Below chart is taken from Stress That Doesn’t Pay: The Commuting Paradox, August 2004, page 30. The data is per 2000/2001.
The above document links these numbers with reported satisfaction with life — longer commuting times means less happiness.
On Ubuntu install with:
apt-get install gnupg
First generate private and public key:
Generating this key can take some time, because it needs enough randomness.
Store your public key in a file:
gpg -a --export
Although it is not necessary to store this public key, you usually will provide this public key to other people, see for example my public key.
Import public keys from other people by
gpg --import my-friend.pub
Now encrypt a message for my-friend:
gpg -aers my-friend your-file
These options have the following effect:
-a: create base64 encoded output (“ASCII armored”). This is not necessary, so you can skip this option. If skipped the output is binary.
-r: recipient, here your-friend
-s: add signature. This is not necessary. You could drop this option from above.
Decrypting a file is the easiest part. Just type
Im(Press)ive! Your Year in Review published some usage statistics for the year 2014, which are quite astonishing:
Compare this with statistics from year 2013:
So WordPress.com is not only growing, they are growing faster than last year.
Downloading the Boost C++ library is occasionally hindered by various company policies.
boost_1_57_0.7z.rc4.b64 is Boost version 1.57.0 (MD5 is 17c98dd78d6180f553fbefe5a0f57d12) in the following format:
Encryption and encoding was done like this
openssl enc -rc4 -a -in boost_1_57_0.7z -out boost_1_57_0.7z.rc4.b64
Decrypting goes like this:
openssl enc -d -rc4 -a -in boost_1_57_0.7z.rc4.b64 -out unencrypted.7z
Parallel Programming and Applied Mathematics, PPAM for short, is a biennial conference started in 1994, with the proceedings published by Springer in the Lecture Notes in Computer Sciences series, see PPAM. It is sponsored by IBM, Intel, Springer, AMD, RogueWave, and HP. The last conference had a fee of 420 EUR.
It is held in conjunction with 6th Workshop on Language based Parallel Programming.

SLURM is a job-scheduler for Linux. It is most useful if you have a cluster of computers. But if you only have two or three computers it can be put to good use. SLURM is an acronym for Simple Linux Utility for Resource Management.
SLURM is used by Tianhe-2, the most powerful supercomputer in the world with 3,120,000 Intel Xeon E5 2.2 GHz cores (not CPUs). It is in effect a combination of 16,000 computer nodes. Tianhe-2 is located in Guangzhou, China. SLURM is also used by Odyssey supercomputer at Harvard with 2,140 nodes equipped with AMD Opteron 6376 CPUs. Frankfurt’s supercomputer with 862 compute nodes, each equipped with AMD Opteron 6172 processors, also uses SLURM. Many other HPC sites use SLURM.
What is the catch of a job-scheduler? While a single operating system, like Linux, can manage jobs on a single machine, the SLURM job-scheduler can shuffle jobs around lots of machines, thereby even out the load on all of them.
