Sideling Hill Road Cut by I-68 at Maryland

A week ago I was at the trip to Washington, D.C. to pick up a new passport. On my way there was a sounding Sideling Hill ( http://en.wikipedia.org/wiki/Sideling_Hill ), cut by two by the Interstate 68 ( http://en.wikipedia.org/wiki/Interstate_68 ). I was impressed by the sightseeing and made a few photos:


Douglas SBD Dauntless @ Chicago Midway Airport

At Chicago Midway Airport I found a memorial, dedicated to Battle of Midway with Douglas SBD Dauntless as its central part. I was unable to stop myself making photo by photo! Enjoy!

Photos from trip to Chicago, IL

And another bunch of traveler's photos. These are from my trip to Chicago, IL at 06--07 of September to participate in 2013 Midwest Theory GetTogether.

BTW, Google+ joined few photos to make a sounding panoramas. I found it interesting.

Photos from a car trip to Washington, DC

Hi All,

Hope, this post find you well. At 24--25 of July I made an exciting car trip from Athens, OH to Washington, DC. It was my first long-range driving experience. Here are the photos I made during this trip:



Switching between OpenJDK v.6 and v.7 in Debian 7 Wheezy

In Debian 7 Wheezy for the architecture amd64 (most of the modern 64-bit architectures) the default OpenJDK is OpenJDK v.6.

But what if you want OpenJDK v.7 (Java 7)?

Debian Wiki ( http://wiki.debian.org/Java ) already have the answer, what and how to do, but this answer mining should take you for a while...

Here is the howto.

First, open the terminal and
$ su -l

Now install the JDKs:
# aptitude install default-jdk default-jre openjdk-6-jre openjdk-6-jdk openjdk-7-jre openjdk-7-jdk java-common

This will take you for a while.

At Debian 7 the default JDK/JRE version is managed by the 'alternatives' system. So, to list the available (installed) JDKs, type:
# update-java-alternatives -l
The output will be like this:
java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64
java-1.7.0-openjdk-amd64 1051 /usr/lib/jvm/java-1.7.0-openjdk-amd64

Now let's switch to Java 7:
# update-java-alternatives -s java-1.7.0-openjdk-amd64

That's all!

Please, check the Java version:
$ java -version
$ javac -version
In both cases, the versions should be like 1.7.*



Way from Athens, OH to College Station, TX @ 2013-03-02

Hi all,

https://plus.google.com/photos/114763874066147257538/albums/5890960614150781649 - Here are the photos, I made on the way from Athens, OH to College Station, TX at 02 of March this year.

It was a sounding jump from the winter to the spring in one day! :)

Installing Skype at Debian 7 'Wheezy' for AMD64 architecture

Hi all,

About a month ago Debian Community released the long-awaited Debian 7 'Wheezy':

It includes a lot of new features. The most notable, of course, is GNOME 3 user interface. It's amazing!

Skype at Debian 7

Most of the user computers now are 64-bit machines (usually everything works fine with AMD64 version). But Skype provides binaries only for 32-bit architecture (i386). Fortunately, Milti-Arch support at Debian solves this problem!

Debian Wiki page about Skype ( http://wiki.debian.org/skype ) is written in a too complicated way. It took me a while to understand: what is connected to what?

To simplify Debian users' life, here is the

Step by step installation manual

Install Debian 7 'Wheezy' (I'm using AMD64 version). Straight forward process: http://www.debian.org/releases/stable/amd64/ . Nothing special.

After finishing installation, open Terminal (in GNOME 3: Activities -> Applications -> Terminal).

Log in as root:
$ su -l
If you disabled root login during the installation process, you may run $ sudo bash OR insert sudo in front of the following commands.

Now add the new architecture i386:
# dpkg --add-architecture i386
# aptitude clean && aptitude update

Install libpulse:
# aptitude install libpulse0 libpulse0:i386

Then, download Skype:
# wget -O skype-install.deb http://www.skype.com/go/getskype-linux-deb

WARNING: Fork: Here this manual way diverges from presented one at Debian Wiki!

Install Skype dependencies:
# dpkg-deb --field skype-install.deb Depends
# aptitude install <every package from the dpkg-deb output, adding :i386 suffix>

Closing the finish line, install Skype itself:
# dpkg --install skype-install.deb

The last thing to do is to enable "[x] Check for update on startup" in the ‘Advanced’ tab of the options menu in Skype. In this case Skype will notify you about new versions.

That's all! :) Enjoy!


Photos I made during my visit to OU @ Athens, OH in February, 2013

Hi all,

Hope you are doing well.

Here are the photos I made during my visit to Dept. of Physics & Astronomy, Ohio University, Athens, OH in February.

It was an awesome experience! Prof. Charlotte Elster compared Athens with small German towns. I never was at Germany, but expect to see something like this.

Just before couple of days before my arrival the temperature fell down to -16 Celsius. Fortunately, during February the lowest temperatures were about -9 C only.

More photos are on the way.


Google Reader, RIP

Just finished reading the news from the feed of Google Reader. That's all.

Google Reader, RIP... Thanks for a good service!


Bye-bye, Google Reader! One more out...

One of my friends commented post "Bye-bye, Posterous!", delivering the news that Google Reader is on the last lap too:


One more is out... That's sad. How shall I read the news now?...


By-bye, Posterous!

On April 30th, we will turn off posterous.com and our mobile apps in order to focus 100% of our efforts on Twitter. This means that as of April 30, Posterous Spaces will no longer be available either to view or to edit.
I used this service during about 2 years to easily publish my posts. That's sad, but they are closing down.

Bye-bye, Posterous!


Way to Athens, Ohio


About a week ago I made my way to Athens, Ohio. Now I got the time to share the photos:


After the Texas weather, the snow really shakes your mind! :)
