Stabilized Footage of the JFK Assassination Is Unsettlingly Real

When it’s bouncing around and playing back at a jittery 18 frames per second, the infamous Zapruder footage of John F. Kennedy’s assassination feels almost unreal. But when it’s stabilized with additional interpolated frames bringing it to a steady 30 frames per second (like we’re used to seeing on TV) it suddenly becomes much more real.

7 Productivity Boosting Keyboard Shortcuts Every Mac User Should Know

We love our keyboard shortcuts, as they help us get around our computers much faster every day. Here are seven you may not know about on the Mac that can boost your productivity by making navigation easier and performing tasks faster.

Check out the video above for a demonstration of each shortcut, or a list below for our choices:

  • Command+Shift+A/U/D: These three-in-one shortcuts take you to the Applications, Utilities, and Desktop folders (respectively) when in the Finder. Because you’ll need to get to each relatively often, this key command can save you quite a bit of time.
  • Command+1/2/3/4: When you need to change views in the finder, you don’t have to bother with your mouse. 1 will get you icon view, 2 list view, 3 column view, and 4 cover flow.
  • Command+Option+I: When you need info on multiple files, just select them and execute this key command. You’ll get an info panel about everything currently selected.
  • Command+Shift+4 and Space: When you press Command+Shift+4 you get to take a screenshot of a specific area on the screen. If you hit the space bar afterwards, however, you can click on any window to get a nice PNG with transparent background of that window.
  • Command+Option+M: Sometimes you end up with too many windows on your desktop and you just want to cut your losses. Minimize them all to the dock with this keyboard shortcut.
  • Command+(Shift)+~: If you’d rather cycle through millions of windows, you can use this key command to do so. Add or remove the shift key to change directions.
  • Command+Option+Space: Most of us know that you can search Spotlight quickly by pressing Command+Space. Add the option key to get a Spotlight search window and get more specific about what you’re trying to find.

OS X has plenty of awesome shortcuts and they certainly don’t stop after seven. These, however, will help you get around your Mac a little bit faster and have similar structures so they’re easy to remember.

Upgrading from the earlier MySQL RPM Format to Yum Repos

The packages that are available in the yum repos contain a number of enhancements over the RPM packages that are available from dev.mysql.com.
Norvald blogged on some of these enhancements earlier. Today I wanted to walk through a safe upgrade path, as they are not quite compatible with each-other.
My Existing Installation
To start with, the packages I have installed came from “Red Hat Enterprise Linux 6 / Oracle Linux 6 (x86, 64-bit), RPM Bundle” on dev.mysql.com. You can check which packages you have installed with:
[root@localhost ~]# rpm -qa | grep -i mysql
MySQL-client-5.6.14-1.el6.x86_64
MySQL-embedded-5.6.14-1.el6.x86_64
MySQL-server-5.6.14-1.el6.x86_64
MySQL-shared-5.6.14-1.el6.x86_64
MySQL-devel-5.6.14-1.el6.x86_64
MySQL-test-5.6.14-1.el6.x86_64
MySQL-shared-compat-5.6.14-1.el6.x86_64
Uninstalling and Installing Yum repos
I recommend first running yum update before installing the new repo:
yum update
yum localinstall http://repo.mysql.com/mysql-community-release-el6-3.noarch.rpm
After this step, stop MySQL (note the missing d in the dev.mysql.com packages):
service mysql stop
Now with yum shell it’s possible to uninstall the existing packages (listed in ‘my existing installation’ above) and install the replacement packages from the yum repo in one step:
yum shell
> remove MySQL-client-5.6.14-1.el6 MySQL-embedded-5.6.14-1.el6 MySQL-server-5.6.14-1.el6 MySQL-shared-5.6.14-1.el6 MySQL-devel-5.6.14-1.el6 MySQL-test-5.6.14-1.el6 MySQL-shared-compat-5.6.14-1.el6 > install mysql-community-server
> run
Here was the summary output from my yum session:
============================================================================================================================
Package Arch Version Repository Size
============================================================================================================================
Installing:
mysql-community-server x86_64 5.6.14-3.el6 mysql-community 51 M

MySQL-test x86_64 5.6.14-1.el6 @/MySQL-test-5.6.14-1.el6.x86_64 318 M
Installing for dependencies:

postfix x86_64 2:2.6.6-2.2.el6_1 @anaconda-CentOS-201303020151.x86_64/6.4 9.7 M
Transaction Summary
============================================================================================================================
Install 4 Package(s)
Remove 11 Package(s)
MySQL should now be installed from the yum packages. You just have two more steps to complete – start it, and configure it on boot:
service mysqld start # note the added ‘d’
chkconfig mysqld on
Still having problems? I recommend heading to the MySQL Forums. There is a section dedicated to Install & Repo help.

Override Your Hotel Room Thermostat and Set It As Hot or Cold You Like

Hotel room thermometers normally don’t let you adjust the temperature above or below a certain point, which can lead to some pretty warm rooms in the summer time or chilly ones in the winter. If you want more control, here’s how to override your hotel thermometer, put it in "VIP" mode, and tweak it where you like it.

Gary Leff, writing for View from the Wing, shared the video above, which shows you how it’s done. Most hotel wall units (Gary noted that Hilton and Hyatt specifically tend to use this type of thermostat) that you’ll have access to will work this way. The window units on the air conditioner/heaters themselves may be a bit more flexible, but give this a try on your next wall thermometer:

  • Hold down the “display” button
  • While holding that button, press “off”
  • Release off, continue to hold down display, and Press the “up” arrow button
  • Release all buttons

This trick also disables the motion sensors that many hotels use to only keep the heating and cooling system active at all when a guest is in the room—that means that you won’t have to wait for a sweltering room to gradually cool off when you get back from a long day, or wait for an ice cold room to warm up in the winter.

Gary explains that you don’t have to just be quirky about the temperature to use this trick—sometimes hotels try and save money by keeping the room thermostats in a certain range, leading to uncomfortable guests, and in his case, he had a room that got a ton of sunlight that warmed it up in the daytime, making it really hot, even with the thermostat turned down as far as it can go. Either way, the power is yours—to be more comfortable when you travel. Hit the link below to read more—his commenters, both at the link below and his much older post have some similar tricks for other hotel chains that may not use these units, too.
