Ubuntu Precise Pangolin Update Issue with LibreOffice

If you are among those brave (foolhardy?) enough to have already updated systems to Ubuntu’s Precise Pangolin, you may have encountered the following error while updating your system over the last 24 hours or so: Errors were encountered while processing: /var/cache/apt/archives/libreoffice-core_1%3a3.5.0~beta2-2ubuntu2_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) Fortunately, there is a relatively easy …

Ubuntu Precise Pangolin Update Issue with LibreOffice

If you are among those brave (foolhardy?) enough to have already updated systems to Ubuntu’s Precise Pangolin, you may have encountered the following error while updating your system over the last 24 hours or so:

Errors were encountered while processing:
/var/cache/apt/archives/libreoffice-core_1%3a3.5.0~beta2-2ubuntu2_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Fortunately, there is a relatively easy fix. I am not sure exactly what is causing this, but it occurred on two of my systems yesterday, and still this morning on a third. Initially I thought it might have occurred on the one system because it has been upgraded through several releases, but when it started occurring on freshly installed systems that idea went out the window.

Regardless, the following commands should help get your system back on track.

sudo mv /usr/lib/libreoffice/basis3.4/program/ /usr/lib/libreoffice/basis3.4/program.old
sudo mkdir /usr/lib/libreoffice/basis3.4/program
sudo apt-get install -f
sudo mv /usr/lib/libreoffice/basis3.4/program.old/ /usr/lib/libreoffice/basis3.4/program

Good luck!

Verizon 4G MiFi Quicktest

Categories:

Got my hands on a Verizon 4G LTE MiFi device to test today, so of course the first thing I did when I got home was a quick Speedtest.net check on it.

First, a test of my Time Warner RoadRunner:

Roadrunner Speed Test

Not bad on the download side, though one important thing to remember is that this speed is largely based on the burst technology Roadrunner is using, and that speed is only good for the first 16 seconds of a download or so, at which time it drops to roughly half that speed. Therefore, since this download fits within those 16 or so seconds, the speed is greatly inflated over what a larger download would have shown.

And not unexpectedly, the speed test shows the anemic upload speeds which has plagued Roadrunner connections from the very beginning. I was actually surprised to see even this number.

Now for the Verizon numbers:

Verizon 4G LTE Speed Test

Verizon 4G LTE Speed Test

As you can see, the download speeds are roughly equal, which in reality is an amazing feat given that this is wireless broadband versus a cable connection. The other thing to remember is that these speeds seem to hold steady across an entire large download and do not drop off like the Roadrunner speeds do.

On the upload side, the Verizon MiFi simply crushed the Roadrunner speeds. Given that we plan to use these to upload mobile video, this will be a critical number if it holds steady throughout the region.

I gotta say, I am really impressed by this thing, though we’ll see how true that is after I test it in a variety of locations.

This will give the USAF Space Command one more bird to control and those of us from SeeSat-L one more to track.

I started participating in the Free-DC Prime Search early last week, and early last night I received a Notifo popup on my iPhone that the computer currently checking for prime numbers had found one:

7435\times 2^{749431} -1

This yields a number which is 225606 digits long and which currently (though likely not for long) is in 1543rd place on the list of the 5000 largest primes.  The prime has its own page on that site and bears the registration number 97197.

The New Sherlock

Categories:

by

Two men who couldn’t be more different — united by ADVENTURE! Blowing away the fog of the Victorian era, the world’s most famous detective enters the 21st century.

If you are even a modest fan of the Sherlock Holmes character, you owe it to yourself to catch the new episodes of Sherlock now playing on Masterpiece Mystery!

Set in modern London, the young chap playing Sherlock is one of the best I have seen, and he has captured the essence of a younger Sherlock perfectly. While I was at first leary of a modern Sherlock, Benedict Cumberbatch (as Sherlock) has swept aside all concerns and brings something to the role that I didn’t think was possible since the passing of Brett.

If you liked the movie, this may not be for you. But if you like the Rathbone or Brett Sherlock’s, then give this a try. Series 1 consists of three episodes, the last of which is playing tonight (7 Nov 2010), but I believe they are also already available on DVD.

National Park Week 2010

National Park Week will run from April 17th through the 25th this year.  Entrance to all 392 national parks will be free for that week, so now is the time to start finalizing plans for that great expedition.  Throw on the backpack and mosey on down a few miles of trail, or break out the Trek Light Gear hammock and cosy up to a couple trees for some R&R time amidst the sounds of nature.

Happy Pi Day

Categories:

by

For those who understand such things: Happy Pi Day.  I rarely jump on the bandwagon of all of the various X-days that have come and gone recently or which are coming, e.g. 10/10/10, but since Pi is such an interesting beast, it just needs to be celebrated on its day.  Question is: How does one properly celebrate Pi Day?  Sit down with your favorite math book?  Hug a math nerd?

Anyway…  I really like some of the other suggestions for Pi Day proposed on the Real Pi Day site.  Hopefully a consensus will be reached and banks and government employees can begin to have a day off in honor of the holiday.  And in case anyone is listening, I vote for the day/time when the sun has travelled 1/pi from perihelion.

Craig on WRALCongratulations go out to my brother who was named national Technician of the Year by the E9-1-1 Institute.

More information appears in this story on the WRAL website.

Love the quote: “Through his leadership, the emergency communications IT team and the communications-electronics maintenance shop have made great strides toward enhancing the reliability and affordability of a wide variety of technology,” Furey said.

Now I’ll probably need an appointment to talk to him on IRC.
