(NSFW, Gore) “Enough talk.” Auralnauts tallies the huge number of lives taken by Arnold Schwarzenegger’s different characters over his 44-year career. It’s also a sobering reminder of just how bad he is as an actor. My goodness.

Macro photography is like a secret world. You can capture ordinary objects in a way that the human eye cannot see them, and create captivating images. Many people immediately think flowers and bugs at the mention of the word macro, but there are so many other great options. This is meant to inspire you to […]

It’s a Small World – the World of Macro Photography

A new NBER working paper (abstract; PDF) analyzes Warren Buffett‘s Berkshire Hathaway and the drivers of its stock market success. Beyond benefiting from Buffett’s ability to buy low and sell high, Berkshire has also been able to borrow cheaply: 

Berkshire Hathaway has realized a Sharpe ratio of 0.76, higher than any other stock or mutual fund with a history of more than 30 years, and Berkshire has a significant alpha to traditional risk factors. However, we find that the alpha becomes insignificant when controlling for exposures to Betting-Against-Beta and Quality-Minus-Junk factors. Further, we estimate that Buffett’s leverage is about 1.6-to-1 on average. Buffett’s returns appear to be neither luck nor magic, but, rather, reward for the use of leverage combined with a focus on cheap, safe, quality stocks. Decomposing Berkshires’ portfolio into ownership in publicly traded stocks versus wholly-owned private companies, we find that the former performs the best, suggesting that Buffett’s returns are more due to stock selection than to his effect on management. These results have broad implications for market efficiency and the implementability of academic factors.

Why Warren Buffett Rocks

In case you missed Norvald’s post, the official yum repos now support the 5.7 development releases!
The MySQL manual documents how you can enable 5.7, but I wanted to also provide a quick demonstration since using yum sub-repositories is a new concept to me.
Installing the repo
All versions of MySQL are downloaded via a single repo file, which can be downloaded from: http://dev.mysql.com/downloads/repo/.
You can copy the URL from the download page directly into a yum localinstall command. For example on Enterprise Linux 6, the command is:
sudo yum localinstall http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
Activating MySQL 5.7
The default version of MySQL enabled with the repo will be MySQL 5.6 GA. The documented way to change this to 5.7 is:
shell> sudo yum-config-manager –disable mysql56-community
shell> sudo yum-config-manager –enable mysql57-community-dmr
You also have the option to manually edit the sources.list file, which if you run the above commands will now contain:
[root@mysqlrpm ~]# cat /etc/yum.repos.d/mysql-community.repo
[mysql-connectors-community]
name=MySQL Connectors Community
baseurl=http://repo.mysql.com/yum/mysql-connectors-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

baseurl=http://repo.mysql.com/yum/mysql-tools-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
# Enable to use MySQL 5.5
[mysql55-community]
name=MySQL 5.5 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.5-community/el/6/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
# Enable to use MySQL 5.6
[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
# Note: MySQL 5.7 is currently in development. For use at your own risk.
# Please read with sub pages: https://dev.mysql.com/doc/relnotes/mysql/5.7/en/
[mysql57-community-dmr]

enabled=1
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
From there, a yum install will show MySQL 5.7 as the intended version to be installed:
[root@mysqlrpm ~]# yum install mysql-community-server

This one exercise can greatly improve your mobility and flexibility—and cure the many ills that come from sitting hunched in front of a screen all day. It takes just 30 seconds and you don’t need any equipment.

Max Shank teaches us how to do this move, called the Thoracic Bridge. It basically opens up your body and can help with pain and tightness in your shoulders, back, and hips. It looks a little weird to do, but when you get the hang of it, you should automatically feel the difference in your body’s alignment and posture. (Also, you don’t have to be as crazy acrobatic as Max in switching sides.)

There are lots of easy stretches you can do to correct your hunching and get all the benefits of better posture, but if you’re only going to do one thing, the Thoracic Bridge move is arguably the best one since it corrects so many issues in half a minute.
