compiling from source was supposed to be as easy as configure, make, make install. Note the use of the term “was supposed to be”. I guess if I actually had my system set up as a development box (and I actually knew slightly more than nothing) it would have been easy. My experience with compiling from source was limited to mplayer and that basically just worked (once I got g++ installed).

I knew I was going to need the X11 development libraries so I installed those. I bravely opened up the terminal (actually I’ve gotten quite comfortable with it) and unpacked the source archive. I changed over to that directory and told it to go do the configure. I watched it churn away and spit out an error. Grumble grumble grumble. This was a few weeks ago. I asked a friend for help, but he wasn’t familiar with the libs. I Googled. No joy. Nothing looked relevant and what I read went so far over my head that I needed binoculars to see it. I posted on the Conky forums, but no response. So I put the whole project on the back burner for a few weeks.

I was bored this morning and decided to see if anyone on the BOINC forums might know where I needed to go from where I was. Within thirty minutes I had a response. Thank you Trog Dog! Just by seeing what I needed to install I also saw how to read the error message. So I installed what I needed and ran configure again. Another error. So I downloaded and installed some more developer stuff. Later, rinse, repeat about three more times. And then the configure succeeded. Yippee!

Make and install went flawlessly. I ran the program. And BINGO! I now have Conky on my desktop.

Conky

Now I have some reading to do on how to best configure Conky for my use. What is shown in the picture is the default configuration. But after getting it compiled I needed to go and finish my grocery shopping. So that little project will have to wait for another day.

Pictures!

I had written a few weeks ago that I was having issues with the service I chose to host my photos.  I never managed to find a way to get in touch with the folks and the forums were less than helpful.  I can’t complain too much because I had a free account.  So I found a new service.  I don’t even remember what I was reading, but I came across webshots.com.  The free account isn’t a bad deal.  You get 1000 photos initially and then an additional 100 photos per month of storage space.

Uploading isn’t too bad on Windows.  Supposedly there’s a desktop program you can download.  Doesn’t do me much good with my main box being booted into Linux 99.9% of the time.  The web uploader crashed Firefox in Linux reliably, but it worked fine on Windows XP.

To get my photos uploaded without going back to Windows on my main box, I learned how to mount my XP’s computer’s hard drive as a network share.  I backed up all of my photos to my XP box (a good idea any way) and used the web uploader from there.

To make a long story short, all my photos are now posted.  Yes, all 706 of them.  They can be found here.

Yes!

GRUB has been whipped into submission. I now have a fully functional, triple booting laptop.

It was hard getting to this point. Typos are the worst. But I found one on my own and my tutor found the other one.

For the curious, my grub.conf looks like this. I removed my name for privacy.
