Visualize Your Hard Drive to Free Space

It’s sometimes difficult to find out what’s taking up all your computer hard drive space. That’s why I like these free programs which visually display the contents of your hard drive by file size. These programs make it easy to find and delete large files and directories that you no longer need.

For Windows – Disk Space Fan

Disk Space Fan shows you a beautiful fan of your hard drive space. Here’s a video of how it works. When you install the free version, it allows you to use the Pro version for free for 15 days, then it reverts to the free version automatically. All the basic tools are included in the free version though.

UPDATE: Daniel in the comments alerted me to the fact that Disk Space Fan is a ripoff of the Mac app DaisyDisk available at http://daisydiskapp.com.

For Mac – GrandPerspective

GrandPerspective for Mac OS X is similar to Disk Space Fan but chooses the box metaphor to visually display your files. The first segment of this video explains how it works.

For more ideas on saving hard disk space, look at the Lifehacker article How to Analyze, Clean Out, and Free Space on Your Hard Drive.

Play Music at Retail Legally

Background Music at the Store

I recently helped install a stereo system for a retail store in Virginia. They wanted to play background music for their customers but weren’t sure what they could play. In the US, it’s illegal to play the radio or regular CDs because those songs aren’t licensed to be played for “public performance.” (UPDATE: Thanks to John Kaufeld who corrected me in the comments regarding radio play)

What happens if you play regular music CDs at your business? You might get a visit from the American Society of Composers, Authors and Publishers (ASCAP), Broadcast Music Incorporated (BMI), or the Society of European Stage Authors and Composers (SESAC). One retailer I know of was fined $7000 by ASCAP for playing music which was not properly licensed.

Legal Options

So how do you play music legally in the public? Here are some options.

  1. Purchase business-licensed music CDs. Many retailers buy muzak, the horrible elevator music, because it’s cheaper to license than the actual songs. Please don’t do this.
  2. Get XM Radio for Business, costing $40/month.
  3. Download free music from Jamendo which is under a Creative Commons license.  This music is uploaded by artists that are not represented by ASCAP/BMI/SEAC. I am amazed at the number of high quality albums listed on Jamendo. My Virginia client found lots of great jazz at Jamendo and will play that at their retail store.

ASCAP is Nuts

As a side note, I am all in favor of musicians getting their due. But hearing background music in a store falls under “fair use” to me. From a music business prospective, I don’t think that many people will chose to listen to music in a store as a replacement for buying music. “Hey honey, let’s go to the mall. I feel like listening to some Lady Gaga.” Hearing music at a store promotes music purchases just like hearing it on the radio.

ASCAP goes way too far. They’ve sued Boy Scouts and Girl Scouts for singing camp songs. They’ve sued cell phone users for playing ring tones. They want fees from YouTube for having background music in videos. They want fees from iTunes and Amazon for 30-second song previews. That’s not just silly. It hurts the musicians.

10 Fixes for Overheating Laptops

Many PC laptops are poorly designed, causing them to overheat and turn off automatically to keep from becoming damaged. Here are a few possible fixes:

1. Remove Dust

Dust often forms around fans and air vents, reducing airflow and cooling. Start with a vacuum cleaner to pull out loose dust. Then blow out the remaining dust with a can of compressed air.

2. Keep Vents Open

Be sure to never cover the fans and air vents. The small holes under the laptop are needed for the components to properly cool. Placing a laptop on a pillow or bed will smother the vents and stop airflow. If you do use the laptop on a bed, carpet, etc, at least place it on a board or other smooth surface so that the laptop can use the designed airflow.

3. Raise the Laptop

Raise the laptop to allow more air to flow underneath. Don’t do this in a way that covers the air vents. For example, four rubber furniture raisers bought a hardware store will cheaply raise a laptop. For more cheap options, see the Lifehacker Top 10 DIY Laptop Stands.

4. Add Active Cooling

For more money, you can buy a notebook cooling pad such as the Targus Lap Chill Mat or Cooler Master Notepal U2. These raise the laptop and have fans which move air under the laptop.

With one customer, I needed to get the data off of a quickly overheating laptop so I placed it onto trays of ice. I placed a sheet of plastic over the ice to reduce humidity seeping up to the laptop. It wasn’t a long-term solution but was able to keep the laptop running for a few hours.

5. Download BIOS and Software Updates

Typically available from the laptop manufacturer, BIOS and OS driver updates can fix CPU and fan control problems.

6. Configure the BIOS

Check to see what BIOS options exist for the CPU and GPU. You typically get into the BIOS by clicking F1, F2 or ESC when you first turn the computer on.  Sometimes there are options to underclock the CPU or step down the processors.

Fan speeds and temperature alarms can sometimes also be set in the BIOS.

7. Configure Windows Power Options

Within Power Options (Control Panel – Power Options), you can set the laptop to run using less power for both the CPU and graphics card. This will slow down the computer but also lower its heat.

8. Install Monitoring Software

Speedfan is free Windows software allowing you to see the temperature of components. Knowing the CPU temperature can be helpful when trying to improve cooling. Depending on the system, Speedfan might be able to control and modify the fan speed.

9. Fix the Thermal Compound

The thermal compound between the CPU and heat sink is often poorly applied during manufacture. If you want to fix an overheating CPU and are adventurous, you can open the laptop, remove the CPU, clean it and the heat sink, apply new thermal paste, and put everything back together. This is not a simple process, even for people who do it regularly. But it can permanently fix some overheating computers.

10. Internet Search For Your Laptop Model

Particular laptop models are typically susceptible to the same problems. A recent customer has a Gateway M1625, commonly afflicted with overheating on the left side due to poor CPU thermal paste. Many Sony models were recently identified as having an overheating problem that Sony is fixing through software. A fix for your laptop might be found with a quick Internet search.
